RESUMO

Background: Oral squamous cell carcinoma (OSCC) is gradually increasing its incidence in our society. Unfortunately, this entity is diagnosed at an advanced stage in most patients, a fact that implies greater difficulty in its treatment and a worse prognosis. This systematic review aims to assess whether the cytokines IL-6, IL-8 and TNF-α are potential salivary biomarkers that allow early diagnosis of cancer. Material and methods: An electronic search was performed in three databases (Pubmed, Scopus and Web of Science). We used the following keywords: "salivary cytokines", "saliva cytokines", "salivary interleukins", "biomarkers", "oral squamous cell carcinoma" and "diagnosis", combined with the Boolean operators "AND" and "OR". Results: 128 publications were found and finally 23 articles were included in the review and 15 in the meta-analysis. It has been observed that the majority of OSCC patients express higher salivary concentrations of IL-6, IL-8 and TNF-α compared to the control (CL) and premalignant lesion (OPML) groups. It has also been observed that the different premalignant lesions do not have statistically significant differences in the salivary concentration of the cytokines, and on the other hand, differences have been observed between the different TNM stages. The meta-analysis has shown that the difference in concentration of IL-6, IL-8 and TNF-α is statistically significant between the CL group and the OSCC, and also between the CL group and OPML. Conclusions: There is sufficient evidence to affirm that IL-6, IL-8 and TNF-α are useful salivary cytokines in the early diagnosis and prognosis of OSCC. Although future studies are necessary to establish greater reliability of these biomarkers and thus be able to develop a valid diagnostic test. (AU)

RESUMO

Objective: This study aimed to explore the effect of individualized positive end-expiratory pressure (PEEP) on postoperative pulmonary complications (PPCs) in elderly patients with prostate cancer undergoing general anesthesia in Trendelenburg position (low-head and high-foot position at about 45° when patients were in supine position). Methods: The clinical data of 96 elderly patients undergoing Leonardo’s robotic-assisted laparoscopic radical prostatectomy in Zhejiang Provincial People’s Hospital from October 2021, to April 2023, were selected for retrospective analysis. Sixteen patients who had interrupted follow-up or did not meet the inclusion criteria were excluded, and 80 patients were finally included. The patients were divided into group A (lung-protective strategy using routine PEEP value, n = 40) and group B (lung-protective strategy using individualized PEEP value, n = 40) on the basis of different inversion methods. The PEEP value of group A was set as 5 cmH2O, whereas that of group B was determined under the guidance of static lung compliance. The incidences of PPCs on postoperative day 7 were statistically analyzed, and the serum levels of interleukin (IL) 6 (IL-6) and IL-8 in both groups were measured by enzyme-linked immunoadsordent assay (ELISA). Results: The incidence of pulmonary complications was obviously lower in group B than in group A on postoperative day 7 (p < 0.001). Group B had lower levels of serum IL-6 and IL-8 at the end of surgery (T1) and 12 h after surgery (T2, p < 0.001); Higher oxygenation index values 10 min after successful titration of individualized PEEP (A3), 1 h after individualized PEEP ventilation (A4), 2 h after individualized PEEP ventilation (A5), 10 min after recovery of supine position (A6), and 30 min after tracheal extubation (A7); And lower hospitalization time (all p < 0.001) than group A (AU)

RESUMO

Introduction and objectives: There are controversial results regarding the value of serum IL-8 and TNFα in patients with non-specific low back pain. This study aimed to compare pro-inflammatory cytokines between patients with non-specific back pain and pain-free controls. Materials and methods: We conducted a case–control study including 106 participants: 46 patients with chronic non-specific low back pain (G1) and 60 pain-free controls (G0). The interleukin (IL-)6, IL-8, IL-17, IL-23, IL-22, and Tumor necrosis factor α (TNFα) were measured. We collected demographic and clinical data, including age, gender, low back pain duration and radicular pain. The pain degree was assessed using the Visual Analogic Scale. Results: The mean age was 43.17±8.7 years in G1. Radicular pain was found in 37 cases with a Visual Analogic Scale of 3.03±2.5mm. The magnetic resonance imaging was performed in (G1), showing disk herniation and degenerative disk disease in 54.3% (n=25) and 45.7% of cases (n=21), respectively. The IL-8 was higher in G1 (18.84±44.64 versus 4.34±1.23pg/mL, p:0.033). IL-8 levels correlated with TNFα (0.942, p<10–3), IL-6 (0.490, p=0.011) and Visual Analogic ScaleRadicular-pain (r:0.297, p:0.047). IL-17 was higher in patients with restricted lumbar spine mobility (9.64±20.77 versus 1.19±2.54pg/mL, p:0.014). Conclusions: Our results provide evidence that IL-8 and TNFα play a role in low back pain and radicular pain due to disk degeneration or herniation. These findings could potentially be used by future studies to develop new non-specific low back pain therapeutic strategies.(AU)


Introducción y objetivos: Existen resultados controvertidos en cuanto al valor de la interleucina (IL) 8 y el factor de necrosis tumoral α (TNFα) séricos en pacientes con lumbalgia inespecífica. Este estudio tuvo como objetivo comparar las citoquinas proinflamatorias entre pacientes con dolor de espalda inespecífico y controles sin dolor. Materiales y métodos: Realizamos un estudio de casos y controles que incluyó a 106 participantes: 46 pacientes con dolor lumbar crónico inespecífico (G1) y 60 controles sin dolor (G0). Se midieron las IL-6, IL-8, IL-17, IL-23, IL-22 y el TNFα. Recopilamos datos demográficos y clínicos, incluidos la edad, el sexo, la duración del dolor lumbar y el dolor radicular. El grado de dolor se evaluó mediante la escala analógica visual. Resultados: La edad media fue de 43,17±8,7 años en G1. Se encontró dolor radicular en 37 casos con una escala analógica visual de 3,03±2,5mm. La resonancia magnética se realizó en G1, mostrando hernia discal y enfermedad discal degenerativa en el 54,3% (n=25) y el 45,7% de los casos (n=21), respectivamente. La IL-8 fue mayor en G1 (18,84±44,64 versus 4,34±1,23pg/ml, p=0,033). Los niveles de IL-8 se correlacionaron con TNFα (0,942, p<10−3), IL-6 (0,490, p=0,011) y escala visual analógicadolor radicular (r=0,297, p=0,047). IL-17 fue mayor en pacientes con movilidad restringida de la columna lumbar (9,64±20,77 versus 1,19±2,54pg/ml, p=0,014). Conclusiones: Nuestros resultados proporcionan evidencia de que la IL-8 y el TNFα juegan un papel en el dolor lumbar y en el dolor radicular debido a la degeneración o a hernia discal. Estos hallazgos podrían potencialmente ser utilizados por estudios futuros para desarrollar nuevas estrategias terapéuticas no específicas para el dolor lumbar.(AU)

RESUMO

Background and objectives: Systemic sclerosis (SSc) is an autoinmune disease that can affect several organs and its mortality is fundamentally related to its pulmonary involvement. There are some cytokines with high serum levels of patients with SSc. Our goal is to determine the role of CXCL4, CXCL8 and GDF15 in the physiopathology of SSc and whether they can be considered organic damage biomarkers.Patients and methodsObservational case–control study of SSc patients (ACR/EULAR 2013 criteria). Demographic, clinical, analytical, activity, severity, health perception, and disability variables were collected. Moreover, Videocapillaroscopy, Echocardiography and Respiratory Function Test were made. Serum levels of CXCL4, CXCL8 and GDF15 were measured both in SSc patients and in healthy controls.ResultsA total of 42 patients were included (95.4% women), with an average age of 59.2 years and a median of 4 years from diagnosis. We also included 42 healthy controls. We found significantly higher levels of GDF15 in SSc patients than in controls (p<0.001), but no higher CXCL4 or CXCL8 levels. GDF15 was associated with Diffuse SSc, pulmonary arterial hypertension, interstitial lung disease, less forced vital capacity, high titles of antiScl70, disease activity, and dilated loops in capillaroscopy. CXCL4 levels were associated to a higher Rodnan punctuation, while CXCL8 was associated to C4 fraction consumption and tortuosities in capillaroscopy. (AU)


Antecedentes y objetivos: La esclerosis sistémica (ES) es una enfermedad autoinmunitaria que afecta a diferentes órganos y cuya mortalidad se relaciona fundamentalmente con su afectación pulmonar. Los pacientes con ES presentan niveles séricos elevados de algunas citocinas. Nuestro objetivo es determinar el papel de CXCL4, CXCL8 y GDF15 en la fisiopatología de la ES, y si pueden considerarse biomarcadores de daño orgánico.Pacientes y métodosEstudio observacional de casos-controles, con pacientes afectados de ES (criterios ACR/EULAR 2013) y controles sanos. Se determinaron los niveles séricos de CXCL4, CXCL8 y GDF15 en ambos grupos, y se registraron variables demográficas, clínicas, analíticas, de actividad, gravedad, percepción de salud y discapacidad de pacientes con ES, a quienes, además, se les realizó videocapilaroscopia, ecocardiograma y espirometría.ResultadosSe incluyeron 42 pacientes (95,4% mujeres), con una edad media de 59,2 años y una mediana de 4 años desde el diagnóstico, con 42 controles sanos. Se hallaron niveles significativamente mayores de GDF15 en pacientes con ES que en controles (p<0,001), pero no de CXCL4 ni CXCL8. GDF15 se asoció a ES difusa, hipertensión pulmonar, enfermedad pulmonar intersticial, menor capacidad vital forzada, títulos altos de anti-Scl70, actividad de ES y dilataciones capilares. Asimismo, los niveles de CXCL4 se asociaron a mayor afectación cutánea (Rodnan), mientras que CXCL8 se asoció a consumo de la fracción C4 del complemento y tortuosidades en la capilaroscopia. (AU)

RESUMO

BackgroundGastric cancer (GC) is a malignancy that belongs to one of the most common leading causes of cancer death. Cancer-associated fibroblasts (CAFs) promote the GC cells’ malignant behavior. It is still unknown how GC converts normal fibroblasts (NFs) to CAFs.MethodsGC cells were co-cultured with NFs. Bioinformatics was used to analyze the genes and signaling pathways that were changed in fibroblast. RT-PCR, western blot, and Elisa assays were used to detect the expression of cytokines in fibroblast and condition medium. Western blot and immunofluorescence demonstrated activation of relevant pathways in CAFs-like cells. Transwell, scrape, colony formation, and CCK-8 assays were performed to reveal the feedback effect of CAFs-like cells on GC cells.ResultsGC promoted the conversion of NFs to CAFs by secreting Interleukin 17A (IL-17). It included both morphological and molecular marker changes. This process was achieved by activating the nuclear factor-κB (NF-κB) pathway. On the other hand, CAFs cells could secrete C-X-C Motif Chemokine Ligand 8 (IL-8, IL-8), which promoted the malignant phenotype of GC cells. In this way, a feedback loop of mutual influence was constructed in the GC and tumor microenvironment (TME).ConclusionsOur research proved a novel model of GC-educated NFs. GC-IL-17-fibroblast-IL-8-GC axis might be a potential pathway of the interaction between GC and TME.

RESUMO

La diabetes mellitus tipo 2 (DMT2) es una enfermedad caracterizada por un estado inflamatorio crónico en la que algunos marcadores como las concentraciones de lípidos se han encontrado frecuentemente alterados. Se han descrito otros marcadores de inflamación alterados como las interleucinas 6, 8 y el factor de necrosis tumoral, sin embargo, existe poca información acerca del comportamiento del índice neutrófilo/linfocito (INL), la relación plaquetas/linfocitos (RPL) y el índice monocitos/linfocitos (IML), los coeficientes lipídicos y el índice aterogénico en pacientes con DMT2. Objetivo: Describir los parámetros aterogénicos y de inflamación en un grupo de pacientes con DMT2. Materiales y métodos: Se incluyeron y analizaron los antecedentes clínicos (antecedentes de la enfermedad, comorbilidad, tabaquismo y otras variables relevantes), así como parámetros hematológicos, bioquímicos y antropométricos de 42 pacientes, y se calcularon y evaluaron los coeficientes aterogénicos e índices de inflamación. Resultados: Se encontraron concentraciones elevadas de citocinas proinflamatorias IL-6 e IL-8, factor de necrosis tumoral-α y elevado INL. El 88% de los pacientes fueron clasificados como de alto riesgo de acuerdo con el índice aterogénico. Los pacientes exfumadores exhibieron niveles menores de IL-8 y niveles más altos de INL comparados con los que nunca han fumado. Conclusión: La evaluación de marcadores aterogénicos y de inflamación tales como el índice aterogénico, IL-8 y la INL permiten identificar a un subgrupo de pacientes con un alto riesgo de complicaciones graves y mortalidad.

Type two diabetes mellitus (T2DM) is characterized by a chronic inflammation status. Altered markers such as lipid concentrations are usually found in this disease. Elevated inflammation markers have been described such as cytokines (interleukin 6, tumour necrosis factor-alpha, and IL-8). However, there is a lack of information about the behaviour of the neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), lymphocyte-monocyte ratio (LMR), lipid coefficients, and atherogenic index in T2DM. Objective: To describe the atherogenic and inflammation parameters in a group of patients with T2DM. Materials and methods: 42 patients with T2DM were included, all patients were surveyed on clinic history (disease history, comorbidity, smoking, and other relevant variables), measurements of haematological, biochemical, and anthropometric parameters were taken and atherogenic coefficients and inflammation ratios were calculated. Results: Inflammation markers such as interleukin 6 and 8, necrosis tumour factor, and NLR were elevated. Of the patients, 88% were classified as high risk according to the atherogenic index. Former smokers had lower levels of IL-8 and higher NLR than non-smokers. Conclusion: The atherogenic and inflammation markers such as atherogenic index, IL-8, and NLR make it possible to identify a subgroup of patients that are at risk of severe complications and mortality.

RESUMO

Objetivo: Analizar la relación entre la expresión transcripcional de interleucina-8 (IL-8) y la respuesta al tratamiento con radioterapia o quimio-radioterapia en pacientes con carcinoma escamoso de cabeza y cuello (CECC).Material y métodosEstudio retrospectivo realizado a partir de biopsias de tumor obtenidas de forma previa a un tratamiento con radioterapia o quimio-radioterapia en 87 pacientes con CECC. Se dispuso de una muestra de mucosa sana en 35 ocasiones. Se determinó la expresión transcripcional de la IL-8 mediante RT-PCR. Se categorizó el nivel de expresión transcripcional de IL-8 en función del control local de la enfermedad mediante un análisis de partición recursiva.ResultadosLa expresión transcripcional de IL-8 en el tejido tumoral fue unas 50 veces superior al de las muestras de mucosa sana. La supervivencia libre de recidiva local a los 5años para los pacientes con una expresión transcripcional elevada de IL-8 (n=56) fue del 65,6%, y para los pacientes con una expresión baja (n=31) del 90,2% (p=0,017). De acuerdo con los resultados de un análisis multivariante, los pacientes con unos niveles de expresión elevada de IL-8 contaron con un riesgo 4,1 veces superior de recidiva local de la enfermedad.ConclusionesLos CECC cuentan con un incremento significativo en los niveles de expresión transcripcional de la IL-8 en relación con el tejido no tumoral. Los tumores con unos niveles de expresión elevados de IL-8 tienen un incremento en el riesgo de sufrir una recidiva local del tumor tras un tratamiento con radioterapia o quimio-radioterapia. (AU)


Objective: To analyse the relationship between the transcriptional expression of interleukin-8 (IL-8) and response to treatment with radiotherapy or chemo-radiotherapy in patients with squamous cell carcinoma of the head and neck (SCCHN).Material and methodsRetrospective study from tumour biopsies obtained before a treatment with radiotherapy or chemo-radiotherapy in 87 patients with SCCHN. We had a sample of healthy mucosa in 35 cases. We determined the transcriptional expression of IL-8 with RT-PCR. The transcriptional expression of IL-8 was categorized according to the local control of the disease with a recursive partitioning analysis.ResultsThe transcriptional expression of IL-8 in tumour tissue was about 50 times higher than that in the samples of healthy mucosa. Patients with a high transcriptional expression of IL-8 (n=56) had a 5-year local recurrence-free survival of 65.6%, and for patients with low expression (n=31) it was 90.2% (P=.017). According to the results of a multivariate analysis, patients with high expression of IL-8 had a 4.1 higher risk of local recurrence of the tumour.ConclusionsSCCHN have a significant increase in transcriptional expression of IL-8 in relation to non-tumour tissue. Tumours with high IL-8 expression have an increased risk of local recurrence after treatment with radiotherapy or chemo-radiotherapy. (AU)

RESUMO

Background Chronic obstructive pulmonary disease (COPD) is related to inflammation and obstruction of the lungs and airways. Protein arginine methyltransferase 5 (PRMT5) that promotes arginine methylation of histones is associated with inflammation of endothelial cell and is implicated in lung branching morphogenesis and progression of lung cancer. The mechanism of PRMT5 in inflammatory response of COPD was explored in this study. Methods Human bronchial epithelial cells, 16HBE, were treated with cigarette smoke extract for 24 h to establish cell model of COPD. Cell viability was examined by MTT assay. Western blot and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) assays were used to explore expression of PRMT5. Expression of Interleukin (IL)-6, IL-8, tumor necrosis factor-α (TNF-α), and IL-1β were investigated by enzyme-linked-ithe mmunosorbent serologic assay. Results Cigarette smoke extract treatment induced cytotoxity of 16HBE with reduced cell viability. PRMT5 was enhanced in cigarette smoke extract-induced 16HBE. Knockdown of PRMT5 increased cell viability of cigarette smoke extract-induced 16HBE, and attenuated cigarette smoke extract-induced increase of IL-6, IL-8, TNF-α, and IL-1β. Up-regulation of C-X-C Motif Chemokine 10 (CXCL10) in cigarette smoke extract-induced 16HBE was restored by knockdown of PRMT5. Over-expression of CXCL10 counteracted with the suppressive effect of PRMT5 silence on expression of IL-6, IL-8, TNF-α, and IL-1β. Moreover, PRMT5 silence-induced increase of cell viability in cigarette smoke extract-induced 16HBE was reversed by over-expression of CXCL10. Conclusion Knockdown of PRMT5 promoted cell viability of cigarette smoke extract-induced 16HBE, and reduced inflammation through down-regulation of CXCL10 (AU)

RESUMO

Objetivo Aclarar la asociación entre polimorfismos del gen IL-8 y nivel de IL-8 en el riesgo de degeneración macular asociada a la edad (DMAE). Métodos Se realizó un metaanálisis a partir de los estudios disponibles que investigaron los polimorfismos de IL-8 −251A/T (rs4073) y +781C/T (rs2227306), y niveles de IL-8, en pacientes con DMAE y controles. Resultado En total, el resultado agrupado mostró una asociación significativa entre DMAE con modelos alélicos (T vs. C; OR 1,53; p = 0,005), dominantes (TT + CT vs. CC; OR 1,95; p = 0,017), homocigotos (TT vs. CC; OR 2,03; p = 0,039) y heterocigotos (CT vs. CC; OR 1,92; p = 0,032) de rs2227306; mientras que el análisis de subgrupos reveló una asociación significativa entre rs2227306 con DMAE húmedo en modelos alélicos (T vs. C; OR 1,69; p = 0,016), recesivos (TT vs. CT + CC; OR 1,81; p = 0,00007), y homocigotos (TT vs. CC; OR 2,64; p = 0,003). No se observó asociación significativa entre rs4073 con DMAE en todos los modelos de herencia. Paralelamente, los pacientes con DMAE, particularmente DMAE húmedo, tenían un nivel elevado de IL-8 en comparación con el control. Conclusión Este metaanálisis sugiere que los pacientes con DMAE o DMAE húmedo tienen niveles más altos de IL-8 en comparación con controles, lo que también está respaldado por la evidencia de que el alelo T portador de rs2227306 exhibe un aumento en el riesgo de DMAE o DMAE húmedo. Por lo tanto, el polimorfismo IL-8 +781C/T (rs2227306) y el nivel de IL-8 intraocular pueden ser útiles como biomarcadores para la detección temprana y objetivo terapéutico de DMAE (AU)


Objective To clarify the association between IL-8 gene polymorphisms, IL-8 level, towards the risk of age-related macular degeneration (AMD). Methods Meta-analysis was performed from available studies that investigated IL-8 −251A/T (rs4073) and +781C/T (rs2227306) polymorphisms and IL-8 levels in patients with AMD and controls. Result Overall, the pooled result showed a significant association between AMD with allelic (T vs. C; OR 1.53; p = 0.005), dominant (TT + CT vs. CC; OR 1.95; p = 0.017), homozygous (TT vs. CC; OR 2.03; p = 0.039) and heterozygous (CT vs. CC; OR 1.92; p = 0.032) models of rs2227306; while subgroup analysis revealed a significant association between rs2227306 with wet AMD in allelic (T vs. C; OR 1.69; p = 0.016), recessive (TT vs. CT + CC; OR 1.81; p = 0.00007), and homozygous (TT vs. CC; OR 2.64; p = 0.003) models. No significant association was observed between rs4073 with AMD in all inheritance models. In parallel, patients with AMD, particularly wet AMD had an elevated level of IL-8 compared to control. Conclusion This meta-analysis suggests that patients with AMD or wet AMD have higher IL-8 levels compared to control, which is also supported by the evidence that carrier T allele of rs2227306 exhibited an increase in the risk of AMD or wet AMD. Thus, IL-8 +781C/T (rs2227306) polymorphism and the level of intraocular IL-8 may be useful as a biomarker for early detection and a therapeutic target of AMD (AU)

RESUMO

BACKGROUND: Since 2006 breast cancer has been the leading cause of death by cancer in Mexican women. Recently several studies have shown the relationship of neutrophil-lymphocyte index (NLI) and breast cancer as a predictor of overall survival (OS) and disease-free survival (DFS). METHODS: The study included 2711 patients of the Institute of Breast Diseases (FUCAM) treated since April 2006 to March 2011. The NLI and its relation with OS and DFS were evaluated. A receiver operating characteristic curve was used to obtain the cut-off point of greater sensitivity and specificity for the NLI. A multivariate analysis was used to analyze the clinical parameters of prognostic factor. RESULTS: 342 patients were included for the analysis. The follow-up time average of 80.1 months and the mean of NLI was 2.1. In this model, sensitivity was 66.7% (95% CI: 46-64) p = 0.04. The Kaplan-Meier analysis was applied to evaluate OS and the DFS of all patients according to the NLI, comparing two groups: ≤2.1 and ≥ 2.1. No differences were reported between these groups. In triple negative patients (n=32), patients with NLI>2.1 had a shorter DFS in comparison to patients with NLI<2.1 (20 vs 55.6% in 5 years, p = 0.04). The univariate Cox risk model revealed that a NLI>2.1 pretreatment, lymph node stage and Ki-67 were correlated independently with the DFS. CONCLUSIONS: Our study suggests that there is a relationship between the NLI and the breast cancer DFS; especially in triple negative subtypes


ANTECEDENTES: El cáncer de mama tiene un enorme impacto en la salud de las mujeres. En México, desde el año 2006, el cáncer de mama ha sido la principal causa de muerte por cáncer en las mujeres mexicanas, y que representa 14% de las muertes relacionadas con el cáncer. Existen diversos factores que representan un papel importante en el desarrollo, progresión y persistencia del cáncer; entre ellos se reconoce a la respuesta inflamatoria. Múltiples estudios han demostrado la relación del índice linfocito neutrófilo (INL) y el cáncer de mama como predictor de sobrevida global y período libre de enfermedad. MATERIAL Y MÉTODOS: El diseño de estudio fue retrospectivo, transversal. Se revisaron 2.711 expedientes de pacientes con cáncer de mama tratados en el Instituto de Enfermedades de la Mama, FUCAM, en el período de abril de 2006 a marzo de 2011; se evaluó el INL previo a recibir tratamiento, y se obtuvo la relación con el período libre de enfermedad y la sobrevida global. Análisis estadístico: para obtener el punto de corte de mayor sensibilidad y especificidad para el INL se utilizó una curva de característica operativa del receptor (COR). Para variables dicotómicas se utilizó la prueba de Chi-cuadrado, mientras que para sobrevida y periodo libre de enfermedad se utilizaron las curvas de Kaplan-Meier. Un análisis multivariable se realizó para analizar el factor pronóstico de los parámetros clínicos. RESULTADOS: De la muestra inicial de 2.711, 342 cumplieron criterios de inclusión y fueron analizados. La media de edad al momento del diagnóstico fue de 51,38 años, un seguimiento promedio de 80,1 meses y la media del INL fue de 2,1. Se evaluó la sensibilidad/especificidad de la prueba para el INL, mediante la curva COR, la sobrevida libre de enfermedad y la sobrevida global. En este modelo, la sensibilidad fue del 66,7%. Al evaluar la sobrevida global y el periodo libre de enfermedad de todas las pacientes con cáncer de mama, de acuerdo al INL, comparando en 2 grupos, por INL, grupo 1, menor a 2,1 y grupo 2, ≥2,1 no se encontraron diferencias estadísticamente significativas. Se realizó otro análisis a una submuestra de pacientes con subtipo triple negativos (n=32), las que obtuvieron un INL>2,1 mostraron una menor supervivencia libre de enfermedad en comparación con los pacientes con IN<2,1 (a 5 años, 20 frente al 55,6%; p = 0,04). Al realizarse el modelo de riesgo univariante de Cox se identificó que un INL>2,1 pretratamiento, el estadio nodular y Ki-67 fueron variables que correlacionaron de manera independiente con el periodo libre de enfermedad. CONCLUSIONES: No se encontraron diferencias estadísticamente significativas en periodo libre de enfermedad, ni en sobrevida global, en pacientes con cáncer de mama agrupados acorde a INL. En la submuestra de pacientes con subtipo triple negativo (n=32), el grupo con mayor INL (> 2,1), mostró una menor supervivencia libre de enfermedad en comparación con el que tuvo menor INL (<2,1). Las variables que mostraron correlación con el periodo libre de enfermedad en este subgrupo (triple negativo), fueron un INL>2,1 pretratamiento, el estadio nodular y Ki-67

RESUMO

OBJETIVO: Estimar un nivel preciso de IL-8 en humor acuoso en pacientes con glaucoma de ángulo abierto (GAA). MÉTODOS: Se realizó un metaanálisis a partir de los estudios disponibles que investigaron el nivel de IL-8 en el humor acuoso de pacientes con GAA y sujetos de control. RESULTADOS: Se seleccionó un total de 17 estudios. El resultado agrupado mostró que los niveles de IL-8 en el humor acuoso de los pacientes con GAA fueron mayores que en los sujetos de control (DME = 0,98; IC del 95%: 0,68 a 1,27; p < 0,00001). CONCLUSIÓN: Este metaanálisis indica que los pacientes con GAA pueden tener unos niveles más elevados de IL-8 en humor acuoso en comparación con los sujetos de control, lo que apoya la noción de que la IL-8 es uno de los factores contribuyentes en el desarrollo del GAA


OBJECTIVE: To estimate an accurate level of IL-8 in aqueous humor among open-angle glaucoma (OAG) patients. METHODS: Meta-analysis was performed from available studies that investigated the IL-8 level in the aqueous humor of OAG patients and control subjects. RESULTS: A total of 17 studies were selected. The pooled result showed that IL-8 levels in aqueous humor of patients with OAG were higher than in control subjects (SMD = 0.98, 95% CI = 0.68-1.27, p < 0.00001). CONCLUSION: This meta-analysis indicates that patients with OAG may have a higher aqueous humor IL-8 levels compared to control subjects, which supports the notion that IL-8 is one of the contributing factors in the development of OAG

RESUMO

Introducción: El cáncer oral ocupa el sexto lugar entre los distintos tipos de cáncer y más del 90% corresponden al carcinoma de células escamosas de cavidad oral (CCECO). A pesar de los avances diagnósticos y terapéuticos, la tasa de supervivencia es baja debido a su diagnóstico tardío. Se han descrito técnicas alternativas al tradicional método de biopsia e histopatología, entre ellas, el uso de biomarcadores salivales. Las interleucinas-6 (IL-6) y la interleucina-8 (IL-8) se sugieren como potenciales biomarcadores salivales para la detección precoz del cáncer. La presente revisión bibliográfica evaluó la capacidad diagnóstica de la IL-6 e IL- 8 en el diagnóstico precoz de CCECO. Revisión: Los biomarcadores salivales constituyen un método sencillo, no invasivo y de bajo costo para la detección precoz de CCECO. Se pueden utilizar en todas las etapas del cáncer, desde etapas precancerosas hasta metástasis. Existen diversos tipos de biomarcadores, dentro del grupo de las citoquinas, la IL-6 e IL-8 son citoquinas proinflamatorias que favorecen la carcinogénesis al promover la proliferación, generación de radicales libres, la supervivencia celular y la angiogénesis. Su capacidad diagnóstica para la detección de CCECO se basa en que incrementan significativamente su concentración salival en presencia de la patología. Además poseen alta sensibilidad y especificidad para diagnosticar este cáncer. Conclusiones: Los biomarcadores salivales, IL-6 e IL-8, se consideran alternativas no invasivas de gran capacidad diagnóstica para el diagnóstico precoz de CCECO debido al incremento significativo de su concentración y altos valores de sensibilidad y especificidad (AU)


Introduction: Oral cancer is in the sixth place of the different types of cancer and more than 90% are oral squamous cell carcinoma (CCECO). Despite diagnostic and therapeutic advances, the survival rate is low due to late diagnosis. Alternative techniques have been described to replace the traditional biopsy and histopathology, including the use of salivary biomarkers. Interleukin-6 (IL-6) and interleukin-8 (IL-8) are suggested as potential salivary biomarkers for early cancer detection. This literature review evaluated the diagnostic capability of IL-6 and IL-8 in early diagnosis of CCECO. Review: Salivary biomarkers are simple, non-invasive and inexpensive for early detection of CCECO. They can be used in all stages of cancer from precancerous stages to metastasis. There are diverse types of biomarkers, within the group of cytokines the markers IL-6 and IL-8 are pro-inflammatory cytokines that facilitate carcinogenesis by promoting proliferation, generation of free radicals, cell survival and angiogenesis. Their diagnostic capability for the detection of CCECO is based on significant increases in their concentration in the presence of the pathology. They also have high sensitivity and specificity for diagnosing this cancer. Conclusions: As salivary biomarkers, IL-6 and IL-8, are considered as non-invasive alternatives of high diagnostic capability for early diagnosis of CCECO due to the significant increases in their concentration and high levels of sensitivity and specificity (AU)

RESUMO

BACKGROUND: Acute bronchiolitis comprises a major cause for morbidity in infants with viral infection which induces an immune inflammatory response that may produce long lasting harmful effects. Currently, there is no effective therapy for bronchiolitis. OBJECTIVE: Our aim was to investigate the efficacy of five-day montelukast therapy in acute bronchiolitis management. METHODS: The study included 50 infants with acute bronchiolitis. The infants with first episode of acute bronchiolitis were randomly assigned to receive daily montelukast dose of 4 mg over five days after admission or no treatment. Plasma eotaxin, IL-4, IL-8 and IFN-gamma levels were evaluated before and after treatment by ELISA method. In the present study, the primary outcome measure was change in clinical severity score, whilst secondary outcome measures were changes in plasma eotaxin, IL-4, IL-8, IFN-gamma levels. RESULTS: No significant differences was found in clinical severity score with five-day montelukast treatment (p > 0.05, Mann-Whitney U test). There were no significant differences in plasma eotaxin, IL-4, IL-8, IFN-gamma levels between the groups (p > 0.05 Mann-Whitney U test). There was significant decrease in plasma IFN-gamma levels following five-day montelukast treatment (p = 0.027, Wilcoxon). There were no significant differences in plasma IL-4, IL-8, IFN-gamma levels between the groups after five-day montelukast treatment (p > 0.05, Wilcoxon). There was significant increase in eotaxin levels after five-day montelukast treatment (p = 0.009, Wilcoxon). CONCLUSION: Our study showed that montelukast affected plasma IFN-gamma and eotaxin levels after five days of treatment. Further studies are needed to demonstrate effects of montelukast on chemokine levels in bronchiolitis

RESUMO

Purpose: It has been well established that high serum levels of interleukin-8 (IL-8) in ovarian cancer result in a poor clinical outcome. Thus, the aim of this study was investigating the role of IL-8 in ovarian cancer development. Methods: Two human ovarian cancer cell lines (SKOV3 and OVCAR3) were cocultured with IL-8 (100 ng/L) for 24 h, then cell migration was determined by transwell assay. Epithelial–mesenchymal transition (EMT)-associated proteins including E-cadherin and β-catenin, and phosphorylation status of β-catenin were investigated by Western blot analysis. Results: After treatment with IL-8 (100 ng/L) for 24 h, transwell assay result showed that the number of migrated ovarian cells increased significantly. Western blot analysis revealed that protein levels of E-cadherin were decreased, while that of β-catenin were elevated both in IL-8 pretreated SKOV3 and OVCAR3 cells. We further found that phosphorylation status of β-catenin were elevated either in cytoplasm or in nucleus of these two ovarian cancer cell lines after treatment with IL-8 for 24 h. Conclusions: Our data suggest that IL-8 induces EMT in ovarian cancer cells and implicates its potential role in enhancing ovarian cancer cell metastasis (AU)

RESUMO

Background and objective: Allergic airway diseases are not only a TH2-mediated chronic airway inflammation, but also a condition of epithelial barrier defects and dysfunction. Allergens with protease activities are known factors that initiate respiratory epithelial damage. Cockroach allergy is the second leading cause of allergic respiratory airway diseases in Taiwan, and cockroach allergens have strong serine protease activity. This study aimed to determine the protective effect of the direct local administration of gabexate mesilate (GM) on American cockroach allergen (CraA)-induced human bronchial epithelial cell inflammation. Methods: BEAS-2B cells, from the human bronchial epithelial cell line, were stimulated with CraA or co-cultured with different doses of GM. Cellular morphologic changes were observed by microscopy and changes in chemokine mRNA expression and protein levels were determined by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) and ELISA. Effects of specific inhibitors of ERK1/2 (U0126), JNK (SP600125), and p38 MAPK (SB203580) on CraA-induced chemokine mRNA expression were also tested by RT-PCR. Results: GM prevented CraA-induced bronchial epithelial cell detachment and morphological changes. It had superior and more extensive suppression effects than specific target MAPK inhibitors in CraA-induced mRNA expression of IL-8, monocyte chemotactic protein (MCP) 1, chemokine (C-C motif) ligand 20, and granulocyte-macrophage colony-stimulating factor from the cells in a dose-dependent manner. CraA-induced IL-8 and MCP-1 protein production from BEAS-2B cells was also attenuated by GM. Conclusions: The serine protease inhibitor GM has local protective effects against CraA-induced bronchial epithelial inflammation. The development of an inhaled or intranasal protease inhibitor may be a potential strategy for the treatment of allergic airway diseases induced by allergens with protease activities (AU)


Antecedentes y objetivo: Las enfermedades alergicas de las vias respiratorias no son solo fruto de una inflamacion cronica de las vias respiratorias mediada por Th2, sino que tambien se encuentran defectos fisicos y funcionales de la barrera epitelial. En este sentido, es conocido el papel de los alergenos con actividad proteasa que son los factores conocidos de inicio del dano epitelial respiratorio. La alergia a las cucarachas es la segunda causa principal de enfermedades alergicas de las vias respiratorias en Taiwan y estos alergenos poseen una potente actividad serin-proteasa. Este estudio tuvo como objetivo determinar el efecto protector del mesilato de gabexate (GM) contra la inflamacion inducida por la administracion local directa de alergenos de la cucaracha americana (CRAA), sobre las celulas epiteliales bronquiales humanas. Metodos: Se empleo la linea de celulas epiteliales bronquiales, celulas BEAS-2B, las cuales se estimularon con CRAA o fueron co-cultivadas con diferentes dosis de GM. Se analizaron los cambios morfologicos celulares por microscopia y los cambios en la expresion de ARNm de diferentes quimiocinas, asi como los niveles de proteina. Se utilizaron metodos semi-cuantitativos de RT-PCR y ELISA. Los efectos de inhibidores especificos de ERK1/2 (U0126), JNK (SP600125), y p38 MAPK (SB203580) en las expresion de ARNm de quimiocinas inducidas por CRAA, tambien se ensayaron por RT-PCR. Resultados: El mesilato de gabexate impidio el desprendimiento de las celulas epiteliales y los cambios morfologicos inducidos con CRAA a nivel bronquial. Sus efectos supresores fueron mas potentes y prolongados que los obtenidos con inhibidores especificos de MAPK sobre la expresion del ARNm de IL-8, MCP-1, CCL20 y GMSF en una forma dosis-dependiente. La produccion proteica de IL-8 y MCP-1 de las celulas BEAS-2B tambien fue menor cuando se anadio GM. Conclusiones: El mesilato de gabexate, inhibidor serin-proteasa , tiene efectos protectores locales contra la inflamacion bronquial epitelial inducida por la cucaracha americana. El desarrollo de un inhibidor de la proteasa, por via inhalada o intranasal, puede ser una estrategia potencial para el tratamiento de enfermedades de las vias respiratorias alergicas inducidas por alergenos con actividad proteasa (AU)

RESUMO

OBJETIVO: investigar si los pacientes con ETV presentan diferencias en la cuantificación de marcadores inflamatorios de disfunción endotelial (IL-6 y IL8) en fase estable. MATERIAL Y MÉTODOS: pacientes con ETV aguda sintomática de cualquier causa en los que, a los 3 meses de seguimiento, se les realizó una determinación de IL-6 e IL-8. Los pacien tes con ETV los dividimos en 3 grupos según la etiología del evento: 1) ETV idiopático. 2) ETV 2º a cáncer. 3) ETV 2º a otra causa. RESULTADOS: la muestra fue de 77 pacientes. La distribución de los pacientes según la etiología de la ETV fue la siguiente: ETV idiopático (n=40). ETV 2º a cáncer (n=26). ETV 2º a otra etiología (n=11). La mediana de IL-6 para cada uno de los grupos fue: ETV idiopática 2,96 pg/ml, ETV secundaria a cáncer 3,87 pg/ml y ETV secundaria a otra etiología 2,30 pg/ml. La mediana de IL-8 para cada uno de los grupos fue de 0,00 pg/ml. Cuando comparamos las dos determinaciones en los 3 grupos según la etiología del evento: 1) ETV idiopático. 2) ETV 2º a cáncer. 3) ETV 2º a otra causa. RESULTADOS: la muestra fue de 77 pacientes. La distribución de los pacientes según la etiología de la ETV fue la siguiente: ETV idiopático (n=40). ETV 2º a cáncer (n=26). ETV 2º a otra etiología (n=11). La mediana de IL-6 para cada uno de los grupos fue: ETV idiopática 2,96 pg/ml, ETV secundaria a cáncer 3,87 pg/ml y ETV secundaria a otra etiología 2,30 pg/ml. La mediana de IL-8 para cada uno de los grupos fue de 0,00 pg/ml. Cuando comparamos las dos determinaciones en los 3 grupos obser-vamos como no hay diferencias significativas entre ellos, aun-que existía cierta tendencia a la significación estadística en la determinación de IL-6 (p = 0,054). CONCLUSIONES: los marcadores inflamatorios de disfunción endotelial (IL-6 y IL8) no mostraron diferencias significativas en los tres grupos, aunque un incremento de la muestra podría evidenciar diferencias de la IL-6 entre los tres grupos. A los tres meses de tratamiento los niveles medios de IL-8 son inde-tectables en los 3 grupos


OBJECTIVE: to investigate whether patients with VTD present differences in the quantification of endothelial dys-function inflammatory markers (IL-6 and IL8) during the stable phase. MATERIAL AND METHODS: patients with symptomatic acute VTD of any cause and who, at the 3 months follow-up, had determina-tion for IL-6 and IL-8 performed. The patients with VTD were divided into three groups according to the etiology of the event: 1) idiopathic VTD, 2) VTD secondary to cancer, 3) VTD secondary to another cause. RESULTS: there were 77 patients in the sample. The distribution of the patients according to the etiology of the VTD was as fo-llowing: idiopathic VTD (n=40). VTD secondary to cancer (n=26). VTD secondary to another cause (n=11). The median of IL-6 for each one of the groups was: idiopathic VTD 2.96 pg/ml. VTD secondary to cancer 3.87 pg/ml. VTD secondary to another cause 2.30 pg/ml. The median of IL-8 for each one of the groups at three months was 0.00 pg/ml. When we compared the two determinations in the three groups, we observed that there were no significant differences between them, although there was a certain tenden-cy towards statistical significance in the determination of IL-6 (p = 0.054). CONCLUSIONS: the endothelial dysfunction inflammatory markers (IL-6 and IL8) did not show significant differences in the three groups, although an increase in the size of the sample could lead to differences being found in the IL-6 between the three groups. After three months of treatment, the median levels of IL-8 are indetectables in the three groups

RESUMO

Objetivo: Comparar las concentraciones de IL-8 en pacientes con preeclampsia y embarazadas normotensas sanas. Material y métodos Se seleccionó un total de 100 pacientes. Se incluyeron a 50 pacientes preeclámpticas como los casos (grupo A) y un grupo control que fue seleccionado por tener una edad y un índice de masa corporal similares al grupo de estudio, y consistió en 50 embarazadas sanas (grupo B). Las muestras de sangre para la determinación de IL-8 se recolectaron en todas las pacientes antes del parto e inmediatamente después del diagnóstico en el grupo de casos. Resultados No se encontraron diferencias significativas con relación a la edad materna, edad gestacional e índice de masa corporal al momento de la toma de la muestra (p=ns). Se observaron diferencias estadísticamente significativas entre los grupos en los valores promedio de presión arterial sistólica y diastólica (p<0,05). Las concentraciones de IL-8 fueron significativamente superiores en el grupo A (54,8±13,6pg/ml) comparado con el grupo B (33,6±6,3pg/ml, p<0,05) y se observó una correlación fuerte, positiva y significativa con los valores de presión arterial sistólica (r=0,715; p<0,05) y con los valores de presión arterial diastólica (r=0,640; p<0,05).Conclusión Las pacientes preeclámpticas presentaron concentraciones significativamente más altas de concentraciones de IL-8 al compararlo con embarazadas normotensas sanas (AU)


Objective: To compare concentrations of interleukin-8 in patients with preeclampsia and healthy normotensive pregnant women. Material and methods: One hundred patients were selected. Fifty preeclamptic patients were selected as cases (group A) and 50 healthy pregnant women with a similar age and body massindex to patients in group A were selected as controls (group B). Blood samples for interleukin-8were collected in all patients before labor and immediately after diagnosis in the study group. Results: There were no significant differences in maternal age, gestational age or body massindex at sample collection (p=ns). Statistically significant differences were found between groups in mean values of systolic and diastolic blood pressure (p<0.05). Interleukin-8 concentrations were significantly higher in group A (54.8±13.6 pg/ml) than in group B (33.6±6.3 pg/ml,p<0.05) and there was a strong, positive and significant correlation with values of systolic blood pressure (r=0.715; p<0.05) and diastolic blood pressure (r=0.640; p<0.05).Conclusion: Interleukin-8 concentrations were significantly higher in preeclamptic patients than in healthy normotensive pregnant women (AU)

RESUMO

Objetivos: El presente estudio evalúa la utilidad pronóstica que la determinación seriada de diferentes biomarcadores (procalcitonina [PCT], proteína C reactiva [PCR] y leucocitos) podría tener en los enfermos en shock séptico. Diseño: Estudio prospectivo observacional. Ámbito: La unidad de cuidados intensivos (UCI) de nuestro centro, un Hospital Universitario de tercer nivel. Pacientes: Ochenta y ocho pacientes en shock séptico según criterios de la Conferencia de Consenso SCCM/ESICM/ACCP/ATS/SIS de 2001. Se llevó a cabo la determinación de PCT, PCR y leucocitos al ingreso en la UCI y a las 72 horas del mismo. Intervenciones: Ninguna. Resultados: Los pacientes con incremento en los valores de PCT presentaron una mayor mortalidad hospitalaria en comparación con los que presentaron un descenso de los mismos (58,8 frente al 15,4%, p<0,01). Este efecto no se observó en las determinaciones de PCR ni los leucocitos. El mejor área bajo la curva ROC para el pronóstico correspondió al aclaramiento de PCT (0,79). El aclaramiento del 70% en los valores de PCT permitió discriminar la supervivencia hospitalaria con una sensibilidad del 94,7% y una especificidad del 53%. Conclusiones: La determinación seriada de los valores de PCT predice mejor que la determinación única el pronóstico de los pacientes en shock séptico. Su fiabilidad pronóstica es superior a la de la PCR y los leucocitos. El uso de las determinaciones seriadas de PCT podría ayudar a identificar a aquellos pacientes sépticos con mayor riesgo de muerte permitiendo optimizar su tratamiento (AU)


Objetives: This study evaluates the potential prognostic value of serial measurements of different biomarkers (procalcitonin [PCT], C-reactive protein and leukocytes [CRP]) in septic shock patients. Design: Prospective observational study. Setting: Intensive care unit of a third-level University Hospital. Patients: The study comprised a total of 88 septic shock patients defined using the 2001 Consensus Conference SCCM/ESICM/ACCP/ATS/SIS criteria. The PCT, CRP and leukocytes were recorded on admission to the ICU and again 72hours after admission. Interventions: None. Results: Those patients with increasing procalcitonin levels showed higher hospital mortality than those with a decreasing levels (58.8% vs. 15.4%, P<0.01). No such effect was observed in relation to C-reactive protein or leukocytes. The best area under the curve for prognosis was for procalcitonin clearance (0.79). A procalcitonin clearance of 70% or higher offered a sensitivity and specificity of 94.7% and 53%, respectively. Conclusions: Serial procalcitonin measurements are more predictive of the prognosis of septic shock patients than single measurements of this parameter. The prognostic reliability of the latter is also better than in the case of C-reactive protein and leukocytes. The application of serial procalcitonin measurements may allow the identification of those septic patients at increased mortality risk, and help improve their treatment (AU)

RESUMO

En el diagnóstico del reflujo vésico-ureteral se emplean métodos de imagen invasivos que requieren sondajes. Nuestro objetivo es evaluarla utilidad de los niveles urinarios de interleuquinas en el diagnóstico del reflujo en niños sin infección urinaria en curso. Métodos. Estudio de casos y controles en niños que acuden a realizar una cistouretrografía miccional (CUMS): 40 casos con reflujo y80 controles. Se determinó en todos la concentración en orina de IL-1,IL-6 e IL-8 en relación con la creatinina. Resultados. 62 niños y 58 niñas, con 2,4 años de edad media. La CUMS se indicó por infección urinaria previa en 78 (65%), hallazgos prenatales en 24 (20%) y diagnóstico postnatal de uropatía o historia familiar en 18 (15,1%). No se han observado diferencias significativas en los niveles urinarios de IL-1/creatinina e IL-6/creatinina entre ambos grupos; sin embargo, los niveles de IL-8/creatinina fueron significativamente más altos en los casos (media 3,5 pg/μmol; SD 9,2) que en los controles (media 1,54 pg/μmol; SD 3) (p=0,001). La odds ratio fue de5,57 (IC 95%: 1,51 a 20,60) (XMH=2,80; p=0,005).Conclusiones. Los niveles urinarios de IL-8/creatinina están elevados en niños con reflujo, incluso en ausencia de infección. Estos podrían utilizarse como biomarcador no invasivo para la detección de los casos subclínicos de enfermedad (AU)


Invasive imaging methods that require catheterization are used for the diagnosis of vesicoureteral refl ux. Our aim is to assess the usefulness of interleukin urinary levels for the diagnosis of reflux in children without urinary tract infection. Methods. Case-control study in children who underwent a voiding cystourethrogram: forty cases diagnosed of refl ux and 80 controls. Concentrations of IL-1, IL-6 and IL-8 related to creatinine levels (pg/μmol) were determined in urine samples in all. Results. Sixty-two patients were males and fi fty-eight females, with a mean age of 2.4 years. Indications for cystography were previousurinary tract infection in 78 cases (65%), prenatal diagnosis in 24 cases(20%) and postnatal diagnosis of uropathy or family history in 18 cases(15.1%). No significant differences were observed between cases and controls in IL-1/creatinine and IL-6/creatinine levels. However, IL-8/creatinine levels were almost significant higher in case group (median3.5 pg/μmol; SD 9.2) than in control group (median 1.54 pg/μmol; SD 3)(P=0.001). The odds ratio was 5.57 (CI 95%: 1.51 a 20.60) (XMH=2.80;p=0.005).Conclusions. Urinary levels of IL-8/creatinine are elevated in children with vesicoureteral reflux, even in absence of urinary tractinfection. It could be used as a non-invasive marker for detection of subclinical cases of disease (AU)

RESUMO

Introducción: El humo de tabaco es la principal causa de la inflamación en la EPOC. Los mecanismos quediferencian a los fumadores que desarrollan EPOC son diversos. En este estudio analizamos la diferentepresencia de citocinas en secreciones respiratorias de pacientes fumadores con o sin EPOC y las propiedadessecretoras del epitelio bronquial diferenciado, obtenido de los propios individuos tras su exposiciónal humo de tabaco.Material y métodos: Se estudió a 27 pacientes fumadores, 12 de ellos con EPOC no tratados previamentecon esteroides. En 11 se obtuvo la muestra mediante esputo inducido y el resto procedía del aspiradobronquial tras fibrobroncoscopia. Se determinaron las concentraciones de IL8, IL13 y TNF en el sobrenadante.Se compararon los resultados obtenidos entre individuos con o sin EPOC y se investigó su relacióncon la gravedad de la EPOC expresada según el grado de obstrucción, disnea, presencia de hipersecrecióne intensidad del tabaquismo. Se obtuvieron cultivos de células diferenciadas epiteliales bronquiales,mediante interfase aire-líquido en 4 individuos fumadores. Las muestras fueron expuestas a concentracionescrecientes de humo de tabaco (5-20%) y se determinó la expresión epitelial de ARNm de Muc5AC,IL8 y TNF .Resultados: Los pacientes con EPOC tenían valores significativamente más altos de IL8 que los fumadoressanos (41 [22] vs. 21 [12] pM). Los valores de IL8 se correlacionaron de forma significativa con la gravedadde la obstrucción (r = 0,6; p < 0,05), disnea (r = 0,45; p < 0,05) y la presencia de hipersecreción. No habíarelación entre las citocinas y la intensidad o duración del hábito tabáquico. El humo de tabaco produjoun incremento dependiente de la dosis en la expresión de ARNm para Muc5AC, IL8 y TNF. Conclusiones: Existen diferencias en la producción de citocinas, fundamentalmente IL8, entre individuosfumadores sanos o con EPOC que podrían ser justificadas por la acción directa del humo de tabaco sobrelas células epiteliales (AU)


Introduction: Cigarette smoke is the main cause of inflammation in COPD. The mechanisms that differentiatesmokers who develop COPD are diverse. In this study, we analyzed the presence of cytokines in therespiratory secretions of smokers with or without COPD and the secretory properties of the differentiatedbronchial epithelium obtained from the individuals themselves after exposure to tobacco smoke.Material and methods: Twenty-seven smokers were studied, 12 of whom had COPD that had not beenpreviously treated with steroids. In 11, samples were obtained by means of induced sputum, and the remaining samples were collected from bronchial aspiration after bronchoscopy. Concentrations of IL-8,IL-13 and TNF in the supernatant were determined. The results obtained were compared between individualswith and without COPD, and we studied their relationship with the severity of COPD as expressedby the degree of obstruction, dyspnea, presence of hypersecretion and intensity of smoking. Bronchialepithelial cell cultures were obtained by air-liquid interface in 4 smokers. The samples were exposed toincreasing concentrations of cigarette smoke (5-20%) and the epithelial mRNA expressions of MUC5AC,IL8 and TNF were determined.Results: COPDpatients had significantly higher values of IL-8 than healthy smokers (41 [22] vs. 21 [12] pM).The values of IL-8 correlated significantly with the severity of the obstruction (r = 0.6; p < 0.05), dyspnea(r = 0.45; p < 0.05) and the presence of hypersecretion. There was no relationship between cytokines andthe intensity or duration of the tobacco habit. Cigarette smoke produced a dose-dependent increase inthe expression of RNAm for Muc5AC, IL8 and TNF .Conclusions: There are differences in cytokine production (fundamentally IL8) between smokers and smokerswith COPD which could be explained by the direct action of cigarette smoke on epithelial cells (AU)
