ABSTRACT

MRI is the cornerstone in the evaluation of brain metastases. The clinical challenges lie in discriminating metastases from mimickers such as infections or primary tumors and in evaluating the response to treatment. The latter sometimes leads to growth, which must be framed as pseudo-progression or radionecrosis, both inflammatory phenomena attributable to treatment, or be considered as recurrence. To meet these needs, imaging techniques are the subject of constant research. However, an exponential growth after radiotherapy must be interpreted with caution, even in the presence of results suspicious of tumor progression by advanced techniques, because it may be due to inflammatory changes. The aim of this paper is to familiarize the reader with inflammatory phenomena of brain metastases treated with radiotherapy and to describe two related radiological signs: "the inflammatory cloud" and "incomplete ring enhancement", in order to adopt a conservative management with close follow-up.

ABSTRACT

La resonancia magnética es la piedra angular en la evaluación de las metástasis cerebrales. Los retos clínicos residen en discriminar las metástasis de imitadores como infecciones o tumores primarios y en evaluar la respuesta al tratamiento. Este, en ocasiones, condiciona un crecimiento, que debe encuadrarse como una pseudoprogresión o una radionecrosis, ambos fenómenos inflamatorios atribuibles al mismo, o bien considerarse como una recurrencia. Para responder a estas necesidades, las técnicas de imagen son objeto de constantes investigaciones. No obstante, un crecimiento exponencial tras la radioterapia debe interpretarse con cautela, incluso ante resultados sospechosos de progresión por técnicas avanzadas, ya que puede tratarse de una radionecrosis. El objetivo de este trabajo es familiarizar al lector con los fenómenos inflamatorios de las metástasis cerebrales tratadas con radioterapia y describir dos signos radiológicos relacionados: la «nube inflamatoria» y el «realce en anillo incompleto», con el fin de adoptar un manejo conservador en estos casos.(AU)

ABSTRACT

OBJECTIVE: This study investigated the relationship of the pre-operative neutrophil/lymphocyte ratio (NLR) to the timing of epidural analgesia administration and post-operative acute and chronic pain in thoracotomy. MATERIALS AND METHODS: The study was conducted on 60 patients, with NLR ≥ 2 (Group A) and NLR < 2 (Group B). Each group was divided into subgroups pre-emptive analgesia (Group P) and control group (Group C). Epidural analgesic solution was administered as a bolus before the surgical incision in Group P and at the end of the operation in Group C. NRS was questioned postoperatively at the 2nd, 4th, 8th, 12th, 24th h, 1st, and 3rd months and also additional analgesic needs were recorded. RESULTS: In Group A, the pain scores of the patients who received pre-emptive epidural analgesia were lower at the post-operative 2nd, 4th, and 8th h and analgesic consumption was less in the post-operative first 24 h. CONCLUSION: It was observed that pre-emptive epidural analgesia reduced pain levels and additional analgesic consumption in the acute post-operative period in patients with pre-operative NLR ≥ 2.


OBJETIVO: Este estudio investigó la relación de la relación neutrófilos/linfocitos (NLR) preoperatoria con el momento de la administración de la analgesia epidural y el dolor agudo y crónico posoperatorio en la toracotomía. MATERIALES Y MÉTODOS: El estudio se realizó en 60 pacientes, como NLR ≥ 2 (Grupo A) y NLR < 2 (Grupo B). Cada grupo se dividió en subgrupos de analgesia preventiva (Grupo P) y grupo control (Grupo C). La solución analgésica epidural se administró en bolo antes de la incisión quirúrgica en el Grupo P y al final de la operación en el Grupo C. La NRS se cuestionó posoperatoriamente a las 2, 4, 8, 12, 24 horas, 1 y 3 meses también adicionales Se registraron las necesidades analgésicas. RESULTADOS: En el Grupo A, los puntajes de dolor de los pacientes que recibieron analgesia epidural preventiva fueron menores a las 2, 4 y 8 horas postoperatorias y el consumo de analgésicos fue menor en las primeras 24 horas postoperatorias. CONCLUSIÓN: Se observó que la analgesia epidural preventiva redujo los niveles de dolor y el consumo adicional de analgésicos en el postoperatorio agudo en pacientes con NLR preoperatorio ≥ 2.

ABSTRACT

Objective: To evaluate the prognostic performance of the neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) for mortality in patients with acute stroke treated at a Peruvian hospital. Design: Retrospective cohort study. Setting: Tertiary care hospital. Patients: Patients aged ≥18 years with a diagnosis of acute stroke and admitted to the hospital from May 2019 to June 2021. Interventions: None. Main variables of interests: Neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and mortality. Results: A total of 165 patients were included. The mean age was 66.1±14.2 years, and 59.4% were male. Only NLR had a performance superior to 0.7 (AUC: 0.75; 95%CI: 0.65–0.85), and its elevated levels were associated with an increased risk of mortality (aRR: 3.66; 95%CI: 1.77–8.85) after adjusting for confounders. Conclusion: The neutrophil-to-lymphocyte ratio has an acceptable prognostic performance for mortality in patients with acute stroke. Its use may be considered to stratify patients’ risk and to consider timely alternative care and management.(AU)

ABSTRACT

Objetivo Determinar la utilidad de los cocientes neutrófilos/linfocitos (N/L) y plaquetas/linfocitos (P/L), así como de parámetros cuantitativos de la PET/TC con [18F]FDG, como factores pronósticos para la supervivencia global (SG), la supervivencia cáncer específica (SCE) y la supervivencia libre de progresión (SLP) en pacientes con carcinoma escamoso de cabeza y cuello (CyC) Material y métodos Se valoraron retrospectivamente 66 pacientes (56 hombres) diagnosticados de CyC durante un intervalo de 8años. Se determinaron los parámetros SUV máximo (SUVmax), volumen metabólico tumoral (MTV) y glucólisis tumoral total (TLG) del estudio PET/TC al diagnóstico. Tras tratamiento con quimiorradioterapia, se valoró la supervivencia de los pacientes. El modelo de regresión de Cox y el método de Kaplan-Meier se utilizaron para analizar factores pronósticos y curvas de supervivencia. Resultados El seguimiento medio fue de 50,4meses, produciéndose 39 recurrencias-progresiones y 39 fallecimientos. En el análisis univariante los parámetros metabólicos, excepto el SUVmax, fueron factores predictivos para las tres supervivencias, y los dos parámetros sanguíneos lo fueron para la SG y la SCE. La TLG fue el único factor predictivo en el análisis multivariante. Las tres curvas de supervivencias fueron significativamente diferentes para los parámetros metabólicos y la curva de SG para el cociente N/L. Se apreciaron correlaciones entre el cociente N/L, el MTV y la TLG. No se demostraron correlaciones entre el cociente P/L y los parámetros metabólicos. Conclusión El uso de marcadores hematológicos y metabólicos permitiría identificar pacientes con un alto riesgo de recurrencias y pobre supervivencia e individualizar el tratamiento aplicando terapias más agresivas (AU)


Aim To determine the usefulness of neutrophil/lymphocyte (N/L) and platelet/lymphocyte (P/L) ratios as well as quantitative [18F]FDG PET/CT parameters as prognostic factors for overall survival (OS), cancer-specific survival (CSS) and progression-free survival (PFS) in patients with head and neck squamous cell carcinoma (HyN). Material and methods Sixty-six patients (56 men) diagnosed with HyN carcinoma were retrospectively assessed over an 8-year interval. Maximum SUV (SUVmax), metabolic tumour volume (MTV) and total lesion glycolysis (TLG) parameters were determined from the PET/CT study at diagnosis. After treatment with chemoradiotherapy, patient survival was assessed. The Cox regression model and the Kaplan-Meier method were used to analyse prognostic factors and survival curves. Results Median follow-up was 50.4months, with 39 recurrences-progressions and 39 deaths. In the univariate analysis, metabolic parameters, except SUVmax, were predictive factors for all three survivals and the two blood parameters were predictive for OS and EFS. TLG was the only predictive factor in the multivariate analysis. The three survival curves were significantly different for the metabolic parameters and the OS curve for the N/L ratio. Correlations were seen between N/L ratio, MTV and TLG. No correlations were demonstrated between P/L ratio and metabolic parameters. Conclusion The use of haematological and metabolic markers would allow to identify patients with a high risk of recurrences and poor survival and to individualise treatment by applying more aggressive therapies (AU)

ABSTRACT

OBJETIVOS: comparar entre el índice de linfocitos neutrófilos (NLR) y el volume plaquetario medio (VPM) en la predicción de la viscosidad del derrame en otitis media con derrame. MATERIALES Y MéTODOS: Se incluyeron en el estudio 248 niños con derrame en el oído medio. Se evaluaron hemogramas completos (CBC) preoperatorios. Se registraron los valores de NLR y MPV. La viscosidad del derrame se evaluó durante la cirugía mientras se aspiraba el derrame después de la miringotomía. De esta forma se clasificaron 2 tipos de derrames; tipos serosos y mucoides. RESULTADOS: se reportaron diferencias estadísticamente significativas en NLR y MPV entre los tipos serosos y mucoides. Los valores de corte de NLR y MPV para diferenciar entre derrames serosos y mucoides fueron 1,21 y 7,95 respectivamente. Cuando se compararon NLR y MPV, NLR pareció tener mayor sensibilidad, especificidad y precisión que MPV. CONCLUSIóN: NLR es superior a MPV como predictor de la viscosidad del derrame en otitis media con derrame. Ambos marcadores se consideran rentables y fiables para la evaluación de la viscosidad del derrame.

ABSTRACT

ABSTRACT Objective: To examine the neutrophil-lymphocyte ratio, red cell distribution width and mean platelet volume in patients with febrile seizure and to determine their role in febrile seizure classification. Methods: This was a retrospective hospital-based study conducted among patients aged 5 to 72 months admitted with febrile seizure. Children who had febrile seizures due to upper respiratory tract infection were included in the study. The children were divided into two groups: simple febrile seizures and complex febrile seizures. Patients with a history of febrile status epilepticus, previous convulsions, use of antiepileptic or other chronic drugs, foci of infection other than the upper respiratory tract infection, abnormal biochemical parameters, and chronic mental or physical disease were excluded from the study. Clinical and laboratory findings of the patients were obtained from digital medical records. Results: The records of 112 febrile seizure patients were reviewed, and 89 were grouped as simple and 23 as complex febrile seizures. Although there was no statistically significant difference between the two groups in terms of the mean red cell distribution width values (p=0.703), neutrophil-lymphocyte ratio and mean platelet volume were significantly higher in patients with complex febrile seizures (p=0.034, p=0.037; respectively). Conclusions: This study showed that neutrophil-lymphocyte ratio and mean platelet volume could be practical and inexpensive clinical markers for febrile seizure classification. A similar result could not be reached for red cell distribution width in this study. These findings should be supported by multicenter studies with large samples.


RESUMO Objetivo: Examinar a relação linfócitos-neutrófilos, amplitude de distribuição de hemácias e volume médio de plaquetas em pacientes com convulsão febril, e determinar seu papel na classificação de convulsão febril. Métodos: Este foi um estudo retrospectivo de base hospitalar realizado com pacientes de 5 a 72 meses admitidos com convulsão febril. Crianças que tiveram convulsões febris em razão de infecção do trato respiratório superior foram incluídas no estudo. As crianças foram divididas em dois grupos: convulsões febris simples e complexas. Pacientes com história de Status epiléptico febril, convulsões prévias, uso de drogas antiepilépticas ou outras drogas crônicas, com focos de infecção que não a do trato respiratório superior, parâmetros bioquímicos anormais e doenças crônicas mentais ou físicas foram excluídos do estudo. Os achados clínicos e laboratoriais dos pacientes foram obtidos a partir dos prontuários médicos digitais. Resultados: Registros de 112 pacientes com convulsão febril foram revisados: 89 com convulsões febris simples e 23 com complexas. Embora não tenha havido diferença estatisticamente significativa entre os dois grupos em termos de valor médio de amplitude de distribuição de hemácias (p=0,703), a relação linfócitos-neutrófilos e o volume médio de plaquetas foram significativamente mais elevados em pacientes com convulsões febris simples (p=0,034, p=0,037; respectivamente). Conclusões: Este estudo mostrou que a relação linfócitos-neutrófilos e o volume médio de plaquetas podem ser marcadores clínicos práticos e de baixo custo para a classificação de convulsão febril. Um resultado semelhante não pôde ser alcançado para a amplitude de distribuição de hemácias neste estudo. Esses achados devem ser apoiados por estudos multicêntricos com grandes amostras.

ABSTRACT

Introducción: la inmunosenescencia está asociada con un mayor riesgo de desarrollo de cáncer. Dentro de las hemopatías malignas que afectan a este grupo de edad, está la leucemia linfoide crónica (LLC), caracterizada por trastornos en la inmunidad adaptativa que incluye las subpoblaciones de linfocitos T. Objetivo: Determinar la frecuencia de las subpoblaciones de linfocitos T en los pacientes adultos mayores con leucemia linfoide crónica evaluados en el Instituto de Hematología e Inmunología de Cuba. Métodos: Se realizó un estudio transversal en 30 adultos mayores con leucemia linfoide crónica. Se cuantificaron los linfocitos TCD3+CD4+ y TCD3+CD8+ en sangre periférica por citometría de flujo. Para la lectura y el análisis de los datos se empleó un citómetro de flujo Beckman Coulter Gallios. Se utilizaron los valores porcentuales, la media y la desviación estándar. Se consideró estadísticamente significativo si p≤0.05. Resultados: Hubo un predominio de hombres que representaron el 56,7 por ciento y del grupo de 70-79 años de edad. No se reportó ningún adulto mayor con LLC con valores altos ni normales de linfocitos TCD3+CD4+. Predominaron los hombres con valores bajos porcentuales de linfocitos TCD3+CD4+, TCD3+CD8+ e inversión del índice CD4/CD8 en relación con las mujeres. Conclusiones: Los adultos mayores con LLC presentan alteraciones en el número de las subpoblaciones de linfocitos T. La acción de estas células en relación al crecimiento de células B malignas aún es desconocido y resulta importante determinar si esto puede reflejar un intento de evasión de las células tumorales al control inmunológico(AU)


Introduction: Immunosenescence is associated with an increased risk of cancer development. Among the malignant hemopathies that affect this age group, it is chronic lymphoid leukemia (CLL), characterized by disorders in adaptive immunity, which include subpopulations of T lymphocytes. Objective: To determine frequency of T lymphocyte subpopulations in older adult patients with chronic lymphoid leukemia evaluated at the Institute of Hematology and Immunology of Cuba. Methods: A cross-sectional study was conducted in 30 older adults with chronic lymphoid leukemia. TCD3+CD4+ and TCD3+CD8+ lymphocytes were quantified in peripheral blood by flow cytometry. A Beckman Coulter Gallios flow cytometer was used to read and analyze the data. The percentage values, the mean and the standard deviation were used. It was considered statistically significant if p≤0.05. Results: There was a predominance of men who represented 56.7 percent and the age group of 70-79 years. No older adults with CLL with high or normal values of TCD3+CD4+ lymphocytes were reported. Men predominated with low percentage values of TCD3+CD4+, TCD3+CD8+ lymphocytes and inversion of the CD4/CD8 ratio in relation to women. Conclusions: Older adult with CLL present alterations in the number of T lymphocyte subpopulations. The role of these cells in relation to the growth of malignant B cells it is unknown and it turns out important to determine if this may reflect an attempt to evade tumor cells from immune control(AU)

ABSTRACT

OBJECTIVE: Lymphocyte-to-monocyte ratio (LMR) has been introduced as a predictor and a prognostic factor for multiple diseases. This study aimed to determine the efficiency of LMR in predicting the recurrence of spontaneous pneumothorax. MATERIALS AND METHODS: A total of 374 patients who had received chest tubes at the first episode of primary spontaneous pneumothorax were examined in terms of age, gender, side of the pneumothorax, status of recurrence, LMRs at the time of admittance and recurrence, and the interval until the recurrence. RESULTS: Recurrence was diagnosed in 106 (28.3%) patients, whereas the mean time until the recurrence was 15.32 ± 5.57 months. Significantly, the recurrence rate was higher, while the time until the relapse was shorter for patients with elevated levels of LMR. Moreover, LMR counting over 1.25 demonstrated a 70.8% sensitivity and a 94.4% specificity in predicting a potential recurrence. CONCLUSIONS: Calculation of LMR at the first episode of spontaneous pneumothorax contributes to predict a potential recurrence when combined with traditional risk factors.


OBJETIVOS: La proporción de linfocitos a monocitos (PLM) se ha introducido como un predictor y un factor pronóstico para múltiples enfermedades. Este estudio tuvo como objetivo determinar la eficiencia de LMR en la predicción de la recurrencia del neumotórax espontáneo. MATERIALES Y MÉTODOS: Un total de 374 pacientes que habían recibido tubos de tórax en el primer episodio de neumotórax espontáneo primario fueron examinados en términos de edad, género, lado del neumotórax, estado de recurrencia, PLM al momento del ingreso y recurrencia, y el intervalo hasta la recurrencia. RESULTADOS: Se diagnosticó recidiva en 106 (28.3%) pacientes, siendo el tiempo medio hasta la recidiva de 15.32 ± 5.57 meses. Significativamente, la tasa de recurrencia fue mayor, mientras que el tiempo hasta la recaída fue más corto para los pacientes con niveles elevados de PLM. Además, el recuento de PLM superior a 1.25 demostró una sensibilidad del 70.8 % y una especificidad del 94.4 % para predecir una posible recurrencia. CONCLUSIÓN: Calcular la PLM en el primer episodio de neumotórax espontáneo predice una posible recurrencia cuando se combina con los factores de riesgo tradicionales.

ABSTRACT

Background: Critically ill newborns (NB) are susceptible to serious complications due to their immature immune system. Objective: To know the prognostic utility of inflammatory indexes in critically ill NBs. Material and methods: Observational, analytical, longitudinal, prospective study. We included NBs hospitalized, critically ill and non-critically ill, who had a complete blood count at 12 hours of life (initial) and within 24 hours prior to discharge due to improvement or death (final). Systemic immune-inflammatory Index (SII), Neutrophil/Lymphocyte Ratio (NLR) and Platelets/Lymphocyte Ratio (PLR) were analyzed. There was follow-up from birth to discharge. Results: 211 patients of 33 (32-34) weeks of gestation, weight 1.569 (1.480-1.720) kg. 106 critical NB and 105 non-critical NB, with 50 deaths in the former group, were analyzed. The final NLR ≥ 1.38 (sensitivity [S] 58%, specificity [Sp] 58%, AUC 0.60 [p 0.006]) identified critically ill NBs compared to non-critical ill NBs; final NLR ≥ 1.84 (S 71%, Sp 71%, AUC 0.79 [p < 0.0001]) identified critically ill NBs who died compared to all those who survived; final SII ≥ 255.411 x 103 (S 55%, Sp 56%, AUC 0.60 [p 0.047]) and final NLR ≥ 1.75 (S 76%, Sp 76%, AUC 0.84 [p < 0.0001]) identified critical NBs who died from those who survived. Conclusion: The final NLR predicts which NBs may perish with respect to all who survive. The final NLR and SII predict among critically ill NBs who may die.


Introducción: los recién nacidos (RN) críticamente enfermos son susceptibles de mal pronóstico debido a su sistema inmunitario inmaduro. Objetivo: conocer la utilidad pronóstica de los índices inflamatorios en RN críticamente enfermos. Material y métodos: estudio observacional, analítico, longitudinal, prospectivo. Incluimos RN hospitalizados, críticamente enfermos y no críticos, que contaran con biometría hemática completa a las 12 horas de vida (inicial) y dentro de las 24 horas previas al egreso por mejoría o defunción (final). Se analizó el Índice inmunosistémico (IIS), neutrófilos linfocitos (INL) y plaquetas linfocitos (IPL). Hubo seguimiento desde el nacimiento hasta el egreso. Resultados: se analizaron 211 pacientes, de 33 (32-34) semanas de gestación, peso 1.569 (1.480-1.720) kg; 106 RN críticos y 105 no críticos, con 50 defunciones en los primeros. El INL final ≥ 1.38 (sensibilidad [S] 58%, especificidad [E] 58%, ABC 0.60 [p 0.006]) identificó RN críticamente enfermos con respecto a RN no críticos; INL final ≥1.84 (S 71%, E 71%, ABC 0.79 [p < 0.0001]) identificó RN críticamente enfermos que fallecieron con respecto a todos los que sobrevivieron; el IIS final ≥ 255.411 x 103 (S 55%, E 56%, ABC 0.60 [p 0.047]) e INL final ≥ 1.75 (S 76%, E 76%, ABC 0.84 [p < 0.0001]) identificaron a RN críticamente enfermos que fallecieron con respecto a los que sobrevivieron. Conclusiones: el INL final predice que RN pueden fallecer con respecto a todos los que sobreviven. El INL y el IIS finales predicen entre los RN críticamente enfermos quiénes pueden fallecer.

ABSTRACT

Background Passenger lymphocyte syndrome (PLS) causes immune-mediated hemolysis in solid and bone marrow transplant recipients. Donor-derived antibodies against the recipient erythrocyte drive the pathogenesis. It is a rare entity in kidney transplantation, and most of the cases are self-limited. Case presentation A 36-year-old woman presented with fatigue 13 days after living donor renal transplantation. The operation was uneventful, and she was discharged with normal graft functions on the 11th day of transplantation Findings were consistent with cold agglutinin disease at her admission. However, the cold agglutinin test was negative. Eventually, she was diagnosed with PLS. Refractory intravascular hemolysis and frank hemoglobinuria were also present in the patient. Hemolysis was resistant to steroids, intravenous immunoglobulin (IVIG), and Rituximab. Because of life-threatening anemia related to refractory PLS, mycophenolate and tacrolimus were interrupted. However, hemolysis persisted. Following that, immunoadsorption (IA) treatment was obtained. Unfortunately, graft loss occurred due to rejection despite the resolution of PLS after IA. Conclusion PLS is a rare and usually self-limited entity. Our case was an atypical refractory PLS that resembled cold agglutinin disease. Also, frank hemoglobinuria was observed related to severe intravascular hemolysis. These features have not been described before in PLS, to the best of our knowledge. Additionally, IA treatment had never been reported in the literature for PLS, as far as we know. Treatment and management could be a challenge in refractory PLS. Rituximab, IVIG, and extracorporeal treatments could be beneficial. It should be borne in mind that refractory PLS can cause graft and patient loss (AU)


Antecedentes El síndrome de linfocitos pasajeros (PLS) causa hemólisis inmunomediada en receptores de trasplantes sólidos y de médula ósea. Los anticuerpos derivados del donante contra el eritrocito receptor impulsan la patogénesis. Es una entidad rara en el trasplante de riñón y la mayoría de los casos son autolimitados. Presentación del caso Una mujer de 36 años presentó fatiga 13 días después del trasplante renal de donante vivo. La operación transcurrió sin incidentes y fue dada de alta con las funciones normales del injerto el día 11 del trasplante. Los hallazgos coincidían con la enfermedad por crioaglutininas en el momento de su ingreso. Sin embargo, la prueba de crioaglutininas fue negativa. Finalmente, le diagnosticaron PLS. La paciente también presentó hemólisis intravascular refractaria y hemoglobinuria franca. La hemólisis fue resistente a los esteroides, la inmunoglobulina intravenosa (IgIV) y el rituximab. Debido a la anemia potencialmente mortal relacionada con PLS refractario, se interrumpieron el micofenolato y el tacrolimus. Sin embargo, persistió la hemólisis. A continuación, se obtuvo el tratamiento de inmunoadsorción (IA). Desafortunadamente, la pérdida del injerto ocurrió debido al rechazo a pesar de la resolución de PLS después de la IA. Conclusión El PLS es una entidad rara y generalmente autolimitada. Nuestro caso fue un PLS refractario atípico que se asemejaba a la enfermedad por crioaglutininas. Además, se observó hemoglobinuria franca relacionada con hemólisis intravascular grave. Estas características no se han descrito antes en PLS, según nuestro leal saber y entender. Además, el tratamiento IA nunca se había informado en la literatura para PLS, hasta donde sabemos. El tratamiento y el manejo podrían ser un desafío en PLS refractarios. El rituximab, la IgIV y los tratamientos extracorpóreos podrían ser beneficiosos. Debe tenerse en cuenta que los PLS refractarios pueden provocar la pérdida del injerto y del paciente (AU)

ABSTRACT

SUMMARY: In solid and malignant tumors, innate and adaptive immunity are combined in antitumor responses. This study aimed to analyze the activation of plasma cells and the correlation between the infiltration of B and T lymphocytes with the degree of malignancy or Gleason grade in human prostate biopsies diagnosed with cancer. Prostate cancer biopsies were obtained from the Clinical Hospital of Universidad de Chile (n=70), according to the bioethical norms of the institution. Histological sections of 5µm thickness were processed for immunohistochemistry with primary antibodies against BL and total TL (HRP/DAB). Recognition and quantification were performed under a Leica DM750 optical microscope. Microsoft Excel and GraphPad software were used for the statistical study. Correlation coefficient (Pearson) and mean comparison tests (Kruskal-Wallis and Dunn) and p≤ 0.05 were developed. B and T lymphocyte populations were inversely interregulated in prostate cancer (Gleason) (r= -0.46). Their relationship with Gleason grade is variable according to lymphocyte type (LB vs. Gleason r= -0.0.47 and LT vs. Gleason r= -0.21). Histological diagnosis of prostate cancer correlates with a predominance of LT. The malignancy of the pathology correlates with a predominance of LTs, according to the Gleason grade. The increased knowledge of B and T lymphocyte infiltration and plasma cell activation could be used to better target clinical trials on treatments based on immune system responses. Immunotherapy could be a new paradigm to apply better antitumor therapy strategies.


En tumores sólidos y malignos, la inmunidad innata y adaptativa se combinan en respuestas antitumorales. Este estudio tuvo como objetivo analizar la activación de células plasmáticas y la correlación entre la infiltración de linfocitos B y T con el grado de malignidad o grado de Gleason en biopsias de próstata humana diagnosticadas con cáncer. Las biopsias de cáncer de próstata se obtuvieron del Hospital Clínico de la Universidad de Chile (n=70), de acuerdo con las normas bioéticas de la institución. Secciones histológicas de 5 µm de espesor fueron procesadas para inmunohistoquímica con anticuerpos primarios contra LB y LT total (HRP/DAB). El reconocimiento y las cuantificaciones se realizaron bajo un microscopio óptico Leica DM750. Para el estudio estadístico se utilizaron los programas Microsoft Excel y GraphPad. Se desarrollaron pruebas de coeficiente de correlación (Pearson) y comparación de medias (Kruskal-Wallis y Dunn) y p≤ 0.05. Los resultados muestran que las poblaciones de linfocitos B y T están inversamente interreguladas en el cáncer de próstata (r= -0,4578). Su relación con el grado de Gleason es variable según el tipo de linfocito (LB vs Gleason r= -0,47* y LT vs Gleason r= -0,21). Se concluye que la malignidad del cáncer de próstata se correlaciona con un predominio de LT, versus el grado de Gleason. El mayor conocimiento de la infiltración de linfocitos B y T y la activación de células plasmáticas podría aprovecharse para una mejor orientación de ensayos clínicos en tratamientos basados en las respuestas del sistema inmunitario. La inmunoterapia podría ser un nuevo paradigma para aplicar mejores estrategias de terapias antitumorales.

ABSTRACT

Introduction: nutritional status and platelet-to-lymphocyte ratio (PLR) have been found to be associated with prognosis in patients with hepatocellular carcinoma (HCC) undergoing transcatheter arterial chemoembolization (TACE).Objectives: to evaluate the association between nutritional status and PLR in patients with HCC undergoing TACE. Methods: a total of 152 HCC patients received TACE were enrolled. The nutritional status was evaluated by Patient-Generated Subjective Global Assessment (PG-SGA). Patients with PG-SGA A and PG-SGA (B or C) were classified as the well-nourished and malnourished groups. Results: according to the PG-SGA, 130 (85.5 %) patients were malnourished. The median PLR was significantly different between well-nourishedand malnourished groups (p = 0.008). A positive correlation was found between PLR and PG-SGA score (r = -0.265, p = 0.001). The optimalPLR cutoff value was 102.165 to predict malnutrition, with a sensitivity of 65.4 %, specificity of 72.7 %, and an area under the curve (AUC) of0.677 (95 % confidence interval (CI): 0.550-0.804; p = 0.008). A logistic stepwise regression model showed that the PLR was associated withnutritional status in Model 1 without adjustment, as well as if adjusted by age, sex, type of TACE (c-TACE/DEB-TACE) and Child–Pugh stage (oddsratio, 0.190; 95 % CI: 0.062-0.582; p=0.004). Conclusions: nutritional status measured by PG-SGA was significantly associated with PLR in patients with HCC undergoing TACE. (AU)


Introducción: se ha encontrado que el estado nutricional y el índice plaquetas-linfocitos (PLR) se asocian con el pronóstico en pacientes con carcinoma hepatocelular (CHC) sometidos a quimioembolización transarterial (TACE).Objetivos: evaluar la asociación entre el estado nutricional y la PLR en pacientes con CHC sometidos a TACE. Métodos: se evaluaron 152 pacientes con CHC que recibieron TACE. El estado nutricional fue evaluado por Evaluación Global Subjetiva Generada por el Paciente (PG-SGA). Los pacientes con PG-SGA A y PG-SGA (B o C) se clasificaron como los grupos bien nutridos y desnutridos. Resultados: según la PG-SGA, 130 (85,5 %) pacientes estaban desnutridos. La mediana de PLR fue significativamente diferente entre los grupos bien nutridos y desnutridos (p = 0,008). Se encontró una correlación positiva entre PLR y la puntuación PG-SGA (r = -0,265, p = 0,001). El valor de corte óptimo de PLR fue de 102,165 para predecir la malnutrición, con una sensibilidad del 65,4 %, una especificidad del 72,7 % y un área bajo la curva (AUC) de 0,677 (intervalo de confianza [IC] del 95 %: 0,550-0,804; p = 0,008). Un modelo de regresión logística escalonada mostró que el PLR se asoció con el estado nutricional en el Modelo 1 sin ajuste, así como cuando se ajustó por edad, sexo, tipo de TACE (c-TACE/DEB-TACE) y etapa Child-Pugh (odds ratio, 0,190; IC 95 %: 0,062-0,582; p = 0,004).Conclusiones: el estado nutricional medido por PG-SGA se asoció significativamente con PLR en pacientes con CHC sometidos a TACE.

ABSTRACT

Antecedentes: El recuento de linfocitos CD4+ (LTCD4) es una herramienta fundamental para la evaluación y seguimiento de los pacientes que viven con VIH. En Chile, la medición de LTCD4 estandarizada es por citometría de flujo. En el sistema público se realiza en forma centralizada en tres centros. Actualmente existen tecnologías de medición rápida de recuento de LTCD4 en el lugar de atención, permitiendo optimizar la atención de pacientes con infección por VIH. Objetivo: Comparar la precisión de un test rápido de ejecución local versus la técnica estándar. Metodología: Realización de ambas técnicas en un grupo de 102 pacientes durante su control regular de salud. Resultados: El rango de variación promedio de los resultados entre las dos técnicas fue de 10%, con una concordancia en los recuentos de LTCD4 de 97% para el rango de CD4 < 200 cél/uL, de 88% para los pacientes con recuento de LTCD4 entre 200 y 349 cél/uL y de 67% en los rangos superiores. Conclusión: La técnica por test rápido es un sistema fácil de aplicar, de bajo costo, con alta concordancia con la técnica estándar, lo que debería considerarse en la atención de los pacientes que viven con VIH.


Background: The CD4+ lymphocyte cell count is an instrumental tool for the assessment and follow-up in the therapeutic management of patients living with HIV. In Chile, the standardized CD4+ lymphocyte count technique is by flow cytometry. In the public health system, it is performed centralized in 3 sites. Currently, there are technologies that allow measuring the CD4 lymphocyte count at the point of care, allowing to optimize the care of HIV-infected patients. Aim: To compare the accuracy of a point of care rapid test versus the standard technique in patients under regular care at a single HIV center. Results: The average variation of the results between the two techniques was 10%, with a 97% concordance in CD4 range values for patients with CD4 below 200 cells/uL, 88% for CD4 counts between 200 and 349 cells/uL. and 67% above that range. Conclusion: This point of care test is an easy-to-operate, low-cost system with high correlation with the standard technique and should be considered in the care of patients living with HIV.

ABSTRACT

Resumen Si bien la buena adherencia al tratamiento antirretroviral en la infección por el virus de la inmunodeficiencia humana (HIV por Human Immunodeficiency virus en inglés o VIH, por su sigla en español) demostró una sustancial mejoría clínica en las personas que viven con él, lograr el acceso al tratamiento continúa siendo un desafío en los tiempos que corren. Los estudios de laboratorio para diagnóstico y seguimiento de la infección por HIV se centran en estudios virológicos y recuento de linfocitos CD4+ y CD8+. Sin embargo, no se evalúa de forma detallada el perfil inmunológico de las personas que viven con HIV, ni la reconstitución inmune luego de recibido el tratamiento. Es por ello que el objetivo de esta revisión fue describir, por un lado, los diversos estudios realizados desde el laboratorio para el diagnóstico y seguimiento de la infección por HIV. Por otro lado, describir los aportes del laboratorio bioquímico en el estudio del perfil inmunológico de las personas que viven con HIV, el cual incluye desde determinaciones actualmente en uso, hasta nuevos biomarcadores inflamatorios solubles o de membrana celular, como así también las subpoblaciones linfocitarias. Dichos biomarcadores podrían ser herramientas valiosas como descriptores del estado inmunológico de las personas e, incluso, predictores de patologías asociadas a la infección por HIV.


Abstract Although a correct adherence rate to antiretroviral treatment in human immunodeficiency virus (HIV) infection reveals a substantial clinical improvement in people living with HIV, achieving access to treatment is still challenging. Laboratory studies for diagnosis and follow-up are mainly focused on virological status, CD4+ and CD8+ T cells counts. However, the immunological profile of people living with HIV is not evaluated in detail, neither is the immune reconstitution after treatment. Consequently, the aim of this review was is to describe, on the one hand, the studies carried out in the laboratory for the diagnosis and monitoring of HIV infection, and on the other hand, is to describe the contributions of the biochemical laboratory in the study of the immunological profile of people living with HIV. This study includes determinations currently in use, and the determination of new soluble or cell membrane inflammatory biomarkers, as well as T cell subsets. These biomarkers could be valuable tools as descriptors of the impervious state of people, and even predictors of pathologies associated with HIV infection.


Resumo Embora a boa adesão ao tratamento antirretroviral na infecção pelo vírus da imunodeficiência humana (HIV) tenha demonstrado melhora clínica substancial em pessoas que vivem com HIV, conseguir o acesso ao tratamento continua sendo um desafio nos momentos em que correm. Os estudos laboratoriais para diagnóstico e monitoramento da infecção pelo HIV concentram-se em estudos virológicos e contagem de linfócitos CD4+ e CD8+. No entanto, o perfil imunológico das pessoas que vivem com HIV não é avaliado detalhadamente, nem a reconstituição imunológica após o tratamento. É por isso que o objetivo desta revisão foi descrever, por um lado, os vários estudos realizados em laboratório para o diagnóstico e monitoramento da infecção pelo HIV. Por outro lado, descrever as contribuições do laboratório bioquímico no estudo do perfil imunológico de pessoas que vivem com HIV, que inclui desde determinações atualmente em uso, até novos biomarcadores inflamatórios solúveis ou de membrana celular, bem como subpopulações de linfócitos. Esses biomarcadores podem ser ferramentas valiosas como descritores do estado imunológico das pessoas e até mesmo como preditores de patologias associadas à infecção pelo HIV.

ABSTRACT

Abstract Background Subarachnoid hemorrhage (SAH) prognosis remains poor. Vasospasm mechanism might be associated with inflammation. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been studied as inflammation markers and prognostic predictors. Objective We aimed to investigate NLR and PLR in admission as predictors of angiographic vasospasm and functional outcome at 6 months. Methods This cohort study included consecutive aneurysmal SAH patients admitted to a tertiary center. Complete blood count was recorded at admission before treatment. White blood cell count, neutrophil count, lymphocyte count, platelet count, NLR, and PLR were collected as independent variables. Vasospasm occurrence-modified Rankin scale (mRS), Glasgow outcome scale (GOS), and Hunt-Hess score at admission and at 6 months were recorded as dependent variables. Multivariable logistic regression models were used to adjust for potential confounding and to assess the independent prognostic value of NLR and PLR at admission. Results A total of 74.1% of the patients were female, with mean age of 55.6 ± 12.4 years. At admission, the median Hunt-Hess score was 2 (interquartile range [IQR] 1), and the median mFisher was 3 (IQR 1). Microsurgical clipping was the treatment for 66.2% of the patients. Angiographic vasospasm incidence was 16.5%. At 6 months, the median GOS was 4 (IQR 0.75), and the median mRS was 3 (IQR 1.5). Twenty-one patients (15.1%) died. Neutrophil-to-lymphocyte ratio and PLR levels did not differ between favorable and unfavorable (mRS > 2 or GOS < 4) functional outcomes. No variables were significantly associated with angiographic vasospasm. Conclusion Admission NLR and PLR presented no value for prediction of functional outcome or angiographic vasospasm risk. Further research is needed in this field.


Resumo Antecedentes O prognóstico da hemorragia subaracnoidea (HSA) permanece ruim. Vasoespasmo pode estar associado à inflamação. Razões neutrófilo-linfócito (NLR) e plaqueta-linfócito (PLR) têm sido estudadas como marcadores de inflamação e prognóstico. Objetivo Investigar NLR e PLR na admissão como preditores de vasoespasmo angiográfico e desfecho aos 6 meses. Métodos Este estudo de coorte incluiu pacientes consecutivos com HSA aneurismática de um centro terciário. Contagem de leucócitos, neutrófilos, linfócitos e plaquetas, proporção de neutrófilos para linfócitos e de plaquetas para linfócitos foram coletados como variáveis independentes. Ocorrência de vasoespasmo, escala de Rankin modificada, escala de desfecho de Glasgow e o escore de Hunt-Hess na admissão e 6 meses após a mesma foram registradas como variáveis dependentes. Modelos de regressão logística multivariável foram usados para ajustar potenciais fatores de confusão e avaliar valor prognóstico independente de NLR e PLR. Resultados Um total de 74,1% pacientes eram do sexo feminino, com idade média de 55,6 ± 12,4 anos. Na admissão, a pontuação média de Hunt-Hess foi de 2 (IQR 1) e a mediana de mFisher foi de 3 (IQR 1). Clipagem microcirúrgica foi o tratamento escolhido para 66,2% dos pacientes. A incidência de vasoespasmo angiográfico foi de 16,5%. Aos 6 meses, a escala de desfecho de Glasgow mediana era 4 (IQR 0,75) e a escala de Rankin modificada mediana era 3 (IQR 1,5). Vinte e um pacientes (15,1%) morreram. Os níveis de NLR e PLR não diferiram entre resultados funcionais favoráveis e desfavoráveis (mRS > 2 ou GOS < 4). Nenhuma variável foi significativamente associada ao vasoespasmo angiográfico. Conclusão Razão neutrófilo-linfócito e a PLR não apresentaram valor preditivo de desfecho funcional ou risco de vasoespasmo angiográfico. Mais pesquisas são necessárias neste campo.
