Caracterización clínica y epidemiológica de los pacientes con hepatitis alcohólica en el Hospital Regional de Talca: estudio retrospectivo de 5 años (2017-2022) / Clinical and epidemiological characterisation of patients with alcoholic hepatitis in the Regional Hospital of Talca - 5-year retrospective study (2017-2022)

Alcoholic Hepatitis (HA) represent to one of the pathological entities in the context of liver damage associated with excessive and prolonged alcohol consumption. Despite its high mortality, making the early diagnosis is still a challenge for physicians. The local information of this pathology is limited, so this work consists of conducting a retrospective study on the clinical and epidemiological characteristics of patients diagnosed with HA at the Regional Hospital of Talca (HRT); in order to make available to the treating doctors, the greatest amount of data contributing to decision-making for the benefit of patients. Methods: The clinical records of all patients discharged from the HRT with a diagnosis of HA during the period between January 2017 and August 2022 were reviewed. Background information such as: chief complaint, main symptoms, comorbidities, laboratory tests, treatment, evolution and survival, etc., was collected for analysis and to obtain the conclusions presented. Results: A total of 16 patients were studied; 93.75 % were male and 6.24 % female; with a mean age of 52. Of the patients, 87.5 % had a history of DHC. All had alcohol abuse for more than 5 years and 93.75% had active alcoholism. The most frequent laboratory findings included hyperbilirubinaemia (93.75 %), GOT/GPT ratio >2 (50 %) and leukocytosis (56.25 %). Of the total patients studied, 68.75% had a survival of more than 1 year after the event, while 12.5% died during hospitalisation.

Asociación entre los niveles séricos de vitamina D y marcadores inflamatorios en pacientes en hemodiálisis / Association between vitamin D serum levels and inflammatory markers in patients on hemodialysis

Resumen Introducción: La relación entre 25-OH-vitamina D y el sistema inmune en pacientes con enfermedad renal crónica es objeto de atención. Objetivos: Evaluar la prevalencia de la deficiencia de vitamina D en pacientes en hemodiálisis e investigar la asociación entre la vitamina D y proteína C reactiva ultrasensible (PCRus), índice neutrófilo/linfocito (INL) e índice plaqueta/linfocito (IPL). Método: Estudio transversal de 80 pacientes en hemodiálisis, divididos en dos grupos: un nivel sérico de 25-OH-vitamina D < 20 ng/mL se consideró como deficiencia de vitamina D y ≥ 20 ng/mL, como normal. Con el análisis de correlación de Spearman se definió la relación entre los parámetros. Resultados: 40 % de los pacientes presentó deficiencia de vitamina D. Hubo diferencias significativas entre los grupos en PCRus (p = 0.047), INL (p = 0.039), IPL (p = 0.042) y tratamiento con análogos de vitamina D (p = 0.022). La vitamina D tuvo una correlación negativa significativa con PCRus (p = 0.026), INL (p = 0.013) e IPL (p = 0.022). Conclusiones: La deficiencia de vitamina D fue de 40 %. Los niveles de PCRus, INL e IPL fueron significativamente más altos ante deficiencia de vitamina D. Se encontró correlación inversa significativa entre vitamina D y PCRus, INL e IPL.

Abstract Introduction: The relationship between 25-OH-vitamin D and the immune system in patients with chronic kidney disease is a subject of attention. Objectives: To assess the prevalence of vitamin D deficiency in patients on hemodialysis and to investigate the association between vitamin D, ultra-sensitive C-reactive protein (US-CRP), neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). Method: Cross-sectional study of 80 patients on hemodialysis, divided into two groups: a serum 25-OH-vitamin D level < 20 ng/mL was considered to be vitamin D deficiency and a serum level ≥ 20 ng/mL was regarded as normal. The relationship between the parameters was defined with Spearman’s correlation analysis. Results: 40 % of the patients had vitamin D deficiency. There were significant differences between groups in US-CRP (p = 0.047), NLR (p = 0.039), PLR (p = 0.042) and treatment with vitamin D analogues (p = 0.022). Vitamin D had a significant negative correlation with US-CRP (p = 0.026), NLR (p = 0.013) and PLR (p = 0.022). Conclusions: The prevalence of vitamin D deficiency was 40 %. The values of US-CRP, NLR and PLR were significantly higher in the presence of vitamin D deficiency. A significant inverse correlation was found between vitamin D levels and US-CRP, NLR and PLR.

Niveles Plasmáticos de Citoquinas Proinflamatorias en Cáncer de Próstata / Serum levels of proinflammatory cytokines in prostate cancer

INTRODUCTION: Prostate cancer has become an important public health problem affecting millions of men worldwide every year. Like other malignant tumors, prostate cancer shows evidence of a strong inflammatory component that is dependent on the release of pro-inflammatory cytokines, which might play a major role in the development and progression of the tumor, helping in its early stage, progression and aggressiveness. AIMS: The goal of this study was to determine the relationships between the serum levels of pro-inflammatory cytokines and the different stages of prostate cancer. To this end, sera from patients enrolled by The Laboratory of Metabolic Diseases and Cancer of the Faculty of Pharmacy and Biochemistry at the University Juan Agustín Maza in Argentina, were analyzed through ELISA and their pro-inflammatory cytokines (IL-6, TNF-α and MCP-1) quantified. Patients were first classified into three groups (Control, at Risk, and Cancer subjects) and anthropometric, biochemical and histological parameters of prostate were then determined for all groups. RESULTS AND CONCLUSIONS: Despite displaying elevated serum concentrations of IL-6 and TNF-α in the Cancer and the Risk groups compared to the Control group, the differences did not reach significance. However, there was a positive correlation between these cytokines only in the Risk and Cancer groups, showing a general inflammatory behavior in these patients. The results obtained provide general data about the behavior of pro-inflammatory cytokines in prostate cancer. However, they do not demonstrate a direct correlation between serum levels and neoplastic progression. Nevertheless, these findings do not rule out a possible relationship between prostate cancer and serum levels of pro-inflammatory cytokines.

Association of measures of central fat accumulation indices with body fat distribution and metabolic, hormonal, and inflammatory parameters in women with polycystic ovary syndrome

ABSTRACT Objective To investigate the associations among visceral adiposity index (VAI), lipid accumulation product (LAP), body fat percentage (%), and android/gynoid ratio (A/G ratio) in women with polycystic ovary syndrome (PCOS) and verify if the parameters representative of visceral obesity correlate with and exhibit the same frequency as body composition variables; anthropometric indices; and metabolic, hormonal, and inflammatory parameters. Subjects and methods This was a cross-sectional study that included 94 women with PCOS. Hormonal, metabolic, and inflammatory parameters were analyzed in all women. Free androgen index (FAI) and homeostasis model assessment (HOMA-IR), as well as LAP, VAI, and anthropometric indices, were calculated. The regions of interest (ROIs) in body composition and body composition indices were evaluated using a dual X-ray absorptiometry (DXA). Overall, 32 variables were selected as markers of body fat distribution. Results Among the 32 markers evaluated, 29 correlated with LAP, whereas 25 correlated with VAI, 19 with body fat (%), and 30 with A/G ratio. Additionally, some markers correlated with the four adiposity indices evaluated: ROIs, except for total mass and leg fat (%); body composition (body mass index, waist circumference, and hip circumference) indices; fasting insulin; and C-reactive protein. Conclusion LAP and VAI may be sensitive measures for screening and preventing metabolic syndrome and insulin resistance in PCOS, with LAP being more sensitive than VAI, and the A/G ratio may be more sensitive than body fat percentage.

Hematologic parameters and neutrophil / lymphocyte ratio in the prediction of urethroplasty success

ABSTRACT Objective: The pathophysiology of urethral stricture and its recurrence remains vague and one of the important causes is progressive inflammation. It has been shown in recent years that the neutrophil / lymphocyte ratio is a marker of systemic inflammation and is associated with prognosis in many cardiovascular diseases, malignancies and chronic inflammatory diseases. We assessed simple systemic inflammation markers preoperatively and surgical techniques for urethral stricture recurrence after urethroplasty. Patients and Methods: After exclusion criteria applied, a total of 117 male cases operated with urethroplasty in our clinic between January 2012 and June 2017 were included in the study and analyzed retrospectively. Localization and length of the strictures of the patients, neutrophil counts and percentages, lymphocyte counts and percentages, and neutrophil / lymphocyte ratios in preoperative peripheral blood samples were statistically analyzed. Recurrent stricture during first 12 months follow-up after the surgery has been assessed as recurrence. Results: The mean age of the patients was 54.12 ± 16.35 and the mean urethral stricture length was 3.44 ± 1.83 cm. Recurrence was observed in 30.1% of cases who received buccal graft, 30% in penile skin applied cases and 26.1% of cases treated with end-to-end anastomosis and there was no statistically significant difference between neutrophil, lymphocyte, neutrophil / lymphocyte ratio and average stricture segment length between recurrent and non-recurrent cases (p > 0.005). Conclusions: We consider that neutrophil, lymphocyte counts and their ratio prior to urethroplasty and the technique performed are not parameters that can be used to predict stricture recurrence. Prospective and randomized new trials with larger patient populations are needed to make more accurate judgments about the role of these inflammatory parameters.

Inflammatory biomarkers in sera of patients with intervertebral disc degeneration / Biomarcadores inflamatórios no plasma de pacientes com degeneração do disco intervertebral

ABSTRACT Objective: To evaluate intervertebral disc levels of inflammatory factor (interleukin 6) and proteinase activity (cathepsin B) in patients with a degenerative disease and serum levels of interleukin 6, serum cathepsin B activity and hyaluronic acid biomarkers. Methods: We conducted immunohistochemistry studies of intervertebral discs to analyze interleukin 6 and cathepsin B levels of patients with degenerative disease and spine fracture (Control Group) and to measure hyaluronic acid, interleukin 6 and cathepsin B activity from sera of intervertebral disc degeneration patients, fracture patients, and healthy individuals. Results: Interleukin 6 and cathepsin B seem to be related with physiopathology of intervertebral disc degeneration, since the levels of both were higher in discs of patients with intervertebral disc degeneration. Interleukin 6 and cathepsin B do not represent good biomarkers of degenerative intervertebral disc disease, since the level of such compounds is increased in the plasma of patients with fractures. Conclusion: Hyaluronic acid can be a biomarker for intervertebral disc degeneration, because hyaluronic acid levels were higher only in sera of patients with intervertebral disc degeneration.

RESUMO Objetivo: Avaliar os níveis de fatores inflamatórios nos discos intervertebrais (interleucina 6) e proteinase (catepsina B) em pacientes com doença degenerativa de disco intervertebral, além de verificar os níveis séricos de interleucina 6, ácido hialurônico e atividade sérica da catepsina B. Métodos: Foi realizado exame imuno-histoquímica dos discos intervertebrais de pacientes com doença degenerativa e fratura da coluna (Grupo Controle) e análise do plasma de pacientes com doença degenerativa de disco intervertebral. Como controle, foram utilizados plasma de pacientes com fraturas, além de indivíduos saudáveis. Resultados: Interleucina 6 e catepsina B sugerem relação com a fisiopatologia da doença degenerativa de disco intervertebral, uma vez que os níveis de ambos foram maiores nos discos de pacientes com doença degenerativa de disco intervertebral. Interleucina 6 e catepsina B não representam bons biomarcadores da doença degenerativa do disco intervertebral, já que também encontram níveis aumentados em plasma de pacientes com fratura. Conclusão: O ácido hialurônico é um possível biomarcador de doença degenerativa de disco intervertebral, porque os níveis de ácido hialurônico foram maiores apenas em plasma de pacientes com doença degenerativa de disco intervertebral.

C-reactive protein/albumin ratio is associated with lung function among children/adolescents with cystic fibrosis: a three-year longitudinal study

ABSTRACT BACKGROUND: Chronic lung infections, inflammation and depletion of nutritional status are considered to be prognostic indicators of morbidity in patients with cystic fibrosis. The aim of this study was to investigate the association between inflammatory markers and lung function, nutritional status and morbidity among children/adolescents with cystic fibrosis. DESIGN AND SETTINGS: Prospective three-year longitudinal study conducted in an outpatient clinic in southern Brazil. METHODS: Children/adolescents aged 1-15 years with cystic fibrosis were enrolled. Nutritional status was determined from weight-to-length and body mass index-to-age z-scores and was classified as acceptable, at risk or nutritional failure. Tumor necrosis factor-α, interleukin-1β, myeloperoxidase, C-reactive protein and C-reactive protein/albumin ratio were analyzed. Lung function was evaluated based on the forced expiratory volume in the first second and morbidity according to the number of hospitalizations for pulmonary exacerbation and infections by Pseudomonas aeruginosa. Lung function, nutritional status and morbidity were the outcomes. Odds ratios and 95% confidence intervals were to evaluate the effect of baseline inflammatory markers on the clinical outcomes after three years of follow-up and p-values < 0.05 were considered significant. RESULTS: We evaluated 38 children/adolescents with cystic fibrosis: 55% female; median age (with interquartile range), 3.75 years (2.71-7.00). Children/adolescents with high C-reactive protein/albumin ratio at baseline had odds of 18 (P = 0.018) of presenting forced expiratory volume in the first second ≤ 70% after three years. The other inflammatory markers were not associated with the outcomes. CONCLUSION: C-reactive protein/albumin ratio was associated with forced expiratory volume in the first second ≤ 70% after three years.

Decreased muscle strength is associated with proinflammatory cytokines but not testosterone levels in men with diabetes

The aim of this study was to compare muscle strength in male subjects with type 2 diabetes mellitus (DM2) with and without low plasma testosterone levels and assess the relationship between muscle strength, testosterone levels, and proinflammatory cytokines. Males (75) aged between 18 and 65 years were divided into 3 groups: control group that did not have diabetes and had a normal testosterone plasma level (>250 ng/dL), DnormalTT group that had DM2 with normal testosterone levels, and the DlowTT group that had DM2 and low plasma testosterone levels (<250 ng/dL). The age (means±SD) of the groups was 48.4±10, 52.6±7, and 54.6±7 years, respectively. Isokinetic concentric and isometric torque of knee flexors and extensors were analyzed by an isokinetic dynamometer. Plasma testosterone and proinflammatory cytokine levels were determined by chemiluminescence and ELISA, respectively. Glycemic control was analyzed by glycated hemoglobin (HbA1C). In general, concentric and isometric torques were lower and tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β plasma levels were higher in the groups with diabetes than in controls. There was no correlation between testosterone level and knee torques or proinflammatory cytokines. Concentric and isometric knee flexion and extension torque were negatively correlated with TNF-α, IL-6, and HbA1C. IL-6 and TNF-α were positively correlated with HbA1C. The results of this study demonstrated that muscle strength was not associated with testosterone levels in men with DM2. Low muscle strength was associated with inflammatory markers and poor glycemic control.

Inflammatory biomarkers responses after acute whole body vibration in fibromyalgia

The aims of this study were 1) to characterize the intensity of the vibration stimulation in women diagnosed with fibromyalgia (FM) compared to a control group of healthy women (HW) matched by age and anthropometric parameters, and 2) to investigate the effect of a single session of whole body vibration (WBV) on inflammatory responses. Levels of adipokines, soluble tumor necrosis factor receptors (sTNFr1, sTNFr2), and brain-derived neurotrophic factor (BDNF) were determined by enzyme-linked immunosorbent assay. Oxygen consumption (VO2) was estimated by a portable gas analysis system, heart rate (HR) was measured using a HR monitor, and perceived exertion (RPE) was evaluated using the Borg scale of perceived exertion. Acutely mild WBV increased VO2 and HR similarly in both groups. There was an interaction (disease vs vibration) in RPE (P=0.0078), showing a higher RPE in FM compared to HW at rest, which further increased in FM after acute WBV, whereas it remained unchanged in HW. In addition, there was an interaction (disease vs vibration) in plasma levels of adiponectin (P=0.0001), sTNFR1 (P=0.000001), sTNFR2 (P=0.0052), leptin (P=0.0007), resistin (P=0.0166), and BDNF (P=0.0179). In conclusion, a single acute session of mild and short WBV can improve the inflammatory status in patients with FM, reaching values close to those of matched HW at their basal status. The neuroendocrine mechanism seems to be an exercise-induced modulation towards greater adaptation to stress response in these patients.

The relationship between circulating irisin, retinol binding protein-4, adiponectin and inflammatory mediators in patients with metabolic syndrome

ABSTRACT Objective We wanted to investigate whether there is a relationship between circulating irisin, retinol binding protein-4 (RBP-4), adiponectin and proinflammatory mediators implicated in the development of insulin resistance (IR) in metabolic syndrome (MetS). Subjects and methods In 180 individuals, including controls and patients with MetS, we measured fasting plasma insulin, high sensitivity C-reactive protein (hsCRP), pentraxin-3 (PTX-3), interleukin-33 (IL-33), irisin, RBP-4, and adiponectin using ELISA kits. Results While fasting plasma hsCRP, PTX-3, IL-33, irisin, RBP-4 concentrations were higher, adiponectin levels were lower in patients with MetS than in controls. A correlation analysis revealed that plasma irisin levels were positively associated with MetS components such as waist circumference and waist-hip ratio, low density lipoprotein (LDL) and markers of systemic inflammation such as PTX-3, hsCRP, uric acid, and RBP-4. Adiponectin levels were negatively associated with waist circumference, waist-hip ratio, PTX-3 and LDL. Conclusions Although the precise mechanisms are still unclear, irisin, RBP-4, adiponectin and PTX-3 are hallmarks of the MetS, which is related to low-grade inflammation. It is conceivable that irisin and adiponectin might contribute to the development of MetS and may also represent novel MetS components. Future clinical studies are needed to confirm and extend these data.

Differences in Hepatic Expression of Iron, Inflammation and Stress-Related Genes in Patients with Nonalcoholic Steatohepatitis

Abstract: Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease worldwide. We have previously shown that hepatic reticuloendothelial system (RES) iron deposition is associated with an advanced degree of nonalcoholic steatohepatitis (NASH) in humans. In this study, we aimed to determine differentially expressed genes related to iron overload, inflammation and oxidative stress pathways, with the goal of identifying factors associated with NASH progression. Seventy five patients with NAFLD were evaluated for their biochemical parameters and their liver tissue analyzed for NASH histological characteristics. Gene expression analysis of pathways related to iron homeostasis, inflammation and oxidative stress was performed using real-time PCR. Gene expression was compared between subjects based on disease status and presence of hepatic iron staining. We observed increased gene expression of hepcidin (HAMP) (2.3 fold, p = 0.027), transmembrane serine proteinase 6 (TMPRSS6) (8.4 fold, p = 0.003), signal transducer and activator of transcription 3 (STAT3) (5.5 fold, p = 0.004), proinflammatory cytokines; IL-1β (2.7 fold, p = 0.046) and TNF-α (3.8 fold, p = 0.001) in patients with NASH. TMPRSS6, a negative regulator of HAMP, is overexpressed in patients with NASH and HIF1α (hypoxia inducible factor-1) is downregulated. NAFLD patients with hepatic iron deposition exhibited higher hepcidin expression (3.1 fold, p = 0.04) but lower expression of cytokines. In conclusion, we observed elevated hepatic HAMP expression in patients with NASH and in NAFLD patients who had hepatic iron deposition, while proinflammatory cytokines displayed elevated expression only in patients with NASH, suggesting a regulatory role for hepcidin in NAFL to NASH transition and in mitigating inflammatory responses.

The role of neutrophil lymphocyte ratio to leverage the differential diagnosis of familial Mediterranean fever attack and acute appendicitis

BACKGROUND/AIMS: Familial Mediterranean fever (FMF) is an autosomal recessive disorder characterized by attacks of fever and diffuse abdominal pain. The primary concern with this presentation is to distinguish it from acute appendicitis promptly. Thus, we aimed to evaluate the role of neutrophil lymphocyte ratio (NLR) to leverage the differential diagnosis of acute FMF attack with histologically proven appendicitis. METHODS: Twenty-three patients with histologically confirmed acute appendicitis and 88 patients with acute attack of FMF were included in the study. NLR, C-reactive protein and other hematologic parameters were compared between the groups. RESULTS: Neutrophil to lymphocyte ratio was significantly higher in patients with acute appendicitis compared to the FMF attack group (8.24 +/- 6.31 vs. 4.16 +/- 2.44, p = 0.007). The performance of NLR in diagnosing acute appendicitis with receiver operating characteristic analysis with a cut-off value of 4.03 were; 78% sensitivity, 62% specificity, and area under the curve 0.760 (95% confidence interval, 0.655 to 0.8655; p < 0.001). CONCLUSIONS: This study showed that NLR, the simple and readily available inflammatory marker may have a useful role in distinguishing acute FMF attack from acute appendicitis.

Prognostic Inflammation Score in Surgical Patients with Colorectal Cancer

Several inflammatory markers have been investigated as prognostic parameters in a variety of cancer population with mostly favorable results. This study aimed to verify the significance of common inflammatory markers as prognostic variables and assess whether a selective combination of them as prognostic inflammation score (PIS) could further improve their prognostic values in surgical patients with colorectal cancer (CRC). A total of 265 patients who had undergone curative resection of CRC were reviewed retrospectively. Preoperative levels of inflammatory markers such as serum C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), white blood cell count (WBC), and neutrophil/lymphocyte ratio (NLR) were assessed by uni- and multivariate survival analysis with disease-free (DFS) and disease-specific survival (DSS). PIS was constructed with a selective combination of inflammatory markers which were independently significant. On univariate analysis, CRP, ESR, and NLR were significantly associated with DFS and DSS. On multivariate analysis, CRP and NLR were independently significant prognostic variables for DSS and DFS respectively (P=0.013, P=0.021). When PIS was constructed with combination of CRP and NLR, it was independently and significantly associated with both DFS and DSS (P=0.006, P=0.010). Furthermore, PIS was superior to CRP for DSS (HR=15.679 vs. HR=5.183), and NLR for DFS in terms of prognosticating power (HR=4.894 vs. HR=2.687). When PIS is constructed with combination of CRP and NLR, it is a potentially significant prognostic variable associated with poor survival regardless pathologic prognostic variables in patients with CRC after curative resection.

Cutoff value of serum procalcitonin as a diagnostic biomarker of infection in end-stage renal disease patients

BACKGROUND/AIMS: Serum procalcitonin (PCT) levels are low in healthy individuals but are elevated in patients with a serious bacterial infection or sepsis. In this study, we examined the ability of serum PCT concentration to diagnose infections in end-stage renal disease (ESRD) patients, and sought to determine an appropriate threshold level. METHODS: Serum PCT levels were measured in ESRD patients on antibiotic therapy for a suspected bacterial infection (ESRD infection [iESRD] group, n = 21), and compared with those of ESRD patients on hemodialysis with no sign of infection (ESRD control [cESRD] group, n = 20). RESULTS: The mean serum PCT concentration of the iESRD group was significantly higher than in the cESRD group (2.95 +/- 3.67 ng/mL vs. 0.50 +/- 0.49 ng/mL, p = 0.006), but serum PCT concentrations did not correlate with severity of infection. The optimized threshold level derived for serum PCT was 0.75 ng/mL, rather than the currently used 0.5 ng/mL; this threshold demonstrated a sensitivity and specificity of 76.2% and 80.0% for infection and 100% and 60.6% for systemic inflammatory response syndrome, respectively, compared with the cutoff of 0.5 ng/mL. CONCLUSIONS: This study suggests that serum PCT at a cutoff value of 0.75 ng/mL is an appropriate indicator of infection in ESRD patients.

The prognostic impact of inflammatory factors in patients with multiple myeloma treated with thalidomide in Korea

BACKGROUND/AIMS: The purpose of this study was to determine the correlations between inflammatory factors-including absolute lymphocyte count, lactate dehydrogenase, beta2-microglobulin, albumin, C-reactive protein, and ferritin-and the prognosis for survival in patients with multiple myeloma (MM) treated with induction chemotherapy containing thalidomide and who underwent autologous stem cell transplantation (ASCT). METHODS: Data from patients at 13 university hospitals in South Korea were collected retrospectively between December 2005 and May 2013. RESULTS: The median age of the 232 patients was 57 years (range, 33 to 77) and the male to female ratio was 1.09:1. In the multivariate analysis, fewer than two combined abnormal inflammatory factors was the only independent prognostic factor for superior progression-free survival (relative risk [RR], 0.618; 95% confidence interval [CI], 0.409 to 0.933; p = 0.022), and platelet count > 100 x 109/L and fewer than two combined abnormal inflammatory factors were independent prognostic factors for superior overall survival (RR, 4.739; 95% CI, 1.897 to 11.839; p = 0.001 and RR, 0.263; 95% CI, 0.113 to 0.612; p = 0.002, respectively). CONCLUSIONS: Patients with two or more than two combined inflammatory factors who were treated with thalidomide induction chemotherapy and who underwent ASCT showed significantly shorter survival compared to those with fewer than two combined inflammatory factors. These results could be helpful for predicting prognosis in patients with MM.

Efeito do tratamento periodontal não-cirúrgico sobre o controle glicêmico, mediadores inflamatórios e adipocinas em pacientes com diabetes mellitus tipo 2 e periodontite crônica severa / Effect of non-surgical periodontal treatment on glycemic control, inflammatory mediators and adipokines in patients with type 2 diabetes and severe chronic periodontitis

O objetivo do presente estudo foi avaliar o efeito do tratamento periodontal não cirúrgico sobre o controle glicêmico e os níveis séricos de adipocinas e mediadores inflamatórios em pacientes com periodontite crônica e diabetes mellitus tipo 2 (DM2). Foram selecionados 41 pacientes com periodontite crônica severa e com DM2, que foram aleatoriamente alocados em dois grupos: o grupo teste (21 pacientes, idade média de 58,1 ± 8,4 anos, 11 homens e 10 mulheres), que foram submetidos ao tratamento periodontal não cirúrgico; e o grupo controle (20 pacientes, idade média de 54,1 ± 9,9 anos, 14 homens e 6 mulheres), que permaneceram sem tratamento periodontal. Os parâmetros clínicos (profundidade de sondagem ­ PS, nível de inserção clínica ­ NIC, SS - sangramento à sondagem e índice de placa ­ IP), os laboratoriais (hemoglobina glicada ­ HbA1c, colesterol total ­ CT, HDL, LDL e triglicerídeos) e os marcadores inflamatórios (interleucinas - 1ß e -6, fator de necrose tumoral-α, resistina, leptina e adiponectina) foram avaliados inicialmente (dia 0) e 90 dias após a terapia periodontal. Os resultados obtidos indicaram uma redução na % dos sítios com SS, IP e nos sítios com PS ≥ 6mm no grupo teste (P <0.05). Os níveis de HbA1c, glicose estimada, IL-1ß, TNF-α e resistina também diminuíram significativamente neste grupo. Os demais marcadores não tiveram alterações significantes em ambos os grupos. Concluindo, o tratamento periodontal não cirúrgico da periodontite crônica severa foi associado à melhora do controle glicêmico e à diminuição nos níveis de IL-1ß, TNF-α e resistina após 3 meses, em pacientes com diabetes mellitus tipo 2.

The aim of this study was to evaluate the effects of non-surgical periodontal treatment on glycemic control, adipokines and systemic inflammatory mediators levels in patients with severe chronic periodontitis and diabetes mellitus type 2 (DM2). Fourty-one patients with severe chronic periodontitis and DM2 were randomly allocated in the test group (21 patients, mean age 58.1 ± 8.4 years, 11 men and 10 women) underwent nonsurgical periodontal treatment; and the control group (20 patients, mean age 54.1 ± 9.9 years, 14 men and 6 women) who remained untreated. The clinical parameters (probing depth - PD, clinical attachment level - CAL, BOP- bleeding on probing and plaque index - PI), laboratory (glycated hemoglobin - HbA1c, total cholesterol - TC, HDL, LDL and triglycerides) and inflammatory mediators (interleukin - 1ß and -6, tumor necrosis factor-α, resistin, leptin and adiponectin) were evaluated at baseline and 90 days after periodontal therapy. After 90 days, there was a reduction in the% of sites with BOP, PI and sites with PD ≥ 6 mm in the test group. HbA1c levels, estimated glucose, IL-1ß, TNF-α and resistin also significantly decreased in this group. There were no significant changes in the other markers in both groups. In conclusion, non-surgical periodontal treatment improved glycemic control in patients with severe chronic periodontitis and DM2. IL-1ß, TNF-α and resistin levels decreased significantly after 3 months of the treatment.

Nutraceutical preconditioning with arginine and oil mixes. Effects on inflammatory mediators, oxidative stress and lipid profile in patients undergoing radical prostatectomy

PURPOSE: To investigate whether there is any effect resulting from preconditioning with nutraceutical supplementation containing arginine and oil mixes with high ω9:ω6 ratio and low ω6:ω3 ratio containing EPA and DHA, ALA fatty acids on inflammatory mediators, antioxidant and lipid profile modulation in surgical trauma. METHODS: Twenty-six men scheduled for radical prostatectomy were randomized into three groups and treated as follows: Group 1 (skim milk, 0% fat), Group 2 (supplement with ω6:ω3 ratio of 8:1 and arginine) and Group 3 (supplement with high ω9:ω6 ratio of 3.2:1 and low ω6:ω3 ratio of 1.4:1 and arginine). Patients received skin milk or supplements twice a day (200 ml) during five days prior to surgery. Peripheral venous blood samples were collected at three different timepoints: five days before surgery (PRE), before anesthesia induction (IND) and on the 2nd postoperative day (POS). Parameters analyzed included inflammatory cytokines (IL-1β, IL-6, IL-8 and TNF-α), antioxidants (catalase), lipid profile and heat shock protein (HSP-27). RESULTS: There were no significant differences between groups on inflammatory mediators and antioxidant parameters. However, lipid profile values (Cholesterol, LDL, Triglycerides, VLDL), were significantly different. CONCLUSION: Preconditioning with arginine and oil mixes containing high ω9:ω6 ratio and low ω6:ω3 ratio, has no effects on inflammatory mediators and oxidative stress in patients undergoing radical prostatectomy. Reduction of cholesterol, triglycerides, LDL and VLDL profiles may be related to the trauma effect. .

A randomized triple-masked controlled trial on the effects of synbiotics on inflammation markers in overweight children / Ensaio clínico controlado randomizado triplo-cego dos efeitos de simbióticos sobre marcadores de inflamação em crianças com sobrepeso

OBJECTIVE: the low degree of inflammation in obesity contributes to systemic metabolic dysfunction. Recent experimental studies proposed some effects of alteration in gut microbiota on inflammatory factors. This study aimed to assess the anti-inflammatory effects of a synbiotic supplement on inflammation markers in overweight and obese children and adolescents. METHODS: this randomized triple-masked controlled trial was conducted among 70 participants aged 6 to 18 years, with a body mass index (BMI) equal or higher than the 85th percentile. They were randomly assigned into two groups of equal number to receive synbiotic or placebo for eight weeks. RESULTS: fifty-six of 70 participants (80%) completed the study. Compared with the placebo group, the synbiotic group had significant decrease in mean values of tumor necrosis-α and interleukin-6, with significant increase in adiponectin; these changes were no longer significant after adjustment for BMI. There was no significant change in the mean values of high-sensitive C-reactive protein. CONCLUSION: the present findings suggest the positive influence of synbiotic supplementation on inflammation factors, which are dependent to its effect on weight reduction in overweight and obese children. .

OBJETIVO: o baixo grau de inflamação na obesidade contribui para disfunção metabólica sistêmica. Estudos experimentais recentes propuseram alguns efeitos de alteração na microbiota intestinal sobre fatores inflamatórios. O objetivo deste estudo foi avaliar os efeitos anti-inflamatórios de um suplemento simbiótico sobre marcadores de inflamação em crianças e adolescentes com sobrepeso e obesos. MÉTODOS: este ensaio clínico controlado randomizado triplo-cego foi conduzido entre 70 participantes com idade entre seis e 18 anos, com índice de massa corporal (IMC) igual ou acima do 85º percentil. Eles foram aleatoriamente divididos em dois grupos de igual número de participantes para receber simbiótico ou placebo por oito semanas. RESULTADOS: no todo, 56 de 70 participantes (80%) concluíram o estudo. Em comparação ao grupo placebo, o grupo simbiótico teve redução significativa nos valores médios de necrose tumoral-α e interleucina-6, com aumento significativo na adiponectina; essas alterações não eram mais expressivas após o ajuste do IMC. Não houve alteração importante nos valores médios da proteína C-reativa altamente sensível. CONCLUSÃO: nossas conclusões sugerem a influência positiva da suplementação simbiótica sobre fatores inflamatórios, dependente de seu efeito sobre a redução de peso em crianças com sobrepeso e obesas. .

Manejo da resposta inflamatória pós-circulação extracorpórea: revisão dos estudos em modelos animais / Managing the inflammatory response after cardiopulmonary bypass: review of the studies in animal models

Objetivo: Revisar estudos realizados em modelos animais avaliando intervenções terapêuticas e resposta inflamatória e alterações da microcirculação após instalação de circulação extracorpórea. Métodos: Utilizada a estratégia de busca ("Cardiopulmonary Bypass"(MeSH)) AND ("Microcirculation"(MeSH) OR "Inflammation"(MeSH) OR "Inflammation Mediators"(MeSH)). Resultados repetidos, estudos humanos, artigos em língua não inglesa, revisões e estudos sem controle foram excluídos. Resultados: Filtros sanguíneos, miniaturização do sistema, perfusatos específicos, perfusão regional, fluxo e temperatura adequados e terapias farmacológicas com fármacos anticoagulantes, vasoativos e anti-inflamatórios reduziram alterações em microcirculação e resposta inflamatória. Conclusão: A eficácia demonstrada em modelos animais estabelece uma perspectiva para avaliação dessas intervenções na prática clínica. .

Objective: To review studies performed in animal models that evaluated therapeutic interventions to inflammatory response and microcirculatory changes after cardiopulmonary bypass. Methods: It was used the search strategy ("Cardiopulmonary Bypass" (MeSH)) and ("Microcirculation" (MeSH) or "Inflammation" (MeSH) or "Inflammation Mediators" (MeSH)). Repeated results, human studies, non-English language articles, reviews and studies without control were excluded. Results: Blood filters, system miniaturization, specific primers regional perfusion, adequate flow and temperature and pharmacological therapies with anticoagulants, vasoactive drugs and anti-inflammatories reduced changes in microcirculation and inflammatory response. Conclusion: Demonstrated efficacy in animal models establishes a perspective for evaluating these interventions in clinical practice. .
