[Pro-inflammatory cytokines related to severity and mortality in type 2 diabetes patients with soft tissue infection]. / Citocinas, diabetes e infección de tejidos blandos. Su relación con la severidad y mortalidad.

OBJECTIVE: to determine the relation between IL6, IL10 and TNFa serum levels in a cohort of patients with type 2 diabetes (T2D) and severe soft tissue infections (STI), with severity and mortality factors. METHODS: A. comparative and transversal, study with 15 adult patients, any gender, with T2D and STI were done. A T2D control group of 20 patients without STI was included. Apache II Score, glycemia and by ELISA, IL6, IL10 and TNFa, were determined. RESULTS: in all patients, it was a correlation at beginning between glycemia and IL6 (r = 0.67, IC 95 % 0.24-0.88), as soon as glycemia and Apache II, (r = 0.59, IC 95 % 0.11-0.83). CONCLUSIONS: although IL6 was very usefulness, it is not a routine test in clinical laboratory and it is expensive, but in medical practice, it could be possible to evaluate these patients with Apache II Score and glycemia. However, in STI, the values of IL6 and IL10 were highly significant. It is likely that IL6 is a marker of poor outcome.

Tumor necrosis factor -308 and lymphotoxin +252 polymorphisms in Mexican children with Kawasaki disease and coronary aneurysms.

BACKGROUND AND AIMS: The Mexican population has a distinct capacity for the expression of tumor necrosis factor (TNF), a cytokine that plays a cardinal role in Kawasaki disease (KD), particularly in those who develop coronary aneurysms. It is important to identify, in Mexican pediatric patients, the association of the frequency of TNF. This study determined the association of TNF -308 and lymphotoxin-alpha (LTA) +252 polymorphisms in Mexican pediatric patients with KD and coronary aneurysms (CA). METHODS: We conducted a cross-sectional, analytical study in 48 children with KD, 22 with CA. Control samples were obtained from 61 aged-matched children. We took a peripheral blood sample and extracted genomic DNA from all children participating in the study. Using restriction factor length polymorphism-polymerase chain reaction (RFLP-PCR), we performed determination of TNF -308 and LTA +252. RESULTS: There was no difference in frequency between the study groups for genotype LTA +252 (OR 0.37, 95% CI, 0.06-2, p = 0.44) or between groups for KD with or without coronary aneurysms for both polymorphisms. In subjects with KD, we did not observe the heterozygous genotype of TNF -308, the difference being significant (OR 12, 95% CI, 4.8-30.4, p = 0.0001) using the χ(2) test with the continuity correction on comparison with the control group. CONCLUSIONS: Comparative analysis by group did not show a significant difference in the frequency of the alleles and genotypes between KD with CA vs. KD without CA vs. controls, for both TNF -308 and LTA +252.
