RESUMO Objetivo A investigação do perfil inflamatório sistêmico de pacientes acometidos por câncer de próstata (CaP) ou hiperplasia prostática (HPB) pode contribuir para caracterizar o perfil patológico, bem como possibilitar a identificação de marcadores e promover alternativas de tratamentos adequados e menos invasivos. Métodos Esta pesquisa comparou os níveis séricos de 10 mediadores inflamatórios clássicos em pacientes com 50 anos ou mais afetados por CaP ou HPB. Para tanto, foram considerados os aspectos clínicos, bioquímicos, metabólicos, antropométricos e inflamatórios de cada paciente. Resultados A partir da análise estatística, foi encontrada umacorrelação positiva fraca (r = 0,16) entre IL-2 com os valores de PSA total sé o. Além disso, os valores medianos de IL-2 no soro foram três vezes maiores em pacientes com CaP em comparação com pacientes com HPB. Conclusão Pela interpretação da literatura atual, hipotetizamos que a atividade de macrófagos do tipo M1 infiltrados e células citotóxicas ativadas no meio da neoplasia pode explicar esse aumento de IL-2 como parte de uma resposta antineoplásica endógena.

ABSTRACT Objective Investigation onthe systemic inflammatory profile ofpatients affected by prostate cancer (PCa) or prostatic hyperplasia (BPH) may contribute to characterize the pathological profile as well as enable identification of markers and promote alternatives for appropriate, less invasive treatments. Methods This research compared serum levels of 10 classic inflammatory mediators among patients aged 50 years or older affected by PCa or BPH. For this, clinical, biochemical, metabolic, anthropometric and inflammatory aspects of each patient was considered. Results From the statistical analysis, a weakpositive correlation (r = 0.16) between IL-2 with serum total PSA values was found. In addition, median serum IL-2 values were three times higher in patients with PCa compared to BPH patients. Conclusion By interpretation of current literature, we hypothesize that the activity of infiltratedtype M1 macrophages and activated cytotoxic cells in the neoplasm milieu might explain this increase of IL-2 as part of anendogenous anti-neoplastic response.

SUMMARY INTRODUCTION: The impact of type 2 diabetes mellitus raises interest in understanding its evolutionary-genetic basis, to unveil yet unknown pathways that may have immediate medical relevance. The HNF1β gene (hepatocyte nuclear factor-1 beta) is a transcription factor expressed in tissues such as liver, kidney, genital tract and pancreas that is known to be essential for insulin secretion and glucose balance. We tested the association of allelic variants produced by the HNF1β gene (rs4430796) variation with the clinical and biochemical profile of elderly Brazilian outpatients with metabolic disorders. MATERIAL AND METHODS: Anthropometry, blood pressure, glycaemia, lipemia and other parameters were assessed in 184 Brazilians aged 60 or older in clinical care settings. Alleles were determined by amplification of the polymorphic site by real time polymerase chain reaction. RESULTS: Analysing variables across the genotypes, a statistically significant difference was noticed in the allele frequencies among diabetic patients, with 30.8% of the A homozygous bearing the condition compared to a prevalence of 12.2% between G homozygotes. CONCLUSION: Our results corroborate the possible protective property of the GG genotype from the rs4430796 variation (already presented in the literature) against occurrence of diabetes mellitus, which appears applicable to elderly individuals as well, even in the context of multiple metabolic disorders so typical in older Brazilians.
