ABSTRACT

OBJECTIVES:

To determine the prevalence of insulin resistance (IR) in non-diabetic patients with chronic hepatitis C, and to assess the association between IR, laboratory parameters and histological findings. SUBJECTS AND

METHODS:

Eighty-two patients had their serum analyzed for glucose, lipid profile, C-reactive protein (CRP), ferritin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), HOMA-IR, viral load and HCV genotype. Patients with HOMA-IR levels > 2.5 were considered as carriers of insulin resistance.

RESULTS:

IR was observed in 27 percent of patients and was associated with age, waist circumference and body mass index. IR patients were more likely to have more advanced hepatic fibrosis and necroinflammatory activity, higher levels of aminotransferases and liver steatosis than patients without IR.

CONCLUSIONS:

Insulin resistance is often present in patients with chronic hepatitis C, and this parameter is associated with more advanced HCV-related hepatic fibrosis.
RESUMO

OBJETIVOS:

Em portadores de hepatite crônica C não diabéticos, verificar a prevalência de resistência insulínica (RI) e analisar a associação desta com os parâmetros laboratoriais e histológicos. SUJEITOS E

MÉTODOS:

Foram incluídos no estudo 82 pacientes, e amostras de sangue foram coletadas para determinação de glicose, perfil lipídico, alanina aminotransferase (ALT), aspartato aminotransferase (AST), ferritina, HOMA-IR, carga viral e genótipo do VHC. HOMA-IR superior a 2,5 foi considerado resistência insulínica.

RESULTADOS:

RI foi observada em 27 por cento dos pacientes e foi associada a idade, circunferência abdominal e índice de massa corpórea. Quando comparado a pacientes sem RI, aqueles com HOMA-IR superior a 2,5 apresentaram graus mais acentuados de fibrose hepática e atividade necroinflamatória, maiores níveis de aminotransferases e esteatose hepática mais frequente.

CONCLUSÕES:

É comum a presença de RI em portadores de hepatite crônica C e esta se associa com graus mais avançados de fibrose hepática induzida pelo vírus da hepatite C.
