RESUMO
INTRODUCTION: Hepatitis virus C (HCV) infection is considered a health problem in the State of Acre localized in the Brazilian Amazon which has a prevalence rate of 5.9%. Peripheral neuropathy is a common extra-hepatic manifestation in patients with HCV. OBJECTIVE: To determine the prevalence of peripheral neuropathies using clinical and neurophysiological parameters. METHOD: A cross sectional study was performed in patients assisted by a specialized center of infectious diseases in the State of Acre. All patients completed a clinicoepidemiological questionnaire, physical examination and nerve conduction studies (NCS). RESULTS: We studied 78 patients with mean age 45.5 years (range from 10 to 76 years), two thirds were male, 51% had at least 8 years of formal education and 96% lived in the capital city of Acre State. Roughly 34% of patients complained about paresthesias mainly in upper limbs. The NCS diagnosed multiple mononeuropathy in 11 (14.1%; IC95% 7.6-23.2) patients and carpal tunnel syndrome in 4 (5.1%) patients. CONCLUSION: Subclinical involvement of peripheral nerves seems common in patients with HCV, with multiple mononeuropathy the main manifestation of nerve injury in this region as suggested by electrophysiological studies.

INTRODUÇÃO: A infecção pelo vírus da hepatite C (VHC) é considerada um problema de saúde pública no Estado do Acre com uma prevalência de 5,9 por cento. Neuropatia periférica é uma manifestação extra-hepática comum em pacientes com VHC. OBJETIVO: Determinar a prevalência de neuropatias periféricas através de parâmetros clínicos e neurofisiológicos. MÉTODO: Foi realizado estudo transversal em pacientes atendidos em uma clínica especializada de doenças infecciosas do Estado do Acre. Todos os pacientes foram submetidos a um questionário clínico-epidemiológico, exame físico e eletroneuromiografia (ENMG). RESULTADOS: Foram estudados 78 pacientes, com idade média de 45,5 anos (10 a 76), dois terços eram do sexo masculino, 51 por cento tinha pelo menos 8 anos de educação formal e 95 por cento moravam na capital do Estado. Aproximadamente 34 por cento dos pacientes se queixaram de parestesias, principalmente nos membros superiores. A ENMG diagnosticou mononeuropatia múltipla em 11 (14,1 por cento, IC95 por cento 7,6-23,2) pacientes e síndrome do túnel do carpo em 4 (5,1 por cento). CONCLUSÃO: Comprometimento dos nervos periféricos é comum em pacientes com VHC, sendo neuropatia múltipla a apresentação mais comumente diagnosticada pela ENMG.
