ABSTRACT

INTRODUÇÃO: No Estado do Amazonas, os dados sobre a prevalência dos genótipos do vírus da hepatite C ainda são escassos. MÉTODOS: Os genótipos do VHC foram determinados em 69 pacientes da Fundação de Medicina Tropical do Amazonas - FMT-AM. O RNA do VHC foi detectado pela técnica de RT-PCR, utilizando-se iniciadores HC11/HC18 para a região 5'não traduzida. RESULTADOS: Dos 69 pacientes, 65,2 por cento era do sexo masculino e 34,8 por cento do feminino. O genótipo 1 foi o mais prevalente, seguidos dos 3 e 2. CONCLUSÕES: Estes dados sugerem que Manaus é uma porta de entrada do vírus VHC no Estado do Amazonas.


INTRODUCTION: In the State of Amazonas, data regarding the prevalence of different genotypes of hepatitis C virus remains scarce. METHODS: The genotype of 69 HCV positive patients was determined. An in-house standardized nested-PCR was used to detect HCV RNA. Genotype assignment was based on type-specific motifs on the sequenced amplicons delimited by primers HC11/HC18 from the 5' untranslated region. RESULTS: Of the 69 patients studied, 65.2 percent were male and 34.8 percent were female. Genotype 1 showed the greatest prevalence, followed by 3 and 2. CONCLUSIONS: These data suggesting that Manaus is the point of arrival of HCV in the State of Amazonas.

ABSTRACT

Relata-se um paciente do sexo masculino com 67 anos e sorologia positiva para o vírus da hepatite C (HCV). Exames moleculares revelaram a presença do RNA do HCV, com carga viral de 2.000 cópias/mL e genótipos 1 e 2. O tratamento foi com alfapeginterferon-2a, 180mcg/semana e ribavirina, 1.000mg/dia. Na quarta semana de tratamento, a carga viral para o HCV era indetectável. Na nona semana, o paciente apresentou hematêmese, piora do quadro de astenia, inapetência e comprometimento do estado geral, quando o tratamento foi descontinuado. O PCR foi negativo após 6 meses e permaneceu assim após um ano. O paciente encontra-se assintomático.


A report of a 67 year-old male patient with positive serology for HCV. PCR revealed the presence of HCV RNA, viral load of 2,000 copies/mL and genotypes 1 and 2. The pacient was treated with peginterferon alfa-2a at 180mcg/week and ribavirin at 1,000mg/day. In week four of treatment, HCV viral load was undetectable. In week nine, the patient developed hematemesis, worsening of asthenia, anorexia and impaired general condition, so the treatment was discontinued. The PCR was negative six months and one year after the cessation of treatment. The patient remains asymptomatic.
