ABSTRACT

Since humans rarely play the role as Echinococcus oligarthrus host, there is lack of knowledge about the complex infectious process. Only three cases have been reported to occur in humans in the neotropics until now. We present the anatomo-clinical and molecular findings describing a new case of infection by E. oligarthrus in a man. The muscular or subcutaneous tissues tropism described for this species in the previously reported cases was not present, but a liver tropism was observed. Additionally, the larval stage rostellar hooks morphometry differed from E. oligarthrus in the other human cases.

ABSTRACT

INTRODUÇÃO: Com o advento da terapia antirretroviral de alta atividade em 1996, a doença hepática tornou-se causa importante de morbidade e mortalidade em pessoas infectadas pelo vírus da imunodeficiência humana-1 (HIV-1). OBJETIVO: Descrever os aspectos demográficos e laboratoriais de 62 pacientes coinfectados com o vírus da imunodeficiência humana e da hepatite C (HIV-1/HCV). MÉTODO: Estudo transversal, incluindo pacientes portadores do HIV, confirmados sorologicamente (ELISA + Imunofluorescência indireta ou Western Blot), com anti-HCV positivos pelo teste de ELISA confirmados por RT-PCR, atendidos no ambulatório de fígado da Fundação Santa Casa de Misericórdia do Pará no período de agosto de 2004 até abril de 2008. RESULTADOS: Foram atendidos 49 (79 por cento) indivíduos do gênero masculino e 13 indivíduos do gênero feminino, com mediana de idade de 42,6 anos, solteiros (66, por cento. n = 41), heterossexuais (59,7 por cento, n = 37), bissexuais (27,4 por cento, n = 17), homem que faz sexo com homem HSH (12,9 por cento. n = 8); contagem de linfócitos T CD4+ com mediana de 327 células/mm3, carga viral plasmática do HIV com mediana de 2,54 log10 HIV-RNA cópias/mL, carga viral do HCV (HCV-RNA) de 5,90 log10 UI/mL. O genótipo 1 do HCV foi encontrado em 60,87 por cento. A biópsia hepática foi realizada em 41 (66,12 por cento) pacientes, tendo sido observada a seguinte classificação METAVIR: F0 (12 por cento), F1 (24,4 por cento), F2 (32 por cento), F3 (17 por cento) e F4 (14,6 por cento). CONCLUSÃO: Os pacientes eram predominantemente solteiros,com carga viral do HCV elevada, apresentavam fibrose de moderada a severa em mais de 50 por cento dos casos sem alterações laboratoriais significativas...


INTRODUCTION: Since highly active antiretroviral therapy was developed in 1996, liver injury has become an important cause of morbidity and mortality in individuals infected by the human immunodeficiency virus-1 (HIV-1). OBJECTIVE: To report the demographic and laboratory findings of 62 patients coinfected with HIV-1/HCV. METHODS: This cross-sectional study analyzed HIV patients, confirmed serologically by ELISA and indirect immunofluorescence or Western Blot, with positive anti-HCV by ELISA and confirmed by RT-PCR. These patiens were treated at the Liver Department of the Fundação Santa Casa de Misericórdia do Pará from August 2004 to April 2008. RESULTS: A total of 49 (79 per cent) male and 13 female patients were analyzed. Their age median was 42.6 years and they were single (66.1 per cent n=41), heterosexual (59.7 per cent, n = 37), bisexual (27.4 per cent, n = 17), man who have sex with man MSM (12.9 per cent, n = 8); the lymphocytes T CD4+ count median was 327 cells/mm3, HIV serum viral load median was 2.54 log10 HIV RNA copies/mL, HCV viral load (RNA-HCV) was 5.9 log10 UI/mL. The HCV genotype 1 was found in 60.87 per cent of the patients. Forty-one (66.12 per cent) patients were submitted to liver biopsies and the histopathology results according to METAVIR were F0 (12 per cent), F1 (24.4 per cent), F3 (17 per cent), F4 (14.6 per cent). CONCLUSION: Patients were predominantly single, with high viral load. They presented with moderate to severe fibrosis in more than 50 per cet of cases without significant changes in their laboratory findings...

ABSTRACT

O Município de Juruti, localizado a oeste do Estado do Pará, possui importante reserva de bauxita, cuja exploração iniciou em 2005. O surgimento ou aumento da frequência de doenças influenciadas por essa exploração, particularmente em relação às hepatites virais, é diversa da observada em qualquer outra região do mundo. Para definir a prevalência das infecções pelos vírus das hepatites A, B, C e D na demanda do hospital municipal de Juruti, entre fevereiro de 2007 e abril de 2008, foram coletadas amostras de soro de pessoas da demanda hospitalar e submetidas à análise dos marcadores sorológicos das hepatites A (VHA), B (VHB), C (VHC) e D (VHD), por técnicas imunoenzimáticas. Nas amostras positivas para os vírus B e C foram realizadas pesquisas para detecção do VHB-DNA e VHC-RNA, por PCR e RT-PCR, respectivamente. Entre as 1.630 amostras coletadas, ocorreu prevalência de 85,6 por cento para o anti-VHA total; de 0,7 por cento para o HBsAg; 9,1 por cento anti-HBc/anti-HBs e 31,4 por cento anti-HBs isolado. Entre os HBsAg+, 9,1 por cento eram HBeAg+; 63,6 por cento anti-HBe+ e 72,7 por cento VHB-DNA+. O anti-VHC foi positivo em 0,1 por cento e não foi detectada sorologia positiva para o VHD. Caracterizamos, em base laboratorial, alta prevalência de infecção pelo VHA, detecção de portadores crônicos e de suscetíveis para o VHB, presença de portador do VHC e a ausência de portadores do VHD. Recomenda-se a realização de estudos epidemiológicos locais, baseados em comunidades, para comparar com os dados hospitalares ora apresentados...


The Juruti Municipality, located to the west of the Pará State, possesses major bauxite reserves, the exploration of which started in 2005. The appearance of some diseases and the increased frequency of others have been influenced by this exploration, particularly in relation to viral hepatitis. These epidemiological trends are different from those observed anywhere else worldwide. To define the prevalence of the infections by the hepatitis A, B, C and D viruses in the Juruti municipal hospital between February 2007 and April 2008, serum samples were collected from patients and analyzed for serological markers of hepatitis A (HAV), B (HBV), C (HCV) and D (HDV) by immunoenzymatic techniques. In samples positive for the hepatitis B and C viruses, assays were performed for the detection of HBV-DNA and HCV-RNA by PCR and RT-PCR, respectively. Among the 1,630 samples collected, the prevalence of total anti-HAV was 85.6 per cent; HBsAg was 0.7 per cent; anti-HBc/anti-HBs was 9.1 per cent and isolated anti-HBs were 31.4 per cent. Among the HBsAg+, 9.1 per cent were HBeAg+; 63.6 per cent were anti-HBe+ and 72.7 per cent were HBV-DNA+. Anti-HCV was positive in 0.1 per cent of the samples and positive serologies were not detected for HDV Laboratory-based characterization revealed a high prevalence of infection by HAV, detected chronic HBV carriers and those susceptible to HBV, identified an HCV carrier and revealed the absence of HDV carriers. Local, community-based epidemiological studies are recommended for comparison to the hospital data presented here...

ABSTRACT

Objetivo: avaliar a carga viral do vírus da Hepatite C (HCV-RNA) em pacientes co-infectados pelo vírus HIV/ HCV e comparar os achados com a carga viral de pacientes monoinfectados com o HCV. Método: realizado estudo transversal, com casuística de 45 pacientes portadores da co-infecção HIV-1/HCV e 100 pacientes monoinfectados com HCV, atendidos no Programa de Hepatopatias do Ambulatório do Fígado do Hospital da Fundação Santa Casa de Misericórdia do Pará (FSCMPA), período de abril de 2007 a abril de 2008. Resultados: os níveis encontrados da carga viral do HCV-RNA no grupo de co-infectados foram de 850000.000 UI/mL e nos pacientes monoinfectados 480622.000, p<.005. Conclusão: os níveis de RNA HCV são maiores no grupo de co-infectados.
