A coinfecção do vírus da hepatite C (HCV) em pessoas portadoras do vírus da imunodeficiência humana (HIV) é freqüentemente observada em virtude destes vírus apresentarem similaridade em suas rotas de transmissão, principalmente no que se refere à via parenteral. No Brasil, a prevalência depende da área geográfica considerada, variando de 8,9% a 54%. Nos coinfectados, a progressão da doença pelo HCV é usualmente mais agressiva e apresenta alto nível de viremia, como também, há um risco maior de associação do HCV com a cirrose hepática e/ou hepatocarcinoma. O objetivo do presente estudo foi estimar a prevalência de HCV e fatores de risco associados à coinfecção em pessoas soropositivas para HIV na cidade de Imperatriz Maranhão. Participaram 249 pacientes soropositivos para HIV atendidos no SAE do Programa Municipal de DST/AIDS de Imperatriz do Maranhão. Foi coletado de cada voluntário 10 mL de sangue periférico para realização do teste sorológico, onde foi realizada pesquisa de anticorpos IgG HCV específicos e testes de Biologia Molecular (RT-PCR) para pesquisa do RNA viral e genotipagem. Entre os pacientes observou-se similaridade entre a frequência dos gêneros, 49% masculino e 51% feminino, com média de idade de 40 anos. Foi observado que 98% possuem baixo nível de instrução e 63% possuem renda mensal de até um salário mínimo. A soroprevalência do anti-HCV foi de 2.4% (6/249). Na comparação dos fatores de risco pesquisados entre os pacientes reagentes e não reagentes na pesquisa sorológica de anticorpos HCV específicas demonstraram que a presença de tatuagens e piercing foi o único fator que se mostrou significantes, sendo mais frequente nos reagentes. Esse foi o primeiro estudo que investiga a coinfecção HIV e HCV na cidade de Imperatriz, Maranhão e a identificação de pacientes coinfectados foi de fundamental importância para o serviço que a partir de então irá realizar o acompanhamento destes pacientes.

Infection with hepatitis C virus (HCV) is a worldwide problem of public health and who estimates 2.5% to 4.9% of infection by this virus among the population. This means that there are 3.9 to 7.6 million people at risk of developing cirrhosis or liver cancer. In Brazil, 20% to 58% of patients with chronic liver disease have antibodies to HCV (anti-HCV). To characterize the profile of patients undergoing treatment for hepatitis C in the Ambulatory General HC-FMB/UNESP, identify aspects of the disease and the phases of nursing process addressed during consultation. Transverse and descriptive study involving 38 patients undergoing treatment for Hepatitis C in Ambulatory General Area (Viral Hepatitis) in the period from July to September 2010. The population consisted of 38 patients, most of the males with completed higher education level, Catholic, married and aged predominantly between 41 and 60 years. Among the drugs used, we find the use of antihypertensive, antidepressant / anxiolytic and antidiabetic / hypoglycemic. With respect to specific medications used to treat hepatitis C, we found the use mainly of alfapeguinterferona 2b + ribavirin. The drugs used were complementary erythropoietin and filgastrim. There was a predominance of fibrosis 2 (F2) and genotype 1 (G1). Regarding the means of contamination, it was stressed blood transfusion and injection drug use. The most frequent drug reactions were decreased appetite, weight loss and discouragement. : The Nursing Process is considered a valuable tool in caring for patients with hepatitis C, because it works as identifying aspects of lifestyle, needs and potential of these patients and allows the deployment of humanized care strategies aimed at reduction of health hazards and improving the quality of life of these patients

Infection with hepatitis C virus is a worldwide public health problem it affects about 170 to 250 million people worldwide may lead to complications such as cirrhosis and hepatocellular carcinoma. Patients with chronic hepatitis C most often is inadequate nutrient intake, macro and micronutrients, which induces changes in nutritional status and lipid profi le. Supplementation with vitamin C has shown benefi t. Limited information is available on levels of vitamin C in this type of illness. The study aimed to evaluate the effect of regular intake of orange juice on the nutritional and dietetic of patients with chronic hepatitis C infection. The study enrolled 23 patients volunteers, 13 men and 10 women treated at the Special Health Service of Araraquara (SESA). They consumed for 8 weeks 500 mL.d-1 of pasteurized orange juice. At baseline and after 8 weeks of juice intake the patients were evaluated for anthropometric parameters. The dietary intervention with 500 mL.d-1 with orange juice during the 8 weeks did not alter the nutritional status of patients.

The real role of renal transplantation in hepatic fi brosis progression caused by hepatitis C virus is still unpredictable. Histological evaluation of the liver is the best form to estimate fi brosis evolution, although semiquantitative analysis carries important limitations. Objective: To apply a morphometric quantitative assay on hepatic fi brosis progression in renal recipients with hepatits C. Methods: Thirty patients were initially evaluated, but only seven were included. They underwent the fi rst biopsy near the transplantation date and the second biopsy at least 4 years later. The immunosuppressant therapy adopted in all cases was azatioprine and micofenolate. Fibrosis progression rate (FPR) was calculated before and after the surgery date in each patient according to Metavir score and morphometric analysis. Results: The FPR calculated by Metavir score showed no statistical difference between pre- and post-transplantation (p=0.9). The FPR calculated by the morphometric analysis was 0.58 ± 0.78 before transplantation and 3.0 ± 3.3 after the surgery, with statistical signi- fi cance between these values (p=0.0026). Conclusion: In the sample assessed, the progression of hepatic fi brosis was documented and quantifi ed only by the morphometric analysis, which is as a promising approach to histological evaluation of these patients.
