ABSTRACT

Abstract Hepatitis C is a worldwide endemic disease. However, hepatitis C virus genotype 4 (HCV GT-4) has rarely been reported in Brazil. HCV GT-4 demonstrates high sustained virological response (SVR). Here, we report the case of a 62-year-old HCV GT-4 positive woman complaining of a headache, nausea, and arthralgia. The patient was treated according to the protocol for genotype 4 (12 weeks administration of 400mg sofosbuvir and 60mg daclatasvir daily) and achieved SVR. Although this is not an Amazonas autochthonous case, the presence of genotype 4 is rarely reported in the region.

ABSTRACT

The association of HIV infection and hepatitis C virus (HCV) infection often occurs because both viruses share the same transmission routes, increasing the possibility of HIV/HCV coinfection. World prevalence greater than 30 percent of coinfected cases is estimated, and it can reach 90 percent depending on the transmission route. With the aim of determining the frequency and profile of HIV/HCV coinfected patients, a descriptive analysis was carried out with patients with HIV/AIDS whose serology was positive for hepatitis C virus (HCV), cared for at the Fundação de Medicina Tropical do Amazonas from 2000 to 2007. In the present study, of the 2,653 AIDS cases notified in SINAN, 1,582 patients underwent serology test for hepatitis C, and a frequency of 4.42 percent (n = 70) of HIV/HCV coinfected patients was identified in the period studied. The most frequent infection route was sexual transmission (84.3 percent), 68.6 percent among heterosexual individuals. Most patients were males (72.9 percent), aged between 25 and 40 years (60.1 percent), of low income (50 percent earning up to one minimum wage), and low educational level (80 percent had completed only middle school). A high percentage of deaths were observed during the study (34.3 percent). The results indicate a low seroprevalence of HIV/HCV coinfection in this population, in which sexual transmission, characterized by sexual promiscuity among heterosexual individuals, is the major transmission route of the virus rather than the use of injection drugs, as shown in world statistics.

ABSTRACT

The present study was conducted with 55 patients native from western Brazilian Amazonia, who were HBV-DNA positive after seroconversion of HBeAg. It is a descriptive case study, with the patients separated into two groups: with hepatitis and without hepatitis on histological examination. The aim of the present study was to describe the clinical and molecular characteristics of patients who are chronic carriers of HBsAg. The prevalence of hepatitis was 63.64 percent, with a predominance of males (41.82 percent) and a mean age of 42.5 years, occurring mostly in natives of the southeast sub-region (32.73 percent). Time was a variable proportional to the course of the disease and the most frequent symptoms were: dyspepsia, asthenia and loss of libido with the majority of the patients having history of prior contact with HBV or positive family history. Splenomegalia was the most frequent sign (40 percent). Among the tests, platelet count, serum albumin and prothrombin activity were significant in the diagnosis of hepatitis. Alpha-fetoprotein was greater in patients with hepatitis, and hepatocellular carcinoma was detected in 3.63 percent of the patients with hepatic cirrhosis. Three types of HBV genotypes were diagnosed: A, D and F in the samples amplified for gene S. Genotype A (AA) was observed in 54.54 percent of the cases with hepatitis, in contrast to other studies showing the predominance of genotype F in this region. We observed mutations in 36.36 percent, with a predominance of the mutations in the core promoter region (31.81 percent), due to the greater prevalence of genotype A in this study.
