BACKGROUND
While 20-40% of patients with hepatitis C virus (HCV) monoinfection will spontaneously clear the virus, less is known regarding clearance with coinfections. HCV, human immunodeficiency virus (HIV), and human T-cell lymphotrophic virus 1 and 2 (HTLV-1/2) coinfection occurs due to shared
The artificially acquired humoral immunity against hepatitis B virus (HBV) apparently may decline over the years. This study aimed to investigate the prevalence of naturally occurring serological markers of infection and active immunity to HBV in severely ill children and adolescents treated at the
Background: The heterogeneity in detection rates of human immunodeficiency virus (HIV), human T-lymphotropic virus (HTLV) and hepatitis B and C infections among pregnant women and the continuous exposure to risk factors limits the adoption of preventive and control
A case of a four-year-old boy from Salvador, Bahia, Brazil, with a probable Lábrea hepatitis is reported. He ran a rapid course of fever, jaundice, abdominal pain, agitation, coma and death. Histologically, the liver presented widespread hepatic cell lytic and coagulative necrosis, acute fatty
Hepatitis C virus displays a high degree of genetic mutation, with considerable heterogeneity, motivating clinical and biomolecular investigations. It is necessary to understand the effects of genotypes on the course of the disease, as well as their peculiarities at the regional level.
OBJECTIVE
The
In Cavunge community, a rural village of the dry tropic in Bahia State, Brazil, a sentinel study on viral hepatitis was developed to characterize the seroprevalence of hepatitis A. The presence of IgG anti-HAV was analyzed in 891 citizens and 85.9% were positive. The prevalence was similar between
BACKGROUND AND RATIONALE FOR THE STUDY: Hepatitis B (HB) is one of the most prevalent occupational infections in health attendance environments. According to the Brazil Ministry of Health, health professionals must be vaccinated against the hepatitis B virus (HBV) and provide laboratory proof of
Both Human T-lymphotropic virus type 1 (HTLV-1) and hepatitis C virus (HCV) are endemic in Brazil. In Salvador, the capital of the state of Bahia, 2% and 1.5% of the general population is infected with HTLV-1 or HCV. This study aimed to estimate the prevalence and the distribution of HTLV/HCV
Hepatitis E virus (HEV) is prevalent in Asia and Africa. Recently, it was also described in Mexico, but epidemiologic data from other Latin American countries are scarce. The seroprevalence of anti-HEV in a referral hepatology unit in northern Brazil was determined by testing for anti-HEV IgG in 701
The objective of the present study was to analyze HCV serological and virological parameters from hemophiliacs in the State of Bahia. Anti-HCV was investigated by ELISA in a cohort of 268 hemophiliacs A/B who were followed-up in a reference unit for hemotherapy in the State of Bahia. HCV viremia and
OBJECTIVE
To determine the prevalence of liver changes in workers at an oil refinery located in the state of Bahia, Brazil, as compared to a reference population with no occupational exposure to chemical products, and to describe the factors associated with the observed differences in
OBJECTIVE
To report demographic and clinical characteristics of patients with asthma who evolved to death, as well as to describe the conditions related to this outcome in a subgroup of patients admitted to the Program for the Control of Asthma and Rhinitis in Bahia (ProAR).
METHODS
A descriptive,
Generation of epidemiological data on perinatally-transmitted infections is a fundamental tool for the formulation of health policies. In Brazil, this information is scarce, particularly in Northeast, the poorest region of the country. In order to gain some insights of the problem we studied the
The serological screening of blood donors has been instituted by the Brazilian Ministry of Health and is mandatory in the research on several diseases transmissible through blood transfusion. Blood banks need to establish a screening service capable of reducing associated transfusions
