Poor sensitivity of rapid tests for the detection of antibodies to the hepatiti...
Cruz, Helena Medina; Scalioni, Leticia de Paula; Paula, Vanessa Salete de; Miguel, Juliana Custódio; Ó, Kycia Maria Rodrigues doRapid tests (RTs) can be used as an alternative method for the conventional diagnosis of hepatitis B virus (HBV). This study aims to evaluate antibodies to HBsAg (anti-HBs) and antibodies to HBeAg (anti-HBe) RTs under different Brazilian settings. The following three groups were included: GI: viral hepatitis outpatient services; GII: low resource areas; and GIII: crack users and beauticians. Imuno-rápido anti-H...
Prevalence of Hepatitis B and C virus infection among alcoholic individuals: im...
Cortes, Vanessa Faria; Taveira, Angela; Cruz, Helena Medina; Reis, Amanda Alves; Cezar, Jéssica Silva; Silva, Brener SantosDrug users have been reported to have an increased risk for acquisition of viral hepatitis. This study aims to evaluate the prevalence of HBV and HCV infection and usefulness of saliva for HBsAg and anti-HCV detection in alcoholic patients.A total of 90 alcoholic patients were recruited in 2013. HBsAg and anti-HCV were tested in serum and saliva, anti-HBc and anti-HBs were tested in serum using commercial enzym...
