ROVIRA, C et al. Hepatitis B: surface antigen and post-vaccination antibodies in women from the Psychiatric Hospital of Asunción, Paraguay. Mem. Inst. Investig. Cienc. Salud [online]. 2011, vol.9, n.2, pp.57-63. ISSN 1812-9528.
ABSTRACT Hepatitis virus B is transmitted by various routes including blood, vertical and sexual routes. Patients with severe mental health conditions are at greatest risk of acquiring any viral infection such as hepatitis B, C and HIV. The length of the stay in mental institutions influences the spread of the diseases and long periods of stay increase the opportunity for viral transmission. The objective of this study was to know the frequency of the surface antigen of hepatitis B and determine the post-vaccination antibodies against hepatitis in women of reproductive age, hospitalized in a psychiatric hospital of the Ministry of Public Health and Social Welfare of Asunción, Paraguay. This was an observational descriptive study carried out from May 2008 to May 2010. We studied 72 female patients in childbearing age, from 18 to 49 years (mean 38 years ± 6). Sera were tested for HBsAg and post-vaccination anti-HBs by ELISA. Serological evidence of Hepatitis B virus infection was not found in the 72 patients. Twenty nine out of thirty patients who were administered 3 doses of vaccine had adequate protective values (greater than 20 mIU/mL) at two months after vaccination and one had a value less than 10 mIU/mL. With the response found in the study patients of this mental health institution, the complications of hepatitis B would be reduced and the horizontal transmission to other patients and health personnel of the institution would be prevented and specially the hepatitis B transmission to fetus in case of pregnancy.
