Antibody to Hepatitis A Antigen in Institutionalized Mentally Retarded Patients

Prevalence of hepatitis A antibody among disadvantaged gypsy children in northern Spain

“…In most developed countries, the prevalence of hepatitis A is higher in the most disadvantaged groups and the prevalence of HAV antibodies increases at lower income levels [10]. We are not aware of any studies of the prevalence of HAV infection among gypsies, but the gypsies in Spain are a socially and economically disadvantaged group of people and hepatitis A is known to be more common among population groups with low standards of hygiene, such as intravenous drug users and the mentally retarded [1,11,12]. The results of our study probably can be extrapolated to other similarly disadvantaged population groups in Spain, both gypsies and non-gypsies.…”

Seroprevalence of hepatitis E virus infection among institutionalized psychiatric patients in Taiwan

“…Institutionalized patients are at high risk of suffering from infectious diseases, such as hepatitis A (Szmuness et al, 1977) and B (Koplan et al, 1978;Krugman et al, 1979). Among psychiatric patients, mongoloid patients often become hepatitis B surface antigen (HBsAg) carriers (Sutnick et al, 1972).…”

Prevalence of Hepatitis B in an Adult Psychiatric Hospital

“…The results of this study have indicated the prevalence of hepatitis B virus in the patients of a psychiatric center to be higher than prevalences in healthy blood donors 5 and the general adult population of the United States, 6 but lower than those in “high‐risk” groups such as the residents of schools for the mentally retarded, 7 male homosexuals, 8 patients and staffs of hemodialysis units, 9 and certain ethnic groups from other parts of the world 10 . It was closely similar to the rates for HBsAg and anti‐HBs as determined in a survey of physicians in attendance at three AMA conventions.”…”
