The prevalence of hepatitis delta virus (HDV) infection was studied in 140 unselected intravenous drug addicts whose sera were drawn between 1985 and 1986 and in 100 addicts from whom sera were obtained between 1988 and 1989. It was observed that 1.8% of those positive for hepatitis B virus (HBV) markers from the earlier period and 23.2% of those from the(More)
We studied 100 unselected parenteral drug abusers for infection with hepatitis C, B, A and D virus (HCV, HBV, HAV and HDV). Seventy-six percent had serological evidence of HCV infection. 12% were positive for HBsAg and at least one marker of HBV infection was present in 69%. These results were significantly higher than in a matched control population.(More)
The prevalence of HCV, HBV and HAV markers was investigated in unselected patients attending an outpatient alcoholic clinic. Anti-HCV were detected in 35 (24%) of 144 patients studied, and at least one marker of HBV infection was present in 72 (50%). These results are significantly higher than in a matched control population. The presence of anti-HCV was(More)
To assess the epidemiology of hepatitis C virus (HCV) in Poland, anti-HCV was studied in patients with acute and chronic non-A, non-B (NANB) hepatitis, in healthy adults, and in subjects at risk. Anti-HCV prevalence was 2% in 152 blood donors, 78% in 95 parenteral drug addicts, 21% in 112 alcoholics, and 86% in 42 patients with chronic NANB hepatitis. Among(More)
Prevalence of HAV infection markers was studied in 100 drug addicts whose sera were collected between 1988 and 1989. Anti-HAV antibodies were found in 65 (65%) of the tested drug addicts and in 55% of the individuals serving as the control group. No correlation between the presence of HAV infection markers, and sex, duration of drug abuse or HIV status was(More)
Prevalence of markers of HBV infection was tested in two cohorts of drug addicts: in 140 addicts whose sera were drawn in the years 1985-1986 and in 100 addicts whose sera were drawn in the years 1988-1989. HBsAg was found in 10 (7%) patients in the earlier cohort and in 12 (12%) addicts in the latter, while at least one marker of HBV infection was present(More)
The prevalence of anti-HCV and serological markers of HBV infection was tested in 100 unselected intravenous drug addicts admitted to a detoxification ward. Anti-HCV were present in 78% addicts, and at least one markers of HBV infection was present in 69% addicts. No correlation was found between anti-HCV status and age, gender, duration of addiction or(More)
Among 530 consecutive patients hospitalized for acute hepatitis in the years 1986-1988 cytomegalovirus infection was diagnosed in 5 (0.9%). All 5 patients had symptomatic hepatitis with jaundice, 3 had pruritus. Hematological changes were relatively mild and liver function tests were not essentially different from those found in patients with hepatitis A,(More)
