Frequencies of hepatitis B, delta and HTLV-III virus markers in Saudi Arabia.
Serum samples from 608 residents of Saudi Arabia were examined for the presence of hepatitis B, delta and HTLV-III virus markers. The HBsAg carrier rate was 17% and the prevalence of all hepatitis B virus markers was 55%. Males between 16 and 25 years had a significantly higher prevalence of all HBV markers (69%; 95% confidence limits: 49%-82%) compared to females in the same age group (34%; 95% confidence limits: 25%-45%). The prevalence of HBsAg was significantly higher among males aged 25-35 years (24%; 95% confidence limits: 19%-40%) compared to females in the same age group (9%; 95% confidence limits: 4%-18%). In addition, the HBsAg carrier rate for all males (23%) was significantly higher compared to females (11%) (p less than 0.001). HBeAg was found in 12% of 89 HBsAg-positive individuals, 48% were anti-HBe positive and 40% were negative for both markers. Hepatitis B virus DNA was found in 11 of 41 individuals tested. Five of these were HBeAg positive and four were anti-HBe positive. Anti-delta was found in three of 36 HBsAg positive serum samples (8%). Of 485 individuals tested for anti-HTLV-III, none were positive.
