Prevalence of hepatitis B and hepatitis C in haemodialysis patients

Nephrology (1998)

M I dos Santos Romina S. Danguilan E. Que Rene P BALMACEDA Benita Padilla

The prevalence of hepatitis B surface antigen (HBsAg), hepatitis B exposure and antibodies against the hepatitis C virus (anti‐HCV) was assessed in 86 haemodialysis patients at the National Kidney and Transplant Institute (NKTI) using the commercial radioimmunoassay and ortho HCV ELISA assay. Of the 86 patients included in the study, 42 were male with a mean age of 44.9 years and a mean duration of dialysis of 2.4 years. Forty‐four were female with a mean age of 48.4 years and a mean duration of dialysis of 2.3 years. Hepatitis B exposure was 57% and 12.8% of haemodialysis patients were positive for HBsAg, whereas 39.8% of patients were positive for anti‐HCV. There was a significant correlation ( P =0.00007) between anti‐HCV positivity and the length of time on haemodialysis. However, there was no significant correlation found between the number of blood transfusions received and anti‐HCV positivity. There was also no significant correlation found between HBsAg and antibodies to hepatitis B core antigen (anti‐HBc) positivity and the number of blood transfusions or the length of time on haemodialysis, nor between hepatitis B and C exposure and elevated aminotransferase levels.

During the period February 1987-June 1988, we examined 542 stool samples of 271 HIV positive patients both with and without full-blown AIDS. One hundred patients with either acute or chronic diarrhea and 180 patients without diarrhea were studied. The stool samples were examined for the presence of Cryptosporidium sp., other protozoa, helmints, and pathogenic enterobacteria. We found a prevalence of 14.3% of Cryptosporidium sp. in patients with full-blown disease and diarrhea. We encountered no Cryptosporidium sp. among asymptomatic patients. The occurrence of diarrhea was significantly associated with a CD4/CD8 ratio lower than 0.4, with the finding of Cryptosporidium sp. in the stools, being a CDC group IV, and with a positive stool culture for pathogenic enterobacteria. The diarrhea caused by Cryptosporidium sp. could not be distinguished, on clinical grounds, from diarrhea caused by other etiologic agents.During the period February 1987-June 1988, the authors examined 542 stool samples of 271 HIV-positive patients both with and without fullblown AIDS. 100 patients with either acute or chronic diarrhea and 180 without diarrhea were studied.
