Coinfection with hepatitis viruses and human immunodeficiency virus in multiply transfused patients.

The prevalence, clinical manifestations and serological markers of hepatitis C virus (HCV), hepatitis B virus (HBV) and human immunodeficiency virus (HIV) infections were studied in 112 multiply transfused patients (49 hemophiliacs receiving either nonheat-treated factor concentrates or cryoprecipitate, 33 thalassemic, 20 refractory anemia and 10 leukemia patients). Positive serological markers for HCV, HBV and HIV were found to correlate with number of donors and duration of disease (logistic regression P = 0.0001 and 0.01 respectively). Viral infectivity was significantly correlated with type of blood product. HCV seropositivity was more common in hemophiliacs treated with nonheat-treated factor concentrates (93%) compared to those receiving cryoprecipitate (37%) or nonhemophiliacs receiving red packed cells (20%) (P < 0.001). Likewise, HBV seropositivity in patients receiving the above blood products was 83%, 61% and 26% respectively (P < 0.001), and HIV seropositivity was 35%, 6% and 0% respectively (P < 0.001). Acute or chronic liver disease was documented in 4 of 14 (28%) HCV-positive patients. Increased liver enzymes were recorded in sera of 43% HCV-positive patients and 18% HBV-positive patients compared to 22% of HBV and 20% HCV-seronegative patients (P = 0.076). Of 47 HCV-positive patients 24 were coinfected by HBV and 9 had triple infection (HCV, HBV and HIV). No solitary HIV infection was found. HIV seropositivity was always accompanied by serologic evidence for HBV with or without HCV infection.
