Background and Objectives: In Indian blood banks, screening for hepatitis B
virus (HBV) is currently done by the EIA method, but no routine screening
is done for hepatitis C virus (HCV). Materials and Methods: To determine th
e incidence of transfusion-associated HCV hepatitis, and of any residual tr
ansfusion-associated hepatitis (TAH) after HBsAg screening, we prospectivel
y studied 182 patients who underwent surgery and received blood transfusion
. These recipients had normal alanine aminotransferase (ALT) and were negat
ive for HBsAg (monoclonal EIA), and anti-HCV (third-generation EIA) before
receiving transfusion. Results: Of the 818 blood units transfused after rou
tine screening (average 4.49+/-3.3 U/patient, range 1-14), 14 (1.7% of unit
s) were found to be infected. Of the 182 recipients, 14 (7.69%) developed T
AH during a follow-up of 6 months, 3 (21.4%) from HBV, 10 (71.5%) from HCV,
and 1 (1.7%) from a coinfection of HBV and HCV. All patients with TAH due
to HCV were asymptomatic. One patient with TAH due to HBV (33%) and 5 with
TAH due to HCV (50%) developed chronic infection with persistently elevated
ALT at 6 months. Conclusions: With the current screening practices, the in
cidence of TAH remains high in India and is mainly due to HCV infection. Fu
rthermore, the screening methods for HBV also need to be improved. Material
