M. Aslam et J. Aslam, Seroprevalence of the antibody to hepatitis C in select groups in the Punjab region of Pakistan, J CLIN GAST, 33(5), 2001, pp. 407-411
Goals: Hepatitis C is on the rise in clinics in Pakistan. To estimate the o
ccurrence of hepatitis C in the region and to create awareness about the di
sease in the general public, two studies were conducted in Punjab, Pakistan
. Before this, no such effort has been made in Pakistan. Background: Two st
udies were held in Lahore and Gujranwala of Punjab, Pakistan. These studies
were advertised throughout the city, and people who participated were scre
ened for anti-hepatitis C virus (anti-HCV)-positive serology at a concessio
n rate and were surveyed through a questionnaire. In Lahore, there were 488
participants (mean age. 28 years-, male-to-female ratio, 1.4 to 1). In Guj
ranwala, there were 1,922 participants (mean age, 27 years: male-to-female
ratio, 1.5 to 1). The patients' blood was tested using an immuno-chromatogr
aphy to identify the antibody to hepatitis C using Instatest HCV, with very
high sensitivity, Results: In Lahore. the occurrence of anti-HCV-positive
serology was 15.9%, In Gujranwala, the occurrence of anti-HCV-positive sero
logy was 23.8%. In Lahore, the occurrence was 1.2% in participants 20 years
of age and younger and was 23.5% in those who were more than 20 years of a
ge. In Gujranwala, the occurrence of anti-HCV-positive serology was 5.4% in
participants 20 years of age and younger and was 34% in those who were mor
e than 20 years of age. Conclusion: It can be seen that in those younger th
an 20 years of age. the occurrence of hepatitis C is almost at par with the
rest of the world (0.5-2%). However, those more than 20 years of age had a
very high occurrence, as high as 50% in certain age groups. The time-frame
of contraction of the HCV for those individuals more than 20 years of age
(approximately 20 to 35 years ago) corresponds with that of the smallpox er
adication program conducted in Pakistan from 1964 to 1982. This may indicat
e the likelihood of a relationship between the high rate of hepatitis C and
the administration of the smallpox vaccine in Pakistan.
