ABSTRACT
Objective:
To study the seroprevalence of hepatitis B virus (HBV) and hepatitis delta virus (HDV) infections in patients visiting outpatient department of a major tertiary care hospital in Khyber Pakhtunkhwa region of Pakistan.Methods:
Blood samples were collected from non-hospitalized patients. Serological analysis was done by ELISA and viral DNA was amplified by PCR. The amplified DNA was analyzed by agarose gel electrophoresis.Results:
Altogether, 946 blood samples were screened, overall percentage of HBsAg-positive patients remained 22.41%(prevalence224.10/1 000;CI0.197 5 ± 0.250 7) with the highest incidence rates among relatively younger age groups (20–29 years). The prevalence of HBV–HDV co-infection was found to be 46.75/1 000;CI0.031 8 ± 0.061 7. In HBsAg-positive patients, anti-HBc-total was detected in 86.79%while 25.00% were positive for anti-HBc-immunoglobulin M. Similarly, among these patients, HBV DNA was detected in 64.13% and 10.85% were co-infected with HDV. Different symptoms were associated with the prevailing infection, including malaise (62%), anorexia (66%) and fa-tigue (73%). The most commonly associated symptom was abdominal discomfort. Among these patients, certain risk factors, including surgery, visit to dentist and intravenus infusions were frequently associated with the infection (c2=95.23;df=11;P<0.000 1).Conclusions:
Overall, this study confirmed higher prevalence of active HBV/HDV infection, among young patients from Khyber Pakhtunkhwa region having no prior history of viral hepatitis.
