Abstract
ObjectivesHBV and HDV are major public health problems with millions affected globally and Pakistan accounts for a significant proportion of the global Hepatitis burden. This cross sectional study was designed to assess the general epidemiological and virological features of HBV and HDV in the Punjab and Khyber Pakhtunkhawa (KP) provinces of Pakistan. MethodsA total of 1890 HBV patients from March 2016 to May 2017 were recruited in the study and the presence of HDV was retrospectively evaluated in all participants. Most participants were young adults (from 21 to 30 years). Genotyping was based on PCR amplification using primers specific for HBV genotypes A-F, and HDV. 405 nucleotide fragments of HDV were sequenced. MEGA was used for phylogenetic analysis. ResultsOverall prevalence of HBV was 14.08% (266/1890). Higher prevalence was observed in males (66.85%) as compared to females (33.15%). Co-infection of HDV was found in 39 (14.66%) patients. HBV genotype-D was prevalent in dual infections followed by HDV/A (p < 0.05).While HDV genotype 1 was predominant in all HBV positive samples. Compared to Punjab, coinfection was higher in KP (14.3% versus15.2%; p < 0.05). ConclusionThe prevalence of HBV and HDV is high in Pakistan. The description of HBV and HDV genotypes circulating in East and North-West Pakistan can contribute to a better understanding of their relevance in regional epidemics. These infections are highly endemic in the KP, where their control is confounded by its vast territorial dimension with small, hard-to-reach municipalities and diverse ethnic populations.
