Hepatitis B Virus Subgenotypes D1 And D3 Are Prevalent In Pakistan, Anwar Ali Siddiqui, Saeeda Baig, Runu Chakravarty Runu Chakravarty, Tariq Moatter

Anwar Ali Siddiqui

Background:

As the hepatitis B genotyping is important for assessing its clinical implications and geographical distribution, the sub-genotypes have been found useful for determination of specific genomic markers related to hepatocarcinogenesis. In Pakistan, there is no reported data on molecular evolutionary analysis of HBV. A study was, therefore, much needed to evaluate the spectra of mutations present in the strains prevalent here.

Findings:

To confirm specificity of PCR typing, phylogenetic analysis of the pre-S1 region and the divergence was studied through 13 sequences of 362 bp (accession number EF432765 – EF432777). A total of 315 serum samples, selected from HBsAg …

Serum pepsinogen, ui-antitrypsin (ui-AT) and blood groups were studied as genetic markets in 32 patients with endoscopically proven duodenal ulcer and 44 control subjects with no family history of ulcer disease. Serum pepsinogen was detennined by the modified method of Edward et al7, a1-AT by single radial hnmunodiffusion8 (RID) and phenotyping was carried out by isoelectric focusing (IEF)9. Duodenal ulcer patients with hyper- pepsinogenemia (28%) and low serum ui-AT (35%) had a dominant blood group 0, lower mean age, an early onset of disease, a higher frequency of gastrointestinal (CI) bleeding and ulcer perforation. These parameters were found considerably different …
