Hemophilia is a rare bleeding disorder that needs plasma or clotting factor
concentrate transfusion. Therefore chances of blood-borne pathogens like HCV transmission
increase due to high prevalence in healthy donors. This study was aimed to determine the
prevalence of HCV genotypes and associated risk factors in hemophilia patients of Khyber
Pakhtunkhwa, Pakistan. Blood samples and data were collected from 672 hemophiliacs after
proper consent obtained from each patient. Samples were analyzed for anti-HCV, HCV RNA
and HCV genotype/s detection. Of the total, 22.32% (150) were anti-HCV positive, of which
HCV RNA was detected in 18.45% (124) individuals. HCV genotype 3a was found with
significantly higher prevalence (p<0.05) (19.35%) as compared to 2a (16.13%) and 1a (12.90%).
HCV-3b and HCV-4 were found each in 3.22% samples. Dual infection of genotypes was found
in 22.58% of individuals and 22.58% HCV RNA positive sampels were not typed. A total of 572
(85.12%) subjects had hemophilia A and 100 (14.88%) had hemophilia B. In hemophiliacs A the
most dominant genotype was 3a (19.27%) while in hemophilia B, genotype 1a was prevalent
(26.67%). Whole blood and plasma transfusion were observed as the main risk factors of HCV.
It is concluded that HCV genotype 3a and 2a are prevalent in hemophilia patients of Khyber
Pakhtunkhwa Pakistan and the main risk factor observed was an unscreened whole blood
transfusion.

OBJECTIVETo study the effect of oral administration of dimethyl dimethoxy biphenyl dicarboxylate (DDB) on adjusting angiogeneic/inflammatory mediators and ameliorating the pathology of bones in rats with collagen-induced arthritis (CIA).
METHODSWistar rat model of CIA was set up using bovine collagen type II. Fifty rats were divided into five groups randomly: normal, CIA model, DDB treatment, methotrexate (MTX) treatment, and combined DDB+MTX treatment. Ankle joints of rats were imaged with digital X-ray machine to show the destruction of joints. Fore and hind paw and knee joints were removed above the ankle joint then processed for haematoxylin and eosin staining. Plasma levels of vascular endothelial growth factor (VEGF), platelet derived growth factor, interleukin-8 (IL-8), IL-4, tumor necrosis factor α (TNF-α), and cyclooxygenase-2 (COX-2) were quantified by enzyme-linked immunosorbent assay. Nitric oxide levels were detected by Griess reagent.
RESULTSCompared with the CIA model group, a remarkable reduction in various angiogenic (VEGF and IL-8) and inflammatory mediators (TNF-α, IL-4 and COX-2) after treatment with DDB either alone or combined with MTX P<0.05 or P<0.01). Histopathological and X-ray findings were confirmatory to the observed DDB anti-arthritic effect. The DDB-treated group showed amelioration in signs of arthritis which appeared essentially similar to normal.
CONCLUSIONOur data shed light on the therapeutic efficacy of DDB in experimental rheumatoid arthritis (RA) compared with a choice drug (MTX) and it may be offered as a second-line drug in the treatment of RA.
