Assessment of the Prevalence of Hepatitis C and B Viruses in Patients with Hemophilia in Qom Province, (Iran)

Background and Objectives: Hemophilia is a hereditary bleeding disorder, which CFC (clotting factor concentration) method is used for prevention and treatment of about 70% of these patients. This method can play an important role in the transmission of blood-borne viruses, such as hepatitis B and C. According to studies, more than 40% of patients with hemophilia have one of the hepatitis C, B, and D, or HIV. The objective of this study was to determine prevalence of hepatitis B and C in the hemophilia population of Qom province.   Methods: This analytical cross-sectional study, was carried out on 90 patients with hemophilia Qom province, in 2017. Primary diagnosis and screening of hepatitis, were performed using serology for HBV and HCV; then, the samples were analyzed by PCR method. The data were statistically analyzed by Chi-square test.   Results: In this study, 70 subjects of the statistical population were male and 20 subjects were female, and their mean age was 27 years. In the serological survey, anti HCV, HBsAg, and HBcAb, were positive in 27.8%, 0%, and 11.1%, respectively. Moreover, the results of the PCR test for HBV was negative and for HCV was positive in 9 out of 25 individuals, who were anti-HCV positive.   Conclusion: The results of this study showed that among the blood-borne viral hepatitis in the hemophilia population, the incidence of hepatitis C is higher. Also, in recent years, monitoring the donated blood reduced the risk of the incidence of viral hepatitis in the blood recipient hemophilic populations. Accordingly, continuous testing and paying attention to the vaccination schedule seems to be necessary in this group of patients

Gut Hormone Pharmacology of a Novel GPR119 Agonist (GSK1292263), Metformin, and Sitagliptin in Type 2 Diabetes Mellitus: Results from Two Randomized Studies

<div><p></p><p>GPR119 receptor agonists improve glucose metabolism and alter gut hormone profiles in animal models and healthy subjects. We therefore investigated the pharmacology of GSK1292263 (GSK263), a selective GPR119 agonist, in two randomized, placebo-controlled studies that enrolled subjects with type 2 diabetes. Study 1 had drug-naive subjects or subjects who had stopped their diabetic medications, and Study 2 had subjects taking metformin. GSK263 was administered as single (25–800 mg; n = 45) or multiple doses (100–600 mg/day for 14 days; n = 96). Placebo and sitagliptin 100 mg/day were administered as comparators. In Study 1, sitagliptin was co-administered with GSK263 or placebo on Day 14 of dosing. Oral glucose and meal challenges were used to assess the effects on plasma glucose, insulin, C-peptide, glucagon, peptide tyrosine-tyrosine (PYY), glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP). After 13 days of dosing, GSK263 significantly increased plasma total PYY levels by ∼five-fold compared with placebo, reaching peak concentrations of ∼50 pM after each of the three standardized meals with the 300 mg BID dose. Co-dosing of GSK263 and metformin augmented peak concentrations to ∼100 pM at lunchtime. GSK263 had no effect on active or total GLP-1 or GIP, but co-dosing with metformin increased post-prandial total GLP-1, with little effect on active GLP-1. Sitagliptin increased active GLP-1, but caused a profound suppression of total PYY, GLP-1, and GIP when dosed alone or with GSK263. This suppression of peptides was reduced when sitagliptin was co-dosed with metformin. GSK263 had no significant effect on circulating glucose, insulin, C-peptide or glucagon levels. We conclude that GSK263 did not improve glucose control in type 2 diabetics, but it had profound effects on circulating PYY. The gut hormone effects of this GPR119 agonist were modulated when co-dosed with metformin and sitagliptin. Metformin may modulate negative feedback loops controlling the secretion of enteroendocrine peptides.</p><p>Trial Registration:</p><p>Clinicaltrials.gov <a href="http://www.clinicaltrials.gov/ct2/show/NCT01119846" target="_blank">NCT01119846</a> Clinicaltrials.gov <a href="http://www.clinicaltrials.gov/ct2/show/NCT01128621" target="_blank">NCT01128621</a></p></div
