Background. The aim of this investigation is to study the relationship between gastric morphology and serum biomarkers before and after Helicobacter pylori eradication. Methods. First-degree relatives of gastric cancer patients underwent gastroscopy before and 2.5 years after H. pylori eradication. The morphological changes in two categories (normal to mild and moderate to severe) were compared with level of pepsinogens I and II before eradication (n = 369), after eradication (n = 115), and in those with persistent infection (n = 250). Results: After eradication, pepsinogen I decreased to 70% and pepsinogen II to 45% of the previous values. Unlike pepsinogen II and pepsinogen I to II ratio that were affected by the severity of inflammation and atrophy in corpus in all groups, pepsinogen I generally did not change. After eradication, subjects with high mononuclear infiltration in corpus had lower pepsinogen I (54 versus 77.1 μ/mL), higher pepsinogen II (9.4 versus 6.9 μ/mL), and lower ratio (7.9 versus 11.6) than those without (P < 0.05). Conclusion. Pepsinogen II is a good marker of corpus morphological changes before and after H. pylori eradication.
Background: The combination of sofosbuvir and daclatasvir can be used to treat all genotypes of hepatitis C. Current guidelines for treating hepatitis C cirrhosis do not clarify weather 12 weeks or 24 weeks of treatment is appropriate. Objectives: In the present study, we aimed at evaluating the efficacy of sofosbuvir, daclatasvir, and ribavirin given for 12 weeks in treating cirrhotic patients with hepatitis C genotypes 1 and 3 infections. Methods: One hundred patients with hepatitis C and cirrhosis infected with Genotypes 1 and 3 were included in the present study. They were treated with 1 tablet of a combination pill of 400 mg sofosbuvir and 60 mg daclatasvir daily and weight-based ribavirin for 12 weeks. Response to treatment was assessed 12 weeks after the end of the treatment with a sensitive assay (SVR12). This study was registered with ClinicalTrials.gov, ID: NCT02596880. Results: One patient developed increased creatinine level following severe diarrhea and gastroenteritis and was excluded, 1 patient died due to unrelated reasons and 4 others were lost to follow-up. Among the 94 patients who finished the study, 92 achieved SVR12 (98%, per-protocol, 92% intention-to-treat). None of the patients reported any side effects. Of the 100 original patients, 56 were Genotype 1 and 44 were Genotype 3. One of the two patients not achieving SVR12 was Genotype 1, and the other two were Genotype 3.
Conclusions:The fixed-dose combination drug of sofosbuvir and daclatasvir given together with weight-base ribavirin for 12 weeks is extremely effective and safe in treating HCV patients with Genotypes 1 and 3 and cirrhosis.
The rs12979860 CC genotype was associated with SVR in patients receiving pegylated interferon plus ribavirin, however, the SVR rate in other rs12979860 genotypes was also relatively high.
HCV is a global health problem with an estimated 230 million chronically infected people worldwide. It has been reported that a 17-kd protein translated from core-encoding genomic region can contribute to immune-mediated mechanisms associated with the development of the chronic disease. Also, Treg cells can be contributed to an inadequate response against the viruses, leading to chronic infection. Here we evaluated the ability of protein F to modulate the frequency of CD4+CD25+FoxP3+T and IL-10+T cells in patients with chronic HCV infection. F gene was amplified and cloned in the expression vector. The protein was purified and used for stimulation of PBMCs in the HCV chronic patients and the control groups. The frequency of CD4+CD25+FoxP3+ T cell-like populations and IL-10-producing CD4+CD25+ T cells was assessed in the HCV-infected patients and in the healthy controls by flow cytometry, which showed an increase of both CD4+CD25+FoxP3+ T cell-like population and IL-10-producing CD4+CD25+ T cells in the HCV-infected patients positive for anti-F antibody. Our results suggest the potential involvement of F and core antigens in increasing the frequency of CD4+CD25+FoxP3+ T cell-like population and IL-10-producing CD4+CD25+ T cells which may be associated with HCV-persistent infection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
