Objective: The aim of this study was to compare the efficacy and safety of 2-week levofloxacin-containing triple therapy, levofloxacin-containing bismuth quadruple therapy, and standard bismuth-containing quadruple therapy as a first-line regimen for the eradication of Helicobacter pylori.Methods: A total of 329 patients with H. pylori infection were randomly divided into 3 groups to receive one of the following regimens: (a) levofloxacin-containing bismuth quadruple therapy, RBAL (rabeprazole 20 mg, b.i.d., bismuth subsalicylate 562 mg, b.i.d., amoxicillin 1 g, b.i.d, levofloxacin 500 mg, once daily), (b) standard bismuth quadruple therapy, RBMT (rabeprazole 20 mg, b.i.d, subsalicylate 562 mg, b.i.d., metronidazole 500 mg, t.i.d, tetracycline 500 mg, q.i.d), or (c) levofloxacin-containing triple therapy, RAL (rabeprazole 20 mg, b.i.d., amoxicillin 1 g, b.i.d, levofloxacin 500 mg, once daily). The primary outcome was the eradication rate in the intention-to-treat (ITT) and per protocol (PP) analysis. Results: The eradication rates of the above 3 groups using ITT analysis were RBAL 83.8%, RBMT 88.3%, and RAL 74.8% compared with 91.2, 92.5, and 79.2%, respectively, using PP analysis. The eradication rate using RBMT was significantly higher than that of RAL (p = 0.029 in ITT analysis and p = 0.017 in PP analysis). Several side effects occurred in 156 patients (54.1%) in the RBAL group, 215 (52.3%) in the RBMT group, and 56 (26.2%) in the RAL group (p > 0.05, RBAL vs. RBMT; p < 0.001, RBMT vs. RAL; p < 0.001, RBAL vs. RAL). Conclusion: All bismuth-containing quadruple therapies had acceptable eradication rates, but levofloxacin-containing triple therapy was not as good as quadruple therapies. Hence, quadruple therapies should be considered the preferred first-line therapy for H. pylori infections.

Introduction Gastric cancer is ranked fourth among all cancers in the world and second in cancer-related deaths. Gastritis leads to the activation of neutrophils, lymphocytes, macrophages, and platelets. Long-term inflammation leads to multistage histopathologic changes called Correa tract,...

Background: Non-alcoholic fatty liver disease (NAFLD) has a high prevalence among patients undergoing laparoscopic sleeve gastrectomy (LSG). Although liver biopsy is the gold standard for assessing histopathologic changes in the liver, it is an invasive procedure. The objective of this study was to evaluate the effect of sleeve gastrectomy on liver enzymes, fibrosis and steatosis scores; ultrasonographic findings; biochemical parameters; and anthropometric measurements in morbidly obese patients with NAFLD. Methods: Ninety-seven obese patients who underwent LSG were included in this study. Sex, age, body mass index (BMI), comorbidities, liver enzymes, ultrasonographic findings and laboratory parameters to calculate fibrosis and steatosis scores were collected before surgery and after 1 year of follow-up. Results: A total of 88.7% of patients had liver steatosis at the pre-surgical ultrasonographic evaluation and this ratio decreased to 46.4% 1 year after surgery. Alanine aminotransferase (ALT), homeostatic model assessment of insulin resistance index (HOMA-IR), aspartate aminotransferase-to-platelet ratio index (APRI) and liver fat score (LFS) were significantly higher in patients with steatosis grade III vs. others. There were improvements in high-density lipoprotein (HDL), triglycerides (TG), glycated hemoglobin (HbA_1c), glucose, insulin, BMI, liver enzymes and all NAFLD-related fibrosis and steatosis scores. Conclusions: HOMA-IR, ALT, LFS and APRI scores can be used for follow-up procedures in morbidly obese patients with NAFLD who underwent LSG.

Nonalcoholic fatty liver disease (NAFLD) is considered one of the most important causes of chronic liver disorders in the world. Dietary pattern is a modifiable risk factor that represents the main target for the prevention and treatment of NAFLD. The aim of this cross-sectional study was to assess the impact of low-fat diet on anthropometric measurements, biochemical, and inflammatory parameters in individuals with obesity/overweight and NAFLD. A total of 108 individuals (n = 59 males and n = 49 females) aged between 19 and 65 years participated in the 12-week weight loss program. Dietary treatment plans including low-fat diets were randomly prescribed for each individual. Anthropometric measurements were collected by a trained dietitian at baseline and 12-week follow-up. Blood samples were collected for each individual at baseline and 3rd month for biochemical measurements and enzyme-linked immunosorbent assay analysis for tumor necrosis factor-α (TNF-α), interleukin (IL)-6, fibroblast growth factor-21 (FGF-21), chemerin, and irisin levels in plasma. At the end of the study, body weight, body mass index, body fat % body fat mass (kg) reduced significantly in females and males (P < .05). Moreover, reductions in waist, hip, and neck circumferences were significant in both groups. Changes in alanine aminotransferase and aspartate aminotransferase levels were significant in 3rd month. After 3 months, reductions in TNF-α, IL-6, and FGF-21 levels were significant in individuals with obesity/overweight and NAFLD. While no significant change in chemerin and irisin levels was found. These results show that low-fat diet over a 12-week period led to improvements in both anthropometric measurements and biochemical parameters in individuals with obesity/overweight and NAFLD.
