<i>Helicobacter pylori</i> (<i>H. pylori</i>) is one of the most common pathogens that can cause certain gastrointestinal disorders, such as gastritis, peptic ulcers, and gastric cancer. Recently, interest in the systemic effects of <i>H. pylori</i> on extragastric manifestations is increasing. Representative diseases include hematologic, cardiovascular, neurodegenerative, autoimmune, dermatologic, allergic, hepatobiliary, and metabolic diseases. Among them, since the prevalence of metabolic diseases is on the rise worldwide, the relationship between <i>H. pylori</i> infection and metabolic diseases has become an interesting research issue. Many studies have been conducted to clarify any association. However, the results of those studies still remain controversial. This review focuses on recently published studies to investigate the relationship between <i>H. pylori</i> infection and metabolic diseases, including diabetes mellitus, metabolic syndrome, obesity, and non-alcoholic fatty liver disease, and their associated pathophysiology.

The aim: To analyze the relationship between non-alcoholic fatty liver disease and changes in the gut microbiota. Materials and methods: The publications of domestic and foreign editions in the databases of the United European Gastroenterology (UEG) Journal, PubMed, MEDLINE, Web of Science were processed and analyzed. Conclusions: In recent years, non-alcoholic fatty liver disease was placed among the important diseases in gastroenterology. During this time, more and more data appear on the link between changes in the human intestinal microbiome and the development of metabolic diseases, including NAFLD. Contemporary research has indeed found evidence of such a relationship. Thus, some strains of microorganisms have been identified in more detail, which directly or indirectly affect the development or course of the above-mentioned disease. For a better understanding of the strategies for the treatment of pathologies, it is necessary to delve into the study of etiological factors, therefore, NAFLC cannot be considered a pathology that has been sufficiently studied. Indeed, recent data indicate that the development and severity of the course of the disease are not always associated with the physiological processes already known to us.

Abstract Background Helicobacter pylori infection has been associated with insulin resistance and non-alcoholic fatty liver disease (NAFLD). This study was done to evaluate the effect of H. pylori-eradication therapy (HPET) in patients with NAFLD compared to standard management therapy (SMT). Methods Eighty NAFLD patients with H. pylori co-infection were randomized into SMT (diet and exercise, n = 36) and HPET (SMT plus amoxicillin, clarithromycin, and pantoprazole, n = 44) groups. The controlled attenuation parameter (CAP), anthropometric parameters, liver enzymes, lipid profile, and glycemic parameters including homeostasis model assessment-insulin resistance (HOMA-IR) were measured and compared between two groups at the baseline and 24 weeks. Results Sixty-four participants (SMT group [n = 28] and HPET group [n = 36]) were included in a modified intention-to-treat analysis. Both the SMT group and the HPET group had a significant reduction in CAP scores at 24 weeks (P = 0.002 and P &lt; 0.001, respectively), but the change between the groups was insignificant (P = 0.213). Successful eradication of H. pylori occurred in 68% of the HPET group and led to greater improvement in HOMA-IR at 24 weeks compared to SMT or non-responder patients (P = 0.007). The liver enzymes reduced significantly at 24 weeks in both groups, but the changes between the groups were similar. The lipid parameters remained unchanged within the groups and between the groups at 24 weeks. A significant increase in the levels of reduced glutathione was noted in the HPET group, but the change between the two groups was not statistically different. Conclusions HPET was found to be comparable to SMT alone in reducing hepatic steatosis and liver enzymes at 24 weeks in NAFLD patients. However, successful eradication of H. pylori led to greater improvement in HOMA-IR (Trial registration CTRI/2017/05/008608).

Abstract Background and objective The correlation between the eradication of Helicobacter pylori (HP) and non-alcoholic fatty liver disease (NAFLD) is a controversial one. The aim of this study is to investigate the effect of Helicobacter pylori treatment on liver function tests and lipid profiles and to compare its effects with exercise therapy and diet alone. Method This was a double-blind randomized clinical trial conducted at Qazvin University of Medical Sciences. One hundred patients with NAFLD having a positive test for urea breath testing were randomly assigned into one of the intervention and comparison groups. The diet and physical activity program were given to two groups of patients for 8 weeks, three sessions per week. In addition to the above therapy, the patients in the intervention group also received HP treatment for 2weeks. The data corresponding to anthropometric and clinical features before and after the intervention were collected in both groups and compared using appropriate statistical methods. Results After the treatment interventions, the variables of weight, BMI, blood glucose, triglyceride, AST, ALT, total cholesterol, and LDL-C were significantly decreased in both groups (p < .05). In the between-group comparisons, only ALT was significantly lower in the intervention group (HP) (p < .05). Conclusion Findings of this study showed that the eradication of Helicobacter pylori could significantly improve the ALT index, but it had no additional effect on changes in metabolic indicators.

Abstract Background Non-alcoholic fatty liver disease (NAFLD) is characterized by triglyceride accumulation in the hepatocytes in the absence of alcohol overconsumption, commonly associated with insulin resistance and obesity. Both NAFLD and type 2 diabetes (T2D) are characterized by an altered microbiota composition, however the role of the microbiota in NAFLD and T2D is not well understood. To assess the relationship between alteration in the microbiota and NAFLD while dissecting the role of T2D, we established a nested study on T2D and non-T2D individuals within the Cooperative Health Research In South Tyrol (CHRIS) study, called the CHRIS-NAFLD study. Here, we present the study protocol along with baseline and follow-up characteristics of study participants. Methods Among the first 4979 CHRIS study participants, 227 individuals with T2D were identified and recalled, along with 227 age- and sex-matched non-T2D individuals. Participants underwent ultrasound and transient elastography examination to evaluate the presence of hepatic steatosis and liver stiffness. Additionally, sampling of saliva and faeces, biochemical measurements and clinical interviews were carried out. Results We recruited 173 T2D and 183 non-T2D participants (78% overall response rate). Hepatic steatosis was more common in T2D (63.7%) than non-T2D (36.3%) participants. T2D participants also had higher levels of liver stiffness (median 4.8 kPa, interquartile range (IQR) 3.7, 5.9) than non-T2D participants (median 3.9 kPa, IQR 3.3, 5.1). The non-invasive scoring systems like the NAFLD fibrosis score (NFS) suggests an increased liver fibrosis in T2D (mean − 0.55, standard deviation, SD, 1.30) than non-T2D participants (mean − 1.30, SD, 1.17). Discussion Given the comprehensive biochemical and clinical characterization of study participants, once the bioinformatics classification of the microbiota will be completed, the CHRIS-NAFLD study will become a useful resource to further our understanding of the relationship between microbiota, T2D and NAFLD.
