Abstract
Gastric cancer (GC) is still one of the most prevalent cancers worldwide, with a high mortality rate, despite improvements in diagnostic and therapeutic strategies. To diminish the GC burden, a modification of the current diagnostic paradigm, and especially endoscopic diagnosis of symptomatic individuals, is necessary. In this review article, we present a broad review and the current knowledge status on serum biomarkers, including pepsinogens, gastrin, Gastropanel®, autoantibodies, and novel biomarkers, allowing us to estimate the risk of gastric precancerous conditions (GPC)-atrophic gastritis and gastric intestinal metaplasia. The aim of the article is to emphasize the role of non-invasive testing in GC prevention. This comprehensive review describes the pathophysiological background of investigated biomarkers, their status and performance based on available data, as well as their clinical applicability. We point out future perspectives of non-invasive testing and possible new biomarkers opportunities.

Abstract
Helicobacter pylori (H. pylori) infection is thought to impact various extragastric diseases, including nonalcoholic fatty liver disease (NAFLD), the most common chronic liver disease. Meanwhile, the pathogenesis of NAFLD needs further research, and effective treatment for this disease remains elusive. In this mini-review, we enumerate and ponder on the evidence demonstrating an association between H. pylori infection and NAFLD. Primarily, we delve into high-quality meta-analyses and clinical randomized controlled trials focusing on the association studies between the two. We also discuss clinical studies that present opposite conclusions. In addition, we propose a mechanism through which H. pylori infection aggravates NAFLD: inflammatory cytokines and adipocytokines, insulin resistance, lipid metabolism, intestinal barrier and microbiota, H. pylori outer membrane vesicles and H. pylori-infected cell-extracellular vesicles. This mini-review aims to further explore NAFLD pathogenesis and extragastric disease mechanisms caused by H. pylori infection.

Relationship of Helicobacter pylori Infection with Nonalcoholic Fatty Liver Disease: A Meta-Analysis. Can J Gastroenterol Hepatol 2023; 2023:5521239. [PMID: 36742347 PMCID: PMC9891807 DOI: 10.1155/2023/5521239] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 12/17/2022] [Accepted: 12/24/2022] [Indexed: 01/27/2023] Open
Abstract
Background and Aims Helicobacter pylori (H. pylori) and nonalcoholic fatty liver disease (NAFLD) have become increasingly recognized, both of which affect human health globally. The association of H. pylori infection with NAFLD remains unclear. Methods PubMed, EMBASE, and Cochrane Library databases were searched. Only a random-effects model was used. Odds ratios (ORs) and risk ratios (RRs) with 95% confidence intervals (CIs) were calculated for the combined estimates of raw data. Adjusted ORs (aORs) and hazard ratios (aHRs) with 95% CIs were calculated for the combined estimates of data adjusted for confounders. Results Thirty-four studies with 218573 participants were included. Based on unadjusted data from 26 cross-sectional studies and 3 case-control studies, H. pylori infection was significantly associated with the presence of NAFLD (OR = 1.26, 95% CI = 1.17-1.36, P < 0.001). Based on adjusted data from 15 cross-sectional studies and 1 case-control study, H. pylori infection was significantly associated with the presence of NAFLD (aOR = 1.25, 95% CI = 1.08-1.44, P < 0.001). Compared with control subjects without NAFLD, patients with moderate (OR = 1.67, 95% CI = 1.17-2.39, P = 0.005) and severe (OR = 1.71, 95% CI = 1.30-2.24, P < 0.001) NAFLD, but not those with mild NAFLD (OR = 1.14, 95% CI = 0.9-1.45, P = 0.286), had significantly higher proportions of H. pylori infection. The association of H. pylori infection with the occurrence of NAFLD was statistically significant based on adjusted data from 3 cohort studies (aHR = 1.18, 95% CI = 1.05-1.34, P = 0.007), but not based on unadjusted data from 3 cohort studies (RR = 1.41, 95% CI = 0.80-2.48, P = 0.237). Conclusion H. pylori infection is associated with NAFLD, especially moderate and severe NAFLD. The impact of H. pylori eradication on the prevention of NAFLD should be further explored.

Abstract
BACKGROUND The association between Helicobacter pylori (Hp) infection and non-alcoholic fatty liver disease (NAFLD) is subject of a contentious debate. Data mainly stem from Asian cohorts whereas European data are scarce. We, therefore, investigated an Austrian colorectal cancer screening cohort for an association between Hp and NAFLD. METHODS In total, 5338 consecutive participants undergoing screening colonoscopy at a single center in Austria were evaluated in this cross-sectional study. The primary risk factor was being Hp negative or positive. The primary endpoint was the presence of NAFLD defined by ultrasound (NAFLD; primary endpoint). Uni- and multivariable logistic regression models were fitted to obtain odds ratios (OR) and 95% confidence intervals (95%CI). Finally, this association was analyzed in a subgroup of 1128 patients in whom NAFLD was diagnosed by transient elastography (TE, secondary endpoint). RESULTS NAFLD prevalence defined by ultrasound did not differ between Hp positive (48%) and negative patients (45%, P=0.097). Accordingly, in uni- (OR 1.12 95% CI 0.98-1.29; P=0.098) and multivariable analysis adjusting for different risk factors (aOR 0.96 95%CI 0.82-1.13; P=0.601) no independent association was found. On subgroup analysis, NAFLD diagnosed by TE was more prevalent in the Hp positive compared to the Hp negative group (49% vs. 38%, P=0.004) and these patients also had higher steatosis grades. However, after adjustment for risk factors, no independent association between Hp positivity and NAFLD diagnosed by TE (aOR 1.26 95%CI 0.89-1.78; P=0.194) was confirmed. CONCLUSIONS In this Central European cohort, Hp-positivity was not associated with the diagnosis of NAFLD. Although Hp positive patients seem to be more likely to have a concomitant NAFLD diagnosis, this association might rather relate to a cardiometabolic risk phenotype than causality.

Abstract
Abstract
Background: Recently, with new diagnosis criteria, metabolic associated fatty liver disease (MAFLD) was introduced to replace the diagnosis of nonalcoholic fatty liver disease (NAFLD). Considering that there weren’t sufficient studies on MAFLD in China, we aimed to explore the relationship between MAFLD and H. pylori infection, as well as the potential risk factors of MAFLD.Methods: In this cross-sectional study, 3449 subjects were enrolled from a Hospital Health Management Center of Shantou in China between July 2020 and October 2021. All participants included had underwent blood test, 13C urea breath test (13C-UBT) and abdominal ultrasound examination. The association between H. pylori infection and MAFLD were analyzed using logistic regression. Machine learning approach were applied to explore independent risk factors of MAFLD.Results: The overall prevalence of MAFLD was 39.4% in our study population. Of a total of 3449 participants, MAFLD was diagnosed in 1043 of 2254 males (46.3%) and 315 of 1195 females (26.4%). The prevalence of MAFLD increased with age and peaked at the 60-69-year age group (overall participants: 58.8%; male: 56.2%; female: 64.0%), and then declined slightly in the 70-above-year age group. The result of multivariable logistic regression revealed that H. pylori infection was not significantly correlated with MAFLD. Using logistic regression and LASSO regression, we identified age, overweight/obesity, T2DM, hypertension, UA, TG, HDL and ALT as independent risk factors of MAFLD.Conclusions: The prevalence of MAFLD in Shantou of south China was relatively high, and the prevalence was higher in males than in females. Our results showed that H. pylori infection wasn’t associated with the risk of MAFLD, when age, overweight/obesity, T2DM, hypertension, UA, TG, HDL and ALT were independent risk factors of MAFLD.

Abstract
Metabolic-associated fatty liver disease (MAFLD) is a chronic liver disease that affects about a quarter of the world population. MAFLD encompasses different disease stadia ranging from isolated liver steatosis to non-alcoholic steatohepatitis (NASH), fibrosis, cirrhosis and hepatocellular carcinoma. Although MAFLD is considered as the hepatic manifestation of the metabolic syndrome, multiple concomitant disease-potentiating factors can accelerate disease progression. Among these risk factors are diet, lifestyle, genetic traits, intake of steatogenic drugs, male gender and particular infections. Although infections often outweigh the development of fatty liver disease, pre-existing MAFLD could be triggered to progress towards more severe disease stadia. These combined disease cases might be underreported because of the high prevalence of both MAFLD and infectious diseases that can promote or exacerbate fatty liver disease development. In this review, we portray the molecular and cellular mechanisms by which the most relevant viral, bacterial and parasitic infections influence the progression of fatty liver disease and steatohepatitis. We focus in particular on how infectious diseases, including coronavirus disease-19, hepatitis C, acquired immunodeficiency syndrome, peptic ulcer and periodontitis, exacerbate MAFLD. We specifically underscore the synergistic effects of these infections with other MAFLD-promoting factors.

Abstract
Introduction:Helicobacter pylori (H. pylori) infection is positively associated with cardiovascular diseases, but the involvement of lipids in this association remains unclear. The present study reviewed the changes in circulating lipid levels following H. pylori eradication. Methods: A PubMed database was searched until December 2020 to identify randomized control trials (RCTs) and non-RCTs investigating the effect of H. pylori eradication on the lipid levels in inverse variance-weighted, random-effects meta-analyses. Results: A total of 24 studies (four RCTs and 20 non-RCTs) with 5270 participants were identified. The post-eradication levels were increased for high-density lipoprotein cholesterol (HDL-C; mean difference (MD) 2.28 mg/dL, 95% confidence interval (CI) 1.90 to 2.66) and triglyceride (TG; MD 3.22 mg/dL, 95% CI 1.13 to 5.31) compared with the pre-eradication levels. H. pylori eradication resulted in little to no difference in the low-density lipoprotein-cholesterol levels (MD −2.33 mg/dL, 95% CI −4.92 to 0.26). In the analyses of RCTs only, the findings for elevated HDL-C levels, but not TG, were robust. Conclusions:H. pylori eradication increases the HDL-C levels. Further studies are needed to elucidate the effects of lipid changes following H. pylori eradication on cardiovascular diseases.

Abstract
Helicobacter pylori is one of the most prevalent infection worldwide. It affects individuals of different age groups. Elderly people tend to resist eradication treatment and worsening of infection can lead to several gastric and non-gastric pathologies. Aging-associated cellular and molecular alteration can increase the risk of other pathologies such as osteoporosis, Alzheimer's disease, Parkinson's disease, respiratory and renal dysfunction, and cancer in geriatric patients, more than other age groups. This review article highlights some of the most common old age diseases and the role of H. pylori infection as a risk factor to worsen the conditions, presented by the molecular evidences of these associations. These studies can help clinicians to understand the underlying pathogenesis of the disease and identify high-risk patients, aiding clearer diagnosis and treatment.

Abstract
BACKGROUND Recent studies that have examined the association between Helicobacter pylori infection and risk of nonalcoholic fatty liver disease (NAFLD) have produced conflicting data. We have performed a systematic review and meta-analysis to assess the association between H. pylori infection and risk of NAFLD. METHODS We searched PubMed, Web of Science and Scopus databases using predefined keywords to identify observational studies (published up to November 2018), in which NAFLD was diagnosed by histology, imaging or biochemistry. Data from selected studies were extracted and meta-analysis was performed using random-effects modeling. The statistical heterogeneity among studies (I2-index), subgroup analyses and the possibility of publication bias were assessed. RESULTS Thirteen observational (11 cross-sectional/case-control and 2 longitudinal) studies involving a total of 81,162 middle-aged individuals of predominantly Asian ethnicity (47.5% of whom had H. pylori infection diagnosed by urea breath test, faecal or serological tests) were included in the final analysis. Meta-analysis of data from cross-sectional and case-control studies showed that H. pylori infection was associated with increased risk of prevalent NAFLD (n = 11 studies; random-effects odds ratio [OR] 1.20, 95% CI 1.07-1.35; I2 = 59.6%); this risk remained significant in those studies where analysis was fully adjusted for age, sex, smoking, adiposity measures, diabetes or dyslipidemia (random-effects OR 1.19, 95% CI 1.07-1.32, I2 = 0%). Meta-analysis of data from longitudinal studies showed that H. pylori infection was also associated with increased NAFLD incidence (n = 2 studies; random-effects hazard ratio 1.14, 95% CI 1.05-1.23; I2 = 0%). Sensitivity analyses did not alter these findings. Funnel plot did not reveal significant publication bias. CONCLUSIONS H. pylori infection is associated with mildly increased risk of both prevalent and incident NAFLD in middle-aged individuals. More prospective studies, particularly in non-Asian populations, and mechanistic studies are required to better elucidate the link between chronic H. pylori infection and NAFLD.

Helicobacter 2019; 24:e12576. [PMID: 30907050 DOI: 10.1111/hel.12576] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2018] [Revised: 02/01/2019] [Accepted: 02/07/2019] [Indexed: 12/20/2022]
Abstract
BACKGROUND The association between Helicobacter pylori (H. pylori) infection and nonalcoholic fatty liver disease (NAFLD) has been shown in many observational studies, but these conclusions remain controversial. Hence, we performed a meta-analysis to elucidate the association. METHODS A comprehensive search was conducted on relevant studies published from inception to December 31, 2018, in PubMed, EMBASE, and Web of Science databases. Odds ratio (OR) with 95% confidence interval (95% CI) were pooled by random-effect model, generic inverse variance method. Subgroup and sensitivity analyses were also done. Publication bias was estimated by the funnel plot, Begg's test, and Egger's test. RESULTS Fifteen studies (eleven cross-sectional, two case-control, and two cohort studies) were included in this meta-analysis. The pooled OR of NAFLD in patients with H. pylori infection was 1.19 (95% CI: 1.11-1.29, P < 0.00001) when compared with the patients without H. pylori infection. Similar results were observed when the subgroup analyses were stratified by different geographical locations, study designs, and confounders adjustment. In subgroup analysis stratified by different H. pylori testing methods, the correlation still exists when using UBT, serology, RUT, or SAT, but there was no statistically significant difference when using multiple detection methods (OR = 2.96, 95% CI: 0.37-23.94, P = 0.31). Sensitivity analyses showed that our results were robust. No evidence of substantial publication bias was detected. CONCLUSIONS Current evidence indicated that a positive association between H. pylori infection and the risk of NAFLD. Further prospective studies are warranted to strengthen the association and to clarify whether there is a causative link between them.

Abstract
The association between Helicobacter pylori (H. pylori) infection and metabolic syndrome (MetS) determined in different cohorts from different countries is currently inconclusive. In the majority of previous studies, H. pylori infection was diagnosed based on the presence of H. pylori IgG antibody in the serum. However, to the best of our knowledge, only few studies have investigated the association between H. pylori infection and MetS using the urea breath test (UBT) as a diagnostic tool. The present study was performed with the aim of providing a detailed analysis of the association between H. pylori infection, as diagnosed by the UBT method, and MetS in a large community from Zhejiang province in eastern China. The results indicated that H. pylori infection increases the risk of MetS in the aged female population.

Abstract
Both Helicobacter pylori (H. pylori) infection and liver diseases, including nonalcoholic fatty liver disease (NAFLD), viral hepatitis, and hepatocellular carcinoma (HCC), have high prevalences worldwide, and the relationship between H. pylori infection and liver disease has been discussed for many years. Although positive correlations between H. pylori and NAFLD have been identified in some clinical and experimental studies, negative correlations have also been obtained in high-quality clinical studies. Associations between H. pylori and the pathogenesis of chronic viral hepatitis, mainly disease progression with fibrosis, have also been suggested in some clinical studies. Concerning HCC, a possible role for H. pylori in hepatocarcinogenesis has been identified since H. pylori genes have frequently been detected in resected HCC specimens. However, no study has revealed the direct involvement of H. pylori in promoting the development of HCC. Although findings regarding the correlations between H. pylori and liver disease pathogenesis have been accumulating, the existing data do not completely lead to an unequivocal conclusion. Further high-quality clinical and experimental analyses are necessary to evaluate the efficacy of H. pylori eradication in ameliorating the histopathological changes observed in each liver disease.

Abstract
We investigated the relationship of H. pylori stratified by cytotoxin-associated gene A (cagA) status with nonalcoholic fatty liver disease (NAFLD) in the general population of the United States (US). We utilized the Third National Health and Nutrition Examination Survey from 1988 to 1994 in this study. NAFLD was defined by ultrasonographic detection of hepatic steatosis in the absence of other known causes of liver diseases and significant alcohol consumption. Hepatic steatosis was assessed by parenchymal brightness, liver to kidney contrast, deep beam attenuation, bright vessel walls and gallbladder wall definition. Antibodies to H. pylori and cagA of participants were measured using H. pylori IgG and anti-cagA IgG enzyme-linked immunosorbent assays. Among 5,404 participants, the prevalence of NAFLD was higher in H. pylori positive subjects (33.5±1.8%) compared to H. pylori negative subjects (26.1±1.7%, p <0.001). In terms of cagA protein status stratification, while cagA positive H. pylori group did not demonstrate an association with NAFLD (OR: 1.05; 95% CI: 0.81-1.37), cagA negative H. pylori group was noted to have a significant association with NAFLD in a multivariable analysis (OR: 1.30; 95% CI: 1.01-1.67). In conclusion, our study demonstrated that cagA negative H. pylori infection was an independent predictor of NAFLD in the US general population.

Abstract
To evaluate how metformin plus rosiglitazone affect serum adiponectin levels in people suffering from type 2 diabetes mellitus (T2DM), 240 patients having T2DM were selected in this cohort study. Included subjects were randomly and equally separated into three subsets: i) Group A (rosiglitazone group); ii) group B (metformin group); and iii) group C (rosiglitazone + metformin group). Furthermore, meta-analysis of previous studies was performed by searching the general search engines and bibliographic databases. Compared with before treatment, the serum amount of adiponectin grew considerably in the three groups after treatment, and the levels in the group C was much greater than those of groups A and B (all P<0.05). Corresponding meta-analysis results suggested post-treatment serum adiponectin level to be greater than pretreatment level in T2DM patients (P<0.001). Further subgroup analyses indicated that combination therapy of metformin and rosiglitazone may increase the amount of serum adiponectin in T2DM sufferers among the majority subgroups (all P<0.05). The combination of metformin and rosiglitazone treatment increased serum adiponectin levels, suggesting that metformin plus rosiglitazone therapy is a suitable choice to treat T2DM.

Abstract
Helicobacter pylori (H. pylori), discovered in 1982, is a microaerophilic, spiral-shaped gram-negative bacterium that is able to colonize the human stomach. Nearly half of the world's population is infected by this pathogen. Its ability to induce gastritis, peptic ulcers, gastric cancer and mucosa-associated lymphoid tissue lymphoma has been confirmed. The susceptibility of an individual to these clinical outcomes is multifactorial and depends on H. pylori virulence, environmental factors, the genetic susceptibility of the host and the reactivity of the host immune system. Despite the host immune response, H. pylori infection can be difficult to eradicate. H. pylori is categorized as a group I carcinogen since this bacterium is responsible for the highest rate of cancer-related deaths worldwide. Early detection of cancer can be lifesaving. The 5-year survival rate for gastric cancer patients diagnosed in the early stages is nearly 90%. Gastric cancer is asymptomatic in the early stages but always progresses over time and begins to cause symptoms when untreated. In 97% of stomach cancer cases, cancer cells metastasize to other organs. H. pylori infection is responsible for nearly 60% of the intestinal-type gastric cancer cases but also influences the development of diffuse gastric cancer. The host genetic susceptibility depends on polymorphisms of genes involved in H. pylori-related inflammation and the cytokine response of gastric epithelial and immune cells. H. pylori strains differ in their ability to induce a deleterious inflammatory response. H. pylori-driven cytokines accelerate the inflammatory response and promote malignancy. Chronic H. pylori infection induces genetic instability in gastric epithelial cells and affects the DNA damage repair systems. Therefore, H. pylori infection should always be considered a pro-cancerous factor.

Abstract
PURPOSE OF REVIEW Helicobacter pylori (HP) infection is known to be a significant risk factor in the development of certain gastric conditions, such as ulcers, gastritis, and malignancy. Recently, however, the systemic effect of HP infection on other organ systems has come to be appreciated. In this review, we will explore the association between HP infection and nonalcoholic fatty liver disease (NAFLD), the hepatic component of metabolic syndrome. RECENT FINDINGS The possible association between HP infection and NAFLD initially stemmed from the isolation of HP bacteria in the livers of patients with NAFLD. Although there have been conflicting results, several subsequent clinical trials have demonstrated a higher rate of fatty liver and NASH in HP-positive patients compared to HP-negative patients; in addition, small trials examining the effect of HP eradication have shown improvement in markers of NAFLD activity, further supporting a link between these two conditions. The pathophysiology behind the possible association between HP infection and NAFLD has yet to be fully elucidated; several possible mechanisms include induction of a pro-inflammatory state that shifts the body toward a more lipogenic profile, and a hormonal shift that favors progression toward insulin resistance and fibrosis. The association between HP infection and NAFLD has been demonstrated in several clinical trials, including small trials evaluating the effect of HP eradication on NAFLD. Future studies examining the pathophysiology behind this association are the next step in characterizing the relationship between these two conditions.

Abstract
INTRODUCTION Previous studies have shown a close relationship between Helicobacter pylori (H. pylori), insulin resistance, and altered metabolic parameters. However, the effects of H. pylori eradication on these conditions remain controversial. We carried out a systematic review and meta-analysis to evaluate the effects of H. pylori eradication on insulin resistance and metabolic parameters. METHODS We searched CENTRAL, MEDLINE, and EMBASE databases from their inception to July 2016. Insulin resistance (HOMA-IR), body weight (BW), BMI, waist circumference, triglycerides (TG), high-density and low-density lipoprotein-cholesterol (HDL-C and LDL-C), and fasting blood glucose (FBG) were compared between patients with and without H. pylori eradication using a random-effects model. We reported pooled mean differences (MD) and 95% confidence intervals (CI) for the change in outcomes. RESULTS Data from five studies showed no difference in HOMA-IR after H. pylori eradication (pooled MD=-0.52, 95% CI: -1.47 to 0.42). Eradication significantly increased BMI (MD=0.36, 95% CI: 0.11-0.60) and BW (MD=1.1, 95% CI: 0.8-1.5), but had no significant effects on TG, LDL-C, HDL-C, or FBG. CONCLUSION H. pylori eradication does not improve insulin resistance, TG, HDL-C, LDL-C, or FBG, but may increase BW and BMI. Further studies are needed to clarify the effect of H. pylori eradication on metabolism.

Abstract
OBJECTIVE To systematically review and quantify the effect of Helicobacter pylori (H. pylori) infection on the risk of metabolic syndrome (MS) and metabolic parameters in individuals with H. pylori infection. METHODS A systematic search of MEDLINE and EMBASE was performed. Inclusion criteria were observational studies assessing the association between H. pylori infection and MS in adult participants. We calculated the pooled effect estimate of MS with 95% confidence interval (CI) between patients infected with H. pylori and those without by using a random-effects model. The secondary outcomes were the differences between groups in homeostatic model assessment of insulin resistance (HOMA-IR), triglyceride, high-density lipoprotein cholesterol (HDL-C), fasting blood glucose (FBG), body mass index (BMI) and systolic blood pressure (SBP). RESULTS Altogether 18 trials with 27 544 participants met the inclusion criteria. Six trials were included in the analysis of MS. There was a statistically significant association between H. pylori and MS with a pooled odds ratio of 1.34 (95% CI 1.17-1.53, I(2) = 39%, Pheterogeneity < 0.01). Between the infected and non-infected groups there were significant differences in FBG, HDL-C, BMI, triglyceride, HOMA-IR and SBP (all P < 0.05). CONCLUSION H. pylori infection is positively associated with MS. Infection with H. pylori is also associated with higher triglyceride, FBG, BMI, HOMA-IR, SBP and lower HDL-C.

Abstract
OBJECTIVE In this study, we examined the association between two adiponectin (ADPN) gene polymorphisms, +45T/G and +276G/T, and susceptibility to diabetic peripheral neuropathy (DPN) in type 2 diabetes mellitus (T2DM) patients. METHODS A total of 180 T2DM patients were enrolled in this study and assigned to two groups: DPN group (n=90) and non-DPN (NDPN) group (n=90). In addition, 90 healthy subjects were chosen as healthy normal control (NC). The plasma level of ADPN was quantified by ELISA method and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used for genotype analysis of the two ADPN polymorphisms, +45T/G (rs2241766) and +276G/T (rs1501299), in all the study subjects. Statistical analysis of data was performed with SPSS version 20.0 software. RESULTS Serum levels of ADPN were markedly reduced in the DPN group compared to NDPN and NC groups (all P<0.05). The frequencies of TT, TG and GG genotypes and the T and G alleles of T45G and G276T polymorphisms in DPN group were significantly different than the NDPN group (all P<0.05). Notably, T45G and G276T polymorphisms were associated with significantly reduced plasma levels of ADPN in DPN and NDPN groups, compared to the NC group (P<0.001). Significant difference in ADPN plasma levels were also observed between TT, TG and GG genotypes of T45G and G276T polymorphisms. Our results indicate that the T allele in +45T/G and +276G/T polymorphisms is correlated with an elevated risk of DPN in T2DM patients. Haplotype analysis showed that GG and GT haplotypes showed a negative relationship with DPN, while TG haplotype positively correlated with risk of DPN in T2DM patients (all P<0.05). CONCLUSION Our results show that T45G and G276T polymorphisms of ADPN are associated with a significantly elevated risk of DPN in T2DM patients, likely by down-regulating ADPN serum level.

Helicobacter pylori infection might have a potential role in hepatocyte ballooning in nonalcoholic fatty liver disease. J Gastroenterol 2015; 50:996-1004. [PMID: 25622927 DOI: 10.1007/s00535-015-1039-2] [Citation(s) in RCA: 51] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2014] [Accepted: 01/04/2015] [Indexed: 02/07/2023]
Abstract
BACKGROUND Clinical data regarding Helicobacter pylori (H. pylori) infection in nonalcoholic fatty liver disease (NAFLD) are limited. The aim was to evaluate H. pylori infection in patients with NAFLD and its association with disease severity. METHODS One hundred and thirty patients with biopsy-proven NAFLD [43 with nonalcoholic fatty liver (NAFL) and 87 with nonalcoholic steatohepatitis (NASH)] were recruited for blood samples for anti-H. pylori immunoglobulin G (IgG) and standard biochemical tests were obtained after overnight fasting. Glucose tolerance was evaluated by 75-g oral glucose tolerance test. Liver biopsies were scored for NAFLD activity score (NAS), fibrosis and iron deposits. RESULTS H. pylori IgG seropositivity was found in 40 % of patients overall. The prevalence of NASH was significantly higher in the patients with H. pylori IgG seropositivity (81 %) than in those without (58 %, p = 0.008). Glucose intolerance was similar between the two groups. The total NAS and the grade of hepatocyte ballooning were higher in the patients with H. pylori IgG seropositivity than in those without, while the hepatic iron grade was lower in the patients with H. pylori IgG seropositivity than in those without. H. pylori infection (p = 0.030), female gender (p = 0.029), and NAFIC score ≥ 2 points (p < 0.001) could independently predict NASH in logistic regression analysis, independent of age, obesity and glucose tolerance. CONCLUSION The association of H. pylori seropositivity with hepatocyte ballooning suggests that H. pylori infection may represent another contributing factor in the progression from NAFL to NASH. Eradicating H. pylori infection may have therapeutic prospects in NASH treatment.

Abstract
BACKGROUND AND AIM To evaluate a high effective and practical regimen for the eradication of Helicobacter pylori infection. PATIENTS AND METHODS The 298 patients with H. pylori infection, diagnosed by biopsies performed during the endoscopy, were randomized into two groups. Group 1: Treated for one week with a combination of omeprazole, amoxicillin, and clarithromycin (OAC), named by OAC-1 group (n = 143); Group 2: OAC-2 group (n = 155) treated for two weeks with OAC. The OAC-1 group was treated with triple therapy of omeprazole 20 mg, amoxicillin 1000 mg, and clarithromycin 500 mg bid for 1 week. OAC-2 group was treated likewise, but for two weeks. A 13C-urea breath test was used to monitor H. pylori after four to eight weeks following therapy. RESULTS The eradication of infection was 55% and 68% in the OAC-1 and OAC-2 groups, respectively. Moreover, the eradication rates in the two groups were 63% and 75%, respectively. Compared with the OAC-1 group, the efficacy of treatment in the OAC-2 group is significantly higher (P < 0.05). CONCLUSION Two-week OAC regimen yields a higher eradication rate of H. pylori, which might be a practical regimen for the eradication of H. pylori.

Abstract
Korea and Japan show the highest incidence of gastric cancer and Helicobacter pylori infection. New 2013 guidelines on H. pylori infection differ between the two countries with regard to the indications for H. pylori eradication, diagnostic methods, and treatment regimens. Indications for eradication in Korean guideline focus on specific diseases such as peptic ulcer disease, low-grade gastric mucosa-associated lymphoid tissue lymphoma, and after resection of early gastric cancer, while Japanese guideline includes all H. pylori-associated gastritis for the prevention of dissemination. With regard to the diagnosis, either noninvasive or invasive method (except for bacterial culture) is recommended in Korea, while two noninvasive tests including serum anti-H. pylori IgG antibody level are preferred in Japan. As for the treatment regimens, second-line treatment (quadruple bismuth-containing regimen) is recommended without first-line triple therapy in areas of high clarithromycin resistance in Korea. However, there is no bismuth-based second-line treatment in Japan, and the Japanese regimen consists of a lower dose of antibiotics for a shorter duration (7 days). Such discrepancies between the two countries are based not only on the differences in the literature search and interpretation, but also on the different approvals granted by the national health insurance system, manufacturing process of the antibiotics, and diagnostic techniques in each country. Collaborations are required to minimize the discrepancies between the two countries based on cost-effectiveness.

Abstract
Helicobacter pylori (H. pylori) infects more than half of the world’s human population, but only 1% to 3% of infected people consequently develop gastric adenocarcinomas. The clinical outcome of the infection is determined by host genetic predisposition, bacterial virulence factors, and environmental factors. The association between H. pylori infection and chronic active gastritis, peptic ulcer disease, gastric cell carcinoma, and B cell mucosa-associated lymphoid tissue lymphoma has been well established. With the exception of unexplained iron deficiency anemia and idiopathic thrombocytopenic purpura, H. pylori infection has no proven role in extraintestinal diseases. On the other hand, there is data showing that H. pylori infection could be beneficial for some human diseases. The unpredictability of the long-term consequences of H. pylori infection and the economic challenge in eradicating it is why identification of high-risk individuals is crucial.

Abstract
Background. Increased insulin resistance is an extragastrointestinal manifestation of Helicobacter pylori (HP) infection. HP changes the level of inflammatory markers and cytokines and changes the adipocyte function by altering the adiponectin level. Given the high prevalence of HP and diabetes in our society, we evaluated the association between HP and serum adiponectin level. In this cross-sectional study, 211 diabetic patients under treatment other than insulin were studied. These patients were divided into two groups of HP+ and HP− based on their HP IgG antibody serology and their blood adiponectin levels were measured. Data was analyzed using independent t-test, Chi-square test, and Fisher's exact test. Results. Seventy-two patients with an average age of 51.56 ± 8.34 years were HP− and 139 patients with an average age of 50.35 ± 9.01 years were HP+. The mean serum adiponectin level in HP− and HP+ groups was 4.54 ± 5.43 and 5.64 ± 3.88 ng/mL, respectively. Insulin resistance degree was significantly higher in HP+ group (HP− = 3.160 ± 3.327 versus HP+ = 4.484 ± 3.781, P = 0.013) but no significant difference was found between the mean serum adiponectin level in HP− and HP+ groups (P = 0.140). Conclusions. Although the insulin resistance degree was significantly higher in HP+ diabetic patients, no significant relationship was found between HP infection and serum levels of adiponectin.
