Background
Various studies reported the relationship between Helicobacter pylori (H pylori) and vitamin D, but there is some controversy around that. This study aimed to conduct a meta‐analysis to clarify the relationship between vitamin D and H pylori infection, and vitamin D and H pylori eradication.

Methods
Articles published until June 1, 2019, in the PubMed, MEDLINE, and EMBASE databases with English‐language medical studies were searched. According to the inclusion criteria, relevant statistical data were extracted to Microsoft Excel and analyzed by STATA15.1.

Results
Ten articles were finally included. It was demonstrated that average 25(OH)D level in H pylori‐positive patients was lower than H pylori‐negative (SMD = −0.53 ng/mL, 95% CI = (−0.91, −0.16 ng/mL)). For H pylori eradication individuals, the result showed that average 25(OH)D level in H pylori successful eradication individuals was higher than unsuccessful (SMD = 1.31 ng/mL, 95% CI = [0.60, 2.02 ng/mL]).
In addition, individuals with vitamin D deficiency had lower H pylori eradicate rate (OR = 0.09, 95% CI = [0.02, 0.41]).
Sensitivity analysis showed that the meta‐analysis results were stable and reliable.

Conclusions
Vitamin D was a protective factor to H pylori infection. Moreover, vitamin D can improve the success rate of H pylori eradication.

BACKGROUND/AIM:
Many studies have investigated risk factors other than antibiotic resistance linked to Helicobacter pylori (H. pylori) eradication failure. The aim of this study was to study the effect of serum levels of 25-hydroxy-vitamin D (25OHD) on eradication rates of H. pylori infection.

METHODS:
This study included 150 patients diagnosed with H. pylori gastritis using magnifying narrow-band imaging endoscopy supported by stool antigen test. Serum 25-OH vitamin D levels were measured via the Enzyme-Linked Immune Sorbent assay (ELISA) method before starting eradication therapy of H. pylori infection. All patients were treated with clarithromycin-based triple therapy for 14 days. H. pylori eradication was determined via a stool antigen test performed 4 weeks after the end of therapy. According to the serum level of 25-OH vitamin D levels, the patients were divided into two groups: group I (sufficient) had a vitamin D level of ≥20 ng/mL, while group II (deficient) had a vitamin D level of <20 ng/mL.

RESULTS:
Our results revealed that eradication was successful in 105 (70%) patients and failed in 45 (30%) patients. The mean 25[OH]D level was significantly lower in the eradication failure group compared to the successful treatment group (14.7 ± 4.5 vs 27.41 ± 7.1; P < 0.001).
Furthermore, there were significantly more patients with deficient 25[OH]D levels in the failed treatment group, 30 (66.6%), compared to the successful group, 10 (9.5%) (P < 0.001).

CONCLUSIONS:
Our results demonstrated that 25-OH vitamin D deficiency may be considered a risk factor related to eradication failure of H. pylori infection. In addition, a further randomized trial to evaluate the effect of vitamin D supplementation in H. pylori eradication is mandatory.

BACKGROUND:
Helicobacter pylori eradication therapy improves the healing of various gastro-duodenal diseases such as chronic gastritis and peptic ulcer, and also reduces gastric cancer incidence. Several studies have reported on risk factors other than antibiotic resistance related to Helicobacter pylori eradication failure.

OBJECTIVES:
In this study, we aimed to investigate whether or not the serum levels of 25-hydroxy-vitamin D (25(OH)D) influence eradication rates of H.pylori.

MATERIAL AND METHODS:
220 patients diagnosed with H.pylori gastritis using endoscopic biopsy had their 25-OH vitamin D levels measured via the electrochemiluminescence method before beginning eradication therapy of H.pylori. Gastric biopsies obtained at endoscopy were examined for H.pylori strains and histopathologic findings. All patients were treated with bismuth-containing quadruple therapy for 14 days. H.pylori eradication was determined via the 14C-urea breath test performed 4 weeks after the end of therapy. Based on the 25-OH vitamin D levels, the patients were divided into 2 groups: group 1 (deficient) had a vitamin D level of <10 ng/mL, while group 2 (sufficient) had a vitamin D level of ≥10 ng/ mL.

RESULTS:
Eradication was successful in 170 (77.2%) patients and failed in 50 (22.7%) patients. The prevalence of 25(OH)D deficiency was 30.5%. Mean 25(OH)D levels were significantly lower in the eradication failure group compared to the successful treatment group (9.13 ±4.7 vs 19.03 ±8.13; p = 0.001). There were significantly more patients with deficient 25(OH)D levels in the failed treatment group compared to the successful treatment group (p = 0.001).

CONCLUSIONS:
Our findings suggest that 25-OH vitamin D deficiency may be considered a risk factor related to eradication failure of H.pylori, which may lead to a need for supplementation of vitamin D before eradication of H.pylori.

BACKGROUND:
Vitamin D deficiency is known to cause increased predisposition to various infectious diseases and the addition of vitamin D to antimicrobial treatment may improve treatment responses. However, the relationship between vitamin D and Helicobacter pylori (H. pylori) remains to be determined.

AIMS: To assess the association between vitamin D deficiency and H. pylori infection.

METHODS:
This cross-sectional study included patients aged 65 and over, who underwent gastroscopy and had gastric biopsy performed between 2010 and 2017. Of the 441 patients, 254 had available 25-hydroxyvitamin D level results and were included in the analyses. Patients were categorized into H. pylori (+) and H. pylori (-) groups, according to histopathological examination results of gastric biopsies. Serum 25(OH) vitamin D levels less than 20 ng/mL were defined as vitamin D deficiency.

RESULTS:
Of all patients, 43 were H. pylori (+) and 211 were H. pylori (-). More patients had vitamin D deficiency (< 20 ng/mL) in the H. pylori (+) group than the H. pylori (-) group (86% vs 67.3%, p = 0.014). The proportion of H. pylori (+) patients decreased across increasing quartiles of 25(OH) vitamin D levels (p for trend = 0.010). In multivariable logistic regression analysis, vitamin D deficiency was associated with increased odds of H. pylori infection after adjustment for age, gender, and Charlson Comorbidity Index (OR = 3.02, 95% CI 1.19-7.69, p = 0.020).

CONCLUSION:
Vitamin D deficiency can be associated with increased risk of H. pylori infection. The potential protective effect of vitamin D against H. pylori infection and its possible role in the treatment of H. pylori should be evaluated in prospective trials.

The associations between Helicobacter pylori infection, serum vitamin D level, and metabolic syndrome (MS) are controversial. The present community-based study aimed to investigate the effect of H pylori infection and serum vitamin D deficiency on MS development.Individuals from the northeastern region of Taiwan were enrolled in a community-based study from March, 2014 to August, 2015. All participants completed a demographic survey and underwent the urea breath test (UBT) to detect H pylori infection as well as blood tests to determine levels of vitamin D, adiponectin, leptin, and high-sensitivity C-reactive protein. The ATP III criteria for MS were used in this study. A total of 792 men and 1321 women were enrolled. The mean age was 56.4 ± 13.0 years. After adjusting for age and sex, the estimated odds of MS development for a UBT-positive subject were 1.503 (95% confidence interval CI: 1.206-1.872, P < 0.001) when compared to a UBT-negative subject.
For participants with vitamin D deficiency (<20 ng/mL), the odds of MS development were 1.423 (95% CI: 1.029-1.967, P = 0.033) when compared to those with sufficient vitamin D level (>30 ng/mL).
For participants with both H pylori infection and vitamin D deficiency, the odds of MS development were 2.140 (95% CI: 1.348-3.398, P = 0.001) when compared to subjects without H pylori infection and with sufficient vitamin D levels.H pylori infection and vitamin D deficiency could be predictors of MS.
For individuals with both H pylori infection and vitamin D deficiency, the odds of MS development were 2.140 when compared to individuals without H pylori infection and with sufficient vitamin D levels.
