Prevalence and Risk Factors for Helicobacter Pylori Infection among Healthy Inhabitants in Northern Jakarta, Indonesia

The intake of solid fat and cheese may be associated with a reduced risk of Helicobacter pylori infection status: a cross-sectional study based on NHANES 1999-2000

BACKGROUND

Diet plays an important role in Helicobacter pylori (HP) infection, and our objective was to investigate potential connections between dietary patterns, specific food groups, and HP infection status in U.S. adults.

METHODS

The data for this study was obtained from the NHANES (National Health and Nutrition Survey) database for the year 1999-2000. This cross-sectional study involved the selection of adults aged 20 years and older who had undergone dietary surveys and HP testing. Factor analysis was employed to identify dietary patterns, and logistic regression models were utilized to assess the association between these dietary patterns and specific food groups with HP infection status.

RESULT

Based on the inclusion and exclusion criteria, our final analysis included 2,952 individuals. The median age of participants was 51.0 years, and 48.7% were male. In the study population, the overall prevalence of HP infection was 44.9%. Factor analysis revealed three distinct dietary patterns: High-fat and high-sugar pattern (including solid fats, refined grains, cheese, and added sugars); Vegetarian pattern (comprising fruits, juices, and whole grains); Healthy pattern (encompassing vegetables, nuts and seeds, and oils). Adjusted results showed that the high-fat and high-sugar pattern (OR = 0.689, 95% CI: 0.688-0.690), vegetarian pattern (OR = 0.802, 95% CI: 0.801-0.803), and healthy pattern (OR = 0.717, 95% CI: 0.716-0.718) were all linked to a lower likelihood of HP infection. Further analysis of the high-fat and high-sugar pattern revealed that solid fats (OR = 0.717, 95% CI: 0.716-0.718) and cheese (OR = 0.863, 95% CI: 0.862-0.864) were protective factors against HP infection, while refined grains (OR = 1.045, 95% CI: 1.044-1.046) and added sugars (OR = 1.014, 95% CI: 1.013-1.015) were identified as risk factors for HP infection.

CONCLUSION

Both the Vegetarian pattern and the Healthy pattern are associated with a reduced risk of HP infection. Interestingly, the High-fat and High-sugar pattern, which is initially considered a risk factor for HP infection when the score is low, becomes a protective factor as the intake increases. Within this pattern, animal foods like solid fats and cheese play a protective role, while the consumption of refined grains and added sugars increases the likelihood of HP infection.

Association of Helicobacter pylori in Children With Self-Hand Hygiene, Maternal Hand Hygiene, Cooking, and Feeding Practices

Background and objective Helicobacter pylori infection is widely prevalent, but its route of transmission is not clear. Person-to-person transmission seems plausible, with hand hygiene being one of the many factors that play a role. The objective of this study was to study the effect of the children's and their mother's hand hygiene and feeding practices on the prevalence of H. pylori in children. Methodology This cross-sectional study involved 475 children and their mothers. A questionnaire was administered to mothers to gather information about maternal hygiene practices, specifically handwashing before food handling and after using the toilet. Additionally, both mothers and children underwent assessments for nail length (whether cut or uncut) and the presence or absence of dirt under their nails, if nails were uncut. The association of these parameters with H. pylori seropositivity in children was comprehensively examined. Furthermore, children were divided into two distinct groups: a younger age group (one month to two years and 11 months) and an older age group (three years to 15 years). For one specific parameter - the presence of dirt under mothers' nails (i.e., if nails were uncut) - the association was further analyzed separately within these age groups. The chi-square test was applied to all variables. P < 0.05 was considered significant Results The association of all variables with H. pylori seropositivity in children was tested. Association with H. pylori seropositivity was not present in mothers with uncut nails (P = 0.050315), mothers with uncut nails harboring dirt under their nails within the entire sample of 475 mothers (P = 0.39476), and mothers with uncut nails harboring dirt under their nails in the older age group (three years to 15 years) of children (P = 0.760071). Association with H. pylori seropositivity was present in mothers with dirt under their uncut nails belonging to the younger age group of children (one month to two years and 11 months (P = 0.014127) and mothers who did not wash their hands before food handling (P = 0.003032) and after using the toilet (P = 0.003082). In all 475 children, association with H. pylori seropositivity was significant with dirt under the uncut nails of children (P = 0.015194) and was not significant for children with merely grown nails but not harboring dirt under them (P = 0.355967).  Conclusions Mother-to-child transmission is one of the likely routes of transmission of H. pylori, and poor hand hygiene seems to play a major role in this process.

Overview of Helicobacter pylori Infection in Indonesia: What Distinguishes It from Countries with High Gastric Cancer Incidence?

Helicobacterpylori infects more than half the human population. However, the prevalence in Indonesia is low, as is the prevalence of gastric cancer. Hence, it could be instructive to compare these prevalence rates and their determining factors with those of countries that have high gastric cancer incidence. Ethnicity and genetic characteristics of H. pylori are important determinants of the H. pylori infection rate in Indonesia. The infection rate is higher in Bataknese, Papuans and Buginese than in Javanese, the predominant ethnic group. Ethnicity is also an important determinant of the genetic characteristics of H. pylori. Analysis of CagA in the EPIYA segment showed that the predominant genotypes in Papuans, Bataknese and Buginese are ABB-, ABD- and ABC-type CagA, respectively. Meanwhile, in the countries with high gastric cancer incidence, almost all strains had East Asian type CagA. An antibiotic susceptibility evaluation showed that the standard triple therapy can still be used with caution in several cities. There is a very high rate of resistance to second-line regimens such as levofloxacin and metronidazole. Recent studies have shown that furazolidone, rifabutin and sitafloxacin are potential alternative treatments for antibiotic-resistant H. pylori infection in Indonesia. Rather than focusing on early detection and eradication as in countries with high gastric cancer prevalence, countries with low gastric cancer prevalence should focus on screening the several groups that have a high risk of gastric cancer.

Comparison of 10-Day Course of Triple Therapy Versus 14-Day Course for Eradication of Helicobacter pylori Infection in an Indonesian Population: Double-Blinded Randomized Clinical Trial

Objective:

The aim of this study was to compare the effectiveness of 10-day course of triple therapy versus a 14-day course in the treatment of H.pylori infection in an Indonesian population.

Methods:

A double-blinded randomized clinical trial was included patients, Indonesian population, with H.pylori infection conducted in Cipto Mangunkusumo Hospital, Jakarta; Cilincing District General Hospital, Jakarta; and West Nusa Tenggara General Hospital, Mataram, during October 2016 - April 2017. Patients were randomized to be given triple therapy as Rabeprazole 20 mg, Amoxicillin 1,000 mg, and Clarithromycin 500 mg twice daily, for 14 days or 10 days plus 4 days placebo. Eradication was evaluated with UBT at least 4 weeks after completion the therapy.

Results:

A total of 75 patients (38 in the 14-day group and 37 in the 10-day group) were included to the study. In the intention-to-threat analysis, eradication rate was 67.6% (95% CI. 52.5%-82.6%) for the 10-day group versus 86.8% (95% CI. 76.0%-97.5%) for the 14-day group (p = 0.046), whereas per protocol analysis obtained 73.5% (95% CI. 58.6%-88.3%) for the 10-day versus 91.9% (95% CI. 84.1%-99.6%) in the 14-day group (p = 0.039). Adverse events were not significantly different between the two groups.

Conclusion:

A 14-day course was more effective than 10-day course of triple therapy as first-line for eradication of H.pylori infection in an Indonesian population.

Prevalence of Helicobacter Pylori Infection in Dyspeptic Patients in Andkhoy Afghanistan

Background: The prevalence of Helicobacter pylori (H. pylori) infection is reported to be more than 50% worldwide. It has been associated with peptic ulcer disease, gastric carcinoma, and mucosal-associated lymphoid tissue lymphoma. The seroprevalence of H. pylori varies greatly among societies and geographical locations. The objective of this study was to determine the seroprevalence and factors associated with H. pylori infection among dyspeptic patients in Afghanistan. Materials and Methods: This cross-sectional study was designed to determine the seroprevalence of H. pylori among dyspeptic patients in an outpatient clinic in Andkhoy, Afghanistan from January 2017 to April 2017. Data were obtained from patients using a questionnaire, including socio-demographic data and history of smoking and dyspeptic symptoms. Serum samples were also collected from the patients and tested for H. pylori antibodies using the enzyme-linked immunosorbent assay. Results: A total of 152 patients with dyspepsia were included in the analysis; 59 were men (40.0%), and 93 were women (60.0%). The overall seroprevalence of H. pylori was 75.6%. The predictor of seroprevalence of H. pylori was found to be illiteracy (odds ratio [OR] 4.99, 95% confidence interval [CI] 1.03¬24.17), epigastric pain (OR 12.01, 95% CI 3.56- 40.52), and rural population (OR 9.66, 95% CI 3.36- 27.82). There was an inverse association between employed status and seroprevalence of H. pylori (OR 0.08, 95% CI 0.01- 0.52). Conclusions: The seroprevalence of H. pylori was high among patient with dyspepsia in an outpatient clinic in Afghanistan. Illiteracy, unemployment and rural populations, and epigastric pain were significantly associated with H. pylori infection.
