The Prevalence of Gallstone Disease Is Significantly Lower in Natives than in Migrants of Jeju Island

Liver Function-Related Indicators and Risk of Gallstone Diseases-A Multicenter Study and a Systematic Review and Meta-Analysis

Purpose of the study: We aim to examine the association between liver function-related indicators and gallstone disease (GSD) risk. Study design: The subjects who participated in the China Multicenter Physical Examination Cohort (CMPEC) were enrolled. Relative odds ratios (ORs) with 95% CIs and standardized mean differences (SMDs) were applied to investigate the effect of liver function-related indicators and GSD risk. Moreover, a systematic review and meta-analysis were conducted until July 2021. Additionally, the results in the CMPEC and the systematic review and meta-analysis were combined by meta-analysis. Finally, the results were validated by a cohort study of the UK Biobank (UKB). Results and conclusions: Totally, 369,931 subjects in CMPEC were included in the study. A total of 28 publications were incorporated into the systematic review and meta-analysis. The pooled analysis suggested that aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total protein (TP), and low albumin (ALB) were positively associated with the risk of GSD. Meanwhile, GSD present to have higher AST, ALT, gamma-glutamyl transferase (GGT), total bilirubin (TBil), globulin (G), and ALP levels and relatively lower TP and ALB levels than the healthy participants. These results were consistent when stratified by the study design, geographic background, and study quality. Only the association between ALP and GSD risk was validated in the UKB cohort. This study suggests liver function indicators were associated with GSD risk. The results may provide the basis for exploring the etiology of GSD and may help clinicians identify high-risk subjects. Trial Registration: PROSPERO (CRD42020179076).

Retrospective Study of the Prevalence and Associated Factors of Gallbladder Polyps among Residents of Two Korean Cities

Background/Aims: Well-known risk factors for gallbladder polyps include metabolic syndrome, age, and dyslipidemia. Jeju Island is approximately 80 km from the Korean peninsula and is divided into two administrative regions (Jeju City and Seogwipo City), with Mount Halla intervening in the center. Jeju City has higher employment and birth rates than Seogwipo City. Age and alcohol consumption differ between the two regions, and these factors may affect the prevalence of gallbladder polyps (GBPs). Therefore, we investigated the prevalence of GBPs and compared various factors, including alcohol consumption habits and age, associated with GBPs among residents in the two regions. Methods: This study included 21,734 residents who visited the Health Screening and Promotion Center of Jeju National University Hospital between January 2009 and December 2019. We investigated the prevalence and associated factors of GBPs among residents of Jeju City and Seogwipo City. Results: The prevalence of GBPs in Jeju City and Seogwipo City was 9.8% and 8.9% (p = 0.043), respectively. The mean age and rate of high-risk alcohol intake were higher in Seogwipo City. The mean body mass index and levels of fasting blood glucose, total cholesterol, low-density lipoprotein cholesterol, aspartate aminotransferase, gamma-glutamyl transferase, and alkaline phosphatase were lower in Jeju City. Conclusions: This study demonstrated a significant difference in GBP prevalence between the two regions of Jeju Island. Age and alcohol consumption might contribute to this difference; however, further prospective cohort studies are warranted to confirm our findings.

Cholecystectomy reduces the risk of myocardial and cerebral infarction in patients with gallstone-related infection

We compared the risk of myocardial infarction (MI) or cerebral infarction (CI) in patients with or without-gallstone-related infection (GSI) and change in the risk following cholecystectomy. GSI (n = 84,467) and non-GSI (n = 406,800) patients with age- and sex-matched controls (n = 4,912,670) were identified from Korean population based data. The adjusted hazard ratios (aHRs) of MI or CI were analyzed in both groups treated with or without cholecystectomy. Subgroup analysis was performed for both sexes and different ages. The risk of MI or CI was higher in the GSI group than in the non-GSI group (aHR for MI; 1.32 vs. 1.07, aHR for CI; 1.24 vs. 1.06, respectively). The risk reduction rate of MI following cholecystectomy was 11.4% in the GSI group, whereas it was 0% in the non-GSI group. The risk of CI after cholecystectomy was more reduced in the GSI group than in the non-GSI group (16.1% and 4.7%, respectively). The original risk of MI or CI in patients with gallstones and risk reduction rates following cholecystectomy were higher in females and younger patients than in males and older patients. Increased risk of MI or CI and greater risk reduction following cholecystectomy were seen in patients with GSI.

Epidemiological survey to determine the prevalence of cholecystolithiasis in Uyghur, Kazakh, and Han Ethnic Groups in the Xinjiang Uyghur Autonomous Region of China: cross-sectional studies

Background

This study was performed to understand the prevalence of and possible risk factors for cholecystolithiasis in Uyghur, Kazakh, Han, and other ethnic groups in the Xinjiang Uyghur autonomous region of China.

Methods

Subjects were enrolled using typical case sampling and multistage stratified random sampling. We collected epidemiological data regarding cholecystolithiasis using a standard questionnaire of risk factors for gallbladder disease in Xinjiang. The subjects completed the questionnaire and underwent an abdominal ultrasound examination of the liver and gallbladder.

Results

This study included 5454 Xinjiang residents aged ≥ 18 years. The prevalence of cholecystolithiasis was 15% (11.3% in men and 17.1% in women), and the sex difference was statistically significant (male-to-female odds ratio [OR] 1.867; p < 0.001). The cholecystolithiasis prevalence was also significantly different among the Han, Uyghur, Kazakh, and other ethnic groups (13.1%, 20.8%, 11.5%, and 16.8%, respectively; p < 0.001). The prevalence of cholecystolithiasis in northern Xinjiang was 13.5% and that in southern Xinjiang was 17.5%; this difference was also statistically significant (OR 1.599; p < 0.001). Across all ethnic groups, the cholecystolithiasis prevalence significantly increased with age (all p < 0.01) and body mass index (BMI) (all p < 0.01). A multivariate logistic regression analysis indicated that cholecystolithiasis prevalence was associated with sex, age, BMI, smoking, diabetes, fatty liver disease, and geographical differences between northern and southern Xinjiang.

Conclusions

The prevalence of cholecystolithiasis was significantly higher in the Uyghur ethnic group than in the Han, Kazakh, and other ethnic groups; in women than in men; in southern Xinjiang than in northern Xinjiang; in patients with fatty liver disease; and increased with age and BMI. Our findings could provide a theoretical basis for the formulation of control measures for cholecystolithiasis.

Physical activity can reduce the prevalence of gallstone disease among males: An observational study

Several previous studies have reported that physical activity (PA) levels can independently affect the prevalence of gallstone disease (GD) in Western countries. However, this association has not been reported in Eastern countries. Therefore, this study aimed to determine whether PA is an independent determinant of GD prevalence in a Korean population, according to the World Health Organizations Global Recommendations on PA for Health.A total of 8908 subjects who completed a questionnaire underwent medical examination and ultrasound scanning at the Health Promotion Center of the Jeju National University Hospital between January 2009 and December 2018. GD and fatty liver disease were diagnosed by abdominal ultrasound. Biochemical parameters and body mass index were determined, and metabolic syndrome status, age, and PA levels were extracted from medical records. Univariate and multivariate analyses were performed to identify independent factors affecting GD.The estimated rates of PA and GD among male subjects were 23.7% and 4.6%, whereas the rates among females were 18.4% and 4.2%, respectively. Multivariate analysis suggested that no PA, old age, and higher aspartate aminotransferase level in males and nonalcoholic fatty liver disease status in females were independent factors affecting GD.In our study, PA was associated with a reduction in GD among males but not females.

Prevalence and risk factors for gallstone disease: A population-based cross-sectional study

OBJECTIVE

To explore the prevalence of and risk factors for gallstone disease in Shanghai, China.

METHODS

A population-based cross-sectional study was conducted in Shanghai between 2016 and 2017. Using a three-stage stratified sampling strategy, 4009 participants (1753 men and 2256 women) from 10 districts were enrolled.

RESULTS

The overall prevalence of gallstones was 6.83% (6.22% for men vs 7.31% for women, P = 0.173). According to the multivariate analysis, individuals aged ≥40 years (odds ratio [OR] 3.058, 95% confidence interval [CI] 2.110-4.433, P < 0.001), hypertension (OR 1.479, 95% CI 1.076-2.034, P = 0.016), thyroid disease (OR 1.409, 95% CI 1.029-1.928, P = 0.032), a family history of gallstones (OR 2.234, 95% CI 1.362-3.662, P = 0.001) and a waist-to-height ratio ≥0.5 (OR 1.656, 95% CI 1.197-2.292, P = 0.002) had an increased risk of developing gallstones. The risk of gallstone disease was 2.232 (95% CI 1.167-4.268, P = 0.015) times higher in individuals with elevated C4 levels than in those with normal C4 levels. Diabetes (OR 4.144, 95% CI 1.171-14.671, P = 0.028) was a risk factor for the formation of gallstones with diameters ≥1 cm, and men were more susceptible to develop multiple stones (OR 2.356, 95% CI 1.321-4.200, P = 0.004).

CONCLUSION

Individuals aged ≥40 years, with a history of hypertension and familial gallstones, a high waist-to-height ratio, thyroid disease and high C4 levels were related to an increased risk of gallstone disease.

The grade of nonalcoholic fatty liver disease is an independent risk factor for gallstone disease: An observational Study

There have been reports linking nonalcoholic fatty liver disease (NAFLD) with gallstone disease (GD) owing to shared risk factors. However, there are no reported associations between the different NAFLD grades and GD. This study aimed to determine whether NAFLD grade is an independent risk factor for GD in a Korean population.This study enrolled 7886 participants who completed a questionnaire and underwent medical examination and ultrasound scanning at the Health Promotion Center of Jeju National University Hospital in Korea, from January 2009 to December 2017. Fatty liver grading and presence of gallstones were investigated using abdominal ultrasound. Body mass index and biochemical parameters were measured, and age, sex, and metabolic syndrome status were collected from medical records. Univariate and multivariate analyses were performed to identify risk factors for GD.The estimated prevalences of NAFLD and GD were 40.6% and 4.5%, respectively. In the univariate analysis, factors associated with GD were age; NAFLD; presence of metabolic syndrome; and levels of fasting blood glucose, high-density lipoproteins, aspartate aminotransferase, and alanine aminotransferase. Multivariate logistic regression analysis revealed older age and higher NAFLD grade as independent risk factors for GD.Older age and higher grade of NAFLD were independent risk factors for GD in our cohort. There was a strong correlation between grade of NAFLD on abdominal ultrasonography and GD.

Gallstone disease and its correlates among patients attending teaching hospital of North India

Background

Gallstone disease (GSD) represents a significant burden for healthcare systems worldwide and is one of the most common disorders among patients presenting to emergency rooms with abdominal discomfort.

Aim and Objective

This study was aimed to find correlates (demographic, dietary, and behavioral) of GSD in patients attending teaching hospital in North India.

Methodology

A case-control study was conducted from January 2013 to December 2013 among subjects attending outpatient department of general surgery in a teaching hospital. Data collection for both cases and controls was done on a self-designed pretested "interview schedule" which assessed the sociodemographic profile, personal history, medical history, comorbidities, physical examination including anthropometry, and dietary intakes. To measure the strength of association, odds ratio (OR) was calculated. Binary logistic regression was used for multivariate analysis.

Results

A total of 120 cases and the same number of age- and sex-matched controls were included in final analysis. In binary logistic regression, maximum association was seen with physical inactivity [OR 3.93, confidence interval (CI): 1.98-7.78] followed by current consumption of smokeless tobacco (OR 3.65, CI: 1.65-8.09), current smoking (OR 2.69, CI: 1.13-6.37), nonvegetarian diet (OR 3.10, CI: 1.65-5.83), and fat intake (OR 2.14, CI: 1.14-4.02). Current alcohol consumption (OR 0.90, CI: 0.41-1.98), high waist-hip ratio (OR 1.54, CI: 0.67-3.56), and intake of fruits and green leafy vegetables (OR 1.86, CI: 0.61-5.61) were not significantly associated with GSD.

Conclusion

Physical inactivity, smokeless tobacco, nonvegetarian diet, current smoking, high fat intake, and family history were found to be risk factors for the development of GSD.
