Prevalence of Gall Bladder Stones among Type 2 Diabetic Patients in Benghazi Libya: A Case-control Study

The Correlation between Islet β Cell Secretion Function and Gallbladder Stone Disease: A Retrospective Study Based on Chinese Patients with Newly Diagnosed Type 2 Diabetes Mellitus

BACKGROUND

This study aimed to analyze the correlation between islet β cell function and gallbladder stone (GBS) in newly diagnosed type 2 diabetes mellitus (T2DM) patients.

METHODS

A total of 438 newly diagnosed T2DM patients in Peking University International Hospital from January 2017 to August 2022 were retrospectively analyzed and divided into a non-GBS group and a GBS group.

RESULTS

(1) The homeostasis model assessment of the insulin resistance (HOMA-IR) of the GBS group was higher than that of the non-GBS group (p < 0.05), while the homeostasis model assessment of β cell (HOMA-β), disposition index (DI0), and Matsuda index of the GBS group were lower than those of the non-GBS group (all p < 0.05). (2) For male patients, HOMA-IR is an independent risk factor for GBS (OR = 2.00, 95% CI:1.03, 3.88, p < 0.05), and the Matsuda index value is a protective factor for GBS (OR = 0.76, 95% CI:0.60, 0.96, p < 0.05). For female patients, HOMA-IR is an independent risk factor for GBS (OR = 2.80, 95% CI:1.03, 7.58, p < 0.05) and the Matsuda index value is a protective factor for GBS (OR = 0.59, 95% CI:0.39, 0.90, p < 0.05). (3) For male patients, the area under curve (AUC) for predicting GBS was 0.77 (95% CI 0.67, 0.87), with a specificity of 75.26%, a sensitivity of 80.00%, and an accuracy of 75.64%. For female patients, the AUC for predicting GBS was 0.77 (95% CI 0.63, 0.88), with a specificity of 79.63%, a sensitivity of 71.43%, and an accuracy of 78.69%.

CONCLUSIONS

Insulin resistance may be an independent risk factor for the incidence of GBS in patients with newly diagnosed T2DM, both male or female, which provides a new clinical basis and research direction for the prevention and treatment of GBS in patients with T2DM. This study has established a predictive model of GBS in T2DM and found it to be accurate, thus representing an effective tool for the early prediction of GBS in patients with T2DM.

Sonographic Evaluation of the Gallbladder in Adult Patients With Type 2 Diabetes Mellitus

Introduction and aim: Diabetes mellitus (DM) is one of the most common non-communicable diseases worldwide. Diabetics with autonomic neuropathy tend to have larger gallbladder (GB) with poor contraction after fatty meals predisposing them to gallstones and cholecystitis. This may be prevented and treated if detected early using ultrasound. This study sonographically evaluated the GB in adults with type 2 diabetes and compared the findings with a non-diabetic age and sex-matched control group.

Methods: In this case-control study, 120 patients with type 2 diabetes and 120 non-diabetic controls between the ages of 18 and 80 years at National Hospital Abuja had their GB evaluated after eight hours of overnight fast using B-mode ultrasound. The data were analyzed using IBM SPSS version 20.0 (Armonk, NY: IBM Corp.) and presented in tables.

Result: There were 60 males and 60 females with mean ages of 53.3 and 52 years for the cases and controls, respectively. The average fasting gallbladder volume (FGBV) in diabetics (34.51 + 3.16cm³) was higher than that of controls (27.17 + 1.25cm³). Eleven (9.2%) diabetics had gallstone (GS), while none was detected in controls. The GB wall thickness was significantly higher in diabetics than in the controls (0.28 ± 0.06 cm vs 0.25 ± 0.04 cm).

Conclusion: A significant proportion of type 2 diabetics had higher FGBV, GB wall thickness, and presence of gallstone compared to the non-diabetic controls. B-mode ultrasound is a very important non-invasive and accurate tool for detecting these changes early.

Prevalence of gallstone disease in patients with type 2 diabetes and the risk factors in North Indian population: a case control study

BACKGROUND

Age, female sex, and obesity are considered to be risk factors for gallstone disease. The role of type 2 diabetes (T2D) in gallstone formation is still uncertain, and data in Indians is limited.

OBJECTIVES

This is a case-control study to determine the prevalence of gallstones (GS) in patients with T2D, risk factors, and the relative risk compared with subjects without diabetes, selected from the general population.

METHODS

Among 450 cases with T2D of a ≥2-year duration, 377 (88.8 %) participated. Diagnosis of GS was made at ultrasonography and history of cholecystectomy for GS. Controls were selected from the general population and diabetes excluded by oral glucose tolerance test. Cases and controls were matched for age, gender, and body mass index (BMI).

RESULTS

Gallstones were seen in 67 (17.7 %) cases compared to 40 (5.8 %) in controls (p = 0.001). Prevalence increased with increasing age with peak in the sixth decade (23.4 % in cases and 4.4 % in controls (p = 0.001) and was higher in women (27.9 %) in cases and (7.8 %) in controls, (p = 0.001). In univariate analysis, risk factors for GS included age, female sex, BMI, multiparity, family history of GS, and high triglycerides and cholesterol with low high-density lipoprotein cholesterol. In multivariate analysis, age, (relative risk [RR] 1.54, confidence interval [CI] 1.1-2.1), female sex (RR 1.6, CI 1.0-1.9), and BMI (RR 1.5, CI 1.3-2.5) were the independent risk factors in gallstone formation.

CONCLUSION

Patients with T2D had higher probability of having GS compared to the general population. Increasing age, female sex, and higher BMI were independently associated with gallstone disease.

Quantitative analysis of gallstones in Libyan patients

Gallstone disease is one of the major surgical problems in the Libyan population; it is probably related to diet, especially excessive consumption of meat. The study was conducted to determine the composition of gallstones and their possible etiology in a Libyan population. The chemical composition of gallstones from 41 patients (six males and 35 females) was analyzed. The stones were classified into cholesterol, pigment, and mixed stones (MS). Cholesterol stones (CS) showed a significantly higher cholesterol content than pigment stones (PS) (p=0.0085) though not significantly higher than MS. Their phospholipid content and inorganic phosphates were higher than in the other types of stones and oxalate content was significantly elevated in comparison with MS (p=0.0471). In MS, the cholesterol, bile acids, and bilirubin were intermediate between cholesterol and PS, whereas triglycerides were significantly more than PS (p=0.0004). Bilirubin (0.0001) and bile acids (p=0.0009) were significantly higher than CS (p=0.0001). However, they contained the lowest amounts of sodium, potassium, magnesium, and oxalate. In PS, bilirubin (p=0.0001) was significantly higher than both groups. Bile acid content was significantly higher than CS (p=0.0001) but not significantly more than MS. They showed the highest values of calcium, sodium, potassium, magnesium, and chlorides compared to the other types of stones. High levels of cholesterol in stones and dyslipidemia associated with mixed as well as cholesterol gallstones suggest an etiological association and efforts to reduce dietary fat among the Libyan population may lead to decreased cholesterol and mixed gallstones.
