Abstract

This study compared the 25-hyrdoxyvitamin (OH) D and bone mineral density (BMD) values of patients with and without cholecystectomy. Although 25(OH) D levels were significantly lower in the cholecystectomy group (12.1 ± 6.2 vs. 15.6 ± 6.6 ng/mL), no significant difference was observed between the groups in terms of BMD measurements.

INTRODUCTION:

Although 25 (OH) D levels were studied and found to be lower in patients with cholecystectomy, the data is scarce as regards the BMD. Therefore, the aim of this study was to compare the 25(OH) D and BMD values of patients with cholecystectomy and without cholecystectomy.

METHODS:

This study was a single-center and case-control trial. The cholecystectomy group comprised the patients with a history of cholecystectomy. In addition, a healthy control group without history of cholecystectomy was defined. All patients were selected consecutively from the patients who admitted to the outpatient clinics of physical and rehabilitation medicine or internal medicine between the June 2016 and August 2016. The patients were ambulatory and did not receive any osteoporosis treatment before. Chemiluminescence microparticle immunoassay method was used for 25(OH) D measurements. Dual-energy X-ray absorptiometry was used for the BMD evaluations.

RESULTS:

There were 46 patients in the cholecystectomy group with a mean age of 58.6 ± 14.1 years and 64 patients in the control group with a mean age of 59.2 ± 13.3 years. Although 25(OH) D levels were significantly lower in the cholecystectomy group (12.1 ± 6.2 vs. 15.6 ± 6.6 ng/mL) (p =  0.010), no significant difference was observed between the groups in terms of BMD measurements (p > 0.05). While there was a weak positive correlation between the BMI and BMD measurements (all p < 0.05), linear regression analyses showed that the models were not valid (femoral neck R = 0.092; femur total R = 0.170; and lumbar total R = 0.199). No significant difference was observed between the BMD measurements and time after cholecystectomy in the cholecystectomy group (p > 0.05).

CONCLUSION:

In the light of our results, cholecystectomy patients seem to have lower level of 25(OH) D levels in comparison with healthy subjects, but both groups have similar BMD values. Further studies in cohort designs taking into account the bone formation and resorption markers are awaited.
