Bone mineral density in short bowel syndrome: correlation with BMI and serum vitamins C, E and K

Abstract

Objective: Bone loss has been established as a major extra-intestinal complication of short bowel syndrome (SBS). The purpose of this study was to correlate bone mineral density (BMD) with body mass index (BMI), serum vitamin and mineral levels in patients with SBS. Material and methods: The study was conducted on 13 patients (8 male and 5 female, 54.7 ± 11.4 years) with SBS (residual small bowel length of 10 to 100 cm). We determined the food ingestion, anthropometry, serum levels of vitamins C, A, D, E and K, as well as serum and urinary levels of phosphorus and calcium. BMD was measured by dual-energy x-ray absorptiometry (DXA). Results: Osteopenia and osteoporosis was diagnosed in all but one SBS patient. Serum levels of vitamin D were low in all volunteers. Sixty-one percent of patients had vitamin E deficiency; hypovitaminosis A and C occurred in one subject. BMI and C, E and K vitamin serum levels correlated with T-score of BMD. Conclusions: Osteopenia and osteoporosis were common in SBS patients. There was a correlation between BMD and the serum levels of vitamins C, E and K, an indicative that such vitamins may influence bone health. Arch Endocrinol Metab. 2015;59(3):252-8

High Prevalence of Suboptimal Vitamin D Status and Bone Loss in Adult Short Bowel Syndrome Even After Weaning Off Parenteral Nutrition

“…Interestingly, in our study cohort, there was no significant difference in serum concentrations of calcium and phosphate between patients with normal and low BMD. A previous study confirmed that there was no statistically significantly difference between low BMD and decreased VtD concentration, while BMI and serum levels of calcium and PTH were significantly different, 7 , 22 which was different from our observations. In addition, no other demographic characteristics or clinical examinations were associated with bone loss.…”

Short bowel syndrome: influence of nutritional therapy and incretin GLP1 on bone marrow adipose tissue

“…In a previous study, Fan and colleagues (2016) found that, among 60 SBS patients, only two had a normal BMD (3.3%), while 96.7% had low bone mass—osteopenia (68.3%) and osteoporosis (28.4%) . Other studies confirm the high prevalence of osteopenia and osteoporosis in SBS patients …”

Management and Complications of Short Bowel Syndrome: an Updated Review

“…Bone disease occurs in up to 84 % of SBS patients on PN [84]. Bone mineral density (BMD) decline has been seen in association with reductions of serum vitamin C, E, and K concentrations [85]. Vitamin D concentrations are uniformly low in SBS patients, though its link to MBD in SBS patients is not as robust as found with celiac disease or primary biliary cirrhosis [86].…”
