Abstract Roux-en-y Gastric Bypass is a very common surgical procedure in managing morbid obesity. Approximately 303,890 roux-en-y surgeries were performed in the United States in between the years of 2012 to 2017, and the number is steadily increasing as more Americans are diagnosed with obesity.i This featured case report describes a 52-year-old female presenting with complications seven years following Roux-en-y gastric bypass. Four years post-operatively, she presented to the ER with a pelvis fracture. It was incidentally found that she had osteoporosis with a t-score of -2.9. It was also found that her bone mineral density (BMD) for women for her age was low with a z-score of -3.5 and her 10-year probability of getting fractures was high with a Fracture Risk Assessment Tool (FRAX) score of 6.2%. Seven years following Roux-en-y gastric bypass, she presented to our primary care office with Vitamin B12 deficiency and secondary hyperparathyroidism due to Vitamin D deficiency. We attempted to correct the deficiencies with high dose of Vitamin D, Vitamin B12, and calcium citrate. Eight months later, the B12 levels was normalized, but the secondary hyperparathyroidism and Vitamin D deficiency were not corrected. This case illustrates the complications that can occur following a Roux-en-y Gastric Bypass, importance of supplement compliance, and proper follow-up with Roux-en-y patients.

Abstract. We aim to assess the prevalence of vitamin D deficiency (VDD) in patients scheduled for bariatric surgery (BS), and to identify factors that might be associated with VDD. We conducted a cross-sectional observational study involving all consecutive patients scheduled for BS from 2017 to 2019. The exclusion criteria were missing data for vitamin D levels, intake of vitamin D supplements in the 3 months prior to serum vitamin D determination, and renal insufficiency. A total of 206 patients (mean age and body mass index [BMI] of 34.9 ± 10.7 years, and 44.3 ± 6.99 kg/m2, respectively) met the inclusion criteria and were enrolled for data analysis. VDD (<19.9 ng/mL), severe VDD (<10 ng/mL), and vitamin D insufficiency (20–29.9 ng/mL) were present in 68.8 %, 12.5 %, and 31.2 % of patients, respectively. A significant inverse correlation was found between vitamin D levels and initial BMI, parathyroid hormone, and homeostatic model assessment of insulin resistance (r = −0.280, p < 0.05; r = −0.407, p = 0.038; r = −0.445, p = 0.005), respectively. VDD was significantly more prevalent in patients with higher BMI [−0.413 ± 0.12, CI95 % (−0.659; −0.167), p = 0.006], whereas no significant association between hypertension [−1.005 ± 1.65, CI95 % (−4.338; 2.326), p = 0.001], and diabetes type 2 (T2D) [−0.44 ± 2.20, CI95 % (−4.876; 3.986), p = 0.841] was found. We observed significant association between female sex and levels of vitamin D [6.69 ± 2.31, CI95 % (2.06; 11.33), p = 0.006]. The present study shows that in patients scheduled for BS, VDD deficiency is common and was associated with higher BMI, and female sex.

Increased Risk

During the last two decades, the potential impact of vitamin D on the risk of cardiovascular disease (CVD) has been rigorously studied. Data regarding the effect of vitamin D on CVD risk are puzzling: observational data indicate an inverse nonlinear association between vitamin D status and CVD events, with the highest CVD risk at severe vitamin D deficiency; however, preclinical data and randomized controlled trials (RCTs) show several beneficial effects of vitamin D on the surrogate parameters of vascular and cardiac function. By contrast, Mendelian randomization studies and large RCTs in the general population and in patients with chronic kidney disease, a high-risk group for CVD events, largely report no significant beneficial effect of vitamin D treatment on CVD events. In patients with rickets and osteomalacia, cardiovascular complications are infrequently reported, except for an increased risk of heart failure. In conclusion, there is no strong evidence for beneficial vitamin D effects on CVD risk, either in the general population or in high-risk groups. Whether some subgroups such as individuals with severe vitamin D deficiency or a combination of low vitamin D status with specific gene variants and/or certain nutrition/lifestyle factors would benefit from vitamin D (metabolite) administration, remains to be studied.

Control Study

Objective: We aimed to find out the association of low serum vitamin D levels with the incidence of prostate cancer through a prospective case-control study. Material and methods: This study was carried out in the tertiary care hospital (India). All newly diagnosed patients of prostate cancer and age-matched controls were included. Serum vitamin D levels were measured in all of them. Vitamin D status (ng/mL) was classified as severe deficiency <10, moderate deficiency 10–<30, normal 30–100, and toxicity >100. Normality of the data was tested by the Kolmogorov–Smirnov test, statistical analysis was done with Statistical Package for the Social Sciences version 26.0, p-value of <0.05 was considered significant. Results: In our study, 320 cases and 320 controls were included. The mean vitamin D levels in cases and controls were 15.71 ± 6.5 (ng/mL) and 17.63 ± 4.54 (ng/mL), respectively, ( p-Value <0.01). Patients with severe vitamin D deficiency (73.58%) had a Gleason score ⩾8 on biopsy and 79.24% of them had a serum prostate specific antigen (PSA) level >20 ng/mL. Conclusion: We had concluded that there was no significant association between vitamin D deficiency and increased risk of prostate cancer, although patients with higher-grade prostate cancer and with higher PSA level had severe vitamin D deficiency. Level of evidence: Not applicable for this multicentre audit.
