AIM To evaluate the prevalence of vitamin D deficiency and its relation to diabetes and kidney disease in Veterans residing in the North East United States(VISN 2). METHODS In this retrospective study, we used data from the computerized patient record system at Stratton Veterans Administration Medical Center at Albany, NY(VHA) for those patients who had 25-hydroxyvitamin D levels and 1,25(OH) vitamin D levels measured between 2007 and 2010. We collected demographic information including age, sex, body mass index and race; clinical data including diabetes, hypertension and CAD; and laboratory data including calcium, creatinine and parathyroid hormone(PTH)(intact). Vitamin D deficiency is defined as a serum 25-hydroxyvitamin D level of less than 20 ng/mL(50 nmol/L), and insufficiency is defined as a serum 25-hydroxyvitamin D level of 20 to 30 ng/mL(50 to 75 nmol/L). RESULTS Data was available for approximately 68000 subjects. We identified 64144 subjects for analysis after exclusion of duplicates. Among them, 27098 had diabetes. Themean age of subjects with diabetes was 68 ± 11 with a mean body mass index(BMI) of 32 ± 7 and duration of diabetes of 5.6 ± 3.2 years. The mean 25(OH) vitamin D level among subjects with diabetes was 27 ± 11.6. There was no significant difference in 25(OH) vitamin D levels between subjects with diabetes and glomerular filtration rate(e-GFR) < 60 compared to those with e-GFR ≥ 60. As expected, subjects with e-GFR < 60 had significantly lower 1,25(OH) vitamin D levels and significantly elevated PTH-intact. Of the 64144 subjects, 580 had end-stage renal disease. Of those, 407 had diabetes and 173 did not. Vitamin D levels in both groups were in the insufficiency range and there was no significant difference irrespective of presence or absence of diabetes. Subjects with vitamin D levels less than 20 ng/mL had a higher BMI and elevated PTH, and higher HbA 1C levels compared to those with vitamin D levels more than 20 ng/mL. CONCLUSION We conclude that we need to keep a close eye on vitamin D levels in subjects with mild chronic kidney disease as well as those with moderate control of diabetes.
