BackgroundCardiovascular autonomic neuropathy (CAN) is associated with diabetes mellitus, increasing morbidity and mortality. Some cross-sectional studies associated CAN with low 25-hydroxyvitamin D levels. The aim of our study was to evaluate the effect of high-dose vitamin D (VD) supplementation on CAN in Type 1 Diabetes Mellitus (T1DM) patients.MethodsWe performed a prospective study with 23 patients diagnosed with T1DM and CAN. Subjects with VD levels <30 ng/ml received 10,000 IU/day; the ones with VD levels between 30–60 ng/ml were given 4,000 IU/day for 12 weeks.ResultsThere was an improvement in CAN parameters related to resting heart rate variability, such as time domain parameters [Maximum RR interval (0.77 ± 0.11 vs 0.94 ± 0.51 s, p <0.05), Mean length of regular RR intervals (0.71 ± 0.10 vs 0.76 ± 0.09 s, p <0.05) and Standard deviation of all NN intervals (0.02 ± 0.01 vs 0.03 ± 0.02 s; p <0.01)] and frequency domain parameters [Low Frequency (1.9 ± 0.5 vs 2.5 ± 0.9 s, p < 0.001), Total Power (2.5 ± 0.4 vs 2.8 ± 0.6 s, p <0.05)]. In addition, there was a correlation between absolute VD level variation and posttreatment High Frequency (%), as well as among percent variation in VD level and end-of-study Low Frequency/High Frequency ratio (r=0.6, p<0.01; r= -0.5, p<0.05, respectively).ConclusionOur pilot study is the first to suggest a strong association between high-dose vitamin D supplementation and improved cardiovascular autonomic neuropathy in T1DM patients. It occurred without any variation in HbA1C, blood pressure levels, lipids, and insulin dose.Clinical Trial Registrationhttp://www.isrctn.com/ISRCTN32601947, identifier ISRCTN32601947.

Over the last decades a considerable amount of data has accumulated to indicate that metabolic and endocrine alterations of diabetes affect bone quantity and quality. These skeletal changes may increase the risk of bone fracture. There is strong evidence that in type 1 diabetes the decreased bone mass, lack of insulin and insulin-like growth factor-1, dysregulation of adipokines, and increased levels of proinflammatory cytokines are in the background of fragility fractures. In type 2 diabetes hyperinsulinemia, insulin resistance and increased body weight may result in an increase of bone mass; however, accumulation of advanced glycation end products within the bone collagen driven by glucotoxicity may increase the cortical porosity. There is a higher incidence of falls resulting from diabetes-related co-morbidities such as diabetic retinopathy, peripheral neuropathy, hypoglycemic episodes and sometimes from the medications. Vitamin D deficiency has special impact on glucose metabolism and the prevalence of diabetes. Vitamin D supplementation in childhood can decrease incidence of type 1 diabetes by 80%. The effect of thiazolidinediones, glucagon-like peptide-1 agonists and metformin, agents for treatment of diabetes open a new connection between bone, carbohydrate and fat metabolism. Orv.
