Description
Type 1 diabetes mellitus children who had been treated with long-acting insulin (glargine) and fast-acting insulin (aspart) based on the Basal Bolus Insulin Protocol (BBIP) in the last five years, with at least 6 months after the onset of their diabetes will be selected as the sample and their C-peptide levels will be tested, initially. The, those children who have basal C-peptide levels> 0.2 nmol/l will be tested for vitamin D (VD) levels. Those with 25(OH) D levels lower than 30 (ng/ml), which means decreased level of VD, will be included in the study. If their VD level be between 20 and 30 (ng/ml), indicating VD insufficiency, they will receive D-VITIN 50000U PEARL per week for up to 6 weeks, and if their VD level be lower than 20 (ng/ml), which indicates VD deficiency (15), they will receive D-VITIN 50000U PEARL for up to 8 weeks. Then, the children's VD levels will be re-tested and if it will be shown to be low, the weekly treatment with the same previous level will be continued until they have normal VD levels (more than 30 (ng/ml). If they will fail to reach a normal level of this vitamin after another six-to-eight-week period of D-VITIN PEARL, the patients will be excluded from the study. After correcting the patients' levels of VD, a single dose of VD will be administered for each month until the end of the study (9 months) and finally, their C-peptide, 25OH (D), and HbA1C levels will be checked again and their C-peptide, 25OH (D), HbA1C and TDD will be compared at the beginning and end of the study. Insulin Lantus (Glargine) was manufactured by SANOFI-Aventis Germany and Insulin Novorapid (aspart) was manufactured by NOVO NORDISK A/S, a Danish multinational pharmaceutical company. D-VITIN 50000U PEARL was manufactured by Zahravi Pharmaceutical Company in Iran. To check the above, we needed 3 cc of blood clots. C-peptide will be measured by the ELISA method using a Diasorin kit produced in Italy, VD will be measured by the ELISA method using the Ids kit made in England and HbA1C will be measured by an enzymatic method using a Pishtazteb kit made in Iran, and the results will be recorded.
