Abstract

Type 1 Diabetes Mellitus (T1DM) is the consequence of autoimmune destruction process of β cells which associated with Th17 activity and low 25(OH)D level. This study was aimed to investigate the effect of vitamin D3 supplementation toward 25(OH)D level, Th17 activity (IL-17) and glycemic control (HbA1c) in pediatric T1DM. This study was designed as randomized clinical trials (RCT), double-blind, pre and post-test controlled study. Subject was children with T1DM who were divided into two groups: K1: subjects were treated with insulin 0.5–2 IU/day + vitamin D3 2000 IU/day for 3 months, K2: subjects were treated with insulin 0.5–2 IU/day + placebo for 3 months. Levels of 25(OH)D, IL-17 and HbA1c were evaluated after 3 months treatment using ELISA. After 3 months treatment, results showed that 25(OH)D level was significantly higher in K1 compared with K2 (p = 0.00), IL-17 level was significantly lower K1 compared with K2 (p= 0.022). Surprisingly, HbA1c level in K1 was not significantly different with K2 (p = 0.93). Furthermore, in vitamin D-treated group, 25(OH)D level was elevated significantly after 3 months treatment with vitamin D (p = 0.00), IL-17 level was reduced significantly after 3 months treatment with vitamin D (p= 0.001)  and HbA1c level was reduced insignificantly after 3 months treatment with vitamin D (p= 0.76). Correlation study showed that there was no correlation between 25(OH)D level with IL-17 level (p= 0.160, r= -0.284) and 25(OH)D with HbA1c (p= 0.62, r= -0.10). This study can be conclude that vitamin D3 supplementation may elevate the 25(OH)D and reduce IL-17 level but did not change HbA1c level in pediatric T1DM.

Abstract

Type 1 Diabetes Mellitus (T1DM) has become a health problem in many countries. T1DM is the consequence of autoimmune destruction process of β cells. There was relationship between vitamin D deficiency with T1DM. The destruction process was caused by an imbalance of pro-inflammatory and anti-inflammatory cytokines. One of the pro-inflammatory cytokines is IL-2. C-peptide examination to see the function of beta cells due to destruction of pancreatic beta cell. Administration of vitamin D3 supplementation still cause controversy and give varying results. This randomized clinical trial was conducted to determine the levels of 25(OH)D3, IL-2, and C-peptide in people with T1DM who received vitamin D3 supplementation. The subjects were 26 children with T1DM, divided into K1 group (received vitamin D3 supplementation) and K2 group (received placebo). The results showed higher levels of 25(OH)D3 in the K1 group and statistically found a significant difference (p = 0.00). Higher levels of IL-2 and lower C-peptide were obtained in the K1 group and no statistically significant differences were found (p = 0.76 and p= 0.26). The insignificant relationship and the negative correlation were found between 25(OH)D3 and IL-2 (p = 0.71; r = - 0.12), 25(OH)D3 and C-peptide (p = 0.59; r = -0.16), also levels of IL-2 and C-peptide (p = 0.13; r = -0.44) in children with type 1 diabetes who received vitamin D3 supplementation. From this study can be concluded that administration vitamin D3 supplementation in patients with T1DM can increase levels 25(OH)D3 significantly. This increase has not significantly lowered levels of IL-2 and increased levels of C-peptide. However, there was an absolute decrease in the rate of slower C-peptide in the supplemented group than in the placebo group.
