Abstract

Objective: The aim of this study was to investigate the role of vitamin D deficiency in DMT1 pathogenesis by examining the effects of vitamin D levels on immune modulatory cytokines in patients with DMT1. Methods: Thirty adults with DMT1 from the endocrine clinic and 30 healthy controls were included in the study. Measurements for 25-hydroxyvitamin D (25OHD), soluble interleukin-2 receptor (sIL-2R), interleukin-6 (IL-6), and tumor necrosis factor-&#945; (TNF-&#945;) levels were obtained from serum samples from each study participant. Measurements were compared between the control group and the patient group. Correlations between 25OHD levels and the levels of sIL-2R, IL-6, and TNF-&#945; cytokines were investigated in patients with DMT1. Results: The mean 25OHD value for the DMT1 patients was significantly lower than for the control group (14.9±9.8 ng/ml versus 24.8±9.4 ng/ml, respectively; p<0.01). The mean sIL-2R and TNF-&#945; scores for patients with DMT1 were significantly higher than for the control group (707.3 ± 265 U/mL versus 403.1 ± 128 U/mL, respectively; p<0.01; and 10.2±3.0 pg/mL versus 3.8 ± 1.6 pg/mL, respectively; p<0.01). There was no significant difference between the mean IL-6 scores of the DMT1 patients and the controls (3.7±1.5 pg/mL versus 4.6±1.3 pg/mL, respectively; p=0,202). Negative correlations with varying levels of significance were observed between 25OHD and sIL-2R, IL-6, and TNF-&#945; cytokine levels in patients with DMT1. Conclusion: Vitamin D deficiency in DMT1 patients may contribute to disease pathogenesis by increasing sIL-2R, IL-6, and TNF-&#945; cytokines.

Özet

Amaç: Bu çalışmanın amacı tip 1 diyabetes mellitus (DMT1) hastalarında D vitamini düzeyinin immun düzenleyici sitokinlere etkilerini araştırarak vitamin D eksikliğinin DMT1’i nasıl oluşturduğunu araştırmaktır. Yöntemler: Çalışmaya endokrin kliniğine gelen toplam 30 erişkin DMT1’li ve 30 sağlıklı kontrol grubu dâhil edildi. DMT1 hastalarının ve kontrol grubunun serumlarında 25-hidroksivitamin D (25OHD), solubl interlökin-2 reseptör (sIL-2R) , interlökin-6 (IL-6), tümör nekrozis faktör alfa-α (TNF-α) düzeyleri ölçüldü. DMT1 hastalarda bulunan değerler ile kontrol grubu değerleri karşılaştırıldı. Yine DMT1 hastalarında 25OHD düzeyi ile sIL-2R,IL-6, TNF-α sitokinlerin düzeyleri arasında korelasyon olup olmadığı araştırıldı. Bulgular: DMT1 hastalarındaki ortalama 25OHD düzeyi kontrol grubundan anlamlı olarak daha düşüktü (sırası ile 14,9 ± 9,8 ng/ml, 24,8 ± 9,4 ng/ml, p<0,01). DMT1 hastalarındaki ortalama sIL-2R, TNF-α değerleri kontrol grubundan anlamlı olarak daha yüksekti. (sırası ile 707,3 ± 265 U/mL, 403,1 ± 128 U/mL, p<0.01) ve (10,2 ± 3,0 pg/ mL, 3,8 ± 1,6 pg/mL, p<0,01). DMT1 hastalarındaki ortalama IL-6 değerinin kontrol grubundan anlamlı farkı yoktu (3,7± 1,5 pg/mL karşı 4,6 ± 1,3 pg/mL, p=0,202). DMT1 hastalarındaki 25OHD değeri ile sIL-2R, IL-6, TNF-α sitokinlerin değerleri arasında değişik derecelerde negatif korelasyon bulundu. Sonuç: Bulunan negatif korelasyon DMT1 hastalarındaki D vitamini eksikliğinin, sIL-2R, IL-6, TNF-α sitokinleri arttırarak hastalığın patogenezinde etkili olabileceğini göstermektedir.
