Tip 2 diyabetli hastalarda d vitamini eksikliği prevalansı ve crp, fibrinojen, glisemik kontrol ve insülin direnci ile ilişkisi

Amaç: Tip 2 diyabetli hastalarda serum 25-hidroksivitamin D eksikliği prevalansmı ve D vitamini eksikliğinin hassas CRP, fibrinojen, lipid ve lipoprotein düzeyleri, glisemik kontrol ve insülin direncine etkisini incelemek amaçlandı.Gereç ve Yöntemler: Toplam 132 hasta (79 kadın, 53 erkek) çalışmaya alındı.Bulgular: Hastaların %37,9'unda (kadınlarda %53,2, erkeklerde %15,1) D vitamini eksikliği saptandı. Obez ve kapalı giyim tarzı olan kadın hastaların %71,9'unda D vitamini eksikliği saptandı. D vitamini eksikliği olan kadın hastaların olmayanlara göre VKİ ve PTH düzeyleri yüksek; apolipoprotein A ve HDL kolesterol düzeyleri düşük bulundu. CRP, fibrinojen, kan şekeri, HbAlc düzeyleri ve HOMA-IR farklı değildi. D vitamini eksikliği olan erkek hastalarda olmayanlara göre bakılan parametreler açısından farklılık saptanmadı. Tüm grupta, D vitamini ile VKİ, HOMA-IR, PTTI ve ALP ile negatif; kreatinin ile pozitif ilişki saptandı.Sonuç: Çalışmamızda tip 2 diyabetli hastalarda D vitamini eksikliği pre-valansının yüksek olduğu, bu oranın obez ve kapalı giyim tarzı olan kadınlarda daha belirgin olduğu görüldü. D vitamini düzeyi insülin direnci ile ilişkili bulunurken; D vitamini eksikliğinin CRP, fibrinojen ve glisemik kontrol üzerine bir etkisi saptanmadı.

The prevalence of vitamin d deficiency and its relationship with crp, fibrinogen, glycemic control and insulin resistance in patients with typer diabetes

Aim: We aimed to investigate the prevalence of 25-hydroxyvitamin D deficiency and the effect of vitamin D deficiency on sensitive C-reactive protein (CRP), fibrinogen, lipid, lipoprotein levels, glycemic control and insulin resistance in patients with type 2 diabetes mellitus (DM). Methods: A total of 132 patients (79 women and 53 men) were enrolled the study.Results: Vitamin D deficiency was found in 37.9% of the patients (53.2% in women and 15.1% in men). The frequency of vitamin D deficiency in obese female patients wearing covered dress was 71.9%. Female patients who are vitamin D deficient had increased BMI, PTH and decreased apolipoprotein A and HDL cholesterol levels compared to vitamin D sufficient female patients. But CRP, fibrinogen, blood glucose, HbAlc levels and HOMA-IR were not different in these two groups. The measured parameters were comparable between male patients with and without, vitamin D deficiency. In whole group, vitamin D correlated negatively with BMI, HOMA-IR, PTH, ALP and positively with creatinine.Conclusion: In our study, we observed increased prevalence of vitamin D deficiency in patients with type 2 DM, especially in obese female patients wearing covered dress. While there was an association between vitamin D and insulin resistance, there was no effect of vitamin D deficiency on CRP, fibrinogen and glycemic control.
