Serum 25(OH) D vitamini düzeyinin hemogram parametreleri üzerine etkisi

Amaç: D vitamini pleitropik hormon özellikleri olan yağda çözünen bir vitamindir. Genel anlamda rikets ile beraber anılır ancak yapılan araştırmalar D vitamininin kemik dışı dokularda da etkin olduğunu göstermektedir. Biz de bu çalışmada serum D vitamini düzeyinin hemogram parametrelerine etkisi olup olmadığını araştırmayı amaçladık. Yöntemler: Bu retrospektif çalışma, 243 kadın 59 erkek toplam 302 hastanın verileri değerlendirilerek gerçekleş- tirildi. Hastaların D vitamini düzeyi ve hemogram [eritrosit sayısı (RBC), hemoglobin (Hb), beyaz küre sayısı (WBC), trombosit sayısı (PLT), ortalama trombosit volümü (MPV) ve eritrosit dağılım genişliği (RDW)] parametreleri elde edildi. Hastalar D vitamini düzeylerine göre 4 gruba ayrıldı: Grup 1: < 10 ng/mL; Grup 2: 10-19 ng/mL; Grup 3: 20-29 ng/mL ve Grup 4: 30-60 ng/mL. Bulgular: Gruplar arası RBC, Hb, WBC, PLT, MPV ve RDW değerleri arasında anlamlı bir farklılık saptanmadı (p>0.05). Ayrıca, D vitamini ile hemogram parametreleri arasında herhangi bir korelasyon tespit edilmedi. Sonuçlar: Literatüre bakıldığında D vitamini ile WBC, RBC ve PLT arasında ilişki olduğunu gösteren çok sayıda yayın bulunmaktadır. Ancak, bizim çalışmamızda literatürün aksine D vitamini ile hemogram parametreleri arasında herhangi bir ilişki tespit edilemedi. Bu sonuçlar D vitamininin hematopoietik sistem üzerindeki etkilerinin deneysel ve klinik olarak daha iyi araştırılması gerektiği fikrini vermektedir.

The effect of serum 25(OH) vitamin D on hemogram parameters

Objective: Vitamin D that has pleiotropic hormone characteristics is a fat soluble vitamin. In general, vitamin D is known to be associated with rickets, but the studies show that vitamin D also acts on tissues and cells other than bone itself. In this study, we aimed to investigate if vitamin D has any effects on hemogram parameters or not. Methods: This retrospective study was done with the data obtained from 243 female and 59, totally 302 patients. Vitamin D level and hemogram parameters [(red blood cell (RBC), hemoglobin (Hb), white blood cell (WBC), platelet (PLT), mean platelet volume (MPV), and red cell distribution width (RDW)] of patients were obtained. Patients were divided into 4 groups according to their levels of vitamin D: Group 1: < 10 ng/mL; Group 2: 10-19 ng/mL; Group 3: 20-29 ng/mL, and Group 4: 30-60 ng/mL. Results: There were no significant differences in RBC, Hb, WBC, PLT, MPV, and RDW between the groups (p>0.05). Also, there was no correlation between the hemogram parameters and vitamin D. Conclusion: According to the literature, there are a lot of studies that show the relationship between vitamin D and WBC, RBC, and PLT. However, contrary to the previous studies, we were unable to find any significant relationship between vitamin D and hemogram parameters. These results serve the idea that the effects of vitamin D on the hematopoietic system should be further investigated experimentally and clinically.
