Abstract
Background and Aims
25(OH)D3 levels are known to be lower in patients with chronic renal disease (CRD). Vitamin D supplementation has been shown to have beneficial effects on mortality in these patients. In our study, we have evaluated the pleiotropic effect of vitamin D on thrombocyte markers, which is known very little by most.
Method
The main thrombocyte function markers (MPV, PDW and PCT) were obtained in patients which underwent dialysis, renal transplantation and patients with grade 3-4 CRD before and after vitamin D supplementation. 40 healthy individuals were chosen as control group and 24 patients underwent renal transplantation, 25 patients underwent dialysis for at least 3 months, 32 patients were diagnosed as Grade 3-4 CRD. All of the patients above had 25(OH)D3 levels <20ng/mL (<50nmol/L). Thrombocyte markers were evaluated before and after vitamin D supplementation (which was given 50.000 IU orally once a week for 8 weeks).
Results
Statistically no significant difference were found between MPV values in- and across- group comparison before and after vitamin D supplementation. After the correlation analyses were reviewed, statistically significant negative correlation was found (r=-0,422 p<0.05) between ΔMPV and ΔVitamin D in renal transplantation group. Also statistically significant positive correlation was found between ΔPDW and ΔVitamin D. In the control group with healty participants, a statistically significant negative correlation was found (r=-0,493 p<0.05) between ΔVitamin D and ΔThrombocyte count. In the dialysis group a statistically significant negative correlation was found (r=-0,422 p<0.05) between ΔVitamin D and ΔMPV.
Conclusion
A significant correlation was found particularly between Vitamin D and MPV in dialysis and renal transplantation patients. In order to prevent cardiovascular events due to thrombosis caused by Vitamin D deficiency which increases MPV, it has been thought that Vitamin D supplementation and antiaggregant therapy might be beneficial.
