Mean Platelet Volume and Vitamin D Deficiency

Abstract

86 ABS TRACT Materials and Methods:This was a retrospective study. The children followed-up at the pediatrics endocrinology polyclinic and diagnosed as nutritional rickets were included in this study. The patient group was created, and by screening the files of 478 case files, those compatible with the patient group for age and gender, were taken as the control group. Results: A total of 684 children and adolescents cases between the ages 0.1-18 years were included in the study. The cases were divided into 3 groups according to the vitamin D levels. Those with vitamin D levels of less than 15 ng/mL were classified as the vitamin D deficiency group, those between 15-20 ng/mL were classified as the insufficiency group, and those between 20-100 ng/mL were classified as the normal Vitamin D level group. There was no statistically significant difference between the groups in terms of age and gender. There was no significant difference observed between the groups in terms of the MPV levels. There was no statistically significant correlation determined in the correlation analysis between the vitamin D level and the MPV (p>0.05). In the multiple regression analysis, it was observed that vitamin D had no statistically significant effect on MPV. In the performed partial correlation analysis, when hemoglobin, hematocrit, calcium, phosphorus and parathyroid hormone were selected as controlling factors, again, there was no statistically significant correlation observed between the MPV and the vitamin D (r=-0.19, p>0.05). Conclusion:In the pathophysiology of the cardiac dysfunctions appearing as a result of vitamin D deficiency, we wished to emphasize that the hypothesis of the probable effect of vitamin D on MPV should be questioned in more detail.
