Abstract
Introduction: Chronic kidney disease (CKD) causes decreased activity of the enzyme 1-alpha-hydroxylase and calcitriol deficiency with mineral and bone metabolism disorders or secondary hyperparathyroidism. Anticipation of the occurrence of these complications implies the systematic supplementation of all hemodialysis patients, with monitoring of biological parameters. It is in this context that this study was carried out, the general objective of which was to establish the profile of vitamin D concentration in hemodialysis and Ivorian public sector supplemented patients in Abidjan.
Patients and Methods: In a cross-sectional study conducted from September to December 2022, we included 89 patients with end-stage CKD treated with hemodialysis at the CNPTIR in Cocody. The collection of epidemio-clinical data was done on the basis of a questionnaire on the one hand and the patients' medical records on the other. The vitamin D concentration was determined by the ELFA immunoassay method on mini Vidas (BIOMERIEUX).
Results: The mean age of the patients was 45 ± 13 and 65.17% of them were men. 55.06% of the patients had been treated with dialysis for at least 5 years. 48.31% of the patients had regular supplementation treatment. Of the two types of vitamin D supplementation, 94.38% of the study population was supplemented with cholecalciferol compared to 18% for alfacalcidol with 12% of patients included, using both types. From a biological point of view, it appears that the average concentration of vitamin D in the patients was 26.9 ng/mL, and only 16% have a concentration of less than 20 mg/mL, corresponding to an deficiency vitamin D status.
Conclusion: At the end of this cross-sectional study, it emerged that the average in adult hemodialysis subjects followed at the CNPTIR in Cocody had an insufficient vitamin D status. And 37% of the study population with normal vitamin D status. However, these results could be improved by better accessibility to the products, and regular compliance with supplementation.
