Abstract:
In order to study the correlation between the levels of vitamin B6, folic acid (vitamin B9)
and vitamin D with the clinical course of CKD, 153 patients aged 20 to 94 years were examined,
with an average age of 57.9±2.3 years. The analysis of the obtained data showed that the average
concentration of vitamin B6 and folic acid in all cases was within the lower limit of the standard
values. In all cases, a decrease in vitamin D was found, corresponding to both deficiency and
deficiency. Correlation analysis proved the average dependence of vitamin D on GFR.
