Ascorbic Acid Deficiency↗

Ascorbic acid status in uremics.

Plasma levels of ascorbic acid (AA) and dehydroascorbic acid (DHA) were estimated in 27 patients of end stage renal failure (ESRF) on standard conservative therapy (group A) and 9 patients of ESRF on maintenance haemodialysis (MHD; group B). Fourteen healthy subjects matched for age and sex served as control (group C). The dietary intake of vitamin C was significantly decreased in group A than in group B compared to control. Similarly, plasma AA was significantly lowered to 0.801 +/- 0.283 mg per cent in group A compared to 1.421 +/- 0.47 mg per cent in control. While it was just lowered to 1.058 +/- 0.272 mg per cent in group B. Although plasma level of DHA was raised to 0.243 +/- 0.486 mg per cent and 0.166 +/- 0.54 mg per cent in groups A and B respectively, the increase was not statistically significant. In our present study, the DHA/AA ratio was found to be inversely proportional to the plasma AA. Further, this ratio has been claimed to be a better indicator of overall reducing atmosphere (i.e., profile of vitamin C) of the body.
