A cross sectional analysis of 41 patients on continuous ambulatory
peritoneal dialysis (CAPD) for six to 54 months (mean, 21.7) showed that 58.5%
and 19.5% had low levels of 1,25-(OH)2 vitamin D and 25-OH vitamin D
respectively. C-terminal and N- terminal parathyroid hormone (PTH) levels were
elevated in 85 and 75%, respectively. N-terminal PTH correlated (r -0.31, p
< 0.05) with serum inorganic phosphorus, but not with vitamin D levels.
Triglyceride and cholesterol concentrations were elevated in 76% and 19%; HDL
cholesterol was low in 37%. Except for PTH levels, none of the other above
measurements correlated with time on CAPD. The findings suggest that most CAPD
patients have low 1,25(OH)2 vitamin D and elevated PTH and triglyceride serum
concentrations. More study should be made concerning the clinical significance
of and proper therapeutic interventions in these circumstances.
KEY WORDS: Vitamin D; Cholesterol; Triglycerides; Parathyroid Hormone.
