Parathormone, 1,25 dihydroxyvitamin D and prostaglandin E2 correlation in children with idiopathic hypercalciuria.
As urinary prostaglandin excretion might be involved in idiopathic hypercalciuria, we studied the excretion of prostaglandin E2 and calcium together with serum prostaglandin E2, parathormone and 1,25 dihydroxyvitamin D in 20 patients and 11 controls Idiopathic hypercalciuric patients showed increased levels of urinary prostaglandin E2-like activity, which is correlated with calcium excretion. Although no change was observed in serum parathormone level in control and hypercalciuric patients, there was a positive correlation between serum 1,25 dihydroxyvitamin D and prostaglandin E2-like activity. These findings suggest that prostaglandin E2 could play a role in the hypercalciuria syndrome, possibly by increasing 1,25 dihydroxyvitamin D synthesis.
