| Popis: | Local reference values are important for ihe correct approach lo the diagnosis and management of idiopathichypercalciuria. Ninety seven healthy children were evaluated lo determine daily normal urine calcium excretion. A meanvalue of 0.1 3 (M « 0.08), was obtained for the calcium/aeatinine urinary index. We also studied ihe relationshipbetween urinary calcium and sodium excretion (n = 47). A positive, stalislically significant relation could be stablished |p< 0.01 ]. To examine the relationship between calcium-creatinine urinary index and calcium excretion in a 24 hour urinesample, 44 children whilh hypercalciuria were evaluated. A strong correlation (r = 0.89} was obtained showing theclose association among results from both methods, p < 0.001. Two lest were evaluated In seventy eighl patients withhypercalciuria in ofder to identify renal and absortive hypercalciuria subtypes. A one week calcium restriction testshowed less non diagnosis results (0/45 cases) than the classic calcium loadig tesl (6/33 cases), leading to belterclassification of these patients.[Key words: calcium metabolism disorders, idiopathic hypercalcluria, urine calcium/creatinine index.) |
