Abstract

Amaç : Renal hiperkalsiürili çocuklarda sessiz olarak seyreden, fazla önemsenmeyen osteoporoz sıklığını araştırmak amacıyla İTF Çocuk Nefroloji BD’de renal hiperkalsiüri tanısıyla takipli, 3-10 yaş arası 20 çocuk çalışmaya kabul edildi. Yöntemler: Kemik mineral yoğunlukları DEXA cihazı ile ölçüldü. Vakaların böbrek fonksiyon testleri, serum elektrolitleri, serum alkalen fosfataz, kalsiyum, fosfor, parathormon, osteokalsin, kalsitriol düzeyleri, idrar kalsiyum/ kreatinin, 24 saatlik idrar kalsiyum atılımları incelendi. Bulgular: Çocukların 5’i % 25 osteoporotik, 4’ü % 20 osteopenik bulundu. Kemik mineral yoğunlukları ile 24 saatlik idrar kalsiyum atılımları, spot idrar kalsiyum/kreatinin oranları arasında negatif yönde güçlü ilişki saptandı r= -0.587, p= 0.007 , r= -0.629, p= 0.03 . Sonuç: Sonuçlar şimdiye kadar yapılan benzer çalışmalarla karşılaştırıldı.Sonuçlarımız renal hiperkalsiürili hastalarda osteoporozun önemli bir sorun olduğunu göstermektedir.

The Prevalence of Osteoporosis in Renal Hypercalciuric Children

Abstract

Objective: To determine the prevalence of silent osteoporosis which is considered to be unimportant in renal hypercalciuric children, 20 children between 3-10 years of age who were followed by ITF Department of Pediatric Nephrology with the diagnosis of renal hypercalciuria included in the study. Methods: Bone mineral densities measured by DEXA scanner. Renal function tests; serum electrolit, alkaline phosphatase, calcium, phophorus, parathormone, calcitriol levels; urinary calcium to creatinin Ca/Cr ratios, daily urinary calcium excretions investigated. Results: Twenty-five percent of children were osteoporotic, and % 20 of them were osteopenic. Lumbar spine bone mineral density measurments were inversely correlated with urine Ca/Cr ratios r= -0.587, p=0.007 ; and daily urinary calcium levels r= -0.629, p=0.03 . Conclusion: Our results support the importance of osteoporosis in renal hypercalciuric children.
