Abstract

Hypocalciuric
familial hypercalcemia is a benign disease caused by mutations in the calcium-sensitive
receptors, with modareta hypercalcemia and of calcium excretion in the urine leading
to less. Six patients was evaluated in our internal medicine policlinic with clinic
and biochemistyr parameters between 2010 January and 2015 June. Our cases were six
patients including four vomen between 21 and 86 old. We evaluated in our policinic
five cases childs and one cases parents. The results of evaluation of the patients
were thought to be familial hypocalciüric hypercalcemia because of moderate hypercalcemia,
borderline high parathormone levels and marked impairment of urinary calcium excretion.
The diagnosis was confirme exclusion of other causes of hypercalcemia and the childrens
of five patients and mother of one patients detected in calcium metabolism in
the laboratory findings are similar to.

Familyal hipokalsiürik hiperkalsemili olgularımız

Abstract


Ailesel hipokalsiürik hiperkalsemi,
ılımlı hiperkalsemi, idrarda kalsiyum atılımının az olması ile giden ve
kalsiyum duyarlı reseptörlerde mutasyonlardan kaynaklanan benign bir
hastalıktır. 2010 Ocak ile 2015 Haziran ayları arasında İç hastalıkları
polikliniğimize başvuran altı hasta klinik ve biyokimyasal paremetrelerle
değerlendirilmiştir. Olgularımız, 21 ile 86 yaş arasında, dördü kadın olmak
üzere toplam altı hasta idi. Beş olgumuzun çocukları ve bir olgumuzun
ebeveynleri poliklinik ortamında değerlendirildi. Olguların değerlendirmesinde
ılımlı hiperkalsemi, sınırda yüksek parathormon düzeyleri ve idrarla günlük
kalsiyum atılımının belirgin düşüklüğü nedeniyle ailesel hipokalsiürik hiperkalsemi
olabileceği düşünüldü. Beş erişkin hastanın çocuklarında ve bir genç hastamızın
da annesinde kalsiyum metabolizmasında benzer laboratuvar bulguları saptanması
ve hiperkalsemi yapan diğer nedenlerin dışlanması üzerine tanı doğrulandı.
