Maternal Vitamin D Eksikliği Ve Paratiroid Adenomuna Bağlı Geç Neonatal Hipokalsemi: Olgu Sunumu

Year 2007, Volume: 1 Issue: 2, 37 - 41, 01.04.2007

Abstract

Geç neonatal hipokalsemi; fosfat yükü fazla beslenmelerde, intestinal Ca malabsorbsiyonu,hipomagnezemi, hiperparatiroidili anne bebeği, maternal vitamin D eksikliği durumlarında görülebilmektedir. Burada annede vitamin D eksikliğine bağlı hiperparatiroidi ve paratiroid adenomu gelişen geç neonatal hipokalsemili bir olgu sunulmaktadır. 13 günlük erkek hasta, gözlerinde kayma ve tüm vücudunda titreme şikâyeti ile başvurdu. Miadında 4600 g olarak doğan olgunun fizik inceleme bulguları normaldi. Laboratuvar incelemede; Ca=4,6 mg/dl (8,510,5) P=7,6 mg/dl (2,26,5) ALP= 1617 U/L(30120), Mg=0.87mg/dl (1,52,1), PTH =56,4 pg/ml (1687) bulunurken, kan şekeri, elektrolitleri normaldi. Hastaya 200 mg/kg /doz intravenöz %10 Ca glukonat, hipomagnezemiye yönelik 2 doz 0,2 ml /kg % 50 MgSO4 tedavisi verildi. Mg değeri normale döndüğü halde (Mg=1.82) Ca düşüklüğü devam ettiğinden geç neonatal hipokalsemi nedenleri araştırıldı. Annenin Ca, P, ALP normal olmasına rağmen 25 OH vit D düzeyi 5 ng/ml ile çok düşük, PTH=226 pg/ml (2287 ng/ml) ile çok yüksek bulundu. Yapılan ultrasonografik değerlendirmede annede paratiroid adenomu tespit edildi. Annedeki hiperparatiroidiye bağlı geç neonatal hipokalsemi düşünülen olguya; günde 0.125 mcg kalsitriol ve kalsiyum tedavisi başlandı. Tedavinin 7. gününde serum Ca düzeyi normale geldi. 3 ay sonraki kontrolünde Ca=10,3 mg/dl, P=5,7 mg/dl, ALP=981 U/L, PTH=21 pg/ml bulundu. Geç neonatal hipokalseminin nedeni olarak D vitamini eksikliğine sekonder hiperparatiroidi ve paratiroid adenomu nadiren karşımıza çıkmaktadır. Kapalı yaşam tarzı nedeniyle güneşe yetersiz maruz kalan gebelerde vitamin D eksikliğinin ortaya çıkabileceği ve bunun geç neonatal hipokalsemiye neden olabileceği bu olgu ile vurgulanmak istendi.

LATE ONSET NEONATAL HYPOCALCEMIA SECONDARY TO MATERNAL VITAMİN D DEFICIENCY AND PARATHYROID ADENOMA

Year 2007, Volume: 1 Issue: 2, 37 - 41, 01.04.2007

Abstract

Excessive phosphate intake, intestinal calcium malabsorption, hypomagnesemia, maternal hyperparathyroidism, maternal vitamin D deficiency can cause late onset neonatal hypocalcemia. In this paper we present a boy who has late onset hypocalcemia secondary to maternal vitamin D deficiency and parathyroid adenoma. A thirteen day old boy was admitted to hospital with the complaint of trembling and flickering in the eyelids. He was term and 4600 g of weight and his physical examination was normal. In laboratory investigation; Ca = 4.6 mg/dl (8.510.5) P=7.6 mg/dl (2.2-6.5) ALP= 1617 U/L, Mg=0.87mg/dl (1.5-2.1), PTH =56.4 pg/ml , serum glucose and electrolytes was normal. 200 mg/kg/dose %10 Ca gluconate and for hypomagnesemia 0,2 ml/kg %50 MgSO treatment was adjusted. Despite his magnesium level was normal (Mg= 1.82 mg/dl) after the theraphy, hypocalcemia persisted so the other causes of hypocalcemia evaluated. Maternal laboratory investigation reveals us severe 25OH vit D deficiency (< 5 ng/ml) and secondary hyperparathyroidism (PTH=226 pg/ml), her Ca, P, ALP, Mg levels was in normal ranges. In the ultrasonographic examination of maternal parathyroid gland, parathyroid adenoma detected. Oral calcium and calcitriol 0.125 mcg/ day theraphy adminestered and at the seventh day of theraphy patient's serum Ca; P, ALP, Mg levels was normal. Parathyroid adenoma secondary to hyperparathyroidism due to maternal vitamin D deficiency is a rare cause of late onset neonatal hypocalcemia but it should be necessarily considered that in the populations which women could not utilize sunshine adequately because of their lifestyle, ethnicity and religion, maternal vitamin D deficiency and neonatal hypocalcemia can occur easily
