ANALYSIS OF FOUR-HOUR GROWTH HORMONE PROFILES AFTER ONSET OF SLEEP IN NORMAL AND GH-DEFICIENT CHILDREN: A STANDARDIZATION OF THIS SIMPLE TEST FOR CLINICAL USE

Year 2001, Volume: 54 Issue: 3, 195 - 200, 30.09.2001

Abstract

The study comprised three groups of 131 prepubertal children. Group A included 55 healthy children and Group 8 included 66 children with GHD. Group C included 10 children with growth
retardation but normal GH response to pharmacological tests with flat GH-sleep testing compared with those of Group A. All children except Group A underwent two pharmacological
stimulation test for selection of patients. Spontaneous GH secretion was estimated by taking integrated 30 minutes blood samples for the first 4 - hour period of nocturnal sleep. The mean 4 - hour integrated GH concentration (ICGH), number of peaks (>5ng/ml) and the peak amplitude were calculated on 1048 occasions of sampling. The sensitivity of sleep test was defined by the percentage of true positive results. The mean ICGH, peak number and peak amplitude in the control group were 5.77+1.22, 3.98 + 1.37 and 15.91 + 2.2 ng/ml
respectively. The mean ICGH was 2.14+0.26 ng/ml in Group B and 3.12+0.6 ng/ml for Group C. There was concordance between GH response to pharmacological stimulation and short time sleep testing in 58 of 66 GHD patients. Thus the sensitivity of the test is 87.7 %. in conclusion short time sleep test is safe, reliable and practical for clinical use. Four-hour sleep study should be especially indicated when GH responses to provocative testing are inconsistent with observed growth pattern. Long term sleep testing can
be considered as a research tool rather than clinican one.

Abstract

Bu çalışmada normal çocuklarda derin uykunun ilk 4 saatinde bilydme hormonu (BH) profilinin değerlendirilmesi ve bu verilerin BH eksikliği olan hastalar ve ndrosekretuvar disfonksiyonu
olan hasta grubu ile karşılaştırılarak testin standardizasyonunu yapmak amaçlandı. çalışmada toplam 131 prepubertal olgu 3 grup halinde değerlendirildi, Grup A’da 55 sağlık çocuk, Grup B’de BH eksikliği tanısı alan 55 olgu ve Grup C’de boy kısalığı olan ancak farmakolojik uyarı testlerine yeterli yanıt veren 10 olgu değerlendirildi. Grup A dışındaki tüm olguların en az iki farmakolojik uyart testiyle BH yanıtlar: değerlendirildi, Uyku profili sırasında 30 dakikalık aralarla 4 saat boyunca örnekler alındı. Ortalama 4 saatlik BH yoğunluğu (ICGH) pik sayısı (>5ng/ml) ve pik amplitid toplanılan 1048 örnek üzerinden hesaplanan. Testin sensitivitesi Grup B’nin sonuçları ile karşılaştırılarak gerçek pozitif sonuçların yüzdesi ile hesaplandı).
Kontrol grubunu oluşturan Grup A’da sırası ile ICGH, pik sayısı ve pik amplitddd 5.77( 1,22, 3.98(1,37 ve 15.91(2,2ng/ml olarak bulundu. Grup B ve C’de elde edilen sonuglar daha disukti.
Ortalama ICGH Grup B’de 2,14(0,26 iken Grup C’de 3.12(0.6ng/ml idi.BH eksikliği olan 66 olgudan 58’nin uyku profili sonuçları farmakolojik uyarı testi sonuçlarıyla uyumluydu
(sensitivite %87.7). Kısa süreli uyku testi güvenilir, uygulanımı kolay pratik bir testtir. Büyüme yanıtları ile farmakolojik uyart testi yanıtları uyumsuz olan olgularda 4 saatlik uyku profili özellikle denetlenmelidir. Uzun süreli uyku testleri kullanım zorlukları açısından günlük klinik uygulamadan çok araştırmalarda tercih edilmelidir.
