Amaç: Düşük doz büyüme hormon tedavisi ile sağlanabilecek maddi kazanç ihtimalini ortaya koymak için bu çalışma planlandı. Olgular ve Metod: Büyüme hormonu eksikliği olan 97 çocuk 2 grupta incelendi. 1)Çalışma grubuna (n=39) rekombinant insan büyüme hormonu (rhGH) 0.15 mg/kg/ hafta dozunda verildi. 2)Kontrol grubuna (n=58), rhGH klasik doz olan 0.2 mg/kg / hafta dozunda verildi. Tüm olgular çalışma başlangıcında ve büyüme hormon tedavisinin 6. ve 12.aylarında değerlendirilip oksolojik kontrolleri yapıldı ve insülin benzeri büyüme faktörü (IGF-1) ile insülin benzeri büyüme faktörü bağlayıcı protein -3 (IGFBP-3) seviyeleri ölçüldü.

Bulgular: Kontrol grubu ile karşılaştırıldığında çalışma grubunda: Tedavinin 6.ayında IGF-1, IGFBP3, büyüme hızı (GV) ve büyüme hızı SDS (GVSDS) değerlerinde istatistiksel anlamlı fark bulunamazken, tedavinin 12.ayında kontrol grubunda GV ve GVSDS seviyeleri anlamlı yüksek bulundu. Bu fark kontrol grubunda bu dönemde gözlenen pubertal sıçramaya bağlandı. Her 2 grupta; GV ve GVSDS ile parental boy, hedef boy, IGF-1, IGFBP-3 değerleri arasında istatistiksel anlamlı fark bulunamadı.

Sonuç: Büyüme hormonu tedavisinde halen kullanılmakta olan konvansiyonel dozun azaltılması büyüme üzerinde anlamlı olumsuz etki yapmadığından daha düşük doz tedavi ile tedavi maliyetlerinde yaklaşık %20 civarında azalma sağlanabilir ki, bu tüm ülkeler için total tedavi harcamalarını azaltmada çok önemli bir kazanç olabilir.
