Abstract Background Short stature is one of the main causes of children referral to pediatric endocrinologists. Common etiologies include idiopathic growth hormone deficiency (IGHD), small for gestational age (SGA), and idiopathic short stature (ISS). Objectives The aim of this study was to assess and compare the response of children with IGHD, ISS, and SGA to growth hormone (GH) therapy. Methods This was a mixed cohort study that included 40 children with short stature (classified into IGHD, ISS, and SGA) following up at Diabetes, Endocrine, and Metabolism Pediatric Unit (DEMPU), Cairo University Children’s Hospital. Ages ranged between 3 and 18 years. Recruited cases were evaluated for their 1-year response to GH therapy. In addition to history taking, physical examination, and anthropometric measurements, serum levels of IGF-1 were assayed at recruitment. Results Among the 3 groups, height gain (cm/year) was significantly higher in the IGHD group (6.59 cm/year), followed by the ISS (4.63 cm/year) and SGA groups (4.46 cm/year) (p = 0.039). Using the Bang criterion for first-year responsiveness to GH therapy, most cases (30/40, 75%) were considered poor responders. Conclusion There is a male predominance in children seeking medical advice for short stature. Starting GH therapy at an older age was associated with poor response. Children with IGHD respond better to GH therapy than those with ISS and SGA. |
