ObjectiveTo determine the auxological response to recombinant human growth hormone (rhGH) therapy in children with growth hormone deficiency (GHD) presenting at the National Institute of Child Health, Karachi, Pakistan.Study Design Observational study. Place and Duration of the Study: Department of Paediatric Endocrinology, National Institute of Child Health, Karachi, Pakistan, from January 2022 to December 2023.Methodology All pre-pubertal children with short stature aged 3-12 years diagnosed with GHD and who were prescribed rhGH therapy were included in the study. Children with any other underlying reason for short stature or any other comorbidity were excluded. Patients' demographics and baseline growth parameters were recorded in a pre-designed proforma. Patients were then followed up every three months till one year. Response to rhGH therapy was evaluated through comparison of growth parameters before and after one year of therapy.ResultsA total of 90 children including 47 (52.2%) males and 43 (47.8%) females with GHD were enrolled. Mean age of these patients was 7.92 ± 2.647 years. A statistically significant change in height (SD), Weight (SD), and BMI (SD) was observed before and after one year of therapy (p <0.001). Response to therapy in terms of height did not differ significantly with respect to gender (p = 0.955) or stimulated growth hormone levels (p = 0.911). However, response to rhGH therapy was significantly better in terms of increase in height, weight, and BMI in patients presenting earlier i.e. at age ≤8 years.ConclusionRecombinant human growth hormone therapy was effective in children with short stature to achieve desirable growth. Children diagnosed and treated at a younger age (≤8years) achieve better height outcomes as compared to those presenting late.Key Words Short stature, Growth hormone deficiency, Recombinant human growth hormone.
