Resumen

Recombinant human insulin-like growth factor-1 (rhIGF-1) treatment studies of growth failure in absence of growth hormone (GH) signaling (GH insensitivity -GHI, Laron syndrome -LS, GH Receptor deficiency -GHRD) have taken place in many locations around the globe. Results from these trials are comparable, and slight differences reported can be attributed to specific circumstances at different research sites. rhIGF-I treatment studies of GHI in Ecuador included various trials performed on children belonging to the largest and only homogeneous cohort of subjects with this condition in the world. All trials were performed by the same team of investigators and, during study periods, subjects received similar nutritional, physical activity and medical advice. Combination of these inherent conditions most likely creates less sources of variability during the research process. Indeed, diagnosis, selection and inclusion of research subjects; methodology used; transport, storage and delivery of study drug; data collection, monitoring and auditing; data analysis, discussion of results, conclusion inferences and reporting, etc., were submitted to the same sources of error. For the above-mentioned reasons, we are hereby mainly covering conclusions derived from rhIGF-I treatment studies of Ecuadorian children whit GHRD due to homozygosity of a splice site mutation occurring at GHR gene, whose unaffected parents were both heterozygous for the same mutation. We also describe studies of rhIGF-I administration in adolescent and adult subjects with GHRD, from the same cohort and with the same genetic anomaly.
