Crecimiento físico de niños con hiperplasia suprarrenal congénita perdedora de sal durante los dos primeros años de vida en el Instituto Nacional de Salud del Niño

Objective: To describe physical growth features in children with salt-wasting congenital adrenal hyperplasia (CAH) during their first two years of life, in the Endocrinology Service of the Peruvian National Children's Health Institute (CHI) in Lima, Peru. Materials and Methods: This is a retrospective, observational, and descriptive study. Fifty-five children with CAH underwent follow-up in the Endocrinology Service of the CHI from 2000 to 2016; data such as body weight and height were collected at birth time and every six months, as well as age at diagnosis, hydrocortisone and fludrocortisone doses, and growth velocity. Results: Fifty-five children with salt-wasting CAH were assessed, the diagnosis was more promptly made in females (median: 21 days) compared to males (median: 52 days). At birth, their average length was 0.07 ± 0.75 SD; at 6 months it was -1.67 ± 1.33 SD, and male subjects were more affected (-2.29 ± 1.18 SD; p= 0.022); at 12 months, this parameter was -1.84 ± 1.27 SD, and recovery was observed at 24 months (-1.51 ± 1.10 SD). Growth velocity values were -1.03 ± 1.62 SD and -0.89 ± 1.06 SD in the first and second years of life, respectively. Conclusions: Children with salt-wasting CAH who were followed-up at CHI had shorter length at 6- and 12- months of age, and their recovered at 24-monbths.
