Final height in a boy with achondroplasia treated with growth hormone- case report

Abstract

Achondroplasia is the most common genetic form of skeletal dysplasia in humans. It is characterized by short stature and skeletal disproportion. Patients with this condition have comorbidities, such as cardiovascular problems, spinal cord problems, hearing and dental problems as well as psychological issues. We report final height of 147 cm in a 17-year-old boy treated with growth hormone, however without improvement in body proportions. Surgical therapy for limb lengthening had been proposed, which the patient refused. At this age he developed hypertension and was referred to a cardiologist, nephrologist, as well as to an orthopedic surgeon and psychologist. Recently, a new treatment with vosoritide has been introduced, promising better height outcome, but uncertain phenotype improvement. Multidisciplinary approach is recommended for these patients and close monitoring during childhood, adolescence and adulthood. Genetic counseling is also advised.
