Physical, Mental, and Social Problems of Adolescent and Adult Patients with Achondroplasia

Patients with achondroplasia (ACH) require various medical interventions throughout the lifetime. Survey of health-related quality of life (HRQoL) in adult ACH patients is essential for the evaluation of treatment outcomes performed during childhood such as growth hormone administration and limb lengthening surgeries, but no study focused on the treatment strategy by analyzing HRQoL of ACH patients. The purpose of this study was to assess whether final height impacted on HRQoL and to evaluate what kinds of medical interventions were positively or negatively associated with HRQoL. We included 184 ACH patients (10–67 years old) who were registered in the patients’ associations or who had a medical history of the investigators’ institutions, and analyzed HRQoL by using Short Form-36 and patient demographics. Physical component summary (PCS) was significantly lower than the standard values in each age, especially in elderly populations, while mental component summary (MCS) was similar to the standard values. Role/social component summary was deteriorated only in elderly populations. The PCS was improved in the patients who had a height of 140 cm or taller (p < 0.001). The PCS and MCS were strongly associated with the past medical history of spine surgeries (p < 0.001 and p = 0.028, respectively). A treatment strategy would be planned to gain a final height of 140 cm or taller during childhood in combination with growth hormone administration and limb lengthening surgeries. Appropriate medical management for neurological complications of adult ACH patients is required to maintain physical and mental function.
