Lifetime Impact Study for Achondroplasia (LISA): Findings from an observational and multinational study focused on health-related quality of life in individuals with achondroplasia in Latin America

Abstract

PurposeThe multisystem clinical manifestations and complications of achondroplasia, the most common form of disproportionate short stature, can cause functional impairment and psychosocial burden. The Lifetime Impact Study for Achondroplasia (LISA), aimed to assess health-related quality of life and medical resource utilization among Latin America patients with achondroplasia. MethodsData were collected from individuals aged 3 years and above in Argentina, Brazil, and Colombia between 2018 and 2021. A total of 172 patients participated in the study. ResultsChildren with achondroplasia reported lower scores compared with average stature children in Quality of Life in Short Stature Youth (QoLISSY) and Pediatric Quality of Life Inventory (PedsQL) questionnaires, with the greatest impact on physical and social domains. Among adolescents, a significant percentage reported pain, 10.3% experienced pain in 3 or more sites. Adults scored lower than the reference population in the EQ-5D-5L Visual Analog Score, and a considerable portion reported moderate to severe anxiety/depression, pain or discomfort, and mobility problems. The Nottingham Health Profile (NHP) revealed poor health status in terms of energy, pain, and mobility. Medical events, particularly musculoskeletal and connective tissue disorders were reported, resulting in high medical resource utilization. ConclusionOverall, the Lifetime Impact Study for Achondroplasia study provides extensive data on health-related quality of life, psychosocial impact, and health care resource utilization among individuals with achondroplasia in Latin America. The findings confirm a significant burden of illness across multiple domains for these individuals.
