BACKGROUND: Gaucher disease type 3 (GD3) is a lysosomal storage disease characterized by diverse neurological and systemic manifestations. Symptoms of ataxia, cognitive impairment, and other systemic symptoms profoundly impact daily activities and the quality of life for individuals living with the disease. Development of a conceptual model of disease for persons living with GD3 from birth to adulthood would enable objective monitoring of disease progression and assessment of treatment benefits.
METHODS: A targeted literature review, interviews with clinical experts, and interviews with individuals and their caregivers living in the UK and the US were carried out to understand the patient experience. Interviews were transcribed and de-identified data were analyzed to identify signs, symptoms, and impacts of ataxia, cognitive impairment, and other systemic impairments. A conceptual model was developed by integrating relevant signs, symptoms, and impacts experienced from birth through adulthood.
RESULTS: Review of symptoms and impacts of GD3 from three published scientific articles, and interviews with six clinical experts, 12 individuals living with GD3, and 12 caregivers, identified 58 patient experience concepts associated with GD3. Signs and symptoms associated with ataxia appear during the first 3 years of life and persist beyond 5 years of age, while signs and symptoms related to neurocognition appear later in life. Difficulty in shifting gaze and/or tracking objects, ataxia, tremors, memory problems, difficulty in processing new information, fatigue, and bone pain are most salient concepts for GD3. In patients aged ≤ 5 years, motor manifestations and symptoms were far more prevalent than neurocognitive signs and symptoms. Inability to work or perform at school, limited social and family engagements, restricted mobility (walking, driving, public transportation), and declining independence were the most important impacts on individuals with GD3.
CONCLUSIONS: Heterogeneity exists in GD3 manifestations, especially neuromuscular and neurocognitive signs, symptoms, and impacts, across all age ranges of individuals living with GD3. The conceptual model developed in the study provided a comprehensive understanding of the disease in individuals with GD3.
