Fatigue in adults with Osteogenesis Imperfecta

Area of Science:

• Medical research
• Bone diseases
• Patient quality of life

Background:

• Osteogenesis Imperfecta (OI) is a genetic disorder characterized by bone fragility.
• Associated symptoms include blue sclerae, dentinogenesis imperfecta, hearing loss, ligamentous laxity, and short stature.
• Fatigue is frequently reported by OI patients, irrespective of skeletal deformity severity, impacting their quality of life.

Purpose of the Study:

• To investigate the prevalence and severity of fatigue in adults with Osteogenesis Imperfecta.
• To compare fatigue levels in OI patients with control populations.
• To determine if fatigue is a significant factor affecting the quality of life in OI patients.

Main Methods:

• The study utilized the Fatigue Severity Scale (FSS) questionnaire.
• Data was collected via a mobile phone application from 151 adult patients diagnosed with various types of OI.
• FSS scores were compared against two control groups from America (n=20) and the Netherlands (n=113).

Main Results:

• A total of 99 OI patients (72 with OI type 1, 13 with OI type 3, 14 with OI type 4) completed the study.
• The mean FSS score for the OI cohort was 4.4, significantly higher than the control groups' scores (2.3 and 2.9).
• Approximately 65% of OI patients reported experiencing at least moderate fatigue, compared to the control populations.

Conclusions:

• Fatigue is a prevalent and significant issue for patients diagnosed with Osteogenesis Imperfecta.
• This study provides the largest dataset to date on fatigue in OI patients, demonstrating a clear elevation in fatigue levels compared to controls.
• Further research into the causes and management of fatigue in OI is essential for improving patient care and quality of life.
