Insights
Fibrodysplasia ossificans progressiva (FOP) patients with scoliosis and breathing issues benefit from noninvasive ventilation (NIV). Long-term NIV improves quality of life and may extend survival, even with incomplete gas exchange correction.
Area of Science:
- Medical Genetics
- Pulmonology
- Rare Diseases
Background:
- Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disorder causing progressive heterotopic ossification.
- Scoliosis and thoracic deformity affect ~65% of FOP patients, leading to restrictive lung disease and respiratory failure.
- Sleep-disordered breathing and nocturnal hypoventilation are significant complications in FOP.
Purpose of the Study:
- To evaluate the efficacy and impact of long-term noninvasive ventilation (NIV) in children with FOP experiencing severe scoliosis and nocturnal hypoventilation.
- To assess the effects of NIV on sleep quality, respiratory exacerbations, quality of life, and survival in this patient cohort.
Main Methods:
- Case series reporting on 3 children with FOP, severe scoliosis, and sleep-disordered breathing.
- Treatment involved long-term home-based noninvasive ventilation (NIV).
- Outcomes assessed included tolerance, compliance, sleep quality, respiratory exacerbations, quality of life, and survival.
Main Results:
- Patients showed excellent tolerance and compliance with long-term NIV.
- NIV led to improved sleep quality and reduced acute respiratory exacerbations requiring hospitalization.
- A good quality of life and long-term survival were maintained, despite non-optimal correction of nocturnal hypoventilation.
Conclusions:
- FOP patients with nocturnal hypoventilation and respiratory exacerbations should be screened for NIV.
- Long-term NIV can improve quality of life and potentially prolong life expectancy in FOP patients.
- NIV offers significant benefits even when complete correction of nocturnal gas exchange is not achieved.
Abstract:
Fibrodysplasia ossificans progressiva (FOP) is an autosomal dominant rare disease characterized by progressive episodic multi-focal heterotopic ossification of skeletal muscle, ligaments, tendons, and fascia, associated with congenital malformation of the great toes. Progressive thoracic deformity with scoliosis is present in approximately 65% of patients, causing restrictive lung disease, respiratory failure, and premature death. We report 3 children who developed severe scoliosis and sleep-disordered breathing with nocturnal hypoventilation, and were treated with long-term noninvasive ventilation (NIV) at home. Despite a non-optimal correction of nocturnal alveolar hypoventilation due to the severity of the disease, tolerance and compliance with NIV were excellent, with an improvement in sleep quality, a reduction in acute respiratory exacerbations requiring hospitalization, the maintenance of a good quality of life, and long-term survival. In conclusion, patients with FOP should be screened for nocturnal hypoventilation and recurrent or severe respiratory exacerbations, in order to propose long-term NIV, which may be associated with a better quality of life, and may eventually prolong life expectancy, even in case of uncomplete correction of nocturnal gas exchange.
