Insights
Prader Willi syndrome (PWS) patients face respiratory issues due to genetic factors. This review examines PWS respiratory complications and growth hormone
Area of Science:
- Genetics and Molecular Biology
- Pediatrics
- Pulmonology
Background:
- Prader Willi syndrome (PWS) is a genetic disorder caused by deletion or lack of expression of paternal chromosome 15 genes.
- PWS presents with hypotonia, abnormal respiratory/arousal responses to hypoxia/hypercapnia, scoliosis, and obesity, predisposing patients to ventilatory problems.
- Respiratory complications range from sleep-disordered breathing to aspiration and functional impairment.
Purpose of the Study:
- To review common respiratory complications in PWS patients.
- To synthesize literature on the impact of growth hormone (GH) therapy on respiratory parameters in PWS.
- To guide safe clinical management of PWS patients undergoing GH treatment.
Main Methods:
- Literature review of published studies.
- Synthesis of clinical data on PWS respiratory complications.
- Analysis of growth hormone's effects on respiratory function in PWS.
Main Results:
- PWS patients exhibit a spectrum of respiratory issues including sleep-disordered breathing and impaired ventilatory responses.
- Concerns exist regarding sudden death post-growth hormone initiation in PWS patients.
- Growth hormone's impact on respiratory parameters requires careful consideration.
Conclusions:
- Comprehensive understanding of PWS respiratory complications is crucial for safe management.
- Multidisciplinary care and careful monitoring are essential for PWS patients, especially during growth hormone therapy.
- Further research is needed to clarify the risks and benefits of growth hormone in PWS regarding respiratory health.
Abstract:
Prader Willi syndrome, resulting from the partial deletion or lack of expression of a region of genes on the paternal chromosome 15, has a number of phenotypic features which predispose affected patients to ventilatory problems. These include generalised hypotonia, abnormal arousal and ventilatory responses to hypoxia and hypercapnia, scoliosis and frequently, obesity. The spectrum of the resulting respiratory complications thus runs from sleep disordered breathing, to aspiration and respiratory functional impairment. While the use of growth hormone, in conjunction with multidisciplinary clinical management, is currently the cornerstone of clinical care of these patients, concerns have been raised following reports of sudden death shortly after growth hormone initiation. This review summarizes the respiratory complications commonly seen and draws together the published literature on the impact of growth hormone in relation to various respiratory parameters, aiming to provide the reader with the necessary information to manage these patients as safely as possible.
