A case of acute hypercapnic respiratory failure secondary to late onset nemaline rod myopathy: A multi-disciplinary approach.

Background: Nemaline rod myopathy (NRM) is a rare muscle disorder defined by muscle weakness, respiratory insufficiency, and dysphagia. Respiratory muscle involvement can lead to acute hypercapnic respiratory failure, posing significant challenges in management. Case presentation: Our patient is a 73-year-old male with a history of polymyositis, who presented with acute hypercapnic respiratory failure secondary to a suspected polymyositis flare. Despite initial management, the patient experienced complications, including dysphagia, thrombocytopenia, and altered mental status. Neurological consultations revealed conflicting opinions regarding the primary diagnosis, suggesting inclusion body myositis. The patient's condition continued to deteriorate, prompting discussions about prognosis and palliative care options. This case highlights the challenges in managing respiratory failure in patients with late-onset nemaline myopathy and the importance of multidisciplinary care in addressing complex medical needs. Conclusion: This case emphasises the complexity of managing respiratory failure in patients with late-onset nemaline myopathy and the significance of adopting a multidisciplinary approach. Timely interventions, including respiratory support, dysphagia management, and palliative care discussions, are vital in optimizing patient care and quality of life. Further research is warranted to elucidate optimal management strategies and improve outcomes in this patient population.
