Limb girdle muscular dystrophy type 2A presenting with cardiac arrest

Area of Science:

• Neurology
• Pulmonology
• Genetics

Background:

• Respiratory failure is a known complication of progressive neuromuscular disorders, commonly Duchenne dystrophy.
• Limb-girdle muscular dystrophy (LGMD) can also lead to respiratory compromise, though less frequently.
• Acute decompensation is often triggered by infections, but cardiopulmonary arrest is rare.

Purpose of the Study:

• To report an unusual presentation of limb-girdle muscular dystrophy type 2A (LGMD2A).
• To highlight the successful management of cardiopulmonary arrest in LGMD2A using noninvasive ventilation.
• To demonstrate the efficacy of bilevel positive airway pressure (Bi-PAP) in maintaining ventilation.

Main Methods:

• Case report of a male patient diagnosed with LGMD2A.
• Documented presentation with cardiopulmonary arrest secondary to an upper respiratory tract infection.
• Treatment involved nocturnal noninvasive intermittent positive pressure ventilation via a Bi-PAP device.

Main Results:

• The patient experienced cardiopulmonary arrest, an uncommon presentation for LGMD2A.
• Nocturnal Bi-PAP ventilation significantly improved the patient's symptoms.
• Quality of life was enhanced without requiring invasive respiratory support.

Conclusions:

• LGMD2A can present unusually with cardiopulmonary arrest.
• Nocturnal nasal Bi-PAP ventilation is an effective and less restrictive option for managing respiratory insufficiency in LGMD patients.
• This approach can maintain adequate ventilation and improve patient outcomes.
