Abstract:
Rapid-onset obesity with hypothalamic dysfunction, hypoventilation, and autonomic dysregulation (ROHHAD) is a rare and potentially lethal disorder of respiratory control, autonomic, and hypothalamic dysfunction of unknown etiology. We report a 15-year-old girl with ROHHAD who developed hyperphagia and rapid weight gain of 16 kg between 2.5 and 4 years of age and cardiorespiratory arrest at 4 years. Initial polysomnography showed central sleep apnea and severe oxygen desaturations without hypoventilation. Mild obstructive sleep apnea and intermittent hypoxemia were identified at 4.5 years, following which nocturnal bilevel positive airway pressure therapy was initiated. At 6 years, she developed sleep-related hypoventilation, and subsequent polysomnograms continued to show obstructive sleep apnea and hypoventilation requiring bilevel positive airway pressure. Clinicians interpreting polysomnograms should become familiar with the evolution of sleep-disordered breathing in ROHHAD and that hypoventilation may develop over time. Our case highlights the importance of serial polysomnography in patients with ROHHAD and optimal ventilatory management.
