Summary
Obstructive sleep apnea caused severe hypoxemia, leading to ischemic hepatitis and organ failure in an obese young man. Continuous positive airway pressure treatment improved his condition, supporting the link between nocturnal desaturation and hypoxic hepatitis.
Area of Science:
- Internal Medicine
- Pulmonology
- Gastroenterology
Background:
- Obesity is a growing public health concern associated with numerous comorbidities.
- Obstructive sleep apnea (OSA) is a common condition linked to cardiovascular and metabolic disturbances.
Observation:
- A young, obese male presented with ischemic hepatitis, coagulopathy, acute renal failure, and encephalopathy.
- The patient exhibited severe, unexplained diurnal arterial oxygen desaturation (77-99%) without signs of heart failure or hypovolemia.
Findings:
- Clinical diagnosis of obstructive sleep apnea (OSA) was confirmed by polysomnography, revealing frequent apneas and hypopneas with profound nocturnal oxygen desaturation.
- Treatment with continuous positive airway pressure (CPAP) via nasal mask led to the amelioration of clinical manifestations associated with nocturnal hypoxemia.
Implications:
- This case supports the hypothesis that severe arterial hypoxemia secondary to OSA can directly cause hypoxic hepatitis.
- Highlights the importance of considering and diagnosing OSA in patients with unexplained organ dysfunction, particularly in the presence of obesity and hypoxemia.
- Suggests CPAP therapy as an effective treatment for OSA-related complications, including hypoxic hepatitis.
