Tuberculous peritonitis
Clinical Classification Guidelines
Inclusion Terms
- Tuberculous ascites
Medical Intelligence & Overview
Tuberculous peritonitis, also known as tuberculous ascites, is an infection of the lining of the abdominal cavity caused by the bacteria Mycobacterium tuberculosis. This condition often develops when tuberculosis spreads from the lungs or other parts of the body to the peritoneum—the membrane lining the abdominal organs. Recognizing the symptoms and understanding the causes of this condition are important for appropriate diagnosis and management.
Causes & Symptoms
Clinical Causes: Infection with Mycobacterium tuberculosis bacteria Spread from active tuberculosis in the lungs or other organs Inhalation of airborne bacteria that gradually infect the peritoneum Poor immune system functioning, which may increase susceptibility
Key Symptoms: Abdominal swelling or distension Persistent abdominal pain or discomfort Unexplained weight loss Fever and night sweats Loss of appetite General fatigue Ascites, which is the accumulation of fluid in the abdomen
Diagnostic & Treatment
Diagnosis Path: Diagnostic procedures often include imaging tests such as ultrasound or CT scans to detect fluid buildup and abdominal abnormalities. Laboratory analysis of ascitic fluid can reveal the presence of tuberculosis bacteria, and special tests like adenosine deaminase (ADA) levels or polymerase chain reaction (PCR) help confirm the diagnosis. A biopsy of the peritoneal tissue may also be performed for definitive confirmation.
Treatment Protocols: Treatment generally involves a prolonged course of anti-tuberculous medications, which may include drugs such as isoniazid, rifampin, ethambutol, and pyrazinamide. In some cases, removal of excess fluid through paracentesis—draining the fluid from the abdomen—may be necessary to relieve discomfort. Monitoring and supportive care are essential to manage symptoms and prevent complications, with healthcare providers guiding any adjustments in therapy.
