Tuberculous enteritis
Clinical Classification Guidelines
Inclusion Terms

- Tuberculosis of intestine (large) (small)
Medical Intelligence & Overview
Tuberculous enteritis is a form of intestinal tuberculosis caused by the bacterial infection Mycobacterium tuberculosis. It primarily affects the small and large intestines, leading to inflammation and associated symptoms. This condition is part of the broader spectrum of tuberculosis infections and requires careful diagnosis and management. Although primarily linked to tuberculosis in the lungs, the bacteria can spread to the gastrointestinal tract through the bloodstream or lymphatic system.
Causes & Symptoms
Clinical Causes: Infection with Mycobacterium tuberculosis bacteria Spread of tuberculosis bacteria from the lungs or other infected sites Ingestion of contaminated food or water in rare cases People with weakened immune systems are at higher risk
Key Symptoms: Persistent abdominal pain Chronic diarrhea or constipation Unexplained weight loss Fever and night sweats Fatigue and weakness Abdominal tenderness and swelling Possible rectal bleeding Signs of intestinal obstruction in severe cases
Diagnostic & Treatment
Diagnosis Path: The diagnosis of tuberculous enteritis involves a combination of clinical evaluation, laboratory tests, and imaging. Techniques include endoscopy with biopsy, which can reveal granulomatous inflammation characteristic of tuberculosis, as well as microbiological tests such as culture or PCR to detect the bacteria. Imaging studies like abdominal X-rays or CT scans may show bowel wall thickening or lymphadenopathy. Blood tests, including tuberculin skin test or interferon-gamma release assays, can support diagnosis, especially in conjunction with other findings.
Treatment Protocols: Treatment typically involves a long-term course of anti-tuberculous medication. Standard therapy may include drugs such as isoniazid, rifampin, ethambutol, and pyrazinamide, administered over several months. Monitoring for side effects and ensuring medication adherence are essential components of management. In some cases, surgical intervention may be necessary to address complications like bowel obstruction or abscess formation. Supporting care with nutritional support and managing symptoms are also important parts of treatment.
