Summary

Diagnosing intestinal tuberculosis (TB) is challenging due to nonspecific symptoms and similar endoscopic findings to Crohn's disease (CD). Early differentiation is crucial as steroids benefit CD but harm intestinal TB.

Area of Science:

  • Gastroenterology
  • Infectious Diseases
  • Transplant Surgery

Background:

  • Tuberculosis (TB) incidence is rising in Spain, influenced by HIV/AIDS, immunotherapy, and immigration.
  • Intestinal TB presents with nonspecific symptoms and endoscopic findings, complicating diagnosis.
  • Distinguishing intestinal TB from Crohn's disease (CD) is critical due to opposing treatment implications.

Observation:

  • Endoscopic findings suggestive of intestinal TB include circular ulcers, small diverticula, and sessile polyps.
  • These lesions can mimic those seen in Crohn's disease (CD).
  • A case of intestinal TB in a renal transplant recipient highlights diagnostic challenges.

Findings:

  • Definitive diagnosis requires confirmation of caseating granulomas and/or acid-fast bacilli.

  • Polymerase chain reaction (PCR) on endoscopic biopsy specimens is recommended for detecting Mycobacterium tuberculosis.
  • Endoscopy is vital for establishing a suspected diagnosis of intestinal TB.

    • Implications:

    • Accurate differentiation between intestinal TB and CD is essential for appropriate patient management.
    • Steroid therapy, beneficial for CD, can be detrimental in intestinal TB.
    • Improved diagnostic strategies are needed for this rare but serious condition, particularly in immunocompromised patients.
