Abdominal tuberculosis: a presumptive diagnosis

Area of Science:

• Infectious Diseases
• Gastroenterology
• Clinical Medicine

Background:

• Abdominal tuberculosis (TB) is a prevalent condition often posing diagnostic challenges.
• Microbiological confirmation of abdominal TB is frequently unattainable.
• Early identification of clinical and laboratory features is crucial for provisional diagnosis.

Purpose of the Study:

• To identify key clinical and laboratory features for early provisional diagnosis of abdominal TB.
• To guide early initiation of anti-tuberculosis chemotherapy.
• To improve diagnostic strategies in resource-limited settings.

Main Methods:

• Retrospective study of 12 patients diagnosed with abdominal TB over two years.
• Analysis of clinical presentations, laboratory findings, and treatment responses.
• Diagnosis often made by exclusion and response to therapy.

Main Results:

• Common presentations included chronic diarrhea (7 patients), progressive abdominal distension/ascites (4 patients), and abdominal swellings (1 patient).
• Seven patients exhibited malabsorption features, and nine had persistent pyrexia.
• Ascitic fluid was exudative in four patients; definitive diagnosis was challenging, with diagnosis based on exclusion and prompt response to anti-TB therapy.

Conclusions:

• A trial of anti-TB chemotherapy is justified in TB-endemic areas for patients with chronic diarrhea of unknown etiology or exudative ascites after excluding other causes.
• Prompt response to anti-TB therapy can be considered sufficient for diagnosing abdominal TB when histopathological or microbiological confirmation is not possible.
• Findings align with experiences from other Third World countries, highlighting the need for clinical acumen in diagnosing abdominal TB.
