Abdominal Tuberculosis When Standard Antitubercular Therapy Has Not Achieved Adequate Response
Standard antitubercular therapy does not produce the expected clinical response in every patient with abdominal tuberculosis. When weekly monitoring over 4–6 weeks reveals insufficient improvement, clinical escalation is required — particularly in recurrent disease, suspected drug resistance, or serious illness.
Previous regimen & failure criteria
Prior treatment: A full course of antitubercular therapy — a 2-month intensive phase of four drugs (rifampicin, isoniazid, ethambutol, pyrazinamide) followed by a 4-month continuation phase of two drugs (rifampicin and isoniazid).
- Goals that were not achieved (escalation triggers):
- Resolution of symptoms
- Weight gain
- Improving haemoglobin
- Fall in C-reactive protein (CRP) levels
Next-line approach
In cases of recurrent disease, drug resistance, or serious illness, the continuation-phase regimen is modified — the complete protocol specifies which adjustments apply and under what conditions. The full structured regimen is available via the link below.
