Objectives: Tuberculosis remains a common infection and is often associated with non-specific constitutional symptoms or laboratory investigations regardless of site of manifestations. This study compares the profiles of abdominal tuberculosis (ATB) and pulmonary tuberculosis (PTB).
Methods: Patients with ATB (n=34, male-21, mean age 43.3 ± 16.0 years) diagnosed over a nine year period were identified from the National Tuberculosis registry and retrospectively reviewed. Comparisons were made with patients treated for PTB (n=163).
Results: The most commonly affected sites were the ileocecal regions, peritoneum and hepatobiliary system. Common clinical presentations were abdominal pain (61.8%), anorexia (44.1%), weight loss (55.9%), fever (41.1%) and abdominal distension (29.4%). Four patients had concomitant active PTB. Compared to PTB, patients with ATB had significantly lower serum haemoglobin (11.6 ± 2.4 vs. 12.6 ± 2.0 gm/dL, p=0.036) and higher rate of adverse events of antituberculous treatment (50% vs. 15.4%, p<0.001). There were no difference in prevalence of constitutional symptoms (fever, weight loss and anorexia), platelet level, albumin, total protein and erythrocyte sedimentation rate. Importantly, there was no difference in the treatment
response. More patients with ATB and concomitant active PTB had reported weight loss (100% vs. 36.7%, p=0.017).
Conclusion: There are differences in the profiles of ATB and PTB. Awareness of such differences can help to improve the understanding and management of this infection.
An 80 year old lady presented with signs and symptoms of sub-acute intestinal obstruction which failed conservative management. CT scan abdomen revealed circumferential ileum thickening with proximal bowel dilatation. Laparotomy and segmental resection was done. Pathological findings were suggestive of chronic granulomatous ileits with differential of Crohn's disease and gastrointestinal tuberculosis. The patient was presumed to have gastrointestinal tuberculosis and commenced on anti tuberculosis treatment despite inconclusive evidence for confirmation and showed marked clinical improvement.
Abdominal tuberculosis (TB) is common. But the diagnosis of abdominal TB is fraught with difficulties as it is often not possible to get a microbiological confirmation of the infection. We therefore undertook this study to highlight those pertinent clinical and laboratory features which would enable one to make a provisional diagnosis of abdominal TB early, to pave way for a trial of anti-tuberculosis chemotherapy.
