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.
A 47-year-old female, with multiple comorbidities, presented with a cough of two months, loss of weight and appetite. She was treated for pneumonia. A chest X-ray showed bilateral reticulonodular opacities. She was noted to have a vague central abdominal mass and a systolic murmur over the mitral region. Ultrasonography and computed tomography of the abdomen showed an omental mass and loculated ascites. Oesophagoduedenoscopy showed antral gastritis and during colonoscopy the surgical team was unable to advance the scope beyond 40 cm due to external compression. An echocardiogram showed a right atrial mass and a pericardial effusion over the posterior wall. A possible diagnosis of atrial myxoma was made. Sputum acid-fast bacillus was negative. The patient was treated empirically for disseminated tuberculosis and scheduled for bronchoscopy by the pulmonology team. The patient showed remarkable improvement after day 7 of anti-tuberculosis medication. GeneXpert study came back as positive. CT abdomen and echocardiogram repeated after 2 weeks of treatment showed reduction in the mass.
