Analysis of Cases With Tuberculous Peritonitis: a Single-Center Experience

Abstract

Background/Aims: Tuberculous peritonitis (TP) is a rare form of tuberculosis and is caused by peritoneal involvement with Mycobacterium tuberculosis. A distinctive correlation exists between socioeconomic state and disease prevalence. We aimed to evaluate the clinical, laboratory, and radiological findings of patients with TP. Materials and Methods: We conducted a retrospective study in patients with peritoneal tuberculosis from January 2004 to October 2008 at Yuzuncu Yil University Medical School Education and Research Hospital. During this time, the data of 21 patients (17 females) with TP were reviewed. Results: Fever, abdominal pain, and anorexia were the most common symptoms. An analysis of ascites showed lymphocyte predominance and low albumin gradient in all patients. Patients with TP had a median ascites adenosine deaminase (ADA) level of 139 U/L (range, 25 to 303U/L). Peritoneal involvement (wet peritonitis) was seen in all the cases. Following 6-month administration of combined anti-TBC treatment, mean serum CA-125 levels were within the normal range among patients who had previously higher serum CA-125 level. Mortality rate in the total cases was 4.6%. Conclusion: Peritoneal tuberculosis should be considered in the differential diagnosis of exudative ascites in eastern Turkey. A high level of suspicion is required, especially in high-risk populations living in rural areas. ADA seems to be a sufficient, safe, and inexpensive method to perform the diagnosis of peritoneal tuberculosis. Serum CA-125 levels may play a key role to support the diagnosis as well as disease management of TP.
