Spontaneous Bacterial Peritonitis by Burkholderia cepacia Complex: A Rare, Difficult to Treat Infection in Decompensated Cirrhotic Patients

IntroductionBurkholderia cepacia complex (Bcc) is non-fermenting Gram-negative bacillus and has been rarely reported to cause spontaneous bacterial peritonitis (SBP) in decompensated cirrhosis.ObjectiveThis study was done to evaluate the clinical presentation of cirrhotic patients with SBP due to Bcc and to determine its impact on clinical outcome.MethodsThis is a retrospective, observational study conducted during the period from 1st January 2013 through 31st March 2015. Medical records and microbiology laboratory files were reviewed to identify all cases of Bcc associated SBP among patients hospitalized at the liver intensive care unit and analyzed.ResultsDuring the study period, out of 252 SBP patients, 11 (4.3%) patients with a positive ascitic fluid culture for Bcc were identified. Pain abdomen was the predominant symptom present in 9 (81%) patients followed by hepatic encephalopathy in 7 (63%) patients. Acute kidney injury (AKI) was universally present, seen in 6 (54%) patients at the time of presentation and 4 (36%) patients developed AKI during hospital stay. The mean CTP score was 11.2 ± 1.1 (10-13), and the mean MELD was 24.3 ± 5.9 (14-35). The mean SOFA and APACHE II score at presentation were 11 ± 4.2 (4-18) and 19.4 ± 5.2 (11-28), respectively. A total of 8 (72%) patients (6-ACLF, 2-NASH) succumbed to the illness during hospitalization due to severe sepsis and multiorgan dysfunction and 3 (27%) patients are doing well on follow-up after 3 months.ConclusionSBP caused by Bcc has been rarely reported in cirrhotic patients. This organism is intrinsically resistant to third generation cephalosporins, which are the initial antibiotic of choice for SBP patients, hence associated with multi organ failure and high mortality rates.
