Outcomes of Adjunctive Therapy with Open Arthrotomy for Patients with Septic Arthritis Due to Melioidosis: A Retrospective Study

Am J Trop Med Hyg. 2024 Apr 30:tpmd230812. doi: 10.4269/ajtmh.23-0812. Online ahead of print.ABSTRACTMelioidosis is a potentially fatal infection caused by the bacterium Burkholderia pseudomallei. Septic arthritis caused by this infection is uncommon and difficult to treat. The role of adjunctive open arthrotomy in this type of infection has not yet been elucidated. We conducted a retrospective study of patients with microbiologically confirmed melioidosis between January 2002 and December 2022. Patients with a clinical condition of septic arthritis and positive cultures for B. pseudomallei were included. Comparisons were made between patients who received adjunctive therapy with open arthrotomy with conventional standard treatment and those who did not in terms of clinical outcomes and hospital expenditures. Of the 478 patients diagnosed with melioidosis microbiological confirmation, 81 patients had septic arthritis, accounting for 17% of cases. Among these patients, only 36 (44%) underwent adjunctive therapy with open arthrotomy. The 14-day and 30-day in-hospital mortality and length of hospital stays of patients who underwent adjunctive therapy with open arthrotomy were more favorable than those of patients who did not receive adjunctive therapy with open arthrotomy; however, the difference was not statistically significant. Patients who underwent adjunctive therapy with open arthrotomy had lower hospital expenditures (antimicrobial and non-antimicrobial costs) than those ...
