A retrospective descriptive study conducted at our institution between May 1, 2017, and March 15, 2022. The primary endpoint was to determine the clinical cure for patients who received C/T for documented infection while on RRT. The secondary endpoints were the microbiologic cure, 30-day infection recurrence, and 30-day crude mortality. Of the 27 patients who met the inclusion criteria, 17 (63%) were males, median age was 69 (62 - 82) years, and weight 67 (57 - 79) kg. The majority of patients had pneumonia 19 (70.4%) followed by bacteremia 5 (18.5%). Multidrug resistant Pseudomonas spp. was the causative organism of infection in 22 subjects (81.5%). Clinical cure was achieved in 17 subjects (63%). Of the 14 subjects who had their culture repeated, 10 (71.4%) patients had microbiologic cure vs. 4 (28.5%) patients who had a microbiologic failure (p = 0.327). 30-day infection recurrence occurred in 6 (35.3%) patients of the clinical cure group and 2 (20%) patients in the clinical failure group (p = 0.362), while mortality occurred in 5 (29.4%) subjects vs. 7 (70%) in both groups, respectively (p = 0.049). The most frequently used doses of C/T were 1.5 g IV q8h while undergoing continuous venovenous hemodiafiltration and 0.75 g IV q8h while undergoing hemodialysis (p = 0.209). The median duration of therapy was 9 (4.5 - 13) days in the clinically cured group vs. 5 (3.75 - 5.5) days in those who had clinical failure (p = 0.038). There was no adverse event reported using these doses during the study period. The used doses of C/T in this study were higher than those approved by the U.S. FDA, while clinical success is uncertain. Larger outcomes and pharmacokinetics studies are needed to establish effective dosing and therapy duration.
