A case of peritoneal dialysis-associated peritonitis caused by Rhodococcus pyridinivorans
Abstract
Background: Rhodococcus infections are exceedingly rare and largely reported in immunocompromised hosts, with no consensus on optimal therapy due to limited evidence.
Case presentation: This article reports for the first time a case of peritoneal dialysis-associated peritonitis caused by Rhodococcus pyridinivorans in a patient with diabetic nephropathy. The dialysate leukocyte count declined substantially with combination antimicrobial therapy, but complete normalization occurred only after replacing icodextrin with a glucose-based dialysate.
Conclusions: These findings support the use of combination regimens and emphasize the need to consider icodextrin-associated sterile peritonitis when dialysate abnormalities persist despite appropriate antimicrobial treatment.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
