Abstract
Peritoneal dialysis (PD)-related peritonitis is a frequent complication. PD units should be aware of all possible pathogens and share their experience about prevention and optimal management. Uncommon bacteria, a special group with crescent incidence in PD practice, may require singular considerations. A case of peritonitis due to Ewingella americana, a rare human pathogen, is reported, with a favorable outcome. To date, only three other cases have been described in the literature. New evidence is necessary for a better understanding of this pathogen and its consequences in PD modality.
Highlights
Peritonitis is a frequent and potential serious complication of peritoneal dialysis (PD), directly related to adverse outcomes, including technique failure and mortality [1, 2]
A 45-year-old female patient on PD for the past 2 years was admitted to the hospital with diffuse abdominal pain and vomiting
To the best of our knowledge, this is the fourth worldwide peritonitis caused by this organism and the first ever reported in Portugal
Summary
Peritonitis is a frequent and potential serious complication of peritoneal dialysis (PD), directly related to adverse outcomes, including technique failure and mortality [1, 2]. Prevention of PD-associated peritonitis should, be a focus of every PD unit. Knowing the source of peritonitis, including transmission patterns of pathogens, is essential for a personalized approach when it comes to retraining the patient after an infection. Coagulase-negative staphylococcal species and Staphylococcus aureus, known colonizers of human skin, are responsible for the majority of PD-related peritonitis cases [3, 4]. On the contrary, show increasing relevance in our daily practice and must be dealt with care, in patients from impoverished or rural environments, where habitational context takes a special importance
