# A Rare Case of Peritoneal Dialysis-Associated Peritonitis Caused by Neisseria sicca

## TL;DR

A rare case of peritoneal dialysis-related peritonitis caused by Neisseria sicca is reported, highlighting the importance of timely diagnosis and treatment.

## Contribution

This paper presents a rare clinical case of Neisseria sicca causing peritonitis in a peritoneal dialysis patient.

## Key findings

- Neisseria sicca can cause peritonitis in peritoneal dialysis patients.
- Prompt treatment following ISPD guidelines led to a favorable outcome.
- Uncommon pathogens should be considered in immunocompromised individuals.

## Abstract

Peritonitis is a critical complication in peritoneal dialysis, often leading to peritoneal dialysis (PD) treatment failure. We present a rare case of Neisseria sicca (NS)-related peritonitis in a 47-year-old male with multiple comorbidities. Despite NS's infrequent association with infections, prompt diagnosis and antibiotic therapy based on International Society for Peritoneal Dialysis (ISPD) guidelines led to a favorable outcome. This case emphasizes identifying uncommon pathogens in immunocompromised individuals and highlights the importance of prompt treatment to prevent morbidity.
