Peritonitis-associated with peritoneal dialysis following Ureaplasma parvum infection: A case report and literature review

We report a patient diagnosed with peritonitis due to a rare infection of Ureaplasma parvum after receiving peritoneal dialysis for two years. This microorganism rarely causes peritoneal dialysis-associated peritonitis (PDAP). This is the first case of PDAP caused by Ureaplasma parvum. In the present case, the pathogen was identified through next-generation sequencing of PD fluid samples. The patient was treated with intraperitoneal (IP) levofloxacin combined with vancomycin and oral clarithromycin which effectively improved her symptoms. This case creates awareness that Ureaplasma parvum can cause PDAP and can be diagnosed using next-generation sequencing(NGS).
