    The study enrolled 31 patients with peritoneal dialysis-associated peritonitis, including 23 cured and 8 with relapsing PDAP.

    Conventional culture detected pathogens in 64.5% of cases, while 16S rDNA sequencing increased detection rates to 67.8%, and combined methods reached 83.9%.

    Relapsing PDAP is associated with gut-derived bacterial translocation and immune dysregulation, indicating a complex pathogenesis beyond persistent infection.

  • 4

    Proteomic analysis revealed distinct biomarker levels between cured and relapsing groups, highlighting CCL28, CD40, uPA, and NRTN as significant.

  • 5

    The findings suggest that 16S rDNA sequencing can complement traditional methods, enhancing diagnostic accuracy for relapsing PDAP.
