    Abstract:
    BACKGROUND: Refractory peritonitis is defined as failure of clearance of peritoneal fluid despite 5 days of appropriate antibiotic therapy. Catheter removal decreases morbidity and mortality. Data on the outcomes of refractory peritonitis and of reinitiation of peritoneal dialysis (PD) in this group of patients are sparse. The present study analyzed etiology, outcomes, and prognostic factors of refractory peritonitis as well as survival of the reinitiation of the technique. METHODS: This was a single-center retrospective study that included 90 patients of refractory continuous ambulatory PD (CAPD) peritonitis at a tertiary care center in North India. We collected information regarding symptomatology, causes, prognostic factors, and outcomes of refractory peritonitis. RESULTS: Ninety patients suffered 93 episodes of refractory peritonitis. Fungal peritonitis was the most common cause of refractory peritonitis. Twenty nine (31%) episodes were culture-negative. We observed no difference between culture-positive and culture-negative peritonitis. Out of 90 patients, 54 (60%) recovered while 36 (40%) died. Septic shock at presentation alone was significantly associated with mortality in our study. The immediate mortality of refractory peritonitis is high. Even in patients who were shifted to permanent hemodialysis, 33% died in the first 3 months. Mean duration of technique survival after reinitiation was 23 months (1 - 85 months). Among the 12 patients who were reinitiated on CAPD, 5 patients had technique failure due to refractory peritonitis or ultrafiltration (UF) failure. CONCLUSION: Refractory peritonitis is associated with significant morbidity and mortality despite catheter removal. Reinitiation is confounded by residual infection, which is a concern for poor technique survival, and high immediate mortality.
