Sažetak
PURPOSE: To evaluate significance of clinical and histopathological prognostic factors for renal and patient outcome in AAV patient cohort. METHODS: Retrospective study included consecutive patients diagnosed with pauci-immune crescentic glomerulonephritis from January 2003 to December 2013. Primary outcome was combined endpoint patient death or progression to end- stage renal disease (ESRD). Secondary outcomes were patient survival and progression to ESRD (renal survival) singularly and disease relapse. Kaplan-Meyer survival analysis and multivariate Cox proportional hazard regression analysis were used to explore difference between phenotypes and finding significant predictors regarding outcomes. RESULTS: Out of 81 patients, 40.7% patients reached primary endpoint, 22.2% died, 29.6% reached ESRD and 16% relapsed during follow-up. Multivariate Cox proportional hazards regression-adjusted analysis found higher BVAS (HR 1.08, 95% CI 1.01-1.17, p = 0.042), higher baseline maximal serum creatinine (HR 1.02, 95% CI 1.01-1.03, p = 0.04) and lower haemoglobin (HR 0.97, 95% CI 0.95-0.99, p = 0.011) significantly associated with primary endpoint. Higher BVAS (HR 1.25, 95% CI 1.01-1.43, p = 0.001) and lower haemoglobin (HR 0.95, 95% CI 0.91-0.99, p = 0.008) were significantly associated with patient survival, while for renal survival, lower haemoglobin (HR 0.97, 95% CI 0.94-0.99, p = 0.041) and the need for acute haemodialysis (HR 3.15, 95% CI 1.20-8.26, p = 0.02) were significant predictors. On multivariate-adjusted analysis, no significant predictors for disease relapse were found. Kaplan-Meier survival analysis found no difference between clinical, serological and pathohistological phenotypes for all of the endpoints. CONCLUSIONS: Renal function at presentation, anaemia and BVAS should be included in prediction models for the outcomes for the AAV patients.
