ABSTRACT It is known that renal failure is a poor prognostic marker for survival in Wegener's granulomatosis (WG). We investigated the longterm outcome of patients with WG who have severe renal disease requiring dialysis.
We performed a retrospective analysis of 104 patients with WG followed at our institution between 1982 and 1997. Twenty-three patients who required dialysis were studied in detail to determine outcomes and factors that influenced survival and restoration of renal function.
Of 23 dialysis dependent patients with WG, 11 died (Group 1). 7 either remained dialysis dependent or received successful renal transplants (Group 2), and 5 substantially recovered renal function (Group 3). Mean serum creatinine at the end of a mean followup period of 38.4 months for Group 3 was 1.8 mg/dl. There was no apparent difference between groups in regard to disease profile, e.g., distribution of organ involvement or serum creatinine when renal impairment was first recognized (mean serum creatinine for groups: 1: 3.0 mg/dl; 2: 5.6 mg/dl; 3: 5.5 mg/dl) and peak serum creatinine prior to dialysis (means for groups: 1: 9.5 mg/dl; 2: 10.5 mg/dl; 3: 9.6 mg/dl). Infection secondary to immunosuppression was the leading cause of death in Group I patients.
Because the clinical profile and degree of renal failure, as judged by serum creatinine, did not differ among patients who did or did not regain dialysis independent renal function, we recommend aggressive immunosuppressive therapy in all cases of active WG with acute rapidly worsening renal failure, regardless of the severity of renal impairment.

    ABSTRACT: To estimate the incidence of and survival rates for WG, microscopic polyangiitis (MPA), Churg-Strauss syndrome (CSS) and PAN within a defined population in southern Sweden. Cases were retrieved using hospital records and a serology database. All new cases of WG, MPA, CSS and PAN between 1997 and 2006 were included, provided they met pre-defined criteria, and were followed until 30 June 2008. The study area comprised two health care districts with a total population of 641 000. The standardized mortality ratio (SMR) was estimated using Swedish population data as a reference. A total of 140 (WG, 63; MPA 65; CSS 6; and PAN 6) cases (52% women) with a median age of 67.6 (range 20-96) years fulfilled the inclusion criteria. The annual incidence per million of the population (95% CI) was estimated to be 9.8 (7.4-12.2) for WG, 10.1 (7.7-12.6) for MPA and 0.9 (0-1.7) for both CSS and PAN. The highest incidence was found in patients aged >or=75 years (79.1/million). The 1- and 5-year survival rates were 87.8 and 71.6% for all patients, but lower for MPA (80 and 55%) compared with WG (95 and 83%; P = 0.001), although the difference was not significant in the multivariate analysis. The SMR was 2.77 (95% CI 2.02, 3.71) for all patients. The incidence of WG and MPA was equal in our district, but there was a difference in survival rates related to age and renal function. A progressive increase in age-specific incidence rates was observed.

    ABSTRACT: Despite important therapeutic improvements, permanent organ failure may develop in primary systemic vasculitides and affect the heart, the lungs, and especially the kidneys. In systemic vasculitides associated with antineutrophil cytoplasmic antibodies (AASV), end-stage renal failure develops in 20% of cases. Renal transplantation became a beneficial option in these patients, with a graft and patient survival comparable to that in nondiabetic patients. This review summarizes the current knowledge on indications and contraindications for renal transplantation in AASV and discusses the impact of posttransplant immunosuppression on the course of the patients.

    ABSTRACT: Pauci-immune glomerulonephritis is rare in African Americans (AA) and the clinical presentation and treatment outcomes of vasculitis have not been well described. We identified patients who were 2-92 years of age between 1983 and 2011 with a diagnosis of biopsy-proven pauci-immune glomerulonephritis (GN) at any point during their disease course. Comparing AA to Caucasian patients, we examined demographics, clinical features at presentation, treatment and outcomes of relapse, end-stage renal disease (ESRD), and death. Of the 672 patients, 75 were AA with the remainder being Caucasian. Compared to Caucasians, disease onset in AA was at an earlier age (52 vs. 57 years, p = 0.05) and was more often myeloperoxidase (MPO)-anti-neutrophil cytoplasmic antibody (ANCA) positive (71% vs. 54%, p = 0.01). AA patients had a shorter median time between onset of symptoms and biopsy compared to Caucasians [median (IQR): 0.23 (0.00, 1.22) months vs. 0.66 (0.00, 3.62) months, p = 0.003]. Median [Interquartile range (IQR)] follow-up in months was 28 (5, 52) in AA and 26 (10, 55) in Caucasian patients. Median estimated glomerular filtration rate was similar at presentation (21 vs. 22ml/min/m(2)). Both groups had similar induction treatment regimens. There was less favorable treatment response among AA compared to Caucasians for initial treatment resistance (28% vs. 18%, p = 0.05) and complete remission (72% vs. 82%, p = 0.05). There were no differences in the number of renal relapses or number of deaths between the 2groups. Overall, in multivariable analyses controlling for age, race, ANCA type, and entry serum creatinine, there were not differences by race in treatment response, renal relapse, ESRD, or death over the entire time of follow-up. AA patients with pauci-immune GN are younger and more often MPO-ANCA positive compared to Caucasians. Despite a shorter time to diagnosis for AA patients, there were no differences compared to Caucasians in treatment response, ESRD, renal relapse, or death rates by race over the entire duration of follow-up.
