Background Infection-related glomerulonephritis with IgA deposits (IRGN-IgA) is being more widely recognized but the precise epidemiology and outcome is lacking, particularly in Europe. We aimed to assess clinical, pathologic and outcome data of IRGN-IgA. Methods Clinical and outcome data from patients from 11 French centers over the 2007-2017 period were retrospectively collected. We reviewed pathologic patterns and immunofluorescence of renal biopsies and evaluated C4d expression in IRGN-IgA. We analyzed correlation between histological presentation and outcome using the Chi square test (qualitative data) and Kruskal-Wallis test (quantitative data). Results Twenty-seven patients (23 men, mean age: 62 ± 15 years) were included. Most of them had a Staphylococcus aureus infection (77.8%) and 44.4% were diabetic. At the time of biopsy, 95.2% had haematuria, 48.1% had a serum creatinine >4 mg/dL, and 16% had a hypocomplementemia. The most common pathologic presentation included mesangial (88.9%) and endocapillary proliferative glomerulonephritis (88.9%) with interstitial fibrosis with tubular atrophy (IF/TA) (85.1%). Diffuse and global glomerular C4d expression, found in 17.8% of the cases, was most frequently observed in biopsies with acute or subacute pattern and associated with a shorter delay between infection and renal biopsy compared to segmental and focal staining. After a median follow-up of 13.2 months, 23.1% died, 46.2% had persistent renal dysfunction and 15.4% reached end-stage renal disease. Renal outcome was correlated to IF/TA severity. Conclusions Infection-related glomerulonephritis with IgA deposits is usually associated with Staphyloccus infections and mainly affects adult men. This entity has a poor prognosis which is correlated to interstitial fibrosis and tubular atrophy severity.
