CRP and infection: In the univariable analysis, age, intensive care unit (ICU) admission, eGFR, need for kidney replacement therapy (KRT) at diagnosis (dialysis), C-reactive protein level, lymphocyte count at ANCA-GN diagnosis, and prophylaxis with trimethoprim−sulfamethoxazole (TMP/SMX) were significantly associated with the risk of severe infection during follow-up (Table S4).
