IgA vasculitis (IgAV) is a systemic vasculitis of the small vessels characterized by immune complexes including immunoglobulin A1 (IgA1) [1]. The clinical picture is a vascular purpura with or without joint, digestive and/or kidney involvement [2]. The acute, life-threatening complications of the disease include gastrointestinal involvement, while kidney damage is the most important chronic complication and the main cause of morbidity and mortality in patients [3]. Renal involvement can induce acute kidney injury which can lead to chronic kidney disease (CKD) and kidney failure with the need for extrarenal epuration or transplantation.
