Popis: Background:Indications to repeat renal biopsy (RB) in lupus nephritis (LN) are not unanimously acknowledged.Objectives:To evaluate the renal outcome of patients with LN undergoing a second RB.Methods:We retrospectively analyzed prospectively collected data of patients with LN followed up in four Italian referral centres for systemic lupus eryhtematosus. Serological and clinical information were retrieved according to a shared database. RB were classified according to ISN/RPS 2003 classification; chronicity (CI) and activity indexes (AI) were defined according to Austin et al. The primary renal outcome was renal failure, defined as serum creatinine (SCr)>1.0mg/dL with eGFRResults:Four-hundred and thirty-eight patients were recruited. One-hundred and three patients repeated RB after 6.1±4.7 (mean± SD) years from the first due to: protocol biopsy due to renal remission (Group 1, n=8); proteinuric flare (Group 2, n=51); worsened renal function (Group 3, n=26); partial renal response (Group 4 n=18). Patients undergoing a second RB were younger (pConclusion:Patients undergoing a repeated RB had more aggressive clinical and histological features already at first RB and developed renal failure more frequently. Among baseline features, uncontrolled hypertension had the strongest association with renal failure, thus suggesting that control of blood pressure since early stages is highly advisable.References:[1]Austin HA, et al.
