Low serum albumin level, particularly a level below 28 g/l, is an independent predictor of venous thrombotic risk in patients with membranous nephropathy (MN). Lionaki et al. studied registry data from 898 patients with biopsy-confirmed idiopathic MN diagnosed between 1969 and 2007. Over a median follow-up of 37 months, 7.2% of patients had ≥1 thromboembolic event. Hypoalbuminuria at diagnosis was the only independent predictor of venous thromboembolic events on multivariate analysis.
