In Reply to “‘atypical’ Anti-GBM Disease: Just Atypical, or Not Anti-GBM Disease at All?”

We read the Letter to the Editor by Ivković et al.1 in response to our article with interest and thank the authors for emphasizing that atypical anti-GBM nephritis remains a diagnosis of exclusion. Indeed, differential diagnoses, notably monoclonal immunoglobulin deposition disease and diabetic kidney disease, should be ruled out through a careful examination of light microscopy, immunofluorescence and, ideally, electron microscopy, along with the clinico-biological context.
