MPO-ANCA–associated glomerulonephritis with immune complex deposition and membranous features in a patient with Sjögren’s syndrome: a case report

Key takeaways

This is a report on a single patient with Sjogren's syndrome, a disease where the immune system attacks the glands that make tears and saliva. The patient developed inflammation of the kidney filters with two patterns at the same time, one driven by an antibody called MPO-ANCA and one from immune deposits in the filter wall. One patient cannot show how often this happens or which treatment works best. It is useful mainly as a warning that these two kidney patterns can appear together.
