Exostosin 1 (EXT1) and exostosin 2 (EXT2)-associated membranous nephropathy (MN) may be associated with active autoimmune disease. We encountered an elderly man who presented with EXT1/EXT2-associated lupus-like MN with full house immune deposits, monoclonal gammopathy of uncertain significance and Sjögren's syndrome. The patient exhibited various other immune abnormalities. Although he did not fulfill the criteria of clinical systemic lupus erythematosus (SLE), he met a stand-alone renal criterion of the Systemic Lupus International Collaborating Clinics (SLICC) 2012. Whether or not a stand-alone renal criterion with EXT1/EXT2 positivity, as in the present patient, can efficiently guide decisions regarding the diagnosis and treatment of SLE remains a clinical dilemma.

Background: This study evaluated the efficacy of rituximab (RTX) in primary membranous nephropathy (PMN) patients with incomplete remission and drug dependence after long-term use of calmodulin inhibitors (CNIs). It aims for complete clinical and immunological remission, and cessation of CNI dependence.
Methods: Thirty-six patients were enrolled in the study with two groups: drug-dependent and partial remission or immune non-remission group.

Background: Particulate matter (PM2.5) has been implicated in the development of membranous nephropathy (MN), but the underlying mechanism has yet to be fully understood. Oxidative stress is an essential factor of PM2.

Neuron-derived neurotrophic factor (NDNF) was discovered as a target antigen in membranous nephropathy (MN) caused by syphilis. However, there have been few reports of NDNF-positive MN in Japan. A 19-year-old female patient was admitted to our hospital with nephrotic syndrome and acute kidney injury.

Methods: We designed a retrospective study using the CureGN database to compare individuals with adolescent-onset glomerular disease relative to individuals with older and younger age at onset.
