Glomerular IgG subclasses in idiopathic and malignancy-associated membranous nephropathy
BACKGROUND In idiopathic membranous nephropathy (MN), antibodies directed towards the glomerular phospholipase A2 receptor (PLA2R) have mainly been reported to be of IgG4 subclass. However, the role of the different IgG subclasses in the pathogenesis of MN, both in idiopathic MN and in secondary cases, is still unclear. In this retrospective study, we test the hypothesis that the absence of glo...
متن کاملDissecting the relationships of IgG subclasses and complements in membranous lupus nephritis and idiopathic membranous nephropathy
Membranous lupus nephritis (MLN) and idiopathic membranous nephropathy (IMN) are kidney diseases with similar morphology, but distinct etiologies, both producing glomeruli with immune deposits. Immunoglobulins and complements, the main components of the deposits, can be detected by immunofluorescence (IF) microscopy. Previous researches characterized the immune deposits only individually, but n...
متن کاملRetrospective Study of Phospholipase A2 Receptor and IgG Subclasses in Glomerular Deposits in Chinese Patients with Membranous Nephropathy
BACKGROUND AND OBJECTIVES The research work in the past years showed that detection of phospholipase A2 receptor (PLA2R) antigen and its dominant IgG4 autoantibody in glomerular deposits of patients with membranous nephropathy (MN) was useful for the differentiation between primary MN (PMN) and secondary MN (SMN), but so far such research data from large Chinese patient series is little. Here, ...
متن کاملTherapy of membranous nephropathy associated with malignancy and secondary causes.
Membranous nephropathy (MN) most commonly is idiopathic, but secondary causes are common in children and in older adults. The most common secondary causes of MN in industrialized countries include malignancy and systemic lupus erythematosis. Infectious causes (hepatitis B, quartan malaria, schistosomiasis) remain the most common etiologies in endemic areas. In this article we describe the clini...
متن کاملMalignancy in Membranous Nephropathy: Evaluation of Incidence
BACKGROUND Membranous nephropathy (MN) can be associated with malignancy. However, the relative risk for malignancy remains unclear. It has been reported that higher numbers of inflammatory cells seen in the glomeruli at biopsy correlate with the occurrence of malignancy in patients with MN and might be used to direct screening. METHODS We examined the occurrence of malignancy in 201 MN patie...
