Abstract

The distribution of electron dense deposits in the glomerulus was scrutinized by electron microscopy in 34 cases of membranoproliferative glomerulonephritis (MPGN). Seven cases underwent serial biopsies. Results are summarized as follows. (1) Mesangial deposits (MD) and subendothelial deposits (SEND) were demonstrated in nearly all biopsy specimens. Intramembranous deposits (IMD) and subepithelial deposits (SEPD), which had hitherto been considered uncommon in MPGN, were also seen in over three- fourths of the specimens. (2) According to these findings, Burkholder's Type III MPGN, characterized by the frequent presence of SEPD, seems not to be essential in the classification of MPGN. In contrast, Strife's type III MPGN, defined by the disruption of the glomerular basement membrane (GBM), appears to be appropriate for the classification, because the cases diagnosed as Strife's type III showed quite peculiar histology among the MPGN. (3) In most cases having undergone serial biopsies, cellular proliferation in the glomeruli was more improved at the second biopsy than at the first, which probably resulted from intensive medications such as the combined therapy of corticosteroids, immunosuppressants, and anticoagulants.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
