To the Editor,
Coronavirus infection becomes an important problem in public health. Within the past few years, many emerging coronavirus infections occur including to COVID-19.[1] The coronavirus-induced nephropathy is an interesting issue in clinical nephrology. The nephropathological finding is various.[2] In animal, the glomerulopathy by immune complex is an important clinical problem.[3] In fact, immune complex plays important role in many kinds of renal pathology and the underlying pathogenesis might be explained by nanostructure analysis.[4] Here, the authors focus interest on the coronavirus-antibody immune complex. The molecular nanostructure analysis by standard nanomedicine technique as used in the previous reported[5] was done. For prediction of the nanostructure of coronavirus-antibody immune complex, referencing sizes for coronavirus (120–160 nm),[1] immunoglobulin[6] and renal glomerulus (15–30 nm) diameters[5] are referred to. Based on nanostructure viewing of predicted immune complex, the size of coronavirus-antibody immune complex is 135–190 nm. This size is significant larger than glomerular pore size (4–4.5 nm)[4] but smaller than renal tubule (12–50 microns).[7] Therefore, there is a chance that the immune complex of coronavirus-antibody can cause glomerular pathology. This can also explain the observation of no virus in excreted urine during infection.[8]
