Henoch-Schönlein anaphylactoid purpura nephropathy: electron microscopic lesions mimicking acute poststreptococcal nephritis. 1978

R E Urizar, and J K Singh, and T Muhammad, and O Hines

The clinical, laboratory, and histologic features of a patient with Henoch-Schönlein syndrome are presented. The skin biopsy examination showed "leucocytoclastic vasculitis." Kidney tissue demonstrated deposits of IgG, C3, and fibrinogenfibrin by fluorescence microscopy in the mesangium and the peripheral glomerular basement membrane in a granular-nodular pattern. These correlated well with areas of mesangial hyperplasia and polymorphonuclear leucocyte infiltration seen by light and electron microscopy. Several well delineated, variably sized, subepithelial electron dense deposits flanked by polymorphonuclear leucotytes adherent to the glomerular basement membrane were seen in two of the four glomeruli examined by electron microscopy. The significance of these findings is discussed. A detailed ultrastructural evaluation of patients with Henoch-Schönlein nephropathy may yield information about the frequency of subepithelial deposits and perhaps may help to clarify the pathogenesis of this syndrome.

UI	MeSH Term	Description	Entries
D007674	Kidney Diseases	Pathological processes of the KIDNEY or its component tissues.	Disease, Kidney,Diseases, Kidney,Kidney Disease
D008297	Male		Males
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy

D009393	Nephritis	Inflammation of any part of the KIDNEY.	Nephritides
D011695	IgA Vasculitis	A systemic non-thrombocytopenic purpura caused by HYPERSENSITIVITY VASCULITIS and deposition of IGA-containing IMMUNE COMPLEXES within the blood vessels throughout the body, including those in the kidney (KIDNEY GLOMERULUS). Clinical symptoms include URTICARIA; ERYTHEMA; ARTHRITIS; GASTROINTESTINAL HEMORRHAGE; and renal involvement. Most cases are seen in children after acute upper respiratory infections.

D005455	Fluorescent Antibody Technique	Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.
