The clinicomorphological correlations in Schoenlein-Henoch nephropathy in children.
Clinicomorphological analysis has been performed in Schoenlein-Henoch nephropathy. Various clinical symptoms are accompanied by morphological changes of variable type and severity. Electron microscopy is a major tool for evaluating these changes. It relatively frequently modifies the diagnosis made by light microscopy. It mainly concerns class I and VI changes (according to a grading system of the International Study Group of Kidney Diseases in Childhood). It was shown that late prognosis was largely determined by the type and severity of morphological changes. Varying severity of changes in individual glomeruli in the same specimen requires in each case a comparison of results obtained by electron microscopy with those obtained by light microscopy in semithin sections. In three children biopsy was repeated. Progression of morphological changes was found in one child. He developed renal failure. In one child morphological changes on first biopsy did not differ from those on second biopsy. Repeated biopsy was performed due to the presence of hypertension. In one child with persistent proteinuria repeated biopsy showed marked attenuation of morphological changes.
