Evidence for the involvement of the IgE-basophil-mastocyte system in human acute post-streptococcal glomerulonephritis

Abstract

Several findings reveal the involvement of the IgE-basophil-mastocyte-platelet-activating-factor (PAF) system in human acute post-streptococcal glomerulonephritis. In the acute phases of the disease there is a transient, marked reduction in the circulating metachromatically staining basophils, indicating an in vivo basophil degranulation. The blood reservoirs of PAF are depleted. The number of metachromatic mastocytes in renal biopsy samples was very low and morphological aspects of degranulation were present. In vitro, we demonstrated basophil degranulation and PAF release in presence of exogenous streptococcal Ags after recovery. These findings suggest that the IgE-basophil-mastocyte-PAF system may play a role in human pathology, as has been shown in immune complex (Ic) deposition in acute serum sickness in rabbits.
