Our study showed that in apparently normal adults the presence and the severity of proteinuria could be reflected by the peripheral neutrophil and monocyte counts, but not the lymphocyte count. These findings, together with the documented inflammatory basis of proteinuria and the diverse pathophysiological roles of differential leucocytes, suggest that peripheral differential leucocyte counting may be useful in predicting the course of an existing proteinuria. Perspective longitudinal follow-up studies are needed to test this presumption.
