[Vascular purpura and other cardiovascular alterations in children with acute parvovirus B19 infection. Report of 3 personal cases].

Most frequent skin manifestation of parvovirus B19 infection is the erythema infectiosum (fifth disease; Sticker's disease). Vascular purpura (some cases of Henoch-Schönlein purpura) has been reported in virus infections such as infectious mononucleosis (Epstein-Barr virus), hepatitis B, cytomegalovirus etc., and human parvovirus B19 could be another cause. Clinical course, procedure of diagnostics and therapy in 3 own serologically established cases of vascular purpura or severe alterations of the blood circulation due to parvovirus B19 infection are presented. Parvovirus B19 (or other viruses) as a trigger for vascular purpura and alteration of the blood vessel wall and blood circulation could explain the childhood predominance and seasonal clustering of that disease. Furthermore an individual disposion (in form of special HLA type?) for the development of vascular purpura can be suggested.
