title: [Serum concentrations of proteinase inhibitors, complement components and of acid alpha-1-glucoprotein in children with myocarditis (author's transl)].
abstract: We examined 4 panels of children and 40 control patients for their serum levels of the complement components C3, C4 and the C3 activator, the proteaseinhibitors alpha-1-antitrypsin, alpha-2-macroglobulin and acid alpha-1-glycoprotein. Children of the group with active myocarditis revealed the consumption of the complement system, increased protease inhibitors and elevated acid alpha-1-glycoprotein. Group 2, children with the clinical diagnosis chronic myocarditis or status post myocarditis showed in six of seven cases low complement levels and elevated alsGP. 4 children showed increased A1AT and five increased A2MG. In the third panel: status post myocarditis, we estimated in five of eight patients complement activation, 4 children showed increased A2MG and alsGP and in 3 cases elevated A1AT levels were detected. Group 4 children revealed no complement consumption and showed no increased levels for the other proteins estimated, with the only exception of 1 case with increased alsGP. The children of the control group showed normal levels for the six proteins. By means of the examinations an inflammatory process can be detected, tissue injury can be indicated and the participation of the immune system can be shown.
