Zusammenfassung in Englisch (Abstract)
Immunoadsarptian (IA) and subsequent immunoglobulin (Ig) G substitution represent an additional therapeutic approach for stabilization of patients suffering from dilated cardiomyopathy (DCM). This therapeutic approach not only improves cardiac performance but also modulates myocardial inflammation the latter of which is possibly a cause of ventricular dysfunction in DCM.
25 patients with ejektion fraction (EF) < 30%, NYHA III-IV under stable medication was included. Of these, 12 patients were randomized for lA-therapy and subsequent IgG substitution at one-month intervals until month 3. Before and after IA right ventricular biopsies were obtained. From 13 patients (controls) without IA, biopsies wer also obtained. Anti-CD 3, -CD 4, -CD 8, -LCA, and HLA class-ll antigens were used. Two independent observers counted the number of immunopositive cells and analysis fibrosis as well as HLA class-ll antigen expresssion.
IA and IgG treatment induced significant improvement in left ventricular EF and induced a reduction of &beta-receptor autoantibody. In comparison to the findings before IA the number of CD 3-, CD 4-, CD 8-and LCA-positive cells was reduced significantly vs. baseline and vs. controls. The decline of inflammatory cells was paralleled by a decreased in HLA class-ll antigen expression. In both groups the degree of fibrosis remained unchanged during follow-up.
IA and subsequent IgG substitution mitigate the inflammatory process in the myocardium of DCM patients.
