Anti-beta1-adrenoceptor (beta1AR) autoantibodies have been shown to be pathophysiologically important in idiopathic dilated cardiomyopathy (DCM). Treatment with intravenous immunoglobulin (IVIG) has shown beneficial effects in both DCM and ischemic cardiomyopathy. However, the underlying mechanism has not been clarified. In the present study, we therefore examined whether the improvement of cardiac function was due to neutralization of functional beta1AR autoantibodies by anti-idiotypic antibodies. Autoantibodies against the beta1AR was analysed in sera from patients with DCM and coronary artery disease (CAD) treated with IVIG or placebo before, 6 and 12 months. Six month after treatment, DCM patients showed increase in beta1AR autoantibodies, mostly in IgG1 and IgG2, whereas in CAD patients mostly in IgG2. No changes in beta1AR autoantibodies after 12 months were detected. In summary, our results indicate that improvement of cardiac function by IVIG is not due to neutralization of beta1AR autoantibodies.
