    Abstract:
    BACKGROUND: In patients with dilated cardiomyopathy (DCM) and severe congestive heart failure, immunoadsorption (IA) and subsequent IgG substitution leads to an acute and prolonged hemodynamic improvement. Goal of this study was to investigate the long-term effect of immunoadsorption on morbidity. METHODS: In a retrospective analysis of 34 patients (17 patients who have received immunoadsorption therapy and 17 control patients) were included. Inclusion criteria were DCM, left ventricular ejection fraction less than 35%, NYHA classes II-III. The average time after immunoadsorption was 3.0 years (median 2.3 years). Both groups did not differ concerning sex, age, duration of disease, medication, baseline ejection fraction and NYHA class. RESULTS: In patients who have received immunoadsorption (IA) the days of hospitalisation for congestive heart failure per year could be significantly reduced in contrast to the control patients (17.2 days prior to IA, 4.3 days after IA). Even if the procedural days for immunoadsorption were included there was still a significant reduction of hospitalisation if IA therapy was longer than 2.5 years ago. The days of hospitalisation increased gradually with time during the follow up period. IA induced an acute increase in EF (19.8-25.7%, p<0.01 vs. baseline). CONCLUSION: IA not only leads to an acute hemodynamic improvement in patients with DCM but may also reduce morbidity in these patients during the next 3 years.
