Ten patients with homozygous familial hypercholesterolaemia were treated with the recently introduced drug probucol (Lurselle; Mer-National) for 15-21 months. Xanthomas regressed or disappeared in most patients, angina lessened in two-thirds of cases and the ECG improved in half of those with pretreatment abnormalities. The mean fall in serum total cholesterol levels after 18 months of therapy was 27%. High-density lipoprotein cholesterol levels fell transiently in the early months of therapy but then returned to the pretreatment range. Plasma probucol levels varied between 20 micrograms/ml and 90 micrograms/ml, indicating good compliance, but did not correlate with the clinical or hypocholesterolaemic responses. Probucol was well tolerated by child and adult patients. The effects of probucol in this therapeutically resistant disorder were better than expected. Considered in relation to efficacy, safety, tolerance and convenience probucol appears to be the most satisfactory treatment for homozygous familial hypercholesterolaemia currently available.

Autoantibodies specific for malondialdehyde-modified LDL (MDA-LDL) represent potential biomarkers to predict cardiovascular risk. However, MDA-LDL is a high variability antigen with limited reproducibility. To identify peptide mimotopes of MDA-LDL, phage display libraries were screened with the MDA-LDL-specific IgM monoclonal Ab LRO4, and the specificity and antigenic properties of MDA mimotopes were assessed in vitro and in vivo. We identified one 12-mer linear (P1) and one 7-mer cyclic (P2) peptide carrying a consensus sequence, which bound specifically to murine and human anti-MDA monoclonal Abs. Furthermore, MDA mimotopes were found to mimic MDA epitopes on the surface of apoptotic cells. Immunization of mice with P2 resulted in the induction of MDA-LDL-specific Abs, which strongly immunostained human atherosclerotic lesions. We detected IgG and IgM autoAbs to both MDA mimotopes in sera of healthy subjects and patients with myocardial infarction and stable angina pectoris undergoing percutaneous coronary intervention, and the titers of autoAbs correlated significantly with respective Ab titers against MDA-LDL. In conclusion, we identified specific peptides that are immunological mimotopes of MDA. These mimotopes can serve as standardized and reproducible antigens that will be useful for diagnostic and therapeutic applications in cardiovascular disease.
