C-reactive protein and other markers of inflammation among patients undergoing HELP LDL apheresis

Studies reveal important prognostic relationships between C-reactive protei n (CRP) and atherosclerotic complications. A prospective trial of familial hypercholesterolemic patients treated with Heparin-induced Extra-corporeal Low-Density Lipoprotein Precipitation (HELP, B. Braun Melsungen) therapy wa s undertaken to evaluate the short- and long-term effects on CRP. Four pati ents received LDL apheresis therapy on an alternate week basis for 6 months . Pre- and post-treatment serum high sensitivity (hs) CRP levels (IMx(R), A bbott Laboratories), LDL-C, triglycerides, and fibrinogen were measured. Pr e- and post-treatment mean serum levels of LDL-C were 281 +/- 76 and 98 +/- 34 mg/dl; triglycerides 191 +/- 64 and 123 +/- 50 mg/dl; fibrinogen 332 +/ - 46 and 117 +/- 31 mg/dl, respectively. Before and after apheresis mean se rum levels of hsCRP were 8.99 +/- 7.88 and 3.15 +/- 3.16 mg/ml, respectivel y, representing a 65% decrease. After 6 months of therapy, pre-treatment hs CRP showed an overall mean level decrease of 49%. Preliminary results indic ate that LDL apheresis results in a rapid and long-term decrease of serum h sCRP levels. (C) 2001 Elsevier Science Ireland Ltd. All rights reserved.
