The objectives of this two part prospective study were to evaluate the effects of statins on C-reactive protein (CRP), butyrylcholinesterase (BChE), lipids, and the relationships between these parameters. Subjects enrolled in this study were separated into two cohorts. The first group (study 1) consisted of 37 subjects converted from pravastatin to cerivastatin. The second group (study 2) consisted of 11 subjects with diabetes initiated on cerivastatin therapy. The subjects were followed for 12-weeks in the Lipid Clinic at David Grant Medical Center at Travis Air Force Base. CRP, BChE, total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglycerides (TG) were measured at baseline, 6-weeks, and 12-weeks. In study 1, CRP (p = 0.704) and BChE (p = 0.746) remained relatively stable over 12-weeks. The lipid panel changed significantly with TC (p < 0.001) and LDL (p < 0.001) decreasing and HDL (p = 0.017) increasing. Although TG declined numerically, it was not statistically significant (p = 0.649). A significant negative correlation was detected at baseline (r = −0.353, p = 0.032), but lost at 6-weeks and 12-weeks. In study 2, CRP declined by 42.9%, but was not statistically significant (p = 0.178). BChE remained relatively stable over 12-weeks (p = 0.666). TC (p < 0.001) and LDL (p < 0.001) declined and TG (p = 0.035) fluctuated over the course of the study. HDL increased, but it was not statistically significant (p = 0.396). Significant positive correlations were seen between CRP and TG (r = 0.908, p < 0.001) and BChE and TC (r = 0.721, P = 0.012) at baseline and BChE and TG (r = 0.64, p = 0.034) at 12-weeks. These results suggest that statin effects on CRP are independent of the lipid-lowering effects and switching statins may not affect CRP disposition. Cerivastatin does not appear to have effects on BChE activity. Lastly, a possible competitive relationship may exist between CRP and BChE. This is suggested by the negative correlation seen in study 1 and with the gain in correlation between BChE and TG as the correlation was lost between CRP and TG in study 2.
