Abstract:
Objective: To compare the CRP response to a standardized inflammatory stimulus in patients with history of stable or unstable CHD
Methods: Adjuvanted influenza sc vaccination (Inflexal y®) was given
to 60 adult male patients with quiescent CHD and well-controlled CV risk
factors who had presented at onset of CHD as stable CHD: silent or inducible
ischemia (group 1, n=26) or acute coronary syndromes (group 2; n=34).
hsCRP was determined by ELISA on plasma samples collected at baseline
and 48 hours after vaccination, according to the results of a pilot time-course
study performed in 5 volunteers.
Results: The patients were non diabetic, non-smokers, free of inflammatory
or other conditions that might presumably influence the immune response. The
groups were similar in prevalence of non-coronary atherosclerosis, history of
allergies, infections. CV risk factors and current use of CV drugs, including
aspirin (100%) and statins (90%), as well as age, BP, BMI and mean levels
of LDL-C, TG, HDL-C and median [25•75th perc] baseline hsCRP (group 1:
0.47 µg/ml [0.21-0.86] vs. group 2: 0.64 µg/ml [0.21-1.09]). Vaccination significantly augmented hsCRP in both groups (Wi1coxon test, p<0.01), without significant differences between groups in terms of absolute (0.12 µg/ml [0-0.29] vs 0.16 µg/ml [-0.02 - 0.41 ]) or percent (29% [0 - 81 %] vs 36% [-6 - 72%] changes (Mann-Whitney tests, both NS).
Conclusion: CHD patients with history of stable or unstable disease
respond similarly to a defined standardized inflammatory stimulus (influenza
vaccination) in terms of CRP change.
