Abstract

BACKGROUND: The aim of this study was to assess the effect of periprocedural antibiotic treatment with roxithromycin on circulating cell adhesion molecules and restenosis after coronary stent implantation. METHODS: Case-control study enrolling 25 consecutive patients submitted to coronary stenting for stable, single-vessel coronary artery disease, treated with 300 mg roxithromycin once daily for 5 days, starting 2 days before the procedure (group R). Twenty-five patients, matched for lesion site, length and diameter, as control group (group C). The serological status for Chlamydia pneumoniae (CP) infection (IgG, ELISA) was assessed in all patients. The plasma concentrations of soluble intercellular adhesion molecule-1 (sICAM-1), E-selectin and C-reactive protein at 1 month after coronary stenting were compared with baseline values. Binary restenosis (> or = 50%) was also evaluated at 6 months. RESULTS: sICAM-1 significantly decreased at 1 month in group R vs group C (371 +/- 181 vs 573 +/- 273 ng/ml, p = 0.005). This decrease was more evident in patients with a positive serology for CP (CP+) (group R 373 +/- 131 vs group C 597 +/- 255 ng/ml, p = 0.014). Antibiotic treatment had no effects on circulating E-selectin levels at 1 month (56.7 +/- 97 vs 49.8 +/- 62 ng/ml, p = 0.54). The restenosis rate (9/50, 18%) was similar in the two groups (group R 5/25 [20%], group C 4/25 [16%]). The restenosis rate was similar in the CP+ vs CP- group (6/35 [17%] vs 3/15 [20%]). CONCLUSIONS: A short course of treatment with roxithromycin at the time of coronary stenting induces a significant reduction in the sICAM-1 levels at 1 month but apparently does not influence the restenosis rate.
