AZITHROMYCIN DECREASE SALIVA CALPROTECTIN IN PATIENTS WITH PERIODONTAL DISEASES.

Abstract

Objective: Calprotectin is a calcium binding heterocomplex protein which appear to have regulatory functions in the inflammatory process. Epithelial cells which expressing calprotectin are more resistant to bacterial invasion . In acute phase inflammatory reactions calprotectin is detectable in elevated levels. The aim of the present study is to detect the calprotectin level in saliva in patients with periodontal disease (chronic and aggressive periodontitis and gingivitis) and to follow calprotectin level during azithromycin treatment. Methods and materials: In nine healthy patients without systemic disease and malignancy whole unstimulated saliva was investigated. Salivary calprotectin levels were measured by enzyme-linked-immunosorbent using a commercial kit (ELISA Hycult Biotech). Azithromycin treatment was taken as 500 mg (2 x 250 mg tabls.) once daily at 10.00 am for 4 consecutive days. Results: At baseline Day levels of calprotectin ranged between 1.45 and 2.97; median 2.19. On Day 5 (first day after azithromycin treatment) the salivary calprotectin levels decreased in 6 of the patients. The measured values at Day 10 were more similar to those at Day 5, than those at Day zero. This was confirmed by the values of the average median of calprotectin. Conclusion: We present the first study with the application of antibiotic and measurement the calprotectin levels before, during and after azithromycin intake with no side effects reported. Measuring calprotectin levels could benefit the monitoring of antibiotic treatment efficacy in patients with gingivitis and periodontitis.
