zithromax and Gingival-Hemorrhage

The results of recent published studies focusing on the effect of azithromycin as an adjunct to scaling and root planing (SRP) in the treatment of chronic periodontitis are inconsistent. We conducted a meta-analysis of randomized controlled clinical trials to examine the effect of azithromycin combined with SRP on periodontal clinical parameters as compared to SRP alone. An electronic search was carried out on Pubmed, Embase and the Cochrane Central Register of Controlled Trials from their earliest records through December 28, 2014 to identify studies that met pre-stated inclusion criteria. Reference lists of retrieved articles were also reviewed. Data were extracted independently by two authors. Either a fixed- or random-effects model was used to calculate the overall effect sizes of azithromycin on probing depth, attachment level (AL) and bleeding on probing (BOP). Heterogeneity was evaluated using the Q test and I(2) statistic. Publication bias was evaluated by Begg's test and Egger's test. A total of 14 trials were included in the meta-analysis. Compared with SRP alone, locally delivered azithromycin plus SRP statistically significantly reduced probing depth by 0.99 mm (95% CI 0.42-1.57) and increased AL by 1.12 mm (95% CI 0.31-1.92). In addition, systemically administered azithromycin plus SRP statistically significantly reduced probing depth by 0.21 mm (95% CI 0.12-0.29), BOP by 4.50% (95% CI 1.45-7.56) and increased AL by 0.23 mm (95% CI 0.07-0.39). Sensitivity analysis yielded similar results. No evidence of publication bias was observed. The additional benefit of systemic azithromycin was shown at the initially deep probing depth sites, but not at shallow or moderate sites. The overall effect sizes of systemic azithromycin showed a tendency to decrease with time, and meta-regression analysis suggested a negative relation between the length of follow-up and net change in probing depth (r = -0.05, p = 0.02). This meta-analysis provides further evidence that azithromycin used as an adjunct to SRP significantly improves the efficacy of non-surgical periodontal therapy on reducing probing depth, BOP and improving AL, particularly at the initially deep probing depth sites.

One-stage full-mouth scaling and root planing (FM-SRP) in combination with systemically administered azithromycin was shown to be clinically and bacteriologically effective in the treatment of chronic periodontitis. However, FM-SRP requires 2 hours for completion. Azithromycin has a long half-life. Therefore, if SRP of the full mouth is performed within 7 days while an effective concentration of azithromycin remains in the gingiva, the effects may be the same as FM-SRP. The aim of this study was to compare the clinical and bacteriologic effects of FM-SRP and partial-mouth scaling and root planing (PM-SRP) in patients with chronic periodontitis, which was performed in three sessions within 7 days, during the effective half-life of systemically administrated azithromycin.. Thirty adult subjects with chronic periodontitis were randomly divided into three groups (FM-SRP, PM-SRP, and control). A clinical examination was conducted to record the probing depth, clinical attachment level gain, bleeding on probing, gingival index, and volume of gingival crevicular fluid; bacterial samples were obtained before treatment and 1, 3, 6, 9, and 12 months thereafter. Quantitative and qualitative analyses were performed using the polymerase chain reaction-Invader method.. All clinical parameters showed better improvement in FM-SRP and PM-SRP groups compared to the control group, with no significant differences between the two test groups. Periodontal bacteria were well controlled in the two test groups, but they tended to increase gradually 3 months after treatment in the control group.. PM- and FM-SRP demonstrated comparable clinical and bacteriologic results.

To assess the effect of systemic azithromycin as a supplement to scaling and root planing (SRP) in the treatment of aggressive periodontitis (AgP).. Twenty-four individuals (13-26 years old) underwent a plaque control program, and then were treated with SRP. Subjects were assigned randomly into two groups; the test group used 500 mg azithromycin once a day for 3 days, whereas the control group used a placebo. Clinical variables were assessed at baseline, 3, 6, 9, and 12 months. The periodontal status at baseline and 12 months was compared using the Wald test, and adjusting for the effect of clustering of teeth within subjects.. There were no significant differences in visible plaque, gingival bleeding, and supragingival calculus between groups throughout the study. Periodontal probing depth (PPD) and clinical attachment level improved significantly from baseline to 12 months in both groups, with the test group showing significantly more reduction in mean PPD compared with controls (2.88 mm versus 1.85 mm, respectively, p=0.025). Subjects administering azithromycin showed a higher percentage of teeth with attachment gain >or=1 mm (81.34 versus 63.63, p=0.037), whereas the controls had higher percentage of teeth with attachment loss >or=1 mm (11.57 versus 2.24, p=0.015).. The adjunctive use of azithromycin has the potential to improve periodontal health of young patients with AgP.

Antibiotic therapy can be used in very specific periodontal treatment situations such as in refractory cases of periodontal disease found to be more prevalent in smokers. This study was designed to determine the efficacy of azithromycin (AZM) when combined with scaling and root planing (SRP) for the treatment of moderate to severe chronic periodontitis in smokers.. Thirty-one subjects were enrolled into a 6-month randomized, single-masked trial to evaluate clinical, microbial (using benzoyl- DL-arginine naphthylamine [BANA] assay), and gingival crevicular fluid (GCF) pyridinoline cross-linked carboxyterminal telopeptide of type I collagen (ICTP) levels in response to SRP alone or SRP + AZM. At baseline, patients who smoked > or =1 pack per day of cigarettes who presented with at least five sites with probing depths (PD) of > or =5 mm with bleeding on probing (BOP) were randomized into the test or control groups. At baseline and 3 and 6 months, clinical measurements (probing depth [PD], clinical attachment loss [CAL], and bleeding on probing [BOP]) were performed. GCF bone marker assessment (Ctelopeptide [ICTP] as well as BANA test analyses) were performed at baseline, 14 days, and 3 and 6 months.. The results demonstrated that both groups displayed clinical improvements in PD and CAL that were sustained for 6 months. Using a subject-based analysis, patients treated with SRP + AZM showed enhanced reductions in PD and gains in CAL at moderate (4 to 6 mm) and deep sites (>6 mm) (P <0.05). Furthermore, SRP + AZM resulted in greater reductions in BANA levels compared to SRP alone (P <0.05) while rebounds in BANA levels were noted in control group at the 6-month evaluation. No statistically significant differences between groups on mean BOP and ICTP levels during the course of the study were noted.. The utilization of AZM in combination with SRP improves the efficacy of non-surgical periodontal therapy in reducing probing depth and improving attachment levels in smokers with moderate to advanced attachment loss.
