Uso da doxiciclina no tratamento periodontal de pacientes diabéticos / Use of doxycycline in the periodontal treatment of diabetic patients ­ systematic review

O paciente diabético tem uma resposta desfavorável ao tratamento periodontal devido à alteração da resposta imunoinflamatória e da cicatrização. Tendo isso em vista, alguns estudos clínicos em humanos têm avaliado o efeito do uso de antibioticoterapia como coadjuvante ao tratamento periodontal. Portanto, objetivou-se realizar uma revisão sistemática para avaliar a eficácia da antibioticoterapia com doxiciclina no tratamento periodontal de pacientes diabéticos. A pesquisa compreendeu o período de dezembro de 1994 a janeiro de 2017. A revisão sistemática foi conduzida de acordo com as recomendações do Cochrane Collaboration. Os critério de seleção utilizado foi: estudos clínicos controlados randomizados que utilizaram a terapia antibiótica com doxiciclina no tratamento periodontal de pacientes diabéticos. As médias dos parâmetros clínicos periodontais foram comparadas entre os períodos iniciais e após o tratamento, entre o grupo-teste e o grupo-controle. Depois do processo de seleção, oito estudos clínicos controlados randomizados foram incluídos na revisão. Os resultados da maioria dos estudos selecionados com doxiciclina sistêmica não demonstraram benefícios adicionais, quando comparados com a raspagem isolada, nos parâmetros clínicos periodontais. Desta forma, pôde-se concluir que o número limitado de trabalhos, a heterogeneidade dos estudos e a grande variação de dosagem requerem a realização de outros estudos clínicos controlados randomizados para esclarecer controvérsias sobre o uso da doxiciclina como terapia coadjuvante ao tratamento periodontal mecânico em pacientes diabéticos.

The diabetic patient has an unfavorable response to periodontal treatment due to impaired immuno-infl ammatory response and healing. With this in view, some clinical studies have evaluated the effect of the use of antibiotic therapy as a adjuvant to periodontal treatment. Therefore, a systematic review was carried out to evaluate the efficacy of antibiotic therapy with doxycycline in the periodontal treatment of diabetic patients. The study comprised the period from December 1994 to January 2017. The systematic review was conducted according to the recommendations of the Cochrane Collaboration. The selection criteria used were: randomized controlled trials that used doxycycline antibiotic therapy in periodontal treatment in diabetic patients. The means of periodontal clinical parameters were compared between the initial and post-treatment periods, between the test and control groups. After the selection process, eight randomized controlled trials were included in the review. The results of most of the studies selected with systemic doxycycline did not demonstrate any additional benefits when compared to scaling alone, in periodontal clinical parameters. Therefore, it can be concluded that the limited number of studies, the heterogeneity of the studies, as well as the great variation of dosage, require the execution of other randomized controlled clinical studies to clarify controversies about the use of doxycycline as adjunctive therapy to mechanical periodontal treatment in diabetic patients.

Antibiotic therapy as an adjunct to scaling and root planing in smokers: a systematic review and meta-analysis

Abstract The aim of this study was to perform a systematic review and meta-analysis to examine the effect of systemic antibiotics in the periodontal treatment of smokers. The selection criteria were as follows: controlled randomized clinical trials; studies published in English; studies with smoker patients diagnosed with chronic periodontitis; patients without systemic diseases; studies that used systemic antibiotic therapy associated with periodontal treatment; studies that presented results for the test and control groups and assessments of clinical periodontal parameters, such as probing depth (PD), bleeding on probing (BOP), and clinical attachment level (CAL). The differences in average weights were calculated with a confidence interval (CI) of 95% for PD reduction, CAL gain and BOP. The means of the periodontal clinical parameters were compared between the baseline and post-treatment periods between the test groups and the control groups. The heterogeneity was assessed using the Cochran Q test (Q (df = 3), α = 5%). A total of 67 articles were found, and after the selection process, three randomized controlled trials were included in the meta-analysis. The results indicate that SRP associated with systemic antibiotics promoted additional benefits when compared to SRP alone, with a greater reduction of PD (p = 0.0359, CI = -0.42, -0.01) and a gain of CAL (p = 0.0161, CI = -0.39, -0.04). There was a modest PD reduction (PD, DM -0.21) and a modest CAL gain (CAL, DM -0.22). The results of our meta-analysis reveal the clinical benefits of systemic antibiotics as an adjunct to the non-surgical periodontal treatment of smokers. These clinical improvements, although statistically significant, appeared to be of little clinical relevance.
