Infected diabetic foot ulcers (DFUs) represent a serious threat to public health because of their frequency and the severity of their consequences. DFUs are frequently infected by bacteria in biofilms, obstructing antibiotic action. Antibiofilmogram was developed to assess the impact of antibiotics to inhibit biofilm formation. This pilot study aimed to determine the benefits of this technology in predicting antibiotic activity on the outcome of 28 patients with Grade 2 DFUs that were infected by a monomicrobial . Patients with diabetes were followed during the antibiotic treatment (day 14) and the follow-up period of the study (day 45). The contribution of Antibiofilmogram was compared between patients with non-concordant results ( = 13) between antibiogram and Antibiofilmogram versus concordant results ( = 15). The clinical improvement of wounds (80.0% vs. 38.5%, = 0.0245) and the absence of exudates (0% vs. 33.3%, = 0.0282) were observed in concordant vs. discordant groups. This pilot study provides promising results for the interest of Antibiofilmogram in the prescription of antibiotics to prevent biofilm formation in infected DFUs.
感染性糖尿病足溃疡(DFUs)因其发病频率和后果的严重性,对公众健康构成严重威胁。DFUs常被生物膜中的细菌感染,阻碍抗生素发挥作用。抗生物膜药敏试验被开发用于评估抗生素抑制生物膜形成的效果。这项前瞻性研究旨在确定该技术在预测抗生素对28例由单一微生物感染的2级DFUs患者治疗结果方面的作用。糖尿病患者在抗生素治疗期间(第14天)和研究随访期(第45天)接受随访。对比了药敏试验和抗生物膜药敏试验结果不一致(n = 13)的患者与结果一致(n = 15)的患者中抗生物膜药敏试验的作用。在结果一致组与不一致组中观察到伤口的临床改善情况(80.0%对38.5%,P = 0.0245)和无渗出情况(0%对33.3%,P = 0.0282)。这项前瞻性研究为抗生物膜药敏试验在预防感染性DFUs中生物膜形成的抗生素处方应用方面提供了有前景的结果。
