The incidence of skin and soft tissue infections (SSTI) due to multi-drug resistant pathogens is increasing. The concomitant increase in antibiotic use along with the ease with which organisms develop mechanisms of resistance have together become a medical crisis, underscoring the importance of developing innovative and effective antimicrobial strategies. Nitric oxide (NO) is an endogenously produced molecule with many physiologic functions, including broad spectrum antimicrobial activity and immunomodulatory properties. The risk of resistance to NO is minimized because NO has multiple mechanisms of antimicrobial action. NO's clinical utility has been limited largely because it is highly reactive and lacks appropriate vehicles for storage and delivery. To harness NO's antimicrobial potential, a variety exogenous NO delivery platforms have been developed and evaluated, yet limitations preclude their use in the clinical setting. Nanotechnology represents a paradigm through which these limitations can be overcome, allowing for the encapsulation, controlled release, and focused delivery of NO for the treatment of SSTI.
由于多药耐药病原体导致的皮肤和软组织感染(SSTI)的发病率正在上升。抗生素的使用同时增加,而生物体产生耐药机制的容易程度也随之增加,这一起构成了一场医学危机,强调了开发创新和有效的抗菌策略的重要性。一氧化氮(NO)是一种内源性产生的分子,具有许多生理功能,包括广谱抗菌活性和免疫调节特性。由于 NO 具有多种抗菌作用机制,因此对其产生耐药性的风险最小化。NO 的临床应用受到限制,主要是因为它具有高度反应性,并且缺乏适当的储存和输送载体。为了利用 NO 的抗菌潜力,已经开发和评估了多种外源性 NO 输送平台,但这些平台的局限性使其无法在临床环境中使用。纳米技术代表了一种可以克服这些限制的范例,允许对 NO 进行封装、控制释放和集中输送,以治疗 SSTI。
