Am J Resp Crit Care:阿奇霉素治疗囊性纤维化早期假单胞菌感染疗效分析!

由此可见,阿奇霉素与PEx风险显著降低和体重持续改善相关,但对早期Pa患儿微生物学结局无影响。

通常用吸入型抗假单胞菌抗生素如妥布霉素吸入溶液(TIS)处理铜绿假单胞菌(Pa)的新分离物。通过降低肺部恶化(PEx)和炎症的风险来补充传统抗微生物的治疗方法可能最终延长Pa复发的时间。近日,呼吸内科以及重症医学领域权威杂志Am J Resp Crit Care上发表了一篇研究文章,为了验证这样一个假设,即在CF和早期Pa患儿中添加阿奇霉素至TIS中可降低PEx的风险并延长了Pa复发的时间。

OPTIMIZE试验是一项多中心、双盲、随机、安慰剂对照、为期18个月的在6月至18岁CF和早期Pa患儿中进行的试验。给予阿奇霉素或安慰剂每周3次,添加到标准化的TIS中。该研究的主要终点是PEx需要抗生素治疗的时间,次要终点为Pa复发的时间,以及其他临床和安全性结果。

221名参与者(111名接受安慰剂,110名接受阿奇霉素)被纳入研究。因为该试验已达到预先设定的临床疗效边界而停止招募。与安慰剂相比,阿奇霉素组的PEx风险降低了44%(风险比[HR]:0.56,95%CI:0.37-0.83,p=0.004)。与安慰剂相比,阿奇霉素组体重增加1.27kg(95%CI:0.01-2.52,p=0.046)。微生物学、临床或安全性终点没有显著差异。

由此可见,阿奇霉素与PEx风险显著降低和体重持续改善相关,但对早期Pa患儿微生物学结局无影响。

雅司病是在至少 14 个热带地区国家儿童慢性毁容性溃疡的根本病因。WHO 新采用的雅司病根除策略使用单轮阿奇霉素集体治疗,然后进行靶向治疗方案,来自试点研究的数据表明雅司病短期内显著减少。我们评估了 WHO 雅司病根除策略的长期效果

警惕!阿奇霉素配伍禁忌和相互作用

阿奇霉素对革兰阴性菌的抗菌活性是红霉素的2~8倍(抗革兰阳性菌的活性比红霉素略差),对肺炎支原体的作用是大环内酯类中的最强者。阿奇霉素的组织浓度较同期血药浓度高出10~100倍,炎症部位浓度比非炎症部位高达6倍以上。阿奇霉素血浆半衰期35~48h,患者口服用药依从性好。

Am J Epidemiol:用阿奇霉素治疗沙眼与衣原体ompA多样性之间的关系

加利福尼亚大学旧金山分校的Chin SA近日在Am J Epidemiol发表了一篇文章,他们对大规模使用阿奇霉素导致衣原体遗传多样性降低,并有可能再次导致感染复发的假设进行研究,最终认为其证据不支持ompA多样性与眼睛衣原体传播有关。

警惕!阿奇霉素可引发致命性心律失常!

阿奇霉素是第二代大环内酯类抗生素,抗菌谱广,应用广泛,如小儿急性支气管炎、肺炎、沙眼、伤寒、疟疾、中耳炎、皮肤和软组织感染和社区获得性肺炎等等,具有高有效率和清除率特点。但是,随着阿奇霉素临床日趋广泛,其不良反应也日趋增多,其中部分不良反应甚至是致命的!

头孢菌素+阿奇霉素,究竟合不合理?

传统理论认为:β-内酰胺类抗生素是繁殖期杀菌药,能和静止期杀菌药物氨基糖苷类联用,但不宜与快速抑菌药如大环内酯类抗菌药物联用,两者联用会减弱β-内酰胺类抗菌药物的杀菌效果。但是,近年来大量实验研究及临床实践证明:两类药物联用并无拮抗作用,会产生协同互补的效果。
