One of the most pressing emerging issues in bacterial resistance is multidrug-resistant Klebsiella pneumoniae. The treatment of K. pneumoniae infections is often problematic because of the lack of available therapeutic options, leading to negative effects on morbidity, mortality, and healthcare-associated costs. Carrimycin is a macrolide antibiotic with good antibacterial effects. In this study, we report a patient diagnosed with multidrug-resistant K. pneumoniae infection who was treated with carrimycin. The patient presented with cough, expectoration, dyspnea, and severe hypoxemia requiring noninvasive ventilation. We successively used a variety of antibiotics, including meropenem, tigecycline, and polymyxin, with unsatisfactory results. Finally, we used carrimycin, and the patient's condition improved, resulting in hospital discharge. Therefore, for patients with multidrug-resistant K. pneumoniae infection that does not respond to conventional anti-infective treatments, carrimycin can be considered a treatment option.
