La Yeonju,Kim Yong Chan 대한감염학회 2022 Infection and Chemotherapy Vol.54 No.4
Bone and joint infections (BJI) caused by vancomycin-resistant Enterococcus spp. (VRE) are difficult to treat due to limited antibiotic options. Although linezolid can be used for VRE treatment, it is often discontinued due to time-dependent bone marrow suppression. Daptomycin, a lipopeptide antibiotic agent with rapid bactericidal activity, is another available therapeutic option for VRE infections. We report a case of VRE BJI successfully treated with a high dose of daptomycin plus β-lactam agents. An 84-year-old man received linezolid for the treatment of VRE BJI. After 2 weeks of therapy, the patient experienced bleeding events associated with linezolid-induced bone marrow toxicity and linezolid was discontinued. Next, high-dose daptomycin therapy combined with a β-lactam agent was selected to treat the remaining VRE BJI. During daptomycin treatment, microbiological eradication was achieved, and the patient clinically improved without evidence of adverse events. We highlight the need for daptomycin use for the treatment of VRE infections, especially in cases where linezolid is ineffective.

Background The growth of Candida in respiratory secretions is usually considered colonization, and antifungal therapy is rarely required. The role of Candida colonization in the progression of bacterial pneumonia remains controversial. The aim of this study was to identify the clinical implication of Candida score by analyzinge the relationship with multidrug-resistant (MDR) pneumonia and prognosis in patients with airway Candida colonization. Materials and Methods This study was a retrospective review of patients with airway Candida colonization by bronchial washing or bronchoalveolar lavage. The Candida score was calculated according to the four factors (severe sepsis, surgery at baseline, total parenteral nutrition, and multifocal Candida colonization). Pneumonia related mortality or hopeless discharge expecting death was defined as a poor outcome. Results A total of 148 patients were enrolled in the study. In a multivariate analysis model, Candida score was identified as an independent predictor of poor outcomes (odds ratio 2.23; 95% confidential interval 1.57 – 3.17; P <0.001) in pneumonia patients with airway Candida colonization. With a Candida score of three or higher compared with low score group, it was associated with bacterial pneumonia, especially methicillin-resistant Staphylococcus aureus (MRSA) infection (0.0% vs. 15.2%, P = 0.004). In addition, patients with a high Candida score had a longer hospital stay (13 vs. 38 days, P <0.001), longer duration of intensive care (7 vs. 18 days, P <0.001), and higher pneumonia-related mortality (0.0% vs. 45.5%, P <0.001) as compared to the low Candida score group. The Candida score showed a positive correlation with other pneumonia severity scales such as CURB-65 (Confusion, Urea, Respiratory rate, Blood pressure, and age ≥65 years) (r = 0.461, P <0.001), Pneumonia Severity Index (r = 0.397, P <0.001), and predisposition, insult, response, and organ dysfunction (PIRO) score (r = 0.425, P <0.001). Conclusion This study revealed that Candida is no longer a bystander of airway colonization, and that it affects the progression of bacterial pneumonia, including multidrug-resistant pathogens, particularly MRSA infection. Also Candida score can be used to predict the prognosis of patients with pneumonia.
