Abstract

Background: Legionella maceachernii pneumonia is a severe respiratory infection with low incidence but high mortality. However, the optimal treatment for this disease remains unclear. We report a case of successful treatment of Legionella maceachernii pneumonia, which is the first report of such a case in China.

Case presentation: An 87-year-old man with concomitant chronic obstructive pulmonary disease, liver cirrhosis, and history of left nephrectomy was diagnosed with Legionella maceachernii pneumonia using Dano-seq pathogen metagenomic testing. After two weeks of treatment with cefoperazone/sulbactam combined with quinolone antibiotics, the patient showed improvement and was discharged. The patient continued to take oral quinolone antibiotics for one week after discharge and recovered during outpatient follow-up.

Conclusions: Dano-seq pathogen metagenomic testing can rapidly diagnose Legionella maceachernii pneumonia, and taking quinolone antibiotics is an effective treatment.

军团菌麦氏肺炎:病例报告和文献综述。
背景:军团菌肺炎是一种发病率低但死亡率高的严重呼吸道感染。然而,该病的最佳治疗方法仍不明确。我们报告了一例成功治疗军团菌肺炎的病例,这在中国尚属首例:病例介绍:一名87岁的男性患者同时患有慢性阻塞性肺病、肝硬化和左肾切除术史,通过Dano-seq病原体元基因组检测被确诊为军团菌肺炎。在接受头孢哌酮/舒巴坦联合喹诺酮类抗生素治疗两周后,患者病情好转并出院。患者出院后继续口服喹诺酮类抗生素一周,在门诊随访期间痊愈:结论:Dano-seq病原体元基因组检测可快速诊断军团菌肺炎,服用喹诺酮类抗生素是一种有效的治疗方法。
