摘　　要：目的了解鹦鹉热患者的流行病学及临床特征,为早期诊断和防控提供依据。方法收集2023年中国疾病预防控制信息系统报告的北京市大兴区鹦鹉热病例临床资料,回顾性分析患者的一般资料、流行病学特征、临床特征、影像学检查结果、实验室检查结果、治疗和转归情况。结果2023年大兴区共报告7例鹦鹉热病例,均无家庭、工作场所聚集感染;男性4例、女性3例,年龄中位数为66岁,范围为52~82岁。流行病学调查显示,6例患者有明确禽类接触史(4例首次接触鹦鹉或鸽子,2例长期饲养鸽子、鹦鹉或野生鸟),发病时间集中在4、5月。临床症状以高热(6例)、乏力(4例)和畏寒(3例)为主。影像学检查结果显示,6例患者单侧肺出现炎性病变,1例患者累及双肺。实验室检查结果显示,6例患者中性粒细胞百分比升高,2例患者白细胞计数降低,2例患者白细胞计数升高,7例患者C反应蛋白升高。经宏基因组学二代测序技术检测,7例患者均为鹦鹉热衣原体阳性。7例患者均使用喹诺酮类或四环素类抗生素治疗,其中6例痊愈出院、1例死亡。结论鹦鹉热通常以高热、乏力伴单侧肺部炎症为临床表现,患者多有禽类接触史。ObjectiveTo investigate the epidemiological and clinical characteristics of patients with psittacosis,in order to provide a basis for early diagnosis and prevention of the disease.MethodsClinical data of psittacosis cases reported in 2023 from China Disease Prevention and Control Information System in Daxing District,Beijing were collected,and the patients'general information,epidemiological characteristics,clinical characteristics,imaging examination results,laboratory test results,treatment and prognosis were retrospectively analyzed.ResultsA total of 7 cases of psittacosis were reported in Daxing District in 2023,with no clustered infection in households or workplaces.There were 4 males and 3 females,with a median age of 66 years old,and a range of 52 to 82 years old.Epidemiological investigation revealed that 6 patients had a clear history of contact with poultry(4 had first contact with parrots or pigeons,and 2 had long-term exposure to pigeons,parrots or wild birds).The onset time was concentrated in April and May.The primary clinical manifestations included high fever(6 cases),fatigue(4 cases),and chills(3 cases).The imaging examination results showed that inflammatory changes occurred in the unilateral lung of 6 patients,and both lungs were affected in 1 patients.Laboratory test results indicated elevated neutrophill percentage in 6 patients,decreased white blood cell counts in 2 patients,elevated white blood cell counts in 2 patients,and elevated C-reactive protein levels in 7 patients.Metagenomic next-generation sequencing test showed that all seven patients were positive for Chlamydia psittaci.All 7 patients were treated with quinolone or tetracycline antibiotics,with 6 cured and discharged,and 1 died.ConclusionPsittacosis is usually manifested clinically as high fever,fatigue,and unilateral lung inflammation,often associated with poultry exposure.
