摘要: 目的

探讨鹦鹉热衣原体肺炎患者的临床特点以及具有家禽类接触史的患者尽早进行宏基因二代测序(metagenomics next-generati sequencing,mNGS)在早期诊断中的重要性。

方法

收集2020年11月—2021年1月新泰市第三人民医院收治的10例鹦鹉热衣原体肺炎患者的临床资料。回顾性分析患者的临床表现、各项实验室检查结果、肺部影像学结果、mNGS病原学结果及治疗转归。

结果

10例患者中有9例为当地肉食鸭加工厂工人,1例发病前曾接触过鹦鹉。临床表现主要为发热、咳嗽、乏力、肌肉酸痛。8例患者白细胞计数轻度升高,中性粒细胞比例、C反应蛋白(C reactive protein,CRP)10例患者均升高;9例患者血沉(erythrocyte sedimentation rate,ESR)升高;5例患者降钙素原(procaicltonin,PCT)升高;D-二聚体除2例患者正常外其余8例不同程度升高;3例患者出现谷草转氨酶(aspartate aminotransferase,AST)、谷丙转氨酶(Alanine aminotransferase,ALT)轻度升高;4例患者心肌酶异常,主要为肌酸激酶(creatine kinase,CK)和乳酸脱氢酶(lactate dehydrogenase,LDH)轻度升高。胸部CT检查9例患者为单侧肺段或肺叶实变,1例患者为双侧肺叶斑片状实变影,其中2例患者有少量胸腔积液。10例患者均未出现肾功能受损。10例患者均行mNGS检测,检出鹦鹉热衣原体核酸序列,确诊后给予多西环素联合莫西沙星治疗,均治愈。

结论

鹦鹉热衣原体肺炎发病率低,临床医生重视不足,但在接触禽类养殖和加工人群中若发生短期聚集性发热、咳嗽等症状,需提高警惕,在发病初期对疑似病例应尽早行mNGS检测,避免误诊漏诊。

Abstract: Objective

To investigate the clinical characteristics of patients with chlamydia psittaci pneumonia, the contact history of poultry and the importance of early metagenomics next-generati sequencing (mNGS) in early diagnosis.

Methods

The clinical data of 10 patients with Chlamydia psittaci pneumonia treated in Xintai Third People's Hospital from November 2020 to January 2021 were collected. The clinical manifestations, laboratory examination characteristics, pulmonary imaging characteristics, etiological results and treatment outcome of mngs were analyzed retrospectively.

Results

Among the 10 cases, 9 cases were workers of local meat duck processing factory, and 1 case had been exposed to parrots before onset. The main clinical manifestations were fever, cough, fatigue and muscle soreness; The white blood cell count increased slightly in 8 patients, the proportion of neutrophils and C-reactive protein (CRP) all increased, and the erythrocyte sedimentation rate (ESR) increased in 9 patients. Procalcitonin (PCT) was elevated in 5 cases. D-dimer was elevated in 8 cases except 2 normal cases.Liver transaminase (AST, ALT) was slightly elevated in 3 cases, and myocardial enzyme was abnormal in 4 cases, mainly CK and LDH were slightly elevated. Chest CT showed unilateral consolidation of lung segments or lobes in 9 cases, patchy consolidation of bilateral lobes in 1 case, and a small amount of pleural effusion in 2 cases. None of the 10 patients had impaired renal function. All 10 patients were tested by mNGS, and the nucleic acid sequence of Chlamydia psittaci was detected. After diagnosis, they were treated with doxycycline combined with moxifloxacin, and all were cured.

Conclusion

The incidence rate of chlamydia psittaci pneumonia is low, and clinicians do not pay enough attention to it. However, in case of short-term aggregated fever, cough and other symptoms in the people who contact with poultry breeding and processing, they should be vigilant. In the early stage of the disease, the suspected cases should be tested as early as possible to avoid misdiagnosis and missed diagnosis.
