摘要 BACKGROUND The onset symptoms of people infected by Chlamydia psittaci can mimic the coronavirus disease 2019(COVID-19).However,the differences in laboratory tests and imaging features between psittacosis and COVID-19 remain unknown.AIM To better understand the two diseases and then make an early diagnosis and treatment.METHODS Six patients from two institutions confirmed as psittacosis by high-throughput genetic testing and 31 patients confirmed as COVID-19 were retrospectively included.The epidemiology,clinical characteristics,laboratory tests and computed tomography(CT)imaging features were collected and compared between the two groups.The follow-up CT imaging findings of patients with psittacosis were also investigated.RESULTS The white blood cell count(WBC),neutrophil count and calcium were more likely to be decreased in patients with COVID-19 but were increased in patients with psittacosis(all P=0.000).Lymphocyte count and platelet count were higher in patients with psittacosis than in those with COVID-19(P=0.044,P=0.035,respectively).Lesions in patients with psittacosis were more likely to be unilateral(P=0.001),involve fewer lung lobes(P=0.006)and have pleural effusions(P=0.002).Vascular enlargement was more common in patients with COVID-19(P=0.003).Consolidation in lung CT images was absorbed in all 6 patients.CONCLUSION Psittacosis has the potential for human-to-human transmission.Patients with psittacosis present increased WBC count and neutrophil count and have specific CT imaging findings,including unilateral distribution,less involvement of lung lobes and pleural effusions,which might help us to differentiate it from COVID-19.
