ABSTRACT
Objective:To investigate the diagnosis and clinical characteristics of five elderly patients with Chlamydia psittaci-caused severe pneumonia.Methods:Through retrospective analysis, diagnosis and treatment process and clinical characteristics of five elderly inpatients with severe pneumonia caused by Chlamydia psittaci were summarized in the Department of Critical Care Medicine, Quanzhou First Hospital East Street Branch Area, affiliated to Fujian Medical University between January to June 2021.Results:Five patients with severe pneumonia caused by Chlamydia psittaci were aged from 64 to 74 years, with various underlying diseases such as coronary heart disease, chronic heart failure, chronic obstructive pulmonary disease, etc.All patients had an established history of poultry exposure.These cases had high fever, cough, spitting, and dyspnea as the main clinical manifestations.Some of them also had systemic symptoms or weakness of the limbs as the prodromal symptoms.The disease progressed rapidly, with severe respiratory failure, acute kidney injury, and shock appearing soon, accompanied by different degrees of muscle injury, and damage to the heart, liver, blood coagulation, and immune systems at the same time.Laboratory examination showed that levels of inflammatory indicators were increased: at 3, 5, 7 d after admission, the level of C reactive protein was 214.6(153.9-256.3)mg/L, 199.2(115.8-333.8)mg/L, 151.0(11.19-173.7)mg/L, respectively; and interleukin 6 level was 1 241.0(912.1-6822.0)ng/L, 779.1(451.2-7122.0)ng/L, 631.2(7.0-4 321.0)ng/L, respectively.And monitoring results of nutritional index indicated a high metabolic state.The imaging examinations showed that consolidation and ground-glass shadows spreaded to both lungs, may accompany the miliary and nodular shadows, and may also involve pleural which caused pleural effusion.After the clinical use of metagenomic next-generation sequencing(mNGS), mNGS has been confirmed as an important method for the diagnosis of Chlamydia psittaci infection.The disease course and prognosis were related to the severity of the disease, advanced age, underlying diseases, and timely diagnosis and effective treatment.Conclusions:The progression of Chlamydia psittaci pneumonia to severe disease may be related to advanced age, more basic diseases such as chronic cardiopulmonary disease, smoking, and timely diagnosis and treatment.Generally, laboratory and imaging examinations have no diagnostic specificity, but mNGS is of great significance for early diagnosis, transition to target treatment and improvement of prognosis.
ABSTRACT
OBJECTIVE To discuss the necessity of physical examination and laboratory diagnosis before operation of patients with anorectal diseases,and analyze the occupational harm of the staff.METHODS The results of physical examination and laboratory diagnosis before operation in 320 cases were reviewed,and summerized the various kinds of infectious diseases.RESULTS Forty-eight(15.00%) cases accompanied with variety classes of infectious diseases,and 39(12.19%)cases of them accompanied with transfusion-transmitted disease.CONCLUSIONS It is important to think highly of the current situation of anorectal diseases accompanied with infectious diseases,evaluate reasonably the occupational diagnosis to avoid occupational harm.
