摘　　要：目的分析2023年我院呼吸道感染的流行病学特征及血清学指标变化,为呼吸道感染疾病的诊断和治疗提供依据。方法选取2023年1月至2023年12月就诊于北京佑安医院的483例呼吸道病原体IgM阳性者为研究对象,采用间接免疫荧光法检测血清中的肺炎支原体(MP)、肺炎衣原体(CP)、甲型流感病毒(INFA)、副流感病毒(PIV)、呼吸道合胞病毒(RSV)、腺病毒(ADV)、柯萨奇病毒(COX)、嗜肺军团菌(LP)、乙型流感病毒(INFB)9种病原体免疫球蛋白(Ig)M抗体。采用卡方检验对不同性别、年龄、季节患者的血清呼吸道病原体IgM阳性率进行统计分析,采用Kru’skal-Wallis检验分析不同病原体感染者间的血清学指标。结果(1)483例呼吸道感染患者中,单一病原体IgM阳性者占比为39.3%(190/483),>2种病原体IgM阳性者占比为60.7%(293/483)。单一病原体IgM阳性患者中,位居前3位的依次为INFB(39.5%,75/190)、INFA(24.2%,46/190)及MP(20%,38/190);混合病原体IgM阳性患者中,以2种病原体混合感染为主,占比为61.7%(181/293),其中以病原体INFA+INFB为主,占比43.3%(127/293),其次为MP+INFA+INFB,占比17.4%(51/293)。(2)女性患者血清MP、ADV IgM阳性率高于男性,INFB IgM阳性率低于男性,差异均具有统计学意义(P<0.05)。(3)0~18、19~45、46~59、>60岁4个年龄段患者血清MP、COX病原体IgM阳性率比较,差异均有统计学意义(P均<0.05),其中0~18岁MP、COX阳性率分别高于19~45、46~59、>60岁(P均<0.05),19~45岁MP阳性率高于46~59、>60岁(P均<0.05)。(4)春、夏、秋、冬4个季节血清MP、INFA IgM阳性率比较,差异有统计学意义(P<0.05);其中春季MP阳性率高于秋季(P<0.05),冬季阳性率分明高于夏季、秋季(P均<0.05);INFA阳性率冬季高于夏季(P<0.05)。(5)将483例呼吸道感染者分为MP IgM阳性组、病毒IgM阳性组、混合感染组,3组间eGFR、EOS、PLT比较,差异有统计学意义(P<0.05),其中混合感染组中EOS高于MP IgM阳性组(P<0.05),Objective To analyze the epidemiological characteristics and the trend of serological indicator changes of respiratory infections in our hospital in 2023 and to provide a knowledge basis for the diagnosis and treatment of respiratory infectious diseases.Methods A cohort of 483 patients with respiratory tract infections admitted to Beijing You’an Hospital between January,2023 and December,2023,were selected for the study.Indirect immunofluorescence assay was conducted to detect immunoglobulin M(IgM)antibodies to nine respiratory pathogens in serum samples,including Mycoplasma pneumoniae(MP),Chlamydophila pneumoniae(CP),influenza A virus(INFA),parainfluenza virus(PIV),respiratory syncytial virus(RSV),adenovirus(ADV),Coxsackie virus(COX),Legionella pneumophila(LP),and influenza B virus(INFB).Chi-square test was applied to statistically analyze the positive rates of serum respiratory pathogens IgM antibodies in patients of different groups of gender,age,and season,and Kruskal-Wallis test was used to analyze the serological indicators among patients infected with different types of pathogens.Results(1)Among 483 cases of respiratory tract infections,the proportion of single pathogen IgM-positive individuals was 39.3%(190/483),while the proportion of>2 pathogens IgM-positive individuals accounted for 60.7%(293/483).Among single-pathogen IgM-positive patients,the top three pathogens were INFB(39.5%,75/190),INFA(24.2%,46/190),and MP(20%,38/190)in a descending order.Among patients positive for mixed pathogen IgM,dual-pathogen infections were predominant,accounting for 61.7%(181/293),with INFA+INFB being the most common combination,accounting for 43.3%(127/293),followed by MP+INFA+INFB,accounting for 17.4%(51/293).(2)Female patients exhibited higher serum positivity rates for MP and ADV IgM compared to males,while the positivity rate for INFB IgM was lower than that of males,with all differences being statistically significant(P<0.05).(3)When comparing the serum positivity rates of MP and COX pathogens among patients in f
