不同呼吸道病原谱抗体IgM检测方法在呼吸道感染诊断中的应用价值比较李民① 【摘要】 目的:比较不同呼吸道病原谱抗体免疫球蛋白M(IgM)检测方法在呼吸道感染诊断中的应用价值。
方法:选取2020年1月—2022年12月于济南市第三人民医院住院的明确诊断为呼吸道感染的500例患者作为研究对象,采集血清,分别用间接免疫荧光法(IFA)、酶联免疫吸附法(ELISA)检测呼吸道合胞病毒-IgM抗体(RSV-IgM)、腺病毒-IgM 抗体(ADV-IgM)、甲型流感病毒-IgM抗体(IFZA-IgM)﹑乙型流感病毒-IgM抗体(IFZB-IgM)、副流感病毒-IgM抗体(HPIVs-IgM)、嗜肺军团菌-IgM抗体(LP-IgM)﹑肺炎衣原体-IgM抗体(CP-IgM)﹑肺炎支原体-IgM抗体(MP-IgM)。
以直接免疫荧光法(DFA)结果为金标准,比较IFA、ELISA检测上述指标的符合率,比较IFA和ELISA对不同标本采集时间病原体IgM抗体检测的符合率。
比较IFA和ELISA对不同疾病类型患者病原体IgM抗体检测的符合率。
结果:以DFA 结果为金标准,IFA检测CP-IgM、MP-IgM阳性符合率高于ELISA,差异有统计学意义(P<0.05)。
IFA、ELISA在7~14 d、15~21 d、>21 d的阳性符合率明显高于<7 d,差异有统计学意义(P<0.05)。
IFA检测支气管炎的阳性符合率高于咽峡炎,毛细支气管炎阳性符合率高于咽峡炎,差异有统计学意义(P<0.05);ELISA检测支气管炎的阳性符合率高于肺炎、咽峡炎,差异有统计学意义(P<0.05)。
结论:IFA与ELISA均可快速检测血清lgM抗体,明确感染源,对指导治疗有积极的意义,有较高的价值。
但检测结果受发病时间、疾病类型的影响,应引起重视。

Method: A total of 500 patients who were hospitalized at Jinan Third People's Hospital from January 2020 to December 2022 and were diagnosed with respiratory tract infections were selected as the research subjects. Serum samples were collected, indirect immunofluorescence assay (IFA) and enzyme-linked immunosorbent assay (ELISA) were used to detect respiratory syncytial virus-IgM antibodies (RSV-IgM), adenovirus-IgM antibodies (ADV-IgM), influenza A virus-IgM antibodies (IFZA-IgM), influenza B virus-IgM antibodies (IFZB-IgM), parainfluenza virus-IgM antibodies (HPIVs-IgM), legionella pneumophila-IgM antibodies (LP-IgM), chlamydia pneumoniae-IgM antibodies (CP-IgM), and mycoplasma pneumoniae-IgM antibodies (MP-IgM). Using direct immunofluorescence assay (DFA) results as the gold standard, IFA and ELISA were used to compare the coincidence rates of the above indicators, and IFA and ELISA were used to compare the coincidence rates of pathogen IgM antibody detection in different specimen collection times. The coincidence rate of IFA and ELISA for detection of pathogen IgM antibody in patients with different disease types was compared. Result: Using DFA results as the gold standard, the positive coincidence rate of CP-IgM and MP-IgM detected by IFA were higher than those by ELISA, and the differences were statistically significant (P<0.05). The positive coincidence rate of IFA and ELISA at 7-14 d, 15-21 d and >21 d were significantly higher than those at <7 d, and the differences were statistically significant (P<0.05). The positive coincidence rate of IFA in detecting bronchitis was higher than that of angina, and the positive coincidence rate of bronchiolitis was higher than that of angina, the differences were statistically significant (P<0.05). The positive coincidence rate of ELISA for bronchitis was higher than that for pneumonia and angina, and the difference was statistically significant (P<0.05). Conclusion: Both IFA and ELISA can quickly detect serum lgM antibody and identify the source of infection, which has positive significance for guiding treatment and has high value. However, the test results are affected by the time of onset and the type of disease, and should be paid attention to.

小儿呼吸道肺炎支原体感染病原体检测的观察【摘要】小儿呼吸道肺炎是儿童常见的呼吸道传染病,呼吸道支原体感染是其中一种常见病原体。
支原体感染导致的肺炎症状轻重不一,容易被忽视。
病原体检测是确诊支原体感染的关键方法,能够及早发现病情并进行精准治疗,减少疾病传播风险。
本文将探讨支原体感染的临床表现、传播途径、诊断和治疗方法,以及影响病原体检测结果的因素。
结合病原体检测在小儿呼吸道肺炎中的作用进行讨论,探讨未来研究方向和临床应用前景。
通过深入了解支原体感染和病原体检测,可以提高对小儿呼吸道肺炎的认识,并为预防和治疗提供更为准确和有效的方法。

支原体感染是小儿呼吸道肺炎中的常见病原体之一。
支原体是一种微小的细菌,可以感染呼吸道、生殖道等部位,引起相应的临床症状。
儿童感染支原体后,常出现发热、咳嗽、喉痛、流涕等症状,严重时还可能导致肺炎等严重并发症。
支原体感染的传播途径主要包括空气传播和接触传播,儿童在集体环境中易受到感染。
及早的支原体检测对指导临床治疗和控制疫情具有重要意义。
对小儿呼吸道肺炎患儿进行支原体病原体检测是非常必要的,有助于及时诊断、治疗和预防该感染病。
支原体感染的检测方法有多种,包括PCR检测、抗原检测、血清学检测等,但检测结果可能受到多种因素的影响。
对病原体检测结果进行分析和解读时,需要考虑这些因素的影响。
1.2 病原体检测的重要性病原体检测在小儿呼吸道肺炎中扮演着重要的角色。
通过及时、准确地检测病原体,可以帮助医生明确疾病的病因,从而有针对性地制定治疗方案。
尤其对于支原体感染这类病原体不易被传统方法检测出的疾病来说,病原体检测更显得尤为重要。
支原体感染在小儿呼吸道肺炎中的发病率较高,而且症状多样且无特异性,容易与其他疾病混淆,因此确诊支原体感染对于治疗和预防疾病的传播至关重要。
