摘要:
目的 探讨呼吸道合胞病毒(RSV)、流感病毒(IV)、腺病毒(AD)及肺炎支原体(MP)感染所致的肺炎患儿支气管肺泡灌洗液(BALF)中肺表面活性物质相关蛋白(SP)的表达及其临床意义。方法 选择2015年1月至2016年12月驻马店市第一人民医院收治的肺炎患儿39例,所有患儿入院后第2天晨起空腹状态下抽取肘静脉血 4 mL,采用酶联免疫吸附试验(ELISA)检测RSV、IV、AD和MP的IgM抗体,明确患儿罹患肺炎的病原体;患儿均行纤维支气管镜检查取BALF,采用ELISA检测BALF中SP-A、SP-B、SP-C、SP-D水平。结果 39例患儿中,RSV感染14例(RSV组),IV感染9例(IV组),AD感染5例(AD组),MP感染11例(MP组)。RSV组、IV组和AD组患儿BALF中SP-A、SP-B、SP-C及SP-D水平显著高于MP组(P<0.05),但RSV组、IV组及AD组患儿BALF中SP-A、SP-B、SP-C、SP-D水平比较差异均无统计学意义(P>0.05)。结论 RSV、IV、AD及MP感染所致的肺炎患儿的肺泡上皮均有损伤,其中MP感染所致的肺泡上皮损伤更为严重;检测肺炎患儿BALF中SP水平有助于临床医师准确判断患儿肺泡上皮损伤程度和呼吸功能。
Abstract:
Objective To explore the clinical significance of the expression of pulmonary surfactant associated protein(SP) in bronchoalveolar lavage fluid(BALF) of children with pneumonia caused by respiratory syncytial viruses(RSV),influenza viruses(IV),adenovirus(AD) and mycoplasma pneumoniae(MP).Methods Thirty-nine children with pneumoniawere selected from January 2015 to December 2016 in the First People′s Hospital of Zhumadian City.The ulnar venous blood 4 mL of all children was collected at the morning of the second day after hospitalization;the IgM antibody of RSV,IV,AD and MP were detected by enzyme linked immunosorbent assay,so as to identify the pneumonic pathogens.All children were examined by fiberoptic bronchoscopy,and the BALFs were collected.The levels of SP-A,SP-B,SP-C and SP-D in BALF were detected by ELISA.Results In the 39 cases,there were 14 cases of RSV infection (RSV group),9 cases of IV infection (IV group),5 cases of AD infection (AD group),11 cases of MP infection (MP group).The levels of SP-A,SP-B,SP-C and SP-D in BALF in RSV group,IV group and AD group were significantly higher than those in MP group (P<0.05).However,there was no significant difference in the levels of SP-A,SP-B,SP-C and SP-D in BALF among the RSV group,IV group and AD group(P>0.05).Conclusion There is alveolar epithelial injury in children with pneumonia caused by RSV,IV,AD and MP;and the alveolar epithelial injury caused by MP infection is more serious.Detecting SP level in BALF in children with pneumonia is helpful to accurately determine the degree of alveolar epithelial injury and respiratory function.
