采用改良双向琼脂扩散法,32例过敏性哮喘血清中有15例可检得细菌抗体,其中肺炎球菌的阳性率为31.25％,流感杆菌为18.75％,42例正常人仅6例阳性,肺炎球菌和流感杆菌均呈阴性。 细菌抗体检出率与能敏感反映炎症的血清C反应蛋白(CRP)值有关。13例CRP增高的过敏性哮喘中有11例可检得细菌抗体,表明细菌感染同样在过敏性哮喘中起一定作用。 The modified two-dimensional agar diffusion method, 32 cases of allergic asthma sera can be detected in 15 cases of bacterial antibodies, including pneumococcal positive rate was 31.25%, influenza bacilli was 18.75%, 42 cases of normal only 6 cases of positive, pneumococcal And influenza bacilli were negative. The detection rate of bacterial antibodies is related to the serum C-reactive protein (CRP) value that can reflect the inflammation sensitively. Eleven of the 13 cases of allergic asthma with elevated CRP were screened for bacterial antibodies, suggesting that bacterial infection also plays a role in allergic asthma.
