Abstract:
Objective To study the infection of MP-Ab IgM (MP) in serum,bronchial lavage fluid,pleural effusion and cere brospinal from pediatric patients with Mycoplasma Pneumoniae Pneumonia (MPP).Methods From March to June 2013,278 cases of patients suspected MP infection in Children's Hospital Affiliated to Capital Medical University were selected and the MP-Ab IgM of thcire serum,bronchial lavage fluid,pleural effusion and ccrebrospinal fluid specimens were detected with the method of particle agglutination test.Results 181 cases (104 cases of boys,77 cases of girls) of different specimens in (MP) were positive.All the serum samples,278 cases were detected positive serum specimen of 170 cases,the overall detection rate was 61.2％ (170/278),144 cases of bronchial lavage fluid was investigated at the same time,check out the posi rive 62 cases,and the detection rate was 43.1％ (62/144).19 cases for pleural effusion samples at the same time,checked out the positive 13 cases,and detection rate was 68.4％ (13/19).15 cases of cerebrospinal fluid specimens was investigated at the same time,checked out the positive in 1 case,and the detection rate was 6.7％ (1/ 15).Positive rate between different age groups was respectively:6 months～1 year group 29.0％ (9/31),～3 year group 51.0％ (25/49),～5 year group 56.1％ (23/41),～16 year group 79.0％ (124/157),6 months～1 year witb other age groups was statistically significant difference (P＜0.05).In 0.5～1 year,～3 year,～5 year,16 year～four age groups,different types of MP-Ab IgM positive specimens of the same patients,the corresponding results for A:serum type (111 cases) 7,21,13,70.B:serum and bronchoalveolar lavage fluid type (45 cases) 0,2,5,38.C:Serum pleural effusion (7 cases) 0,1,2,4.D:serum and cerebrospinal fluid (1 cases) 0,0,0,1;E:serum and bronchoalveolar lavage fluid and pleural effusion type (6 cases):0,0,2,4.F:bronchoalveolar lavage fluid type (11) 2,1,1,7.Conclusion MP infection varied,have atrend of younger age,and has a tendency to increase year by year,and the patient's infection rates have different characteristics.Positive serum of different age groups was gradually increased with age,infants and young children positive detection rate increased significantlychildren with severe multiple in older children.
