ABSTRACT
ObjectiveTo analyze the seroepidemiologic of Mycoplasma pneumoniae infection and evaluate antibiotics medication of some positive patients by follow-up. Methods Serodia-MycolⅡ particle agglutination assay was used to detect serum antibodies against Mycoplasma pneumoniae in 3 134 clinically suspected infections. Mycoplasma pneumoniae infection was determined and seroepidemiologic was analyzed by results of the test, including positive antibody rates in whole subjects, in male or female groups, in different seasons or age groups as well as in different sources. Evaluate antibiotics medication of some positive patients by follow-up. The average days of medication were counted, different antibiotics medication and medication effect were analyzed. Results In 3 134 serum samples from clinically suspected Mycoplasma pneumoniae infections, 350 ( 11.2% ) were tested with positive antibodies. The positive antibody rate in female patients was 12. 3% ( 198/1 604), which was higher than 9. 9% ( 152/1 530) in males (X2 =4. 58,P <0. 05). The peak season was found in the fourth quarter (October-December) with 13.2% of positive antibody and the highest positive rate (32. 8%, 45/137 ) was found in school aged (5 -9 years old )children. Samples from pediatrics clinic and ward were tested to have highest positive rates ( 27. 9% and 26. 5%, respectively ), comparing that from other sources. Infection due to Mycoplasma pneumoniae was identified in 28% (7/25) of community-acquired pneumonia (CAP) patients, which is higher than other diseases. Based on the follow-up of 91 antibody positive patients, between 5 to 120 days ( mean 24. 2 days )were counted from appearance of clinical symptoms to clinic visiting/testing. 71 of 91 (78. 0% ) patients was medicated with macrolide antibiotics, 4 (4. 4% ) with quinolones, 4 (4. 4% ) with cephalosporin, and the rest 12 ( 13.2% ) patients were medicated with other antibiotics or only symptomatic treatment. The average period of antibiotics medication was between 3 to 21 days (mean 8. 2 days). Medication effect results by follow-up were cure in 35 ( 38. 5% ), improvement in 50 (54. 9% ), and poor responses in 6 (6. 6% ).ConclusionsMycoplasma pneumoniae positive rate in female patients was higher than in males, and peak rate was found in the fourth quarter and in school aged children. Samples from pediatrics clinic and ward were tested to have highest positive rates. Physicians could choose first line antibiotics according to laboratory test results of Mycoplasma pneumoniae, and gain good effect.
