Abstract:
Objective: To understand the infection status of mycoplasma pneumonia in 1-3-month children with spastic cough and analyse effect of macrolide drugs on spastic cough.
Methods: A total of 235 cases of whooping cough syndrome in children were hospitalized for treatment from January 2015 to August 2016 in Zhengzhou Children's Hospital to different pathogens: Mycoplasma pneumoniae infection group(A，33 cases), non-Mycoplasma pneumoniae infection group(B,103 cases) and unknown pathogen group(C,99 cases). Direct immunofluorescence assay was used to detect the 7 common respiratory pathogenic antibodies. ELISA was performed to determine the titer of Mycoplasma pneumoniae antibodies in the serum at acute stage and recovery stage. Blood Agar was used to perform sputum bacteria culture. The children in group A and B were given cephalosporin and macrolides antibiotics, while those in group C were given cephalosporins, the treatment lasting 7 days. Observe the time for the spasmodic cough to disappear and the clinical effect in the children who came to hospital within 7 days of disease onset and after 7 days.
Results: The pathogens of whooping cough syndrome were mostly viruses and bacteria; the detection rate of Mycoplasma pneumoniae was 14.04%(33/235).The spasmodic cough lasted for (5.79±0.89) days in the children visiting hospital within 7 days and their average hospital stay was (10.25±1.66) days, both of which were lower than the children who visited hospital for treatment 7 days after disease onset ［(10.38±2.00) days,(13.75±1.49) days］, and the difference being significant(P<0.05). The total effective rate in the 3 groups was respectively 93.94%(31/33), 91.26%(94/103) and 79.80%(79/99), and there was statistical difference(P<0.05).
Conclusion: The pathogens of whooping cough syndrome are mostly viruses and bacteria. It can shorten the time of spasmodic cough and average hospital stay to visit hospital early, make early diagnosis and perform effective treatment. Cephalosporins are very effective in the treatment of whooping cough syndrome in small babies, but their abuse should be avoided.
