  •   Objective  To explore the efficacy and safety of doxycycline in treating pertussis in children aged 8 years and above.  Methods  A retrospective analysis was conducted on 166 children aged ≥ 8 years with pertussis who attended the pediatric outpatient department of Zhejiang Hospital of Integrated Traditional Chinese and Western Medicine from December 2023 to May 2024. According to the antibiotics selected, patients were divided into the azithromycin group (62 cases), the trimethoprim sulfamethoxazole (TMP-SMZ) group (48 cases), and the doxycycline group (56 cases). The clinical efficacy, time to symptom relief, and incidence of adverse reactions were compared among the three groups.  Results  The azithromycin group showed 9 cases of significant effectiveness, 11 cases of effectiveness, and 42 cases of ineffectiveness, with a total effective rate of 32.25%. The TMP-SMZ group demonstrated 14 cases of significant effectiveness, 26 cases of effectiveness, and 8 cases of ineffectiveness, yielding a total effective rate of 83.33%. In the doxycycline group, 18 cases were significantly effective, 26 cases were effective, and 12 cases were ineffective, with a total effective rate of 78.57%. The total effective rate of the azithromycin group was lower than that of the other two groups (P < 0.001 after Bonferroni correction). The times to symptom relief time in the azithromycin, TMP-SMZ, and doxycycline groups were (13.05±4.23) days, (11.00±2.30) days, and (11.23±2.59) days, respectively, with the azithromycin group showing a significantly longer duration (P < 0.05). In terms of adverse reactions, 11 cases in the azithromycin group and 5 cases in the doxycycline group had gastrointestinal symptoms. In the TMP-SMZ group, 14 patients developed adverse reactions, including 4 with gastrointestinal symptoms and 10 with rashes. The TMP-SMZ group had higher incidences of rash and total adverse reactions compared to the doxycycline group (P < 0.017 after Bonferroni correction).  Conclusion  Doxycycline can effectively alleviate symptoms in children aged 8 years and older with pertussis, with fewer adverse reactions, supporting its clinical application value.
