Effect of Modified Huading Loulutang on Postoperative Recovery of Chronic Rhinosinusitis with Secretory Otitis Media Due to Toxic Heat Syndromes / 中国实验方剂学杂志

ABSTRACT

Objective:To observe the efficacy of modified Huading Loulutang on postoperative recovery of chronic rhinosinusitis with secretory otitis media due to toxic heat syndromes and the effect of eosinophil cationic protein (ECP), immunoglobulin E (IgE) and intercellular adhesion molecule-1 (ICAM-1) in serum, nasal secretion and otitis media. Method:According to the random number table method, 90 cases were divided into control group and observation group, with 45 cases in each group. All patients were given ceftriaxone sodium + hydroxymezoline after nasal endoscopy. In addition, control group was given Biyuan Tongqiao granule, while observation group was given modified Huading Loulutang for 6 weeks. Lund-Kennedy nasal assessment scale, traditional Chinese medicine symptoms and threshold of hearing at different frequencies were observed in two groups before and after treatment and during 6-week and 18-week follow-up visits. The levels of ECP, IgE and ICAM-1 in serum, nasal and ear secretions were detected before and after treatment. Clinical symptoms, adverse reactions and 12-month recurrence rate were compared. Result:Total control rate was 97.7% (43/44, 95%CI [95.6，98.6]) in observation group, which was higher than 78.6% (33/42, 95%CI [72.4，83.5]) in control group (χ2=6.946, P<0.05). During the 12-month follow-up visit, the recurrence rate was 4.5% (2/44, 95%CI [3.7，5.8]) in observation group, which was lower than 19.0% (8/42, 95%CI[16.8，21.3]) in control group (P<0.05). After treatment, Lund-Kennedy and traditional Chinese medicine symptoms score during 6-week and 18-week follow-up visits in observation group were significantly lower than those in control group (P<0.05). Hearing threshold in observation group at different frequencies was significantly lower than that in control group (P<0.05). ECP, IgE and ICAM-1 levels in serum, nasal and auricular secretions in observation group were significantly lower than those in control group (P<0.05). The incidence of adverse reactions was 6.8% (3/44, 95%CI [5.3，8.1]) in observation group, which was lower than 28.6% (12/42,95%CI [25.3，30.2]) in control group (P<0.05). Conclusion:Modified Huading Loulutang can significantly improve postoperative clinical symptoms of chronic rhinosinusitis and otitis media due to toxic heat syndromes with secretion, with a low recurrence rate and fewer complications.
