Efficacy of Fangfeng Tongsheng Granule Combined with Levocetirizine in the Treatment of Chronic Urticaria and Its Effect on Serum Complement, IL-4, IgE, and IFN- Levels in Patients.

OBJECTIVES

To investigate the efficacy of Fangfeng Tongsheng granule combined with levocetirizine in the treatment of chronic urticaria and its effect on serum complement, interleukin (IL)-4, immunoglobulin E (IgE), and interferon- (IFN-) levels in patients.

METHODS

A total of 98 patients with chronic urticaria who were admitted to our hospital from July 2021 to March 2022 were selected and divided into random odd-even numbers. The odd numbers were included in the observation group, with a total of 49 cases, and they were treated with Fangfeng Tongsheng granule combined with levocetirizine; the even numbers were included in the control group, with a total of 49 cases and were treated with levocetirizine alone. The two groups of patients were treated continuously for 4 weeks, and the clinical efficacy of the two groups was observed. Before treatment, 2 weeks and 4 weeks after treatment, evaluate the clinical symptom scores of patients such as itching, flushing, wheal, edema, observe the improvement of clinical symptoms of patients, and the changes in Dermatology Life Quality Index (DLQI). Serum complement C3, C4, T lymphocyte subsets CD , CD , CD levels and CD /CD ratio, IL-4, IgE, and IFN- levels and the occurrence of adverse reactions in the two groups were calculated and observed. All patients were followed up for 2 months after treatment to observe the recurrence of patients.

RESULTS

The scores of clinical symptoms such as wheal, itching, flushing, edema, and attack frequency in the observation group at each time point after treatment were lower than those in the control group ( times were 725.365, 851.521, 936.411, 3943.136, and 2226.147, all < 0.05 ( between-group were 40.642, 102.124, 188.523, 259.291, and 23.92, < 0.05); the total effective rate of the observation group was 93.88% (46/49), which was significantly higher than that of the control group, 73.47% (36/49) (  = 7.470, =0.006). The DLQI scores of the observation group at each time point after treatment were lower than those of the control group ( time was 282.214, < 0.05; between-group was 6.546, < 0.05). There was no significant difference in serum C4 levels between the two groups at each time point ( time was 1.225, > 0.05; between-group was 0.408, > 0.05); serum complement C3, CD , and CD /the ratio of CD and IFN- were higher than those in the control group ( time was 407.352, 107.823, 32.941, and 2354.147, < 0.05; between-group was 40.941, 24.710, 54.982, and 264.921, < 0.05); the observation group at each time after treatment the levels of IgE and IL-4 were lower than those of the control group ( time were 373.124 and 395.612, < 0.05; between-group were 21.802 and 62.591, < 0.05). The incidence of adverse reactions in the observation group was 12.24% (6/49) compared with 10.20% (5/49) in the control group, which had no significant difference (  = 0.102, =0.749). Both groups were followed up for 2 months after treatment. The recurrence rate in the observation group was 12.24% (6/49), which was lower than that in the control group, which was 32.65% (16/49) (  = 5.861, =0.015).

CONCLUSION

The application of Fangfeng Tongsheng granules combined with levocetirizine in patients with chronic urticaria can effectively improve the clinical symptoms of patients, improve clinical efficacy, reduce the impact of the disease on life, improve the immune status of patients, and reduce the risk of recurrence.
