Abstract

Purpose: To investigate the curative effect of levocetirizine hydrochloride tablets on chronic urticaria as well as its mediating effect on serum levels of total IgE and inflammatory factors.

Methods: Ninety-two (92) patients with chronic urticaria, were randomly divided into control group (CG) and study group (SG). Patients in CG were treated with oral administration of desloratadine citrate tablets while SG patients received oral levocetirizine hydrochloride tablets. A comparative analysis was conducted between the two patient cohorts encompassing clinical therapeutic outcomes, symptom scoring, T lymphoid subset cell levels, serum total IgE concentrations, serum inflammatory factor levels, as well as adverse reactions.

Results: Total treatment effectiveness was higher in SG (97.83 %) than in CG (82.61 %; p < 0.05). After treatment, wheal duration, size and number as well as pruritus scores were markedly lower in SG than in CG, albeit non-significantly (p > 0.05). The levels of CD3+ CD4+, and CD4+/CD8+ ratio in SG after treatment were significantly higher than those in CG (p < 0.05). Furthermore, the serum IgE, IL-4 and IL-13 levels were significantly lower in SG than in CG, while the IFN-γ level was significantly higher (p < 0.05).

Conclusion: Levocetirizine hydrochloride tablets produce a significant clinical curative effect on chronic urticaria relative to desloratadine citrate tablets. It reduces the levels of inflammatory factors and mitigates immune dysfunction in patients by increasing the serum level of total IgE. Therefore, it is a potential candidate for further clinical investigations on a larger and more diverse population.
