RESUMEN
Objective: To examine the therapeutic effects of vitamin E combined with recombinant human epidermal growth factor on recurrent oral ulcers as well as on the levels of serum superoxide dismutase (SOD), interleukin-10 (IL-10), and tumor necrosis factor- (TNF-α), to provide evidence to facilitate medical management. Method: From June 2021 to May 2022, 84 patients with recurrent oral ulcers assessed and treated in our hospital were assigned to the control group and observation group with 42 cases in each group. Vitamin E was administered to the control group, while recombinant human epidermal growth factor and vitamin E were administered to the observation group. The clinical efficacy, serum SOD level, inflammatory factor level (IL-10, TNF-α), immune function index, clinical symptom improvement, pain disappearance time, healing time of ulcer surface, and adverse reactions were examined. Results: Clinical efficacy of the observation group (92.86%) was considerably greater than the control group (73.81%), (P < .05). Following treatment, the observation group had comparatively higher levels of serum SOD and significantly decreased TNF-α and IL-10 concentrations compared to the control group (P < .05). Similarly, post-treatment, the observation group had substantially higher CD3+, CD4+, and CD4+/CD8+ concentrations and lower CD8+ concentrations compared to the normal control (P < .05). In contrast to the control group, the observation group's pain degree score, ulcer diameter, duration for pain relief, and ulcer surface healing time duration were reduced substantially (P < .05). Notably, the incidence of adverse reactions was fairly similar in both groups (P > .05). Conclusion: Vitamin E combined with recombinant human epidermal growth factor has a significant clinical effect on recurrent oral ulcers, can achieve rapid improvement of symptoms in patients, and is relatively safe to be used as a clinical therapy.
