Clinical Evaluation and Therapeutic Effects of Combination Treatment with Mecobalamin + Vitamin E in Recurrent Oral Ulcer

Abstract

PurposeRecurrent oral ulcer is one of the most prevalent inflammatory ulcerative disorders of the oral mucosa. Due to the indeterminant cause and unpredictable course of the disease, clinical treatment of patients with recurrent oral ulcer is focused on relieving the pain, shortening the course of the disease, and prolonging the intermission period. Numerous chemical and biologic agents have been characterized as beneficial in the treatment of patients with recurrent oral ulcer, but there is currently no definitive therapy available. This study aimed to investigate the clinical effects and tolerability of combined mecobalamin tablets and vitamin E capsules in the treatment of recurrent oral ulcer. MethodsA total of 58 patients with recurrent oral ulcer admitted to our hospital were allocated to receive mecobalamin tablets + vitamin E soft capsules (test group) or Fe complex enzyme gargle only (control group) (n = 29 per group). Changes in parameters such as pain level, as measured on a 10-point visual analog scale (VAS); ulcer status and number of ulcers; proinflammatory cytokine levels; and quality of life, as measured using SF-36, from before to after treatment were measured. Mean intermission time and mean ulcer healing time were calculated. Total effectiveness rate was also calculated. The occurrences of adverse reactions in the two groups were quantified. FindingsThe total intermission time interval was significantly longer, the mean ulcer healing time was considerably shorter, the total number of ulcers was appreciably less, and the total effectiveness rate was significantly greater in the test group compared to the control group (all, P < 0.05). The VAS scores were significantly greater after treatment than before treatment in both the test and control groups (mecobalamin + vitamin E, 2.16 [1.09] vs 7.87 [0.51]; control, 3.72 [1.15] vs 7.94 [0.56]; both, P < 0.05). Interleukin (IL)-8, tumor necrosis factor α, and C-reactive protein levels were appreciably down-regulated in both groups when compared to before treatment. In addition, IL-2 concentration and SF-36 scores were much greater after treatment in the test group with respect to the control group. Levels of IL-8, TNF-α, and CRP were significantly lesser in the test group than in the control group (all, P < 0.05). ImplicationsThe combination of mecobalamin tablets and vitamin E soft capsules was effective in the treatment of recurrent oral ulcer. This combination can be used as an adjunctive therapy, offering effective pain control and improving quality of life in patients with oral ulcers.
