AIM: This study presents a systematic review of the therapeutic potential and safety profile of thalidomide in managing minor recurrent aphthous stomatitis (RAS).
METHODS: A PRISMA-guided systematic review was conducted using PubMed, Cochrane, ScienceDirect, Google Scholar, Semantic Scholar, and Wangfang. The search was performed from January 2014 to April 2025. Studies were selected based on the participants, intervention, control, and outcome (PICO) framework: (1) Population: Healthy individuals with minor RAS; (2) Intervention: Thalidomide; (3) Comparison: Placebo or standard therapy; (4) Outcomes: Recurrence interval, number of ulcers, healing time, pain intensity, complete and partial response rates, ulcer-free period, immunological parameters, and adverse effects.
RESULTS: Out of 1,600 initially retrieved records, 404 titles and abstracts were screened after removing duplicates, and 21 full texts were assessed. Five randomized clinical trials (RCTs) involving 607 participants met the eligibility criteria, which showed that thalidomide, especially at 25 mg/day for 8 weeks, significantly prolonged recurrence intervals and reduced ulcer count in patients with minor RAU. This regimen also resulted in the longest ulcer-free and relapse-free periods. Pain reduction and healing time improvement were inconsistent across studies. Some trials reported significant reductions in inflammatory markers (IL-6, TNF-α), especially with the 25 mg regimen. Combination therapy with multivitamins or glucosides of Paeony showed potential added benefits. Thalidomide was generally well tolerated, but mild side effects were more common compared to non-thalidomide treatments. Risk of bias was low for randomization but unclear or high in blinding and allocation.
CONCLUSION: Thalidomide at a dose of 25 mg/day for 8 weeks appears effective in managing minor RAS by prolonging recurrence intervals and modulating anti-inflammatory markers. Its overall acceptable safety profile supports its consideration in selected patients; however, clinicians should remain vigilant for potential mild side effects.
CLINICAL SIGNIFICANCE: Thalidomide administered at 25 mg/day for 8 weeks demonstrates meaningful clinical benefits for patients with recurrent minor aphthous ulcers by notably prolonging remission intervals and lowering ulcer frequency and provides anti-inflammatory advantages, making it a valuable therapeutic option for patients who do not respond adequately to conventional treatments. While generally well tolerated, with mainly mild adverse effects, careful patient selection and monitoring remain essential to minimize risks and maximize therapeutic outcomes.
