Brief Summary

Background: The treatment of Burning Mouth Syndrome (BMS) presents a challenge in tailoring appropriate medication for individual patients. Antidepressants have demonstrated efficacy in alleviating symptoms in most cases; however, a subset of patients exhibit limited or no response to these treatments. The augmentation with pregabalin to conventional treatment has shown promising outcomes in relieving pain and improving quality of life in chronic pain conditions. This study aimed to compare the efficacy of vortioxetine with other antidepressants (SSRIs/SNRIs) in combination with pregabalin in a cohort of unresponsive BMS patients and to predict treatment response using clinical data. Methods: A 52-week randomized, open-label, active-controlled study was conducted, enrolling 203 BMS patients previously treated with one antidepressant for 12 weeks and non-responder to the treatment. The study sample have included two groups: Group A (136) received vortioxetine, while Group B (67) received SSRIs/SNRIs. Pregabalin (75mg/day) was added to both groups, with a potential dosage increase to 150mg/day for inadequate responders after 12 weeks. Treatment response was assessed by measuring reduction in VAS and SF-MPQ scores (\>50 or 1-2) and HAM-A and HAM-D scores (\>50% or ≤7) at 12, 24, 36 and 52 weeks. Classical logistic regression with a stepwise algorithm and Random Forest machine learning models were used to predict treatment response.

Outcome Measures

Primary Outcomes (2)

  • Visual Analog Scale (VAS)

    The Visual Analog Scale (VAS) (Hayes and Patterson, 1921) is a well-validated unidimensional instrument for the measure of pain intensity (Hawker et al., 2011). The score is determined by measuring the distance on the line between the "no pain" and the mark of a patient mark, providing a range of scores from 0 to 10 (0 = no oral symptoms and 10 = the worst imaginable discomfort).

    4 times evaluation: time 0: 0 week; time 1: 12 weeks; time 2: 24 weeks; time 3: 36 weeks; time 4: 52 weeks

  • Short-form McGill Pain Questionnaire (SF-MPQ)

    the short form of the McGill Pain Questionnaire (SF-MPQ) is a measure of the quality of pain and is a multidimensional pain questionnaire, which measures the sensory, affective, and evaluative aspects of the perceived pain (Hawker et al., 2011). It comprises 15 items from the original MPQ, each scored from 0 (none) to 3 (severe). The SF-MPQ score is obtained by summing the item scores (range 0-45). There are no established critical cutoff points for the interpretation of the scores and, as for the MPQ, a higher score indicates the worse pain.

    4 times evaluation: time 0: 0 week; time 1: 12 weeks; time 2: 24 weeks; time 3: 36 weeks; time 4: 52 weeks

Secondary Outcomes (3)

  • Hamilton rating scale for Depression (HAM-D)

    4 times evaluation: time 0: 0 week; time 1: 12 weeks; time 2: 24 weeks; time 3: 36 weeks; time 4: 52 weeks

  • Hamilton rating scale for Anxiety (HAM-A)

    4 times evaluation: time 0: 0 week; time 1: 12 weeks; time 2: 24 weeks; time 3: 36 weeks; time 4: 52 weeks

  • Pittsburgh Sleep Quality Index (PSQI)

    4 times evaluation: time 0: 0 week; time 1: 12 weeks; time 2: 24 weeks; time 3: 36 weeks; time 4: 52 weeks

Other Outcomes (1)

  • Clinical Global Impression Scale - Improvement (CGI-I) and Severity (CGI-S)

    3 times evaluation: time 1: 12 weeks; time 2: 24 weeks; time 3: 36 weeks; time 4: 52 weeks
