Comparison of Vortioxetine Versus Other Antidepressants With Pregabalin Augmentation in Burning Mouth Syndrome

Federico II University203 enrolled

Overview

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.

Primary Outcomes

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).
