Quality of life before hyperhidrosis treatment as a predictive factor for oxybutynin treatment outcomes in palmar and axillary hyperhidrosis.

Studies have suggested that quality of life (QOL) evaluation before video-assisted thoracoscopic sympathectomy for patients with hyperhidrosis may serve as a predictive factor for positive postoperative outcomes. Our study aims to analyze if this tendency is also observed in patients treated with oxybutynin for palmar and axillary hyperhidrosis.
Five hundred sixty-five patients who submitted to a protocol treatment with oxybutynin were retrospectively analyzed between January 2007 and January 2012 and were divided into 2 groups according to QOL assessment before treatment. The groups consisted of 176 patients with "poor" and 389 patients with "very poor" QOL evaluation before oxybutynin treatment. Outcomes involving improvements in QOL and clinical progression of hyperhidrosis were evaluated using a validated clinical questionnaire that was specifically designed to assess satisfaction in patients with excessive sweating.
Improvements in hyperhidrosis after oxybutynin were observed in 65.5% of patients with very poor pretreatment QOL scores and in 75% of patients with poor pretreatment QOL scores, and the only adverse event associated with oxybutynin treatment was dry mouth, which was observed with greater intensity in patients with very poor initial QOL evaluation.
Improvements in hyperhidrosis after oxybutynin treatment were similar in both groups, suggesting that QOL before treatment is not a predictive factor for clinical outcomes, contrasting with surgical results that disclose significantly better results in patients with initially poorer QOL analysis.
