Brief Summary

The objective is to establish and evidence base for hyperhidrosis treatment algorithm in amputees.This project will address a problem that has troubled Service members, Veterans, and civilians with amputations for decades, impacting satisfaction with prosthetic use, residual limb skin health, and negatively affecting quality of life. Prior research in this area has been limited and insufficient. We plan to conduct an open label study of Botox, up to 400 units, to treat limb hyperhidrosis in patients with amputations. The actual dose of Botox used will be based on individual results with the Iodine-Starch test to identify areas on the residual limb that are producing excessive sweat. Botulinum Toxin A (BTX-A): Botulinum toxin therapy is well-established for use in excessive sweating of several body areas (axillary, palmar, plantar, and facial) in individuals with hyperhidrosis and inadequate response to topical treatments. Extensive research has been conducted on the efficacy and safety of BTX-A for hyperhidrosis of other areas, and it has been shown to improve both objective and subjective measures of sweating, and lead to improved quality of life measures. This will be accomplished by completing the following: Test the validity of the Minor iodine-starch test in amputees.

  1. 1.Hypothesis: The iodine-starch test is a valid diagnostic tool of hyperhidrosis and can be useful for the identification of focal areas of sweating on a residual limb.
  2. 2.Treat the residual limb Hyperhidrosis with Botox, up to and limited to 400 units.

Outcome Measures

Primary Outcomes (1)

  • The effectiveness of botulinum toxin therapy in subjects who fail Aluminum Chloride as assessed by the Hyperhidrosis Disease Severity Scale (HDSS)

    The outcome measure for this study will be measuring the Hyperhidrosis Disease Severity Scale (HDSS). The HDSS is scored on a number scale of 1-4. Score range from 1 (lowest) demonstrating sweating (hyperhidrosis) is least noticeable and does not interfere with daily activities (least impactful) to 4 (highest) sweating is intolerable and interferes significantly with daily activities. This measurement will be completed at Baseline, Week #4 clinic visit, Week #12 clinic visit, Week#16 clinic visit and week#20 follow up phone call visit.

    Baseline to 20 weeks

Secondary Outcomes (1)

  • The effectiveness of botulinum toxin therapy in subjects who fail Aluminum Chloride as assessed by the Sweating Intensity Visual Scale (SIVS)

    Baseline to 20 weeks

Study Arms (1)

Botulinum Toxin Therapy

EXPERIMENTAL

Test the effectiveness of Botulinum Toxin therapy in subjects who fail or do not tolerate Aluminum Chloride. We plan to conduct an open label study of Botox, up to 400 units, in amputees who have failed treatment with a topical antiperspirant.

Drug: Botulinum Toxin Type A (Botox)

Interventions

Maximum dose up to 400 units given one time

Also known as: Manual Muscle Testing (MMT), Labs (CBC, BMP, PFT'S, (FEV1 & FVC)), Iodine Starch Skin Test
Botulinum Toxin Therapy

Model Details: For this study, subjects will be recruited from the amputee clinics held at the Salt Lake Veteran Affairs (VA) Medical Center or the University of Utah. Combined, these clinics serve approximately 500 patients and see approximately 75 new patients each year. We plan to recruit a total of 25 subjects to this project from the two study sites. It is expected that we will enroll equal numbers from both the University of Utah and VA Medical Center.
