Effect of Sclerotherapy on Fistulas and Sinus Tracts in Hidradenitis Suppurativa

A Single Center Clinical Trial to Evaluate the Effect of Sclerotherapy on Fistulas and Sinus Tracts in Adult Patients With Hidradenitis Suppurativa

This study evaluates the effect of hypertonic saline 23.4% injection in fistulas or sinus tracts in adult patients with hidradenitis suppurativa.

Study Overview

• Status: Completed
• Conditions: Hidradenitis Suppurativa
• Intervention / Treatment: Drug: 23.4% Hypertonic saline

Detailed Description

The clinical effect of the hypertonic saline treatment will be evaluated with Physician Assessments at week 2 (t=2), week four (t=4) and week 8 (t=8) and compared with the first visit (baseline) (t=0). If necessary, subjects will be eligible to receive another hypertonic saline injected in week 2 and/or week 4, with a maximum of three injections. Simultaneously improvement will be assessed by ultrasound if possible, using the Philips Lumify Ultrasound Device, and by patients using HS Improvement Assessments. Pain and stinging during treatment sessions will be monitored using numeric rating scales (NRS). For monitoring quality of life the DLQI will be used.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
HS Physician Local Improvement assessment	Percent change in clinical efficacy will be measured by Physician Assessments: HS Physician Local Improvement Assessment. Scale allows physician to score multiple HS symptoms on a scale from 'extremely worse' to 'very much improved'.	Baseline and Week 8

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Numeric Rating Scale for Stinging	Self-reported median pain and stinging intensity during and directly after treatment with Hypertonic saline injections.	Baseline and visit 8
Numeric Rating Scale for Pain	Self-reported median pain and stinging intensity during and directly after treatment with Hypertonic saline injections.	Baseline and visit 8
Length of fistula	Measuring the length and the lumen of the fistulas using ultrasound if possible.	Baseline and visit 8
Dermatology Life Quality Index	Mean score patient-reported outcomes based on Dermatology Life Quality Index (DLQI).	Baseline to Visit 8
HS Patient Local Improvement assessment	Percentage change in Patient improvement assessment about state of the disease over the last 24hours.	Baseline to Visit 8
