Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study tests two types of lasers (ND YAG 1064 short and ultra-short pulses) to treat hyperchromic skin lesions secondary to venous hypertension (stasis dermatitis)

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Background: Stasis dermatitis with hyperpigmented skin lesions is a serious health problem for patients with chronic venous hypertension. Although no randomized studies have evaluated lasers for this treatment, lasers can be an attractive option.

Methods: This prospective, randomized, 3-arm, open-label, vehicle-controlled study will enroll patients scheduled to undergo treatment for stasis dermatitis with hyperpigmented skin lesions. Patients will be allocated to either Nd: YAG 1064 nm short pulse laser-nanoseconds (group 1), or Nd: YAG 1064 nm ultra-short-pulse laser-picoseconds (group 2), or cold cream vehicle control (group 3). All treatments are scheduled for 6 visits with pre-defined dates, with a final follow-up visit at intervals of 28 to 35 days. Primary outcomes include colorimetry analysis, secondary outcomes pre- and post-photographic analysis, and DLQI quality-of-life assessment.

Conclusions: The results of this trial will provide high-quality evidence to guide clinical practice on optimal management of hyperpigmented skin lesions secondary to stasis dermatitis.

Arm 1: ND YAG laser: 1064 nm short pulse (nanoseconds) - Omer Smart

Laser treatment

Group Type EXPERIMENTAL

short-pulse ND: YAG 1064 laser

Intervention Type PROCEDURE

Nd: YAG 1064 nm short pulse laser (5 nanoseconds), 4 mm spot size, from 100 to 1000 mJ total energy, treatment scheduled for six visits with pre-defined dates, with intervals of 28 to 35 days. The device will be Omer Smart, a Q-Switch Laser produced by Medical San (Lajeado, RS, Brazil).

Arm 2: ND YAG laser: 1064 nm ultra- short pulse (picoseconds) - omer Premium

Laser treatment

Group Type EXPERIMENTAL

ultra-short-pulse ND: YAG 1064 laser

Intervention Type PROCEDURE

Nd: YAG1064 nm ultra-short pulse laser (400 picoseconds), 2 to 10 mm spot size, from 100 to 1000 mJ total energy, treatment scheduled for 6 visits with pre-defined dates, with intervals of 28 to 35 days. The device will be Omer Premium, a picolaser produced by Medical San (Lajeado, RS, Brazil).

Arm 3

Control vehicle (cold cream)

Group Type PLACEBO_COMPARATOR

cold cream

Intervention Type DRUG

The control vehicle is a cold cream, supplied by HERVA'S manipulation pharmacy. The composition of cold cream will be beeswax, acetyl palmitate, BHA, cetearyl alcohol, propylparaben, and water. This topical agent will be applied to patients daily throughout the treatment period. It is scheduled for six visits with pre-defined dates, with intervals of 28 to 35 days.
