LLLT of Trophic Ulcers of Lower Extremities and Chronic Venous Insufficiency

February 22, 2018 updated by: Research Center Matrix

New Combined Laser Therapy in Patients With Trophic Ulcers of Lower Extremities and Chronic Venous Insufficiency

The aim of this study was to evaluate comparatively the efficiency of traditional treatment methods in patients with chronic venous diseases of C6 class, and a new combined low level laser therapy (LLLT) by LASMIK device.

The results of outpatient examination and treatment of patients with venous trophic ulcers, observed in the City Polyclinic of "Tula Municipal Clinical Hospital №2" were analyzed.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

During a longitudinal study, a group of patients was followed up in the period of complete or partial recovery. International classification of lower extremity chronic venous disorders СЕАР was used as a clinical classification of chronic venous insufficiency (CVI).

Depending on the applied treatment method, patients were divided into 2 groups:

  1. (n=34) Conventional treatment
  2. (n=34) Conventional treatment + combined LLLT, including external exposure with 635nm wavelength + intravenous laser blood illumination (ILBI) with 365-405nm (UV-spectrum) and 520-525nm (green spectrum) wavelength alternately, according to the special scheme

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Active Comparator: Conventional treatment

Conventional treatment only.

  • An elastic compression of lower extremities: elastic bandages or compression hosiery of class 2
  • Pharmacotherapy: Anavenol, Aescusan, Glyvenol; drugs of the Benzopyrone group, including Troxevasin and Venoruton. Trental, Aspirin and Ticlid (Ticlopidine). Nonsteroidal anti-inflammatory drugs (Nimesil, OKI), various ointments containing Heparin, corticosteroids, as well as nonsteroidal anti-inflammatory drugs. Antibiotic therapy.
  • Topical treatment: in the presence of purulent discharge (phase I of the wound healing process) - bandaging with antiseptic solutions (1% Iodopiron solution, 0.1% Chlorhexidine solution) and hydrophilic ointments (Levosin, Levomecol). In phases II and III - after ulcer cleansing the preparations based on Hyaluronic acid (Curiozin).

Experimental: Conventional therapy and combined LLLT

Conventional therapy and combined LLLT (LASMIK device) was performed.

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Trophic Ulcer Healing
Time Frame: 6 months follow up
