A new treatment paradigm for sickle cell disease leg ulcers: Topical cannabis-based medicines

Topical Cannabidiol in the Treatment of Digital Ulcers in Patients with Scleroderma: Comparative Analysis and Literature Review

OBJECTIVE

To explore the effect of topical cannabidiol (CBD) in treating digital ulcers in patients with systemic sclerosis (SSc).

METHODS

In total, 45 patients with SSc who had digital ulcers were consecutively enrolled between January 2019 and December 2019. Of the participants, 25 were treated with CBD during surgical debridement and 20 were treated with standard local therapy. A numeric rating scale for pain and Health Assessment Questionnaire Disability Index were administered at the baseline and at the end of treatment.

RESULTS

Local treatment with CBD was significantly associated with lower pain scores, higher health assessment scores, and an increase in participants' total hours of sleep. Patients in the control group more frequently required additional analgesic therapy.

CONCLUSIONS

Topical CBD may be a valuable tool to treat pain related to digital ulcers in patients with SSc.

Evidence-based Potential Therapeutic Applications of Cannabinoids in Wound Management

BACKGROUND

Although wound management is a major component of all domains of healthcare, conventional therapeutics have numerous limitations. The endocannabinoid system of the skin, one of the major endogenous systems, has recently been connected to wound healing. Cannabinoids and their interactions with the endogenous chemical signaling system may be a promising therapeutic option because they address some of the fundamental pathways for physiologic derangement that underpin chronic integumentary wounds.

RECENT ADVANCES

The therapeutic applications of cannabinoids are increasing because of their legalization and resulting market expansion. Recently, their immunosuppressive and anti-inflammatory properties have been explored for the treatment of wounds that are not effectively managed by conventional medicines.

CRITICAL ISSUES

Failure to manage wounds effectively is associated with reduced quality of life, disability, mortality, and increased healthcare expenditures. Therapeutic options that can manage wounds effectively and efficiently are needed. In this review, the authors summarize recent advances on the use of cannabinoids to treat skin disorders with an emphasis on wound management.

FUTURE DIRECTIONS

Effective wound management requires medicines with good therapeutic outcomes and minimal adverse effects. Despite the promising results of cannabinoids in wound management, further controlled clinical studies are required to establish the definitive role of these compounds in the pathophysiology of wounds and their usefulness in the clinical setting.

Topical cannabis-based medicines - A novel adjuvant treatment for venous leg ulcers: An open-label trial

Venous leg ulcers are highly prevalent lower limb integumentary wounds that remain challenging to heal despite the use of evidence-based compression therapies. A multitude of adjuvant treatments has been studied but none have demonstrated enough efficacy to gain adoption into treatment guidelines. Global attention on Cannabis-Based Therapies is increasing and has been driven by quantum scientific advancements in the understanding of the endocannabinoid signalling system. Topical Cannabis-Based Medicines represent a novel treatment paradigm for venous leg ulcers in terms of promoting wound closure. Fourteen complex patients with sixteen recalcitrant leg ulcers were treated with Topical Cannabis-Based Medicines in conjunction with compression bandaging, every second day, to both wound bed and peri-wound tissues. The cohort had a mean age of 75.8 years and was medically complex as reflected by a mean M3 multimorbidity index score of 2.94 and a mean Palliative Performance Scale score of 67.1%. Complete wound closure, defined as being fully epithelialized, was achieved among 11 patients (79%) and 13 wounds (81%) within a median of 34 days. All three remaining patients demonstrated progressive healing trends but were lost to follow-up. The treatments were well tolerated, and no significant adverse reactions were experienced. The rapid wound closure of previously non-healing venous leg ulcers among elderly and highly complex patients suggests that Topical Cannabis-Based Medicines may become effective adjuvants in conjunction with compression therapy. This may also indicate that they may have an even broader role within integumentary and wound management. Therefore, this treatment paradigm warrants being subjected to controlled trials.
