cannabidiol and Dermatitis--Atopic

Cannabidiol (CBD) and cannabidiolic acid (CBDA) are reported to have antinociceptive, immunomodulatory and anti-inflammatory actions.. To determine if CBD/CBDA is an effective therapy for canine atopic dermatitis (cAD).. Thirty-two privately owned dogs with cAD.. Prospective, randomised, double-blinded, placebo-controlled study. Concurrent therapies were allowed if remained unchanged. Dogs were randomly assigned to receive either 2 mg/kg of an equal mix of CBD/CBDA (n = 17) or placebo for 4 weeks. On Day (D)0, D14 and D28, Canine Atopic Dermatitis Extent and Severity Index, 4th iteration (CADESI-04) and pruritus Visual Analog Scale (pVAS) scores were determined by investigators and owners, respectively. Complete blood count, serum biochemistry profiles and cytokine bioassays were performed on serum collected on D0 and D28.. There was no significant difference in CADESI-04 from D0 to D14 (p  = 0.42) or D28 (p  = 0.51) in either group. pVAS scores were significantly lower for the treatment group at D14 (p  = 0.04) and D28 (p  = 0.01) and a significant change in pVAS from baseline was seen at D14 (p  = 0.04) and not D28 (p  = 0.054) between groups. There was no significant difference in serum levels of interleukin (IL)-6, IL-8, monocyte chemoattractant protein - 1, IL-31 or IL-34 between groups at D0 or D28. Elevated alkaline phosphatase was observed in four of 17 treatment group dogs.. CBD/CBDA as an adjunct therapy decreased pruritus, and not skin lesions associated with cAD in dogs.. Contexte - Le cannabidiol (CBD) et l'acide cannabidiolique (CBDA) auraient des actions antinociceptives, immunomodulatrices et anti-inflammatoires. Objectifs - Déterminer si le CBD/CBDA est une thérapie efficace pour la dermatite atopique canine (cAD). Animaux - Trente-deux chiens de propriétaires privés atteints de cAD Matériels et méthodes - Étude prospective, randomisée, en double aveugle, contrôlée versus placebo. Les thérapies concomitantes étaient autorisées si elles restaient inchangées. Les chiens ont été répartis au hasard pour recevoir soit 2 mg/kg d'un mélange égal de CBD/CBDA (n = 17) soit un placebo pendant quatre semaines. Aux jours (J)0, J14 et J28, les scores Canine Atopic Dermatitis Extent and Severity Index, 4th iteration (CADESI-04) et prurit Visual Analog Scale (pVAS) ont été déterminés respectivement par les investigateurs et les propriétaires. Une formule sanguine complète, des profils biochimiques sériques et des dosages biologiques des cytokines ont été réalisés sur le sérum prélevé à J0 et J28. Résultats - Il n'y avait pas de différence significative au CADESI-04 de J0 à J14 (P = 0,42) ou J28 (P = 0,51) dans les deux groupes. Les scores pVAS étaient significativement inférieurs pour le groupe de traitement à J14 (P = 0,04) et J28 (P = 0,01) et un changement significatif de la pVAS par rapport à l'inclusion a été observé à J14 (P = 0,04) et non à J28 (P = 0,054) entre les groupes. Il n'y avait pas de différence significative dans les taux sériques d'interleukine (IL)-6, IL-8, protéine chimiotactique des monocytes-1, IL-31 ou IL-34 entre les groupes à J0 ou J28. Une phosphatase alcaline élevée a été observée chez quatre des 17 chiens du groupe de traitement. Conclusions et pertinence clinique - Le CBD/CBDA en tant que traitement d'appoint a diminué le prurit, et non les lésions cutanées associées à la DAC chez les chiens.. Introducción- se ha descrito que el cannabidiol (CBD) y el ácido cannabidiólico (CBDA) tienen acciones antinociceptivas, inmunomoduladoras y antiinflamatorias. Objetivos- determinar si el CBD/CBDA es una terapia eficaz para la dermatitis atópica canina (CAD). Animales - Treinta y dos perros de propietarios privados con cAD Materiales y métodos - Estudio prospectivo, aleatorio, doble ciego, controlado con placebo. Se permitieron terapias concurrentes si permanecían sin cambios. Los perros fueron asignados al azar para recibir 2 mg/kg de una mezcla igual de CBD/CBDA (n = 17) o placebo durante cuatro semanas. En el día (D)0, D14 y D28, los investigadores y los propietarios determinaron las puntuaciones del índice de extensión y gravedad de la dermatitis atópica canina, cuarta revisión (CADESI-04) y la escala análoga visual de prurito (pVAS), respectivamente. Se realizaron hemogramas completos, perfiles bioquímicos séricos y bioensayos de citoquinas en suero obtenido en D0 y D28. Resultados- no hubo diferencias significativas en CADESI-04 de D0 a D14 (P = 0,42) o D28 (P = 0,51) en ninguno de los grupos. Las puntuaciones de pVAS fueron significativamente más bajas para el grupo de tratamiento en D14 (P = 0.04) y D28 (P = 0.01) y se observó un cambio significativo en pVAS desde el inicio en D14 (P = 0.04) y no en D28 (P = 0.054) entre grupos . No hubo diferencias significativas en los niveles séricos de interleuquina (IL)-6, IL-8, proteína quimioatrayente de monocitos-1, IL-31 o IL-34 entre los grupos en D0 o D28.

Atopic dermatitis (AD) is a common and chronic inflammatory skin disease that erupts periodically. Although the negative impact of the disorder on overall quality of life has been well established, new treatments for AD are still needed. Various studies have reported on cannabidiol's effectiveness in relieving pain and easing inflammation while not presenting major health risks.. In this communication, we aim to demonstrate the effectiveness of a novel cannabidiol (CBD) and aspartame formulation, JW-100, in relieving signs and symptoms of AD.. We conducted a double-blinded placebo-controlled interventional study randomizing patients to one of three treatment groups: JW-100 (CBD plus aspartame), CBD only, or placebo topical formulations. The Investigator's Static Global Assessment (ISGA) score was used to document any changes in AD resulting from the applied interventions at 14 days.. Fifty-seven patients completed the trial and were included in the final analysis. The ISGA score of the patients at baseline was 2.56, 2.24, and 2.24, for the JW-100, CBD, and placebo groups, respectively. After two weeks of treatment, the ISGA score reduced by 1.28, 0.81, and 0.71, for the JW-100, CBD, and placebo groups, respectively. The JW-100 cohorts demonstrated statistically significant ISGA score reduction (p = 0.042). 50% of patients in the JW-100 group achieved ISGA score of clear or almost clear (0 or 1) with at least a 2-grade improvement from baseline after treatment (p = 0.028). Only 20% and 15% of patients in the CBD only and placebo groups reported ISGA score of clear or almost clear (0 or 1).. JW-100, a novel topical formulation containing CBD and aspartame, was demonstrated to produce statistically significant improvements in AD following 14 days of topical application.

We aimed to examine the effects of cannabidiol (CBD)-containing hemp oil without delta-9-tetrahydrocannabinol (THC) as a supplemental treatment for canine atopic dermatitis (CAD), as well as its adverse effects, and effects on concurrent drug use in dogs.. In this retrospective case series, 8 dogs with CAD were diagnosed by veterinary dermatologists certified by the Japanese Society of Veterinary Dermatology.. The medical records of dogs supplemented with CBD-containing hemp oil were evaluated with respect to signalment, physical examination, plasma C-reactive protein concentrations, pharmacologic management, the CAD Extent and Severity Index (4th iteration), and the Pruritus Visual Analog Scale.. Overall, CBD, used as a supplement in combination with other drugs, was well-tolerated over a wide dose range and decreased the occurrence of pruritus in dogs with CAD when ingested twice a day.. This study provides the first report of supplementation with CBD without THC that was effective in controlling pruritic behavior in dogs with CAD.. Further controlled studies are required to investigate the dose range, efficacy, and safety.. Effets du cannabidiol sans delta-9-tétrahydrocannabinol sur la dermatite atopique canine : évaluation rétrospective de huit cas.. Nous avons cherché à examiner les effets de l’huile de chanvre contenant du cannabidiol (CBD) sans delta-9-tétrahydrocannabinol (THC) en tant que traitement complémentaire de la dermatite atopique canine (CAD), ainsi que ses effets indésirables et ses effets sur les médicaments concomitants utilisés chez le chien.. Dans cette étude rétrospective de cas, huit chiens atteints de CAD ont été diagnostiqués par des dermatologues vétérinaires certifiés par la Société japonaise de dermatologie vétérinaire.. Les dossiers médicaux des chiens supplémentés avec de l’huile de chanvre contenant du CBD ont été évalués en ce qui concerne le signalement, l’examen physique, les concentrations plasmatiques de protéine C-réactive, la gestion pharmacologique, l’indice. Dans l’ensemble, le CBD, utilisé comme supplément en association avec d’autres médicaments, a été bien toléré sur une large gamme de doses et a diminué l’apparition de prurit chez les chiens atteints de CAD lorsqu’il est ingéré deux fois par jour.. Cette étude fournit le premier rapport de supplémentation en CBD sans THC efficace pour contrôler le comportement prurigineux chez les chiens atteints de CAD.. D’autres études contrôlées sont nécessaires pour étudier la gamme de doses, l’efficacité et l’innocuité.(Traduit par D

Atopic dermatitis (AD) is a chronic skin disorder characterized by pruritus, erythema and excoriation. While AD has a multifactorial etiology, neuro-signaling pathways are now recognized to play an essential role in the pathogenesis of AD, particularly pruritus. Neuromodulators, such as topical naltrexone, are being utilized in AD treatment. Another class of neuromodulator, Palmitoylethanolamide (PEA), has demonstrated effectiveness in the treatment of itch, excoriation and erythema in AD patients. Phytocannabinoids including cannabidiol (CBD) are becoming increasingly accessible to the public and continue to be advertised for their efficacy to treat inflammatory skin disorders such as eczema. However, no human studies have been conducted to support the claim. Therefore, this study aimed to explore the effects of CBD in individuals with self-reported eczema. Twenty individuals consented to participate and 16 completed a 28-item online questionnaire assessing subjects’ disease severity using Patient Oriented Eczema Measure (POEM) and psychosocial burden of their disease through the emotional domain of Quality of Life Hand Eczema Questionnaire (QOLHEQ). Findings demonstrated a significant reduction in the mean score of POEM from baseline (mean ±SE: 16±1.35) and at a two weeks interval (8.25 ±1.80), P<0.0007. Similar reduction was seen in emotional domain of QOLHEQ from a mean score of 20.9±2.06 to 8.375 ±1.609 at 2 week-interval, P<0.004. 67% of subjects reported a decrease in itch and 50% perceived an improvement in their eczema by more than 60%. This observational study shed light on the potential clinical utility of topical CBD in the treatment of atopic dermatitis. J Drugs Dermatol. 2020;19(12): doi:10.36849/JDD.2020.5464.
