Please use this link to access publication Abstract Purpose To describe the presence, type, and management of drug-drug interactions (DDIs) at prescription cannabidiol (CBD) therapy initiation. Methods We conducted a single-center, retrospective study of patients prescribed CBD from a medical center’s neurology clinic for seizure management from January 2019 through April 2020. Patients were excluded if they were enrolled in a CBD clinical trial or the insurance approval or medication fulfillment process was not completed by the center’s specialty pharmacy. The primary outcomes were the numbers, types, and management of DDIs identified at the time of CBD prescribing. Results Of the 136 patients included,...

Abstract: Of the 37.9 million individuals infected with human immunodeficiency virus type 1 (HIV-1), approximately 50% exhibit HIV-associated neurocognitive disorders (HAND). We and others previously showed that HIV-1 viral RNAs, such as trans-activating response (TAR) RNA, are incorporated into extracellular vesicles (EVs) and elicit an inflammatory response in recipient naïve cells. Cannabidiol (CBD) and ∆9-tetrahydrocannabinol (THC), the primary cannabinoids present in cannabis, are effective in reducing inflammation. Studies show that cannabis use in people living with HIV-1 is associated with lower viral load, lower circulating CD16+ monocytes and high CD4+ T-cell counts, suggesting a potentially therapeutic application. Here, HIV-1 infected U1 monocytes and primary...

Please use this link to access publication Abstract Background Autism spectrum disorder is specifically approved for medical cannabis consumption in 20 U.S. states, the District of Columbia, and the Territory of Puerto Rico. Despite increased access, there is limited knowledge about who consumes medical cannabis, what they consume, and perceived effectiveness. We addressed these gaps by conducting a natural history study of medical cannabis consumption. Method Children and their families engaged with a large pediatric care system were recruited to complete a telephonic study regarding their medical cannabis consumption. All children had to be consuming approved medical cannabis products issued from a state that had legalized medical cannabis for the treatment of ASD or related behaviors (irritability, hyperactivity, anxiety)...

Please use this link to access publication Abstract Gulf War Illness (GWI) corresponds to an array of symptoms that includes chronic fatigue, musculoskeletal pain, cognitive dysfunction, sleep disturbance, gastrointestinal, respiratory, and dermatological symptoms that affect ~250,000 U.S. military veterans that served in Operation Desert Storm/Desert Shield (1990-1991). Mitochondrial function impairments have been shown in GWI patients. GWI patients report partial amelioration of chronic fatigue and brain fog after medicinal marijuana and CBD oils. Interestingly, cannabidiol (CBD) modulates mitochondrial physiology though this has not been characterized in detail. We hypothesize that GWI mitochondrial pathology can be recapitulated in dermal fibroblasts (DF) from subjects to help...

Please use this link to access publication Abstract Background Cannabis sativa L. extracts (CSE) are used for treating inflammatory conditions, but little is known about their immunomodulatory effects. We investigated a novel CSE with high (14%) CBD and low (0.2%) THC concentration in comparison with pure CBD on primary human lymphocytes. Methods Proliferation, cell cycle distribution, apoptosis/necrosis and viability were analysed with standard methods. Genotoxicity was evaluated with the comet-assay. The effect on T lymphocyte activation was evaluated via CD25/CD69 marker expression, degranulation assays and the production of cytokines. The influence on the transcription factors was analysed using Jurkat reporter cell lines. Specific CB2 receptor antagonist SR144528 and TRPV1 receptor antagonist...

Abstract Background Cannabidiol (CBD) and cannabidiolic acid (CBDA) are reported to have antinociceptive, immunomodulatory and anti-inflammatory actions. Objectives To determine if CBD/CBDA is an effective therapy for canine atopic dermatitis (cAD). Animals Thirty-two privately owned dogs with cAD. Materials and methods 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...

ABSTRACT This phase II clinical trial investigates a one-time oromucosal dose of tetrahydrocannabinol/cannabidiol (THC/CBD) in 23 patients with indolent leukemic B cell lymphomas. Primary endpoint was a significant reduction in leukemic B cells. Grade 1  2 adverse events were seen in 91% of the patients; most common were dry mouth (78%), vertigo (70%), and somnolence (43%). After THC/CBD a significant reduction in leukemic B cells (median, 11%) occurred within two hours (p ¼ .014), and remained for 6 h without induction of apoptosis or proliferation. Normal B cells and T cells were also reduced. CXCR4 expression increased on leukemic cells and T cells....

Please use this link to access publication Abstract Obsessive-compulsive disorder (OCD) is a neuropsychiatric disorder characterized by recurrent and distinctive obsessions and/or compulsions. The etiologies remain unclear. Recent findings have shown that oxidative stress, inflammation, and glutamatergic pathways play key roles in the causes of OCD. However, first-line therapies include cognitive-behavioral therapy but only 40% of the patients respond to this first-line therapy. Research for new treatment is mandatory. This review focuses on the potential effects of cannabidiol (CBD), as a potential therapeutic strategy, on OCD and some of the presumed mechanisms by which CBD provides its benefit properties. CBD medication downregulates GSK-3β, the...

Please use this link to access publication Abstract Background Methamphetamine (MA) abuse is a major global public health problem. However, it is not yet known whether cannabidiol (CBD) has protective effects on MA-induced cardiotoxicity. The present study investigated whether CBD has protective effects on MA-induced cardiac damage in rats via the protein kinase A/cyclic adenosine monophosphate (cAMP)-response element-binding protein (PKA/CREB) pathway. Methods A total of 30 rats were randomly divided into 5 groups. The rats were administered MA (10 mg/kg) by intraperitoneal (IP) injection once a day for 4 weeks, and with CBD (40 or 80 mg/kg, IP) treatment 1 h before the MA...

Abstract There is evidence that demonstrates the effect of cannabinoid agonists inhibiting relevant aspects in lung cancer, such as proliferation or epithelial-to-mesenchymal transition (EMT). Most of these studies are based on evidence observed in in vitro models developed on cancer cell lines. These studies do not consider the complexity of the tumor microenvironment (TME). One of the main components of the TME is cancer-associated fibroblasts (CAFs), cells that are relevant in the control of proliferation and metastasis in lung cancer. In this work, we evaluated the direct effects of two cannabinoid agonists, tetrahydrocannabinol (THC) and cannabidiol (CBD), used alone or in combination, on CAFs...
