“Proceedings of an Almirall-sponsored satellite symposium held at the 34th Congress of the European Committee for Treatment and Research in Multiple Sclerosis in Berlin, Germany, 10 October 2018.” https://www.futuremedicine.com/doi/10.2217/nmt-2018-0048

“Newest evidence for tetrahydrocannabinol:cannabidiol oromucosal spray from postapproval pragmatic studies. Postapproval studies have an essential role in demonstrating that an intervention is effective and well tolerated during use in daily clinical practice. Numerous large observational and registry studies of tetrahydrocannabinol (THC):cannabidiol (CBD) oromucosal spray have been conducted subsequent to its approval in Europe in 2011. Collectively, these studies provide valuable insight into various aspects of THC:CBD spray during real-world use in patients with multiple sclerosis spasticity, including its long-term effectiveness and tolerability. The Italian Medicines Agency’s web-based registry is the largest observational study of THC:CBD oromucosal spray conducted to date, reporting on more than 1600 patients prescribed THC:CBD spray since it was introduced in Italy in 2013, and further supporting its effectiveness and tolerability profile.” https://www.futuremedicine.com/doi/10.2217/nmt-2018-0049

“Newest evidence for tetrahydrocannabinol:cannabidiol oromucosal spray from randomized clinical trials. Subsequent to EMA approval of tetrahydrocannabinol (THC): cannabidiol (CBD) oromucosal spray based on results of various studies, including an enriched-design clinical trial, two newer postapproval randomized trials have confirmed its efficacy and safety for treating resistant multiple sclerosis spasticity, while simultaneously addressing specific authorities’ concerns. A double-blind, placebo-controlled, Phase IV trial, conducted as part of the EMA’s risk management plan, found no effect of THC:CBD spray on cognition and mood after 50 weeks of treatment. In the Sativex® as add-on therapy versus further optimized first-line ANTispastics (SAVANT)  study, add-on THC:CBD spray was significantly more effective than readjusting standard antispasticity therapy and provided new evidence of efficacy as requested by German authorities. SAVANT results support practical recommendations for treating resistant multiple sclerosis spasticity in daily practice.”  https://www.futuremedicine.com/doi/10.2217/nmt-2018-0050

Scientific Reports

“There has been a dramatic increase in the number of children diagnosed with autism spectrum disorders (ASD) worldwide. Recently anecdotal evidence of possible therapeutic effects of cannabis products has emerged.

The aim of this study is to characterize the epidemiology of ASD patients receiving medical cannabis treatment and to describe its safety and efficacy.

We analysed the data prospectively collected as part of the treatment program of 188 ASD patients treated with medical cannabis between 2015 and 2017. The treatment in majority of the patients was based on cannabis oil containing 30% CBD and 1.5% THC. Symptoms inventory, patient global assessment and side effects at 6 months were primary outcomes of interest and were assessed by structured questionnaires.

After six months of treatment 82.4% of patients (155) were in active treatment and 60.0% (93) have been assessed; 28 patients (30.1%) reported a significant improvement, 50 (53.7%) moderate, 6 (6.4%) slight and 8 (8.6%) had no change in their condition. Twenty-three patients (25.2%) experienced at least one side effect; the most common was restlessness (6.6%).

Cannabis in ASD patients appears to be well tolerated, safe and effective option to relieve symptoms associated with ASD.”

“Endometriosis has a significant negative impact on the lives of women, and current medical treatments often do not give sufficient pain relief or have intolerable side effects for many women. The majority of women with primary dysmenorrhea use self-management strategies (including self-care techniques or lifestyle choices) to help manage period related symptoms, but little is known about self-management in women with endometriosis.

The aim of this survey was to determine the prevalence of use, safety, and self-rated effectiveness of common forms of self-management.

Cannabis, heat, hemp/CBD oil, and dietary changes were the most highly rated in terms of self-reported effectiveness in pain reduction. Physical interventions such as yoga/Pilates, stretching, and exercise were rated as being less effective.

Self-management was very commonly used by women with endometriosis and form an important part of self-management.

Women using cannabis reported the highest self-rated effectiveness.”

“Cannabinoids have antispastic and analgesic effects; however, their role in the treatment of multiple sclerosis (MS) symptoms is not well defined.

OBJECTIVE:

To conduct a systematic review and meta-analysis to assess the efficacy and tolerability of medicinal cannabinoids compared with placebo in the symptomatic treatment of patients with MS.

STUDY SELECTION:

Randomized, double-blind, and placebo-controlled trials evaluating the effect of medicinal cannabinoids by oral or oromucosal route of administration on the symptoms of spasticity, pain, or bladder dysfunction in adult patients with MS.

RESULTS:

Seventeen selected trials including 3161 patients were analyzed. Significant findings for the efficacy of cannabinoids vs placebo were SMD = -0.25 SD (95% CI, -0.38 to -0.13 SD) for spasticity (subjective patient assessment data), -0.17 SD (95% CI, -0.31 to -0.03 SD) for pain, and -0.11 SD (95% CI, -0.22 to -0.0008 SD) for bladder dysfunction. Results favored cannabinoids. Findings for tolerability were RR = 1.72 patient-years (95% CI, 1.46-2.02 patient-years) in the total adverse events analysis and 2.95 patient-years (95% CI, 2.14-4.07 patient-years) in withdrawals due to adverse events. Results described a higher risk for cannabinoids. The serious adverse events meta-analysis showed no statistical significance.

CONCLUSIONS AND RELEVANCE:

The results suggest a limited efficacy of cannabinoids for the treatment of spasticity, pain, and bladder dysfunction in patients with MS. Therapy using these drugs can be considered as safe.”

 “The present review will provide an overview of the neurobiology, epidemiology, clinical impact, and treatment of cannabis use disorder (CUD) in mood disorders.

Patients with mood disorders including major depressive disorder (MDD) and bipolar disorder (BD) have higher rates of cannabis use, and CUD compared to the general population. Reasons for this association are not clear, nor are the putative therapeutic effects of cannabis use, or its components delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), in these illnesses.

Cannabis use may be associated mood disorders, but more research is needed to increase our understanding of the mechanisms for this association, and to develop more effective treatments for this comorbidity.”

Do Endocannabinoids Regulate Glucose Reabsorption in the Kidney?

“Diabetic nephropathy (DN), a distinct manifestation of diabetic kidney disease, affects approximately 30% of patients with diabetes. While most attention has been focused on glomerular changes related to DN, there is growing evidence that tubulopathy is a key feature in the pathogenesis of this disease. The renal proximal tubule cells (RPTCs) are particularly sensitive to the deleterious effect of chronic hyperglycemia. However, the cellular changes that control the dysfunction of the RPTCs are not fully understood.

Controlling glucose reabsorption in the proximal tubules via inhibition of glucose transporters (GLUT) has emerged as a promising therapeutic in ameliorating DN.

Overactivation of the renal endocannabinoid (eCB) system via the cannabinoid-1 receptor (CB1R) contributes to the development of DN, and its blockade by globally acting or peripherally restricted CB1R antagonists has been shown to ameliorate renal dysfunction in different murine models for diabetes. Recently, we have utilized various pharmacological and genetic tools to show that the eCB/CB1R system contributes to the development of DN via regulating the expression, translocation, and activity of the facilitative GLUT2 located in the RPTCs.

These findings have the potential to be translated into therapy, and support the rationale for the preclinical development of novel renal-specific CB1R and/or GLUT2 inhibitors for the treatment of DN.”

 “Complementary therapies for inflammatory bowel disease (IBD) have earned growing interest from patients and investigators alike, with a dynamic landscape of research in this area. In this article, we review results of the most recent studies evaluating the role of cannabis and turmeric for the treatment of IBD and other intestinal illnesses.

RECENT FINDINGS:

Cannabinoids are well-established modulators of gut motility and visceral pain and have demonstrated anti-inflammatory properties. Clinical trials suggest that there may be a therapeutic role for cannabinoid therapy in the treatment of IBD, irritable bowel syndrome (IBS), nausea and vomiting, and GI motility disorders. Recent reports of serious adverse effects from synthetic cannabinoids highlight the need for additional investigation of cannabinoids to establish their efficacy and safety. Turmeric trials have demonstrated some promise as adjuvant treatment for IBD, though not in other GI disease processes. Evidence suggests that the use of cannabis and turmeric is potentially beneficial in IBD and IBS; however, neither has been compared to standard therapy in IBD, and thus should not be recommended as alternative treatment for IBD. For cannabis in particular, additional investigation regarding appropriate dosing and timing, given known adverse effects of its chronic use, and careful monitoring of potential bleeding complications with synthetic cannabinoids are imperative.”

Preclinical safety and efficacy of cannabidivarin for early life seizures.

Neuropharmacology

“A significant proportion of neonatal and childhood seizures are poorly controlled by existing anti-seizure drugs (ASDs), likely due to prominent differences in ionic homeostasis and network connectivity between the immature and mature brain. In addition to the poor efficacy of current ASDs, many induce apoptosis, impair synaptic development, and produce behavioral deficits when given during early postnatal development.

There is growing interest in new targets, such as cannabidiol (CBD) and its propyl analog cannabidivarin (CBDV) for early life indications. While CBD was recently approved for treatment of refractory childhood epilepsies, little is known about the efficacy or safety of CBDV.

Here, we addressed this gap through a systematic evaluation of CBDV against multiple seizure models in postnatal day (P) 10 and 20 animals. We also evaluated the impact of CBDV on acute neurotoxicity in immature rats.

CBDV (50-200 mg/kg) displayed an age and model-specific profile of anticonvulsant action.

Finally, CBDV treatment generally avoided induction of neuronal degeneration in immature rats.

Together, the efficacy and safety profile of CBDV suggest it may have therapeutic value for early life seizures.”

Cannabis sativa L. and Nonpsychoactive Cannabinoids: Their Chemistry and Role against Oxidative Stress, Inflammation, and Cancer.

 Related image“In the last decades, a lot of attention has been paid to the compounds present in medicinal Cannabis sativa L., such as Δ9-tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD), and their effects on inflammation and cancer-related pain.

The National Cancer Institute (NCI) currently recognizes medicinal C. sativa as an effective treatment for providing relief in a number of symptoms associated with cancer, including pain, loss of appetite, nausea and vomiting, and anxiety.

Several studies have described CBD as a multitarget molecule, acting as an adaptogen, and as a modulator, in different ways, depending on the type and location of disequilibrium both in the brain and in the body, mainly interacting with specific receptor proteins CB1 and CB2.

CBD is present in both medicinal and fibre-type C. sativa plants, but, unlike Δ9-THC, it is completely nonpsychoactive. Fibre-type C. sativa (hemp) differs from medicinal C. sativa, since it contains only few levels of Δ9-THC and high levels of CBD and related nonpsychoactive compounds.

In recent years, a number of preclinical researches have been focused on the role of CBD as an anticancer molecule, suggesting CBD (and CBD-like molecules present in the hemp extract) as a possible candidate for future clinical trials.

CBD has been found to possess antioxidant activity in many studies, thus suggesting a possible role in the prevention of both neurodegenerative and cardiovascular diseases. In animal models, CBD has been shown to inhibit the progression of several cancer types. Moreover, it has been found that coadministration of CBD and Δ9-THC, followed by radiation therapy, causes an increase of autophagy and apoptosis in cancer cells. In addition, CBD is able to inhibit cell proliferation and to increase apoptosis in different types of cancer models.

These activities seem to involve also alternative pathways, such as the interactions with TRPV and GRP55 receptor complexes. Moreover, the finding that the acidic precursor of CBD (cannabidiolic acid, CBDA) is able to inhibit the migration of breast cancer cells and to downregulate the proto-oncogene c-fos and the cyclooxygenase-2 (COX-2) highlights the possibility that CBDA might act on a common pathway of inflammation and cancer mechanisms, which might be responsible for its anticancer activity.

In the light of all these findings, in this review we explore the effects and the molecular mechanisms of CBD on inflammation and cancer processes, highlighting also the role of minor cannabinoids and noncannabinoids constituents of Δ9-THC deprived hemp.”

Physical Medicine and Rehabilitation Clinics of North America

“Multiple sclerosis is a progressive autoimmune neurologic disorder that may affect any region of the central nervous system. Spasticity in patients with multiple sclerosis can be debilitating and detrimental to the function and quality of life of patients. Treatment options include oral medications, chemodenervation, physical therapy, and modalities.

Cannabinoids in the form of a delta-9-tetrahydrocannabinol/cannabidiol oro-mucosal spray has been shown to be effective in addressing spasticity in multiple sclerosis.

Successful treatment of spasticity will be integrated, multimodal, and individualized.”
