Medical Cannabis in Treatment of Resistant Familial Mediterranean Fever.

 Logo“Colchicine-resistant familial Mediterranean fever can be treated by anti-IL-1 biologic therapy; however, such treatment needs approval by the health insurance company, and many patients are denied such treatment or do not respond to it.

CASE REPORT Two familial Mediterranean fever (FMF) patients, both homozygous for M694V mutation and resistant to colchicine treatment, were treated with medical cannabis. Prior to that, 1 patient was denied biologic treatment and the other had no significant response to anakinra.

Under medical cannabis treatment, both patients had remarkable improvement in the severity of the attacks and also a decrease in the frequency of the attacks, from once every 2 weeks to 1 attack every month in 1 patient; this patient had also a remarkable reduction in the C-reactive protein level during the attacks.

CONCLUSIONS Cannabis is a therapeutic option for treating the most complex patients with FMF.”

Cannabidiol attenuates seizures and EEG abnormalities in Angelman syndrome model mice.

 Image result for J Clin Invest.“Angelman syndrome (AS) is a neurodevelopmental disorder characterized by intellectual disability, lack of speech, ataxia, EEG abnormalities, and epilepsy. Seizures in AS individuals are common, debilitating, and often drug-resistant. Therefore, there is an unmet need for better treatment options.

Cannabidiol (CBD), a major phytocannabinoid constituent of cannabis, has antiseizure activity and behavioral benefits in preclinical and clinical studies for some disorders associated with epilepsy, suggesting that the same could be true for AS.

Here we show that acute CBD (100 mg/kg) attenuated hyperthermia- and acoustically-induced seizures in a mouse model of AS. However, neither acute CBD nor a two-weeklong course of CBD administered immediately after a kindling protocol could halt the pro-epileptogenic plasticity observed in AS model mice.

CBD had a dose-dependent sedative effect, but did not have an impact on motor performance. CBD abrogated the enhanced intracortical local field potential power, including delta and theta rhythms observed in AS model mice, indicating that CBD administration could also help normalize the EEG deficits observed in individuals with AS.

Our results provide critical preclinical evidence supporting CBD treatment of seizures and alleviation of EEG abnormalities in AS, and will thus help guide the rational development of CBD as an AS treatment.”

Cannabidiol improves metabolic dysfunction in middle-aged diabetic rats submitted to a chronic cerebral hypoperfusion.

Chemico-Biological Interactions“Cannabidiol (CBD), a compound obtained from Cannabis sativa, has wide range of therapeutic properties, including mitigation of diabetes and neurodegeneration.

Cerebral ischemia and consequent learning disabilities are aggravated in elderly diabetic subjects. However, there are no studies showing the effect of CBD treatment in elderly diabetes patients suffering cerebral ischemia.

The present work tested the hypothesis that CBD treatment improves metabolic dysfunctions in middle-aged diabetic rats submitted to chronic cerebral hypoperfusion.

CBD may be used as therapeutic tool to protect metabolism against injuries from diabetes aggravated by cerebral ischemia.”

“CBD reduced hyperglycemia of middle-aged diabetic rats with CCH. CBD increased insulin secretion and decreased AGEs levels. CBD reduced fructosamine, LDL, HDL, triglycerides and total cholesterol levels. CBD presented hepatoprotective effect. CBD could mitigate neurodegeneration caused by DM associated to cerebral ischemia.”

Combination of Cannabinoids, Δ9- Tetrahydrocannabinol and Cannabidiol, Ameliorates Experimental Multiple Sclerosis by Suppressing Neuroinflammation Through Regulation of miRNA-Mediated Signaling Pathways.

 Image result for frontiers in immunology“Multiple sclerosis (MS) is a chronic and disabling disorder of the central nervous system (CNS) characterized by neuroinflammation leading to demyelination.

Recently a combination of Δ9-tetrahydrocannabinol (THC) and Cannabidiol (CBD) extracted from Cannabis has been approved in many parts of the world to treat MS-related spasticity. THC+CBD combination was also shown to suppresses neuroinflammation, although the mechanisms remain to be further elucidated.

In the current study, we demonstrate that THC+CBD combination therapy (10 mg/kg each) but not THC or CBD alone, attenuates murine experimental autoimmune encephalomyelitis (EAE) by reducing neuroinflammation and suppression of Th17 and Th1 cells.

Collectively, this study suggests that combination of THC+CBD suppresses neuroinflammation and attenuates clinical EAE development and that this effect is associated with changes in miRNA profile in brain-infiltrating cells.”

Real world experience of patients with amyotrophic lateral sclerosis (ALS) in the treatment of spasticity using tetrahydrocannabinol:cannabidiol (THC:CBD).

Image result for bmc neurology“Treatment of spasticity poses a major challenge in amyotrophic lateral sclerosis (ALS) patient management.

Delta-9-tetrahydrocannabinol (THC):cannabidiol (CBD) oromucosal spray (THC:CBD), approved for the treatment of spasticity in multiple sclerosis, serves as a complementary off-label treatment option in ALS-related spasticity.

The mean dose THC:CBD were 5.5 daily actuations (range < 1 to 20). Three subgroups of patients were identified: 1) high-dose daily use (≥ 7 daily actuations, 34%, n = 11), 2) low-dose daily use (< 7 daily actuations, 50%, n = 16), 3) infrequent use (< 1 daily actuation, 16%, n = 5). Overall NPS was + 4.9 (values above 0 express a positive recommendation to fellow patients). Remarkably, patients with moderate to severe spasticity (NRS ≥ 4) reported a high recommendation rate (NPS: + 29) in contrast to patients with mild spasticity (NRS < 4; NPS: - 44). For the three main domains of TSQM-9 high mean satisfaction levels were found (maximum value 100): effectiveness 70.5 (±22.3), convenience 76.6 (±23.3) and global satisfaction 75.0 (±24.7).

CONCLUSION:

THC:CBD is used in a wide dose range suggesting that the drug was applied on the basis of individual patients’ needs and preferences. Contributing to this notion, moderate to severe spasticity was associated with an elevated number of daily THC:CBD actuations and stronger recommendation rate (NPS) as compared to patients with mild spasticity. Overall, treatment satisfaction (TSQM-9) was high. The results suggest that THC:CBD may serve as a valuable addition in the spectrum of symptomatic therapy in ALS. However, prospective studies and head-to-head comparisons to other spasticity medications are of interest to further explore the effectiveness of THC:CBD in the management of spasticity, and other ALS-related symptoms.”

“Overall, patients reported outcomes as assessed by TSQM-9 revealed a high treatment satisfaction with THC:CBD. The results of our study suggest that THC:CBD may serve as an important addition to the spectrum of treatment options of spasticity in ALS.”

The “entourage effect”: Terpenes coupled with cannabinoids for the treatment of mood disorders and anxiety disorders.

“Mood disorders are the most prevalent mental conditions encountered in psychiatric practice. Numerous patients suffering from mood disorders present with treatment-resistant forms of depression, co-morbid anxiety, other psychiatric disorders and bipolar disorders.

Standardized essential oils (such as that of Lavender officinalis) have been shown to exert clinical efficacy in treating anxiety disorders. As endocannabinoids are suggested to play an important role in major depression, generalized anxiety and bipolar disorders, Cannabis sativa, was suggested for their treatment.

The endocannabinoid system is widely distributed throughout the body including the brain, modulating many functions. It is involved in mood and related disorders, and its activity may be modified by exogenous cannabinoids.

CB1 and CB2 receptors primarily serve as the binding sites for endocannabinoids as well as for phytocannabinoids, produced by cannabis inflorescences. However, ‘cannabis’ is not a single compound product but is known for its complicated molecular profile, producing a plethora of phytocannabinoids alongside a vast array of terpenes.

Thus, the “entourage effect” is the suggested positive contribution derived from the addition of terpenes to cannabinoids. Here we review the literature on the effects of cannabinoids and discuss the possibility of enhancing cannabinoid activity on psychiatric symptoms by the addition of terpenes and terpenoids.

Possible underlying mechanisms for the anti-depressant and anxiolytic effects are reviewed. These natural products may be an important potential source for new medications for the treatment of mood and anxiety disorders.”

The Effectiveness of Cannabinoids in the Treatment of Posttraumatic Stress Disorder (PTSD): A Systematic Review.

Publication CoverPosttraumatic stress disorder (PTSD) is a potentially debilitating mental health problem.

There has been a recent surge of interest regarding the use of cannabinoids in the treatment of PTSD.

We therefore sought to systematically review and assess the quality of the clinical evidence of the effectiveness of cannabinoids for the treatment of PTSD.

We found that cannabinoids may decrease PTSD symptomology, in particular sleep disturbances and nightmares.

Evidence that cannabinoids may help reduce global PTSD symptoms, sleep disturbances, and nightmares indicates that future well-controlled, randomized, double-blind clinical trials are highly warranted.”

[Dronabinol in geriatric pain and palliative care patients : A retrospective evaluation of statutory-health-insurance-covered outpatient medical treatment].

 

“Geriatric patients often suffer from a long history of pain and have a limited life expectancy.

Cannabinoid receptor agonists like dronabinol may be an effective, low-risk treatment option for geriatric patients with chronic pain.

OBJECTIVES:

The effectiveness and side effects of dronabinol therapy in geriatric patients are analyzed. The effects of the approval requirement are presented.

RESULTS:

By using dronabinol, 21 of the 40 geriatric patients (52.5%) achieved pain relief of more than 30%, 10% of the patients of more than 50%. On average, about four symptoms or side effects related to previous treatment were positively influenced. 26% of patients reported side effects. The rejection rates on the part of the health insurances were 38.7% (group A) and 10.3% (group B).

CONCLUSIONS:

This study is one of the few analyses of the use of Dronabinol in geriatric patients. We show that cannabis-based drugs (in this case dronabinol) are an effective, low-risk treatment option that should be considered early in therapy. Regarding the indication spectrum, further clinical studies and an approval-free test phase are necessary.”

Cannabis-based treatments as an alternative remedy for epilepsy

Integrative Medicine Research“Much of the initial reports for cannabis use in seizure control centered on the compound 9-Δ-tetrahydrocannabinol (THC). However, due to the psychoactive properties of THC potential utility was somewhat limited and recent research has focused on non-psychoactive compounds such as cannabidiol (CBD).

The anti-seizure effects of CBD may come from mechanisms such as functional agonism or antagonism at several 7-transmembrane receptors, ion channels, and neurotransmitter transporters.

Recently, another compound that also is without psychoactive effects known as CBDV has also shown anti-seizure properties both in vivo and in vitro.

Many reports exist on illicit cannabis use through the smoking of marijuana by patients as a self-treatment.

Cannabis and cannabis-based treatments offer promising alternatives to traditional antiepileptic drugs (AEDs).

Due to the unfortunate fact that many patients suffer from Drug-resistant epilepsy (DRE), cannabis-based treatments have great value.

Cannabis-based treatments offer some patients with DRE a great remedy for their condition with limited side effects.

This option may prevent some patients with DRE from needing to consider more invasive options such as surgical interventions. In case studies, open label studies, and RCTs, one can see drastic improvements in the frequency of seizures in patients with certain forms of epilepsy.

It is imperative to continue research into cannabis as a potential primary treatment for epilepsy, particularly those with DRE, to help improve quality of life for millions of people suffering from epilepsy.”

Cannabinoids Δ9-tetrahydrocannabinol and cannabidiol may be effective against methamphetamine induced mitochondrial dysfunction and inflammation by modulation of Toll-like type-4(Toll-like 4) receptors and NF-κB signaling.

Medical Hypotheses“The neurodegeneration, neuro-inflammation and mitochondrial dysfunction which occur by methamphetamine (METH) abuse or administration are serious and motivation therapeutic approaches for inhibition of these types of neurodegeneration. As we know, METH through Toll-like receptors (TLRs), specially type 4, and NF-κB signaling pathway causes neuro-inflammation and mitochondrial dysfunction.

Neuroprotective approach for management of METH-induced neurodegeneration, inflammation and mitochondrial dysfunction, through a novel neuroprotective agent is continuously being superior to any kind of other therapeutic strategy. Therefore, the clarification, introduction and development of efficacious novel neuroprotective agent are demanded. During recent years, using new neuroprotective agent with therapeutic probability for treatment of METH-induced neuro-inflammation and mitochondrial dysfunction has been astoundingly increased.

Previous studies have stated the neuroprotective and anti-inflammatory roles of cannabinoid derivate such as cannabidiol (CBD) and delta-9-tetrahydrocannabinol (Δ9-THC) in multiple neurodegenerative events and diseases.

According to literature cannabinoid derivate, by inhibition of TLR4 and activation of NF-κB signaling pathway, exerts their anti-inflammatory and neuroprotective effects and cause mitochondrial biogenesis. Thus we hypothesized that by using cannabinoids in METH dependent subject it would provide neuroprotection against METH-induced neurodegeneration, neuro-inflammation and mitochondrial dysfunction and probably can manage sequels of METH-induced neurochemical abuses via modulation of TLR4/NF-κB signaling pathway.

In this article, we tried to discuss our hypothesis regarding the possible role of CBD and Δ9-THC, as a potent neuroprotective and anti-inflammatory agents, in inhibition or treatment of METH-induced neurodegeneration, neuro-inflammation and mitochondrial dysfunction through its effects on TLR4/NF-κB signaling pathway.”
