Cytokine & Growth Factor Reviews

“Cannabidiol to decrease SARS-CoV-2 associated inflammation.

Cannabidiol (CBD) is a phytocannabinoid with various clinical applications and has proven efficacy for certain medical conditions, along with a favorable safety and tolerability profile.

Cannabinoids can suppress immune activation and inflammatory cytokine production, suggesting their potential for tempering excessive inflammation.

Therefore, as SARS-CoV2 induces significant damage through pro-inflammatory cytokine storm mediated by macrophages and other immune cells and based on the fact that CBD has broad anti-inflammatory properties, CBD might represent as a potential anti-inflammatory therapeutic approach against SARS-CoV2-induced inflammation.

As CBD is already a therapeutic agent used in clinical medicine and has a favorable safety profile, the results of in vitro and animal model proof-of-concept studies would provide the necessary supporting evidence required before embarking on costly and labor-intensive clinical trials.”

Harefuah” - IMA - Israel Medicine Association“Medical cannabis (MC) is becoming more and more popular among patients with chronic pain syndromes.

In this study we evaluated the characteristics of MC use among patients with fibromyalgia.

MC is an effective treatment for fibromyalgia, with nearly zero % withdrawal from this treatment.

MC treatment enabled nearly half of the patients to discontinue any treatment for fibromyalgia and all participants recommended MC treatment for their loved ones in case they develop severe fibromyalgia.”

“Historical relevance: Cannabis sativa L. (C. sativa) is a plant whose use as a therapeutic agent shares its origins with the first Far East’s human societies. Cannabis has been used not only for recreational purposes, but as a food to obtain textile fibers, to produce hemp paper, to treat many physical and mental disorders.

This review aims to provide a complete assessment of the deep knowledge of the cannabis psychoactive effects and medicinal properties in the course of history covering i.) the empirical use of the seeds and the inflorescences to treat many physical ailments by the ancient Oriental physicians ii.) the current use of cannabis as a therapeutic agent after the discovery of its key psychoactive constituent and the human endogenous endocannabinoid system.

Results and conclusion: Through a detailed analysis of the available resources about the origins of C. sativa we found that its use by ancient civilizations as a source of food and textile fibers dates back over 10,000 years, while its therapeutic applications have been improved over the centuries, from the ancient East medicine of the 2nd and 1st millennium B.C. to the more recent introduction in the Western world after the 1st century A.D. In the 20th and 21th centuries, Cannabis and its derivatives have been considered as a menace and banned throughout the world, but nowadays they are still the most widely consumed illicit drugs all over the world. Its legalization in some jurisdictions has been accompanied by new lines of research to investigate its possible applications for medical and therapeutic purposes.”

Trends in Plant Science: Special issue: Specifi...“Cannabis has been used as a medicine for millennia.

Crude extracts of cannabis inflorescence contain numerous phytomolecules, including phytocannabinoids, terpenes, and flavonoids. Combinations of phytomolecules have been recently established as superior to the use of single molecules in medical treatment owing to the ‘entourage effect’.

Two types of entourage effects are defined: ‘intra-entourage’, resulting from interactions among phytocannabinoids or terpenes, and ‘inter-entourage’, attributed to interactions between phytocannabinoids and terpenes. It is suggested that the phytomolecule assemblages found in cannabis chemovars today derive from selective breeding during ancient cultivation.

We propose that the current cannabis chemotaxonomy should be redefined according to chemical content and medicinal activity. In parallel, combinations of phytomolecules that exhibit entourage activity should be explored further for future drug development.”

Current Issue Cover Image“Opioid prescriptions and abuse remain a significant national concern.

Cannabinoids offer a potentially attractive nonopioid analgesic option for orthopaedic patients, and 32 US states have passed medical cannabis laws (MCLs), legalizing patient access to cannabinoids.

We examine the association between implementation of state cannabis laws and prescribing patterns for opioids by orthopaedic surgeons in Medicare Part D patients between 2013 and 2017.

RESULTS:

State MCLs were associated with a statistically significant reduction in aggregate opioid prescribing of 144,000 daily doses (19.7% reduction) annually (95% confidence interval [CI], -0.535 to -0.024 million; P < 0.01). States with MCLs allowing access to in-state dispensaries had a statistically significant reduction in total opioid prescriptions of 96,000 daily doses (13.1%) annually (95% CI, -0.165 to -0.026 million; P < 0.01). Specifically, MCLs were associated with a statistically significant reduction of 72,000 daily doses of hydrocodone annually (95% CI, -0.164 to -0.019 million; P < 0.01). No significant association between recreational marijuana legalization and opioid prescribing was found.

CONCLUSION:

Orthopaedic surgeons are among the highest prescribers of opioids, highlighting the importance of providing nonopioid analgesic alternatives in efforts to reduce opioid use in the patient cohort. This study is the first to examine the association between implementation of state cannabis laws and prescribing patterns for opioids by orthopaedic surgeons in Medicare Part D patients.”

A Case of Mutism Subsequent to Cocaine Abuse - Journal of ...“Four states have legalized medical cannabis for the purpose of treating opioid use disorder. It is unclear whether cannabinoids improve or exacerbate opioid withdrawal. A more thorough examination of cannabis and its impact on specific symptoms of opioid withdrawal is warranted.

METHOD:

Two hundred individuals recruited through Amazon Mechanical Turk with past month opioid and cannabis use and experience of opioid withdrawal completed the survey. Participants indicated which opioid withdrawal symptoms improved or worsened with cannabis use and indicated the severity of their opioid withdrawal on days with and without cannabis.

RESULTS:

62.5% (n = 125) of 200 participants had used cannabis to treat withdrawal. Participants most frequently indicated that cannabis improved: anxiety, tremors, and trouble sleeping. A minority of participants (6.0%, n = 12) indicated cannabis worsened opioid withdrawal, specifically symptoms of yawning, teary eyes, and runny nose. Across all symptoms, more participants indicated that symptoms improved with cannabis compared to those that indicated symptoms worsened with cannabis. Women reported greater relief from withdrawal with cannabis use than men.

DISCUSSION:

These results show that cannabis may improve opioid withdrawal symptoms and that the size of the effect is clinically meaningful. It is important to note that symptoms are exacerbated with cannabis in only a minority of individuals. Prospectively designed studies examining the impact of cannabis and cannabinoids on opioid withdrawal are warranted.”

Journal of Pharmaceutical and Biomedical Analysis“Cannabis-based medications are being increasingly used for the treatment of different clinical conditions.

Among all galenic formulations, olive oil extracts from medical Cannabis are the most prescribed ones for their easy preparation and usage. A great variety of methods have been described so far for the extraction of medical Cannabis oils to reach a high yield of Δ9-tetrahydrocannabinol (Δ9-THC), but poor attention has been paid to the preservation of the terpene fraction from the plant, which may contribute to the overall bioactivity of the extracts.

In this context, the present study was aimed at the chemical characterization of different medical Cannabis oils prepared by following both innovative and existing extraction protocols, with particular attention to cannabinoids and terpenes, in order to set up a suitable method to obtain an extract rich in these chemical classes. In particular, six different extraction procedures were followed, based on different techniques, of which all but one included a decarboxylation of the plant material.

The profile of cannabinoids was studied in detail by means of HPLC-ESI-MS/MS, while terpenes were characterized by means both GC-MS and GC-FID techniques coupled with solid-phase microextraction operated in the head-space mode (HS-SPME). An innovative method that is based on the extraction of the oil by dynamic maceration at room temperature from plant inflorescences, which were partially decarboxylated in a closed system at a moderate temperature and partially pre-extracted with ethanol, produced similar yields of bioactive compounds as that obtained by using a microwave-assisted distillation of the essential oil from the plant material, in combination with a maceration extraction of the oil from the residue.

Both these new methods provided a higher efficiency over already existing extraction procedures of medical Cannabis oils and they can be applied to obtain a product with a high therapeutic value.”

 Current Opinion in Supportive and Palliative Care | Apps | 148Apps“An increasing number of patients are turning to cannabis and cannabinoids for management of their palliative and nonpalliative cancer pain and other cancer-related symptoms.

Canadians have a legal framework for access to medical cannabis, which provides a unique perspective in a setting lacking robust clinical evidence. This review seeks to delineate the role of cannabis and cannabinoids in cancer pain management and offers insight into the Canadian practice.

RECENT FINDINGS:

A cohort study using nabiximols on advanced cancer pain in patients already optimized on opioids, over 3 weeks, demonstrated improved average pain score. A large observational study of cancer patients using cannabis over 6 months demonstrated a decreased number of patients with severe pain and decreased opioid use, whereas the number of patients reporting good quality of life increased.

SUMMARY:

Good preclinical animal data and a large body of observational evidence point to the potential efficacy of cannabinoids for cancer pain management. However, there are relatively weak data pointing to clinical efficacy from clinical trial data to date. In Canada, the burgeoning cannabis industry has driven the population to embrace a medicine before clinical evidence. There remains a need for high-quality randomized controlled trials to properly assess the effectiveness and safety of medical cannabis, compared with placebo and standard treatments for cancer-related symptoms.”

logo“Despite the increasing prevalence and acceptance of the medical cannabis use among the general public, the evidence required by physicians to use cannabis as a treatment is generally lacking. Research on the health effects of cannabis and cannabinoids has been limited worldwide, leaving patients, health care professionals, and policymakers without the evidence they need to make sound decisions regarding the use of cannabis and cannabinoids.

This case study outlines an intervention that involved a patient integrating medical cannabis into her treatment to better manage a generalized anxiety disorder and the debilitating symptoms of vertigo. This case demonstrates how the patient drastically improved her quality of life and reinforces the need for more rigorous testing on the use of medical cannabis to support patients and better manage the symptoms associated with their medical conditions.”
