Use of complementary therapies for chronic pain management in patients with reported Ehlers-Danlos syndrome or hypermobility spectrum disorders

American Journal of Medical Genetics Part A“Ehlers-Danlos Syndromes (EDS) and related Hypermobility Spectrum Disorders (HSD) are debilitating connective tissue disorders that feature a prominent pain component for which there are limited therapeutic options for pain management.

Consequently, many patients try various non-prescribed treatments, including complementary and alternative therapies that have not been well studied in the EDS/HSD patient population. We surveyed over 500 individuals through the EDS Society who reported having been diagnosed with EDS or HSD to ascertain what complementary and alternative therapies were used and their reported effectiveness in alleviating pain and improving quality of life.

Specifically, we focused on the use of traditional Chinese therapies, herbal medications, and marijuana.

The most commonly reported therapies, used by 70-92% of participants, were non-steroidal anti-inflammatory drugs, acetaminophen, opioids, and physical therapy.

Therapies rated by participants as most efficacious were opioids, physical therapy, and marijuana with 10-24% of those using these therapies rating them as extremely helpful.

Patient-initiated complementary therapy use in EDS/HSD patients is widespread at 56%. Complementary therapies were largely utilized by EDS/HSD patients with higher reported pain levels. Providers caring for EDS/HSD patients should be aware of these data showing broad usage of predominantly non-prescribed therapies and be prepared to consider such usage in working collaboratively with these patients to develop comprehensive treatment plans to manage their chronic pain complications.”

Treating pain related to Ehlers-Danlos syndrome with medical cannabis

BMJ Journals“We present the case of an 18-year-old woman who suffered from complications of Ehlers-Danlos syndrome (EDS). Her pain was poorly controlled despite being on a myriad of analgesic medications at the time.

On initiating cannabinoid-based treatment, her pain was drastically reduced, immediately enhancing the patient’s quality of life. As the patient continued to self-administer, she was able to eliminate her opioid requirement.

Considering the recent legalisation, we underline the need for physicians to be educated regarding the use of cannabinoids. In this case, specifically for chronic pain stemming from hypermobile EDS. Furthermore, we review the various impediments preventing ease of access to this potentially beneficial treatment.”

Therapeutic Attributes of Endocannabinoid System against Neuro-Inflammatory Autoimmune Disorders

molecules-logo“In humans, various sites like cannabinoid receptors (CBR) having a binding affinity with cannabinoids are distributed on the surface of different cell types, where endocannabinoids (ECs) and derivatives of fatty acid can bind. The binding of these substance(s) triggers the activation of specific receptors required for various physiological functions, including pain sensation, memory, and appetite.

The ECs and CBR perform multiple functions via the cannabinoid receptor 1 (CB1); cannabinoid receptor 2 (CB2), having a key effect in restraining neurotransmitters and the arrangement of cytokines. The role of cannabinoids in the immune system is illustrated because of their immunosuppressive characteristics. These characteristics include inhibition of leucocyte proliferation, T cells apoptosis, and induction of macrophages along with reduced pro-inflammatory cytokines secretion.

The review seeks to discuss the functional relationship between the endocannabinoid system (ECS) and anti-tumor characteristics of cannabinoids in various cancers.

The therapeutic potential of cannabinoids for cancer-both in vivo and in vitro clinical trials-has also been highlighted and reported to be effective in mice models in arthritis for the inflammation reduction, neuropathic pain, positive effect in multiple sclerosis and type-1 diabetes mellitus, and found beneficial for treating in various cancers.

In human models, such studies are limited; thereby, further research is indispensable in this field to get a conclusive outcome. Therefore, in autoimmune disorders, therapeutic cannabinoids can serve as promising immunosuppressive and anti-fibrotic agents.”

Epigenetic Regulation of Cannabinoid-Mediated Attenuation of Inflammation and Its Impact on the Use of Cannabinoids to Treat Autoimmune Diseases

ijms-logo“Chronic inflammation is considered to be a silent killer because it is the underlying cause of a wide range of clinical disorders, from cardiovascular to neurological diseases, and from cancer to obesity. In addition, there are over 80 different types of debilitating autoimmune diseases for which there are no cure. Currently, the drugs that are available to suppress chronic inflammation are either ineffective or overtly suppress the inflammation, thereby causing increased susceptibility to infections and cancer. Thus, the development of a new class of drugs that can suppress chronic inflammation is imperative.

Cannabinoids are a group of compounds produced in the body (endocannabinoids) or found in cannabis (phytocannabinoids) that act through cannabinoid receptors and various other receptors expressed widely in the brain and immune system. In the last decade, cannabinoids have been well established experimentally to mediate anti-inflammatory properties. Research has shown that they suppress inflammation through multiple pathways, including apoptosis and inducing immunosuppressive T regulatory cells (Tregs) and myeloid-derived suppressor cells (MDSCs).

Interestingly, cannabinoids also mediate epigenetic alterations in genes that regulate inflammation. In the current review, we highlight how the epigenetic modulations caused by cannabinoids lead to the suppression of inflammation and help identify novel pathways that can be used to target autoimmune diseases.”

Pros and Cons of the Cannabinoid System in Cancer: Focus on Hematological Malignancies

molecules-logo“The endocannabinoid system (ECS) is a composite cell-signaling system that allows endogenous cannabinoid ligands to control cell functions through the interaction with cannabinoid receptors. Modifications of the ECS might contribute to the pathogenesis of different diseases, including cancers. However, the use of these compounds as antitumor agents remains debatable.

Pre-clinical experimental studies have shown that cannabinoids (CBs) might be effective for the treatment of hematological malignancies, such as leukemia and lymphoma.

Specifically, CBs may activate programmed cell death mechanisms, thus blocking cancer cell growth, and may modulate both autophagy and angiogenesis. Therefore, CBs may have significant anti-tumor effects in hematologic diseases and may synergistically act with chemotherapeutic agents, possibly also reducing chemoresistance.

Moreover, targeting ECS might be considered as a novel approach for the management of graft versus host disease, thus reducing some symptoms such as anorexia, cachexia, fatigue, anxiety, depression, and neuropathic pain. The aim of the present review is to collect the state of the art of CBs effects on hematological tumors, thus focusing on the essential topics that might be useful before moving into the clinical practice.”

Medical marijuana utilization in gynecologic cancer patients

Gynecologic Oncology Reports“Medical marijuana (MM) use is common among cancer patients, but relatively little is known about the usage patterns and efficacy of MM used by gynecologic cancer patients.

Methods: Demographic and clinical data were collected for gynecologic cancer patients prescribed MM between May 2016 and February 2019. The electronic medical record was used to query formulation prescribed, usage patterns, length of use, symptom relief, and side effect profile. Descriptive statistics were calculated.

Results: Of 45 gynecologic cancer patients prescribed MM, 89% were receiving chemotherapy; 56% were undergoing primary treatment. MM was used for a median of 5.2 months (range 0.6-25.4). Over 70% of patients reported improvement in nausea/vomiting, compared to 36% of patients using MM for pain relief (p = 0.02). Of 41 patients with follow-up information, 71% found MM improved at least one symptom.

Conclusions: Among a small sample of gynecologic cancer patients prescribed MM for symptom management, self-reported follow-up indicated symptom relief for the majority of patients and minimal therapy-related side effects. This data can prove useful for counseling gynecologic cancer patients on the efficacy and side effects of MM.”

https://pubmed.ncbi.nlm.nih.gov/34258360/

“Among a small cohort of gynecologic cancer patients prescribed MM for symptom management, the majority reported improvement in at least one disease or treatment-related symptom and reported minimal side effects. Further larger prospective studies are needed to investigate specific formulations and indications in this patient population, but our data indicate that it is a safe and useful adjunct for symptom management among a diverse cohort of women with gynecologic cancer.”

An Observational, Longitudinal Study of Cognition in Medical Cannabis Patients over the Course of 12 Months of Treatment: Preliminary Results

Journal of the International Neuropsychological SocietyCannabis use has increased dramatically across the country; however, few studies have assessed the long-term impact of medical cannabis (MC) use on cognition. Studies examining recreational cannabis users generally report cognitive decrements, particularly in those with adolescent onset. As MC patients differ from recreational consumers in motives for use, product selection, and age of onset, we assessed cognitive and clinical measures in well-characterized MC patients over 1 year. Based on previous findings, we hypothesized MC patients would not show decrements and might instead demonstrate improvements in executive function over time.

Method: As part of an ongoing study, MC patients completed a baseline visit prior to initiating MC and evaluations following 3, 6, and 12 months of treatment. At each visit, patients completed a neurocognitive battery assessing executive function, verbal learning/memory, and clinical scales assessing mood, anxiety, and sleep. Exposure to delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) was also quantified.

Results: Relative to baseline, MC patients demonstrated significant improvements on measures of executive function and clinical state over the course of 12 months; verbal learning/memory performance generally remained stable. Improved cognitive performance was not correlated with MC use; however, clinical improvement was associated with higher CBD use. Analyses suggest cognitive improvements were associated with clinical improvement.

Conclusions: Study results extend previous pilot findings, indicating that MC patients may exhibit enhanced rather than impaired executive function over time. Future studies should examine distinctions between recreational and MC use to identify potential mechanisms related to cognitive changes and the role of clinical improvement.”

Spiritual Benefit from Cannabis

Publication Cover“Like many mind-altering plants, cannabis has been part of spiritual practices for thousands of years. It has deep roots in Hinduism, Islam, Rastafarianism, and indigenous traditions in Asia, Africa, and elsewhere. Yet almost no attention has been given to how contemporary adults employ it spiritually. A sample of 1087 participants (mean age = 38.9) completed an online survey assessing their use of cannabis and other substances, as well as spiritual and psychological characteristics. Spiritual benefit from cannabis was reported by 66.1% of the sample, and 5.5% reported it had sometimes been a spiritual hindrance. A MANOVA showed that those who reported spiritual benefit differed significantly from those who did not on several outcome variables, and a post hoc descriptive discriminant analysis revealed that expansiveness motivation, non-theistic daily spiritual experience, meditation frequency, and two mindfulness facets contributed most to differentiating the two groups. The majority of the sample (63%) was free of cannabis use disorder. Compared to disordered groups, the non-disordered group was significantly older and scored lower on experiential avoidance, psychological distress, and several motives for use. Results suggest that spiritual motives for cannabis use may be widespread. Implications for future research on spiritual use of cannabis are discussed.”

Marijuana Use and the Risk of Early Ischemic Stroke: The Stroke Prevention in Young Adults Study

Stroke logo“Few studies have examined the dose-response and temporal relationships between marijuana use and ischemic stroke while controlling for important confounders, including the amount of tobacco smoking. The purpose of our study was to address these knowledge gaps.

Results: After adjusting for other risk factors, including the amount of current tobacco smoking, marijuana use was not associated with ischemic stroke, regardless of the timing of use in relationship to the stroke, including ever use, use within 30 days, and use within 24 hours.

Conclusions: These analyses do not demonstrate an association between marijuana use and an increased risk of early-onset ischemic stroke, although statistical power was limited for assessing the association among very heavy users.”

Targeting the endocannabinoid system for management of HIV-associated neuropathic pain: A systematic review

IBRO Neuroscience Reports“Human immunodeficiency virus (HIV) infection and antiretroviral therapy can independently induce HIV-associated neuropathic pain (HIV-NP).

Smoked cannabis has been reported to improve pain measures in patients with neuropathic pain.

Two clinical trials demonstrated greater efficacy of smoked cannabis over placebo in alleviating HIV-NP.

The available preclinical results suggest that targeting the ECS for prevention and treatment of HIV-NP is a plausible therapeutic option.

Clinical evidence shows that smoked cannabis alleviates HIV-NP.”
