Association of cannabis use during pregnancy with severe acute respiratory syndrome coronavirus 2 infection: a retrospective cohort study

/by

Endocannabinoid (eCB) levels fluctuate in inflammatory conditions and as such may take part in endometriosis-associated pain or even in endometriosis pathogenesis. In this case–control (23 cases and 19 controls) study, targeted lipids were measured in the serum and peritoneal fluid collected during laparoscopy. Endometriosis was confirmed histologically. Dysmenorrhea, abdominal pain, and dyspareunia were assessed using the Numeric Rating Scale for pain. Steroids, eCBs, and related lipids were quantified by liquid chromatography-tandem mass spectrometry (LC-MS/MS).

Efficacy and usability of a cannabidiol-infused tampon for the relief of primary dysmenorrhea

/by

This study aimed to assess efficacy and usability of Cannabidiol (CBD) infused tampons for the relief of primary dysmenorrhea, a condition affecting 50–95% assigned female at birth. While primary dysmenorrhea affects a significant percentage of females, there remains a notable absence of specialized medications or devices to alleviate the intense pain that hinders daily activities. We have developed a CBD-infused tampon, lubricated for comfort and ease, recognising the potential benefits of cannabinoids in pain management.

Cannabidiol as a potential novel treatment for endometriosis by its anti-inflammatory, antioxidative and antiangiogenic effects in an experimental rat model

/by

Endometrial implants were surgically induced in 36 female Wistar albino rats. After confirmation of endometriotic foci, the rats were randomized into four groups. In the leuprolide acetate group, rats were given a single 1 mg/kg s.c. leuprolide acetate injection. The other groups were 5 mg/kg CBD (CBD5), saline solution and 20 mg/kg CBD (CBD20); daily i.p. injections were administered for 7 days. After 21 days, the rats were euthanised, and total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-α) measurements in blood and peritoneal fluid samples, and immunohistochemical staining for TNF-α, IL-6 and vascular endothelial growth factor (VEGF) of endometriotic tissues were evaluated.

Is it the Ideal Time to Start Prescribing Cannabis Derivatives to Treat Endometriosis-associated Pain?

/by

Endometriosis affects 5%-10% of women of reproductive age and is often associated with painful symptoms like dysmenorrhea, dyschezia, dyspareunia, and even non cyclical pain. The disease is diagnosed in at least 20% of women with dysmenorrhea and/or non-menstrual pelvic pain, reaching a prevalence of 50% pain among adolescents. There is an alignment among international societies3,4 that the pre- sumed diagnosis of this disease is enough to start clinical treatment. Moreover, there seems to be a consensus that first-line treatment should be hormonal contraceptives since the efficacy is similar to that of surgery but with lower complication rates and costs. However, these drugs are
effective in only approximately two-thirds of patients, have limited long-term efficacy and may occasionally lead to undesirable side effects. Additionally, there are serious limitations in the interpretation of clinical trials.

Can cannabidiol (CBD) be used in the treatment of endometriosis by its anti-inflammatory, antioxidative, and anti-angiogenic effects? Endometrial implants were surgically induced in 36 female Wistar-Albino rats. After confirmation of endometriotic foci, the rats were randomized into four groups. In leuprolide acetate (LA) group, rats were given a single 1mg/kg subcutaneous LA injection. Other groups were 5 mg/kg CBD (CBD5), saline solution (SS), and 20 mg/kg CBD (CBD20) and daily intra-peritoneal injections were applied for seven days. After 21 days, the rats were sacrificed, and total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) measurements in blood and peritoneal fluid samples, and immunohistochemical staining for TNF-α, IL-6 and vascular endothelial growth factor (VEGF) of endometriotic tissues were evaluated.

Role of the endocannabinoid system in the pathophysiology of endometriosis and therapeutic implications

/by

Endometriosis patients experience debilitating chronic pain, and the first-line treatment is ineffective at managing symptoms. Although surgical removal of the lesions provides temporary relief, more than 50% of the patients experience disease recurrence. Despite being a leading cause of hysterectomy, endometriosis lacks satisfactory treatments and a cure. Another challenge is the poor understanding of disease pathophysiology which adds to the delays in diagnosis and overall compromised quality of life. Endometriosis patients are in dire need of an effective therapeutic strategy that is both economical and effective in managing symptoms, while fertility is unaffected. Endocannabinoids and phytocannabinoids possess anti-inflammatory, anti-nociceptive, and anti-proliferative properties that may prove beneficial for endometriosis management, given that inflammation, vascularization, and pain are hallmark features of endometriosis.

Many cannabinoids display promising non-hallucinogenic bioactivities that are determined by the variable nature of the side chain and prenyl group defined by the enzymes involved in their synthesis.
