Palliative Care Aspects in Multiple Sclerosis

CONTEXT

Multiple sclerosis (MS) is an inflammatory, chronic, demyelinating, and neurodegenerative disorder of central nervous system, determined by an auto-immune dysfunction. Severe disability generally occurs in patients with progressive forms of MS that typically develop either after an earlier relapsing phase or less commonly from disease onset. Despite advances in research to slow the progression of MS, this condition remains a life-limiting disease with symptoms impacting negatively the lives of patients and caregivers.

OBJECTIVES

To analyze the difefrent aspects of palliative cae in patients with MS.

METHODS

To analyse selected literature assessing several palliative care aspects in patients with MS.

RESULTS

People with MS have complex symptoms and different needs. These demands include how to deal with the burden of physical disability, how to organise daily life, restructuring social roles in the family and at work, keeping self-sufficiency in personal care, and preserving personal identity and community roles.

CONCLUSION

An early palliative care approach aims to improve the palliative care skills and competencies of health professionals caring for the patients since the early stage of disease, including those who are actively undergoing disease-targeted therapies, rather than merely providing end-of-life care.

CBD and THC in Special Populations: Pharmacokinetics and Drug-Drug Interactions

Cannabinoid use has surged in the past decade, with a growing interest in expanding cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC) applications into special populations. Consequently, the increased use of CBD and THC raises the risk of drug-drug interactions (DDIs). Nevertheless, DDIs for cannabinoids, especially in special populations, remain inadequately investigated. While some clinical trials have explored DDIs between therapeutic drugs like antiepileptic drugs and CBD/THC, more potential interactions remain to be examined. This review summarizes the published studies on CBD and THC-drug interactions, outlines the mechanisms involved, discusses the physiological considerations in pharmacokinetics (PK) and DDI studies in special populations (including pregnant and lactating women, pediatrics, older adults, patients with hepatic or renal impairments, and others), and presents modeling approaches that can describe the DDIs associated with CBD and THC in special populations. The PK of CBD and THC in special populations remain poorly characterized, with limited studies investigating DDIs involving CBD/THC in these populations. Therefore, it is critical to evaluate potential DDIs between CBD/THC and medications that are commonly used in special populations. Modeling approaches can aid in understanding these interactions.
