ABSTRACT

We characterized the frequency of diffusely abnormal white matter (DAWM) across a broad spectrum of multiple sclerosis (MS) participants. 35% of clinically isolated syndrome (CIS), 57% of relapsing remitting and 64% of secondary progressive MS participants demonstrated DAWM. CIS with DAWM had decreased cortical thickness, higher lesion load and a higher concentration of serum neurofilament light chain compared to CIS without DAWM. DAWM may be useful in identifying CIS patients with greater injury to their brains. Larger and longitudinal studies are warranted.

ABSTRACT

OBJECTIVE: The objective of this study was to characterize the use of cannabis-based products (CBPs) by multiple sclerosis (MS) patients who attend the University of British Columbia Hospital (UBCH) MS clinic. METHODS: All patients attending the UBCH MS clinic from January to March 2018 were invited to participate in an anonymous survey that included: patient demographics (sex, age and employment status), self-reported MS-specific data (subtype, disease duration, previous and current disease modifying therapies, symptomatic medications) and CBP use (formulation, frequency, perceived benefits/side-effects). A second cohort of retrospective patient data (CBP use, sex, age, disease subtype and Expanded Disability Status Scale) was extracted from the UBCH MS clinic electronic medical record (EMR). RESULTS: Of 600 surveys distributed, 188 were returned with completed CBP usage. CBP use was daily for 19% (n = 37), weekly for 6% (n = 11), monthly for 4% (n = 7), rarely for 21% (n = 39) and 50% (n = 94) never used. Of the CBP users (daily, weekly and monthly), CBP use included: oral (n = 43/55), smoked/vaporized (n = 42/55), topical (n = 14/55) and mucosal (n = 5/55). EMR data was available for 561 MS patients where cannabis use/non-use was documented. CBP users represented 19% (107/561). CONCLUSIONS: CBP use is common based on volunteer reporting, with approximately one out of four patients who attend the UBCH MS clinic using CBPs.
