Summary

The cannabinoid has benefits in many aspects but the evidence of the effect of cannabinoids in humans with SSc is limited. We, therefore, would like to investigate the efficacy of cannabinoids on the appetite, sleep efficiency, quality of life, pain, and critical cytokine level in SSc compared with placebo in SSc patients and the adverse events associated with cannabinoids in those patients.

Detailed description

Systemic sclerosis (SSc) is a connective tissue disease for which skin tightness is the hallmark. The disease is classified into 2 major subsets: limited cutaneous systemic sclerosis (lcSSc) and diffuse cutaneous systemic sclerosis (dcSSc) depending on the extent of skin tightness. Not only the skin tightness but also the internal organs such as the musculoskeletal, kidneys, lungs, heart, and intestines can be involved and associated with a poor outcome. Malnutrition and/or weight loss is a complications in SSc. The complication is possibly related to gastrointestinal involvement, inflammation, immunosuppressant agents, or mood disturbance which can affect the food appetite or eating behavior. As well as sleep quality, sleep disturbance has been reported in SSc patients and the associated factor of sleep disturbance in those patients was gastrointestinal involvement, particularly gastroesophageal reflux disease, the severity of pain, and depressed mood. The cannabinoid is an agent which affects appetite, pain, and sleep quality as mentioned above, hence it would improve the appetite, get a high sleep quality and reduce pain associated with musculoskeletal involvement in SSc patients. Although cannabinoid has benefit in many aspects, they also resulted in serious adverse events after cannabinoid inhalation, including ischemic stroke related to vasospasm of the cerebral vessel, high cardiac output, cardiac arrhythmias, blood pressure fluctuation, and respiratory tract infection. Acute toxicity has been reported and depended on unit dose, tolerance, and route of cannabinoid use. Cannabis also influenced brain function including memory, and cognitive function, and expanded the risk for psychosis in those who had prolonged use. The symptoms of central nervous system (CNS) toxicity include euphoria, panic, agitation, mood alterations, alteration of perception, loss of social inhibition, muscle incoordination, myoclonic jerking, ataxia, slurred speech, and risk of the suicidal idea. In addition, prolonged high doses of cannabis use can lead to the development of cannabinoid hyperemesis syndrome caused by cyclic hyperemesis, finally resulting in electrolyte disturbances and impaired kidney function. Because the evidence of the effect of cannabinoids in humans with SSc is limited. We, therefore, would like to investigate the efficacy of cannabinoids on the appetite, sleep efficiency, quality of life, pain, and key cytokine level in SSc compared with placebo in SScpatientst and the adverse events associated with cannabinoids in those patients.

Interventions

Type	Name	Description
DRUG	CBD oil	The subjects will receive cannabis 2.7 mg THC 2.5 mg CBD twice daily (1 droplet twice daily; 0.73 mg THC and 0.81 mg CBD/drop, 1.46 mg THC and 1.62 CBD/day) for 1 week then titrate up to 2 droplets twice daily if tolerated (2.92 mg THC and 3.24 CBD per day) and continue the treatment until the end of the study.
DRUG	Placebo	The subjects will receive 1 droplet of placebo twice daily then titrate up to 2 droplets twice daily if tolerated and continue the treatment until the end of the study.
