ABSTRACT
Synthetic Cannabinoid Receptor Agonists (SCRAs) are a group of New Psychoactive Substances. They are used recreationally to mimic the effects of THC in cannabis. However, THC is a partial agonist of the CB1-receptor and SCRAs are full agonists. Because of this specificity and potency serious adverse events may occur among which psychological, cardiovascular, and gastro-intestinal symptoms. Because of the low incidence in the Netherlands clinical information on SCRA intoxications is limited, making diagnosis and treatment difficult. In this clinical lesson, two cases of SCRA intoxications are described followed by treatment recommendations.

Methotrexate (MTX), an important chemotherapeutic agent, is often accompanied with mucositis. The occurrence and severity are unpredictable and show large interindividual variability. In this study, we review and meta-analyze previously studied genetic variants in relation to MTX-induced mucositis. We conducted a systematic search in Medline and Embase. We included genetic association studies of MTX-induced mucositis in cancer patients. A meta-analysis was conducted for single nucleotide polymorphisms (SNPs) for which at least two studies found a statistically significant association. A total of 34 SNPs were associated with mucositis in at least one study of the 57 included studies. Two of the seven SNPs included in our meta-analysis were statistically significantly associated with mucositis: MTHFR c.677C > T (recessive, grade ≥3 vs grade 0-2, OR 2.53, 95 %CI [1.48-4.32], False Discovery Rate[FDR]-corrected p-value 0.011) and MTRR c.66A > G (overdominant, grade ≥1 vs grade 0, OR 2.08, 95 %CI [1.16-3.73], FDR-corrected p-value 0.042).
