Comparative analysis of addiction severity and renal functions in patients with synthetic cannabinoid use disorder versus cannabis use disorder

Abstract

Abstract Background The use of synthetic cannabinoids (SC) has become a concerning public health issue due to their potential adverse effects on both physical and mental health. Understanding the effect of cannabis and synthetic cannabinoids use on kidney functions and creatinine phosphokinase-total (CPK) levels is essential for targeted intervention and patient care. Methods This cross-sectional study aimed to assess addiction severity using the Addiction Severity Index (ASI) and kidney functions in 45 patients with SC use disorder and compare them to 45 patients with cannabis use disorder (CUD). Participants were recruited from the addiction outpatient clinics and inpatient ward of the addiction psychiatry unit at “Kasr Al Aini Hospital,” Cairo University. Results There was a statistically significant difference between the 2 groups regarding the Addiction Severity Index domains, where patients with SC use disorder had higher scores in all domains of the ASI. Regarding kidney functions and CPK-total levels, there was a significant difference in the serum CPK-total level (p < 0.05) between the 2 groups; however, there was no significant difference regarding the other kidney function tests (serum creatinine, urea, blood urea nitrogen, and estimated glomerular filtration rate). As for the correlative analysis, there was a significant correlation between some domains of the ASI and the kidney function tests in both patient groups. Conclusion Our results strongly suggest that SC may have a more hazardous and detrimental impact on individuals, encompassing various aspects of addiction severity such as physical health, psychological well-being, social functioning, and overall quality of life. Our findings also highlight the potential risk of elevated CPK-total levels in patients with SC use disorder; therefore, regular monitoring of kidney function in patients with synthetic cannabinoid use disorder is crucial for guiding appropriate treatment interventions and mitigating adverse health outcomes.
