Inflammation Markers Among Schizophrenia Patients Who Use Cannabis

Area of Science:

• Neuroscience
• Immunology
• Psychiatry

Background:

• Inflammatory markers like neutrophil-to-lymphocyte ratio (NLR) and mean platelet volume (MPV) are linked to schizophrenia.
• Cannabidiol, a component of cannabis, may reduce acquired immune system activation.

Purpose of the Study:

• To investigate differences in NLR and MPV levels in schizophrenia patients with versus without cannabis use.
• To explore the potential impact of cannabis use on specific immune system inflammatory markers in schizophrenia.

Main Methods:

• A retrospective cross-sectional study using digital medical records from 2019-2020.
• Collected demographic, clinical, and complete blood cell count data from schizophrenia inpatients.
• Compared NLR and MPV values between groups based on cannabis use prevalence.

Main Results:

• No statistically significant differences were observed in NLR or MPV values between schizophrenia patients with and without cannabis use.
• Cannabis use did not appear to alter these specific inflammatory markers in the studied population.

Conclusions:

• The study's findings were unexpected and contrary to the hypothesis that cannabis use would alter NLR and MPV in schizophrenia.
• The "pseudo-balanced" picture of inflammatory indices may result from multiple interacting processes, masking the effect of cannabis use.
