People with HIV had altered endocannabinoid levels, but cannabis use frequency did not change immune markers

People living with HIV had higher inflammatory markers and lower endocannabinoid levels than HIV-negative peers, but cannabis use frequency did not affect these immune measures.

What This Study Found

PLWH had higher TNFR2 (p=0.013) and CD27 (p=0.004) and lower anandamide (p=0.027) and OEA (p=0.007) versus HIV-negative men. Cannabis use frequency did not impact any serum analyte.

Key Numbers

36 men (19 PLWH). TNFR2 and CD27 higher in PLWH. Anandamide and OEA lower. Cannabis frequency: no effect on any analyte.

How They Did This

Longitudinal study of 36 MSM in LA (19 PLWH). Each contributed visits during daily and infrequent cannabis use. Serum analyzed for immune biomarkers and endocannabinoids.

Why This Research Matters

Lower endocannabinoid levels in PLWH suggest HIV affects the body's cannabinoid system. The null finding on cannabis frequency is reassuring for PLWH who use cannabis.

The Bigger Picture

HIV alters endocannabinoid levels, pointing to FAAH enzyme activity as potentially important in HIV-related immune dysfunction.

What This Study Doesn't Tell Us

Very small sample (n=36). PLWH had higher methamphetamine and cigarette use. MSM population.

Questions This Raises

  • ?Would FAAH inhibitors normalize endocannabinoid levels in PLWH?
  • ?Do findings generalize beyond MSM?

Frequently Asked Questions

Does cannabis affect the immune system in HIV?

Cannabis use frequency did not change immune markers here. However, HIV itself lowered endocannabinoid levels, suggesting the virus affects the body's cannabinoid system.

What are endocannabinoids?

Molecules your body naturally produces that work through the same receptors as cannabis. Anandamide and OEA were both lower in PLWH.
