Cannabinoids may not effectively treat HIV wasting syndrome. Evidence is very low certainty, and frequent adverse effects are probable, questioning their safety and efficacy for weight gain.
Area of Science:
- Medical research
- Clinical nutrition
- Pharmacology
Background:
- HIV-associated wasting syndrome is a significant clinical issue.
- Cannabinoids are proposed for managing weight loss in HIV patients.
- Evidence regarding cannabinoid safety and efficacy for HIV wasting is limited.
Purpose of the Study:
- To evaluate the effectiveness of cannabinoids for HIV wasting syndrome.
- To assess the safety profile of cannabinoids in this patient population.
Main Methods:
- Systematic review of evidence using the Epistemonikos database.
- Inclusion of multiple databases (MEDLINE, EMBASE, Cochrane).
- Data extraction from systematic reviews and reanalysis of primary studies using GRADE methodology.
Main Results:
- Eight systematic reviews comprising ten studies were identified.
- Six of these studies were randomized controlled trials.
- The certainty of evidence for cannabinoid efficacy was very low.
Conclusions:
- It remains unclear if cannabinoids improve appetite or weight in HIV wasting syndrome.
- Cannabinoids are associated with frequent adverse effects.
- Further high-quality research is needed to clarify the role of cannabinoids.
