Use of different anticholinergic scales and their correlation with anticholinergic symptom burden in a cohort of people living with HIV.

Up to one-fourth of participants in our cohort were exposed to at least one AC drug, and among them AC signs/symptoms affected more than one-fourth. Both polypharmacy (as number of antiretrovirals and of co-medications with AC properties) and to a lesser extent specific comorbidities shaped the risk of developing AC signs/symptoms. Sensitive screenings for AC risk in PWH should prefer ABS or ADS based on lower cut-offs than those suggested for the general population.
