Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a prospective, randomized controlled trial to evaluation the ability of 5-aminolevulinic acid HCL topical solution photodynamic therapy to decrease the colonization of Cutibacterium acnes (C. acnes- a bacteria commonly found in the dermis of the skin surrounding the shoulder) in order to decrease postoperative joint infections. -Aminolevulinic acid (ALA) is a naturally occurring metabolite in the synthesis of pathway of cellular heme production. Adding ALA to bacteria encourages porphyrin production which serve as the immediate precursors to heme production. When these porphyrins are illuminated with blue light at an emission peak of 407-420nm, these metabolites become exothermic and cause internal destruction of the bacterial cells. This therapy does not cause any damage to the mammalian cells, which makes PDT safe for human skin treatment.
