Treatment of Herpes Labialis by Photodynamic Therapy

Herpes
Start date: January 1, 2020
Phase: N/A
Study type: Interventional

Lesions of herpes labialis are caused by the herpes simplex virus type 1 (HSV-1) and cause pain and aesthetic compromise. It is characterized by the formation of small vesicles that coalesce and rupture forming extremely painful ulcers, that evolve to crusts, dry desquamations until their complete remission. Currently, the treatment of these lesions is done with acyclovir. Although it diminishes the symptomatology, it causes viral resistance and does not prevent the recurrence of the lesions. It is known that photodynamic therapy (PDT) has numerous advantages, among them: the reduction of the time of remission, and does not cause resistance. A total of 30 patients with herpes labialis in the prodromal stage of vesicles, ulcers, and crusts will be selected to participate in the study and randomized into two groups: G1 control and G2 experimental. After signing informed consent, patients in group G1 will undergo the standard gold treatment for cold sores with acyclovir and simulated PDT treatment. Patients in the experimental G2 group will be treated simulating the gold standard treatment of herpes labialis (placebo) and PDT.
