Photobiomodulation and antimicrobial photodynamic therapy for oral cytomegalovirus reactivation following acute graft-versus-host disease.

Abstract:

:The relationship between cytomegalovirus (CMV), a severe complication in immunocompromised patients, and graft-versus-host disease (GVHD) has already been reported but remains without complete elucidation, especially concerning oral lesions. Considering that antimicrobial photodynamic therapy (aPDT) has an antimicrobial effect and photobiomodulation therapy (PBM) provides analgesia and modulation of inflammatory processes, the present study aimed to report a clinical case in which oral CMV reactivation following acute GVHD was treated by a combination of aPDT and PBMT concomitantly with conventional drug treatment. Intense and uninterrupted oral pain and consequent impairment of the patient's oral functions were present due to ulcerated lesions in the tongue, soft palate, and labial mucosa. After 72 hours from the first laser session, a marked decrease in the severity of the lesions and pain relief was observed. All oral lesions were repaired within 30 days. Based on this case report, when used concomitantly with conventional drug treatment, the combination of aPDT and PBMT seems to play a crucial role in treating CMV associated with GVHD.
