This systematic review evaluated the efficacy and safety of photodynamic therapy (PDT) in the management of cutaneous leishmaniasis (CL). The electronic search for identification of relevant studies, adhered to the PICOS (Population, Intervention, Comparator, Outcomes and Study type) framework, was conducted through PubMed, Google scholar, Dimensions, X-mol, and Semantic Scholar till December 2023. All types of studies reporting PDT in the management of CL with no language restriction were included. Methodological quality appraised of the selected studies was performed using Jadad index. Of the 317 identified studies, 21 reported PDT for the treatment of CL lesions, consisting of two randomized controlled trials (RCTs), four single-center open study, one case series and 14 case reports. Collectively, these studies presented a total of 304 patients with ages ranging from 1 to 82 years, undergoing varying number of PDT sessions (3-28) and follow-up durations spanning 4 weeks to 24 months. The CL lesions predominantly manifested on the exposed body areas, such as face, limbs, neck, ear and nose, and characterized with the use of clinical variables, such as plaques, papules, erythema and ulceration. PDT protocols differed in the photosensitizer type, incubation time, light source characteristics (e.g., wavelength, output power, and energy density), duration of light illumination, number of PDT sessions and their respective frequencies. Treatment response was assessed through the clinical presentation (i.e., at the baseline and after PDT completion) or by the absence of Leishmania parasites. Adverse effects comprised of pain, burning and tingling sensation experienced during PDT, followed by erythema, pigmentation changes and edema post-treatment. This systematic review revealed that PDT is an efficacious and safe modality for the treatment of CL, with mild and transient side effects.
