Effectiveness of 5-aminolevulinic acid photodynamic therapy in treating dissecting cellulitis of the scalp and pathological changes in skin lesions: A retrospective study. Photodiagnosis Photodyn Ther 2024; 48:104227. [PMID: 38821237 DOI: 10.1016/j.pdpdt.2024.104227] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Revised: 05/11/2024] [Accepted: 05/28/2024] [Indexed: 06/02/2024]
Abstract
BACKGROUND Dissecting cellulitis of the scalp (DCS) has a significant impact on the physical well-being and body image of the patient. Since DCS often responds poorly to conventional treatments, there is a need to identify alternative treatment strategies. This study aimed to explore the effectiveness of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) in treating DCS. METHODS Twelve male patients with DCS treated solely with ALA-PDT between June 2022 and June 2023 at our institution were enrolled in this study. Two patients underwent a biopsy before and after treatment for comparison. The efficacy of the treatments was assessed 10 days after treatment by evaluating the symptom scores recorded on medical records and by assessing the photographs acquired before and after treatment. In addition, the impact of the treatment on pain relief and median recurrence rate were also extracted. RESULTS Out of the 12 enrolled patients, the majority of the patients (75%) had a significant reduction in the nodules or abscesses. The pain relief was significant in 3 patients (25%), and moderate in 7 patients (58.3%). For the subcutaneous sinus tract symptoms, 3 patients (27.3%) showed moderate improvement, and 7 (63.6%) had a mild improvement. Six patients (75%) had mild improvement in their alopecia. The pathology results showed a decrease in the number of lymphocytes, macrophages, and neutrophils within the skin lesions following the administration of ALA-PDT. CONCLUSION ALA-PDT can effectively reduce the DCS symptoms and the number of lymphocytes, macrophages, and neutrophils within the skin lesions.

Abstract
BACKGROUND Dissecting cellulitis of the scalp (DCS) is a chronic inflammatory skin condition characterized by abscesses, nodules, fistulas, and scarring alopecia. Management of this oftentimes debilitating dermatosis can be challenging due to its recalcitrant nature. There is limited data regarding the efficacy of treatment options for DCS. OBJECTIVE The aim of this study was to conduct a systematic review of the literature to explore the efficacy and safety of reported DCS treatments. METHODS In October 2022, MEDLINE and EMBASE databases were searched for articles on treatments for DCS. Studies that contained outcome efficacy data for DCS treatments were included. Reviews, conference abstracts, meta-analyses, commentaries, non-relevant articles, and articles with no full-text available were excluded. Data extraction was performed by two independent reviewers. RESULTS A total of 110 relevant articles with 417 patients were identified. A majority of studies (86.4%) were case reports or series. Treatment options included systemic antibiotics, oral retinoids, biologics, procedural treatments, combination agents, and topical treatments. Oral retinoids and photodynamic therapy were the most extensively studied medical and procedural interventions, respectively. CONCLUSION Overall, randomized controlled trials are needed to evaluate various treatment regimens for DCS and provide patients with a robust, evidence-based approach to therapy.

Abstract
Rosacea is difficult to treat. Therefore, new alternative modalities are necessary to demonstrate. The present study was conducted to assess the efficacy and safety of the combined therapy of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) and intense pulsed light (IPL) for rosacea to provide a new treatment option for rosacea. The study was conducted from November 2017 to April 2019 at the Department of Dermatology, The First Hospital of China Medical University. Patients aged 18-65 years and diagnosed clinically as erythematotelangiectatic (ET) or papulopustular (PP) rosacea were enrolled. Three times of ALA-PDT at 10 days interval followed by 3 times of IPL at 3-4 weeks interval were defined as 1 session and applied to the whole face of each patient. ALA-PDT: 5% ALA, red light (fluency dose 60-100 mW/cm2, 20 min); IPL: 560/590/640 nm, double/triple-pulse mode, pulse width 3.0 to 4.5 ms, delay time 30-40 ms, energy fluency 14-17 J/cm2. Ten patients were enrolled in the study. Among them, 4 patients received only 1 session, while 6 patients received 2 sessions. After all treatments, 50% of patients achieved 75-100% improvement, and 30% achieved 50-75% improvement. Forty percent of patients were graded very satisfaction and 30% graded moderate satisfaction. All noninvasive measurements showed no significant differences among all time points (p > 0.05). The side effects were pain, burning sensation, itching, erythema, desquamation, slight edema, slight exudation, and hyperpigmentation. All of which were tolerable and recovered in a few days. The combined therapy of ALA-PDT and IPL showed an effective option for rosacea with a safety profile.

[PMID: 34551324 DOI: 10.1016/j.pdpdt.2021.102544] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2021] [Revised: 09/14/2021] [Accepted: 09/17/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND Dissecting cellulitis of the scalp (DCS) is a rare but distinctive, chronic suppurative condition, and the treatment is a therapeutic challenge. Recently, treatment of DCS with 5-aminolaevulinic acid photodynamic therapy (ALA-PDT) has been considered as a potential option. OBJECTIVE To evaluate the efficacy and safety of 20% ALA-PDT pretreated by fire needle in the treatment of DCS. MATERIALS AND METHODS Topical 20% ALA-PDT with fire needle intervention as a pretreatment, was applied to six patients with DCS. All patients completed three sessions treatment at an interval of ten days. They were assessed for the efficacy at the baseline and on ten days after each treatment. According to the reduction of lesions and the improvements of patients' symptoms after each session, the objective assessment of therapeutic effect was divided into four grades. The adverse effects were recorded. RESULTS A total of six male patients were enrolled in our study. After three sessions of ALA-PDT, among them, three patients recovered, two patients achieved significant improvement and one patient achieved partial response.Patient 4 (Pt.4) relapsed at 6-month follow-up. Pt.1 and Pt.6. maintained complete response after one year follow-up. We also found that the clearance rate of the popular/nodular and cyst/abscess was much higher than sinus. CONCLUSION 20% ALA-PDT pretreated by fire needle could be an effective, minimally-invasive, safe method for DCS patients. Lesion in the early stages have a better response than sinus.
