Filter by:Introduction This document is a clinical trial protocol. This research will be conducted based on the standards of the Good Clinical Trial Method and regulations from the relevant institutions and ethics committees. Background Acne vulgaris (AV) is a chronic inflammatory disease with multifactorial causes in the skin's pilosebaceous follicular units, with clinical manifestations in the form of comedones, papules, pustules, nodes, and pseudocysts. The following factors are considered important for the etiology of AV: increased rate of sebum excretion, endocrinological factors such as androgens, abnormal keratinization of the follicular infundibulum, the proliferation of Cutibacterium acnes (C. acnes), and inflammation. Recent studies at the molecular and cellular levels have clarified how these factors interact and the role of the innate immune system. Inflammatory processes have been demonstrated in all types of lesions - preclinical microcomedones, comedones, inflammatory lesions, 'post inflammatory' erythema or hyperpigmentation, and scarring. Inflammation localized to the pilosebaceous can be considered a hallmark of acne and should be managed through several therapeutic routes. Clinicians tend to think that oral antibiotics should be used to treat inflammation in acne. However, this treatment are associated with resistance and low outcome due to its adverse events such as erythema, desquamation, and dry skin. There is evidence of the use and opportunity of vitamin D as a novelty treatment influencing the immune system. 25OHD and 1,25(OH)2D are both catabolized by CYP24A1. 1,25(OH)2D is a ligand for the vitamin D receptor (VDR), a transcription factor that binds to sites in DNA called vitamin D response elements (VDRE). Thousands of these binding sites regulate hundreds of genes through several signaling pathways in different cell types, including their regulation in immune cells by toll-like receptors (TLRs), the primary signaling nucleus of C. acnes that interacts with the innate immune system, causing acute and chronic inflammation. Study Objectives Primary Objective The primary objective of this study is to evaluate the efficacy and safety of combination topical vitamin D and supplementation as adjuvant therapy in acne vulgaris compared to placebo and topical vitamin D monotherapy. Secondary Objective(s) To assess Vitamin D Receptor (VDR) expression on acne lesion and blood sample To assess the effect of combination topical vitamin D and supplementation on IL-1β expression on acne lesion To assess the effect of combination topical vitamin D and supplementation on IL-6 expression on acne lesion To assess the effect of combination topical vitamin D and supplementation on IL-10 expression on acne lesion To assess the effect of combination topical vitamin D and supplementation on IL-17 expression on acne lesion
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.
1. Acne is a chronic inflammatory disease involving the hair follicles and sebaceous glands, characterized by acne, papules, pustules, nodules, and cysts. Acne often occurs in sebum overflow areas such as the face, chest, back and so on. It is a common skin lesion, which not only affects physical health, but also brings psychological disorders and psychosocial problems to patients. At present, the common treatment methods of acne include health education, topical drugs, oral drugs and medical cosmetic treatment. 2. Intense pulsed light has been widely accepted as a non-invasive and non-serious treatment for acne. The M22 strong light and laser system Acne filter has a wavelength of 400-600/800-1200nm. 3. Although there are many treatments for acne, the slow response and easy recurrence of acne are still common problems that trouble doctors and patients. We clinically use drugs combined with intense pulsed light treatment, and the efficacy of the patients is fair, but currently lack of clinical research data support. This study intends to evaluate the effectiveness of different methods in the treatment of moderate and severe acne by evaluating different bands of intense pulsed light combined with drugs, and to observe whether the treatment with oral tetracycline antibiotics combined with intense pulsed light is safe.
