Currently accepted that oxidative stress is a triggering event in the melanocytic destruction and is probably involved in the etiopathogenesis of vitiligo disease. Despite numerous investigations, contradictory results were reported about the levels of oxidative stress biomarkers measured in the skin and blood of vitiligo patients. By Electron Paramagnetic Resonance spectroscopy (EPR) and spectrophotometry, we have investigated and compared some oxidative stress biomarkers in the blood of vitiligo patients' before and after UVB Narrow Band 311 nm phototherapy combined with the antioxidant nutritional supplement containing - Vitamin C, Vitamin B1, L -Cysteine, Lipoic Acid, and polyunsaturated fatty acids...

This retrospective study aimed to identify factors that predict treatment response in a cohort of Asian children with vitiligo. Shorter duration of vitiligo was associated with better repigmentation. Patients with focal vitiligo of short duration have a good chance of achieving repigmentation with topical agents alone.

Aim: The aim of the present study is to compare the gingival melanin repigmentation after diode laser application and surgical removal done by scraping with Kirkland knife. Materials and Methods: This study was a randomized split-mouth study where 10 patients presenting with unattractive, diffuse, dark brown to black gingival discoloration on the facial aspect of the maxillary gingiva were treated by diode laser application and surgical removal and followed up for 3-, 6-, and 9-month intervals...

Importance: Epidermal cell suspension (ECS) and follicular cell suspension (FCS) are successful surgical modalities for the treatment of stable vitiligo. However, repigmentation in generalized and acrofacial vitiligo and over acral or bony sites (eg, elbows, knees, iliac crests, and malleoli), which are difficult to treat, is challenging. Objective: To study the efficacy of transplanting a combination of autologous, noncultured ECS and FCS (ECS + FCS) compared with ECS alone in stable vitiligo...

Surgical management of vitiligo is considered an excellent terapeutic option for recalcitrant cases, provided the disease is stable and there is absence of Koebner phenomenom. Among surgical modalities, Suction Blister Epidermal Graft is a low cost and effective option (65 to 100% repigmentation can be achieved in up to 80% of patients). We describe how it can be optimized by using an alternative suction equipment, by customization of graft format and by application of an anesthetic technique that substantially reduces procedure time...

Vitiligo is an acquired depigmenting disorder. To date, there is no predictive model for its response rate to narrowband ultraviolet B (NBUVB) phototherapy. The aim of this study was to investigate the different types of response of patients with non-segmental vitiligo undergoing NBUVB 3 times a week. Many patients who were previously considered non-responders were given the opportunity to continue the treatment. Long-term maintenance of treatment and follow-up of a cohort of 579 patients enabled different subtypes of response (very rapid, rapid, average, slow and "non-responders") to be described for the first time, and a predictive model of response to be constructed based on repigmentation rate in the first 48 sessions of NBUVB...

Vitiligo is an acquired pigmentary skin of depigmentation occurring secondary to melanocyte destruction. Vitiligo and other leukodermas have a profound impact on quality of life. Current therapies include medical options, such as phototherapy, topical and systemic corticosteroids, topical calcineurin inhibitors, immunomodulators, and antioxidiants, and surgical options. Surgical options provide melanocytic cells to previously depigmented areas and use either tissue grafting or cellular grafting methods. Topical treatments are often insufficient, and many of the current surgical procedures have shown variable response rates...

BACKGROUND: Patients with vitiligo present with different repigmentation patterns in the early recovery stage. OBJECTIVES: To analyze the relationships between early repigmentation patterns in vitiliginous patches, their clinical characteristics, and therapeutic choices. METHODS: Patients with vitiligo seen in the Department of Dermatology, The First Affiliated Hospital of Nanjing Medical University from 2010 to 2015, were included, and their clinical records, especially photographs and medical treatments, were reviewed...

INTRODUCTION: Phototherapy is the cornerstone of treatment of vitiligo. The 308-nm excimer lamp (EL) induces T cell apoptosis and the stimulation of melanocyte proliferation. Khellin is a furanochromone with a chemical structure close to psoralens. The objective of the study was to evaluate the safety and efficacy of 1-year treatment of recalcitrant vitiligo with a combination of 308-nm EL and khellin. METHODS: Twenty patients with resistant vitiligo were included...

Vitiligo is a common pigment disorder characterized by acquired loss of function or absence of melanocytes, leading to distinct areas of depigmentation. Physical exam reveals sharply demarcated, depigmented macules or patches on otherwise normal skin. Vitiligo can present at any age, in any skin color. There is no specific serologic marker for diagnosis, but patients often have other autoimmune problems. Treatment options are limited and are difficult given the fact that the pathogenesis of the disease is not well elucidated...

BACKGROUND: Vitiligo is a chronic disease characterized by the appearance of achromic macules caused by melanocyte destruction. Surgical treatments with melanocyte transplantation can be used for stable vitiligo cases. OBJECTIVES: To evaluate treatment response to the autologous transplantation of noncultured epidermal cell suspension in patients with stable vitiligo. METHODS: Case series study in patients with stable vitiligo submitted to noncultured epidermal cell suspension transplantation and evaluated at least once, between 3 and 6 months after the procedure, to observe repigmentation and possible adverse effects...

Introduction: Recently, the monochromatic excimer light (MEL) of 308 nm wavelength has shown some advantages in comparison to narrow band ultraviolet B (NB-UVB) for the treatment of vitiligo. To histopathologically compare the early effects of NB-UVB and 308-nm MEL phototherapy on vitiliginous patches using H&E and HMB-45. Methods: Thirty subjects with non-segmental vitiligo lesions were treated twice a week for 6 weeks with 308-nm MEL, while NB-UVB was used to treat lesions contra laterally. Skin biopsies were taken from lesional areas before and after 6 weeks of treatment by either modality...

In recent years, laser toning or laser facial to treat melasma has become increasingly popular in Asia. It is common to see patients undergoing lasers three times a week, or even daily. This is part of a growing trend and is sometimes recommended in the user manuals from laser manufacturers. In our study, we report on 23 Chinese patients who had lasers performed three times a week for two consecutive months, followed by rest. All 23 of them developed bilateral confetti-like hypopigmentation at the end of two months...

BACKGROUND: Recently, we introduced intralesional injection of autologous epidermal cells as a safe and feasible approach for transplantation in patients with stable vitiligo. This approach resulted in less pain during and after the procedure, no scarring or cobblestone formation at the recipient site, and was more feasible to perform on curved surfaces such as joints, lips, eyelids, ears, and face. OBJECTIVE: In this study, we aimed to investigate the long-term efficacy and safety of this transplantation technique...

BACKGROUND/PURPOSE: Vitamin D has a role in variety of autoimmune diseases including vitiligo. Narrow-band UVB (NB-UVB) treatment of vitiligo might act through its effects on vitamin D and its receptor.This study is the first to elucidate NB-UVB effects on immunohistochemical vitamin D receptor (VDR) expression in generalized vitiligo and correlate it with serum vitamin D and repigmentation response. METHODS: Using immunohistochemistry, VDR expression was estimated in skin biopsies of 30 controls and 30 vitiligo patients; from vitiligo lesion, perilesional skin at baseline and from repigmented and nonresponding skin after 24 NB-UVB sessions...
