Filter by:This study is to evaluate the effectiveness and tolerability of autologous punch minigraft, transverse needling technique or combination of both followed by narrow band ultraviolet B phototherapy (311 nm) in the treatment of patients with stable non-segmental vitiligo lesions.
In this study, the investigators demonstrated that in vivo THG microscopy can differentiate vitiligo lesions and normal skin based the optical nature of melanin. This THG-based procedure provides a valuable tool for noninvasive determination of third-order nonlinear susceptibility of melanin within the skin. It can also provide real-time histopathology information for treatment follow-up, without performing invasive skin biopsy.
The cohort included only major patients with non-segmental vitiligo and no other autoimmune or inflammatory associated diseases (except thyroiditis). Control subjects should have no autoimmune or inflammatory diseases. Patients and controls should not take treatment with corticosteroids or other potentially immunomodulatory therapies. Patients and controls are recruited in the Dermatology Department of the University Hospital of Nice and the Hospital of Fréjus. The investigators have already initiated the collection of tissues and blood from patients and control subjects and we have succeeded in isolating ILCs and NKs from a blood volume of 50ml. We were able to sort the ILC subpopulations. Early data suggest an increase in Natural Killer (NK) and Innate Lymphoïdes Cells 1 (ILC1) in the blood of vitiligo patients compared to control subjects. The investigators also managed to extract the melanocytes from the skin biopsies of the first patients and control subjects.
There is a need to know the role of human beta defensin-1 in vitiligo pathogenesis and the probability of finding newer and effective therapy for vitiligo in the future.
Vitiligo is a chronic depigmenting autoimmune-associated skin disease and a growing psychological health concern because of its low quality of life. Genetics, immunology and environment triggers contribute to the pathophysiology of vitiligo. Identify and decrease the risk factors of vitiligo is very crucial for vitiligo treatment and prevention. Emerging evidence has linked gut microbiome to human autoimmune diseases. Here the investigators will analyze 10,913 metagenomes in stool samples from 100 adult vitiligo patients and gut microbiome associated metabolites in patients serum.
Assessment of the level of JAK1 in both vitiligo and psoriasis patients before and after treatment with NB-UVB which is considered a gold standard therapy for both diseases.
study the cutaneous expression of PGF2α in vitiligo patients and compare it with normal control subjects.
Vitiligo is an acquired depigmented disorder that causes white spots on the skin due to the loss of melanocytes. It is a common disease which accounts for 0.5-1% of the whole population. It is a refractory skin disease with 25-50 thousand patients in Korea. And it is often caused in the exposed areas of the patient, causing a great deal of mental and social dysfunction in the patient's life, and may lead to suicide attempts.
Vitiligo is a relatively common acquired disorder of pigmentation characterized by the development of well-defined white macules on the skin. Biopsies of lesional skin reveal a loss of epidermal melanocytes. Lesions may occur in a localized or generalized distribution and may coalesce into large, depigmented areas. Given the contrast between the white areas and normal skin, the disease is most disfiguring in darker skin types and has a profound impact on the quality of life of both children and adults . Patients with vitiligo often experience stigmatization, social isolation, and low self-esteem. The therapys include topical steroids, topical immunosuppresant, systemic steroids, phototherapy, and surgery. The aim of this study is to investigate the effect of phototherpy and accupuncture combined therapy for vitiligo patients.
