Society for Pediatric Dermatology: Top news from the virtual conference. NEW YORK — Progress in understanding the sequence of events that drives vitiligo is not only behind highly promising new options for treatment, but also might be leading to a strategy that will prevent the inevitable relapse that occurs after treatment is stopped, according to an update at the American Academy of Dermatology summer meeting. Recently, trial results with a Janus kinase JAK pathway inhibitor have shown promise for treatment of vitiligo, but the ultimate fix for this recurring autoimmune disease might be elimination of resident-memory T cells, according to John Harris, MD, PhD , of the department of dermatology at the University of Massachusetts, Worcester. In a murine vitiligo model, targeting interleukin, a cytokine thought to be essential for maintaining memory T cells, produced rapid and durable repigmentation without apparent adverse effects in a series of studies sufficiently promising that clinical trials are now being actively planned, Dr. Harris said. The ongoing work to eliminate resident-memory T cells to prevent relapse of vitiligo comes at the end of other recent advances that have provided major insights into the pathophysiology of vitiligo.

DOI: Introduction: Vitiligo is an acquired skin disease characterized by loss of functional melanocytes from the epidermis. Despite the several factors studied the pathogenesis of vitiligo remains unclear. Vitiligo could be associated with low vitamin D levels and high level of interleukin Objective: The aim of this study was to evaluate serum 25 OH D levels, interleukinserumlevels and correlation between them in vitiligo patients in comparison of normal controls.
Patients and Methods: After meeting inclusion and exclusion criteria, serum 25 hydroxy vitamin D and interlukin levels were assayed, in all subjects included in this case control study 21 patients and 21 age and sex matched healthy individuals. Vitiligo disease activity index VIDA , affected body surface area BSA , site of lesion, age of patients and duration of vitiligo were evaluated in relation to vitamin Dand interleukin level. Results: A total of 42 participants were enrolled in our study, 21 patients with vitiligo and 21 who served as controls.
The mean serum level of vitamin D were significantly decreased in the patients group as compared with the control group The mean serum level of interleukin were significantly increased in the patients group as compared with the control group Conclusion: In this study, we found a significant 25 OH D deficiency and significant high level of interleukin in patients with vitiligo, suggesting that vitamin D deficiency and high-level interleukin may play a role in the pathogenesis of vitiligo.
This disfiguring condition frequently affects the face and other visible areas of the body, which can be psychologically devastating . The average age at onset lies around the second to the third decade of life . In recent years, vitamin D deficiency as a result of lifestyles with inadequate sun exposure, has received increased attention due to its association with the risk of serious chronic diseases.

Vitiligo is a disorder in which areas of skin lose color and become white depigmented. Depigmented areas may also appear at sites of injury or sunburn. Although vitiligo may begin rapidly, the disease usually slows or stops over time. Some patients have noted worsening of vitiligo with illness or emotional stress. Whom does vitiligo affect? Vitiligo affects 0. Men and women of all races are equally affected. However, depigmentation is more prominent in people with darker skin.
What causes vitiligo? Vitiligo is caused by the destruction of melanocytes, which are cells in the skin that produce pigment. Patients with vitiligo often have a personal or family history of autoimmune diseases, such as thyroid disease, alopecia areata, juvenile diabetes, or vitiligo itself. How do I know if I have vitiligo? Other conditions may cause the skin to appear light, but vitiligo is one of the only conditions that will cause a total loss of pigment.

Radiation-induced hypopigmentation consistent vitiligo has been reported in a few case reports. We report herewith a case of vitiligo at the site of radiation delivery after a lag of several months in a patient with preexisting hypothyroidism without a previous or family history of vitiligo, and review the cases reported in the literature collectively. Vitiligo is a disease characterized by depigmented macules in the skin that result from a melanocyte loss. Radiation-related melanocyte loss has been described in the literature and has been incriminated for the patches of vitiligo in the radiation port.
After a discussion, patient was operated on with left modified radical mastectomy. Histopathologic examination of the tumor revealed a disease consistent with T2 and N2.
MyVitiligoTeam is a social network and online support group for those living with vitiligo. The goal of MyVitiligoTeam is to offer perspective and validation of others by sharing one’s own personal story. MyVitiligoTeam aims to create a safe place where members feel comfortable discussing their experiences. To protect the overall community and intention of MyVitiligoTeam, we’ve created features that enable all members to report content when guidelines are broken.
While our process is not perfect in addressing all violations, we always strive to put the well-being of the entire community above all else. In reviewing actions of members that may violate our guidelines, we always err on the side of removing content of members who may jeopardize the environment of the site as a safe place for people to connect and share their daily experiences.
Anytime a member’s action is reported for violating community guidelines or terms of service, MyVitiligoTeam will send an email warning to that member, indicating which guideline has been broken. If the warned member continues to break the same guideline or any additional guideline, MyVitiligoTeam will immediately deactivate that person’s account. An email will be sent indicating the nature of the second violation, and the fact that the person’s account was terminated. We aim to swiftly respond to violations of community guidelines to ensure that the site fosters a welcoming and supportive environment.
Study record managers: refer to the Data Element Definitions if submitting registration or results information. The treatment of vitiligo includes both medical and surgical modalities, whose goal is to restore melanocytes to the depigmented skin so that the epidermis restores back to normal morphology and functions. Although medical treatment is the main stay of treatment, it is not effective in all and residual lesions need augmented surgical treatment later for further completion of repigmentation.
Now a day surgical modalities have become treatment of choice for stable vitiligo not responding to medical treatment although there are numerous sites which do not respond that well to surgical procedure as well. The investigators ought to compare the efficacy of 3 well established surgical methods i.
Vitiligo consists of white patches of skin that are caused by the loss of melanin, No content on this site, regardless of date, should ever be used as a substitute.
Vitiligo is a chronic stigmatizing disease, already known for millennia, which mainly affects melanocytes from epidermis basal layer, leading to the development of hypochromic and achromic patches. Its estimated prevalence is 0. The involvement of genetic factors controlling susceptibility to vitiligo has been studied over the last decades, and results of previous studies present vitiligo as a complex, multifactorial and polygenic disease. Notwithstanding, environmental factors that precipitate or maintain the disease are yet to be described.
The pathogenesis of vitiligo has not been totally clarified until now and many theories have been proposed. Of these, the autoimmune hypothesis is now the most cited and studied among experts. Dysfunction in metabolic pathways, which could lead to production of toxic metabolites causing damage to melanocytes, has also been investigated.
