Vitiligo is a chronic auto-immune depigmenting skin disorder that results from a loss of melanocytes. Multiple combinatorial factors have been involved in disease development, with a prominent role of the immune system, in particular T cells. After repigmentation, vitiligo frequently recurs in the same area, suggesting that vitiligo could involve the presence of resident memory T cells (TRM). We sought to perform a thorough characterization of the phenotype and function of skin memory T cells in vitiligo. We show that stable and active vitiligo perilesional skin is enriched with a population of CD8 TRM expressing both CD69 and CD103 compared to psoriasis and control unaffected skin...

Evidence has emerged about the relationship between atopic dermatitis (AD) and autoimmune diseases, but the underlying mechanism of this association is complex and still unclear. Recent epidemiological data from the published work suggest a positive correlation. The aim of this review is to analyze the frequency of co-occurrence of AD and autoimmune diseases. Our systematic review included 22 articles from PubMed describing the reciprocal association between AD and autoimmune diseases. Although not all the studies achieved statistically significant results, patients suffering from autoimmune diseases involving skin and intestinal mucosa, such as vitiligo, alopecia areata, celiac disease and inflammatory bowel diseases, showed a higher risk to have AD as comorbidity...

Vitiligo is a disorder characterized by the development of depigmented macules and patches. Existing treatments include topical and systemic immunosuppressants, topical vitamin D analogues in monotherapy or in association with phototherapy, phototherapy and surgical techniques, which together may serve to halt disease progression, stabilize depigmented lesions, and encourage repigmentation. Narrow-band UVB (NB-UVB 310-315 nm) radiation is now considered as the "gold standard" for the treatment of diffuse vitiligo...

The promising results derived from the use of adipose-derived stem cells (ADSCs) in many diseases are a subject of observation in preclinical studies. ADSCs seem to be the ideal cell population for the use in regenerative medicine due to their easy isolation, nonimmunogenic properties, multipotential nature, possibilities for differentiation into various cell lines, and potential for angiogenesis. This article reviews the current data on the use of ADSCs in the treatment of vitiligo, various types of hair loss, and the healing of chronic wounds...

Polyglandular autoimmune syndrome (PAS) type 3 consists of autoimmune thyroid disease (AITD) coexisting with ≥1 non-thyroidal autoimmune disease (NTAID) other than Addison's disease and hypoparathyroidism. We evaluated the prevalence and repertoire of thyroid hormones antibodies (THAb) in PAS-3 patients. Using a radioimmunoprecipation technique, we measured THAb (T3IgM, T3IgG, T4IgM, and T4IgG) in 107 PAS-3 patients and 88 controls (patients with AITD without any NTAID). Based on the selective coexistence of AITD with one NTAID (chronic autoimmune gastritis, non-segmental vitiligo or celiac disease), patients were divided into group 1 (chronic autoimmune gastritis positive, n = 64), group 2 (non-segmental vitiligo positive, n = 24), and group 3 (celiac disease positive, n = 15)...

Alopecia areata (AA) is a common autoimmune disease and it is challenging to predict which patients will have severe disease. The purpose of this retrospective study was to identify comorbidities in children enrolled in the National Alopecia Areata Registry. Atopic dermatitis was more common in patients with severe AA than in those with mild disease. The most common autoimmune comorbidities were vitiligo, psoriasis, thyroid disease, and juvenile idiopathic arthritis.

Vitiligo is a disorder of skin pigmentation. It affects approximately 1% of the world's population. Vitiligo occurs equally between the sexes with no racial predilections. The majority of cases are acquired and arise between the second and third decades of life. Acquired vitiligo has an unpredictable clinical course. Congenital vitiligo is rare with few reported cases. Due to the rarity of congenital vitiligo, little is known about the clinical course. For patients with acquired or congenital vitiligo, the psychosocial burden can have a profound impact on quality of life...

BACKGROUND: Centella asiatica (L.) Urb. is a traditional Chinese medicine that has many medical applications, including wound healing and anti-oxidation. Some traditional Chinese Medicine doctors have found that it has therapeutic effects for external use in the repigmentation of vitiligo and post-inflammatory hypopigmentation. This study was designed to evaluate the effects of madecassoside, a major bioactive component of C. asiatica, on oxidative stress in human melanocytes and its possible mechanism of action...

BACKGROUND: Oxidative stress is known to be involved in the pathogenesis of autoimmune diseases such as vitiligo. Evidence suggests that the human mitochondrial DNA copy number (mtDNAcn) is vulnerable to damage mediated by oxidative stress. The purpose of this study was to examine and compare peripheral blood mtDNAcn and oxidative DNA damage byproducts (8-hydroxy-2-deoxyguanosine; 8-OHdG) in patients with vitiligo and healthy controls (HCs). METHODS: The relative mtDNAcn and the oxidative damage (formation of 8-OHdG in mtDNA) of each sample were determined by real-time quantitative PCR...

In the past decade, adipose tissue has become a highly interesting source of adult stem cells for plastic surgery and regenerative medicine. The adipose source offers two options for the isolation of regenerative cells: the enzymatic digestion an expensive time-consuming procedure lacking a common standard operating protocol, or the non-enzymatic dissociation methods based on mechanical forces to break the processed adipose tissue. Here, we propose innovative inexpensive non-enzymatic protocols to collect and concentrate clinically useful regenerative cells from adipose tissue by centrifugation of the infranatant fraction of lipoaspirate as first step, usually discarded as a byproduct of the surgical procedure, and by fat shaking and wash as second enrichment step...

BACKGROUND AND AIMS: Stable vitiligo can be treated by various surgical procedures. Non-cultured melanocyte grafting techniques were developed to overcome the time-consuming process of culture while at the same time providing acceptable results. All the techniques using non-cultured melanocyte transfer involve trypsinisation as an integral step. Jodhpur technique used by the author is autologous, non-cultured, non-trypsinised, epidermal cell grafting. SETTINGS AND DESIGN: The study was conducted on patients visiting the dermatology outpatient department of a tertiary health centre in Western Rajasthan...

In vitiligo, chronic loss of melanocytes and consequent absence of melanin from the epidermis presents a challenge for long-term tissue maintenance. The stable vitiligo patches are known to attain an irreversible depigmented state. However, the molecular and cellular processes resulting in this remodeled tissue homeostasis is unclear. To investigate the complex interplay of inductive signals and cell intrinsic factors that support the new acquired state, we compared the matched lesional and non-lesional epidermis obtained from stable non-segmental vitiligo subjects...
