Filter by:Vitiligo is a skin disorder that causes substantial social and psychological distress due to multiple patches of depigmentation.Disease can target at any age, but it appears to affect various parts of body due to loss of melanin. Although the exact cause of the disease is unknown, several theories suggest that genetic predisposition, autoimmunity, and increased vulnerability of melanocytes to the deleterious effects of harmful metabolites all play a role in disease causation. It impacts 0.1%-2% of the general population, with a 30% familial prevalence rate. Vitiligo treatment still presents a therapeutic challenge for dermatologists despite a variety of therapeutic modalities. Topical steroids, ultraviolet B phototherapy (UVB 280nm-320nm), and photochemotherapy (PUVA i.e., psoralen plus UVA 329nm-400nm) are traditional treatment options. Topical calcipotriol and excimer laser are also used. According to research, narrowband UVB (NB-UVB) is effective when used alone. Few studies, however also, have reported more than 75% re-pigmentation in patients treated with NB-UVB in conjunction with other modalities. Topical immunomodulators (tacrolimus, pimecrolimus) are considered safe and effective long-term treatments for vitiligo because they do not cause skin atrophy, which is associated with long-term use of topical corticosteroids. Tacrolimus is an effective treatment for vitiligo when used alone; in one study, 61% of patients showed more than 75% repigmentation when treated with tacrolimus alone. Another study found that when tacrolimus was combined with NB-UVB, 73% of patients experienced more than 50% repigmentation. The objective of this research was to present a comparatively new mode of treatment that may be beneficial to vitiligo patients.
Clinical significance of circulating T regulatory cells , soluble CD25 and CXCL9 to assess disease activity of vitiligo.
Photoacoustic imaging (PAI) is an emerging method which combines light and ultrasound to assess the blood content and oxygenation of the body. Light is absorbed by the blood, leading to the generation of ultrasound, from which the levels of oxygen can be derived. This high sensitivity to blood has seen it applied in multiple clinical trials for the assessment of a number of conditions including breast cancer assessment. However, the accuracy of the measurements and image quality is known to decrease as you look deeper into the body because light intensity decreases. Melanin in the skin is known to absorb light very strongly and so there is considerable concern that this may bias measurements made in people with darker skin tones compared to those with lighter skin tones. In this pilot study, we intend to recruit volunteers with a wide range of skin tones and vitiligo. We will scan a number of blood vessels and muscles using PAI and evaluate the photoacoustic measurements of blood content and oxygenation to identify, and ultimately correct for, biases in advance of further clinical studies.
Evaluation of serum leptin in vitiligo patients and control Assessing its correlation to the body mass index and disease dermographic data .
Interleukin 2 (IL-2) is a critical cytokine for the survival and function of regulatory T cells (LTreg). This cytokine has a dual role in the immune system. IL-2 stimulates immune responses by acting on the intermediate affinity IL-2R receptor, IL-2Rβγ, expressed by conventional T cells (LTconv) during activation, but also contributes to the inhibition of immune responses via LTreg that express the high affinity receptor IL-2Rαβγ. This difference in IL-2 receptor affinity for IL-2 has led to the development of low-dose IL-2 therapy to stimulate LTreg and improve control of excessive inflammation in autoimmune (AID), inflammatory or alloimmune diseases Low-dose IL-2 therapy is being studied in several of these diseases such as systemic lupus erythematosus, type 1 diabetes, alopecia, HCV (hepatitis C virus)-induced vasculitis, atopic dermatitis and chronic allo-transplantation-related graft-versus-host disease (GVHD). Some of these studies have shown an increase in LTreg numbers and an improvement in certain clinical signs. To improve LTreg targeting in autoimmune diseases, inflammatory diseases or GVHD, mutated IL-2s (muteins) have been developed with selective LTreg agonist properties. These IL-2 muteins are linked to an Fc fragment to increase their half-life. Two IL-2 variants (IL-2Vs)-Fc preferentially stimulate STAT5 phosphorylation in LTregs compared to conventional FoxP3- (LTconv) CD4+ or CD8+ T cells
A novel approach for 5-Fluorouracil delivery based on a solid effervescent formulation is proposed . 5-Fluorouracil is water soluble (~50mg/ml) and therefore has been used for the development of novel topical formulations including nano and microparticles intended for skin targeting. After hydration 5-Fluorouracil could form a complex, a suspension or even be formulated to generate effervescence. In effervescent technology, gas bubbles occur from the liquid after chemical reaction between alkali salts and organic acids (mainly citric or tartaric. Due to liberation in CO2 gas, the dissolution of drug in water is enhanced. The aim of this study is the development and clinical evaluation of topical 5-florouracil effervescent powder formulation in the treatment of vitiligo.
To compare the level of circulating functional mitochondria in the serum of vitiligo patients as compared to controls
This study aims to compare the efficacy of topical 5-fluorouracil versus topical latanoprost after skin microneedling in the induction of skin repigmentation in localized stable vitiligo patients.
The aims of this study are to:- Compare the effect of fractional Erbium: YAG laser assisted delivery of platelet- rich plasma versus microneedling with platelet-rich plasma in the induction of skin repigmentation in localized stable vitiligo patients.
Vitiligo is the most commonly acquired depigmentation disorder characterized by selective destruction of melanocytes resulting in well-circumscribed achromic macules. Tissue-resident memory T cells (TRM) are memory T lymphocyte subsets that reside in the skin, lack recirculation, proliferate locally, produce cytokines, and may be implicated in relapses. NB-UVB Phototherapy induces repigmentation in certain patterns. The aim of this study was to determine the levels of TRM cells on vitiligo lesions, and after phototherapy by repigmentation pattern.
