Filter by: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
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 a depigmenting skin disorder, characterized by the selective loss of melanocytes, which in turn leads to loss of pigment in the affected areas of the skin It considerd as autoimmune disease, associated with genetic and environmental factors together with metabolic, oxidative stress and cell detachment abnormalities The disease affects both genders equally, it can appear at any age, and the average age of onset is somewhat variable in different geographic . with an estimated prevalence of 0.5-2% of the population in both adults and children worldwide 5-Flourouracil is an antimetabolite analogue of the naturally occurring pyrimidine uracil which is metabolised via the same metabolic pathways as uracil Due to its antimitotic activity, topical 5-Flourouracil is a useful therapy for the treatment of many dermatological disorders characterized by a high mitotic rate Clinically, localized hyperpigmentations have been reported during systemic treatment of various cancers by 5-Flourouracil. Usually, these hyperpigmented lesions are located on the normally pigmented extremities (hands and feet) and tongue. Methotrexate as an antimetabolite and antifolate drug is a time-tested effective treatment extensively used in various autoimmune disorders in low to moderate doses with good efficacy, safety, and tolerability on a long-term basis . Methotrexate treatment resulted in the decrease of the number of TNF-α-producing T cells, whereas the number of T cells producing IL-10 after polyclonal activation increased, in another study .
This work aims to assess sensory symptoms in early active vitiligo patients (segmental, non-segmental, or mixed) and to measure 3 neuropeptides expression in their lesional skin [neuropeptide Y(NPY), calcitonin gene-related peptide (CGRP), and nerve growth factors (NGF)] to correlate neuropeptide levels, sensory symptoms, and functions, with criteria of disease activity and perceived stress scale.
Standard treatment for vitiligo often has unsatisfactory outcomes. With a new understanding of pathogenesis, novel drugs have been introduced which have shown to be effective in small-scale studies. Tofacitinib, a Janus kinase(JAK) inhibitor-2 has shown promising results in the treatment of vitiligo. However, randomized controlled studies are required to confirm these observations and identify the patients most likely to benefit from JAK-2 inhibition. This open-labeled randomized clinical trial will be conducted at the department of dermatology and venereology of US Bangla Medical College & Hospital in Dhaka for 6 months duration from June 2021 to November 2021 to Vitiligo patients attending in the aforementioned department will be approached for inclusion in the study. Finally, 80 patients who will fulfill the inclusion and exclusion criteria will be included. All patients will be informed about the nature of the study and the written consent will be taken in the consent form with the assurance that their information will be made confidential. Baseline information such as gender, age, disease history, and drugs used prior will be collected. All patients will undergo baseline laboratory evaluation which will be repeated at 6weeks and 12weeks. Before the beginning of treatment, digital images of the cutaneous lesions will be taken which will be compared with the ones taken at 6weeks and the end of 12weeks follow up. The participants will undergo randomization into 1:1 ratio into two equal groups. Group A will receive oral Tofacitinib and Group B will receive topical 0.1%Mometasone furoate. All the participants will receive allotted intervention for 12weeks. The patient will be followed up at 6 weeks and end of 12 weeks. The primary outcome of the study will be the improvement of the Vitiligo Area Scoring Index (VASI) score at 6 and12 weeks in all groups. Secondary outcomes will include improvement in Vitiligo European Task Force (VETF) scoring. The data will be systematically described and summarized and presented through descriptive statistics and finally will be analyzed by the statistical program Statistical Package for Social Science (SPSS) version 23.0(Chicago, Illinois, USA). The relevant statistical test will be used during the analysis. In all cases, the significance level will set p <0.05. Ethical clearance of the study will be obtained from the ethical review committee (ERC) of the study place.
