Abstract
Vitiligo is a disease characterized by skin discoloration, and no safe and effective drugs have been developed until now. New drug research and development are imminent. This article reviews the research on small-molecule drugs for vitiligo from 1990 to 2021 at home and abroad. They are classified according to their structures and mechanisms of action, including natural products and derivatives, anti-oxidative stress drugs, immunosuppressants, prostaglandins, etc. The research on their anti-vitiligo activity, structural modification, new dosage forms, clinical trials, and the development trend in new anti-vitiligo drugs are reviewed, which provides important references for the development of new drugs.

Indian J Dermatol Venereol Leprol 2021; 88:32-39. [PMID: 34379960 DOI: 10.25259/ijdvl_928_20] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Accepted: 04/01/2021] [Indexed: 11/04/2022]
Abstract
BACKGROUND Vitiligo places a significant psycho-social burden on caregivers and family members. AIMS The aim of the study was to develop and preliminarily validate a scale to measure the psychosocial impact of vitiligo on adult family members. METHODS Themes that emerged from qualitative interviews and a focus group discussion with family members were used to generate items for a preliminary scale, followed by pre-testing and scale development. The new scale was then tested with two comparator scales and a global question. RESULTS A preliminary scale with 32 items was pilot tested on 30 participants. Following this, the scale was condensed to 16 items in 12 domains that were administered to 159 participants. Scale scores ranged from 0 to 48 with a mean of 19.75 ± 12.41. The scale had excellent internal consistency with Cronbach's alpha coefficient of 0.92 (0.70-0.95) and also showed good test-retest reliability at two weeks (r = 0.946). The scale showed criterion, convergent and known group validity. LIMITATIONS It was conducted in a large teaching hospital which may have resulted in selection of patients with persistent or progressive disease and more worried family members. Vitiligo is highly stigmatized in our country and the performance of the scale may need to be evaluated in other communities and cultures as well where stigma is less oppressive. CONCLUSION Family Vitiligo Impact Scale appears to be an easy-to-complete, reliable and valid instrument to measure the psychosocial impact of vitiligo in family members of patients. It may be useful as an outcome measure in both clinical and research settings.

Abstract
Psoriasis is an autoimmune skin disorder characterized by hyper proliferation and poor differentiation of keratinocytes. It significantly affects patient's quality of life. This study reports the anti-psoriatic efficacy of tacrolimus and curcumin loaded liposphere gel formulation. Poor solubility, poor skin penetration and erratic absorption are some problems associated with the topical delivery of these drugs. To overcome these problems, lipospheres containing combination of tacrolimus and curcumin was prepared with a particle size of nearly 50nm and incorporated into a gel for topical application. Liposphere gel showed slow release of both the drugs and shear thinning behaviour that is desirable property of topical formulation. Further, dermal distribution study using dye loaded formulation suggested penetration of dye into skin layers. The therapeutic efficacy of tacrolimus and curcumin loaded liposphere gel was assessed on imiquimod induced psoriatic plaque model, and the level of expression of psoriatic biochemical markers was evaluated using enzyme-linked immunosorbent assay. Results indicated improvement in the phenotypic and histopathological features of psoriatic skin treated with tacrolimus and curcumin loaded liposphere gel. There was reduction in the level of TNF-α, IL-17 and IL-22 compared to imiquimod group. These results corroborate the premise that liposphere gel containing combination of tacrolimus and curcumin can be an effective strategy for the treatment of psoriasis.

Abstract
Vitiligo is an acquired pigmentary disorder, clinically characterized by depigmented macules caused by destruction of melanocytes in the affected skin. Half of all patients develop the disease in childhood and adolescence before the age of 20 years, making vitiligo an important skin disease of childhood. There are numerous studies in the literature that suggest the efficacy of topical tacrolimus in vitiligo, without serious adverse effects. We describe a case of vitiligo in a pediatric patient who developed hyperpigmentation in the periorbital lesions of vitiligo with the use of topical tacrolimus. To the best of our knowledge, this is only the second such reported occurrence in a patient with vitiligo.

Abstract
Vitiligo is a common depigmenting skin disorder, characterized by acquired, idiopathic, progressive, circumscribed hypomelanosis of the skin and hair, with total absence of melanocytes microscopically. It occurs worldwide, with an incidence rate of between 0.1% and 2%. Vitiligo is an important skin disease having a major impact on the quality of life of the patient suffering from it. The causes of this condition are uncertain but seem to be dependent on the interaction of genetic, immunological and neurological factors. Vitiligo coexists with other autoimmune disorders, Sutton or halo nevus, and malignant melanoma. The substantial disfigurement associated with vitiligo can cause serious emotional stress for the patient, which necessitates treatment. Because its pathogenesis is still not understood, there is a plethora of different treatments. Among them, topical steroids and narrowband ultraviolet B monotherapy were the most common as current treatments for localized and generalized vitiligo, respectively. Cosmetic improvement can be achieved by camouflage products and self-tanning dyes. The course of vitiligo is unpredictable, but often progressive. Spontaneous repigmentation may occur in a few people (10–20%), mainly in children, but this tends to be only partial and on sun-exposed areas. In this article, we review vitiligo as a whole, including epidemiology, pathogenesis and etiology, histopathology, clinical manifestations, classification, clinical variants, diagnosis and differential diagnoses, specific investigation, treatment, prognosis, psychosocial view and its association with other disorders.

Abstract
BACKGROUND Vitiligo is a chronic disease that mostly affects children and young adults. Nowadays many treatment options are available; however, most of them have limited efficacy and in most cases would result in undesirable complications. OBJECTIVE To determine the extent of repigmentation according to the location of the lesions after applying topical cream pimecrolimus 1% in vitiligo patients. MATERIALS AND METHODS Thirty consecutive patients with vitiligo lesions affecting less than 20% of body surface area without any previous history of spontaneous repigmentation were treated with pimecrolimus cream 1% twice daily for 12 weeks. The extent of repigmentation in vitiligo lesions was determined in each patient after 6 and 12 weeks. RESULTS Moderate to excellent response (repigmentation >26%) was observed in 6.6 and 25.9% of vitiligo lesions 6 and 12 weeks after treatment, respectively. More responsive lesions were located on the trunk, face and elbow (85.7, 75 and 70%). CONCLUSION Pimecrolimus cream 1% results in repigmentation in vitiligo in different extents according to the location of the lesion; however, to clearly prove its efficacy as monotherapy or in combination with other available treatment options, double-blind placebo-controlled studies are essential.

Abstract
Tacrolimus ointment (Protopic) is a topically applied macrolide lactone immunomodulator effective in the treatment of atopic dermatitis. Its mechanism of action primarily involves calcineurin inhibition, which interrupts cytokine gene expression and leads to the downregulation of T-cell activity. Tacrolimus ointment (0.03% and 0.1% for adults and 0.03% for children) is an effective treatment for atopic dermatitis of the trunk and limbs, as well as sensitive skin areas such as the face. Its efficacy is similar to or greater than that of hydrocortisone acetate 1%, hydrocortisone butyrate 0.1% and betamethsone valerate 0.12% ointments and pimecrolimus 1% cream. Systemic absorption of tacrolimus from the ointment is minimal, and adverse events, which are mostly associated with the application site and include skin burning and pruritus, tend to resolve early in treatment. Unlike topical corticosteroids, tacrolimus ointment is not associated with skin atrophy, and it is a well tolerated treatment for adults or children with atopic dermatitis, particularly when long-term treatment is indicated or the face or skin-fold regions are involved.

Abstract
Childhood vitiligo is a common disorder of pigmentation in India. Considering the lack of uniformly effective and safe treatment modalities for children with vitiligo, search for newer therapeutic agents continues. This study was designed to evaluate the role of topical tacrolimus in the treatment of childhood vitiligo. Twenty-five children with vitiligo were treated with topical 0.03% tacrolimus ointment applied twice daily for 12 weeks. Response was noted as marked to complete (> 75% repigmentation), moderate (50-75% repigmentation) and mild (< 50% repigmentation). Twenty-two children (9 boys and 13 girls) of mean age 7.2 +/- 1.4 years completed the study. Twelve (54.5%) children had vitiligo vulgaris, nine (40.9%) had focal vitiligo and one (4.5%) had segmental vitiligo. The mean duration of disease was 8 +/- 3 months. Nineteen (86.4%) children showed some repigmentation at the end of 3 months and other three had no response. Of these 19 children, repigmentation was marked to complete in 11 (57.9%), moderate in five (26.3%) and mild in three (15.7%) children. Side effects were minimal, such as the pruritus and burning noted in only three patients. Topical tacrolimus is an effective and well-tolerated treatment modality in Asian children with vitiligo.
