Abstract
BACKGROUND Vitiligo is a common autoimmune skin disease. Capsaicin has been found to exert a positive effect on vitiligo treatment, and mesenchymal stem cells (MSCs) are also confirmed to be an ideal cell type. This study aimed to explore the influence of capsaicin combined with stem cells on the treatment of vitiligo and to confirm the molecular mechanism of capsaicin combined with stem cells in treating vitiligo. METHODS AND RESULTS PIG3V cell proliferation and apoptosis were detected using CCK-8 and TUNEL assays, MitoSOX Red fluorescence staining was used to measure the mitochondrial ROS level, and JC-1 staining was used to detect the mitochondrial membrane potential. The expression of related genes and proteins was detected using RT‒qPCR and Western blotting. Coimmunoprecipitation was used to analyze the protein interactions between HSP70 and TLR4 or between TLR4 and mTOR. The results showed higher expression of HSP70 in PIG3V cells than in PIG1 cells. The overexpression of HSP70 reduced the proliferation of PIG3V cells, promoted apoptosis, and aggravated mitochondrial dysfunction and autophagy abnormalities. The expression of HSP70 could be inhibited by capsaicin combined with MSCs, which increased the levels of Tyr, Tyrp1 and DCT, promoted the proliferation of PIG3V cells, inhibited apoptosis, activated autophagy, and improved mitochondrial dysfunction. In addition, capsaicin combined with MSCs regulated the expression of TLR4 through HSP70 and subsequently affected the mTOR/FAK signaling pathway CONCLUSIONS: Capsaicin combined with MSCs inhibits TLR4 through HSP70, and the mTOR/FAK signaling pathway is inhibited to alleviate mitochondrial dysfunction and autophagy abnormalities in PIG3V cells.

[PMID: 38485678 DOI: 10.2174/0115680266277952240223120435] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 12/30/2023] [Accepted: 01/11/2024] [Indexed: 07/16/2024]
Abstract
Frequently occurring inflammatory skin conditions such as psoriasis, dermatitis, acne, including skin cancer, wounds and other disorders arising out of premature skin aging, deteriorate skin health and adversely impact human life. Even though several synthetic compounds have evolved for treating these skin conditions, natural-product-based therapeutics are gaining popularity with growing evidence of their efficacy and safety for treating skin disorders. Many of these inflammatory skin diseases have underlying disturbances in our immune system and immunomodulatory natural products provide solutions for their effective treatment and aid in understanding the underlying mechanism of such inflammatory skin conditions. Based on this premise, the present review summarizes the possible application of plant-derived immunomodulatory compositions and single molecules for treating inflammatory skin conditions. In vitro, in vivo and mechanistic studies reported the application of selected plant-derived natural products for the treatment of inflammatory skin disorders including, cancer and infections. Several online databases including PubMed, Google Scholar, and Science Direct have been searched for gathering the information covered in this review. Empirical studies demonstrated that most of these natural compounds exhibited therapeutic properties through their immunomodulatory and anti-inflammatory potential supplemented often with anti-microbial, anti-neoplastic, and anti- oxidant activities. Overall, plant-based natural products discussed here are capable of modulating the immune system to minimize or completely suppress the pro-inflammatory markers, scavenge free radicals (ROS), prevent bacteria, fungal, and virus-derived skin infections and often regress skin cancer through the induction of apoptosis. The challenges and opportunities associated with the application of plant-based immunomodulators for skin applications and their safety considerations are also discussed here. The present study indicated that immunomodulatory plant natural products being biologically validated ligands against various biological targets manifested in inflammatory skin diseases, offer an effective, safe and affordable treatment for such disorders affecting skin health. However, further clinical evaluations are needed to substantiate these findings.

Abstract
Vitiligo is a chronic disease of unknown etiology that causes progressive cutaneous depigmentation. Current pharmacological treatments have limited success and present significant risks. Many efforts have been made in recent years to explore new anti-vitiligo therapeutic strategies, including herbal-based therapies. The objective of the present review is to provide an updated overview on the most frequently used medicinal plants in the treatment of vitiligo. A bibliographical search was carried out in scientific databases Pubmed, Scifinder, Scopus, Google Scholar, and Medline up to October 2021 using the descriptors vitiligo, herbal, medicinal plants, and alternative therapies. In our search, the highest number of published studies comprise plants commonly used in traditional herbal medicine, highlighting the usefulness of ethnopharmacology in the discovery of new therapeutic agents. The review outlines current understanding and provides an insight into the role of psoralens and khellin (photosensitizing agents obtained from plants such as Cullen corylifolium or Ammi visnaga). The paper also describes other traditional herbs such as Ginkgo biloba, Phlebodium aureum, Piper nigrum, Picrorhiza kurroa, and Baccharoides anthelmintica that can likewise act as potential therapeutical agents. Based on our findings, photosensitizing agents in combination with phototherapy, the association of oral Phebodium aureum with phototherapies as well as oral G. biloba in monotherapy showed greater scientific evidence as therapeutic options. The research results emphasize that further investigation in this area is merited. More long-term follow up clinical trials and higher quality randomized trials are needed.

Abstract
Vitiligo is characterized by the development of depigmented macules and patches. Autoimmunity has been established as a factor in disease pathogenesis, leading to utilization of immunosuppressive agents. Topical immunosuppressants are commonly used; however, this treatment modality is often cumbersome and inefficient, as many patients have active disease with extensive body surface area involvement. Prompt and aggressive treatment of vitiligo is important, as this may prevent progression and improve quality of life. To meet these challenges and improve patient outcomes, interest in systemic therapies has grown. Currently, oral therapies are rarely prescribed, likely due to concerns with systemic side effects and unclear efficacy. This article provides a brief overview on the use of systemic agents in treating vitiligo in order to provide additional therapeutic options to clinicians.

Medicina (B Aires) 2023; 59:medicina59030427. [PMID: 36984427 PMCID: PMC10053937 DOI: 10.3390/medicina59030427] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 02/18/2023] [Accepted: 02/20/2023] [Indexed: 02/24/2023] Open
Abstract
Background and Objectives: Vitiligo is a skin disorder characterized by hypopigmented macules occurring due to melanocyte destruction. An interplay of several biochemical mechanisms has been proposed to explain the etiopathogenesis of vitiligo, such as genetic, autoimmune responses, generation of inflammatory mediators, oxidative stress, and melanocyte detachment mechanisms. There is no cure for vitiligo; however, pharmacological treatment measures (cosmetic camouflage creams, steroids, psoralen and ultraviolet A (PUVA) therapy, narrowband UVB) are available, but they could have certain side effects. We reported an interesting case of vitiligo in Saudi Arabia that showed reversal of vitiligo, which is an extremely rare phenomenon, with the objective of probing the probable reasons for this reversal. To the best of our knowledge, there is no study on vitiligo that has reported spontaneous reversal of vitiligo in Saudi Arabia so far. Materials and Method: The patient presented to the Family Medicine clinic with a history of restoration of melanin pigment in his lesions after 3 years of the onset of vitiligo. Patients history was taken carefully along with clinical examination, carried out necessary biomedical lab investigations and compiled the data. The data at the time of pigment restoration were compared to the previous data when he developed the lesions. Result: The probable reasons for vitiligo reversal could be markedly decreased psychological stress, regular consumption of an antioxidant-rich herbal drink made of curcumin and honey, and dietary switchover to vegetarianism and an alcohol-free lifestyle. Conclusions: Curcumin-based herbal remedies could be an alternative option to treat vitiligo. These methods must be further explored through clinical trials as they are safer, easily available, and more affordable.

Abstract
BACKGROUND Vitiligo is a common depigmentation skin disease that affects the quality of life in many patients. AIMS This study aims to investigate the effect of Medicago sativa methanol extract on the treatment of skin hypopigmentation disorders. METHODS Antioxidant activity and phytochemical constituents of the extract were determined using DDPH assay, Folin-Ciocalteu, AlCl3, and HPLC-MS/MS analysis. Oil in water (o/w) creams were prepared to contain the methanolic extract, and applied to hydroquinone-induced depigmentation in vivo model and further challenged in combination with UVA light exposure. Skin and hair colors were visually scored and evaluated at different time intervals, and histopathological examinations of skin layers and hair follicles were performed. RESULTS A total phenolic content of 187.70 mg/g, equivalent to gallic acid, and total flavonoid content of 21.97 mg/g, equivalent to quercetin, were recorded. Extract showed 71% antioxidant activity. Moreover, the HPLC-MS/MS detection revealed the presence of 18 compounds including P-coumaric acid and antioxidants flavonoids, of those are seven compounds not previously detected in this species. The in vivo study showed a remarkable skin and hair pigmentation effect on plant extract-treated groups, compared to the reference, placebo, and control groups. Histopathological examinations showed the growth of colored hair follicles in the dermis and epidermis layers of the extract-treated mice. CONCLUSION The study suggests the use of M. sativa extract in enhancing the pigmentation process in hypopigmented skin and hair if combined with UVA light. Therefore, M. sativa extract can be considered a potential treatment for vitiligo.

Abstract
Vitiligo is a complex disorder with an important effect on the self-esteem and social life of patients. It is the commonest acquired depigmentation disorder characterized by the development of white macules resulting from the selective loss of epidermal melanocytes. The pathophysiology is complex and involves genetic predisposition, environmental factors, oxidative stress, intrinsic metabolic dysfunctions, and abnormal inflammatory/immune responses. Although several therapeutic options have been proposed to stabilize the disease by stopping the depigmentation process and inducing durable repigmentation, no specific cure has yet been defined, and the long-term persistence of repigmentation is unpredictable. Recently, due to the progressive loss of functional melanocytes associated with failure to spontaneously recover pigmentation, several different cell-based and cell-free regenerative approaches have been suggested to treat vitiligo. This review gives an overview of clinical and preclinical evidence for innovative regenerative approaches for vitiligo patients.

Abstract
Melanin pigment produced in melanocytes plays a protective role against ultraviolet radiation. Selective destruction of melanocytes causes chronic depigmentation conditions such as vitiligo, for which there are very few specific medical treatments. Here, we found that fraxinol, a natural coumarin from Fraxinus plants, effectively stimulated melanogenesis. Treatment of B16-F10 cells with fraxinol increased the melanin content and tyrosinase activity in a concentration-dependent manner without causing cytotoxicity. Additionally, fraxinol enhanced the mRNA expression of melanogenic enzymes such as tyrosinase, tyrosinase-related protein-1, and tyrosinase-related protein-2. Fraxinol also increased the expression of microphthalmia-associated transcription factor at both mRNA and protein levels. Fraxinol upregulated the phosphorylation of cyclic adenosine monophosphate (cAMP) response element-binding protein (CREB). Furthermore, H89, a cAMP-dependent protein kinase A inhibitor, decreased fraxinol-induced CREB phosphorylation and microphthalmia-associated transcription factor expression and significantly attenuated the fraxinol-induced melanin content and intracellular tyrosinase activity. These results suggest that fraxinol enhances melanogenesis via a protein kinase A-mediated mechanism, which may be useful for developing potent melanogenesis stimulators.

Abstract
Phenolic compounds are a large, heterogeneous group of secondary metabolites found in various plants and herbal substances. From the perspective of dermatology, the most important benefits for human health are their pharmacological effects on oxidation processes, inflammation, vascular pathology, immune response, precancerous and oncological lesions or formations, and microbial growth. Because the nature of phenolic compounds is designed to fit the phytochemical needs of plants and not the biopharmaceutical requirements for a specific route of delivery (dermal or other), their utilization in cutaneous formulations sets challenges to drug development. These are encountered often due to insufficient water solubility, high molecular weight and low permeation and/or high reactivity (inherent for the set of representatives) and subsequent chemical/photochemical instability and ionizability. The inclusion of phenolic phytochemicals in lipid-based nanocarriers (such as nanoemulsions, liposomes and solid lipid nanoparticles) is so far recognized as a strategic physico-chemical approach to improve their in situ stability and introduction to the skin barriers, with a view to enhance bioavailability and therapeutic potency. This current review is focused on recent advances and achievements in this area.

Abstract
Vitiligo is an acquired pigmentary disorder afflicting 0.5-2% of the world population for both sexes and all races with a capricious and unpredictable course. It has a complex etiology and varies in its manifestation, progression and response to treatment. Even if the precise aetiology and pathobiology of the disease are complex and still debated, recent evidence supports that vitiligo is a T CD8+ cell-mediated autoimmune disease triggered by oxidative stress. To date no clinical, biological and histological criteria allow us to establish the prognosis with certainty. The choice of the best therapy for adult and childhood vitiligo is based on various factors, such as the patient's age, psychological condition and expectations, distribution and extension of skin lesions, type of vitiligo (stable or not) and availability and cost of therapeutic options. Since vitiligo has a deep psychological impact on patients and their quality of life, treating the disease is very important. As dermatologists, we have important goals in the treatment of vitiligo patients: stabilization of the disease progression, repigmentation of the lesions and especially the persistence of the aforementioned repigmentation. Although several medical and surgical therapeutic options have been proposed, no definite cure has yet been developed and the long-term persistence of repigmentation is unpredictable. We review the different therapeutic options with particular attention on the recurrence rate.

However, liver injury caused by PF and its preparations has been frequently reported in recent years. Our previous studies have demonstrated that PF could cause idiosyncratic drug-induced liver injury (IDILI), but the mechanism underlying its hepatotoxicity remains unclear. This paper reports that bavachin isolated from PF enhances the specific stimuli-induced activation of the NLRP3 inflammasome and leads to hepatotoxicity. Bavachin boosts the secretion of IL-1β and caspase-1 caused by ATP or nigericin but not those induced by poly(I:C), monosodium urate crystal, or intracellular lipopolysaccharide. Bavachin does not affect AIM2 or NLRC4 inflammasome activation. Mechanistically, bavachin specifically increases the production of nigericin-induced mitochondrial reactive oxygen species among the most important upstream events in the activation of the NLRP3 inflammasome. Bavachin increases the levels of aspartate transaminase and alanine aminotransferase in serum and hepatocyte injury accompanied by the secretion of IL-1β via a mouse model of lipopolysaccharide-mediated susceptibility to IDILI. These results suggest that bavachin specifically enhances the ATP- or nigericin-induced activation of the NLRP3 inflammasome. Bavachin also potentially contributes to PF-induced idiosyncratic hepatotoxicity. Moreover, bavachin and PF should be evaded among patients with diseases linked to the ATP- or nigericin-mediated activation of the NLRP3 inflammasome, which may be a dangerous factor for liver injury.

Abstract
BACKGROUND Vitiligo is a hypopigmentation disorder that affects 1% of the world's population. Vitiligo causes white spots on the skin, mucous membranes, or white hair by destroying skin melanocytes. The pathogenesis of vitiligo is unknown but autoimmune, autocytotoxic, and neural mechanisms are suggested. According to the autoimmune theory, in people with vitiligo, immune cells invade and damage melanocytes. T cells are more commonly present in vitiligo patients' skin and remain in the lesion site, which is composed of CD8 and CD4 T cells. Many studies have been conducted on the presence and role of cytokines such as interleukins and interferongamma (IFN-γ) in the vitiligo process. AIM This study aimed to introduce herbs effective against vitiligo from the perspective of Persian medicine and to investigate their possible therapeutic mechanisms with the possible effects of herbs on autoimmune mechanisms. METHODS For this purpose, keywords were used to extract data from Persian medicine textbooks, and then relevant scientific databases, including Google Scholar, PubMed, Web of Science, and Scopus were examined. RESULTS It was found that Persian medicine scholars used 50 different medicinal plants to treat and reduce the complications of vitiligo, and recent scientific studies have proven immune-regulating properties and reducing the effect of many of them on cytokines. CONCLUSION According to scientific evidence on immunomodulatory effects, new research into the effects of these plants on vitiligo can lead to the discovery of new drugs and approaches for treating this disease.

Abstract
Vitiligo is a common congenital or acquired disfiguring skin disorder. At present, endoplasmic reticulum (ER) stress has been identified to serve a critical role in the pathogenesis of vitiligo. Receptor-interacting serine/threonine-protein kinase 1 (RIPK1) is a protein serine/threonine kinase. The specific molecular mechanism of RIPK1 in human melanocytes upon ER stress remains to be determined. In the present study, RIPK1 was significantly downregulated in tunicamycin (TM)-induced ER stressed-human melanocytes. Subsequently, to explore the role of RIPK1 in ER stress-induced human melanocytes, human melanocytes were transfected with control or RIPK1 plasmids for 24 h and then treated with 3 µM TM for 48 h. Reverse transcription-quantitative PCR and western blot analysis indicated that the expression levels of protein kinase R-like endoplasmic reticulum kinase, eukaryotic translation initiation factor 2 subunit 1 and CCAAT-enhancer-binding protein homologous protein were significantly increased in the TM-treated group compared with the controls. In addition, the effect of high RIPK1 expression on ER stress-induced human melanocyte survival was studied. The present results indicated that TM inhibited cell viability and promoted apoptosis in human primary epidermal melanocytes. Western blot analysis demonstrated that the expression of Bax and caspase-3 was upregulated and the expression of Bcl-2 was downregulated in TM-treated human melanocytes. The effects of TM on human melanocytes were reversed by RIPK1 overexpression. Therefore, RIPK1 overexpression may have an effect on the PI3K/AKT/mTOR signaling pathway in human melanocytes under ER stress. The results of the current study demonstrated that RIPK1 could protect human melanocytes from cell damage induced by ER stress by regulating the PI3K/AKT/mTOR and ER stress signaling pathways, thereby serving a protective role in the occurrence and development of vitiligo.

Abstract
Vitiligo is a common localized or generalized skin pigmentation disorder. Endoplasmic reticulum (ER) stress may be implicated in the development of vitiligo. microRNA-421 (miR-421) has been reported to be dysregulated in various human tumors. However, there is no report to date on the role of miR-421 in vitiligo development. The present study demonstrated that 3 µM tunicamycin (TM) increased the expression of the ER stress-related proteins protein kinase RNA-like endoplasmic reticulum kinase (PERK), α subunit of eukaryotic translation initiation factor 2 (eIF2α) and C/EBP homologous protein (CHOP) in human primary epidermal melanocytes. Moreover, TM suppressed melanocyte viability and induced apoptosis. Reverse transcription-quantitative PCR analysis demonstrated that TM promoted miR-421 expression in human melanocytes. Next, TargetScan and dual luciferase reporter gene assay indicated that receptor-interacting serine/threonine kinase 1 (RIPK1) was a direct target of miR-421. RIPK1 expression was significantly downregulated in TM-induced human melanocytes. Subsequently, the effect of miR-421 downregulation on the damage of human melanocytes induced by ER stress was investigated. Human melanocytes were transfected with inhibitor control, miR-421 inhibitor, miR-421 inhibitor + control-short hairpin (sh)RNA, or miR-421 inhibitor + RIPK1-shRNA for 24 h and then treated with TM (3 µM) for 48 h. TM was found to upregulate PERK, eIF2α and CHOP protein expression in human melanocytes, which was reduced by an miR-421 inhibitor. In addition, the miR-421 inhibitor increased viability and reduced apoptosis in TM-treated melanocytes. Furthermore, all these effects of the miR-421 inhibitor on TM-induced human melanocytes were reversed by RIPK1-shRNA. Further analyses revealed that the miR-421 inhibitor activated the phosphoinositide 3 kinase/protein kinase B/mammalian target of rapamycin signaling pathway in TM-induced human melanocytes. These data collectively suggest that miR-421 may serve as a new treatment target in vitiligo development.

A Network Pharmacology Approach to Uncover the Molecular Mechanisms of Herbal Formula Kang-Bai-Ling for Treatment of Vitiligo. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:3053458. [PMID: 31781265 PMCID: PMC6875403 DOI: 10.1155/2019/3053458] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/08/2019] [Revised: 09/15/2019] [Accepted: 10/04/2019] [Indexed: 12/19/2022]
Abstract
Background Kang-bai-ling (KBL), a Chinese patent medicine, has been demonstrated as an effective therapy for vitiligo in China. However, the pharmacological mechanisms of KBL have not been completely elucidated. Methods In this study, the potential multicomponent, multitarget, and multipathway mechanism of KBL against vitiligo was clarified by using network pharmacology-based strategy. In brief, potential targets of KBL were collected based on TCMSP databases, followed by network establishment concerning the interactions of potential targets of KBL with well-known therapeutic targets of vitiligo by using protein-protein interaction (PPI) data. As a result, key nodes with higher level of seven topological parameters, including “degree centrality (DC),” “betweenness centrality (BC),” “closeness centrality (CC),” “eigenvector centrality (EC),” “network centrality (NC),” and “local average connectivity (LAC)” were identified as the main targets in the network, followed by subsequent incorporation into the ClueGO for GO and KEGG signaling pathway enrichment analysis. Results In accordance with the topological importance, a total of 23 potential targets of KBL on vitiligo were identified as main hubs. Additionally, enrichment analysis suggested that targets of KBL on vitiligo were mainly clustered into multiple biological processes (associated with DNA translation, lymphocyte differentiation and activation, steroid biosynthesis, autoimmune and systemic inflammatory reaction, neuron apoptosis, and vitamin deficiency) and related pathways (TNF, JAK-STAT, ILs, TLRs, prolactin, and NF-κB), indicating the underlying mechanisms of KBL on vitiligo. Conclusion In this work, we successfully illuminated the “multicompounds, multitargets” therapeutic action of KBL on vitiligo by using network pharmacology. Moreover, our present outcomes might shed light on the further clinical application of KBL on vitiligo treatment.

Abstract
Vitiligo is a pigment disease characterized by the disruption of melanocyte structure and function. Its etiology is unknown; however, genetic predisposition, biochemical factors, and neural mechanisms are thought to be effective. Although many agents are being used for its treatment, generally there is no absolute cure. The aim of the present study is to evaluate the effectiveness of topical Nigella sativa seed oil on vitiligo patients. Thirty-three vitiligo patients were included in the study. Totally 47 areas were evaluated in all patients. Cream containing N sativa seed oil was topically applied to hands, face, and genital region two times a day for 6 months. Statistically significant repigmentation was detected in hands, face, and genital region, the three treatment areas, and the p values are found .005, .001, and .004, respectively. N sativa can be used as an adjuvant therapy that can contribute to the treatment especially in sensitive skin areas like genital region.

Abstract
Background Fructus Psoraleae is the seed of Psoralea corylifolia Linn. Fructus Psoraleae has been shown to be effective in treating some skin diseases, such as vitiligo. As a main ingredient in five types of herbs in the Qubaibabuqi tablet formula, Fructus Psoraleae plays an important role in the treatment of vitiligo. Fructus Psoraleae has potential hepatotoxicity, thus Qubaibabuqi tablets also have potential liver toxicity. Case presentation A 53-year-old woman who was diagnosed with vitiligo in September 2017 was treated with Qubaibabuqi tablets. After approximately 7 months of treatment, the patient developed a severe, diffuse yellow staining of the skin and sclera in March 2018. On admission, she was diagnosed with acute cholestatic hepatitis associated with Fructus Psoraleae. Despite receiving active treatment, her condition rapidly deteriorated and she died 5 days later due to acute liver failure and multiple organ dysfunction. To the best of our knowledge, there are only six reported cases of liver injury associated with Fructus Psoraleae described in the English language literature; however, cases of acute liver failure associated with the use of Fructus Psoraleae have not been described. Conclusion As a main ingredient in the Qubaibabuqi tablet formula, Fructus Psoraleae has potential hepatotoxicity. This potentially fatal adverse effect should be considered when physicians prescribe Qubaibabuqi tablets.

Abstract
BACKGROUND Vitiligo is an acquired pigmentary disease, that causes progressive loss of melanocytes, resulting in hypopigmented skin patches. Current treatments aim at stopping the disease progression and achieving repigmentation of the amelanotic areas. Corticosteroids, surgery, topical immunomodulators, total depigmentation of normal pigmented skin and phototherapy are current treatment options for vitiligo although phototherapy remains the treatment of choice. There is no documented evidence that herbal bio-active products may also be effective treatment options for vitiligo. AIM This study aimed to investigate the efficacy and safety of Vitilinex® (herbal bio- actives) alone and in combination with UVB narrowband (311 nm) phototherapy, in the treatment of localised stable or active forms of vitiligo. MATERIAL AND METHODS Sixty two subjects with mean age 34.5 years (range: 18-58 years) with mild to moderate vitiligo, consisting of 36 females and 26 males were randomly divided into three treatment groups - Group A (13 females, 10 males) treated with Vitilinex® alone; Group B (12 females, 11 males) were treated with Vitilinex® in combination with narrowband UVB (311 nm) phototherapy for 15 seconds, using a handheld lamp and Group C (8 females, 8 males) were treated with nbUVB (311 nm) phototherapy alone, for 15 seconds over a 12-week period. RESULTS In Group A, 9 patients (39%) achieved outstanding improvement with a re-pigmentation rate higher than 75%, with 2 patients experiencing total repigmentation. 6 patients (26%) had marked improvement with a repigmentation rate between 50-75% while 5 patients (22%) showed a moderate response between 25-50% re-pigmentation rate. 3 patients (13%) had minimal or no improvement. In Group B, 16 patients (69.5%) achieved outstanding improvement with a re-pigmentation rate higher than 75%, with 12 patients experiencing total re-pigmentation. 4 patients (17.5 %) achieved a marked improvement with a re-pigmentation rate between 50-75%; 2 patients (8.7%) showed a moderate response with a re-pigmentation rate between 25-50%. 1 (4.3%) patient had minimal or no improvement. In Group C, 6 patients (37.5%) achieved a re-pigmentation rate higher than 75%, with 2 patients experiencing total re-pigmentation. 4 patients (25%) achieved marked improvement with a re-pigmentation rate between 50-75% while 3 patients (18.75%) had a re-pigmentation rate between 25-50%. 3 patients (18.75%) had minimal or no improvement. CONCLUSION Vitilinex® herbal bio-actives in combination with nbUVB is a more effective treatment option for vitiligo with 87% of the patients achieving a re-pigmentation rate higher than 50%, compared to Vitilinex® alone (65%) or nbUVB alone (62.5%).
