Objectives : The aim of this study is to review the effect of acupuncture/moxibustion on vitiligo. Methods : Using 5 databases(Pubmed, EMBASE, Cochrane Library, RISS, OASIS) clinical studies about effect of acupuncture/moxibustion on vitiligo were searched. Only randomized controlled trials(RCTs) were selected to analyze. Results : Total 235 studies were searched. After screening those studies 5 studies were selected from china and Iran. 3 studies used effective rate to measure the effect of acupuncture for vitiligo. 1 study used Vitiligo Area Scoring Index(VASI) and 1 study assessed 4 grade of repigmentation to prove acupuncture's effect on vitiligo. All studies showed repigmentation in acupuncture/moxibustion group. Adverse effects reported in the five studies were temporary erythema, itching, and dryness. Conclusions : These findings suggest that acupuncture and moxibustion can be considered a safe treatment for vitiligo. However, due to the small number of RCTs conducted on acupuncture and moxibustion for vitiligo, more RCTs should be conducted to confirm the effectiveness of acupuncture and moxibustion for vitiligo.

Oxidative stress-induced melanocyte apoptosis is linked to the immune system and plays a critical role in the pathogenesis of vitiligo. Aquaporin-3 (AQP3), which is downregulated in vitiligo keratinocytes, regulates intracellular H₂O₂ accumulation. However, the role of AQP3 in oxidative stress is uncertain in vitiligo. This study investigated the effect of downregulated AQP3 on oxidative stress in vitiligo using lesional and non-lesional skin specimen sets from vitiligo patients and primary cultured adult normal human epidermal keratinocytes, with or without downregulation and overexpression of AQP3 in the presence or absence of H₂O₂ treatment. The levels of nuclear factor E2-related factor 2 (NRF2) and/or its main target, NAD(P)H quinone dehydrogenase 1 (NQO-1), were lower in the lesional keratinocytes and cultured keratinocytes with AQP3 knockdown, but were increased in keratinocytes upon AQP3 overexpression. Ratios of NRF2 nuclear translocation and NQO-1 expression levels were further reduced in AQP3-knockdown keratinocytes following H₂O₂ treatment. The conditioned media from AQP3-knockdown keratinocytes treated with H₂O₂ contained higher concentrations of reactive oxygen species (ROS). Moreover, the number of viable melanocytes was reduced when the conditioned media were added to the culture media. Overall, AQP3 downregulation in the keratinocytes of patients with vitiligo can induce oxidative stress in neighboring melanocytes, leading to melanocyte death.

Vitiligo is a multifactorial disorder. Neural, biochemical, and autoimmune mechanisms have been hypothetically suggested as etiopathological contributors to this condition. Autoimmunity focuses primarily on genetic factors and the association between vitiligo and other autoimmune disorders including autoimmune thyroid disease, rheumatoid arthritis, psoriasis, type 1 diabetes, pernicious anemia, and Addison's disease. We describe a 35-year-old man with systemic lupus erythematosus who developed concurrent vitiligo and discoid lupus erythematosus suggesting the possible autoimmune association between these 2 different diseases.

Background: Vitiligo is a chronic autoimmune disease in which the destruction of melanocytes causes white spots on the affected skin. Janus kinase (JAK) is a family of intracellular, non-receptor tyrosine kinases that transduce cytokine-mediated signals via the JAK-signal transducer and activator of transcription pathway. The aim of the present study is to explore the possible role of JAK1 in the pathogenesis of vitiligo using immunohistochemical methods. Methods: The current study was conducted in a sample of 39 patients who presented with vitiligo and 22 healthy individuals who were age and sex matched as a control group. We used immunohistochemistry to evaluate JAK1 status (intensity and distribution) and assess the percentage of residual melanocytes using human melanoma black 45 (HMB45). Results: Intense and diffuse JAK1 expression was significantly more likely to indicate vitiliginous skin compared to normal skin (p<.001). Strong and diffuse JAK1 expression was associated with short disease duration, female sex, and lower percentage of melanocytes (detected by HMB45) (p<.05). Conclusions: JAK1 may be involved in the pathogenesis of vitiligo, as indicated by intense and diffuse expression compared to control and association with lower percentage of melanocytes detected by HMB45 immunostaining.

In this study, the new color image processing algorithms with an android-based mobile device are developed to detect the abnormal color densities in a skin image and interpret them as the vitiligo lesions. Our proposed method is firstly based on transforming RGB data into HSI domain and segmenting the imag into the vitiligo-skin candidates by applying Otsu's threshold algorithm. The structure elements for morphological image processing are suggested to delete the spurious regions in vitiligo regions and the image blob labeling algorithm is applied to compare RGB color densities of the abnormal skin region with them of a region of interest. Our suggested color image processing algorithms are implemented with an android-platform smartphone and thus a mobile device can be utilized to diagnose or monitor the patient's skin conditions under the environments of pervasive healthcare services.

Vitiligo does not have a baneful influence on life and function of the body directly, but is a serious disease in that most patients suffer from difficulties in social life and considerable stress. We cured a vitiligo patient with a few depigmented patches in front of the left ear using aqua-acupuncture with hominis placenta and psoraleae fructus extract. Since this is just one case report, more case studies and research will be necessary.

Although a few reports have noted the concurrent presentation of morphea and vitiligo at distinctly separate sites in the same patient, it is extremely rare that these two conditions occur at the same sites in a patient. We report the case of a 10-year-old Korean girl with morphea and vitiligo and those lesions occurred at the same sites and progressed simultaneously. An autoimmunity and a cutaneous mosaicism was considered to be involved in such an unique presentation as the pathogenesis is concerned.

Vitiligo is a commonly acquired cutaneous depigmentation disorder that affects 0.5~1% of the population worldwide. While phototherapy is the primary treatment for vitiligo, surgical methods can be used for treating patients who are refractory to conventional treatments. Herein, we present the case of a 14-year-old Korean girl who developed vitiligo after hematopoietic stem cell transplantation for the treatment of acute lymphoblastic leukemia. She had multiple depigmented patches on her lower legs that did not respond to narrow-band ultraviolet B phototherapy for 7 months. The depigmented patches were successfully treated by transplantation of non-cultured epidermal cell suspension from the epidermal roof of the suction blister in the right inner thigh. No adverse event, such as secondary infection or scarring in both the donor and recipient sites, was noted. We recommended that non-cultured epidermal cell suspension transplantation using the suction blister method would be a safe and effective option for the treatment of refractory vitiligo.
