BACKGROUND: Various systemic agents have been assessed for the treatment of alopecia areata (AA); however, there is a paucity of comparative studies. OBJECTIVE: To assess and compare cyclosporine and betamethasone minipulse therapy as treatments for AA with regard to effectiveness and safety. METHODS: Data were collected from 88 patients who received at least 3 months of oral cyclosporine (n=51) or betamethasone minipulse therapy (n=37) for AA...

The hair follicle (HF) epithelium can present self-antigens to cognate CD8+ T cells. These cells express periodically during the hair cycle arising or age-related immunogenic proteins including HF-specific neo-antigens. We propose, that IFN-gamma derived from the respective antigen-specific T cells spotting the particular self-peptides may thereby significantly induce and alter self-antigen presentation ("induced-self"). This induction, at first, may silence T cells, including neo-epitope-specific T cells. As the thymus cannot significantly recapitulate neo-epitopes evolving in the periphery, we propose that peripheral tissue-specific induction of MHC molecules presenting exactly these neo-epitopes by self- MHC/peptide-reactive CD8+ T cells is a key element of self-tolerance...

Alopecia areata (AA) affects anagen hair follicles, resulting in non-scarring hair loss. Since introduced by Huang et al., superficial cryotherapy has been accepted as a considerable primary therapeutic modality for AA. The aim of this study was to objectively clarify the therapeutic efficacy and safety of superficial hypothermic cryotherapy for treatment of AA. Medical records of 353 patients from 1993 to 2014 were retrospectively analyzed. According to the response to the superficial cryotherapy, patients were categorized into four groups: "marked", "partial", "poor" and "no recovery"...

The recent interest and elucidation of the JAK/STAT signaling pathway created new targets for the treatment of inflammatory skin diseases (ISDs). JAK inhibitors in oral and topical formulations have shown beneficial results in psoriasis and alopecia areata. Patients suffering from other ISDs might also benefit from JAK inhibition. Given the development of specific JAK inhibitors, the expression patterns of JAKs in different ISDs needs to be clarified. We aimed to analyze the expression of JAK/STAT family members in a set of prevalent ISDs: psoriasis, lichen planus (LP), cutaneous lupus erythematosus (CLE), atopic dermatitis (AD), pyoderma gangrenosum (PG) and alopecia areata (AA) versus healthy controls for (p)JAK1, (p)JAK2, (p)JAK3, (p)TYK2, pSTAT1, pSTAT2 and pSTAT3...

Alopecia areata (AA) involves the immune-related destruction of hair follicles, resulting in patches of complete hair loss, most often on the scalp. The topical sensitizer squaric acid dibutylester (SADBE) is a popular treatment option given its low side-effect profile, hair regrowth potential, and lack of cross-reactivity with other chemicals. We describe a unique case of a 6-year-old girl who developed angioedema after SADBE treatment for AA.

BACKGROUND. Alopecia areata (AA) is a common autoimmune disease with a lifetime risk of 1.7%; there are no FDA-approved treatments for AA. We previously identified a dominant IFN-γ transcriptional signature in cytotoxic T lymphocytes (CTLs) in human and mouse AA skin and showed that treatment with JAK inhibitors induced durable hair regrowth in mice by targeting this pathway. Here, we investigated the use of the oral JAK1/2 inhibitor ruxolitinib in the treatment of patients with moderate-to-severe AA. METHODS...

BACKGROUND: Alopecia areata (AA) is an autoimmune disease characterized by hair loss mediated by CD8(+) T cells. There are no reliably effective therapies for AA. Based on recent developments in the understanding of the pathomechanism of AA, JAK inhibitors appear to be a therapeutic option; however, their efficacy for the treatment of AA has not been systematically examined. METHODS: This was a 2-center, open-label, single-arm trial using the pan-JAK inhibitor, tofacitinib citrate, for AA with >50% scalp hair loss, alopecia totalis (AT), and alopecia universalis (AU)...

BACKGROUND: Alopecia areata is a common hair loss disorder that results in patchy to complete hair loss. Many uncertainties exist around the most effective treatments for this condition. OBJECTIVES: To identify uncertainties in alopecia areata management and treatment that are important to both service users (people with hair loss, carers and relatives) and healthcare professionals. METHODS: An alopecia areata priority setting partnership was established between patients, their carers and relatives, and healthcare professionals to identify the most important uncertainties in alopecia areata...

BACKGROUND: Alopecia can be a manifestation of mycosis fungoides (MF); however, the prevalence is unknown. AIMS: We sought to describe the clinicopathologic presentation of alopecia in patients with diagnosis of MF. METHODS: A retrospective analysis of patients with biopsy-proven MF, who were evaluated at our cancer center from 2002 to 2012, was performed to identify patients with alopecia. RESULTS: Five patients with alopecia were identified from reviewing of 157 patients with MF...

Alopecia areata (AA) is a common hair loss disorder characterized by discrete, well demarcated areas of non-scarring terminal hair alopecia, with the calculated lifetime risk of ~2%. In past decades, linkage and GWA studies have implicated dozens of susceptibility genes/loci that are linked to the development of AA. Fischer et al performed a genome-wide CNV analysis of 585 AA patients and 1,340 controls in a European population. This is the first genome-wide study of CNV to be performed in AA samples, and the association finding in the MCHR2 gene region further underscores the potential role of pigmentation in AA development...

BACKGROUND: Eccrine duct dilation (EDD) and syringoma-like sweat duct proliferation have been described as reactive changes occurring in a variety of skin conditions. However, extensive evaluation of EDD in scalp biopsies performed for alopecia has not been performed. METHODS: We retrospectively examined 129 cases of cicatricial alopecia (lichen planopilaris, central centrifugal cicatricial alopecia, and discoid lupus erythematosus) and 130 cases of noncicatricial alopecias (androgenetic alopecia, telogen effluvium, and alopecia areata) for the presence of EDD...

Studies have identified increased prevalence of vitamin D deficiency in patients with alopecia areata (AA), an autoimmune disease characterized by hair loss, but none have prospectively examined vitamin D status and incident AA. In 55,929 women in the Nurses' Health Study (NHS), we prospectively evaluated the association between estimated vitamin D status, derived from a prediction model incorporating lifestyle determinants of serum vitamin D, and self-reported incident AA. We evaluated dietary, supplemental, and total vitamin D intake as additional exposures...

Phototherapy is a useful therapeutic method for various skin diseases due to its modulatory effect on the cutaneous immune system. Alopecia areata is a dermatosis characterized by partial or complete hair loss. Collapse of the immune privilege of the hair follicle, which induces noncicatricial alopecia, is an important factor in its etiology. Several forms of phototherapy are used in dermatology.

BACKGROUND: Hirschsprung's disease is one of the commonest causes of intestinal obstruction in neonates because of gut motility disorder. It is characterized as a complex genetic heterogenous disorder with variable inheritance. Hirschsprung's disease occurs as an isolated phenotype in majority (70 %) of cases. In other cases it may be associated with syndromes (such as Down's syndrome, Waardenburg syndrome, congenital central hypoventilation, or cartilage-hair hypoplasia) or with a spectrum of congenital anomalies involving neurological, cardiovascular, or urological systems or with sensorineural anomalies...

Alopecia areata (AA) over scalp is known to present in various shapes and extents of hair loss. Typically it presents as circumscribed patches of alopecia with underlying skin remaining normal. We describe a rare variant of AA presenting in linear band-like form. Only four cases of linear alopecia have been reported in medical literature till today, all four being diagnosed as lupus erythematosus profundus.

A 17-year-old girl presented with alopecia involving lateral margins of the scalp with primary amenorrhea. There was no history of parental consanguinity, and no other siblings were having similar complaints. Her secondary sexual characters were well developed with hypoplastic vagina. Histopathological findings from scalp biopsy showed features of alopecia areata. Ultrasonography of abdomen and pelvis revealed the absence of uterus and the right kidney. Follicle-stimulating hormone, luteinizing hormone, estradiol, testosterone, and thyroid function test was within normal limits...
