  • Incidence of Alopecia Areata in lupus erythematosus.
    Archives of Dermatology, 1992
    Co-Authors: Victoria P. Werth, Miguel Sanchez, Wain L. White, Andrew G. Franks
    Abstract:

    • Background.— A small percentage of patients with Alopecia Areata have connective diseases such as systemic lupus erythematosus, discoid lupus erythematosus, rheumatoid arthritis, and scleroderma. Lupus erythematosus is associated with a number of different types of Alopecia, but the incidence of Alopecia Areata in lupus erythematosus has not been examined. Observations.— Of our cohort of 39 patients with lupus erythematosus, Alopecia Areata developed in 10% (four patients), in contrast to 0.42% of general dermatologic patients. Biopsy specimens of Alopecia Areata lesions in each of our patients showed continuous granular deposition of IgG at the dermoepidermal junction, a finding usually found in only a minority of Alopecia Areata cases. Intralesional injections of corticosteroids were effective treatment. Conclusions.— The incidence of Alopecia Areata in patients with lupus erythematosus is increased. Recognition of this form of Alopecia allows for specific therapy with intralesional corticosteroids. ( Arch Dermatol. 1992;128:368-371)

  • Childhood Alopecia Areata-Data from the National Alopecia Areata Registry.
    Pediatric Dermatology, 2018
    Co-Authors: Iris Wohlmuth-wieser, Joyce S. Osei, Maria K Hordinsky, David A Norris, Vera H. Price, Angela M Christiano, Madeleine Duvic
    Abstract:

    BACKGROUND/OBJECTIVES: Alopecia Areata may occur at any age and is the third-most-common dermatosis in children. The objective of this study was to investigate the clinical and epidemiologic features of children and adolescents with Alopecia Areata based on the data of the National Alopecia Areata registry on children and adolescents. METHODS: Two thousand two hundred eighteen children and adolescents with Alopecia Areata self-enrolled in the National Alopecia Areata Registry and completed a web-based, self-administered, short-intake screening questionnaire (first tier). In the second tier, 643 patients participated in a clinical examination and completed a long-form questionnaire. RESULTS: Mean age of onset was 5.9 ± 4.1 years. With a female to male ratio of 1.5:1, Alopecia Areata was more prevalent in girls, but boys were significantly more likely to have a severe type (P = .009). One-fourth of all children had a positive family history, with 8% having more than three affected relatives. The disease most commonly associated with Alopecia Areata was atopic dermatitis (32.7%). CONCLUSION: Childhood Alopecia Areata is more prevalent in girls than in boys, but boys have more extensive Alopecia Areata. Despite the low prevalence, congenital Alopecia Areata is an important differential diagnosis for neonatal hair loss. Alopecia Areata runs in families, suggesting an underlying genetic background. One-quarter of the children reported at least one affected first-degree relative; 8% had more than three affected relatives.

  • Overview of Alopecia Areata
    Journal of Investigative Dermatology Symposium Proceedings, 2013
    Co-Authors: Maria K Hordinsky
    Abstract:

    Alopecia Areata is a complex genetic, immune-mediated disease that targets anagen hair follicles. The disease affects children and adults and is characterized by round or oval patches of hair loss, loss of all scalp hair (Alopecia totalis), body hair (Alopecia universalis), or ophiasis pattern hair loss. Patients may also present with patchy loss in multiple hair-bearing areas. Commonly associated diseases include asthma, allergic rhinitis, atopic dermatitis, thyroid disease, and automimmune diseases, such as thyroiditis and vitiligo. Nail abnormalities may precede, follow, or occur concurrently with hair loss activity. Alopecia Areata has no known age, race, or ethnic preponderance and in contrast to other autoimmune diseases such as thyroiditis or lupus, the hair follicle does not usually sustain permanent injury and maintains its potential to regrow hair. It is estimated that Alopecia Areata affects between six and seven million individuals in the United States. Genes, the immune and nervous systems have all been implicated in the pathogenesis of Alopecia Areata. Although many treatments are available, there is still no cure. Bolstered by new scientific and translational opportunities from recently published genome-wide association studies, an ambitious treatment development program has recently been initiated by the National Alopecia Areata Foundation.

  • Alopecia Areata investigational assessment guidelines part ii
    Journal of The American Academy of Dermatology, 2004
    Co-Authors: Elise A Olsen, Jerry Shapiro, Janet L Roberts, Doug Canfield, Lloyd E. King, Maria K Hordinsky, Madeleine Duvic, Vera H. Price, Anthony J. Mcmichael, Valerie Randall
    Abstract:

    Alopecia Areata is an immunologically mediated disease characterized by extreme variability not only in the time of initial onset of hair loss but in the duration, extent and pattern of hair loss during any given episode of active loss. These variables, as well as the unpredictable nature of spontaneous regrowth and lack of a uniform response to various therapies, has made clinical trials in Alopecia Areata difficult to plan and implement. In fact, there are currently no drugs FDA-approved specifically for the indication of Alopecia Areata. To help facilitate well-controlled clinical trials for Alopecia Areata, this National Alopecia Areata Foundation (NAAF) sponsored subgroup of investigators/clinicians experienced in clinical trials and/or in the clinical care of patients with Alopecia Areata has outlined some general principles and potential endpoints for clinical studies in Alopecia Areata.Theseguidelines buildontheAlopeciaAreata

  • Autoimmunity: Alopecia Areata
    The journal of investigative dermatology. Symposium proceedings, 2004
    Co-Authors: Maria K Hordinsky, Marna E. Ericson
    Abstract:

    Strong direct and indirect evidence supports an autoimmune etiology for Alopecia Areata. T lymphocytes that have been shown to be oligoclonal and autoreactive are predominantly present in the peribulbar inflammatory infiltrate. Alopecia Areata frequently occurs in association with other autoimmune diseases, such as thyroiditis and vitiligo, and autoantibodies to follicular components have been detected. Finally, the use of immune modulating drugs, including corticosteroids and contact sensitizers such as dyphencyprone, can be beneficial in the management of this disease. Recent studies have demonstrated that Alopecia Areata scalp skin grafted onto nude mice with severe combined immunodeficiency grow hair and that infiltrating lymphocytes in the graft are lost. It is now also possible to induce Alopecia Areata in human scalp explants on these mice by injecting T lymphocytes with scalp homogenate. Neuropeptides produced by cutaneous nerves are known to modify immune reactivity and, in all likelihood, affect the Alopecia Areata process. Future studies may show that modulation of neuropeptide expression is associated with hair regrowth. Likewise, testing the efficacy of the newly developed immunomodulatory agents in patients with Alopecia Areata may lead to the introduction of novel therapies for this immune-mediated disease of the hair follicle.

  • Alopecia Areata in infants and newborns
    Pediatric dermatology, 2002
    Co-Authors: Julie Anne Crowder, Ilona J. Frieden, Vera H. Price
    Abstract:

    Alopecia Areata is a common cause of nonscarring hair loss in children and adults. In newborns and very young infants, however, it is thought to be extremely rare. In this article we describe five cases of Alopecia Areata in patients less than 6 months of age and briefly discuss the pertinent differential diagnosis of infants and newborns with both patchy and complete hair loss. We propose that Alopecia Areata may be more common in this age group than the literature suggests.

  • Sulfasalazine for Alopecia Areata.
    Journal of the American Academy of Dermatology, 2002
    Co-Authors: Charles N. Ellis, Margaret F. Brown, John J. Voorhees
    Abstract:

    Abstract Sulfasalazine is used as a therapy for various autoimmune conditions, including psoriasis; its effectiveness is presumed to be the result of its immunomodulatory effects. We have treated patients with severe Alopecia Areata with sulfasalazine as part of our dermatology practice and have noticed cosmetically acceptable regrowth in 23% of patients in whom a response could be determined. In view of its good safety profile, sulfasalazine may be considered for systemic treatment of severe Alopecia Areata. (J Am Acad Dermatol 2002;46:541-4.)
