Diagnostic and therapeutic guidelines for plaque psoriasis - Brazilian Society of Dermatology.

Psoriasis is a chronic inflammatory disease that affects 1.3% of the Brazilian population. The most common clinical manifestations are erythematous, scaling lesions that affect both genders and can occur on any anatomical site, preferentially involving the knees, elbows, scalp and genitals. Besides the impact on the quality of life, the systemic nature of the disease makes psoriasis an independent risk factor for cardiovascular disease, especially in young patients with severe disease. By an initiative of the Brazilian Society of Dermatology, dermatologists with renowned clinical experience in the management of psoriasis were invited to form a work group that, in a partnership with the Brazilian Medical Association, dedicated themselves to create the Plaque Psoriasis Diagnostic and Treatment Guidelines. The relevant issues for the diagnosis (evaluation of severity and comorbidities) and treatment of plaque psoriasis were defined. The issues generated a search strategy in the Medline-PubMed database up to July 2018. Subsequently, the answers to the questions of the recommendations were devised, and each reference selected presented the respective level of recommendation and strength of scientific evidence. The final recommendations for making up the final text were worded by the coordinators.

Abstract: Psoriasis is a chronic inflammatory disease that affects 1.3% of the Brazilian population. The most common clinical manifestations are erythematous, scaling lesions that affect both genders and can occur on any anatomical site, preferentially involving the knees, elbows, scalp and genitals. Besides the impact on the quality of life, the systemic nature of the disease makes psoriasis an independent risk factor for cardiovascular disease, especially in young patients with severe disease. By an initiative of the Brazilian Society of Dermatology, dermatologists with renowned clinical experience in the management of psoriasis were invited to form a work group that, in a partnership with the Brazilian Medical Association, dedicated themselves to create the Plaque Psoriasis Diagnostic and Treatment Guidelines. The relevant issues for the diagnosis (evaluation of severity and comorbidities) and treatment of plaque psoriasis were defined.

Treatment of psoriasis. Part 1. Topical therapy and phototherapy

New developments in the topical therapy and phototherapy of psoriasis have greatly improved our ability to safely and effectively treat this debilitating disease. Topical corticosteroids remain the most commonly prescribed agents for psoriasis, but they are frequently prescribed with other agents. Investigations of corticosteroids claiming an improved benefit/risk ratio have yielded promising results, but more work is needed. Use of anthralin and tar has declined with the availability of the noncorticosteroids calcipotriene and tazarotene. Other experimental topical therapies are in various stages of development. Broadband ultraviolet B (UVB) remains the most commonly used phototherapy light source, but many patients are being treated with a new form of ultraviolet light, narrowband UVB. Although PUVA remains one of the most effective psoriasis treatments, its use is declining because of its association with cutaneous malignancies. New radiation sources such as lasers have been added to our armamentarium of available therapies and even newer light source-based treatments are being examined. LEARNING OBJECTIVE: At the conclusion of this learning activity, participants should be familiar with the varying topical treatments for psoriasis as well as the different modalities of phototherapy. Participants should also have a better understanding of side effects associated with each treatment, which should help in determining options for therapy.

Tratamiento de la alopecia areata / Treatment of the alopecia areata

En una patología como la alopecía areata, la que se presenta de distintas formas clínicas, con asociaciones variadas, donde las remiciones son posibles y los tratamientos disponibles no son 100 por ciento eficaces, es dificil evaluar la terapéutica más adecuada. lLos tratamientos disponibles pueden dividirse en tópicos y sistémicos. Los corticoides ocupan un lugar importante en el arsenal terapéutico, en especial los tópicos o en inyecciones intralesionales. Otrs productos se usan con resultados varioables como la inminoterapia tópica, en especial con el minoxidil, la difenciprona y la antralina. La medicación sistïrmica se reserva para casos severos (corticosteroides,ciclosporina A, etc). La mayoría actuarían alterando la respuesta inmune y en otros en controvertida. Consideramos a la afección dentro de su marco general, más que etético, pero sin descuidar la integridad del individuo y hacia esto debemos apuntar en nuestra estrategia de tratamiento. La relación paciente-médico es fundamental para manejar esta enfermedad en la que aún no tenemos una medicación curativa.

Aspectos clínicos de la alopecia areata: tratamiento tópico comparativo entre antralina y betametasona / Clinical aspects of the alopesia areata: comparative topical treatment between anthralin and betamethasane

En forma prospectiva se estudiaron los aspectos clínicos de 53 pacientes con alopecia areata. Las asociaciones más frecuentes fueron el estrés emocional agudo, los antecedentes familiares y los antecedentes personales de la enfermedad. Se realizó un estudio terapéutico comparativo entre antralina y betametasona tópica, resultando superior la antralina en forma estadísticamente significativa

Estudo clínico com ditranol (antralina) em altas concentraçöes na terapia de contato curto na psoríase / Multicenter study evaluating short contact therapy for psoriasis with dithranol (anthralin) in high concentrations

Foi realizado um estudo multicêntrico aberto, näo comparativo em quatro centros dermatológicos universitários, com a participaçäo de 95 pacientes, utilizando-se pomadas contendo 1, 2 e 3% de ditranol (antralina ou cignolina) para avaliaçäo da terapia de contato curto na psoríase. A pomada foi aplicada uma vez ao dia, por 10 a 30 minutos no máximo, sendo as avaliaçöes clínicas realizadas no pré-tratamento, primeira, terceira, oitava e décima segunda semanas de tratamento (se necessário). Dos 95 pacientes tratados, 60 (63,2%) eram do sexo masculino e 35 (36,8%) do sexo feminino, com idades variando entre 18 e 79 anos (média = 40), com quadro clínico característico de psoríase vulgar, apresentando lesöes localizadas ou disseminadas. Ao final do estudo foram avaliados 69 pacientes dos quais 57(82,6%) apresentaram resultados excelentes ou bons e em quatro (5,8%) os resultados foram regulares. Em seis pacientes näo houve resposta terapêutica satisfatória e em dois ocorreram reaçöes irritantes näo toleradas. Dos 26 pacientes restantes, dois abandonaram o tratamento logo no início por motivos particulares e 24 näo compareceram à última ou duas últimas avaliaçöes. Destes, 14 pacientes apresentavam resultados bons e oito regulares quando examinados pela última vez. A tolerância ao ditranol em altas concentraçöes foi satisfatória já que somente dois pacientes foram retirados do estudo por intolerância à açäo irritativa tópica

UVABA therapy for psoriasis. Efficacy with shortened treatment times with the combined use of coal tar, anthralin, and metal halide ultraviolet machines.

Rapid clearing of psoriasis in a psoriasis treatment center setting has been obtained with a combination of short-contact coal tar, phototherapy from high-pressure metal halide lamps (consisting of UVA and UVB), and short-contact high-potency anthralin therapy. These intensive 1 1/2- to 2-hour treatment sessions done three or four times weekly were as efficacious as reported responses to PUVA therapy or conventional psoriasis day care therapy. The treatment schedule allows minimal time away from work, decreased hours per week in contact with crude coal tar, shortened UV treatment times, decreased cost, and a low risk of side effects. It is suggested that the use of UVA and UVB combined with anthralin (UVABA) is effective for many patients with moderate to severe psoriasis.

Antralina: visäo atual de uma droga antiga / Antralin: a present view of an old drug

Os autores apresentam uma revisäo ampla dos aspectos históricos do emprego da antralina, suas características químicas, formulaçöes e mecanismos de açäo farmacológicos, destacando seus efeitos colaterais e toxicidade. Em uma segunda parte, säo analisadas as indicaçöes terapêuticas, especialmente na psoríase e as utilizaçöes atuais em outras patologias

Terapia con antralina y dimetilsulfóxido en pacientes hospitalizados y ambulatorios con psoriasis / Treatment of psoriasis with Anthralin and dimethyl sulfoxide in ambulatory and hospitalized patients

Se evalúa la eficacia de la Antralina y Dimetilsulfóxido en 2 grupos de pacientes portadores de psoriasis: 55 enfermos ambulatorios y 19 hospitalizados. La concentración de Antralina varió enntre 0,025% a 1% asociado a Dimetilsulfóxido (DMSO) en concentraciones variables (0.025-1%) según tipo de psoriasis. El DMSO es un potente antiinflamatorio que se utilizó con el fin de lograr una buena penetración en la placa hiperqueratósica de la psoriasis y disminuir el efecto irritativo-inflamatorio de la Antralina. Se observó remisión de las placas de psoriasis en el 84,2% del grupo de pacientes hospitalizados y en el 42,1% de los enfermos ambulatorios. Esta diferencia resultó significativa (p<0.005). Se destaca la buena respuesta de la psoriasis de placa gruesa y en psoriasis inversa. Como efectos colaterales se constató pigmentación del área afectada en un elevado porcentaje, así como prurito y eritema. Se concluye que la asociación de Antralina y DMSO parece ser una solución adecuada para aquellos casos de psoriasis que no respondan a tratamientos habituales y que tiene mayor rendimento si los pacientes se hospitalizan
