ABSTRACT

FUNDAMENTOS: Muitos pacientes relatam melhora da acne com a exposição à luz solar, e vários estudos demonstram que a luz azul é efetiva no tratamento da acne. OBJETIVOS: Verificar a segurança e a eficácia da luz azul (espectro eletromagnético de 407 a 420 nm) no tratamento da acne inflamatória graus II e III, comparada à terapêutica tópica com peróxido de benzoíla a 5 por cento. MÉTODOS: O estudo avaliou 60 pacientes em cinco visitas: uma de seleção, uma com 7, 14 e 28 dias de tratamento e uma última de seguimento, 14 dias após o término do tratamento. Trinta foram randomizados para luz azul (oito sessões, duas vezes por semana), e outros 30, para peróxido de benzoíla a 5 por cento, duas vezes ao dia, diariamente. A avaliação foi por meio da contagem das lesões e fotografias. RESULTADOS: A redução no número médio de lesões foi semelhante com os dois tratamentos, independente do tipo de lesão (p 0,05), porém o tratamento com a luz azul apresentou menos efeitos colaterais. CONCLUSÕES: A luz azul foi um tratamento tão eficaz quanto o peróxido de benzoíla a 5 por cento para o tratamento da acne graus II e III, mas com menos efeitos adversos.


BACKGROUND: Many acne patients improve after exposure to sunlight and there are many reports about the efficacy of blue light phototherapy on acne lesions. OBJECTIVES - The purpose of this study was to evaluate efficacy and safety of blue light treatment versus topical benzoyl peroxide 5 percent formulation in patients with acne grades II and III. METHODS - Sixty volunteers with facial acne were included and evaluated in 5 visits: the first one for screening, another 3 held on days 7, 14 and 28 of treatment, and the last one after 14 days of the end of treatment. Thirty of them were irradiated with Blue Light (8 times, twice a week) and the other thirty were treated with topical Benzoyl Peroxide 5 percent formulation, auto-applied twice a day, every day. We assessed the severity of acne by counting the lesions and analyzing the photographs. RESULTS - The improvement achieved by the blue light was the same as the one with benzoyl peroxide, regardless of the type of lesion (p 0.05). Otherwise, the side effects were less frequent in the group treated with blue light. CONCLUSIONS - Blue light irradiation was as effective as Benzoyl Peroxide in acne treatment grades II and III but there were fewer side effects.

ABSTRACT

La acné es una enfermedad muy frecuente que aparece alrededor de la pubertad y se caracteriza por su polimorfismo lesional y su cronicidad. Se la divide en grados de severidad y según los mismos se determina la terapéutica adecuada. Tiene un alto impacto psicosocial en quienes la padecen por lo cual es muy importante el vínculo que se establece entre el paciente y su médico, lo cual redundará en una buena aceptación del tratamiento y una mejor respuesta por parte del paciente. En los últimos años se ha avanzado en el conocimiento de su etiopatogenia, lo cual permitió un entendimiento más profundo de la enfermedad. La tendencia actual es la de combinar diferentes drogas que tengan influencia sobre diferentes etiopatogénicos de la acné. Se ha comprobado que de este modo la respuesta es más rápida y el tratamiento menos tóxico

ABSTRACT

A clinical trial using Airol cream (retinoic acid cream 0.05%), Panoxyl-5 and Panoxyl-10 (benzoyl-peroxide alcoholic gel 5% & 10%) in combination and alone as topical applications for 10 weeks was carried out on 150 ambulatory patients with acne vulgaris. The results based on efficacy, drug tolerance and treatment duration show that the combined use of Panoxyl and Airol is superior to the use of either drug alone and that the combination of Airol cream (0.05%) in the morning and Panoxyl gel (5%) before retiring was the most satisfactory.
