Treatment of HIV-associated eosinophilic pustular folliculitis with narrow-band UVB

Infantile Eosinophilic Pustular Folliculitis in a Child Aged 7 Years: A Case Report

Eosinophilic pustular folliculitis (EPF) is a rare, chronic, itchy, aseptic disease. Although most cases of infantile EPF (I-EPF) are detected in infants, we found that a 7-year-old child with I-EPF, who received treatment with oral azithromycin in combination with topical narrow bound Ultra Violet B light (NB-UVB) irradiation, with no recurrence at follow-up. Our experience with the successful treatment of this patient can provide a reference for more pediatric patients.

Review of narrowband ultraviolet B radiation in vitiligo

Vitiligo is a common, acquired pigmentary disorder of unknown etiology with great impact on patient’s appearance and quality of life. It presents a therapeutic challenge to many dermatologists. Photochemotherapy using psoralen and ultraviolet A (UVA) therapy, topical and oral immunosuppresants, as well as cosmetic camouflage are also commonly employed with varying clinical efficacy. Phototherapy is a popular treatment option, which includes both of the generalized ultraviolet B (UVB) therapies, broadband UVB and narrowband UVB (NB-UVB). It has been used favorably, both alone as well as in combination with other agents like topical calcineurin inhibitors, vitamin-D analogs. Combination therapies are useful and may provide quicker regimentation and treat vitiligo with an additive mechanism of action than UVB phototherapy. Advances in technology may lead to the continuing use of UVB phototherapy as a treatment for vitiligo through the development of sophisticated devices and delivery systems as well as innovative application methods. These will provide increased therapeutic options for all vitiligo patients, particularly those with refractory disease. In this article, I have reviewed the available data pertaining to efficacy and safety issues for NB-UVB as monotherapy, its comparison with psoralen plus UVA and other modes of phototherapy, combination regimens that have been tried and future prospects of NB-UVB in vitiligo.

Pruritic papular eruption in HIV: a case successfully treated with NB-UVB

Pruritic papular eruption (PPE) is a skin disease characterized by the eruption of itching papules on the extremities, face, and trunk; it is quite frequent in HIV-positive patients especially during the advanced immunosuppressive stage. PPE usually improves or heals when antiretroviral therapy restores the immune system function, but in some cases, it can take several months, and a symptomatic treatment for PPE is required. Systemic antihistamines, topical steroids, topical tacrolimus, itraconazole, pentoxyphilline, and ultraviolet B phototherapy have been proposed in cases of persisting PPE, but an elective treatment has not yet been found. We describe the case of a black patient affected by PPE, nonimproving with antiretroviral treatment, and resistant to topical steroids and oral antihistamines; a satisfactory and speedy result was achieved with narrow-band ultraviolet B phototherapy.

Neste artigo são abordadas as dermatoses neutrofílicas, complementando o artigo anterior (parte I). São apresentadas e comentadas as seguintes dermatoses: pustulose subcórnea de Sneddon-Wilkinson, dermatite crural pustulosa e atrófica, pustulose exantemática generalizada aguda, acroder matite contínua de Hallopeau, pustulose palmoplantar, acropustulose infantil, bacteride pustular de Andrews e foliculite pustulosa eosinofílica. Uma breve revisão das dermatoses neutrofílicas em pacientes pediátricos também é realizada.
