Moderate to Severe Psoriasis in Pediatric and Young Patients: The BIOBADADERM Registry Experience. / Psoriasis moderada-grave en pacientes pediátricos y jóvenes: experiencia en el registro BIOBADADERM.

Childhood-onset psoriasis generally follows an indolent course but patients with moderate or severe disease may require systemic treatment. The aim of this study was to determine the relative proportion of children and young people aged up to 21 years with moderate to severe psoriasis in the BIOBADADERM registry and to analyze the characteristics of these patients, treatments used, and adverse events. Of the 3946 patients in the registry, 24 were aged 21 years or younger. They had mean age of 16.1 years on starting treatment. When the registry was started, they had a Psoriasis Area and Severity Index of 9.4 and 67% were being treated with a conventional systemic drug. Treatment was discontinued in 14 patients (58%) due to adverse events or a loss or lack of effectiveness. In conclusion, the BIOBADADERM registry shows that young people account for a small proportion of psoriasis patients receiving systemic treatment, and they are more likely to be treated using conventional systemic drugs.

[Surgical treatment of relapsing keloid of the pinna by fillet flap]. / Tratamiento quirúrgico del queloide recidivante de pabellón auricular mediante <>.

BACKGROUND AND OBJECTIVES: Keloid scars occur when, compared to normal healing, there is excessive formation of collagen after skin wounds or burns. Different treatments have been tried, though no particular one has been shown to be superior. The objective of this study was to assess the usefulness of the surgical technique originally described as keloid fillet flap in the management of relapsing keloids of the pinna. MATERIAL AND METHODS: The study included 10 patients (8 men, 9 white and 1 black) with a keloid on the retroauricular region or earlobe of more than 1 year duration, who had undergone previous treatment (surgery and topical or injected corticosteroids) without a good outcome or with relapse, and who had not received any treatment in the previous 6 months. RESULTS: Five patients were treated with a fillet flap procedure only, while the other 5, in addition to the procedure, also applied 5% imiquimod cream 5 times a week for 1 to 3 months. In 4 patients, no relapse was observed after the intervention. Two patients had partial flap necrosis, with subsequent partial relapse in one of these. Eighty percent reported the outcome of the procedure as good or excellent. CONCLUSION: We achieved a response rate of 40% in the treatment of relapsing keloid of the pinna by a fillet flap procedure. This may be an alternative within the therapeutic arsenal for the treatment of relapsing keloid of the pinna, given that it does not require extensive resources and the skills needed to perform the procedure can be quickly acquired.

Changing Trends in Drug Prescription and Causes of Treatment Discontinuation of First Biologic Over Ten Years in Psoriasis in the Spanish Biobadaderm Registry. / Cambios en las tendencias de la prescripción y causas de la interrupción en los tratamientos biológicos indicados en la psoriasis durante los primeros 10 años. Datos obtenidos del registro español Biobadaderm.

BACKGROUND AND OBJECTIVES: Current psoriasis guidelines do not usually include recommendations about first line classical or biologic treatment. The objectives of this study were: to describe shifts in the prescription of the first biological treatment, and to compare treatment withdrawal and rates of adverse events over ten years. MATERIAL AND METHODS: Biobadaderm registry was analyzed to describe: first biological prescription in bio-naïve patients, adverse events rate and reasons for drug withdrawal comparing three periods of time (2008-2010, 2011-2014, 2015-2018). RESULTS: Anti-TNF drugs were the most prescribed biological drug from 2008 to 2010. Ustekinumab has become the most prescribed first biologic since 2014. The main reasons for drug discontinuation were adverse events, lack of efficacy and remission. In each period any treatment was less likely to be discontinued due to any of these three reasons comparing to the previous period. CONCLUSIONS: The present study identifies trends in prescription of the first biological antipsoriatic drug in clinical practice from 2008 to 2018. It suggests that we have become more comfortable with the safety profile and more exigent with the efficacy of the drugs.

Redefining the therapeutic objective in psoriatic patients candidates for biological therapy.

The advances in psoriasis management currently allow achieving a good control of the disease. In particular, with the latest developed molecules, available evidence suggests that it is possible to pose an ambitious therapeutic goal, such as a Dermatology Life Quality Index 0/1, a Physician Global Assessment 0/1, or a Psoriasis Area and Severity Index 90/100 response. However, patients often fail to achieve the complete clearance of their cutaneous lesions or the improvement of disease factors that impair their quality of life. To optimize the treatment of psoriasis, it is not enough to define precisely the therapeutic objective, but also to adapt the therapeutic strategy to make the necessary modifications in case of not achieving it at the time point (at the end of the induction phase, or every 3-6 months) to be agreed with the patient (the so-called treat-to-target approach). In the present report, based on the Delphi methodology, 11 dermatologists from the Spanish Psoriasis Group addressed key issues that could be involved in the achievement and maintenance of the therapeutic goals of patients with moderate to severe psoriasis. The document provides 27 consensus statements intended to support clinical decision-making by healthcare professionals for patients who might be candidates to receive biologic therapy.

[Experience in the treatment of cutaneous in-transit melanoma metastases and satellitosis with intralesional interleukin-2]. / Experiencia en el tratamiento de satelitosis y metástasis cutáneas en tránsito de melanoma con interleucina 2 intralesional.

INTRODUCTION: Although metastatic melanoma has a poor prognosis, cutaneous metastases represent a special case given their ready accessibility, making it possible for dermatologists to apply local treatment. We report our experience with intralesional treatment with interleukin (IL) 2 in 7 patients with cutaneous metastases from malignant melanoma. MATERIAL AND METHODS: A total of 244 lesions in 7 patients with satellitosis and/or cutaneous metastases from malignant melanoma were treated with intralesional IL-2 twice a week. The maximum dose in each patient ranged from 3 to 18 million units per session, according to the number and size of lesions. RESULTS: Complete or partial remission was achieved in almost all lesions (95.9 % and 3.7 %, respectively).Only 1 lesion (0.4 %) -the largest and located subcutaneously- did not respond to intralesional treatment and required alcoholization and subsequent surgical removal to achieve cure. All partial responses occurred in subcutaneous lesions larger than 2 cm. Treatment was well tolerated with only a few mild side effects (grade 1-2). CONCLUSIONS: IL-2 may be an effective and well-tolerated treatment option in patients with satellitosis and cutaneous metastases from melanoma. Lesions smaller than 2 cm and located in the epidermis or superficial dermis respond better than those larger than 2 cm or located in the subcutaneous cellular tissue. More studies are necessary to establish appropriate doses and regimens.
