Consensus statement from the AEDV Psoriasis Working Group (SWG) and Pediatric Working group (PWG) on the management of pediatric psoriasis. / Documento de consenso del Grupo Español de Psoriasis (GPS) y del grupo Español de Dermatología Pediátrica (GEDP) de la AEDV sobre el manejo de la psoriasis pediátrica.

Justification and objectives: The Spanish Academy of Dermatology and Venereology (AEDV) Psoriasis and Pediatric Working Groups (PSW and PWG) have developed a set of recommendations for the management of pediatric psoriasis based on the best available evidence and experts' opinion. Methodology: The methodology of nominal groups was followed, with help from a scoping review. A coordinator was designated, and a group of experts was selected based on their experience and knowledge on the management of psoriasis. The coordinator defined both the objectives and the key points of the document. Then, with help from a documentalist, a systematic literature review was conducted across Medline, Embase and Cochrane Library until May 2023. Systematic literature reviews, meta-analyses, and observational studies were included. National and international clinical practice guidelines and consensus documents were reviewed. With this information, the coordinator proposed preliminary recommendations that were discussed and modified in a nominal group meeting with all experts. After several review processes, which included an external review, the final document was generated. Results: Practical recommendations on the evaluation and management of patients with pediatric psoriasis are presented in association with other AEDV documents. The evaluation of the pediatric patient, the definition of the therapeutic objectives, the criteria for indication and selection of treatment are addressed. Practical issues such as therapeutic failure, response maintenance, comorbidity and risk management are also included.

Anetoderma after disseminated Mpox.

Anetoderma or macular atrophy is a rare skin condition of unclear pathogenesis, often associated with autoimmune diseases and skin damage from various infections. Human immunodeficiency virus (HIV), syphilis, and poxviruses have been implicated in the development of anetoderma. A 37-year-old male patient with HIV and recent unprotected sexual encounters presented with more than 400 skin lesions, consistent with Mpox. Symptomatic treatment for Mpox resulted in acute symptom resolution. However, 8 months later he developed papular anetoderma lesions in areas previously affected by Mpox. Biopsy confirmed the loss of elastic fibers in the affected skin areas, leading to the diagnosis of Mpox-induced anetoderma. This report presents a unique case of anetoderma following Mpox in an HIV-positive patient.

Efficacy of Omalizumab for the treatment of Bullous Pemphigoid. Spanish multicenter real-world experience.

BACKGROUND: Bullous Pemphigoid (BP) is the most common autoimmune blistering disease. Most patients are elderly and associate multiple comorbidities. Topical and systemic corticosteroids are considered as the first-line treatment for BP and immunosuppressors are used as steroid-sparing treatments but both have side effects and contraindications which are even more common in this elderly population. New treatments targeting interleukins and receptors related to BP pathogenesis have been proposed to decrease this side effects while achieving equal or better effectiveness response rates.Omalizumab is a monoclonal antibody that targets IgE that has been proposed for the treatment of BP due to the evidence that IgE autoantibodies play an essential role in BP pathogenesis. OBJECTIVES AND METHODOLOGY: To assess the efficacy and security of Omalizumab for the treatment of BP, we carried out a multicenter, retrospective, observational study including patients diagnosed of BP who received omalizumab for at least 3 months from 15 tertiary hospitals in Spain. IgE levels prior to treatment was measured and we evaluate the possible correlation with clinical response. We excluded patients treated with Omalizumab for less than 3 months as we consider this duration is insufficient for a comprehensive assessment of its efficacy. To evaluate the effectiveness of the treatment we used the percentage of BSA improvement. RESULTS: We included 36 patients. The vast majority associate multiple comorbidities and all patients had used other systemic therapies apart from corticoids before Omalizumab.83% experienced some kind of treatment response and 42% of all patient treated achieved complete response.We did not find any correlation between higher levels and a better response (p=0,1791).All patients tolerated Omalizumab without reported side-effects. CONCLUSIONS: Omalizumab is a good therapeutic alternative for BP as it obtained clinical response in most patients and nearly half of the cases achieving complete response. It showed no side effects which is crucial in elderly patients suffering from BP.

Ecology and resistance to UV light and antibiotics of microbial communities on UV cabins in the dermatology service of a Spanish hospital.

Microorganisms colonize all possible ecological habitats, including those subjected to harsh stressors such as UV radiation. Hospitals, in particular the UV cabins used in phototherapy units, constitute an environment in which microbes are intermittently subjected to UV irradiation. This selective pressure, in addition to the frequent use of antibiotics by patients, may represent a threat in the context of the increasing problem of antimicrobial resistance. In this work, a collection of microorganisms has been established in order to study the microbiota associated to the inner and outer surfaces of UV cabins and to assess their resistance to UV light and the antibiotics frequently used in the Dermatology Service of a Spanish hospital. Our results show that UV cabins harbor a relatively diverse biocenosis dominated by typically UV-resistant microorganisms commonly found in sun-irradiated environments, such as Kocuria, Micrococcus or Deinococcus spp., but also clinically relevant taxa, such as Staphylococcus or Pseudomonas spp. The UV-radiation assays revealed that, although some isolates displayed some resistance, UV is not a major factor shaping the biocenosis living on the cabins, since a similar pool of resistant microorganisms was identified on the external surface of the cabins. Interestingly, some Staphylococcus spp. displayed resistance to one or more antibiotics, although the hospital reported no cases of antibiotic-resistance infections of the patients using the cabins. Finally, no association between UV and antibiotic resistances was found.

Monkeypox whitlow: a novel presentation.

Monkeypox is a rare zoonotic disease with a progressive increase in cases among men who have sex with men (MSM) worldwide in recent months. New complications of this infection have been described. The aim of the study was to describe this new pattern of presentation of monkeypox at the level of the finger. We present the cases of three patients with monkeypox whitlow, a new clinical presentation of monkeypox. The patients were three MSM with ages ranging from 32 to 49 years. All three had involvement of the third finger of the dominant hand as well as skin lesions at other sites. Two of the three patients had severe inflammation in the digit and proximal arm and were treated with systemic corticosteroids with significant improvement. In two of the three cases we observed onychodystrophy as a complication. All patients reported sexual intercourse with previous digital-anal penetration with the affected finger, which may be the mode of transmission. Distinguishing features that need to be considered are discussed.

Clinical and Demographic Features of 49 Patients With Human Monkeypox Virus-Confirmed Infection in a Tertiary Care Center in Valencia, Spain: A Descriptive Study.

Monkeypox is a previously rare viral zoonosis affecting predominantly the African continent. Since May 2022, an increasing number of cases with no known epidemiologic link to Africa have been reported for the first time in the rest of the world. We described the epidemiologic and clinical characteristics of all patients attended at our center until August 9 with a confirmed diagnosis of monkeypox. Forty-nine patients were included. The mean age was 37.6 years. Ninety-eight percent of patients were male, 96% were men who have sex with men, and 4% were heterosexual. Thirty-one percent of patients had a history of human immunodeficiency virus infection. Ninety-six percent of patients declared a unprotected sexual relationship before the onset of symptoms, and 41% had a history of recent travel. Ninety-eight percent of patients presented with cutaneous involvement affecting the genital (59%), perianal (41%), and perioral (35%) regions. Systemic symptoms were present in 80% of the patients and included lymphadenopathies (71%), asthenia (65%), fever (65%), headache (37%), arthromyalgias (45%), pharyngitis (35%), proctitis (29%), and dysuria (6%). Coinfection by other sexually transmitted infections was detected in 20% of patients. The sensitivity values of polymerase chain reaction test for monkeypox in urethral, anal, and oropharyngeal exudates analyzed were 88%, 79%, and 68%, respectively. Complications included a myopericarditis that represented the only hospitalized patient, edema (8%) and bacterial superinfection (4%). No deaths were reported. The findings of this case series support the sexual contact as the main route of transmission of the disease and highlight some atypical clinical presentations not described in endemic cases.

Brentuximab vedotin in the treatment of cutaneous T-cell lymphomas: Data from the Spanish Primary Cutaneous Lymphoma Registry.

BACKGROUND: Brentuximab vedotin (BV) has been approved for CD30-expressing cutaneous T-cell lymphoma (CTCL) after at least one previous systemic treatment. However, real clinical practice is still limited. OBJECTIVES: To evaluate the response and tolerance of BV in a cohort of patients with CTCL. METHODS: We analysed CTCL patients treated with BV from the Spanish Primary Cutaneous Lymphoma Registry (RELCP). RESULTS: Sixty-seven patients were included. There were 26 females and the mean age at diagnosis was 59 years. Forty-eight were mycosis fungoides (MF), 7 Sézary syndrome (SS) and 12 CD30+ lymphoproliferative disorders (CD30 LPD). Mean follow-up was 18 months. Thirty patients (45%) showed at least 10% of CD30+ cells among the total lymphocytic infiltrate. The median number of BV infusions received was 7. The overall response rate (ORR) was 67% (63% in MF, 71% in SS and 84% in CD30 LPD). Ten of 14 patients with folliculotropic MF (FMF) achieved complete or partial response (ORR 71%). The median time to response was 2.8 months. During follow-up, 36 cases (54%) experienced cutaneous relapse or progression. The median progression free survival (PFS) was 10.3 months. The most frequent adverse event was peripheral neuropathy (PN) (57%), in most patients (85%), grades 1 or 2. CONCLUSIONS: These results confirm the efficacy and safety of BV in patients with advanced-stage MF, and CD30 LPD. In addition, patients with FMF and SS also showed a favourable response. Our data suggest that BV retreatment is effective in a proportion of cases.
