RESUMO
In this original research, we present the results in terms of effectiveness and safety of bimekizumab for hidradenitis suppurativa in real clinical practice. Results indicated significant improvement in all activity scores and patient-reported outcomes at week 16, including a notable decrease in mean IHS4 from 27.1 to 15.6 (p < 0.001), HS-PGA from 5.1 to 3.2 (p < 0.001), VAS pain from 8.3 to 4.7 (p < 0.001) and DLQI from 21.6 to 12.6 (p < 0.001). Bimekizumab, administered every 2 or 4 weeks, was well-tolerated with no discontinuations and no new safety concerns identified. These findings corroborate the drug's effectiveness and favourable safety profile observed in phase 3 clinical trials, supporting its use in real-world clinical practice for treating HS.
RESUMO
INTRODUCTION: The use of biological therapy is becoming increasingly common in patients with hidradenitis suppurativa (HS). Levels of serum TNF-alfa and IL17 support the role of an immune system dysregulation in the pathogenesis of HS. Brodalumab targets the receptor A of IL-17, thus having a promising role in the treatment of HS. MATERIAL AND METHODS: A multicenter retrospective observational open-label study was conducted in two tertiary hospitals. Adults with moderate to severe HS under treatment with brodalumab 210 mg at week 0, 1, 2 and then every 2 weeks were included and assessed at weeks 0 and 16 which was the median follow-up time. Demographic and disease-related variables as well as response parameters (HiSCR and IHS4) and safety data were recorded and analysed. RESULTS: A total of 16 patients (75% males) were included in our study. 50% of patients presented an inflammatory phenotype and mean BMI was 28.37. HiSCR was achieved in 50% of patients and mean IHS4 decreased from 24.13 to 16.81 (p = 0.002). No differences were found between those who achieved HiSCR and those who did not. Grade 2 adverse events were reported in three patients with no fatal outcomes and treatment discontinuation was advised in four patients. CONCLUSIONS: Brodalumab seems to be effective and safe in patients with moderate to severe HS, even in those that did not respond to adalimumab, which, at the moment, is the only widely approved biologic for this indication. Thus, it stands as an interesting option for the treatment of HS.

INTRODUCTION: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease. Biologic drugs have a key role in the long-term anti-inflammatory treatment of moderate to severe patients due to their immunomodulatory properties. The aim of this study is to evaluate the effectiveness and safety of secukinumab in patients with moderate to severe HS after 16 weeks of treatment, and to explore potential predictors of clinical response to the drug. METHODS: Multicenter observational retrospective study. Patients treated with secukinumab 300 mg every 2 or 4 weeks who had completed at least 16 weeks of follow-up from nine hospitals based in southern Spain (Andalusia) were included in this study. Treatment effectiveness was assessed using the Hidradenitis Suppurativa Clinical Response (HiSCR). Information about adverse events was collected, the therapeutic burden of the patients was calculated as the summation of systemic medical treatments and surgical interventions (excluding incision and drainage) experienced until the start of secukinumab treatment. RESULTS: Forty-seven patients with severe HS were included for analysis. At week 16, 48.9% (23/47) of patients achieved HiSCR. Adverse events were present in 6.4% (3/47) of the patients. The multivariate analysis showed that female sex and, to a lesser extent, lower body mass index (BMI) and a lower therapeutic burden were potentially associated with a higher probability of HiSCR achievement. CONCLUSIONS: Favorable short-term effectiveness and safety of secukinumab in the treatment of severe HS patients were observed. Female sex, lower BMI and a lower therapeutic burden may be associated with a higher probability of achieving HiSCR.

In recent years, tattoos have become more commonplace. However, this can result in various inflammatory processes, the management of which can be challenging in daily clinical practice. Tattoo-related inflammatory reactions can comprise different patterns, including acute and immediate reactions, foreign body granulomas, sarcoid granulomas, isomorphic lesions, allergic contact dermatitis and photosensitivity. We report three cases who were referred to the Dermatology Outpatient Clinic of the Hospital Universitario San Cecilio, Granada, Spain, in 2017 with various skin reactions in the red-ink areas of their tattoos. Screening was performed for infectious diseases like atypical mycobacterial infections and systemic processes such as sarcoidosis. A good therapeutic response was achieved in all cases. An adequate differential diagnosis is essential for the therapeutic management of this emerging health problem.

BACKGROUND: Folliculitis decalvans (FD) is a rare neutrophilic cicatricial alopecia that poses a therapeutic challenge. OBJECTIVES: To describe the therapeutic response in a large number of cases of FD with long-term follow-up and analyze potential prognostic factors associated with severity of form and with a better therapeutic response. METHODS: This multicenter prospective study included patients with FD who had a minimum of 5 years of follow-up. Severity was assessed by the maximum diameter of the cicatricial area. Therapeutic response was evaluated according to stabilization of the size of the cicatricial areas and the improvement in clinical symptoms. RESULTS: A total of 60 patients (37 men [61.7%] and 23 women [38.3%]) with a mean age of 40 years were included. Earlier age of onset (P = .01) was statistically associated with severity of form. Treatment with rifampicin and clindamycin, tetracyclines, and intralesional steroids was the most effective. No statistically significant prognostic factors predicting a better therapeutic response were found. LIMITATIONS: Because FD is a rare disease, the main limitation was the sample size. CONCLUSIONS: An earlier age of onset was associated with the severe form of the disease. The proposed specific therapeutic protocol can be a very useful tool in clinical dermatologic practice.

Mutations in ceramide biosynthesis pathways have been implicated in a few Mendelian disorders of keratinization, although ceramides are known to have key roles in several biological processes in skin and other tissues. Using whole-exome sequencing in four probands with undiagnosed skin hyperkeratosis/ichthyosis, we identified compound heterozygosity for mutations in KDSR, encoding an enzyme in the de novo synthesis pathway of ceramides. Two individuals had hyperkeratosis confined to palms, soles, and anogenital skin, whereas the other two had more severe, generalized harlequin ichthyosis-like skin. Thrombocytopenia was present in all patients. The mutations in KDSR were associated with reduced ceramide levels in skin and impaired platelet function. KDSR enzymatic activity was variably reduced in all patients, resulting in defective acylceramide synthesis. Mutations in KDSR have recently been reported in inherited recessive forms of progressive symmetric erythrokeratoderma, but our study shows that biallelic mutations in KDSR are implicated in an extended spectrum of disorders of keratinization in which thrombocytopenia is also part of the phenotype. Mutations in KDSR cause defective ceramide biosynthesis, underscoring the importance of ceramide and sphingosine synthesis pathways in skin and platelet biology.

A 70-year-old woman was referred to our dermatological unit by her general practitioner last summer, with a history of a two-month ulcerated purplish lesion on her left arm that spread centrifugally and that unsuccessfully treated with topical corticosteroids. The dermoscopic evaluation revealed an erythematous macula with central ulceration that showed the characteristic called "white starburst-like pattern" and some vascular structures (dotted vessels, polymorphous/ atypical vessels). The diagnosis of cutaneous leishmaniasis was made after histopathologic analysis and polymerase chain reaction essay.

Essential generalized telangiectasia as the result of postcapillary venule dilatation, is characterized by the sudden development of generalized telangiectasias, sometimes involving the conjunctiva. A few pediatric cases have been reported. The main condition in the differential diagnosis includes syndromes with telangiectasia such as hereditary hemorrhagic telangiectasia of Rendu-Osler, unilateral nevoid telangiectasia, and neonatal lupus erythematous. We present an 11-month-old boy that presented because of telangiectasia located on the face and neck. The telangiectasias appeared at two months of age and followed a progressive course. Nd-YAG laser therapy could be an interesting therapeutic approach in cosmetically compromised cases.
