Dupilumab induced ocular surface disease: A prospective case series.

Purpose: To identify the incidence, risk factors, demographics, and clinical profile of dupilumab-induced ocular surface disease (DIOSD) in patients with atopic dermatitis (AD), propose a standardised treatment protocol (STP) and evaluate the response.

Methods: Prospective case series of AD patients treated in the Dermatology Department, Royal Victoria Infirmary, Newcastle upon Tyne, UK developing ocular symptoms after commencing Dupilumab between September 2018 and February 2020. A standard history and examination protocol were used including subjective symptom severity grading and Ocular Surface Disease Index (OSDI) questionnaire on each visit.

Cutaneous manifestations of acute kidney injury.

Acute kidney injury (AKI) is a common medical problem with a multitude of aetiologies. Prompt diagnosis and management is key in the prevention of complications. Cutaneous signs can often give diagnostic clues of underlying systemic diseases causing AKI.

Exploring the perspectives of dermatology undergraduates with an escape room game.

Background: A UK dermatology curricula review has suggested that undergraduate delivery relies on lectures and is subject to clinical and staffing pressures. Many UK undergraduate students feel less than adequately prepared to manage dermatological conditions, and misconceptions about dermatology are common. Educators have called for innovative solutions, including small group teaching.

Legionella feeleii: an unusual organism associated with cutaneous infection in an immunocompromised patient.

We report a 23-year-old immunocompromised woman who, following cardiac transplantation, presented with an unusual cutaneous eruption. She developed a widespread pustular rash, systemic symptoms and a high temperature with raised inflammatory markers. The diagnosis was reached when a skin biopsy was cultured onto Legionella agar (buffered charcoal yeast extract) and Legionella feeleii was isolated.

Steady-state pharmacokinetics of hydroxychloroquine in patients with cutaneous lupus erythematosus.

Background Hydroxychloroquine (HCQ), a 4-aminoquinolone antimalarial, is regarded as the oral therapy of choice for cutaneous and systemic lupus erythematosus (SLE). It is also licensed for rheumatoid arthritis (RA). Studies of HCQ-treated patients with SLE or RA have demonstrated a positive correlation between whole-blood HCQ levels and clinical response.

Translating translation into patient benefit for atopic eczema.

This review considers, in the context of British Skin Foundation (BSF)-funded translational research into atopic eczema conducted in Newcastle, the complex interactions between clinical and non-clinical scientists in both academia and industry and how this may have impacted on clinical care. However, research in individual centres does not occur in isolation and clinically relevant outcomes from collaborative research are increasingly supported through regional and national networks. This is illustrated by our trial of azathioprine in adults with atopic eczema conducted across centres in the North East of England that employed pharmacogenetic dosimetry.

Tmem79/Matt is the matted mouse gene and is a predisposing gene for atopic dermatitis in human subjects.

Background: Atopic dermatitis (AD) is a major inflammatory condition of the skin caused by inherited skin barrier deficiency, with mutations in the filaggrin gene predisposing to development of AD. Support for barrier deficiency initiating AD came from flaky tail mice, which have a frameshift mutation in Flg and also carry an unknown gene, matted, causing a matted hair phenotype.

Objective: We sought to identify the matted mutant gene in mice and further define whether mutations in the human gene were associated with AD.

Long-term response to hydroxychloroquine in patients with discoid lupus erythematosus.

Background: The recommended first-line oral therapy for discoid lupus erythematosus (DLE) is the antimalarial hydroxychloroquine. To the best of our knowledge, there is no published information regarding the long-term (i.e.

Pyoderma gangrenosum: a rare cause of breast ulceration.

Breast ulceration is an alarming sign for clinicians and places a significant physical and psychological burden on the patient. We report a rare presentation of pyoderma gangrenosum of the breast in a patient known to have ulcerative colitis but no active underlying disease process and no history of breast tissue trauma. This case report with literature review highlights the importance of considering pyoderma gangrenosum as a differential diagnosis in breast ulcers.

Clinical and pharmacogenetic influences on response to hydroxychloroquine in discoid lupus erythematosus: a retrospective cohort study.

The recommended systemic therapy of choice for discoid lupus erythematosus (DLE) is the 4-aminoquinolone antimalarial hydroxychloroquine. There is limited published information on the likelihood of clinical response and, in particular, what factors influence outcome. We conducted a multicenter observational and pharmacogenetic study of 200 patients with DLE treated with hydroxychloroquine.

Measuring disease activity and damage in discoid lupus erythematosus.

Background: Discoid lupus erythematosus (DLE) is a disfiguring inflammatory skin disease. There is no specific tool for measuring disease severity.

Objectives: To determine the features needed in a score measuring activity and damage in DLE and to investigate the score's reliability and its correlation with the physician's global assessment of disease severity and the patient-reported Dermatology Quality of Life Index (DLQI).

Analysis of the individual and aggregate genetic contributions of previously identified serine peptidase inhibitor Kazal type 5 (SPINK5), kallikrein-related peptidase 7 (KLK7), and filaggrin (FLG) polymorphisms to eczema risk.

Background: Polymorphisms in the serine protease inhibitor gene serine peptidase inhibitor Kazal type 5 (SPINK5) and the serine protease kallikrein-related peptidase 7 gene (KLK7) appear to confer risk to eczema in some cohorts, but these findings have not been widely replicated. These genes encode proteins thought to be involved in the regulation of posttranslation processing of filaggrin (FLG), the strongest identified genetic risk factor for eczema to date.

Objectives: We sought to clarify the individual risk of eczema conferred by the SPINK5 polymorphism rs2303067 (Glu420Lys) and a previously described insertion in the 3' untranslated region of KLK7 and to examine potential epistatic effects between these variants and FLG mutations.

An open-label, dose-ranging study of methotrexate for moderate-to-severe adult atopic eczema.

Background: Treatment options for moderate-to-severe atopic eczema are limited. Although methotrexate (MTX) is a widely used and effective treatment for psoriasis, there have been no previous prospective trials of its use in refractory atopic eczema, despite a few small, retrospective reports suggesting that it is a well-tolerated and effective treatment.

Objectives: We have assessed the safety and efficacy of oral MTX in 12 adults with moderate-to-severe atopic eczema in an open-label, dose-ranging, prospective trial using objective outcome measures.

Null mutations in the filaggrin gene (FLG) determine major susceptibility to early-onset atopic dermatitis that persists into adulthood.

Atopic dermatitis (AD) is a common disease with a complex etiology in childhood and adult life. A significant proportion of childhood AD is transient, but in many cases it persists into adulthood. We have recently shown that null mutations in the filaggrin gene (FLG) are an important predisposing factor for childhood eczema and eczema-associated asthma, but persistence to adulthood has not been analyzed.

Elevated expression and genetic association links the SOCS3 gene to atopic dermatitis.

In a systematic analysis of global gene-expression patterns, we found that SOCS3 messenger RNA was significantly more highly expressed in skin from patients with atopic dermatitis than in skin from healthy controls, and immunohistochemical analysis confirmed a similar elevation of SOCS3 protein. Furthermore, we found a genetic association between atopic dermatitis and a haplotype in the SOCS3 gene in two independent groups of patients (P<.02 and P<.
