High Unemployment Rate in Patients with Hidradenitis Suppurativa despite High Educational Attainment.

BACKGROUND: Hidradenitis suppurativa (HS) is associated with lower socioeconomic status (SES). The adverse influence of HS on education and employment may explain this. It remains unknown whether HS causes downward social trajectories, i.e., social drift, or whether those affected are born into a lower SES. We aimed to assess the influence of HS on education and employment and compare the highest educational attainment of participants with their parents. METHODS: An anonymous online survey was distributed by patient-led organisations. Frequencies were compared with χ2 and disease interactions with one-way ANOVA. RESULTS: Among 335 respondents from 10 countries, 94.9% completed secondary/high school, 71.3% completed further education, 41.8% completed an undergraduate degree, 20% completed postgraduate education, 10.7% completed a masters, and 2.1% completed a doctorate. Participant education was greater than parental education (p < 0.001). Despite this, 24.2% were unemployed and 15.2% were receiving illness benefit. Compared to national statistics, HS participants from Ireland (p = 0.003), the USA (p < 0.001), and the UK (p < 0.001) were more likely to be unemployed/receiving illness benefit despite higher educational attainment in Ireland (p = 0.006) and the USA (p = 0.003) with similar education in the UK (p = 0.153). CONCLUSIONS: Social drift describes downward social trajectories due to the development of a disease. Participants in this study report greater education than their parents and the background population, but despite this, they are experiencing downward social trajectories with higher unemployment and receipt of illness benefit. Disease onset in HS tends to be at peak educational age. Education does not appear to be impaired by early disease with disease accumulation during employment years limiting opportunities.

Efficacy and safety of ciclosporin versus methotrexate in the treatment of severe atopic dermatitis in children and young people (TREAT): a multicentre parallel group assessor-blinded clinical trial.

BACKGROUND: Conventional systemic drugs are used to treat children and young people (CYP) with severe atopic dermatitis (AD) worldwide, but no robust randomized controlled trial (RCT) evidence exists regarding their efficacy and safety in this population. While novel therapies have expanded therapeutic options, their high cost means traditional agents remain important, especially in lower-resource settings. OBJECTIVES: To compare the safety and efficacy of ciclosporin (CyA) with methotrexate (MTX) in CYP with severe AD in the TREatment of severe Atopic Eczema Trial (TREAT) trial. METHODS: We conducted a parallel group assessor-blinded RCT in 13 UK and Irish centres. Eligible participants aged 2-16 years and unresponsive to potent topical treatment were randomized to either oral CyA (4 mg kg-1 daily) or MTX (0.4 mg kg-1 weekly) for 36 weeks and followed-up for 24 weeks. Co-primary outcomes were change from baseline to 12 weeks in Objective Severity Scoring of Atopic Dermatitis (o-SCORAD) and time to first significant flare (relapse) after treatment cessation. Secondary outcomes included change in quality of life (QoL) from baseline to 60 weeks; number of participant-reported flares following treatment cessation; proportion of participants achieving ≥ 50% improvement in Eczema Area and Severity Index (EASI 50) and ≥ 75% improvement in EASI (EASI 75); and stratification of outcomes by filaggrin status. RESULTS: In total, 103 participants were randomized (May 2016-February 2019): 52 to CyA and 51 to MTX. CyA showed greater improvement in disease severity by 12 weeks [mean difference in o-SCORAD -5.69, 97.5% confidence interval (CI) -10.81 to -0.57 (P = 0.01)]. More participants achieved ≥ 50% improvement in o-SCORAD (o-SCORAD 50) at 12 weeks in the CyA arm vs. the MTX arm [odds ratio (OR) 2.60, 95% CI 1.23-5.49; P = 0.01]. By 60 weeks MTX was superior (OR 0.33, 95% CI 0.13-0.85; P = 0.02), a trend also seen for ≥ 75% improvement in o-SCORAD (o-SCORAD 75), EASI 50 and EASI 75. Participant-reported flares post-treatment were higher in the CyA arm (OR 3.22, 95% CI 0.42-6.01; P = 0.02). QoL improved with both treatments and was sustained after treatment cessation. Filaggrin status did not affect outcomes. The frequency of adverse events (AEs) was comparable between both treatments. Five (10%) participants on CyA and seven (14%) on MTX experienced a serious AE. CONCLUSIONS: Both CyA and MTX proved effective in CYP with severe AD over 36 weeks. Participants who received CyA showed a more rapid response to treatment, while MTX induced more sustained disease control after discontinuation.

Association of Biologic Treatment in Hidradenitis Suppurativa With Reduced Neutrophil-Lymphocyte Ratio and Platelet-Lymphocyte Ratio.

This cohort study assesses whether an association exists between biologic treatment for hidradenitis suppurativa and neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, and monocyte-lymphocyte ratio.

'More extraordinary than mundane ' A phenomenological analysis of the experiences of individuals living with CLE and their taking care in the sun.

INTRODUCTION: CLE is a chronic inflammatory autoimmune condition of which photosensitivity is a major symptom. Individuals living with CLE are advised to practice photoprotection. Despite the benefits for disease control, many individuals living with CLE do not practice optimal photoprotection. The aim of this study was to gain a deep insight into the lived experiences of individuals with CLE and their photoprotective practices. METHODS: A qualitative study approach was conducted, using Hermeneutic phenomenology. Individuals living with CLE were recruited and interviewed. Rich pictures were used to enrich the interviews. Interviews were transcribed and analysed using Template Analysis. RESULTS: Analysis revealed four themes: 'Much more than just a photosensitive skin condition', 'The impact of sun on CLE and social dynamics', 'Drifting to the sun: personal transitions and social norms' and 'Taking care in the sun: easier said than done'. DISCUSSION AND CONCLUSION: This study provides a nuanced insight into the lived experiences of individuals with CLE and their photoprotective practices. Taking care in the sun is not a simplistic process. Beyond the biomedical model of illness, the social impact that CLE has on individuals has a dominant influence on their photoprotective behaviours. Such insights could help healthcare professionals tailor photoprotective advice.

Evaluation of the clinical impact of repeat application of hydrogel-forming microneedle array patches.

Hydrogel-forming microneedle array patches (MAPs) have been proposed as viable clinical tools for patient monitoring purposes, providing an alternative to traditional methods of sample acquisition, such as venepuncture and intradermal sampling. They are also undergoing investigation in the management of non-melanoma skin cancers. In contrast to drug or vaccine delivery, when only a small number of MAP applications would be required, hydrogel MAPs utilised for sampling purposes or for tumour eradication would necessitate regular, repeat applications. Therefore, the current study was designed to address one of the key translational aspects of MAP development, namely patient safety. We demonstrate, for the first time in human volunteers, that repeat MAP application and wear does not lead to prolonged skin reactions or prolonged disruption of skin barrier function. Importantly, concentrations of specific systemic biomarkers of inflammation (C-reactive protein (CRP); tumour necrosis factor-α (TNF-α)); infection (interleukin-1ß (IL-1ß); allergy (immunoglobulin E (IgE)) and immunity (immunoglobulin G (IgG)) were all recorded over the course of this fixed study period. No biomarker concentrations above the normal, documented adult ranges were recorded over the course of the study, indicating that no systemic reactions had been initiated in volunteers. Building upon the results of this study, which serve to highlight the safety of our hydrogel MAP, we are actively working towards CE marking of our MAP technology as a medical device.

Helping doctors in training to STEP-UP: A leadership and quality improvement programme in the Belfast Health and Social Care Trust.

INTRODUCTION: Medical engagement in healthcare organisations can improve service development and patient experience. Doctors in training have limited opportunities to engage in service improvement work and develop leadership skills. METHOD: We describe the Specialist Trainees Engaged in Leadership Programme (STEP), a programme developed to introduce concepts of medical leadership and quality improvement skills in the Belfast Trust. STEP started in 2013 and over 140 trainees have now participated in the programme. RESULTS: Over 42 quality improvement projects have been completed with the support of the programme. Evaluation of STEP has demonstrated an improvement across all domains explored throughout the duration of the programme, with benefits for the individual trainee and the wider organisation. DISCUSSION: We describe the programme in detail. The STEP curriculum can easily be adapted to meet the needs of NHS trainees, allowing them to understand the objectives and strategy of their employers and improve their ability to plan and deliver safe, effective, patient-centred care.

Pyoderma Gangrenosum: A Rare Cause of Cutaneous Ulceration and One Easily Misdiagnosed.

Pyoderma gangrenosum (PG) is a rare inflammatory neutrophilic dermatosis often misdiagnosed. It is uncommon in infants and children accounting for 4% of cases. A one-year-old male in paediatric ICU ventilated for bronchopneumonia was referred with ulcerated areas on his neck and axilla corresponding to sites of recent removal of central and arterial lines. Examination revealed areas of deep ulceration with violaceous undermined borders in keeping with PG. This was supported by a skin biopsy showing a neutrophilic infiltrate in the deeper dermis. Topical clobetasol propionate was commenced and a dramatic improvement within 24 hours noted. Blood results showed a leucocytosis of 29.7; a differential WCC showed toxic granulation in neutrophils with myeloid left shift; immunoglobulins showed elevated IgG 23 and IgA 4.86. The elevated WCC made us consider a leukaemic trigger; however, they settled with treatment of the underlying infection. PG in children is more likely to have an atypical distribution involving the head and neck (26.6%) or buttocks (15%). An interesting feature in this case is the presence of pathergy, a term used to describe the induction or exacerbation of PG at sites of iatrogenic or incidental trauma. It is seen in 31% of patients with PG.

SMAD inhibition attenuates epithelial to mesenchymal transition by primary keratinocytes in vitro.

Epithelial to mesenchymal transition (EMT) is a process whereby epithelial cells undergo transition to a mesenchymal phenotype and contribute directly to fibrotic disease. Recent studies support a role for EMT in cutaneous fibrotic diseases including scleroderma and hypertrophic scarring, although there is limited data on the cytokines and signalling mechanisms regulating cutaneous EMT. We investigated the ability of TGF-ß and TNF-α, both overexpressed in cutaneous scleroderma and central mediators of EMT in other epithelial cell types, to induce EMT in primary keratinocytes and studied the signalling mechanisms regulating this process. TGF-ß induced EMT in normal human epidermal keratinocytes (NHEK cells), and this process was enhanced by TNF-α. EMT was characterised by changes in morphology, proteome (down-regulation of E-cadherin and Zo-1 and up-regulation of vimentin and fibronectin), MMP secretion and COL1α1 mRNA expression. TGF-ß and TNF-α in combination activated SMAD and p38 signalling in NHEK cells. P38 inhibition with SB203580 partially attenuated EMT, whereas SMAD inhibition using SB431542 significantly inhibited EMT and also reversed established EMT. These data highlight the retained plasticity of adult keratinocytes and support further studies of EMT in clinically relevant in vivo models of cutaneous fibrosis and investigation of SMAD inhibition as a potential therapeutic intervention.

Keratinocyte growth factor promotes epithelial survival and resolution in a human model of lung injury.

RATIONALE: Increasing epithelial repair and regeneration may hasten resolution of lung injury in patients with the acute respiratory distress syndrome (ARDS). In animal models of ARDS, keratinocyte growth factor (KGF) reduces injury and increases epithelial proliferation and repair. The effect of KGF in the human alveolus is unknown. OBJECTIVES: To test whether KGF can attenuate alveolar injury in a human model of ARDS. METHODS: Volunteers were randomized to intravenous KGF (60 µg/kg) or placebo for 3 days, before inhaling 50 µg LPS. Six hours later, subjects underwent bronchoalveolar lavage (BAL) to quantify markers of alveolar inflammation and cell-specific injury. MEASUREMENTS AND MAIN RESULTS: KGF did not alter leukocyte infiltration or markers of permeability in response to LPS. KGF increased BAL concentrations of surfactant protein D, matrix metalloproteinase (MMP)-9, IL-1Ra, granulocyte-macrophage colony-stimulating factor (GM-CSF), and C-reactive protein. In vitro, BAL fluid from KGF-treated subjects inhibited pulmonary fibroblast proliferation, but increased alveolar epithelial proliferation. Active MMP-9 increased alveolar epithelial wound repair. Finally, BAL from the KGF-pretreated group enhanced macrophage phagocytic uptake of apoptotic epithelial cells and bacteria compared with BAL from the placebo-treated group. This effect was blocked by inhibiting activation of the GM-CSF receptor. CONCLUSIONS: KGF treatment increases BAL surfactant protein D, a marker of type II alveolar epithelial cell proliferation in a human model of acute lung injury. Additionally, KGF increases alveolar concentrations of the antiinflammatory cytokine IL-1Ra, and mediators that drive epithelial repair (MMP-9) and enhance macrophage clearance of dead cells and bacteria (GM-CSF). Clinical trial registered with ISRCTN 98813895.

Efficacy of topical PUVA soaks for palmoplantar dermatoses: an audit.

BACKGROUND: With a lack of evidence base for individual topical PUVA protocols, treatment is presently based on the consensus of current practice. This audit was designed to investigate the effectiveness of topical PUVA for palmoplantar dermatoses. METHODS: Phototherapy notes were reviewed on all patients who received hand and/or foot PUVA 2002-2007 in the Northern Health and Social Care Trust (NHSCT), Northern Ireland. RESULTS: Thirty patients met the inclusion criteria for the study. The mean number of treatments, maximum single UVA dose, and cumulative dose, were 18.4, 4.2 J/cm2, and 48.3 J/cm2, respectively. A positive response to treatment occurred in 51.3% of patients, which fell short of the 70% standard set. In a multivariate logistic regression analysis, number of treatments (P=0.04) and maximum single UVA dose (P=0.03) were the only variables associated with positive treatment outcome. The response was not influenced significantly by skin type, concurrent topical treatments, or cumulative UVA dose. Limitations to the study: Small patient numbers may have prevented the statistical significance of individual variables. CONCLUSIONS: UV dose increments should be clearly defined to avoid excess caution at the expense of an adequate patient response, and a minimum of 20 treatments administered to all patients, if tolerated.
