RESUMEN

BACKGROUND: Real-world data evaluating effectiveness and persistence of systemic therapies for patients with psoriasis are limited. Objectives To determine the effectiveness and persistence of acitretin, ciclosporin, fumaric acid esters (FAEs) and methotrexate in patients with moderate-to-severe psoriasis. METHODS: Data from the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR), a prospective, multicentre pharmacovigilance register of patients with moderate-to-severe psoriasis receiving biologic and/or conventional systemic therapies, were analysed. Eligible patients were ≥ 16 years of age receiving a first course of acitretin, ciclosporin, FAEs or methotrexate between 2007 and 2021 with ≥ 6 months' follow-up. Effectiveness was defined as achieving absolute Psoriasis Area and Severity Index (aPASI) ≤ 2 reported ≥ 4 weeks after treatment start date until date of cessation. To identify baseline clinical variables associated with treatment effectiveness, we used multivariable logistic regression models estimating the adjusted odds ratio (aOR) of achieving aPASI ≤ 2. To describe drug persistence associated with ineffectiveness, occurrence of adverse events or other reasons for discontinuation, survival estimates with 95% confidence intervals (CIs) were obtained using a flexible parametric model. Results were obtained using multiple imputed data. RESULTS: In total, 5430 patients were included in the analysis. Overall, 1023 (19%) patients were receiving acitretin, 1401 (26%) patients were on ciclosporin, 347 (6%) patients were on FAEs, and 2659 (49%) patients were receiving methotrexate at registration. The proportion of patients who achieved aPASI ≤ 2 was lower for those treated with acitretin [n = 118 (21%)] compared with those receiving ciclosporin [n = 233 (34%)], FAEs [n = 43 (29%)] and methotrexate [n = 372 (32%)]. Factors associated with ineffectiveness included prior experience to previous nonbiologic systemic therapies (acitretin) (aOR 0.64, 95% CI 0.42-0.96), male sex (methotrexate) (aOR 0.58, 95% CI 0.46-0.74), comorbidities (aOR 0.70, 95% CI 0.51-0.97) and alcohol consumption (≤ 14 units per week) (ciclosporin) (aOR 0.70, 95% CI 0.50-0.98). Persistence associated with all reasons for discontinuation showed better survival for methotrexate compared with acitretin, ciclosporin and FAEs cohorts at 12 months [survival estimate 46.1 (95% CI 44.0-48.3), 31.9 (95% CI 29.4-34.7), 30.0 (95% CI 27.5-32.4) and 35.0 (95% CI 29.9-40.9), respectively]. CONCLUSIONS: The real-world effectiveness and persistence of acitretin, ciclosporin, FAEs and methotrexate were generally low. Previous nonbiologic systemic therapies, male sex, comorbidities and alcohol consumption were risk factors associated with treatment ineffectiveness.

RESUMEN

Primary localized cutaneous amyloidosis is a group of rare conditions where amyloid deposition is limited to the skin without systemic manifestations. Most cases are sporadic; however, mutations in the oncostatin M receptor (OSMR) and interleukin-31 receptor A (IL31RA) genes can cause a familial form of the condition in up to 10% of cases. Here, we describe a family in which 8 female individuals are affected by either macular amyloidosis or amyloidosis cutis dyschromica. To the best of our knowledge, a sex-specific expression or the coexistence of 2 different phenotypes of primary localized cutaneous amyloidosis in 1 pedigree has not yet been reported.

RESUMEN

Mycosis fungoides (MF), the most common cutaneous T-cell lymphoma (CTCL), is rare in childhood. The prognosis and response to treatment are poorly described in children. The objective of the current study was to evaluate the response to phototherapy in a pediatric cohort. A retrospective cohort study of all patients diagnosed with MF before the age of 18 years and referred to the regional CTCL phototherapy service was performed between January 1990 and April 2012. Twenty-eight patients were identified (13 boys, 15 girls). The mean age at presentation was 11.6 ± 3.9 years. The hypopigmented variant was noted in 79% of patients. All patients had stage I disease (IA = 10, IB = 17, unknown = 1). The median follow-up after diagnosis was 43 months (range 6-274 mos). Narrowband ultraviolet B (NbUVB; 311 nm) was used as first-line phototherapy in 18 patients and psoralen (bath) plus ultraviolet A (PUVA) was used in 8 patients. Complete or partial response was observed in 19 of 22 patients (86%). A further course of phototherapy was required in 7 of 12 patients (58%) treated with NbUVB after a median of 4 months (range 4-29 mos). A further course of phototherapy was required in four of eight patients (50%) successfully treated with PUVA after a median of 45.5 months (range 30-87 mos). No disease progression was noted over the follow-up (median 43 mos). The majority of patients in our cohort had hypopigmented MF. Phototherapy offers an effective option for treatment of childhood MF, although the period of remission may be greater in patients treated with PUVA.

RESUMEN

Epidemiological studies of severe drug hypersensitivities are important to understanding the morbidity and mortality of this heterogeneous group of disorders. These insights also allow greater identification of at-risk patient groups. However, epidemiological studies of drug hypersensitivity reactions are challenging due to the variable diagnostic criteria applied and incomplete data sets studied. We review the epidemiology of severe drug hypersensitivity reactions with a particular focus on severe cutaneous adverse reactions (SCARs). SCAR diseases include: Stevens-Johnson syndrome, toxic epidermal necrolysis, drug rash eosinophilia and systemic symptoms, serum-sickness-like reaction and acute generalized exanthematous pustulosis.

RESUMEN

The objective of this guideline is to provide up-to-date, evidence-based recommendations for the management of SLE that builds upon the existing treatment guideline for adults living with SLE published in 2017. This will incorporate advances in the assessment, diagnosis, monitoring, non-pharmacological and pharmacological management of SLE. General approaches to management as well as organ-specific treatment, including lupus nephritis and cutaneous lupus, will be covered. This will be the first guideline in SLE using a whole life course approach from childhood through adolescence and adulthood. The guideline will be developed with people with SLE as an important target audience in addition to healthcare professionals. It will include guidance related to emerging approved therapies and account for National Institute for Health and Care Excellence Technology Appraisals, National Health Service England clinical commissioning policies and national guidance relevant to SLE. The guideline will be developed using the methods and rigorous processes outlined in 'Creating Clinical Guidelines: Our Protocol' by the British Society for Rheumatology.

RESUMEN

In excess of three quarters of patients with psoriatic arthritis (PsA) have preceding psoriasis (PsO), which offers a clinical biomarker for the recognition of early PsA. Numerous surveys have shown a remarkably high frequency of clinically occult musculoskeletal symptoms in psoriasis patients. Imaging studies, particularly ultrasound, show a high prevalence of subclinical enthesitis and other inflammatory changes in psoriasis subjects. Since a serum biomarker, such as the case of anti-citrullinated protein antibodies (ACPA) in rheumatoid arthritis, neither exists nor seems biologically plausible at this point, this article explores how integration of rheumatological and dermatological assessment can be facilitated for the early recognition of potential PsA. Given that scalp disease is a PsA predictor, but may be managed in the community, then a particular need to access this group is needed. An integrated approach between rheumatology and dermatology can involve joint clinics, parallel clinics with discussion of relevant cases or virtual contact between specialties. Early therapy evaluation and integrated strategies have considerable implications for minimizing suffering and joint damage in PsA.

RESUMEN

BACKGROUND: Pemphigus herpetiformis (PH) is a rare subtype of pemphigus that presents challenges in diagnosis. OBJECTIVE: To review the presentation, diagnosis, and management of PH. METHODS: We reviewed the charts of all patients diagnosed and treated for PH in an immunobullous referral center between September 2007 and June 2013. RESULTS: Eight patients were identified with a diagnosis of PH. All presented initially with pruritus. Clinical disease was manifest as either urticated erythematous plaques or a vesiculobullous eruption. Histological evaluation demonstrated eosinophilic spongiosis in all patients with acantholysis in half of cases (n = 4/8). Peripheral eosinophilia was noted in three of eight (37.5%) patients. In all cases, direct immunofluorescence showed intercellular deposition of immunoglobulin G in the epidermis. All patients required high-dose corticosteroid initially. All patients treated with dapsone or sulfasalazine (n = 4) achieved at least partial control. Other effective treatments included intravenous immunoglobulin (n = 2), azathioprine (n = 2), and leflunomide (n = 1). Rituximab was ineffective in two patients. CONCLUSION: The clinical and histological features of PH develop over time and with treatment, making distinction between pemphigus subtypes challenging and delay in diagnosis common. Diagnosis of PH requires a high index of suspicion and is made on clinical grounds (urticated erythema) in the context of compatible histology and immunofluorescence findings. Treatment may be challenging, although efficacy of sulfonamide derivatives appears to offer a therapeutic effect.

RESUMEN

IMPORTANCE: Dermatologists are using an increasing range of immunomodulatory therapies to treat an expanding number of skin diseases. Complications of therapy are broad and include infection. Cytomegalovirus (CMV) retinitis has not been reported in association with dermatologic disease. OBSERVATIONS: We report two cases of CMV retinitis associated with immunosuppression for eczema and pemphigus vulgaris. In both cases, patients were receiving corticosteroid and a second-line immunosuppressive agent (cyclosporine or mycophenolate mofetil). Disease presented in both patients with painless visual loss. CONCLUSIONS AND RELEVANCE: Patients receiving immunosuppressive therapy should be monitored for blurred vision, floaters, or visual loss and referred for urgent assessment to ensure accurate diagnosis and prompt treatment of possible CMV retinitis.

RESUMEN

Psoriasis is a common chronic inflammatory disease of the skin that has a significant impact on quality of life. A small number of systemic therapies are well established in psoriasis management. These have immunosuppressive and/or anti-proliferative effects on the skin and immune system. As understanding of the pathogenesis of psoriasis has advanced over the last 2 decades, there has been clearer appreciation of the genetic, cellular and immunological components of disease expression, which has provided new insight into potential therapeutic targets, including the development of biological therapies. Biologics offer a unique opportunity to block or inhibit specific key components of psoriasis pathogenesis. The introduction of tumour necrosis factor (TNF).α and interleukin (IL)-12/-23 inhibitors has resulted in remarkable clinical responses in patients with severe psoriasis and has led to the development of a range of other cytokine modulators currently undergoing investigation. More recently, research in keratinocyte biology and immune cell function, particularly intracellular signalling, has afforded additional opportunities to develop a range of small-molecule oral preparations that may prove effective in disease control. This paper reviews current and emerging systemic treatments in the management of psoriasis.

RESUMEN

BACKGROUND: UK medical graduates are required to reach standards defined by the General Medical Council (in Tomorrows Doctors) in all specialties, including dermatology. AIMS: We assessed the self-reported competence of Foundation Year 1 (FY1) doctors in the diagnosis and management of skin disease correlated against their undergraduate dermatology experience. METHODS: The FY1 doctors attending a teaching programme were surveyed at six hospital sites throughout the North Western Deanery. Questionnaires were completed on self-reported competence in learning outcomes defined by the British Association of Dermatologists (BAD). Information recorded previous undergraduate teaching (duration and delivery), and whether they felt sufficiently prepared to diagnose and manage patients with skin disease in their clinical practice. RESULTS: Of 174 FY1 doctors, 118 attended the teaching sessions. All of the attendees completed a questionnaire. Trainees who undertook longitudinal placements in dermatology (defined as 10 or more half days of clinical experience) regarded themselves significantly more prepared to practise for their stage of training: 61 per cent compared with 8.9 per cent (χ(2) = 32.8, df = 1, p < 0.05). Furthermore, these trainees rated their abilities in basic history taking, clinical examination, management of dermatological emergencies and diagnosis of skin malignancy as being greater than those who had not experienced longitudinal placements in the specialty. CONCLUSIONS: Longitudinal placements in dermatology offer undergraduates experience in the diagnosis and management of skin disease that develops confidence for foundation practice.

RESUMEN

Management of psoriasis over the last decade has changed significantly with the introduction of biological therapies. Ustekinumab is a first-in-class biological agent, inhibiting the action of IL-12 and IL-23, and has provided further evidence for the role of Th1 and Th17 lymphocytes in the pathogenesis of psoriasis. Efficacy has been clearly demonstrated in three Phase III clinical trials. Week 12 Psoriasis Area and Severity Index (PASI) 75 was observed in 66.4-75.7% of patients with PASI 90 achieved in 36.7-50.9%. This marked clinical response is also reflected in a significant improvement in quality of life. The most recent Phase III clinical trial has demonstrated the superior efficacy of ustekinumab (regardless of dosing regimen) compared with high-dose etanercept at week 12. Long-term efficacy has been demonstrated over 148 weeks with 64-76% of patients maintaining PASI 75. The role of ustekinumab in the treatment of psoriatic arthritis has shown some benefit in Phase II clinical trials. Phase III clinical trials are pending and will provide further guidance on management of concurrent disease. The currently available safety data are on the whole reassuring, although ongoing vigilance remains central to the detection of rare or late sequelae.

RESUMEN

IMPORTANCE OF THE FIELD: The majority of patients with psoriasis can be safely and effectively treated with topical therapy alone, either under the supervision of a family physician or dermatologist. For those requiring systemic agents, topical therapies can provide additional benefit. Optimal use of topical therapy requires an awareness of the range and efficacy of all products. AREAS COVERED IN THIS REVIEW: The review covers the efficacy and role of topical therapies including emollients, corticosteroids, vitamin D analogs, calcineurin inhibitors, dithranol, coal tar, retinoids, keratolyics and combination therapy. The report was prepared following a PubMed and Embase literature search up to April 2010. WHAT THE READER WILL GAIN: The paper provides a broad review of the relevant topical therapeutic options available in routine clinical practice for the management of psoriasis and a recommendation for selection of treatment. TAKE HOME MESSAGE: Topical therapies used appropriately provide a safe and effective option for the management of psoriasis. An awareness of the available products and their efficacy is key to treatment selection and patient satisfaction.

RESUMEN

Psoriasis is a common, chronic inflammatory skin disease which is associated with a number of significant co-morbidities including: impairment of quality of life; cardiovascular disease; and a seronegative arthritis known as psoriatic arthritis. Our understanding of the pathogenesis of psoriasis has developed at a remarkable rate in recent years. These new insights have significantly changed our perception of the condition and have led to the development of several new treatment strategies. Biological agents have proved a major step forward in therapeutic options for psoriasis. The ability to clear, or almost clear, cutaneous disease has changed the outcomes and expectations of many patients with this disease. The impact on both physical and psychological health may be great. This review covers the clinical features and management of psoriasis with specific reference to new therapeutic options.
