Treatments for atopic dermatitis.

Risk of myocardial infarction, ischemic stroke, and cardiovascular death in patients with atopic dermatitis

To introduce and determine the clinical benefits of a detoxification program that combines fasting with fluid therapy for refractory cases of severe atopic dermatitis (AD), we performed a retrospective chart review of inpatients with AD from March 2010 to February 2012 at the Department of Ophthalmology, Otorhinolaryngology and Dermatology of Korean Medicine in the Kyung Hee Medical Center. Patients were treated with the detoxification program, which combined fasting with fluid therapy, and herbal medicine, herbal wet wrap dressings, or acupuncture treatment when clinically necessary. The primary outcome was the SCORAD total index. The secondary outcome was the pruritus visual analogue scale (VAS) score in SCORAD as evaluated by a trained dermatology specialist. Among the 130 inpatients that have done detoxification, 7 patients met the inclusion criteria. The mean total SCORAD scores significantly decreased from 64.67 ± 11.72 to 26.26 ± 11.01 (P = 0.018) after the detoxification program. There was also a significant decrease in VAS score for pruritus from 8.00 ± 1.16 to 2.57 ± 0.98 (P = 0.016) between admission and discharge. We suggest that fasting with fluid therapy as a complementary and alternative treatment method may provide some benefits for patients with refractory cases of severe atopic dermatitis.

What's new in atopic dermatitis?

To present the most recent evidence on atopic dermatitis and its relation to food allergy. Atopic dermatitis is a chronic inflammatory disorder of the skin characterized by impaired skin barrier because of multifactorial causes including genetic factors, immune dysregulation, and skin microbiome dysbiosis. Infants with temporary skin barrier disruption and/or persistent atopic dermatitis are particularly at risk of developing food allergy (during the so-called atopic march), with up to half of patients demonstrating positive food-specific IgE and one-third of severe cases of atopic dermatitis having positive symptoms on oral food challenge. A high proportion of children with atopic dermatitis exhibit asymptomatic sensitization to foods, and skin testing to identify potential food triggers is not recommended unless the patient has a history suggestive of food allergy and/or moderate-to-severe atopic dermatitis unresponsive to optimal topical care. Indeed, indiscriminate testing can lead to a high proportion of false-positive tests and harmful dietary evictions. Promising strategies to prevent food allergy in children with atopic dermatitis include early skincare with emollients and treatment with topical steroid, and early introduction of highly allergenic foods. Further studies are required to identify risk factors for atopic dermatitis to help prevent the development of food allergy in this high-risk population.

Background/Aims: Cyclosporin A is useful in the treatment of psoriasis, atopic dermatitis and other dermatoses. The aim of this long-term study was to investigate the usefulness of cyclosporin A in the treatment of severe and therapy-resistant atopic dermatitis and also in pahnoplantar pustulosis.Methods: This study was performed in two series, one of 18 patients with severe atopic dermatitis, the other one of 36 patients with palmar or palmoplantar pustulosis. In both series the schedule of treatment consisted of four consecutive stages: in the first stage the patients received cyclosporin A 2.5 mg/kg per day for 3 months; in the second stage 2 mg/kg per day for 6 months; in the third stage 1.2 mg/kg per day also for 6 months; and in the fourth stage the doses were the same as in the third but on alternate days. The fifth stage was a follow-up period, 9 months for patients without recurrences until then and 3 months if there was any recurrence or if the patient had relapsed in an earlier stage.Results: This regimen of treatment was effective in 91.6% of cases of palmoplantar pustulosis and in 73.7% of cases of severe atopic dermatitis. Side-effects, when present, were slight.Conclusion: A low dose treatment regimen of CyA is both efficient and has very few side effects.

Atopic dermatitis is a common, chronic pruritic condition affecting both children and adults, which has a negative impact on the quality of life. These guidelines were developed by an expert workgroup appointed by the Dermatological Society of Singapore, to provide doctors with information to assist in the management of their patients with atopic dermatitis. The workgroup members are experienced dermatologists with interest and expertise in eczemas. Workgroup members arrived at a consensus on the topics to be included. Relevant studies from the literature were assessed for best evidence, supplemented by the collective experience of the workgroup. For mild atopic dermatitis, emollients, mild potency topical steroids and topical calcineurin inhibitors are recommended. For moderate-to-severe atopic dermatitis, the use of emollients, moderate-to-potent topical steroids, topical calcineurin inhibitors, wet dressings, antimicrobials for secondary skin infection, phototherapy, and systemic therapy (e.g. prednisolone, cyclosporine, azathioprine or methotrexate) may be warranted. Patients with moderate-to-severe atopic dermatitis should be managed in conjunction with a dermatologist. Good outcomes can be achieved with an individualised therapeutic approach combined with adequate patient and parental education.

PSY17 The Prevalence and Clinical Profile of Atopic Dermatitis (AD) in England: A Population Based Linked Cohort Study Using Clinical Practice Research Datalink (CPRD) and Hospital Episode Statistics (HES)

Introduction: Atopic dermatitis (AD) is a complex disease with a variety of possible treatment regimens. The study objective was to demonstrate that methoxsalen used in conjunction with the Uvar XTS photopheresis system (Therakos, Exton, Pa., USA) is safe and can have a clinical effect on the skin manifestations and the quality of life in patients with severe, refractory AD. Methods: Single-arm, open-label treatment using the Uvar XTS photopheresis system. Seven patients (4 male and 3 female, median age: 47 years) with severe (SCORAD >45) AD of at least 12 months duration who in the preceding 12 months had been refractory to all 3 of the first-line therapies for AD, i.e. topical steroids, topical calcineurin inhibitors and one form of phototherapy (UVA, UVB or PUVA), or to one of the second-line therapies like systemic steroids or cyclosporine were included in the study. Treatment consisted of two extracorporeal photopheresis treatments (ExP) on successive days every 2 weeks for a minimum of 12 weeks to a maximum of 20 weeks. Quality of life assessment was performed with the SF-36 Health Survey and the Functional Assessment of Chronic Illness Therapy FACT-G Survey. Clinical improvement was documented with SCORAD assessment. Results: ExP led to a significant decrease in the SCORAD score from 77.7 after 10 cycles to 55.6. Patients reported that they had begun to notice improvement of their skin conditions after 5 cycles of photopheresis. The FACT-G score showed significant improvement from 64.8 to 72.9 (p < 0.05) and the SF-36 Health Survey showed significant improvement in the emotional well-being subscores (p < 0.05). Conclusions: ExP can have a significant therapeutic effect on the skin and quality of life improvement in a selected group of patients with severe AD who are refractory to conventional forms of therapy. However, larger studies are needed to further evaluate its therapeutic potential.

Guidelines of care for the management of atopic dermatitis in pediatric patients.

Atopic dermatitis is the most common chronic inflammatory skin disease of childhood and is increasing in prevalence throughout the world. Morbidity and resource use for atopic dermatitis are comparable to other chronic diseases. Topical corticosteroids are first-line therapeutic agents for atopic dermatitis; topical calcineurin inhibitors are considered second-line agents for patients who are older than 2 years. The aims of this study were to examine trends in visits for atopic dermatitis in children in the United States between 1997 and 2004, identify factors that were associated with a pediatric visit for atopic dermatitis, and assess changes in the treatment of atopic dermatitis over time. Visits for atopic dermatitis by children (0-18 years) to office-based physicians and hospital outpatient departments using 1997-2004 National Ambulatory Medical Care Survey and National Hospital Ambulatory Care Survey databases were analyzed. Medication prescribing rates during 2 time periods (1997-2000 and 2001-2004) were also analyzed. There were an estimated 7.4 million visits for atopic dermatitis. Statistically significant differences in patients with atopic dermatitis included age 2 to 5 years, black race, Asian race, and specialist or hospital outpatient clinic evaluation. The increase in atopic dermatitis visits per year was statistically significant. No statistical differences in prescribing rates were identified between the 2 time periods. Between 1997 and 2000, topical corticosteroids were prescribed in 34% of visits, decreasing to 25% between 2001 and 2004. Between 2001 and 2004, topical calcineurin inhibitors were prescribed in 23% of visits. In the same period, topical corticosteroids were prescribed in 24% of visits by children who were younger than 2 years; topical calcineurin inhibitors were prescribed in 22% of visits. Visits for atopic dermatitis in children are increasing. A recommended first-line treatment was prescribed in a minority of the visits.

CBP-201 is a next-generation monoclonal antibody targeting the IL-4Rα subunit. Rapid efficacy with CBP-201 was demonstrated in global phase 2 (WW001) and China-only pivotal trials (CN002) in patients with moderate-to-severe atopic dermatitis (AD). Previous studies of AD therapy demonstrated similar efficacy between moderate and severe disease, with a trend toward greater improvement in moderate patients. It is unknown whether there are differences in clinical response to CBP-201 with moderate vs.severe AD. We report post hoc efficacy analyses at Week 16 with CBP-201 300 mg from WW001 in baseline severity subgroups, based on validated Investigator Global Assessment (vIGA™) scores of 3 (moderate) and 4 (severe). In WW001 (NCT04444752), adults with moderate-to-severe AD were enrolled in a RDBPC 16-week trial of subcutaneous CBP-201 or placebo. For post hoc analysis, data for 300 mg every 2- and 4-week dose regimens were pooled. Investigators assessed AD severity using Eczema Area and Severity Index (EASI), SCORing AD (SCORAD), percent Body Surface Area (BSA) of AD involvement and vIGA. Patient-reported outcomes were assessed with the Dermatology Life Quality Index (DLQI) and Patient Oriented Eczema Measure (POEM). Least squares mean (LSM) score changes were analysed using ANCOVA modeling (including treatment, baseline score and baseline vIGA), with missing data interpolated by last observation carried forward. Responder endpoints were analysed using Clopper–Pearson methodology and, for missing values, nonresponder imputation. P-values are for CBP-201 vs. placebo, per baseline severity subgroup, at Week 16. At baseline, 113 patients had moderate AD (n = 74 CBP-201, n = 39 placebo) and 56 patients had severe AD (n = 39 CBP-201, n = 17 placebo). Baseline EASI scores were lower in the moderate subgroup [mean (SD): CBP-201, 21.5 (7.0); placebo, 22.2 (6.3)] vs. the severe subgroup [CBP-201, 33.6 (11.9); placebo, 31.9 (10.8)]. In both the moderate and severe AD subgroups, significant improvements with CBP-201 vs. placebo were observed. Except for the proportion of patients achieving vIGA 0/1, numerically greater CBP-201 responses were observed in patients with severe vs. moderate AD at Week 16; placebo responses were comparable per subgroup. In the severe and moderate subgroups, LSM SCORAD scores decreased by −42.8% (severe) and −29.8% (moderate), and LSM percent BSA decreased by −29.8% and −17.3%, respectively. Clinically meaningful 2-point improvement in vIGA was reported for 48.7% and 27.0% of patients with severe and moderate AD, respectively. The proportions of patients achieving vIGA 0/1, with 2-point improvement, were 20.5% and 27.0% with severe and moderate AD, respectively. Numerically greater proportions of patients with severe vs. moderate AD experienced EASI responses with CBP-201: EASI-50, 66.7% vs. 54.1%; EASI-75, 53.8% vs. 39.2%; EASI-90, 28.2% vs. 23.0%. Patients with severe vs. moderate AD reported greater improvements in patient reported outcomes with CBP-201: DLQI, −8.7 vs. −7.0; POEM, −12.5 vs. −8.7. Clinically meaningful improvements were observed in patients with AD with either moderate or severe AD after 16 weeks of treatment with CBP-201 300 mg at either 2- or 4-week dosing. There were no differences noted between moderate and severe patients in the placebo treatment group. In most severity readouts, greater proportions of patients with AD with severe disease on study entry experienced clinically meaningful improvements with CBP-201. In future CBP-201 trials, a more severe AD population needs to be examined to determine if this same observation is also noted. Collectively, the WW001 findings support further investigation of CBP-201, at both the 2- and 4-week dosing schedules enrolling larger numbers of moderate and severe patients with AD and with prespecified analyses by baseline AD severity.

Introduction. Atopic dermatitis (AtD) is one of the most common skin diseases in the world and its frequency is increasing. This is one of the few diseases that debuts in infancy, and can persist throughout life, worsening its quality, and sometimes leading to disability. Therefore, the treatment of atopic dermatitis remains an urgent problem in allergology and pediatrics in general. Traditionally, the treatment of atopic dermatitis is based on elimination measures and local anti-inflammatory therapy for skin exacerbations, but often such a complex is insufficient to relieve the symptoms of the disease, which leads to the need to use targeted therapy with monoclinal antibodies, including in some cases upadacitinib. Description of the clinical case. This publication presents our own successful experience of using upadacitinib in the form of a description of a clinical case in an 8-year-old patient with uncontrolled severe AtD. Before the drug was prescribed, the patient’s disease course was continuous, with severe exacerbations and no remission, as well as resistance to the recommended therapy at this age, including targeted therapy (Dupilumab, Omalizumab).Conclusion. In our opinion, the appointment of upadacitinib outside the age limits of the instructions may be justified in the most severe cases of atopic dermatitis, torpid to traditional therapy and other targeted drugs, since it carries fewer risks of side effects than the use of systemic glucocorticosteroids and cytostatics, but requires a consultation in an appropriate institution.

Disease characteristics, comorbidities, treatment patterns and quality of life impact in children <12 years old with atopic dermatitis: Interim results from the PEDISTAD Real-World Registry

In severe cases of atopic dermatitis (AD) systemic treatment is indicated. So far, cyclosporine and systemic glucocorticosteroids represented the only systemic treatment options approved for the indications of AD in Germany; however, from clinical practice there is increasing evidence for beneficial therapeutic effects in AD by other immunosuppressive or immunomodulatory substances, such as mycophenolate, methotrexate, alitretinoin and ustekinumab. Beyond this, ongoing research activities focus on abetter understanding of genetic and immunological aspects of this chronic inflammatory skin disease. Regarding treatment with mycophenolate, genetic polymorphisms in AD patients could be identified that might predict responsiveness to this medication. Moreover, several new substances specifically targeting inflammation in AD are currently being studied and the first promising treatment effects on skin condition and pruritic symptoms of AD could be observed. As an exceptional result of this development in September 2017 in Europe and therefore in Germany the first biologic as first-line treatment was approved for the indication of moderate to severe AD in adults. Dupilumab is ahuman monoclonal IgG4 antibody that blocks asubunit of the interleukin (IL)-4 and IL-13 receptors, thus inhibiting the proinflammatory effects of these cytokines. Furthermore, the cytokine IL-13 itself, the IL-31 receptor, which is of particular relevance for pruritus in AD, the histamine-4-receptor and Janus kinases represent further promising targets currently being investigated in clinical trials for the treatment of AD.

Lowgrade cutaneous inflammation, which persists after induction of remission of atopic dermatitis (AD), determines the risk of repeated relapses and progression of the disease. It has been well established that subclinical inflammation in the skin of atopic patients may be inhibited by topical corticosteroids (TCS) and topical calcineurin inhibitors (TCI), and proactive courses of these drugs prolong remission of the disease. In terms of prolonged application, TCI have some advantages over TCS in the context of safety. However, the routine use of TCI in AD is constrained by many practitioners who do not accept the concept of subclinical chronic inflammation and the strategy of maintenance antiinflammatory therapy on areas prone to repeated relapses, as well as obsolete myths about the association of TCI application with increased risk of cutaneous lymphoma. The review presents modem data on the pathophysiology of AD with a focus on subclinical skin inflammation, which persists after regression of acute manifestations of the disease, and the possibilities of suppressing this inflammation with TCI. Data on the safety of TCI for longterm use and the absence of prooncogenic potential are given. In addition, the relevance and expediency of pimecrolimus use in children under 2 years of age are emphasized.
