Klotsman M, Anderson WH, Wyatt D, Lewis T, Theus N, Santoro D. Treatment of moderate-to-severe canine atopic dermatitis with modified-release mycophenolate (OKV-1001): A pilot open-label, single-arm multicentric clinical trial. Vet Dermatol 2024. [PMID: 39129671 DOI: 10.1111/vde.13283] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2024] [Revised: 05/26/2024] [Accepted: 07/24/2024] [Indexed: 08/13/2024]
Abstract
BACKGROUND Mycophenolate is an immunomodulating agent successfully used for the treatment of moderate-to-severe atopic dermatitis (AD) in people. Mycophenolate is an effective steroid-sparing treatment option for use in dogs with inflammatory skin diseases. OBJECTIVE To evaluate whether once-daily modified-release mycophenolate (OKV-1001) is safe and effective for treating moderate-to-severe canine AD. ANIMALS Client-owned atopic dogs (n = 9) were enrolled. MATERIALS AND METHODS In an open-label multicentre pilot study, OKV-1001 (30 mg/kg every 24 h) was given orally for ≤84 days. Concomitant tapering doses of glucocorticoids were administered up to Day (D)28. Clinicians assessed Canine Atopic Dermatitis Extent and Severity Index, 4th iteration (CADESI-04) on D0, D14, D28, D56 and D84. Body weight and clinical pathological parameters were measured at baseline and at the end of the study. RESULTS Treatment with OKV-1001 combined with glucocorticoids significantly reduced the severity of AD within two weeks in seven of nine (77.8%) dogs. The mean percentage change from baseline in the CADESI-04 score was 29% (p = 0.009) at D14 (n = 9), 39% (p = 0.008) at D28 (n = 9) and 49% (p = 0.03) at D56 (n = 7) at which point glucocorticoids had been withdrawn. In two dogs the improvement in CADESI-04 was 62% and 23% (respectively) on D84. No significant adverse events including clinical pathological findings were reported. CONCLUSIONS AND CLINICAL RELEVANCE Modified-release mycophenolate (OKV-1001) may represent a promising alternative treatment option for dogs with moderate-to-severe AD. The safety and efficacy profile of OKV-1001 will need to be established in larger, placebo-controlled clinical trials.

Abstract
The treatment of atopic dermatitis (AD) with oral treatments has been limited in the past due to the increased risk of adverse effects associated with oral agents. However, in recent years, a shift toward the minimization of adverse effects has been explored. Although existing treatment options like oral corticosteroids and Immunosuppressive therapies have been utilized for acute flare-ups of AD, their long-term use is limited by adverse effects and the need for lab monitoring. New systemic treatment options such as Janus kinase (JAK) inhibitors are emerging as a promising therapy, due to their quick onset and antipruritic features. However, the black box warning associated with this medication class requires careful selection of appropriate candidates and patient education despite early favorable safety profiles seen in AD trials. Discussion of other oral agents, like antibiotics and antihistamines, and their role in AD management are also clarified.

Abstract
Recent advances in atopic dermatitis (AD) present the condition as a heterogeneous disease of distinct endotypes across ethnic groups. AD in people with skin of colour may appear psoriasiform, lichenoid, scaly or papular, with a violaceous colour and there is a higher prevalence of post-inflammatory dyspigmentation compared with affected individuals of White ethnicity. These differences in clinical presentation may limit the use of AD assessment tools in people with skin of colour, leading to the potential for misdiagnosis and underestimation of severity, particularly in relation to assessment of erythema. Recent targeted therapies for AD have been studied in multiple ethnic groups; however, ethnicity-based subgroup analysis is often not performed. Further research is required to understand whether treatment responses or safety may differ among ethnic groups.

Abstract
INTRODUCTION Atopic dermatitis (AD) is an inflammatory disease affecting over 20% of the pediatric population, with 85% of cases presenting before the age of five. Recently, therapeutic options in pediatric patients have evolved rapidly, following extensive development in adult treatments. AREAS COVERED This review will encompass relevant molecular drivers, along with an overlook on treatment modalities in pediatric AD, as well as a summary of pipeline treatments in clinical trials for pediatric patients from PubMed, Google Scholar, and Clinicaltrials.gov up to July 2022. Topical corticosteroids are the mainstay for AD flares in adults and children. Topical approved agents in pediatric AD are calcineurin inhibitors, crisaborolecrisaborole, and ruxolitinib. Dupilumab is the only FDA approved biologic for patients with AD from six months of age. A Janus kinase inhibitor, upadacitinib, is a systemic treatment approved for pediatric AD patients (age >12 years). Systemic immunosuppressants used in pediatric AD include methotrexate, azathioprine, cyclosporinecyclosporine, and mycophenolate mofetil. EXPERT OPINION Data regarding disease prevention are conflicting, however, an abundance of research has transpired regarding amelioration of symptoms and induction of disease clearance by targeting numerous pathological mechanisms. Understanding the pediatric AD phenotype will further advance the field and the development of improved therapeutics.

Abstract
Currently, there are a few detailed guidelines on the overall management of children and adolescents with moderate-severe atopic dermatitis. AD is a complex disease presenting with different clinical phenotypes, which require an individualized and multidisciplinary approach. Therefore, appropriate interaction between primary care pediatricians, pediatric allergists, and pediatric dermatologists is crucial to finding the best management strategy. In this manuscript, members of the Italian Society of Pediatric Allergology and Immunology (SIAIP), the Italian Society of Pediatric Dermatology (SIDerP), and the Italian Society of Pediatrics (SIP) with expertise in the management of moderate-severe atopic dermatitis have reviewed the latest scientific evidence in the field. This narrative review aims to define a pathway to appropriately managing children and adolescents with moderate-severe atopic dermatitis.

Abstract
INTRODUCTION While topical medications are the first line of treatment for mild-to-moderate atopic dermatitis, they are ineffective in individuals with diffuse disease and moderate-to-severe atopic itch. For these individuals, as well as those who do not respond to topical treatments, systemic medicines are typically essential and helpful. AREAS COVERED We conducted a review of the literature to identify established systemic therapies, novel biologic agents, and recent advances in the pathophysiology of atopic dermatitis. The review discusses these data, which show that the majority of atopic itch medications now in development target the type 2 immune axis and brain sensitization, two main etiologies of atopic itch. We emphasize the evidence, efficacy, and side effect profiles of currently available systemic medications for atopic itch, as well as future potential for tailored therapy. EXPERT OPINION We give our professional opinion on the current state of knowledge about atopic eczema pathogenesis and the innovative targets and therapies for atopic itch that include MRGPRX2, periostin, gabaergic medicines, and JAK/STAT inhibitors. Additionally, we discuss patient populations that stand to benefit the most from targeting these molecules or utilizing these drugs, as well as those who may face a disproportionate weight of adverse effects.

Abstract
INTRODUCTION Atopic dermatitis is a common dermatologic condition that affects millions of people worldwide, and a standardized approach to treatment was published by the American Academy of Dermatology (AAD) in 2013-14. Since 2014, new FDA-approved treatment options such as dupilumab and crisaborole have changed the landscape of AD management, and future therapies such as JAK inhibitors and anti-interleukin 13 and 31 antibodies appear effective, emphasizing the need for a comprehensive review to give clinicians an updated toolbox to aid in pharmacologic management. AREAS COVERED In this review, the authors explore the updated efficacy and safety data on established therapeutic options for AD including topical corticosteroids, topical calcineurin inhibitors, cyclosporine, azathioprine, methotrexate, and mycophenolate mofetil. In addition, the authors also explore trial data and studies on dupilumab, crisaborole, omalizumab, tofacitinib, ruxolinitib, abrocitinib, baricitinib, upadacitinib, delgocitinib, nemoliuzumab, and tralokinumab. EXPERT OPINION The AAD guidelines must be updated in the future to include several new treatment modalities that have revolutionized the pharmacologic management of patients with AD, including dupilumab and crisaborole. The future of AD treatment is also extremely bright, as JAK inhibitors and Il-13/31 antibodies have shown convincing results in the improvement of AD patients' lives in various trials and studies that have been examined in this paper.

Abstract
Pruritus is the most burdensome and prevalent symptom in patients suffering from atopic dermatitis. Treating atopic itch has historically been a challenge due to multiple underlying mechanisms within its pathogenesis and an incomplete understanding of them. In recent years, our understanding of these mechanisms have increased tremendously and subsequently, new treatments have reached the market that target the pathophysiology of atopic itch from different angles. In addition, there are several promising new treatments currently in development and trials. In the current article, we discuss these currently available treatment options, their available evidence and efficacy, and highlight some of the more recent advancements in the field.

Abstract
Atopic dermatitis (AD) is a common disease of childhood, and some patients experience a prolonged clinical course into adolescence and adulthood. Systemic management is required when AD is not adequately controlled with topical medications. Our aim is to provide a comprehensive review of commonly used systemic immunomodulating agents in childhood and adult AD, including cyclosporine A (CsA), azathioprine (AZA), methotrexate (MTX) and mycophenolate mofetil (MMF), which are prescribed off-label in the United States, as well as dupilumab, an FDA-approved biologic. We will also provide a brief overview of emerging systemic therapies currently under investigation.

Abstract
Mycophenolate mofetil is an established anti-proliferative and immune-suppressive agent that minimizes the proliferation of inflammatory cells by interfering with nucleic acid synthesis. Herein, we report our discovery of the prostaglandin inhibiting properties of MMF, which offers new applications for the drug in the treatment of inflammatory diseases. The estimated values of IC50MMFCOX-1, IC50MMFCOX-2, and IC50MMF5-LOX were 5.53, 0.19, and 4.47 µM, respectively. In contrast, mycophenolic acid (MPA) showed slightly stronger inhibition: IC50MPACOX-1, IC50MPACOX-2, and IC50MPA5-LOX were 4.62, 0.14, and 4.49 µM, respectively. These results indicate that MMF and MPA are, respectively, 28.6 and 33 times more selective for cyclooxygenase-2 than for cyclooxygenase-1, which implies that MMF would have less impact on the gastric mucosa than most nonselective, nonsteroidal anti-inflammatory drugs. Furthermore, MMF provided dose-dependent relief of acute inflammation in the carrageenan-induced rat paw edema test, with results comparable to those of celecoxib and indomethacin. Molecular dynamics simulations indicated that the MMF bond with COX-2 was stable, as evidenced by a low root-mean-square deviation of atomic positions, complementary per-residue root-mean-square fluctuation, and 0–4 hydrogen bonds during the 50-ns simulation time. Therefore, MMF provides immune-suppressing, cyclooxygenase-inhibiting, and inflammation-relieving properties. Our results indicate that MMF can be 1) repositioned for inflammation treatment without the need for further expensive clinical trials, 2) used for local acute inflammations, and 3) used as a sparing agent for other steroid and non-steroid anti-inflammatory medications, especially in topical applications.

Abstract
Atopic dermatitis (AD) is a common yet complex skin disease, posing a therapeutic challenge with increasingly recognized different phenotypes among variable patient populations. Because therapeutic response may vary on the basis of heterogeneous clinical and molecular phenotypes, a shift toward precision medicine approaches may improve AD management. Herein, we will consider biomarkers as potential instruments in the toolbox of precision medicine in AD and will review the process of biomarker development and validation, the opinion of AD experts on the use of biomarkers, types of biomarkers, encompassing biomarkers that may improve AD diagnosis, biomarkers reflecting disease severity, and those potentially predicting AD development, concomitant atopic diseases, or therapeutic response, and current practice of biomarkers in AD. We found that chemokine C-C motif ligand 17/thymus and activation-regulated chemokine, a chemoattractant of TH2 cells, has currently the greatest evidence for robust correlation with AD clinical severity, at both baseline and during therapy, by using the recommendations, assessment, development, and evaluation approach. Although the potential of biomarkers in AD is yet to be fully elucidated, due to the complexity of the disease, a comprehensive approach taking into account both clinical and reliable, AD-specific biomarker evaluations would further facilitate AD research and improve patient management.

Abstract
This guideline is an update from August 2020 the S2k-guideline "Atopic dermatitis" published in 2015. The reason for updating this chapter of the guideline were the current developments in the field of systemic therapy of atopic dermatitis. The agreed recommendations for systemic treatment in atopic dermatitis of the present guideline are based on current scientific data. Due to the approval of dupilumab for the treatment of moderate to severe atopic dermatitis, which cannot be treated sufficiently with topical drugs alone, this part of the guideline has now been adapted and newly consented. The indication for systemic therapy and the therapeutic response to topical and systemic treatment should be recorded and documented in a suitable form in clinic and practice. A standardized documentation of the indication for system therapy in atopic dermatitis can be recommended and is also part of the updated chapter of this guideline.

Abstract
Background: For severe cases of atopic dermatitis, systemic or potent agents may be required for control of disease. There have been some reports of treatment efficacy of off-label use of mycophenolate mofetil (MMF) in patients with refractory atopic dermatitis or have developed adverse effects to initial systemic agents.Methods: Electronic searches were performed using six databases from their inception to April 2019. Data were extracted and analyzed according to predefined clinical endpoints.Results: From 140 cases, the mean age was 38.21 ± 22.8 years. There were 52.9% males and 47.1% females. The average number of failed agents was 3.5 ± 1.2. 77.6% reported partial or full remission. Relapses occurred in 8.2% of cases. The average time for initial effects was 6.8 ± 7 weeks. There was a significant reduction in pre to post SCORAD scores by 18 points (p = .0002). More males had complications compared to females. Prolonged duration of treatment ≥1 year was associated with herpes infections.Conclusions: In summary, the current evidence to date is low-quality in nature but is promising regarding the efficacy and safety of MMF for adult and pediatric atopic dermatitis. There should be ongoing monitoring for infections that may develop on long term therapy.

Abstract
Atopic dermatitis (AD) is the most common itchy dermatosis that affects millions of children and adults worldwide. Chronic itch in this condition has significant impact on measures of quality of life, such as sleep. Treating itch in AD has been challenging for decades, but new drugs have emerged in the last year with significant anti-pruritic effect. The optimal treatment regimen for atopic itch addresses barrier dysfunction, inflammation, neural hypersensitivity, and the itch-scratch cycle. Topical moisturizers remain the foundation of treatment and should be used by all patients with AD-associated pruritus. Step-wise therapy, from topical anti-inflammatory creams to systemic monoclonal antibodies and immunosuppressants, is recommended. There are multiple adjuvant therapies that can be used, especially to target itch in the setting of minimal skin inflammation. Finally, patient education, sleep management, and stress relief are important components to optimize outcomes. This review assesses the latest advances and treatment recommendations for pruritus in AD. Finally, suggested therapeutic ladders and emerging treatments are discussed.

Abstract
BACKGROUND Patients with severe atopic dermatitis (AD) may require potent immunosuppressive therapy to control their disease. Mycophenolate mofetil (MMF) has been suggested as a safe and effective drug in these cases. OBJECTIVES To investigate effectiveness and tolerability of oral MMF in adult patients with severe recalcitrant AD. METHODS During the years 2010-2017 oral MMF 2-3 g/day was administered to adult patients with severe recalcitrant AD who failed other major systemic drugs, or where other drugs, including cyclosporine (CSA), methotrexate, and azathioprine, were contraindicated. RESULTS Of 9 consecutive adult patients, 4 (44%) responded completely, 2 (22%) had partial response, and 3 (33%) did not respond at all. The MMF therapy was continued for 5-36 months (average 21 months) without major side effects. CONCLUSIONS Oral MMF may be an effective drug in AD. Due to its good safety profile, it may be recommended as a first-line systemic therapy, or successive to CSA in the long term.

Abstract
The underlying pathology of atopic dermatitis (AD) includes impaired skin barrier function, susceptibility to Staphylococcus aureus skin infection, immune dysregulation, and cutaneous dysbiosis. Our recent investigation into the potential role of Gram-negative skin bacteria in AD revealed that isolates of one particular commensal, Roseomonas mucosa, collected from healthy volunteers (HVs) improved outcomes in mouse and cell culture models of AD. In contrast, isolates of R. mucosa from patients with AD worsened outcomes in these models. These preclinical results suggested that interventions targeting the microbiome could provide therapeutic benefit for patients with AD. As a first test of this hypothesis in humans, 10 adult and 5 pediatric patients were enrolled in an open-label phase I/II safety and activity trial (the Beginning Assessment of Cutaneous Treatment Efficacy for Roseomonas in Atopic Dermatitis trial; BACTERiAD I/II). Treatment with R. mucosa was associated with significant decreases in measures of disease severity, topical steroid requirement, and S. aureus burden. There were no adverse events or treatment complications. We additionally evaluated differentiating bacterial metabolites and topical exposures that may contribute to the skin dysbiosis associated with AD and/or influence future microbiome-based treatments. These early results support continued evaluation of R. mucosa therapy with a placebo-controlled trial.

Abstract
Therapy of severe atopic dermatitis, which is refractory to consistent treatment with topical steroids and topical calcineurin inhibitors is still a problem in many cases. The use of cyclosporine, which is the only approved systemic drug for the therapy of severe atopic dermatitis, is often limited by contraindications or adverse reactions. In this context, results from controlled and open-label studies with novel therapeutic approaches such as methotrexate, omalizumab or rituximab, which are in part very promising, are of great interest. In this work we would like to provide an overview of established and new therapeutic options for the treatment of severe atopic dermatitis.

Abstract
Itch, or pruritus, is a hallmark feature of atopic dermatitis (AD). The impact of AD-related pruritus can range from mildly distressing or distracting to completely disabling. Traditionally, management of itch in AD patients has focused on restoring the altered skin barrier with topical emollients and/or reducing inflammation. A growing emphasis has been placed on directly targeting the neural transmission pathways that mediate itch signaling. Off-label use of neuromodulatory agents has helped reduce this aggravating symptom in atopic patients. This article reviews the current literature on the use of neuromodulatory agents and nonpharmacologic alternative therapies used to treat AD-related pruritus.

Abstract
Mycophenolate mofetil (MMF) is an immunosuppressive drug the efficiency of which has been established in renal transplantation. Recent studies suggest that it may also be effective in the treatment of variant skin diseases especially if the skin lesions are triggered by lymphocytes. Studies have shown efficacy in autoimmune bullous dermatoses, atopic dermatitis and psoriasis. However, there are no placebo-controlled trials that support the use of MMF as first line therapy in these skin diseases.

Abstract
Immunosuppressive treatment has shown to be effective in various ocular inflammatory disorders. Factors limiting their use are the individual response and the rate of side effects. This report summarizes our knowledge about the use of mycophenolate mofetil (MMF) in the treatment of ocular cicatricial pemphigoid (OCP), uveitis, atopic keratoconjunctivitis (AKC), prevention of graft rejection after penetrating keratoplasty (PK) and scleritis. Controlled studies have been performed for prevention of graft rejection after PK, showing MMF as effective in the prevention of graft rejection as cyclosporine A. In experimental uveitis, MMF has been demonstrated to be highly effective in prevention of retinal destruction. A number of studies have now shown that MMF also seems effective in uveitis. There are also studies with smaller patient groups which point out the effectiveness of MMF in OCP, AKC, and scleritis. In most of the studies, the spectrum of side effects was small, compared to other immunosuppressives.

Abstract
Mycophenolic acid (MPA) is an active metabolite of mycophenolate mofetil, a new immunosuppressive drug effective in the treatment of canine autoimmune diseases. The impact of MPA on immunity is ambiguous and its influence on the canine immune system is unknown. The aim of the study was to determine markers of changes in stimulated peripheral canine lymphocytes after treatment with MPA in vitro. Twenty nine healthy dogs were studied. Phenotypic and functional analysis of lymphocytes was performed on peripheral blood mononuclear cells cultured with mitogens and different MPA concentrations– 1 μM (10−3 mol/m3), 10 μM or 100 μM. Apoptotic cells were detected by Annexin V and 7-aminoactinomycin D (7-AAD). The expression of antigens (CD3, CD4, CD8, CD21, CD25, forkhead box P3 [FoxP3] and proliferating cell nuclear antigen [PCNA]) was assessed with monoclonal antibodies. The proliferation indices were analyzed in carboxyfluorescein diacetate succinimidyl ester (CFSE)-labeled cells. All analyses were performed using flow cytometry. The influence of MPA on apoptosis was dependent on the mechanism of cell activation and MPA concentration. MPA caused a decrease in the expression of lymphocyte surface antigens, CD3, CD8 and CD25. Its impact on the expression of CD4 and CD21 was negligible. Its negative influence on the expression of FoxP3 was dependent on cell stimulation. MPA inhibited lymphocyte proliferation. In conclusion, MPA inhibited the activity of stimulated canine lymphocytes by blocking lymphocyte activation and proliferation. The influence of MPA on the development of immune tolerance–expansion of Treg cells and lymphocyte apoptosis–was ambiguous and was dependent on the mechanism of cellular activation. The concentration that MPA reaches in the blood may lead to inhibition of the functions of the canine immune system. The applied panel of markers can be used for evaluation of the effects of immunosuppressive compounds in the dog.

Abstract
The guidelines aim to provide advice on the management of hand eczema (HE), using an evidence- and consensus-based approach. The guidelines consider a systematic Cochrane review on interventions for HE, which is based on a systematic search of the published literature (including hand-searching). In addition to the evidence- and consensus-based recommendation on the treatment of HE, the guidelines cover mainly consensus-based diagnostic aspects and preventive measures (primary and secondary prevention). Treatment recommendations include non-pharmacological interventions, topical, physical and systemic treatments. Topical corticosteroids are recommended as first line treatment in the management of HE, however continuous long-term treatment beyond six weeks only when necessary and under careful me-dical supervision. Alitretinoin is recommended as a second line treatment (relative to topical corticosteroids) for patients with severe chronic HE. Randomized control trials (RCT) are missing for other used systemic treatments and comparison of systemic drugs in “head-to-head” RCTs are needed.The guidelines development group is a working group of the European Society of Contact Dermatitis (ESCD) and has carefully tried to reconcile opposite views, define current optimal practice and provide specific recommendations, and meetings have been chaired by a professional moderator of the AWMF (Arbeitsgemeinschaft der Wis-senschaftlichen Medizinischen Fachgesellschaften; Association of the Scientific Medi-cal Societies in Germany).No financial support was given by any medical company. The guidelines are expected to be valid until December 2017 at the latest.

Abstract
There is a strong current trend for using complementary and alternative medications to treat atopic dermatitis. Atopic dermatitis is a common, chronic, pruritic, and inflammatory skin disease. It can have a profound, negative effect on patients' quality of life. Mild cases of atopic dermatitis can be controlled by the application of moisturizers and topical corticosteroids. However, in severe cases, application of immunosuppressive medication is unavoidable but it can have adverse effects. In traditional Persian medicine, diseases similar to resistant atopic dermatitis are treated with whey in combination with decoction of field dodder. Both whey and field dodder have anti-inflammatory properties. Consumption of whey can also aid skin repair, mitigate pruritus, and help combat the high level of stress experienced by patients. Therefore, it is hypothesized that consumption of traditional medicinal treatment of whey with decoction of field dodder can be applied as a complementary treatment for atopic dermatitis.

Abstract
Itch is a common distressing symptom which may be caused by multifactorial aetiologies including inflammatory skin diseases, systemic diseases, neuropathic conditions and psychogenic disorders. Itch is a term used synonymously with pruritus and is defined as acute if it lasts less than 6 weeks or chronic if it persists for more than 6 weeks. It can have the same impact on the quality of life as chronic pain and shares many of the same pathophysiological pathways. Depending on the aetiology of the itch, different pathogenic mechanisms have been postulated with a number of mediators identified. These include histamine, leukotrienes, proteases, neuropeptides, cytokines and opioids, which may activate peripheral itch-mediating C-fibres via receptors on the nerve terminals and central neuronal pathways. Therefore, there is no single universally effective anti-itch treatment available. First-line treatments for itch include topical therapies, such as emollients, mild cleansers (low pH), topical anaesthetics, steroids, calcineurin inhibitors and coolants (menthol). Treatment with systemic therapies can vary according to the aetiology of the chronic itch. Non-sedating antihistamines are helpful in conditions such as urticaria where the itch is primarily histamine mediated. Although the itch of eczema is not mediated by histamine, sedating antihistamines at night are helpful to break the itch-scratch cycle. Chronic itch may also be treated with other systemic therapies, such as anticonvulsants, antidepressants as well as mu-opioid antagonists, kappa-opioid agonists and phototherapy, depending on the cause of the itch. This article summarises the topical and systemic therapies available with our current understanding of the pathophysiology of itch.

Abstract
We report two cases of adults with urticarial dermatitis who could not be managed by a variety of treatments but who obtained good control with mycophenolate mofetil (MMF). A clinical response was seen 6-8 weeks from treatment onset and they were maintained on MMF 1 g twice daily (case 1), and MMF 1 g omni mane and 500 mg omni nocte (case 2), with no major exacerbations for many years. MMF is an immunosuppressive agent, which is currently used off-label for many dermatological conditions. To date, there have been no studies investigating the use of MMF as a treatment for urticarial dermatitis. The cases we present suggest that MMF is an effective treatment for this condition, and we recommend that MMF be considered as a treatment option.

Abstract
Systemic therapy for atopic dermatitis (AD) is indicated in patients with severe disease refractory to adequate topical treatment. Currently available drugs aim to decrease inflammation by suppressing and/or modulating immune responses and thus may indirectly improve skin barrier function, resulting in a decrease in clinical signs and symptoms in particular pruritus. Before considering systemic treatment, patient adherence to topical treatment including skin care has to be ensured. The selection of the drug depends on the disease severity, localization, complications, concomitant diseases, and age of the patient, but also on their availability and costs as well as the doctor's experience. Bearing in mind the potential risk of resistance, systemic therapy with antibiotics should be exclusively considered in clinically manifest infections such as in children. Here, we review recently published clinical trials and case reports on systemic therapy of pediatric and adult patients with AD to draw conclusions for clinical practice. Although AD is a common disease, controlled clinical studies investigating the efficacy of systemic drugs are scarce, except for cyclosporine, which has been approved for the therapy of severe AD.

Abstract
OBJECTIVE To evaluate if eczema severity is associated with blood levels of immunoglobulins, white cell differentials and complements. METHODS White cell differentials, levels of serum immunoglobulins and complements of patients with eczema and miscellaneous non-eczema skin diseases were measured. Eczema severity and quality of life were assessed by SCORAD, Nottingham Eczema Severity Score (NESS) and Children's Dermatology Life Quality Index (CDLQI). Correlations were analyzed by Pearson's correlation test for parametric data and Spearman's rho correlation test for non-parametric data. RESULTS Serum IgE and peripheral blood eosinophil percentage were significantly higher in patients with eczema than other non-eczema skin diseases. Levels of IgE (log-transformed), IgA and IgG correlated with objective SCORAD (r = 0.52, 0.40, 0.29, respectively). Levels of eosinophil, neutrophils, lymphocytes and complements also correlated with objective SCORAD, with the eosinohil/lymphocyte ratio showing the highest correlation (r = 0.60, p < 0.01). Ratios of IgE/IgA, IgE/IgG, eosinophils/lymphocytes, eosinophils/neutrophils correlated positively with CDLQI. IgM appeared to have no correlation with eczema. CONCLUSIONS Blood levels of IgE, IgA, IgG,eosinophils, lymphocytes, neutrophils and complements pathophysiologically correlate with eczema severity. Eosinophil/lymphocyte ratio may represent a readily-available objective laboratory correlate of eczema severity. Eczema is a complex atopic disease involving many cellular and humoral components of the immune system.

Abstract
Atopic dermatitis (AD) is a relatively common disease in patients in the Asia-Pacific region. It presents a particular clinical challenge and requires careful clinical management. The chronic nature of AD characterized by flares, exacerbations and periods of quiescence requires a multipronged approach aimed at reducing itch, inflammation and the appearance of secondary lesions. In addition, varying levels of maintenance therapy may be required to avoid exacerbations. Survey data from the region indicate that there is significant variation across the Asia-Pacific with regard to current treatment practices. The management of AD may also be influenced by differing health-care systems, variable climate, access to medical care and cultural diversity. The current consensus guidelines have been developed to provide up-to-date and concise evidence- and experience-based recommendations directed towards general practitioners and general dermatologists in the Asia-Pacific region on the management of pediatric and adult AD.

Abstract
Atopic dermatitis, commonly known as eczema, is a common chronic, relapsing skin disease characterized by pruritus, disrupted epidermal barrier function, and immunoglobulin E-mediated sensitization to food and environmental allergens. Atopic dermatitis is a complex disease that arises from interactions between genes and the environment. Loci on several chromosomes have been identified, including a family of epithelium-related genes called the epidermal differentiation complex on chromosome 1q21. Mutations in filaggrin, a key protein in epidermal differentiation, have also been identified in early-onset and severe atopic dermatitis. There are 3 classical stages of eczema: infantile, childhood, and adulthood. The spectrum of eczema presentation varies widely from a variant that only affect the hand to major forms where a patient presents with erythroderma. The acute and subacute lesions of atopic dermatitis are often characterized by intensely pruritic, erythematous papules and vesicles with excoriations and a serous exudate. Chronic atopic dermatitis is exemplified by lichenified plaques and papules with excoriations. Atopic dermatitis patients are also at higher risk for skin infections, including bacterial and viral superinfections. Conventional therapy includes avoidance of irritants and potential allergens, as well as continued hydration of the skin with thick emollients. Topical corticosteroids and topical immunomodulators are often used primarily. Other therapies including phototherapy, antimicrobials, antihistamines, and systemic immunosuppressives are also options in certain situations.

Abstract
BACKGROUND Cyclosporin A (CsA) is frequently used in the treatment of severe atopic dermatitis (AD). Enteric-coated mycophenolate sodium (EC-MPS) may be an alternative with equal efficacy and fewer side effects. OBJECTIVE The aim of this observer-blinded randomized controlled trial was to compare EC-MPS with CsA as long-term treatment in adult patients with severe AD. METHODS Fifty five patients with AD were treated with CsA (5 mg/kg) in a 6-week run-in period. Thereafter, patients either received CsA (3 mg/kg; n = 26) or EC-MPS (1440 mg; n = 24) during a maintenance phase of 30 weeks and there was a 12-week follow-up period. Disease activity was measured using the objective SCORAD and serum thymus and activation-regulated chemokine (TARC) levels and side effects were registered. RESULTS During the first 10 weeks the objective SCORAD and serum TARC levels in the EC-MPS study arm were higher in comparison with the CsA study arm. In addition, 7 of the 24 patients treated with EC-MPS required short oral corticosteroid courses. During maintenance phase disease activity was comparable in both study arms. Side effects in both study arms were mild and transient. After study medication withdrawal, disease activity of the patients in the CsA study arm significantly increased compared with the EC-MPS study arm. LIMITATION The nonblinding of patients and prescriber of rescue medication are limitations. CONCLUSIONS This study shows that EC-MPS is as effective as CsA as maintenance therapy in patients with AD. However, clinical improvement with EC-MPS is delayed in comparison with CsA. Clinical remission after stopping EC-MPS lasts longer compared with CsA.
