"A number of case reports and pilot studies have been published recently, however representative, randomized, placebo controlled studies evaluating the efficacy and safety of biologicals in AD are still not available. Approaches resulting in reduced T cell activation using agents such as alefacept (fusion protein of lymphocyte function antigen (LFA)-3 (CD58) and immunoglobulin (Ig)G, rituximab (anti-CD20 antibody) and efalizumab (anti-CD11a antibody, no longer available) have been shown to be effective in selected patients with moderate to severe AD and were mentioned in guidelines [2,41-44].

[Show abstract][Hide abstract] ABSTRACT: Difficult to control atopic dermatitis (AD) presents a therapeutic challenge and often requires combinations of topical and systemic treatment. Anti-inflammatory treatment of severe AD most commonly includes topical glucocorticosteroids and topical calcineurin antagonists used for exacerbation management and more recently for proactive therapy in selected cases. Topical corticosteroids remain the mainstay of therapy, the topical calcineurin inhibitors tacrolimus and pimecrolimus are preferred in certain locations. Systemic anti-inflammatory treatment is an option for severe refractory cases. Microbial colonization and superinfection contribute to disease exacerbation and thus justify additional antimicrobial / antiseptic treatment. Systemic antihistamines (H1) may relieve pruritus but do not have sufficient effect on eczema. Adjuvant therapy includes UV irradiation preferably of UVA1 wavelength. “Eczema school” educational programs have been proven to be helpful.

[Show abstract][Hide abstract] ABSTRACT: Recent insights into the relevance of the epidermal barrier function and its interaction with components of the innate and adaptive immune responses in patients with atopic dermatitis (AD) give rise to a number of novel potential treatment options. In particular, the identification of loss-of-function mutations in the barrier protein filaggrin and of a diminished expression of certain antimicrobial peptides in AD skin stimulates new concepts to think beyond the T(H)1/T(H)2 paradigm. This review will focus on these most recent discoveries and will discuss new and corresponding proof-of-concept trials in patients with AD. It will further speculate on novel ways to restore the homeostasis among the 3 major components in AD skin suspected to be clinically relevant.

[Show abstract][Hide abstract] ABSTRACT: This review highlights some of the research advances in anaphylaxis, and hypersensitivity reactions to foods, drugs, and insects and in allergic skin disease that were reported in the Journal in 2008. Key epidemiologic observations include a rise in anaphylaxis in a population-based study and lower rates of peanut allergy in Israel, where infants consume peanut early compared with the United Kingdom, where dietary introduction is generally delayed. Advances in food allergy diagnosis include IgE epitope mapping that discloses the likelihood and severity of allergy; studies correlating likelihood of clinical reactivity on the basis of food-specific IgE to sesame, peanut, milk, and tree nuts; and an observation that a low baseline angiotensin-converting enzyme level may be associated with having pharyngeal edema during a reaction. Molecular, immunologic, and genetic studies are discerning pathways that are key in development of food allergy, identifying new modalities to interrupt mast cell degranulation, and elucidating risks associated with penicillin allergy. Regarding treatment, clinical studies show a majority of children with milk and egg allergy tolerate these proteins in modest amounts when they are extensively heated in baked goods, and studies show promise for oral immunotherapy to treat milk allergy and sublingual immunotherapy for honey bee venom hypersensitivity. The importance of skin barrier dysfunction has continued to be highlighted in the pathophysiology of atopic dermatitis (AD). Research has also continued to identify immunologic defects that contribute to the propensity of patients with AD to develop viral and bacterial infection. New therapeutic approaches to AD, urticaria, and angioedema have been reported including use of probiotics, biologics, vitamin D, and skin barrier creams.
