Atopic dermatitis (AD) is a chronic inflammatory skin disorder characterized by eczematous skin lesions, pruritus and typical histopathological features. T cells are thought to play a key role, but B cells might also participate in the pathogenesis of AD. In two investigator-initiated pilot studies, we studied the effects of B cell depletion by monoclonal anti-CD20 antibody therapy or a reduction of activated T cells by LFA3-IgG fusion protein on moderate-to-severe AD. All patients treated with either rituximab or alefacept showed an improvement of their skin symptoms with a sustained effect after treatment. In both studies, histological alterations, such as spongiosis, acanthosis and dermal infiltrate, including T and B cell numbers, dramatically improved and the expression of IL-5 and IL-13 was reduced after therapy. Upon rituximab therapy, allergen-specific IgE levels were not altered and total serum IgE levels only slightly decreased. According to recent studies, neutralizing B and T cells products such as IgE or IL-5 might be effective in subgroups of patients with AD.
