    Abstract Porokeratosis represents a heterogeneous group of disorders characterized clinically by a distinctive ridge-like border and histologically by cornoid lamellae. A verrucous variant of porokeratosis involving the gluteal cleft has been recently described. We present 5 new cases and review the current literature to highlight the clinical and histopathologic features of this disorder. Descriptive terms including hyperkeratotic porokeratosis, genitogluteal porokeratosis, porokeratoma, follicular porokeratosis, and porokeratosis ptychotropica have all been used to describe this verrucous variant of porokeratosis involving the gluteal cleft. To avoid further confusion, we propose a consolidation of terminologies and suggest verrucous porokeratosis be added to the commonly described variants of porokeratosis.

    Abstract Atopic dermatitis (AD) is a chronic inflammatory skin disease associated with cutaneous hyperreactivity to environmental stimuli, resulting in increased infiltration of inflammatory cells, IgE production and enhanced expression of costimulatory molecules, cytokines and chemokines. CD30, a TNF receptor superfamily member, is a costimulatory molecule expressed on activated T and B cells. A positive correlation between soluble CD30 (sCD30) levels in patient serum and AD disease severity has been described previously. However, the relative frequencies and identities of cells expressing CD30 in AD patients and the relationship between the frequency of CD30 positive cells and serum sCD30 levels with disease severity remained unknown. To address these questions, immunofluorescence analysis of AD skin lesions representing different disease stages, was conducted. In addition to the CD4+ T cells, CD1a+ Langerhans cells and CD8+ T cells were found to express CD30 in AD lesions and the cell numbers correlated with disease severity. FACS analysis of AD patient blood samples revealed expression of CD30 on memory T-cells and a correlation with disease severity was identified. Finally, serum analysis of soluble mediators revealed positive correlations between sCD30, IgE, MDC, TARC and PARC levels with disease severity. Combined, our data provide correlative evidence that CD30+ cells, including Langerhans cells and CD8+ T-cells, may contribute to AD disease severity and that therapeutic strategies targeting CD30+ cells may provide benefit to AD patients.

    Abstract Atopic dermatitis (AD) is a chronic inflammatory skin disease associated with cutaneous hyperreactivity to environmental stimuli, resulting in increased infiltration of inflammatory cells, IgE production and enhanced expression of various co-stimulatory molecules, Th2 cytokines and chemokines. Antigen presenting cells (APCs) are critical for AD disease pathogenesis and interaction between APCs and inflammatory T cells represents an important signal required for induction and maintenance of the inflammatory process. CD40 was shown to be upregulated on inflammatory cells in patients with atopic dermatitis; however the identity of these cells and their correlation with disease severity remained unknown. To address these questions, we determined CD40 expression in skin lesions and on peripheral blood cells from AD patients and identified a positive correlation between the numbers of CD40 positive cells and disease severity. Furthermore, we identified the nature of CD40 positive cells in skin lesions to include CD1a+ and CD11b+ APCs. Finally, a correlation between serum PARC and IgE levels and the numbers of CD40+ cells in AD skin lesions was found. Combined, these findings demonstrate that CD40 is upregulated on APCs, cell types previously shown to contribute to AD disease pathology, and suggest that therapeutic strategies targeting CD40 positive cells may provide benefit to AD patients.

    Abstract Background: Severe atopic dermatitis (AD) often cannot be adequately controlled with topical agents. The continuous use of current systemic therapies for AD is limited by end-organ toxicities. A safe and effective systemic therapy for patients with recalcitrant AD is greatly needed.
    Objective: To evaluate the potential safety and efficacy of efalizumab, an inhibitor of T cell activation and migration, in adults with severe AD.
    Methods: An investigator-initiated, prospective, open-label, pilot study was conducted involving ten subjects with severe AD. Subjects received an initial conditioning subcutaneous dose of efalizumab of 0.7 mg/kg followed by 1.0 mg/kg weekly for another 11 weeks for a total of 12 doses. The primary efficacy outcome was the change in the mean Eczema Area and Severity Index (EASI) score from baseline as measured at week 12. Monitoring of adverse events continued for 8 weeks after discontinuation of therapy.
    Results: EASI scores improved from a mean baseline score of 37.1 +/- 13.5 to 17.6 +/- 14.5 at week 12 (52.3% improvement; P < .0001). Six out of ten subjects reached at least a 50% improvement in EASI score by week 12. Pruritus levels decreased from 6.9 cm +/- 1.8 cm to 4.9 cm +/- 2.5 cm utilizing a visual analogue score (P < .015). Overall, efalizumab was well tolerated. There were three significant adverse events during the course of this study, including thrombocytopenia, viral gastroenteritis, and a subject with worsening of disease beyond baseline levels after drug discontinuation.
    Limitations: It is difficult to apply these findings to larger populations of patients with AD because this study lacked a control group and involved a small number of subjects with very severe disease. Long-term efficacy and safety of efalizumab in this population is not known.
    Conclusions: Efalizumab therapy resulted in significant clinical improvements in six of ten subjects with severe AD. Efalizumab may serve as a good alternative to current systemic immunosuppressants used for AD; however, double-blind placebo-controlled studies are needed to test its efficacy and safety.

    Abstract Efalizumab is an mAb directed against CD11a, a molecule involved in T-cell activation and extravasation from blood into tissue. Ten patients with severe atopic dermatitis were treated with efalizumab for 84 days, and peripheral blood mononuclear cells were analyzed for expression of activation and adhesion markers. Efalizumab treatment led to decreases in CD11a mean fluorescence intensity (MFI) on naive, central memory, and effector memory CD4+ and CD8+ T cell subsets. MFI for CD18 was decreased in both CD4+ and CD8+ T cells. Percentages of cells positive for cutaneous lymphocyte antigen (CLA) were increased fourfold in all CD4+ and CD8+ T cell subsets. Increases in the percentages of CD4+ and CD8+ T cells expressing beta7 and CD49d were also observed. No significant changes were observed in the percentages of CD4+ and CD8+ T cells that produced either IFN-gamma or IL-4. In summary, efalizumab treatment resulted in (i) decreases in CD11a and CD18 expression in all circulating T-cell subsets and (ii) increases in the percentages of blood T cells expressing tissue homing markers (CLA, beta7, CD49d). These data suggest that blockade of T-cell extravasation into tissue is the major pathway by which efalizumab leads to improvement in cutaneous inflammation.
