Potential Indications of Dupilumab in Th-2 Inflammatory Disease.

Dupilumab is a fully humanized IgG4 monoclonal antibody, inhibiting IL-4 and IL-13 signaling, which are the main cytokines involved in type 2 inflammatory diseases. Its introduction was a breakthrough in the treatment of moderate-to-severe atopic dermatitis, but it is also used in other inflammatory diseases, including asthma, eosinophilic esophagitis and chronic rhinosinusitis with nasal polyposis. Recent advances in the understanding of inflammatory pathways have revealed that Th2-type inflammation is involved in a wider range of diseases than previously thought. The aim of our review is to examine off-label therapeutic indications of dupilumab, including bullous dermatoses (pemphigus, bullous pemphigoid) and alopecia areata, and to investigate its potential applications in cancer patients on anti-PD1 therapy.

The Role of the Western Diet on Atopic Dermatitis: Our Experience and Review of the Current Literature.

The correlation between health and diet has always been a subject of interest in the field of dermatology and medicine in general. However, studies in the literature are still scarce, and need further investigation in the field of inflammatory skin diseases. In this paper, we report a case of a patient with atopic dermatitis whose complete recovery occurred only after combining dupilumab therapy with a Mediterranean diet regimen.

Management of psoriatic patients in biologic treatment associated with infectious comorbidities.

INTRODUCTION: Psoriasis is a chronic inflammatory disease affecting about 2% of population, involving both acquired and innate immunity. Psoriasis affects mainly skin, presenting multiple co-morbidities; among them infective ones. Re-activation of tuberculosis or viral hepatitis (HBV and HCV) still represents a therapeutic challenge in patients receiving treatment with biological drugs, as well as HIV infection. For this reason, a multidisciplinary approach with global treatment resulting from active collaboration of different specialists is highly recommended. AIM: To investigate the most common infective diseases as co-morbidities associated with psoriasis and to provide algorithms for screening, follow-up and therapeutic management in psoriatic patients. MATERIAL AND METHODS: We examined the main infectious comorbidities that can affect moderate to severe psoriatic patients, influencing the therapeutic choice as during the biological treatment both viral and tuberculosis re-activation may occur. We have therefore evaluated the main diseases (TB, Hepatitis B and C, HIV) and the monitoring of patients during treatment with biological agents. RESULTS: Regular monitoring of psoriatic patients is recommended during long-term treatment with biological drugs in order to identify cases of re-activation of the latent infective agent or de novo acquired infection. CONCLUSIONS: Here we report the state of art regarding management of psoriatic patients with these co-morbidities suggesting a specific screening and management for infectious diseases in patients with moderate to severe plaque psoriasis.
