To assess whether the immune derangement previously observed in SAPHO syndrome could be linked to variations in blood TH1, TH2 or TH17 lymphocytes frequency. Seven SAPHO patients with a protracted course of the disease were studied ex-vivo for intracellular cytokines production by means of flow-cytometry and compared with matched groups of Psoriatic(More)
INTRODUCTION Hereditary angioedema due to C1-inhibitor deficiency (C1-INH-HAE type I) or dysfunction (C1-INH-HAE type II) is a rare disease characterized by recurrent episodes of edema with an estimated frequency of 1:50,000 in the global population without racial or gender differences. In this study we present the results of a nationwide survey of(More)
Sporadic and familiar forms of non-histaminergic angioedema and normal C1 inhibitor encompass a group of disorders possibly caused by bradikinin. We aimed to study the subgroups of hereditary angioedema with FXII mutation (FXII-HAE), unknown genetic defect (U-HAE) and idiopathic non-histaminergic acquired angioedema (InH-AAE). We screened the F12 locus in(More)
Refractory or recurrent infections of skin, nails, and the mucous membranes are clinical signs of chronic mucocutaneous candidiasis, frequently associated with immunological defects. Here we describe a 39-years-old female patient, with familial CMC, that presented with an extensive infection caused by an azole-resistant Candida albicans isolate,(More)
Synovitis, Acne, Pustulosis, Hyperostosis and Osteitis (SAPHO) syndrome is a rare and often unrecognized disease with prominent inflammatory cutaneous and articular manifestations. Since the identification of the syndrome many immunosuppressive drugs have been used for the management of SAPHO, with variable results. The use of anti- TNF-α agents as a(More)
Hereditary angioedema (HAE) due to C1 inhibitor (C1-INH) deficiency is an autosomal dominant disorder caused by mutations in SERPING1 gene. More than 200 different mutations are known, with high genetic heterogeneity and high frequency of private familial mutations. We analyzed for genetic mutations the C1-INH locus in 11 Sardinian families, revealing in(More)

ISSN 0001-5555 Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis of unknown aetiology, characterized by primarily sterile, painful ulcers with typical violaceous undermined borders and mucopurulent or haemorrhagic exudate. PG is commonly(More)
BACKGROUND Hereditary angioedema (HAE) is a rare genetic disease usually caused by mutation in the C1 inhibitor or the coagulation Factor XII gene. However, in a series of patients with HAE, no causative variants have been described, and the pathophysiology of the disease remains unknown (hereditary angioedema with yet unknown genetic defect [U-HAE]).(More)
Icatibant, an antagonist of the bradykinin B2 receptor, was approved for the treatment of acute attacks of hereditary angioedema in the EU in 2008. This paper presents the case of a 65-year-old woman affected by frequent acute attacks of hereditary angioedema who benefitted from a change of therapy to icatibant, following years of treatment with(More)
