Molecular characterization of a fungal cyclophilin allergen Rhi o 2 and elucidation of antigenic determinants responsible for IgE-cross-reactivity.

Cyclophilins are structurally conserved pan-allergens showing extensive cross-reactivity. So far, no precise information on cross-reactive IgE-epitopes of cyclophilins is available. Here, an 18-kDa IgE-reactive cyclophilin (Rhi o 2) was purified from , an indoor mold causing allergic sensitization.

Anti-Neutrophil Cytoplasmic Antibody (ANCA)-Negative Small Vessel Vasculitis: A Rare Cause of Pulmonary Renal Syndrome.

Pulmonary renal syndrome (PRS) is characterized by both diffuse alveolar haemorrhage and glomerulonephritis as pathological features. Several immunologic and non-immunologic mechanisms including anti-neutrophil cytoplasmic antibody (ANCA)-positive vasculitis, anti-glomerular basement membrane disease, and systemic lupus erythematosus are commonly involved in the pathogenesis of the syndrome. We herein present a 60-year-old woman, non-smoker, who presented with fever, polyarthralgia, and the spreading of generalized purpuric rashes.
