RT info:eu-repo/semantics/article T1 Severe cutaneous vasculitis following intravenous infusion of gammagloubin in a patient with type II mixed cyroglobulinemia A1 Barrios del Pino, Yvelise A1 Yebra, Miguel A1 Rincón, José A1 Sanjuan, Isabel A1 Díaz-Espada, Fernando K1 Intravenous immunoglobulins, K1 Cryoglobulins AB Intravenous infusion of gammaglobulins (IVIG) is one of the treatments of choice in patients with type II mixed cryoglobulinemia (MC). We describe the case of a patient with MC who suffered an adverse generalised reaction with severe cutaneous vasculitis accompanied by a sudden increase in cryocrit levels shortly after being treated with IVIG. When the same gammaglobulin preparation was added in vitro to a sample of the patient's serum, a strong increment in cryoglobulin precipitation and depletion of the monoclonal IgM peak resulted. We suggest that this simple method of studying the displacement of the precipitation reaction could help to predict the outcome of treatment and must be performed before starting IVIG in patients with MC.
