Brief summary
Intravenous immunoglobulin (IVIG) is used for treatment of a heterogeneous group of immune related disorders both as immune-replacement and immune-modulating therapy. Sanquin developed a 100 mg/ml IVIg product (Nanogam 100 mg/ml). Patient will receive one infusion with Nanogam 50 mg/ml as they used to (same dose) and subsequently 4 infusions with Nanogam 100 mg/ml (same dose). Aim is to show bioequivalency between the 50 mg/ml and the 100 mg/ml product of Sanquin.
Interventions
Blood samples are drawn before infusion with Nanogam 50 and Nanogam 100 mg/ml and IgG levels are determined to study PK
