| E.3 | Principal inclusion criteria  | 
- Age of at least 18 years. - Diagnosis of ITP according to standard criteria i.e. isolated thrombocytopenia with an otherwise normal peripheral blood smear (bone marrow examination optional), and absence of other causes of thrombocytopenia. - Platelet count of 20.000/µL or less with or without bleeding manifestations. - Freely given written informed consent from patient. - Women of reproductive age: negative result on a pregnancy test (HCG-based assay) and will practice contraception using a method of proven reliabilty for the duration of the study. | 
 
 
 | 
| E.4 | Principal exclusion criteria | 
- Chronic refractory ITP patients, defined as those who fail to respond to standard treatment (oral corticosteroids and intravenous immunglobulin and anti-D) or require unacceptably high doses of corticosteroids to maintain a safe platelet count. - Thrombocytopenia secondary to other diseases (such as AIDS) or drug-related thrombocytopenia. - Administration of IGIV, anti-D or other platelet enhancing drugs within 30 days before enrollment, except for long-term corticosteroid therapy in patients with chronic ITP when the dose has been stable during the preceding 30 days and no dosage increase is planned within 7 days after treatment. - Experimental treatment (eg Rituximab) within 3 months before enrollment. - Prophylactic preoperative treatment for elective splenectomy. - Live viral vaccination within the last month before study entry. - Emergency operation. - Severe liver or kidney disease (ALAT 5x > normal value, creatinine > 120 µmol/L). - History of hypersensitivity to blood or plasma derived products, or any component of the product, such as maltose. - Known IgA deficiency and antibodies against IgA. - History of, or suspected drug abuse. - Pregnant and nursing women. - Unable or unwilling to comply with the study protocol. - Participating in another clinical study currently or during the 3 months before study entry. |
