Essential Thrombocythemia (ET)

ET is a rare myeloproliferative disorder with an increased incidence of thromboembolic and hemorrhagic complications. In order to understand the pathophysiological mechanisms of hemostatic complications we investigate the role of the endogenous thrombin potential in ET in comparison with healthy controls (Project leader: C. Langer).


Pregnancy in patients with Ph-negative chronic myeloproliferative disorders
Within the WP 9.11 of the European Leukemia Net (ELN-Registry of pregnancies in CMPDs) we set up a registry of pregnancies in CMPDs. It is planed to offer clinicians facing such situations the opportunity to register these rare cases via a standardized questionnaire. We therefore developed such a questionnaire and a database to set up a European registry. For ethical and legal reasons a proposal is currently presented to the commission of ethical affairs of the University of Ulm (Project leader: ).

Vascular complications of conception and pregnancy
Efficacy and safety of prophylactic anticoagulation with low-molecular weight (LMW) heparin during pregnancies at an increased vascular risk is evaluated. In a prospective matched pair study, reasons for idiopathic implantation failure are investigated. Serial assessments of platelet activation, microparticle generation and thrombin generation are used. Elucidating the etiology of implantation failure may help to generate a therapeutic approach.

Congenital and acquired Hemophilia
Within the hemophilia center we take care of about 50 patients with severe hemophilia A and B. We take part in clinical trials evaluating the efficacy and safety of several factor VIII and factor IX concentrates (Project leader: M. Sparber-Sauer).
Acquired hemophilia is a rare, yet catastrophic event. The role of a combined factor replacement and immunosuppressive therapy has been evaluated. Currently, the role of Rituximab, a monoclonal CD 20 antibody, for the treatment of relapsed and refractory acquired hemophilia is investigated.


Idiopathic Thrombocytopenia (ITP)

ITP is an acquired autoimmune disease with a decreased platelet count and bleeding complications. We take part in clinical trials evaluating the efficacy and safety of novel treatment options (eg. AMG 531).


    • Global coagulation tests:
      Thromboelastography, endogenous thrombin potential (ETP).
    • Differential coagulation tests:
      Numerous single factor determinations of pro- and anticoagulant and fibrinolytic factors.
    • Constitutional platelet tests:
      Flow cytometric assessment of Fibrinogen (CD 41, CD 61; PAC 1), von Willebrand Factor (CD 42b) and Collagen receptors (CD 29, CD 49b), and of a- and d-granular adhesion receptors (CD 62P, CD 63).
    • Functional platelet tests:
      Aggregation analyses, platelet-plug formation capacity (PFA 100), flow cytometric expression analyses after in vitro stimulation of the thrombin receptor.
