Protein A immunoadsorption column versus splenectomy in the treatment of steroid-resistant immune thrombocytopenic purpura. A cost-effectiveness analysis.
The protein A immunoadsorption column is a new treatment for immune thrombocytopenic purpura (ITP). We used a decision-analytic approach with a Markov process to model the cost effectiveness of this treatment compared with splenectomy for steroid-resistant ITP patients. Data informing the model were obtained from published literature, a panel of physicians, and public databases. We found initial treatment with the protein A immunoadsorption column to be less expensive and more effective than initial treatment with splenectomy.
