The only difference was in the degree of reduction in the size of the lesion

42. Conclusion Voriconazole blood levels should probably be monitored Results of therapy of IA may vary substantially based upon: lDisease certainty lSeverity of underlying conditions lHSCT vs non HSCT (???) Role of neutropenia not clear A stable disease might be considered as success in very sick patients

43. Infections in compromised patients are unique because we treat an infection in a patient with another disease. The backgroud noise of the other disease is crucial in evaluating the results of the antinfective therapy
