The definitions of complete success, partial success and failure

The definitions of complete success, partial success and failure used in this study were based 3-MA price on criteria of the consensus recommendations of the 2006 International ITI Workshop [13]. Inhibitor and ITI data for patients included in the G-ITI study are presented in Table 1; the majority of patients were children (n = 49).

In primary ITI, 28/32 (87.5%) children had complete or partial success, whereas rescue ITI was successful in 70.6% of children (Table 2). Similar overall success rates were achieved with primary ITI in adults (88.9%) and both adults who underwent rescue ITI had successful outcome (1 complete, 1 partial success) (Table 2). Known predictors of poor response to ITI include failure of previous ITI, inhibitor titre ≥10 BU at ITI Bafilomycin A1 concentration start, peak titre >200 BU, age at ITI start >7 years, and >24 months between inhibitor diagnosis and ITI start [14]. ITI outcomes in the G-ITI cohort were analysed according to these predictors. With regard to peak titre, the complete success rate decreased

continuously with increasing inhibitor titres, whereas the proportion of partial success and failures increased with increasing inhibitor titres (Fig. 1a); similar data were observed for ITI outcome according to inhibitor titre at ITI start (Fig. 1b). In contrast, there were no clear trends in ITI outcome with regard to age at ITI start and time from inhibitor diagnosis to ITI start (Figs. 1c and d). These outcomes concur with those

observed at the Bonn Centre. Analysis of the number of risk factors for poor ITI response showed that, if no risk factors were present, >90% of all patients in the G-ITI study had complete or partial success; MCE公司 an increasing number of risk factors was associated with a decreasing proportion of patients with complete success, whereas the proportion of patients with partial success increased to about one-third of all patients. Considering complete and partial success, overall success rates remained at encouraging levels even in patients with multiple risk factors for poor ITI outcomes. A preliminary assessment of dosage regimens in the G-ITI study showed that the majority of patients received high-dose ITI at least every day (n = 27) or twice daily (n = 17), as primary or rescue ITI, with fewer patients receiving ITI every other day (n = 4) or three times weekly (n = 12). However, there was no clear relationship between daily FVIII dose and success rates. The median time to complete ITI success was approximately 18 months in the primary ITI group and 26 months in the rescue ITI cohort. These results are in the same range as those from the Bonn Centre and the International ITI study [11].
