Introduction: Immune tolerance induction (ITI) is the only treatment to eradicate inhibitors in people with severe haemophilia A with inhibitors. Since the risk of inhibitor development is greater among Black and Hispanic persons, it has been hypothesized that race and ethnicity may influence ITI success. Limited studies have evaluated this hypothesis. Aim: To examine the success of ITI according to race and ethnicity. Methods: Participants who entered the Community Counts (CC) Registry between 2013 and 2017, were aged ≥3 years at study entry, and received ITI were included (n = 559). The proportion of participants with successful ITI was examined with adjusted prevalence ratios (aPRs) and corresponding 95% confidence intervals (95% CIs). Results: Among 559 participants, 56.9%, 19.1%, 18.1% and 4.3% were Non‐Hispanic (NH) White, NH Black, Hispanic and Asian, respectively, and 1.7% were coded as other or missing. Approximately 80% of Hispanic, NH Black and NH White participants had good/very good prognosis, defined as having a pre‐ITI peak inhibitor of < 200 Bethesda Units per millilitre. Nearly 60% of participants (59.7%) achieved successful ITI, 20.7% and 19.5% experienced partially successful or failed ITI, respectively. Successful ITI was non‐significantly lower in NH Black (54.2%; aPR = 0.95, 95% CI 0.62–1.44) and Hispanic (55.4%; aPR = 0.89, 95% CI 0.71–1.13) relative to NH White participants (62.6%). Conclusion: In this study, 60% of participants in the CC Registry had successful ITI, consistent with previous studies. The proportion with successful ITI was generally comparable across racial and ethnic groups with similar prognosis. These findings do not support the hypothesis that ITI response varies according to race or ethnicity. [ABSTRACT FROM AUTHOR]

Introduction Aim Methods Results Conclusions Both men and women can be diagnosed with haemophilia and the experience with haemophilia may be different between men and women.This study aimed to compare patient‐reported outcomes in men versus women with haemophilia.This cross‐sectional study is a post‐hoc analysis of data collected as part of the Haemophilia‐related Distress Questionnaire validation study. Adults aged ≥18 years with haemophilia A or B were recruited from one of two haemophilia treatment centres between July 2017 and December 2019. Outcomes included quality of life, measures of mental and physical health, and overall health. Unadjusted and multivariable linear regression models were used to examine potential mediators of sex‐based differences in outcomes.Of the 139 study participants included (21 women, 118 men), the mean age was 36.9 years and most (89.2%) had haemophilia A. Approximately 85.7% and 26.3% of women and men had mild haemophilia, respectively.  PHQ‐9 depression and PROMIS‐29 Profile anxiety and fatigue scores were significantly higher in women than men in unadjusted and adjusted analyses. There were no statistically significant differences in other outcomes.Women with haemophilia are more likely to experience depression, anxiety, and fatigue than men with haemophilia. This study highlights the need for mental health services to be integrated into the care of women with haemophilia. Future research is needed to understand whether women with haemophilia are more or less likely to experience depression, anxiety, and fatigue than women without haemophilia as well as determine the impact of reduced mental health on clinical outcomes.
