Does ITI Actually Work in Hemophilia B – RPTH Journal
RPTH Journal shared a post on LinkedIn about a recent article by Shaoyu Yin et al, adding:
“Immune tolerance induction (ITI) in hemophilia B: does it actually work?
This systematic review makes one thing clear: ITI in hemophilia B is unpredictable and risky.
What the data show:
Across 125 patients:
- Success rates vary wildly (from 12.8 pecent to 100 percent)
- Time to tolerance: approximately 1 to 19 months
- Multiple attempts often needed
The real challenge: safety
Adverse events are not rare, they’re defining:
- Allergic reactions: from 0 to 100 percent
- Nephrotic syndrome: from 0 to 33 percent
These complications are far more common than in hemophilia A.
This is the key issue:
- No standardized definition of ‘success.’
- No uniform ITI protocol
- Small, heterogeneous cohorts
We’re comparing apples to oranges across studies.
Clinical insight
- ITI can still work, even after failure or allergic reactions
- But nephrotic syndrome is a major red flag (often treatment-limiting)
- Immunosuppression is widely used but doesn’t eliminate risk
Big picture
Unlike hemophilia A, where ITI is established: Hemophilia B remains a high-risk, low-predictability space
And until we standardize protocols: We’re optimizing therapy without a common playbook.”
