Hypothesis
Can a combined desensitization approach restore enzyme replacement therapy in patients with hypersensitivity reactions?
Conclusion
The combined desensitization approach proved effective in conferring immunotolerance for at least one year in both MPS patients.
Supporting Evidence
- The first patient tolerated weekly laronidase infusions for 13 months after desensitization.
- The second patient achieved complete desensitization after one year, confirmed by negative skin tests.
Takeaway
This study shows that some patients with a rare disease can safely continue their treatment after a special process that helps them not react badly to the medicine.
Methodology
A two-year follow-up after a combined desensitization approach in two MPS patients experiencing hypersensitivity reactions to enzyme replacement therapy.
Limitations
The study is based on only two patients, which limits the generalizability of the findings.
Participant Demographics
One patient was a 35-year-old man with MPS type 1 S, and the other was a 9-year-old child with MPS type 2.
