Implication

Retrospective analysis shows high anti-ADAMTS13 IgG levels indicate delayed normalization in iTTP patients, suggesting additional treatment may be needed.

Key Points

High anti-ADAMTS13 IgG levels predict delayed normalization of ADAMTS13 activity after plasma exchange in iTTP patients, impacting treatment strategies.
Post-TPE measurements of anti-ADAMTS13 IgG showed a significant correlation with the time to achieve partial ADAMTS13 remission.
Retrospective longitudinal analysis compared caplacizumab-treated iTTP patients to historical controls without caplacizumab, revealing treatment impacts over time.
Identifying patients at risk of delayed ADAMTS13 normalization may inform the need for more intensive immunosuppressive therapy.
