Background and Aim Vasculitides are rare inflammatory disorders that sometimes can be difficult to diagnose due to their diverse presentations. This review examines the use of Artificial Intelligence (AI) to improve diagnosis and outcome prediction in vasculitis.

Methods A systematic search of PubMed, Embase, Web of Science, IEEE Xplore, and Scopus identified relevant studies from 2000 to 2024. AI applications were categorized by data type (clinical, imaging, textual) and by task (diagnosis or prediction). Studies were assessed for risk of bias using PROBAST and QUADAS-2 tools.

Results Forty-six studies were included. AI models achieved high diagnostic performance in Kawasaki Disease, with sensitivities up to 92.5% and specificities up to 97.3%. Predictive models for complications, such as IVIG resistance in Kawasaki Disease, showed AUCs between 0.716 and 0.834. Other vasculitis types, especially those using imaging data, were less studied and often limited by small datasets.

Conclusion The current literature shows that AI algorithms can enhance vasculitis diagnosis and prediction, with deep and machine learning models showing promise in Kawasaki Disease. However, broader datasets, more external validation, and the integration of newer models like LLMs are needed to advance their clinical applicability across different vasculitis types.

This study did not receive any funding

I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.

Yes

I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.

Yes

I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance).

Yes

I have followed all appropriate research reporting guidelines, such as any relevant EQUATOR Network research reporting checklist(s) and other pertinent material, if applicable.
