Steroids can be given for severe GI or renal involvement as well as immunosuppressants, plasmapheresis, or transplant if severe renal symptoms.IgA vasculitis symptoms typically resolve within 4-6 weeks but 1/3 of patients will have relapse or recurrence within 1 year. Monitoring for renal involvement is important.SourcesReid-Adam, Jessica.
