Key Points

This research aims to explore the effectiveness of tocilizumab for treating IgA vasculitis in patients with idiopathic multicentric Castleman's disease (iMCD).
Presented two clinical cases of iMCD complicated by IgA vasculitis treated with tocilizumab.
Conducted a literature review on iMCD cases associated with IgA vasculitis and nephropathy.
Analyzed treatment responses to tocilizumab in reported cases.
Both patients responded positively to tocilizumab treatment for IgA vasculitis.
Literature review indicates favorable outcomes of tocilizumab in other cases of iMCD with IgA complications.
Findings suggest a link between IL-6 overproduction in iMCD and the development of IgA vasculitis.
