TAFRO (thrombocytopenia, anasarca, fever, reticulin fibrosis, renal insufficiency, and organomegaly) syndrome is a rare, life-threatening inflammatory condition linked to infections, neoplasms, and idiopathic multicentric Castleman disease. Interleukin (IL)-6 inhibitors are the primary treatment, but refractory cases require alternatives. This study reports the first two pediatric TAFRO cases successfully treated with anakinra, an IL-1 receptor antagonist. Both patients had severe, rapidly progressing disease with multiorgan involvement. Anakinra, combined with corticosteroids, led to significant improvement and remission. We provide a literature review of pediatric TAFRO, confirming its rarity and the partial efficacy of IL-6 inhibitors in many cases.
