Spontaneous resolution of Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis.
Secondary hemophagocytic lymphohistiocytosis (sHLH) is a reactive, proliferative disorder of the immune system resulting in lymphohistiocytic proliferation, hemophagocytosis, and cytokine dysregulation. The most common infectious trigger in sHLH is Epstein-Barr virus (EBV-HLH). Current treatment protocols for EBV-HLH have a cure rate of approximately 75%; however, there are significant toxicities associated with these therapies. We present two patients with EBV-HLH who experienced spontaneous resolution of their disease prior to the initiation of therapy, suggesting there may be a subgroup of patients with EBV-HLH who do well with conservative management and can avoid potentially toxic therapies.
