Abstract
Hemophagocytic lymphohistiocytosis (HLH) is a rare, life-threatening condition due to extensive and uncontrolled immune activation. There is sparse literature on HLH in kidney transplant recipients. We report a case of a 27-year -old male kidney transplant recipient who presented with dengue fever and acute allograft dysfunction. Following improvement in allograft function with supportive treatment, he was found to have worsening pancytopenia with unusually high serum ferritin levels. Bone marrow aspiration performed for pancytopenia revealed hemophagocytosis. A diagnosis of HLH secondary to dengue viral infection was made based on the modified HLH diagnostic criteria (2009). He received supportive treatment and steroids and was discharged in a stable condition with normal kidney allograft functions. To our knowledge, this is the first case report of HLH secondary to dengue viral infection in a kidney allograft recipient managed successfully with timely diagnosis and appropriate treatment.
