Background: Kidney transplant patients are susceptible to a variety of infections in the post-transplant period due to the use of immunosuppressant medications. Ehrlichiosis is a rare infection in solid organ transplant recipients with signs and symptoms that mimic rejection and other viral infections. Hemophagocytic lymphohistiocytosis (HLH) is a potentially fatal hyperinflammatory syndrome that can be triggered by infections.
Methods: We describe a pediatric kidney transplant recipient who experienced secondary HLH due to ehrlichiosis within the initial post-transplant month.
Result: Our patient improved after treatment with doxycycline, corticosteroids, and intravenous immunoglobulin (IVIG).
Conclusion: Clinicians should consider infections such as ehrlichiosis as a potential cause of illness in febrile solid organ transplant recipients in immediate post-transplant period, especially when accompanied by a compatible exposure history.
Keywords: ehrlichiosis; fever; hemophagocytic lymphohistiocytosis; kidney transplant.
