RESUMO
This case series describes the wide spectrum of clinical presentation, laboratory findings, and morbidity/mortality associated with dengue fever in hematopoietic stem cell transplant recipients, treated in a dengue endemic region. The risk of acquiring viral infections increases manifold after transplant due to the severely immunocompromised state amid conditioning toxicity and immunosuppressive therapy. The classical warning signs of dengue viremia are often masked in posttransplant patients, leading to a missed diagnosis of dengue and grave consequences observed in some of the patients. Accurate and timely diagnosis of dengue fever especially in dengue prevalent areas can prevent the unwarranted complications and reduce the morbidity and mortality associated with dengue in allogeneic/autologous transplant recipients.
