This case report is about an elderly man who presented with a long-standing
history of high-grade fever and weight loss. He initially had only hepatos
plenomegaly, but then developed jaundice. He also had pancytopenia and rais
ed liver enzymes. His septic screen was negative, but he had a positive Mon
ospot test and immunoglobulin G for Epstein-Barr virus. The liver biopsy sh
owed sinusoidal phagocytosis and the subsequent bone marrow aspiration and
biopsy showed significant hemophagocytosis, hence Hemophagocytic syndrome w
as diagnosed. The fever was refractory to antibiotic and anti-tuberculosis
therapy, but it responded only partially to steroids. Full response was onl
y noticed following antiviral treatment in the form of intravenous Ganciclo
vir. The patient's general condition, liver enzymes, bilirubin, hematologic
al parameters and even the weight returned back to their normal range 2 wee
ks after Ganciclovir therapy. Cessation of this drug resulted in relapse of
his symptoms and oral antivirals did not help. Splenectomy, steroid pulse
therapy and immunosuppressive treatment were only partially helpful. Reintr
oduction of Ganciclovir did help for a short period. We conclude that our p
atient had virus-associated hemophagocytic syndrome most likely related to
Epstein-Barr virus infection, which was then confirmed by the splenic biops
y, and that Ganciclovir can be of great help in eradicating the virus and t
reating the disease, provided that it is given for a long enough period.
