Acyclovir (ACV) has an ED50 of 0.3 microM against EBV replication in vitro. Based on these and other data we carried out a pilot, double-blind, placebo-controlled trial of ACV for treatment of infectious mononucleosis. Only patients with relatively severe illness requiring hospital management were enrolled. Ten subjects with proven infectious mononucleosis received placebo and 10 ACV. The drug was administered intravenously at 8-hourly intervals in a total daily dosage of 1500 mg/m2 for 5 days. Preliminary analyses of the results indicate that the drug interrupted virus excretion in the oropharynx transiently but had no effect on ability to generate lymphocytic lines from peripheral blood. Symptoms and signs unaffected by ACV were splenomegaly, lymphadenopathy, lethargy, fever and pharyngitis. There was significantly more rapid regain of weight in the ACV-treated group. On the basis of these results we have instituted an out-patient trial of orally administered ACV in patients with less severe illness earlier in its course. We have also begun in-vitro tests of other drugs that might prove to be effective against Epstein-Barr virus infection, and have shown that 9-1 (1,3-dihydroxy-2-propoxymethyl)guanine (BW759) has an ED50 of 0.05 microM.

We present the case of a patient with Epstein-Barr virus (EBV) encephalitis who developed abnormal white matter lesions during the chronic phases of the infection. A 2-year-old-boy was admitted for a 2 day history of decreased activity with ataxic gait. The results of the physical examination were unremarkable except for generalized lethargy and enlarged tonsils with exudates. Brain magnetic resonance imaging (MRI) at admission showed multiple high signal intensities in both basal ganglia and thalami. The result of EBV polymerase chain reaction (PCR) of the cerebral spinal fluid was positive, and a serological test showed acute EBV infection. The patient was diagnosed with EBV encephalitis and recovered fully without any residual neurologic complications. Subsequently, follow-up MRI at 5 weeks revealed extensive periventricular white matter lesions. Since the patient remained clinically stable and asymptomatic during the follow-up period, no additional studies were performed and no additional treatments were provided. At the 1-year follow-up, cranial MRI showed complete disappearance of the abnormal high signal intensities previously seen in the white matter. The patient continued to remain healthy with no focal neurologic deficits on examination. This is the first case of asymptomatic self-limited white matter lesions seen in serial MRI studies in a Korean boy with EBV encephalitis.

A 16-year-old male patient with known hereditary spherocytosis presented with a 4-day history of chest pain and lethargy. On admission, he had a low-grade fever and was grossly anaemic; examination revealed splenomegaly. An ultrasound scan confirmed splenomegaly with areas of splenic infarction. Subsequent tests suggested possible Epstein-Barr virus infection. The patient recovered well and had a functional spleen on discharge. This case report presents an unusual complication of isolated hereditary spherocytosis.
