ro13-9904 and Cytomegalovirus-Infections

The authors present the case of an apparently immunocompetent 9-year-old child with probable cytomegalovirus encephalitis. The clinical picture was characterised by fever, frontal headache and behavioural changes, associated with visual and auditory hallucinations. Cerebrospinal fluid (CSF) biochemistry and brain CT were normal. Electroencephalography showed left temporal paroxysmal activity. Diagnosis was based on cytomegalovirus (CMV) DNA detection on the CSF by PCR. Acyclovir and ceftriaxone were given until herpes simplex virus (HSV) and bacterial encephalitis were ruled out. Rapid resolution of fever and complete clinical recovery was observed. Remarkably, anti-CMV serum antibodies were not detected on admission or until 6 months later. This discrepancy led us to question the presence of an impaired specific host humoral response, immune evasion by the virus or a false-positive result for CMV DNA in CSF.

Kawasaki disease (KD) is an acute, febrile, and multisystem vasculitis of early childhood with a striking predilection for the coronary arteries. The most significant complication is coronary artery abnormalities, including coronary aneurysms. The etiology of KD remains unknown. Many infectious agents including viruses have been postulated as possible causes of KD. But standard microbiologic techniques, molecular methods and serologic investigations have failed to identify an etiologic agent. We described a patient with atypical KD during cytomegalovirus infection.
