CD23 is induced in B cells upon infection by Epstein‐Barr virus (EBV) and a soluble form (soluble CD23: sCD23) is found in culture supernatants from EBV‐transformed B cell lines. Based on these observations, we measured serum sCD23 levels in patients with infectious mononucleosis (IM) caused by EBV infection. Sera from patients with IM at the time of diagnosis contained more sCD23 than sera from normal control subjects. Changes in serum sCD23 levels during the course of disease showed that serum sCD23 levels were elevated at the time of diagnosis and they decreased to the normal levels during the convalescent phase defined by the improvement of symptoms of IM. These results indicate that the elevated levels of sCD23 were observed at the acute phase of IM and may be useful in diagnosing IM. J. Med. Virol. 53:384–387, 1997. © 1997 Wiley‐Liss, Inc.
