EBV serology was positive for VCA-IgM and IgG, and negative for EBNA-IgG at the age of five years old when the child presented with signs and symptoms suggestive of acute infectious mononucleosis. After 14 months, serological parameters were: positive VCA-IgG, EBNA-IgG and negative VCA-IgM. This serological pattern has been maintained since then even during episodes suggestive of EBV reactivation. PCR amplified a specific DNA fragment from the EBV gp220 (detection limit of 100 viral copies). All twenty-four whole blood samples yielded positive results by PCR, while 12 out of 24 serum samples were positive. We aimed at analyzing whether detection of EBV-DNA in serum samples by PCR was associated with overt disease as stated by the need of antiviral treatment and hospitalization. Statistical analysis showed agreement between the two parameters evidenced by the Kappa test (value 0.750; p &lt; 0.001). We concluded that detection of EBV-DNA in serum samples of immunosuppressed patients might be used as a laboratory marker of active EBV disease when a Real-Time PCR or another quantitative method is not available.<\/jats:p>","DOI":"10.1590\/s0036-46652005000200008","type":"journal-article","created":{"date-parts":[[2006,1,10]],"date-time":"2006-01-10T16:05:44Z","timestamp":1136909144000},"page":"99-102","source":"Crossref","is-referenced-by-count":1,"title":["Detection of EBV-DNA in serum samples of an immunosuppressed child during a three years follow-up: association of clinical and PCR data with active infection"],"prefix":"10.1590","volume":"47","author":[{"given":"Thelma Suely","family":"Okay","sequence":"first","affiliation":[{"name":"University of S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gilda Maria Barbaro","family":"Del Negro","sequence":"additional","affiliation":[{"name":"University of S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L\u00eddia","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"University of S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberto","family":"Raiz J\u00fanior","sequence":"additional","affiliation":[{"name":"University of S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"505","DOI":"10.1002\/jmv.1078","article-title":"Dynamics of Epstein-Barr virus DNA levels in serum during EBV-associated disease","volume":"64","author":"BERGER C.","year":"2001","journal-title":"J. med.
