“…between 200 copies/10 5 peripheral blood mononuclear cells , ≥300/10 5 peripheral blood mononuclear cells [Cesaro et al, 2004], >300/µg DNA [Sirvent-von Bueltzingsloewen et al, 2002], >10 2,5 /µg DNA [Hoshino et al, 2001], >500/75,000 peripheral blood mononuclear cells [Frias et al, 2001], >1,000/10 5 cells [Bacigalupo, 2005], >4,000/µg DNA [Wagner et al, 2004], 6,215/ml blood [Yancoski et al, 2004] and 10,000/µg DNA [Orentas et al, 2003]. As shown in Table 2, EBV load of >100,000 EBV-genome copies /10 5 peripheral blood mononuclear cells significantly predicts EBV lymphoproliferative disease in our study, whereas patients with ≤1,000 EBV-genome copies/10 5 peripheral blood mononuclear cells did not develop a lymphoproliferative disorder.…”
