EBV type infection in relation to immune status. (A) CD4 counts are depicted for every HIV-1–infected individual harboring EBV type 1 (type 1), EBV type 2 (type 2), or harboring both type 1 and 2 (type 1+2). Mean CD4 count per group is depicted by the long thin lines, standard deviation by the short thin lines. No statistically significant difference was found between the groups (Kruskal-Wallis). (B) Anti-CD3 responses expressed as cpm/1,000 T cells are depicted for 48 HIV-1–infected individuals harboring EBV type 1 (type 1), EBV type 2 (type 2), or harboring both type 1 and 2 (type 1+2). Mean anti-CD3 response per group is depicted by the long thin lines, standard deviation by the short thin lines. No statistically significant difference was found between the groups (Kruskal-Wallis). (○), LTA; (•), progressors; (▵), NHL.
