Torque teno virus (TTV) is increasingly considered a universal marker of global immune function. The virus is supposed to replicate in lymphocytes, but poor information is available about fluctuations of viraemia after administration of anti-lymphocyte agents. We studied TTV kinetics in a cohort of 70 kidney±pancreas recipients receiving one of two different anti-T-cell induction immunosuppressants. During the first 30 days after anti-T-cell antibody administration, we report kinetics of TTV viraemia compatible with replication in T lymphocytes, and highly dependent on the potency of the anti-T-cell drug administered.
