[A quantitative evaluation of blood-lymphocyte subpopulation in herpetic ocular disease]

Data on changing contents of blood-lymphocytes' subpopulations in patients with ophthalmoherpes are reported. A higher number of blood cells expressing the surface activation antigens of HLA-DR+, CD71+ and CD95+, a lower number of T-helpers and a reduced value of the immune-regulating index were found to be typical of such changes. A more significant increase in the quantity of CD95+ lymphocytes, as observed in cases of severe ophthalmoherpes versus its moderate clinical course, could be a prognostication criterion. The essential shifts occurring in the T-cells' population denote the status of tension in the immune response provoked by an intensified reproduction of herpes simplex virus (HSV); at the same time, they are indicative of a certain deficit in the immune-protection mechanisms.
