The protective effects of passive immunization with two kinds of anti-glycoprotein D (anti-gD) monoclonal antibodies, having different antiviral activities, were investigated in murine herpetic keratitis. One monoclonal antibody, designated M1, had high virus-neutralizing antibody titers, along with undetectable levels of complement-dependent cytolysis (CDC) and antibody-dependent cellular cytotoxicity (ADCC); the other, designated M12, exhibited extremely low titers of virus-neutralization with high level of CDC and ADCC. When systemically administered 24 hours prior to virus inoculation to the cornea, both M1 and M12 almost completely prevented the development of stromal keratitis. The protective efficacy of both was observed to be dose-dependent. Pepsin-treated M1 retained its efficacy in suppressing stromal keratitis, whereas pepsin-treated M12 did not. When the administration of M1 and M12 were delayed, both provided significant (but less complete) protection, up to 24 hours after virus inoculation. These results suggest that both virus neutralization and CDC/ADCC play an important role in preventing virus growth in the corneal stroma during the early stage of corneal infection.

Since the herpes simplex virus locates latently in the ganglia and is reactivated by certain triggers, the important problem in treatment is to prevent or reduce recurrence. The present study investigates the role of mechanical debridement in lessening the recurrence of dendritic keratitis in patients with herpetic epithelial keratitis. Group A was treated with mechanical debridement plus IDU, Group B with IDU alone. Also studied was the effect of steroid subconjunctival injection on herpetic recurrence in patients with herpetic stromal keratitis: Group C was treated with intravenous infusion of pepsin-treated gamma-globulin (PTGG) and steroid subconjunctival injection, Group D with steroid subconjunctival injection alone and Group E with intravenous infusion of PTGG alone. The recurrence rates of dendritic keratitis were 19% in Group A and 40% in Group B (average follow-up periods: 24 and 25 months). The recurrence rates of stromal keratitis were 61% in Group C, 64% in Group D, and 36% in Group E (average follow-up periods: 20, 19 and 15 months). The difference between Groups D and E was statistically significant (chi 2 test, P less than 0.05). The recurrence rates of dendritic keratitis were 18% in Group C, 21% in Group D and 7% in Group E. In conclusion, mechanical debridement tended to reduce the recurrence of herpetic epithelial keratitis and steroid subconjunctival injection to increase the recurrence of epithelial or stromal keratitis.

Experiments have shown that F(ab)'2-fragments can be demonstrated intracellularly. Herpes simplex antibodies in the form of pepsin-split gamma globulin are effective in cases of dendritic keratitis. An additive effect is seen if local antibody therapy is combined with trifluorothymidine treatment.
