Abstract
Lymphocyte transformation and production of lymphocyte-derived chemotactic factor in response to herpes simplex virus antigen were studied in 15 patients with initial genital herpes and 10 controls. The patients underwent frequent genital examinations, viral cultures, and weekly immunological studies for a period of 11 weeks. The production of lymphocyte-derived chemotactic factor was maximal in week 1 of the disease and declined to control levels by week 6. In contrast, lymphocyte transformation was lowest in week 1, reached a maximum by week 4, and declined to control levels by week 11. Production of lymphocyte-derived chemotactic factor in week 1 was significantly lower in nine patients who developed signs or symptoms of systemic herpes infection than in six who had localized disease. In addition, a marked but transient decline in the production of this lymphokine was observed in patients at the time of clinical recurrence. Virus-specific lymphocyte transformation correlated inversely with the duration of genital pain and lesions and did not correlate with the presence of systemic signs or symptoms. These findings indicate that during initial genital herpes infection the dynamics of lymphocyte transformation and those of lymphocyte-derived chemotactic factor production are different, and that the generation of this lymphokine is an early component of the cellular immune response in this disease. Furthermore, adequate produce of lymphocyte-derived chemotactic factor may be important in restricting herpes simplex virus to the genital area and preventing disease recurrence.
