Immune, stress, and mood markers related to recurrent oral herpes outbreaks.
This was a prospective and longitudinal study designed to compare daily mood states and weekly changes in plasma levels of immune and neuroendocrine markers with recurrent herpes labialis lesion recurrences during a 3-month period among 9 subjects. Results from a paired t test showed that there was a significant decrease in plasma levels of natural killer cells and serum levels of epinephrine from the week before recurrent herpes labialis lesion occurrence (T1,9 = 2.70; p < 0.05) to the week of recrudescence (T1,9 = 2.41; p < 0.05). On the other hand, in the week before recrudescence the number of natural killer cells was 58 units higher than the overall group mean for natural killer cell level (227 units). In the week before outbreak, elevated natural killer cell numbers were associated with a mood of discontentment (r = 0.64; p = 0.05). Elevated levels of epinephrine averaged across the 12 weekly blood draws were significantly correlated with higher scores on affect intensity (r = 0.72; p < 0.05). This study provides new data on the pattern of changes in stress, mood states, and immune and neuroendocrine markers associated with the recurrence of perioral herpes lesions. Putative mechanisms linking neuroendocrine and immune function are discussed.
