Brief Summary

Background: Herpes labialis is the result of the presence of Herplex Simplex Virus -1 (HSV-1) and is a common disease in the population. Because of its visibility it has a serious impact on social life and the feeling of well-being in people who suffer from this disease. Until now there is no effective treatment and no remedy for prevention of the virus outbreak. Prebiotics and probiotics have both been shown to have a favorable and supportive effect on the immune system in different health conditions such as influenza, atopic dermatitis and diarrhea. So far no study has addressed the effect of the consumption of pre- and/or probiotics in a population with recurrent herpes labialis. Aim of the study: The present study investigated the effect of pre- or probiotics or a combination of the two on the recurrence of herpes labialis lesions as well as on the immune system in general. Design: 78 Patients were eligible to participate in the study and after a run-in period of two weeks consuming a placebo minidrink were randomized to one of the four experimental groups, these were: placebo minidrink (n=), prebiotic (fructooligosaccharides) minidrink (n=), probiotic (Lactobacillus rhamnosus GG or LGG) minidrink (n=) or a minidrink containing a combination of a pre- and probiotic. These minidrinks were consumed for another 5 weeks. At day 33 of the study the lip most prone to the development of a lesion was stimulated with UVB in order to provoke a lesion. During the entire study period subjects were checked for any clinical signs of a lesion, completed a self-assessment regarding the lesion and a quality of life questionnaire at baseline (day 14) and the end of the study (day 49). In addition, a blood sample was collected at baseline and at the end of the study to be analyzed for general and HSV-specific antibodies, intracellular cytokine concentrations and parameters of the innate immune response such as natural killer cell activity and phagocytosis.
