Herpes labialis (HL) is the result of the presence of a virus called HSV-1 and is a common disease. Because of its visibility due to cold sores it has a serious impact on social life. Until now there is no effective treatment to prevent virus outbreaks. However, 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 it is possible that they are able to have a favourable effect also on HL. A recently completed pilot clinical trial (Protocol Number 08-SBUS-2-GRA-01, EVIM-1) was completed using a fermented milk (minidrink) containing a combination of L. rhamnosus and FOS; it showed promising results in the reduction of HL recurrences in a population of 78 subjects with HSV-1. The study investigated the effect of pre- or probiotics or a combination of the two on the recurrence of HL lesions as well as on the immune system in general, showing that the consumption of a minidrink containing the probiotic L. rhamnosus or a minidrink containing a combination of L. rhamnosus and FOS reduced the occurrence and the incidence of recurrent HL lesions. Aim of this study: corroborate whether the consumption of a minidrink containing a combination of L. rhamnosus and FOS results in less recurrence and a better progression of HL lesion, in a larger population. In addition, the response of the consumption of the minidrink on the QoL and the response on immunity specific biomarkers were evaluated. Design: 152 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 two experimental study groups: placebo minidrink (n=79) and a minidrink containing a combination of a pre- and probiotic (n=78). These minidrinks were consumed until the end of the study (day 140). At day 33 of the study the lip most prone to the development of a lesion was stimulated with UVB 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 QoL questionnaire at baseline (day 14), at day 49 and the end of the study (day 140). In addition, a blood sample was collected at baseline, at day 49 and at the end of the study to be analyzed for HSV-specific antibody concentrations , to check immune system specific functions.

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.

Recurrent herpes labialis are usually a minor malady of limited duration, although they are often painful and are uniformly discomforting for patients. Oral antivirals represent an advance in the treatment of recurrent herpes labialis, but the clinical implications are modest. Randomized, controlled clinical trials have shown that oral antivirals decrease the duration of lesion episodes and pain by approximately one day. In recurrent HSV infections including herpes labialis, many instances of viral re-activation occur without symptoms, and can only be identified by detection of virus on the lips of infected individuals. In these cases, the virus is cleared from the local site without the development of a classical ulcerative herpes lesion. In the other cases, the triggered specific immune response rapidly stops viral replication in the skin and also causes the development of the herpes lesion prodrome and a considerable part of the symptoms associated with a classical ulcerative herpes lesion. One could therefore predict that treatment with an antiviral drug alone would help the immune system in shortening the virus replication, but may not substantially reduce the disfiguring symptoms caused by the immune reaction. In dermatology, the principle of using an anti-inflammatory drug improve clinical outcomes by reducing inflammation-related symptoms associated with the infection has been well established. We have found that a topical formulation of VDO is useful for alleviating pain and inflammation associated with infection caused by herpes virus.
NCT01985321
The purpose of this study is to determine if Merlin, a mixture of ethanol and glycolic acid, is safe and effective in the treatment of cold sores. Subjects who meet the requirements to participate in the study will be put randomly, and equally, into one of two groups: 1) a group receiving Merlin to treat their cold sore; or 2)a group receiving a placebo of just ethanol to treat their cold sore. Neither the subject nor the site will know which treatment they will be getting. Once the subject has been assigned to a treatment group, they will be given a kit containing a bottle of the treatment and special swabs to apply the liquid. The subject will be told to take the kit home and wait until they think they are starting to get a cold sore. Once a subject begins to feel something or see something that they think is the start of a cold sore, they are to immediately call the clinic. Once the clinic confirms that the subject is in fact starting to get a cold sore, the subject will be told to open the kit and begin treatment. From the start of treatment, there will be twelve (12) treatments, with either Merlin or placebo, applied six (6) hours apart, up to 3 per day, over the next 96 hours (4 days). Each treatment of Merlin or placebo is made up of three (3) applications given twenty (20) minutes apart, for a total of thirty-six (36) applications. FOr each application, the subject will use the special swab to put the Merlin or placebo solution on their cold sore. Subjects will need to report daily to the clinic for a minimum of 3 consecutive days, until either the cold sore is completely healed or 14 days from the start of treatment, whichever comes first. At each clinic visit the cold sore will be observed to determine at what stage it is at or if it has healed. The subject will also be asked how they are feeling. Subjects will also be told to record in a diary the time of each application of Merlin or placebo. They will also be asked to record how much pain, if any, related to the cold sore, that they are feeling.

NCT00230867
Currently approved drugs for the treatment of herpes labialis (cold sores) exhibit low levels of efficacy due to the limited ability of the drugs to penetrate the skin to the site where the herpes virus is replicating. Iontophoresis uses electric current to enhance the delivery of drugs through the skin. This trial is testing a new iontophoretic device for the delivery of acyclovir cream to treat cold sores.
