NCT ID: NCT02499302 Completed - Clinical trials for Fatigue Syndrome, Chronic

Mental Training for CFS Following EBV Infection in Adolescents

Start date: October 2015
Phase: N/A
Study type: Interventional

The general aim of this study is to investigate the effect of an individually tailored mental training program in adolescents developing chronic fatigue syndrome (CFS) after an acute Epstein Barr-virus (EBV) infection. Endpoints include physical activity (primary endpoint), symptoms (fatigue, pain, insomnia), cognitive function (executive functions) and markers of disease mechanisms (autonomic, endocrine, and immune responses).

NCT ID: NCT00005924 Completed - Healthy Clinical Trials

Effects of Long-Term Treatment With Valaciclovir (Valtrex) on Epstein-Barr Virus

Start date: June 23, 2000
Phase: N/A
Study type: Observational

This study will examine the effects of long-term antiviral therapy with valaciclovir (Valtrex) on Epstein-Barr virus infection. This virus infects more than 95 percent of people in the United States. Most are infected in childhood, have no symptoms, and are unaware of their infection. People infected as adolescents or adults may develop infectious mononucleosis, which usually resolves completely. Once infected, most people shed the virus from their throat occasionally, and all carry the virus in their white blood cells for life. This study will determine whether the amount of virus in the blood declines or disappears with long-term valaciclovir treatment. Normal volunteers who are not taking any antiviral medicines and patients enrolled in NIH's protocol no. 97-I-0168 (Evaluation of Valaciclovir for Prevention of Herpes Simplex Virus Transmission) or Glaxo-Wellcome protocol HS2AB 3009 at collaborating centers may be eligible for this study. Patients in the multi-center study must be about to start valaciclovir therapy for at least 1 year. All candidates must be 18 years of age or older. Study participants will be seen in clinic for about 1 hour every 3 months for a year. During these visits, they will provide information about the medicines they are taking, gargle twice with salt water and spit the fluid into a tube, and have blood drawn (no more than 8 teaspoons each visit). The blood and gargled fluid will be tested for the amount of Epstein-Barr virus and antibodies to the virus. (Blood samples will also be tested for HLA type in order to do immunologic studies in the laboratory. HLA is a marker of the immune system that is similar to blood-typing testing.) The results in people taking valaciclovir will be compared with those in people not taking the drug. People whose results show the virus has disappeared from the body will continue to be followed twice a year for 5 years with the blood and gargling tests to continue to look for evidence of virus. Also, people who develop symptoms resembling mononucleosis (e.g., enlarged lymph nodes with fever and sore throat) will be asked to have their blood tested for the virus.
