Background: The cause of fatigue is not well understood. It can be felt differently by different people. Some people think there are different types of fatigue, with different causes. Researchers think a therapy to treat one type of fatigue in one condition should be able to treat that type of fatigue in other conditions.

Summary: Epstein-Barr virus (EBV) is a member of the human herpes virus family that infects more than 95 percent of the U.S. population. Most infections occur in childhood and cause no symptoms; in adolescents and adults, EBV often causes infectious mononucleosis. It has also been associated with certain forms of cancer. Chronic Epstein-Barr virus (CAEBV) is a rare disease, primarily of children and young ...

Summary: The Munich cohort study MUC-CFS aims at the characterization and long-term follow-up of myalgic encephalitis/chronic fatigue syndrome (ME/CFS) in young people aged up to 25 years, as well as at the identification of pathomechanisms, biomarkers, and targets for future treatment approaches.

Summary: This is a single-center, prospective, randomized, double-blind (pharmacotherapy), placebo-controlled, and comprehensive rehabilitation phase II clinical trial to determine the usefulness of pregabalin in a new indication (post-COVID chronic fatigue syndrome). Patients will be randomized in a 1:1:1:1 ratio to pregabalin (75-300 mg daily in two divided doses), comprehensive rehabilitation with a pla...

Background: Epstein-Barr virus (EBV) causes most cases of infectious mononucleosis (mono). Up to 1 in 10 people who get mono can have fatigue that lasts more than 6 months. One out of 100 people can have severe complications. EBV is also associated with several types of cancer. Researchers want to test an EBV vaccine.

Summary: The aim of this multi-center, two-armed, randomized controlled trial is to assess the effect of a novel internet-based therapist-assisted treatment program One step at a time designed for the treatment of patients with moderate to severe functional somatic disorders (FSDs). The trial will enroll 166 patients with FSD who will be randomized (1:1) to either the experimental condition (14 weeks' trea...

Summary: This study is an 8-week single center, randomized, double-blind, placebo-controlled, flexible titration trial evaluating the efficacy of solriamfetol in the treatment of fatigue symptoms in adult patients with chronic fatigue syndrome. Subjects will be randomized to a solriamfetol group or placebo group. The investigators will utilize an intent to treat model and impute data. The overall goal of t...

Summary: Subjects have a type of lymph gland disease called Hodgkin or non-Hodgkin Lymphoma or T/NK-lymphoproliferative disease or severe chronic active Epstein Barr Virus (CAEBV) which has come back, is at risk of coming back, or has not gone away after treatment, including the best treatment we know for these diseases. Some of these patients show signs of virus that is called Epstein Barr virus (EBV) tha...

Summary: This study aims to assess the effect of Antrodia cinnamomea mycelia on immune modulation in subhealth people.

Summary: Chronic fatigue syndrome/myalgic encephalomyelitis (ME/CFS) is an unexplained multisymptom/multisystem disorder for which there are currently no validated treatments. The present exploratory clinical trial aims to advance our understand of the mechanisms of in situ GSH synthesis control through assessment of the response of brain GSH and plasma markers of oxidative stress to different doses of NAC...

Summary: Investigators have previously used this sort of therapy to treat Hodgkin or non-Hodgkin lymphoma that is associated with the virus that causes infectious mononucleosis (mono or the kissing disease), Epstein-Barr virus (EBV). EBV is found in cancer cells of up to half of all patients with Hodgkin's and non-Hodgkin lymphoma. This suggests that it may play a role in causing lymphoma. The cancer cells...

Summary: Following acute COVID-19, some patients develop a group of debilitating symptoms that include fatigue, orthostatic intolerance, difficulty with attention and concentration (often called brain fog), myalgias and disrupted sleep. The term Long COVID is used to describe these symptoms after the initial viral infection has passed. These symptoms are the same as those that define myalgic encephalomyeli...
