Human Herpesviruses in Chronic Fatigue Syndrome

That suggested their illness was not due to ciHHV-6 reactivation but to another strain of HHV-6 they’d been exposed to. Over the years, evidence of the involvement of EBV in CFS patients is diminishing (22-26). METHODS: At a single clinic from 1999 – 2001 a total of 4,774 serologic tests were performed in 1135 CFS patients using two immunoassays; Copalis immunoassay and ELISA immunoassay. To permit continuous telemetric monitoring of the electroencephalograph (EEG) and core temperature, mice were implanted with a transmitter [ETA10-F20, Data Sciences International (DSI), St. [26], Berneman et al. All patient PBMC pellets and sera collected were numerically encrypted prior to shipment to our laboratory for analysis. To produce myelin for the brain and nervous system.

About 8% of the entire human genome is believed to be HERVs; however, most of these proviral genes are silenced or only expressed in response to an environmental factor, such as an infecting virus that can activate them in susceptible cells [24]. Research declined since 1995 with eight studies in last 13 years. Despite the skepticism emerging in Europe and the U.S., events were quietly unfolding in a laboratory at the FDA in Rockville, Maryland, that would put Mikovits’s critics back on the defensive. My interest, of course, is in getting patients well and I have to say I dozed off during some of these discussions – partly because I’d had a 4am start and partly because I don’t see the relevance of esoteric immune discussions when it comes to the business of getting patients well! Cermelli and Jacobson [2000] investigated the frequency of HHV-6 DNA detection in MS plaques and the surrounding normal appearing white matter. Although the etiology of CFS remains elusive, some studies have implicated viral infections, including Epstein-Barr virus (EBV), a human gamma herpes virus (γHV), as a potential factor in the pathogenesis of CFS (Glaser and Kiecolt-Glaser, 1998; Jones et al., 1988; Natelson et al., 1994). CFS is most common among people in their 40s and 50s.

NO. “We haven’t discovered all the cytokines involved in immunity. We concluded that fatigue assessments should be performed by not only a questionnaire, such as the CFS, but also by a biomarker search, such as HHV-6, when estimating the caregiver burden for family caregivers of people with dementia. If EBV is reactivated by a stressor, perhaps, Glazer asked, it would be a good idea to try to determine which patients evinced signs of an upregulated stress response and see if they were the same ones with high levels of EBV reactivation. Dr. Montoya reported that 21/25 ME/CFS patients with documented EBV/HHV-6 infection, several of which were severely disabled, improved dramatically with many returning to work or full time activities after 6 months treatment with Valcyte. In uninfected mice, LPS administration induces modest and relatively transient (that is, less than 18 h) hypothermia, reduced running-wheel activity, and alterations in sleep.28 In contrast, mice with latent MuGHV infection develop prolonged hypothermia, hypoactivity, hypersomnolence, and fragmented sleep, all of which persist for as long as 5 d after LPS administration.28 This duration is consistent with the time reported for viral reactivation from latency in MuGHV-infected mice treated with LPS.14 Therefore, as compared with uninfected mice, mice with latent infections appear to show a greater magnitude and duration of LPS-induced behavioral perturbations that may reflect fatigue, perhaps in association with virus reactivation.

Recent studies have shown that the DNA of Herpes-1 virus (the cold sore virus) is located in the pathological plaques in Alzheimer’s disease. Irritability Mild fever (101 degrees Fahrenheit or less) Muscle aches or muscle weakness, occurring throughout the body in multiple locations, and cannot be explained through any known disorder. As stated previously, the presence of active infections correlates with an elevated IgG antibody, despite the lack of IgM antibodies (10-21). Mitochondrial function requires an intact inner membrane where the electron transport chain or energy machinery is located. Her IQ was down by 22 points. Collaborating with the Neuroradiology Department at Stanford to investigate the role of novel magnetic resonance imaging (MRI) techniques (e.g. Our objective was to investigate the cytokine and chemokine response in XMRV-associated CFS.

We begin by helping our patients get a minimum of seven or eight hours of deep, restful sleep. Peterson’s decades long focus on treating immune dysfunctional ME/CFS patients has lead him to assert that 6 months of treatment is necessary to get significant benefits. Exercise techniques, anti-inflammatory dietary habits, herbal or nutritional supplementation) Addressing any underlying past or present bacterial or viral infections (CMV, EBV) Healing the gut mucosa and any leaky gut present Creating a balanced bacterial gut flora. These features are similar to those found in fibromyalgia syndrome. The patients and attending physicians were blinded to the treatment, and 172 patients (86 in each group) completed the study. But the researchers say the study’s power rests in their access to 16 months of blood samples for each patient – a collection allowing for an unprecedented longitudinal look at CFS.
