A 54-year-old woman developed stiffness across the shoulders and a mild headache during a motorcycle tour of the U.S.A. On return to the U.K. she complained of persisting exhaustion and painful muscles. Hospital admission was precipitated by her developing weakness in the right arm and paraesthesiae in the fingers. She was found to be suffering from infectious mononucleosis.

CFIDS (chronic fatigue and immune disfunction syndrome) is also known as CFS (chronic fatigue syndrome), CEBV (chronic Epstein-Barr virus), M.E. (myalgic encephalomyelitis), yuppie flu and by other names. It is a complex illness characterized by incapacitating fatigue (experienced as exhaustion and extremely poor stamina), neurological problems and a constellation of symptoms that can resemble many disorders, including; mononucleosis, multiple sclerosis, fibromyalgia, AIDS-related complex (ARC) and autoimmune diseases such as lupus. These symptoms tend to wax and wane, but any often severely debilitating and may last for many months or years. All sections of the population (including children) are at risk, but women under 45 seem to be most susceptible. The investigators suggest that CFIDS results from dysfunction of the immune system. The exact nature of this dysfunction is not yet well defined, but it can generally be viewed as an unregulated or overactive state which is responsible for most of the symptoms. There is also evidence of some immune suppression in CFIDS. None of the treatments is consistently satisfactory, but some may be helpful: psychotherapy, physiotherapy, exercise programs, acupunctures, small doses of antidepressants, etc.

Lately discovered chronic fatigue syndrome is associated with Epstein-Barr virus infection. The objective of this paper was to detect this syndrome in our patients. 31 patients with cured acute infective mononucleosis were examined by questionnaire, physical check-up and laboratory analyses in order to detect disorders characteristic for chronic fatigue syndrome. Six months after they had been cured, out of 7 patients 5 patients complained of frequent sore throat, fatigue and exhaustion, and a year later, all 5 patients were sleepy and tired all the time. More than a year after the acute illness 19 patients were examined and in 5.6% frequent sore throat and enlarged neck lymph nodes occurred. The gathered results point to disorders characteristic for chronic fatigue syndrome in a high percentage. This pilot study should only be the beginning of examinations of this kind.

The functional units of immune response are lymphocyte clones. Analysis of lymphocyte life span in vivo shows that the overall turnover of CD4 and CD8 lymphocytes does not differ greatly. Recently, molecular methods have been developed which allow a global analysis of T-cell clones responding to an antigen in vivo. We have used a sensitive, modified heteroduplex analysis to follow T-cell clones responding to Epstein-Barr virus in acute infectious mononucleosis (AIM). Strikingly, all the many large clones detected in freshly isolated AIM blood were found within the CD8 fraction. CD4 clonal populations responding to the soluble recall antigen tetanus toxoid could only be detected after in vitro re-stimulation. These data imply that CD4 responses may be more polyclonal than those of CD8 cells and that the size of CD4 clones is more tightly regulated. Several molecular mechanisms may contribute to this. Up-regulation of telomerase allows very large expansions of CD8 cells to occur without exhaustion of proliferative capacity.

Infectious mononucleosis can be disabling to athletes of all ages. Traditionally, long periods of limited physical activity are prescribed. During this time period a significant level of detraining can occur. Sixteen cadets from USMA who were identified as having mononucleosis had their aerobic capacity determined immediately after becoming afebrile. Nine of these cadets then entered a 2-week exercise program while the others remained inactive. After this time period all cadets were allowed to exercise at their own discretion. After an additional 2-week period (4 weeks after becoming afebrile), aerobic capacity was again determined. There were no differences within the groups when comparing VO2 max, METS, or run time to exhaustion on the two aerobic tests. One individual served as a case study with aerobic tests every week for 4 weeks and then 6 months after becoming afebrile. Again, no differences were observed in any variables measured. Thus, prolonged bed rest does not seem to be indicated for the individual recovering from mononucleosis. Noncontact activities can be initiated as soon as the fever disappears.

INTRODUCTION: Chronic fatigue syndrome, termed myalgic encephalomyelitis in the United Kingdom (CFS/ME), is a debilitating condition involving severe exhaustion, cognitive difficulties, educational and vocational losses, and disruption of social activities and relationships. CFS/ME may affect volition (that is, value, interest and sense of competence). PURPOSE: To test Model of Human Occupation (MOHO) concepts by comparing young people with and without CFS/ME in terms of occupational participation, volition and health-related quality of life during infection and over time. METHOD: Three hundred and one people (12-18 years old) diagnosed with glandular fever were evaluated at the time of acute infection (baseline). Six months following diagnosis, 39 of them met the criteria for CFS/ME. A further 39 who recovered were randomly selected and matched to CFS/ME participants. Both groups were re-evaluated at 12 months and 24 months. The Occupational Self Assessment and the Child General Health Questionnaire were used to compare occupational participation. RESULTS: Those with CFS/ME reported lower levels of perceived competency, more difficulties with physical functioning and poorer general health status than those who recovered. CONCLUSION: Those with CFS/ME report lower perceived competency, and compromises in physical functioning, school performance, social activities, emotional functioning and general health. This supports the MOHO assertion that impairments affect volition and quality of life.

The present study discusses about the effects of a combination of probiotics able to stimulate the immune system of patients affected by Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME). To this purpose, patients diagnosed according to Fukuda's criteria and treated with probiotics were analyzed by means of clinical and laboratory evaluations, before and after probiotic administrations. Probiotics were selected considering the possible pathogenic mechanisms of ME/CFS syndrome, which has been associated with an impaired immune response, dysregulation of Th1/Th2 ratio, and high oxidative stress with exhaustion of antioxidant reserve due to severe mitochondrial dysfunction. Immune and oxidative dysfunction could be related with the gastrointestinal (GI) chronic low-grade inflammation in the lamina propria and intestinal mucosal surface associated with dysbiosis, leaky gut, bacterial translocation, and immune and oxidative dysfunction. Literature data demonstrate that bacterial species are able to modulate the functions of the immune and oxidative systems and that the administration of some probiotics can improve mucosal barrier function, modulating the release of proinflammatory cytokines, in CFS/ME patients. This study represents a preliminary investigation to verifying the safety and efficacy of a certain combination of probiotics in CFS/ME patients. The results suggest that probiotics can modify the well-being status as well as inflammatory and oxidative indexes in CFS/ME patients. No adverse effects were observed except for one patient, which displayed a flare-up of symptoms, although all inflammatory parameters (i.e., cytokines, fecal calprotectin, ESR, and immunoglobulins) were reduced after probiotic intake. The reactivation of fatigue symptoms in this patient, whose clinical history reported the onset of CFS/ME following mononucleosis, could be related to an abnormal stimulation of the immune system as suggested by a recent study describing an exaggerated immune activation associated with chronic fatigue.
