Sleep, Epstein-Barr virus infection, musculoskeletal pain, and depressive symptoms in chronic fatigue syndrome

Abstract:

Sleep physiology, viral serology and symptoms of 14 patients with chronic fatigue syndrome (CFS) were compared with 12 healthy controls. All patients described unrefreshing sleep and showed a prominent alpha electroencephalographic nonrapid eye movement (7.5-11.0 Hz) sleep anomaly (p less than or equal to 0.001), but had no physiologic daytime sleepiness.

There were no group differences in Epstein-Barr virus (EBV) antibody titers. The patient group had more fibrositis tender points (p less than 0.0001), described more somatic complaints (p less than 0.0001), and more depressive symptoms (p less than 0.0001). Patients with CFS do not show evidence for a specific chronic EBV infection, but show altered sleep physiology, numerous tender points, diffuse pain, and depressive symptoms. These features are similar to those found in fibromyalgia syndrome.

Pain syndromes, disability, and chronic disease in childhood

Abstract:

Childhood disability and chronic disease are common, and their prevalence is increasing as children survive with conditions that were previously fatal. It is important that physicians in training learn about disability and handicap, and the functioning of multidisciplinary teams to manage these problems. Chronic ill-health is often very expensive to manage, and some serious and creative thinking about the best way to fund such health care is urgently needed.

Pediatric rheumatologists are involved with the care of many children with chronic and recurrent musculoskeletal pain; however, they have not perhaps focused enough research effort on the investigation of pain and its management. Whether reflex neurovascular dystrophy, fibromyalgia, and chronic fatigue syndrome are part of a disease continuum is unclear, but it seems probable that psychosocial problems are often important contributing factors in all three conditions.

Immunoglobulin subclass deficiencies are being increasingly delineated, occurring in chronic fatigue syndrome as well as many other disease states. Their clinical relevance still remains, for the most part, uncertain. Short stature occurs in many chronic illnesses, and the role of growth hormone treatment in these conditions is beginning to be investigated.

Chronic fatigue syndrome in northern Nevada

Abstract:

The clinical and laboratory findings from studies of patients with chronic fatigue syndrome (CFS) from northern Nevada are summarized. Physicians caring for these patients have estimated that greater than 400 patients with CFS from northern Nevada and nearby communities in California were identified between 1984 and 1988.

As a result of these studies, a cluster of clinical and laboratory features associated with the illness in moderately to severely affected patients has been identified: profound fatigue of prolonged duration; cervical lymphadenopathy; recurrent sore throat and/or symptoms of influenza; loss of cognitive function manifested by loss of memory and loss of ability to concentrate; myalgia; impairment of fine motor skills; abnormal findings on magnetic resonance imaging brain scan; depressed level of antibody to Epstein-Barr virus (EBV) nuclear antigen; elevated level of antibody to EBV early antigen restricted component; elevated ratio of CD4 helper to CD8 suppressor cells; and strong evidence of association of this syndrome with infection with human herpesvirus 6.

More-serious and longer-lasting neurologic impairments, including seizures, psychosis, and dementia, have also been observed in some of these patients.

High frequency of fibromyalgia in patients with chronic fatigue seen in a primary care practice

Abstract:

We administered a standardized history questionnaire and performed a tender point examination on 27 patients with debilitating fatigue of at least 6 months duration, seen in a primary care practice, as well as on 20 patients with fibromyalgia.

Sixteen of the 27 patients with chronic fatigue met the full criteria for the working case definition of chronic fatigue syndrome (CFS). Eight patients with chronic fatigue denied having any current persistent, diffuse musculoskeletal pain, and their tender point scores were similar to those in 10 normal control subjects. In contrast, 19 patients with chronic fatigue (70%) had persistent, diffuse musculoskeletal pain.

The results of their tender point examinations were similar to those of the patients with fibromyalgia. Thus, the majority of these patients with debilitating chronic fatigue, including those who met criteria for CFS, met the historical and tender point diagnostic criteria for fibromyalgia. The presence of current musculoskeletal pain will identify those CFS patients who have fibromyalgia.

Sleep and symptoms in fibrositis syndrome after a febrile illness

Abstract:

Sleep physiology and symptoms of 9 patients with fibrositis syndrome secondary to a febrile illness were compared to 9 patients with fibrositis syndrome who did not attribute their symptoms to a febrile illness and to 10 healthy controls.

Both patient groups showed an alpha EEG (7.5 to 11 Hz) nonrapid eye movement sleep anomaly, had similar observed tender points, and self-ratings of musculoskeletal pain.

These findings suggest that patients with postfebrile fibrositis have a nonrestorative sleep disorder characteristic of patients with fibrositis syndrome and share similar symptoms with patients who have a “chronic fatigue syndrome.”
