Recently, the author has identified 19 patients who have complained of marked fatigue that had abnormal responses to copper test bracelets or necklaces. At this time, 8 have been shown to have at least one enzyme deficiency in the heme pathway. These patients have been diagnosed with multiple sclerosis, chronic fatigue syndrome and other non-specific diagnoses. A lengthy but still limited review of the literature was performed regarding the following conditions: multiple sclerosis (MS), hepatic porphyria (HP), chronic fatigue syndrome (CFS) and paralytic polio (PP). The text will focus on similar epidemiologies, laboratory findings and clinical courses. Copper as a common but not unique etiologic agent will be discussed; as will the heme pathway, a biologic process that may be disordered in all.

Chronic fatigue syndrome represents a poorly defined disease with protean clinical manifestations, the majority of them expressed as a muscle fatigue or as inability to maintain the expected muscle strength. In the present work we studied muscle function and muscle histopathology in 20 patients fulfilling the proposed criteria for chronic fatigue syndrome. Special interest is directed towards the immunoreactive expression of class I MHC molecules comparing some inflammatory and virus-related myopathies with muscles from chronic fatigue syndrome. Only minor morphological changes were detected in 9 out of 20 patients of the series. The nonspecific morphological changes in muscle tissue and the lack of class I MHC expression does not support the viral etiology of muscle fatigue in chronic fatigue syndrome. In contrast with the reported clinical improvement with high doses of essential fatty acids, our patients' clinical condition did not improve after three months of L-carnitine therapy.

Chronic fatigue syndrome (CFS) is a severely disabling illness of uncertain aetiology. It is characterized by a chronic, sustained or fluctuating sense of debilitating fatigue without any other known underlying medical conditions. It is also associated with both somatic and neuropsychological symptoms. Both physical and laboratory findings are usually unremarkable. Regional cerebral blood flow (rCBF) was assessed in 60 clinically defined CFS patients and 14 normal control (NC) subjects using 99Tcm-hexamethylpropyleneamine oxime (99Tcm-HMPAO) single photon emission computed tomography (SPECT). Compared with the NC group, the CFS group showed significantly lower cortical/cerebellar rCBF ratios, throughout multiple brain regions (P < 0.05). Forty-eight CFS subjects (80%) showed at least one or more rCBF ratios significantly less than normal values. The major cerebral regions involved were frontal (38 cases, 63%), temporal (21 cases, 35%), parietal (32 cases, 53%) and occipital lobes (23 cases, 38%). The rCBF ratios of basal ganglia (24 cases, 40%) were also reduced. 99Tcm-HMPAO brain SPECT provided objective evidence for functional impairment of the brain in the majority of the CFS subjects. The findings may not be diagnostic of CFS but 99Tcm-HMPAO SPECT may play an important role in clarifying the pathoaetiology of CFS. Further studies are warranted.

A 40 year old man suffered eight years of vague but disabling symptoms, initially thought to be related to post viral fatigue syndrome, but ameliorated by the removal of a large atrial myxoma. The diagnosis of atrial myxoma is notoriously difficult, but should be excluded by echocardiography if there are predominant symptoms of progressive exertional dyspnoea, even in the absence of cardiological signs.

We have treated a case of chronic fatigue syndrome with atopic diathesis was had suffered general malaise, low grade fever, swelling of the lymph nodes, myalgias and arthralgias for a long time. A 29-year-old female, who had been treated for atopic dermatitis for 5 years, complained of general malaise in May 1990. She was admitted to the nearest hospital in December 1990 because of low grade fever, swelling of the lymph nodes and an elevation of antinuclear antibody (2520x). She was transferred to our hospital in May 1991. A diagnosis of collagen disease was not compatible with her condition. In addition to general malaise, fever and lymph node swelling, headache, myalgias, muscle weakness, arthralgias and insomnia were observed, and a diagnosis of chronic fatigue syndrome was made based on the working case definition proposed by Holmes et al. Although eosinophilia, a high serum level of IgE, and elevation of RAST scores, low NK and ADCC activity, and a reduced level of NK cells in the peripheral blood were detected, serum antibodies to a number of viruses were in the normal range. Treatments with non-steroid anti-inflammatory drugs, minor tranquilizers and antidepressant drugs were not effective at all. An administration of magnesium sulphate was intravenously performed once a week in order to improve her condition, especially severe general malaise. After about 6-week's administration of magnesium sulphate, she noticed reduced easy fatigability and an improvement in her impaired daily activities. Finally she was able to leave the hospital in January 1992.(ABSTRACT TRUNCATED AT 250 WORDS)

Effects on systemic and pulmonary haemodynamics, renal electrolyte excretion, and plasma concentration of vasopressin, catecholamines, electrolytes and proteins in response to intracerebroventricular infusions of [Val5]-angiotensin II (ANG II) at 1, 2 and 4 pmol kg-1 min-1 in isotonic saline for 30 min were studied in conscious sheep (n = 6). Vehicle control infusions were performed in four of the animals. All three doses of ANG II were expected to increase CFS concentration of the peptide above physiological levels. All ANG II infusions were noticed to be dipsogenic, but the animals were not allowed to drink freely until at the end of the experiments (at 120 min post-infusion). The systemic arterial blood pressure increased significantly only in response to 2 and 4 pmol kg-1 min-1, concomitant with an increase of the systemic vascular resistance, whereas the cardiac output and heart rate remained unchanged. The central venous pressure increased only after administration of the highest ANG II dose, while pulmonary artery, and capillary wedge pressures were unaffected during all experiments. The plasma protein and K concentration fell in response to ANG II administration. Also here, the effects were significant only at 2 and 4 pmol kg-1 min-1. The plasma levels of vasopressin, noradrenaline, adrenaline and dopamine did not change significantly in response to any of the infusions. The renal Na excretion increased by 100-400%, but not in a strictly dose-dependent manner. Much smaller and more variable effects were seen on the renal K excretion.(ABSTRACT TRUNCATED AT 250 WORDS)

We recorded event-related brain potentials (ERPs) from 13 patients with chronic fatigue syndrome (CFS) and 13 matched normal controls. To assess attentional and memory deficits in CFS patients, we used a short-term memory task in which events occurred in different spatial locations and the patients made a rapid-response (RT) when a letter in a relevant location matched a letter in the prememorized set (Attention paradigm). Time-on-task effects on the ERP and behavioral measures were assessed over the 2 1/4-hour duration of this task. Both groups also performed a visual Oddball paradigm, with an RT, before and after the Attention paradigm. The patients' RTs were much more variable and, in nine of 13 cases, slower than the mean RT of the controls in both paradigms. The patients' memory performance was not significantly different from that of the controls and there were no group differences in the overall amplitude, latency, or scalp distribution of the N1, P2, N2, or P300 components of the ERP in either paradigm. The ERP and performance data from both paradigms suggest that perceptual, attentional, and short-term memory processes were unaffected in CFS patients and that the differences were limited to response-related processes.

This article presents current research on chronic fatigue syndrome, which currently afflicts mostly females between the ages of 25 and 55. Because depression is a common symptom of chronic fatigue syndrome, mental health practitioners are often involved with the victims and must formulate an appropriate treatment strategy that considers the physiological, intrapsychic, interpersonal, and environmental aspects of the client. This article includes case material focusing on a woman who was medically diagnosed with the Epstein-Barr virus and was in psychotherapy with the author. The difficulty of managing the interplay of the real health problems and the emotional issues presented by the client is highlighted.
