Chronic fatigue syndrome (CFS), which is characterized by devastating fatigue, mild fever, lymphadenopathy, headache, myalgia, insomnia and neuropsychiatric disorders, now has drawn much attentions from many physicians, researchers and even peoples in general society world wide. The pathogenesis of CFS is still remains to be clarified and clinico-pathological difference between CFS and mood disorder is controversial. In this paper, CFS would be reviewed in detail.

The case of a young woman with a rare syndrome of acute encephalopathy followed by deafness and retinopathy developing over 1 year is reported. Unlike previously described similar cases, she had considerable systemic symptoms and signs including polyarthralgia-arthritis, diffuse myalgia, malar rash, livedo reticularis, night sweats, and fatigue suggestive of systemic lupus erythematosus. However, results of most immunological investigations were repeatedly normal, including antinuclear antibodies. Anticardiolipin antibodies were elevated on one occasion. Cyclophosphamide has been the most effective treatment for exacerbations of the disease, which have continued to occur over 6 years. This microangiopathic syndrome more likely relates to an immunologically mediated vasculitis of small blood vessels than to a thromboembolic etiology.

Patients with postviral fatigue syndrome (PVFS) usually complain of the skeletal muscle-related symptoms of fatigue and myalgia. It is not surprising therefore that the muscles have recently been the object of intensive studies which have used a variety of biochemical and physiological techniques. The aim of this chapter is to review these findings, and to discuss their significance or otherwise to the presenting symptoms and course of the condition.

A 22-year old unmarried healthy woman was admitted to the Swedish department with low fever, tiredness, SR 75 mm, positive uricult, but no urinary tract symptoms. Urinary tract infection was suspected and treatment was started with norfloxacin. Nevertheless, the urine culture proved to be negative. A few weeks later she had increasing trouble with stiff knee and shoulder joints and the left foot became swollen. The subfebrile status continued, and tonsillitis was suspected and diagnosed. V-penicillin and cefaklor treatment was applied. She was transferred to the infectious diseases ware, where fever was confirmed with leukocytosis (19 x 1 billion/1), C-reactive protein at 66 (normal value 10) mcg/ml, pronounced blood pressure increase (160/130 mm Hg), anemic signs, and pathological liver status with increased transaminases (ASAT 6.3-10.4 and ALAT 8.,8-16 ukat/1). ALP increased slightly to 6 ukat/1. The symptoms of weight loss indisposition, and muscles and joints aches, especially in foot ache continued. Collagen disease was suspected, and she was transferred to the internal medicine department. She regularly had tachycardia and high blood pressure. She had to use crutches for mobility because of the pain. S-albumin was 32 (normal 36- 50) g/l and S-hepatoglobin was 2.7 (normal value .4-1.8) g.l. Various others tests were normal. Ulnaris neuropathy was suspected on the left hand. Intensive blood pressure reducing combination treatment was started with 200 mg x 1 of metoprolol, 10 mg x 2 nifedipin, and 20 mg x 1 enalapril. The Desolett oral contraceptive (containing 30 mcg of ethinyl estradiol and 150 mcg of desogestrel) she had been taking for a few months were discontinued. Quick improvement of clinical and laboratory parameters followed. SR and leukocytosis became normal. The values of ALP, ASAT, and ALAT became normal some days later. She was discharged shortly thereafter, and blood pressure medication was gradually discontinued. In the 1940s there were reports about the hepatotoxic effects of synthetic estrogens followed by carbohydrate, lipid, and protein metabolism alterations. Jaundice has also been reported, and the Swedes have an ethnic susceptibility to it. The global incidence rate is 1/10.000 vs. 1/100 and 1/4000 in Sweden induced by high-dose OCs containing more than 50 mcg ethinyl estradiol, but with low-dose OCs this rate is much lower. Both estrogens and gestagens can increase blood pressure. A 1969 study reported that 22 young women developed arthritis, arthralgia, and myalgia after taking pills for 3- 12 months. Rheumatic symptoms were also recorded with pill use. Thus, it is very likely that OCs were responsible for the patient's symptoms, especially since her status rapidly improved after discontinuing them.

This report describes three Belgian cases of the eosinophilia-myalgia syndrome associated with the use of L-tryptophan-containing products. Three women, aged 51, 53 and 73 years, were taking L-tryptophan for 2 months to 2 years, at 500, 1500, and 2250 mg d-1, respectively. All developed disabling myalgias, fatigue, and a variable skin rash, in association with marked eosinophilia. In one patient, symptoms and eosinophilia reappeared after rechallenge with L-tryptophan. Discontinuation of the drug resulted in gradual disappearance of the symptoms, signs and laboratory abnormalities in two patients. One patient was treated with corticosteroids because of persisting myalgias. Because of the non-specific clinical manifestations, clinicians from all subspecialties of internal medicine might be confronted with such patients and should be aware of this new entity.

Subjective feeling of general fatigue and physiological strain were studied in one hundred female professional employees of industrial worker and full-time nurses. Using an interview questionnaire the feeling of fatigue were studied. The subjects were asked to indicate on the body diagram all the areas of musculoskeletal pain from which they perceived discomfort. Furthermore physical strength test consisting of grip test, back and leg strength test were carried out before and after work on all subjects. The results indicated that the two groups of employees showed different symptoms of "pain" and/or "fatigue," with regard to the different parts of body. It was also noted that the physical strength after work was lower for both groups as compared to before work and even lower for the industrial workers than the nurses. The feeling of fatigue between the two investigated groups was not significantly different, but for the musculoskeletal pain was highly significantly different. The worker group used also more pain-killing drugs for releasing the muscle pain. It was evident that ergonomics intervention for female professional workers was of great importance and urgency, particularly for making the workplace more human. Improvement of the working conditions, better organization of work, and ergonomics interventions are suggested as necessary measures for reduction of pain and feeling of discomfort.

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.

One hundred and four healthy, hepatitis B virus (HBV) seronegative males were enrolled in a single blind, randomized pilot study to compare antibody and clinical responses to a yeast recombinant pre-S2 + S vaccine and a yeast recombinant S antigen vaccine (Recombivax HBR). Participants received either a 12, 24 or 48 micrograms dose of pre-S2 + S vaccine (with a 1:5 ratio by weight of pre-S2 and S antigens) or a 10 micrograms dose of Recombivax HBR by intramuscular injection at 0, 1 and 6 months; their serological and biochemical responses were measured at 0, 1, 2, 3, 6 and 7 months, while their clinical responses were monitored for 5 days after each injection. The proportion of vaccines with minor local or systemic complaints (mainly sore arm, malaise, myalgia, fatigue) and the proportion developing antibody to surface antigen (anti-HBs) were similar for all vaccine groups. Transient elevations in alanine aminotransferase occurred infrequently. By 7 months almost all vaccinees developed anti-HBs, but titres were generally higher among recipients of pre-S2 + S vaccine. Antibody to pre-S2 antigen developed in 70-75% by 2 months and in 91-96% by 7 months. These data imply that the recombinant yeast pre-S2 + S vaccine is as well tolerated and as immunogenic as Recombivax HBR. Further studies are being conducted to assess antibody responses in larger numbers of healthy adults as well as in special populations with sub-optimal responses to currently licensed hepatitis B vaccines.

Fatigue, pain, and emotional upset remain the most common problems affecting humanity and for which we still know so very little. Chronic fatigue syndrome is most likely a number of as yet unproven various undifferentiated illnesses that are exceedingly difficult to distinguish from depression. There probably is a subset of patients with CFS who do have true immune dysfunction and persistent viral infection, and this particular group of patients should be further investigated. This group is the minority of patients who present with chronic fatigue. Although chronic fatigue syndrome may be the result of an organic illness in psychologically susceptible individuals, it remains most important to assess underlying psychologic factors that then need to be addressed. These factors may very likely have a profound effect on immune function, but more research is needed in this area. The diagnostic evaluation of patients with chronic fatigue syndrome should initially focus on causes for fatigue other than Epstein-Barr viral infection. Significant underlying medical conditions should be ruled out, and extensive inquiry into symptoms suggestive of depression and anxiety should be aggressively pursued. Treatment should include psychiatric support and counseling, good nutrition, adequate rest, and a gradual increase in activity. Anti-inflammatory agents and serotonin-replenishing antidepressants are helpful when muscle pain and tenderness are a major part of the patient's symptoms. Psychoactive drugs are useful when indicated. Low doses of antidepressants such as doxepin (10-25 mg at night) are generally well tolerated and have shown efficacy in numerous patients, although there are no reports of controlled trials.

H65-RTA is an immunoconjugate that consists of the A chain of ricin (RTA), a ribosomal-inhibiting protein, coupled to a murine monoclonal antibody (H65) directed against the pan-T-cell antigen CD5. The CD5 antigen is heterogeneously expressed on cutaneous T-cell lymphoma tumor cells, but is not expressed on normal cells except lymphocytes. A phase I trial was therefore conducted in which 14 patients with cutaneous T-cell lymphoma progressive on other therapies were treated with up to three cycles of H65-RTA. The maximal tolerated dose (MTD) of H65-RTA was 0.33 mg/kg/d administered intravenously for 10 days as defined by dyspnea at rest at higher doses. Other reversible side effects included myalgia, mild hypoalbuminemia with weight gain, pedal edema, fatigue, fevers, and chills. Six patients received more than one cycle of H65-RTA without increased side effects compared with the first cycle. Pharmacokinetic analysis showed that peak serum drug levels were dose-dependent, and ranged from 1.13 to 5.56 micrograms/mL, with a terminal half-life ranging from 1.0 to 2.9 hours. The development of antibodies against the immunoconjugate was associated with a lower peak drug level, but not with enhanced side effects. Partial responses lasting from 3 to 8 months were documented in four patients. Three of the responding patients received more than one cycle of H65-RTA in the presence of anti-immunoconjugate antibodies. The results from this phase I trial suggest that H65-RTA is an active drug in the treatment of cutaneous T-cell lymphoma. The immunoconjugate may be safely administered repeatedly, even in the presence of anti-immunoconjugate antibodies, with responses noted. Additional studies at the MTD are needed to define the response rate in this disease.
