Alleged link between hepatitis B vaccine and chronic fatigue syndrome

Comment on: Alleged link between hepatitis B vaccine and chronic fatigue syndrome. [CMAJ. 1992]

 

It was with great interest that I read this article in the Jan. 1, 1992, issue of CMAJ (146: 37-38). As a 4th-year medical student at the University of Ottawa I was pleased to read of a possible medical (albeit iatrogenic) explanation for my complaints of fatigue and ill health.

You see, in my first year of medical school I was engaged in an elective in general surgery and, as a precaution, received complete hepatitis B prophylaxis. Now, some 3 years later, I find that I can hardly drag myself out of bed every morning at dawn, and it is a struggle to keep my eyes open to read Harrison’s every night, not to mention the nearly impossible task of stifling yawns and the embarrassment of nodding off at rounds and lectures after a 36-hour shift.

I also find it fascinating that most of my classmates (who have also received the hepatitis B vaccination series) have similar complaints of excessive daytime somnolence, lack of energy and listlessness as they too struggle to complete a work week in excess of 70 hours.

I am sure that the Nightingale Research Foundation would find this information very useful in its attempt to link hepatitis B vaccination with chronic fatigue syndrome. I wonder how many other medical students, interns and residents, family physicians and specialists who have received the vaccine are suffering as I am. Our voices must be heard!

The measurement of fatigue and chronic fatigue syndrome

Comment in: Chronic fatigue syndrome and heterogeneity. [J R Soc Med. 1992]

 

Fatigue remains as elusive a human experience as ever. At the turn of the century fatigue was almost an obsession of doctors, scientists, writers and even politicians. The scientists believed they could measure it, the doctors they could treat it, the writers describe it, and the politicians prevent it (1). Many confidently expected that fatigue could be eliminated from schools, factories, armies, and even society. That it had to be dealt with was not in doubt, since many authorities believed that if not checked, fatigue, the inevitable consequence of modern life in all its forms, would somehow destroy the nation’s health and its future. Perhaps only the writers achieved their objective (2) – certainly, the descriptions of fatigue and exhaustion in the turn of the century literature, and even in the medical journals, are far richer and detailed than the leaden descriptions which we now encounter.

Unexplained fever and chronic fatigue: abnormal circadian temperature pattern

Abstract:

OBJECTIVES: Standard clinical and biological investigations can be used to determine the origin of persistent and moderate fever in a large number of otherwise asymptomatic patients. However, in a small proportion of cases, isolated fever and fatigue persist despite the absence of detectable organic malfunction. This study was conducted to investigate the circadian thermic pattern in patients with apparently unexplainable fever and chronic fatigue and in those with fever of recognized origin.

METHODS: We recorded central temperature continuously for 24 hours in patients with moderate fever of both unexplained and recognized origin, and in a control group of healthy volunteers. A Fourier series was used for harmonic analysis.

RESULTS: Thermic patterns specific to the three groups were identified by statistical and factorial analysis. The patients with fever of unknown origin and chronic fatigue were clearly characterized in terms of the phase, amplitude of the first (fundamental) harmonic and minimum circadian temperature.

CONCLUSION: The abnormal central temperature pattern in these patients may prove to be an important step in the management of febrile patients.

Chronic fatigue syndrome: a joint paediatric-psychiatric approach

Comment in: Chronic fatigue syndrome: a joint paediatric-psychiatric approach. [Arch Dis Child. 1992]

 

Prolonged fatigue after an apparent viral infection, occurring sporadically or as an epidemic, has been described over the past 50 years. It has been given various names including Royal Free disease (1) and myalgic encephalomyelitis, but the preferred terms in the medical literature have been postviral fatigue syndrome (2) or chronic fatigue syndrome (CFS). (3)

However, the validity of this syndrome as a nosological entity has created a good deal of controversy and remains in doubt. (4) A constellation of symptoms make up the syndrome. There is fatigue of defined onset that is generally reported to follow a viral illness, often an influenza-like illness or an infection of the upper respiratory tract. The patient experiences profound fatigue with the initial illness and then fails to make the expected recovery, with fatigue that can persist over months or years. Fatigue is defined as a subjective sensation, which the patient often describes as tiredness or weariness and that occurs at rest. These patients also report a clear relationship of fatigue to activity. The term fatiguability has been used to describe the greater than normal fatigue that occurs after physical and sometimes after mental exertion in these patients. A great variety of associated symptoms have been described that include increased sleepiness, dizziness, vertigo, headache, difficulty in concentrating, sore throat, muscle weakness, and myalgia. The majority of patients have some emotional symptoms. There can be irritability and anxiety, tearfulness and depression. The fatigue and associated symptoms are of such severity as to impair significantly normal daily activities. There is a remarkable absence of physical signs and physical investigations fail to detect any organic pathology or current infection to account for the symptoms.

Fluctuations in perceived energy and mood among patients with chronic fatigue syndrome

Abstract:

Patients currently suffering or recently recovered from chronic fatigue syndrome (CFS) were compared with each other and with a group of well-matched controls in a study of diurnal variation in levels of perceived mental and physical energy and positive and negative affect.

Patients who were currently ill showed diurnal variation in patterns of energy, with maximum levels being recorded between 10.00 h and 12.00 h which were significantly higher (P < 0.05) than energy levels recorded on rising or retiring. This pattern was similar to the controls but average energy levels at each time point were lower (P < 0.05) among the ill patients.

Recovered patients showed the same pattern, with mean energy levels falling between those of the ill patients and controls. Similar diurnal patterns were found for perceptions of positive, though not negative affect. Correlations between physical and mental energy and between both of these energy variables and positive affect were high (r = 0.75 to 0.85) in both controls and CFS patients. However, correlations with negative affect were low (eg r = -0.10) and non-significant.

Total scores on the Hospital Anxiety and Depression Scale (HAD) were significantly higher (P < 0.05) among patients who were still ill than those who had recovered. Scores on the HAD Depression (but not Anxiety) subscale were also significantly higher among those who were still ill (P < 0.01). These findings may be of value in facilitating programmes of cognitive-behavioural modification intended to aid the recovery of patients with CFS.

Psychosocial management of chronic fatigue syndrome in adolescence

Abstract:

The state of chronic fatigue syndrome (CFS) as abnormal illness behaviour or as biologically determined disease is undecided. The ensuing, often public, debate has confused the community and has led to sharp differences in the therapeutic approach to individual patients. These challenges are compounded when the patient is an adolescent and intergenerational issues enter the picture. Two adolescent cases with different outcomes are presented and the principles of a rehabilitation approach to treatment are outlined which attempt to avoid being drawn into unproductive debates about aetiology.

Chronic tiredness and idiopathic chronic fatigue–a connection?

Abstract:

Evidence is adduced to support the proposal that pathological fatigue is a consequence of impaired capillary blood flow resulting in inadequate oxygen delivery, which is in accordance with physiological concepts of fatigue. Case reports are presented.

Chronic fatigue syndrome

Abstract:

Fatigue is one of the most common complaints among patients seen in the primary care setting. Chronic fatigue syndrome, which has recently been called chronic fatigue immune dysfunction syndrome, is distinctive, with an abrupt onset of symptoms that wax and wane for at least six months.

Usually there is low-grade fever, pharyngitis and tender, but not enlarged, lymph nodes. The fatigue can be disabling and is often made worse by physical activity. Some patients with this disorder have also been found to have highly characteristic immunologic abnormalities.

Treatment can be rewarding and is based on patient education and support, exercise and symptomatic therapies for abnormal sleep patterns, musculoskeletal pain and other symptoms.

Studies on the relationship between chronic fatigue syndrome and Epstein-Barr virus in Japan

Abstract:

Among 1,153 consecutive patients, 22 patients (1.9%) who complained of chronic fatigue for a period of over 6 months without detectable causes were studied.

Ten patients (0.86%) satisfied the criteria of chronic fatigue syndrome (CFS) and were classified to be definite cases of CFS. The other patients were classified as probable cases.

In order to clarify the role of Epstein-Barr virus (EBV) as a cause of CFS, we measured various antibodies for EBV. The definite cases had significantly higher titers of early antigen complex (EA)-IgG than both the probable cases and controls.

We proposed the EA-IgG/EBNA ratio as the indicator of activation of EBV and attempted to estimate the degree of fatigue by the EA-IgG/EBNA ratio. The highest ratio value (16.0) of the 22 patients ratios was the most serious case. In general, the ratio correlated with the degree of fatigue. Based on these results, it was concluded that a relationship does exist between CFS and EBV.

Chronic fatigue syndrome. A review from the general practice perspective

Abstract:

There is no doubt that the chronic fatigue syndrome exists. It is a condition that is debilitating and of unknown cause. Research into chronic fatigue syndrome demonstrates possible psychiatric or organic causes. The truth may be somewhere in between. Evidence for the existence of an ongoing chronic infection is now not convincing. Treatment should be based on supportive counselling, explanation, psychiatric help (both pharmacological and non pharmacological) and a graded programme of increased activity with the eventual aim of resumption of full functioning.
