Genetic instability and fragmentation of a stealth viral genome.

Martin, W J·Pathobiology : journal of immunopathology, molecular and cellular biology·1996

Researchers studied a virus found in a patient with chronic fatigue syndrome (ME/CFS) and discovered it has an unusual fragmented structure with many genetic errors. The virus appears to be related to cytomegalovirus but is much less organized, splitting into small pieces rather than staying intact. These genetic defects in the virus might actually help the body fight it off and recover from illness.

E3 PreliminaryTrialPEM not requiredRCT

Interferon alfa-2b versus no maintenance therapy during the plateau phase in multiple myeloma: a randomized study. Cooperative Study Group.

Westin, J, Rödjer, S, Turesson, I et al.·British journal of haematology·1995

This study tested whether a drug called interferon alfa-2b could help multiple myeloma patients (a type of blood cancer) stay in remission longer after their initial treatment. Patients who received interferon stayed in remission for about 14 months compared to 6 months for those who didn't, but both groups lived about the same length of time overall.

E3 PreliminaryBehavioralPEM not requiredObservational

Chronic fatigue syndrome: a cognitive approach.

Surawy, C, Hackmann, A, Hawton, K et al.·Behaviour research and therapy·1995

This study looked at what ME/CFS patients were thinking and believing about their symptoms, and how these thoughts might play a role in the condition. Researchers listened to patients' own descriptions of their fatigue and the thoughts that came with it, then tested whether a talking therapy called cognitive behavioural therapy (CBT) could help. The study suggests that the way patients think about their symptoms might be part of what keeps them sick.

E3 PreliminaryCohortPEM not required

Neuroretinitis, aseptic meningitis, and lymphadenitis associated with Bartonella (Rochalimaea) henselae infection in immunocompetent patients and patients infected with human immunodeficiency virus type 1.

Wong, M T, Dolan, M J, Lattuada, C P et al.·Clinical infectious diseases : an official publication of the Infectious Diseases Society of America·1995

This study examined patients infected with Bartonella henselae, a bacteria spread by cat scratches and bites, which can cause lymph node swelling, eye inflammation, fever, and meningitis (brain membrane inflammation). Researchers found 23 patients with this infection, many of whom had been exposed to cats. Notably, one patient presented with a chronic fatigue syndrome-like illness, suggesting this bacterial infection might sometimes resemble ME/CFS symptoms.

E3 PreliminaryReviewPEM not requiredReview-Narrative

Corticotropin releasing hormone in the pathophysiology of melancholic and atypical depression and in the mechanism of action of antidepressant drugs.

Gold, P W, Licinio, J, Wong, M L et al.·Annals of the New York Academy of Sciences·1995

This research examines how the stress hormone system works differently in people with depression and chronic fatigue syndrome. The study found that while some people with depression have too much cortisol (a stress hormone), others—particularly those with fatigue-related conditions—may have too little activity in the part of the brain that normally triggers this hormone. This suggests that different types of depression and fatigue conditions might involve different problems with the body's stress response system.

Endocrine Disruption

E3 PreliminaryMechanismPEM not requiredCross-Sectional

The disease associations of the antibody response against the Epstein-Barr virus transactivator protein ZEBRA can be separated into different epitopes.

Tedeschi, R, Foong, Y T, Cheng, H M et al.·The Journal of general virology·1995

This study looked at antibody patterns against a specific EBV protein called ZEBRA, which becomes active when the virus 'wakes up' from dormancy. Researchers found that different parts of this protein trigger antibodies in different diseases—some patterns were more common in people with nasopharyngeal cancer, others in people with infectious mononucleosis, and some in people with chronic fatigue syndrome. This suggests that the type of EBV reactivation may differ depending on the illness someone has.

Immune System

E3 PreliminaryReviewPEM not requiredReview-Narrative

Are cytokines associated with neuropsychiatric syndromes in humans?

Hickie, I, Lloyd, A·International journal of immunopharmacology·1995

This paper suggests that immune molecules called cytokines—which your body produces during infections or inflammation—may affect your brain and behavior in ways that look like psychiatric symptoms such as depression, fatigue, loss of appetite, and difficulty thinking clearly. The authors review evidence from various illnesses where these immune-related behavioral changes happen together, including ME/CFS, and propose that cytokines may be the biological link between immune activation and these symptoms.

[Clinical aspects and neurologic expert assessment in sequelae of whiplash injury to the cervical spine].

Jenzer, G·Der Nervenarzt·1995

This review examined whiplash injuries to the neck and the long-term complications some patients develop, called chronic whiplash syndrome. The authors found that whiplash injuries can cause a complex mix of symptoms similar to those seen in chronic fatigue syndrome and fibromyalgia, making diagnosis challenging. Most people recover well from whiplash, though some experience prolonged difficulties.

Diagnostics

E3 PreliminaryCohortPEM not requiredCross-Sectional

[Auditory brain stem evoked potentials in the evaluation of chronic fatigue syndrome].

Bianchedi, M, Croce, A, Moretti, A et al.·Acta otorhinolaryngologica Italica : organo ufficiale della Societa italiana di otorinolaringologia e chirurgia cervico-facciale·1995

Researchers tested a special hearing test on people with ME/CFS to see if it could find differences in how their brainstem (the lower part of the brain) processes sound. They used two types of sound frequencies—slow and fast clicking sounds—while measuring brain electrical activity. The fast clicking test found unusual patterns in about 64% of people with confirmed ME/CFS, but not in people without ME/CFS, suggesting this test might help identify the condition.

E3 PreliminaryMechanismPEM not requiredMechanistic

Acute encephalopathy induced in cats with a stealth virus isolated from a patient with chronic fatigue syndrome.

Martin, W J, Glass, R T·Pathobiology : journal of immunopathology, molecular and cellular biology·1995

Researchers isolated a virus from a ME/CFS patient and injected it into cats to see what would happen. The cats developed serious neurological illness, and examination of their brain tissue showed viral particles and cell damage. This suggests that a particular type of virus might play a role in ME/CFS-related brain symptoms.

E3 PreliminaryGuidelinePEM not requiredGuideline

Chronic fatigue syndrome: current perspectives on evaluation and management.

Hickie, I B, Lloyd, A R, Wakefield, D·The Medical journal of Australia·1995

This guideline helps doctors evaluate and treat ME/CFS by reviewing what we know about the condition. The authors found that while many medical and psychological factors can affect recovery, no single infection has been proven to cause ME/CFS. Treatment works best when doctors address all aspects of a patient's health—physical, mental, and social—rather than focusing on just one area.

Diagnostics

E3 PreliminaryCohortPEM not requiredCase-Control

Chronic active Epstein-Barr virus disease in a case of persistent polyclonal B-cell lymphocytosis.

Mitterer, M, Pescosta, N, Fend, F et al.·British journal of haematology·1995

This report describes one patient who had an unusual blood disorder involving too many B cells (immune cells) along with symptoms resembling chronic fatigue syndrome, including persistent tiredness and recurring skin rashes. Testing showed the patient had a chronic active Epstein-Barr virus (EBV) infection with the virus actively replicating in their blood cells. The researchers suggest that persistent EBV replication may play a role in developing this lymphoproliferative disorder.

Immune System

E3 PreliminaryReviewPEM not requiredReview-Narrative

[Chronic fatigue syndrome--a review of the literature].

Hamre, H J·Tidsskrift for den Norske laegeforening : tidsskrift for praktisk medicin, ny raekke·1995

ME/CFS is a real medical condition that causes extreme tiredness, low-grade fevers, sore throats, and pain in joints and muscles, often starting after a flu-like illness. Exercise makes symptoms significantly worse. While doctors don't yet have a single blood test to diagnose it, research shows patients may have problems with brain blood flow, immune system issues, and mitochondrial (cellular energy) abnormalities.

Immune SystemPost-Exertional Malaise

E3 PreliminaryMechanismPEM not requiredMechanistic

African green monkey origin of the atypical cytopathic 'stealth virus' isolated from a patient with chronic fatigue syndrome.

Martin, W J, Ahmed, K N, Zeng, L C et al.·Clinical and diagnostic virology·1995

Researchers found a virus in a chronic fatigue syndrome patient that resembled cytomegalovirus but had unusual characteristics. By comparing the virus's genetic code to known viruses in databases, they discovered it was most similar to a virus found in African green monkeys, suggesting this may be its original source.

Chronic fatigue syndrome.

Krilov, L R·Pediatric annals·1995

This 1995 study examined chronic fatigue syndrome (ME/CFS) in children by comparing cases with controls. The research aimed to better understand how this condition affects young patients. As a case-control study, it looked at differences between children who had ME/CFS and those who didn't to identify important patterns.

E3 PreliminaryCohortPEM unclearCase-Control

Unusual pattern of mitochondrial DNA deletions in skeletal muscle of an adult human with chronic fatigue syndrome.

Zhang, C, Baumer, A, Mackay, I R et al.·Human molecular genetics·1995

This 1995 study examined muscle tissue from one adult patient with ME/CFS and found an unusual pattern of damaged mitochondrial DNA (the energy-producing structures in our cells). The researchers compared this patient's muscle cells to control samples and discovered deletions—missing pieces—in the mitochondrial DNA that weren't typically seen in healthy people. This finding suggested that energy production problems in muscle cells might contribute to the fatigue experienced by ME/CFS patients.

E3 PreliminaryReviewPEM unclearReview-Narrative

The pathogenesis of chronic pain and fatigue syndromes, with special reference to fibromyalgia.

Clauw, D J·Medical hypotheses·1995

This paper reviews what doctors and researchers knew in 1995 about fibromyalgia and similar conditions that cause chronic pain and tiredness. The authors noticed that fibromyalgia overlaps significantly with chronic fatigue syndrome, migraines, irritable bowel syndrome, and mood disorders, suggesting these conditions may share common underlying causes rather than being completely separate diseases.

Vestibular function test anomalies in patients with chronic fatigue syndrome.

Ash-Bernal, R, Wall, C, Komaroff, A L et al.·Acta oto-laryngologica·1995

Many people with ME/CFS experience dizziness and balance problems, but doctors weren't sure where these problems originated in the body. This study tested the balance and inner ear function of 11 ME/CFS patients using specialized equipment and found several abnormalities—particularly difficulty with tests that rely heavily on the inner ear and brain working together. The pattern of results suggested the problem may be in how the brain processes balance signals rather than damage to the inner ear itself.

'Repetitive strain injury': from Australia to the UK.

Reilly, P A·Journal of psychosomatic research·1995

In the 1980s, Australia experienced a widespread outbreak of upper limb pain that didn't fit standard medical diagnoses. The UK is now seeing a similar epidemic. This study examines whether the condition is truly caused by workplace activities or whether psychological and social factors play a larger role, similar to what happens in chronic fatigue syndrome.

Is neurally mediated hypotension an unrecognised cause of chronic fatigue?

Rowe, P C, Bou-Holaigah, I, Kan, J S et al.·Lancet (London, England)·1995

This study looked at whether a condition called neurally mediated hypotension—where blood pressure drops suddenly when standing up—might be causing chronic fatigue in some patients. Researchers tested seven teenagers with severe fatigue using a tilt-table test (which gradually tilts the body upright) and found that all seven experienced significant drops in blood pressure. Four of these patients improved when treated with specific heart medications, suggesting this condition may contribute to some cases of ME/CFS.
