An under-active or over-active internal world? An exploration of parallel dynamics within psyche and soma, and the difficulty of internal regulation, in patients with Chronic Fatigue Syndrome and Myalgic Encephalomyelitis.

Driver, Christine·The Journal of analytical psychology·2005

This study examines how the mind and body become deeply connected in people with ME/CFS, making it hard to regulate both emotions and physical symptoms. Through detailed analysis of one patient's therapy, the researcher explores how early experiences with parents may affect how the body and mind communicate and function together in ME/CFS.

Psychometric properties of the CDC Symptom Inventory for assessment of chronic fatigue syndrome.

Wagner, Dieter, Nisenbaum, Rosane, Heim, Christine et al.·Population health metrics·2005

Researchers created and tested a new questionnaire called the CDC CFS Symptom Inventory to help measure the many different symptoms that people with ME/CFS experience—not just fatigue, but also other important symptoms like problems with memory, sleep, and pain. They gave this questionnaire to 164 people (some with ME/CFS, some with other illnesses, and some without fatigue) and found that the questionnaire reliably distinguished people with ME/CFS from others and worked well when compared to existing fatigue measurement tools.

Search for disease-specific cardiovascular reactivity patterns: developing the methodology.

Naschitz, Jochanan E, Rozenbaum, Michael, Fields, Madeline et al.·Clinical science (London, England : 1979)·2005

Researchers developed new methods to detect specific patterns in how the body's heart rate and blood pressure respond to physical stress (tilting upright) in people with familial Mediterranean fever (FMF). They found that people with FMF show distinctive cardiovascular responses that can be measured and used to help identify the condition. The study shows this approach might also work for other diseases, including ME/CFS.

Supporting people with severe myalgic encephalomyelitis.

Crowhurst, Greg·Nursing standard (Royal College of Nursing (Great Britain) : 1987)·2005

This article helps nurses better understand ME/CFS, a serious condition that is often misunderstood by healthcare providers. The author describes the main symptoms people experience and discusses how healthcare services can support patients. The article emphasizes that ME/CFS is a real physical illness that needs more research to help doctors and nurses care for people with it properly.

In chronic fatigue syndrome, the decreased levels of omega-3 poly-unsaturated fatty acids are related to lowered serum zinc and defects in T cell activation.

Maes, Michael, Mihaylova, Ivana, Leunis, Jean-Claude·Neuro endocrinology letters·2005

This study found that people with ME/CFS have lower levels of omega-3 fatty acids (healthy fats found in fish) and higher levels of other types of fats compared to healthy people. These imbalances were linked to lower zinc levels and problems with immune cells called T cells, which help fight infection. The researchers suggest that omega-3 supplements might help ME/CFS patients.

Urinary electrophoretic profiles from chronic fatigue syndrome and chronic fatigue syndrome/fibromyalgia patients: a pilot study for achieving their normalization.

Casado, Begoña, Zanone, Chiara, Annovazzi, Laura et al.·Journal of chromatography. B, Analytical technologies in the biomedical and life sciences·2005

Researchers collected urine samples from people with ME/CFS, people with ME/CFS plus fibromyalgia, and healthy controls to look for chemical differences. Using a specialized lab technique called electrophoresis, they found that the urine samples from people with these conditions showed distinct patterns of chemicals compared to healthy people. These patterns might potentially be used as biological markers to help identify and understand these illnesses.

2',5'-Oligoadenylate size is critical to protect RNase L against proteolytic cleavage in chronic fatigue syndrome.

Frémont, Marc, El Bakkouri, Karim, Vaeyens, Freya et al.·Experimental and molecular pathology·2005

In ME/CFS, immune cells produce abnormal levels of proteins involved in fighting viral infections. This study found that a protective molecule called 2-5A can shield a key antiviral protein (RNase L) from being broken down by inflammatory enzymes. However, in ME/CFS patients, cells tend to produce smaller versions of 2-5A, which cannot provide this protection, leading to the accumulation of damaged RNase L protein.

Characterization of virus isolates by particle-associated nucleic acid PCR.

Stang, Alexander, Korn, Klaus, Wildner, Oliver et al.·Journal of clinical microbiology·2005

Researchers developed a new laboratory method called PAN-PCR that can identify viruses in patient samples even when standard tests fail to detect them. This technique works by finding viral genetic material protected inside virus particles and then copying and analyzing it. As a test case, they used this method on a mouth sample from a ME/CFS patient and successfully identified herpes simplex virus type 1, which had been missed by conventional testing.

Impairments of the 2-5A synthetase/RNase L pathway in chronic fatigue syndrome.

Nijs, Jo, De Meirleir, Kenny·In vivo (Athens, Greece)·2005

This study looks at a specific immune system pathway called the 2-5A synthetase/RNase L pathway that may be broken in ME/CFS patients. Researchers found that in ME/CFS, this pathway is overactive but also working improperly—it's being broken down into unusual pieces instead of functioning normally. This abnormal pathway appears connected to reduced natural killer cell function and problems with how cells die when they should.

Chronic fatigue syndrome: it's tiring not knowing much--an in-depth review for occupational health professionals.

Glozier, N·Occupational medicine (Oxford, England)·2005

This is a detailed review article about ME/CFS written for occupational health professionals. The article examines what is known about ME/CFS, including how it affects people's ability to work, and highlights the significant gaps in our understanding of the condition. The main message is that ME/CFS remains poorly understood, which makes it difficult for doctors, employers, and patients to manage effectively.

[Diagnosing asthenia and chronic fatigue syndrome].

Aslangul, Elisabeth, Le Jeunne, Claire·La Revue du praticien·2005

This article discusses how doctors can distinguish between general tiredness (asthenia) and ME/CFS, which is a serious long-term illness characterized by severe fatigue that doesn't improve with rest. The authors review the clinical features and diagnostic approaches that help healthcare providers identify ME/CFS in their patients. Understanding these differences is important so patients receive appropriate diagnosis and care.

The clinical course of interstitial pneumonia alias chronic fatigue syndrome under the control of megadose vitamin C infusion system with dehydroepiandrosterone-cortisol annex.

Kodama, Mitsuo, Kodama, Toshiko·International journal of molecular medicine·2005

This study describes a treatment approach combining high-dose vitamin C infusions with hormonal supplements (DHEA and cortisol) in patients with interstitial pneumonia, which the authors propose may be related to ME/CFS. Over 9 years, the researchers tracked whether this treatment reduced flare-ups and prevented complications like cancer and depression. The treatment appeared to help reduce active pneumonia symptoms, though it did not prevent long-term scarring of the lungs.

Practitioner review: chronic fatigue syndrome in childhood.

Elena Garralda, M, Chalder, Trudie·Journal of child psychology and psychiatry, and allied disciplines·2005

This review examines how ME/CFS appears in children and teenagers and discusses the best ways to help them recover. The authors found that ME/CFS in young people is often triggered by infections and can be diagnosed using the same criteria as in adults. They recommend a family-based approach using cognitive behavior therapy and gradually increasing activity, which has shown promise in helping children regain function.

Green tea extract and catechin ameliorate chronic fatigue-induced oxidative stress in mice.

Singal, Anjali, Kaur, Surinder, Tirkey, Naveen et al.·Journal of medicinal food·2005

This study tested whether green tea extract and a compound found in green tea called catechin could help reduce fatigue in mice that were forced to swim repeatedly. The researchers found that these treatments reduced signs of fatigue and lowered harmful chemical damage (oxidative stress) in the brains of fatigued mice, suggesting they might be helpful for people with ME/CFS.

A new view on hypocortisolism.

Fries, Eva, Hesse, Judith, Hellhammer, Juliane et al.·Psychoneuroendocrinology·2005

Some people with ME/CFS, fibromyalgia, and PTSD have abnormally low levels of cortisol, a stress hormone their body normally produces. This review suggests that this low cortisol may develop after the body's stress system works overtime for a long time. Interestingly, while low cortisol contributes to symptoms like fatigue, pain, and stress sensitivity, it may also provide some protective benefits to the body.

Aetiology and pathogenesis of chronic fatigue syndrome: a review.

Mihrshahi, Robin, Beirman, Robyn·The New Zealand medical journal·2005

This review article examines what scientists currently understand about what causes ME/CFS and how the illness develops. The authors looked at research across four main areas: infections, immune system problems, hormonal and nervous system imbalances, and mental health factors. They suggest that ME/CFS likely results from a combination of these factors rather than a single cause.

Pathogenesis of parvovirus B19 infection: host gene variability, and possible means and effects of virus persistence.

Kerr, J R·Journal of veterinary medicine. B, Infectious diseases and veterinary public health·2005

This study examined how parvovirus B19 might trigger chronic fatigue syndrome (CFS) in some people. Researchers found that patients with prolonged symptoms after B19 infection had high levels of inflammatory chemicals in their blood, and identified certain genetic variations that may make some people more susceptible to developing CFS after B19 infection. They also discovered that the virus may persist in the body by hiding in human genes, and found that people carrying B19 virus DNA had altered expression of several genes involved in cell structure and immune function.

Pain in patients with chronic fatigue syndrome: does nitric oxide trigger central sensitisation?

Nijs, Jo, Van de Velde, Bart, De Meirleir, Kenny·Medical hypotheses·2005

This study proposes a theory about why ME/CFS patients experience widespread pain. The researchers suggest that a molecule called nitric oxide may cause the central nervous system (the brain and spinal cord) to become overly sensitive, amplifying pain signals throughout the body. They propose that viral infections or other pathogens associated with ME/CFS may trigger this chain reaction, and that behaviors like catastrophizing or avoiding activity may either contribute to or result from this heightened sensitivity.

Drug targets in stress-related disorders.

Covelli, Vito, Passeri, Maria Elena, Leogrande, Domenica et al.·Current medicinal chemistry·2005

This review examines how stress affects both the nervous and immune systems, and explores potential drug treatments for stress-related disorders. The authors discuss how the body's stress response systems can trigger or worsen conditions like chronic fatigue syndrome (CFS), and suggest that medicines targeting immune cell activity and inflammatory chemicals may help. They found that CFS patients have different immune patterns compared to depressed patients, which could guide future treatment approaches.

[Significance of the chronic fatigue syndrome in rehabilitation medicine--status and perspectives].

Gutenbrunner, C, Linden, M, Gerdes, N et al.·Die Rehabilitation·2005

This paper discusses how chronic fatigue and exhaustion affect people undergoing rehabilitation for various medical conditions. The authors reviewed how fatigue is defined, how often it occurs in different patient groups (from 50-90% depending on the condition), and whether rehabilitation can help improve it. They suggest that fatigue symptoms do improve somewhat with rehabilitation, though some symptoms can remain.
