Sympathomimetic amine therapy may improve refractory gastroparesis similar to its effect on chronic pelvic pain--case report.

Boimel, P, Check, J H, Katsoff, D·Clinical and experimental obstetrics & gynecology·2007

This case report describes one patient with ME/CFS who had severe stomach emptying problems (gastroparesis) that didn't respond to standard treatments. When she was given a stimulant medication called dextroamphetamine, her stomach symptoms improved significantly and stayed better for at least eight months. The authors suggest this type of medication might help some people with refractory gastroparesis, similar to how it may help other ME/CFS-related symptoms.

Autonomic Nervous System

Normalization of the increased translocation of endotoxin from gram negative enterobacteria (leaky gut) is accompanied by a remission of chronic fatigue syndrome.

Maes, Michael, Coucke, Francis, Leunis, Jean-Claude·Neuro endocrinology letters·2007

This study describes a teenage girl with ME/CFS who had damage to her gut lining, allowing bacterial toxins to leak into her bloodstream. When she was treated with antioxidants, dietary changes to repair her gut, and immune support therapy, the leaky gut improved and her ME/CFS symptoms disappeared. The findings suggest that gut damage may play a role in some ME/CFS cases.

[School phobia and childhood chronic fatigue syndrome (CCFS)].

Tomoda, Akemi·Nihon rinsho. Japanese journal of clinical medicine·2007

This review examines childhood chronic fatigue syndrome (CCFS), a serious condition where children experience extreme tiredness that cannot be explained by other medical or mental health problems. Children with CCFS often struggle with memory and concentration, sleep problems, and symptoms related to their nervous system. The authors suggest that CCFS may involve changes in how the brain functions, which could explain why patients experience fatigue, thinking difficulties, and memory problems.

[Fibromyalgia and chronic fatigue syndrome in children and adolescents].

Galanopoulos, Ng, Kampakis, Gp, Ladopoulou, Kf·Psychiatrike = Psychiatriki·2007

This review discusses fibromyalgia and chronic fatigue syndrome (ME/CFS) in children and teenagers, noting that both conditions are fairly common in this age group. Patients with these conditions experience widespread muscle pain, exhaustion, depression, headaches, and sleep problems that can significantly impact school, family life, and overall development. The authors emphasize that early diagnosis and treatment combining medication, physical therapy, and psychological support are important for helping young people manage these conditions.

Rehabilitation of decreased motor performance in patients with chronic fatigue syndrome: should we treat low effort capacity or reduced effort tolerance?

Van Houdenhove, B, Verheyen, L, Pardaens, K et al.·Clinical rehabilitation·2007

This paper proposes a new way to think about why people with ME/CFS have reduced physical ability. The authors suggest there may be two different problems: some patients may have low energy capacity (their bodies can't produce enough energy), while others may have reduced effort tolerance (their nervous system tells them to stop before their body actually reaches its limit). Understanding which problem a patient has could help doctors choose better treatments.

Post-Exertional Malaise

The hypothalamo-pituitary-adrenal axis in chronic fatigue syndrome and fibromyalgia syndrome.

Tanriverdi, F, Karaca, Z, Unluhizarci, K et al.·Stress (Amsterdam, Netherlands)·2007

This review examines how the stress response system (called the HPA axis) works differently in people with ME/CFS and fibromyalgia. The HPA axis is normally responsible for managing how your body responds to stress. Most studies show that in these conditions, the system is underactive and produces lower levels of cortisol (a stress hormone), though some studies have found different results.

Endocrine Disruption

Hyperventilation in patients with chronic fatigue syndrome: the role of coping strategies.

Bogaerts, Katleen, Hubin, Morgane, Van Diest, Ilse et al.·Behaviour research and therapy·2007

This study looked at how people with ME/CFS breathe differently depending on how they mentally cope with their illness. Researchers found that when patients imagined resisting or fighting against their illness, their breathing changed in ways that made their symptoms worse. In contrast, when patients imagined accepting their illness, their breathing stayed more stable and symptoms improved. This suggests that our psychological response to ME/CFS may directly affect how our body breathes and which symptoms we experience.

Fibromyalgia and overlapping disorders: the unifying concept of central sensitivity syndromes.

Yunus, Muhammad B·Seminars in arthritis and rheumatism·2007

This paper proposes that fibromyalgia, irritable bowel syndrome, chronic fatigue syndrome, and certain headaches may all share a common underlying problem: the nervous system becomes too sensitive to pain and other signals. Rather than being separate diseases, they might be related conditions caused by similar changes in how the brain and body communicate, combined with stress and emotional factors.

Pain and Sensitization

E3 PreliminaryReviewPEM not requiredReview-Narrative

[Overview of chronic fatigue syndrome focusing on prevalence and diagnostic criteria].

Kuratsune, Hirohiko·Nihon rinsho. Japanese journal of clinical medicine·2007

This review examines ME/CFS as a real medical condition affecting the nervous system, immune system, and stress response. While researchers have found many different abnormalities in ME/CFS patients—including viral reactivation, immune problems, and chemical imbalances in the brain—no single cause has been identified in everyone with the condition. The authors suggest that ME/CFS likely results from a combination of genetic factors and life stress that disrupts how the body's immune and hormone systems work together.

The thoughts and methods for clinical research on acupuncture treatment of chronic fatigue syndrome.

Yao, Renmin·Journal of traditional Chinese medicine = Chung i tsa chih ying wen pan·2007

This paper presents acupuncture treatment guidelines for chronic fatigue syndrome (ME/CFS), focusing on how acupuncture might restore balance to the body's energy systems according to traditional Chinese medicine. The authors discuss important considerations like which patients are most suitable for treatment, which acupuncture points to use, and how to measure whether the treatment is working.

[Overview of medical treatment and management of chronic fatigue syndrome].

Yoshihara, Kazufumi, Kubo, Chiharu·Nihon rinsho. Japanese journal of clinical medicine·2007

This paper presents a comprehensive approach to treating ME/CFS that combines different types of therapies tailored to individual patients. The main treatments discussed include structured exercise programs (done gradually), lifestyle changes, and sometimes medications or mental health support when needed. The authors emphasize that doctors should carefully monitor patients throughout treatment and adjust their plan based on how well it's working.

An experimental study of the influence of individual participant characteristics on formal consensus development.

Carpenter, James, Hutchings, Andrew, Raine, Rosalind et al.·International journal of technology assessment in health care·2007

This study looked at how different types of doctors and healthcare workers rate whether psychological treatments are appropriate for ME/CFS and other chronic conditions. Researchers had 346 people in 20 groups review mental health treatments and rate how suitable they were, testing whether factors like the doctors' specialty, age, and sex changed their opinions.

Fibromylagia, chronic fatigue, and adult attention deficit hyperactivity disorder in the adult: a case study.

Young, Joel L, Redmond, Judith C·Psychopharmacology bulletin·2007

This study looked at patients who came to a psychiatry clinic with ADHD symptoms and also had unexplained tiredness and widespread pain—conditions similar to ME/CFS or fibromyalgia. When doctors treated the ADHD with medication, some patients noticed their fatigue and pain improved along with their attention problems. The researchers suggest this might mean these conditions involve how the brain processes information rather than problems in muscles and joints.

Cognitive Impairment

[Chronic fatigue syndrome and herpesvirus reactivation].

Kondo, Kazuhiro·Nihon rinsho. Japanese journal of clinical medicine·2007

This study looked at whether two common viruses that hide dormant in our bodies (HHV-6 and HHV-7) wake up and become active during fatigue. Researchers found that healthy people shed more HHV-6 in their saliva when tired from work, but ME/CFS patients did not show this pattern. However, HHV-7 did increase in both groups, suggesting these viruses might be useful markers to measure fatigue objectively.

Violence, stress, and somatic syndromes.

Crofford, Leslie J·Trauma, violence & abuse·2007

This review article examines how experiences of violence and stress may trigger or worsen conditions like ME/CFS, fibromyalgia, and irritable bowel syndrome—illnesses that involve pain, exhaustion, mood changes, memory problems, and sleep issues. The authors explain that stress affects the brain and body's hormone and nervous system function, which may make people more vulnerable to developing these conditions. Understanding this connection could help us recognize how violence exposure affects long-term health.

Increased serum IgM antibodies directed against phosphatidyl inositol (Pi) in chronic fatigue syndrome (CFS) and major depression: evidence that an IgM-mediated immune response against Pi is one factor underpinning the comorbidity between both CFS and depression.

Maes, Michael, Mihaylova, Ivanka, Leunis, Jean-Claude·Neuro endocrinology letters·2007

This study found that people with ME/CFS and depression have higher levels of specific immune proteins (IgM antibodies) that attack a substance called phosphatidyl inositol in their blood compared to healthy people. These antibody levels were linked to fatigue and depression symptoms, suggesting that an abnormal immune response against this substance might contribute to both conditions.

[Spectroscopic diagnosis of chronic fatigue syndrome by multivariate analysis of visible and near-infrared spectra].

Sakudo, Akikazu, Kuratsune, Hirohiko, Hakariya, Yukiko et al.·Nihon rinsho. Japanese journal of clinical medicine·2007

Researchers tested whether a special light-based technology called visible and near-infrared spectroscopy could help diagnose ME/CFS by analyzing blood samples and skin. The technique uses different wavelengths of light to detect patterns that might differ between people with ME/CFS and healthy people. Early results showed the method could correctly identify about 70-80% of cases, suggesting this approach might one day offer a quick, non-invasive way to help diagnose the condition.

Díaz-Caneja Greciano, A, Rodríguez Sosa, J T, Aguilera Albesa, S et al.·Anales de pediatria (Barcelona, Spain : 2003)·2007

This report describes a 15-year-old girl diagnosed with ME/CFS (chronic fatigue syndrome), a condition that causes severe tiredness and lack of energy without an obvious physical cause. The doctors emphasize that ME/CFS should be considered when young people have chronic fatigue along with other symptoms but medical tests don't reveal why. Treatment focused on rehabilitation with cognitive behavioral therapy (talking therapy to address thoughts and behaviors) combined with a gradual, structured increase in activity levels.

[Sleep disturbance in chronic fatigue syndrome].

Kumano-go, Takayuki, Adachi, Hiroyoshi, Sugita, Yoshiro·Nihon rinsho. Japanese journal of clinical medicine·2007

This study looked at sleep problems in ME/CFS patients using a special laser device to measure blood flow patterns during sleep. The researchers found that different ME/CFS patients showed different types of abnormal sleep patterns, suggesting that ME/CFS may actually be several different conditions rather than one single illness. Sleep disturbances like insomnia, oversleeping, and irregular sleep-wake cycles are common in ME/CFS.

The association between experimental and clinical pain measures among persons with fibromyalgia and chronic fatigue syndrome.

Geisser, Michael E, Gracely, Richard H, Giesecke, Thorsten et al.·European journal of pain (London, England)·2007

Researchers tested whether laboratory pain tests (using heat and pressure) could predict the pain people with fibromyalgia and ME/CFS experience in daily life. They found that pressure-based tests were better predictors of real-world pain than heat tests, suggesting that pressure stimulation may be a more useful research tool for studying pain in these conditions.
