Fatigue after spinal cord injury.

Barat, M, Dehail, P, de Seze, M·Annales de readaptation et de medecine physique : revue scientifique de la Societe francaise de reeducation fonctionnelle de readaptation et de medecine physique·2006

This review looked at fatigue that develops after spinal cord injury and found two main types: one caused by muscle weakness and paralysis from nerve damage, and another that develops over time and resembles conditions like chronic fatigue syndrome. The authors suggest that exercise programs and electrical stimulation of muscles might help reduce this fatigue and improve quality of life for people with spinal cord injuries.

Beneficial effect of brewers' yeast extract on daily activity in a murine model of chronic fatigue syndrome.

Takahashi, Takashi, Yu, Fei, Zhu, Shi-Jie et al.·Evidence-based complementary and alternative medicine : eCAM·2006

Researchers gave mice a brewer's yeast extract to see if it could help restore activity levels in a mouse model of ME/CFS. Mice treated with the yeast extract showed significantly better activity levels compared to untreated mice, and the treated mice also had better survival rates. The study suggests that brewer's yeast extract may help by adjusting immune system responses that become imbalanced in ME/CFS.

Antidepressant-like activity of a Kampo (Japanese herbal) medicine, Koso-san (Xiang-Su-San), and its mode of action via the hypothalamic-pituitary-adrenal axis.

Ito, N, Nagai, T, Yabe, T et al.·Phytomedicine : international journal of phytotherapy and phytopharmacology·2006

This study tested whether Koso-san, a traditional Japanese herbal medicine, could help reduce depression-like symptoms in mice exposed to stress. Mice given Koso-san showed improved behavior in stress tests, and the herb appeared to normalize stress hormone systems in their brains that were overactive due to the stress exposure.

Gene expression profile of empirically delineated classes of unexplained chronic fatigue.

Carmel, Liran, Efroni, Sol, White, Peter D et al.·Pharmacogenomics·2006

Researchers examined genes in blood samples from 111 women with unexplained chronic fatigue to see if different types of fatigue had different gene patterns. They used computer analysis to identify specific genes that were active or inactive in different fatigue groups. They found that certain genes were consistently different between fatigued and healthy people, while other genes only differed in specific fatigue subgroups.

Illness Beliefs in Chronic Fatigue Syndrome: A Study Involving Affected Adolescents and their Parents.

Richards, Jo, Chaplin, Robert, Starkey, Caroline et al.·Child and adolescent mental health·2006

This study asked 21 young people with ME/CFS and their parents about what they thought caused the illness and how they managed it. Most people believed the illness started from an infection, while fewer thought it was psychological. Many found that resting and reducing activity helped manage symptoms. The study highlights that doctors should listen carefully to what patients and families believe about ME/CFS before deciding on treatment.

E3 PreliminaryCohortPEM not requiredObservational

Causes of death among patients with chronic fatigue syndrome.

Jason, Leonard A, Corradi, Karina, Gress, Sara et al.·Health care for women international·2006

This study looked at 166 people with ME/CFS who had passed away to understand what caused their deaths. The researchers found that heart failure, suicide, and cancer were the three leading causes, together accounting for nearly 60% of deaths. Notably, people with ME/CFS who died from cancer or suicide were much younger—in their late 30s to mid-40s—compared to people in the general population who died from these same causes.

Contribution of gender to pathophysiology and clinical presentation of IBS: should management be different in women?

Ouyang, Ann, Wrzos, Helena F·The American journal of gastroenterology·2006

This review article examines why irritable bowel syndrome (IBS)—a condition causing digestive discomfort—affects more women than men. The authors discuss how biological sex differences, hormones, and gender roles may influence who develops IBS and how severe their symptoms are. They suggest that while men and women are treated similarly for IBS, paying attention to stress and gender-specific factors might improve care.

Four problems with the clinical control of interstitial pneumonia, or chronic fatigue syndrome, using the megadose vitamin C infusion system with dehydroepiandrosterone-cortisol annex.

Kodama, Mitsuo, Kodama, Toshiko·In vivo (Athens, Greece)·2006

This study describes a clinic's experience treating patients with interstitial pneumonia (a lung condition) using high-dose vitamin C infusions combined with hormones and antibiotics since 1996. The authors discuss four main challenges they encountered: deciding whether to continue treatment when patients seemed stable, dealing with bacteria becoming resistant to antibiotics, observing bone marrow damage in one patient, and noting one patient developed breast cancer during treatment.

Gene expression profile exploration of a large dataset on chronic fatigue syndrome.

Fang, Hong, Xie, Qian, Boneva, Roumiana et al.·Pharmacogenomics·2006

Researchers studied the genes that are turned on or off differently in people with ME/CFS compared to healthy controls. They looked at blood samples from 167 people and used computer analysis to identify 24 key genes and 11 biological pathways that appear to be involved in ME/CFS. These genes are involved in immune function, cell communication, and nerve activity—areas that scientists already suspect play a role in the illness.

Fibromyalgia, infection and vaccination: two more parts in the etiological puzzle.

Ablin, Jacob N, Shoenfeld, Yehuda, Buskila, Dan·Journal of autoimmunity·2006

This review examines whether infections and vaccinations might trigger fibromyalgia and related conditions like chronic fatigue syndrome. Researchers found that certain infections (like Lyme disease and hepatitis C) have been linked to fibromyalgia, and some people report symptoms starting after vaccinations, but antibiotics and antivirals don't appear to help treat fibromyalgia effectively. The authors suggest that vaccinations might act as one trigger among several factors that together cause these conditions.

Clinical activity of folinic acid in patients with chronic fatigue syndrome.

Lundell, Kathleen, Qazi, Sanjive, Eddy, Linda et al.·Arzneimittel-Forschung·2006

This study looked at 58 ME/CFS patients and found that most had weakened immune systems with low levels of a type of immune cell called B-lymphocytes, and most also had reactivated Epstein-Barr virus (EBV) infection. When researchers gave patients folinic acid (a form of vitamin B), about 81% reported feeling better. The findings suggest that folinic acid might help some ME/CFS patients and that immune problems may play a role in the illness.

Exploration of statistical dependence between illness parameters using the entropy correlation coefficient.

Craddock, R Cameron, Taylor, Renee, Broderick, Gordon et al.·Pharmacogenomics·2006

Researchers tested a new statistical method called the entropy correlation coefficient to identify which ME/CFS symptoms and test results are related to each other. They studied 130 women and found that fatigue-related measures were strongly connected to each other, as were general quality-of-life measures and depression scores. Importantly, they discovered some relationships between cognitive test results and ME/CFS that hadn't been found with traditional statistical methods.

[Possible mechanisms of chronic fatigue syndrome in multiple sclerosis].

Kasatkin, D S, Spirin, N N·Zhurnal nevrologii i psikhiatrii imeni S.S. Korsakova·2006

This review describes how fatigue in multiple sclerosis (MS) can happen in different ways: tiredness even at rest, exhaustion during activity, and fatigue linked to MS flare-ups. The authors explain that fatigue likely involves both brain-based and body-based mechanisms, and often occurs alongside depression and sleep problems, suggesting these conditions may share common biological causes related to brain chemicals like serotonin.

Efficacy of neurotropin in chronic fatigue syndrome: a case report.

Toda, Katsuhiro, Kimura, Hiroaki·Hiroshima journal of medical sciences·2006

This case report describes one 28-year-old man with ME/CFS who was treated with a medication called Neurotropin (four tablets daily). His fatigue and widespread pain began improving within a week, and his sleep, focus, and memory improved within two weeks. He stopped taking the medication after 11 weeks and remained symptom-free for at least 5 months afterward.

Identifying illness parameters in fatiguing syndromes using classical projection methods.

Broderick, Gordon, Craddock, R Cameron, Whistler, Toni et al.·Pharmacogenomics·2006

Researchers studied 111 women to find common patterns that distinguish ME/CFS patients from healthy controls by looking at both their symptoms and gene activity in blood cells. They used a statistical method to combine multiple pieces of information—like fatigue scores, quality of life measures, and which genes were active—rather than looking at single factors alone. The analysis identified key differences related to stress in cells, immune problems, and imbalanced minerals, particularly reflected in abnormal heart rate patterns during sleep.

Psychomotor speed: possibly a new marker for overtraining syndrome.

Nederhof, Esther, Lemmink, Koen A P M, Visscher, Chris et al.·Sports medicine (Auckland, N.Z.)·2006

This study proposes that measuring how quickly someone can respond to mental tasks (psychomotor speed) might help identify athletes who are overtraining before serious problems develop. The researchers noticed that overtraining syndrome shares some features with chronic fatigue syndrome and depression, both of which involve slowed mental processing, and suggest this slowness could be an early warning sign.

CFSUM1 and CFSUM2 in urine from patients with chronic fatigue syndrome are methodological artefacts.

Chalmers, Ronald A, Jones, Mark G, Goodwin, C Stewart et al.·Clinica chimica acta; international journal of clinical chemistry·2006

An earlier study claimed to find two special markers in the urine of ME/CFS patients that could help diagnose the condition. This study re-examined those findings and discovered that these supposed markers were actually just artifacts—unintended byproducts created by the way the urine samples were prepared in the lab, not real biological differences between patients and healthy people.

Explanatory and pragmatic perspectives regarding idiopathic physical symptoms and related syndromes.

Engel, Charles C·CNS spectrums·2006

This paper discusses two different ways to approach studying and treating illnesses like ME/CFS that don't have a clear, well-understood cause. One approach focuses on finding the root cause in controlled settings; the other focuses on whether treatments actually work in real-world patient care. The authors argue that for conditions like ME/CFS, the practical approach—focusing on what helps patients in everyday life—may be more useful than searching for a single underlying cause.

Toward a trajectory of identity reconstruction in chronic fatigue syndrome/myalgic encephalomyelitis: a longitudinal qualitative study.

Whitehead, Lisa·International journal of nursing studies·2006

This study followed 17 people with ME/CFS over time to understand how the illness changed how they saw themselves. The researchers found that people's sense of identity shifted depending on how sick they were and how others treated them. Over the long term, most people developed ways to cope that helped them build a more stable sense of who they were, even while managing their illness.

Quest, chaos and restitution: living with chronic fatigue syndrome/myalgic encephalomyelitis.

Whitehead, Lisa Claire·Social science & medicine (1982)·2006

This study looked at how 17 people with ME/CFS describe their illness and make sense of it. Researchers found that people often go through different ways of telling their story: first trying to get back to normal (restitution), then feeling overwhelmed by chaos, and eventually finding new meaning in their lives (quest narrative). Understanding these patterns helps explain how people cope with a long-term illness that's hard to diagnose and often misunderstood.
