Objective sleep measures in chronic fatigue syndrome patients: A systematic review and meta-analysis.

Mohamed, Abdalla Z, Andersen, Thu, Radovic, Sanja et al.·Sleep medicine reviews·2023

This study looked at 24 research papers that measured sleep objectively (using devices and tests, not just patient reports) in people with ME/CFS. The researchers found that ME/CFS patients do indeed have real, measurable sleep problems—they take longer to fall asleep, wake up more during the night, and don't get good-quality sleep. Interestingly, these sleep problems looked slightly different in teenagers compared to adults with ME/CFS.

Effectiveness of Pain Neuroscience Education in Patients with Chronic Musculoskeletal Pain and Central Sensitization: A Systematic Review.

Lepri, Beatrice, Romani, Daniele, Storari, Lorenzo et al.·International journal of environmental research and public health·2023

This review looked at 15 studies testing whether pain neuroscience education—teaching patients how pain works in the nervous system—helps people with chronic muscle and joint pain, including those with conditions like fibromyalgia and chronic fatigue syndrome. The research found that this type of education does appear to reduce pain and improve disability and mood, especially when delivered one-on-one and combined with other treatments like physical therapy.

Female reproductive health impacts of Long COVID and associated illnesses including ME/CFS, POTS, and connective tissue disorders: a literature review.

Pollack, Beth, von Saltza, Emelia, McCorkell, Lisa et al.·Frontiers in rehabilitation sciences·2023

This review examined how Long COVID and related illnesses like ME/CFS affect women's reproductive health, including menstrual cycles, fertility, and pregnancy. The researchers found that women with these conditions experience more problems with their periods, difficulty getting pregnant, and symptom flare-ups around their menstrual cycle. The study highlights that we need much more research to understand these reproductive health issues and to help doctors better support women with these conditions.

Surveying the Metabolic and Dysfunctional Profiles of T Cells and NK Cells in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome.

Maya, Jessica·International journal of molecular sciences·2023

This review examined research on how immune cells (T cells and NK cells) work differently in ME/CFS patients compared to healthy people. The authors found evidence that these immune cells may be exhausted or damaged, similar to what happens in chronic viral infections. Understanding why these immune cells aren't functioning properly could help explain ME/CFS symptoms and guide development of better treatments.

The relation between cognitive-behavioural responses to symptoms in patients with long term medical conditions and the outcome of cognitive behavioural therapy for fatigue - A secondary analysis of four RCTs.

de Gier, M, Picariello, F, Slot, M et al.·Behaviour research and therapy·2023

This study looked at how people with different long-term illnesses—including ME/CFS—think and behave in response to fatigue, and whether these patterns affect how well cognitive behavioural therapy (CBT) works. Researchers found that certain thought patterns and behaviours, like avoiding activity or believing that fatigue causes damage, were linked to less improvement with CBT. The good news is that when CBT helped patients change these patterns—by reducing fear, worry, and excessive rest—their fatigue improved significantly.

DNA Methylation Signatures of Functional Somatic Syndromes: Systematic Review.

Fischer, Susanne, Kleinstäuber, Maria, Fiori, Laura M et al.·Psychosomatic medicine·2023

This review looked at research on DNA changes in people with ME/CFS, fibromyalgia, and irritable bowel syndrome. Scientists found that people with these conditions have different patterns of chemical switches on their genes compared to healthy people, particularly in genes that control immune function and stress response. These differences may help explain why people with ME/CFS experience fatigue, pain, and other symptoms.

Animal Models for Neuroinflammation and Potential Treatment Methods.

Tamura, Yasuhisa, Yamato, Masanori, Kataoka, Yosky·Frontiers in neurology·2022

This review looked at how ME/CFS may be caused by inflammation in the brain and examined animal studies testing anti-inflammatory treatments. Researchers found that brain inflammation is connected to how severe ME/CFS symptoms are, and that certain compounds with anti-inflammatory properties showed promise in reducing these inflammatory responses in animal models. This suggests that anti-inflammatory medicines might help improve symptoms in ME/CFS patients.

Fatigue in ANCA-associated vasculitis (AAV) and systemic sclerosis (SSc): similarities with Myalgic encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). A critical review of the literature.

van Eeden, Charmaine, Osman, Mohammed S, Cohen Tervaert, Jan Willem·Expert review of clinical immunology·2022

This review examined severe, long-lasting fatigue in patients with certain autoimmune diseases and compared it to ME/CFS. The researchers found that fatigue in these autoimmune diseases shares similarities with ME/CFS, including common immune and metabolic problems. Importantly, this fatigue often persists even after the main disease is brought under control, suggesting it may need different treatment approaches than the underlying condition.

Could the kynurenine pathway be the key missing piece of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) complex puzzle?

Kavyani, Bahar, Lidbury, Brett A, Schloeffel, Richard et al.·Cellular and molecular life sciences : CMLS·2022

This review explores whether problems with how your body processes an amino acid called tryptophan might explain ME/CFS symptoms. The kynurenine pathway is a biochemical process that helps your cells make energy and affects immune function and brain inflammation. The authors suggest that abnormalities in this pathway could be a missing piece in understanding why ME/CFS develops.

Acupuncture and moxibustion for chronic fatigue syndrome: A systematic review and network meta-analysis.

Fang, Yang, Yue, Bo-Wen, Ma, Han-Bo et al.·Medicine·2022

This review looked at 51 studies testing whether acupuncture and moxibustion (traditional Chinese medicine treatments) help people with chronic fatigue syndrome. The researchers combined results from these studies and found that traditional Chinese medicine treatments, especially moxibustion alone or combined with acupuncture, showed better improvements in fatigue symptoms compared to other treatments like standard Western medicines.

Systemic conditions associated with increased risk to develop oral squamous cell carcinoma: Systematic review and meta-analysis.

Dos Santos, Erison Santana, Pérez-de-Oliveira, Maria Eduarda, Normando, Ana Gabriela Costa et al.·Head & neck·2022

This review looked at whether people with certain long-term health conditions—including chronic fatigue syndrome (ME/CFS)—are at higher risk for developing oral squamous cell carcinoma (a type of mouth cancer). Researchers analyzed data from over 1 million patients worldwide and found that people with ME/CFS, along with several rare genetic conditions and those who had bone marrow transplants, do have an increased risk. The study suggests doctors should pay special attention to mouth health in patients with these conditions.

Genetics of COVID-19 and myalgic encephalomyelitis/chronic fatigue syndrome: a systematic review.

Tziastoudi, Maria, Cholevas, Christos, Stefanidis, Ioannis et al.·Annals of clinical and translational neurology·2022

This study looked at genetic research on both COVID-19 and ME/CFS to see if they share common genetic factors that might explain why both conditions cause extreme fatigue. Researchers reviewed 71 studies on COVID-19 genetics and 26 studies on ME/CFS genetics, then identified six genes that appear in both conditions. The findings suggest that immune system dysfunction—specifically problems with inflammation and how immune cells communicate—may play a role in both illnesses.

Breast Implant-Associated Immunological Disorders.

Suh, Lily J, Khan, Imran, Kelley-Patteson, Christine et al.·Journal of immunology research·2022

This review examined reports of illness associated with breast implants, which can cause fatigue, joint pain, difficulty concentrating, and other symptoms similar to those in ME/CFS. Researchers found evidence that breast implants may trigger autoimmune problems in some people, and that removing implants improved symptoms in over half of patients studied. The review suggests that bacterial infections around implants, rather than the implant material itself, might be responsible for these problems.

Ginseng for the Treatment of Chronic Fatigue Syndrome: A Systematic Review of Clinical Studies.

Yang, Juan, Shin, Kyung-Min, Abu Dabrh, Abd Moain et al.·Global advances in health and medicine·2022

Researchers looked at whether ginseng, a plant supplement used for fatigue in other conditions, might help people with ME/CFS. They found only 2 small studies with a total of 68 patients. While the results suggest ginseng might be helpful, there isn't enough evidence yet to say for certain whether it works or is safe for ME/CFS patients.

Long-Term COVID 19 Sequelae in Adolescents: the Overlap with Orthostatic Intolerance and ME/CFS.

Morrow, Amanda K, Malone, Laura A, Kokorelis, Christina et al.·Current pediatrics reports·2022

Some teenagers who had COVID-19 develop long-lasting symptoms months after their initial infection, even if they weren't severely ill at first. These long COVID symptoms—like extreme fatigue, brain fog, and difficulty standing—look very similar to ME/CFS. This review examines how common long COVID is in teens and explains why current treatments don't work well for everyone because long COVID may actually be several different conditions.

Analysis of post COVID-19 condition and its overlap with myalgic encephalomyelitis/chronic fatigue syndrome.

Sukocheva, Olga A, Maksoud, Rebekah, Beeraka, Narasimha M et al.·Journal of advanced research·2022

This study compared long-term effects of COVID-19 infection (long-COVID) with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) to see how similar they are. Researchers found that many people who develop long-COVID experience the same symptoms as ME/CFS patients, including severe fatigue, brain fog, headaches, and worsening of symptoms after physical activity. The study suggests that COVID-19 may trigger a ME/CFS-like condition in some people through inflammatory processes in the body.

Fatigue, post-exertional malaise and orthostatic intolerance: a map of Cochrane evidence relevant to rehabilitation for people with post COVID-19 condition.

Arienti, Chiara, Cordani, Claudio, Lazzarini, Stefano G et al.·European journal of physical and rehabilitation medicine·2022

This study looked at what treatments have helped people with fatigue and exercise problems in other conditions to understand what might help people with long COVID. Researchers found that exercise programs, telehealth rehabilitation, and educational interventions showed promise for fatigue, while combined aerobic and anaerobic training helped with exercise intolerance. However, they found very little research specifically on post-exertional malaise (feeling much worse after activity) or orthostatic intolerance (dizziness when standing), which are key symptoms in post-COVID and ME/CFS.

Stabilometric Biofeedback Training in Cognitive and Affective Function Improvement. Contribution of the Russian Scientific School. Part II.

Bazanova, O M, Kovaleva, A V·Human physiology·2022

This review examines how balance training using computer feedback can help improve thinking, mood, and symptom management in people with chronic fatigue syndrome and other neurological conditions. The researchers looked at studies from Russia and other countries that used a technique called stabilometric biofeedback, which shows patients real-time information about their body's balance and posture to help them improve control and function.

The Updated NICE Guidance Exposed the Serious Flaws in CBT and Graded Exercise Therapy Trials for ME/CFS.

Vink, Mark, Vink-Niese, Alexandra·Healthcare (Basel, Switzerland)·2022

This study reviewed the evidence that was used to support two common ME/CFS treatments: cognitive behavioural therapy (CBT) and graded exercise therapy (GET). The authors found that the studies supporting these treatments had serious design problems—such as unclear definitions of recovery, not properly measuring actual improvements, and not publishing results that didn't support the treatments. The authors conclude that these flawed studies don't actually prove CBT and GET work, which aligns with the new British health guidelines recommending against these treatments.

Human Herpesvirus 6 Infection and Risk of Chronic Fatigue Syndrome: A Systematic Review and Meta-Analysis.

Mozhgani, Sayed-Hamidreza, Rajabi, Farid, Qurbani, Mohsen et al.·Intervirology·2022

This study reviewed and combined the results of 17 different research studies to see if there's a connection between a common virus called HHV-6 and ME/CFS. The researchers found evidence suggesting that HHV-6 infection may be associated with developing ME/CFS, but they emphasize that more research is needed to fully understand this relationship.
