Post-bacterial infection chronic fatigue syndrome is not a latent infection.

Melenotte, Cléa, Drancourt, Michel, Gorvel, Jean Pierre et al.·Medecine et maladies infectieuses·2019

This review examined whether bacteria that stay dormant (inactive) in the body after an infection could cause chronic fatigue syndrome symptoms. The researchers looked at scientific evidence and found no proof that dormant bacteria cause the ongoing fatigue and other symptoms people experience after bacterial infections. The study suggests that psychological trauma and unknown causes may play a role in post-infection fatigue, rather than persistent bacterial infection.

Myalgic encephalomyelitis/chronic fatigue syndrome: From pathophysiological insights to novel therapeutic opportunities.

Morris, Gerwyn, Puri, Basant K, Walker, Adam J et al.·Pharmacological research·2019

This review examines what goes wrong in the bodies of ME/CFS patients and looks at treatments that might help. Researchers found that ME/CFS involves several biological problems, including inflammation, increased cellular stress, gut problems, and energy production issues. The review highlights five promising supplements—coenzyme Q10, melatonin, curcumin, molecular hydrogen, and N-acetylcysteine—that target these problems, though much more testing is needed.

Methodological Strategies for Ecological Momentary Assessment to Evaluate Mood and Stress in Adult Patients Using Mobile Phones: Systematic Review.

Yang, Yong Sook, Ryu, Gi Wook, Choi, Mona·JMIR mHealth and uHealth·2019

This review looked at research studies that used smartphones to track mood and stress in patients with various chronic illnesses, including ME/CFS. Researchers used apps or text-based systems to send prompts at random times throughout the day, asking patients to report how they were feeling in that moment. The review found that this method is practical and feasible for understanding how symptoms and emotions change during daily life.

A systematic review of enteric dysbiosis in chronic fatigue syndrome/myalgic encephalomyelitis.

Du Preez, S, Corbitt, M, Cabanas, H et al.·Systematic reviews·2018

Researchers reviewed seven studies looking at whether gut bacteria differences might cause ME/CFS symptoms. While all studies found some differences in gut bacteria between ME/CFS patients and healthy people, the findings were inconsistent and often not statistically significant. Currently, there isn't enough reliable evidence to say that abnormal gut bacteria are a major cause of ME/CFS.

The "Biology-First" Hypothesis: Functional disorders may begin and end with biology-A scoping review.

Enck, P, Mazurak, N·Neurogastroenterology and motility·2018

This study reviewed research showing that infections can trigger long-lasting functional disorders—conditions where the body doesn't work properly but standard tests appear normal. The authors propose that these disorders start from biological changes (like immune dysfunction or altered gut bacteria) caused by the infection, and that psychological factors develop as a result rather than being the root cause. This challenges the common belief that such conditions are mainly psychological or social in nature.

Multidisciplinary rehabilitation treatment is not effective for myalgic encephalomyelitis/chronic fatigue syndrome: A review of the FatiGo trial.

Vink, Mark, Vink-Niese, Alexandra·Health psychology open·2018

This analysis reviewed a major trial called FatiGo that compared two treatment approaches for ME/CFS: multidisciplinary rehabilitation (combining physical therapy, psychology, and other treatments) and cognitive behavioral therapy (CBT). While the original FatiGo trial claimed both treatments were effective, this review found serious problems with how the study was conducted and concluded that the evidence does not actually support these claims.

Graded exercise therapy for myalgic encephalomyelitis/chronic fatigue syndrome is not effective and unsafe. Re-analysis of a Cochrane review.

Vink, Mark, Vink-Niese, Alexandra·Health psychology open·2018

This study re-examined a major 2017 review that had concluded graded exercise therapy (GET) was helpful for ME/CFS. The researchers found serious problems with that review's methods and conclusions. They concluded there is no reliable evidence that GET works for ME/CFS, and safety concerns were not properly reported in the original trials.

Post-Exertional Malaise

[Neurologic Abnormalities in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: A Review].

Komaroff, Anthony L, Takahashi, Ryosuke, Yamamura, Takashi et al.·Brain and nerve = Shinkei kenkyu no shinpo·2018

This review examines objective, measurable evidence that ME/CFS is a real physical illness, not just a psychological condition. Researchers looked at studies showing that ME/CFS involves problems with the brain, immune system, and how the body uses energy. They found that immune activation—where the body's defense system becomes overactive—may be a key driver of ME/CFS symptoms.

The effect of physiotherapy on fatigue and physical functioning in chronic fatigue syndrome patients: A systematic review.

Galeoto, G, Sansoni, J, Valenti, D et al.·La Clinica terapeutica·2018

This review looked at four high-quality studies to understand how physical therapy might help people with ME/CFS feel less tired and function better. The researchers found that programs combining exercise, stretching, and body awareness techniques showed the most promise for reducing fatigue over medium and long-term periods. However, because there were very few studies to examine, the authors couldn't definitively say which treatment works best for everyone.

A Systematic Review of Probiotic Interventions for Gastrointestinal Symptoms and Irritable Bowel Syndrome in Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME).

Corbitt, Matthew, Campagnolo, N, Staines, D et al.·Probiotics and antimicrobial proteins·2018

This review looked at whether probiotics (beneficial bacteria) might help with stomach and bowel problems that many people with ME/CFS experience. Researchers searched medical databases and found 25 studies on this topic. While probiotics showed promise for irritable bowel syndrome in the general population, there wasn't enough good-quality research to say whether they actually help people with ME/CFS.

Chronic viral infections in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).

Rasa, Santa, Nora-Krukle, Zaiga, Henning, Nina et al.·Journal of translational medicine·2018

This review examined all existing research on whether viruses might cause ME/CFS. Scientists found that while many studies have looked at different viruses, the research has been poorly designed and inconsistent, making it hard to draw firm conclusions. The authors suggest that future studies need better planning and more rigorous methods to properly answer whether viruses play a role in ME/CFS.

Are probiotic treatments useful on fibromyalgia syndrome or chronic fatigue syndrome patients? A systematic review.

Roman, P, Carrillo-Trabalón, F, Sánchez-Labraca, N et al.·Beneficial microbes·2018

This review looked at whether probiotic supplements (live beneficial bacteria) might help people with ME/CFS or fibromyalgia. Researchers searched for high-quality studies and found only two small studies in ME/CFS patients. These studies showed that specific probiotic strains reduced anxiety and markers of inflammation, but there isn't enough evidence yet to say probiotics are a proven treatment.

Metabolic abnormalities in chronic fatigue syndrome/myalgic encephalomyelitis: a mini-review.

Tomas, Cara, Newton, Julia·Biochemical Society transactions·2018

This review examines research showing that people with ME/CFS have problems with how their bodies use energy at a cellular level. Scientists have found several different metabolic abnormalities—issues with immune function, mitochondria (the cell's power plants), muscle acid buildup, and other energy-related problems—that could potentially be used as biomarkers (measurable signs) to diagnose the disease. However, no single test can yet reliably identify ME/CFS.

A unifying theory for cognitive abnormalities in functional neurological disorders, fibromyalgia and chronic fatigue syndrome: systematic review.

Teodoro, Tiago, Edwards, Mark J, Isaacs, Jeremy D·Journal of neurology, neurosurgery, and psychiatry·2018

Many people with ME/CFS report cognitive problems like brain fog, forgetfulness, and difficulty concentrating. This review of 95 studies found that while patients consistently describe these symptoms, standard memory and thinking tests often show normal or only mild problems. The authors suggest that pain, fatigue, and the body's excessive self-monitoring may force the brain to work harder on everyday tasks, making thinking feel more exhausting even when test results look relatively normal.

Cognitive Impairment

A Review Study on the Beneficial Effects of Baduanjin.

Zou, Liye, Pan, Zhujun, Yeung, Albert et al.·Journal of alternative and complementary medicine (New York, N.Y.)·2018

This review looked at 22 studies about Baduanjin, a gentle Chinese exercise that combines movement with mental focus. The studies suggest that Baduanjin may help improve thinking abilities, mood, sleep, and physical symptoms in people with various conditions, including those with chronic fatigue-like illness. However, the authors note that better-quality, longer-lasting studies are needed before we can be confident about these benefits.

Exercise therapy is a beneficial intervention for chronic fatigue syndrome (PEDro synthesis).

Dannaway, Jasan, New, Cameron C, New, Charles H et al.·British journal of sports medicine·2018

This review examined multiple studies to determine whether exercise therapy helps people with ME/CFS. The researchers looked at existing evidence to see if physical activity programs could improve fatigue and other symptoms. However, it's important to note that findings on exercise for ME/CFS are complex and sometimes controversial in the patient community.

Does the microbiome and virome contribute to myalgic encephalomyelitis/chronic fatigue syndrome?

Newberry, Fiona, Hsieh, Shen-Yuan, Wileman, Tom et al.·Clinical science (London, England : 1979)·2018

This review examines whether changes in the bacteria living in our gut and the viruses that affect those bacteria might contribute to ME/CFS. While previous studies have focused mainly on bacterial changes, this paper points out that viruses—especially those that attack bacteria—are equally important to understand. The authors explain that inconsistencies between different microbiome studies make it hard to draw clear conclusions, and call for more standardized research methods.

A systematic review of outcome measures utilised to assess self-management in clinical trials in patients with chronic pain.

Banerjee, Anirban, Hendrick, Paul, Bhattacharjee, Purba et al.·Patient education and counseling·2018

This review looked at 25 studies to find out which questionnaires and tests best measure how well people manage their chronic pain on their own. Researchers found 14 different measurement tools that assess things like pain coping skills, confidence, and self-care. The review suggests that tools measuring multiple aspects of self-management—like the Chronic Pain Coping Inventory and Health Education Impact Questionnaire—work best for tracking how people manage their conditions.

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome - Evidence for an autoimmune disease.

Sotzny, Franziska, Blanco, Julià, Capelli, Enrica et al.·Autoimmunity reviews·2018

This review examines evidence that ME/CFS may be caused by the immune system attacking the body (autoimmune disease). Researchers found that people with ME/CFS have unusual immune patterns, including abnormal antibodies and changes in immune cells. Importantly, a treatment that removes certain immune cells (rituximab) helped about half of ME/CFS patients in clinical trials, suggesting an autoimmune mechanism in at least some people.

WITHDRAWN: Traditional Chinese medicinal herbs for the treatment of idiopathic chronic fatigue and chronic fatigue syndrome.

Adams, Denise, Wu, Taixiang, Yang, Xunzhe et al.·The Cochrane database of systematic reviews·2018

Researchers searched for studies testing whether traditional Chinese herbal medicines could help treat ME/CFS and chronic fatigue. After reviewing over 2,400 studies across 13 databases, they found that while many studies existed, none met the strict standards needed to prove whether these herbs actually work. The main problem was that most studies, especially those from China, did not use proper scientific methods to fairly test the treatments.
