Ginseng as a treatment for fatigue

Review abstract:

Ginseng as a Treatment for Fatigue: A Systematic Review by Noel Arring, Denise Millstine, Lisa A Marks, Lillian M Nail in J Altern Complement Med. 2018 Apr 6.  [Epub ahead of print]

BACKGROUND:
Millions of people with chronic illness suffer from fatigue. Fatigue is a complex, multidimensional symptom with poorly understood causes, wide variations in severity among individuals, and negative effects on multiple domains of daily life. Many patients with fatigue report the use of herbal remedies. Ginseng is one of the most widely used because it is believed to improve energy, physical and emotional health, and well-being.

OBJECTIVE:
To systematically review the published evidence to evaluate the safety and effectiveness of the two types of Panax ginseng (Asian [Panax ginseng] and American [Panax quinquefolius]) as treatments for fatigue.

DESIGN:
PubMed, CINAHL (Cumulative Index to Nursing and Allied Health), Ovid MEDLINE, and EMBASE databases were searched using Medical Subject Heading and keyword terms, including ginseng, Panax, ginsenosides, ginsenoside* (wild card), fatigue, fatigue syndrome, cancer-related fatigue, and chronic fatigue. Studies were included if participants had fatigue, had used one of the two Panax ginsengs as an intervention, and had scores from a self-report fatigue measure. Two reviewers independently assessed each article at each review phase and met to develop consensus on included studies. Risk of bias was assessed using version 5.3 of the Cochrane Collaboration Review Manager (RevMan), and results were synthesized in a narrative summary.

RESULTS:
The search strategy resulted in 149 articles, with 1 additional article located through review of references. After titles, abstracts, and full text were reviewed, 139 articles did not meet inclusion criteria. For the 10 studies reviewed, there was a low risk of adverse events associated with the use of ginseng and modest evidence for its efficacy.

CONCLUSIONS:
Ginseng is a promising treatment for fatigue. Both American and Asian ginseng may be viable treatments for fatigue in people with chronic illness. Because of ginseng’s widespread use, a critical need exists for continued research that is methodologically stronger and that includes more diverse samples before ginseng is adopted as a standard treatment option for fatigue.

Reduction of glucocorticoid receptor function in CFS – no causal link to childhood trauma

Research abstract:

Reduction of glucocorticoid receptor function in CFS, by Megan Lynn, Laura Maclachlan, Andreas Finkelmeyer, James Clark, James Locke, Stephen Todryk, Wan-Fai Ng, Julia L Newton, Stuart Watson in Mediators of Inflammation [Preprint April 20, 2018]

Glucocorticoid receptor (GR) function may have aetiopathogenic significance in chronic fatigue syndrome (CFS), via its essential role in mediating inflammatory responses as well as in hypothalamic-pituitary-adrenal axis regulation. GR function can be estimated ex-vivo by measuring dexamethasone (dex) modulation of cytokine response to lipopolysaccharide (LPS), and in-vivo using the impact of dex on cortisol levels.

This study aimed to compare GR function between CFS (n=48), Primary Sjogren’s Syndrome (a disease group control) (n=27), and sedentary healthy controls (HCs) (n=20) and to investigate its relationship with clinical measures.

In the GR ex-vivo response assay whole blood was diluted and incubated with LPS (to stimulate cytokine production), with or without 10 or 100 nanomolar concentrations of dex. Cytometric bead array (CBA) and flow cytometry enabled quantification of cytokine levels (TNF-alpha interleukin (IL)- 6 and IL-10) in the supernatants.

In the in-vivo response assay, five plasma samples were taken for determination of total cortisol concentration using ELISA at half hourly intervals on two consecutive mornings separated by ingestion of 0.5mg of dex at 11pm. The association of the data from the in-vivo and ex-vivo analyses with reported childhood adversity were also examined.

CFS patients had reduced LPS-induced IL-6 and TNF-alpha production compared to both control groups and reduced suppression of TNF-alpha by the higher dose of dex compared to HCs. Cortisol levels, before or after dex did not differ between CFS and HCs.

Cortisol levels were more variable in CFS than HCs. In the combined group (CFS plus HC) cortisol concentrations positively, and ex-vivo GR function (determined by dex mediated suppression of Il-10) negatively, correlated with childhood adversity score.

The results do not support the hypothesis that GR dysregulation is aetiopathogenic in CFS and suggest that current and future endocrine cross sectional studies in CFS may be vulnerable to the confounding influence of childhood trauma which is likely increased by
co-morbid depression.

NB [Basically, the endocrine abnormalities (cortisol mainly, but others too), and presumably the so-called link to stress as a cause, are overstated. They’re probably not causative.]

The putative role of oxidative & inflammation in the pathophysiology of sleep dysfunction across neuropsychiatric disorders

Review summary:

The putative role of oxidative stress and inflammation in the pathophysiology of sleep dysfunction across neuropsychiatric disorders: Focus on chronic fatigue syndrome, bipolar disorder and multiple sclerosis, by Gerwyn Morris, Brendon Stubbs, Cristiano A Köhlerx, Ken Walder, Anastasiya Slyepchenko, Michael Berk, André F. Carvalho in Sleep Medicine Reviews [Published online: April 04, 2018]

Sleep and circadian abnormalities are prevalent and burdensome manifestations of diverse neuro-immune diseases, and may aggravate the course of several neuropsychiatric disorders. The underlying pathophysiology of sleep abnormalities across neuropsychiatric disorders remains unclear, and may involve the inter-play of several clinical variables and mechanistic pathways.

In this review, we propose a heuristic framework in which reciprocal interactions of immune, oxidative and nitrosative stress, and mitochondrial pathways may drive sleep abnormalities across potentially neuroprogressive disorders. Specifically, it is proposed that systemic inflammation may activate microglial cells and astrocytes in brain regions involved in sleep and circadian regulation.

Activated glial cells may secrete pro-inflammatory cytokines (for example, interleukin-1 beta and tumour necrosis factor alpha), nitric oxide and gliotransmitters, which may influence the expression of key circadian regulators (e.g., the Circadian Locomotor Output Cycles Kaput (CLOCK) gene). Furthermore, sleep disruption may further aggravate oxidative and nitrosative, peripheral immune activation, and (neuro) inflammation across these disorders in a vicious pathophysiological loop.

This review will focus on chronic fatigue syndrome, bipolar disorder, and multiple sclerosis as exemplars of neuro-immune disorders. We conclude that novel therapeutic targets exploring immune and oxidative & nitrosative pathways (p.e. melatonin and molecular hydrogen) hold promise in alleviating sleep and circadian dysfunction in these disorders.

Inquest Ruling: Young drama student Merryn Crofts killed by ME

ME Association blog post by John Siddle, 18 May 2018: Inquest Ruling: Young drama student Merryn Crofts killed by M.E. 

A devastating disease that some experts insist is all in the mind led to the death of a young drama student, a landmark inquest today ruled.

Merryn Crofts, 21, weighed less than six stone and had spent the last three years of her life totally bed-bound with severe ME – an incurable condition that affects 250,000 people in the UK.

The youngster was unable to take more than two teaspoons of food before suffering immense gut pain and vomiting, a coroner was told.

Merryn, from Rochdale, today became only the second person in the UK to have M.E. – myalgic encephalomyelitis – listed on a death certificate.

Despite being classed as a real neurological disease, many think the condition is not real – even within the medical profession.

Merryn’s mum, Clare Norton, sobbed as she told Rochdale Coroner’s Court how her “beautiful” and “energetic” daughter was left wheelchair-bound and reliant on tube feeding.

She said:  “As a child, she was a bundle of energy. She didn’t walk anywhere – she would hop, skip and jump.

“She was the kind of person that people gravitated towards. They wanted to be her friend.

“She was very social and loved drama. She was a total fashionista, a typical teenager. Her bedroom was a mess of clothes, hairspray and tan.

“But she was also stubborn, and I think that helped her cope with her illness in a lot of ways. She never gave up.”

In August 2011, Merryn, then 15, was diagnosed with hives and swelling shortly after coming back from a family holiday in Mallorca.

Tests in early 2012 revealed that at some point she had contracted glandular fever – a virus which can trigger M.E.

Despite dozens of medical appointments – including mental health checks for panic attacks – Merryn’s condition deteriorated as she suffered breathing problems, exhaustion and excruciating hypersensitivity to touch, light and sound.

She was eventually diagnosed with M.E. in the summer of 2012.

The would-be theatre star, who was forced to wear an eye mask, also suffered from severe migraines, brain fog, slurred speech and persistent infections.

Stomach problems, and problems swallowing, meant that her weight plummeted to just five-and-a-half stone.Coroner Katherine McKenna was told that Merryn could take on just 100 calories a day because her gut was in so much pain, and that, by 2015, even two teaspoons of nutrients were intolerable.

Merryn was eventually fitted with an intravenous nutrition line but suffered intestinal failure and was given a terminal diagnosis in 2016.

She died on May 23, 2017, just days after her 21st birthday.

Mrs McKenna today concluded her cause of death as starvation caused by a withdrawal of supportive nutrition, caused by M.E. She described Merryn as someone who “bore her suffering with dignity and good grace”.

She said: “Merryn had suffered with M.E. since 2012 which caused severe fatigue, gastrointestinal failure, chronic pain, global hypersensitivity, loss of mobility and function.

“Despite extensive investigations no reason for her gastrointestinal failure which led to her reliance on supportive nutrition was found and it most likely it was caused by her M.E.”

Mum Clare, who attended the inquest with daughter Amy Williams and Merryn’s stepdad Dave Norton, told of her long-standing belief that M.E. contributed to her death.

She said: “With M.E. the key symptom is post-exertional malaise. That means if someone’s energy is pushed beyond what they can tolerate, it will trigger all their symptoms.

“The best advice we were given was for Merryn to do just 50% of what she felt capable of.

“But Merryn didn’t even have 50% to give. She was always crashing, so everything that happened to her kept pushing her further behind.”

Pathologist Daniel DuPlessis said that a post-mortem showed low-grade inflammation of nerve roots. It was suggested that this inflammation could have made her bowel hypersensitive to processing nutrients.

Dr DuPlessis pointed out that Merryn had inflammation of the ganglia – gatekeepers to sensations in the brain. A post-mortem into the only other UK death attributed to ME, Sophia Mirza, 32, in 2006, also found ganglionitis.

M.E. expert at Salford Royal hospital, Dr Annice Mukherjee, said she was convinced that the illness was responsible for triggering Merryn’s intestinal failure.

NB  While it is possible that only 2 people have been recorded as dying of ME. Other people in the UK have had CFS listed as a cause of death on their death certificates, 1 known in Wales.

The high costs of low-grade inflammation

Review abstract:

The High Costs of Low-Grade Inflammation: Persistent Fatigue as a Consequence of Reduced Cellular-Energy Availability and Non-adaptive Energy Expenditure. by Tamara E. Lacourt, Elisabeth G. Vichaya, Gabriel S. Chiu, Robert Dantzer and Cobi J. Heijnen in Front Behav Neurosci. 2018 Apr 26;12:78.

Chronic or persistent fatigue is a common, debilitating symptom of several diseases. Persistent fatigue has been associated with low-grade inflammation in several models of fatigue, including cancer-related fatigue and chronic fatigue syndrome. However, it is unclear how low-grade inflammation leads to the experience of fatigue. We here propose a model of an imbalance in energy availability and energy expenditure as a consequence of low-grade inflammation.

In this narrative review, we discuss how chronic low-grade inflammation can lead to reduced cellular-energy availability. Low-grade inflammation induces a metabolic switch from energy-efficient oxidative phosphorylation to fast-acting, but less efficient, aerobic glycolytic energy production; increases reactive oxygen species; and reduces insulin sensitivity.  These effects result in reduced glucose availability and, thereby, reduced cellular energy. In addition, emerging evidence suggests that chronic low-grade inflammation is associated with increased willingness to exert effort under specific circumstances.

Circadian-rhythm changes and sleep disturbances might mediate the effects of inflammation on cellular-energy availability and non-adaptive energy expenditure.

In the second part of the review, we present evidence for these metabolic pathways in models of persistent fatigue, focusing on chronic fatigue syndrome and cancer-related fatigue. Most evidence for reduced cellular-energy availability in relation to fatigue comes from studies on chronic fatigue syndrome. While the mechanistic evidence from the cancer-related fatigue literature is still limited, the sparse results point to reduced cellular-energy availability as well.

There is also mounting evidence that behavioral-energy expenditure exceeds the reduced cellular-energy availability in patients with persistent fatigue. This suggests that an inability to adjust energy expenditure to available resources might be one mechanism underlying persistent fatigue.

Brain function characteristics of CFS

Research abstract:

Brain function characteristics of chronic fatigue syndrome: A task fMRI study, by
Zack Y Shan, Kevin Finegan, Sandeep Bhutab, Timothy Ireland, Donald R Staines, Sonya M.Marshall-Gradisnik, Leighton R.Barnden in NeuroImage: Clinical
Vol 19, 2018, Pages 279-286

Highlights

  • CFS patients recruit larger BOLD activation areas for the Stroop task.
  • BOLD signal complexities in CFS are lower in ten activated regions.
  • The BOLD signal complexity is correlated with the SF-36 health score across all subjects.
  • The BOLD signal complexity explains more than 40% of variance in the health score across all subjects.

Abstract

The mechanism underlying neurological dysfunction in chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) is yet to be established. This study investigated the temporal complexity of blood oxygenation level dependent (BOLD) changes in response to the Stroop task in CFS patients.

43 CFS patients (47.4 ± 11.8 yrs) and 26 normal controls (NCs, 43.4 ± 13.9 yrs) were included in this study. Their mental component summary (MCS) and physical component summary (PCS) from the 36-item Short Form Health Survey (SF-36) questionnaire were recorded. Their Stroop colour-word task performance was measured by accuracy and response time (RT). The BOLD changes associated with the Stroop task were evaluated using a 2-level general linear model approach. The temporal complexity of the BOLD responses, a measure of information capacity and thus adaptability to a challenging environment, in each activated region was measured by sample entropy (SampEn).

The CFS patients showed significantly longer RTs than the NCs (P < 0.05) but no significant difference in accuracy. One sample t-tests for the two groups (Family wise error adjusted PFWE < 0.05) showed more BOLD activation regions in the CFS, although a two sample group comparison did not show significant difference. BOLD SampEns in ten regions were significantly lower (FDR-q < 0.05) in CFS patients. BOLD SampEns in 15 regions were significantly associated with PCS (FDR-q < 0.05) and in 9 regions were associated with MCS (FDR-q < 0.05) across all subjects. SampEn of the BOLD signal in the medioventral occipital cortex could explain 40% and 31% of the variance in the SF-36 PCS and MCS scores, and those in the precentral gyrus could explain an additional 16% and 7% across all subjects.

This is the first study to investigate BOLD signal SampEn in response to tasks in CFS. The results suggest the brain responds differently to a cognitive challenge in patients with CFS, with recruitment of wider regions to compensate for lower information capacity.

Graphical abstract

The sample entropy (a measure of amount of information encoded in a temporal signal) of BOLD response to Stroop tasks in seven areas are significantly lower in patients with chronic fatigue syndrome (CFS) and significantly correlated health scores across all subjects, suggesting that the brain operates differently in CFS patients.

Association of T & NK cell phenotype with the diagnosis of ME/CFS

Research abstract:

Association of T and NK cell phenotype with the diagnosis of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), by Jose Luis Rivas, Teresa Palencia, Guerau Fernández, Milagros Garcia in Front. Immunol., 09 May 2018

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a pathological condition characterized by incapacitating fatigue and a combination of neurologic, immunologic, and endocrine symptoms.  At present its diagnosis is based exclusively on clinical criteria.

Several studies have described altered immunologic profiles; therefore, we proposed to further examine the more significant differences, particularly T and NK cell subpopulations that could be conditioned by viral infections, to discern their utility in improving the diagnosis and characterization of the patients.

The study included 76 patients that fulfilled the revised Canadian Consensus Criteria (CCC 2010) for ME/CFS and 73 healthy controls, matched for age and gender.

Immunophenotyping of different T cell and natural killer cell subpopulations in peripheral blood was determined by flow cytometry.

ME/CFS patients showed significantly lower values of T regulatory cells (CD4+CD25++(high)FOXP3+) and higher NKT-like cells (CD3+CD16+/−CD56+) than the healthy individuals. Regarding NK phenotypes, NKG2C was significantly lower and NKCD69 and NKCD56 bright were significantly higher in the patients group. A classification model was generated using the more relevant cell phenotype differences (NKG2C and T regulatory cells) that was able to classify the individuals as ME/CFS patients or healthy in a 70% of cases.

The observed differences in some of the subpopulations of T and NK cells between patients and healthy controls could define a distinct immunological profile that can help in the diagnostic process of ME/CFS patients, contribute to the recognition of the disease and to the search of more specific treatments. However, more studies are needed to corroborate these findings and to contribute to establish a consensus in diagnosis.
