Conditions that co-exist with long term CFS

Research abstract

Background: Epidemiologic data that inform our understanding of the type, frequency, and burden of co-morbidities with chronic fatigue syndrome is limited.

Purpose: To elucidate co-morbid and consequent conditions, using data from a clinical epidemiology study of long-term CFS patients.

Methods: Some 960 adults with CFS were identified at four sites specializing in the diagnosis and treatment of CFS. Patients reported their demographics, CFS course, other medical diagnoses, and current functioning.

We determined associations between: co-morbidities and a patient’s current health relative to their health when diagnosed with CFS; CFS symptom severity at onset and subsequent diagnosis with a co-morbid condition; and presence of a co-morbidity and functional ability. We also modeled the change in CFS symptom severity over time as it relates to the presence of a co-morbidity.

Results: Of the sample, 84% was diagnosed with one or more co-morbid conditions after CFS onset. Fibromyalgia, depression, anxiety, and hypothyroidism were the most common diagnoses. Nearly 60% of the sample reported a mental illness.

Conclusions: In general, co-morbid conditions reduced functional ability and were associated with the worsening of CFS symptoms over time. This study provides important new information on the prevalence of co-morbid conditions and their impact on the course of CFS.

Countess of Mar tells House of Lords that people with ME/CFS are treated “abominably” by caring professions

The Countess of Mar, (chair of the Forward ME Group) contributed to a short debate on NHS: Medical Competence and Skill in the House of Lords 7 January 2015.

My Lords, I, too, am grateful to the noble Lord, Lord Parekh, for introducing this Question for Short Debate this evening.

I encounter almost daily cases where people with ME/CFS and others with medically unexplained physical symptoms, known as MUPS, are treated abominably by members of supposedly caring professions.

For example—and it is by no means an isolated example—a young man of 17 had problems with tolerating foods since he was a small baby. Standard tests could provide no clear reason. By the time he was 16 he was diagnosed by consultant paediatricians at both St Thomas’ and Great Ormond Street hospitals as being extremely reactive to almost all foods and was restricted to a prescribed liquid diet, as none of the consultants had any other resolution. Eventually he was admitted to an environmental medicine polyclinic, where I am also treated, where he has been treated with low-dose immunotherapy and nutritional supplementation. Over a period of a few months, from being able to tolerate no foods he is now eating 33 different foods with few problems.

On his 17th birthday, he went out with some friends for a meal and during that night he developed very severe abdominal pain and, after his GP had refused to visit, his mother managed to get him to the polyclinic. There acute appendicitis was diagnosed and immediate admission to his local hospital in Oxford was recommended. The paediatric consultant’s first response was to ask, “What has the mother of this boy done now?”.

On arrival at the hospital the consultant informed the mother that he knew that nothing was wrong with the boy but he would keep him for observation. He scheduled a scan and then went home for the weekend. The boy was left screaming and in acute pain for a further 24 hours, without pain relief or other medication. By the time he was operated on, his appendix had perforated, making treatment much more complex than necessary.

To this day, despite all the evidence of the extremity of his reactions to foods and the failure of our two flagship hospitals to treat this young man’s condition, his Oxford consultant insists that there is nothing wrong with him, that he should stop the polyclinic treatment and that he should eat a normal diet, apparently because standard allergy tests do not provide confirmation. This results in great stress and distress to the boy and his mother.

In fact, substantive evidence in numerous publications proves that the safety and efficacy of immunological changes after treatment with oral immunotherapy for cow’s milk allergy, nut allergy, allergic rhinitis, wheat desensitisation and other specific foods and chemicals is well recognised. The treatments are validated and are neither experimental nor complementary medicine.

I have long wondered why there should be such particularly unreasonable treatment for people with MUPS and I have come to several conclusions. Medicine is supposed to be a very rewarding profession, whether the practitioner is a doctor, nurse or ancillary worker. The patient consults, the doctor diagnoses and prescribes and the patient gets better or at least no worse. On the occasions when the patient’s condition deteriorates and he or she dies, it is usually because the illness is well understood and this is part of a normal process. This is clearly not the case with MUPS. Modern doctors are highly reliant on technology. Test reports taken at face value can dominate the diagnostic process without taking into account factors such as clinical presentation and history and the possibility of false positive or negative results.

Additionally, medical practice has become a cost-benefit calculation, with treatments either enforced or rejected on this basis rather than on patient need. I have the distinct impression that, because some doctors and other medical practitioners fail to understand some disease processes, they grow impatient, even intolerant, when their patient fails to respond and then they blame the patient.

The skills that medical practitioners acquire during training are essential to good practice for the rest of their working lives. Unfortunately, the natural scientific curiosity of the profession seems to be stifled in the course of their training. There are still far too many medical professionals who hold that MUPS are “all in the mind” and that patients simply need to pull themselves together, perhaps with the help of a little cognitive behavioural therapy. Somehow, current research findings are not filtering down to doctors who deal with patients.

Are the time constraints on appointments and the dependence on technology reducing a doctor’s ability to listen and to communicate effectively? Is it because GPs and consultants work such long hours that they have neither the time nor the energy to do their own research on problems concerning chronically ill patients? Is it because complex investigations cost money and initial investigations come back as being within normal ranges that the current view is that further tests would not be cost effective? Or is it because doctors have become so demoralised that they can see no reason to go the extra mile on behalf of their patients?

The NHS is excellent for acute management of illness because clear guidelines are usually followed assiduously by all staff. Chronic complex conditions are problematic because clinicians seem to deal with only one symptom at a time. Specialisation means that patients with ME/CFS are rarely looked at holistically. I have heard of one doctor’s surgery with a notice on the door which reads, “One complaint at a time”. The trouble is that frequently it is the combination of symptoms which will point to a clear diagnosis.

I have confined my speech to one aspect of competence and skill, one which falls far short of the excellence that should be the norm. I am interested to hear how the Minister proposes to improve the position for some 250,000 patients with ME/CFS and the many more who have other medically unexplained symptoms.

The debate was answered by the Parliamentary Under Secretary of State for Health, Earl Howe.

In ME/CFS fear of exercise is a reasonable, knowledgeable, and learned response to a noxious stimulus

Prof Mark VanNess responds to the study published in the Lancet claiming that fear of exercise hinders recovery in CFS, in the Just ME blog:

I was saddened to see the press releases regarding the ME/CFS studies from Kings College London. It seems to me they’ve once again missed important nuances of the disease. Nearly all ME/CFS sufferers would either avoid or drop out of any experiment that employed exercise as a treatment because they know it exacerbates symptoms. The remaining subjects would either be very high functioning or consist of fatigued individuals that were incorrectly diagnosed as ME/CFS. Our studies clearly show that dynamic exercise like walking or jogging exacerbates symptoms associated with ME/CFS.

Fear and avoidance of what worsens symptoms is a natural defense mechanism against a harmful stimulus. In fact, many researchers here in the U.S. utilize graded aerobic exercise as a tool to worsen and amplify ME/CFS symptoms – not as a treatment meant to be beneficial. The therapeutic interventions we use are meant to improve quality of life for ME/CFS patients. These interventions focus primarily on strengthening muscles and improving range of motion; activities that get energy from normally functioning anaerobic metabolic mechanisms rather than impaired aerobic energy pathways. We even provide tools like heart rate monitors to help patients avoid significant aerobic exertion.

Fear of exercise is an understandable response in ME/CFS. For a patient with ME/CFS the fear of exercise is a reasonable, knowledgeable, and learned response to a noxious stimulus. If ME/CFS patients could exercise away their symptoms they most certainly would, regardless of the pain. But that is not the case. Our exercise physiologists carefully avoid aerobic exercise (which worsens the pathologies) and focus activity programs that utilize intact metabolic pathways with strength training and recumbent stretching (that help alleviate symptoms). These exercise recommendations are consistent with our understanding of ME/CFS pathology.

We would all hope that ME/CFS was viewed with attention given to immunological, metabolic, cardiovascular and neuroendocrinological dysfunction that has been demonstrated with previous research.

CFS prevalence and effect on job performance in nurses

Research abstract

Background and Objectives:

Chronic Fatigue Syndrome (CFS) is a severe, debilitating disorder.  Permanent chronic fatigue that affects the daily routine activities at least for six months and 4 of the 8 patients reported symptoms associated with this disorder (problems of memory / concentration, restless sleep, joint pain, swollen lymph nodes, muscle pain, headache, sore throat, weakness due to work) and the absence of any underlying disease is the another sign of this disorder.

One of the important things that is noticeable about the syndrome, is causing physical and mental disabilities in the person that will lead to approximately 50% reduction in his job performance.

Methods:

This study has been conducted through self-reported questionnaire and field and library studies. so the desired randomly set of 78 nurses have been selected to  answer the two demographic information and symptoms questionnaires CFS (DSQ. revised) which it’s reliability and validity has been verified. These questionnaires have been adjusted to the patient’s preliminary data record and their symptoms.

In the second stage, each individual job performance questionnaire was completed by department  head.

Results:

The information obtained from the chronic fatigue syndrome questionnaire shows 14.1% prevalence of CFS. In discussing the relationship between CFS and  indicators of job performance, it was cleared that people with the syndrome has lower job performance than those are healthy.

Conclusions:

In many similar studies, the effects of CFS on overall job performance in subjects were discussed and in most cases have been verified. The only differences are in subdivisions of job performance which are considered in this research

Conclusions from the full text:

Based on studies done so far, we can conclude that the  study of the effective factors (including CFS) on the nurses’ job performance and even other critical jobs is very necessary especially in those which job performance, how to interact with job, people involved, organizations and the community is very important.

Chronic fatigue syndrome has a considerable impact on job performance, to the extent that many studies has discerned that the loss rate in performance for affected people is 50 % compared to healthy people. This can be due to the factor which is the main reason for this disorder – chronic fatigue – that can effect on the performance indicators from the various aspects. For example, the intensity of the fatigue can affect their accuracy or ability to acquire new skills and training existing skills.

Sleep characteristics, exercise capacity and physical activity in CFS

Research abstract

Purpose:

Unrefreshing sleep and lowered physical activity are commonly observed in chronic fatigue syndrome (CFS) patients, but how they might influence each other remains unexplored. Therefore, this study simultaneously examined the exercise capacity, sleep characteristics and physical activity in CFS patients.

Methods:

Handgrip strength and cycle exercise capacity were assessed in 42 female CFS patients and 24 inactive control subjects. During four consecutive days and nights, energy expenditure, activity and sleep-wake pattern were objectively registered using a Sensewear Armband.

Results:

Exercise capacity was significantly lower in CFS patients. In both groups VO2peak correlated with the time subjects were physically active. In CFS patients only, VO2peak correlated negatively with sleeping during the day whilst physical activity level and energy expenditure correlated negatively with sleep latency and lying awake at night.

Conclusions:

In the present study, CFS patients with higher VO2peak tend to sleep less over day. Occupation in physical activities was negatively associated with sleep latency and lying awake at night. Increased physical activity potentially has beneficial effects on sleep quality in CFS. However, a close monitoring of the effects of increasing physical activity is essential to avoid negative effects on the health status of patients.

Implications for Rehabilitation

Female patients with chronic fatigue syndrome (CFS) have normal sleep latency and sleep efficiency, but sleep more and spent more time in bed as compared to healthy inactive women. Female CFS patients have lower exercise capacity, and a lower physical activity level as compared to healthy inactive women. CFS patients appear to be more sensitive for sleep quality (sleep latency and lying awake at night), which is associated with a low physical activity level.

A fatigue self-management approach could be cost effective

Research abstract

Background

Fatigue is a common yet difficult to treat condition in primary care. The objective of this study is to evaluate the cost-effectiveness of a brief cognitive behavioral therapy (CBT) based fatigue self-management (FSM) intervention as compared to usual care among patients with chronic fatigue in primary care.

Methods

An economic evaluation alongside of a parallel randomized controlled study design was used. Computer-generated variable-sized block randomization plan was used to assign patients into treatment groups and data collection staff were blinded to group assignments.

Patients aged between 18 and 65 years with at least six months of persistent fatigue and no medical or psychiatric exclusions were enrolled from a large primary care practice in Stony Brook, New York. The FSM group (n = 37) received two sessions of a nurse-delivered, fatigue self-management protocol and a self-help book and the usual care group (n = 36) received regular medical care.

The effectiveness measure was the Fatigue Severity Scale and the cost measure was total health care expenditures derived from monthly health services use diaries during follow-up. A societal perspective was adopted and bootstrapped incremental cost-effectiveness ratios (ICERs) and net monetary benefit (NMB) were calculated as measures of cost-effectiveness.

Results

The ICER for FSM was -$$2358, indicating that FSM dominates UC and it may generate societal cost savings as compared to usual care. Complete case analysis yielded smaller ICER (−$1199) with greater uncertainties. Net monetary benefit analysis showed that FSM has a probability of 0.833 (95% CI: 0.819, 0.847) to achieve positive NMB and the favorable results were not sensitive to assumptions about informal care or treatment costs.

Conclusion

This economic evaluation found initial evidence that a two-session brief CBT-based FSM may be cost-effective as compared to usual care over 12 months. The FSM intervention is potentially a promising intervention for chronic fatigue patients in primary care. Additional research is needed to examine the reproducibility and generalizability of these findings.

Isometric yoga improves pain and fatigue in CFS

Research abstract

Patients with chronic fatigue syndrome (CFS) often complain of persistent fatigue even after conventional therapies such as pharmacotherapy, cognitive behavioral therapy, or graded exercise therapy. The aim of this study was to investigate in a randomized, controlled trial the feasibility and efficacy of isometric yoga in patients with CFS who are resistant to conventional treatments.

Methods

This trial enrolled 30 patients with CFS who did not have satisfactory improvement after receiving conventional therapy for at least six months. They were randomly divided into two groups and were treated with either conventional pharmacotherapy (control group, n = 15) or conventional therapy together with isometric yoga practice that consisted of biweekly, 20-minute sessions with a yoga instructor and daily in-home sessions (yoga group, n = 15) for approximately two months.

The short-term effect of isometric yoga on fatigue was assessed by administration of the Profile of Mood Status (POMS) questionnaire immediately before and after the final 20-minute session with the instructor. The long-term effect of isometric yoga on fatigue was assessed by administration of the Chalder’s Fatigue Scale (FS) questionnaire to both groups before and after the intervention. Adverse events and changes in subjective symptoms were recorded for subjects in the yoga group.

Results

All subjects completed the intervention. The mean POMS fatigue score decreased significantly (from 21.9 ± 7.7 to 13.8 ± 6.7, P < 0.001) after a yoga session. The Chalder’s FS score decreased significantly (from 25.9 ± 6.1 to 19.2 ± 7.5, P = 0.002) in the yoga group, but not in the control group. In addition to the improvement of fatigue, two patients with CFS and fibromyalgia syndrome in the yoga group also reported pain relief.

Furthermore, many subjects reported that their bodies became warmer and lighter after practicing isometric yoga. Although there were no serious adverse events in the yoga group, two patients complained of tiredness and one of dizziness after the first yoga session with the instructor.

Conclusions

Isometric yoga as an add-on therapy is both feasible and successful at relieving the fatigue and pain of a subset of therapy-resistant patients with CFS.

Cytokine expression doesn’t reflect symptoms in adolsecent CFS

Highlights of Norwegian research

  • Chronic fatigue syndrome (CFS) might be related to altered cytokine expression.
  • A total of 120 adolescent CFS patients and 68 healthy controls were studied.
  • Individual cytokine levels where similar across the two groups.
  • Cytokine network parameters (ARACNE algorithm) were similar across the two groups.
  • In CFS patients, there were no associations between symptoms and network parameters.

Abstract

Chronic fatigue syndrome (CFS) is a prevalent and disabling condition among adolescents. The pathophysiology is poorly understood, but low-grade systemic inflammation has been suggested as an important component. This study compared circulating levels of individual cytokines and parameters of cytokine networks in a large set of adolescent CFS patients and healthy controls, and explored associations between cytokines and symptoms in the CFS group.

CFS patients (12–18 years old) were recruited nation-wide to a single referral center as part of the NorCAPITAL project (ClinicalTrials ID: NCT01040429). A broad case definition of CFS was applied, requiring three months of unexplained, disabling chronic/relapsing fatigue of new onset, whereas no accompanying symptoms were necessary. Thus, the case definition was broader than the Fukuda-criteria of CFS.

Healthy controls having comparable distribution of gender and age were recruited from local schools. Twenty-seven plasma cytokines, including interleukins, chemokines and growth factors were assayed using multiplex technology. The results were subjected to network analyses using the ARACNE algorithm. Symptoms were charted by a questionnaire, and patients were subgrouped according to the Fukuda-criteria.

A total of 120 CFS patients and 68 healthy controls were included. CFS patients had higher scores for fatigue (p < 0.001) and inflammatory symptoms (p < 0.001) than healthy controls. All cytokine levels and cytokine network parameters were similar, and none of the differences were statistically different across the two groups, also when adjusting for adherence to the Fukuda criteria of CFS. Within the CFS group, there were no associations between aggregate cytokine network parameters and symptom scores.

Adolescent CFS patients are burdened by symptoms that might suggest low-grade systemic inflammation, but plasma levels of individual cytokines as well as cytokine network measures were not different from healthy controls, and there were no associations between symptoms and cytokine expression in the CFS group. Low-grade systemic inflammation does not appear to be a central part of adolescent CFS pathophysiology.

Claims of ‘fear avoidance’ in ME are misleading

Following the publication of the latest PACE trail paper in the Lancet on 13th January,  there has been a flurry of media reports, many of which promote the findings as good news.

Other articles counter the claims saying:

  • people with ME are highly motivated to recover and be active
  • the paper ignores evidence of muscle, brain and immune system abnormalities in ME/CFS, which are more likely to cause the debilitating central (brain) and peripheral (muscle) fatigue
  • energy management programmes, not graded exercise, are more appropriate aids to recovery
  • CFS/ME is not one condition, but consists of subgroups, so patients need approaches that are tailored to the individual
  • the PACE trial produced evidence of only modest recovery
  • the PACE trial was accused of serious failings and inaccuracies in the way it conducted the trial, presented information and measured recovery
  • trial participants were told they would recover using CBT and GET so the study could have measured the placebo effect, not fear avoidance
  • contradicts earlier research by one of the researchers who found that CFS patients do not have an exercise phobia

WAMES joins other ME charities and organisations in rejecting the unscientific conclusions of the PACE trial and uncritical reporting of the study, and calls for research treatments that takes account of the research showing multi-system dysfunction.

ME Research UK writes: Fear avoidance of exercise?

The Lancet Psychiatry has just published the latest analysis based on data gathered during the MRC-funded PACE trial (2011). This is the sixth sub-analysis in the series – others have dealt with cost-effectiveness, pain, ‘recovery’, adverse effects and statistical methods – but it is the most difficult to understand, as it deals with the ‘mechanisms’ that may underpin the effect of cognitive behavioural therapies (CBT) or graded exercise.

Using very sophisticated statistical analysis, the researchers eventually conclude that ‘fear avoidance beliefs’ (that exercise will make symptoms worse) by the patient is a major factor in the success or otherwise of these therapies.

While this report may be fascinating to professional cognitive-behavioural theorists, the central fact remains – as the original PACE trial data showed (see our previous comment) – that the effects of these psychosocial approaches are modest, benefiting only around 10 to 15% of ME/CFS patients over and above the benefit of standard medical care (Table).

The majority are not helped back to health using these techniques, something confirmed time and time again when ME charities survey their members. As the Editorial accompanying this study says, most patients do not recover after these interventions, and “quite a few patients do not profit at all”. Indeed.

The tragedy is that every time one of these sub-analyses of PACE trial data is published, a rash of media stories trumpet its arrival. For instance, the Independent newspaper has headlined the “benefits of exercise”, while the Daily Mail goes for, “victims suffer fear of exercise” and the Daily Telegraph “ME: fear of exercise”. These stories are presumably based on the press release and run-off to satisfy the 24-hour news cycle, but they have little or no relevance to the real, lived experience of ME patients.

We all know that ME patients are highly motivated to get well, and more than willing to do whatever activity or exercise is appropriate for their personal circumstances, from a short walk to sitting up in bed. The notion of ‘fear avoidance’ seems inappropriate and absurd in this context, however fascinating the concept may be to academic psychologists.  [Posted on 15 Jan 2015]
