Defining and measuring recovery from myalgic encephalomyelitis and chronic fatigue syndrome: the physician perspective

Abstract:

Purpose: To inform an operationalised definition of recovery from myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS) for research and practice. Without a consensus on defining and measuring recovery, there will continue to be controversy amongst researchers, clinicians, and patients when interpreting treatment outcomes.

Method: This study explores physicians’ views on recovery from ME and CFS. We conducted semi-structured interviews with 10 physician participants who are experts in the ME and CFS field. Our deductive thematic analysis, using a realist perspective, provided a framework for differentiating recovery and significant improvement.

Results: Physicians conceptualised recovery as complete symptom remission and a return to premorbid functioning (adjusted for with age), whereas they viewed significant improvement as a substantial reduction in symptoms with considerable functional gains, where patients may operate in daily life but still must cope or be treated.

Conclusions: Our findings provide recommendations and approaches for measuring: daily functioning, symptomatology, quality of life, and physical functioning.

  • Implications for rehabilitation
  • Physicians viewed recovery as complete symptom remission and a return to premorbid functioning (adjusted for with age).
  • Recovery from myalgic encephalomyelitis and chronic fatigue syndrome should be viewed as multidimensional, considering patients’ daily life, psychosocial functioning, and overall physical functioning.
  • These findings can improve practitioner-client interactions, as they provide recommendations for measuring recovery in research and practice.

To Serve or Not to Serve: Ethical and Policy Implications

Abstract:

The Institute of Medicine (IOM) is one of the nation’s more influential health-related non-profit organizations. It plays a large role in shaping health policy by commissioning panels to develop “white papers” describing research and recommendations on a variety of health topics. These white paper publications are often used to help make policy decisions at the legislative and executive levels. Such a prominent institution might seem like a natural ally for policy-related collaborative efforts. As community psychologists, we strongly endorse efforts to positively influence public policy at the national level. However, while serving on influential panels and commissions like the IOM might seem to be very much part of the ethos of our discipline, there are occasions when such institutions are pursuing a mission that inadvertently has the potential to instigate divisive friction among community activists and organizations.

A case study is presented whereby I describe my decision not to accept an invitation to serve on a controversial IOM panel. I explore the ethical challenges regarding maintaining my independence from this institution and its attempt to redefine chronic fatigue syndrome (CFS) and myalgic encephalomyelitis (ME), as well as the process of searching for alternative avenues for collaborating with community activists to influence policy related to these debilitating illnesses.

The PACE trial missteps on pacing and patient selection

Abstract:

As others have pointed out a variety of complicating factors with the PACE trial (e.g. changing outcome criteria), I will limit my remarks to issues that involve the composition of adaptive pacing therapy and issues involving patient selection. My key points are that the PACE trial investigators were not successful in designing and implementing a valid pacing intervention and patient selection ambiguity further compromised the study’s outcomes.

A Prospective Study of Infectious Mononucleosis in College Students

Abstract:

BACKGROUND: The present study aims to prospectively investigate possible biological and psychological factors present in college students who will go on to develop chronic fatigue syndrome (CFS) following Infectious Mononucleosis (IM). Identification of risk factors predisposing patients towards developing CFS may help to understand the underlying mechanisms and ultimately prevent its occurrence. Our study is enrolling healthy college students over the age of 18. Enrollment began in March of 2013 and is ongoing.

METHODS: Biological and psychological data are collected when students are well (Stage 1), when they develop IM (Stage 2), and approximately 6 months after IM diagnosis (Stage 3).

RESULTS: Two case studies demonstrate the progression of student symptomology across all three stages.

CONCLUSION: The Case Studies presented illustrate the usefulness of a prospective research design that tracks healthy students, following their trajectory of IM illness to either a) full recovery or b) diagnosis with CFS.

Access to Medical Care for Individuals with Myalgic Encephalomyelitis and Chronic Fatigue Syndrome: A Call for Centers of Excellence

Abstract:

The current study sought to better understand the experience of individuals with myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS) in accessing care for their debilitating illness. Of 898 participants, less than half had ever seen an ME or CFS specialist, though 99% of participants were interested in specialist care. Participants cited geographic and financial barriers as most frequently precluding access to specialists. Furthermore, satisfaction with specialist care greatly exceeded satisfaction with non-specialist care. These findings suggested that individuals with ME and CFS represent a medically-underserved population, due to lack of available care. The CFS Advisory Committee and NIH Pathways to Prevention Working Group recommended the creation of ME and CFS Centers of Excellence to improve the healthcare access of patients with ME and CFS. The current study documents the need for these centers, as they would ameliorate geographic and financial barriers to quality care.

Subtyping Patients with Myalgic Encephalomyelitis (ME) and Chronic Fatigue Syndrome (CFS) By Course of Illness

Abstract:
Past research has subtyped patients with Myalgic Encephalolyelitis (ME) and Chronic Fatigue Syndrome (CFS) according to factors related to illness onset, illness duration, and age. However, no classification system fully accounts for the wide range of symptom severity, functional disability, progression, and prognosis seen among patients. This study examined whether illness trajectories among individuals with CFS were predictive of different levels of symptomology, functional disability, and energy expenditure.
Of the participants (N=541), the majority described their illness as Fluctuating (59.7%), with 15.9% Constantly Getting Worse, 14.1% Persisting, 8.5% Relapsing and Remitting, and 1.9% Constantly Getting Better. The illness courses were associated with significant differences in symptomology on select domains of the DSQ, functioning on select subscales of the SF-36, and on overall levels of energy expenditure.
The significant symptomatic and functional differences between groups suggest that subtyping patients with CFS according to illness course is a promising method for creating more homogeneous groups of patients.

Post-Exertional Malaise in Patients with ME and CFS with Comorbid Fibromyalgia

Abstract:

BACKGROUND: Myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS) share some similar symptoms with fibromyalgia (FM). Prior research has found increased illness severity when patients have FM that is comorbid with ME and CFS. For example, post-exertional malaise (PEM) has been shown to be more severe in those with comorbid FM. However, PEM can be separated into two factors, Muscle and General PEM. It is unknown if the more severe PEM findings in comorbid FM are due to the Muscle or General PEM factor.

PURPOSE:The purpose of this study was to determine if the PEM differences seen between patients with and without comorbid FM exist for the Muscle or General PEM factors.

METHOD: An international convenience sample was collected via an online questionnaire. The questionnaire assessed the frequency and severity of several PEM-related symptoms. Additionally, participants provided information regarding the course and characteristics of their illness.

RESULTS: Participants that indicated a comorbid diagnosis of FM displayed significantly more frequent and severe PEM symptoms in the Muscle and General PEM factors. The FM group also indicated significantly worse physical functioning compared to the group without comorbid FM.

DISCUSSION: The secondary diagnosis of FM in addition to ME and CFS appears to amplify the PEM symptomatology and worsen patients' physical functioning. The findings of this study have notable implications on the inclusion of patients with comorbid FM in ME and CFS research studies.

A Comparison of Case Definitions for Myalgic Encephalomyelitis and Chronic Fatigue Syndrome

Abstract:

Many professionals have described the clinical presentation of myalgic
encephalomyelitis (ME), but recent efforts have focused on the development of ME
criteria that can be reliably applied. The current study compared the symptoms and
functioning of individuals who met the newly-developed Institute of Medicine (IOM)
clinical criteria to a revised version of the London criteria for ME. While 76% of a
sample diagnosed with chronic fatigue syndrome (CFS) met the IOM criteria, 44%
met the revised London criteria. The revised London criteria identified patients with
greater physical impairment. The results of this study indicate the need for a standard
case definition with specific guidelines for operationalization. The application of case
definitions has important implications for the number of individuals identified with ME,
the pattern of symptoms experienced by these individuals, and the severity of their
symptoms and functional limitations. Sample heterogeneity across research studies
hinders researchers from replicating findings and impedes the search for biological
markers and effective treatments.

Dysregulation of cytokine pathways in chronic fatigue syndrome and multiple sclerosis

Abstract:

Background: Cytokine studies in chronic fatigue syndrome (CFS) have yielded mixed findings.

Purpose: This investigation evaluated whether network analysis of cytokine production differs between patients with CFS and multiple sclerosis (MS) as compared to a reference group of healthy controls.

Methods: Three subgroups (N = 109) were included: 15 participants who met diagnostic criteria for CFS, 57 participants meeting criteria for MS, and 37 controls. Peripheral blood was obtained and production of a select cytokine profile was determined from stimulated and unstimulated mononuclear cells. Data were generated through the use of a multi-analyte bead suspension array. Pairwise associations were determined for each group, and these associations were used to create a graphical representation of the data. The graph was clustered using an eigenvector community algorithm and results visualized using edges to model the correlations by color and thickness to show direction and strength.

Results: The control and MS groups produced a three-neighborhood relationship regardless of cell condition. While producing a three-neighborhood relationship, the MS group differed significantly from the control group as it displayed stronger relationships among pro-inflammatory cytokines. In contrast, the CFS group displayed a three-neighborhood solution when unstimulated. However, when cells from the CFS group were stimulated, a two-neighborhood model was found that exhibited stronger inter-cytokine correlations. The model found in CFS was significantly different from that found in the control and MS groups.

Conclusion: CFS was characterized by a pattern of global immunologic activation using network analysis, fundamentally different from those found for either MS or control groups.
