Not the Last Word: Fibromyalgia is Real

Aetiological Understanding of Fibromyalgia, Irritable Bowel Syndrome, Chronic Fatigue Syndrome and Classificatory Analogues: A Systematic Umbrella Review

Background

This umbrella review systematically assesses the variety and relative dominance of current aetiological views within the scientific literature for the three most investigated symptom-defined functional somatic syndromes (FSS) and their classificatory analogues within psychiatry and psychology.

Method

An umbrella review of narrative and systematic reviews with and without meta-analyses based on a search of electronic databases (PubMed, Web of Science, Embase, PsychINFO) was conducted. Eligible reviews were published in English, focused on research of any kind of aetiological factors in adults diagnosed with fibromyalgia syndrome (FMS), irritable bowel syndrome (IBS), chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME), and somatic symptom disorder (SSD)/somatoform disorder (SFD).

Results

We included 452 reviews (132 systematic reviews including meta-analyses, 133 systematic reviews, 197 narrative reviews), of which 132 (29%) focused on two or more of the investigated health conditions simultaneously. Across diagnoses, biological factors were addressed in 90% (k = 405), psychological in 33% (k = 150), social in 12% (k = 54), and healthcare factors in 5% (k = 23) of the reviews. The methodological quality of the included systematic reviews (k = 255) was low (low/critically low: 41% [k = 104]; moderate: 49% [k = 126]; high quality: 10% [k = 25]). The high-quality systematic reviews suggest that deficient conditioned pain modulation, genetic factors, changes in the immune, endocrinological, gastrointestinal, cardiovascular, and nervous system, and psychosocial factors such as sexual abuse and pain catastrophizing increase the risk for FSS.

Conclusion

Only very few systematic reviews have used comprehensive, biopsychosocial disease models to guide the selection of aetiological factors in FSS research. Future research should strive for higher scientific standards and broaden its perspective on these health conditions.

Epistemic Injustice and Nonmaleficence

Epistemic injustice has undergone a steady growth in the medical ethics literature throughout the last decade as many ethicists have found it to be a powerful tool for describing and assessing morally problematic situations in healthcare. However, surprisingly scarce attention has been devoted to how epistemic injustice relates to physicians' professional duties on a conceptual level. I argue that epistemic injustice, specifically testimonial, collides with physicians' duty of nonmaleficence and should thus be actively fought against in healthcare encounters on the ground of professional conduct. I do so by fleshing out how Fricker's conception of testimonial injustice conflicts with the duty of nonmaleficence as defined in Beauchamp and Childress on theoretical grounds. From there, I argue that testimonial injustice produces two distinct types of harm, epistemic and non-epistemic. Epistemic harms are harms inflicted by the physician to the patient qua knower, whereas non-epistemic harms are inflicted to the patient qua patient. This latter case holds serious clinical implications and represent a failure of the process of due care on the part of the physician. I illustrate this through examples taken from the literature on fibromyalgia syndrome and show how testimonial injustice causes wrongful harm to patients, making it maleficent practice. Finally, I conclude on why nonmaleficence as a principle will not be normatively enough to fully address the problem of epistemic injustice in healthcare but nevertheless may serve as a good starting point in attempting to do so.

Patients With Functional Somatic Syndromes-Fibromyalgia, Irritable Bowel Syndrome, Chronic Headaches, and Chronic Low Back Pain-Have Lower Outcomes and Higher Opioid Usage and Cost After Shoulder and Elbow Surgery

PURPOSE

To perform a systematic review assessing the relationship between functional somatic syndromes (FSSs) and patient-reported outcome measures (PROMs), postoperative opioid consumption, and hospitalization costs after shoulder and elbow surgery.

METHODS

A systematic review of the PubMed and Web of Science databases was conducted according to Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines to identify all studies evaluating the effect of having at least 1 FSS (fibromyalgia, irritable bowel syndrome, chronic headaches, chronic low back pain) on outcomes after shoulder and elbow surgeries. Outcomes of interest included postoperative analgesic use, PROMs, and hospitalization costs.

RESULTS

The review identified a total of 320 studies, of which 8 studies met the inclusion criteria. The total number of participants in our 8 included studies was 57,389. Three studies (n = 620) reported PROMs. These studies demonstrated that the presence of at least 1 FSS is predictive of significantly greater pain scores and lower quality of recovery, Disability Arm Shoulder and Hand, American Shoulder and Elbow Surgeons Shoulder Score, and Single Assessment Numeric Evaluation scores postoperatively. Although scores were inferior in among patients with FSS, 2 of the 3 studies showed improvement in PROMs in this group of patients. Seven studies (n = 56,909) reported postoperative opioid use. Of these, 5 reported that a diagnosis of at least 1 FSS was a strong risk factor for long-term opioid use after surgery. One study (n = 480) found that time-driven activity-based costs were significantly greater in patients with FSSs.

CONCLUSIONS

Patients with functional somatic syndromes have less-favorable PROMs postoperatively, consume more opioids postoperatively, and have greater health care costs after elective shoulder and elbow procedures. Although PROMs among patients with FSSs are inferior compared with those without FSSs, PROMs still improved compared with baseline.

LEVEL OF EVIDENCE

Level III, systematic review of Level II-III studies.

Constructing the Gendered Risk of Illness in Lyrica Ads for Fibromyalgia: Fear of Isolation as a Motivating Narrative for Consumer Demand

Direct-to-consumer television advertisements for Lyrica in the United States create narratives of gendered domestic normalcy to which women with fibromyalgia are encouraged to aspire through pharmaceutical intervention. This paper unpacks images and narratives within these advertisements to demonstrate that they rely on metaphors that represent gendered expectations in order to evoke guilt and provoke a desire for what Joseph Dumit calls "health as risk reduction," and what I argue is an attempt to show disability being erased. Following Stuart Hall's Encoding/Decoding model of communication, viewers play a role in constructing societal expectations for women with chronic pain and for themselves.

Functional somatic syndromes are associated with suboptimal outcomes and high cost after shoulder arthroplasty

BACKGROUND

The presence of functional somatic syndromes (chronic physical symptoms with no identifiable organic cause) in patients undergoing elective joint arthroplasty may affect the recovery experience. We explored the prevalence of functional somatic syndromes among shoulder arthroplasty patients, as well as their association with postoperative outcomes and costs.

METHODS

We identified 480 patients undergoing elective total shoulder arthroplasty (anatomic or reverse) between 2015 and 2018 in our institutional registry with minimum 2-year follow-up. Medical records were queried for the presence of 4 well-recognized functional somatic syndromes: fibromyalgia, irritable bowel syndrome, chronic headaches, and chronic low-back pain. Multivariable linear regression modeling was used to determine the independent association of these diagnoses with hospitalization time-driven activity-based costs and 2-year postoperative American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation (SANE), and pain scores.

RESULTS

Nearly 1 in 5 patients (17%) reported at least 1 functional somatic syndrome. These patients were more likely to be women, to be chronic opioid users, to report more allergies, to have a diagnosis of anxiety, and to have shoulder pathology other than degenerative joint disease (all P ≤ .001). After multivariable adjustment, the presence of at least 1 functional somatic syndrome was independently predictive of lower 2-year ASES (-9.75 points) and SANE (-7.63 points) scores and greater residual pain (+1.13 points) (all P ≤ .001). When considered cumulatively, each additional functional disorder was linked to a stepwise decrease in ASES and SANE scores and an increase in residual pain (P < .001). These patients also incurred higher hospitalization costs, with a stepwise rise in costs with an increasing number of disorders (P < .001).

CONCLUSIONS

Functional somatic syndromes are common in patients undergoing shoulder arthroplasty and correlate with suboptimal outcomes and greater resource utilization. Efforts to address the biopsychosocial determinants of health that affect the value proposition of shoulder arthroplasty should be prioritized in the redesign of care pathways and bundling initiatives.

Fibromyalgia in Primary Care

Fibromyalgia is a common disorder and has substantial impact on quality of life. The cause remains unknown, but current evidence points to multifactorial involvement of pain processing. Clinical diagnosis is aided by evidence-based diagnostic criteria with subscores for widespread pain and symptom severity. Nonpharmacologic treatments, including cognitive behavioral therapy, sleep hygiene, and regular aerobic exercise, form the cornerstone of management. Pharmacologic intervention is an important adjunct, but benefit is variable. There is no cure for fibromyalgia at this time, but persistence and patience in management may lead to a satisfactory lifestyle.
