Psychosomatic Approach to Fibromyalgia Syndrome: Concept, Diagnosis and Treatment

Fibromyalgia syndrome (FMS) has chronic widespread pain (CWP) as a core symptom and a variety of associated somatic and psychological symptoms such as fatigue, sleep problems, cognitive disturbances, multiple somatic pain, and depression. FMS is the subject of considerable controversy in the realm of nosology, diagnosis, pathophysiology, and treatment.Moreover, the fact that FMS and mental illness are closely associated with each other might intensify the confusion for the distinction between FMS and mental disorders. This narrative literature review aims to provide the concept, diagnosis, and treatment of FMS from the integrative biopsychosocial and psychosomatic perspective. This article first explains the concepts of FMS as a disease entity of biopsychosocial model, and then summarizes the changes of diagnostic criteria over past three decades, differential diagnosis and comorbidity issue focused on mental illnesses. In addition, an overview of treatment of FMS is presented mainly by arranging the recommendations from the international guidelines which have been developed by four official academic associations.

Use of Ultrasonography to Discriminate Psoriatic Arthritis from Fibromyalgia: A Post-Hoc Analysis of the ULISSE Study

In psoriatic arthritis (PsA) patients with concomitant chronic widespread pain, the differential diagnosis with fibromyalgia syndrome (FMS) can be challenging. We evaluated whether ultrasound (US) examination of entheseal sites can distinguish pain from (PsA) enthesitis versus FMS. PsA and FMS patients underwent clinical evaluation and gray-scale (GS; B-mode) and power Doppler (PD) US examination of the entheses. At least one enthesis with GS- and PD-mode changes was found in 90% and 59.3% of PsA patients (n = 140) and 62.7% and 35.3% of FMS patients (n = 51), respectively. GS and PD identified changes in 49.5% and 19.2% of the 840 PsA entheses and 22.5% and 7.9% of the 306 FMS entheses, respectively. Receiver operating characteristic curve analysis showed an area under the curve of 0.77 and 0.66 for B- and PD-mode, respectively, 3.5 being the best cut-off GS-score to discriminate the two conditions. Multivariate regression showed that Achilles and proximal patellar tendon enthesitis (B-mode) were strongly associated with PsA (odds ratio, ~2). Principal component analysis (B-mode) confirmed that PsA patients have a higher number of involved entheses and patterns of entheseal involvement than FMS patients. US evaluation of the entheses may help differentiate chronic widespread pain from PsA versus FMS.

Fibromyalgia: transformation of views

Fibromyalgia (FM) is a mystery of modern rheumatology. Despite the high prevalence of FM according to special epidemiological studies, clinicians make this diagnosis rarely. The modern concept of fibromyalgia was created by Smythe and Moldofsky in the mid-70s. They introduced a new term «fibromyalgia», thereby emphasizing that this condition is more due to pain syndrome than inflammation of connective tissue. A disturbance of sensory information processing in the central nervous system (dysfunction of the pain system with the formation of central sensitization, CS) plays a key role in the pathogenesis of FM. Clinical manifestations of FM include chronic widespread pain associated with a wide range of psychosomatic disorders (sleep disorders, cognitive disorders [fibro fog], anxiety, depression, fatigue, morning stiffness, etc.). The diagnostic criteria for fibromyalgia have undergone significant changes. The latest FM diagnostic criteria were developed by the American College of Rheumatology (ACR) in 2016. According to the ACR (2016) FM criteria, a diagnosis of FM does not exclude the presence of other clinically important illnesses. Concomitant FM among patients with rheumatic diseases (RD) occurs 2–3 times more often than in the general population. Diagnostics and treatment of FM are extremely difficult for clinicians, it is especially difficult with comorbidity of FM with RD. Therefore, FM requires a multidisciplinary approach within a biopsychosocial model of pain syndrome: the treatment of a patient with RD and FM should combine anti-inflammatory therapy with a complex of methods (medications and nondrug therapy) used for FM therapy. The diagnostics of comorbid FM in patients with RD will allow for personalized and more effective analgesic therapy.

Prognostic factors for work disability in patients with chronic widespread pain and fibromyalgia: protocol for a cohort study

IntroductionThe association between chronic widespread pain (CWP) and disability is well established. Although research support large interindividual differences in functional outcomes, limited studies are available on the socio-economic consequences of offering stratified treatment based on prognostic factors. Identification of predictors of long-term functional outcomes such as work disability as a critical consequence, could assist early and targeted personalised interventions. The primary objective of this cohort study is to identify prognostic factors for the primary endpoint work status (employed and working vs not working) in patients with CWP assessed 3 years from baseline, that is, at referral for specialist care.Methods and analysesData are collected at the diagnostic unit at Department of Rheumatology, Frederiksberg Hospital. The first 1000 patients ≥18 years of age registered in a clinical research database (DANFIB registry) with CWP either ‘employed and working’ or ‘not working’ will be enrolled. Participants must meet the American College of Rheumatology 1990 definition of CWP, that is, pain in all four body quadrants and axially for more than 3 months and are additionally screened for fulfilment of criteria for fibromyalgia. Clinical data and patient-reported outcomes are collected at referral (baseline) through clinical assessment and electronic questionnaires. Data on the primary endpoint work status at baseline and 3 years from baseline will be extracted from the Integrated Labour Market Database, Statistics Denmark and the nationwide Danish DREAM database. Prognostic factor analysis will be based on multivariable logistic regression modelling with the dichotomous work status as dependent variable.Ethics and disseminationSensitive personal data will be anonymised according to regulations by the Danish Data Protection Agency, and informed consent are obtained from all participants. Understanding and improving the prognosis of a health condition like CWP should be a priority in clinical research and practice. Results will be published in international peer-reviewed journals.Trial registration numberNCT04862520.

Testing a newly developed activity pacing framework for chronic pain/fatigue: a feasibility study

ObjectivesTo test the feasibility of using a new activity pacing framework to standardise healthcare professionals’ instructions of pacing, and explore whether measures of activity pacing/symptoms detected changes following treatment.DesignSingle-arm, repeated measures study.SettingOne National Health Service (NHS) Pain Service in Northern England, UK.ParticipantsAdult patients with chronic pain/fatigue, including chronic low back pain, chronic widespread pain, fibromyalgia and chronic fatigue syndrome/myalgic encephalomyelitis.InterventionsSix-week rehabilitation programme, standardised using the activity pacing framework.Outcome measuresFeasibility was explored via patients’ recruitment/attrition rates, adherence and satisfaction, and healthcare professionals’ fidelity. Questionnaire data were collected from patients at the start and end of the programme (T1 and T2, respectively) and 3 months’ follow-up (T3). Questionnaires included measures of activity pacing, current/usual pain, physical/mental fatigue, depression, anxiety, self-efficacy, avoidance, physical/mental function and quality of life. Mean changes in activity pacing and symptoms between T1-T2, T2-T3 and T1-T3 were estimated.ResultsOf the 139 eligible patients, 107 patients consented (recruitment rate=77%); 65 patients completed T2 (T1-T2 attrition rate=39%), and 52 patients completed T3 (T1-T3 attrition rate=51%). At T2, patients’ satisfaction ratings averaged 9/10, and 89% attended ≥5 rehabilitation programme sessions. Activity pacing and all symptoms improved between T1 and T2, with smaller improvements maintained at T3.ConclusionThe activity pacing framework was feasible to implement and patients’ ability to pace and manage their symptoms improved. Future work will employ a suitable comparison group and test the framework across wider settings to explore the effects of activity pacing in a randomised controlled trial.Trial registration numberNCT03497585.

Prolonged standing behaviour in people with joint hypermobility syndrome

Background Joint Hypermobility Syndrome (JHS) is a rare Heritable Disorder of Connective tissue characterised by generalised joint laxity and chronic widespread pain. Joint Hypermobility Syndrome has a large impact on patients’ day to day activities, and many complain of symptoms when standing for prolonged periods. This study investigates whether people with JHS exhibit the same behaviours to deal with the effects of prolonged standing as people with equal hypermobility and no pain, and people with normal flexibility and no pain. Methods Twenty three people with JHS, 22 people with Generalised Joint Hypermobility (GJH), and 22 people with normal flexibility (NF) were asked to stand for a maximum of 15 min across two force-plates. Fidgets were counted and quantified using a cumulative sum algorithm and sway parameters of the quiet standing periods between fidgets were calculated. Results Average standing time for participants with JHS was 7.35 min and none stood for the full 15 min. All participants with GJH and NF completed 15 min of standing. There were no differences in fidgeting behaviour between any groups. There was a difference in anteroposterior sway (p = .029) during the quiet standing periods. Conclusion There is no evidence to suggest people with JHS exhibit different fidgeting behaviour. Increased anteroposterior-sway may suggest a muscle weakness and strengthening muscles around the ankle may reduce postural sway and potentially improve the ability to stand for prolonged periods.

Comparison of chronic widespread pain prevalence with different criteria in two cohorts of rheumatoid arthritis

Objective This study aims to investigate chronic widespread pain with the 1990 (CWP1990) and 2019 (CWP2019) definitions 6 years after the onset of rheumatoid arthritis (RA), in one patient cohort with tight controls and one conventional cohort, and factors associated with reporting CWP1990 and CWP2019, respectively. Methods A cohort of 80 RA patients with monthly visits to the physician the first 6 months was compared to a cohort of 101 patients from the same clinic with conventional follow-up. Both cohorts had early RA (< 13 months). The prevalence of CWP1990 and the more stringent CWP2019 were in a 6-year follow-up investigated with a questionnaire, including a pain mannequin and a fear-avoidance beliefs questionnaire. Results In the tight control cohort, 10% reported CWP2019 after 6 years compared to 23% in the conventional cohort (p = 0.026). There was no difference when using the CWP1990 definition (27% vs 31%, p = 0.546). When adjusted for important baseline data, the odds ratio for having CWP2019 was 2.57 (95% CI 1.02–6.50), in the conventional group compared to the tight control group (p = 0.046). A high level of fear-avoidance behaviour towards physical activity was associated with CWP2019, OR 10.66 (95% CI 1.01–112.14), but not with CWP1990 in the tight control cohort. Conclusion A more stringent definition of CWP identifies patients with a more serious pain condition, which potentially could be prevented by an initial tight control management. Besides tight control, caregivers should pay attention to fear-avoidance behaviour and tailor treatment. Key Points • CWP2019 is a more stringent definition of chronic widespread pain and identifies patients with a more serious pain condition. • Patients with a serious pain condition could be helped by frequent follow-ups. • This study suggests that a special attention of fear-avoidance behaviour towards physical activity in patients with RA is needed.

The Association of Pain Levels and Low Physical Activity among Older Women

There is an integral research gap regarding whether there is a relationship between pain levels and low physical activity among older women. This is a secondary analysis of a longitudinal cohort study, the Women’s Health and Aging Study (WHAS) II. Our analyses included 436 community-dwelling women between the ages of 70 and 79, who were followed for 10.5 years. We employed marginal structural modeling, which controls for time-dependent confounding, with the aim of assessing the potential direct association between pain levels and low physical activity and assess a graded relationship. Compared to women with no pain, those with widespread pain were nearly half as likely to be moderately active versus low active (aOR: 0.46, 95% confidence interval (CI): 0.22, 0.96). A graded association was observed across the four pain levels (no pain or mild pain, other pain, moderate or severe lower extremity pain, and widespread pain) on low physical activity. Our findings indicate that reducing chronic widespread pain in older women may increase moderate physical activity, and therefore reduce the downstream health risks of physical inactivity, including morbidity and mortality risk.

Prevalence of Depression among Patients with Chronic Painful Physical Condition and Its Association with Quality of Life

Background & Purpose: Some studies have reported associations between depression and pain syndrome. An epidemiological study in the UK reported that 16.9% of participants with chronic widespread pain also had a psychiatric diagnosis. Purpose of the present study is to know the prevalence of depression among Patients with Chronic Painful Physical condition & to find out association between depression & quality of life among patients with chronic painful physical condition. Methodology: 120 patients with chronic painful physical condition who met inclusion criteria were recruited from SPB Physiotherapy OPD. Written informed consent was taken. All the participants were asked to fill up the Beck’s depression inventory (BDI) to determine the prevalence of Depression and the 36-item short form health survey (SF-36) for quality of life assessment. Results: Among 120 participants 63 (52.5%) participants were reported mild to moderate depression. Result of spearman’s test suggested moderate negative correlation (r = -0.41, P = 0.00943) between depression and quality of life among participants with Chronic Painful Physical Condition. Conclusion: The present study concluded that 52.5% patients with chronic painful physical condition have mild to moderate symptoms of depression and there is moderate negative co-relation exist between depression and quality of life among them. Key words: Depression, Painful Physical Condition, SF36, BDI, Quality of Life.
