Prevalence of fibromyalgia in fourteen Korean tertiary care university hospital pain clinics

Prevalence of FMS Diagnosis According to ACR 2016 Revised Criteria in a Pain Therapy Centre in Italy: Observational Study

Background and Objectives: Fibromyalgia syndrome (FMS) is a multifaceted disease with a strong preference for the female sex. It is characterised by chronic widespread pain, sleep-wake disorders, fatigue, cognitive disturbances, and several other somatic symptoms. Materials and Methods: In this prospective observational study, we analysed data regarding 302 patients who were referred to our pain centre for a first clinical assessment evaluation and were then inspected for the physician-based 2016 revision of the ACR diagnostic criteria for FMS, regardless of the final diagnosis previously made by the pain therapist. Results: Among the 280 patients who adhered to the 2016 ACR questionnaire, 20.3% displayed positive criteria for FMS diagnosis. The level of agreement between the FMS discharge diagnosis made by the pain clinician and the ACR 2016 criteria-positivity was moderate (kappa = 0.599, with moderate agreement set at a kappa value of 0.6). Only four patients (1.7%) diagnosed as suffering from FMS at discharge did not satisfy the minimal 2016 ACR diagnostic criteria. Conclusions: This prospective observational study confirmed the diagnostic challenge with FMS, as demonstrated by the moderate grade of agreement between the FMS diagnosis at discharge and the positivity for 2016 ACR criteria. In our opinion, the use of widely accepted diagnostic guidelines should be implemented in clinical scenarios and should become a common language among clinicians who evaluate and treat patients reporting widespread pain and FMS-suggestive symptoms. Further methodologically stronger studies will be necessary to validate our observation.

The current status of fibromyalgia in Korea: an electronic population health data study in Korea

Background

Fibromyalgia (FM) is a complex disorder characterized by widespread chronic pain and tenderness in the muscles, ligaments, and soft tissues. It is a chronic pain condition often accompanied by other symptoms and comorbidities. To effectively manage FM, it is crucial to obtain fundamental epidemiological data pertaining to the target population. Therefore, this study was conducted to elucidate the epidemiological characteristics of FM in the Korean population.

Methods

Population-based medical data of 51,276,314 subscribers to the National Health Insurance Service of Korea from 2014 to 2018 were used in this study.

Results

The overall incidence of FM ranged from 441 (2014) to 541 (2018) cases per 100,000 person-years, with a higher prevalence observed among female patients compared to male patients. The incidence gradually increased until middle age, followed by a decrease. The highest incidence rates were observed in the fifth decade of life for females and the sixth decade of life for males. When categorizing the affected parts of the body, the shoulder region was observed to be the most frequently affected. A comparison of the drug prescriptions based on medical specialty showed that antidepressants were the most commonly prescribed medications. The management of FM leads to consistent increases in medical expenses, regional disparities, and variations in prescription patterns across different medical specialties.

Conclusions

The findings of this study will not only contribute to the understanding of FM characteristics but also provide a vital foundation for efficient management of FM in Korea.

Prevalence and Characteristics of Fibromyalgia in Patients with Foot and Ankle Pain: The Experience of an Academic Podiatry Clinic

Background and Objectives: Research about the prevalence of fibromyalgia in podiatric patients is limited, with data suggesting potentially higher estimates and greater foot impairment in patients with fibromyalgia compared to healthy individuals. The aim of our study is to assess the prevalence of fibromyalgia in the podiatric healthcare setting and to research the characteristics of fibromyalgia patients with foot or ankle disorders. Materials and Methods: Consecutive patients visiting the academic podiatry clinic at the University of Bologna IRCCS Rizzoli Orthopaedic Institute between 11 January and 31 March 2021 were enrolled. Results: Of the 151 patients included, 21 met the fibromyalgia survey diagnostic criteria, accounting for a prevalence of 13.9% (95% CI 8.8-20.5). As part of the podiatric assessment, the Foot Function Index (FFI) was used to calculate the impact of foot and ankle problems. Moreover, patients with fibromyalgia were asked to complete the fibromyalgia impact questionnaire (FIQ). Fibromyalgia patients had significantly worse total FFI scores (63.4 ± 23.0% vs. 53.2 ± 20.3%, p = 0.038) and there was a significant linear correlation between the FFI and the FIQ (r = 0.72, p < 0.001). Conclusions: The prevalence of fibromyalgia in the academic podiatry clinic being 13.9% confirms that, in the healthcare setting, the disease can be more frequent than in the general population. Furthermore, our findings suggest a strong correlation between foot impairment and the impact of fibromyalgia.

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.

The Impact of Tinnitus on Fibromyalgia

Objective

Fibromyalgia (FM) is a disorder characterized by chronic diffuse pain and enhanced pain response to stimuli and is caused by central sensitization Tinnitus also is related to central sensitization So we investigated the impact of tinnitus on FM.

Methods

We included 22 FM patients with tinnitus and 25 FM patients without tinnitus We assessed a range of symptoms using the Widespread Pain Index; Symptom Severity Score scale; Visual Analogue Scale of pain; and the Korean versions of the Fibromyalgia Impact Questionnaire (FIQ), the Insomnia Severity Index, and the Short-form Health Survey (SF-36) Information about the severity of tinnitus in FM patients was evaluated using the Korean version of the Tinnitus Handicap Questionnaire (THQ-K).

Results

There were significant differences between the group that had mild tinnitus (THQ<38) and the group that had moderate-to-severe tinnitus (THQ≥38) for FIQ score (p=0025) and for the physical functioning (p=0003), social functioning (p=0035), and mental health (p=0017) components of the SF-36 Also, after dividing patients into 2 groups according to insomnia severity, significant differences were observed in FIQ score (p=0002) and in body pain (p=0001), general health (p=0008), vitality (p=0003), social functioning (p=0003), role limitation due to emotional condition (p=0001), and mental health (p<0001) components of the SF-36.

Conclusion

The FM patients with severe tinnitus had more functional impairments and lower quality of life than those with mild tinnitus Severe insomnia also was accompanied by worse health status and lower quality of life.

Burden of Illness Due to Fibromyalgia in a Neurology Clinic

Background  Fibromyalgia (FM) is a common disorder in general population and it causes an increased patient load in hospitals and specialty clinics. FM attendance will be high in clinics dealing with neuropathic pain and other pain syndromes. Though prevalence of FM has been studied in community and pain clinics in other countries, it has not so far been studied in India. So, a study is relevant and hence it was planned in neurology clinic of a teaching government hospital. At present, they are treated mainly by nonsteroidal anti-inflammatory drugs (NSAIDs) which are public health hazard. Methods  Using 2016 revision of 2010/2011 American College of Rheumatology criteria of FM, patients were screened in neurology OPD. Proportion and clinical profile were noted. Study was continued for 6 months till the sample size was met. Results  A total of 2,300 patients were screened. Two hundred and ninety-eight FM patients were identified among them. Proportion was 12.96%. Delayed diagnosis of more than a year occurred in 55%. Only 29.2% were treated, but none was offered cognitive behavioral therapy (CBT) before. NSAIDs for pain were given for 51.01%. Conclusion  Proportion of FM detected is considerable. Affection of homemakers and manual laborers, delayed diagnosis, coexisting comorbid illness, and treatment of pain with NSAIDs are causes of concern. Clinicians should be sensitized to clinical profile and criteria of FM. Patients should be diagnosed and treated by CBT at the earliest and NSAIDs should be avoided as far as possible.
