COVID-19 associated hospitalization in 571 patients with fibromyalgia-A population-based study

A Clinical Qualification Protocol Highlights Overlapping Genomic Influences and Neuro-Autonomic Mechanisms in Ehlers-Danlos and Long COVID-19 Syndromes

A substantial fraction of the 15% with double-jointedness or hypermobility have the traditionally ascertained joint-skeletal, cutaneous, and cardiovascular symptoms of connective tissue dysplasia and its particular manifestation as Ehlers-Danlos syndrome (EDS). The holistic ascertainment of 120 findings in 1261 EDS patients added neuro-autonomic symptoms like headaches, muscle weakness, brain fog, chronic fatigue, dyspnea, and bowel irregularity to those of arthralgia and skin laxity, 15 of these symptoms shared with those of post-infectious SARS-CoV-2 (long COVID-19). Underlying articulo-autonomic mechanisms guided a clinical qualification protocol that qualified DNA variants in 317 genes as having diagnostic utility for EDS, six of them identical (F2-LIFR-NLRP3-STAT1-T1CAM1-TNFRSF13B) and eighteen similar to those modifying COVID-19 severity/EDS, including ADAMTS13/ADAMTS2-C3/C1R-IKBKG/IKBKAP-PIK3C3/PIK3R1-POLD4/POLG-TMPRSS2/TMPRSS6-WNT3/WNT10A. Also, contributing to EDS and COVID-19 severity were forty and three genes, respectively, impacting mitochondrial functions as well as parts of an overlapping gene network, or entome, that are hypothesized to mediate the cognitive-behavioral, neuro-autonomic, and immune-inflammatory alterations of connective tissue in these conditions. The further characterization of long COVID-19 natural history and genetic predisposition will be necessary before these parallels to EDS can be carefully delineated and translated into therapies.

The possible onset of fibromyalgia following acute COVID-19 infection

INTRODUCTION

The exact pathogenesis of fibromyalgia (FM) syndrome is unclear. However, various infectious have been implicated with the development of FM after their acute phase. We aimed to investigate the incidence of FM syndrome among convalesced individuals following hospitalization for Acute Coronavirus Disease-2019 (COVID-19).

METHODS

We performed a cross-sectional study on patients who were discharged after COVID-19 hospitalization from the Sheba Medical Center, Israel, between July 2020 to November 2020. A phone interview was performed consisting of the following questionnaires: the Fibromyalgia Survey Diagnostic Criteria Questionnaire, Sense of Coherence Questionnaire to evaluate resilience, and the Subjective Traumatic Outlook Questionnaire to assess the associated psychological aspects of the trauma. The incidence of post-COVID FM was calculated and regression models were performed to identify predictors.

RESULTS

The study population consisted of 198 eligible patients who completed the phone interview. The median age was 64 (52-72) and 37% were women. The median follow-up was 5.2 months (IQR 4.4-5.8). The incidence of FM was 15% (30 patients) and 87% (172 patients) had at least one FM-related symptom. Female gender was significantly associated with post-COVID FM (OR 3.65, p = 0.002). In addition, high median Subjective Traumatic Outlook scores and low median Sense of Coherence scores were both significantly associated with post-COVID FM (OR 1.19, p<0.001 and OR 0.92, p<0.001, respectively).

CONCLUSIONS

FM is highly prevalent among COVID-19 convalescent patients. Our finding suggests that a significant subjective traumatic experience and a low resilience are highly associated with post-COVID FM.

The relationship between COVID-19 and fibromyalgia syndrome: prevalence, pandemic effects, symptom mechanisms, and COVID-19 vaccines

On March 11, 2020, the World Health Organization, realizing the level of spread worldwide and the severity of the condition, accepted coronavirus disease 19 (COVID-19) as a pandemic. Subsequently, quarantine conditions were implemented around the world, and these triggered particular results. Like all other individuals, fibromyalgia syndrome (FMS) patients were affected by these conditions. The stress load in pandemic conditions, difficulties in accessing healthcare services, changes in exercise compliance, variations in physiotherapy programs, and remote work conditions all had an impact on FMS patients. Although general expectations were negative, some FMS patients were able to manage the pandemic conditions and even turn them in their favor. This is thought to be due to this patient group having established strategies to cope with stress in the pre-pandemic period, and they had sufficient ability to adapt to changing situations. FMS-related symptoms occur in a subset of individuals following COVID-19. One of the factors is the increased psychological burden after COVID-19. There is evidence that neuroinflammatory pathways affect neuroplasticity in the central nervous system and trigger the onset of FMS-related symptoms. Among the probable mechanisms are alterations in inflammatory and anti-inflammatory pathways. Changes in the autonomic nervous system with the effect of SARS-CoV-2 may induce the emergence of FMS-related symptoms. FMS and COVID-19 can coexist, and FMS may create a tendency to vaccine hesitancy. Future studies should focus on elucidating FMS-related symptoms occurring post-COVID-19. There is a need to determine distinctions between the FMS clinical status that emerged following COVID-19 and the regular patient group in terms of diagnosis, treatment, and follow-up.

Evaluation of pain, disease activity, anxiety, depression, and neuropathic pain levels after COVID-19 infection in fibromyalgia patients

Background

Psychological stressors may cause mental disorders such as anxiety, depression, and post-traumatic stress disorders and fibromyalgia (FM) patients could be affected by these stressors.

Aim

To evaluate pain, disease activity, anxiety, depression, and neuropathic pain levels after COVID-19 infection in patients with FM.

Methods

According to the 2016 American College of Rheumatology (ACR) criteria, fifty-seven patients with FM alone and 77 patients with FM and recovering from COVID-19 infection were recruited to the study (group 1: patients with FM alone and group 2: patients with FM and recovering from COVID-19). Demographic and clinical characteristics were recorded. The pain level was determined by the Numerical Rating Scale (NRS), the pain regions by the Widespread Pain Index (WPI) of the 2016 ACR criteria, the severity of the symptoms by the Symptom Severity Scale (SSS) of the 2016 ACR criteria, the disease activity by the Fibromyalgia Impact Questionnaire (FIQ), the anxiety and depression levels by the Hospital Anxiety and Depression Scale (HADS), and the neuropathic pain level by Leeds Assessment of Neuropathic Symptoms and Signs Pain Scale (LANSS).

Results

Age, height, weight, Body Mass Index (BMI), and the duration of FM diagnosis were similar in both groups (p > 0.05). NRS, FIQ, HADS depression scale, and SSS and LANSS scores were similar between group 1 and group 2 (p > 0.05). HADS anxiety score and WPI were significantly increased in group 2 (p = 0.026 and p = 0.024 respectively).

Conclusions

Anxiety and widespread pain levels were higher in patients with FM and recovering from COVID-19 infection.
