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.
Autoimmune/inflammatory Syndrome Induced by Adjuvants (ASIA; Shoenfeld’s syndrome) comprehends a group of autoimmune conditions that flourish in genetically predisposed individuals, following an external stimulus by the so-called adjuvants. Many adjuvants were described, such as vaccines, aluminum and other metals, silicone, tattoos, among others. Those conditions entail defined diseases, such as sarcoidosis and Sjogren’s syndrome, and generalized complex symptoms, for example, fatigue, sleep disturbance, orthostatic intolerance, and other dysautonomic manifestations. Those complaints were previously associated with autoantibodies against nervous system autonomic receptors, especially antibeta 1 adrenergic receptor antibodies, suggesting the autoimmune component of the condition. Here we report on a case of an 18-year-old woman who presented with extreme cachexia due to severe dysautonomia caused by the ASIA syndrome induced by the tetanus, diphtheria, and pertussis vaccine (Tdap).
BackgroundIn an age of dose optimization and drug tapering due to excellent conventional (c), biological (b) or targeted synthetic (ts) disease-modifying anti-rheumatic drugs (DMARDs), the fact remains that many patients still have active disease, being therapy refractory, sometimes to multiple DMARDs. In 2021, EULAR defined the term “Difficult-to-treat (D2T) Rheumatoid Arthritis” as failure of two or more different classes of b/tsDMARDs post csDMARDs (1) but the rate of failure to all available DMARD classes in the real-world setting (poly-refractory RA) is not established. Moreover, the DAS-28-CRP score can be elevated in patients with either persistent inflammatory RA (PIRRA) or non-inflammatory RA (NIRRA), where the latter do not benefit from medication change [2]. PIRRA patients have at least one clinically swollen joint, with objective evidence of active inflammation in power Doppler ultrasound (PDUS), often with elevated CRP levels, whilst NIRRA patients have apparent clinical swelling but absence of PDUS and often normal CRP levels.ObjectivesThis study determined the prevalence of EULAR-defined refractory RA (D2T RA) in Leeds. Secondly, we established the prevalence of poly-refractory RA, i.e., patients that failed all available b/tsDMARD classes. Finally, we determined NIRRA/PIRRA phenotypes in refractory disease.Methods1591 RA patients receiving b/ts DMARDs therapy between 2018-2022 were identified as part of a service evaluation, excluding those where DAS-28-CRP was unavailable. Patients fulfilling EULAR-ACR criteria for D2T RA, with DAS-28-CRP≥ 3.2 and US imaging where available were evaluated. Patients were further divided into NIRRA and PIRRA, according to the presence/absence of signs of active synovitis as indicated by PDUS (Figure 1).Results242/1591 (15.2%) met the EULAR D2T criteria of failing at least 2 b/tsDMARDs. 89/1591 (5.6%) failed 2 classes only, with a mean disease duration (mDD) of 11 years. 60/1591 (3.8%) failed 3 classes (mDD= 18) and 52/1591 (3.3%), 4 classes (mDD= 10.5). However, just 41/1591 (2.5%) had poly-refractory RA having failed all 5 classes (mDD= 21). Of them, 37/41 (90%) failed multiple drugs within each class. 4/41 (10%) poly-refractory and 45/242 (18.5%) of all EULAR D2T cases were seronegative. Regarding joint involvement patterns, most had typical small joint RA disease pattern but 26/242 (11%) had a predominant large joint pattern. 18/41 (43%) of the poly-refractory RA group had CRP levels within the normal ranges despite a DAS-28-CRP score above 3.2 (mean DAS-28-CRP of 5.3). 71 D2T RA patients had recent US of clinically involved joints, including 28 poly-refractory RA cases. 18/28 (64%) poly-refractory were considered PIRRA as evidenced by synovial hypertrophy and PDUS positivity in at least one evaluated clinically swollen joint. 32/71 (45%) D2T RA had no signs of active synovitis in PDUS being considered NIRRA. Of them, 17/32 (53%) had no synovial thickening in US in suspected clinically involved joints. Specifically in the poly-refractory group, the CRP levels were within normal ranges in 6/10 (60%) NIRRA patients, while just 7/18 (39%) PIRRA cases had normal CRP levels.ConclusionAlthough 15.2% of Leeds RA patients met the EULAR criteria for D2T RA, real world poly-refractory RA was present in only 2.5%. Almost half of these patients had no PDUS changes on US and/or had normal CRP levels. These findings highlight a twofold clinical challenge in refractory RA with half of this group (both D2T and poly-refractory RA) having true inflammation that may need new mechanisms of action, but the other half would not be likely to benefit from new DMARD treatment strategies.References[1] Nagy G, Roodenrijs NM, Welsing PM et al.
