Polymyalgia Rheumatica Following COVID-19 Vaccination.

We herein report a 71-year-old woman presented with a fever, arthralgia, general malaise and leg muscle stiffness following administration of the COVID-19 mRNA vaccine (Comirnaty, Pfizer-BioNTech). Laboratory findings showed an elevated C-reactive protein level and erythrocyte sedimentation rate. In addition, Gallium-67 scintigraphy demonstrated an increased uptake in multiple joints. Typing of human leukocyte antigen (HLA) revealed the presence of the DRB1*0404/*0803 allele. These findings met the diagnostic criteria for polymyalgia rheumatica (PMR), and when we started steroid treatment, her symptoms improved rapidly. This patient developed PMR after receiving a COVID-19 mRNA vaccine (Comirnaty, Pfizer-BioNTech). This case is considered to be valuable, as the HLA-DRB1 allele was also confirmed.

COVID-19 outcomes in giant cell arteritis and polymyalgia rheumatica versus rheumatoid arthritis: A national, multicenter, cohort study.

OBJECTIVES: To determine whether giant cell arteritis and polymyalgia rheumatica (GCA/PMR) represent independent risk factors for worse outcomes in COVID-19. METHODS: Observational, national, French, multicenter cohort (NCT04353609) comprising patients aged ≥18 years with confirmed diagnoses of either GCA, PMR or rheumatoid arthritis (RA) having presented COVID-19; those under rituximab were excluded. Primary endpoint was COVID-19 severity in GCA/PMR patients as compared to RA. We also aimed to describe the evolution of GCA/PMR patients following COVID-19. Multinomial logistic regression models were performed, with and without adjustment on pre-specified confounding factors (i.e., age, sex, body mass index, arterial hypertension, diabetes and cardiovascular disease). Unadjusted and adjusted multinomial odds-ratio (OR/aOR) and their 95% confidence intervals (CIs) were calculated as effect size using RA as reference group. RESULTS: Between April 15, 2020, and August 20, 2021, 674 patients [45 (6.6%) GCA, 47 (7.0%) PMR, 582 (86.4%) RA; 62.8 years, 73.2% female] were included. Compared to RA patients, those with GCA/PMR were older and more frequently presented hypertension, diabetes and cardiovascular disease. Severe COVID-19 and death occurred in 24 (26.1%) and 16 (17.8%) patients with GCA/PMR, respectively. Unadjusted analyses revealed higher odds of severe COVID-19 [OR = 3.32 (95% CI 1.89-5.83; p < 0.001)] and death [OR = 3.20 (95%CI 1.67-6.13; p < 0.001)] for GCA/PMR compared to RA. After model adjustment, these odds were attenuated. CONCLUSION: Patients with GCA/PMR were more likely to have severe COVID-19 and higher mortality compared to those with RA. This worse prognosis is mostly due to well known risk factors for the general population rather than vasculitis per se.

Self-limited Polymyalgia Rheumatica-like Syndrome Following mRNA-1273 SARS-CoV-2 Vaccination.

Polymyalgia rheumatica (PMR) is an inflammatory rheumatic disease characterized by stiffness and aching mainly in the shoulders, neck and hip girdles. The underlying pathogenesis of PMR involves myeloid lineage activation with a high expression of pattern recognition receptors. In addition, vaccination against severe acute respiratory syndrome coronavirus 2 with mRNA-1273 functions as both an immunogen and intrinsic adjuvant. It leads to the activation of innate immunity, resulting in antibody production. We herein report the first case of PMR-like syndrome seven days after mRNA-1273 vaccination. Reassuringly, the symptoms, such as pain of the neck, shoulder girdle and pelvic girdle, as well as elevated inflammatory markers were resolved within a month without glucocorticoid or immunosuppressant administration.

Rheumatologic Manifestations of Post SARS-CoV-2 Infection: A Case Series.

BACKGROUND: It has been over a year since the first documented case of the COVID-19 virus was recorded. Since then, our understanding of this virus has continually evolved, however, its wide-ranging effects are still unfolding. Similar to previously studied viral infections, severe acute respiratory syndrome-associated coronavirus-2 (SARS-CoV-2) has been shown to lead to a degree of autoimmunity in patients who are recovering from its effects. Due to its effects on the innate immune system, such as the toll-like receptors and complement system, a varying degree of proinflammatory markers can become widespread in those who continue to recover from the virus. This case series offers a unique perspective on how COVID-19 has had dramatic effects on those already suffering from inflammatory rheumatic conditions, such as rheumatoid arthritis, systemic lupus erythematosus, or fibromyalgia. As the ever-lasting effects of COVID-19 are still unfolding, this case series is one of few to discuss the development and changes of patients with rheumatic conditions. This study hopes to encourage larger studies to be conducted on the effects of COVID- 19 on autoimmune conditions. CASE PRESENTATION: Seven patients were identified with new manifestations of rheumatic conditions, which included 3 cases of rheumatoid arthritis, 2 cases of polymyalgia rheumatica, 1 case of reactive arthritis, and 1 case of cutaneous lupus. Post-COVID syndrome was also diagnosed in 7 other patients. Patients with rheumatoid arthritis presented with symptoms 4-5 weeks after being diagnosed with COVID-19. Symptoms of polyarticular joint pain, swelling, and morning stiffness were reported in this group. These patients were treated with disease-modifying anti-rheumatic drugs and experienced an improvement in symptoms on follow-up. Two cases of polymyalgia rheumatica were identified in patients that were previously diagnosed with COVID-19 six weeks prior. One patient had no significant past medical history and the other patient had a history of rheumatoid arthritis, which was well controlled. These patients experienced weakness and tenderness in the proximal joints with elevated levels of ESR and CRP. They were treated with prednisone and showed improvement. Reactive arthritis was diagnosed in 1 patient who presented with swelling in both hands and wrists 2 days after being diagnosed with COVID-19. This patient began to experience symptoms of reactive arthritis 2 days after resolution of initial COVID-19 symptoms and this persisted for 3 months. The patient was managed with methylprednisolone injections and NSAIDs, which improved her symptoms. Post-COVID syndrome was identified in 7 patients. All patients were female and had a history of well-controlled fibromyalgia. Patients generally experienced fatigue, headaches, and memory fog, which had variable onset from a few days and up to 4 weeks after being diagnosed with COVID-19. One patient had a complete recovery of her symptoms at follow-up 3 months after the initial presentation. The other 6 patients continued to report symptoms of post-COVID syndrome at follow-up. Patients were managed with lifestyle modifications and their previous fibromyalgia treatment. CONCLUSION: While cases of COVID-19 continue to rise, complications of this disease are still being discovered. Those who initially recover from COVID-19 may experience new-onset rheumatic conditions, worsening of previously diagnosed rheumatic conditions, or post-COVID syndrome. As we continue to learn more about the effects of COVID-19, the awareness of these manifestations will play a key role in the appropriate management of these patients.

New-onset Polymyalgia Rheumatica Following the Administration of the Pfizer-BioNTech COVID-19 Vaccine.

We herein report the case of an 80-year-old Japanese woman who presented to our hospital with bilateral pain in the shoulders and hips lasting for a month since 2 days after the second dose of the BNT162b2 COVID-19 vaccine. Her physical findings, laboratory data, and ultrasonographic findings of bilateral biceps tenosynovitis and lateral subacromial bursitis were consistent with a diagnosis of polymyalgia rheumatica (PMR). She was successfully treated with oral prednisolone 15 mg/day. Although a causal relationship could not be definitively confirmed, PMR should be considered as a differential diagnosis in cases of persistent myalgia after administration of the BNT162b2 vaccine.
