Breakthrough SARS-CoV-2 infection and disease flares in patients with rheumatoid arthritis: result from COVAD e-survey study.

COVID-19 has been suggested as a possible trigger of disease flares in patients with rheumatoid arthritis (RA). However, factors associated with disease flares remain unknown. This study aimed to identify factors associated with breakthrough infection (BIs) and disease flares in patients with RA following COVID-19. We analysed data from RA patients who participated in the COVID-19 vaccination in autoimmune diseases (COVAD) study. Demographic data, patient-reported outcomes, comorbidities, pharmacologic treatment and details regarding disease flares were extracted from the COVAD database. Factors associated with disease flare-ups were determined by multivariate logistic regression analysis. The analysis comprised 1928 patients with RA who participated in the COVAD study. Younger age, Caucasian ethnicity, comorbidities with obstructive chronic pulmonary disease and asthma were associated with COVID-19 breakthrough infection. Moreover, younger age (odds ratio (OR): 0.98, 95% CI 0.96-0.99, p < 0.001), ethnicity other than Asian, past history of tuberculosis (OR: 3.80, 95% CI 1.12-12.94, p = 0.033), treatment with methotrexate (OR: 2.55, 95% CI: 1.56-4.17, p < 0.001), poor global physical health (OR: 1.07, 95% CI 1.00-1.15, p = 0.044) and mental health (OR: 0.91, 95% CI 0.87-0.95, p < 0.001) were independent factors associated disease flares in patients with RA. Our study highlights the impact of socio-demographic factors, clinical characteristics and mental health on disease flares in patients with RA. These insights may help determine relevant strategies to proactively manage RA patients at risk of flares.

The mode of delivery does not influence the occurrence of post-partum perianal disease flares in patients with inflammatory bowel disease

IntroductionPerianal disease occurs in up to 34% of inflammatory bowel disease (IBD) patients. An estimated 25% of women will become pregnant after the initial diagnosis, thus introducing the dilemma of whether mode of delivery affects perianal disease. The aim of our study was to analyze whether a cesarean section (C-section) or vaginal delivery influence perianal involvement. We hypothesized the delivery route would not alter post-partum perianal manifestations in the setting of previously healed perianal disease.MethodsAll consecutive eligible IBD female patients between 1997 and 2022 who delivered were included. Prior perianal involvement, perianal flare after delivery and delivery method were noted.ResultsWe identified 190 patients with IBD who had a total of 322 deliveries; 169 (52%) were vaginal and 153 (48%) were by C-section. Nineteen women (10%) experienced 21/322 (6%) post-partum perianal flares. Independent predictors were previous abdominal surgery for IBD (OR, 2.7; 95% CI, 1–7.2; p = 0.042), ileocolonic involvement (OR, 3.3; 95% CI, 1.1–9.4; p = 0.030), previous perianal disease (OR, 22; 95% CI, 7–69; p < 0.001), active perianal disease (OR, 96; 95% CI, 21–446; p < 0.001) and biologic (OR, 4.4; 95% CI,1.4–13.6; p < 0.011) or antibiotic (OR, 19.6; 95% CI, 7–54; p < 0.001) treatment. Negative association was found for vaginal delivery (OR, 0.19; 95% CI, 0.06–0.61; p < 0.005). Number of post-partum flares was higher in the C-section group [17 (11%) vs. 4 (2%), p = 0.002].ConclusionsDelivery by C-section section was not protective of ongoing perianal disease activity post-delivery, but should be recommended for women with active perianal involvement.

Reduction of Fecal Calprotectin Levels Induced by a Short Course of Escherichia Coli Nissle is Associated with a Lower Likelihood of Disease Flares in Patients with Ulcerative Colitis in Clinical Remission.

Fecal calprotectin (FC) is a biomarker of gut inflammation, and Escherichia coli Nissle 1917 (EcN) is a probiotic strain able to reduce gut inflammation and maintain disease remission in patients with inflammatory bowel disease (IBD). The aim is to assess the effects of EcN administration in patients with IBD in clinical remission and altered FC values. We prospectively included 82 patients with ulcerative colitis (UC) (n=49) and Crohn's disease (CD) (n=33) in clinical remission and with FC values above 250 mcg/g (T0) who were treated with EcN alone for 2 months. FC values were assessed at the end of EcN treatment (T1) and clinical disease activity at 3 months (T2). At T1 median FC values were significantly lower compared to T0 both in patients with CD (312 mcg/g vs 626 mcg/g, p<0.0001) and UC (100 mcg/g vs 584 mcg/g; p<0.0001). Patients with UC who experienced disease relapse at T2 had lesser reduction in median FC values at T1 (-229 mcg/g, vs -397 mcg/g, p=0.049), while in patients with CD we observed no statistically significant difference (-358 mcg/g, vs -427; p=0.568). In patients with UC, a reduction of at least 532 mcg/g in FC had an accuracy of 69.7% and a positive predictive value of 65.7% in predicting maintenance of remission. A short course of EcN was associated with a reduction of FC values in patients with IBD in clinical remission and baseline altered FC values, and in patients with UC this decrease was associated with maintenance of clinical remission.

Effect of SARS-CoV2 infection on disease flares in patients with systemic lupus erythematosus: a case-control study

Abstract Objectives To study the effect of SARS-CoV2 infection on flares of systemic lupus erythematosus (SLE). Methods Patients who fulfilled the ACR/SLICC criteria for SLE and had documented COVID-19 between February and November 2022 were identified retrospectively from our hospital COVID-19 registry. SLE controls who did not have SARS-CoV2 infection were randomly matched for age, sex and the time of infection in a 2:1 ratio with those infected. The primary outcome of interest was clinical flare of SLE within 90 days of COVID-19. The rate of SLE flares (mild/moderate or severe) was compared between SARS-CoV2-infected SLE patients and controls. Results 91 SLE patients with COVID-19 (age 48.6 ± 14.0 years; 95.6% women) and 182 SLE controls (age 48.7 ± 13.8 years; 95.6% women) were studied. Eleven of 91 (12.1%) SARS-CoV2-infected patients had serious manifestations. One (1.1%) patient died and 7(7.7%) developed severe complications. Within 90 days of SARS-CoV2 infection, 14(15.4%) patients developed mild/moderate clinical SLE flares and 2(2.2%) patients had severe SLE flares. The incidence of SLE flares in SARS-CoV2-infected patients was significantly higher than those without the infection (17.6% vs 5.5%; odds ratio 3.67[1.59–8.46]; p = 0.001). The changes in anti-dsDNA and complement levels, however, were not significantly different between the two groups. Among SARS-CoV2-infected SLE patients, those with clinical SLE flares had significantly lower C3 values (p = 0.004) before the infection than those without. Conclusion Clinical flares within 90 days were significantly more common in SLE patients infected with SARS-CoV2 than matched non-infected SLE controls.

Risk of flare in juvenile idiopathic arthritis: Is it related to the methotrexate treatment strategy or patient characteristics?

The study aimed to determine the factors that increase the risk of disease flare in patients with juvenile idiopathic arthritis who stopped methotrexate (MTX) monotherapy following inactive disease (ID). In the retrospective study, files of all juvenile idiopathic arthritis cases between April 1992 and June 2022 were examined. Patients who stopped MTX monotherapy following ID were evaluated. Patients with disease flare and persistent ID were compared. Juvenile idiopathic arthritis subgroup, age of symptom onset, autoantibodies, acute phase reactants, MTX method of use, and withdrawal strategy were recorded. Systemic juvenile idiopathic arthritis patients were excluded from the study due to different clinical symptoms, diagnosis, and treatment methods. Files of 1,036 patients were evaluated, and 107 patients (88 females, 19 males; mean age: 5.9±4.2 years; range, 0.8-16.5 years) were included in the study. The median age at symptom onset was 4.8 (interquartile range [IQR]: 2-7.6) years. In terms of juvenile idiopathic arthritis subgroups, 52 (48.6%) had oligoarticular juvenile idiopathic arthritis, 43 (40.2%) had polyarticular juvenile idiopathic arthritis, and 12 (11.2%) had juvenile psoriatic arthritis. The patients reached ID in nine (IQR: 4.8-17.7) months after starting MTX, and MTX treatment was discontinued after one (IQR: 0.7-1.3) year following ID. The disease flare developed in 59 (55%) of the cases. The ID continued in 48 (45%) patients. In multivariate analysis, the risk of flare was associated with younger symptom onset (odds ratio [OR]=2.2, p=0.006), antinuclear antibody positivity (OR=1.6, p=0.03), higher erythrocyte sedimentation rate (OR=1.01, p=0.04), and C-reactive protein (OR=1, p=0.02) at the MTX onset. No difference was observed between the two groups regarding MTX dose, route of administration, prior and concomitant treatments, time to reach ID, and time and method of MTX discontinuation. In this study, the risk of flare was associated with patient's characteristics, rather than the administration and discontinuation method of MTX.

Effect of tapered versus stable treatment with tumour necrosis factor inhibitors on disease flares in patients with rheumatoid arthritis in remission: a randomised, open label, non-inferiority trial

Urine and Plasma Complement Ba Levels During Disease Flares in Patients With Antineutrophil Cytoplasmic Autoantibody–Associated Vasculitis

Although the alternative complement pathway has been implicated in the pathogenesis of antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV), the specific nature of its involvement is unclear. This study measured levels of urine and plasma complement fragment Ba at multiple time points in a group of patients with AAV. The complement fragment Ba was measured by enzyme-linked immunosorbent assay in serial urine and plasma samples from 21 patients with AAV who developed a renal flare, 19 who developed a nonrenal flare, and 20 in long-term remission. Urine Ba levels were corrected for urine creatinine concentration. Changes in Ba levels were modeled using mixed linear-effect models. A logistic regression model was fit to predict a renal flare using Ba levels at the time of flare versus the nonrenal flare and long-term remission groups. Data from 60 patients with AAV were used for this analysis; 53% were male, 93% were White, and 74% had antiproteinase3-ANCA. Urine Ba levels increased at renal flare (P< 0.001) but remained stable during a nonrenal flare or long-term remission. Plasma Ba levels were stable over time in all groups. Urine Ba levels predicted a renal flare with an area under the curve of 0.76 (P< 0.001), with a cutoff of 12.53 ng/mg urine creatinine yielding a sensitivity of 76.2% and a specificity of 68.4%. Urine Ba levels, but not plasma Ba levels, are increased at the time of a renal flare in AAV, suggesting intrarenal complement activation and highlighting the potential use of this biomarker for surveillance of active renal vasculitis.

C-Reactive protein rise in rheumatology patients following COVID-19 vaccination.

The aim was to determine the proportion of patients with inflammatory arthritis who have a flare of their rheumatological disease within 4 weeks of receiving a coronavirus disease 2019 (COVID-19) vaccine, using CRP as a surrogate marker. A retrospective review was conducted of notes for patients with inflammatory arthritis within 30 days of their COVID-19 vaccine. An electronic database (DAWN) was used to identify all patients who were currently on a DMARD or biologic therapy. This was then correlated with vaccine data from the National Immunisation and Vaccination System (NIVS) and CRP within 30 days of their vaccination. From the DAWN database, 1620 adults were identified (mean age 61 years, 64% female). Three types of vaccinations were administered: AstraZeneca (AZ), BioNTech-Pfizer or Moderna. Vaccine uptake was 1542 of 1620 (95.2% for the first dose), 1550 of 1620 (95.7% for the second dose) and 1437 of 1620 (88.7% for the third dose). One hundred and ninety-two of 1542 patients (12.5%) had a CRP rise of >10 mg/l within 30 days of their vaccine, which was higher than the baseline flare rate of 8.6% (P = 0.0004). Patients with inflammatory arthritis and on DMARDs have a high uptake of COVID-19 vaccine (95%), which is greater than the national average. A CRP rise >10 mg/l within 30 days of vaccination was observed in ∼1 in 10 patients in our study population after all three doses. There might be a slight increase in disease flare in patients with inflammatory arthritis after COVID-19 vaccinations, and additional research is required to assess this association further.

Development of Autoantibodies Following BNT162b2 mRNA COVID-19 Vaccination and Their Association with Disease Flares in Adult Patients with Autoimmune Inflammatory Rheumatic Diseases (AIIRD) and the General Population: Results of 1-Year Prospective Follow-Up Study.

Development of autoantibodies following BNT162b2 mRNA COVID-19 vaccination and their association with disease flares in adult patients with autoimmune inflammatory rheumatic diseases (AIIRD) and the general population: results of 1-year prospective follow-up study. We conducted a prospective study aimed at investigating the incidence of appearance of autoantibodies (antinuclear, antiphospholipid, and rheumatoid factor) in the sera of 463 adult patients with AIIRD compared to 55 controls from the general population prior to, and following the second and third vaccine doses, and at 1-year of follow-up. Pre- and post-vaccination disease activity indices and the association of autoantibodies with rheumatic disease flares and new onset AIIRD were examined. Autoantibody development of any type in AIIRD patients vs. the controls was 4.0% (vs. 6.7%, p = 0.423) following two vaccine doses and 7.6% (vs. 0%, p = 0.152) after three doses. There was no significant difference in sex, age, or disease-type among individuals with and without autoantibody development, regardless of the immunosuppressant use. More patients developed autoantibodies following the third than the second vaccine dose (p = 0.004). Disease flares occurred in 5.8% and 7.2% of AIIRD patients following second and third vaccine doses, respectively, with autoantibody production increasing the risk of flares following the second (p = 0.002) and third (p = 0.004) vaccine doses. BNT162b2 vaccination resulted in the development of autoantibodies in a minority of AIIRD patients and controls. Autoantibody development was associated with disease flares in patients, but no new-onset autoimmunity was observed.

Hesitancy for SARS-CoV-2 vaccines and post-vaccination flares in patients with systemic lupus erythematosus

ObjectivesTo study the rate of SARS-CoV-2 vaccination and post-vaccination disease flares in patients with systemic lupus erythematosus (SLE). MethodsPatients who fulfilled ≥ 4 of the ACR criteria for SLE were identified and their SARS-CoV-2 vaccination status was traced. Flares of SLE at 6-week post-vaccination were reviewed retrospectively. Clinical characteristics of patients with and without vaccination, and those who did or did not experience post-vaccination flares were compared by statistical analyses. Results914 adult patients with SLE were studied (92.5 % women, age 48.6 ± 14.0 years; SLE duration 14.5 ± 8.6 years). Two doses of the SARS-Cov-2 vaccines (61.5 % BioNTech; 38.5 % CoronaVac) were received by 449 (49.1 %) patients. The vaccination rate in SLE was significantly lower than that of the adult general population (77.8 %; p < 0.001) at the time of data analysis. Patients who were hesitant for vaccination were more likely to be hypertensive, have a history of neuromuscular manifestations, and a significantly higher organ damage score (1.10 ± 1.45 vs 0.74 ± 1.15; p < 0.001). However, none of these factors were significantly associated with vaccine hesitancy on multivariate analysis. Among 449 vaccinated patients, 37(8.2 %) experienced SLE flares: mild/moderate in 34; severe in 3. In an equal number of unvaccinated SLE controls randomly matched for the post-vaccination observation period, 28(6.2 %) had SLE flares: mild/moderate in 17; severe in 11 (odds ratio [OR] for flare in vaccinated patients 1.40[0.81–2.43]; p = 0.23, adjusted for age, sex, active serology, SLE duration and prednisolone use). In vaccinated patients, logistic regression revealed that active lupus serology before vaccination (OR 2.63[1.05–6.62]; p = 0.04) and a history of arthritis (OR 2.71[1.05–7.00]; p = 0.04) or discoid skin lesion (OR 4.73[1.90–11.8]; p = 0.001) were associated with SLE flares following vaccination, adjusted for confounders. ConclusionHesitancy for COVID-19 vaccination is common in SLE patients. Vaccination against SARS-CoV-2 is not significantly associated with increased SLE flares. Patients with active SLE serology or a history of arthritis/discoid lesion are more likely to flare after vaccination.

Stress, mindfulness, and systemic lupus erythematosus: An overview and directions for future research.

Although the pathogenesis of autoimmunity is not fully understood, it is thought to involve genetic, hormonal, immunologic, and environmental factors. Stress has been evaluated as a potential trigger for autoimmunity and disease flares in patients with systemic lupus erythematosus (SLE). The physiologic changes that occur with stress involve numerous catecholamines, hormones, and cytokines that communicate intricately with the immune system. There is some evidence that these systems may be dysregulated in patients with autoimmune disease. Mindfulness-based techniques are practices aimed at mitigating stress response and have been shown to improve quality of life in general population. This review will discuss pathophysiology of chronic stress as it relates to SLE, evidence behind mindfulness-based practices in these patients, and directions for future research.

Disease flare in patients with dermatomyositis following COVID-19 vaccination

To the Editor: Since December 2020, COVID-19 vaccinations have effectively prevented severe SARS-CoV-2 disease. The American College of Rheumatology recommends that individuals with systemic autoimmune rheumatic diseases receive COVID-19 vaccination given increased severe illness risk.1 Despite the benefits of vaccination, fear of disease flare postvaccination continued to drive vaccine hesitancy.2

Impact of isotretinoin on inflammatory bowel disease flare in patients with preexisting inflammatory bowel disease diagnosis: A cross-sectional study

To the Editor: Early studies of isotretinoin for use in severe acne suggested that the drug may serve as a trigger for new-onset inflammatory bowel disease (IBD).1 Although more recent studies have suggested no such causal relationship, little is known about the medication’s effect on patients with a preexisting IBD diagnosis.2 This cross-sectional study evaluates the risk of IBD flare in patients with IBD treated with isotretinoin for acne.

Mepolizumab Reduces Hypereosinophilic Syndrome Flares Irrespective of Blood Eosinophil Count and Interleukin-5

Mepolizumab, an anti-interleukin-5 (IL-5) antibody, reduces disease flares in patients with hypereosinophilic syndrome (HES). Factors predicting treatment response are unknown. To assess mepolizumab efficacy by baseline blood eosinophil count (BEC) and serum IL-5 level in patients with HES. This post hoc analysis used data from the phase III study assessing mepolizumab in patients with HES (NCT02836496). Patients 12 years old or older, with HES for 6 or more months, 2 or more flares in the previous year, and BEC ≥1,000 cells/μL at screening were randomized (1:1) to 4-weekly subcutaneous mepolizumab (300 mg) or placebo, plus baseline HES therapy, for 32 weeks. The proportion of patients experiencing 1 or more flares (wk 32), annualized flare rate, and proportion of patients with change from baseline in Brief Fatigue Inventory (BFI) item 3 (wk 32), were analyzed by baseline BEC (<1500/≥1500 to <2500/≥2500 cells/μL). Flare outcomes were assessed by baseline serum IL-5 (<7.81/≥7.81 pg/mL). Across baseline BEC subgroups, mepolizumab reduced the proportion of patients experiencing 1 or more flares by 63% to 90% and flare rate by 58% to 84% (treatment-by-eosinophil interaction P= .76 and P= .90, respectively); patients had improved BFI item 3 score with mepolizumab versus placebo (cells/μL: <1,500: 54% vs 37%; ≥1,500 to <2,500: 47% vs 31%; ≥2,500: 61% vs 0%; treatment-by-eosinophil interaction P= .42). Most patients had undetectable baseline serum IL-5 levels; among these, mepolizumab versus placebo reduced the proportion of patients with 1 or more flares (77%) and flare rate (67%). Mepolizumab was efficacious in the patients with HES studied, irrespective of baseline BEC. Undetectable IL-5 levels should not preclude mepolizumab treatment.

Ultrasound-detected tenosynovitis as a risk factor for flares in rheumatoid arthritis patients in clinical remission.

Our objective was to investigate the value of ultrasound (US) detected synovitis and tenosynovitis as risk factors for short term flare in rheumatoid arthritis (RA) patients in clinical remission. Consecutive RA patients in clinical remission (DAS28 ERS < 2.6) for at least 3months underwent Power Doppler ultrasound (PDUS) examination of 1st to 6th extensor compartments at the wrist, 2nd to 5th finger flexor, posterior tibial tendon, and peroneal tendons. To assess synovitis, carpal joints, 1st to 5th metacarpophalangeal (MCP) joints, and 2nd to 5th interphalangeal proximal (IPP) joints were bilaterally examined. Synovitis and tenosynovitis were defined according to OMERACT. Patients were followed for 1year. Disease flare was defined as an increase in disease activity generating the need for a change in therapy by the attending rheumatologist. Ninety patients were included. After 1year of follow-up, 26 patients (29%) experienced a flare. At baseline 39%, 23% and 8% had US-detected synovitis, tenosynovitis or both, respectively. In the 1-year period after the baseline US examination, US-detected tenosynovitis (RR: 4.9; 95% CI: 2.2-10.8) was associated with an increased risk of exacerbation. This association was not shown with US-detected synovitis (RR: 1.3; 95% CI: 0.76-2.2). In the multivariate analysis, only subclinical tenosynovitis (OR: 9.8; 95% CI: 2.5-39.1; p = 0.001) and baseline DAS28 (OR: 5.7; 95% CI: 1.1-31.6; p = 0.047) were significantly associated with an increased risk of having a flare. In our study, subclinical tenosynovitis was associated with disease flare in patients with RA in clinical remission. • Synovitis and tenosynovitis are risk factors for short term flare in RA patients in clinical remission. • Subclinical tenosynovitis, but not synovitis, was associated with disease flare in patients with unstable remission. • Ultrasound-detected tenosynovitis could be useful to predict relapses in RA patients in clinical remission.
