ObjectivesTo better define the spectrum of new-onset post-COVID-19 and post-COVID-19 vaccine inflammatory rheumatic diseases (IRD) from a large multicentric observational study.MethodsConsecutive ...cases of IRD encountered during a 12-month period and satisfying one of the following inclusion criteria: (a) onset of the rheumatic manifestations within 4 weeks from SARS-CoV-2 infection or (b) onset of the rheumatic manifestations within 4 weeks from the administration of one of the COVID-19 vaccines ws recruited.ResultsThe final analysis cohort comprised 267 patients, of which 122 (45.2%) in the post-COVID-19 and 145 (54.8%) in the postvaccine cohort. Distribution of IRD categories differed between the two cohorts: the post-COVID-19 cohort had a higher percentage of patients classified as having inflammatory joint diseases (IJD, 52.5% vs 37.2%, p=0.013) while the post-vaccine cohort had a higher prevalence of patients classified as polymyalgia rheumatica (PMR, 33.1% vs 21.3%, p=0.032). No differences were detected in the percentage of patients diagnosed with connective tissue diseases (CTD 19.7% vs 20.7%, p=0.837) or vasculitis (6.6% vs 9.0%, p=0.467). Despite the short follow-up period, IJD and PMR patients’ response to first-line therapy was favourable, with both groups achieving a drop in baseline disease activity scores of ~30% and ~70% respectively.ConclusionOur article reports the largest cohort published to date of new-onset IRD following SARS-CoV-2 infection or COVID-19 vaccines. Although causality cannot be ascertained, the spectrum of possible clinical manifestations is broad and includes IJD, PMR, CTD and vasculitis.
Type II and type III cryoglobulinemic vasculitis (CV) are characterized by a deranged immune function due to concomitant chronic infections or rheumatic disorders. Conversely, type I CV is caused by ...plasma cell dyscrasia. Bortezomib is a proteasome inhibitor that is largely employed as a first-line treatment for multiple myeloma. The use of bortezomib in cases of monoclonal gammopathy of undetermined significance (MGUS)-related refractory type I CV has been reported in only four patients. In the current report, we discuss the efficacy of bortezomib treatment in a patient with type I CV, with a focus on the suitability and early application of this drug.
Anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines may trigger immune-mediated adverse events, including myocarditis. Evidence of vaccine safety in patients with rheumatic ...disorders and underlying autoimmune myocarditis is scarce. To address this issue, we studied 13 patients with systemic lupus erythematosus (SLE) and allied conditions with a history of myocarditis and receiving mRNA-based vaccines. Data about general and cardiac laboratory tests, treatment, and disease status were collected during routine consultations before and after the primary vaccination course and after each vaccine dose administration, while myocarditis symptoms were closely monitored. A significant increase in troponin levels from baseline was found after 13 (6–20) days from the first (p = 0.046) and 17 (4–29) days after the second dose (p = 0.013). Troponin levels progressively decreased within 3 (1–6) months in the absence of typical symptoms or signs of myocarditis. A significant increase in the constitutional domain of the British Isles Lupus Assessment Group (BILAG) index (p = 0.046) was observed in SLE patients. However, no patient needed any treatment change. mRNA-based anti-SARS-CoV-2 vaccines can apparently be safely administered to patients with SLE and lupus-like disorders with previous myocarditis despite potential subclinical and transient rises in cardiac damage markers.
•Mepolizumab (MPZ), an anti-IL5 monoclonal antibody, is a promising treatment for eosinophilic manifestations in eosinophilic granulomatosis with polyangiitis (EGPA).•Little is known on safety and ...efficacy of MPZ in EGPA in real-life.•This study provides evidence supporting routine use of MPZ use as a safe and effective treatment for refractory eosinophilic manifestations in patients with EGPA.•An apparent rise in minor infections during MPZ treatment warrants further studies.
Little is known about the efficacy and safety of the anti-interleukin 5 monoclonal antibody mepolizumab (MPZ) in patients with eosinophilic granulomatosis with polyangiitis (EGPA) in real-life. We thus evaluated disease activity, damage and disease-related complications in 14 patients with EGPA receiving MPZ for refractory disease for a median time of 16 months in comparison with up to five years before MPZ start. Asthma exacerbation rates, the Birmingham Vasculitis Activity Score and corticosteroid dosage decreased during MPZ (p < 0.001, p < 0.001 and p = 0.001, respectively). Five patients could discontinue prednisone. Infection rates were higher during MPZ (p < 10–6), but no rises in hospitalizations, asthma exacerbations or damage accrual were observed. Real-life data confirm the effectiveness of MPZ in refractory EGPA with active asthma. Higher infections rates are in line with other studies and might be due to relative overreporting secondary to increased visit frequency, although a pharmacological effect could not be ruled out.
18FFluorodeoxyglucose (18F-FDG) PET/CT is increasingly used to assess organ involvement and response to treatment in IgG4-related disease (IgG4-RD), but clear correlations between 18F-FDG uptake and ...disease activity have not been established yet. We aimed to correlate the intensity and distribution of 18F-FDG uptake with validated clinical, serological and immunological parameters of IgG4-RD activity.
Twenty patients with active IgG4-RD underwent a baseline 18F-FDG PET/CT. Ten patients repeated 18F-FDG PET/CT after immunosuppressive treatments. 18F-FDG tissue uptake was measured using the standardized uptake value corrected for the partial volume effect (PVC-SUV) and the total lesion glycolysis (TLG) with (TLGtot+ln) and without (TLGtot-ln) lymph nodes. Disease activity was assessed by means of clinical parameters IgG4-RD Responder Index (RI), serological (ESR and CRP) and immunological (serum IgG4 and circulating plasmablasts) biomarkers. The enhanced liver fibrosis score was exploited as a biomarker for fibroblast activation.
Thirteen (65%) patients had two or more organs affected by IgG4-RD. All patients had active IgG4-RD as defined by a median IgG4-RD RI value of 9 (range 6-15; normal < 3). Serum IgG4 and plasmablasts were elevated in 85% of patients. Circulating plasmablasts positively correlated with PVC-SUV (P = 0.027), inversely correlated with TLGtot-ln (P = 0.023) and did not correlate with TLGtot+ln (P > 0.05). No statistically significant correlation was found between PVC-SUV or TLG and IgG4-RD RI, ESR, CRP, serum IgG4 or enhanced liver fibrosis score (P > 0.05). Clinical response to immunosuppressive therapies was associated with a consensual reduction of circulating plasmablasts, PVC-SUV, TLGtot+ln and TLGtot-ln values (P < 0.05 for all comparisons).
18F-FDG uptake of IgG4-RD lesions reflects immunological perturbations of the B cell compartment rather than fibroblast activation and extracellular matrix deposition. Conventional biomarkers of disease activity, namely IgG4-RD RI, ESR, CRP and serum IgG4 levels, do not appear to correlate with the radiometabolic activity of IgG4-RD lesions. In light of our results PET/CT represents a reliable instrument for assessing IgG4-RD activity, although lymph-node uptake deserves careful interpretation.
Interleukin (IL)-1 inhibitors are largely employed in patients with Still's disease; in cases with refractory arthritis, IL-6 inhibitors have shown to be effective on articular inflammatory ...involvement. The aim of the present study is to assess any difference in the effectiveness of the IL-1β antagonist canakinumab prescribed as first-line biologic agent between the systemic and the chronic-articular Still's disease.
Data were drawn from the retrospective phase of the AutoInflammatory Disease Alliance (AIDA) international registry dedicated to Still's disease. Patients with Still's disease classified according to internationally accepted criteria (Yamaguchi criteria and/or Fautrel criteria) and treated with canakinumab as first-line biologic agent were enrolled.
A total of 26 patients (17 females, 9 males; 18 patients developing Still's disease after the age of 16 years) were enrolled; 16 (61.5%) patients suffered from the systemic pattern of the disease; 10 (38.5%) patients suffered from the chronic-articular type. No differences were observed between the systemic and the chronic-articular Still's disease in the frequency of complete response, of flares after the start of canakinumab (
= 0.701) and in the persistence in therapy (
= 0.62). No statistical differences were observed between the two groups after 3 months, 12 months and at the last assessment in the decrease of: the systemic activity score (
= 0.06,
= 0.17,
= 0.17, respectively); the disease activity score on 28 joints (
= 0.54,
= 0.77,
= 0.98, respectively); the glucocorticoid dosage (
= 0.15,
= 0.50, and
= 0.50, respectively); the use of concomitant disease modifying anti-rheumatic drugs (
= 0.10,
= 1.00, and
= 1.00, respectively). No statistically significant differences were observed in the decrease of erythrocyte sedimentation rate (
= 0.34), C reactive protein (
= 0.48), and serum ferritin levels (
= 0.34) after the start of canakinumab.
Canakinumab used for Still's disease has been effective in controlling both clinical and laboratory manifestations disregarding the type of disease course when used as first-line biotechnological agent. These excellent results might have been further enhanced by the early start of IL-1 inhibition.
Heart involvement (HInv) in systemic sclerosis (SSc) may relate to myocarditis and is associated with poor prognosis. Serum anti-heart (AHA) and anti-intercalated disk autoantibodies (AIDA) are organ ...and disease-specific markers of isolated autoimmune myocarditis. We assessed frequencies, clinical correlates, and prognostic impacts of AHA and AIDA in SSc.
The study included consecutive SSc patients (
= 116, aged 53 ± 13 years, 83.6% females, median disease duration 7 years) with clinically suspected heart involvement (symptoms, abnormal ECG, abnormal troponin I or natriuretic peptides, and abnormal echocardiography). All SSc patients underwent CMR. Serum AHA and AIDA were measured by indirect immunofluorescence in SSc and in control groups of non-inflammatory cardiac disease (NICD) (
= 160), ischemic heart failure (IHF) (
= 141), and normal blood donors (NBD) (
= 270). AHA and AIDA status in SSc was correlated with baseline clinical, diagnostic features, and outcome.
The frequency of AHA was higher in SSc (57/116, 49%,
< 0.00001) than in NICD (2/160, 1%), IHF (2/141, 1%), or NBD (7/270, 2.5%). The frequency of AIDA was higher (65/116, 56%,
< 0.00001) in SSc than in NICD (6/160, 3.75%), IHF (3/141, 2%), or NBD (1/270, 0.37%). AHAs were associated with interstitial lung disease (
= 0.04), history of chest pain (
= 0.026), abnormal troponin (
= 0.006), AIDA (
= 0.000), and current immunosuppression (
= 0.01). AHAs were associated with death (
= 0.02) and overall cardiac events during follow-up (
= 0.017).
The high frequencies of AHA and AIDA suggest a high burden of underdiagnosed autoimmune HInv in SSc. In keeping with the negative prognostic impact of HInv in SSc, AHAs were associated with dismal prognosis.
