Systematic screening for multimorbidities in patients with inflammatory rheumatic diseases enhanced preventive medication use and reduced hospitalisations: an exposed-non-exposed study.

RATIONAL: Studies are needed to determine if multimorbidity screening and management reduce the rate of multimorbidity accumulation in patients with chronic inflammatory rheumatic diseases (IRD). OBJECTIVES: This study evaluates the impact of systematic screening programme on patient care and hospitalisation rates. METHODS: Patients with IRD who participated in the screening programme (exposed patients) were identified within the French national health database and matched with controls. Two sets of analysis were performed: one with multivariate analysis and a second using a propensity score matching to ensure comparability between exposed patients and controls. The primary endpoint (PE) was a composite score assessing the dispensation of multimorbidity-preventing drugs, including vaccines, lipid-lowering agents, antiosteoporotic medications and antiplatelet drugs, during the year following the index date. RESULTS: The first analysis included 286 exposed patients and 858 controls, demonstrating a higher rate of meeting the PE in exposed patients (adjusted OR=1.6 (1.2-2.2), p<0.01). Propensity score matching resulted in 281 exposed patients and 281 controls. Exposed patients exhibited a significantly higher rate of meeting the PE compared with controls (54.8% vs 44.5%; OR=1.5; p=0.015), with increased utilisation of vaccines, cholesterol-lowering drugs and antiosteoporotic medications. Furthermore, emergency admission and hospitalisations for fracture, cardiovascular events or infection were significantly less frequent in the exposed group (7.1% vs 15.3%; OR=0.42, p<0.01), with a reduction in severe infections (0.7% vs 3.9%; p=0.03). CONCLUSION: Systematic multimorbidity screening in patients with IRD boosted preventive medication use and reduced hospital admissions, justifying time and resource allocation for screening.

Comparative early effectiveness across 14 PsA drugs and 5 classes of PsA treatment: 3-month results from the PRO-SPIRIT study.

BACKGROUND: The psoriatic arthritis (PsA) Observational Study of Persistence of Treatment (PRO-SPIRIT) assesses effectiveness and persistence of real-world PsA treatments. Ixekizumab (IXE) is an interleukin (IL)-17A inhibitor (i) (IL-17Ai), approved for the treatment of adult PsA. METHODS: The aim of this predefined interim analysis was to report baseline characteristics along with early (3-month) descriptive and comparative real-world effectiveness in patients with PsA prescribed with advanced treatment including IL-17Ai; IXE or secukinumab (SEC), IL-12/23i, IL-23i, tumour necrosis factor (TNFi) or Janus kinase (JAKi). RESULTS: 1192 patients across 6 countries were analysed. At baseline, patients receiving IXE had longer disease duration and higher previous biological/targeted-synthetic disease-modifying antirheumatic drugs experience than patients starting TNFi and SEC 150, and less concomitant conventional-synthetic DMARD use than TNFi and JAKi. Comparative analyses at 3 months showed that: (a) versus TNFi, IXE exhibited similar improvement in clinical Disease Activity in PsA (cDAPSA) but significantly greater improvement in body surface area affected by psoriasis (BSA) and global assessments (physician GA, patient GA (PatGA)); (b) versus IL-12/23i and IL-23i (pooled), IXE showed significantly greater improvement in cDAPSA and PatGA; (c) IXE was as fast as JAKi in improving joint disease activity. Ad hoc analysis indicated that more patients with active psoriasis (BSA ≥3%) achieved minimal disease activity with IXE than JAKi or IL-12/23i. The responses to SEC varied by dosage. CONCLUSIONS: This study confirms the rapid 3-month effectiveness of IXE on joint disease activity-as fast as TNFi and JAKi (cDAPSA), and exceeding IL-12/23i and IL-23i-along with clear benefits to skin.

Association between humoral serological markers levels and risk of SARS-CoV-2 infection after the primary COVID-19 vaccine course among ANRS0001S COV-POPART cohort participants.

BACKGROUND: We assessed the prognostic value of serological humoral markers measured one month after the last dose of the primary COVID-19 vaccine course for predicting the risk of severe acute respiratory syndrome coronavirus 2 SARS-CoV-2 infection over the following six months in specific populations. METHODS: ANRS0001SCOV-POPART is a French nationwide multicenter prospective observational cohort study assessing the immune response to Covid-19 vaccines routinely administered to 11 subgroups of patients with chronic disease and a control group. Participants from the ANRS0001S COV-POPART were included if they received at least two doses of Covid-19 vaccine for the primary vaccine course, had measurements of anti-Spike, anti-receptor binding domain (RBD) IgG-specific or neutralizing antibodies one month after the end of the primary vaccine course, without being infected by SARS-CoV-2 before the measurement. SARS-CoV-2 infections defined by a positive PCR/antigenic test or seroconversion to detectable anti nucleocapsid antibodies were evaluated until the first COVID-19 booster injection. Cox proportional hazards models taking into account interval-censored data were implemented to estimate the association between each antibody level and the risk of SARS-CoV-2 infection. Predictive performances were evaluated by the area under the receiving operating characteristic curve (AUROC). RESULTS: Two thousand five hundred seventy adults from a specific population and 1,123 from the control group were included. The cumulative probabilities of SARS-CoV-2 infections at five months after serological measurement were 6.0% 95% confidence interval: [5.0; 7.9] and 10.1% 95% confidence interval: [8.3; 11.9], respectively. Higher levels of anti-Spike IgG antibody were associated with a lower risk of SARS-CoV-2 infections in the control group, but not in the specific populations. Among the specific populations, AUROC were 74.5%, 74.9%, and 72.4% for anti-Spike IgG, anti-RBD IgG, and neutralizing antibodies, respectively. AUROC were superior in the specific populations, 82.0%, 81.2%, and 81.4% for anti-Spike IgG, anti-RBD IgG, and neutralizing antibodies, respectively. CONCLUSIONS: Vaccine-induced antibody response after the primary course of Covid-19 infection only moderately discriminated between participants developing a SARS-CoV-2 infection during the Omicron wave. TRIAL REGISTRATION: NCT04824651 (first posted: 2021-04-01).

Persistence of power Doppler ultrasonography-detected synovitis over 1 year of follow-up predicts poor prognosis in rheumatoid arthritis in clinical remission: the SONORE prospective longitudinal study.

OBJECTIVES: (1) To assess the progression of ultrasonography-detected synovitis in a cohort of patients with rheumatoid arthritis (RA) in remission during 1 year of follow-up (2) to evaluate the ability of consecutive examinations of ultrasonography to predict relapse (R) or radiographic progression (RP) at 1 year. METHODS: Patients with RA (2010 American College of Rheumatology-European Alliance of Associations for Rheumatology criteria) in clinical remission (Disease Activity Score in 28 joints (DAS28)<2.6 without clinically active synovitis) were included. An independent investigator performed ultrasonography every 3 months for 1 year. Ultrasonography-detected synovitis was defined as power Doppler-positive ultrasonography synovitis (PDUS) grade ≥1 in at least one joint. PDUS at ≥2 consecutive visits during the follow-up defined persistent PDUS. An increase of ≥1 point in the modified total Sharp score defined RP. An increase in DAS28-C-reactive protein (CRP)>0.6 or DAS28-CRP>3.2 and any modification of disease-modifying anti-rheumatic drugs or glucocorticoids defined relapse. Univariate and multivariate Cox regression analyses were used to evaluate factors associated with R/RP at 1 year. RESULTS: PDUS was detected in 75 (65.2%), 66, 60, 46 and 29 of the 115 patients with RA at baseline and at months 3, 6, 9 and 12, respectively. 58 (50.4%) patients exhibited persistent PDUS. After 1 year, 22/85 (25.9%) experienced relapse and 12 (14.1%) showed RP. On multivariate analysis, factors predicting R/RP at 1 year were persistent PDUS (HR=2.98, p=0.014) and an increase in DAS28-CRP level at the visit before relapse (HR=4.36, p=0.004). CONCLUSION: Persistent PDUS during follow-up, rather than at baseline, predicted worse outcome at 1 year and requires careful monitoring.

Recommendations of the French Society of Rheumatology for the management in current practice of patients with polymyalgia rheumatica.

OBJECTIVE: To develop recommendations for the routine management of patients with polymyalgia rheumatica (PMR). METHODS: Following standard procedures, a systematic review of the literature by five supervised junior rheumatologists, based on the questions selected by the steering committee (5 senior rheumatologists), was used as the basis for working meetings, followed by a one-day plenary meeting with the working group (15 members), leading to the development of the wording and determination of the strength of the recommendations and the level of agreement of the experts. RESULTS: Five general principles and 19 recommendations were drawn up. Three recommendations relate to diagnosis and the use of imaging, and five to the assessment of the disease, its activity and comorbidities. Non-pharmacological therapies are the subject of one recommendation. Three recommendations concern initial treatment based on general corticosteroid therapy, five concern the reduction of corticosteroid therapy and follow-up, and two concern corticosteroid dependence and steroid-sparing treatments (anti-IL-6). CONCLUSION: These recommendations take account of current data on PMR, with the aim of reducing exposure to corticosteroid therapy and its side effects in a fragile population. They are intended to be practical, to help practitioners in the day-to-day management of patients with PMR.

Identification of distinct subgroups of Sjögren's disease by cluster analysis based on clinical and biological manifestations: data from the cross-sectional Paris-Saclay and the prospective ASSESS cohorts.

BACKGROUND: Sjögren's disease is a heterogenous autoimmune disease with a wide range of symptoms-including dryness, fatigue, and pain-in addition to systemic manifestations and an increased risk of lymphoma. We aimed to identify distinct subgroups of the disease, using cluster analysis based on subjective symptoms and clinical and biological manifestations, and to compare the prognoses of patients in these subgroups. METHODS: This study included patients with Sjögren's disease from two independent cohorts in France: the cross-sectional Paris-Saclay cohort and the prospective Assessment of Systemic Signs and Evolution of Sjögren's Syndrome (ASSESS) cohort. We first used an unsupervised multiple correspondence analysis to identify clusters within the Paris-Saclay cohort using 26 variables comprising patient-reported symptoms and clinical and biological manifestations. Next, we validated these clusters using patients from the ASSESS cohort. Changes in disease activity (measured by the European Alliance of Associations for Rheumatology [EULAR] Sjögren's Syndrome Disease Activity Index [ESSDAI]), patient-acceptable symptom state (measured by the EULAR Sjögren's Syndrome Patient Reported Index [ESSPRI]), and lymphoma incidence during follow-up were compared between clusters. Finally, we compared our clusters with the symptom-based subgroups previously described by Tarn and colleagues. FINDINGS: 534 patients from the Paris-Saclay cohort (502 [94%] women, 32 [6%] men, median age 54 years [IQR 43-64]), recruited between 1999 and 2022, and 395 patients from the ASSESS cohort (370 [94%] women, 25 [6%] men, median age 53 years [43-63]), recruited between 2006 and 2009, were included in this study. In both cohorts, hierarchical cluster analysis revealed three distinct subgroups of patients: those with B-cell active disease and low symptom burden (BALS), those with high systemic disease activity (HSA), and those with low systemic disease activity and high symptom burden (LSAHS). During follow-up in the ASSESS cohort, disease activity and symptom states worsened for patients in the BALS cluster (67 [36%] of 186 patients with ESSPRI score <5 at month 60 vs 92 [49%] of 186 at inclusion; p<0·0001). Lymphomas occurred in patients in the BALS cluster (five [3%] of 186 patients; diagnosed a median of 70 months [IQR 42-104] after inclusion) and the HSA cluster (six [4%] of 158 patients; diagnosed 23 months [13-83] after inclusion). All patients from the Paris-Saclay cohort with a history of lymphoma were in the BALS and HSA clusters. This unsupervised clustering classification based on symptoms and clinical and biological manifestations did not correlate with a previous classification based on symptoms only. INTERPRETATION: On the basis of symptoms and clinical and biological manifestations, we identified three distinct subgroups of patients with Sjögren's disease with different prognoses. Our results suggest that these subgroups represent different heterogeneous pathophysiological disease mechanisms, stages of disease, or both. These findings could be of interest when stratifying patients in future therapeutic trials.

Risk of severe infection associated with immunoglobulin deficiency under rituximab therapy in immune-mediated inflammatory disease.

OBJECTIVES: We evaluated the risk of severe infection in patients with immune-mediated inflammatory disease (IMID) treated with RTX and with Ig deficiency. METHODS: This was an observational, retrospective single-centre study of patients undergoing treatment with at least one rituximab (RTX) infusion for an IMID until 31 May 2020. Patients were followed up for at least 12 months after the last infusion or until severe infection or death. Ig deficiency was classified as prevalent (before RTX) or acquired (normal Ig assay results before RTX but Ig deficiency during a follow-up). RESULTS: Of 311 patients, 10.6% had prevalent and 19.6% acquired Ig deficiency. Prevalent Ig deficiency was related to concomitant treatment with glucocorticoids (GCs), in particular with a high daily dose at baseline; and acquired Ig deficiency to cumulative dose of RTX, mean Disease Activity Score in 28 joints (DAS28), immunosuppressor or GCs therapy at baseline, diabetes mellitus and obesity. Overall, 14.5% of patients had a severe infection during follow-up, which was numerically but not statistically more frequent in patients with prevalent Ig deficiency than normal Ig level. On multivariate analysis, risk of severe infection was associated with chronic pulmonary disease, GCs dose and mean DAS28-C reactive protein. In a time-dependent analysis, risk of severe infection was not associated with Ig deficiency, either acquired or prevalent (adjusted HR 1.04 (95% CI 0.5 to 2.3), p=0.92). CONCLUSION: Risk of severe infection was not associated with RTX-induced Ig deficiency in patients with an IMID. RTX management should be discussed according to an individual assessment of the infectious risk, especially in patients with GC therapy or chronic lung disease.

Towards the Lowest Efficacious Dose: Results From a Multicenter Noninferiority Randomized Open-Label Controlled Trial Assessing Tocilizumab or Abatacept Injection Spacing in Rheumatoid Arthritis in Remission.

OBJECTIVE: We assess the clinical and structural impact at two years of progressively spacing tocilizumab (TCZ) or abatacept (ABA) injections versus maintenance at full dose in patients with rheumatoid arthritis in sustained remission. METHODS: This multicenter open-label noninferiority (NI) randomized clinical trial included patients with established rheumatoid arthritis in sustained remission receiving ABA or TCZ at a stable dose. Patients were randomized to treatment maintenance (M) at full dose (M-arm) or progressive injection spacing (S) driven by the Disease Activity Score in 28 joints every 3 months up to biologics discontinuation (S-arm). The primary end point was the evolution of disease activity according to the Disease Activity Score in 44 joints during the 2-year follow-up analyzed per protocol with a linear mixed-effects model, evaluated by an NI test based on the one-sided 95% confidence interval (95% CI) of the slope difference (NI margin 0.25). Other end points were flare incidence and structural damage progression. RESULTS: Overall, 202 of the 233 patients included were considered for per protocol analysis (90 in S-arm and 112 in M-arm). At the end of follow-up, 16.2% of the patients in the S-arm could discontinue their biologic disease-modifying antirheumatic drug, 46.9% tapered the dose and 36.9% returned to a full dose. NI was not demonstrated for the primary outcome, with a slope difference of 0.10 (95% CI 0.10-0.31) between the two arms. NI was not demonstrated for flare incidence (difference 42.6%, 95% CI 30.0-55.1) or rate of structural damage progression at two years (difference 13.9%, 95% CI -6.7 to 34.4). CONCLUSION: The Towards the Lowest Efficacious Dose trial failed to demonstrate NI for the proposed ABA or TCZ tapering strategy.

Chronological interplay, clinical features, and treatments among patients with cancer and primary Sjögren's syndrome.

OBJECTIVE: While the incidence and type of blood malignancies are well documented amid primary Sjögren's syndrome patients (pSS), data focusing on solid neoplasms are more conflicting. We aimed to describe clinical, pathological, and immunological characteristics of pSS patients with cancers, along with the chronological interplay between the two conditions. METHODS: Outcomes concerning both pSS and cancer were retrospectively collected from Montpellier University Hospital (tertiary center) between 2019 and 2020. pSS characteristics were compared to a control group of pSS patients without cancer. RESULTS: A total of 165 patients with pSS were included: 55 patients with cancer (52 female, mean age 58.4 ± 10.4 years at pSS diagnosis; mean follow-up 10.5 ± 10.1 years, 12 patients had multiple cancers) and 110 controls without cancer. Characteristics of pSS patients with cancers were different from controls mostly for lymphoma prognosis factors. Among the 70 cancers, we recorded 55 solid neoplasms (whom 27 breast cancers and 8 lung cancers, and 82% of adenocarcinomas), with no evidence of disease at the end of follow-up in 85% of them. Among the 15 recorded blood malignancies, ten were lymphomas with an excellent prognosis. Regarding chronological interplay between cancer and pSS, most cancers (43%) were diagnosed close (± 5 years) to pSS diagnosis. Breast cancers were diagnosed before or close to pSS diagnosis (mean delay - 1.8 ± 13.0 years), at an early stage, with only two relapses (no cancer-related death), while lung cancers were diagnosed late after. CONCLUSIONS: The tight chronological interplay between breast cancer and pSS and the intriguing pathological and immunological pattern of pSS in these patients suggest a hypothesis of immune control of cancer.

2022 EULAR recommendations for screening and prophylaxis of chronic and opportunistic infections in adults with autoimmune inflammatory rheumatic diseases

To develop EULAR recommendations for screening and prophylaxis of chronic and opportunistic infections in patients with autoimmune inflammatory rheumatic diseases (AIIRD). An international Task Force (TF) (22 members/15 countries) formulated recommendations, supported by systematic literature review findings. Level of evidence and grade of recommendation were assigned for each recommendation. Level of agreement was provided anonymously by each TF member. Four overarching principles (OAP) and eight recommendations were developed. The OAPs highlight the need for infections to be discussed with patients and with other medical specialties, in accordance with national regulations. In addition to biologic/ targeted synthetic disease-modifying antirheumatic drugs (DMARDs) for which screening for latent tuberculosis (TB) should be performed, screening could be considered also before conventional synthetic DMARDs, glucocorticoids and immunosuppressants. Interferon gamma release assay should be preferred over tuberculin skin test, where available. Hepatitis B (HBV) antiviral treatment should be guided by HBV status defined prior to starting antirheumatic drugs. All patients positive for hepatitis-C-RNA should be referred for antiviral treatment. Also, patients who are non-immune to varicella zoster virus should be informed about the availability of postexposure prophylaxis should they have contact with this pathogen. Prophylaxis against Pneumocystis jirovecii seems to be beneficial in patients treated with daily doses >15­30mg of prednisolone or equivalent for >2­4 weeks. These recommendations provide guidance on the screening and prevention of chronic and opportunistic infections. Their adoption in clinical practice is recommended to standardise and optimise care to reduce the burden of opportunistic infections in people living with AIIRD.

Can efficacy and safety data from clinical trials of rituximab in RA be extrapolated? Insights from 1984 patients from the AIR-PR Registry.

OBJECTIVES: To investigate whether the efficacy and safety data from drug-registration trials can be extrapolated to real-life RA patients receiving RTX. METHODS: The AIR-PR registry is a French multicentre, prospective cohort of RA patients treated with RTX in a real-life setting. We compared treatment responses at 12 months and serious AEs between eligible and non-eligible patients, by retrieving the eligibility criteria of the three rituximab-registration trials. We determined critical eligibility criteria and modelled the benefit-risk ratio according to the number of fulfilled critical eligibility criteria. RESULTS: Among 1984 RA patients, only 9-12% fulfilled all eligibility criteria. Non-eligible patients had less EULAR response at 12 months (40.3% vs 46.9%, p= 0.044). Critical inclusion criteria included SJC ≥ 4, TJC ≥ 4, CRP ≥ 15 mg/l, and RF positivity. Critical exclusion criteria were age >80 years, RA-associated systemic diseases, ACR functional class IV, other DMARD than methotrexate, and prednisone > 10 mg/day. Only 20.8% fulfilled those critical eligibility criteria. During the first year, serious AEs occurred for 182 (9.2%) patients, (70.3% serious infections) and patients with ≥1 critical exclusion criterion were at higher risk (HR 3.03; 95%CI 2.25-4.06; for ≥ 3 criteria vs 0). The incremental risk-benefit ratio decreased with the number of unmet critical inclusion criteria and of fulfilled exclusion criteria. CONCLUSION: Few real-life RA patients were eligible for the drug-registration trials. Non-eligible patients had lower chance of response, and higher risk of serious AEs. Efficacy and safety data obtained from those trials may not be generalizable to RA patients receiving RTX in real-world clinical practice.

Long-range fiber-optic earthquake sensing by active phase noise cancellation.

We present a long-range fiber-optic environmental deformation sensor based on active phase noise cancellation (PNC) in metrological frequency dissemination. PNC sensing exploits recordings of a compensation frequency that is commonly discarded. Without the need for dedicated measurement devices, it operates synchronously with metrological services, suggesting that existing phase-stabilized metrological networks can be co-used effortlessly as environmental sensors. The compatibility of PNC sensing with inline amplification enables the interrogation of cables with lengths beyond 1000 km, making it a potential contributor to earthquake detection and early warning in the oceans. Using spectral-element wavefield simulations that accurately account for complex cable geometry, we compare observed and computed recordings of the compensation frequency for a magnitude 3.9 earthquake in south-eastern France and a 123 km fiber link between Bern and Basel, Switzerland. The match in both phase and amplitude indicates that PNC sensing can be used quantitatively, for example, in earthquake detection and characterization.

French national diagnostic and care protocol for Sjögren's disease.

Sjögren's disease (SD), also known as Sjögren's syndrome (SS) or Gougerot-Sjögren's syndrome in France, is a rare systemic autoimmune disease in its primary form and is characterised by tropism for the exocrine glandular epithelia, particularly the salivary and lacrimal glands. The lymphocytic infiltration of these epithelia will clinically translate into a dry syndrome which, associated with fatigue and pain, constitutes the symptom triad of the disease. In about one third of patients, SD is associated with systemic complications that can affect the joints, skin, lungs, kidneys, central or peripheral nervous system, and lymphoid organs with an increased risk of B-cell lymphoma. SD affects women more frequently than men (9/1). The peak frequency is around the age of 50. However, the disease can occur at any age, with paediatric forms occurring even though they remain rare. SD can occur alone or in association with other systemic autoimmune diseases. In its isolated or primary form, the prevalence of SD is estimated to be between 1 per 1000 and 1 per 10,000 inhabitants. The most recent classification criteria were developed in 2016 by EULAR and ACR. The course and prognosis of the disease are highly variable and depend on the presence of systemic involvement and the severity of the dryness of the eyes and mouth. The current approach is therefore to identify at an early stage those patients most at risk of systemic complications or lymphoma, who require close follow-up. On the other hand, regular monitoring of the ophthalmological damage and of the dental status should be ensured to reduce the consequences.

Infection prevention and vaccination in the rheumatic diseases.

Patients with chronic inflammatory rheumatisms (CIR) have a higher risk of infections compared to healthy subjects. Viral and bacterial pneumonia are the most frequent infections observed in CIR with targeted disease modifying anti-rheumatic drugs (DMARDs). Moreover, drugs used to treat CIR (especially biologic and synthetic targeted DMARDs) increase the risk of infection and expose CIR patients to opportunistic infections such as tuberculosis reactivation. To limit the risk of infection, the risk-benefit ratio should be evaluated for each patient based on their characteristics and comorbidities. To prevent infections, an initial pre-treatment work-up must be performed, especially before the initiation of conventional synthetic DMARDs or biological and synthetic targeted DMARDs. This pre-treatment assessment includes the case history, laboratory and radiology findings as well. The physician must make sure a patient's vaccinations are up-to-date. The vaccines recommended for patients with CIR being treated with conventional synthetic DMARDs, bDMARDs, tsDMARDs and/or steroids should be given. Patient education is also very important. During workshops, they learn how to manage their drug treatments in at-risk situations and learn which symptoms require treatment discontinuation.

One-month humoral response following two or three doses of messenger RNA coronavirus disease 2019 vaccines as primary vaccination in specific populations in France: first results from the Agence Nationale Recherche contre le Sida (ANRS)0001S COV-POPART cohort.

OBJECTIVES: We aimed to investigate the 1-month humoral response to two or three doses of a messenger RNA coronavirus disease 2019 (COVID-19) vaccine as a primary vaccination regimen in specific populations compared with that in healthy adults. METHODS: Agence Nationale Recherche contre le Sida (ANRS)0001S-COV-POPART (NCT04824651) is a French nation-wide, multi-centre, prospective, observational cohort study assessing the immune response to COVID-19 vaccines routinely administered to 11 sub-groups of patients with chronic conditions and two control groups. Patients and controls who received at least two vaccine doses and whose results 1 month after the second dose were available were included. The humoral response was assessed 1 month after the first, second and third doses (if applicable) based on the percentage of responders (positive for anti-Spike severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2] IgG antibodies), geometric means of anti-Spike SARS-CoV-2 IgG antibodies (enzyme-linked immunosorbent assay) and proportion of participants with anti-SARS-CoV-2-specific neutralizing antibodies (in vitro neutralization assay for the original SARS-CoV-2 strain). All analyses were centralized. RESULTS: We included 4091 participants in this analysis: 2979 participants from specific sub-populations and 1112 controls. Only 522 (17.5%) participants from the specific populations received three doses as a primary vaccination regimen. Patients living with human immunodeficiency virus, cancer and diabetes had high percentages of responders after two doses, whereas patients with solid organ transplants, allogeneic hematopoietic stem cell transplants and hypogammaglobulinaemia had the lowest percentage of responders (35.9% [95% CI, 29.2-43.0], 57.4% [95% CI, 48.1-66.3] and 77.1% [95% CI, 65.6-86.3], respectively). In those who received the third dose, the percentage of responders reached 54.2% (95% CI, 42.9-65.2) (vs. 32.3% [95% CI, 16.7-51.4] after 2 doses) among those with solid organ transplants and 73.9% (95% CI, 58.9-85.7) (vs. 56.1% [95% CI, 46.2-65.7] after 2 doses) among those with hematopoietic stem cell transplants. Similar results were found with anti-SARS-CoV-2-specific neutralizing antibodies. CONCLUSIONS: A lower humoral response to COVID-19 vaccines was observed in the specific populations compared with that in the controls. The third dose of this vaccine in the primary regimen had a positive effect on the percentages of patients who developed anti-Spike IgG antibodies and specific neutralizing antibodies.

Risk of Cancer After Initiation of Targeted Therapies in Patients With Rheumatoid Arthritis and a Prior Cancer: Systematic Review With Meta-Analysis.

OBJECTIVE: To determine the risk of recurrent or new malignancy with exposure to targeted disease-modifying antirheumatic drugs (DMARDs) in adults with rheumatoid arthritis (RA), axial spondyloarthritis (SpA), or psoriatic arthritis (PsA) and a history of cancer. METHODS: We performed a systematic search of the literature for articles published up to June 2019 that investigated adults with RA, axial SpA, or PsA who had a history of cancer and received biologic or targeted synthetic DMARDs (bDMARDs or tsDMARDs). We compared the risk of relapse or occurrence of new cancer between patients with and without bDMARDs. Rate ratios (RRs) with 95% confidence intervals (95% CIs) were estimated. The heterogeneity of the studies was evaluated by the Cochran Q test and the I2 statistic. RESULTS: We included 24 observational studies of chronic inflammatory arthritis; of those, 12 were included in the meta-analysis of RA patients receiving bDMARDs. As compared with RA patients with a history of cancer and not receiving bDMARDs, for those receiving any bDMARD, the overall RR for risk of neoplasia was 1.09 (95% CI 0.92-1.32; P = 0.31, I2  = 8%); with tumor necrosis factor inhibitors, it was 1.11 (95% CI 0.85-1.46; P = 0.45, I2  = 48%); and with rituximab, it was 0.79 (95% CI 0.41-1.53; P = 0.49, I2  = 0%). The RR for risk of recurrence for skin cancer was 1.32 (95% CI 1.02-1.72; P = 0.04, I2  = 0%) and for breast neoplasia 1.21 (95% CI 0.84-1.72; P = 0.31, I2  = 0%). CONCLUSION: Apart from skin cancers including melanoma, the risk of recurrent or new cancer is not increased with the initiation of bDMARDs for RA as compared with no bDMARDs.

Hospitalizations for infections in primary Sjögren's syndrome patients: a nationwide incidence study.

BACKGROUND: Primary Sjögren's syndrome (pSS) is an autoimmune disease with increased risk of infections. Here, we assessed whether pSS patients were at higher risk of hospitalization for community and opportunistic infections. METHODS: We selected newly hospitalized pSS patients between 2011 and 2018, through a nationwide population-based retrospective study using the French Health insurance database. We compared the incidence of hospitalization for several types of infections (according to International Classification for Disease codes, ICD-10) between pSS patients and an age- and sex-matched (1:10) hospitalized control group. We calculated adjusted Hazard Ratios (aHR, 95% CI) adjusted on socio-economic status, past cardiovascular or lung diseases and blood malignancies factors. RESULTS: We compared 25 661 pSS patients with 252 543 matched patients. The incidence of hospitalizations for a first community infection was increased in pSS patients [aHR of 1.29 (1.22-1.31), p < .001]. The incidence of hospitalization for bronchopulmonary infections was increased in pSS patients [aHR of 1.50 (1.34-1.69), p < .001, for pneumonia]. Hospitalizations for pyelonephritis and intestinal infections were increased [aHR of 1.55 (1.29-1.87), p < .001 and 1.18 (1.08-1.29), p < .001, respectively]. Among opportunistic infections, only zoster, and mycobacteria infections (tuberculosis and non-tuberculous) were at increased risk of hospitalization [aHR of 3.32 (1.78-6.18), p < .001; 4.35 (1.41-13.5), p = .011 and 2.54 (1.27-5.06), p = .008, respectively]. CONCLUSIONS: pSS patients are at higher risk of hospitalization for infections. The increased risk of hospitalization for mycobacterial infections illustrates the potential bilateral relationship between the two conditions. Vaccination against respiratory pathogens and herpes zoster virus may help prevent some hospitalizations in pSS patients.KEY MESSAGESPrimary Sjögren's syndrome (pSS) increases hospitalization risk for community infections: bronchopulmonary, skin, dental, ear-nose-throat, intestinal infections and pyelonephritis.Hospitalizations for zoster and mycobacterial infections are also increased in this population.Dedicated preventive measures and vaccination campaigns could decrease the burden of infections in pSS patients.

Rheumatoid arthritis is associated with increased gut permeability and bacterial translocation which are reversed by inflammation control.

OBJECTIVE: to assess how rheumatoid arthritis (RA) and Disease Modifying Anti Rheumatic Drugs (DMARDs) affect gut permeability. METHODS: to explore colonic mucosa integrity, tight junction proteins ZO-1, occludin and claudin 2 were quantified by immunohistochemistry on colonic biopsies in 20 RA patients and 20 age- and sex-matched controls. Staining intensity was assessed by two blinded independent readers. To explore intestinal permeability, serum concentrations of LPS-binding protein (LBP), sCD14 and zonulin-related proteins (ZRP) were evaluated by ELISA in another cohort of 59 RA: 21 patients naive of DMARDs (17 before and after introduction of a conventional synthetic (cs) DMARDs), 38 patients with severe RA (before and after introduction of a biological (b) DMARDs), and 33 healthy controls. RESULTS: Z0-1 protein was less expressed in colon of RA patients than controls (mean score ± SEM of 1.6 ± 0.56 vs 2.0 ± 0.43; p= 0.01), while no significant difference was detected for occludin and claudin-2. RA patients had higher serum LBP and sCD14 concentrations than controls. LBP and sCD14 levels were significantly correlated with DAS28 (r = 0.61, p= 0.005 and r = 0.57, p= 0.01, respectively) while ZRP did not. bDMARD responders had significantly reduced LBP and sCD14 concentrations unlike bDMARDs non-responders and patients treated with csDMARDs. CONCLUSION: RA patients have altered colonic tight junction proteins and increased serum biomarkers of intestinal permeability. There was a correlation between serological markers of intestinal permeability and disease activity as well as bDMARD response. These results suggest a link between impaired gut integrity and systemic inflammation in RA.
