Risk of systemic lupus erythematosus flare after COVID-19 hospitalization: A matched cohort study.

OBJECTIVE: To analyze the risk of systemic lupus erythematosus (SLE) flare after admission for COVID-19. METHODS: We performed a matched cohort study using the Assistance Publique-Hôpitaux de Paris Clinical Data Warehouse which collects structured medical, biological and administrative information from 11 million patients in Paris area, France. Each SLE patient hospitalized with a COVID-19 diagnosis code between March 2020 and December 2021 was matched to one SLE control patient with an exact matching procedure using age ±3 years, gender, chronic kidney disease, end-stage renal disease, and serological activity. The main outcome was a lupus flare during the 6 months follow-up. A flare was considered if a) documented by the treating physician in the patient's EHR and b) justifying a change in SLE treatment. The electronic health records (EHRs) were individually checked for data accuracy. RESULTS: Among 4,533 SLE patients retrieved from the database, 81 (2.8%) have been admitted for COVID-19 between March 2020 and December 31, 2021, and 79 (n = 79/81,97.5%) were matched to a unique unexposed SLE. During follow-up, a flare occurred in 14 (17.7%) patients from the COVID-19 group as compared to 5 (6.3%) in the unexposed control group, including 4 lupus nephritis in the exposed group and 1 in the control group. After adjusting for HCQ use at index date and history of lupus nephritis, the risk of flare was higher in exposed SLE patients (hazard ratio [95% confidence interval] of 3.79 [1.49-9.65]). CONCLUSIONS: COVID-19 hospitalization is associated with an increased risk of flare in SLE.

Infliximab versus Cyclophosphamide for Severe Behçet's Syndrome.

BACKGROUND: Cyclophosphamide and infliximab are recommended as induction therapies for severe Behçet's syndrome. Whether infliximab is safer and more effective than cyclophosphamide in treating severe Behçet's syndrome is not known. METHODS: In this phase 2, Bayesian, multicenter randomized controlled trial, we assigned patients fulfilling the International Study Group's criteria for Behçet's syndrome who had major vascular or central nervous system involvement to receive either intravenous infliximab (5 mg/kg at weeks 0, 2, 6, 12, and 18) or cyclophosphamide (0.7 g/m2 intravenously at weeks 0, 4, 8, 12, 16, and 20, with a maximal dose of 1.2 g/infusion). All patients received the same glucocorticoid regimen. The primary outcome was complete response (clinical, biological, and radiological remission with a daily prednisone dose ≤0.1 mg/kg) at week 22. RESULTS: Between May 2018 and April 2021, 52 patients with severe Behçet's syndrome (n=37 [71%] with vascular Behçet's syndrome and n=15 [29%] with neuro-Behçet's syndrome) were randomly assigned to receive either infliximab or cyclophosphamide. Complete response was achieved by 22 out of 27 (81%) and 14 out of 25 (56%) patients in the infliximab and cyclophosphamide treatment groups, respectively (estimated difference, 29.8 percentage points; 95% credible interval, 6.6 to 51.7). The posterior probability that at least 70% of treated individuals achieved complete response by week 22 was 97.4% for infliximab and 6.0% for cyclophosphamide. Overall, adverse events were recorded in 8 out of 27 (29.6%) patients receiving infliximab and 16 out of 25 (64%) patients receiving cyclophosphamide (estimated difference, -32.3 percentage points; 95% credible interval, -55.2 to -6.6). Serious adverse events were reported in 15% and 12% of patients receiving infliximab and cyclophosphamide, respectively. CONCLUSIONS: Among patients with severe Behçet's syndrome, induction therapy with infliximab had a superior complete response rate at 22 weeks and fewer adverse events than induction with cyclophosphamide.

HPV Infection and Prevention in Patients With Immune-Mediated Inflammatory Diseases: A Scoping Review.

BACKGROUND/HISTORICAL PERSPECTIVE: Human papillomavirus (HPV) infections are a significant public health concern as they cause various cancers, including those of the cervix, vulva, vagina, anus, penis, and oropharynx, in both women and men. SUMMARY INTEGRATING THE CURRENT PUBLISHED LITERATURE: Individuals with immune-mediated inflammatory diseases, particularly systemic lupus erythematosus, have an increased risk of developing persistent HPV infection and subsequent precancerous lesions due to their immunosuppression. MAJOR CONCLUSIONS: Vaccination and screening for precancerous lesions are 2 central management strategies that must be implemented in patients with immune-mediated inflammatory diseases. Although HPV vaccination has been proven to be safe and effective in these patients, coverage remains low and should be encouraged. Screening for cervical cancer should be more widely implemented in this population, as recommended in guidelines for other immunosuppressed patients. FUTURE RESEARCH DIRECTIONS: Catch-up vaccination, vaginal self-sampling screening for HPV detection, and therapeutic vaccination are new options that should be considered.

Immunosuppressive agents or intravenous immunoglobulin in addition to glucocorticoids in the treatment of Susac syndrome: a French national cohort study.

BACKGROUND: Susac syndrome is a rare disease affecting mainly young women and is characterised by an occlusive microvessel disease limited to the brain, retina, and inner ear. No randomised controlled trial has been published or declared as ongoing to investigate treatments for Susac syndrome. We aimed to compare the effect of glucocorticoids given alone or in combination with immunosuppressive agents or intravenous immunoglobulin for the prevention of relapse in patients with Susac syndrome. METHODS: The Phenotypic and Etiological Characterization of Susac Syndrome-National Clinical Research Hospital Program study is a prospective national cohort study that started enrolling on Nov 29, 2011, and included all consecutive patients aged 18 years or older with Susac syndrome who were referred to the French reference centre (Department of Internal Medicine, Bichat-Claude Bernard Hospital, Paris). Susac syndrome was defined by either the triad of encephalopathy with typical brain MRI abnormalities, cochleo-vestibular damage, and multiple occlusions of retinal central artery branches, or at least two of the three criteria without any alternative diagnosis. Collected data included fundoscopy, retinal angiography, audiometry, cerebrospinal fluid, brain MRI, and treatment received at diagnosis; months 1, 3, 6, and 12 after diagnosis; and then annually for 5 years or in the case of a relapse. The primary outcome was defined as the first relapse occurring within a 36-month follow-up period from the first day of treatment, characterised by new clinical symptoms or signs, and new abnormalities observed on retinal angiography, audiometry, or brain MRI, necessitating treatment intensification. There was no involvement of people with lived experience at any stage. The study is registered at ClinicalTrials.gov, NCT01481662. FINDINGS: Between Nov 29, 2011, and Dec 2, 2022, 64 patients were included in the study, with a mean age at diagnosis of 35 years (SD 11); 41 (64%) were women and 23 (36%) were men. At diagnosis, 60 patients received glucocorticoids; 40 (63%) of 64 patients received glucocorticoids alone as a first-line therapy while 20 (31%) received glucocorticoids in combination with immunosuppressive agents or intravenous immunoglobulin. Overall, 46 (72%) of 64 patients had a first relapse with a median relapse-free survival time of 3·96 months (95% CI 2·24-16·07). Comparison of relapse-free survival showed no significant difference between the two treatment strategies (hazard ratio [HR] 1·11 [95% CI 0·56-2·17], p=0·76), compared with glucocorticoids alone as the reference group. In patients who first relapsed while treated with glucocorticoids alone, there was no significant difference in second relapse-free survival between those who did or did not receive immunosuppressive agents or intravenous immunoglobulin as a second-line therapy (HR 2·66 [95% CI 0·63-11·18], p=0·18). INTERPRETATION: The combination of glucocorticoids with immunosuppressive agents or intravenous immunoglobulin did not appear to reduce the risk of Susac syndrome relapse compared with glucocorticoids alone. Our findings did not support the systematic use of immunosuppressive agents in Susac syndrome. FUNDING: French Ministry of Health.

Criteria and non-criteria antiphospholipid autoantibodies screening in patients with late pregnancy morbidity: A cross-sectional study.

INTRODUCTION: Antiphospholipid syndrome (APS) is a cause of pregnancy morbidity. We aim to determine the frequency of criteria and non-criteria anti-phospholipid (aPL) autoantibodies in patients admitted for unexplained fetal death (UFD), pre-eclampsia (PE) and/or fetal growth restriction (FGR). METHODS: All consecutive patients with UFD, PE and/or FGR followed in the department of Obstetrics, Bichat Hospital, University of Paris, Paris, between January 2019 and December 2021 were screened. Patients with available serum stored from the index pregnancy were included. Patients with previously known APS or twin pregnancy were excluded. Testing for aPL autoantibodies included anti-cardiolipin (aCL), anti-ß2GPI (aß2GPI), anti-phosphatidylethanolamine (aPE), anti-phosphatidylserine/prothrombin (aPS/PT) IgG/IgM and anti-annexin V IgG. When available, placenta specimens were analyzed by a pathologist blinded to the aPL status. All clinical characteristics, pregnancy features, and comorbidities were extracted from electronic medical records. RESULTS: Overall 167 (32 (28.8-35.7) years) patients with UFD (n = 28; 16.8 %), PE (n = 60; 35.9 %) and/or FGR (n = 105; 62.9 %) were screened for aPL autoantibodies. Moderate titers of aPL autoantibodies were detected in 33 (n = 33/167, 19.8 %) patients. aPL autoantibodies were non-criteria aPE IgG/IgM in most cases (n = 28/33, 84.8 %). aPS/PT IgG/IgM were found in 11 (n = 11/33, 33.3 %) cases and aCL or aß2GP1 IgG/IgM in 4 (n = 4/33, 12.1 %). Multivariable logistic regression showed that aPL autoantibodies were mostly associated with UFD (OR 4.37 [1.72-11.20], p = 0.002), PE ≤ 34th week of gestation (3.22 [0.86-11.90], p = 0.070) and chronic deciduitis (8.03 [0.89-67.2], p = 0.060) DISCUSSION: The frequency of aPL autoantibodies, mostly aPE, is high in patients with late pregnancy morbidity and may qualify obstetrical APS.

Sarcoidosis immunopathogenesis - a new concept of maladaptive trained immunity.

Sarcoidosis is a chronic immune disease of unknown origin for which we still lack an immunological framework unifying causal agents, host factors, and natural history of disease. Here, we discuss the initial triggers of disease, and how myeloid cells drive granuloma formation and contribute to immunopathogenesis. We highlight recent advances in our understanding of innate immune memory and propose the hypothesis that maladaptive innate immune training connects previous environmental exposure to granuloma maintenance and expansion. Lastly, we consider how this hypothesis may open novel therapeutic avenues, while corticosteroids remain the front-line treatment.

PD-L1- and IL-4-expressing basophils promote pathogenic accumulation of T follicular helper cells in lupus.

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by anti-nuclear autoantibodies whose production is promoted by autoreactive T follicular helper (TFH) cells. During SLE pathogenesis, basophils accumulate in secondary lymphoid organs (SLO), amplify autoantibody production and disease progression through mechanisms that remain to be defined. Here, we provide evidence for a direct functional relationship between TFH cells and basophils during lupus pathogenesis, both in humans and mice. PD-L1 upregulation on basophils and IL-4 production are associated with TFH and TFH2 cell expansions and with disease activity. Pathogenic TFH cell accumulation, maintenance, and function in SLO were dependent on PD-L1 and IL-4 in basophils, which induced a transcriptional program allowing TFH2 cell differentiation and function. Our study establishes a direct mechanistic link between basophils and TFH cells in SLE that promotes autoantibody production and lupus nephritis.

Limb arteries involvement assessed by FDG/PET CT at diagnosis of giant cell arteritis and risk of relapse: An observational study.

INTRODUCTION: Steroids and anti-IL6 biotherapy are highly effective in obtaining remission in patients with giant cell arteritis (GCA) but the risk of relapses remains high. We aimed to identify predictors of relapse in GCA. METHODS: All consecutive patients admitted with a new diagnosis of GCA - according to the 2022 American College of Rheumatology/EULAR (ACR/EULAR) classification criteria - between May 2011 and May 2022 were eligible for this study. The primary outcome was the GCA relapse rate over the 36-months follow up. Factors associated with the primary outcome and time to first relapse were analyzed. RESULTS: One hundred and eight patients (74 [69-81] years, 64.8% women) with a new diagnosis of GCA were studied. GCA was biopsy-proven in 65 (60.2%) cases. Ninety-eight (90.7%) FDG/PET CT scans performed at diagnosis were available for review. All patients received steroids given for 21.0 [18.0-28.5] months, associated with methotrexate (n=1, 0.9%) or tocilizumab (n=2, 1.9%). During a median follow-up of 27.5 [11.4-35.0] months, relapse occurred in 40 (37%) patients. Multivariable Cox regression model, including general signs, gender, aortic wall thickness, FDG uptake in arterial wall and IV steroid pulse as covariates, showed that both general signs (HR 2.0 [1.0-4.0, P<0.05) and FDG uptake in limb arteries (HR 2.7 [1.3-5.5], P<0.01) at diagnosis were associated with GCA relapse. CONCLUSION: FDG uptake in limb arteries at diagnosis is a predictor of relapse in newly diagnosed GCA.

Chronic interstitial lung disease associated with systemic lupus erythematosus: A multicentric study of 89 cases.

BACKGROUND AND OBJECTIVE: Chronic interstitial lung disease (ILD) occurs rarely with systemic lupus erythematosus (SLE) as compared with other connective tissue diseases. This multicentric retrospective study of patients with SLE-ILD from the OrphaLung and French SLE networks during 2005-2020 aimed to describe the characteristics of patients with SLE-ILD and analyse factors associated with prognosis. METHODS: We analysed data for 89 patients with SLE-ILD (82 women, 92.1%) (median age at SLE diagnosis: 35 years [interquartile range 27-47]). All patients met the 2019 EULAR/ACR criteria for the diagnosis of SLE. RESULTS: Forty two (47.2%) patients were positive for anti-ribonuclear protein antibodies and 45 (50.6%) for anti SSA/Ro antibodies. A total of 58 (65.2%) patients had another connective tissue disease: Sjögren's syndrome (n = 33, 37.1%), systemic sclerosis (n = 14, 15.7%), inflammatory myopathy (n = 6, 6.7%), or rheumatoid arthritis (n = 6, 6.7%). ILD was diagnosed along with SLE in 25 (28.1%) patients and at a median of 6 (0-14) years after the SLE diagnosis. The most frequent CT pattern was suggestive of non-specific interstitial pneumonia (n = 41, 46.0%) with or without superimposed organizing pneumonia. After a median follow-up of 86.5 [39.5-161.2] months, 18 (20.2%) patients had died and 6 (6.7%) underwent lung transplantation. The median 5-year and 10-year transplantation-free survival were 96% (92-100) and 87% (78-97). In total, 44 (49.4%) patients showed ILD progression. Cutaneous manifestations and Raynaud's phenomenon were associated with better survival. Only forced vital capacity was significantly associated with survival and ILD progression. CONCLUSION: ILD is a rare manifestation of SLE with good overall prognosis but with possible risk of ILD progression. Patients with SLE-ILD frequently have another connective tissue disease.

Risk factors for severe hearing loss in Susac syndrome: A national cohort study.

BACKGROUND: Nonreversible hearing loss (HL) is the main sequelae of Susac syndrome (SuS). We aimed to identify risk factors for HL in SuS. METHODS: The CARESS study is a prospective national cohort study that started in December 2011, including all consecutive patients with SuS referred to the French reference center. The CARESS study was designed with a follow-up including fundoscopy, audiometry, and brain magnetic resonance imaging at 1, 3, 6, and 12 months after diagnosis and then annually for 5 years. The primary outcome was the occurrence at last follow-up of severe HL defined as the loss of 70 dB in at least one ear on audiometry or the need for hearing aids. RESULTS: Thirty-six patients (female 66.7%, median age 37.5 [range 24.5-42.5] years) included in the clinical study were analyzed for the primary outcome. Thirty-three patients (91.7%) had cochleovestibular involvement at SuS diagnosis including HL >20 dB in at least one ear in 25 cases. At diagnosis, 32 (88.9%), 11 (30.6%), and 7 (19.4%) patients had received steroids, intravenous immunoglobulin, and/or immunosuppressive (IS) drugs, respectively. After a median follow-up of 51.8 [range 29.2-77.6] months, 19 patients (52.8%) experienced severe HL that occurred a median of 13 [range 1.5-29.5] months after diagnosis. Multivariable analysis showed that the odds of severe HL were lower in patients who received IS drugs at diagnosis (OR 0.15, 95% CI 0.01-1.07, p = 0.058). CONCLUSIONS: Severe HL in SuS is associated with the absence of IS drugs given at diagnosis. Our findings support the systematic use of IS drugs in SuS.

High incidence of immune-mediated inflammatory diseases in sepsis survivors: A nationwide exposed-nonexposed epidemiological study.

OBJECTIVE: Sepsis is characterized by an excessive release of inflammatory cytokines. Cytokine dysregulation is pivotal to the pathophysiology of immune-mediated inflammatory diseases (IMIDs). We aimed to analyze the incidence of IMIDs in patients who survived sepsis. METHODS: We performed a matched-cohort study using the National Medico-Administrative Hospital database in order to analyze the association between sepsis and incident IMIDs in 2020 in France. Sepsis was defined by the combination of at least one infection diagnosis code and one organ failure code. Patients with a first sepsis diagnosed in 2020 were randomly matched with patients admitted during the same period for acute myocardial infarction (AMI) with an exact matching procedure using age, gender, and comorbidities as matching variables. The main outcome was an IMID diagnosis in a 9-month follow-up period starting the first day of hospitalization for sepsis or AMI. RESULTS: In France, the incidence rate of IMIDs after a sepsis in 2020-analyzed in 62,257 patients-was of 7956 (95% confidence interval [95% CI] 7392-8520) per 100,000 patient-years. As compared to the AMI population, we observed an increased risk for IMIDs of 2.80 (hazard ratio [HR]; 95% CI [2.22-3.54]) starting from day 16 after admission in the sepsis population. The risk of IMIDs onset in sepsis survivors depended on the type of IMIDs and was higher for immune thrombocytopenia (5.51 [1.97-15.4]), autoimmune hemolytic anemia (HR 4.83 [1.45-16.1]), and antineutrophil cytoplasmic antibody-associated vasculitis (4.66 [2.05-10.6]). Association between sepsis and IMIDs onset appeared well balanced across pathogen categories. CONCLUSION: Our study shows a high incidence of IMIDs among sepsis survivors.

Clinical presentation, course, and prognosis of patients with mixed connective tissue disease: A multicenter retrospective cohort.

OBJECTIVES: The objective of this study is to better characterize the features and outcomes of a large population of patients with mixed connective tissue disease (MCTD). METHODS: We performed an observational retrospective multicenter cohort study in France. Patients who fulfilled at least one diagnostic criterion set for MCTD and none of the criteria for other differentiated CTD (dCTD) were included. RESULTS: Three hundred and thirty patients (88% females, median [interquartile range] age of 35 years [26-45]) were included. The diagnostic criteria of Sharp or Kasukawa were met by 97.3% and 93.3% of patients, respectively. None met other classification criteria without fulfilling Sharp or Kasukawa criteria. After a median follow-up of 8 (3-14) years, 149 (45.2%) patients achieved remission, 92 (27.9%) had interstitial lung disease, 25 (7.6%) had pulmonary hypertension, and 18 (5.6%) died. Eighty-five (25.8%) patients progressed to a dCTD, mainly systemic sclerosis (15.8%) or systemic lupus erythematosus (10.6%). Median duration between diagnosis and progression to a dCTD was 5 (2-11) years. The presence at MCTD diagnosis of an abnormal pattern on nailfold capillaroscopy (odds ratio [OR] = 2.44, 95% confidence interval [95%CI] [1.11-5.58]) and parotid swelling (OR = 3.86, 95%CI [1.31-11.4]) were statistically associated with progression to a dCTD. Patients who did not progress to a dCTD were more likely to achieve remission at the last follow-up (51.8% vs. 25.9%). CONCLUSIONS: This study shows that MCTD is a distinct entity that can be classified using either Kasukawa or Sharp criteria, and that only 25.8% of patients progress to a dCTD during follow-up.

Incidence, risk factors and treatment of central nervous system immune reconstitution inflammatory syndrome in non-HIV patients with tuberculous meningitis: a multicentre observational study.

BACKGROUND: Immune reconstitution inflammatory syndrome (IRIS) affecting the central nervous system (CNS) is associated with poor outcomes. AIMS: To report on risk factors for CNS-IRIS following tuberculous meningitis (TBM) in HIV-negative patients. METHODS: In this retrospective multicentre study, all HIV-negative adult patients admitted between 2003 and 2021 with microbiologically proven TBM were included. The primary outcome measure was IRIS onset over follow-up. Characteristics of patients who developed IRIS were described. Factors associated with IRIS were identified using a multivariable logistic regression procedure. RESULTS: Fifty-six patients (33.0 (27.0-44.3) years, 39 (69.6%) men) with microbiologically proven TBM were studied. All patients received antituberculosis treatment and 48 (n = 48/56; 85.7%) steroids at TBM diagnosis. During a median follow-up of 18.0 (12.0-27.3) months, IRIS occurred in 28 (n = 28/56, 50.0%) patients, at a median time of 2.0 (1.0-3.0) months after antituberculosis treatment was started. IRIS involved the CNS in all but one case. Imaging revealed new (n = 23/28, 82.1%) and/or worsening (n = 21/28; 75.0%) of previously recognised lesions. Multivariable analysis showed that meningeal enhancement on brain magnetic resonance imaging (MRI) (odds ratio (OR): 15.3; 95% confidence interval (CI): (1.19-1193.5)) at TBM diagnosis and high blood albumin level (OR: 1.21; 95% CI: (1.02-1.60)) were associated with the occurrence of CNS-IRIS during follow-up. CONCLUSION: CNS-IRIS following TBM in non-HIV patients appears frequent and severe. Meningeal enhancement on brain MRI at tuberculosis diagnosis is a risk factor for CNS-IRIS.

N-Terminal pro-Brain Natriuretic Peptide is a biomarker for cardiovascular damage in systemic lupus erythematous: a cross-sectional study.

OBJECTIVES: Prediction models based on traditional risk factors underestimate cardiovascular (CV) risk in systemic lupus erythematosus (SLE). In a large sample of unselected SLE patients, we investigated cross-sectional associations of NT-proBNP with cardiovascular damage (CVD). METHODS: Serum NT-proBNP was measured in SLE patients enrolled in the MUHC Lupus Clinic registry. Serum were collected between March 2022 and April 2023 at annual research visits. The primary outcome was CVD identified on the SLICC Damage Index. Factors associated with CVD and NT-proBNP levels were determined. RESULTS: Overall, 270 SLE patients (female 91%, median age 50.7 [1st quartile- 3rd quartile : 39.6-62.1] years) were analyzed for the primary outcome. Among them, 33 (12%) had CVD. The ROC curve for NT-proBNP demonstrated strong associations with CVD (AUC 0.78, 95% CI 0.69-0.87) with a threshold of 133 pg/ml providing the best discrimination for those with/without CVD. Hypertension (OR 3.3, 95% CI 1.2-9.0), dyslipidaemia (OR 3.6, 95% CI 1.3-9.6) and NT-proBNP > 133 pg/ml (OR 7.0, 95% CI, 2.6-19.1) were associated with CVD in the multivariable logistic regression model. Increased NT-proBNP levels were associated with age (OR 4.2, 95% CI 2.2-8.3), ever smoking (OR 1.9, 95% CI 1.0-3.5), reduced eGFR (4.1, 95% CI 1.3-13.1), prior pericarditis/pleuritis (OR 2.5, 95% CI 1.4-4.5) and aPL antibodies (OR 2.6, 95% CI 1.4-4.9). CONCLUSION: NT-proBNP is a biomarker for CV damage in SLE. The novel associations of NT-proBNP levels with prior pericarditis/pleuritis and aPL antibodies suggest new avenues for research to better understand what drives CV risk in SLE.

Intravenous versus subcutaneous tocilizumab in Takayasu arteritis: multicentre retrospective study.

OBJECTIVES: In this large multicentre study, we compared the effectiveness and safety of tocilizumab intravenous versus subcutaneous (SC) in 109 Takayasu arteritis (TAK) patients. METHODS: We conducted a retrospective multicentre study in referral centres from France, Italy, Spain, Armenia, Israel, Japan, Tunisia and Russia regarding biological-targeted therapies in TAK, since January 2017 to September 2019. RESULTS: A total of 109 TAK patients received at least 3 months tocilizumab therapy and were included in this study. Among them, 91 and 18 patients received intravenous and SC tocilizumab, respectively. A complete response (NIH <2 with less than 7.5 mg/day of prednisone) at 6 months was evidenced in 69% of TAK patients, of whom 57 (70%) and 11 (69%) patients were on intravenous and SC tocilizumab, respectively (p=0.95). The factors associated with complete response to tocilizumab at 6 months in multivariate analysis, only age <30 years (OR 2.85, 95% CI 1.14 to 7.12; p=0.027) and time between TAK diagnosis and tocilizumab initiation (OR 1.18, 95% CI 1.02 to 1.36; p=0.034). During the median follow-up of 30.1 months (0.4; 105.8) and 10.8 (0.1; 46.4) (p<0.0001) in patients who received tocilizumab in intravenous and SC forms, respectively, the risk of relapse was significantly higher in TAK patients on SC tocilizumab (HR=2.55, 95% CI 1.08 to 6.02; p=0.033). The overall cumulative incidence of relapse at 12 months in TAK patients was at 13.7% (95% CI 7.6% to 21.5%), with 10.3% (95% CI 4.8% to 18.4%) for those on intravenous tocilizumab vs 30.9% (95% CI 10.5% to 54.2%) for patients receiving SC tocilizumab. Adverse events occurred in 14 (15%) patients on intravenous route and in 2 (11%) on SC tocilizumab. CONCLUSION: In this study, we confirm that tocilizumab is effective in TAK, with complete remission being achieving by 70% of disease-modifying antirheumatic drugs-refractory TAK patients at 6 months.

Improving Human Papillomavirus-Related Cervical Cancer Screening in Patients With Systemic Lupus Erythematosus.

Women with systemic lupus erythematosus (SLE), especially when exposed to immunosuppressive drugs, are at higher risk of human papillomavirus (HPV)-related cervical cancer.1 A recent study has shown that cervical cancer screening (CCS) coverage is worryingly low in this population.2.

Prognostic factors in giant cell arteritis associated aortitis with PET/CT and CT angiography at diagnosis.

BACKGROUND: Prognosis data on giant-cell arteritis (GCA)-associated aortitis are scarce and heterogeneous. The aim of this study was to compare the relapses of patients with GCA-associated aortitis according to the presence of aortitis on CT-angiography (CTA) and/or on FDG-PET/CT. METHODS: This multicenter study included GCA patients with aortitis at diagnosis; each case underwent both CTA and FDG-PET/CT at diagnosis. A centralized review of image was performed and identified patients with both CTA and FDG-PET/CT positive for aortitis (Ao-CTA+/PET+); patients with positive FDG-PET/CT but negative CTA for aortitis (Ao-CTA-/PET+), and patients solely positive on CTA. RESULTS: Eighty-two patients were included with 62 (77%) of female sex. Mean age was 67±8 years; 64 patients (78%) were in the Ao-CTA+/PET+ group; 17 (22%) in the Ao-CTA-/PET+ group and 1 had aortitis only on CTA. Overall, 51 (62%) patients had at least one relapse during follow-up: 45/64 (70%) in the Ao-CTA+/PET+ group and 5/17 (29%) in the Ao-CTA-/PET+ group (log rank, p = 0.019). In multivariate analysis, aortitis on CTA (Hazard Ratio 2.90, p = 0.03) was associated with an increased risk of relapse. CONCLUSION: Positivity of both CTA and FDG-PET/CT for GCA-related aortitis was associated with an increased risk of relapse. Aortic wall thickening on CTA was a risk factor of relapse compared with isolated aortic wall FDG uptake.
