CD19 CAR T-Cell Therapy in Autoimmune Disease - A Case Series with Follow-up.

BACKGROUND: Treatment for autoimmune diseases such as systemic lupus erythematosus (SLE), idiopathic inflammatory myositis, and systemic sclerosis often involves long-term immune suppression. Resetting aberrant autoimmunity in these diseases through deep depletion of B cells is a potential strategy for achieving sustained drug-free remission. METHODS: We evaluated 15 patients with severe SLE (8 patients), idiopathic inflammatory myositis (3 patients), or systemic sclerosis (4 patients) who received a single infusion of CD19 chimeric antigen receptor (CAR) T cells after preconditioning with fludarabine and cyclophosphamide. Efficacy up to 2 years after CAR T-cell infusion was assessed by means of Definition of Remission in SLE (DORIS) remission criteria, American College of Rheumatology-European League against Rheumatism (ACR-EULAR) major clinical response, and the score on the European Scleroderma Trials and Research Group (EUSTAR) activity index (with higher scores indicating greater disease activity), among others. Safety variables, including cytokine release syndrome and infections, were recorded. RESULTS: The median follow-up was 15 months (range, 4 to 29). The mean (±SD) duration of B-cell aplasia was 112±47 days. All the patients with SLE had DORIS remission, all the patients with idiopathic inflammatory myositis had an ACR-EULAR major clinical response, and all the patients with systemic sclerosis had a decrease in the score on the EUSTAR activity index. Immunosuppressive therapy was completely stopped in all the patients. Grade 1 cytokine release syndrome occurred in 10 patients. One patient each had grade 2 cytokine release syndrome, grade 1 immune effector cell-associated neurotoxicity syndrome, and pneumonia that resulted in hospitalization. CONCLUSIONS: In this case series, CD19 CAR T-cell transfer appeared to be feasible, safe, and efficacious in three different autoimmune diseases, providing rationale for further controlled clinical trials.

Sexual dysfunction in women with systemic autoimmune rheumatic disorders: a systematic review and meta-analysis.

OBJECTIVES: In women with systemic autoimmune rheumatic diseases (SARDs), female sexual dysfunction (SD) remains underestimated. We aimed to explore the prevalence and correlates of SD in females with SARDs. METHODS: We performed a systematic review and meta-analysis of studies assessing the prevalence of SD and the pooled Female Sexual Function Index (FSFI) scores in this setting (PROSPERO: CRD42021287346). We searched PubMed, EMBASE and Cochrane Central Register of Controlled Trials (CENTRAL) databases and grey literature until February 2022. We evaluated the quality of the selected records using the Hoy Risk of Bias tool. A random-effects meta-analysis of proportions with the double arcsine transformation was conducted. Subgroup and sensitivity analyses, as well as meta-regression of important correlates, were conducted. RESULTS: We included 68 studies with 5457 females diagnosed with a SARD (mean age: 43.7 [12.9] years). The overall SD prevalence was 63% (95% CI: 56, 69%, I2 = 94%) and the overall FSFI total score was 19.7 points (95% CI: 18.4, 21, I2 = 97%). Including only sexually active females, the SD prevalence was estimated as 60% (95% CI: 53, 67%, I2 = 88%), whereas the FSFI total score was 22 points (95% CI: 20.8, 23.1, I2 = 93%). Across the different SARDs, women with Sjögren's syndrome and systemic sclerosis reported the highest levels of SD (74%, 95% CI: 58, 87%, I2 = 84% and 69%, 95% CI: 54, 83%, I2 = 94%, respectively). CONCLUSION: Sexual function in females with SARDs seems to be severely impaired, irrespective of the type of SARD. Screening and treatment of SD in females with SARDs should become an integral part of healthcare clinical practice.

Tixagevimab/cilgavimab for the prevention of COVID-19 in vaccine-refractory patients with autoimmune diseases: a prospective cohort study.

OBJECTIVES: To investigate the effects of passive immunization with the anti-SARS-CoV-2 monoclonal antibodies tixagevimab/cilgavimab on humoral responses and on COVID-19 outcomes in vaccine-refractory patients with immune-mediated inflammatory diseases (IMID) at high risk of severe COVID-19. METHODS: A prospective cohort study was performed on a cohort of high-risk vaccine-refractory IMID patients treated with a single dose of tixagevimab/cilgavimab (150 mg/150 mg). COVID-19 outcomes as well as serum and salivary anti-SARS-CoV-2 IgG were assessed at baseline and for at least 6 months. Results were compared with an untreated high-risk vaccine-refractory IMID population. Standardised incidence ratios (SIR) of COVID-19 compared with the general population were calculated for both groups. RESULTS: 38 high-risk IMID patients received tixagevimab/cilgavimab and were compared with 114 untreated high-risk IMID controls. Serum anti-Spike IgG increased to 6.6 OD (SD: ±0.8) at day one and remained positive up to month 6 (6.3 ± 1.4 OD). Salivary anti-Spike IgG peaked at month 2 (1.6 ± 1.1 OD)) and decreased from month 3 (0.8 ± 0.3 OD)). No severe or extended infection was observed in the tixagevimab/cilgavimab group. Compared with the general population, the SIR of COVID-19 in treated patients was 0.76 (95% CI: 0.24-1.58) despite the increased risk profile. The SIR of the control group was 1.51 (1.07-2.02), corresponding to a significantly increased incidence. CONCLUSIONS: Passive immunization with tixagevimab/cilgavimab is safe and effective in inducing anti-SARS-CoV-2 immunity and potentially in preventing COVID-19 in high-risk vaccine-refractory IMID patients. These data provide a proof of concept for the use of monoclonal antibodies as a preventative strategy against SARS-CoV-2 in vulnerable populations.

[From conventional to cutting edge imaging in rheumatology]. / Von der konventionellen Bildgebung zum Cutting Edge Imaging in der Rheumatologie.

Imaging instruments, such as conventional X­ray, ultrasound and magnetic resonance imaging (MRI) are now fully established and highly valued in the care of rheumatology patients. However, the information provided by these imaging modalities in their current form is of limited utility for the prognostic prediction of individual patient outcomes. This article illuminates an important part of the development of imaging and shows that the vision of personalized medicine is becoming increasingly more tangible due to the further development of high-resolution imaging techniques, molecular imaging and artificial intelligence.

Renal Transplantation Improves Erectile Function in Patients with End-Stage Renal Disease: A Systematic Review and Meta-Analysis.

PURPOSE: Erectile dysfunction has a lower prevalence in renal transplant recipients compared to dialysis patients. Despite this observation, the effect of renal transplantation on erectile function remains unknown. We aimed to assess the role of renal transplantation on erectile function and to determine potential factors improving or deteriorating erectile dysfunction. MATERIALS AND METHODS: We conducted a systematic review and random effects meta-analysis of observational studies comparing erectile function preoperatively and postoperatively in renal transplant recipients (PROSPERO ID: CRD42020189580). Records reporting relevant outcomes were identified through search of PubMed®, Embase®, Cochrane Library and Scopus® databases from inception to September 2020. Judgment of the strength of evidence was performed with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS: We included 20 studies with 1,695 renal transplant recipients. At postoperative evaluation the number of patients with erectile dysfunction was reduced (RR 1.21, 95% CI 1.02-1.45, I2=88%). Renal transplant recipients reported an improvement in erectile function (RR 2.53, 95% CI 1.44-4.44, I2=90%) and the mean International Index of Erectile Function score increased by 3.04 points (95% CI 0.63-5.45, I2=96%) after renal transplantation. These effects were not demonstrated in the sensitivity analysis. In individuals reporting severe erectile dysfunction, no favorable effect of renal transplantation was observed (RR 1.51, 95% CI 0.85-2.68, I2=33%). For all outcomes the strength of evidence was considered low or very low due to methodological concerns and high heterogeneity among the included studies. CONCLUSIONS: Renal transplantation improves erectile function and the risk of erectile dysfunction reduces postoperatively compared to preoperatively. However, evidence on the matter is mostly based on low quality data. More studies with standardized outcomes are needed to validate and strengthen our findings.

Vascular endothelial injury assessed with functional techniques in systemic sclerosis patients with pulmonary arterial hypertension versus systemic sclerosis patients without pulmonary arterial hypertension: a systematic review and meta-analysis.

Microvascular dysfunction is one of the hallmarks of systemic sclerosis (SSc). The presence of pulmonary-arterial-hypertension (PAH) in SSc-patients is associated with poor prognosis. This is a systematic review and meta-analysis of studies assessing microvascular and endothelial injury with functional techniques in SSc-patients with PAH (SSc-PAH) compared to those without PAH (SSc-non-PAH) (PROSPERO: CRD42021236212). Literature search involved PubMed, the-Cochrane-Library, Web-of-Science, Scopus and manual search of article references. Studies assessing microvascular function by all available functional methods were considered eligible. Preclinical studies and studies using structural nailfold-videocapillaroscopy or biomarkers were excluded. Newcastle-Ottawa-Scale (NOS) was applied to evaluate the quality of retrieved studies. From a total of 602 retrieved articles, four studies (n = 159 participants) were included in meta-analysis; three studies were of high quality (NOS ≥ 7). In pooled analysis, a marginally significant impaired microvascular function was observed in SSc-PAH compared to SSc-non-PAH patients [SMD - 0.71, 95% CI (- 1.53, 0.12)], with significant between-study heterogeneity (I2 = 80%, p = 0.002). Among the studies examining endothelium-dependent and -independent vasodilation with LDF-iontophoresis, SSc-PAH subjects had significantly impaired endothelium-dependent-vasodilation [Ach-stimulated %change WMD - 216.79, 95% CI (- 337.87, - 95.71), I2 = 0%, p = 0.40], but no significant differences in endothelium-independent-vasodilation [SNP-stimulated %change WMD 90.84, 95% CI (- 82.52, 264.19), I2 = 44%, p = 0.18] compared with SSc-non-PAH subjects. In sensitivity analysis including only studies where SSc-PAH patients were diagnosed by right-heart-catheterization, a borderline difference between the two groups was noted [SMD - 1.09, 95% CI (- 2.30, 0.13), I2 = 82%, p = 0.004]. SSc-PAH patients showed marginally impaired microvascular function in the pooled analysis, as well as impaired endothelium-dependent-vasodilation in subgroup analysis compared with SSc-non-PAH patients. Vascular endothelial dysfunction could be involved in high cardiovascular risk of patients with SSc and PAH.

Ambulatory Blood Pressure Trajectories and Blood Pressure Variability in Diabetic and Non-Diabetic Chronic Kidney Disease.

BACKGROUND: Diabetic kidney disease is the leading cause of end-stage renal disease worldwide. Whether diabetes mellitus (DM) is an additional factor leading to elevated blood pressure (BP) levels and BP variability (BPV) in patients with chronic kidney disease (CKD) is unknown. This study aimed to compare ambulatory BP levels, BP trends and BPV in diabetic and non-diabetic patients with CKD. METHODS: This study included 48 diabetic and 48 non-diabetic adult patients (>18 years) with CKD (estimated glomerular filtration rate [eGFR] <90 and ≥15 mL/min/1.73 m2), matched in a 1:1 ratio for age, sex and eGFR within each CKD stage (2, 3a, 3b and 4). All patients underwent 24-h ambulatory BP measurement with the Mobil-O-graph device. To evaluate the effect of DM and time on the trajectories of 24-h BP levels, we performed two-way mixed ANOVA analysis for repeated measurements using hourly means. BPV was calculated with validated formulas. RESULTS: In total, patients with DM had significantly higher 24-h systolic BP (SBP; 132.13 ± 10.71 vs. 124.16 ± 11.45; p = 0.001) and pulse pressure (PP; 57.1 ± 9.6 vs. 49.5 ± 10.9; p < 0.001), but similar 24-h diastolic BP (DBP; 75.00 ± 8.43 vs. 74.62 ± 6.86 mm Hg; p = 0.809) compared to patients without DM. A similar trend was evident across all CKD stages. The effect of DM on BP trajectories during the recording period was significant for SBP (F = 18.766, p < 0.001, partial η2 = 0.261) and marginally significant for DBP (F = 3.782, p = 0.057, partial η2 = 0.067). Twenty-four hour SBP SD, weighted SD (wSD) and average real variability (ARV; 10.94 ± 2.75 vs. 9.46 ± 2.10; p = 0.004), as well as 24 h DBP SD, wSD, coefficient of variation (CV) and ARV (8.23 ± 2.10 vs. 7.10 ± 1.33; p = 0.002) were significantly higher in diabetic compared to non-diabetic CKD patients. CONCLUSIONS: Ambulatory SBP and PP levels are higher and SBP-profile is different in patients with diabetic compared to those with non-diabetic CKD. Systolic and diastolic BPV are also higher in diabetics. These findings may signify a higher cardiovascular risk for patients with both DM and CKD compared to patients with CKD alone, through higher BP levels and BPV.

IL-1 Inhibitors in the Treatment of Familial Mediterranean Fever: Treatment Indications and Clinical Features in a Large Real-World Cohort.

Background: The accruing evidence about the efficacy of anti-IL-1 agents in Familial Mediterranean Fever (FMF) patients led to their widespread off-label use. Therefore, identifying precise indications and clinical characteristics of IL-1i-warranting patients are important. This study investigated the clinical characteristics and treatment indications of patients with FMF requiring interleukin 1 inhibition therapy (IL-1i). Methods: Hospital records of FMF patients attending a tertiary care center at the Department of Rheumatology, University of Health Sciences, Basaksehir Cam and Sakura City Hospital were retrospectively analyzed. Data on symptoms and disease manifestations, age of symptom onset, time to diagnosis, MEFV variants, type of treatment, and their indications were collected. Results: Between June 2020 and March 2023, 312 FMF patients were identified. The mean age at the onset of symptoms was 14.0, and the mean time to diagnosis was 11.9 years. In total, 87.1% of patients were receiving colchicine monotherapy, while the remaining 11.8% warranted IL-1i. Clinical symptoms and flare manifestations did not show a significant difference between the two groups. However, patients receiving IL-1i started having symptoms at younger age (11.5 vs. 14.5, p = 0.042) and time to diagnosis was longer (18.2 vs. 11.0, p < 0.01). M694V homozygosity was more common in patients receiving IL-1i. Indications for patients receiving IL-1i were colchicine resistance (8.0%), secondary amyloidosis (5.1%), and colchicine intolerance (2.2%). Conclusions: This study shows that a subset of FMF patients, particularly those with a more severe phenotype with an earlier disease onset and M694V homozygosity, require IL-1i treatment despite the overall good efficacy and tolerability of colchicine, primarily due to colchicine resistance, intolerance, or complications such as amyloidosis.

Metabolic and molecular imaging in inflammatory arthritis.

It is known that metabolic shifts and tissue remodelling precede the development of visible inflammation and structural organ damage in inflammatory rheumatic diseases such as the inflammatory arthritides. As such, visualising and measuring metabolic tissue activity could be useful to identify biomarkers of disease activity already in a very early phase. Recent advances in imaging have led to the development of so-called 'metabolic imaging' tools that can detect these changes in metabolism in an increasingly accurate manner and non-invasively.Nuclear imaging techniques such as 18F-D-glucose and fibroblast activation protein inhibitor-labelled positron emission tomography are increasingly used and have yielded impressing results in the visualisation (including whole-body staging) of inflammatory changes in both early and established arthritis. Furthermore, optical imaging-based bedside techniques such as multispectral optoacoustic tomography and fluorescence optical imaging are advancing our understanding of arthritis by identifying intra-articular metabolic changes that correlate with the onset of inflammation with high precision and without the need of ionising radiation.Metabolic imaging holds great potential for improving the management of patients with inflammatory arthritis by contributing to early disease interception and improving diagnostic accuracy, thereby paving the way for a more personalised approach to therapy strategies including preventive strategies. In this narrative review, we discuss state-of-the-art metabolic imaging methods used in the assessment of arthritis and inflammation, and we advocate for more extensive research endeavours to elucidate their full field of application in rheumatology.

Fully Human Anti-CD19 CAR T Cells Derived from Systemic Lupus Erythematosus Patients Exhibit Cytotoxicity with Reduced Inflammatory Cytokine Production.

KYV-101 is an autologous anti-CD19 chimeric antigen receptor (CAR)-T cell therapy under investigation for patients with B-cell driven autoimmune diseases. Hu19-CD828Z is a fully human anti-CD19 CAR designed and demonstrated to have a favorable clinical safety profile. Since anti-CD19 CAR T cells target and kill B cells in both circulation and tissues, the treatment with Hu19-CD828Z CAR T cells offers great potential in depleting autoreactive B cells. Demonstrate that Hu19-CD828Z CAR T cells manufactured from cryopreserved leukaphereses from patients with systemic lupus erythematosus (SLE) exhibit CAR-mediated and CD19-dependent cytokine release, proliferation and cytotoxicity when co-cultured with autologous primary B cells. T cells were enriched from cryopreserved leukaphereses from SLE patients or healthy donors (HD). CAR T cells were generated by transducing these cells with a lentiviral vector encoding Hu19-CD828Z. CAR-mediated and CD19-dependent activity was monitored in vitro in a set of cytotoxicity, cytokine release, and proliferation studies, in response to autologous primary CD19+ B cells, a CD19+ cell line (NALM-6), or a CD19- cell line (U937). Hu19-CD828Z CAR T cells produced from SLE patients or HD induced greater proliferation and dose-dependent cytotoxicity against both autologous primary B cells and the CD19+ NALM-6 cells than nontransduced control T cells or co-cultures with a CD19- cell line. Interestingly, there was lower inflammatory cytokine production from SLE patient-derived CAR T cells compared to HD donor-derived CAR T cells with either CD19+ cells or primary B cells. Hu19-CD828Z CAR T cells generated from SLE patient lymphocytes demonstrate CAR-mediated and CD19-dependent activity against autologous primary B cells with reduced inflammatory cytokine production supporting KYV-101 as a novel potential therapy for the depletion of pathogenic B cells in SLE patients.

DeepNAPSI multi-reader nail psoriasis prediction using deep learning.

Nail psoriasis occurs in about every second psoriasis patient. Both, finger and toe nails can be affected and also severely destroyed. Furthermore, nail psoriasis is associated with a more severe course of the disease and the development of psoriatic arthritis. User independent quantification of nail psoriasis, however, is challenging due to the heterogeneous involvement of matrix and nail bed. For this purpose, the nail psoriasis severity index (NAPSI) has been developed. Experts grade pathological changes of each nail of the patient leading to a maximum score of 80 for all nails of the hands. Application in clinical practice, however, is not feasible due to the time-intensive manual grading process especially if more nails are involved. In this work we aimed to automatically quantify the modified NAPSI (mNAPSI) of patients using neuronal networks retrospectively. First, we performed photographs of the hands of patients with psoriasis, psoriatic arthritis, and rheumatoid arthritis. In a second step, we collected and annotated the mNAPSI scores of 1154 nail photos. Followingly, we extracted each nail automatically using an automatic key-point-detection system. The agreement among the three readers with a Cronbach's alpha of 94% was very high. With the nail images individually available, we trained a transformer-based neural network (BEiT) to predict the mNAPSI score. The network reached a good performance with an area-under-receiver-operator-curve of 88% and an area-under precision-recall-curve (PR-AUC) of 63%. We could compare the results with the human annotations and achieved a very high positive Pearson correlation of 90% by aggregating the predictions of the network on the test set to the patient-level. Lastly, we provided open access to the whole system enabling the use of the mNAPSI in clinical practice.

Efficacy of biologic agents for palmoplantar psoriasis: a systematic review and network meta-analysis.

BACKGROUND: Palmoplantar psoriasis (PP) represents a localized type of disease. While controversy over its' classification exists, a hyperkeratotic type, a pustular type and palmoplantar pustulosis (PPP) have been recognized. PP management is regularly supported by biologic agents. Our study aimed to review and synthesize available data regarding the efficacy of approved biologics for PP and PPP. RESEARCH DESIGN AND METHODS: A literature search was conducted in PubMed, CENTRAL, Scopus, and ClinicalTrilas.gov. Utilizing random-effects inverse-variance frequentist network meta-analyses (NMAs), we ranked interventions. The proportion of participants with cleared skin was the primary outcome. Fifty and 75% improvement in palmoplantar psoriasis area severity index (PPASI) were also explored (PPASI50, PPASI75). RESULTS: In total, 15 randomized controlled trials (RCTs) exploring the efficacy of on-label adalimumab, bimekizumab, etanercept, guselkumab, infliximab, ixekizumab, secukinumab, and ustekinumab were included. Data for PP were synthesized. Every biologic agent examined, except from infliximab, outperformed placebo. On-label secukinumab exhibited the highest probability of inducing complete resolution. Ixekizumab and infliximab ranked best on inducing PPASI50 and PPASI75. Our review supports that guselkumab is effective for PPP. CONCLUSIONS: Secukinumab, ixekizumab and infliximab are effective for PP. Research is warranted to produce evidence about the efficacy of biologics in PP and PPP.

Tolerability of low to moderate biomechanical stress during leisure sport activity in patients with psoriasis and psoriatic arthritis.

OBJECTIVES: To assess the impact of low to moderate biomechanical stress on entheses in patients with psoriasis and psoriatic arthritis (PsA). METHODS: We conducted a prospective interventional study on a cohort of psoriasis and PsA patients who underwent a 60 min badminton training session. Pain assessment by Visual Analogue Scale (VAS), physical examination of 29 entheses (SPARCC, LEI, MASES) and bilateral ultrasound at the lateral humeral epicondyle, inferior patellar pole and Achilles tendon were performed before and after training. Ultrasound changes were assessed using the OMERACT scoring system. A follow-up assessment of pain and adverse events was performed at 1 week. RESULTS: Sixteen patients were included (n=7 PsA; n=9 psoriasis) and 196 entheseal ultrasound scans were acquired. At baseline, median VAS pain (IQR) was 0.5 cm (0-2.3) and the total number of tender entheses was 12/464. Mean (min; max) Disease Activity Index for Psoriatic Arthritis was 6.1 (0.8; 19) and 5/7 PsA patients had an Minimal Disease Activity status. After training, no significant change in VAS pain (0.0 cm (0.0-2.0)) nor in tender entheses (13/464) emerged. Four patients (n=2 PsA, n=2 psoriasis) developed a grade-1 power Doppler-signal at six entheses, which, however, remained non-tender. At 1 week, median VAS pain remained stable (0.0 cm (0.0-3.0); p>0.05) and only one participant with active PsA at baseline reported increased arthralgias in three joints. CONCLUSIONS: Low to moderate physical strain, as in the context of leisure sport activity, seems well tolerated in psoriatic patients without increases in tenderness, pain and ultrasound-proven inflammation. Evidence-based recommendations for physical activity in PsA are direly needed and larger controlled studies should be conducted to define safe exercise thresholds.

Baricitinib Improves Bone Properties and Biomechanics in Patients With Rheumatoid Arthritis: Results of the Prospective Interventional BARE BONE Trial.

OBJECTIVE: Rheumatoid arthritis (RA) is characterized by erosive joint damage, deterioration of bone mass, and biomechanics. Preclinical evidence suggests a beneficial effect of Janus kinase inhibition (JAKi) on bone properties, but clinical data are scarce to date. In this study, we evaluated the effect of JAKi through baricitinib (BARI) on 1) volumetric bone mineral density (vBMD), bone microstructure, biomechanics, and erosion repair and 2) synovial inflammation in RA patients. METHODS: Prospective, single-arm, interventional, open-label, single-center phase 4 study in RA patients with pathological bone status and clinical indication of JAKi (BARE BONE trial). Participants received BARI (4 mg/day) over 52 weeks. To assess bone properties and synovial inflammation, high-resolution computed tomography scans and magnetic resonance imaging were performed at baseline (BL), week 24, and week 52. Clinical response and safety were monitored. RESULTS: Thirty RA patients were included. BARI significantly improved disease activity (Disease Activity Score in 28 joints using the erythrocyte sedimentation rate: 4.82 ± 0.90 to 2.71 ± 0.83) and synovial inflammation (RAMRIS synovitis score: 5.3 [4.2] to 2.7 [3.5]). We observed a significant improvement in trabecular vBMD with a mean change of 6.11 mgHA/mm3 (95% confidence interval [95% CI] 0.01-12.26). Biomechanical properties also improved with mean change from baseline in estimated stiffness of 2.28 kN/mm (95% CI 0.30-4.25) and estimated failure load of 98.8 N (95% CI 15.9-181.7). The number and size of erosions in the metacarpal joints remained stable. No new safety signals with BARI treatment were observed. CONCLUSION: Bones of RA patients improve with BARI therapy, as shown by an increase in trabecular bone mass and an improvement of biomechanical properties.

Imaging in inflammatory arthritis: progress towards precision medicine.

Imaging techniques such as ultrasonography and MRI have gained ground in the diagnosis and management of inflammatory arthritis, as these imaging modalities allow a sensitive assessment of musculoskeletal inflammation and damage. However, these techniques cannot discriminate between disease subsets and are currently unable to deliver an accurate prediction of disease progression and therapeutic response in individual patients. This major shortcoming of today's technology hinders a targeted and personalized patient management approach. Technological advances in the areas of high-resolution imaging (for example, high-resolution peripheral quantitative computed tomography and ultra-high field MRI), functional and molecular-based imaging (such as chemical exchange saturation transfer MRI, positron emission tomography, fluorescence optical imaging, optoacoustic imaging and contrast-enhanced ultrasonography) and artificial intelligence-based data analysis could help to tackle these challenges. These new imaging approaches offer detailed anatomical delineation and an in vivo and non-invasive evaluation of the immunometabolic status of inflammatory reactions, thereby facilitating an in-depth characterization of inflammation. By means of these developments, the aim of earlier diagnosis, enhanced monitoring and, ultimately, a personalized treatment strategy looms closer.

Cardiotoxicity of azithromycin in COVID-19: an overall proportion meta-analysis.

INTRODUCTION: To explore the incidence of pro-arrhythmic effects such as corrected QT interval (QTc) prolongation, arrhythmic events and myocardial injury of azithromycin as administered for the treatment of COVID-19. MATERIAL AND METHODS: We searched PubMed, the Cochrane Library and Web of Science databases from inception to 18 January 2021, as well as the medRχiv preprint database from 1 August 2020 to 18 January 2021, for studies exploring the cardiotoxicity effects of azithromycin, with or without concomitant use of hydroxychloroquine, in the context of Covid19. We performed a random effects single-arm meta-analysis of studies to calculate pooled proportion estimates for pro-arrhythmic effects. Meta-regression analyses were conducted to explain between-study heterogeneity. RESULTS: Thirty-four studies with a total of 3088 patients were included. Among 12 studies, the incidence of > 60ms QTc prolongation from baseline was 13% (95% CI 9%-18%, I² = 73%), whereas, among 28 studies, the incidence of QTc ≥ 500 ms at follow-up was 8% (95% CI 6%-11%, I² = 78%). Still, the discontinuation rate due to QTc prolongation was only 3% (95% CI 2%-5%, I² = 55%). The absolute risk of Torsade de pointes and ventricular tachycardia was 0.2% and 0.8%, respectively. Increased age, male sex, presence of hypertension or diabetes mellitus, use of QTc prolonging medication, prolonged baseline QTc interval and indicators of disease severity such as death explained between-study heterogeneity. CONCLUSIONS: Azithromycin, with or without hydroxychloroquine, leads to a significant risk for critical QTc prolongation in patients with Covid19. Due to its cardiotoxicity effects and its unproven efficacy in Covid19, azithromycin use should be limited to cases of bacterial co-infection.

Treatment of Sexual Dysfunction in Women with Systemic Autoimmune Rheumatic Disorders: A Systematic Review.

INTRODUCTION: Female sexual dysfunction (SD) is an under-recognized and undertreated problem in patients with systemic autoimmune rheumatic disorders (SARDs). OBJECTIVES: To summarize and evaluate the existing treatment modalities for SD in females with SARDs. METHODS: A systematic review was conducted following the PRISMA guidelines. Electronic databases were searched up to April 2022 for studies that assessed the use of pharmacological and non-pharmacological treatment modalities for the management of SD in females with SARDs. Randomized and observational studies were included. (PROSPERO: CRD42022296381). RESULTS: Seven studies with 426 females with SD were included. Seven different treatment modalities belonging to 5 different classes (androgen therapy, phosphodiesterase-5 inhibitors, exercise, education and local creams) were evaluated in patients with systemic lupus erythematosus, rheumatoid arthritis and systemic sclerosis. The majority of the studies were of low methodological quality. Standardized patient education and 8-week aerobic walking programs were successful in improving female SD. Local creams improved dyspareunia in females with systemic sclerosis. Testosterone did not significantly improve SD in patients with systemic lupus erythematosus. Accordingly, tadalafil did not result in a significant improvement of SD in females with systemic sclerosis, based on the Female Sexual Function Index. CONCLUSION: There is a lack of sufficient evidence to recommend a certain management strategy for SD in females with SARDs. Nonpharmacological therapy and lubricant creams may be beneficial in females with SARDs. No benefit was demonstrated after androgen therapy or tadalafil. Still, no definite conclusions can be drawn due to the important limitations of the available literature. Overall, our results may be considered preliminary and further research in the field is mandatory. Baniotopoulos P, Pyrgidis N, Minopoulou I, et al.

Nonpharmacological therapy and lubricant creams may be beneficial in females with SARDs. No benefit was demonstrated after androgen therapy or tadalafil. Still, no definite conclusions can be drawn due to the important limitations of the available literature. Overall, our results may be considered preliminary and further research in the field is mandatory.

Hepatic Fibrosis Is a Risk Factor for Greater Severity and Worse Outcome of Acute Ischemic Stroke.

Background: Nonalcoholic fatty liver disease, particularly in the presence of hepatic fibrosis, is associated with an increased risk of cardiovascular events, including ischemic stroke. However, it is unclear whether hepatic fibrosis is associated with the severity and outcome of acute ischemic stroke. Aim: To evaluate the relationship between hepatic fibrosis and the severity at admission and in-hospital outcome of acute ischemic stroke. Patients and methods: We prospectively studied all patients who were admitted to our department with acute ischemic stroke between September 2010 and February 2018 (n = 1107; 42.1% males, age 79.8 ± 7.2 years). The severity of stroke was assessed at admission with the National Institutes of Health Stroke Scale (NIHSS). Severe stroke was defined as NIHSS ≥ 21. The presence of hepatic fibrosis was evaluated with the Fibrosis-4 index (FIB-4). The outcome was assessed with dependency at discharge (modified Rankin Scale between 2 and 5) and with in-hospital mortality. Results: Patients with severe stroke had a higher FIB-4 index than patients with non-severe stroke (2.7 ± 1.7 and 2.3 ± 1.4, respectively; p < 0.05). Independent risk factors for severe IS were age (relative risk (RR) 1.064, 95% confidence interval (CI) 1.030−1.100, p < 0.001), female sex (RR 1.723, 95% CI 1.100−2.698, p = 0.012), atrial fibrillation (RR 1.869, 95% CI 1.234−2.831, p = 0.002), diastolic blood pressure (DBP) (RR 1.019, 95% CI 1.006−1.033, p = 0.001), and the FIB-4 index (RR 1.130, 95% CI 1.007−1.268, p = 0.022). At discharge, 64.2% of patients were dependent. The FIB-4 index did not differ between patients who were dependent and those who were independent at the time of discharge (2.3 ± 1.5 and 2.1 ± 1.2, respectively; p = 0.061). During hospitalization, 9.8% of patients died. Patients who died during hospitalization had a higher FIB-4 index than those who were discharged (2.9 ± 1.8 and 2.3 ± 1.4, respectively; p < 0.005). Independent risk factors for in-hospital mortality were DBP (RR 1.022, 95% CI 1.010−1.034, p < 0.001), serum glucose levels (RR 1.004, 95% CI 1.001−1.007, p = 0.007), serum triglyceride levels (RR 0.993, 95% CI 0.987−0.999, p = 0.023), NIHSS (RR 1.120, 95% CI 1.092−1.149, p < 0.001), and the FIB-4 index (RR 1.169, 95% CI 1.060−1.289, p = 0.002). Conclusions: Hepatic fibrosis, evaluated with the FIB-4 index, appears to be associated with more severe ischemic stroke and might also represent an independent risk factor for in-hospital mortality in patients admitted with acute ischemic stroke.

Intensity and longevity of SARS-CoV-2 vaccination response in patients with immune-mediated inflammatory disease: a prospective cohort study.

Background: Concerns have been raised about the reduced immunogenicity of vaccines against SARS-CoV-2 in patients with immune-mediated inflammatory diseases and the higher risk of breakthrough infections. The objective of our study was to investigate the intensity and longevity of SARS-CoV-2 vaccination responses in patients with immune-mediated inflammatory diseases, and to assess the effects of diagnosis, treatment, and adapted vaccination schedules. Methods: SARS-CoV-2 IgG antibody response after SARS-CoV-2 vaccination was measured over time in a large prospective cohort of healthy controls and participants with immune-mediated inflammatory diseases (attending or admitted to affiliated centres) between Dec 15, 2020, and Dec 1, 2021. Cohort participants with immune-mediated inflammatory diseases and control participants with no diagnosis of immune-mediated inflammatory diseases, were eligible for this analysis. Demographic data and disease-specific data were collected using a questionnaire. Humoral response was compared across treatment and disease groups, and with respect to the receipt of additional vaccinations. SARS-CoV-2 antibody response was measured by ELISA using optical density ratio units and modelled over time with age and sex adjustment using mixed-effects models. Using these models, marginal mean antibody titres and marginal risks of a poor response (optical density ratio <1·1) were calculated for each week starting from week 8 after the first vaccination to week 40. Findings: Among 5076 individuals registered, 2535 participants with immune-mediated inflammatory diseases (mean age 55·0 [15·2] years; 1494 [58·9%] women and 1041 [41·1%] men) and 1198 healthy controls (mean age 40·7 [13·5] years; 554 [46·2%] women and 644 [53·8%] men) were included in this analysis. Mean antibody titres were higher in healthy controls compared with people with immune-mediated inflammatory diseases at all timepoints, with a peak antibody response in healthy controls (mean optical density ratio 12·48; 95% CI 11·50-13·53) of more than twice that in participants with immune-mediated inflammatory diseases (5·50; 5·23-5·77; mean difference 6·98; 5·92-8·04). A poor response to vaccination was observed in participants with immune-mediated inflammatory diseases who were taking B-cell inhibitors (peak mean difference from healthy controls 11·68; 10·07-13·29) and T-cell inhibitors (peakmean difference from healthy controls 10·43; 8·33-12·53). Mean differences in antibody responses between different immune-mediated inflammatory diseases were small. Participants with immune-mediated inflammatory diseases who were given a third vaccine dose had higher mean antibody titres than did healthy controls vaccinated with two vaccine doses at 40 weeks after the initial vaccination (mean difference 1·34; 0·01-2·69). Interpretation: People with immune-mediated inflammatory diseases show a lower and less durable SARS-CoV-2 vaccination response and are at risk of losing humoral immune protection. Adjusted vaccination schedules with earlier booster doses or more frequent re-doses, or both, could better protect people with immune-mediated inflammatory diseases.
