Background Therapeutic options for hospitalized patients with severe coronavirus disease 2019 (sCOVID-19) are limited. Preliminary data have shown promising results with baricitinib, but real-life experience is lacking. We assessed the safety and effectiveness of add-on baricitinib to standard-of-care (SOC) including dexamethasone in hospitalized patients with sCOVID-19. Methods This study is a 2-center, observational, retrospective cohort study of patients with sCOVID-19, comparing outcomes and serious events between patients treated with SOC versus those treated with SOC and baricitinib combination. Results We included 369 patients with sCOVID-19 (males 66.1%; mean age 65.2 years; median symptom duration 6 days). The SOC was administered in 47.7% and combination in 52.3%. Patients treated with the combination reached the composite outcome (intensive care unit [ICU] admission or death) less frequently compared with SOC (22.3% vs 36.9%, P  = .002). Mortality rate was lower with the combination in the total cohort (14.7% vs 26.6%, P  = .005), and ICU admission was lower in patients with severe acute respiratory distress syndrome (29.7% vs 44.8%, P  = .03). By multivariable analysis, age (odds ratio [OR] = 1.82, 95% confidence interval [CI] = 1.36–2.44, per 10-year increase), partial pressure of oxygen/fraction of inspired oxygen ratio (OR = 0.60, 95% CI = .52–0.68, per 10 units increase), and use of high-flow nasal cannula (OR = 0.34; 95% CI,.16–0.74) were associated with the composite outcome, whereas baricitinib use was marginally not associated with the composite outcome (OR = 0.52; 95% CI,.26–1.03). However, baricitinib use was found to be significant after inverse-probability weighted regression (OR = 0.93; 95% CI,.87–0.99). No difference in serious events was noted between treatment groups. Conclusions In real-life settings, addition of baricitinib to SOC in patients hospitalized with sCOVID-19 is associated with decreased mortality without concerning safety signals.

Objectives Predicting serious infections (SI) in patients with rheumatoid arthritis (RA) is crucial for the implementation of appropriate preventive measures. Here we aimed to identify risk factors for SI and to validate the RA Observation of Biologic Therapy (RABBIT) risk score in real-life settings. Methods A multi-centre, prospective, RA cohort study in Greece. Demographics, disease characteristics, treatments and comorbidities were documented at first evaluation and one year later. The incidence of SI was recorded and compared with the expected SI rate using the RABBIT risk score. Results A total of 1557 RA patients were included. During follow-up, 38 SI were recorded [incidence rate ratio (IRR): 2.3/100 patient-years]. Patients who developed SI had longer disease duration, higher HAQ at first evaluation and were more likely to have a history of previous SI, chronic lung disease, cardiovascular disease and chronic kidney disease. By multivariate analysis, longer disease duration (IRR: 1.05; 95% CI: 1.005, 1.1), history of previous SI (IRR: 4.15; 95% CI: 1.7, 10.1), diabetes (IRR: 2.55; 95% CI: 1.06, 6.14), chronic lung disease (IRR: 3.14; 95% CI: 1.35, 7.27) and daily prednisolone dose ≥10 mg (IRR: 4.77; 95% CI: 1.47, 15.5) were independent risk factors for SI. Using the RABBIT risk score in 1359 patients, the expected SI incidence rate was 1.71/100 patient-years, not different from the observed (1.91/100 patient-years; P = 0.97). Conclusion In this large real-life, prospective study of RA patients, the incidence of SI was 2.3/100 patient-years. Longer disease duration, history of previous SI, comorbidities and high glucocorticoid dose were independently associated with SI. The RABBIT score accurately predicted SI in our cohort.

Objectives Evidence on comorbidity prevalence in antiphospholipid syndrome (APS) and its difference from high comorbidity burden rheumatic diseases is limited. Herein, we compare multiple comorbidities between APS and RA. Methods A total of 326 patients from the Greek APS registry [237 women, mean age 48.7 (13.4) years, 161 primary APS (PAPS), 165 SLE-APS] were age/sex matched (1:2 ratio) with 652 patients from a Greek multicentre RA cohort of 3115 patients. Prevalence of cardiovascular (CV) risk factors, stroke, coronary artery disease (CAD), osteoporosis, diabetes mellitus (DM), chronic obstructive pulmonary disease (COPD), depression and neoplasms were compared between APS and RA patients using multivariate regression analysis. Results Ηyperlipidemia and obesity (ΒΜΙ ≥ 30 kg/m2) were comparable while hypertension, smoking, stroke and CAD were more prevalent in APS compared with RA patients. Osteoporosis and depression were more frequent in APS, while DM, COPD and neoplasms did not differ between the two groups. Comparison of APS subgroups to 1:2 matched RA patients revealed that smoking and stroke were more prevalent in both PAPS and SLE-APS vs RA. Hypertension, CAD and osteoporosis were more frequent only in SLE-APS vs RA, whereas DM was less prevalent in PAPS vs RA. Hyperlipidaemia was independently associated with CV events (combined stroke and CAD) in PAPS and SLE-APS, while CS duration was associated with osteoporosis in SLE-APS. Conclusion Comorbidity burden in APS (PAPS and SLE-APS) is comparable or higher than that in RA, entailing a high level of diligence for CV risk prevention, awareness for depression and CS exposure minimization.

The aim of this study is to review the available knowledge concerning the use of artificial Intelligence (AI) in general in different areas of Forensic Sciences from human identification to postmortem interval estimation and the estimation of different causes of death. This paper aims to emphasize the different uses of AI, especially in Forensic Medicine, and elucidate its technical part. This will be achieved through an explanation of different technologies that have been so far employed and through new ideas that may contribute as a first step to the adoption of new practices and to the development of new technologies. A systematic literature search was performed in accordance with the Preferred Reported Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines in the PubMed Database and Cochrane Central Library. Neither time nor regional constrictions were adopted, and all the included papers were written in English. Terms used were MACHINE AND LEARNING AND FORENSIC AND PATHOLOGY and ARTIFICIAL AND INTELIGENCE AND FORENSIC AND PATHOLOGY. Quality control was performed using the Joanna Briggs Institute critical appraisal tools. A search of 224 articles was performed. Seven more articles were extracted from the references of the initial selection. After excluding all non-relevant articles, the remaining 45 articles were thoroughly reviewed through the whole text. A final number of 33 papers were identified as relevant to the subject, in accordance with the criteria previously established. It must be clear that AI is not meant to replace forensic experts but to assist them in their everyday work life., Competing Interests: Conflicts of interest: In compliance with the ICMJE uniform disclosure form, all authors declare the following: Payment/services info: All authors have declared that no financial support was received from any organization for the submitted work.

Objectives: There are limited real-life data regarding the efficacy and safety of rituximab (RTX) as a remission-maintenance agent in microscopic-polyangiitis (ΜPA) and granulomatosis-with-polyangiitis (GPA). We aimed to estimate the incidence and risk factors for relapses, as well serious-adverse-events (SAEs) in MPA/GPA patients during RTX-maintenance., Methods: Retrospective cohort of newly-diagnosed/relapsing GPA/MPA patients who received RTX-maintenance (≥1 RTX-cycle, ≥6 months follow-up) following complete-remission (Birmingham-Vasculitis-Activity-Score-version-3 = 0 plus prednisolone ≤7.5 mg/day) with induction regimens. SAEs included serious-infections, COVID-19-associated hospitalizations, deaths, cardiovascular-events, malignancies and hypogammaglobulinemia. Incidence-rates (IR) and relapse-free survival through Kaplan-Meier plots were estimated. Cox-regression was conducted to investigate factors associated with the time-to-relapse., Results: 101 patients were included; 48% females, 69% GPA, 53% newly diagnosed, median age: 63 years. During follow-up (294.5 patient-years, median: 3 RTX-cycles), 30 relapses (57% major) occurred among 24 patients (24%, IR 10.2/100 patient-years). Kidney involvement (adjusted-Hazard-Ratio/aHR: 0.20; 95% CI: 0.06-0.74, p= 0.016), prior induction with RTX plus cyclophosphamide (vs RTX monotherapy: aHR = 0.02; 95% CI: 0.001-0.43, p= 0.012) and shorter time-interval until complete-remission (aHR = 1.07; 95% CI: 1.01-1.14, p= 0.023) were associated with decreased relapse-risk. We recorded 17 serious-infections (IR 5.8/100 patient-years), 11 COVID-19-associated hospitalizations (IR 3.7/100 patient-years), 4 malignancies (IR 1.4/100 patient-years), 6 cardiovascular-events (IR 2/100 patient-years) and 10 deaths (IR 3.4/100 patient-years)., Conclusion: In this real-world study, relapses during RTX-maintenance occurred in approximately in 1 out of 4 patients. Kidney involvement, induction with RTX plus cyclophosphamide and earlier achievement of complete-remission were associated with lower relapse-risk. Serious-infections rate was consistent with previous reports, whereas an increased rate of COVID19-associated hospitalizations was observed., (© The Author(s) 2024.

Despite the recent advances in treatment, antineutrophil cytoplasmic antibody (ANCA) associated vasculitides (AAV) are among the rheumatic diseases with the highest morbidity and mortality. These outcomes are affected by a variety of factors apart from the disease itself, and are driven by infections, cardiovascular disease and drug toxicity. Even after the induction of remission, patients and their treating physicians are challenged by frequent relapses, accrual of chronic damage and impaired quality of life. Given their rarity along with their heterogeneous disease spectrum, patient registries are of utmost need for the study of all aspects of AAV. Already established AAV registries have a significant contribution in the apprehension of these diseases outside the strict context of clinical trials, and are becoming increasingly important as new drugs and treatment strategies are about to be introduced in daily practice. We here describe the design of a contemporary, web-based and easy-to-use patient registry specifically for patients with AAV, including all the necessary domains suggested by international working groups. This project is anticipated to contribute in better understanding of AAV in our country, with a future prospect of contributing to and sharing data with other international registries., (© 2020 The Mediterranean Journal of Rheumatology (MJR).)

Objectives: Our primary objective was to study the long-term survival on drug (SOD) of patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) and ankylosing spondylitis (AS) treated with golimumab (GLM) in real life settings., Methods: This was a retrospective, observational study of all patients treated with GLM in 4 Academic Centres in Greece during a 4-year period (09/2010-06/2014). SOD was analysed using Kaplan-Meier survival analysis, while Cox regression analysis estimating hazard ratios (HRs) for different baseline variables associated with drug discontinuation was performed for each disease., Results: 328 patients (RA: 166, PsA: 82, AS: 80) were included. The estimated SOD at 2 and 3 years was 68% and 62% overall and was better for AS (79% and 76%) compared to RA (69% and 60%, p=0.067) and PsA (58% and 53%, p=0.001) patients; no difference was noted between RA and PsA patients (p=0.204). There was no difference in SOD between biologic-naïve and experienced nor between non-biologic co-treated or GLM monotherapy treated patients. Seropositivity (rheumatoid factor and/or anti-cyclic citrullinated peptide antibodies) was associated with a lower risk for GLM discontinuation by multivariate analysis (HR=0.5, 95% CI=0.0.25-1.1, p=0.05) in RA patients. During 606 patient-years of follow-up, 11 (3.3%) patients discontinued GLM due to adverse events (AE), accounting for 11% of treatment discontinuations. The rates of serious AEs and serious infections were 2.3 and 1.0/100-patient-years, respectively., Conclusions: In this real-life study, GLM showed a high 3-year SOD in patients with inflammatory arthritides with a low rate of discontinuation due to AEs.
