ABSTRACT
Patients with immune-mediated inflammatory diseases are prone to steatotic liver disease (SLD), which has been observed in patients with psoriasis and hidradenitis suppurativa. We aimed to assess whether systemic lupus erythematosus (SLE) was associated with SLD and to define factors associated with SLD in SLE. This was a cross-sectional study, we included 106 consecutive patients with SLE who were seen in the rheumatology clinic between June 2021 and March 2022 and we chose two sex-paired controls for each SLE. All the participants underwent FibroScan and anthropometric assessments. SLD was defined as a controlled attenuation parameter ≥ 275dB/m. Prevalence of SLD was lower in patients with SLE (21.7% vs 41.5%, p < 0.001). Patients with SLE and SLD had a lower frequency of hydroxychloroquine use (65% vs 84%, p = 0.04), and higher C3 levels [123mg/dl (IQR 102-136) vs 99mg/dl (IQR 78-121), p = 0.004]. Factors associated with SLD in SLE were body mass index (BMI), waist circumference, glucose, and C3; hydroxychloroquine use was a protective factor. On univariate analysis, SLE was associated with a reduced risk of SLD (OR 0.39, 95%CI 0.23-0.67); however, after adjusting for age, BMI, waist, glucose, triglycerides, high-density cholesterol, low-density cholesterol, leukocytes, and hydroxychloroquine, it was no longer associated (OR 0.43, 95%CI 0.10-1.91). In conclusion, the prevalence of SLD in patients with SLE was not higher than that in the general population, and SLE was not associated with SLD. The factors associated with SLD were anthropometric data, glucose, hydroxychloroquine, and C3 levels.

INTRODUCTION: Sexual dysfunction (SD) is highly prevalent and multifactorial; nevertheless, recent research has shed light on a notable phenomenon: male patients with systemic lupus erythematosus (SLE) exhibit an elevated prevalence of sexual function disorders compared with the general population. Despite this recognition, the precise nature and extent of this association remain incompletely understood. OBJECTIVES: This comprehensive review aims to clarify the link by providing an overview of the fundamental components of normal male sexual function, delving into the pathogenesis of male SD and exploring the primary factors predisposing male SLE patients to SD. Additionally, the review offers insights into potential screening, diagnostic, and treatment strategies based on the current body of literature. METHODS: A meticulous search of relevant literature was conducted using the PubMed and Google Scholar databases. RESULTS: Studies exploring the correlation between SLE and SD in both genders have revealed a nearly 2-fold increased risk of SD among individuals with SLE compared with healthy counterparts. Moreover, these studies suggest that male SLE patients may have a higher susceptibility to SD, with reported prevalence ranging from 12% to 68%, compared with 0% to 22% in healthy individuals. Male patients with SLE are influenced by a spectrum of pathological factors, including pharmacological, psychological, and disease-related determinants, which, through their intricate interplay, elevate the likelihood of developing SD. CONCLUSION: Healthcare professionals must remain vigilant in understanding the intricacies of human sexuality and its dysfunction, particularly in males with SLE. The objective is to establish effective and potentially standardized methods for promptly diagnosing and optimally managing SD, recognizing its significant impact on the quality of life for males living with SLE. The pivotal role of rheumatologists in initiating discussions about sexual health, diagnosing SD, investigating causes, and implementing tailored strategies is underscored as crucial in addressing this multifaceted issue.

OBJECTIVES: To explore prevalence, characteristics and risk factors of COVID-19 breakthrough infections (BIs) in idiopathic inflammatory myopathies (IIM) using data from the COVID-19 Vaccination in Autoimmune Diseases (COVAD) study. METHODS: A validated patient self-reporting e-survey was circulated by the COVAD study group to collect data on COVID-19 infection and vaccination in 2022. BIs were defined as COVID-19 occurring ≥14 days after 2 vaccine doses. We compared BIs characteristics and severity among IIMs, other autoimmune rheumatic and non-rheumatic diseases (AIRD, nrAID), and healthy controls (HC). Multivariable Cox regression models assessed the risk factors for BI, severe BI and hospitalisations among IIMs. RESULTS: Among 9449 included response, BIs occurred in 1447 (15.3%) respondents, median age 44 years (IQR 21), 77.4% female, and 182 BIs (12.9%) occurred among 1406 IIMs. Multivariable Cox regression among IIMs showed age as a protective factor for BIs [Hazard Ratio (HR)=0.98, 95%CI = 0.97-0.99], hydroxychloroquine and sulfasalazine use were risk factors (HR = 1.81, 95%CI = 1.24-2.64, and HR = 3.79, 95%CI = 1.69-8.42, respectively). Glucocorticoid use was a risk factor for severe BI (HR = 3.61, 95%CI = 1.09-11.8). Non-White ethnicity (HR = 2.61, 95%CI = 1.03-6.59) was a risk factor for hospitalisation. Compared with other groups, patients with IIMs required more supplemental oxygen therapy (IIM = 6.0% vs AIRD = 1.8%, nrAID = 2.2%, and HC = 0.9%), intensive care unit admission (IIM = 2.2% vs AIRD = 0.6%, nrAID, and HC = 0%), advanced treatment with antiviral or monoclonal antibodies (IIM = 34.1% vs AIRD = 25.8%, nrAID = 14.6%, and HC = 12.8%), and had more hospitalisation (IIM = 7.7% vs AIRD = 4.6%, nrAID = 1.1%, and HC = 1.5%). CONCLUSION: Patients with IIMs are susceptible to severe COVID-19 BI. Age and immunosuppressive treatments were related to the risk of BIs.
ABSTRACT
OBJECTIVES: Disease flares in the post-coronavirus disease 2019 (COVID-19) vaccination period represent a prominent concern, though risk factors are poorly understood. We studied these flares among patients with idiopathic inflammatory myopathies (IIMs) and other autoimmune rheumatic diseases (AIRDs). METHODS: The COVAD-1 and -2 global surveys were circulated in early 2021 and 2022, respectively, and we captured demographics, comorbidities, AIRDs details, COVID-19 infection history and vaccination details. Flares of IIMs were defined as (a) patient self-reported, (b) immunosuppression (IS) denoted, (c) clinical sign directed and (d) with >7.9-point minimal clinically significant improvement difference worsening of Patient-Reported Outcomes Measurement Information System (PROMIS) PROMISPF10a score. Risk factors of flares were analysed using regression models. RESULTS: Of 15â165 total respondents, 1278 IIMs (age 63 years, 70.3% female, 80.8% Caucasians) and 3453 AIRDs were included. Flares of IIM were seen in 9.6%, 12.7%, 8.7% and 19.6% patients by definitions (a) to (d), respectively, with a median time to flare of 71.5 (10.7-235) days, similar to AIRDs. Patients with active IIMs pre-vaccination (OR 1.2; 95% CI 1.03, 1.6, P = 0.025) were prone to flares, while those receiving rituximab (OR 0.3; 95% CI 0.1, 0.7, P = 0.010) and AZA (OR 0.3, 95% CI 0.1, 0.8, P = 0.016) were at lower risk. Female gender and comorbidities predisposed to flares requiring changes in IS. Asthma (OR 1.62; 95% CI 1.05, 2.50, P = 0.028) and higher pain visual analogue score (OR 1.19; 95% CI 1.11, 1.27, P < 0.001) were associated with disparity between self-reported and IS-denoted flares. CONCLUSION: A diagnosis of IIMs confers an equal risk of flares in the post-COVID-19 vaccination period to AIRDs, with active disease, female gender and comorbidities conferring a higher risk. Disparity between patient- and physician-reported outcomes represents a future avenue for exploration.

OBJECTIVES: We investigated COVID-19 vaccine safety in pregnant and breastfeeding women with autoimmune diseases (AID) in the COVID-19 Vaccination in Autoimmune Diseases (COVAD) study. METHODS: Delayed-onset (>7 days) vaccine-related adverse events (AE), disease flares (DF), and AID-related treatment modifications were analyzed upon diagnosis of AID versus healthy controls (HC) and the pregnancy/breastfeeding status at the time of at least one dose of vaccine. RESULTS: Among the 9201 participants to the self-administered online survey, 6787 (73.8%) were women. Forty pregnant and 52 breastfeeding patients with AID were identified, of whom the majority had received at least one dose of COVID-19 vaccine (100% and 96.2%, respectively). AE were reported significantly more frequently in pregnant than in non-pregnant patients (overall AE 45% vs 26%, p= 0.01; minor AE 40% vs 25.9%, p= 0.03; major AE 17.5% vs 4.6%, p< 0.01), but no difference was found in comparison with pregnant HC. No difference was observed between breastfeeding patients and HC with respect to AE. Post-vaccination DF were reported by 17.5% of pregnant and 20% of breastfeeding patients, and by 18.3% of age- and disease-matched non-pregnant and non-breastfeeding patients (n = 262). All pregnant/breastfeeding patients who experienced a DF were managed with glucocorticoids; 28.6% and 20% of them required initiation or change in immunosuppressants, respectively. CONCLUSION: This study provides reassuring insights into the safety of COVID-19 vaccines administered to women with AID during the gestational and post-partum periods, helping overcome hesitant attitudes, as the benefits for the mother and the fetus by passive immunization appear to outweigh potential risks.
ABSTRACT
Limited evidence on long-term COVID-19 vaccine safety in patients with idiopathic inflammatory myopathies (IIMs) continues to contribute to vaccine hesitancy. We studied delayed-onset vaccine adverse events (AEs) in patients with IIMs, other systemic autoimmune and inflammatory disorders (SAIDs), and healthy controls (HCs), using data from the second COVID-19 Vaccination in Autoimmune Diseases (COVAD) study. A validated self-reporting e-survey was circulated by the COVAD study group (157 collaborators, 106 countries) from Feb-June 2022. We collected data on demographics, comorbidities, IIM/SAID details, COVID-19 history, and vaccination details. Delayed-onset (> 7 day) AEs were analyzed using regression models. A total of 15165 respondents undertook the survey, of whom 8759 responses from vaccinated individuals [median age 46 (35-58) years, 74.4% females, 45.4% Caucasians] were analyzed. Of these, 1390 (15.9%) had IIMs, 50.6% other SAIDs, and 33.5% HCs. Among IIMs, 16.3% and 10.2% patients reported minor and major AEs, respectively, and 0.72% (n = 10) required hospitalization. Notably patients with IIMs experienced fewer minor AEs than other SAIDs, though rashes were expectedly more than HCs [OR 4.0; 95% CI 2.2-7.0, p < 0.001]. IIM patients with active disease, overlap myositis, autoimmune comorbidities, and ChadOx1 nCOV-19 (Oxford/AstraZeneca) recipients reported AEs more often, while those with inclusion body myositis, and BNT162b2 (Pfizer) recipients reported fewer AEs. Vaccination is reassuringly safe in individuals with IIMs, with AEs, hospitalizations comparable to SAIDs, and largely limited to those with autoimmune multimorbidity and active disease. These observations may inform guidelines to identify high-risk patients warranting close monitoring in the post-vaccination period.

OBJECTIVE: Flares of autoimmune rheumatic diseases (AIRDs) following COVID-19 vaccination are a particular concern in vaccine-hesitant individuals. Therefore, we investigated the incidence, predictors and patterns of flares following vaccination in individuals living with AIRDs, using global COVID-19 Vaccination in Autoimmune Diseases (COVAD) surveys. METHODS: The COVAD surveys were used to extract data on flare demographics, comorbidities, COVID-19 history, and vaccination details for patients with AIRDs. Flares following vaccination were identified as patient-reported (a), increased immunosuppression (b), clinical exacerbations (c) and worsening of PROMIS scores (d). We studied flare characteristics and used regression models to differentiate flares among various AIRDs. RESULTS: Of 15 165 total responses, the incidence of flares in 3453 patients with AIRDs was 11.3%, 14.8%, 9.5% and 26.7% by definitions a-d, respectively. There was moderate agreement between patient-reported and immunosuppression-defined flares (K = 0.403, P = 0.022). Arthritis (61.6%) and fatigue (58.8%) were the most commonly reported symptoms. Self-reported flares were associated with higher comorbidities (P = 0.013), mental health disorders (MHDs) (P < 0.001) and autoimmune disease multimorbidity (AIDm) (P < 0.001).In regression analysis, the presence of AIDm [odds ratio (OR) = 1.4; 95% CI: 1.1, 1.7; P = 0.003), or a MHD (OR = 1.7; 95% CI: 1.1, 2.6; P = 0.007), or being a Moderna vaccine recipient (OR = 1.5; 95% CI: 1.09, 2.2; P = 0.014) were predictors of flares. Use of MMF (OR = 0.5; 95% CI: 0.3, 0.8; P = 0.009) and glucocorticoids (OR = 0.6; 95% CI: 0.5, 0.8; P = 0.003) were protective.A higher frequency of patients with AIRDs reported overall active disease post-vaccination compared with before vaccination (OR = 1.3; 95% CI: 1.1, 1.5; P < 0.001). CONCLUSION: Flares occur in nearly 1 in 10 individuals with AIRDs after COVID vaccination; people with comorbidities (especially AIDm), MHDs and those receiving the Moderna vaccine are particularly vulnerable. Future avenues include exploring flare profiles and optimizing vaccine strategies for this group.

To evaluate associations between the domains of the ANCA-associated vasculitis patient-reported outcome (AAV-PRO) instrument and clinical variables. Patients with granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), eosinophilic granulomatosis with polyangiitis (EGPA), or renal-limited vasculitis (RLV) were recruited from a tertiary care center in Mexico City. Demographic, clinical, serological, and treatment-related data were retrieved. Disease activity, damage, patient and physician global assessments (PtGA and PhGA) were evaluated. All patients completed the AAV-PRO questionnaire, male patients also completed the International Index of Erectile Function (IIEF-5) questionnaire. Seventy patients (44 women and 26 men) were included, with a median age of 53.5 years (43-61), and a disease duration of 82 months (34-135). Moderate correlations were identified between the PtGA and the AAV-PRO domains: social and emotional impact, treatment side effects, organ-specific symptoms, and physical function. The PhGA correlated with the PtGA and prednisone doses. Subanalyses of the AAV-PRO domains according to sex, age, and disease duration showed significant differences in the treatment side effects domain, with higher scores in women, in patients < 50 years, and in patients with disease duration < 5 years. The domain of concerns about the future showed a higher score in patients with disease duration < 5 years. A total of 17/24 (70.8%) of men who completed the IIEF-5 questionnaire were classified as having some degree of erectile dysfunction. The domains of AAV-PRO correlated with other outcome measures, while differences were found between some of the domains according to sex, age, and disease duration.

OBJECTIVE: Neutrophil infiltration into the synovial joint is a hallmark of rheumatoid arthritis (RA), a disease characterised by progressive bone erosion. However, the mechanisms by which neutrophils participate in bone destruction remain unclear. Carbamylation is a posttranslational modification linked to increased bone erosion in RA and we previously showed that carbamylation is present in RA neutrophil extracellular traps (NETs). However, it remains unclear whether NETs and their carbamylated protein cargo directly promote bone destruction and alter osteoclast biology. METHODS: NETs and carbamylated NETs (cNETs) were assessed for their capacity to induce osteoclast formation in CD14+ monocytes. Chemical inhibitors and neutralising antibodies were used to elucidate the pathway by which NETs induce osteoclastogenesis. HLA-DRB1*04:01 mice received intra-articular injection of cNETs for 4 weeks. Joints were isolated and assessed for osteoclast formation. Plasma and synovial fluid samples from patients with RA (n=32) were assessed for the presence of carbamylated histone, and correlations to disease specific outcomes were performed. RESULTS: We found that NETs, when cNETs, instruct monocytes to undergo rapid osteoclast formation. NET-mediated osteoclastogenesis appears to depend on Toll-like receptor 4 signalling and NET-associated proteins including histones and neutrophil elastase. In vivo, we identified that the number of osteoclasts increased following immunisation with cNETs in HLA-DRB1*04:01 transgenic mice. Furthermore, carbamylated histones are increased in plasma and synovial fluid from patients with RA and correlate with active bone resorption and inflammatory markers. CONCLUSIONS: Our results suggest that NETs have a direct role in RA-associated bone erosion by promoting osteoclast formation.

OBJECTIVE: COVID-19 vaccines have a favorable safety profile in patients with autoimmune rheumatic diseases (AIRDs) such as idiopathic inflammatory myopathies (IIMs); however, hesitancy continues to persist among these patients. Therefore, we studied the prevalence, predictors and reasons for hesitancy in patients with IIMs, other AIRDs, non-rheumatic autoimmune diseases (nrAIDs) and healthy controls (HCs), using data from the two international COVID-19 Vaccination in Autoimmune Diseases (COVAD) e-surveys. METHODS: The first and second COVAD patient self-reported e-surveys were circulated from March to December 2021, and February to June 2022 (ongoing). We collected data on demographics, comorbidities, COVID-19 infection and vaccination history, reasons for hesitancy, and patient reported outcomes. Predictors of hesitancy were analysed using regression models in different groups. RESULTS: We analysed data from 18 882 (COVAD-1) and 7666 (COVAD-2) respondents. Reassuringly, hesitancy decreased from 2021 (16.5%) to 2022 (5.1%) (OR: 0.26; 95% CI: 0.24, 0.30, P < 0.001). However, concerns/fear over long-term safety had increased (OR: 3.6; 95% CI: 2.9, 4.6, P < 0.01). We noted with concern greater skepticism over vaccine science among patients with IIMs than AIRDs (OR: 1.8; 95% CI: 1.08, 3.2, P = 0.023) and HCs (OR: 4; 95% CI: 1.9, 8.1, P < 0.001), as well as more long-term safety concerns/fear (IIMs vs AIRDs - OR: 1.9; 95% CI: 1.2, 2.9, P = 0.001; IIMs vs HCs - OR: 5.4 95% CI: 3, 9.6, P < 0.001). Caucasians [OR 4.2 (1.7-10.3)] were likely to be more hesitant, while those with better PROMIS physical health score were less hesitant [OR 0.9 (0.8-0.97)]. CONCLUSION: Vaccine hesitancy has decreased from 2021 to 2022, long-term safety concerns remain among patients with IIMs, particularly in Caucasians and those with poor physical function.

BACKGROUND: Splenectomy is a therapy for patients with treatment-refractory autoimmune cytopenias. Antiphospholipid antibodies (aPL) can be identified in 25%-85% of these patients. In this study, we sought to identify whether the presence of aPL was associated with worse outcomes in autoimmune cytopenia's patients who had undergone splenectomy. METHODS: We conducted a retrospective cohort study of patients who underwent splenectomy from 2000 to 2018. We describe clinical characteristics and outcomes in patients with autoimmune cytopenia's diagnosis with positive determinations of aPL. Additionally, we performed a case-control sub-analysis 1:1 of the cases with autoimmune cytopenia's matched control patients with negative aPL determination. RESULTS: A splenectomy was performed in 707 patients, of which we included 34 for the analysis. The median age at the time of splenectomy was 37 years (range 19-61), 53% corresponded to immune thrombocytopenia (ITP) and 47% to autoimmune hemolytic anemia (AIHA). Compared with controls (n = 34), patients had more treatment lines in addition to steroids (p = .02). There were no differences in complete response rate, 65% in cases and 80% in controls (p = .17). However, there was numerically a higher incidence of early infections (21% of cases vs. 3% controls, p = .05). During the entire follow-up, 15% of aPL patients compared with 9% of control patients had a thrombotic event (p = .70). DISCUSSION: Splenectomy for treatment-refractory autoimmune cytopenia's patients with persistent aPL is an effective treatment despite some safety concerns related to early infections. These results suggest that the presence of aPL should not impact the decision to undergo splenectomy.

OBJECTIVES: Our study aims to describe the association between SLE and sexual function, analysing demographic variables, comorbidities and other disease-related factors. As an exploratory objective, the impact of asking about sexual function during outpatient consultation was evaluated. METHODS: From 2018 to 2019, we invited sexually active men diagnosed with SLE to complete questionnaires that evaluated their sexual function and quality of life. Additionally, patients were asked if they believed they had sexual dysfunction, whether they would be interested in receiving specialized sexual care, and if they considered SLE to be detrimental to their sexual function. Epidemiological and disease-related data were retrieved from the patients' clinical records. RESULTS: We included 124 men with SLE. Twenty-two (18%) patients answered positively when asked if they believed they had sexual dysfunction. These patients had lower overall erectile function scores and lower physical function scores than those who did not consider they had sexual dysfunction. In the multivariable analysis, factors that were associated with better sexual function were high physical function (B = 0.126, p = .031), lower BMI (B = 0.53, p = .010) and the patient's perception of normal sexual function (B = 13.0, p < .001). Comorbidities associated with worse sexual function were type 2 diabetes (B = -8.1, p = .017) and a history of thrombosis (B = -5.12, p = .019). CONCLUSION: Sexual function of male patients with SLE is impaired, independently of disease activity, chronic disease damage or pharmacological treatment. A simple question about perception of sexual function in the outpatient clinic can be used to help determine which patients could benefit from a multidisciplinary intervention to improve sexual health.

Primary meningococcal septic arthritis (PMSA) is an extremely rare local infection by Neisseria meningitidis in the absence of meningitis or meningococcaemia syndrome. A 30-year-old healthy, immunocompetent man presented with arthralgia, fever, chest rash, and significant swelling of the right knee. On admission, a disseminated maculopapular and purpuric rash, oligoarthritis, neutrophilia, and elevated acute phase reactants were documented. Following arthrocentesis of the right knee, isolation of N. meningitidis and the presence of calcium oxalate crystals in the synovial fluid were reported. The diagnosis of PMSA was made. Histological analysis of the skin lesion showed leucocytoclastic vasculitis. He was treated with intravenous ceftriaxone plus open surgical drainage and ambulatory cefixime with adequate response. After 1 month, he presented resolution of the pathological process. We performed an extensive review of the literature, finding that the key elements supporting the diagnosis of PMSA are prodromal upper respiratory tract symptoms and skin involvement prior to or synchronous with the arthritis. Also, the most frequently involved joint is the knee. This report is the first case of a patient presenting with PMSA associated with calcium oxalate crystals in the synovial fluid. Herein, we discuss the most frequent clinical manifestations, the unusual histological features, the recommended treatment, and the reported prognosis of this rare entity.

Latin America is experiencing a demographic and epidemiological transition, with an increase in non-communicable diseases such as cancer. One of the greatest advances in the therapeutic approach to cancer has been the discovery of immunotherapy, and specifically of checkpoint inhibitors (CPIs). Since inhibition of CTLA-4 and PD-1/PD-L1 enhances the immune response, cancer immunotherapies are associated with a new class of toxicities of autoimmune and/or autoinflammatory origin. These immune-related adverse events (irAEs) result in a broad spectrum of clinical events including rheumatic clinical syndromes, which may resemble classic rheumatic diseases. The most common rheumatic manifestations include inflammatory arthritis, myositis, vasculitis, and sicca syndrome. Recognizing rheumatologic irAEs is challenging due to the wide spectrum of clinical presentations that often do not fulfill traditional classification criteria of rheumatic diseases. A delayed diagnosis and treatment can lead to long-term disability, and disorders may become chronic and require ongoing immunosuppressive therapy. The management of irAEs includes the prompt detection and appropriate grading since their management is dictated by their severity. The growing use of CPIs, and the ensuing increase in irAEs, warrants an increasing collaboration between rheumatologists and oncologists. Understanding the pathophysiology, diagnosis, grading, and therapeutic implications of irAEs in patients with cancer is thus a requirement for Latin American oncologists and rheumatologists alike.

Objective: Antibodies against carbamylated proteins (anti-CarP) are associated with poor prognosis and the development of bone erosions in rheumatoid arthritis (RA). RA neutrophils externalize modified autoantigens through the formation of neutrophil extracellular traps (NETs). Increased levels of the cathelicidin LL37 have been documented in the synovium of RA patients, but the cellular source remains unclear. We sought to determine if post-translational modifications of LL37, specifically carbamylation, occur during NET formation, enhance this protein's autoantigenicity, and contribute to drive bone erosion in the synovial joint. Methods: ELISA and Western blot analyses were used to identify carbamylated LL37 (carLL37) in biological samples. Anti-carLL37 antibodies were measured in the serum of HLA-DRB1*04:01 transgenic mice and in human RA synovial fluid. Results: Elevated levels of carLL37 were found in plasma and synovial fluid from RA patients, compared to healthy controls. RA NETs release carLL37 and fibroblast-like synoviocytes (FLS) internalized NET-bound carLL37 and loaded it into their MHCII compartment. HLA-DRB1*04:01 transgenic mice immunized with FLS containing NETs developed autoantibodies against carLL37. Anti-carLL37 antibodies were present in RA sera and synovial fluid and they correlated with radiologic bone erosion scores of the hands and feet in RA patients. CarLL37-IgG immune complexes enhanced the ability of monocytes to differentiate into osteoclasts and potentiated osteoclast-mediated extracellular matrix resorption. Conclusions: NETs are a source of carLL37 leading to induction of anti-carbamylated autoantibody responses. Furthermore, carLL37-IgG immune complexes may be implicated in the bone damage characteristic of RA. These results support that dysregulated NET formation has pathogenic roles in RA.

OBJECTIVE: To determine the factors associated with anxiety, depression, and concern within the COVID-19 pandemic in a population with autoimmune diseases. METHODS: A telephonic survey was conducted during the early stages of the pandemic in a tertiary care center, which included patients with systemic autoimmune diseases. Mental health variables were assessed with Patient Health Questionnaire 2, General Anxiety Disorder 7 scores, and pandemic-related concern questions. Sociodemographic aspects were also evaluated. RESULTS: Of the total 334 participants, 291 (87.1%) were women, with a median age of 46 years; systemic lupus erythematosus (SLE) was the most frequent diagnosis (144, 43.2%); 44 patients (13.2%) showed depression and 32 (9.6%) anxiety. The variables associated with depression were all the pandemic concern items, body mass index, anxiety, and a higher COVID-19 symptom score. Anxiety was associated with depression, all pandemic concern items, and a higher COVID-19 symptom score. Women presented higher scores in all concern items. The SLE group presented higher scores in concern questions and difficulty finding medication. CONCLUSION: During the COVID-19 outbreak, rheumatic patients are vulnerable to psychiatric conditions, which makes it imperative for physicians who treat these patients to pay careful attention in order to detect them promptly and to settle coping strategies.

We describe the case of a 50-year-old woman with a history of SLE and APS that presented with a spontaneous subdural haematoma, prolonged aPTT, PT and INR and positive LA. The activity of the coagulation factors II, VIII, IX and XI was extremely low, and anti-prothrombin antibody IgG was positive. LAHS was established, with inhibition of the intrinsic pathway, as an acquired haemophilia. The patient received corticosteroids and cyclophosphamide as treatment. To the best of our knowledge, this is one of the few reports of spontaneous intracranial bleeding, an unusual and initial manifestation of LAHS in an adult patient.HighlightsLAHS is characterised by the presence of LA and hypoprothrombinaemia caused by anti-prothrombin antibodies.Prolonged aPTT and INR, and positive LA are important laboratory findings that help the suspicion of LAHS.Intracranial bleeding is an unusual manifestation of LAHS associated with low factor II activity.Corticosteroids are the first-line treatment of LAHS.The prognosis of LAHS is good with adequate treatment, with a reported mortality of 5%.

INTRODUCTION/OBJECTIVES: Cutaneous involvement is often overlooked in rheumatoid arthritis (RA). We described cutaneous findings in outpatients attending a recent-onset cohort and identified factors associated with skin involvement and reduced (R) dermatological quality of life (DQoL). METHODS: Skin and rheumatological examinations were performed in 122 patients. DQoL was assessed through the Dermatology Life Quality Index (DLQI). Skin findings were classified as RA-specific and RA-nonspecific. Multiple regression analysis identified factors associated to skin involvement and RDQoL (DLQI score > 1). RESULTS: Patients were middle-aged females (91%), with a 1-year mean disease activity score in 28 joints as 2.0 (interquartile range: 1.5-2.6). There were 94 (77%) patients in whom at least one cutaneous finding was observed: 17 (13.1%) had RA-specific findings (all were rheumatoid nodules) and 91 (96.8%) had at least one RA-nonspecific finding, further classified into skin diseases (35.2%), hair diseases (20.9%), and skin-related signs (76.9%, among whom 94.3% had xerosis). Age (odds ratio [OR]: 1.054, 95% confidence interval [CI]: 1.015-1.094) and skin-health concerns (OR: 5.657, 95% CI: 1.771-18.070) were associated with cutaneous involvement, whereas increased age and DLQI score were associated with a higher number of skin findings/patient. There were 29 patients (24.2%) with RDQoL, which were associated with the Short Form-36 emotional component (OR: 0.955, 95% CI: 0.923-0.988) and the number of skin findings/patient (OR 2.873, 95% CI 1.723-4.791). Pruritus and hair diseases were the individual categories associated with RDQoL. CONCLUSIONS: Cutaneous manifestations are frequent in RA patients and have the potential to impact the emotional component of health-related quality of life. Key Points ⢠Up to 77% of the RA patients with substantial follow-up, from a recent-onset disease cohort, had cutaneous manifestations; these were primarily RA-nonspecific findings, whereas 13.1% had RA-specific findings. ⢠Skin-health concerns and age were associated with cutaneous involvement; meanwhile, increased age and Dermatology Life Quality Index (DLQI) score were associated with a higher number of cutaneous findings/patient. ⢠Reduced dermatological quality of life (RDQoL) was documented in one in four patients and was associated with the SF-36 emotional component and the number of cutaneous findings/patient.
