Project description:BackgroundSystemic lupus erythematosus (SLE) is a chronic disease characterised by autoimmunity and increased susceptibility to infections. COVID-19 is a systemic viral disease currently spreading as a pandemic. Little is known about the impact of COVID-19 in patients with SLE.Objectiveto acquire information on the impact of COVID-19 in SLE.MethodsA 26-item anonymous questionnaire investigating demographics, SLE clinical features, COVID-19 diagnoses and changes in treatments and daily habits was administered to patients with SLE from three referral centres through www.surveymonkey.com over 10 days. Data from the survey were compared to those from published estimates about the general population.ResultsFour-hundred-seventeen patients responded to the survey. More than 60% of subjects complained of symptoms that are also associated to COVID-19. Fourteen COVID-19 diagnoses (five confirmed by polymerase chain reaction) were reported, in contrast to a 0.73% prevalence of confirmed cases in Lombardy. One hospitalisation was reported. Fever, anosmia, dry cough, a self-reported history of neuropsychiatric SLE and a recent contact with confirmed COVID-19 cases were more strongly associated with COVID-19, as were symptoms and lower compliance to behavioural preventive measures in patients' contacts. No protective effect was seen in subjects on hydroxychloroquine.ConclusionCOVID-19 morbidity might only moderately be increased in most patients with SLE, although limited information can be inferred on more severe cases. Hydroxychloroquine apparently seems not to confer protection to infection per se, although other beneficial roles cannot be excluded. Containment policies and behavioural preventive measures could have a major role in limiting the impact of COVID-19 in patients with SLE.

Project description:BackgroundPatients with chronic diseases are potential candidates for inadequate follow-up of drug therapy, tending to incur damage to the intended results. This deserves greater attention in the pandemic period, as they are in the considered risk group.MethodsWe aim to assess Treatment Adherence Measure and analyze associations with characteristics related to the patient, treatment, disease, health professionals and service, and sociodemographic issues in patients with Systemic Lupus Erythematosus (SLE). W conducted a cross-sectional study with a sample of 116 participants, whose data were collected through individual interviews and review of medical records, during the first months of the COVID-19 pandemic in Brazil. Adherence was measured using the Treatment Adherence Measure, and associations were evidenced through described and inferential statistics.ResultsThe percentage of adherent patients was 55.2%. An association was found between MTA (Medication Treatment Adherence) and physical exercise practice (p = 0.032), and difficulties with treatment (p = 0.002). Conclusion: Participants who did not practice physical exercise were 3.71 times more likely to not adhere to the treatment. Individuals who identified difficulties in the treatment were 3.43 times more likely to not adhere to the treatment; we believe that the pandemic may have influenced this result. More targeted studies are needed to measure the impact on MTA in these patients.

Project description:A new strain of coronavirus (COVID-19) emerged in 2020 changing the way the nation looked, worked and lived. In response to this unprecedented COVID-19 pandemic, the Army Nurse Corps (ANC) reexamined our capabies and agility to respond to a new and rapidly evolving environment. Maintaining the pivot to readiness, providing sustainable support and protecting our most valuable asset-our people-were and continues to be in the forefront of leaders' thoughts as we faced this invisible adversary. With every new challenge, lessons learned provide an opportunity to re-examine challenges and successes of the response to COVID-19. Organizational restructuring, balancing risks, expanding capabilities and educational platforms were reassessed and adjusted to fill the needs of the environment as they evolved. The year 2020 will stand throughout history as another example where our readiness, resilience, and flexibility as an Army Nurse Corps was tried and tested. We demonstrated our ability to adapt and overcome-displaying our willingness to stand up as part of the Army Medicine Team and face an unknown adversary to protect the nation we vowed to serve.

Project description:Little is known about the impact of coronavirus disease 2019 (COVID-19) pandemic to the care of patients with systemic lupus erythematosus (SLE) in the long-term. By crossing population data with the results of a web-based survey focused on the timeframes January-April and May-December 2020, we found that among 334/518 responders, 28 had COVID-19 in 2020. Seventeen cases occurred in May-December, in parallel with trends in the general population and loosening of containment policy strength. Age > 40 years (p = 0.026), prednisone escalation (p = 0.008) and infected relatives (p < 0.001) were most significantly associated with COVID-19. Weaker associations were found with asthma, lymphadenopathy and azathioprine or cyclosporine treatment. Only 31% of patients with infected relatives developed COVID-19. Healthcare service disruptions were not associated with rising hospitalisations. Vaccination prospects were generally welcomed. Our data suggest that COVID-19 has a moderate impact on patients with SLE, which might be significantly modulated by public health policies, including vaccination.

Project description:To investigate the role of CD47 in inflammatory responses in systemic lupus erythematosus (SLE). Expression of CD47 and signal regulatory protein alpha (SIRPα) by peripheral blood mononuclear cells (PBMCs) and changes in CD47 expression after exposure to SLE serum, healthy control (HC) serum, recombinant interferon (IFN)-α, or tumor necrosis factor (TNF)-α were examined. Human monocytes and THP1 cells were incubated with lipopolysaccharide (LPS), an anti-CD47 antibody, or both. TNF-α production was examined. Sera from SLE patients and HCs were screened to detect autoantibodies specific for CD47. Twenty-five SLE patients and sixteen HCs were enrolled. CD47 expression by monocytes from SLE patients was higher than those from HCs (mean fluorescence intensity ± SD: 815.9 ± 269.4 vs. 511.5 ± 199.4, respectively; p < 0.001). CD47 expression by monocytes correlated with SLE disease activity (Spearman's rho = 0.467, p = 0.019). IFN-α but not TNF-α, increased CD47 expression. Exposing monocytes to an anti-CD47 antibody plus LPS increased TNF-α production by 21.0 ± 10.9-fold (compared with 7.3 ± 5.5-fold for LPS alone). Finally, levels of autoantibodies against CD47 were higher in SLE patients than in HCs (21.4 ± 7.1 ng/mL vs. 16.1 ± 3.1 ng/mL, respectively; p = 0.02). Anti-CD47 antibody levels did not correlate with disease activity (Spearman's rho = -0.11, p = 0.759) or CD47 expression on CD14 monocytes (Spearman's rho = 0.079, p = 0.838) in patients. CD47 expression by monocytes is upregulated in SLE and correlates with disease activity. CD47 contributes to augmented inflammatory responses in SLE. Targeting CD47 might be a novel treatment for SLE.

Project description:ObjectivePatients with systemic lupus erythematosus (SLE) are at higher risk of poor outcomes from coronavirus disease 2019 (COVID-19). The vaccination rate among such patients is unknown. We aimed to assess COVID-19 vaccine uptake among patients with SLE.MethodsWe included 342 patients with SLE from the Lupus Midwest Network (LUMEN) and 350 age-, sex-, race-, and county-matched comparators. Vaccination uptake for influenza, pneumococcal, and zoster vaccines before pandemic restrictions began (up to February 29, 2020) was assessed. First-dose COVID-19 vaccine uptake was electronically retrieved and manually ascertained (December 15, 2020, to July 31, 2021). Time to COVID-19 vaccination, demographics, SLE manifestations, medications, Charlson Comorbidity Index, Area Deprivation Index, and Rural-Urban Commuting Area codes were compared.ResultsOn July 31, 2021, 83.3% of patients with SLE and 85.5% of comparators were vaccinated against COVID-19. The COVID-19 vaccination rates were similar among SLE and comparators (hazard ratio 0.93, 95% CI 0.79-1.10). Unvaccinated patients with SLE were more likely than vaccinated patients to be men (27.3% vs 14.1%), younger (mean age 54.1 vs 58.8 yrs), have a shorter SLE duration (median 7.3 vs 10.7 yrs), and be less frequently vaccinated with influenza and pneumococcal vaccines.ConclusionPatients with SLE in the Lupus Midwest Network had similar COVID-19 vaccination uptake as matched comparators, most of whom were vaccinated early when the vaccine became available. One in 6 patients with SLE remain unvaccinated.

Project description:The SARS-CoV-2 novel coronavirus has caused the COVID-19 pandemic with over 35 million cases and over a million deaths worldwide as of early October 2020. The populations most affected are the elderly and especially those with underlying comorbidities. In terms of race and ethnicity, black and hispanic populations are affected at disproportionately higher rates. Individuals with underlying conditions that cause an immune-compromised state are considered vulnerable to this infection. The immune response is an important determinant in viral infections including coronaviruses, not only in the antiviral defense but also in the disease progression, severity, and clinical outcomes of COVID-19. Systemic lupus erythematosus is a chronic autoimmune disease which also disproportionately afflicts black and hispanic populations. In lupus patients, an aberrant immune response is characterized by the presence of circulating autoantibodies, lymphopenia, aberrant T cells, and proinflammatory cytokines along with defective regulatory mechanisms, leading to immune-mediated damage to tissues. Lupus patients are often treated with immune-suppressants and therefore are immune-compromised and more susceptible to infections and may be vulnerable to coronavirus infection. While the anti-viral immune response is important to protect from coronavirus infection, an uncontrolled proinflammatory cytokine response can lead to cytokine storm which causes damage to the lungs and other organs, causing significant morbidity and mortality. Better understanding of the underlying immune response and therapeutic strategies in lupus and COVID-19 is important to guide management of this deadly infectious disease in the context of lupus and vice-versa.

Project description:The severity of the coronavirus disease in 2019 (COVID-19) is strongly linked to a dysregulated immune response. This fuels the fear of severe disease in patients with autoimmune disorders continuously using immunosuppressive/immunomodulating medications. One complication of COVID-19 is thromboembolism caused by intravascular aggregates of neutrophil extracellular traps (NETs) occluding the affected vessels. Like COVID-19, systemic lupus erythematosus (SLE) is characterized by, amongst others, an increased risk of thromboembolism. An imbalance between NET formation and clearance is suggested to play a prominent role in exacerbating autoimmunity and disease severity. Serologic evidence of exposure to SARS-CoV-2 has a minor impact on the SLE course in a Swedish cohort reportedly. Herein, we assessed NET formation in patients from this cohort by neutrophil elastase (NE) activity and the presence of cell-free DNA, MPO-DNA, and NE-DNA complexes and correlated the findings to the clinical parameters. The presence of NE-DNA complexes and NE activity differed significantly in pre-pandemic versus pandemic serum samples. The latter correlated significantly with the hemoglobin concentration, blood cell counts, and complement protein 3 and 4 levels in the pre-pandemic but only with the leukocyte count and neutrophil levels in the pandemic serum samples. Taken together, our data suggest a change, especially in the NE activity independent of exposure to SARS-CoV-2.

Project description:COVID-19 vaccination has been shown to be safe in patients with systemic lupus erythematosus (SLE), but data on vaccine-associated adverse events (AEs) during the antenatal and lactation period are scarce or lacking. We investigated COVID-19 vaccination-related AEs in pregnant SLE patients from the COVAD study, a global esurvey involving 157 collaborators from 106 countries. A total of 9201 complete responses were extracted. Among 6787 (73.8%) women, we identified 70 (1.1%) who were exposed to at least one COVID-19 vaccine dose during pregnancy, 11 with SLE. Delayed onset (>7 days) vaccine-related AEs were triangulated with disease activity, treatment changes due to flare after vaccination, and COVID-19 infections in vaccinated pregnant women. Health-related quality of life and physical function was recorded using PROMIS. Age of patients ranged from 28 to 39 years; 5/11 women were of Asian origin. None of these patients reported major vaccine AEs or change in the status of their autoimmune disease. Although minor AEs were common, they did not impair daily functioning, and the symptoms resolved after a median of 3 (IQR: 2.5-5.0) days. All patients reported good to excellent health status. No adverse pregnancy outcomes were reported. Importantly, none of the patients reported thrombotic events post-vaccination, which provides reassurance in a patient population with a high risk for cardiovascular comorbidity and thrombosis, especially in the presence of antiphospholipid antibodies or the antiphospholipid syndrome, a considerable portion of SLE patients. Our findings provide reassurance and can contribute to informed decisions regarding vaccination in patients with SLE and highrisk pregnancies due to their background autoimmune disease. The risk/benefit ration of COVID-19 vaccination appears favourable, with vaccines both providing passive immunisation to the fetus and active immunisation to the mother with no signals of exacerbation of the mother's autoimmune disease.
