Infection is a major cause of morbidity and mortality among patients with systemic lupus erythematosus (SLE). To describe the pattern of serious infections in patients with SLE and to identify the predictors of infection-related mortality among SLE patients with serious infections, we prospectively studied all SLE patients who were hospitalized with infections in Sarawak General Hospital during 2011-2015. Demographic data, clinical features, and outcomes were collected. Cox regression analysis was carried out to determine the independent predictors of infection-related mortality...

Background Severe brady-arrhythmias, requiring a permanent pacemaker (PPM), have been sparsely reported in systemic lupus erythematosus (SLE). The aim of this study was to describe the characteristics of such arrhythmias in a defined lupus cohort. Patients and methods The database of the Toronto Lupus Clinic ( n = 1366) was searched for patients who received a PPM. Demographic, clinical, immunological and therapeutic variables along with electrocardiographic (ECG) and echocardiographic findings (based on the last available test prior to PPM) were analyzed...

Objective We estimated the incremental (extra) direct medical costs of a population-based cohort of newly diagnosed systemic lupus erythematosus (SLE) for five years before and after diagnosis, and the impact of sex and socioeconomic status (SES) on pre-index costs for SLE. Methods We identified all adults newly diagnosed with SLE over 2001-2010 in British Columbia, Canada, and obtained a sample of non-SLE individuals from the general population, matched on sex, age, and calendar-year of study entry. We captured costs for all outpatient encounters, hospitalisations, and dispensed medications each year...

There are varying observations on the influence of ethnicity on the clinical spectrum and response to treatment in lupus nephritis (LN). We studied a multiethnic South African LN cohort to determine the clinical manifestations, histological involvement and response to therapy. We reviewed the records of LN patients at Inkosi Albert Luthuli Central Hospital in Durban. There were 105 patients, 92.5% females and they comprised 49.1% Indians and 45.3% African Blacks. The mean age was 31.3 ± 12.5 years, and 41...

BACKGROUND: Most cases of chronic urticaria (CU) are idiopathic. Circumstantial evidence suggests that some CU cases have an autoimmune pathogenesis. Previous research indicates that a substantial percentage of patients with CU have an atopic background. OBJECTIVES: This study aims to examine the association between CU, and atopic and autoimmune diseases. METHODS: This population-based retrospective cohort study identified 9,332 patients with CU and 37,328 controls matched for age, sex, and number of dermatological clinic visits from the Taiwan National Health Insurance Research Database for 2004-2009...

Systemic lupus erythematosus (SLE) patients are associated with insulin resistance and are at higher risk to develop diabetes mellitus (DM). SLE and DM could lead to renal failure respectively. However, it is unknown whether DM increases the risk of end-stage renal disease (ESRD) in SLE patients. This study aimed to evaluate potential synergistic effect of DM on SLE patients for development of ESRD. We conducted this study by using National Health Insurance Research Database of Taiwan. We recruited SLE patients with newly-diagnosed DM as the study cohort...

OBJECTIVE: In a longitudinal cohort study, we investigated whether clinical and serological manifestations at the time of classification of systemic lupus erythematosus (SLE) were predictive of subsequent development of incident proteinuria as a biomarker of incident lupus nephritis. METHODS: Patients fulfilling SLE classification criteria but having no proteinuria prior to or at the time of classification were included. Data on SLE manifestations, vital status, criteria-related autoantibodies, and SLE-associated medications were collected during clinical visits and supplemented by chart review...

OBJECTIVE: Cardiovascular disease (CVD) risks among patients with systemic lupus erythematosus (SLE) are similar to those in diabetes mellitus (DM). We investigated whether patients with SLE receive lipid testing and statin prescriptions comparably to DM patients and to individuals without either disease. METHODS: We identified U.S. Medicaid beneficiaries ages 18-65, residing in 29 states from 2007-2010 with prevalent SLE. Each SLE patient was age- and sex-matched to two DM, and four general Medicaid recipients without either disease...

Measurement of type I interferon (IFN-I) has potential to diagnose and stratify autoimmune diseases, but existing results have been inconsistent. Interferon-stimulated-gene (ISG) based methods may be affected by the modularity of the ISG transcriptome, cell-specific expression, response to IFN-subtypes and bimodality of expression. We developed and clinically validated a 2-score system (IFN-Score-A and -B) using Factor Analysis of 31 ISGs measured by TaqMan selected from 3-IFN-annotated modules. We evaluated these scores using in-vitro IFN stimulation as well as in sorted cells then clinically validated in a cohort of 328 autoimmune disease patients and healthy controls...

OBJECTIVES: Systemic lupus erythematosus (SLE) is a prototype autoimmune disease with a strong genetic component in its pathogenesis. Through genome-wide association studies (GWAS), we recently identified 10 novel loci associated with SLE and uncovered a number of suggestive loci requiring further validation. This study aimed to validate those loci in independent cohorts and evaluate the role of SLE genetics in drug repositioning. METHODS: We conducted GWAS and replication studies involving 12 280 SLE cases and 18 828 controls, and performed fine-mapping analyses to identify likely causal variants within the newly identified loci...

REVIEW
Hannah Cohen, Maria Efthymiou, David Isenberg
The direct oral anticoagulants (DOACs) are therapeutic alternatives to warfarin and other vitamin K antagonists (VKAs), and the standard of care for many indications. VKAs are conventional therapy for the treatment and secondary thromboprophylaxis of thrombotic antiphospholipid syndrome (APS), but are often problematic due to the variable sensitivity of thromboplastins to lupus anticoagulant. Thus, the International Normalised Ratio may not accurately reflect anticoagulation intensity, or be clinically effective...

Objectives: Increased release of neutrophil extracellular traps (NETs) is implicated in the activation of plasmacytoid dendritic cells, vascular disease and thrombosis in SLE and APS. However, studies comparing NET release between patients with SLE and APS are lacking. Here we evaluated plasma-induced NET release in a large cohort of patients with SLE, SLE + APS and primary APS in relation to clinical and serological parameters. Methods: Neutrophils from healthy controls were exposed to plasma of heterologous healthy controls (n = 27) or SLE (n = 55), SLE + APS (n = 38) or primary APS (PAPS) (n = 28) patients and NET release was quantified by immunofluorescence...

OBJECTIVES: In 2004 and 1999, respectively, recent-onset rheumatoid arthritis (RA) and systemic lupus erythematous (SLE) cohorts were initiated; the 36 item Medical Outcome Study Short-Form survey (SF-36) was applied beginning from enrolment. The objectives were to compare the SF-36v2 scores between patients from both cohorts who achieved sustained remission and to define the role of disease diagnosis as associated to SF-36v2 normative data in remission patients. METHODS: Sustained remission was considered when RA and SLE patients achieved at least 12 months of continuous follow-up with either SLE disease activity index 2000 update =0 or Disease Activity Score (28 joints) ≤2...

A hallmark of systemic lupus erythematosus (SLE) is the breaking of B-cell tolerance with the generation of high-affinity autoantibodies; however, the antibody-independent features of the B-cell compartment in SLE are less understood. In this study, we performed an extensive examination of B-cell subsets and their proinflammatory properties in a Chinese cohort of new-onset SLE patients. We observed that SLE patients exhibited an increased frequency of transitional B cells compared with healthy donors and rheumatoid arthritis patients...

Objective: B cell depletion, most commonly with rituximab, is an evolving therapeutic approach in SLE. Infusion reactions after rituximab are common, and may prevent re-treatment in patients who previously demonstrated beneficial response. We have used ofatumumab, a fully humanized anti-CD20 mAb, as an alternative B cell-depleting agent in patients with SLE who are rituximab-intolerant due to severe infusion reactions. Methods: A single-centre retrospective case series of 16 patients were treated with ofatumumab for SLE between 2012 and 2015...
