OBJECTIVE: Systemic Lupus Erythematosus (SLE) is an autoimmune inflammatory disease. miR-155 and miR-146a were expressed in many autoimmune diseases such as rheumatoid arthritis. The aim of this study was to examine miR-155 rs767649 and miR-146a rs57095329 polymorphisms in SLE susceptibility in an Egyptian cohort and to investigate the correlation between them and clinical data and disease activity. PATIENTS AND METHODS: The two SNPs were analyzed in 120 patients with SLE and 100 healthy controls using RT-PCR...

OBJECTIVES: The randomized, double-blind, phase 2 b MUSE study evaluated the efficacy and safety of the type I interferon receptor antibody anifrolumab (300 mg or 1000 mg every 4 weeks) compared with placebo for 52 weeks in patients with chronic, moderate to severe SLE. Characterizing the exposure-response relationship of anifrolumab in MUSE will enable selection of its optimal dosage regimen in two phase 3 studies in patients with SLE. METHODS: The exposure-response relationship, pharmacokinetics (PK), and SLE Responder Index (SRI[4]) efficacy data were analysed using a population approach...

OBJECTIVE: We sought to explore patient and parental views on treatment targets, outcome measures and study designs being considered for a future juvenile-onset systemic lupus erythematosus (JSLE) treat to target (T2T) study. METHODS: Topic guided, semi-structured interviews with JSLE patients/parents. Analysis of audio recorded interviews using thematic approaches. RESULTS: Patients and parents differed regarding symptoms they felt would be tolerable, representing 'low disease activity'...

OBJECTIVES: During the COVID-19 pandemic, much communication occurred online, through social media. This study aimed to provide patient perspective data on how the COVID-19 pandemic impacted people with rheumatic and musculoskeletal diseases (RMDs), using Twitter-based patient-generated health data (PGHD). METHODS: A convenience sample of Twitter messages in English posted by people with RMDs was extracted between March 1, and July 12, 2020 and examined using thematic analysis...

OBJECTIVES: The long-term outcome of psychosis in association with Systemic Lupus Erythematosus (SLE) has been insufficiently characterised. We used a specialist centre cohort of patients with SLE and psychosis to investigate their clinical outcome and phenotypic and laboratory characteristics. METHODS: Retrospective cohort study of 709 SLE patients seen at a specialist centre between January 1978 and November 2018. Clinical, biochemical and immunological characteristics (Bonferroni corrected), and serum neuronal surface antibody profile using novel cell-based assays, were compared between patients with and without psychosis...

Long noncoding RNAs (lncRNAs) are persistently expressed and have been described as potential biomarkers and therapeutic targets in various diseases. However, there is limited information regarding lncRNA expression in the tissue of kidney exhibiting lupus nephritis (LN)a serious complication of systemic lupus erythematosus (SLE). In this study, RNA sequencing (RNA-seq) was performed to characterize the lncRNA and mRNA expression in kidney tissues from LN (MRL/lpr) and control mice. We identified 12,979 novel lncRNAs in mouse...

Drug-induced lupus is an iatrogenic-induced autoimmune disease with common offending agents well documented in the literature. To our knowledge, there are no prior case reports of drug-induced lupus associated with apixaban or any other direct oral anticoagulant. We describe a case of drug-induced lupus with leukocytoclastic vasculitis associated with apixaban started 15 days prior, after a WATCHMAN procedure for atrial fibrillation in an 86-year-old male previously anticoagulated on rivaroxaban.

Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disease, characterized by autoantibody production and immune complex formation, that has the potential to affect virtually any organ. Pleuropulmonary involvement occurs in 50-70% and commonly manifests as pleuritis and pleural effusion. Diffuse alveolar hemorrhage (DAH) is a rare manifestation of SLE. Most cases of DAH occur in young adults with an underlying autoimmune disease such as systemic vasculitis or Goodpasture syndrome. SLE is typically lower on the list of initial differential diagnoses of DAH due to its rarity compared to other etiologies...

We present the case of a 16-year-old female with systemic lupus erythematosus who presented with shock of unclear etiology, refractory to fluid resuscitation and triple vasopressors. She suffered pulseless electrical activity and underwent cannulation onto veno-arterial extracorporeal membrane oxygenation (ECMO). After cannulation, it was discovered she had intentionally overdosed on her home medication, amlodipine, a calcium channel blocker (CCB). She was supported on ECMO, treated with IV calcium and insulin, and was able to be weaned off ECMO after 4 days...

Background: Cryptococcus is an opportunistic fungal pathogen that leads to life-threatening infections. Cryptococcal infections are mainly reported in HIV patients and less commonly encountered in non-HIV immunocompromised host. Cryptococcus neoformans ( C. neoformans ) is the most common Cryptococcus species causing diseases in humans which can be presented as pulmonary, meningitis, cutaneous, and/or disseminated cryptococcosis. Case Presentation . A 12-year-old female girl from Cairo, Egypt, presented to the pediatric hospital with signs of systemic lupus erythematosus (SLE)...

Objectives: The present study aimed to observe the differences in creatinine clearance (Ccr) in systemic lupus erythematosus (SLE) patients with normal serum creatinine at different levels of urinary protein. Method: The present cross-sectional study included 177 SLE patients with normal serum creatinine from Qilu Hospital of Shandong University between January 2010 and April 2020. The following data were collected: blood urea nitrogen (BUN), serum creatinine (Cr), serum total protein, serum albumin, immunoglobulin (Ig) G, IgA, IgM, complement 3, complement 4, anti-ds-DNA antibody, routine urine test, urine protein/creatinine ratio (UPCR) (g/g), and the SLE disease activity index...

OBJECTIVE: To determine whether and how cognitive assessment data should be included in a report for patients with SLE and their providers. METHODS: Leveraging experiences from prior studies, we created a cognitive report that included a hypothetical patient's results on tests of multiple domains based on the NIH Toolbox Fluid Cognition Battery. In focus groups that comprised patients with SLE (two groups) and their providers (two groups), feedback was sought on the presentation of results as well as the potential value of the report in the clinical setting...

Systemic lupus erythematosus can affect any organ system at presentation and throughout its course. Lupus retinal vasculitis is responsible for visual loss of variable severity and typically ascribed to the involvement of pre-capillary superficial arterial vasculature. Using multimodal imaging techniques and electrophysiology, we demonstrate the first ever case of severe lupus retinal vasculitis resulting in the rare association of paracentral acute middle maculopathy. The findings showcase the involvement of both superficial and deep retinal capillary vasculature, and the localization of retinal dysfunction...

BACKGROUND: Prophylactic trimethoprim-sulfamethoxazole (TMP-SMX) prevents pneumocystis jirovecii infection in SLE on immunosuppression. Its role in preventing other major infections in immuno suppressed SLE patients is unknown. METHODS: A non-concurrent cohort study was conducted on patients of SLE fulfilling SLICC and/or ACR 1997 criteria, who received tapering dose of steroid starting with ≥0.5 mg/kg/day of prednisolone or equivalent dose of deflazacort and mycophenolate mofetil ≥1 g/day (or equivalent dose of mycophenolate sodium) at least for the preceding 1 year...

OBJECTIVE: To examine the impact of cumulative smoking in pack-years on systemic lupus erythematosus (SLE) cutaneous manifestations and damage. METHODS: Our cohort study included 632 adult SLE patients at an academic center, meeting 1997 ACR or 2012 SLICC classification criteria. Outcomes were: (1) cutaneous SLICC Damage Index (SDI), (2) ACR and SLICC criteria. Smoking exposure was defined as low (<5 pack-years), medium (5-10), and high (>10), compared to non-smokers...

OBJECTIVES: We aimed to identify transcriptional gene signatures predictive of clinical response, for pharmacodynamic evaluation, and to provide mechanistic insight into JNJ-55920839, a human IgG1κ neutralizing mAb targeting IFN-α/IFN-ω, in participants with systemic lupus erythematosus (SLE). METHODS: Blood samples were obtained from SLE participants at baseline and up to Day 130, who received six 10 mg/kg IV doses of JNJ-55920839/placebo every 2 weeks. Participants with mild-to-moderate SLE who achieved clinical responses using SLE Disease Activity Index 2000 Responder Index 4-point change were considered responders...

Systemic lupus erythematosus is a systemic autoimmune disease that affects the central nervous system, either by direct neuronal damage, injury to brain vessels, or by pathogenic mechanisms indirectly induced by immune mechanisms related to the production and deposition of immune complexes. The prevalence of explicit episodes of seizures among SLE patients, varies from 2 to 8%. In some cases, patients with positivity for antiphospholipid or anti-β2 glycoprotein antibodies are found to be more prone to exhibit seizures compared to seronegative patients, other subjects at risk are carries of gene abnormalities codifying for ion channels...

Three prime repair exonuclease 1 ( TREX1 ) degrades single- and double-stranded DNA with 3'-5' exonuclease activity. TREX1 mutations are related to type 1 interferon-mediated autoinflammation owing to accumulated intracellular nucleic acids. Several cases of systemic lupus erythematosus, Aicardi-Goutieres syndrome (AGS), familial chilblain lupus (FCL), and retinal vasculopathy-cerebral leukodystrophy caused by TREX1 mutations have been reported, so far. In this report, we described five patients with TREX1 mutations from three families with three different disorders, which include AGS, FCL, and FCL with central nervous system vasculitis...
