This study aims to investigate the fetal outcomes and associated factors of adverse pregnancy outcomes (APOs) in pregnant women with systemic lupus erythematosus (SLE). Clinical data from 251 SLE patients with 263 pregnancies from 2001 to 2015 were analyzed retrospectively. APOs occurred in 70.0% of pregnancies, in which pregnancy loss occurred in 28.5%; preterm delivery occurred in 21.3%; intrauterine growth retardation occurred in 12.2%; and fetal distress occurred in 8.0%. Over time, the rate of APOs decreased from 82...

An adolescent girl, a known case of spina bifida with systemic lupus, presented with bluish discolouration of three toes of the right foot. She had thrombosis of bilateral popliteal arteries. She underwent percutaneous transluminal angioplasty (PTA) of both legs and Chopart amputation of the right foot. Systemic lupus erythematosus (SLE) occurring in a patient with spina bifida has not been previously reported. Weakness, sensory loss, lack of normal ambulation, endarteritis, antiphospholipid antibody syndrome are common contributory factors for peripheral gangrene in patients with spina bifida with systemic lupus erythematosus...

Antiphospholipid antibody syndrome (APS) is an enigmatic heterogeneous disorder despite several revelations in its pathobiology. Renal transplantation in patients with APS has been notoriously difficult due to the high risk of development of thrombotic microangiopathy (TMA), which is often refractory to conventional treatment modalities such as aggressive anticoagulation and plasmapheresis. We describe a case of a 58-year-old male with secondary APS undergoing living unrelated renal transplantation for end-stage renal disease from lupus nephritis...

Antiphospholipid syndrome (APS) is the most important treatable cause of recurrent pregnancy loss. The live birth rate is limited to only 70-80% in patients with APS undergoing established anticoagulant therapy. Lupus anticoagulant (LA), but not anticardiolipin antibody (aCL), was found to predict adverse pregnancy outcome. Recent genome-wide association studies (GWAS) of APS focusing on aCL have shown that several molecules may be involved. This is the first GWAS for obstetric APS focusing on LA. A GWAS was performed to compare 115 Japanese patients with obstetric APS, diagnosed according to criteria of the International Congress on APS, and 419 healthy individuals...

OBJECTIVES: The CD40L/CD40 pathway is involved in the pathophysiology of atherothrombotic disease, and elevated levels of soluble CD40L (sCD40L) were reported in SLE patients. However, the clinical implication of sCD40L in SLE remains elusive. METHODS: We measured levels of plasma sCD40L in 241 SLE patients and 37 healthy controls and investigated its association with clinical manifestation and laboratory parameters. RESULTS: Levels of plasma sCD40L in SLE patients were significantly elevated compared with healthy controls (p=0...

Etiologic factors for recurrent miscarriage (RM) include autoimmune diseases, the most frequently antiphospholipid syndrome and thyroiditis. Some women who suffer from RM might also have an altered immune system. We aimed to evaluate possible associations between anti-thyroid and anti-phospholipid antibodies in women with RM. In a retrospective case series 1 on 156 women with RM, major outcome parameters were antibodies against cardiolipin, β2-glycoprotein I, thyreoperoxidase (TPO-Ab), and thyroglobulin (TG-Ab)...

BACKGROUND: Pulmonary hypertension (PH) is a life-threatening condition that may affect outcomes in patients with systemic lupus erythematosus (SLE). The role of antiphospholipid antibodies (aPL) on the risk of PH is controversial. Therefore our objective was to estimate the risk of PH (WHO groups 1-5) including associated pulmonary arterial hypertension (APAH, WHO group 1 only) related to aPL in patients with SLE. METHODS: Systematic review and meta-analysis were performed: MEDLINE, EMBASE, Cochrane Library, congress abstracts, and reference lists of eligible studies were searched through 2015...

IgA anti-β2glycoprotein I antibodies (IgA-anti-β2GPI) seems to be the most prevalent isotype in patients with Systemic Lupus Erythematosus (SLE) with a significant association to thrombotic events. Both SLE and antiphospholipid syndrome (APS) can be associated with implantation failure, fetal loss and obstetric complications. Recent reports highlight the clinical value of IgA-anti-β2GPI determination in supporting in vitro fertilization (IVF) treatment and IVF pregnancy outcomes. We report a 36-year-old female diagnosed with SLE, endometriosis and unexplained infertility...

BACKGROUND AND OBJECTIVES: Kidney disease is a critical concern in counseling patients with lupus considering pregnancy. This study sought to assess the risk of renal flares during pregnancy in women with previous lupus nephritis in partial or complete remission, particularly in those with antidouble-stranded DNA antibodies and low complement levels, and the risk of new-onset nephritis in patients with stable/mildly active SLE. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We assessed active nephritis (renal flares and de novo kidney disease) and associated predictors during pregnancy in patients with lupus with urine protein ≤1000 mg and serum creatinine <1...

Antiphospholipid syndrome (APS) is an autoimmune condition characterized by a thrombotic event and/or pregnancy morbidity in the presence of persistently elevated antiphospholipid (aPL) antibody titers, which are most prevalent in patients with systemic lupus erythematosus but also have been associated with other autoimmune, malignant, and infectious diseases. In contrast to the clear correlation between high aPL antibody titers and thrombotic events in patients with systemic lupus erythematosus, the pathogenic role of these autoantibodies in association with other diseases, such as rheumatoid arthritis (RA), is not as well defined...

Neuropsychiatric symptoms occur commonly in patients with systemic lupus erythematosus, but they are not always due to active disease. It is crucial to identify cases that are due to active systemic lupus erythematosus so that appropriate treatment can be instituted. There is no single serological or imaging test that distinguishes active neuropsychiatric systemic lupus erythematosus from neuropsychiatric manifestations caused by other factors such as infection. Most patients with neuropsychiatric systemic lupus erythematosus have generalised features of disease activity...

Background Systemic lupus erythematosus (SLE) and antiphospholipid antibody syndrome (APS) are autoimmune diseases that affect women of childbearing age. Maternal IgG antiphospholipid antibodies (aPL) can cross the placenta during pregnancy and theoretically reach the fetal brain. Some studies showed an increased number of learning disabilities in these children. Objectives To evaluate the long-term neurodevelopmental outcome of 40 children (median age 7.4 years) born to mothers with SLE and/or APS carrying positive IgG aPL during the third trimester of pregnancy...

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can affect different ocular structures, such as cornea, conjunctiva, episclera, sclera, uveal tract, retina, optic nerve and vessels. Neuro-ophthalmologic manifestations in SLE include different degrees of involvement of retina, choroid and optic nerve. Retinal changes are one of the most common ocular involvements and are frequently used as clinical criteria for activity, even if isolated. Studies show that up to 29% of patients with active SLE manifest retinal disease...

BACKGROUND: Annexin A5 (A5) is a potent anticoagulant protein that shields anionic phospholipids from availability for coagulation reactions. Previous studies showed that antibodies from patients with antiphospholipid (aPL) syndrome (APS) interfere with A5 crystallization and anticoagulant activity. OBJECTIVE: The purpose of this study was to investigate whether reduction of the Annexin A5 Anticoagulant Ratio (A5R) assay (i.e. "A5 resistance") is associated with adverse clinical events in aPL antibody-positive patients...

Inferior vena cava (IVC) filters are useful adjuncts to prevent venous thromboembolism to the pulmonary circulation in the setting of contraindication for anticoagulation. Despite their proven decreased rate of pulmonary embolism, IVC filters are not without complications. We herein present the case of a 22-year-old man with a history of antiphospholipid antibody syndrome who was sent to our institution for evaluation with Budd-Chiari and post-thrombotic syndromes associated to a chronic retrohepatic complete IVC occlusion secondary to an IVC filter placed 5 years earlier...

PURPOSE OF REVIEW: It is well established that the antiphospholipid syndrome (APS) is caused by antiphospholipid antibodies (aPL). While several underlying mechanisms have been described in the past, many open questions remain. Here, we will review data on endosomal signaling and, in particular, redox signaling in APS. RECENT FINDINGS: Endosomal redox signaling has been implicated in several cellular processes including signaling of proinflammatory cytokines. We have shown that certain aPL can activate endosomal NADPH-oxidase (NOX) in several cell types followed by induction of proinflammatory and procoagulant cellular responses in vitro...
