DNASE1L3 Deficiency With Novel Missense Variant: Enzymatic and Plasma Fragmentomic Evidence of Pathogenicity and Partial Response to JAK Blockade

open access: yesACR Open Rheumatology, Volume 8, Issue 2, February 2026.
Objective Biallelic loss‐of‐function variants in DNASE1L3 cause inherited systemic lupus erythematosus and hypocomplementemic urticarial vasculitis. These disorders arise from defective clearance of extracellular chromatin, leading to autoantibody formation, immune complex deposition, and complement consumption.

Antiphospholipid antibodies in Brazilian hepatitis C virus carriers

open access: yesBrazilian Journal of Medical and Biological Research, 2008
Hepatitis C, a worldwide viral infection, is an important health problem in Brazil. The virus causes chronic infection, provoking B lymphocyte dysfunction, as represented by cryoglobulinemia, non-organ-specific autoantibody production, and non-Hodgkin's ...

NARFL Knockout Triggers Ferroptosis‐Driven Vascular Endothelial Dysfunction

open access: yesAdvanced Science, Volume 13, Issue 8, 9 February 2026.
NARFL is vital for CIA and oxidative stress resistance. NARFL deletion in HPMEC cells, zebrafish, and mice is lethal and rescued by a Ferroptosis inhibitor. NARFL deficiency disrupted its interaction with CIA proteins, decreased aconitase activity, increased IRP1 activity, induced Fe overload, and led to ferroptosis and oxidative stress, resulting in ...

Estimation of Antiphospholipid Antibodies, Anticardiolipin Antibodies, Beta-2 Glycoprotein 1 Antibodies in Recurrent Pregnancy Loss - A Case-control Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2018
Introduction: Recurrent miscarriage is the occurrence of three or more consecutive pregnancy loss before 20 weeks of gestation. Antiphospholipid Antibodies (APAs) are one of the causes responsible for recurrent pregnancy loss.

Prognostic Value of Lupus Anticoagulant and Anti–β2 Glycoprotein I Antibody in Adverse Pregnancy Outcomes

open access: yesArthritis &Rheumatology, Volume 78, Issue 2, Page 371-384, February 2026.
Objective International criteria for antiphospholipid syndrome (APS) include lupus anticoagulant (LA), anticardiolipin (aCL) IgG and IgM, and anti–β2‐glycoprotein I (β2GPI) IgG and IgM. However, evidence supporting their prognostic value or treatment efficacy in improving live birth rates is limited.

Anticardiolipin antibodies in Jamaican primiparae

open access: yesJournal of Obstetrics and Gynaecology, 2006
A prevalence survey of anticardiolipin antibodies (aCL) was done among 924 primiparae. aCL were measured in serum by the standardised anticardiolipin enzyme linked immunosorbent assays (ELISA) and beta(2)-glycoprotein 1 assays to determine the seroprevalence of both beta(2) glycoprotein 1 dependent aCL and beta(2)-glycoprotein 1 independent aCL in ...

Deep capillary retinal ischemia and high-titer prothrombin-associated antiphospholipid antibodies: A case series of three patients

open access: yesAmerican Journal of Ophthalmology Case Reports, 2019
Purpose: Acute macular neuroretinopathy has been shown to be due to ischemia of the deep capillary retinal plexus and most cases occur in young women; we hypothesized that there may be an association with antiphospholipid antibodies.

POTS and Antiphospholipid Syndrome: An Unlikely Association

open access: yesCase Reports in Rheumatology, 2021
Antiphospholipid syndrome is a rare complication of postural orthostatic tachycardia syndrome. Clinically, the presentation has overlapping symptoms of both diseases, with lightheadedness or syncope when moving from a supine to a standing position as ...

Laboratory Identification of Lupus Anticoagulant (LA) Using Different Activated Partial Thromboplastin Time (APTT) Assays

open access: yesInternational Journal of Laboratory Hematology, Volume 48, Issue 1, Page 172-178, February 2026.
ABSTRACT Introduction The International Society of Thrombosis and Hemostasis (ISTH) guidelines suggest a three‐step evaluation for the detection of lupus anticoagulant (LA), including screening, mixing, and confirmation. According to the guidelines, the LA assay based on activated partial thromboplastin time (APTT) should include an initial screening ...

Facts and Misfacts on D‐Dimer Testing. Consensus Guidance From the Italian Society on Thrombosis and Hemostasis (SISET)

open access: yesAmerican Journal of Hematology, Volume 101, Issue 1, Page 97-109, January 2026.
ABSTRACT D‐dimer defines degradation products derived from the proteolysis mediated by plasmin on cross‐linked fibrin. The evidence‐based use of D‐dimer in some conditions has been consolidated. Currently, however, there is an entrenched prescription of D‐dimer testing to screen otherwise healthy subjects that may induce prescribing physicians to start
