Article Synopsis
  • The study aimed to identify factors that affect the disease activity of systemic lupus erythematosus (SLE) in women during a two-year postpartum follow-up, with regular assessments every three months.
  • It involved 119 women as participants and found that joint pain, skin issues, and blood problems were common, with 51.3% experiencing disease flares within about 9 months after giving birth.
  • The findings suggest that achieving remission before conception can lead to better outcomes for SLE patients, emphasizing the importance of counseling for planned pregnancies in these individuals.

Objectives: To describe the outcomes of pregnancies in antiphospholipid antibody (aPL)-positive patients since the inception of the AntiPhospholipid Syndrome Alliance for Clinical Trials and InternatiOnal Networking Registry.

Methods: We identified persistently aPL-positive patients recorded as 'pregnant' during prospective follow-up, and defined as a composite of: (1) Preterm live delivery (PTLD) at or before 37th week due to pre-eclampsia (PEC), eclampsia, small-for-gestational age (SGA) and/or placental insufficiency (PI); or (2) Otherwise unexplained fetal death after the 10th week of gestation. The primary objective was to describe the characteristics of patients with and without aPL-related composite outcomes based on their first observed pregnancies following registry recruitment.

Article Synopsis
  • - The study aims to improve the classification and treatment of systemic autoimmune diseases by identifying molecular clusters, moving beyond traditional clinical diagnosis methods.
  • - Researchers analyzed blood samples from 955 patients and 267 healthy controls, discovering four distinct clusters: three linked to inflammatory responses and one related to low disease activity associated with healthy controls.
  • - The findings suggest that these molecular clusters are stable over time and can aid in understanding disease mechanisms and improving treatment strategies, potentially changing how systemic autoimmune diseases are approached in clinical settings.

Objective: To describe the baseline characteristics of patients with positivity for antiphospholipid antibodies (aPLs) who were enrolled in an international registry, the Antiphospholipid Syndrome (APS) Alliance for Clinical Trials and International Networking (APS ACTION) clinical database and repository, overall and by clinical and laboratory subtypes.

Methods: The APS ACTION registry includes adults who persistently had positivity for aPLs. We evaluated baseline sociodemographic and aPL-related (APS classification criteria and "non-criteria") characteristics of patients overall and in subgroups (aPL-positive without APS, APS overall, thrombotic APS only, obstetric APS only, and both thrombotic APS/obstetric APS).

Objective: This study aimed to use cluster analysis (CA) to identify different clinical phenotypes among antiphospholipid antibodies (aPL)-positive patients.

Methods: The Alliance for Clinical Trials and International Networking (APS ACTION) Registry includes persistently positive aPL of any isotype based on the Sydney antiphospholipid syndrome (APS) classification criteria. We performed CA on the baseline characteristics collected retrospectively at the time of the registry entry of the first 500 patients included in the registry.

Objective:  This article aims to analyse the rate of antiphospholipid antibodies (aPL) negativisation in patients with antiphospholipid syndrome (APS), and to evaluate potential new clinical manifestations after negativisation and/or aPL fluctuations in a long-term follow-up.

Methods:  Inclusion criteria are (1) any patients with an APS diagnosis according to the current Sydney criteria and (2) patients in whom aPL negativisation occurred. aPL negativisation was defined as repeated aPL measurements on at least two consecutive occasions at least 12 weeks apart, with a follow-up of at least 1 year since aPL first turned negative.

Background: Systemic lupus erythematosus (SLE) is a genetically complex rheumatic disease characterized by heterogeneous clinical manifestations of unknown etiology. Recent studies have suggested the existence of a genetic basis for SLE heterogeneity. The objective of the present study was to identify new genetic variation associated with the clinically relevant phenotypes in SLE.

Objective: To provide a reference to rheumatologists and other physicians involved in the treatment of systemic lupus erythematosus (SLE) who are using, or about to use biologic therapies.

Methods: Recommendations were developed following a nominal group methodology and based on systematic reviews. The level of evidence and degree of recommendation were classified according to a model proposed by the Center for Evidence Based Medicine at Oxford.
