Safety of Fertility Treatments in Women With Systemic Lupus Erythematosus: Data From a Prospective Population-Based Study.

Objective: To assess safety of fertility treatments in women with systemic lupus erythematosus (SLE).

Design: Data from the multicentre French observational GR2 (Groupe de Recherche sur la Grossesse et les Maladies Rares) study (2014-ongoing).

Setting: Seventy-six centres in France.

Hydroxychloroquine levels in pregnancy and materno-fetal outcomes in systemic lupus erythematosus patients.

Objectives: Data about hydroxychloroquine (HCQ) levels during pregnancy are sparse. We assessed HCQ whole-blood levels at first trimester of pregnancy as a potential predictor of maternal and obstetric/fetal outcomes in patients with systemic lupus erythematosus (SLE).

Methods: We included pregnant SLE patients enrolled in the prospective GR2 study receiving HCQ, with at least one available first-trimester whole-blood HCQ assay.

Polypharmacy, drug-drug interactions, and adverse drug reactions among systemic sclerosis patients: A cross-sectional risk factor study.

Objectives: Polypharmacy, drug-drug interactions (DDI) and related adverse drug reaction (ADR) are understudied in SSc. The aim of this work was to determine the prevalence and determinants of DDI and ADR in a real-life prospective cohort of SSc patients.

Methods: We performed a retrospective analysis of the drug prescriptions of SSc patients admitted to the daily scleroderma clinic between January 2020 and April 2022.

ANCA-associated scleritis: impact of ANCA on presentation, response to therapy and outcome.

Objectives: To describe the characteristics, treatment and outcome of isolated ANCA-associated scleritis at diagnosis compared with idiopathic scleritis with negative ANCA tests.

Methods: This retrospective multicentre case-control study was performed within the French Vasculitis Study Group (FVSG) network and in three French tertiary ophthalmologic centres. Data from patients with scleritis without any systemic manifestation and with positive ANCA results were compared with those of a control group of patients with idiopathic scleritis with negative ANCA tests.

Characterisation of a high-risk profile for maternal thrombotic and severe haemorrhagic complications in pregnant women with antiphospholipid syndrome in France (GR2): a multicentre, prospective, observational study.

Background: Prospective data about the risks of thrombotic and severe haemorrhagic complications during pregnancy and post partum are unavailable for women with antiphospholipid syndrome. We aimed to assess thrombotic and haemorrhagic events in a prospective cohort of pregnant women with antiphospholipid syndrome.

Methods: This multicentre, prospective, observational study was done at 76 centres in France.

Evaluation of the severe preeclampsia classification criterion for antiphospholipid syndrome in a study of 40 patients.

Background: The criteria for antiphospholipid syndrome (APS) include severe preeclampsia and/or placental insufficiency leading to preterm delivery before 34 weeks of gestation, but this APS manifestation has been rarely studied. Thus, we report a series of severe preeclampsia occurred in patients with APS.

Methods: We retrospectively analysed data of women with APS (Sydney criteria) who experienced severe preeclampsia with delivery before 34 weeks' gestation between 2000 and 2017 at five French internal medicine departments and one Italian rheumatology unit.
