Systemic vasculitis diagnosed during the post-partum period: case report and review of the literature.

INTRODUCTION: The vasculitis diagnosed specifically in the post-partum period are less well known. We report here such a case followed by a descriptive review of the literature. CASE REPORT: A 25 year-old French nurse reported abrupt-onset musculoskeletal pain 15 days after delivery of her first infant. Her first pregnancy was uneventful. The physical examination yielded only bilateral conjunctivitis and purpuric eruption of lower limbs, and complementary investigations evidenced pulmonary renal syndrome in connection with the diagnosis of Granulomatosis with Polyangiitis. METHODS: We screened previous articles in Medline database using keywords (i) "post-partum" or "puerperium" (ii)"peripartum" (iii) "pregnancy" associated with "vasculitis". Full texts were obtained from case reports or cases series whose title or abstract included keywords of interest (or synonyms). These references were secondarily excluded if the diagnosis of vasculitis was not confirmed or made before or more than 6 months after delivery and if vasculitis occurred only in the new born or affected only the cerebral vasculature or the retina. RESULTS: Fifty-six cases of vasculitis diagnosed in the post-partum period were included, 50 (89.3%) were secondary to an immunological process and 44 corresponded to primary vasculitis, 4 were secondary to Systemic Lupus Erythematosus, 1 to cryoglobulinaemia and 1 to cryoglobulinaemia associated with inflammatory bowel disease. The main primary vasculitis diagnosed were Takayasu Arteritis (n = 10), Eosinophilic granulomatosis with polyangiitis (n = 9), Granulomatosis with Polyangiitis (n = 7), Periarteritis Nodosa (n = 5) and Behcet's disease (n = 4). The first symptom occurred before delivery in 26 (59.1%) and maternal death occurred in 4 (9.1%) out of the 44 primary vasculitis cases. CONCLUSION: The vasculitis diagnosed in the post-partum period were mainly primary vasculitis among patients in whom the diagnosis had not been made during pregnancy. In less than half of cases and as described in ours, there were no reported symptoms before delivery. Therefore, the physicians should pay attention to symptoms and keep a high degree of suspicion for vasculitis before as well as after delivery.

Severe Libman-Sacks endocarditis complicating antiphospholipid syndrome: a retrospective analysis of 23 operated cases.

OBJECTIVE: Data on severe heart valve disease (HVD), including Libman-Sacks endocarditis, associated with SLE and/or APS requiring valvular surgery are scarce. We thus conducted a retrospective study, aimed at describing and clarifying clinical, laboratory, echocardiographic, histopathological and evolutional features of SLE and/or APS patients with severe associated-HVD. METHODS: An observational retrospective multicentric analysis of 23 adults with SLE and/or APS and HVD between 1996 and 2019 and available histopathological report evaluating long-term follow-up. RESULTS: Twenty-three individuals (20 females, median age 37 [range 17-76] years) were included. All had APS (thrombotic in 22, with an arterial phenotype in 15 and with catastrophic APS [CAPS] in six), and 11 (47%) had SLE. Systemic underlying disease had been diagnosed prior to HVD in 12 (52%). In 10 patients (43%), HVD was complicated by cerebral stroke prior to surgery. Twenty patients (87%) had only one pathological valve, the mitral valve in 18 patients (78%). Valvular thickening (n = 19) and valvular regurgitation (n = 19) were the most frequently reported lesions. Fifteen (62%) patients underwent mechanical valve replacement, six (26%) conservative valve repair (five were later re-operated after a median time of 1 [0-4] year), and two (9%) underwent biological valve replacement. Nine patients (39%) presented early-onset post-operative complications, including three CAPS immediately after surgery and one death. After surgery, 18 patients (78%) had normal postoperative valvular function, but almost half of the patients (43%) had post-operative neurological sequelae (median follow-up of 6 [2-20] years). CONCLUSION: Severe HVD leading to surgery was strongly associated with thrombotic APS, especially arterial phenotypes. Half of the reported patients presented cerebral stroke complicating the HVD. Valvular surgery carried a significant risk of CAPS.

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. To be eligible for this study, women had to have diagnosis of antiphospholipid syndrome; have conceived before April 17, 2020; have an ongoing pregnancy that had reached 12 weeks of gestation; and be included in the study before 18 weeks of gestation. Exclusion criteria were active systemic lupus erythematosus nephropathy, or a multifetal pregnancy. Severe haemorrhage was defined as the need for red blood cell transfusion or maternal intensive care unit admission because of bleeding or invasive procedures, defined as interventional radiology or surgery, to control bleeding. The GR2 study is registered with ClinicalTrials.gov, NCT02450396. FINDINGS: Between May 26, 2014, and April 17, 2020, 168 pregnancies in 27 centres met the inclusion criteria for the study. 89 (53%) of 168 women had a history of thrombosis. The median term at inclusion was 8 weeks gestation. 16 (10%) of 168 women (95%CI 5-15) had a thrombotic (six [4%] women; 95% CI 1-8) or severe haemorrhagic event (12 [7%] women; 95% CI 4-12). There were no deaths during the study. The main risk factors for thrombotic events were lupus anticoagulant positivity at inclusion (six [100%] of six women with thrombosis vs 78 [51%] of 152 of those with no thrombosis; p=0·030) and placental insufficiency (four [67%] of six women vs 28 [17%] of 162 women; p=0·013). The main risk factors for severe haemorrhagic events were pre-existing maternal hypertension (four [33%] of 12 women vs 11 [7%] of 156 women; p=0·014), lupus anticoagulant positivity at inclusion (12 [100%] of 12 women vs 72 [49%] of 146 women; p<0·0001) and during antiphospholipid history (12 [100%] of 12 women vs 104 [67%] of 156 women; p=0·019), triple antiphospholipid antibody positivity (eight [67%] of 12 women vs 36 [24%] of 147 women; p=0·0040), placental insufficiency (five [42%] of 12 women vs 27 [17%] of 156 women; p=0·038), and preterm delivery at 34 weeks or earlier (five [45%] of 11 women vs 12 [8%] of 145 women; p=0·0030). INTERPRETATION: Despite treatment adhering to international recommendations, a proportion of women with antiphospholipid syndrome developed a thrombotic or severe haemorrhagic complication related to pregnancy, most frequently in the post-partum period. Lupus anticoagulant and placental insufficiency were risk factors for these life-threatening complications. These complications are difficult to prevent, but knowledge of the antenatal characteristics associated with them should increase awareness and help physicians manage these high-risk pregnancies.
