Previous reports suggest that renal involvement before pregnancy or active renal disease during pregnancy may be associated with poor fetal and maternal outcomes in systemic lupus erythematosus (SLE) women. We report our experience of fetal and maternal complications in pregnant lupus women with and without previous lupus nephritis. We analyzed the clinical records of pregnant SLE patients attended in a tertiary reference center during a 5-year period. Patients were allocated into two groups according to the presence or absence of previous lupus nephritis. Women were evaluated monthly during pregnancy and at least 1 month postpartum. Maternal and fetal outcomes of pregnancy were abstracted. We included 95 pregnancies in 92 patients. Compared with pregnant women without lupus nephritis (n = 60), pregnancies with previous lupus nephritis (n = 35) were associated with a higher risk of maternal complications (88.5% vs. 43.3%, p = 0.00001), higher rate of lupus flares (54.2% vs. 25%, p = 0.004), and renal flares (45.7% vs. 6.6%, p = 0.00001), but most of which in most instances were reversible. On the other hand, fetal outcome was similar in both groups. Multivariate analysis showed that previous lupus nephritis and active lupus at conception were predictors of adverse maternal outcome. Pregnancies in women with previous lupus nephritis had a higher rate of maternal complications in comparison with those without. However, fetal prognosis was similar in both groups.
Introduction: Several factors have been associated with the development of preeclampsia in women with systemic lupus erythematosus (SLE). Objective:To identify risk factors associated with preeclampsia in patients with SLE and its impact on fetal outcomes. Patients and methods:We studied a prospective cohort of pregnancies in women with SLE from January 2009 to December 2018. Demographic, clinical, serological and drug use characteristics were compared between patients who developed preeclampsia and those who did not, as well as the main neonatal outcomes. An adjusted logistic regression analysis was performed to identify factors potentially associated with preeclampsia. Results:We studied 316 pregnancies of 20 or more weeks of gestation. A total of 46 pregnancies (14.5%) were complicated by preeclampsia. A higher frequency of active disease before pregnancy (24.4% vs 11.3%, P = .01) and history of lupus nephritis (56.5% vs 30.1%, P < .001) were found in those patients who developed preeclampsia compared to those who did not. Preeclampsia was associated with a higher rate of prematurity, births of very low birth weight, stillbirth, and neonatal death. The multivariate analysis showed that the activity of the disease before (relative risk [RR] 2.7, 95% CI 1.04-7.4, P = .04) and during pregnancy (RR 3.0, 95% CI 1.0-9.1, P = .04) was associated with the development of preeclampsia. The use of antimalarial drugs during pregnancy was associated with a lower risk of preeclampsia (RR 0.21, 95% CI 0.08-0.53, P < .001). Conclusions:Our study suggests that the use of antimalarial drugs during pregnancy reduces the risk of preeclampsia in lupus pregnancies.

The aim of this study was to estimate the impact of the haematological manifestations of systemic lupus erythematosus (SLE) on mortality in hospitalized patients. For that purpose a case-control study of hospitalized patients in a medical referral centre from January 2009 to December 2014 was performed. For analysis, patients hospitalized for any haematological activity of SLE ( n = 103) were compared with patients hospitalized for other manifestations of SLE activity or complications of treatment ( n = 206). Taking as a variable outcome hospital death, an analysis of potential associated factors was performed. The most common haematological manifestation was thrombocytopenia (63.1%), followed by haemolytic anaemia (30%) and neutropenia (25.2%). In the group of haematological manifestations, 17 (16.5%) deaths were observed compared to 10 (4.8%) deaths in the control group ( P < 0.001). The causes of death were similar in both groups. In the analysis of the variables, it was found that only haematological manifestations were associated with intra-hospital death (odds ratio 3.87, 95% confidence interval 1.8-88, P < 0.001). Our study suggests that apparently any manifestation of haematological activity of SLE is associated with poor prognosis and contributes to increased hospital mortality.
