Systemic lupus erythematosus and pregnancy: the challenge of improving antenatal care and outcomes.
The objective of this article is to describe maternal and perinatal outcomes in women with systemic lupus erythematosus (SLE) followed in a high-risk prenatal outpatient clinic at a referral center. ⋯ Despite the low percentages of women with pregestational and pregnancy-active disease, we found high incidences of maternal and perinatal complications. Preconception SLE activity increased gestational loss, and SLE activity during pregnancy increased prematurity. Effective immunosuppressive therapy was able to decrease clinical and laboratory activity of SLE; however, unfavorable perinatal outcomes still occurred, even when lupus activity was under control. Pregnancy in women with SLE is always a challenge.

Comparative Study Observational Study
Good survival rates in systemic lupus erythematosus in southern Sweden, while the mortality rate remains increased compared with the population.
To ascertain the mortality rate and causes of death in patients with systemic lupus erythematosus (SLE) within a defined region in southern Sweden during the time period 1981-2014 and determine whether these have changed over time. ⋯ In this long-term epidemiologic follow-up study of incident SLE, we report a substantially raised mortality rate amongst SLE patients compared with the general population. The mortality rates have not changed significantly during the observation period that spanned three decades. The main cause of death was cardiovascular disease and this finding was consistent over time.

The objective of this paper is to investigate the clinical features, outcomes, and risk factors for posterior reversible encephalopathy syndrome (PRES) in systemic lupus erythematosus (SLE). ⋯ PRES may be a reversible neurological deficit in patients with SLE other than neuropsychiatric lupus. Our results indicate two new risk factors for PRES and that PRES is associated with a higher mortality rate.

We determined the clinical utility of the direct Coombs' test in the absence of hemolytic anemia as an indicator of disease activity and therapeutic response in systemic lupus erythematosus (SLE). SLE patients without hemolytic anemia who visited our hospital from January 2016 to November 2016 were retrospectively evaluated with a direct Coombs' test. Clinical features, including SLE disease activity index (SLEDAI), treatment and laboratory findings were analyzed. ⋯ They had a higher SLEDAI ( p < 0.01), higher circulating immune complex levels ( p = 0.01), higher anti-DNA titers ( p < 0.01) and a lower complete renal response rate ( p = 0.03) compared with those who were negative. Multivariate analysis indicated that SLEDAI was an independent factor correlated with the direct Coombs' test without hemolytic anemia (odds ratio 2.4, 95% confidence interval 1.66-4.98, p < 0.01). A positive direct Coombs' test in the absence of hemolytic anemia may therefore represent a useful biomarker for assessing disease activity and therapeutic response.

Observational Study
Healthcare resource utilization and costs associated with long-term corticosteroid exposure in patients with systemic lupus erythematosus.
Objective To evaluate the association between exposure to oral corticosteroids and future healthcare resource utilization and costs for patients with systemic lupus erythematosus. Methods Adults diagnosed with systemic lupus erythematosus (index date) between 1 January 2008 and 30 June 2013 and naive to oral corticosteroids with continuous health plan enrollment for ≥6 months pre- and ≥5 years post-index were identified from a large health plan claims database. Per-patient monthly average daily dose of oral corticosteroids (prednisone or its equivalent) was calculated for the first 2 years post-index to categorize patients into four steroid exposure cohorts: low (≤5 mg/day), medium (6-20 mg/day), high (>20 mg/day) and no steroids. ⋯ A 1 mg increase in corticosteroid average daily dose was associated with 1.07 times the average annual costs after adjusting for baseline characteristics ( p < 0.0001). Conclusion Long-term high-dose oral corticosteroid use was associated with significantly greater future healthcare resource utilization and costs. Judicious reduction in daily steroid dose may decrease the imminent economic burden associated with high-dose steroid use in systemic lupus erythematosus.
