Lupus nephritis and pregnancy in the 21st century

Is lupus nephritis a prognosis factor for pregnancy? Maternal and foetal outcomes

BACKGROUND

Pregnancy in women with systemic lupus erythematosus (SLE) and nephritis (LN) is at risk of foetal and maternal complications.

OBJECTIVE

To evaluate the effect of LN on pregnancy with respect to foetal and maternal outcome.

METHODS

We retrospectively studied all pregnant SLE patients with and without diagnosis of LN, who attended the Materno Neonatal Hospital in Cordoba city, Argentina, from January 2015 to April 2017. Demographic, clinical, and laboratory data were collected. The presence of antiphospholipid syndrome (APS) and antiphospholipid antibodies (AAF), and maternal and foetal outcome were evaluated.

RESULTS

121 pregnancies in 79 patients were included. Pregnancies were divided into those with LN (69) and those without LN (52). The presence of APS and AAF was more frequent in the LN group as well as higher basal SLEDAI. The LN group received more immunosuppressive therapy and increased steroid dose treatment. Of the patients, 47.5% had Class IV LN. Lupus flares occurred more frequently in the LN group 25.8% vs 10.9% in the group without LN (P = .041), mainly renal flares in the LN group. No patients developed end-stage renal failure. Preeclampsia was more frequent in the LN group, 18.8% vs 6.3% in the group without LN (P = .047). There was only one maternal death. A caesarean section was required in 68.5% of the LN group vs 31.5 in the group without LN, and urgent caesarean section was also performed in the LN group. There were no differences in foetal outcomes in either group: live birth, gestational age, weight birth, perinatal death, foetal distress.

CONCLUSIONS

Patients with LN experienced more maternal complications such as lupus flares and preeclampsia. However, LN does not lead to a worse pregnancy and foetal outcome. Patients should be strictly monitored before and after conception.

Pregnancy in women with systemic lupus erythematosus (SLE)

For many years pregnancy has been contraindicated in patients with SLE, particularly when kidney involvement was present. Today, pregnancy is no longer considered impossible in women with lupus. Yet, lupus pregnancies are still considered high-risk. The prognosis has considerably improved for pregnant women but the fetal risk, although progressively reduced, is still higher in pregnancies of patients with SLE than in pregnancies of healthy women. Miscarriage, premature delivery, and preeclampsia, as well as heart problems in the baby are the major complications that can occur. In this paper we will review the outcome of pregnant women with SLE, the influence of lupus on fetal outcome, the effects of pregnancy on lupus, and the management of pregnant lupus patients based on our personal experience and the revision of the most recent and significant papers on the subject.

[Pregnancy in systemic autoimmune diseases: Myths, certainties and doubts]

Systemic autoimmune diseases especially affect young women during childbearing age. The aim of this review is to update systemic lupus erythematosus, antiphospholipid syndrome and systemic sclerosis management during pregnancy. These diseases present variable maternal and fetal risks. Studies show that an appropriate disease control and a reasonable remission period prior to pregnancy are associated with satisfactory obstetric outcomes. Antiphospholipid autoantibodies profile, anti-Ro/anti-La antibodies, pulmonary pressure and activity evaluation are crucial to assess the pregnancy risk. Monitoring requires a multidisciplinary team, serial analytic controls and Doppler ultrasound of maternal and fetal circulation. Evaluation of the activity of the disease is essential.

Systemic lupus erythematosus

Systemic lupus erythematosus is a remarkable and challenging disorder. Its diversity of clinical features is matched by the complexity of the factors (genetic, hormonal, and environmental) that cause it, and the array of autoantibodies with which it is associated. In this Seminar we reflect on changes in its classification criteria; consider aspects of its more serious clinical expression; and provide a brief review of its aetiopathogenesis, major complications, coping strategies, and conventional treatment. Increased understanding of the cells and molecules involved in the development of the diseases has encouraged the identification of new, better targeted biological approaches to its treatment. The precise role of these newer therapies remains to be established.

[Rheumatic diseases during pregnancy]

The treatment of inflammatory rheumatic diseases, such as rheumatoid arthritis, spondylitis ankylosans and systemic lupus erythematosus, is improving continuously. This has lead to an increasing number of young patients with a wish to have children. Greater insight into the course of rheumatic diseases during pregnancy and post partum has enabled optimized support for women with rheumatic diseases wishing to have children. To ensure a favorable outcome, pregnancy should be started during a period of disease stability and should be monitored closely. A careful assessment of possible risks and the justified use of antirheumatic drugs before, during and after pregnancy are key issues for success.

Maternal deaths in women with lupus nephritis: a review of published evidence

BACKGROUND AND OBJECTIVES

Pregnancies in women with systemic lupus erythematosus (SLE) and lupus nephritis are considered high-risk due to high rates of maternal and fetal complications. However, there has not been a formal analysis addressing the issue of maternal deaths in these women. The aim of this study was to perform a literature review of the maternal deaths in women with SLE and lupus nephritis to: (1) identify the main causes of death and (2) discuss possible reasons for these causes, and strategies that may improve patient care and outcomes. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENT: We performed an extensive electronic literature search from 1962 to 2009 using online databases (PubMed, Embase, Lilacs, Cochrane Controlled Trials Register, Medline, and Science Citation Index). Studies were included if they reported pregnancies in patients with SLE and lupus nephritis with at least one reported maternal death.

RESULTS

We identified 13 studies that reported a total of 17 deaths in the 6 week post-partum period that were attributable to SLE and lupus nephritis. In all cases, death occurred in the setting of active disease, and was attributed either to infection in 41.2% (n = 7), or disease activity in 29.4% (n = 5). The remaining deaths were due to pulmonary embolus in 11.8% (n = 2), pregnancy-associated cardiomyopathy in 5.9% (n = 1), adrenal failure due to abrupt steroid withdrawal in 5.9% (n = 1), and undefined in 5.9% (n = 1).

CONCLUSIONS

All maternal deaths in patients with SLE and lupus nephritis occurred in those with active disease, with disease activity/complications and infections (mainly opportunistic) being the two major causes. The presented evidence further supports timing of pregnancy relative to SLE activity, and the judicious use of immunosuppressive agents in pregnant patients.

[Management of pregnancy in patients with systemic lupus erythematosus]

Patients with systemic lupus erythematosus are exposed to a remarkably high number of maternal-fetal complications during pregnancy. Knowledge regarding the reciprocal influence between lupus and pregnancy is the starting point to assure that these patients are correctly monitored. It is also important to carry out comprehensive preconception evaluation to individually evaluate the risk of each patient. The immunological profile, history of nephritis, presence of chronic damage and disease activity are the basic data that will determine the specific individual risk profile. Finally, correct drug management must be assured during this period, based on the safety profile of the different treatments during pregnancy and lactation.

[Pregnancy and kidney diseases]

The prevalence of chronic kidney disease in women of childbearing age reaches approximately 0.2%. Under physiological conditions pregnancy results in important hemodynamic changes on the maternal organism. In the case of chronic kidney disease these adaptations often are only partial. Physiological changes of immune response during pregnancy may contribute to the progress of renal disease. Regardless of the underlying kidney disease, one can assume that the better the glomerular filtration rate and blood pressure are the more favorable the course of pregnancy will be with the chance for a healthy child and stable renal function. To achieve this goal, a close interaction is required between gynecologist, nephrologist, and other specialists in a center with appropriate experience.

Update on pregnancy in chronic kidney disease

The occurrence of pregnancy in patients with chronic kidney disease (CKD) has been considered a dangerous event both for the mother and for the fetus. However, increasing evidence shows that the stage of CKD is the leading factor that can predict possible acceleration in the declining of renal function and complications of pregnancy. This review summarizes recent data on pregnancy in patients with CKD, dialysis and kidney transplantation.

Lupus and pregnancy: integrating clues from the bench and bedside

Adequate pregnancy care of women with systemic lupus erythematosus (SLE) rests on three pillars: a coordinated medical-obstetrical care, an agreed and well-defined management protocol and a good neonatal unit. Pregnancy should be planned following a preconceptional visit for counselling. Women with severe active disease or a high degree of irreversible damage, such as those with symptomatic pulmonary hypertension, heart failure, severe restrictive pulmonary disease or severe chronic renal failure should best avoid pregnancy. Treatment is based on hydroxychloroquine, low-dose steroids and azathioprine. Patients with antiphospholipid antibodies/syndrome should receive low-dose aspirin +/- low molecular weight heparin. The addition and the dose of heparin depend on the clinical profile of the patient, i.e. a previous history of miscarriage, foetal loss, placental insufficiency or thrombosis. A close surveillance, with monitoring of blood pressure, proteinuria and placental blood flow by Doppler studies helps the early diagnosis and treatment of complications such as preeclampsia and foetal distress. Postpartum follow-up is important.
