Can pregnancy lead to the worsening of lupus? HHS The risk of maternal morbidity is increased in the setting of active LN (11,23,44–47), including an increased risk of hypertensive disorders of pregnancy (42). Typically, renal biopsy is not advisable after 32 weeks of gestation. Although progressive renal impairment may occur, it is generally mild, and ESRD requiring hemodialysis is rare, even in patients with active LN (14). It is taken by mouth or injected into a vein. Systemic lupus erythematosus and pregnancy: the challenge of improving antenatal care and outcomes. Decisions regarding the timing and mode of delivery should be made in conjunction with an obstetrician with experience in managing labor in the setting of renal disease. eCollection 2019 Dec. Bray ER, Bray FN, Herskovitz I, Cho-Vega JH. Published online ahead of print. Clipboard, Search History, and several other advanced features are temporarily unavailable. A recent meta-analysis reported frequencies of 16.3% for hypertension and 7.6% for pre-eclampsia among pregnant LN patients. For most women with lupus, a successful pregnancy is possible. Azathioprine tablets should not be given during pregnancy without careful weighing of risk versus benefit. For example, mycophenolate mofetil and cyclophosphamide, frequently used for proliferative forms of LN, are contraindicated during pregnancy. Azathioprine is widely considered the safest immunosuppressant during pregnancy for women with lupus. Azathioprine is widely considered the safest immunosuppressant during pregnancy for women with lupus. Hormonal and immune system changes in pregnancy may affect disease activity and progression, and published evidence suggests that there is an increased risk for a LN flare during pregnancy. For the specific therapeutic and prophylactic anticoagulation regimens, therapeutic goals, and monitoring strategies, please refer to the American College of Chest Physicians evidence-based clinical practice guidelines on venous thromboembolism, thrombophilia, antithrombotic therapy, and pregnancy (65). Given the additional concerns related to the developing fetus, consideration must be given to the pregnancy-related safety and efficacy of the medications commonly used to manage LN (Table 2). Fecundity in SLE remains undiminished, save for the subgroups with antiphospholipid antibody syndrome (7) or advanced renal insufficiency (i.e., creatinine ≥3 mg/dl), or those women previously treated with cytotoxic alkylating agents. A retrospective cohort study of 476 women taking azathioprine early in pregnancy reported an increased risk of ventricular and atrial septal defects, as well as preterm birth . Consequently, current recommendations advise that the affected woman achieve a stable remission of her renal disease for at least 6 months before conception. The mainstay of management is anticoagulation (see Medical Management: Chronic Anticoagulation), which seems to improve both maternal and fetal outcomes. Lupus Nephritis (Off-label) Induction and maintenance therapy for lupus nephritis (2012 American College of Rheumatology guidelines) 2 mg/kg/day PO with or without low-dose corticosteroids . Results of a multidisciplinary approach, Outcome of pregnancy in patients with systemic lupus erythematosus. USA.gov. The GFR increases by 50% to 60%, with a subsequent increase in creatinine clearance of approximately 30%. Azathioprine is considered safer in pregnancy than other immunosuppressants, which typically have more severe side effects and a higher risk of effects on babies. The risk for progression is determined in part by the severity of the underlying renal disease and is increased for patients with creatinine values >1.4 mg/dl (33). She should initiate azathioprine, a well-known antirheumatic drug compatible with pregnancy and breastfeeding, titrated to a maximum of 2 mg/kg/day if needed to keep SLE with previous renal major involvement under control. Azathioprine: Azathioprine may be used cautiously in patients suffering from severe disease which has not responded to other medications during pregnancy. If the patient is breastfeeding, consideration should be given to the safety of immunosuppressive medications for the infant (Table 3). Azathioprine use in pregnancy has been studied predominantly in women with inflammatory bowel disease, and in those with prior renal transplantation. Reports of the effect of pregnancy on SLE activity are mixed, with some studies reporting a two- to three-fold increased risk of flare, whereas others indicate no increased risk (11,13–16). Azathioprine (AZA), although a category D medication, can be used if the benefits outweigh the risks. At 15 weeks of gestation, she experienced shortness of breath due to pulmonary embolism, with subsequent cardiorespiratory arrest. Int J Dermatol. In addition, membranous LN (class V) ideally would be treated with renin–angiotensin blockade, but these agents are contraindicated in pregnancy. doi: 10.1136/bmjopen-2017-020909. Antiphospholipid antibodies, including lupus anticoagulant and anticardiolipin antibodies, are autoantibodies that bind to cardiolipin and/or β2 glycoprotein-I bound to phospholipids. The random-effect rate of LN flare was estimated at 25.6% (17.4%–33.8%) (41). Underlying renal disease, in turn, places these pregnancies at higher risk for maternal and fetal complications, including spontaneous abortion, premature delivery, intrauterine growth retardation, and pre-eclampsia (35). Clinical remission of SLE activity and careful control of the disease are associated with improved outcomes, underlying the importance of careful monitoring of these patients throughout pregnancy (28–30). Complications of pregnancy after the onset of SLE included an increased risk of fetal death (29.7% versus 14.2%) and preterm birth (26.7% versus 5.8%). 6-MP is used to treat some cancers. Flares can occur at any gestational age, as well as in the postpartum period (17). Renal biopsy by electron microscopy of a 31-year-old woman with SLE for 10 years who presented at 6 weeks of gestation.
