azathioprine pregnancy lupus

However, recent studies report its safe usage as part of the management of breast cancer, during the second and third trimesters of pregnancy, without any significant fetal complications (85). Given the increased maternal and fetal risks associated with lupus nephritis (LN), the clinician should be familiar with the pertinent issues related to its management before and during pregnancy. The objective of this study was to evaluate the risk of adverse fetal outcome in systemic lupus erythematosus (SLE) women exposed to azathioprine during pregnancy. Obstetric Nephrology: Lupus and Lupus Nephritis in Pregnancy, Kidney Outcomes and Risk Factors for Nephritis (Flare/De Novo) in a Multiethnic Cohort of Pregnant Patients with Lupus, HELLP syndrome: a diagnostic conundrum with severe complications, Podocyturia Predates Proteinuria and Clinical Features of Preeclampsia: Longitudinal Prospective Study, DOI: https://doi.org/10.2215/CJN.12441211, Lupus erythematosus simulating toxemia of pregnancy, Disseminated lupus erythematosus in pregnancy, Pregnancy and systemic lupus erythematosus: Review of clinical features and outcome of 51 pregnancies at a single institution, Obstetrical outcome of pregnancy in patients with systemic lupus erythematosus. Measurable SLE disease activity is present in 40%–50% of pregnancies, with the most common manifestations being cutaneous disease (25%–90%), LN (up to 75%), arthritis (20%), and hematologic disease, including thrombocytopenia (10%–40%). These data have been corroborated by numerous other studies (19,21–25). This review discusses the pathogenesis, maternal and fetal risks, and management pertinent to SLE patients with new onset or a history of LN predating pregnancy. 1 mg/kg/day IV/PO initially in single daily dose or divided q12hr; after 6-8 weeks, increase by 0.5 mg/kg/day every 4 weeks; not to exceed 2.5 mg/kg/day. Hormonal and immunologic changes in pregnancy seem to affect the activity of SLE in general, and LN in particular. Serum creatinine in a pregnant woman is lower than in a nonpregnant woman, and varies by trimester. Renal biopsy data should be incorporated into the counseling session (32). Because data regarding its safety in pregnancy are lacking, rituximab should be avoided until its safety and efficacy have been demonstrated. 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). Having been in a wheelchair, just over six stone, in constant severe pain and desperately weak, I really had no option. Several studies have shown Azathioprine to improve disease activity in severe lupus nephritis. 1997 Sep;40(9):1725 As you know, each person’s experience with lupus is unique. In all patients, death occurred in the setting of active renal disease, with infection and SLE complications being the two most common causes, accounting for 41.2% and 29.4% of all deaths, respectively. For example, the number of Tregs is diminished in pre-eclamptic relative to normotensive pregnancies (9). Progesterone-induced smooth muscle relaxation and compression of the ureters by the enlarging uterus can result in a physiologic hydronephrosis, predisposing the pregnant woman to pyelonephritis and symptomatic urolithiasis. Azathioprine, sold under the brand name Imuran, among others, is an immunosuppressive medication. For most women with lupus, a successful pregnancy is possible. Flow diagram of the management of lupus nephritis in pregnancy. doi: 10.1136/bmjopen-2017-020909. NIH Studies comparing flare rates between pregnant and nonpregnant patients have reported conflicting data (36–38). A number of biomarkers have been associated with increased LN activity, although validation is required before using them to differentiate LN from pre-eclampsia (57–59). Exposure to azathioprine during pregnancy is not associated with poor fetal outcome. Azathioprine tablets should not be given during pregnancy without careful weighing of risk versus benefit. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Clin J Am Soc Nephrol. Pregnancy may have adverse short- and long-term effects on kidney function, including an increased risk for LN flare and progression to ESRD. If conception occurs after a period of 12–18 months (minimum of 6 months) of remission, pregnancies generally have favorable outcomes (34). Importantly, a recent review of the literature identified 17 cases of maternal mortality in pregnancies with LN. Its teratogenicity has been documented in human and animal studies, and consequently, its use should be restricted in women who have not completed childbearing (14,68). Evaluation revealed worsening proteinuria, hypertension, and altered renal function (creatinine 1.6 mg/dl from 1.0 mg/dl baseline). Azathioprine – Azathioprine is compatible with pregnancy, but doses should not exceed 2 mg/kg/day. SLE is a multi-organ autoimmune disease that affects women of childbearing age. The structural formula of azathioprine is: Crohn Disease (Off-label) Maintenance, remission, or reduction of steroid. 2007 May;33(2):237-52, v. doi: 10.1016/j.rdc.2007.01.002. Differentiation of pre-eclampsia, HELLP syndrome, and active lupus nephritis. In addition, normal pregnancy is characterized by a shift from a Th1 cell-mediated to a Th2 antibody-mediated immune response (commonly referred to as Th2 polarization). These should be differentiated from a new onset or LN flare and/or pre-eclampsia, a pregnancy-specific condition clinically characterized by hypertension and proteinuria, and its severe form, HELLP syndrome, characterized by hemolysis, elevated liver enzymes, and low platelet count (Table 1). The authors reported favorable outcomes and, consequently, recommended azathioprine for the treatment of SLE/LN in pregnancy (14). -, Arthritis Care Res (Hoboken). Studies of the immune system in pregnancy are of interest for what they have taught us about the effect of hormones on lupus flares. 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. Pregnancy, though, is considered high-risk due to a combination of maternal (lupus flare, diabetes, pre-eclampsia) and fetal (miscarriage, intrauterine fetal demise, preterm birth, intrauterine growth restriction, congenital heart block) risks. Azathioprine during pregnancy in systemic lupus erythematosus patients is not associated with poor fetal outcome. However, pregnancy outcomes can be optimized if appropriately managed by a multidisciplinary team of physicians, with appropriate preconception counseling and surveillance. 2018 Dec 15;7(12):552. doi: 10.3390/jcm7120552. We reviewed the medical records of SLE pregnant women followed from January 2005 to April 2013. Use of azathioprine/mercaptopurine in pregnancy may sometimes be considered necessary to prevent the rejection of a transplanted organ, or to keep leukaemia or a serious autoimmune illness under control. However, studies that have used a patient's own nonpregnant course for comparison have demonstrated an increased risk of LN flare during pregnancy (15,39,40). 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). Azathioprine is chemically 6-[(1-methyl-4-nitro-1 H-imidazol-5-yl)thio]-1 H-purine. The relationship between LN and pregnancy outcomes is complex. The UK-BIOGEAS Registry: Efficacy of rituximab in 164 patients with biopsy-proven lupus nephritis: Pooled data from European cohorts [published online ahead of print October 18, 2011]. Multivariate analysis showed that preeclampsia, premature rupture of membranes (PROM), lupus flare, and anti-DNA positive were associated with an increased risk of poor fetal outcome. Introduction. Consequently, current recommendations advise that the affected woman achieve a stable remission of her renal disease for at least 6 months before conception. Pregnant women can develop redness (erythema) of palms and face, which is important to differentiate from a … Pregnancy outcomes among Chinese women with and without systemic lupus erythematosus: a retrospective cohort study. Each scored tablet contains 50 mg azathioprine and the inactive ingredients lactose, magnesium stearate, potato starch, povidone, and stearic acid. In lupus, Imuran can reduce damage to joints, decrease the risk for disability, and improve conditions in cases where lupus affects the kidneys (lupus nephritis) or liver. Despite the FDA category, in patients with disease well controlled with azathioprine, treatment may be continued during pregnancy to minimize the risk of flare. Clipboard, Search History, and several other advanced features are temporarily unavailable. Children born to mothers positive for anti-SSA/Ro and anti-SSB/La antibodies are at risk for congenital heart block.
