azathioprine pregnancy lupus

Pregnancy may have adverse short- and long-term effects on kidney function, including an increased risk for LN flare and progression to ESRD. 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). 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 (77). Introduction. 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). 2018 Apr 13;8(4):e020909.

In addition, Imuran has proven to clearly improve lupus affecting the liver and kidneys. Because data regarding its safety in pregnancy are lacking, rituximab should be avoided until its safety and efficacy have been demonstrated. Heparin (blood thinner): Heparin is safe for use during pregnancy but it should be stopped prior to the delivery to decrease the risk of bleeding (especially if a caesarian section is required). Up to 75% of patients with SLE have clinically evident renal disease, which is one of the American College of Rheumatology criteria used for the classification of SLE (34). doi: 10.1136/bmjopen-2017-020909.

Almost all women with lupus can have a successful pregnancy, but some pregnancies will be more challenging than others. For example, mycophenolate mofetil and cyclophosphamide, frequently used for proliferative forms of LN, are contraindicated during pregnancy. Recent studies have reported more favorable outcomes, and patients are seldom counseled against pregnancy (5,6). A meta-analysis reported the presence of antiphospholipid antibodies in approximately one-quarter of lupus pregnancies (41). A recent meta-analysis reported rates ranging from 1.5% to 83% for a LN flare during pregnancy. Evaluation revealed worsening proteinuria, hypertension, and altered renal function (creatinine 1.6 mg/dl from 1.0 mg/dl baseline). Corticosteroid use had been associated with orofacial clefts during pregnancy in both animal models and human patients (69,70). Azathioprine is chemically 6-[(1-methyl-4-nitro-1 H-imidazol-5-yl)thio]-1 H-purine. 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). It is used in rheumatoid arthritis, granulomatosis with polyangiitis, Crohn's disease, ulcerative colitis, and systemic lupus erythematosus, and in kidney transplants to prevent rejection. Antepartum management of patients with histories of LN should focus either on the treatment of active disease or on prevention of a LN flare. For women with antiphospholipid antibodies who do not meet the clinical criteria for APS, an acceptable approach is close clinical surveillance; other options include antepartum aspirin, or prophylactic UFH or LMWH. World Health Organization LN classes I, II, and V are known to have low activity and chronicity indices, whereas classes III and IV tend to be more aggressive and are associated with an increased incidence of LN flare (54,55). A systematic review and meta-analysis of pregnancy outcomes in patients with systemic lupus erythematosus and lupus nephritis. Systemic Lupus Erythematosus (SLE) is an autoimmune disease mostly affecting women of childbearing age (Gergianaki et al., 2018).In the last decades, the rate of successful pregnancies for these women has greatly increased, thanks to the general improvement in SLE management, but also to the availability of drugs compatible with pregnancy and lactation (Lazzaroni et al., 2016). during pregnancy in renal transplant recipients and patients with systemic lupus erythematosus, opin- ions vary whether it should be continued in preg- nancy in inflammatory bowel disease. Given the increased risk of maternal and neonatal morbidity associated with active LN (42), with the risk for flare as high as 70% (43), close monitoring with monthly assessments of disease activity is recommended. Fetal Toxicity of Immunosuppressive Drugs in Pregnancy. Epub 2011 Apr 19. The major goal of immunosuppressive therapy in pregnancy is control of disease activity with medications that are relatively safe for a growing fetus. The risk of pre-eclampsia ranges from 11% to 35%, although most reports show that the risk is closer to 30% (14,17–19) compared with a risk of approximately 5% in the general population. Exposure to azathioprine during pregnancy is not associated with poor fetal outcome. 2015;34(7):1211-1216. Importantly, a recent review of the literature identified 17 cases of maternal mortality in pregnancies with LN. This pilot study aimed to determine whether SLE therapy during pregnancy was associated with developmental delays in offspring. At 12 weeks, she presented with chest pain and shortness of breath. Anti-inflammatory and immunosuppressive drugs in pregnancy. It is taken by mouth or injected into a vein. Azathioprine use in pregnancy has been studied predominantly in women with inflammatory bowel disease, and in those with prior renal transplantation. The increased volume of distribution with the progression of pregnancy may result in low maternal levels of either tacrolimus or cyclosporine; doses may need to be adjusted based on trough blood levels. 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, sold under the brand name Imuran, among others, is an immunosuppressive medication. Active renal involvement is defined as the presence of active urine sediment (>5 red and white blood cells per high-powered field and/or ≥1 cellular casts) and/or proteinuria >0.5 g/d, with or without an elevation in serum creatinine. These data have been corroborated by numerous other studies (19,21–25). Global disease activity in the 6 months prior to the change in therapy and 6 months after the change was calculated. Azathioprine During the First Trimester of Pregnancy in a Patient with Vogt-Koyanagi-Harada Disease: A Multimodal Imaging Follow-Up Study. Am J Case Rep. 2019 Mar 7;20:300-305. doi: 10.12659/AJCR.914281. Baseline laboratory studies (Table 3) may be repeated at the first prenatal visit and should certainly be obtained if no preconception counseling took place. 2020 Feb;59(2):175-177. doi: 10.1111/ijd.14513. -, Lupus. 2018 Dec 15;7(12):552. doi: 10.3390/jcm7120552. from the Eunice Kennedy Shriver National Institute of Child Health & Human Development. 118: Antiphospholipid syndrome. This distinction is critical because LN is managed with immunosuppression, whereas delivery, even remote from term, is indicated for severe and superimposed pre-eclampsia. The GFR increases by 50% to 60%, with a subsequent increase in creatinine clearance of approximately 30%. Because warfarin is contraindicated during pregnancy due to its teratogenicity and potential for life-threatening hemorrhage in the infant (64), patients treated with warfarin should receive therapeutic anticoagulation with either unfractionated heparin (UFH) or low molecular weight heparin (LMWH) when pregnant. Flow diagram of the management of lupus nephritis in pregnancy. 2019 Oct;28(12):1417-1426. doi: 10.1177/0961203319877247. Delivery may be best in a tertiary care center where neonatologists are available, particularly if a patient is likely to deliver before 37 weeks of gestation. Because lupus is a disease that strikes predominantly young women in the reproductive years, pregnancy is both a practical and a research issue. 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). 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). Azathioprine is considered safer in pregnancy than other immunosuppressants, which typically have more severe side effects and a higher risk of effects on babies. 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. 2012 Mar;25(3):261-6. doi: 10.3109/14767058.2011.572310. Cutaneous lupus erythematosus: A review of the literature. Monthly prenatal visits are indicated, with the frequency of laboratory testing depending on the activity of SLE/LN. Estrogen should be avoided in women with active lupus or at high risk for having a … Practice Bulletin No ACOG; American College of Obstetricians and Gynecologists Committee on Practice Bulletins-Obstetrics: ACOG Practice Bulletin No. Epub 2010 Aug 5. Continuous renal replacement therapy was initiated for fluid overload, and vasopressors were required. 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. Please enable it to take advantage of the complete set of features! Fecundity may be decreased by the presence of antiphospholipid antibodies, progressive renal insufficiency, and previous treatment with cytotoxic alkylating agents. The mainstay of management is anticoagulation (see Medical Management: Chronic Anticoagulation), which seems to improve both maternal and fetal outcomes. Imuran is often prescribed to be taken with a corticosteroid. However, pregnancy outcomes can be optimized if appropriately managed by a multidisciplinary team of physicians, with appropriate preconception counseling and surveillance. Serum creatinine in a pregnant woman is lower than in a nonpregnant woman, and varies by trimester. Lupus. 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).

Rheum Dis Clin North Am. We reviewed the medical records of SLE pregnant women followed from January 2005 to April 2013. 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. In pregnant patients with SLE, immunosuppressive therapy is indicated as induction therapy for either flare, new onset disease, or maintenance therapy for patients in remission. Reported outcomes were poor; consequently, therapeutic abortion was frequently recommended (1–4). Azathioprine (Imuran) Imuran is an anti-inflammatory immunosuppressive that can decrease joint damage and disability in people with lupus, rheumatoid arthritis, and other conditions. -, Arthritis Care Res (Hoboken). 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. Each scored tablet contains 50 mg azathioprine and the inactive ingredients lactose, magnesium stearate, potato starch, povidone, and stearic acid. togglers. Although early studies reported high complication rates, including gross hematuria in 16.7% and perirenal hematoma in 4.4% (61), more recent series report similar complication rates to nonpregnant women (62,63). Pregnant women can develop redness (erythema) of palms and face, which is important to differentiate from a … Calcium and vitamin D3 are encouraged before and during pregnancy. ... and neonatal lupus (NL) syndromes are seen in lupus pregnancy. The authors reported favorable outcomes and, consequently, recommended azathioprine for the treatment of SLE/LN in pregnancy (14). 2010 Nov;5(11):2060-8. doi: 10.2215/CJN.00240110. 2016 Oct;36(10):1431-7. doi: 10.1007/s00296-016-3525-0. Consequently, current recommendations advise that the affected woman achieve a stable remission of her renal disease for at least 6 months before conception. 6-MP is used to treat some cancers. 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 . These pregnancies should be monitored by fetal cardiac auscultation, echocardiography, and neonatal electrocardiography after delivery (49). The rate of live births, spontaneous abortions mean birth weight, weeks of gestation, rate of birth weight <2500 g, and low birth weight at term did not differ between groups. The keys to increasing the chances of having a healthy mother and baby is planning the pregnancy, using medications that are compatible with pregnancy to control lupus, and close monitoring by a rheumatologist and obstetrician. The patients were evaluated at least once in each trimester and postpartum. Pregnant patients with SLE and LN are best managed throughout pregnancy by a multidisciplinary team, including an obstetrician (optimally a maternal fetal medicine specialist), a rheumatologist, and a nephrologist (Figure 2). Methods: Lupus patients were identified from the University of Toronto Lupus Clinic database. Because dexamethasone and betamethasone both cross the placenta and reach the fetus at high concentrations, their use is best reserved for obstetrical indications only (67,68). In the absence of antiphospholipid antibodies, prophylactic anticoagulation should be considered for pregnant LN patients with nephrotic syndrome, because the hypercoagulable state inherent to nephrotic syndrome may worsen further with pregnancy, leading to an increased risk for thromboembolic complications (65). Caution should be given particularly to sucrose-containing IVIG because it has been associated with renal insufficiency, although this association was not noted in a review of the use of IVIG in nonpregnant LN patients (82). SLE is a multi-organ autoimmune disease that affects women of childbearing age. 2012 May;31(5):813-9 I believe they used to think it could be toxic but have since found no increased risk in studies. This emphasizes the importance of planning pregnancy, judicious use of immunosuppressive therapy, and the need for expert monitoring (48). -, Teratology. Take a 0.4mg supplement of folic acid for three months prior to pregnancy and during the first 12 weeks of pregnancy to... Stop smoking. Having been in a wheelchair, just over six stone, in constant severe pain and desperately weak, I really had no option. This is an immense change from the 1970’s, when most women with lupus were counseled not to become pregnant. NIH 1996 Apr;5(2):113-9 Ingolotti M, Schlaen BA, Roig Melo-Granados EA, Ruiz García H, Aguilera Partida JA. Pregnancy outcomes in women with childhood-onset and adult-onset systemic lupus erythematosus: a comparative study. Saavedra MÁ, Miranda-Hernández D, Sánchez A, Morales S, Cruz-Domínguez P, Medina G, Jara LJ. Renal biopsy (electron microscopy as shown) disclosed membranous GN. Consideration for using tacrolimus over cyclosporine for induction should be given, on the basis of data suggesting comparable rates of remission achieved with tacrolimus compared with the regimen with cyclophosphamide (79). For example, the number of Tregs is diminished in pre-eclamptic relative to normotensive pregnancies (9). These considerations present challenges that underscore the importance of a multidisciplinary team approach when caring for these patients, including a nephrologist, rheumatologist, and obstetrician who have experience with these pregnancy-related complications. Because oocyte retrieval exposes women to high doses of estrogen, which may increase the risk of flare, it should be performed during disease remission (53). Common side effects include bone-marrow suppression and vomiting. D, immune deposits; GBM, glomerular basement membrane; TRS, tuboreticular structure. Flares can occur at any gestational age, as well as in the postpartum period (17). Epub 2019 Sep 24. Therefore, the use of mycophenolate mofetil, due to increasing evidence supporting its teratogenicity, is contraindicated during pregnancy. Your doctor or specialist will be able to help you make decisions about your treatment. Several reports have supported the safety and efficacy of its use in pregnancies complicated by LN, and its discontinuation in gravid patients increases the risk of lupus flare (Figure 1) (72–76). The risks and benefits of biopsy versus delivery should be considered with the obstetrical and neonatal providers. 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. In addition, membranous LN (class V) ideally would be treated with renin–angiotensin blockade, but these agents are contraindicated in pregnancy. Systemic lupus erythematosus and pregnancy: the challenge of improving antenatal care and outcomes. Fetal demise was documented, maternal evaluation was consistent with brain death, and support was withdrawn. SLE is a multi-organ autoimmune disease that affects women of childbearing age. As a result, the US Food and Drug Administration (FDA) assigned azathioprine to category “D.” Data regarding the use of azathioprine in pregnancy complicated by SLE are limited to one cohort of 31 pregnancies.

Low doses (5–10 mg/d) are unlikely to cause adrenal insufficiency and thymic hyperplasia in infants (66). Active nephritis was associated with an increased risk of hypertension in pregnancy, whereas both active nephritis and a history of nephritis conferred increased risks of hypertension and pre-eclampsia compared with SLE patients without histories of LN (41). Rheumatol Int. I felt even better on Mycophenolate Mofetil but, very disappointingly, was unable to tolerate it. HHS In the setting of Th2 polarization, Th2-mediated diseases, such as SLE, may worsen during pregnancy. Similarly, antihypertensives with adverse fetal effects, such as angiotensin converting enzyme inhibitors and angiotensin II receptor blockers, should be changed to alternatives safe for use during pregnancy. Consideration should be given to consultation with an anesthesiologist regarding intrapartum analgesia in cases with evidence of thrombocytopenia or coagulation abnormalities. Our study suggests that the use of azathioprine is safe and lacks of teratogenity in patients with SLE and pregnancy. This site needs JavaScript to work properly. Crohn Disease (Off-label) Maintenance, remission, or reduction of steroid. Both induction and maintenance regimens are commonly based on corticosteroid therapy, azathioprine, and calcineurin inhibitors (e.g., cyclosporine and tacrolimus), which have acceptable safety profiles in pregnancy. 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. A prospective study, Frequency of lupus flare in pregnancy. Our study suggests that the use of azathioprine is safe and lacks of teratogenity in patients with SLE and 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. This pilot study aimed to determine whether SLE therapy during pregnancy was associated with developmental delays in offspring. Preterm delivery was associated with LN (OR, 18.9), anti-Ro antibodies (OR, 13.9), hypertension (OR, 15.7), and SLE flare (OR, 2.5) (20). The incidence and prevalence of SLE are 1.4–21.9 and 7.4–159.4 per 100,000 people, respectively, although women are disproportionately affected, as reflected by a female prevalence of 9:1 (12). Sufficient time should be allowed for proper washout (at least 6 weeks for MMF). Epub 2019 Jun 10. To date, evidence supporting its efficacy in the management of LN during pregnancy is promising, but limited (80). As SLE onset is often in young adulthood, pregnancy is common and is usually successful. 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). Publication date available at www.cjasn.org. Cut out alcohol. Imuran (azathioprine) is a medication originally used to prevent rejection of transplanted organs. In the body, azathioprine breaks down into 6-MP. Hello DaftCat, have been on Azathioprine for about seven years for a very severe lupus flare ( top two percentile). J Clin Med. The patient should be apprised of the potential hazard to the fetus if azathioprine is used during pregnancy or if the patient becomes pregnant while taking this drug. Int J Dermatol. With respect to tacrolimus, although only rare fetal effects have been documented with its use, the risk of pre-eclampsia, relative to cyclosporine, may be increased (78). A recent LN flare is a risk factor for recurrence; consequently, renal function should be stable without evidence for an active LN flare for a minimum of 6 consecutive months on a medical regimen that is safe to continue throughout pregnancy (12). Renal biopsy should be considered if the laboratory evaluation is nondiagnostic. Therefore, anticoagulation is indicated for all SLE patients positive for antiphospholipid antibodies and a history of thrombotic event(s), regardless of whether they were receiving anticoagulation before pregnancy. Int J Womens Dermatol. 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. Children born to mothers positive for anti-SSA/Ro and anti-SSB/La antibodies are at risk for congenital heart block.
