Pregnancy in Takayasu's arteritis has a high risk of hypertension-related fetomaternal complications: A retrospective study of a Turkish cohort

Poor obstetric outcomes in women with takayasu arteritis: a retrospective cohort study

The objective of this study was to assess the pregnancy outcomes in a cohort of patients who experienced pregnancies before and/or after being diagnosed with Takayasu's arteritis (TA). The present investigation encompassed a total of 88 pregnancies seen in a cohort of 35 patients who met the criteria outlined by the American College of Rheumatology in 1990 for the classification of Takayasu arteritis (TA). Pregnancies were classified into two categories. 1. Pregnancies that occurred before the diagnosis (pre-d or pre-TA) 2. Pregnancies that happened following a diagnosis (post-d or post-TA). Fifty-nine pregnancies (67.0%) occurred in 21 TA patients before the diagnosis with and a complication rate of 15.2%, and twenty-nine pregnancies (33.0%) occurred in 14 patients concomitant with or after TA diagnosis and complication rate 100%. Although the hypertension rate was higher in the pre-d group than in the post-d group, it was not significant (32.2% vs. 10.3%, p = 0.160). However, preeclampsia (20.6% vs. 0%, p = 0.001), low birth weight (27.5% vs. 1.6%, p = 0.001), and prematurity (24.1% vs. 1.6%, p = 0.035) were observed more frequently in the post-d group compared to the pre-d group. The frequency of abortions and in-utero deaths were similar in both groups (p > 0.05). Patients with hypertension had significantly higher rates of preeclampsia (p = 0.003), preterm birth (p = 0.036), low birth weight (p = 0.250), abortion (p = 0.018), in utero death (p = 0.128), and cesarean section (p = 0.005) than those without hypertension. Renal artery involvement was detected in 15 (42.8%) patients. All patients with renal artery involvement had hypertension, and they had significantly more pregnancy complications than the other group (p = 0.001). TA negatively affects pregnancy outcomes. A good control of arterial hypertension before conception and during pregnancy is critical to improve both maternal and fetal outcomes. In addition, detecting renal artery stenosis before pregnancy is important in reducing possible negative pregnancy outcomes.

Chinese guideline for the diagnosis and treatment of Takayasu's arteritis (2023)

Takayasu's arteritis (TAK) is a chronic granulomatous inflammatory disease that involves aorta and its primary branches. It is characterized by wall thickening, stenosis/obliteration or aneurysm formation of the involved arteries. In order to standardize the diagnosis and treatment of TAK in China, a clinical practice guideline with an evidence-based approach is developed under the leadership of National Clinical Medical Research Center for Dermatologic and Immunologic Diseases (NCRC-DID). Eleven recommendations for 11 clinical questions that are important to the diagnosis and treatment of TAK are developed based on the latest evidence and expert opinions combined with real clinical practice in China.

Pregnancy outcomes in Takayasu arteritis patients: a systematic review and meta-analysis

Takayasu arteritis (TA) is a systemic disease affecting women of reproductive age. Similarly to other systemic autoimmune diseases, pregnancies in patients suffering from TA are at high risk for adverse outcomes; however, the precise incidence of adverse events has not been assessed in a systematic approach. To evaluate the prevalence of adverse pregnancy outcomes in TA. Searches were conducted on PubMed, Cochrane Library, Scopus and Cinahl databases from inception to 25 May 2022. Three independent investigators extracted data and assessed the risk of bias using ROBINS-1 tool. We used a random effects model to calculate the prevalence of the adverse pregnancy outcomes in TA, namely miscarriage, hypertension and pre-eclampsia. We calculated the prevalence of the adverse outcomes in pregnancy for TA. We included 27 studies, with 825 pregnancies. The occurrence of miscarriage, hypertension and pre-eclampsia in patients with TA was 16% (CI 12-21%, p < 0.01), 37% (CI 30-45%, p < 0.01) and 14% (CI 8-23%, p < 0.01), respectively. The results of our meta-analysis indicate that pregnancies in patients with TA are at increased risk for adverse pregnancy outcomes compared to the general population, suggesting that pregnant women with TA should be closely monitored.Trial registration: There was no registration for this systematic review. The aim of this study was to evaluate etc in order to be correct by syntax.
