Pregnancy outcomes in mixed connective tissue disease: a multicentre study. Rheumatology (Oxford). 2019 Nov 1;58(11):2000-2008http://hdl.handle.net/10668/13943In this study we aimed to investigate foetal and maternal pregnancy outcomes from a large multicentre cohort of women diagnosed with MCTD and anti-U1RNP antibodies. This multicentre retrospective cohort study describes the outcomes of 203 pregnancies in 94 consecutive women ever pregnant who fulfilled the established criteria for MCTD with confirmed U1RNP positivity. The foetal outcomes in 203 pregnancies were as follows: 146 (71.9%) live births, 38 (18.7%) miscarriages (first trimester pregnancy loss of In our multicentre cohort, women with MCTD had a live birth rate of 72%. While the true frequency of heart block associated with anti-U1RNP remains to be determined, this study might raise the consideration of echocardiographic surveillance in this setting. Pregnancy counselling should be considered in women with MCTD.enAnti-U1RNPAntibodiesAutoimmune diseaseCongenital heart blockMixed connective tissue diseaseNeonatal lupusPregnancyPregnancy complicationsAbortion, spontaneousAdultAutoantibodiesDiabetes, gestationalFemaleFetal growth retardationHeart blockHumansHypertension, pregnancy-inducedInfant, newbornLive birthLupus erythematosus, systemicMixed connective tissue diseasePregnancyPregnancy complicationsPregnancy outcomeRetrospective studiesRibonucleoprotein, U1 small nuclearStillbirthResearch article31079145open accessAborto espontáneoAutoanticuerposBloqueo cardíacoComplicaciones del embarazoDiabetes gestacionalEmbarazoHipertensión inducida en el embarazo10.1093/rheumatology/kez1411462-0332https://iris.unito.it/bitstream/2318/1715037/2/Pregnancy%20outcomes.pdf
