The increasing knowledge in diagnosis and management of primary systemic vasculitis (SV) has led to an earlier detection and treatment of such diseases with the consequent improvement of survival rate and quality of life. SV are rare diseases and, unlike other autoimmune conditions, they do not preferentially affect women. Therefore our understanding of the relationship between pregnancy and SV is limited. The aim of this study was to describe pregnancy outcome in patients with diagnosis of SV followed in our Institution; to evaluate the influence of pregnancy on maternal disease.


Analysis of 20 pregnancies (prospectively followed by a multispecialistic team) in 15 patients with diagnosis of SV, according to Chapel Hill Consensus Conference and/or ACR Criteria for SV. Two patients were affected by Takayasu arteritis (TA), 3 by Churg-Strauss syndrome (CS), 2 by Polyarteritis nodosa (PA), 8 by Behcet's disease (BD). Data regarding the duration of disease, serological and clinical features, pregnancy outcome, neonatal and maternal complications and therapy during pregnancy were collected from clinical charts.


All the patients conceived during clinical and serological remission of the disease. The median age of the patients at the conception was 33 (range 27–40); 13 patients were Caucasian, 1 from North Africa and 1 from South America. The mean duration of SV before pregnancy was 8 years (range 1–17). Reproductive history of each patient is detailed in the table. There were 2 miscarriages and 2 fetal death in 2 patients (20% of all pregnancies); 4 pregnancies (20%) had complications: 1 preeclampsia, 3 premature deliveries (before 34 week), 1 post-partum haemorrhage and a post-partum disseminated intravascular coagulation (DIC). Flares of the disease appeared in 5 patients (33,3%): 1 PA, 2 TA and 2 BD. We had 18 live births: 5 premature (28%), in particular 1 newborn small for gestational age (SGA), 1 suffered from necrotizing enterocolitis (NEC) and 1 from respiratory insufficiency.


Our data show that conceiving during the remission of the disease and strictly monitoring of the pregnancy seem to be not sufficient to prevent flare of the disease, maternal and neonatal complications. In particular we want to emphasize the elevated frequency of preterm delivery before the 34th week among the live births (28% vs 5% of the general obstetric population of our hospital).
