Women with endometriosis frequently suffer from autoimmune inflammatory diseases, allergies and asthma. This study was conducted to examine whether the prevalence of allergies is higher in patients with endometriosis than in the control group, and to show potential correlation with endometriosis stages. We evaluated the medical files of 501 women with laparoscopically-diagnosed endometriosis and 188 women without endometriosis enrolled in Yale University Hospital. Main outcome measures used were allergy on medications, complaints of sinus or perennial allergic rhinitis, asthma, family history of allergic disease, and correlation with stages of endometriosis. Our results indicated that the overall risk of women with endometriosis and positive history of allergies was 4.28 (95% CI, 2.9-6.3) (p < 0.001). Significant excesses were identified for medications, sinus allergic rhinitis, and asthma; also, women with endometriosis were significantly more likely to report a positive family history of allergies. Overall, our study indicated a link between endometriosis and increased risk of allergic autoimmune disorders that should further be explored.

Angiopoietin-1 and -2 are endogenous ligands for the vascular endothelium-specific receptor tyrosine kinase Tie-2. The angiopoietin/Tie system plays a critical role in the regulation of endothelial cell survival and vascular maturation and stability. Apart from its well-established role in vascular morphogenesis, emerging data support the involvement of angiopoietins in inflammation and various malignancies. Previous studies have underlined the significance of several angiogenic factors in normal placental development. In addition, angiogenic imbalance is observed in pregnancy complications related to impaired placentation, such as preeclampsia (PE) and intrauterine growth restriction (IUGR). However, there is only limited information available on the role of the angiopoietin/Tie system in the establishment of a competent feto-maternal vascular system. In this review, we present the current knowledge regarding the role of angiopoietins in normal pregnancy and pregnancy complications.

The aim of the study was to examine interleukin-6 (IL-6) maternal serum concentration at 11 to 14 gestational weeks in normal pregnancies and pregnancies complicated by gestational diabetes mellitus (GDM) and to create first trimester prediction models for GDM. Case-control study conducted in a Fetal Medicine Unit. Study population included 40 GDM cases and 94 controls. Maternal characteristics, first trimester ultrasound markers, biochemical indices, and IL-6 levels were used for our analysis. IL-6 was related to maternal weight among the maternal characteristics, (R(2)=0.0679, p=0.01). IL-6 was increased (p=0.001) in the GDM group (median=2 pg/ml) compared to the control group (median=1.5 pg/ml) even after adjustment for maternal weight. IL-6 was inversely related to birth weight adjusted for gestational age at delivery (r=-0.3382, p<0.001) and glucose levels at oral glucose test. Maternal weight and age were the only predictors of GDM among the maternal characteristics [Detection Rate (DR)=59.4%; for 25% False Positive Rate (FPR); Area Under the Curve (AUC)=0.7291; Model R(2)=0.1096, p<0.001]. IL-6 alone was a significant predictor of GDM (DR=51.3%; for 25% FPR; AUC=0.6731; Model R(2)=0.0616, p<0.001). Combination of maternal characteristics with IL-6 yielded an improved prediction (DR=67.5%; for 25% FPR; AUC=0.7586; Model R(2)=0.1521, p<0.001). IL-6 concentrations are increased at 11-14 weeks in pregnancies with GDM. Combination of maternal characteristics and maternal serum IL-6 levels may provide effective first trimester screening for GDM.
