IL-10 e TNF-α no sangue materno e nas placentas de gestações complicadas por diabete ou hiperglicemia gestacional leve - correlação com controle glicêmico e resultados perinatais

Objective - At evaluating the IL-10 production in maternal blood and placenta and correlate them with perinatal outcomes in pregnancies complicated by hyperglycemia, or with risk to developing it, differentiated by the glycemic mean (GM < or ≥ 100mg/dL). Method- 186 pregnant women were distributed into groups GM < 100 mg/dL and GM ≥ 100 mg/dL. We evaluated the GM, HbA1c levels, maternal and placental IL-10 and TNF-α and the correlation between placental cytokines and perinatal outcomes. Results - In maternal blood, the lower concentrations of IL-10 (1.01 ± 0.87 vs. 3.08 ± 5.57 pg / mL, p = 0.0019) were observed in GM ≥ 100 mg / dL group. Placental IL-10 was directly correlated with hemoglobin levels (r = 0.63, p = 0.02) and insulin (r = 0.78, p = 0.01) from umbilical cord and with Apgar scores 1 (r = 0.53, p = 0.0095) and Apgar 5 (r = 0.69, p = 0.0003). Conclusion - GM ≥ 100mg/dL was associated with decreased of maternal IL-10. Placental IL-10 was similar in both groups and correlated directly with hemoglobin and insulin and with Apgar scores of 1st. and 5th. minutes

Sanidade Uterina Pós Parto: Aspectos Imunológicos e Terapêuticos

Function of the uterus is often compromised in cattle by bacterial contamination of the uterine lumen after parturition. Pathogenic bacteria often persist, causing uterine disease, a major cause of infertility in cattle. Knowledge of the immunological aspects of the uterus involved in maintaining reproductive healthiness is fundamental to the study of uterine infections that affect the uterus postpartum. Polymorphonuclear leukocytes have an important role because they are the first line of defense against colonization of bacteria in utero (Hammon and Goff, 2006). The establishment of uterine infection depends in parts of endocrine environment, particularly progesterone, which suppresses the immune system (Lewis, 2003). In the puerperium may occur uterine disorders, such as retained placenta, puerperal metritis, clinical and subclinical endometritis and pyometra, this review was proposed a study of the immunology involved in uterine health and a better understanding of uterine disorders, using the model of Sheldon et al. al, (2006) for classification of diseases, and a study of best treatment options and discussion about its functionality, because a lot of controversy among authors about choosing a treatment and another and between treated and untreated
