Profile of peripheral blood neutrophil cytokines in diabetes type 1 pregnant women and its correlation with selected parameters in the newborns.

PROBLEM: Interleukin (IL)-12, IL-10, tumor necrosis factor-alpha (TNF-alpha), IL-6 and IL-8 alter as pregnancy progresses, implying continuous immune regulation associated with the maintenance of pregnancy. We aimed to evaluate the peripheral blood neutrophil-derived production of these cytokines in the course of pregnancy complicated by type 1 diabetes. METHOD: of study These parameters were measured in samples from healthy non-pregnant (C), diabetic non-pregnant (D), healthy pregnant (P) and pregnant diabetic (PD) women. RESULTS: Neutrophil-derived secretion of TNF-alpha and IL-12 increased along with progression of pregnancy in PD and P groups. The concentration of IL-10 from lipopolysaccharide (LPS)-stimulated neutrophils increased during the course of uncomplicated pregnancy but decreased in diabetic pregnancy. Concentration of IL-8 decreased with the advancing gestational age in P and PD groups. LPS-stimulated neutrophil-derived IL-6 concentration increased only in PD patients. CONCLUSION: Our results show that diabetes creates pro-inflammatory environment thus potentially influencing the outcome of pregnancy. We conclude that neutrophil-derived cytokine production could contribute to the complications seen in pregnant women with type 1 diabetes.

[Use of prenatal health care and risk of infants born small-for-gestational-age. Preliminary results of a case-control study in the Lódz voivodeship]. / Profil korzystania z opieki prenatalnej a ryzyko hipotrofii plodu. Wstepne wyniki badania kliniczno-kontrolnego w woj. lódzkim.

It is well documented that small-for-gestational age (SGA) infants are at an increased risk of perinatal mortality and morbidity. In order to identify the major modifiable risk factors of SGA birth, a case-control study was launched in the area of Lódz voivodeship, Poland. The project was focused on the evaluation of the role of perinatal health services and avoidance of exposure to tobacco smoke in the prevention of SGA births. The study population consisted of mothers of 153 SGA infants (cases) and 93 mothers of control infants. SGA infants were identified as infants with body weight below 10th percentile for gestational age, using Ballarda scale. The controls were non-SGA infants delivered after 37 week of gestation. The infants from both groups were delivered in 26 maternity wards in the Lódz voivodeship within the period of June 1-November 1, 2003. One month after delivery, each mother of SGA and control infants was visited by an interviewer who collected information about her profile of use of perinatal health care and on active and passive exposure to tobacco smoke in pregnancy. Odds ratios and 95% confidence units (CU) were calculated using EpiInfo software developed by CDC, Atlanta, Georgia, US. Late booking for perinatal care (after 12 week of gestation) and less than 5 visits during pregnancy was found to be related to an increased risk of SGA, however, the OR values included unity. About 1/3 of mothers of SGA infants and "of the controls were served mainly by the private health sector. The use of private care was related to a lower risk of SGA: OR= 0.55 95% CI (0.31-0.96). This protective pattern was observed in the population of women aged 19-25 living in rural areas years and with only primary education. The preconception visits to obstetricians and contacts with health educators during pregnancy were also found to have some protective effect, however, the ORs were not statistically significant. The adverse effect of smoking during pregnancy was clearly confirmed in the study population, OR= 2.69 95%CI (1.37-5.33), while the role of passive smoking was difficult to assess due to the small number of nonsmoking women exposed to ETS. There are some indications that the poor use of perinatal health services may account for the elevated risk of SGA births in the Lódz voivodeship. The use of the private health sector is growing and seems to be related to a lower risk of SGA births. More effective tools to prevent maternal smoking have to be developed and implemented in routine perinatal care.

[Neonatal outcome multiple pregnancies at the Neonatal Department of Research Institute of Polish Mother's Memorial Hospital]. / Wyniki leczenia noworodków urodzonych z ciaz o wyzszej krotnosci (> or = 3) leczonych w I "CZMP" w latach 1995-2002.

OBJECTIVES: The purpose of this study was to analyze the course of neonatal period among babies born from truly higher-order multiple pregnancies (> or = 3). DESIGN: The retrospective analysis included 81 infants born from multiple pregnancies (> or = 3), hospitalized in Neonatal Department of Research Institute of Polish Mother's Memorial Hospital between 1995-2001. MATERIALS AND METHODS: Studied population contained 63 babies delivered from 21 triplet pregnancies, 8 newborns from 2 quadruplet pregnancies and ten quintuplets. The groups were analyzed according to gestational age, birth weight, ventilation and hospitalization time as well as early and late consequences of prematurity. RESULTS: Among the multiples (> or = 3) the mean birth weight of triplets, quadruplets and quintuplets was respectively: 1656 g vs 1166 g vs 725 g, the diminished gestational age was also noticed: 32.4 vs 30 vs 26.5 GA. The cesarean section ratio in triplet deliveries was 95%, while quadruplets and quintuplets pregnancies were always delivered by operative interventions. The increase in number of fetuses was significantly associated with prolonged ventilation time (mean 9.5 vs 22.2 vs 57.5 days) as well as the hospitalization (mean 29.1 vs 64.1 s 79.6 days). The differences between mentioned above values reached statistical significance (p < 0.001). One out of three neonates born from triplet pregnancy required ventilatory support (36.6%), whereas in quadruplets and quintuplets this ratio reached 100%. The respiratory distress syndrome treated with surfactant was diagnosed in 7.9% (5/63) of triplets, 37.5% (3/8) quadruplets and 100% of quintuplets among whom 8 babies needed more than one dose of surfactant. The increased risk of unfavorable prematurity outcome (PDA, ROP, BPD, IVH) and neonatal death was highly related to plurality of pregnancy. CONCLUSIONS: Multiple pregnancies resulting from infertility treatment cause many medical problems. Undesirable outcome among neonates delivered from higher-order multiple pregnancies (> or = 3 fetuses) predestine to more judicious approach in the application of assisted reproductive techniques and multiple pregnancies prophylaxis.
