Introduction Intraventricular hemorrhage (IVH) affects 15–20 % of babies born before 32 weeks of pregnancy. A lot of risk factors of developing IVH are known. The making appropriate recommendations for dealing with infant born less than 32 weeks of gestation aimed at reducing the incidence of IVH is still needed. The study aim was to determine the incidence and analyze risk factors of IVH stage 3 and 4 in infants born before 32 + 0 weeks of pregnancy. Methods The retrospective analysis of 267 preterm babies (24 to 32 weeks of gestation) hospitalized in 2011–2013 at Department of Neonatology, Poznan University of Medical Sciences was performed. The diagnosis of IVH was confirmed by ultrasound scans according to Papille criteria. Stage 3 and 4 of IVH was confirmed in 14 (25 %) newborns from 23 to 24 weeks of gestation; 21 (37.5 %) from 25 to 26 weeks of gestation; 11 (19.6 %) from 27 to 28 weeks of gestation; 9 (16.1 %) from 29 to 30 weeks of gestation; and 1 (1.8 %) from 31 to 32 weeks of gestation. Result The incidence of IVH stage 3 and 4 was higher in children: with less use of AST (OR 1.27; 0.62–2.61), born out of third-level hospitals (OR 2.25; 1.23–4.08), born with asphyxia (OR 3.46; 1.8–6.64), with acidosis treated with NaHCO3 (OR 6.67; 3.78–11.75), those who in the first days of life were treated for hypotension (OR 9.92; 5.12–19.21). Conclusion No or uncompleted antenatal steroid therapy increased probability for development of severe intraventricular hemorrhage. Antenatal steroids therapy should be promoted among women at risk of a premature delivery. Hypotension therapy with catecholamines and acidosis with sodium hydrogen carbonate should be carefully considered. The use of appropriate prophylaxis of perinatal (antenatal steroids therapy women at risk of preterm birth, limiting the indications for the use of catecholamines for hypotension treatment and sodium hydrogen carbonate for acidosis therapy, limitation of preterm deliveries outside tertiary referral centeres) significantly reduces the incidence of intraventricular hemorrhage stage 3 and 4. The significance of intraventricular hemorrhage creates a need to carry out periodical analysis, at regional level, concerning its incidence, causes and effects to improve local treatment outcomes by identifying further courses of action.

Purpose: The aim of the presented study was to evaluate the differences between selected biochemical markers in infants with moderate or severe hypoxic-ischemic encephalopathy (HIE) and their impact on patient prognosis. Methods: A total of 57 cooled newborns were divided into groups according to Sarnat staging of HIE (A, moderate vs. B, severe). The differences between groups were evaluated depending on the mode of delivery, pregnancy and labor complications, gestational age at birth, birth weight, and Apgar score at 1.3 and 5 min. The differences in biochemical biomarkers of HIE (pH, base excess, serum lactate) as well as biomarkers of hepatic injury (aspartate transaminase, (AST), alanine transaminase (ALT), prothrombin time (PT), and activated partial thromboplastin time (APTT)), kidney failure (creatinine, urea), myocardial injury (troponin T (TnT)), levels of fibrinogen, and platelet counts were also examined. Univariate Kaplan-Meier method was used for survival analyses. Results: The biomarker levels in severe HIE newborns compared with moderate were as follows: pH (7.10 vs. 6.99), serum lactate (22.50 vs. 17.00 mg/dL), AST (109.50 vs. 270.55 IU/L), ALT (27.30 vs. 108.05 IU/L), PT (17.00 vs. 44.20 s), APTT (47.75 vs. 47.90 s), TnT (0.22 vs. 0.85 ng/mL), creatinine (0.68 vs. 1.15 mg/dL), urea (44.55 vs. 73.30 mg/dL), and fibrinogen (1.65 vs. 1.90 mg/dL). Survival analyses showed significantly reduced survival for severe HIE infants (75%) vs. moderate HIE (100%). Conclusion: In conclusion, the severity of HIE can be evaluated based on selected markers; however, their levels do not correspond with future prognosis of newborns.

Proinflammatory cytokines are essential mediators and indicators of an inflammatory process occurring in the body. Their physiological role is to stimulate the immune response, yet their excessive propagation and interaction with cells outside the immune system may be linked to the risk of organ damage. This is specifically important in the case of immature tissues of fetuses and prematurely born infants. Analysis of the concentrations of specific cytokines in different compartments makes it possible to assess the risk of premature birth, preterm rupture of the membranes, and to determine an existing intrauterine infection. The purpose of this paper is to summarize the existing research concerning the relationships between the concentrations of specific proinflammatory cytokines in different compartments (maternal blood serum, amniotic fluid, umbilical cord blood, arterial and venous blood, and cerebrospinal fluid of the newborn) and the risk of intraventricular hemorrhage (IVH) and the degree of its severity. The paper takes also into account the assessment of the usefulness of cytokines as biomarkers for IVH and its complications (posthemorrhagic hydrocephalus, white matter injury).

Hypoxic ischemic encephalopathy (HIE) is a serious neurological complication that may develop in asphyxiated infants. Severity of encephalopathy may vary, and concurrent multiorgan dysfunctions are commonly observed. Analyzing the incidence of such complications according to severity of HIE, and how they correlate with each other, may shape clinical judgment and allow for early intervention. The study included a total of 57 HIE infants, in which 27/57 (47.37%) met Sarnat inclusion criteria for moderate stage II HIE (Group A) and 30/57 (52.63%) for severe stage III HIE (Group B). Both groups were assessed and compared for incidence of kidney dysfunction, liver dysfunction, coagulopathy, qualitative cardiac abnormalities, respiratory-related dysfunction, and bone marrow insufficiency/thrombocytopenia. All assessments were performed before initiation of therapeutic hypothermia. The complications were further assessed for the presence of correlations. Group B experienced significantly higher incidence of kidney dysfunction (A: 2/27 [7.4%] vs. B: 21/30 [70%], p < 0.001), liver dysfunction (A: 14/27 [51.8%] vs. B: 28/30 [93.3%], p < 0.001), and thrombocytopenia (A: 8/27 [29.6%] vs. B 21/30 [70%], p = 0.002) in our study group. Kidney dysfunction and bone marrow insufficiency showed the highest affiliation with other organ systems in both groups, correlating positively with each other as well as HIE severity, cardiac abnormalities, liver dysfunction, and infant death. A total of 8/57 (14%) infant deaths were observed, all originating from grade III severe HIE group (p = 0.003). Multiorgan dysfunction showed a significant difference between HIE severity (A: 12/27 [44.4%] vs. B: 28/30 [93.3%], p < 0.001). A positive correlation was obtained between multiorgan dysfunction, HIE severity, and infant death. Stage III HIE infants are more likely to experience abnormalities in the kidneys, liver, bone marrow as compared with stage II HIE infants. Correlations between organ complications are present, and should be taken into account during clinical assessment of HIE infants. The probability of mortality is higher in stage III HIE infants with observed multiorgan dysfunctions.

Introduction Intraventricular hemorrhage (IVH) is mostly documented in premature infants, and the younger the gestational age, the more often it occurs. IVH is very rarely reported in full-term neonates. Case report Retrospective analysis was performed in 35939 full-term neonates, who were born in the Clinical Hospital of Gynecology and Obstetrics at the University of Medical Sciences in Poznań. Clinical data were retrieved from their medical records. We report a case series of 2 term newborns, who developed severe IVH grade 3 and 4 with no evidence of asphyxia, neuroinfection, TORCH infections, coagulation disorders and trombocytopenia, metabolic disorders, arteriovenous malformations, and selected genetic abnormalities (factor V Leiden 1601G > A polymorphism and MTHFR 677C > T; 1298A > C polymorphisms). IVH in both cases was complicated by posthemorrhagic hydrocephalus treated with decompressive lumbar punctures and next ventriculoperitoneal shunt placement. Conclusions In conclusion, several factors influence the predisposition for severe IVH in term neonates. Perinatal period complicated by fetal distress, birth trauma, and severe asphyxia should be taken into account. However, it is possible that etiopathogenesis cannot be defined clearly as in our cases. Cranial ultrasounds in a specific group of term newborns (taking into account risk factors for IVH) should be widely recommended.
