Abstract

The aim of this study was to assess mortality and sequellae within cases from Nationwide survey of community acquired meningitis and identify risk factors for inferior outcome. Risk factors such as underlying disease (diabetes mellitus, cancer, trauma, neonatal age, splenectomy, alcoholism, sepsis, other infections), etiology, clinical symptoms and outcome (death, improvement and cured after modifications of ATB therapy, cured without change of therapy, cured with neurologic sequellae) were recorded and analysed with univariate analysis (chi2 or t test for trends, CDC Atlanta 2004). Analysing risk factors for inferior outcome (death or cured with neurologic sequellae), we compared patients who died or survived with neurologic sequellae to all patients with community acquired bacterial meningitis. Univariate analysis showed that trauma (p0.05), alcohol abuse (p0.05), diabetes, S. aureus (p0.05) and gram-negative etiology (A. baumannii, Ps. aeruginosa or Enterobacteriaceae) (36% vs. 11,9%, p0.05) were predicting inferior outcome. Analysing risk factors for treatment failure (death or failed but cured after change of antibiotic treatment) prior sepsis (34.1% vs. 13.9%, p0.01) and gram-negative etiology (25% vs. 11.9%, p0.02) were statistically significant predictors of treatment failure. Neisseria meningitis had less failures (p0.05). Concerning infection associated mortality again diabetes mellitus (p0.05), alcoholism (p0.05) staphylococcal and gram-negative etiology (p0.05) were significant predictors of death. N. meningitis had surprisingly less treatment failures (appropriate and rapid initial therapy). Neurologic sequellae were more common in patients with alcohol abuse (p0.05), craniocerbral trauma (p0.05) and less common in meningitis with pneumococcal etiology (p0.05).

Abstract

Breakthrough fungaemias due to Candida albicans and Candida parapsilosis appearing during fluconazole therapy in neonates and infants were assessed for risk factors and outcome. Forty fungaemias occurred during therapy with fluconazole within a 12 year national survey and were compared with 161 cases of non-breakthrough paediatric fungaemias. The agar disc diffusion test method was used for antifungal susceptibility testing and the Vitek system for species identification. Univariate and multivariate analysis for risk factors for breakthrough fungaemia were carried out. All the fungaemias were a result of strains susceptible to fluconazole at 0.25-4 mg/L in vitro [C. albicans (85%) and C. parapsilosis (15%)]. The mean number of positive blood cultures per episode was 2.2. Sixteen children had 'early' breakthrough fungaemias (within 4-5 days) and 24 fungaemias appeared on day 6 and later. Mean fluconazole MICs in the 'early' group were 1.2, and 2.8 mg/L in the 'late' group (P < 0.03, t-test). However, no difference was observed in the average dose of fluconazole used in the two groups. Neonatal age, total parenteral nutrition, very low birth weight, before surgery, central or umbilical venous catheterization and artificial ventilation were all significantly related to breakthrough fungaemia in univariate analysis but only central or umbilical venous catheterization were significant in multivariate analysis. The outcome of breakthrough fungaemia was better overall and attributable mortalities in non-breakthrough fungaemia was significantly higher in comparison with breakthrough fungaemia.

Abstract

Healthy child development is under the influence of prenatal and perinatal exposure to stress stimuli. The aim of this study is to test the hypotheses that (1) neonates requiring catecholamine blood pressure support are more often born to mothers with stress-related cardiometabolic diseases, (2) maternal stress-related diseases are associated with more frequent requirement of maternal corticosteroid treatment and (3) antenatal steroid exposure of neonates reduces the need of postnatal catecholamine support. A retrospective cohort study was performed on a sample of 427 mature (13%), preterm (64%) and extremely preterm (23%) neonates of both sexes. Mothers at risk of preterm delivery were treated with dexamethasone. The blood pressure support in neonates was performed by intravenous treatment via umbilical or epicutaneous venous catheter with dopamine (5 ug/kg/min) or dobutamine (5 ug/kg/min) or a combination of both. The results showed a lack of association between maternal stress-related diseases and the complicated outcome of their neonates. Maternal treatment with corticosteroid dexamethasone was associated with lower frequency of catecholamine blood pressure support requirement. Catecholamine support was more needed in male infants. Thus, the occurrence of maternal cardiometabolic stress-related diseases does not appear to be related to the need of catecholamine support in the neonate. In agreement with the second hypothesis, a more frequent maternal corticosteroid treatment was associated with the presence of maternal stress-related diseases. Most importantly, the obtained results support the hypothesis on positive influence of maternal glucocorticoid administration on cardiovascular outcome of the neonate, representing an additional beneficial effect of antenatal corticosteroids. LAY SUMMARY Maternal hypertension, diabetes and obesity, which belong to cardiometabolic stress-related diseases, failed to show a negative influence on neonatal health as was determined by the need of catecholamine blood pressure support in a large sample of 427 immature and mature newborns. Since glucocorticoids are often viewed as negative agents that should be avoided, the important finding of the present study is the beneficial effect of maternal corticosteroid treatment on blood pressure stability of the neonate.

Abstract

Objective: The purpose of this study was to find out whether Procalcitoni, Neopterin and C-reactive protein are sensitive and specific markers of intrauterine infection., Methods: We evaluated 155 patients from 26. to 41. week of pregnancy at the time of delivery. We measured serum concentrations of procalcitonin (PCT), neopterin and C-reactive protein (CRP) from mother's blood sample at the beginning of delivery and from umbilical cord blood after delivery., Results: In first group occurred in higher percentage (27.41%) preterm delivery (26.-37. week of pregnancy), chorioamnionitis confirmed by histological examination (16.12%) and preterm premature rupture of membranes (24.19%). In this group occured perinatal infection of newborn in 61.29%. In the second group preterm delivery (6.31%) and perinatal infection of newborn (7.36%) occured in lower percentage., Conclusion: The results suggest that the simultaneous measurement of CRP, PCT and NPT in mother's blood sample before delivery and umbilical cord blood may provide an accurate early diagnosis of infection and then preterm delivery (Tab. 1, Fig. 3, Ref. 18).
