    Notes: Abstract To determine the role of tracheal colonization at birth with Ureaplasma urealyticum and other pathogenic bacteria with regard to the development of bronchopulmonary dysplasia (BPD), 97 premature infants with very low birth weight (〈1500 g) were followed prospectively over 30 days in a multicentre study. Of those infants, 35 were colonized with Ureaplasma urealyticum (group Ia), 22 with other pathogenic bacteria (group Ib) and 40 infants with sterile tracheal aspirates served as controls (group II). Colonization with Ureaplasma urealyticum or with pathogenic bacteria independently increased the risk of developing BPD as compared to the controls (OR 2.55; 95% CI [1.11, 5.87]). Among Ureaplasma urealyticum and bacterial colonized infants, duration of mechanical ventilation and oxygen requirement were significantly longer than among controls (P 〈 0.05); during the interval of 11 to 35 days of life, every additional day of ventilation significantly increased the risk of BPD (OR 1.22; CI [1.12, 1.32]). The rate of oxygen supplementation, which was similar in both groups during the first 2 weeks of life, was significantly higher among the colonized infants at day 21 (0.38 ± 0.18 and 0.39 ± 0.16 vs 0.31 ± 0.13, P 〈 0.05) and at day 28 (0.38 ± 0.21 and 0.34 ± 0.15 vs 0.28 ± 0.12, P 〈 0.05). For infants still ventilated at age of 28 days, Ureaplasma urealyticum and bacterial colonization were associated with a significant higher risk for BPD than for uncolonized controls (OR 5.53; [1.27, 24.02]. Association of Ureaplasma urealyticum and of bacterial colonization and BPD was not weakened after adjustments were made in a multivariate analysis for other significant risk factors. Conclusion Ureaplasma urealyticum colonization is as an important risk factor in the development of bronchopulmonary dysplasia as bacterial colonization even after treatment with surfactant.

    Notes: Summary The effects ofUreaplasma urealyticum colonization on pregnancy and neonatal outcome was prospectively studied in women with impending term or preterm delivery. One hundred and seventy women colonized withU. urealyticum as the only pathogenic microorganism and 83 women with negative cultures were enrolled for study. Compared to the controls,U. urealyticum colonization was associated with a significantly increased rate of amnionitis (2% vs 35%; p〈0.001), chorioamnionitis (0% vs 10%; p〈0.05), premature rupture of membranes (12% vs 35%; p〈0.001) and preterm delivery (10% vs 41%; p〈0.001). The rate of vertical transmission ranged from 38% in term infants to 95% in very low birth weight infants.U. urealyticum colonization at birth was associated with an increased risk for the development of respiratory distress syndrome (9% vs 51%), intraventricular hemorrhage (1% vs 7%) and bronchopulmonary dysplasia (4% vs 17%) in very low birth weight infants (〈1500 g). It is concluded that maternalU. urealyticum colonization is associated with amnionitis, chorioamnionitis and preterm delivery, and that tracheal colonization withU. urealyticum increases the risk for respiratory and neurological complications in very low birth weight infants.

    Description / Table of Contents: Summary Background: Lipoprotein (a) is an important codominantly inherited risk factor for coronary disease but there is little data about its distribution in childhood. Methods: We measured Lipoprotein (a) plasma levels in 111 healthy children. In 37 of these children we also measured Lipoprotein (a) levels of both parents (family study) and obtained a detailed family history with regard to coronary risk factors. Results: The Lipoprotein (a) plasma level (mean and SD) was 16±20 mg/dl (Median 9 mg/dl). 23 children (20%) had elevated levels (≥30 mg/dl). These children also had significantly elevated total cholesterol and LDL-cholesterol levels. Lipoprotein (a) was significantly correlated to total and LDL-cholesterol (p〈0.0001). Lipoprotein (a) levels were independent of age. In the family study, six children had elevated Lipoprotein (a) levels and in each case the Lipoprotein (a) level of one parent was also elevated. Coronary risk factors (hypertension, smoking, overweight as well as increased levels of cholesterol, triglycerides, LDL-cholesterol or Lipoprotein (a) respectively) were quit prevalent in the participating parents (only 12% of fathers and 28% of mothers were free of risk factor) but with regard to the lipid parameters also in their children. Conclusion: Lipoprotein (a) plasma levels together with LDL-cholesterol levels are early markers of coronary risk. Population screenings for Lipoprotein (a) and LDL-cholesterol in children could help to identify individuals at increased risk already in childhood and to stabilize their LDL-cholesterol early at lower levels, particularly in those with elevated Lipoprotein (a) concentrations.
    Notes: Zusammenfassung Hintergrund:Über die Plasmaspiegel des Lipoprotein (a), einem bedeutenden kodominant vererbten Risikofaktor für koronare- und zerebrovaskuläre Erkrankungen, ist bei Kindern wenig bekannt. Methode: Wir untersuchten die Lipoprotein-(a)-Werte bei 111 gesunden Kindern (Altersverlaufstudie), davon in 37 Fällen auch die der jeweiligen Eltern (Familienstudie) und dokumentierten mit Hilfe eines Fragebogens anamnestisch erfaßbare koronare Risikofaktoren. Ergebnisse: Der Mittelwert der Lipoprotein-(a)-Serumkonzentration in der Altersverlaufstudie betrug 16±20 mg/dl (Medianwert 9 mg/dl). Von den untersuchten Kinder hatten 23 (20%) erhöhte Werte (≥30 mg/dl). Dies ging einher mit signifikant erhöhten Mittelwerten für Gesamt- und Low-Density-Lipoprotein-Cholesterin (LDL-Cholesterin) gegenüber der übrigen Population. Es fand sich eine deutlich positive Korrelation zwischen den Lipoprotein-(a)-Werten und den Serumkonzentrationen von Gesamt- bzw. LDL-Cholesterin (p〈0,0001). Vom Lebensalter waren die Lipoprotein-(a)-Werte hingegen unabhängig. In der Familienstudie wiesen 6 Kinder erhöhte Lipoprotein-(a)-Werte (≥30 mg/dl) auf. Bei jedem fand sich auch bei einem Elternteil eine erhöhte Lipoprotein-(a)-Konzentration. Bei 4 weiteren Elternteilen mit erhöhte Lipoprotein-(a)-Werte lagen die Lipoprotein-(a)-Werte des Kinds jedoch im Normalbereich. Die Prävalenz koronarer Risikofaktoren (familiäre Belastung, Hypertonie, Zigarettenrauchen, Übergewicht, Vermehrung von Cholesterin, Triglyzeriden, LDL-Cholesterin oder Lipoprotein (a) im Serum) war besonders bei den untersuchten Eltern (nur 12% der Väter und 28% der Mütter waren frei von diesbezüglichen koronaren Belastungen), hinsichtlich der Fettstoffwechselparameter aber auch bei deren Kindern auffallend hoch. Schlußfolgerung: Lipoprotein (a) eignet sich zusammen mit LDL-Cholesterin als früher Marker zur Erkennung eines Hochrisikokollektivs. Im Rahmen eines generellen Lipid-Screenings bereits im Kindesalter könnten solche Kinder frühzeitig entdeckt werden mit dem Ziel, ihre LDL-Cholesterinwerte kompensatorisch langfristig auf niedrigem Niveau zu stabilisieren.

    Notes: Summary We present two premature infants with disseminated neonatal adenovirus infection, whose epidemiology, clinical course and outcome differ to a great extent. The first infant, born vaginally at 35 weeks gestational age after premature rupture of membranes and maternal illness, developed pneumonia, hepatitis and coagulopathy and died of circulatory failure at the age of 17 days. The other infant, delivered by cesarian section at 36 weeks gestational age, did – in contrast to all documented cases in the literature – not show any signs of pneumonia and survived meningitis without sequelae. The mode of transmission of the viral infection may have been via the maternal birth canal in the first infant and transplacental in the second one. Diagnosis was obtained by direct immunofluorescent test and serology in the first patient and by maternal serology and the detection of viral antigen in tracheal aspirates (ELISA) in the second patient. Disseminated neonatal adenovirus infection has a high mortality and should be considered in the differential diagnosis of neonatal sepsis, especially when pneumonia, hepatitis and neurologic symptoms develop together with thrombocytopenia or disseminated intravascular coagulopathy.
