Risks of Infectious Diseases in Newborns Exposed to Alternative Perinatal Practices

Intersociety Position Statement on the Prevention of Ophthalmia Neonatorum in Italy

There is currently no worldwide agreement on the real need to administer conjunctival antibiotics to neonates at birth to prevent neonatal conjunctivitis (usually defined as ophthalmia neonatorum) by Chlamydia trachomatis and Neisseria gonorrhoeae. Therefore, there is wide variability in antibiotic administration, conditioned mainly by the social and health context. In Italy, a law enacted in 1940 required doctors and midwives to administer ophthalmic prophylaxis with 2% silver nitrate to all newborns at birth. This law was repealed in 1975 and since then there has been no clear guidance on the use of ophthalmia neonatorum prophylaxis at birth. Since neonatal conjunctivitis caused by C. trachomatis and N. gonorrhoeae is not reported, we carried out a nationwide survey of 1,041,384 neonates across all Italian birth centers to evaluate the incidence of ophthalmia neonatorum and the current practice of prophylaxis. After analyzing the results, we formulated an intersociety position statement on the prevention of ophthalmia neonatorum to update and standardize this prevention strategy in Italy.

Prevention of Perinatal Hepatitis B Transmission

Hepatitis B virus (HBV) is efficiently transmitted to newborn infants in the perinatal period and can lead to chronic infection, cirrhosis, liver cancer, and death. Despite the availability of effective prevention measures necessary to eliminate perinatal HBV transmission, significant gaps remain in the implementation of these prevention measures. All clinicians who care for pregnant persons and their newborn infants need to know the key prevention measures including (1) identification of HBV surface antigen (HBsAg)-positive pregnant persons, (2) antiviral treatment of HBsAg-positive pregnant persons with high viral loads, (3) timely postexposure prophylaxis of infants born to HBsAg-positive persons, (4) and timely universal vaccination of newborn infants.

Disquiet concerning cesarean birth

Cesarean birth has increased substantially in many parts of the world over recent decades and concerns have been raised about the propriety of this change in obstetric practice. Sometimes, a cesarean is necessary to preserve fetal and maternal health. But in balancing the risks of surgical intervention the implicit assumption has been that cesarean birth is an equivalent alternative to vaginal birth from the standpoint of the immediate and long-term health of the fetus and neonate. Increasingly, we realize this is not necessarily so. Delivery mode per se may influence short-term and abiding problems with homeostasis in offspring, quite independent of the indications for the delivery and other potentially confounding factors. The probability of developing various disorders, including respiratory compromise, obesity, immune dysfunction, and neurobehavioral disorders has been shown in some studies to be higher among individuals born by cesarean. Moreover, many of these adverse effects are not confined to the neonatal period and may develop over many years. Although the associations between delivery mode and long-term health are persuasive, their pathogenesis and causality remain uncertain. Full exploration and a clear understanding of these relationships is of great importance to the health of offspring.

Neonatal Conjunctivitis

Neonatal conjunctivitis is an important cause of ocular morbidity with infectious and noninfectious origins. Common practice in the United States is to administer prophylactic antibiotic ointment at birth; however, prophylaxis is ineffective for some causes. Moreover, recognition of the etiologies that threaten systemic complications to the neonate is critical in providing timely and appropriate treatment. This review summarizes the clinical features, etiology, and treatment recommendations of various forms of neonatal conjunctivitis.
