Gonococcal infections in neonates and young children

Gonorrhea has been recognized since antiquity, and more than 60 million new cases occur yearly worldwide. Much has been learned about the molecular pathogenesis of infection by Neisseria gonorrhoeae, but immunity from natural infection does not protect against reinfection with the same strain, and the goal of a protective vaccine remains elusive. Gonococcal ophthalmia neonatorum is the most common manifestation in infants born to mothers with gonococcal genital tract infections. Genital and pharyngeal gonococcal infections in young children almost always are acquired from sexual abuse by an infected adult. Invasive disease can occur at any age but is uncommon. Nonculture diagnostic tests are widely used in adults, but culture is required in children for medicolegal purposes. N. gonorrhoeae strains have developed resistance to many antibiotic classes, and resistance profiles vary among geographic regions and within regions over time. Current guidelines for treatment of gonococcal infections in children in the United States are reviewed.

[Gonorrheal ophthalmia neonatorum in a premature infant delivered by cesarean section]

A case of gonococcal ophthalmia neonatorum in a preterm boy (gestational age 29 weeks) delivered by caesarean section 22 hours after rupture of the membranes is described. The neonate made an uneventful recovery after treatment with ampicillin, gentamicin and methicillin for concomitant cutaneous infection.

Prospective study of perinatal transmission of Chlamydia trachomatis

During a five-year period, 262 (4.7%) of 5,531 pregnant women had positive cervical cultures for Chlamydia trachomatis, and 131 of their infants were followed up prospectively to ascertain the outcome of chlamydial exposure during the birth process. Culture-confirmed inclusion conjunctivitis of the newborn was seen in 23 (18%) of the infants. Chlamydial pneumonia was diagnosed in 21 (16%) of the infants at risk. Chlamydia trachomatis was recovered from 47 of the infants (36%), while 79 (60%) showed serologic evidence of infection. Subclinical rectal and vaginal infections were detected in 14% of infants at risk. In our population, 2.8% of newborn infants show serologic evidence of perinatal chlamydial infection and 1.4% develop either chlamydial pneumonia or conjunctivitis. Incidence rates of this magnitude indicate the need for programs aimed at preventing perinatal transmission of C trachomatis.
