Brief Summary:
To compare the effectiveness of silver nitrate drops, erythromycin ointment, or no medication in preventing neonatal conjunctivitis caused by Chlamydia trachomatis and other eye infections.
To compare side effects of the two prophylactic agents.
To compare side effects of the two prophylactic agents.
Detailed Description:
Sexually transmitted diseases are a major cause of neonatal eye infections. All 50 States require some eye treatment at birth to prevent gonorrheal eye infections. Approximately 3 to 4 million Americans acquire a genital chlamydial infection each year, and more than 150,000 infants are born to mothers with chlamydial infections. These infants are at high risk of developing conjunctivitis and pneumonia.
In the State of Washington, one of three treatments is presently required by law to help prevent gonorrheal eye infection in newborn babies: 1 percent silver nitrate drops, erythromycin ointment, or tetracycline ointment. Although all three treatments appear to prevent eye infections from gonorrhea, silver nitrate and erythromycin may also partially prevent chlamydial conjunctivitis. However, silver nitrate may irritate and damage the eyes of newborns.
If it is not known whether the mother is infected, it may be better not to give the drugs routinely. It could not be clearly established from the medical literature whether the risk to infants from no treatment was higher or lower than the risk from receiving a prophylactic agent. Many parents at low risk for gonorrhea prefer that no prophylaxis be given to their newborns. Moreover, Great Britain, which used no eye prophylactic agents for newborns for the 25 years preceding the study, has rates of neonatal conjunctivitis similar to those in the United States. For these reasons, the Washington State Board of Health granted this study an exemption from the State law to allow the investigators to evaluate scientifically the risks and benefits of no treatment.
The study was a randomized, double-masked clinical trials planned to include 1,200 infants born over 3 years. The trial compared the efficacy of two treatment regimens (silver nitrate and erythromycin) in two treatment groups to the outcomes in a control group receiving no prophylaxis. (Erythromycin was chosen over tetracycline as the antibiotic in this study because it is more commonly used in the United States for ocular prophylaxis.)
Women were recruited from the University of Washington Medical Center-associated obstetric units. Among the 2,577 women eligible for possible participation, 758 enrolled. Of these participants, 89 were not randomized. Among the 669 randomized women, 39 were not available for personal observation. These 39 were equally distributed among the three prophylaxis groups. In the final participant group, the infants of 630 women were evaluable.
The infants were randomly assigned to one of these three groups in the delivery room. Infants without conjunctivitis were monitored for 2 months after delivery. Infants who developed conjunctivitis were monitored for 2 months after successful treatment of their infection. The study included extensive efforts to determine the etiology of the conjunctivitis and to find nasolacrimal duct obstruction.
