The Antiretroviral Pregnancy Registry was established in 1989 to collect data on birth defects after pregnancy exposures to antiretroviral therapy. Using Registry data, this study estimates the birth defect risk after pregnancy exposures to lopinavir/ritonavir. The analysis population includes all prospective lopinavir/ritonavir-exposed pregnancies enrolled in the Registry from September 2000 through July 2007. Birth defect prevalence after pregnancy exposure is compared with rates from a population-based surveillance system, and first-trimester exposures are compared with combined second/third-trimester exposures. Among 955 live births prenatally exposed to lopinavir/ritonavir, 23 cases with birth defects were reported [2.4%, 95% confidence interval (CI) = 1.5 to 3.6). Among 267 live births with first-trimester exposures, 5 had birth defects (1.9%, 95% CI = 0.6 to 4.3). These rates are similar to the population-based comparator rate of 2.67% and the rate in infants with second/third-trimester exposures (2.6%, 95% CI = 1.6 to 4.1). No pattern of birth defects suggestive of a common etiology was seen. The prevalence of birth defects among infants prenatally exposed to lopinavir/ritonavir is not significantly different from inter...Continue Reading

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
