Background. Further reduction in the group B streptococcal (GBS) disease burden in neonates in the United States awaits an additional prevention strategy, such as maternal immunization.Methods. We performed a prospective, multicenter, case-control study of 33 mothers delivering neonates with early onset GBS infection (cases), and 99 age- and ethnicity-matched mothers colonized with the same capsular polysaccharide (CPS) types delivering healthy neonates (controls). Relative risk and absolute risk were calculated for early onset disease associated with concentrations of type Ia, III, or V CPS-specific antibody in maternal serum.Results. For GBS types Ia and III, maternal CPS-specific antibody concentrations of ≥0.5 µg/mL were associated with a relative risk of approximately 0.1 (95% confidence intervals [CIs], .01-.74 and 0-.72, respectively; P = .02 for each), corresponding to a 90% risk reduction (by logistic regression). For type V, the relative risk was 0.3 (95% CI, .01-3.1), corresponding to a 70% risk reduction. By Bayesian modeling, the risk of early onset disease would decrease by 70% if maternal CPS-specific antibody concentrations for these 3 GBS types were ≥1 µg/mL.Conclusions. Maternal CPS-specific antibody serum concentrations of ≥1 μg/mL at the time of delivery appear to protect most neonates from early onset GBS type Ia and III disease.

Background. Increased pneumococcal loads are associated with severe outcomes. We determined the prevalence of pneumococcal DNA in blood specimens from patients hospitalized with acute lower respiratory tract infection and identified factors associated with invasive pneumococcal pneumonia, bacterial loads, and death.Methods. A total of 8523 patients were enrolled as part of prospective hospital-based surveillance. Blood was collected for quantitative pneumococcal (lytA) detection, and nasopharyngeal specimens were collected for detection of influenza virus and other respiratory viruses by real-time polymerase chain reaction.Results. Of 6396 cases (75%) with lytA results, 422 (7%) were positive for pneumococcal DNA. The prevalences of human immunodeficiency virus (HIV) and influenza virus were 51% (2965/5855) and 8% (485/6358), respectively. On multivariable analysis, HIV infection (adjusted odds ratio [aOR], 2.4; 95% confidence interval [CI], 1.6-3.6), influenza virus coinfection (aOR, 1.4; 95% CI, 1.2-2.1), oxygen therapy during admission (aOR, 1.6; 95% CI, 1.1-2.3) and in-hospital death (aOR, 2.1; 95% CI, 1.1-4.0) were significantly associated with increased pneumococcal load. Among lytA-positive patients, after adjustment for length of hospitalization, duration of symptoms, and oxygen therapy during admission, pneumococcal loads ≥10,000 DNA copies/mL (aOR, 3.6; 95% CI, 1.8-7.2) were associated with increased risk of death.Conclusions. HIV and influenza virus infections were associated with elevated pneumococcal loads, which, in turn, were associated with increased risk of death.
