ABSTRACT

The purpose of this study is to compare group B Streptococcus (GBS) infection incidence in HIV-exposed uninfected (HEU) and HIV-unexposed (HU) infants in a Spanish cohort. We conducted a retrospective study in 5 hospitals in Madrid (Spain). Infants ≤ 90 days of life with a GBS infection were included from January 2008 to December 2017. Incidence of GBS infection in HEU and HU children was compared. HEU infants presented a sevenfold greater risk of GBS infection and a 29-fold greater risk of GBS meningitis compared to HU, with statistical significance. Early-onset infection was tenfold more frequent in HEU children, with statistical significance, and late-onset infection was almost fivefold more frequent in the HUE infants' group, without statistical significance. CONCLUSION: HEU infants presented an increased risk of GBS sepsis and meningitis. One in each 500 HEU infants of our cohort had a central nervous system infection and 1 in each 200, a GBS infection. Although etiological causes are not well understood, this should be taken into account by physicians when attending this population. WHAT IS KNOWN: • HIV-exposed uninfected infants are at higher risk of severe infections. • An increased susceptibility of these infants to group B Streptococcus infections has been described in low- and high-income countries, including a higher risk of meningitis in a South African cohort. WHAT IS NEW: • Group B Streptococcal meningitis is more frequent in HIV-exposed uninfected infants also in high-income countries. • Physicians should be aware of this increased risk when attending these infants.
