Abstract

Background: BCG vaccination has beneficial nonspecific (heterologous) effects that protect against nonmycobacterial infections. We have previously reported that BCG vaccination at birth alters in vitro cytokine responses to heterologous stimulants in the neonatal period. This study investigated heterologous responses in 167 infants in the same trial 7 months after randomization.

Methods: A whole-blood assay was used to interrogate in vitro cytokine responses to heterologous stimulants (killed pathogens) and Toll-like receptor (TLR) ligands.

Results: Compared to BCG-naive infants, BCG-vaccinated infants had increased production of interferon gamma (IFN-γ) and monokine induced by gamma interferon (MIG) (CXCL9) in response to mycobacterial stimulation and decreased production of IFN-γ in response to heterologous stimulation and TLR ligands. Reduced IFN-γ responses were attributable to a decrease in the proportion of infants who mounted a detectable IFN-γ response. BCG-vaccinated infants also had increased production of MIG (CXCL9) and interleukin-8 (IL-8), and decreased production of IL-10, macrophage inflammatory protein-1α (MIP-1α), and MIP-1β, the pattern of which varied by stimulant. IL-1Ra responses following TLR1/2 (Pam3CYSK4) stimulation were increased in BCG-vaccinated infants. Both sex and maternal BCG vaccination status influenced the effect of neonatal BCG vaccination.

Conclusions: BCG vaccination leads to changes in IFN-γ responsiveness to heterologous stimulation. BCG-induced changes in other cytokine responses to heterologous stimulation vary by pathogen.

The effect of neonatal BCG vaccination vs no BCG vaccination on cytokine responses to heterologous stimulants. Significant results P < .05 are depicted in black. Geometric mean ratio > 1.0 indicates that cytokine levels were higher in BCG-vaccinated infants compared with BCG-naive infants. Data that were not normally distributed were analyzed using quantile regression and differences in medians (95% confidence intervals). As this only applied to interferon gamma (IFN-γ), to aid interpretation, all IFN-γ analyses are displayed on stand-alone axes irrespective of the type of analysis done. Abbreviations: CI, confidence interval; GMR, geometric mean ratio; IFN, interferon; IL, interleukin; IP, interferon-gamma induced protein; LPS, lipopolysaccharide; MCP, monocyte chemoattractant protein; MIF, macrophage migration inhibitory factor; MIG, monokine induced by gamma interferon; MIP, macrophage inflammatory protein; PEPG, peptidoglycan; TNF, tumor necrosis factor.

Interleukin 6 (A), interleukin 1β (B), and remaining cytokine/stimulant pairs (C) with a significant interaction between sex and BCG vaccination. Geometric mean ratios (GMRs) and 95% confidence intervals (CIs) are shown for the effect of infant BCG vaccination on all study participants (i), girls (ii), and boys (iii). D, Cytokine/stimulant pairs with a significant interaction between maternal BCG vaccination and BCG vaccination. GMRs and 95% CIs are shown for the effect of infant BCG vaccination on all study participants (i), infants whose mothers were BCG-vaccinated (ii), and infants whose mothers were BCG naive (iii). GMR > 1 indicates that cytokine production is higher in BCG-vaccinated infants. Abbreviations: CI, confidence interval; GMR, geometric mean ratio; IFN, interferon; IL, interleukin; LPS, lipopolysaccharide; MIG, monokine induced by gamma interferon; MIP, macrophage inflammatory protein; PEPG, peptidoglycan; TNF, tumor necrosis factor.
