The mechanisms underlying HEU infants' increased susceptibility to RSV are unclear.METHODSWe recruited pregnant women with and without HIV, plus HEU and HIV-unexposed (HUU) children at 12-18 months of age and collected peripheral and cord blood. We measured innate immune responses of infants to RSV using an in vitro model of human respiratory infection. These responses were correlated with markers of inflammation in maternal and cord blood. We also incubated HUU cord blood cells in plasma from women living with HIV (WLHIV) to recapitulate the RSV-specific responses in HEU cord blood cells.RESULTSWe enrolled 30 WLHIV, 61 HIV-negative women, 19 HEU and 20 HUU children. At birth, HEU infants demonstrated lower expression of IL-12 by dendritic cells (p<0.0001) and IFNγ by natural killer (NK) cells (p=0.007); the difference in IL-12 expression persisted to 12-18 months of age (p=0.015). WLHIV had high concentrations of multiple inflammatory molecules in peripheral blood; these correlated inversely with infant RSV-specific immune responses. Incubation of cord blood cells from HUU infants in maternal plasma from WLHIV significantly lowered RSV-specific NK cytotoxicity and antigen-presenting cell activation compared to incubation in HIV-negative maternal plasma.DISCUSSIONMaternal inflammation is a likely driver of innate immune dysregulation in HEU infants and predisposes to an increased susceptibility to RSV infection.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145127042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Strong health systems are essential for sustaining progress and preventing other health threats from disrupting and potentially reversing the gains that have been made in the fight against HIV. The US President's Emergency Plan for AIDS Relief has a strong track record of building capabilities in laboratories, the supply chain, disease surveillance, data analytics, and the health workforce; however, the impact on national health systems has been uneven. A diagonal approach should therefore be used going forward, blending disease-specific funding with system-strengthening investments. If this strategy is more intentional on integrating the HIV response into national health systems, including national public health institutions, while increasing resilience to other health threats, it should yield results not only for the HIV response but also for other priority diseases and broader health security.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":"39 1","pages":"S121-S124"},"PeriodicalIF":0.0,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145103320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a hamster model of YF, we worked backwards from observations in humans to examine early events that precipitate the intoxication phase of YF. Severe gastrointestinal damage was a surprising feature of HA-YFV pathology. This was defined by early signs of ischemia followed by ischemia-induced erosion of the gut epithelial barrier, which served as an entry point for luminal bacteria that opportunistically spread via the portal system. Thus, the intoxication phase of YF is a sepsis-like syndrome caused by translocation of bacteria from a damaged intestinal tract. Evaluation of human YF cases for these previously disconnected disease features confirmed this overarching mechanism: bacteria were identified in the portal vein and liver parenchyma of fatal YF cases along with elevations in plasma markers of intestinal damage and bacteremia. These findings tie together several recent and historically unexplained observations surrounding the highly-lethal intoxication phase of YF in humans: a high AST/ALT ratio, “black vomit,” pancreatitis, and paradoxical neutrophilia, with implications for treating and prevent YF intoxication.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":"82 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145116534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
