Methods A multicenter vaccine cohort was followed for 3 years, and the investigation period was classified into the pre-Omicron, Omicron, and endemic eras. Thirteen sampling points were assessed, including pre- and post-MonoV administration. Specimens were classified as vaccinated, molecularly or serologically diagnosed breakthrough infection (BI), natural boosting (NB), or waned. Results A total of 327 healthcare workers contributed 2645 blood samples from March 2021 to December 2023. The log10 anti-spike protein antibody (SAb) levels, elevated by vaccination, declined linearly in the pre-Omicron era, were maintained during the Omicron era due to BIs, and increased in the endemic era (slope = 0.02, P = .02) without additional vaccination. NB cases increased significantly across the epidemiologic eras. The incidence rate ratios were 2.72 (P < .001) for Omicron/pre-Omicron and 3.39 (P < .001) for endemic/Omicron. Plaque reduction neutralization test (PRNT) titers against circulating strains (XBB.1.5 and XBB.1.9.1) in the NB group maintained previous levels, but ratios to wild-type PRNT and fold changes exhibited significantly enhanced activity. The XBB.1.5 MonoV increased PRNT by 5.8-fold against XBB.1.5 and 6.6-fold against JN.1, showing stronger enhancement against subsequent epidemic strains than the bivalent vaccine. Conclusions Group immunity in the COVID-19 endemic era exhibited maintained SAb levels and adjusted neutralizing activities through BI and NB. The XBB.1.5 MonoV significantly enhanced neutralizing activity against the vaccine strain and robust immunity against the subsequent epidemic JN.1 strain.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":"68 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142752865","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}

Methods Serum samples at days 150, 365 and 545 post-dose were assayed for ADA titers. Samples with high ADA titers were characterized for their binding specificity to the Fab or the YTE portion of clesrovimab. RSV serum neutralization (SNA) titers were also measured on ADA+ and ADA- infants. Additionally, a D25 (site Ø) competitive ELISA was performed on ADA+ available samples to determine RSV exposure. Local surveillance data was used to ascertain RSV circulation during the trial. Results High ADA titers were observed in a minority of infants at days 365 and 545 for all doses tested. Additionally, all high titer ADA+ infants had ADA directed towards the YTE epitope of clesrovimab. Moreover, these infants demonstrated robust RSV-SNA and had D25 competitive antibodies suggesting an RSV exposure after day 150, coinciding with the epidemiological data.

We found that the macrophage metabolic landscape was similar regardless of the infecting Mtb isolate. Paralleling single-TLR activated macrophages, glycolysis inhibition during infection impaired IL-1β secretion. However, departing from TLR based models, in infected macrophages, IL-1β secretion was independent of mitochondrial metabolic changes and HIF-1α. Additionally, we found an unappreciated impact of a host metabolic inhibitor on the pathogen, and show that inflammasome activation and IL-1β production by macrophages require metabolically active bacteria. Our study highlights the potential confounding effect of host metabolic inhibitors on the pathogen and uncouples Mtb-inflammasome modulation from the host metabolic reprogramming.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684282","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}

Prior infection in a child is usually determined by RSV antibodies; however, in young children, persisting maternal immunoglobulin G antibodies can incorrectly indicate past RSV infection. We developed and evaluated 4 immunoglobulin A (IgA) antibody enzyme immunoassays (EIAs) with the RSV F, subgroup G (Ga or Gb proteins) or RSV lysate antigens to distinguish infection induced from persisting maternal RSV antibodies. Methods We tested the EIAs against 62 cord blood specimens (group A), 39 plasma specimens from infants not exposed to an RSV season (group B), 102 plasma specimens from infants with a documented RSV infection (group C), and 124 plasma specimens from infants exposed to their first RSV season but without a documented RSV infection (group D). Results Among the 2 negative control groups, no group A specimens and 1 of the group B specimens were positive in all 4 IgA EIAs, giving a specificity of 100% and 97%, respectively. The sensitivity of the F, Ga, Gb, and Lysate IgA EIAs were 88%, 31%, 26%, and 61%, respectively, for group C specimens. Forty-four percent of the 124 specimens in group D were positive in the RSV-F IgA EIA.

Following C. psittaci infection in HBE cells, we observed an elevated of HBE cells apoptosis, accompanied by upregulation of miR-124-3p levels. Mechanistically, we identified EIF3B as a novel target gene of miR-124-3p, supported by the inverse correlation of their mRNA expressions. MiR-124-3p inhibitors reduced apoptosis induced by C. psittaci, increased the replication of C. psittaci and inhibited the PI3K/AKT activated, whereas miR-124-3p mimics produced opposite effects, and transfection with EIF3B siRNA reversed the effects of miR-124-3p inhibitors.

The intestinal mucosa contains numerous target cells, and high levels of HIV-1 DNA persist in this compartment under ART. While CD4+ T cells are the best characterized reservoir of HIV-1, the role of long-lived intestinal macrophages in HIV-1 persistence on ART remains controversial. Methods We collected duodenal and colonic biopsies from 12 people living with HIV (PLWH) on suppressive ART, enrolled in the ARNS EP61 GALT study. Total, integrated, intact and defective HIV-1 proviruses were quantified from sorted T cells and monocytes/macrophages. HIV-1 env quasispecies were analyzed by single-molecule next-generation sequencing and env-pseudotyped viruses were constructed to assess macrophage versus T-tropism. Results Total HIV-1 DNA levels in intestinal T cells were significantly higher than those in monocytes/macrophages (P<0.0001). Unintegrated HIV-1 DNA was detected in one-third of T-cell and monocyte/macrophage-positive samples. Intact HIV-1 proviruses were detected using the intact proviral DNA assay in 4/16 T-cell samples and 1/6 monocyte/macrophage samples with detectable HIV-1 DNA. HIV-1 sequences were compartmentalized between intestinal monocytes/macrophages and T cells in some subjects. Phenotypic analysis of pseudotyped viruses expressing HIV-1 envelopes from colonic monocytes/macrophages revealed T-tropism rather than M-tropism. Conclusions Our results show that monocytes/macrophages from the intestinal mucosa of PLWH on ART can contain HIV-1 DNA, including intact or unintegrated forms, but at much lower levels than those found in T cells, and with some compartmentalization although they do not exhibit a specific macrophage tropism, raising the question of the mechanisms of infection involved.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672987","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}

Phylogenetic analysis was performed on complete RVFV genomes. Results Among 656 human participants, we detected RVFV RNA in four (0.6%), including one death with hepatic necrosis and other end-organ damage at autopsy. Humans infected with RVFV were enrolled from June through August 2018, and all resided in or near urban areas. Phylogenetic analysis of human and cattle RVFV sequences demonstrated that most clustered to lineage B, a lineage previously described in East Africa. A lineage E strain clustering with lineages in Angola was also identified in cattle.

We examined the impact and incidence of asymptomatic CSF-E in a Swedish HIV cohort. Methods Neuroasymptomatic people living with HIV (PLWH) who have been on ART for at least six months with suppressed plasma viral load were followed longitudinally. CSF-E was defined as either increased CSF HIV-1 RNA with concurrent plasma suppression or as CSF HIV-1 RNA exceeding that in plasma when both were quantifiable. Paired CSF and plasma were analyzed for HIV-1 RNA, neopterin, neurofilament light protein (NfL), white blood cell (WBC) count, and albumin ratio. Results Asymptomatic CSF-E (cut-off 50 copies/mL) was found in 4/173 PLWH (2%) and 5/449 samples (1%). The corresponding proportions were 8% of PLWH and 4% for samples using a 20 copies/mL cut-off for CSF HIV-1 RNA. CSF-E samples (cut-off 20 copies/mL) had a 25% higher geometric mean of CSF neopterin (P = .01) and 8% higher albumin ratio (P = .04) compared to samples without CSF-E. No differences were observed in CSF NfL levels (P = .8). The odds ratio for increased CSF WBC (≥ 3 cells/μL) in samples with CSF-E was 3.9 (P = .004), compared to samples without elevated CSF viral load. Conclusion Asymptomatic CSF-E was identified in only four (2%) PLWH, with no cases of continuous CSF-E observed. Increased CSF HIV-1 RNA was associated with biomarkers of CNS immune activation and blood-brain-barrier impairment, but not with biomarkers of neuronal injury.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":"159 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142601307","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}

This study assessed whether COVID-19 vaccination was protective against subsequent development of PCC in persons with predominantly mild initial infections during both Delta and Omicron variant predominance. Methods This study utilized a case-control design, nested within the HEROES-RECOVER cohort. Participants aged ≥18 years with PCR-confirmed SARS-CoV-2 infection between 6/28/2021 and 9/14/2022 were surveyed for PCC, defined by symptoms lasting >1 month after initial infection Cases were participants self-reporting PCC and controls were participants that did not self-report PCC. The exposure was mRNA COVID-19 vaccination (2 or 3 monovalent doses) versus no COVID-19 vaccination. Logistic regression was used to compare the odds of PCC among vaccinated and unvaccinated persons; additional analyses evaluating PCC subtypes were also performed. Results A total of 936 participants with documented SARS-CoV-2 infection were included; of these 23.6% (221) reported PCC and 83.3% (779) were vaccinated. Participants who received a 3rd COVID-19 monovalent mRNA dose prior to infection had lower odds of PCC-related gastrointestinal, neurological, and other symptoms compared to unvaccinated participants (aOR: 0.37; 95% CI: 0.16-0.85; aOR: 0.56; 95% CI: 0.32-0.97; aOR:0.48; 95% CI: 0.25-0.91). Conclusions COVID-19 vaccination protected against development of PCC among persons with mild infection during both Delta and Omicron variant predominance, supporting vaccination as an important tool for PCC prevention.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":"158 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142601397","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}
