Expanding flavivirus co-circulation and vaccination complicate testing. We evaluate the accuracy of a common dengue virus serological assay, examine immunity to non-dengue flaviviruses as a contributor to decreased performance, and assess whether alternative cut points may improve assay performance. Methods Children (n = 770) aged 2–9 years in Kampong Speu, Cambodia were enrolled in a prospective longitudinal study, and PanBio indirect dengue virus immunoglobulin G (IgG) enzyme-linked immunosorbent assay (ELISA) was performed. Plaque reduction neutralization tests (PRNTs) using dengue viruses were performed on a subset to assess the accuracy of the IgG ELISA, and PRNTs with Zika, Japanese encephalitis, and West Nile viruses evaluated immunity to non-dengue flaviviruses. Receiver operating curve analysis identified an alternative cut point to improve IgG ELISA accuracy. Results The dengue IgG ELISA had a lower specificity than previously reported (58% vs 93%–100%). Of those with false-positive IgG results, 46% had detectable neutralizing antibodies against other flaviviruses including 14% against West Nile virus. A higher IgG cut point improved the test accuracy in this population. Conclusions Physicians and public health authorities should be alert for West Nile in Cambodia. Immunity to non-dengue flaviviruses can impact dengue surveillance.

However, it remains unknown if the quality and/or quantity of the monocyte reservoir contributes to cognition in vsWWH. Methods 62 vsWWH(mean age=56.1, SD=7.1; 93% Black, non-Hispanic; all HIV RNA <250 copies/mL) completed a cognitive test battery, blood draw, and whole blood immunophenotyping. Monocytes and CD4 T cells were isolated from a subset of 53 participants and the HIV reservoir was assessed using cell specific Intact Proviral DNA Assays(IPDA). Demographically-adjusted z-scores were calculated for each outcome using data from participants without HIV in the Women’s Interagency HIV Study. Cognitive outcomes of interest included domain-specific and global z-scores. Results Thirty-Eight percent of vsWWH had detectable intact HIV genomes in monocytes(median=21.5 copies/million). Higher levels of intact HIV genomes per million monocytes were associated with poorer verbal memory(delayed recall: r=0.55, P=0.01; recognition: r=0.46, P=0.04), fine motor skills(r=0.50, P=0.03), and global function(r=0.47, P=0.04). Higher levels of intact HIV genomes in monocytes were associated with percent intermediate monocytes(r=0.60, P=0.008), and the ratio of intact per intermediate monocyte was associated with worse memory(r=-0.59, P=0.008). There were no associations between CD4 reservoir and cognition. Discussion The number of intact HIV genomes per million monocytes were related to poorer cognition and the percentage of intermediate monocytes. These findings suggest that the presence of HIV genomes in general do not relate to cognitive complications, but intact, and therefore potentially replication-competent HIV, may contribute to cognitive complications in vsWWH.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142245263","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}

We aimed to study the impact of girls-only HPV vaccination on genital HPV prevalence among young adults. Methods and findings PASSYON is a biennial repeated cross-sectional study (2009-21) among sexual health clinic clients aged 16-24 years old. Questionnaires elicited data on demographics, sexual behaviour and HPV vaccination status. Genital samples were collected and analysed using a PCR-based assay (SPF10-LiPA25). Type-specific prevalence trends of 12 high-risk (hr) genotypes were analysed as the adjusted average annual change (aAAC), estimated using Poisson GEE models. The relation between aAAC and phylogenetic distance to HPV-16/18 was assessed by means of regression and rank correlation analysis. Questionnaires and genital samples were collected from 8,889 females and 3,300 heterosexual males (HM). 4,829 females reported to be unvaccinated (54·3%). Among females (irrespective of vaccination status), prevalences of HPV-16/18/31/33/35/45 decreased significantly over time. Increasing trends were observed for HPV-39/52/56. Among both HM and unvaccinated females HPV-16/18 prevalence significantly declined, as did HPV-31 among HM. In contrast, HPV-52/58 increased significantly among HM and unvaccinated females. The type-specific aAAC correlated well with the phylogenetic distance to HPV-16/18. Conclusions During twelve years girls-only bivalent HPV vaccination in the Netherlands, decreasing trends of the vaccine types and cross-protected types were observed among females. Herd protection of vaccine-types was observed for HM and unvaccinated females, and one cross-protected type for HM. Increasing prevalence trends of HPV types with large phylogenetic distance to the vaccine types might indicate type-replacement.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142233438","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}

However, there is limited consensus about the complementary role of mucosal immunity in disease progression and how to evaluate immunogenicity of mucosal vaccines. This study investigated the role of oral mucosal antibody responses in viral clearance and COVID-19 symptom duration. Methods Participants with PCR-confirmed SARS-CoV-2 infection provided oral fluid for testing with SARS-CoV-2 antibody multiplex assays, nasal swabs for RT-PCR and symptom information at up to eight follow-ups from April 2020 to February 2022. Results High and moderate oral fluid anti-spike (S) secretory IgA (SIgA) post infection was associated with significantly faster viral clearance and symptom resolution across age groups with effect sizes equivalent to having COVID-19 vaccine immunity at the time of infection. Those with high and moderate anti-S SIgA cleared the virus 14 days (95% CI: 10-18) and recovered 9-10 days (95% CI: 6-14) earlier. Delayed and higher anti-S IgG was associated with significantly longer time to clearance and recovery. Experiencing symptoms longer than four weeks was associated with lower anti-RBD SIgA 15-30 days after infection onset (p<0.001). Conclusion Robust mucosal SIgA early post infection appears to support faster clearance of SARS-CoV-2 and recovery from COVID-19 symptoms. This research underscores the importance of harmonizing mucosal immune response assays to evaluate new mucosal vaccines.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142233270","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}

Blood was also collected for centralized testing using established antibody assays (GenScript cPass). A nested case-control study assessed if POC tests conducted on stored specimens were predictive of time to sustained recovery, mortality, and a composite safety outcome. Results While both POC tests exhibited moderate agreement with the GenScript assay (both agreeing with 89% of antibody determinations), they were significantly different from the GenScript assay. Treating the GenScript assay as the gold standard, the LumiraDX assay had 99.5% sensitivity and 58.1% specificity while the RightSign assay had 89.5% sensitivity and 84.0% specificity. The LumiraDX assay frequently gave indeterminant results. Both tests were significantly associated with clinical outcomes.

Methods We quantified IPD cases during 2016-2022. Employing genomic-based characterization of IPD isolates, we identified serotype-switch variants. Recombinational analyses were used to identify the genetic donor and recipient strains that generated a serotype 4 progeny strain. We performed phylogenetic analyses of the serotype 4 progeny and serotype 12F genetic recipient to determine genetic distances. Results We identified 30 inter-related (0-21 nucleotide differences) IPD isolates recovered during 2022–2023, corresponding to a serotype 4 capsular-switch variant. This strain arose through a multi-fragment recombination event between serotype 4/ST10172 and serotype 12F/ST220 parental strains. Twenty-five of the 30 cases occurred within Oregon. Of 29 cases with known residence status, 16 occurred in AEH. Variant emergence coincided with a 2.6-fold increase (57 to 148) of cases caused by the serotype 4/ST10172 donor lineage in 2022 compared to 2019 and its first appearance in Oregon. Most serotypes showed sequential increases of AEH IPD/all IPD ratios during 2016-2022 (for all serotypes combined, 247/2198, 11.2% during 2022 compared to 405/5317, 7.6% for 2018-2019, p<0.001). Serotypes 4 and 12F each caused more IPD than any other serotypes in AEH during 2020-2022 (207 combined reported cases primarily in 4 western states accounting for 38% of IPD in AEH).
