Lymphocytes were isolated into T, B, and natural killer cells using magnetic bead sorting, followed by individual polymerase chain reaction testing. Receiver operating characteristic curve analysis identified subtype-specific cutoffs for EBV-HLH prediction. Kaplan-Meier and Cox regression analyses assessed viral load-HLH risk associations.

Methods Participants ages ≥18 years, assigned female sex at birth and reporting TGM or non-binary identity, interested in starting injectable testosterone, demonstrating optimal vaginal microbiota, with no current STI(s) were enrolled. Participants self-collected daily vaginal specimens for 7 days prior to testosterone initiation and 90 days thereafter for vaginal Gram staining and 16S rRNA gene sequencing.

Methods The study included biobanked CSF from 18 CoV-Enceph, 4 subjects with COVID-19 without encephalitis (CoV), 21 non-COVID-related encephalitis (Enceph), and 21 neurologically healthy controls. Participants underwent a standardized assessment for encephalitis. A large subset of samples underwent an extended panel of CSF neuronal, glial and inflammatory biomarkers. ACE2 and TMPRSS2 species were determined in the CSF by western blotting. Results ACE2 was present in CSF as several species, full-length forms, and two cleaved fragments of 80 and 85 kDa. CoV-Enceph patients displayed increased CSF levels of full-length species, as well as the 80 kDa fragment, but not the alternative 85 kDa fragment, compared with controls and Enceph patients, characterized by increases of both fragments. Furthermore, TMPRSS2 was increased in the CSF of Enceph patients compared with controls, but not in CoV-Enceph patients. The CoV patients without encephalitis displayed unaltered CSF levels of ACE2 and TMPRSS2 species. Conclusions Patients suffering from encephalitis displayed an overall increase in CSF ACE2 probably as a consequence of brain inflammation. The increase of the shortest ACE2 fragment only in CoV-Enceph patients may reflect the enhanced cleavage of the receptor triggered by SARS-CoV-2, thus serving to monitor brain penetrance of the virus associated with the rare encephalitis complication. TMPRSS2 changes in the CSF appeared related with inflammation, but not with SARS-CoV-2 infection.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546226","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}

Participants with viremia at baseline had lower SARS-CoV-2 binding antibody levels and higher pro-inflammatory cytokine levels, including IP-10 (CXCL10), TNF-α, calprotectin, and CRP.

Preventative approaches to protect infants from GBS infection are needed. Methods In this phase 2b, randomized study, healthy nonpregnant 18−49-year-old females were randomized 1:1:1 to receive the investigational 6-valent GBS polysaccharide conjugate vaccine (GBS6) and concomitant Tdap (GBS6+Tdap), GBS6 and placebo (GBS6+placebo), or Tdap and placebo (Tdap+placebo). Primary safety endpoints included reactogenicity events within 7 days and adverse events (AEs) through 1 month after vaccination. Primary immunogenicity objectives were to describe immune responses induced by GBS6+Tdap versus Tdap+placebo and versus GBS6+placebo for pertussis, tetanus, and diphtheria Tdap antigens and the 6 GBS6 antigens. Results Overall, 304 participants received study vaccination. Most reactogenicity events were mild or moderate in severity and balanced across vaccine groups. Frequency of AEs was ≤8.1% across vaccine groups. One-month after vaccination, the proportion of participants achieving antibody concentrations ≥0.1 IU/mL, for tetanus and diphtheria antigens was 100% in both GBS6+Tdap and Tdap+placebo groups. Immune responses to pertussis antigens were lower in the GBS6+Tdap group compared to the Tdap+placebo group, with geometric mean ratios <0.6. No consistent effect on immune responses against each of the GBS6 serotypes after concomitant administration with Tdap was observed. Conclusions GBS6 and Tdap administered concomitantly and alone were safe and well tolerated in healthy nonpregnant individuals.

In October-2019, the Melbourne Sexual Health Centre changed routine treatment of all chlamydia contacts to selective treatment, reserving same-day treatment for those testing positive, unless patients presented with symptoms or with specific reasons. Methods We conducted a before-and-after study among chlamydia contacts at MSHC by comparing 12 months before the ‘routine treatment period’ (December-2018 to October-2019) and after the ‘selective treatment period’ (November-2019 to December-2020). Results Of the 2843 chlamydia contacts included in the analysis, chlamydia positivity was 31.9% (907/2843). The proportion of contacts who received treatment before test results decreased from 91% (1380/1515) to 56% (739/1328) (p<0.0001). We reviewed 232 of the 739 chlamydia contacts in the selective period to determine reasons for treatment, 41.4% (96/232) were treated due to the presence of symptoms. The proportion of those who received treatment and later tested positive did not change between the two periods (35% [482/1380] vs. 34% [253/739], p=0.750). However, the proportion of contacts who received unnecessary treatment (treated but tested negative) did not change between the two periods (65% [898/1380] vs. 66% [486/739], p=0.750).

Currently, only a few patients achieve this with treatment. Host differences must be influential. Solute Carrier Family 22 Member 1 (SLC22A1), encoding organic cation transporter 1, is expressed in the liver and mediates substance transport of hepatocytes. The association between SLC22A1 and CHB has not been determined. Our objective was to elucidate this association. Methods RNA-seq was performed to explore the changes caused by HBV and SLC22A1. SLC22A1 of plasma and liver biopsies in healthy controls and CHB were measured by ELISA and immunohistochemistry. Plasma from 200 patients with CHB (120 uncured, 80 cured) completing the pegIFNα-based treatment was collected at baseline, 12 and 24 weeks of treatment and measured with ELISA. Results SLC22A1 was downregulated by HBV, as indicated by comparing SLC22A1 of hepG2 and HBV-expression hepG2 cells (hepG2 transfected with pHBV1.3, hepG2.2.15 or hepG2-NTCP infected by HBV) and of both liver and plasma in CHB and healthy volunteers. Plasma SLC22A1 in cured group rose dynamically but not in uncured group. Plasma SLC22A1 at 24 weeks was predictive of functional cure (AUC=0.887) and better when combined with HBsAg at 24 weeks (AUC=0.925). Vitro experiments regarding overexpression of SLC22A1 in hepG2.2.15 demonstrated that HBsAg and HBeAg were inhibited by SLC22A1 through JAK/STAT pathway activation, consistent with transcriptome sequencing results.
