Notably, genital warts (GW) are the first observable clinical outcome following infection by HPV-6/11, targeted by vaccination. We aim to gain knowledge of the incidence of GW in Sweden and evaluate its change throughout vaccination programs. Methods This ecological study used Swedish registers to obtain national population data and cases of genital warts from 2006-2018 in men and women aged 15-44. We used Poisson models to evaluate GW incidence change after vaccination in reference to a pre-vaccination period, stratified by age and sex. As well as, to estimate incidence change of GW in birth cohorts eligible for vaccination compared to a pre-vaccination cohort. Finally, we estimated GW cases averted in each vaccinated cohort. Results The incidence of GW decreased during periods following HPV vaccination. In 2016-2018, over a decade after vaccination availability, incidence decreased by 89% (95% CI 83-93), 73% (95% CI 71-75), 50% (95% CI 43-56) and 20% (95% CI 10-28) in women aged 15-19, 20-24, 25-29 and 30-34, respectively. A similar reduction was observable in men, although of lesser magnitude. We estimated 18,890 and 12,343 GW cases averted among vaccinated cohorts of women and men, respectively. Conclusions We report on population-level decreases of GW incidence in women and men following increased vaccination coverage. Cohorts eligible for school-based vaccination recorded the largest decrease in GW incidence in Sweden to date. For the period under study, decreases among men could be attributed to herd effects.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143056963","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 OLT recipients admitted to the post-transplant ICU between June 2021 and May 2024 having documented Gram-negative infections treated with targeted therapy continuous infusion (CI) beta-lactams, and undergoing therapeutic drug monitoring (TDM)-guided beta-lactam dosing adjustment in the first 72 hours were prospectively enrolled. Free steady-state concentrations (fCss) of beta-lactams (BL) and/or of beta-lactamase inhibitors (BLI) were calculated, and aggressive PK/PD target attainment was measured. Multivariate logistic regression analyses were performed for testing independent variables associated with 30-day resistance occurrence. Results Fifty critical OLT recipients were treated with CI beta-lactam in mono- (n=34) or in combination (n=16) therapy for documented Gram-negative infections (46% hospital-acquired/ventilator-associated pneumonia). Combination therapy was selected more frequently for treating intraabdominal infections (P=0.03) and was associated with lower attainment of aggressive PK/PD target (P=0.03). No significant difference in clinical/microbiological outcome emerged between mono- and combination therapy. Four patients (8.0%) developed 30-day resistance occurrence. At multivariate analysis, failure in attaining an aggressive beta-lactam PK/PD target emerged as the only independent predictor of 30-day resistance development (OR 14.33; 95% CI 1.46-140.53; P=0.02).

This is a particularly important immune checkpoint in the case of emerging infections against which most of the population does not have preexisting antibody immunity. In this study, we sought to test whether antibody-based delivery of Ebola virus (EBOV) antigens to dendritic cells could be used as a vaccination strategy against Ebola virus disease. Our approach was to use antibodies targeting the endocytic receptor DEC-205 present in murine and human dendritic cells, to deliver the EBOV nucleoprotein or the model antigen ovalbumin (OVA). Our findings indicate that DEC-205 targeting stimulated antigen-specific T-cell responses in mice, which resulted in protection from EBOV or recombinant EBOV-OVA challenge. An added value of this strategy was the generation of resident memory T cells. We propose that dendritic cell targeting could be used to improve T-cell responses against filoviruses, a strategy that may complement current vaccination strategies.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030842","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 We developed a computational simulation model representing the clinical course, the health effects, and the associated costs of a person with Long COVID. Results Simulations show that the average total cost of a Long COVID case can range from $5,084-$11,646 (assuming symptoms only last 1 year) with 92.5%-95.2% of these costs being productivity losses. Therefore, the current number of Long COVID cases could end up costing society at least $2.01-$6.56 billion, employers at least $1.99-$6.49 billion in productivity losses, and third-party payers $21-68.5 million annually (6%-20% probability of developing Long COVID). These cases would accrue 35,808-121,259 QALYs lost and 13,484-45,468 DALYs. Moreover, each year, there may be an additional $698.5 million in total costs, 14,685 QALYs lost, and 5,628 DALYs, if the incidence of COVID is 100 per 10,000 persons (similar to that seen in 2023). Every 10-point increase in COVID incidence results in an additional $365 million in total costs, 5,070 QALYs lost, and 1,900 DALYs each year. Conclusion The current health and economic burden of Long COVID may already exceed that of a number of other chronic disease and will continue to grow each year as there are more and more COVID-19 cases. This could be a significant drain on businesses, third party payers, the healthcare system, and all of society.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":"50 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020432","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}

Given that cytokine, including Interleukin-6 (IL-6), play a critical role in immune-mediated organ injury in patients with severe COVID-19, we hypothesized that cytokines may also contribute to the pathogenesis of severe pneumonia after allo-HSCT. This study aimed to investigate the role of IL-6 in severe pneumonia post-allo-HSCT and explore its underlying mechanism. Methods Serum cytokine levels were prospectively measured in patients with severe and non-severe pneumonia following allo-HSCT. A mouse model of acute lung injury (ALI) and in vitro experiment using primary murine pulmonary microvascular endothelial cells (PMVECs) were conducted to assess the effects of IL-6 blockade, the mechanism of IL-6 in ALI, and immune-induced ALI. Results Serum IL-6 and sIL-6R levels were higher in the severe pneumonia group than in the non-severe group and were associated with disease progression. In a mouse model, preventive IL-6 blockade reduced ALI and improved survival. In vitro, the IL-6 trans-signaling complex caused more severe damage to mouse PMVECs than the classical signaling pathway. Soluble glycoprotein 130 and ruxolitinib effectively blocked the JAK1/STAT3 pathway activated by IL-6 trans-signaling in mouse PMVECs and reduced downstream inflammatory responses. Conclusions IL-6 levels were elevated in patients with severe pneumonia after allo-HSCT and were linked to disease progression. This injury may be driven by the IL-6/sIL-6R/JAK1/STAT3 pathway. This preliminary study suggests that targeting the IL-6 trans-signaling pathway may be a promising therapeutic approach for severe pneumonia/ALI following allo-HSCT.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":"131 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142991333","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 aim to assess mp-tNGS in bronchoalveolar lavage fluid (BALF) for Aspergillus detection in suspected IPA patients, and to provide a reliable basis for initiating antifungal therapy without microbiological or histopathological evidence. Methods We prospectively enrolled a cohort of consecutive patients suspected of IPA, all of them had undergone serum/BALF galactomannan antigen (GM), BALF mp-tNGS, and traditional tests (direct smear and culture of respiratory specimens), EORTC/MSGERC and FUDICU criteria were used for IPA diagnosis. Results Thirty-two patients were diagnosed with IPA and 42 with non-IPA. Compared with the final diagnosis, the sensitivity of BALF mp-tNGS was 87.5%, while the sensitivity of traditional tests, serum GM and BALF GM assay was 43.8%, 21.9%, and 62.5%, respectively; the specificity of BALF mp-tNGS was 90.5%, which was similar to traditional tests.

Current therapeutic approaches encounter a critical limitation, as conventional antibiotic treatment is contraindicated due to its propensity to trigger bacterial SOS response and subsequently enhance Stx production, which increases the likelihood of developing HUS in antibiotic-treated patients. The lack of effective, safe therapeutic options has created an urgent need for alternative treatment strategies for STEC infections. This study investigates the therapeutic potential of virulent bacteriophages (phages) against STEC O157:H7. Our findings demonstrate that these phages effectively reduce STEC populations to levels comparable to ciprofloxacin treatment, while crucially avoiding the induction of SOS response and subsequent enhancement of Stx production. This is a significant advantage over conventional antibiotics which increase Stx levels. Furthermore, these phages exhibited broad-spectrum antimicrobial activity against multiple clinical STEC isolates without triggering toxin expression. The capability of virulent phages to effectively control STEC without enhancing toxin production represents a promising therapeutic strategy that combines antimicrobial efficacy with safety considerations. These characteristics indicate that virulent phages represent a potential solution to address the current therapeutic challenges in STEC infections, particularly in mitigating the risk of HUS development in infected patients.","PeriodicalId":501010,"journal":{"name":"The Journal of Infectious Diseases","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142989946","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}
