The mechanisms of the organ-specific manifestation are not completely understood. To analyze the role of glomerular and tubular damage in kidney injury induced by HFRS, we measured specific markers in urine samples of patients with acute Puumala virus (PUUV) infection and determined their correlation with disease severity. Levels of α1-microglobulin (α1-MG) and kidney injury molecule 1 (KIM-1), which is expressed by injured tubular epithelial cells, were measured to detect tubular dysfunction and injury. Immunoglobulin G (IgG) and the podocyte specific protein nephrin served as markers for glomerular injury. All four markers were elevated on admission. Markers of glomerular injury, IgG and nephrin, correlated with markers of disease severity such as length of hospitalization, serum creatinine, and proteinuria. In contrast, tubular injury did not correlate with these severity markers. Our results demonstrate that hantavirus infection induces both glomerular and tubular injury early in the clinical course. However, the glomerular dysfunction and podocyte injury seem to contribute directly to disease severity and to play a more central role in HFRS pathogenicity than direct damage to tubular epithelial cells.</p>","PeriodicalId":19758,"journal":{"name":"Pathogens","volume":null,"pages":null},"PeriodicalIF":3.3,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11356809/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142110600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We retrospectively analysed 1781 consecutive patients admitted to a single tertiary academic institution in Singapore with COVID-19 infection from February 2020 to October 2021. A total of 161 (9.0%) patients had hyponatremia. These patients were significantly older, with more co-morbidities and more likely to be admitted during the Delta wave (2021).

Hyponatremia remained independently associated with adverse outcomes after adjusting for age, lack of medical co-morbidities, vaccination status, year of admission, CRP, LDH, and ferritin.

Without antimicrobial treatment, this disease has a mortality rate of up to 88% in infected patients. The most common method for diagnosing <i>B. bacilliformis</i> infection is serological testing. However, the current serological assays are limited in sensitivity and specificity, underscoring the need for the development of novel and more accurate diagnostic tools. Recombinant proteins have emerged as promising candidates to improve the serological diagnosis of Carrion's disease. So, we focused on evaluating the conditions for producing two previously predicted proteins of <i>B. bacilliformis</i> using the baculovirus-insect cell expression system, mainly the flashBAC ULTRA technology. We assessed various parameters to identify the conditions that yield the highest protein production, including cell lines, temperature, and hours post-infection (hpi). The results showed that the expression conditions for achieving the highest yields of the Prot_689 and Prot_504 proteins were obtained using High Five™ cells at 21 °C and harvesting at 120 hpi. Subsequently, the seroreactivity of recombinant proteins was evaluated using positive sera from patients diagnosed with Carrion's disease. These findings offer valuable insights into the production conditions of <i>B. bacilliformis</i> recombinant proteins using the baculovirus system, which could significantly contribute to developing more precise diagnostic tools for Carrion's disease. Therefore, this research provides implications for improving diagnostics and potentially developing therapeutic strategies.</p>","PeriodicalId":19758,"journal":{"name":"Pathogens","volume":null,"pages":null},"PeriodicalIF":3.3,"publicationDate":"2024-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11357310/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142116988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prolonged and widespread use of insecticides has led to the development of mosquito resistance to these insecticides. The gut microbiota is considered the master of host development and physiology; it influences mosquito biology, disease pathogen transmission, and resistance to insecticides. Understanding the role and mechanisms of mosquito gut microbiota in mosquito insecticide resistance is useful for developing new strategies for tackling mosquito insecticide resistance. We searched online databases, including PubMed, MEDLINE, SciELO, Web of Science, and the Chinese Science Citation Database. We searched all terms, including microbiota and mosquitoes, or any specific genera or species of mosquitoes. We reviewed the relationships between microbiota and mosquito growth, development, survival, reproduction, and disease pathogen transmission, as well as the interactions between microbiota and mosquito insecticide resistance. Overall, 429 studies were included in this review after filtering 8139 search results. Mosquito gut microbiota show a complex community structure with rich species diversity, dynamic changes in the species composition over time (season) and across space (environmental setting), and variation among mosquito species and mosquito developmental stages (larval vs. adult). The community composition of the microbiota plays profound roles in mosquito development, survival, and reproduction. There was a reciprocal interaction between the mosquito midgut microbiota and virus infection in mosquitoes. <i>Wolbachia</i>, <i>Asaia</i>, and <i>Serratia</i> are the three most studied bacteria that influence disease pathogen transmission. The insecticide resistance or exposure led to the enrichment or reduction in certain microorganisms in the resistant mosquitoes while enhancing the abundance of other microorganisms in insect-susceptible mosquitoes, and they involved many different species/genera/families of microorganisms. Conversely, microbiota can promote insecticide resistance in their hosts by isolating and degrading insecticidal compounds or altering the expression of host genes and metabolic detoxification enzymes. Currently, knowledge is scarce about the community structure of mosquito gut microbiota and its functionality in relation to mosquito pathogen transmission and insecticide resistance. The new multi-omics techniques should be adopted to find the links among environment, mosquito, and host and bring mosquito microbiota studies to the next level.</p>","PeriodicalId":19758,"journal":{"name":"Pathogens","volume":null,"pages":null},"PeriodicalIF":3.3,"publicationDate":"2024-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11357333/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142110610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
