Normal saline pre-infusion is a recommended measure to reduce the risk of nephrotoxicity in patients receiving AmBd. Objectives To examine the effect of different normal saline solution (NSS) pre-infusion doses, and other potential risk factors, on the development of acute kidney injury (AKI) in patients with invasive fungal infection receiving AmBd. Methods Adult patients with invasive fungal infections who received intravenous AmBd were included in this retrospective study. Doses of the normal saline pre-infusion were adjusted to the body weight (NSS/BW) and the daily dose of amphotericin B (NSS/AmBd). Kaplan–Meier survival analysis was used to estimate 14 d AKI-free survival rates, and the log-rank test was used to compare AKI-free survivals between groups. Results The present study included 60 patients; 31 patients developed AKI during the AmBd therapy. The overall 14 d AKI-free survival was 48.3%. NSS/AmBd, but not NSS/BW, was associated with AKI-free survival in patients receiving AmBd: the higher the NSS/AmBd, the higher the AKI-free survival. Gender, baseline blood urea nitrogen (BUN), and baseline plasma bicarbonate (Bicarb) also affected AKI-free survival. Female gender, higher BUN, and lower Bicarb were associated with higher AKI-free survival. Conclusions The present study suggests that low NSS/AmBd, male gender, low BUN, and high Bicarb are risk factors for AmBd-associated AKI. Excluding gender, these risk factors are potentially modifiable and would guide tailoring appropriate preventive measures for AmBd-associated AKI.","PeriodicalId":8501,"journal":{"name":"Asian Biomedicine","volume":"13 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139072192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hemorrhagic transformation (HT), a severe complication of AIS, is influenced by platelet-induced inflammation and lymphocyte levels. Objective To measure the predictive value of platelet-to-lymphocyte ratio (PLR) in the occurrence of HT in young AIS patients. Methods Data of young AIS patients (n = 157) admitted to the hospital for the first time were retrospectively collected. The patients were divided into HT (63 patients) and non-HT groups (94 patients) on the basis of whether HT had occurred after admission. The National Institute of Health stroke scale (NIHSS) score was used to determine the severity of clinical symptoms. The relationship between PLR and HT and NIHSS scores was analyzed to evaluate the predictive value of PLR in the occurrence of HT using receiver operating characteristic (ROC) and area under the curve (AUC). Results Multivariate analysis showed that PLR and NIHSS are independent risk factors of HT. The PLR value of the observation group was positively associated with the NIHSS score (<jats:italic>r</jats:italic> = 0.8075, <jats:italic>P</jats:italic> &lt; 0.0001). According to the PLR prediction about the occurrence of HT, an AUC of 0.713 (95% CI, 0.652–0.781), a cut-off value of 109.073, and a sensitivity and specificity of 0.806 and 0.674, respectively, were obtained. Conclusions PLR value can predict the possibility of HT in young AIS patients to a certain extent. To take effective measures to prevent HT in advance has crucial clinical significance according to PLR value.","PeriodicalId":8501,"journal":{"name":"Asian Biomedicine","volume":"97 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139068180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
