The aim of this study was to investigate the impact of changes in platelet trajectories on the clinical prognosis of sepsis. Methods: This study was a retrospective analysis using data from the Medical Information Mart for Intensive Care IV database. Patients with sepsis were identified from the database, and their platelet trajectories were categorized into four distinct models based on the changes in platelet counts over a period of 14 days after diagnosis of sepsis. The effect of these trajectories on patient prognosis was subsequently evaluated. Results: A total of 15,250 patients with sepsis were included to construct a model, and the following four distinct platelet count trajectories were identified: normal platelet levels (phenotype 1); persistently low platelet levels (phenotype 2); gradually increasing platelet levels exceeding the normal range (phenotype 3); and consistently significantly elevated platelet levels (phenotype 4). Statistically significant differences were found in the 28-day mortality, in-hospital mortality, and 90-day mortality among the four phenotypes. Multivariate regression analysis showed that compared to the group with normal platelet levels (phenotype 1), the group with persistently low platelet levels (phenotype 2) had higher in-hospital mortality (odds ratio [OR] = 1.34, 95% confidence interval [CI]: 1.16-1.54), 28-day mortality (OR = 1.69, 95% CI: 1.47-1.94), and 90-day mortality (OR = 1.50, 95% CI: 1.32-1.69). There was no difference in in-hospital mortality between phenotypes 3 and 4 compared to phenotype 1, although phenotype 4 showed an increase in 28-day mortality ( P < 0.05), and phenotype 3 showed a decreasing trend in 90-day mortality ( P < 0.05). The results of inverse probability weighting adjusted by regression were basically consistent with the above findings, except that there was no statistical difference in 28-day mortality between phenotype 4 and phenotype 1. In the subgroups based on age, weight, and antiplatelet drugs or therapies, there was an interaction between platelet levels and these factors. Conclusions: In patients with sepsis, a decrease in platelet count is associated with increased mortality, while a moderate increase in platelet count can reduce 90-day mortality. However, for patients with persistently elevated platelet counts, caution is advised when using antiplatelet drugs or therapies, as it may increase mortality.</p>","PeriodicalId":21667,"journal":{"name":"SHOCK","volume":" ","pages":"371-378"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142507126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AKI is associated with an increased risk of death, prolonged hospital stays, and subsequent transition to chronic kidney disease. Catecholamines have historically been used as the first-line vasopressors for vasodilatory shock; however, they may adversely affect renal function and recovery. Objectives: To compare the effects of catecholamine and noncatecholamine vasopressors on AKI risk and recovery in preclinical and clinical studies of vasodilatory shock. Methods: MEDLINE, Embase, and Cochrane Central Register of Controlled Trials were systematically searched to identify studies reporting renal outcomes associated with catecholamine (norepinephrine, epinephrine, metaraminol, phenylephrine, dopamine) and noncatecholamine vasopressors (vasopressin, angiotensin II), in preclinical models or adult cohorts of vasodilatory shock. Two independent reviewers screened studies and extracted data using a prespecified form for qualitative synthesis and risk of bias assessment. Results: Of 3,504 citations, 90 studies were eligible for inclusion: 41 preclinical studies, 17 nonrandomized clinical studies, 28 randomized clinical studies, and 4 post-hoc analyses. Risk of bias was generally low in preclinical studies and low to moderate in clinical studies. In preclinical studies, catecholamine vasopressors exacerbated medullary hypoxia and intrarenal inflammation compared to noncatecholamine vasopressors. In clinical studies, catecholamines were associated with higher serum creatinine, lower urine output, and increased requirements for renal replacement therapy compared to noncatecholamine vasopressors. In patients on high-dose catecholamines, adjunctive angiotensin II was associated with improved renal replacement therapy liberation. Conclusion: Preclinical and clinical studies suggest that noncatecholamine vasopressors may confer renal benefits compared to catecholamine vasopressors. These hypothesis-generating observations suggest the need for comparative studies focused on renal outcomes.

In addition to replicative stress resulting from telomeric loss, recent studies have identified multiple factors contributing to cell cycle arrest. Furthermore, our understanding of pathways associated with cellular senescence, such as CD47-mediated suppression of efferocytosis, has expanded. However, beyond in vitro experiments, the impact of cell stress during complex systemic illnesses, including sepsis, remains poorly understood. Consequently, we conducted an investigation into molecular alterations related to senescence-associated pulmonary mechanisms during experimental nonpulmonary sepsis. Methods: Male C57BL/6JRj mice were anesthetized and subjected to either control conditions (sham) or cecal ligation and puncture (CLP) to induce sepsis. Twenty-four hours or 7 d after CLP, animals were killed, and blood, bronchoalveolar fluids, and lungs were harvested and analyzed for morphological and biochemical changes. Results: Histological damage in pulmonary tissue, as well as increases in plasma levels of surfactant protein D, indicated development of alveolar-focused acute lung injury after CLP. Additionally, we observed a significant upregulation of the CD47-QPCTL-SHP-1 axis in lungs of septic mice. Whereas the expression of p16, a marker primarily indicating manifested forms of senescence, was decreased after CLP, the early marker of cellular senescence, p21, was increased in the lungs during sepsis. Later, at 7 d after CLP, pulmonary expression of CD47 and QPCTL-1 was decreased, whereas SHP-1 was significantly enhanced.

Among these interventions, there is a clinical practice heterogeneity regarding use of fluids in this setting. The optimal fluid resuscitation strategy remains controversial. This systematic review aimed to summarize the current knowledge regarding type, dosing, and safety of fluid therapy during and after CPR in animal models and human studies. Methods: A systematic search of the literature within PubMed and Embase was conducted from database inception to June 2024. Preclinical and clinical studies involving adult patients with nontraumatic cardiac arrest describing fluid resuscitation strategies and reporting at least one outcome of interest were included: achievement of return of spontaneous circulation, survival to hospital admission or discharge, incidence of acute kidney injury and neurological outcome. Studies assessing intra-arrest bicarbonate buffer therapy and/or using cold fluid infusions to induce hypothermia were excluded. Results: Twenty-nine studies met inclusion criteria, including 10 clinical studies and 19 animal models. The effects of fluid therapy during CPR are underexplored in clinical research. Hypertonic saline therapy has emerged as an alternative resuscitative fluid during CPR in animal models. In postresuscitation setting, balanced crystalloids have been increasingly assessed. There are no clinical studies investigating the impact of early goal directed fluid resuscitation on outcomes in particular shock resolution and neurological recovery. Conclusions: There is a call for clinical evidence to assess the efficacy and safety of fluid resuscitation during CPR, to define the place of hypertonic saline therapy during and after resuscitation and finally to implement early goal-directed fluid therapy as a tailored intervention of the postarrest care bundle.
