研究目的: |
在现代医疗环境中,脓毒症患者常伴有肾功能衰竭,需要进行连续肾脏替代治疗(CRRT),复方磺胺甲噁唑(TMP/SMX)作为广谱抗菌药物,常用于治疗感染,由于当前临床实践和指南在TMP/SMX的剂量推荐上存在较大差异,而这些药物在CRRT过程中的清除率和体内浓度具有高度的变异性,且其在CRRT环境下的药代动力学和药效如何,目前研究尚不充分。本课题旨在通过PPK-PD-PG模型研究,揭示其在这一特殊人群中的药代动力学特性,优化治疗方案,以提高疗效和安全性。通过研究这一群体,我们能够更深入地理解复方磺胺甲噁唑在CRRT环境下的行为,为优化治疗提供科学依据。 本课题研究对象为接受CRRT的脓毒症患者,对所有受试者采集PK血样,检测样品中甲氧苄啶、磺胺甲噁唑及其代谢物磺胺甲噁唑-N-乙酰基和4-硝基磺胺甲噁唑的浓度,通过构建一系列生物分析方法(药动学血药浓度、药效学指标检测、相关基因型检测等),同时记录患者相关临床信息,建立患者数据库,观察患者的临床转归并分析其与药动学(PK)、药效学(PD)、药物基因组学(PG)之间的关系。基于收集的数据,构建一个包含群体药代动力学-药效学(PPK-PD)的联合模型,通过模拟预测不同条件下的药效和副作用。模型将通过内部和外部验证、敏感性分析等方法进行验证,确保其预测的准确性。最后基于模型,模拟出临床推荐的给药方案,以实现个体化治疗。这将有助于减少不必要的药物暴露,降低不良反应,提高患者生活质量。 总的来说,通过PPK-PD-PG模型,我们可以根据每个患者的具体情况,如肾功能、药物清除率等,预测最佳的药物剂量和给药方案,实现个体化治疗,显著提高治疗效果。 本研究旨在通过科学的方法,揭示磺胺甲噁唑在CRRT脓毒症患者群体中的药代动力学特性,为这类群体提供更优化的治疗方案以及为精准治疗和个体化医疗提供创新性的理论和实践支持,以期望填补相关领域的知识空白。 |

Objectives of Study: |
In modern healthcare settings, patients with sepsis are often associated with renal failure and require continuous renal replacement therapy (CRRT). trimethoprim/sulfamethoxazole (TMP/SMX) is commonly used as a broad-spectrum antimicrobial drug for the treatment of infections, and because current clinical practice and guidelines vary widely in the dosage recommendations of TMP/SMX, and the clearance and in vivo concentration of these drugs during CRRT have a high degree of variability, and their pharmacokinetics and efficacy in the CRRT setting are currently understudied. The aim of this study is to reveal the pharmacokinetic properties of PPK-PD-PG in this particular population through PPK-PD-PG modelling studies and to optimise the treatment regimen to improve efficacy and safety. By studying this group, we are able to gain a deeper understanding of the behaviour of cotrimoxazole in the setting of CRRT and provide a scientific basis for optimising treatment. The subjects of this study were sepsis patients undergoing CRRT. PK blood samples were collected from all subjects, and the concentrations of methotrexate, sulfamethoxazole and its metabolite sulfamethoxazole-N-acetyl and 4-nitrosulfamethoxazole were detected in the samples, and a series of bio-analytical methods were constructed (pharmacokinetic blood concentration, pharmacodynamic index test, relevant genotype test, etc.), and the patients' relevant clinical information, establish a patient database, observe the clinical regression of patients and analyse the relationship with pharmacokinetics (PK), pharmacodynamics (PD) and pharmacogenomics (PG). Based on the collected data, a joint model incorporating population pharmacokinetic-pharmacodynamic (PPK-PD) will be constructed to predict efficacy and side effects under different conditions through simulation. The model will be validated by internal and external validation and sensitivity analysis to ensure the accuracy of its prediction. Finally, based on the model, the clinically recommended dosing regimen will be simulated for individualised treatment. This will help reduce unnecessary drug exposure, decrease adverse effects and improve patient quality of life. Overall, with the PPK-PD-PG model, we can predict the optimal drug dosage and dosing regimen based on each patient's specific situation, such as renal function, drug clearance, etc., to achieve individualised treatment and significantly improve treatment outcomes. The aim of this study is to reveal the pharmacokinetic properties of sulfamethoxazole in the sepsis patient population of CRRT through scientific methods, to provide more optimal therapeutic regimens for this population as well as to provide innovative theoretical and practical support for precision therapy and individualised medicine, with the expectation of filling the knowledge gaps in the related fields. |
