研究目的: |
建立并验证一种检测血浆中依拉环素和奥马环素浓度的HPLC-MS/MS检测方法;建立并验证依拉环素和奥马环素PopPK模型和PBPK模型;利用上述模型结合蒙特卡洛模拟(Monte Carlo Simulation,MCS)得出依拉环素和奥马环素对不同耐药病原菌的PKPD靶值;利用代谢组学方法探究依拉环素和奥马环素在耐药菌感染患者中的作用机制。 |

|
Objectives of Study: |
Establish and validate an HPLC-MS/MS method for the determination of eravacycline and omadacycline concentrations in plasma; establish and validate population pharmacokinetic (PopPK) and physiologically based pharmacokinetic (PBPK) models for eravacycline and omadacycline; integrate these models with Monte Carlo simulation (MCS) to derive the PK/PD targets of eravacycline and omadacycline against different drug-resistant pathogens; and explore the mechanisms of action of eravacycline and omadacycline in patients with drug-resistant bacterial infections using metabolomics approaches. |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
A retrospective search of the hospital medical record system was conducted to identify all patients who had received tigecycline, eravacycline, or omadacycline. Relevant patient information was collected, and blood samples were obtained from patients who had received eravacycline or omadacycline for more than 72 hours. No intervention or follow-up was performed. The clinical data collected included the following:Demographic data: sex, weight, age, etc.Type of infection and causative strain(s): site of infection, detected strain(s), whether the strain was drug-resistant, and presence of co-infection.Laboratory tests including complete blood count, liver and renal function: red blood cell count, white blood cell count, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), fibrinogen (FIB), fibrin degradation products (FDP), total bilirubin (TBIL), albumin (ALB), serum creatinine (CREA), creatinine clearance (CLcr), C-reactive protein, procalcitonin, etc.Efficacy and safety: whether clinical improvement occurred; discharge, transfer to another hospital, or time of death; and reported possible adverse events.Concomitant medications: other antimicrobial agents or drugs affecting metabolic enzyme function.Eravacycline or omadacycline administration details and blood sampling times: administration times and blood sampling times for eravacycline or omadacycline, as well as the dose administered and dosing interval. |
