-
Nephrotic syndrome Group:
- Age between 18-70 years old
- Diagnosed with nephrotic syndrome: proteinuria≥3.5 g/24h or morning urine protein/creatinine ratio ≥3.0g/g), with serum albumin <30g/L present at the time of enrollment, with or without edema or hyperlipidemia
- Calculated creatinine clearance (CrCl) >50ml/min using the Cockcroft-Gault formula
- Actual body weight >60kg, and body mass index within the range of 18.5-28kg/m2
- Signed informed consent form
-
Healthy volunteer Group:
- Age between 18-70 years old
- Serum albumin ≥40g/L
- Calculated CrCl >50ml/min using the Cockcroft-Gault formula
- Actual body weight >60kg, and body mass index within the range of 18.5-28kg/m2
- Signed informed consent form
-
Serun albumin <30 g/L for other reasons in patients with nephrotic syndrome as judged by the investigator
-
Prolonged PT, INR, APTT at baseline (defined as greater than the upper limit of normal values)
-
Platelet count <100×109/L or ≥300×109/L due to hematological diseases confirmed by laboratory tests
-
History of: gastrointestinal bleeding, intracranial hemorrhage, hemoptysis, or other clinically documented bleeding from internal organs within the last 3 months; surgery (except >3 days after renal biopsy without bleeding complications) or trauma. Bleeding complications after renal biopsy are defined as: ① bleeding (hematuria, perirenal hematoma, or arteriovenous fistula) that occur after renal biopsy requiring transfusion, resulting in altered hemodynamics, or requiring surgery or interventional treatment; ② symptomatic perirenal hematoma; and ③visible hematuria that persist for >3 days postoperatively.
-
A lesion or condition with a significant risk of major bleeding, such as current or recent gastrointestinal ulcer, malignant tumors with a high risk of bleeding, esophageal varices, arteriovenous malformations, vascular aneurysms, or major intravertebral or intracerebral vascular malformations.
-
Serious bleeding disorders as judged by the investigator
-
Systemic lupus erythematosus with or without renal damage
-
Bleeding or thrombophilia disorders as judged by the investigator
-
History of stroke
-
History of congestive heart failure (New York grade II or above) at the time of screening
-
Liver dysfunction (cirrhosis or bilirubin >2×, and serum transaminases >3×, upper limit of normal)
-
Use of (but not limited to) the prescription medications that are inhibitors or inducers of CYP3A4 and/or P-gp within the past 14 days:
-
CYP3A4 inducers (e.g., rifampicin, carbamazepine, phenytoin, etc.) ②CYP3A4 inhibitors (e.g., ketoconazole, ritonavir, clarithromycin, etc.)
- P-gp inducers (e.g., apalutamide, rifampicin, etc.) ④ P-gp inhibitors (e.g., dronedarone, cyclosporine, erythromycin, ketoconazole, quinidine, verapamil, amiodarone, etc.) ⑤Selective serotonin reuptake inhibitors (SSRI) or serotonin-norepinephrine reuptake inhibitors (SNRI)
-
-
Use of antiplatelet and/ or anticoagulant agents within 5 half-lives (at least 7 days): including but not limited to heparin, heparin derivatives, aspirin, clopidogrel, prasugrel, nonsteroidal anti-inflammatory drugs, warfarin, rivaroxaban, dabigatran, apixaban, etc.
-
Pregnant or breastfeeding women or women of childbearing age without contraception
-
Uncontrolled severe hypertension (SBP≥180mmHg, DBP≥110mmHg)
-
Conditions considered unsuitable for inclusion in this study, judged by investigator
-
Patients with hypersensitivity to the active ingredient or other excipients of the Edoxaban and enoxaparin sodium
-
History of immune-mediated heparin-induced thrombocytopenia (HIT) or presence of circulating antibodies within the previous 100 days.
-
Spinal or epidural anesthesia or local anesthesia within 24 hours prior to the administration of enoxaparin sodium and Edoxaban
