  • 文章类型: Journal Article
    达格列净(DPG)是一种钠-葡萄糖协同转运蛋白2(SGLT2)抑制剂,已被认为在糖尿病中具有抗炎特性。这项研究的目的是评估DPG给药在预防脂多糖(LPS)诱导的女性生殖系统损伤中的作用。将32只雌性Wistar白化病大鼠随机分为4组:对照组,LPS组,LPS+DPG组和DPG组。在实验阶段结束时,子房,收集输卵管和子宫组织进行组织病理学检查,免疫组织化学,遗传和生化分析。结果表明,LPS引起的组织病理学改变以明显的充血为特征,轻度至中度出血,女性生殖道水肿和中性粒细胞浸润以及变性和坏死变化。此外,它降低了总抗氧化剂状态(TAS),总氧化状态(TOS)和氧化应激指数(OSI)水平增加。LPS还增加了卵巢中Cas-3、G-CSF和IL-1β的表达,输卵管和子宫免疫组化。而Claudin-1表达降低,NLRP3和AQP4基因表达由于LPS而增加。然而,DPG治疗阻止了所有这些变化。这项研究的结果表明,DPG可用于预防女性生殖系统中LPS诱导的病变。
    Dapagliflozin (DPG) is a sodium-glucose cotransporter-2 (SGLT2) inhibitor that has been suggested to possess anti-inflammatory properties in diabetes. The aim of this study is to evaluate the role of DPG administration in preventing lipopolysaccharide (LPS)-induced damage in the female genital system. Thirty-two female Wistar Albino rats were randomly allocated into four groups: control group, LPS group, LPS + DPG group and DPG group. At the end of the experimental phase, ovary, fallopian tube and uterus tissues were collected for histopathological, immunohistochemical, genetic and biochemical analyses. The findings showed that LPS caused histopathological changes characterized by marked hyperaemia, mild to moderate haemorrhage, oedema and neutrophil leucocyte infiltrations and degenerative and necrotic changes in the female genital tract. In addition, it decreased total antioxidant status (TAS), increased total oxidant status (TOS) and oxidative stress index (OSI) levels. LPS also increased the expressions of Cas-3, G-CSF and IL-1β in the ovary, fallopian tubes and uterus immunohistochemically. While Claudin-1 expression decreased, NLRP3 and AQP4 gene expressions increased due to LPS. However, DPG treatment prevented all these changes. The results of this study indicate that, DPG can be used to prevent LPS-induced lesions in the female reproductive system.

    这项荟萃分析调查了达格列净作为2型糖尿病(T2DM)和慢性肾脏病(CKD)2-5期患者辅助治疗的疗效。对选定的随机对照试验数据库进行了系统搜索,这些数据库报告了估计的肾小球滤过率(eGFR)和尿白蛋白-肌酐比(UACR)相对于基线的平均变化。在1682项确定的研究中,包括13,057名患者的9项试验。5项研究的汇总估计表明达格列净不影响eGFR;然而,在两项研究中,与安慰剂相比,它显着降低了慢性eGFR下降(平均差异[MD]±2.74;95%置信区间[CI]:1.55,3.92;P<0.00001)。此外,4项研究的汇总估计显示达格列净显著降低UACR(MD-23.99%;95%CI:-34.82--13.15;P<0.0001;I2=0%).因此,长期使用达格列净可显著减轻T2DM和CKD患者的eGFR下降并减少白蛋白尿.
    This meta-analysis investigated efficacy of dapagliflozin as adjunctive therapy for patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD) stages 2-5. A systematic search was conducted of selected databases for randomised controlled trials that reported the mean change in estimated glomerular filtration rate (eGFR) and urine albumin-creatinine ratio (UACR) from baseline. Out of 1,682 identified studies, 9 trials comprising 13,057 patients were included. A pooled estimate of 5 studies indicated that dapagliflozin did not affect eGFR; however, in 2 studies, it significantly reduced chronic eGFR decline compared to placebo (mean difference [MD] ± 2.74; 95% confidence interval [CI]: 1.55, 3.92; P <0.00001). Additionally, a pooled estimate of 4 studies showed that dapagliflozin significantly reduced UACR (MD -23.99%; 95% CI: -34.82--13.15; P <0.0001; I2 = 0%). Therefore, long-term use of dapagliflozin significantly attenuates eGFR decline and reduces albuminuria in patients with T2DM and CKD.

    目的:评价达格列净与安慰剂的疗效和安全性,以治疗未达到适当血糖控制的2型糖尿病患者。
    方法:在这个多中心中,随机化,双盲,安慰剂对照3期试验,糖化血红蛋白(HbA1c)水平≥7.0%(≥53mmol/mol)和≤10.5%(≤91mmol/mol)的患者接受稳定剂量二甲双胍(≥1000mg)和伊沃格列汀(5mg)至少8周的随机分组,接受达格列净10mg或安慰剂,每日1次,共24周.参与者继续使用二甲双胍和依格列汀治疗。主要终点是治疗24周后HbA1c水平从基线水平的变化。
    结果:总计,198例患者被随机分组,195例患者被纳入疗效分析(达格列净:96例,安慰剂:99例).在第24周,达格列净显著降低了HbA1c水平。治疗24周后,HbA1c水平相对于基线变化的最小二乘平均差为-0.70%(-7.7mmol/mol)(p<0.0001)。达格列净组中达到HbA1c<7.0%(≥53mmol/mol)的参与者比例高于安慰剂组。与安慰剂相比,达格列净显著降低空腹血糖,平均每日葡萄糖,餐后2小时血浆葡萄糖,空腹胰岛素,尿酸和γ-谷氨酰转移酶水平,胰岛素抵抗指数的稳态模型评估,体重,肝脂肪变性指数,和蛋白尿。达格列净治疗24周后,脂联素水平明显高于基线水平。两组的不良事件发生率相似。
    结论:达格列净联合二甲双胍可改善血糖控制,目标患者耐受性良好。
    OBJECTIVE: To evaluate the efficacy and safety of dapagliflozin versus placebo as an add-on in patients with type 2 diabetes who did not achieve adequate glycaemic control with evogliptin and metformin combination.
    METHODS: In this multicentre, randomized, double-blind, placebo-controlled Phase 3 trial, patients with glycated haemoglobin (HbA1c) levels ≥7.0% (≥53 mmol/mol) and ≤10.5% (≤91 mmol/mol) who had received stable-dose metformin (≥1000 mg) and evogliptin (5 mg) for at least 8 weeks were randomized to receive dapagliflozin 10 mg or placebo once daily for 24 weeks. Participants continued treatment with metformin and evogliptin. The primary endpoint was change in HbA1c level after 24 weeks of treatment from baseline level.
    RESULTS: In total, 198 patients were randomized, and 195 patients were included in the efficacy analyses (dapagliflozin: 96, placebo: 99). At Week 24, dapagliflozin significantly reduced HbA1c levels. The least squares mean difference in HbA1c level change from baseline after 24 weeks of treatment was -0.70% (-7.7 mmol/mol) (p < 0.0001). The proportion of participants achieving HbA1c <7.0% (≥53 mmol/mol) was higher in the dapagliflozin group than in the placebo group. Compared to placebo, dapagliflozin significantly reduced fasting plasma glucose, mean daily glucose, 2-h postprandial plasma glucose, fasting insulin, uric acid and gamma-glutamyl transferase levels, homeostatic model assessment for insulin resistance index, body weight, hepatic steatosis index, and albuminuria. Adiponectin level significantly increased from baseline level after 24 weeks of dapagliflozin treatment. Adverse event rates were similar in the two groups.
    CONCLUSIONS: Dapagliflozin add-on to evogliptin plus metformin improved glycaemic control and was well tolerated by the target patients.

    本系统综述探讨达格列净对2型糖尿病患者心力衰竭(HF)和急性心肌梗死(MI)的影响。通过分析最近的研究,包括随机对照试验(RCT)和回顾性分析,这篇综述提供了这种钠-葡萄糖协同转运蛋白2(SGLT2)抑制剂对心血管作用的见解.研究结果一致证明了达格列净在减少HF相关住院和改善已确诊HF患者预后方面的益处。这些积极影响似乎超出了血糖控制范围,提出了多种作用机制。达格列净对急性心肌梗死结局的影响尚不清楚,研究结果参差不齐。重要的是,dapagliflozin在改善患者生活质量方面显示出希望,并且通常具有良好的耐受性。该综述表明,达格列净可能在控制糖尿病患者的心血管风险方面发挥重要作用。特别是那些有HF或有HF风险的人。虽然证据令人鼓舞,审查还强调了需要进一步调查的领域。这些包括确定最有可能从达格列净中受益的患者亚组,阐明其心脏保护作用的确切机制,并进行长期结果研究。
    This systematic review explores the impact of dapagliflozin on heart failure (HF) and acute myocardial infarction (MI) in patients with type 2 diabetes mellitus. By analyzing recent studies, including both randomized controlled trials (RCTs) and retrospective analyses, this review provides insights into the cardiovascular effects of this sodium-glucose cotransporter 2 (SGLT2) inhibitor. The findings consistently demonstrate the benefits of dapagliflozin in reducing HF-related hospitalizations and improving outcomes for patients with established HF. These positive effects appear to extend beyond glycemic control, suggesting multiple mechanisms of action. The impact of dapagliflozin on acute MI outcomes is less clear, with mixed results across studies. Importantly, dapagliflozin shows promise in improving the quality of life of patients and is generally well-tolerated. The review suggests that dapagliflozin may play a significant role in managing cardiovascular risk in diabetic patients, particularly those with or at risk of HF. While the evidence is encouraging, the review also highlights areas requiring further investigation. These include determining the patient subgroups most likely to benefit from dapagliflozin, elucidating the precise mechanisms underlying its cardioprotective effects, and carrying out long-term outcome studies.

    钠-葡萄糖协同转运蛋白-2(SGLT2)抑制剂由于其心血管益处而广泛用于治疗心力衰竭。与达格列净相关的药物不良反应包括糖尿病酮症酸中毒,真菌感染,血糖浓度升高。然而,异常子宫出血不是达格列净的已知副作用。我们报告了一名75岁的中国女性,患有扩张型心肌病和慢性心力衰竭,在服用达格列净时经历了异常子宫出血。值得注意的是,停止dapagliflozin给药导致子宫出血消失。这些发现表明达格列净具有其他潜在机制,但是这些机制需要进一步调查。此外,当开dapagliflozin处方时,医护人员应该对子宫出血的发生保持警惕.
    Sodium-glucose cotransporter-2 (SGLT2) inhibitors are extensively used in the management of heart failure because of their cardiovascular benefits. Adverse drug reactions associated with dapagliflozin include diabetic ketoacidosis, fungal infections, and increased blood glucose concentrations. However, abnormal uterine bleeding is not a known side effect of dapagliflozin. We report a 75-year-old Chinese woman with dilated cardiomyopathy and chronic heart failure who experienced abnormal uterine bleeding while taking dapagliflozin. Notably, cessation of dapagliflozin administration resulted in the disappearance of uterine bleeding. These findings suggest that dapagliflozin possesses additional potential mechanisms, but these mechanisms require further investigation. Furthermore, healthcare professionals should remain vigilant regarding the occurrence of uterine bleeding when prescribing dapagliflozin.

    目的:我们评估了药代动力学,安全,在健康的西方和韩国参与者中,达格列净/西格列汀固定剂量组合(FDC)与单组分(IC)片剂的耐受性。这些抗高血糖药物的组合提供了有效的血糖控制,FDC的使用通常被证明可以改善2型糖尿病(T2DM)患者的用药依从性.
    方法:两个随机,开放标签,两期,两种治疗,单剂量,单中心,纳入了对健康禁食的德国参与者(年龄18~55岁;西方研究)和韩国参与者(年龄19~55岁;韩国研究)进行的交叉生物等效性研究.在两项研究中,药代动力学参数(最大[峰值]血浆浓度[Cmax],从零到最后一个可量化浓度[AUClast]的血浆浓度-时间曲线下面积,和从零到无穷大的血浆浓度-时间曲线下面积[AUCinf])用于评估10mg达格列净/100mg西格列汀FDC(治疗A)与其IC(治疗B)在禁食条件下的生物等效性。在整个研究中评估安全性和耐受性。
    结果:46名健康参与者(男性,60.9%;平均年龄,39.5岁;平均体重指数[BMI],23.9kg/m2)在西方研究中随机分组,和51名健康参与者(男性,100.0%;平均年龄,24.6年;平均BMI,23.9kg/m2)在韩国研究中随机分配。在两项研究中,参与者以1:1随机分为治疗序列AB和治疗序列BA.在西方和韩国研究中,达格列净/西格列汀FDC与IC片剂生物等效,因为达格列净和西格列汀的药代动力学参数的几何最小二乘平均值的FDC与IC比值的90%置信区间均在0.8000~1.2500生物等效性标准界限内.观察到的药代动力学参数差异,比如Cmax,AUClast,AUCinf,西方和韩国的研究没有临床意义.达格列净/西格列汀FDC及其IC耐受性良好,在任何研究人群中均未报告严重不良事件。
    结论:10mg达格列净/100mg西格列汀FDC和IC制剂在禁食的西方和韩国健康参与者中具有生物等效性,没有发现新的安全问题,因此,为目前接受单独药物作为治疗方案一部分的患者提供了一种有用的替代方案。
    背景:西方研究(clinicaltrials.gov:NCT05266404)和韩国研究(clinicaltrials.gov:NCT05453786)。
    OBJECTIVE: We evaluated the pharmacokinetics, safety, and tolerability of a fixed-dose combination (FDC) of dapagliflozin/sitagliptin versus individual component (IC) tablets in healthy Western and Korean participants. The combination of these antihyperglycemic drugs provides efficient glucose control, and the use of FDC has generally been shown to improve medication adherence in individuals with type 2 diabetes mellitus (T2DM).
    METHODS: Two randomized, open-label, two-period, two-treatment, single-dose, single-center, crossover bioequivalence studies conducted on healthy fasted German participants (aged 18-55 years; Western study) and South Korean participants (aged 19-55 years; Korean study) were included. In both studies, pharmacokinetic parameters (maximum [peak] plasma concentration [Cmax], area under the plasma concentration-time curve from zero to the last quantifiable concentration [AUClast], and area under the plasma concentration-time curve from zero to infinity [AUCinf]) were used to assess the bioequivalence of 10 mg dapagliflozin/100 mg sitagliptin FDC (Treatment A) with their ICs (Treatment B) under fasted conditions. Safety and tolerability were assessed throughout the study.
    RESULTS: Forty-six healthy participants (male, 60.9%; mean age, 39.5 years; mean body mass index [BMI], 23.9 kg/m2) were randomized in the Western study, and 51 healthy participants (male, 100.0%; mean age, 24.6 years; mean BMI, 23.9 kg/m2) were randomized in the Korean study. In both studies, the participants were randomized 1:1 into treatment sequence AB and treatment sequence BA. Dapagliflozin/sitagliptin FDC was bioequivalent to IC tablets in both Western and Korean studies, as the 90% confidence interval of the FDC to IC ratios of the geometric least-squares means of the pharmacokinetic parameters for both dapagliflozin and sitagliptin was within the 0.8000-1.2500 bioequivalence criterion limit. The observed differences in pharmacokinetic parameters, such as Cmax, AUClast, and AUCinf, between the Western and Korean studies were not clinically meaningful. Dapagliflozin/sitagliptin FDC and their ICs were well tolerated, with no serious adverse events reported in any of the study populations.
    CONCLUSIONS: The 10 mg dapagliflozin/100 mg sitagliptin FDC and IC formulations were bioequivalent in fasted healthy Western and Korean participants, with no new safety concerns identified, thus offering a useful alternative for patients currently receiving individual medications as part of their treatment regimen.
    BACKGROUND: Western study (clinicaltrials.gov: NCT05266404) and Korean study (clinicaltrials.gov: NCT05453786).

    钠-葡萄糖协同转运蛋白-2抑制剂(SGLT-2i)最近被认为与急性胰腺炎(AP)有关,但临床特征尚不清楚。本研究探讨SGLT-2i和AP的临床特点,为AP的预防和治疗提供参考。
    病例报告,案例系列,SGLT2i诱导的AP的临床研究是通过从数据库中检索中文和英文数据收集的,直到2023年12月31日。
    包括21名患者,年龄中位数为50.5岁(范围为26,73)。SGLT-2i主要受累于依帕列净(13例,61.9%),canagliflozin(4例,19%)和达格列净(4例,19%)。从初始给药到AP发作的中位时间为21天(范围1,120)。腹痛(21例,100%)是最常见的主诉症状。脂肪酶中值为388U/L(范围36,10000),淀粉酶中值为535U/L(范围26,3765)。21例患者在停药并接受保守治疗后完全康复。
    SGLT-2i与AP关联。鉴于SGLT-2i的处方不断上升,在排除其他病因后,医师应将这些药物视为胰腺炎的潜在病因.
    UNASSIGNED: Sodium-glucose cotransporter-2 inhibitors (SGLT-2i) have recently been linked to be associated with acute pancreatitis (AP), but the clinical characteristics are unclear. This study investigated the clinical characteristics of SGLT-2i and AP and provided reference for the prevention and treatment of AP.
    UNASSIGNED: Case reports, case series, and clinical studies of SGLT2i induced AP were collected by retrieving Chinese and English data from the database until 31 December 2023.
    UNASSIGNED: Twenty-one patients were included, with a median age of 50.5 years (range 26,73). SGLT-2i were mainly involved in empagliflozin (13 cases, 61.9%), canagliflozin (4 cases, 19%) and dapagliflozin (4 cases, 19%). The median time from initial administration to the onset of AP was 21 days (range 1, 120). Abdominal pain (21 cases, 100%) was the most commonly complained symptom. The median lipase value was 388 U/L (range 36, 10000), and the median amylase value was 535 U/L (range 26, 3765). Twenty-one patients recovered completely after stopping the drug and receiving conservative treatment.
    UNASSIGNED: SGLT-2i are associated with AP. Given the rising prescription of SGLT-2i, physicians should consider these agents as a potential cause of pancreatitis after excluding other etiologies.

    高尿酸性肾病(HN)是一种以尿酸(UA)代谢功能障碍为特征的全球性代谢紊乱,导致高尿酸血症(HUA)和肾小管间质纤维化(TIF)。钠依赖性葡萄糖转运蛋白2抑制剂,dapagliflozin,已显示出降低慢性肾脏病(CKD)患者血清UA水平的潜力,尽管其对HN的保护作用仍不确定。这项研究调查了功能性,病态,和HN通过组织学的分子变化,生物化学,以及对患者的转录组学分析,HN小鼠,和UA刺激的HK-2细胞。研究结果表明UA诱导的肾小管功能障碍和纤维化激活,达格列净可显着缓解。转录组分析确定雌激素相关受体α(ERRα),HN中下调的转录因子。ERRα敲入小鼠和ERRα过表达的HK-2细胞表现出UA抗性,而ERRα抑制会加剧UA效应。达格列净靶向ERRα,激活ERRα-有机阴离子转运蛋白1(OAT1)轴以增强UA排泄并减少TIF。此外,达格列净改善非HNCKD模型中的肾纤维化,强调ERRα-OAT1轴在HN和CKD中的治疗意义。
    Hyperuricemic nephropathy (HN) is a global metabolic disorder characterized by uric acid (UA) metabolism dysfunction, resulting in hyperuricemia (HUA) and tubulointerstitial fibrosis (TIF). Sodium-dependent glucose transporter 2 inhibitor, dapagliflozin, has shown potential in reducing serum UA levels in patients with chronic kidney disease (CKD), though its protective effects against HN remain uncertain. This study investigates the functional, pathological, and molecular changes in HN through histological, biochemical, and transcriptomic analyses in patients, HN mice, and UA-stimulated HK-2 cells. Findings indicate UA-induced tubular dysfunction and fibrotic activation, which dapagliflozin significantly mitigates. Transcriptomic analysis identifies estrogen-related receptor α (ERRα), a downregulated transcription factor in HN. ERRα knockin mice and ERRα-overexpressed HK-2 cells demonstrate UA resistance, while ERRα inhibition exacerbates UA effects. Dapagliflozin targets ERRα, activating the ERRα-organic anion transporter 1 (OAT1) axis to enhance UA excretion and reduce TIF. Furthermore, dapagliflozin ameliorates renal fibrosis in non-HN CKD models, underscoring the therapeutic significance of the ERRα-OAT1 axis in HN and CKD.

    我们比较了非2型糖尿病患者在开始服用达格列净治疗慢性肾病(CKD)后的尿白蛋白-肌酐比值(UACR)水平的肾脏和心肾保护作用。
    OPTIMISE-CKD是一项观察性研究,描述达格列净治疗CKD。无2型糖尿病的CKD成年患者被纳入主要分析。基线UACR分为正常/轻度升高(0-29mg/g),低(30-200毫克/克)和高(>200毫克/克)。结果是估计的肾小球滤过率(eGFR)轨迹/斜率,心肾并发症和全因死亡率。
    总共,1480例患者的UACR低(n=796)和高(n=684)。两组在基线时相似,75岁和74岁,42%和39%是女性,分别。达格列净开始服用后,观察到3毫升/分钟/1.73平方米的急性eGFR下降,其次是两组的发展。低UACR患者的eGFR斜率[95%置信区间(CI)]为每年0.79mL/min/1.73m2(-0.59,2.56),与高UACR患者相似[每年0.40mL/min/1.73m2(-0.46,1.38)]。心肾并发症和全因死亡率的风险相似,调整后的风险比为0.89(95%CI0.66,1.19)和1.10(95%CI0.63,1.92),分别。在UACR正常/轻度升高的患者中发现了类似的结果。
    达帕格列净在无2型糖尿病的CKD患者中表现出相似的肾脏保护作用,不同UACR水平的心肾和全因死亡风险。这表明在临床试验中发现的达格列净的疗效扩展到现实世界的CKD患者,不管蛋白尿水平。
    UNASSIGNED: We compared kidney and cardiorenal protection in patients without type 2 diabetes across urine albumin-creatinine ratio (UACR) levels after initiation on dapagliflozin for the treatment of chronic kidney disease (CKD).
    UNASSIGNED: OPTIMISE-CKD is an observational study describing dapagliflozin treatment for CKD. Adult patients with CKD without type 2 diabetes were included in the primary analysis. Baseline UACR was grouped as normal/mildly elevated (0-29 mg/g), low (30-200 mg/g) and high (>200 mg/g). Outcomes were estimated glomerular filtration rate (eGFR) trajectories/slopes, cardiorenal complications and all-cause mortality.
    UNASSIGNED: In total, 1480 patients had low (n = 796) and high (n = 684) UACR. The two groups were similar at baseline, aged 75 and 74 years, and 42% and 39% female, respectively. After dapagliflozin initiation, an acute eGFR dip of 3 mL/min/1.73 m2 was observed, followed by a flat development in both groups. The eGFR slope [95% confidence interval (CI)] for patients with low UACR was 0.79 mL/min/1.73 m2 per year (-0.59, 2.56), and similar to patients with high UACR [0.40 mL/min/1.73 m2 per year (-0.46, 1.38)]. Risks of cardiorenal complications and all-cause mortality were similar, with adjusted hazard ratios of 0.89 (95% CI 0.66, 1.19) and 1.10 (95% CI 0.63, 1.92), respectively. Analogous results were found in those with normal/mildly elevated UACR.
    UNASSIGNED: Dapagliflozin in patients without type 2 diabetes for the treatment of CKD demonstrated similar kidney protection, cardiorenal and all-cause mortality risk across UACR levels. This suggests that the efficacy of dapagliflozin found in clinical trials expands to real-world patients with CKD, regardless of albuminuria levels.

    慢性肾脏疾病(CKD)是糖尿病的并发症,会影响循环药物浓度和体内药物的消除。多种药物可以用于治疗糖尿病和合并症,CKD使药物治疗选择和给药方案复杂化。使用模型表征肾脏药物清除率的变化需要收集昂贵且耗时的大型临床数据集。我们提出了一种灵活的方法,使用描述性统计和次要数据以及机械模型和PK第一原理,将受损的肾脏清除率纳入药代动力学(PK)模型。根据肾功能损害的程度,为各种药物清除机制生成概率密度函数,并用于估计从肾小球滤过开始的二甲双胍(MET)和达格列净(DAPA)的总清除率。将这些估计与MET和DAPA的PK模型整合以进行模拟。MET肾脏清除率与估计的肾小球滤过率(eGFR)和估计的净肾小管转运率的降低成比例地降低。DAPA总清除率随肾脏损害变化不大,并与报告的非肾脏清除率成比例降低。与eGFR相比,净肾小管转运率为阴性,部分原因是肾清除率低。估计的清除率值和趋势与文献中的MET和DAPAPK特征一致。基于降低的清除率水平的剂量调整,对于MET和DAPA估计相应地更低的剂量,同时维持期望的剂量暴露。使用描述性统计和次要数据以及机制模型和PK第一原理来估计药物清除率改善了糖尿病中CKD的建模,并可以指导治疗选择。
    Chronic kidney disease (CKD) is a complication of diabetes that affects circulating drug concentrations and elimination of drugs from the body. Multiple drugs may be prescribed for treatment of diabetes and co-morbidities, and CKD complicates the pharmacotherapy selection and dosing regimen. Characterizing variations in renal drug clearance using models requires large clinical datasets that are costly and time-consuming to collect. We propose a flexible approach to incorporate impaired renal clearance in pharmacokinetic (PK) models using descriptive statistics and secondary data with mechanistic models and PK first principles. Probability density functions were generated for various drug clearance mechanisms based on the degree of renal impairment and used to estimate the total clearance starting from glomerular filtration for metformin (MET) and dapagliflozin (DAPA). These estimates were integrated with PK models of MET and DAPA for simulations. MET renal clearance decreased proportionally with a reduction in estimated glomerular filtration rate (eGFR) and estimated net tubular transport rates. DAPA total clearance varied little with renal impairment and decreased proportionally to reported non-renal clearance rates. Net tubular transport rates were negative to partially account for low renal clearance compared with eGFR. The estimated clearance values and trends were consistent with MET and DAPA PK characteristics in the literature. Dose adjustment based on reduced clearance levels estimated correspondingly lower doses for MET and DAPA while maintaining desired dose exposure. Estimation of drug clearance rates using descriptive statistics and secondary data with mechanistic models and PK first principles improves modeling of CKD in diabetes and can guide treatment selection.
