基于 NHANES 数据库中年人群血清同型半胱氨酸水平与肾功能下降的阈值效应分析

Threshold effect of serum homocysteine level on kidney function decline among middle-aged adults in America based on NHANES database

:1061-1068
 
       目的   血清同型半胱氨酸(Hcy)水平与慢性肾脏病(CKD)的进展相关,但中年人群的非线性关联研究较少,本研究旨在寻找慢性肾脏病危险因素。方法   本研究基于NHANES 1996—2006年数据,纳入5 361例45~65岁参与者,以估算肾小球滤过率(eGFR)<60 mL/(min·1.73 m2 )和尿白蛋白/肌酐比值(uACR)≥30 mg/g评估肾功能下降。结果   通过逻辑回归及平滑曲线拟合分析发现,Hcy每升高1 µmol/L,eGFR降低的风险增加8%(OR=1.08,95%CI1.06~1.10),uACR升高的风险增加2%(OR=1.02,95%CI:1.00~1.04)。非线性分析显示,Hcy对eGFR的阈值效应拐点为13.4 µmol/L(拐点左侧OR=1.59,95%CI:1.49~1.70;右侧无显著关联)。亚组分析表明,性别、高血压、糖尿病等协变量无交互作用,然而,在敏感性分析中,糖尿病患者中Hcy与eGFR降低的关联更强(交互P=0.015 8)。结论   本研究提示,控制Hcy水平或可延缓美国中年人群(尤其是糖尿病患者)的肾功能衰退。
        Objective   Elevated serum homocysteine(Hcy)levels are linked to chronic kidney disease(CKD)progression,yet the nonlinear relationship in middle-aged populations remains underexplored.Methods  This  study analyzed data from 5 361 participants aged 45–65 years in the NHANES 1996–2006 cohort.Renal dysfunction was defined as an estimated glomerular filtration rate(eGFR)<60 mL/min/1.73 m2  and urinary albumin-to-creatinine ratio(uACR)≥30 mg/g.Results  Logistic regression and smoothed curve fitting revealed that each 1 µmol/L increase in Hcy elevated the risk of reduced eGFR by 8%(OR=1.08,95% CI:1.06–1.10)and uACR by 2%(OR=1.02,95% CI:1.00–1.04).A nonlinear threshold effect was identified at 13.4 µmol/L,with a stronger association below this threshold(OR=1.59,95% CI:1.49–1.70)and no significant effect above it.Subgroup analyses showed no interactions with gender or hypertension,but a stronger Hcy-eGFR association was observed in diabetics(interaction P=0.0158).Conclusions  These findings suggest that controlling Hcy levels may mitigate renal decline,particularly in diabetic populations,warranting further causal investigations.

        目的   分析达格列净联合沙库巴曲缬沙坦治疗射血分数降低的心力衰竭(HFrEF)效果。方法  连续抽取2021年1月—2023年6月在广州市第一人民医院心内科住院的射血分数降低的心力衰竭(HFrEF)患者203例,随访至少6个月,按照接受的治疗进行分组。对照组予常规治疗和沙库巴曲缬沙坦治疗;观察组予常规治疗、沙库巴曲缬沙坦和达格列净治疗;对比两组疗效,观察指标包括住院时间,入院及出院后6个月的心功能状态(NYHA纽约心脏病协会心功能分级)、心脏超声指标左室射血分数(LVEF)、左室舒张末内径(LVEDD)、左室收缩末内径(LVSDD)、血液指标-端脑钠肽前体(NT-proBNP N)、糖化血红蛋白(HBA1c)、血肌酐(Cr)、6个月时的再住院率及全因死亡率。结果   观察组心脏监护病房(CCU)停留时间(2.54±1.26)d,短于对照组的(3.73±1.21)d;观察组6个月时观察组心功能NYHA改善≥2级比例为95.05%高于对照组的86.27%,差异有统计学意义(P<0.05);观察组6个月时的LVEDD、LVESD水平分别为(48.22±7.35)(34.61±4.32)mm,低于对照组的(51.47±8.02)(43.07±5.33)mm,LVEF为(51.49±5.40)%,高于对照组的(46.18±4.21)%,差异有统计学意义(P<0.05);6个月时观察组的NT-proBNP为(415.58±31.57)pg/mL,低于对照组的(520.23±385.56)pg/mL,差异有统计学意义(P<0.05);两组的住院时间、血清肌酐(Cr)、HBA1c、6个月时的再住院率、全因病死率对比,差异不显著(P>0.05)。观察组HBA1c值为(6.04±0.66)mmol/L,高于对照组的(5.20±0.56)mmol/L(P<0.05)。结论  HFrEF患者采取达格列净+沙库巴曲缬沙坦治疗,可通过协同作用,缩短CCU停留时间,改善患者6个月时的心功能状态,降低NT-proBNP值,减少心脏扩大趋势,提高LVEF水平。

       Objective  To analyze the efficacy of  dapagliflozin combined with  sacubitril/valsartan in the treatment of heart failure with reduced ejection fraction(HFrEF).Methods  A total of 203 patients with HFrEF who were hospitalized in the cardiology department of the hospital between January 2021 and June 2023 were enrolled and followed up for at least six months.Patients were divided into groups based on their treatment regimens:the control group received conventional treatment plus sacubitril/valsartan,while the observation group received conventional treatment plus sacubitril/valsartan and dapagliflozin.The two groups were compared for clinical outcomes,including length of hospital stay,cardiac function(NYHA classification)at admission and six months after discharge,echocardiographic indicators(LVEF,LVEDD,LVESD),blood indicators(NT-proBNP,HbA1c,creatinine),six-month rehospitalization rate,and all-cause mortality.Results  The observation group had a shorter CCU stay(2.54±1.26 days)compared to the control group(3.73±1.21 days).At sixth month,the proportion of patients in the observation group with an NYHA improvement ≥2 grades(95.05%)was significantly higher than that in the control group(86.27%)P<0.05).The observation group demonstrated lower LVEDD(48.22±7.35 mm)and LVESD(34.61±4.32 mm)levels and higher LVEF(51.49±5.40%)compared to the control group(LVEDD:[51.47±8.02] mm,LVESD:[43.07±5.33]mm,LVEF:[46.18±4.21]%)(P<0.05).NT-proBNP levels in the observation group([415.58±31.57] pg/mL)were significantly lower than those in the control group([520.23±385.56] pg/ml)(P<0.05).There were no significant differences between the two groups in length of total hospital stay,serum creatinine,HbA1c,six-month rehospitalization rate,or all-cause mortality(P>0.05).However,HbA1c levels in the observation group([6.04±0.66] mmol/L)were higher than those in the control group([5.20±0.56] mmol/L)(P<0.05).Conclusions  The combination of dapagliflozin and sacubitril/valsartan in the treatment of HFrEF patients can exert a synergistic effect,shorten CCU stay,improve cardiac function at sixth month,reduce NT-proBNP levels,mitigate cardiac dilation,and increase LVEF.
