Abstract:

Background

Chronic kidney disease (CKD) is a worldwide public health problem, stage 4 CKD is a critical stage during the course of CKD, marking the significant decline of kidney function and the obvious appearance of symptoms. Although fermented cordyceps sinensis powder has been used in the treatment of chronic kidney disease for a long time, its prognostic effect on CKD, especially the curative effect of stage 4 CKD, lacks evidence-based medical evidence.

Objective

To explore the long-term prognosis of stage 4 CKD patients treated with fermented cordyceps sinensis powder and the potential related factors affecting the prognosis.

Methods

A total of 631 patients diagnosed with stage 4 CKD in the nephrology Department of Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from 2013 to 2022 were collected. Based on standardized integrated Chinese and Western medicine treatment, patients were divided into cordyceps treatment group (339 cases) and integrated Chinese and Western medicine treatment group (252 cases) according to whether fermented cordyceps sinensis powder was used. Data such as patients' basic information, whether they were accompanied by diabetes, the occurrence and time of endpoint events, the time of diagnosis of stage 4 CKD, and relevant laboratory indicators at diagnosis were collected. After eliminating baseline differences between groups with propensity score matching, COX regression analysis was conducted to analyze potential prognostic factors. Survival curve was drawn by Kaplan-Meier method, and the difference of survival between groups was compared by Log-rank test.

Results

A total of 378 patients were included after matching at a ratio of 1:1. Multivariate Cox proportional hazard regression analysis showed that the using of fermented cordyceps sinensis powder (HR=0.79, 95%CI=0.64-0.98, P=0.030), the increased level of estimated glomerular filtration (HR=0.97, 95%CI=0.94-1.00, P=0.025) and serum albumin (HR=0.97, 95%CI=0.96-0.99, P=0.002) prolonged the survival time of stage 4 CKD patients; male (HR=1.37, 95%CI=1.09-1.71, P=0.006), the increased level of brain natriuretic peptide (HR=1.00, 95%CI=1.00-1.00, P=0.003), blood phosphorus (HR=2.44, 95%CI=1.63-3.67, P<0.001) and 24 h urinary protein (HR=1.00, 95%CI=1.00-1.00, P<0.001) shortened the survival time of patients with stage 4 CKD. The results of survival curve analysis showed that cumulative survival rate of cordyceps treatment group was higher than that of integrated Chinese and Western medicine treatment group (HR=0.70, 95%CI=0.57-0.86, P<0.001). The cumulative survival rate in the low protein level subgroup was higher in the cordyceps treatment patients than in the integrated Chinese and western medicine treatment patients (HR=0.67, 95%CI=0.52-0.85, P<0.001). In the high urinary protein level subgroup, there was no significant difference in cumulative survival between the two treatment groups (P=0.518) .

Conclusion

Long-term use of fermented cordyceps sinensis powder can prolong the progression of renal function in patients with stage 4 CKD, and can play a better clinical effect under the premise of active control of urinary protein. Relatively low levels of brain natriuretic peptide and serum phosphorus, and relatively high levels of serum albumin are also potential factors for good prognosis in patients with stage 4 CKD.

摘要:

背景

慢性肾脏病(CKD)是世界性公共卫生问题,CKD 4期是CKD病程中一个关键的阶段,标志着肾功能的显著下降和症状的明显出现。发酵虫草菌粉虽然长期应用于CKD的治疗之中,但其对CKD的预后影响尤其是CKD 4期的疗效缺乏循证医学证据。

目的

探索发酵虫草菌粉治疗CKD 4期患者的长期预后情况及影响预后的潜在相关因素。

方法

选取2013—2022年于上海中医药大学附属龙华医院肾病科住院诊断为CKD 4期的患者631例为研究对象。在中西医结合治疗的基础上,根据是否使用发酵虫草菌粉分为虫草治疗组(339例)和中西医结合治疗组(252例)。收集患者基本信息、是否伴随糖尿病、发生终点事件情况及进入终点事件时间、确诊CKD 4期时间及确诊时相关实验室指标等资料。采用倾向性得分匹配消除组间基线差异后,通过Cox比例风险回归分析影响CKD 4期患者预后的潜在相关因素;采用Kaplan-Meier法绘制CKD 4期患者预后的生存曲线,采用Log-rank检验比较组间生存情况差异。

结果

按1∶1比例匹配后最终共纳入378例患者。多因素Cox比例风险回归分析结果显示,使用发酵虫草菌粉(HR=0.79,95%CI=0.64~0.98,P=0.030),估算肾小球滤过滤(HR=0.97,95%CI=0.94~1.00,P=0.025)、血清白蛋白(HR=0.97,95%CI=0.96~0.99,P=0.002)水平升高可延长CKD 4期患者的生存时间;男性(HR=1.37,95%CI=1.09~1.71,P=0.006)、脑利钠肽(HR=1.00,95%CI=1.00~1.00,P=0.003)、血磷(HR=2.44,95%CI=1.63~3.67,P<0.001)和24 h尿蛋白(HR=1.00,95%CI=1.00~1.00,P<0.001)水平升高可缩短CKD 4期患者的生存时间。生存曲线分析结果显示,虫草治疗组累积生存率高于中西医结合治疗组(HR=0.70,95%CI=0.57~0.86,P<0.001);低尿蛋白水平亚组中,虫草治疗患者累积生存率高于中西医结合治疗患者(HR=0.67,95%CI=0.52~0.85,P=0.001);高尿蛋白水平亚组中,两治疗组累积生存率比较,差异无统计学意义(P=0.518)。

结论

长期使用发酵虫草菌粉能够延缓CKD 4期患者肾功能进展,在积极控制尿蛋白的前提下可发挥更好的临床疗效。较低水平的脑利钠肽和血磷、较高水平的血清白蛋白也是CKD 4期患者良好预后的潜在因素。
