[Abstract] Objective To investigate clinical improving effects of α-keto acids on patients with chronic hepatitis B complicated with chronic kidney disease for nutritional status and renal function. Methods 80 patients with chronic hepatitis B complicated with chronic kidney disease were chosen and randomly divided into both groups including control group (40 patients) with low-protein diet and treatment group (40 patients) with compound α-keto acid on the basis of control group; And the clinical curative effect, the levels of severe malnutrition rate (SAG-C), plasma albumin (Alb), high density lipoprotein (HDL), low density lipoprotein (LDL), three triacylglycerol(TG), total cholesterol (TC), 24 h proteinuria, glomerular filtration rate (eGFR) and C reactive protein(CRP) of both groups were compared. Results The clinical efficacy of treatment group was significantly better than that of control group, there was significant difference(P<0.05). The levels of nutritional status indexes of treatment groups after treatment was significantly better than that of control group, there was significant difference(P<0.05). The levels of 24 h proteinuria of treatment groups after treatment was significantly lower than that of control group and before treatment, there was significant difference(P<0.05); And there was no significant difference in level of eGFR between two groups before and after treatment(P>0.05). The levels of CRP of treatment groups after treatment was significantly lower than that of control group and before treatment, there was significant difference (P<0.05). Conclusion The α-keto acids on patients with chronic hepatitis B complicated with chronic kidney disease can efficiently improve nutritional status and protect renal function.

乙型肝炎病毒兼并缓慢肾脏病多见于中青年男性,惯例医治选用饮食低蛋白质摄入计划,有用减轻剩余肾脏担负。但现在研讨显现单纯蛋白质摄入操控疗法效果欠安,无法有用缓解病况开展[1,2]。本次研讨选取乙型肝炎兼并缓慢肾脏病患者80例,别离给予单纯低蛋白饮食和在此基础上加用复方α-酮酸医治,比较两组患者临床效果、医治前后SAG-C率、Alb、HDL、LDL、TG、TC、24 h尿蛋白量、eGFR及CRP等目标水平,评论复方α-酮酸改进乙型肝炎兼并缓慢肾脏病患者养分状况及肾脏功用的临床效果。

1 材料与办法

1.1 临床材料

选取我院肾内科2010年5月~2012年12月收治的乙型肝炎兼并缓慢肾脏病患者80例,选用随机数字表法分为对照组(40例)和医治组(40例)。对照组患者中男28例,女12例,年纪35~62岁,均匀(43.80±6.41)岁;医治组患者中男30例,女10例,年纪36~61岁,均匀(43.87±6.43)岁。两组患者的一般材料比较差异无统计学含义(P>0.05)。

1.1.1 归入规范 ①契合缓慢肾脏病(CKD)Ⅰ-Ⅱ期确诊规范[3];②契合缓慢乙型肝炎确诊规范[3];③未到达缓慢乙型肝炎抗病毒药物医治规范;④签署知情同意书,自愿参加研讨。

1.2 医治办法

对照组患者选用低蛋白饮食医治,每天蛋白质摄入量=24 h尿蛋白量+蛋白质(0.7~0.8)g/kg;医治组患者则在此基础上加用复方α-酮酸(北京费森尤斯卡比医药有限公司,批号81GK307,0.63 g×100片/盒)0.3 g/(kg·d)医治。医治进程中确保每天膳食优质蛋白份额超越70%,总热量摄入坚持125~150 kJ。两组患者医治时刻均为16周。

3 评论

缓慢乙型肝炎兼并缓慢肾脏病患者长时刻处于微炎症状况,机体蛋白质-能量代谢反常,一起因蛋白质于肝脏部位代偿性组成,又可诱发脂质代谢紊乱[7,8],终究构成恶性循环,严峻养分不良发作危险极高。低蛋白饮食疗法有助于改进肾脏功用高滤过状况和蛋白质代谢,在拮抗部分氧化应激反响的一起,调理生长因子、部分激素水平[9,10]。而复方α- 酮酸首要组成成分为α-酮酸和必需氨基酸;其间α-酮酸参加人体氨基酸特别是必需氨基酸组成进程,有助于减轻膳食体外弥补必需氨基酸代谢后废物对剩余肾脏安排功用损害[11]。复方α-酮酸有助于下降缓慢肾脏病患者尿蛋白量,坚持正常肾脏功用效果亦被证明,详细机制如下:①辅佐蛋白质摄入操控计划可进步蛋白质适应性组成水平,安稳机体蛋白质平衡;②其间含有支链氨基酸成分不会诱发肾脏血流量及滤过率改动;③加强支链氨基酸功用在肾小管部位再吸收能力[12-14]。

本次研讨成果中,医治组患者临床效果和医治后24 h尿蛋白量均明显优于对照组,阐明复方α-酮酸辅佐医治乙型肝炎兼并缓慢肾脏病患者在操控尿蛋白、维护肾脏功用方面具有优势,其对肾脏纤维化因子表达高效抑制效果是或许的医治机制之一[15],但因两组均选用低蛋白饮食,下降饮食蛋白量也可有用减轻肾脏担负,下降蛋白尿量[16],详细机制还需进一步评论。而医治组患者医治后养分状况目标明显优于对照组、医治前,差异有统计学含义(P<0.05),提示复方α-酮酸联合低蛋白饮食有助于坚持乙型肝炎兼并缓慢肾脏病患者杰出的养分状况,但因随访时刻较短,远期效果及安全性仍有待进一步承认;一起复方α-酮酸关于氧化应激反响具有清晰抑制效果,可明显下降患者炎症反响水平,而炎症反响水平反常升高可促进患者养分不良状况的发作开展亦被证明[17,18]。本次研讨发现,医治组患者医治后CRP水平明显低于对照组、医治前,差异有统计学含义(P<0.05),与以上定论相一致。

综上所述,复方α-酮酸改进乙型肝炎兼并缓慢肾脏病患者养分状况及肾脏功用效果切当,具有临床使用价值。但因研讨样本量少、单一中心及随访时刻短等约束,所得定论还需更大规划临床随机对照双盲实验确证。
