摘  要:目的探讨α-酮酸联合低蛋白饮食治疗慢性乙型肝炎(乙肝)并发慢性肾脏病(CKD)的疗效和安全性。方法采用前瞻性随机对照试验。17例慢性乙肝并发CKD患者按数字随机法分为两组:对照组:蛋白质0.6-0.8g·kg^-1·d^-1+24h尿蛋白量;治疗组:复合α-酮酸制剂(开同,北京费森尤斯卡比公司)0.1g·kg^-1·d^-1+蛋白质0.6-0.8g·kg^-1·d^-1+24h尿蛋白量。饮食中优质蛋白比例超过2/3,热量为125.52-146.44kJ·kg^-1·d^-1。随访3个月,观察比较两组的疗效和安全性。结果随访期内,两组患者的组间及组内Scr、肾小球滤过率差异无统计学意义。在随访开始后的第1个月,治疗组患者的尿微量白蛋白开始持续下降[基线值(2855.43±248.03)mg/L,第1个月(2157.14±218.15)mg/L,第2个月(1681.57±146.18)mg/L,第3个月(924.29±83.33)mg/L,P〈0.05];第3个月时,两组患者的尿微量白蛋白水平差异有统计学意义;治疗组24h尿蛋白总量也显著降低[基线值(4.52±1.74)g,第1个月(3.19±1.52)g,第2个月(2.19±1.10)g,第3个月(1.64±0.77)g,P〈0.05],与对照组差异有统计学意义。从第1个月开始,治疗组和对照组的血钙水平差异有统计学意义,但治疗组各随访点的血钙没有持续上升,各时间点间差异无统计学意义。第3个月时,治疗组组内及两组间的血浆白蛋白水平差异都有统计学意义。随访期间,安全性指标均在正常范围内。结论α-酮酸制剂联合低蛋白饮食能有效地改善慢性乙肝并发CKD患者的血白蛋白水平,降低患者尿蛋白量。随访期间未见不良反应。Objective To evaluate the efficacy and safety of short-term restriction of dietary protein intake (DPI) supplemented with α-keto acids on chronic hepatitis B patients comphcated with chronic kidney diseases (CKD). Methods A prospective randomized controlled trial was carried out. Seventeen chronic hepatitis B patients with CKD were randomized to either low DPI with α-keto acid-supplemented (sLP) or low DPI (LP) group for 3 months. Low-protein diet (LPD) was individualized with total energy intake 125.52-146.44 kJ·kg^-1 ·d^-1, and protein intake of 0.6-0.8 g·kg^-1·d^-1. α-keto acid was supplied in a dosage of 0.1 g·kg^-1·d^-1. Nutritional indexes were recorded and other clinical indexes were measured to evaluate the efficacy and safetyrespectively. Results The urine protein excretion level and microalbuminuria were significantly decreased at the end of the observation period in the sLP group compared to the basal value and the LP group [24 h urine protein:baseline (4.52±1.74) g, the 1st month (3.19±1.52) g, the 2nd month (2.19±1.1) g,the 3rd month (1.64±0.77) g, P〈0.05; microalbuminyria: baseline (2855.43± 248.03) mg/L,the 1st month (2157.14±218.15) mg/L, the 2nd month (1681.57±146.18) mg/L,the 3rd month (924.29±83.33) mg/L, P〈0.05]. No significant difference was found in Scr and eGFR. Nutritional indexes (SGA, serume albumin) were significantly higher at the end of 3 months in the sLP group (P〈0.05). No obvious side-effect occurred. Conclusions Short-term restriction of DPI is safe, and when combined with α-keto acids, can increase serum protein and decrease urine protein excretion in chronic hepatitis B patients complicated with CKD without significant sideeffect.
