【摘要】目的评价低蛋白饮食加α-酮酸(开同)治疗慢性肾功能不全合并继发性甲状旁腺亢进的疗效。方法选择30例慢性肾功能不全合并继发性甲状旁腺亢进患者,肌酐200~700μmol/L,用低蛋白饮食加α-酮酸治疗3个月,每天蛋白质摄入量0.6g/kg,开同4~8片/d,观察生化指标:肌酐、尿素氮、全段甲状旁腺激素、血钙、血磷、碱性磷酸酶、HCO-3等治疗前后的变化。结果治疗第1个月患者的全段甲状旁腺激素、血磷等有所下降,治疗3个月时下降更显著。结论低蛋白饮食加α-酮酸能有效治疗慢性肾功能不全合并继发性甲状旁腺功能亢进。

【Abstract】ObjectiveTo appraise the effect of low protein diet plus α-ketonic acid in the treatment of chronic renal failure complicated with secondary hyperparathyroidism.Methods30 patients with chronic renal failure complicated with secondary hyperparathyroidism,whose creatinine level was about 200~700μmol/L,were treated with low protein diet plus α-ketonic acid for 3 months (protein intake 0.6g per day and ketonsteril 4~8 tablets,qd).Their biochemical indixes:creatinine,urine nitrogen,parathyroid hormone,blood calcium,blood phosphorus,alkaline phosphatase and bicarbonate before and after treatment were observed.ResultsPatients’ parathyroid hormone,blood phosphorus and etc.decreased 1 month later after the treatment,and 3 months later more obviously.ConclusionLow protein diet plus α-ketonic acid treat chronic renal failure complicated with secondary hyperparathyriodism effectively.

继发性甲状旁腺功能亢进(secondary hyperarathyroidism,SHPT)为慢性肾功能衰竭(chronic renal failure,CRF)常见并发症。它不仅可以引起纤维性骨炎、肾性骨营养不良,而且可以累及心血管系统、造血系统、神经系统[1]等,目前临床上治疗SHPT除了补钙和用磷结合剂,没有特别有效的方法。本文通过低蛋白饮食加α-酮酸探讨一条治疗慢性肾功能衰竭继发性甲状旁腺功能亢进的新途径。
