研究目的: |
主要目的: 1.评价与传统治疗方案相比,联合卡谷氨酸治疗在新生儿有机酸血症所致高氨血症的有效性,以血氨水平降低幅度、速度,临床症状改善情况以及住院时间变化等为主要观察指标,判断其对疾病整体转归的影响; 2.评估卡谷氨酸用于新生儿有机酸血症所致高氨血症治疗的安全性,重点关注药物不良反应的发生率、类型及严重程度。 次要目的:探索卡谷氨酸在不同血氨水平患儿中与肾替代治疗的协同性以及减少肾替代治疗的比例。 |

Objectives of Study: |
Primary Objectives: 1. To evaluate the efficacy of carglumic acid combination therapy versus conventional treatment in neonates with hyperammonemia caused by organic acidemia, using reduction in blood ammonia levels (magnitude and rate), clinical symptom improvement, and changes in hospitalization duration as primary indicators to assess its impact on overall disease outcomes; 2. To assess the safety of carglumic acid in treating hyperammonemia caused by organic acidemia in neonates, focusing on the incidence, types, and severity of adverse drug reactions. Secondary Objective: To explore the synergy between carglumic acid and renal replacement therapy in neonates with varying blood ammonia levels, as well as its potential to reduce the proportion of patients requiring renal replacement therapy. Secondary Objective:To explore the synergistic effects between carglumic acid and renal replacement therapy (RRT) in patients with varying blood ammonia levels, and to investigate its potential to reduce the proportion requiring RRT. |
