在依赖输血的β-thalassemia患者中,高的后负载葡萄糖差距预测了未来的失糖症和糖尿病. 这一发现凸显了除了标准口服葡萄糖耐受性测试 (OGTT) 外,需要进行个性化风险评估.
科学领域:
- 内分泌学 在内分泌学.
- 血液学 血液学 血液学
- 代谢障碍 代谢障碍 代谢障碍
背景情况:
- 输血依赖性β-thalassemia (β-TDT) 患者经常发生异常的葡萄糖平衡.
- 标准口服葡萄糖耐受性测试 (OGTT) 可能无法识别所有患有失糖症高风险的人.
研究的目的:
- 为了评估血葡萄糖 (PG) 在OGTT期间的增量上升差距,作为β-TDT患者患有失糖症和血症相关糖尿病 (Th-RDM) 的早期预测指标.
- 在β-TDT患者中评估PG-gap (2h-PG减去FPG),患者的快餐血葡萄糖 (FPG) 和正常葡萄糖耐受性 (NGT) 是正常的.
主要方法:
- 来自伊朗,意大利和希腊的58名β-TDT患者接受了常规的OGTT.
- 计算了血葡萄糖 (PG) 差距 (2h-PG - FPG),并将患者分为低,中和高负载后差距组.
- 在6-8年的随访数据中,分析了失糖症和Th-RDM的发病率.
主要成果:
- 与高后负载差距组 (P=0.028) 相比,在负载后葡萄糖差距较低和中等的患者中观察到显著较低的失糖症和Th-RDM发病率.
- 在随访期间,高负载后差距组中的三名患者发展了Th-RDM.
- 血清费里丁 (SF) 和年龄在最后一次随访时与2h-PG显著相关 (P=0.0203和P=0.0414,分别).
结论:
- 负载后高血葡萄糖差 (≥30 mg/dL) 表明6-8岁以上β-TDT患者的葡萄糖失调风险增加.
- 这一指标对于对β-TDT患者进行个性化风险评估至关重要,它补充了标准诊断标准.
- 对于β-TDT患者的葡萄糖代谢障碍的早期检测和干预策略至关重要.
