Riboflavin transporter deficiency (RTD) is a rare genetic disorder that affects riboflavin transport, leading to impaired red blood cell production and resulting in pure red cell aplasia. Recognizing and understanding its clinical manifestations, diagnosis, and management is important.
A 2-year-old patient presented with pure red cell aplasia as the primary symptom of RTD. After confirming the diagnosis, rapid reversal of anemia was achieved after high-dose riboflavin treatment.
RTD often has an insidious onset, and neurological symptoms appear gradually as the disease progresses, making it prone to misdiagnosis. Genetic testing and bone marrow biopsy can confirm the diagnosis.
核黄素转运蛋白缺乏症(RTD)是一种罕见的遗传性疾病,会影响核黄素的转运,导致红细胞生成受损,进而引发纯红细胞再生障碍。认识并了解其临床表现、诊断和治疗方法很重要。
一名2岁患者以纯红细胞再生障碍作为RTD的主要症状就诊。确诊后,大剂量核黄素治疗使贫血迅速得到缓解。
RTD通常起病隐匿,随着病情进展,神经系统症状会逐渐出现,容易误诊。基因检测和骨髓活检可确诊。
