Minimal change nephropathy

Minimal change disease occurs at all ages, but accounts for nephrotic syndrome (PCR >300 mg/mmol, hypoalbuminaemia [< 30 g/L], oedema and fluid retention) in most children and about one- quarter of adults. It is caused by reversible dysfunction of podocytes. It typically remits with high- dose glucocorticoid therapy (1 mg/kg prednisolone for 6 weeks). Some patients who respond incompletely or relapse frequently need maintenance glucocorticoids, cytotoxic therapy or other agents. Minimal change disease does not progress to CKD but can present with problems related to nephrotic syndrome and complications of treatment.

微小病变性肾小球病

微小病变性疾病可发生任何年龄段，但大多数儿童和大约四分之一的成年患者会进展为肾病综合征［PCR ＞ 300 mg/mmol， 低蛋白血症（＜ 30 g/L），水肿和液体潴留］。微小病变性肾小球病是由足细胞可逆性功能障碍引起的。通常大剂量糖皮质激素治疗（1 mg/kg 泼尼松龙治疗 6 周）可使其缓解。一些反应不完全或频繁复发的患者需要维持糖皮质激素、细胞毒性药物或其他药物治疗。微小病变性肾小球病不会进展为慢性肾病，但会出现与肾病综合征和治疗并发症相关的问题。
