Typical rickets were observed in a 13 year old Turkish girl and in a 14 year old Moroccan girl. Hypocalcaemia was present in one case. Symptoms have easily regressed with vitamin D2. Seric 25 OH D3 was very low; seric 1-25 OH D3 was normal before treatment and increased very much with vitamin D. In the second case vitamin D deficiency was familial. Study of 15 immigrant children living in or near Saint-Etienne has shown low seric concentrations of 25 OH D3 in 9 (8 undetectable).
在一名13岁的土耳其女孩和一名14岁的摩洛哥女孩身上观察到典型的佝偻病。其中一例存在低钙血症。症状通过维生素D2治疗后很容易消退。血清25-羟维生素D3非常低；治疗前血清1,25-二羟维生素D3正常，补充维生素D后大幅升高。在第二例中，维生素D缺乏是家族性的。对居住在圣艾蒂安或其附近的15名移民儿童的研究显示，9名儿童（8名检测不到）的血清25-羟维生素D3浓度较低。
