We report the case of a 5 month old breast fed infant who presented with a history of vomiting, pallor, and failure to thrive. Investigations showed severe nutritional vitamin B12 deficiency with a megaloblastic pancytopenia. This deficiency was due to low vitamin B12 concentrations in the maternal breast milk, and subsequent investigations showed maternal pernicious anaemia. Treatment of the infant with vitamin B12 resulted in a rapid clinical and haematological improvement. This case represents an unusual presentation of pernicious anaemia.
我们报告了一例5个月大的母乳喂养婴儿的病例,该婴儿有呕吐、面色苍白和发育不良的病史。检查显示严重的营养性维生素B12缺乏伴巨幼细胞性全血细胞减少。这种缺乏是由于母乳中维生素B12浓度低,随后的检查显示母亲患有恶性贫血。用维生素B12治疗该婴儿后,临床和血液学状况迅速改善。该病例代表了恶性贫血的一种不寻常表现。
