Two unusual cases of kwashiorkor: can protein deficiency explain the mystery?

Two children with unusual features of kwashiorkor are reported. One, an exclusively breastfed 7-month-old girl, had been admitted earlier, treated for pneumonia and discharged 3 weeks before she presented with kwashiorkor. The other was an identical twin who was admitted for kwashiorkor and gastro-enteritis. The twin sister was underweight but relatively well. Both children died. Potent aflatoxins were detected in the organs of these children on post-mortem examination. The occurrence of kwashiorkor in a fully breastfed infant and in an identical twin does not accord with the extant belief that the aetiology of kwashiorkor is wholly nutritional, but suggests a disease probably of multifactorial origin.
