Pancytopenia in a patient receiving home intravenous nutrition.

A patient is described who developed pancytopenia several months after home intravenous nutrition (IVN) was started following a major small bowel resection for volvulus. In the post-operative period his weight fell by about 15 kg to 45 kg. Bone marrow aspiration and leucokinetic studies were carried out which suggested that bone marrow failure was the cause of this patient's haematological abnormalities. Five of the 16 patients at St Mark's Hospital who are receiving home IVN were noted to have had transient neutropenia. In 3 of these patients significant weight loss was also noted in the few months preceding the development of neutropenia. It is suggested that there is an association between relative energy malnutrition and the development of the haematological abnormalities that have been observed. In the patient described here these abnormalities were prolonged.
