Abstract
We studied the prevalence of hypophosphataemia (<0.80 mmol/1) in seventeen patients who had undergone bone marrow transplantation (BMT). Thirteen (77%) of the seventeen patients had hypophosphataemia at some stage during the conditioning phase or after their BMT. Seven (41%) of the seventeen patients had hypophosphataemia in the peri-BMT period that is during the conditioning phase or within one week thereafter. Two of the patients showed severe hypophosphataemia (<0.30 mmol/1). We suggest that plasma phosphate should be monitored in patients with a bone marrow transplant.
