The most common complication of chronic lymphocytic leukaemia (CLL) is
infection, which occurs mainly in advanced stages of disease or in th
ose patients with hypogammaglobulinaemia. Intravenous immune globulin
(IVIG) has been shown to be a useful prophylactic therapy against infe
ctions in such patients. A randomized, double-blind study on 36 patien
ts receiving either 500mg/kg or 250mg/kg IVIG every 4 weeks was undert
aken to determine the dose regimen required. There was no significant
difference in the two treatment groups and we found that CLL patients
were equally protected with low-dose IVIG.
