ABSTRACT
Sickle cell disease patients who acquire iron deficiency may experience a degree of amelioration from painful crises in terms of frequency, severity, and duration. This observation prompted us to identify the potential utility of iron load reduction in the management of this disease. Thirteen sickle cell patients not ameliorated by conventional treatment entered a weekly venesection protocol. Hematological values and painful crises of all degrees of severity were recorded and compared to those of the last 12 months before venesection for each case separately ("historical controls"). A decrease was noted in the frequency and intensity of several types of painful crises. Reduction of iron load by venesection seems to be a simple, safe, side-effect-free, and efficient way of preventing and ameliorating to a large extent painful crises in sickle cell disease. The biological effects of venesection on other parameters of sickle cell disease remain to be determined.
