title: Sickle cell disease in North London.
abstract: We have examined our experience of sickle cell disease in the London Borough of Haringey over the past 20 years. There are currently (1986) 145 patients on the Haringey Sickle Cell Register and when comparison is made with other centres, admission for painful crises in Hb SS disease is more frequent than in Jamaica, but the acute chest syndrome appears to be less common in the United Kingdom than in Jamaica. Splenomegaly is less frequent in Hb SC patients in this country and there is also a lower incidence of leg ulceration in both Hb SS and Hb SC disease in the United Kingdom than in Jamaica. The incidence of alloimmunization among transfused sickle cell disease individuals in Haringey is 21%, the most frequently encountered antibodies being anti-E and anti-Kell. All pregnant patients with sickle cell disease were managed with regular blood transfusion throughout pregnancy starting at 12 weeks of gestation. There were no fetal or maternal mortalities, although three babies born were 'small for dates' despite uneventful antenatal courses and adequate Hb A levels being achieved in the mother. Examination of the effect of seasonal variation on the incidence of hospital admissions for painful crises reveals no significant clustering of cases in a particular month or season of the year.
