Serum iron status of under-five children with sickle cell anaemia in lagos, Nigeria.

Background. Iron status in patients with sickle cell anaemia is a matter of continuing investigation. Objective. This paper aims to determine the serum iron status of under-five, sickle cell anaemia patients. Methods. The study spanned from December 2009 to February 2010 at the Consultant Outpatient Clinics involving 97 HbSS subjects and 97 age- and sex-matched HbAA controls. Biochemical iron status was assayed in subjects and controls. Results. Age range of the children was seven months to five years, with a mean of 30.6 (±15.97) months. Irrespective of gender, mean serum iron values were higher in HbAA controls than their HbSS counterparts but the observed difference was not significant (P = 0.299 and 0.111, resp.). The mean total iron binding capacity values of males and females were also not significantly different for sickle cell anaemia subjects and controls (P > 0.05). Males and females with HbAA had significantly lower serum ferritin when compared with their HbSS counterparts. Irrespective of gender, mean transferrin saturation was lower in HbSS subjects but the difference was not statistically significant (P > 0.05). Conclusion. Children with sickle cell anaemia have higher serum ferritin than controls, implying relatively higher iron content in the reticuloendothelial cells.
