Serum Antioxidant Vitamins Levels in Children with Sickle Cell Anaemia in Sokoto, North Western Nigeria

Abstract


Sickle cell anaemia is associated with elevated oxidative stress via increase generation of reactive oxygen species (ROS), and decline in antioxidant defences. Increased oxidative stress is thought to play a role in the development of sickle cell anaemic complications. In the current study, vitamins A, C, and E levels were estimated in 35 sickle cell anaemics attending the Paediatric medical clinic of the Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria and the results compared with those of apparently healthy non-sickle cell anaemic volunteers of comparable age and social status. Serum levels of vitamin A, C, and E were 31.06 ± 2.97 μg/dl, 0.27 ± 0.05 mg/dl, 0.20 ± 0.01 mg/dl and 69.51 ± 4.54 μg/dl, 0.77 ± 0.10 mg/dl and 0.49 ± 0.02 mg/dl in sickle cell anaemics and non- sickle cell anaemic subjects respectively. There was significantly (P<0.05) decreased levels of antioxidant vitamins in sickle cell anaemic subjects. Age and gender did not have significant (P>0.05) difference. The results suggest that sickle cell anaemics in the study area have low serum levels of antioxidant vitamins, an indication that the sickle cell anaemics are predisposed to increased oxidative onslaught.

Keywords: Sickle cell anaemia, serum vitamins A, C, and E.
