چکیده
BACKGROUND Sickle cell disease is a genetic haemoglobinopathy with consequent haemolysis and anaemia. It is of interest to study its effect on red cell indices beside haemoglobin concentration. OBJECTIVES The objective of the study is to determine the values of red cell indices in preschool-age children with sickle cell anaemia. METHODS we conducted a cross-sectional study including 97 children with sickle cell anaemia aged six months to five years and 97 age-and sex-matched healthy controls with haemoglobin genotype AA (Hb AA). The red cell indices such as packed cell volume, haemoglobin concentration, mean corpuscular volume, red blood cell count, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration were investigated, using an auto analyzer. RESULTS The mean PCV, haemoglobin concentration and red blood cell count were significantly higher in HbAA controls (p = 0.000 in each case). The mean MCV was higher among HbSS subjects but it was only among females and when the result was analyzed irrespective of gender that the difference was statistically significant (p < 0.05). CONCLUSION Children with sickle cell anaemia in steady state have lower values of all red cell parameters and higher values of MCV, compared to haemoglobin phenotype AA controls.

Objective(s) Sickle cell disease is a genetic disorder characterized by chronic haemolytic anaemia. Haemoglobin S containing red blood cells may be susceptible to oxidative stress due to imbalance between production of reactive oxygen species and the countering effect of the various antioxidants present in the body. Materials and Methods We evaluated some antioxidant enzymes which include gl...

Sickle cell disorder is the most important genetic haematological disease that affects the people of black African descent. About 2% of all babies born to Nigerian parents have sickle cell anaemia (1). The distribution of indigenous sickle cell disorder coincides with the distribution of falciparum malaria. Possession of sickle cell trait confers a natural protection against death from malaria ...

Background Sickle cell nephropathy is a major cause of morbidity and mortality in sickle cell anaemia (SCA). Proteinuria contributes to progression of renal damage. Icroalbuminuria is an early feature of SCN and progression to advanced kidney damage is delayed if regression is achieved with angiotensin converting enzyme inhibitors. We aimed to ...

Background: Until now, trimodal distribution of HbS has been seen by six different studies in the world when associated with alpha-thalassemia with confirmation by corresponding alpha-genotyping studies. The RBC indices reduce as alpha-globin genes reduce in sickle cell trait (SCT) patients, which decreases the extent of intra-vascular sickling and thus betters the clinical cou...
