Background and Objectives . There is no data analyzing the outcome of blood transfusions and oral iron therapy in patients with kidneys failure in sub-Saharan Africa. The present study aimed to fill that gap and assess the value of ferritin in the diagnosis of iron overload and deficiency.  Design . From January to February 2012, we prospectively studied 85 hemodialysis patients (78% of males and 22% of females aged 20 to 79 years) attending the Gabonese National Hemodialysis Centre.  Results . Correlation studies showed (a) a strong positive linear relationship between the number of blood transfusions and high serum ferritin in hemodialysis patient (Spearman  r  : 0.74;  P  value: 0.0001); (b) a weak association between the number of blood transfusions and serum iron concentrations (Spearman  r  : 0.32;  P  value: 0.04); (c) a weak association between serum ferritin and serum iron (Spearman  r  : 0.32;  P  value: 0.003). Also, the strength of agreement beyond chance between the levels of ferritin and iron in the serum was poor ( κ  = 0.14). The prevalence of iron overload was 10.6%, whereas the prevalence of iron deficiency was 2.3%, comparing (1) patients with a maximum of one transfusion not on iron therapy; (2) patients with a maximum of one transfusion on iron therapy; (3) polytransfused patients not on iron therapy; and (4) polytransfused patients on oral iron therapy. The “Kruskal-Wallis test” showed that ferritin levels varied significantly between the groups ( P  value: 0.0001).  Conclusion . Serum ferritin is not reliable as a marker of iron overload. For patients undergoing regular transfusion we recommend routine serum ferritin measurement and yearly measurement of LIC.
