Objectives: The objective of this study was to assess the prevalence of albuminuria in sickle cell disease patients at the Campus University Hospital of Lome. Patients and method: Albuminuria was assessed by the urinary albumin-to-creatinine ratio (UACR) in sickle cell disease individuals who attended the outpatient consultation in their steady state. Results: The prevalence of albuminuria was 21% (14/67). Albuminuria was more frequent (32% vs 13%, p=0,054) and occurred earlier (6 years vs 21 years) among the 28 SS/Sβ0-thalassemia sickle-cell diseases individuals than the 39 SC ones. Albuminuria was associated with high counts of leukocytes (p=0.033) and neutrophils (p=0.008). It was negatively correlated with hemoglobin level (p=0.032) and positively with LDH (p=0.002), SGOT (p=0.002), leukocytes (p=0.003), neutrophils (p< 0.001) and thrombocytes (p=0.010) counts for all sickle cell patients without statistical confirmation for each sickle cell phenotype apart from neutrophils in SS/Sβ0-thalassemia. Defining albuminuria as an UACR greater than 20 mg/g had a specificity of 100% and a sensibility and 90% when the UACR was compared to the 24-hours urines albumin quantification. Conclusion:The assessment of albuminuria should begin at age 5 years in SS/Sβ0-thalassemia sickle-cell anemia patients and from 20 years old in SC patients by the UACR.
