While African Health Sciences has been freely accessible online there have been questions on whether it is Open Access or not. We wish to clearly state that indeed African Health Sciences is Open Access. There are key issues regarding Open Access needing clarification for avoidance of doubt:
- 1. Henceforth, papers in African Health Sciences will be published under the CC BY (Creative Commons Attribution License) 4.0 International. See details on https://creativecomons.org/)
- 2. The copyright owners or the authors grant the 3rd party (perpetually and in advance) the right to disseminate, reproduce, or use the research papers in part or in full, format/medium as long as:
- No substantive errors are introduced in the process
- Attribution of authorship and correct citation details are given
- The referencing details are not changed.
Should the papers be reproduced in part, this must be clearly stated.
- 3. The papers will be freely and universally accessible online in an easily readable format such as XML in at least one widely recognized open access repository such as PUBMED CENTRAL.

Prevalence of sickle cell trait and its association to renal dysfunction among blood donors at university of medical sciences teaching hospital, Ondo, Nigeria
Abstract
Introduction: Prospective blood donors are routinely screened for blood borne infections but medical illnesses and haemo- globin genotype are overlooked despite a high prevalence of haemoglobin AS among Nigerian donors.
Objective: To determine the prevalence of haemoglobin AS and its association to renal function, if any.
Method: Apparently healthy donors were studied between February and December 2018. Their haemoglobin genotype and, estimated glomerular filtration rates were determined.
Results: There were 96 males (94.1%) and 6 (5.9%) females with mean age of 26.7±4.5 years (range 19-44 years) and mean eGFR of 103.97±19.00ml/min/1.73m2. Eighty one (79.4%) and 21 (20.6%) subjects had haemoglobin AA and AS geno- types respectively. The mean eGFR for subjects with haemoglobin AA and AS were 105.2±18.6ml/min/1.73m2 and 99.9 ± 21.2ml/min/1.73m2 respectively (p value = 0.270). Eighty one (79.4%), 20 (19.6%) and 1 (1.0%) subjects had renal function at >90ml/min/1.73m2, 60-89ml/min/1.73m2 and 30-59ml/min/m2 respectively. There was no significant difference in the mean eGFR between subjects with haemoglobin AA and AS (mean difference 5.3, p = 0.265, 95%CI = -4.07 to 14.60).
Conclusion: The prevalence of sickle cell trait among Nigerian blood donors is high. There is no significant difference in the renal function status of blood donors with SCT and normal haemoglobin genotype.
Keywords: Haemoglobin genotype; sickle cell trait; renal function; blood donor; Nigeria.
