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.

Renal insufficiency in Ghanaian HIV infected patients: need for dose adjustment
Abstract
Background: Antiretrovirals (ARVs) could lead to clinically significant nephrotoxicity and as such will require dose adjustments in the presence of renal insufficiency.
Objective: To explore renal function estimating equations as alternatives for glomerular filtration rate (GFR) measurement in a stable cohort of HIV-infected patients.
Method: In estimating renal insufficiency in Ghanaian HIV-infected patients, GFR for 276 HAART-naïve patients and 166 patients on HAART was estimated with the Cockcroft-Gault, 4v-MDRD and CKD-EPI estimating equations.
Results: Females outnumbered males by 3 to 1 in the HAART-naïve group and 4 to 1 in subjects on HAART. The prevalence of renal insufficiency calculated with the Cockcroft-Gault, 4v-MDRD and CKD-EPI equations was 8.7%, 9.1% and 8.7% in HAART-naïve patients; 14.5%, 12.6% and 12.6% in patients on HAART; 7.7%, 11.5% and 11.5% in HAARTnaïve males; 10.8%, 8.1% and 8.1% in males on HAART; 9.1%, 8.0% and 7.5% in HAART-naïve females and 15.5%, 14.0% and 14.0% in females on HAART. The CKD-EPI equation yielded lower bias when compared to the Cockcroft-Gault and 4v-MDRD equations.
Conclusion: Renal insufficiency is not uncommon among HIV infected Ghanaian patients. A significant proportion (10 to 11%) will require ARV dose adjustment at the time of initiating therapy or sometime during on-going therapy.
