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.

Glycosylated haemoglobin is markedly elevated in new and known diabetes patients with hyperglycaemic ketoacidosis
Abstract
Background: Glycosylated haemoglobin (HbA1c) and random blood glucose are markers of chronic and acute hyperglycaemia respectively.
Objective: We compared HbA1c levels in ketoacidosis (DKA) occurring in known and newly diagnosed diabetes.
Methods: Retrospective review of medical records for 83 DKA admissions in 2008 and 2009 with results for HbA1c at presentation
Results: There were 52 and 31 DKA admissions in known and newly diagnosed diabetes patients respectively. Fifty of the 83 DKA admissions were in females. The mean age (per admissions) and HbA1c of all admissions are 43.4 ± 20.3 years (n=83) and 12.7 ± 3.4 % (n=83) respectively. Mean HbA1c in known Type 1, known Type 2 and newly diagnosed diabetes patients were similarly very high: 12.4 ± 3.3 %, 12.5 ± 3.3 %, 13.1 ± 3.7 %; P = 0.6828. The HbA1c levels in newly diagnosed diabetes patients less than 30 years (likely Type 1 diabetes) and ≥ 30 years (likely Type 2 diabetes) were similar. There was a tendency to significantly positive correlation between blood glucose and HbA1c in new diabetes patients.
Conclusions: In our setting, DKA is associated with markedly elevated HbA1c levels in known type 1, known type 2 and new onset diabetes.
Key words: Glycosylated haemoglobin, ketoacidosis, Known and newly diagnosed diabetes
