    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 presentationResults: 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 diabete

    Objectives. To describe the frequencies, presenting characteristics (demographic, clinical and biochemical) and outcomes (duration of admission and mortality rates) for various types of hyperglycaemic crisis. Methods. Retrospective review of medical records of patients with hyperglycaemic crisis admitted to Nelson Mandela Academic Hospital, Mthatha, E Cape, from 1 January 2008 to 31 December 2009. Outcome measures were duration of admission and mortality. Results. Data were available for 269 admissions (response rate 81.0%), 169 females and 100 males. Admissions for hyperglycaemia (HG, N=119), and non-hyperosmolar diabetic ketoacidosis (NHDKA, N=97) were more frequent than those for hyperosmolar hyperglycaemic state (HHS, N=29) and hyperosmolar diabetic ketoacidosis (HDKA, N=24). Duration of admission was similar in all groups. Mortality was high in all groups, but was higher in patients with HDKA (37.5%, risk ratio (RR) 3.88, 95% confidence interval (CI) 1.41 - 10.67, p=0.009), HHS (31.0%, RR 2.91, 95% CI 1.09 - 7.75, p=0.033) and HG (19.5%, RR 1.56, 95% CI 0.75 - 3.21, p=0.236) than in those with NHDKA (13.4%). HDKA (62.5%) was associated with new-onset diabetes more often than NHDKA (27.8%), HHS (44.8%) or HG (17.6%) (

    Preconception care of women with diabetes: a review of current guideline recommendations

    <p>Abstract</p> <p>Background</p> <p>The prevalence of type 2 diabetes mellitus (T2DM) continues to rise worldwide. More women from developing countries who are in the reproductive age group have diabetes resulting in more pregnancies complicated by T2DM, and placing both mother and foetus at higher risk. Management of these risks is best achieved through comprehensive preconception care and glycaemic control, both prior to, and during pregnancy. The aim of this review was to compare the quality and content of current guidelines concerned with the preconception care of women with diabetes and to develop a summary of recommendations to assist in the management of diabetic women contemplating pregnancy.</p> <p>Methods</p> <p>Relevant clinical guidelines were identified through a search of several databases (MEDLINE, SCOPUS and The Cochrane Library) and relevant websites. Five guidelines were identified. Each guideline was assessed for quality using the AGREE instrument. Guideline recommendations were extracted, compared and contrasted.</p> <p>Results</p> <p>All guidelines were assessed as being of high quality and strongly recommended for use in practice. All were consistent in counselling about the risk of congenital malformation related to uncontrolled blood sugar preconceptionally, ensuring adequate contraception until glycaemic control is achieved, use of HBA1C to monitor metabolic control, when to commence insulin and switching from ACE inhibitors to other antihypertensives. Major differences were in the targets recommended for optimal metabolic control and opinion regarding the usage of metformin as an adjunct or alternative treatment before or during pregnancy.</p> <p>Conclusions</p> <p>International guidelines for the care of women with diabetes who are contemplating pregnancy are consistent in their recommendations; however some are more comprehensive than others. Having established current standards for the preconception care of diabetic women, there is now a need to focus on guideline implementation through an examination of the barriers and enablers to successful implementation, and the applicability of the recommendations in the local setting.</p
