    Item
    An audit of children with Type 1 diabetes mellitus presenting to a tertiary institution in Johannesburg, South Africa
    (2024) Gray, Meghann
    At initial diagnosis, the rate of diabetes ketoacidosis (DKA) varies between countries (15- 67%) and may be associated with a lack of awareness of early signs and symptoms. Objectives: To describe the demographic, anthropometric, clinical and biochemical characteristics of children presenting with Type 1 diabetes mellitus (DM). Methods: A retrospective review of Type 1 DM children's medical records admitted to CHBAH from 01 January 2009 to 31 December 2018 was conducted. This ten-year period was further subdivided into two groups (Group 1: 2009-2013 (n = 75); Group 2: 2014-2018 (n=78)) to assess annual follow-up visit data in Group 1 for five years per patient and to compare data between the Group 1 and 2 time periods. Statistical differences between groups were analyzed by Mann-Whitney U test or Student t-tests, and for between the years of follow-up (Group 1), the paired student t-test was used. Results: The total number of newly diagnosed Type 1 DM children was 153. The median age at presentation was 10.5 years (IQR 7.4-12.3), 56% females and 88% black. The mean WAZ and HAZ were -0.8 (SD ± 1.5) and -0.4 (SD ± 1.6) respectively. Sixty-five percent (n = 100) presented in DKA, 56% of those being severe with a higher prevalence of DKA in group 2 compared to group 1 (72% vs 59%; p=0.08). At presentation, the median HbA1c was 12.5% (IQR 11.1-14.3) and C-peptide was 0.2ug/L (IQR 0.1-0.4) (normal range 1.1-1.4). Anti-GAD antibodies were positive in 82% (n=82/101) of the results available. In Group 1, HbA1c increased at year 3 follow up with advancing pubertal status. Despite changing to more intensive insulin therapy, mean HbA1c remained unchanged over the 5 years of follow-up. Conclusion: The majority of newly diagnosed children presented in severe DKA, similar to Red Cross War Memorial Children's Hospital (2005-2009), with an increasing prevalence over the ten vii years, which could be attributed to the lack of awareness of Type 1 DM in our population. An education campaign is needed to improve community knowledge about diabetes.
