Abstract

Aims To determine whether the frequency and severity of diabetic ketoacidosis and the clinical characteristics of children at diagnosis of Type 1 diabetes mellitus have changed over the past decades among patients under surveillance of a tertiary paediatric centre. Methods In three time-periods, 75 (1986-1987), 86 (1996-1997) and 245 (2006-2007) patients at mean age 10.1± 4.7years (0.6-20.0) were diagnosed with new-onset Type 1 diabetes. Data on clinical characteristics and laboratory evaluation at diagnosis retrieved from the patients' files Comparative analysis was performed between the three time periods. Results The frequency of diabetic ketoacidosis at diagnosis was 40% in 1986-1987, 41.8% in 1996-1997 and 29.4% in 2006-2007; the last rate was significantly lower (P=0.04). No significant differences in the proportions of patients with severe or moderate diabetic ketoacidosis were found over time. Mean weight standard deviation score significantly increased from -0.72±1.8 in 1986-1987 to -0.27±1.2 in 2006-2007 (P<0.05), while percentage weight loss (~6.5%) before diagnosis remained unchanged. In 2006-2007 a higher proportion of children had glucose testing at the community clinic before diagnosis, than in the earlier years (73.1 vs. 59.6%, P=0.003). Conclusions The overall frequency of diabetic ketoacidosis in children with newly diagnosed Type 1 diabetes has decreased in the past decade, although the degree of metabolic decompensation has remained unchanged.
