OBJECTIVETo evaluate day-to-day variations of insulin needs in type 2 diabetic patients with end-stage renal disease (ESRD) on maintenance hemodialysis.RESEARCH DESIGN AND METHODSWe developed a 24-h euglycemic clamp in patients who received an average of 2,200 calories in a standardized three-meal and two-snack regimen per day, adjusted to body size and sex. Intravenous insulin was adjusted every 30 min to achieve 5.5 ± 1.1 mmol/l glycemia over 24 h prehemodialysis, during hemodialysis session, and 24 h posthemodialysis in 10 type 2 diabetic patients, aged 55.7 ± 8.7 years with 11.9 ± 4.5 years diabetes duration, undergoing maintenance hemodialysis for 2.3 ± 2.3 years. Insulin requirements were derived from the dose of insulin administered to maintain euglycemia per period of time and day-to-day comparisons performed.RESULTSMean capillary glycemia was 5.5 ± 0.3 mmol/l prehemodialysis and 5.3 ± 0.2 mmol/l posthemodialysis (P = 0.39). Pre- and posthemodialysis areas under the glucose curve were comparable. This was achieved by infusing 23.6 ± 7.7 IU/24 h prehemodialysis vs. 19.9 ± 4.9 IU/24 h posthemodialysis, indicating a 15.3% decrease posthemodialysis (P = 0.09). Basal insulin needs decreased from 0.4 ± 0.1/h prehemodialysis to 0.3 ± 0.1/h posthemodialysis (P = 0.01). Total boluses were decreased by 2.2 ± 3.1 IU (P = 0.15). Changes in blood urea did not correlate with changes in insulin needs (r = 0.1, P = 0.79).CONCLUSIONSThe present study has demonstrated a significant 25% reduction in basal insulin requirements the day after dialysis compared with the day before. No significant change in boluses was observed, and overall the reduction of total insulin requirements was −15% equivalent to −4 IU/day posthemodialysis of marginal statistical significance.

ObjectivesThis study aims to describe the prevalence of glycemic control and related factors in a population of Sub-Saharan African T1D patients. We carried out a cross-sectional study including children and adolescents from seven different centers of the Changing Diabetes in Children (CDiC) program. All children enrolled in the program where recruited after parental consent. Diabetes history, daily practice anthropometrics parameters and HbA1c were assessed for each participant.ResultsWe enrolled 95 children adolescents, aged from 06 to 19 years. The mean HbA1c was 9.2 ± 2.5% and 67.4% of participant had poor glycemic control. There was an association between study level of the patients (p = 0.03), healthy eating habits (p < 0.001), diabetes duration (p < 0.001) and level of glycemic control on univariate analysis. On multivariate analysis, diabetes diagnosed for more than 2 years was associated to a good control compared to those with diagnosis that is more recent. Glycemic control of adolescents with type1 diabetes remain very poor in Cameroon despite the implementation of free diabetes care through the program CDiC.
