RESUMEN
INTRODUCTION: Controlling insulin-treated diabetes is challenging in low-resource settings where only Neutral Protamine Hagedorn (NPH), regular (R) and premixed insulin formulations are available, self-monitoring of blood glucose (SMBG) supplies are scarce and food insecurity is common. We examined the impact of a treatment protocol that includes sliding scale-based 70/30 insulin adjustments in Haiti. METHODS: Thirty young patients aged 11-28 years with diabetes treated with premixed 70/30 insulin twice daily were included in the study. The participants performed one or two daily self-monitoring of blood glucose (SMBG) tests and attended our diabetes clinic monthly. They were randomized to two treatment groups, with one group remaining on the 70/30 insulin formulation (group 70 [G70]) and the other group switching to self-mixed NPH + R (group NR [GNR]). Sliding scales for insulin correction doses and meal insulin doses were designed based on the total daily insulin dose (TDD), carbohydrate ratio and insulin sensitivity factor. SMBG tests and insulin were administered before the morning and evening meals. The frequency of visits to the diabetes clinic was increased to biweekly during a 14-week follow-up. RESULTS: Fifteen patients of each group were included in the analysis. Baseline characteristics, increase in total daily dose and number of missed SMBG tests and skipped meals at 14 weeks did not differ between the two groups. Hemoglobin A1c (HbA1c) decreased from 9.5% (interquartile range [IQR] 8.8, 10.5) (80.3 mmol/mol) to 8.0% (IQR 7.1%, 9.0%) (63.9 mmol/mol) in G70 (p = 0.01), and from 10.6% (IQR 8.1,% 13.1)% (92.4 mmol/mol) to 9.0% (IQR 7.6%, 9.6%) (74.9 mmol/mol) in GNR (p = 0.10), with no significant between-group difference in reductions (p = 0.12). No serious acute complications were reported. Stopping the use of sliding scales and resuming monthly visits increased HbA1c to values not significantly different from baseline in both groups after 15 weeks. CONCLUSION: The use of sliding scales adjusted for missed SMBG tests and skipped meals, and frequent clinic visits that focus on patient self-management education significantly improved glycemic control in the patients with youth-onset diabetes in our study treated with premixed 70/30 human insulin in a low-resource setting.
RESUMEN
Background The objective of this study was to determine the demographic and clinical features of youth supported by member associations of the Federación Mexicana de Diabetes and the Life for a Child Program (LFAC). Methods An analysis of 2017 Annual Clinical Data Sheets of 306 subjects from five Mexican centers was performed. Results Type 1 diabetes (T1D) was diagnosed in 292 subjects; 54.6% were female, with six diagnosed aged <6 months (genetic tests not yet conducted). Type 2 diabetes (T2D) or other types were diagnosed in 11 and three subjects, respectively. T1D diagnosis age ranged 0.0-22.6 years with a peak at 8 years. The mean ± standard deviation (SD) diabetes duration was 5.3 ± 3.5 years (range 0.0-21.0 years), with a mean ± SD subject age at check-up of 13.3 ± 4.3 years. Of the T1D subjects, 1.0%, 6.7%, 13.7% and 78.6% were receiving 1, 2, 3 and ≥4 insulin injections/day with a mean ± SD daily dose of 0.92 ± 0.34 U/kg. The median number of blood glucose tests/week was 40. The mean/median hemoglobin A1c (HbA1c) levels for those with duration ≥6 months were 8.7/8.4% (72/68 mmol/mol) and were higher in adolescents vs. children. Elevated body mass index SD, triglycerides (≥150 mg/dL) and non-high-density lipoprotein (HDL)-cholesterol (≥130 mg/dL) were common: 7.6%, 11.0% and 12.7% (n = 288, 218 and 180, respectively). Serum creatinine levels were normal in all tested subjects (n = 194). Conclusions Youth with diabetes in less-resourced families in Mexico are achieving reasonable glycemia. Most T1D patients use a basal bolus insulin regimen and test blood glucose several times daily. Some subjects have adverse vascular risk factor profiles. Further attention is needed to prevent chronic complications. Monogenic diabetes is very likely in some youth, and genetic testing is indicated.

OBJECTIVES: To determine incidence, mortality, and clinical status of youth with diabetes at the Centro Vivir con Diabetes, Cochabamba, Bolivia, with support from International Diabetes Federation Life for a Child Program. METHODS: Incidence/mortality data analysis of all cases (<25 year (y)) diagnosed January 2005-February 2017 and cross-sectional data (December 2015). RESULTS: Over 12.2 years, 144 cases with type 1 diabetes (T1D) were diagnosed; 43.1% were male. Diagnosis age was 0.3-22.2 y; peak was 11-12 y. 11.1% were <5 y; 29.2%, 5-<10 y; 43.1%, 10-<15 y; 13.2%, 15-<20 y; and 3.5%, 20-<25 y. The youngest is being investigated for monogenic diabetes. Measured incidence in Cercado Province (Cochabamba Department) was 2.2/100,000 children < 15 y/y, with ≈80% ascertainment, giving total incidence of 2.7/100,000 children < 15 y/y. Two had died. Crude mortality rate was 2.3/1000 patient years. Clinical data on 141 cases <35 y: mean/median HbA1c was 8.5/8.2% (69/62 mmol/mol), levels higher in adolescents. Three were on renal replacement therapy; four others had substantial renal impairment. Elevated BMI, triglycerides, and cholesterol were common: 19.1%, 18.3%, and 39.1%, respectively. CONCLUSIONS: Bolivia has low T1D incidence. Reasonable glycemic control is being achieved despite limited resources; however, some have serious complications and adverse cardiovascular risk factor profiles. Further attention is needed for complications.
