ABSTRACT
OBJECTIVE: To report the evolution of metabolic control and to assess the clinical and metabolic factors associated with the presence of microvascular complications in patients with type 1 diabetes mellitus (T1DM). MATERIAL AND METHODS: This was a retrospective, observational study analysing clinical, laboratory, and therapeutic data from a registry of patients with T1DM created in 2010. RESULTS: Data recorded from 586 patients (males: 50.2%; mean age: 36.1±13.5 years; T1DM duration: 18.0±12.1 years) followed for a mean of 6.0±3.1 years were assessed, and 8133 HbA1c levels (13.2±7.6 measurements/patient) were analysed, with a mean evolutionary HbA1c of 7.9%±1.2%. The mean annual HbA1c level gradually improved from 8.6%±1.6% in 2010 to 7.5%±1.4% in 2019, with 34.3% and 69.0% of patients having HbA1c levels ≤7% and ≤8% respectively. Patients with T1DM duration of <10 years and ≥20 years, non-smokers, CSII users, and those using the insulin/carbohydrate ratio had better current and evolutionary HbA1c levels. The presence of microvascular complications was independently associated with T1DM lasting ≥20 years, the presence of HBP, and evolutionary HbA1c≥7.0%. CONCLUSION: A progressive but still inadequate improvement in metabolic control over 10 years was seen in patients with T1DM. Poor metabolic control (mean HbA1c over 10 years ≥7%) was independently associated with the presence of microvascular complications.
