Background:
Partial remission (PR) is a special stage in type 1 diabetes (T1D). The different patterns of PR frequency, characteristics, and determinants in juvenile and adult patients are unclear, and data on Chinese are lacking.
Methods:
A total of 186 children and 114 adults with T1D who were regularly followed up in a cohort were included for analysis. PR was defined according to C-peptide ≥300 pmol/L or index of insulin dose-adjusted hemoglobin A1c ≤9, as previously recommended. C-peptide and islet autoantibodies were determined with chemiluminescence and radioimmunoassay, respectively.
Results:
The frequency of PR in children was higher than that in adults, with the proportion being 69.9% and 58.8%, respectively (P < .05). For juvenile-onset T1D, the frequency of PR gradually decreased as the onset age decreased, from 87.5% in 13- to 18-year olds to 46.5% in under 6-year olds. Multivariable analyses showed that onset age and male sex were positively related with the frequency of PR in children, while the related factors in adults were initial glycosylated hemoglobin A1c and C-peptide levels. The median PR duration was similar in children (14.8 ± 1.2 months) and adults (16.4 ± 1.9 months). Older onset age was related with a longer PR duration in children, but no such associations were found in adult individuals.
Conclusions:
Children and adults with T1D have different patterns on PR frequency, clinical characteristics, and determinants. For patients during this special phase, the relatively high C-peptide level and to reduce insulin dosage accordingly should be emphasized in clinical practice.
