Fulminant type 1 diabetes: The clinical and continuous glucose monitoring characteristics in Chinese patients.

Artigo em Inglês | MEDLINE | ID: mdl-31050819
The purpose of the current study was to investigate the clinical characteristics of fulminant type 1 diabetes mellitus (FT1DM) in Chinese patients and to further determine their glycaemic profiles through continuous glucose monitoring (CGM). Thirty subjects who were diagnosed with FT1DM according to the 2012 JDS criteria were enrolled. Clinical characteristics were compared to those reported in Japanese FT1DM. All subjects received retrospective CGM for 3 days after being converted to subcutaneous insulin injection therapy. Chinese FT1DM patients presented with a shorter duration of symptoms (2.84 ± 2.42 days vs 4.4 ± 3.1 days, P < 0.01), worse islet function (fasting C-peptide, 0.09 ± 0.11 ng/mL vs 0.30 ± 0.21 ng/mL; 2-hour C-peptide, 0.13 ± 0.14 ng/mL vs 0.30 ± 0.30 ng/mL, both P < 0.01), lower prevalence of flu-like symptoms (46.7% vs 71.4%, P < 0.05), and a significantly higher GADA positive rate (23.3% vs 5.1%, P < 0.01) when compared with Japanese patients. The CGM results showed that the mean time in range (TIR) of FT1DM patients was 49.8 ± 22.1%, while mean amplitude of glycaemic excursion (MAGE) and standard deviations of sensor glucose (SDSG) were 7.58 ± 3.59 mmol/L and 3.19 ± 1.22 mmol/L, respectively, with nearly 1/3 participants coefficient of variation (CV) > 36% (all are male), suggesting a large glucose fluctuation. The female patients were further divided into pregnancy-related FT1DM (PF) and non-PF (NPF) subgroups (both n = 5), and we found that PF patients had a significantly higher TIR than NPF patients (77.0 ± 16.1% vs 41.0 ± 22.4%, P < 0.05). There were heterogeneities in the clinical characteristics of FT1DM patients, and the CGM results indicated a very low TIR and large glucose fluctuation which needs careful attention.
