摘要BACKGROUND The classification of ketosis-onset diabetes is controversial,and the prevalence and clinical characteristics of diabetic retinopathy(DR)in ketosis-onset diabetes mellitus remain unclear.AIM To compare the prevalence and risk factors of DR among patients with type 1 diabetes mellitus(T1DM),ketosis-onset diabetes,and non-ketotic type 2 diabetes mellitus(T2DM).METHODS This real-world observational study enrolled 1777 patients with newly diagnosed diabetes between January 2003 and December 2012,including 211 with T1DM,673 with ketosis-onset diabetes,and 893 with non-ketotic T2DM.DR was assessed using digital nonmydriatic fundus photography,and its severity was graded based on the ETDRS classification.Clinical characteristics and risk factors of DR were compared across the three groups.RESULTS After controlling for age and sex,DR prevalence was significantly higher in ketosis-onset diabetes(9.5%)than in T1DM(5.7%,P=0.034),but not significantly different from non-ketotic T2DM(12.3%,P=0.105).Risk factors for DR in ketosis-onset diabetes and non-ketotic T2DM included increased estimated glomerular filtration rate(eGFR)and urinary albumin excretion.In contrast,elevated eGFR and 2-hour postprandial C-peptide were independent risk factors for DR in T1DM.The prevalence and risk factors for DR in ketosis-onset diabetes were similar to those in non-ketotic T2DM,but differed from T1DM.CONCLUSION These findings further support classifying ketosis-onset diabetes as a subtype of T2DM rather than idiopathic T1DM.However,the distinctive clinical features of ketosis-onset diabetes should not be ignored.
