Title: Prevalence of elevated liver enzymes in adults with type 1 diabetes: A multicentre analysis of the German/Austrian DPV database.
Abstract: AIMS: To assess the prevalence of elevated liver enzymes in adults with type 1 diabetes mellitus (T1DM) in routine clinical care and the association with cardiovascular risk profile in the Diabetes-Prospective-Documentation (DPV) network in Germany and Austria. SUBJECTS AND METHODS: This cross sectional observational study from the DPV registry includes data from 45&#8201;519 adults with T1DM at 478 centres up to September 2016. Liver enzyme measurements were available in 9226 (29%) patients at 270 centres and were analysed for increased alanine aminotransferase (ALT; men >50&#8201;U/L, women >35U/L) and/or aspartate aminotransferase (AST; men >50&#8201;U/L, women >35U/L) and/or gamma-glutamyltransferase (GGT; men >60U/L, women >40&#8201;U/L). A subgroup analysis in patients for whom 2 or more ALT measurements were available (n&#8201;=&#8201;2335, 25%) and whose ALT was increased at least twice (men >30&#8201;U/L, women >19U/L) was performed. Associations with glycaemic control, cardiovascular risk factors and late complications were investigated with multiple regression analyses. RESULTS: Twenty percent (19.8%, n&#8201;=&#8201;1824) had increased liver enzyme(s) on one or more occasions. Increased liver enzymes were associated with worse glycaemic control and higher BMI (both P&#8201;<&#8201;.0001), dyslipidemia (OR, 1.75; 95% CI, 1.54-2.0), hypertension (OR, 1.48; 95% CI: 1.31-1.68), myocardial infarction (OR, 1.49; 95% CI, 1.17-1.91) and end stage renal disease (OR, 1.59; 95% CI, 1.17-2.17). ALT was increased twice in 29% and was associated with worse glycaemic control (P&#8201;<&#8201;.0001), higher BMI (P&#8201;<&#8201;.0001), hypertension (OR, 1.58; 95% CI, 1.26-1.97) and dyslipidemia (OR, 1.89; 95% CI, 1.51-2.37). CONCLUSIONS: In this clinical audit in adults with T1DM, elevated liver enzymes on routine assessment were associated with a less favourable cardiovascular risk profile and with poorer glycaemic control.
