    Abstract: Physical inactivity promotes insulin resistance and increases the risk of diabetes and cardiovascular disease. Clustering based on simple clinical measures has been introduced for identifying diabetes subgroups with different risk of complications. However, little is known about physical fitness and cardiovascular risk factors in these clusters. We hypothesized that the insulin resistant diabetes (SIRD) cluster would associate with lower physical fitness and increased cardiovascular risk factors. Cycling spiroerogometry, physical activity questionnaire (Baecke index) and cardiovascular risk scores (Framingham Risk Scores (FRS) and triglycerides to high-density lipoproteins (TG:HDL) ratio) were analyzed in 746 participants with newly diagnosed diabetes of the German Diabetes Study (GDS). SIRD showed lower VO2max compared to the severe autoimmune diabetes (SAID), moderate age-related (MARD) and moderate obesity-related (MOD) clusters (all p & lt;0.01) but was not different to the severe insulin deficient (SIDD) cluster (p= 0.87). Further, Baecke index was lower in SIRD [7.3 (6.8-8.4)] than SAID [8.5 (7.6-9.5)] and MARD [8.4 (7.3-9.4)] and SIRD had the highest TG:HDL ratio compared to all other groups (p & lt;0.05) after adjustments for age, sex and BMI. This was underlined by a strong association between estimates of insulin resistance (HOMA-IR) and TG:HDL ratio (r= 0.59 p= & lt;.0001) across all groups. Finally, SIRD showed higher FRS [33.1 (25.3-54.9)%] compared to MOD [16.2 (7.4-24.4)%] , SAID [3.9 (1.6-9.4)%] and SIDD [12.4 (4.7-34.9)%] . In conclusion, SIRD and MARD showed lowest physical fitness and SIRD was least physically active and has the highest risk scores for diabetes-related cardiovascular diseases. Disclosure N.

    Abstract: Impaired adipose tissue (AT) function closely associates with obesity, type 2 diabetes and nonalcoholic fatty liver disease (NAFLD) . Mitochondrial oxidative phosphorylation (OXPHOS) capacity of AT improves after weight loss surgery. However, it is not clear if the improvement is affected by the presence of NAFLD before surgery. We examined 52 severely obese people exhibiting no histological liver disease (OBE_CON) , simple steatosis (OBE_NAFL) or steatohepatitis (OBE_NASH) before (0 weeks) , 12 and 52 weeks after bariatric surgery. Whole-body insulin sensitivity was measured by hyperinsulinemic euglycemic clamps. OXPHOS capacity of subcutaneous AT was assessed by high-resolution respirometry. Transcript levels of TNFα in AT were quantified by RT-PCR. Before surgery, OBE_NASH presented with lower insulin sensitivity and higher HbA1c compared to OBE_CON and OBE_NAFL (all p & lt;0.05) whereas OXPHOS capacity in AT was comparable between the groups. Maximum coupled respiration declined at week 12 by 17% from week 0 in OBE_CON only (p & lt;0.05) . From 12 to 52 weeks, AT maximum coupled respiration markedly increased by 82 and 49% in OBE_CON and OBE_NAFL (both p & lt;0.001) but only by 28% in OBE_NASH (p=0.05; maximum coupled OXPHOS at week 52: OBE_CON vs. OBE_NASH p & lt;0.05) . The changes in AT maximum coupled respiration from 12 to 52 weeks correlated negatively with changes in AT TNFα levels in OBE_CON (β=-0.83, p & lt;0.001) and negatively with changes in systemic C-reactive protein levels in OBE_NASH (β=-0.34, p & lt;0.05) . Maximal noncoupled OXPHOS yielded similar changes and correlations. In conclusion, in severe obesity, weight loss-related improvements in AT OXPHOS capacity may be mediated to a great extent by reduced AT inflammation in people without liver disease; however, with pre-surgery manifestation of NASH and worsening of metabolic control, residual systemic subclinical inflammation may attenuate the improvement of AT OXPHOS capacity after bariatric surgery.

    1452-P: Type 1 Diabetes Subphenotypes—A Cluster Analysis

    Abstract: Adult-onset type 1 diabetes (T1D) is a chronic disease with progressive beta-cell destruction. However, individuals with adult-onset T1D are metabolically dissimilar. We aimed to identify metabolically distinct groups in a comprehensively phenotyped cohort of individuals with recent-onset T1D. Participants with T1D (n=550) were split by presence of glutamic-acid decarboxylase antibody (GADA) into a GADA- (n=95) and GADA+ groups (n=455). GADA+ was clustered using partitioning around medoids based on fasting C-peptide, glucose, triglycerides and HDL resulting in 2 distinguished GADA+ clusters. All 3 clusters were compared at baseline (first year of diabetes diagnosis) and after five years of follow-up using ANOVA, chi-squared test and logistic regression adjusted for age and sex. The larger GADA+ cluster (n=285) with younger age, lower BMI and lower C-peptide was termed “classic T1D”. The other GADA+ cluster (n=170) combined features of type 1 and type 2 diabetes and was named “mixed T1D”. Patients of the “mixed T1D” cluster did not gain weight over 5 years (p=0.29), which was not the case for “classic T1D” cluster (p & lt;0.001, increased BMI with an effect size 0.07) and GADA-cluster (p=0.01, effect size 0.04) participants. The “classic T1D” cluster had the highest insulin sensitivity at baseline (p & lt;0.001) that sharply decreased during five years of follow-up. At five years, there was no difference in insulin sensitivity across the 3 clusters (p=0.78). There were no differences in HbA1c levels across clusters neither at baseline (p=0.48) nor after 5 years (p=0.64). Classic T1D participants reported a higher incidence of hypoglycemia (OR 4.92, 95% CI 1.9-13.5, p=0.001). The incidence of both distal peripheral sensory (OR 2.89, 95%CI1.05-8.29, p= 0.041) and cardiac autonomic neuropathy (OR 9.61, 95%CI 2.35-49.8, p= 0.003), was higher in “mixed T1D”. Based on rapidly available laboratory variables, individuals with recent-onset adult type 1 diabetes can be stratified into clusters with different clinical course and complication risk Disclosure K.Prystupa: Other Relationship; Berlin-Chemie AG.

    1573-P: Association of Thyroid Hormone Levels with NAFLD in Recent-Onset Diabetes

    Abstract: Nonalcoholic fatty liver disease (NAFLD) is a growing health concern associated with obesity and type 2 diabetes (T2D). Thyroid hormones are important regulators of lipid homeostasis. Indeed, people with hypothyroidism are at greater risk for NAFLD and it has been suggested that humans with T2D are more likely to develop hypothyroidism. However, little is known about the relationship of thyroid function with NAFLD in type 1 diabetes (T1D) and T2D. We hypothesized that (i) low free thyroxin (fT4) and high thyroid-stimulating hormone (TSH) levels are associated with increased hepatocellular lipid content (HCL) and (ii) that fT4 and TSH can identify persons at high-risk for hepatic steatosis in people with recent-onset diabetes. We examined people with T1D (n=358) or T2D (n=596) and 175 healthy participants of the German Diabetes Study (GDS). First, validation of the fatty liver index (FLI) against quantification of HCL by 1H-magnetic resonance spectroscopy revealed a close correlation (ß=0.715, p & lt;0.001; n=446). Second, FLI negatively correlated with fT4 in males (ß=−0.139, p & lt;0.01), but not in females with T2D (ß=−0.086, p=0.26). Likewise, TSH associated positively with FLI in males (ß=0.116, p & lt;0.05), but not in females with T2D (ß=−0.057, p=0.45). TSH and FLI were differently associated between males and females before (p & lt;0.05), but not after (p=0.82) adjustment for BMI. Finally, fT4 had a low diagnostic precision for steatosis (by FLI) as derived from the respective area under the receiver operating curve (0.57, 95% CI [0.53;0.62]; p & lt;0.001) in T2D and was not significant in other groups. TSH had no diagnostic precision for steatosis in any groups. In conclusion, FLI can be used as a surrogate measure of HCL in recent-onset diabetes. The correlation of FLI with lower thyroid function in male T2D suggests a sex-specific interaction between thyroid and liver lipid metabolism, which is mainly driven by body mass. Both, fT4 and TSH offer no relevant efficacy to detect steatosis at least in recent-onset diabetes. Disclosure N. Saatmann: None. M. Schön: None. O.P. Zaharia: None. M. Huttasch: None. K.
