Fasting and postprandial kidney haemodynamic effects of empagliflozin and linagliptin in mono‐ and combination therapy compared to gliclazide in overweight people with type 2 diabetes ( <scp>RACELINES</scp> ): A randomised, double‐blind trial
Bibliographic record
Abstract
BACKGROUND: Sodium-glucose cotransporter (SGLT) 2 inhibitors attenuate fasting glomerular hyperfiltration in people with type 2 diabetes (T2D). However, SGLT2-inhibition increases glucagon levels, which facilitate postprandial hyperfiltration. The impact of SGLT2 inhibition on protein-related hyperfiltration and postprandial (intra) kidney haemodynamic function is unclear. Moreover, the interaction with dipeptidyl-peptidase (DPP)-4 inhibitors, known to reduce glucagon levels and to affect meal-related factors modulating GFR, is unknown. AIMS: We aimed to assess the effects of empagliflozin and linagliptin in mono- and combination therapy compared to the initiation and intensification of SU-derivative gliclazide treatment on fasting and postprandial kidney haemodynamic function. MATERIALS AND METHODS: We compared three 16-week glucose-lowering strategies added to ongoing metformin monotherapy: (1) EMPA-LINA: 8-week empagliflozin 10 mg QD (EMPA0-8w) followed by the addition of 8-week linagliptin 5 mg QD (LINA8-16w); (2) LINA-EMPA: 8-week linagliptin (LINA0-8w) followed by the addition of 8-week empagliflozin (EMPA8-16w) versus (3) GLIC-GLIC: 8-week gliclazide 30 mg QD (GLIC0-8w) followed by the addition of 8-week gliclazide 30 mg (GLIC8-16w). We studied (intra) kidney haemodynamic interactions of this combination using iohexol and PAH clearance techniques to assess measured glomerular filtration rate (mGFR) and effective renal plasma flow (ERPF). RESULTS: and urinary albumin-creatinine-ratio 1.0 [0.4-1.9] mg/mmol). In the fasting state, EMPA0-8w (-13.2; -21.3 to -5.1 mL/min) but not LINA0-8w reduced within-group mGFR. EMPA8-16w (-10.2; -16.5 to -4.0 mL/min) but not LINA8-16w reduced within-group mGFR. Following a proteinload, EMPA0-8w (-11.4; -20.2 to -2.6 mL/min) and EMPA8-16w (-16.2; -22.9 to -9.4 mL/min) but not LINA0-8w or LINA8-16w reduced within-group mGFR. Versus the comparatorarm, fasting mGFR EMPA0-8w, EMPA8-16w and EMPA-LINA and postprandial mGFR EMPA8-16w and LINA-EMPA, were significantly reduced. mGFR reductions resulted from intrakidney efferent vasodilation rather than afferent vasoconstriction. CONCLUSION: In T2D people without CKD, the favourable kidney haemodynamic effects of empagliflozin persist in the postprandial state and are irrespective of concurrent use of linagliptin.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
