Effect of Combination of L-Arginine and L-Carnitine on Serum AGEs Level, Kidney and Endothelial Function in Patients with Chronic Heart Fa
Bibliographic record
Abstract
The aim of the study to evaluate the effect of combination of L-Arginine with L-Carnitine on GFR, serum AGEs level and endothelial function in chronic heart failure (HF) patients with preserved ejection fraction (HFpEF). Materials and Methods: 35 patients with mean age 60,1 [56,7; 77,3] years with an established diagnosis of HFpEF were enrolled. The patients were randomly and blindly divided into 2 groups: first (1st) group pts were treated with a combination of L-Carnitine and L-Arginine in addition to standard treatment; 2nd group pts – with L-Arginine in addition to conventional treatment. Standard laboratory blood tests, lipid profile, glucose, renal and liver function tests, serum advanced glycation end-product (AGEs) level, echocardiographic examination, flow-mediated dilatation (FMD%) were performed for all patients baseline and after 10 days of treatment. The glomerular filtration rate (GFR) was estimated using the CKD-EPI formula. Results: Median level of AGEs was 1.72 [1.34; 1.93] mg/ml. The level of AGEs was correlated with age (R = 0.71, p<0.05), disease duration (R = 0.69, p<0.05). After 10 days of treatment with a combination of L-Carnitine with L-Arginine mean AGEs was decreased by 13.1% in comparison with L-Arginine treatment group (p=0.0003). After the treatment in 1st group mean AGEs was significantly lower in comparison with the 2nd group (p=0.004). Baseline median level of GFR was 81.2 [72,1; 86,2] ml/min and correlated with disease duration (R = 0.71, p<0.05), AGEs level (R = -0.73, p<0.05). The inclusion combination of L-arginine aspartate with L-Carnitine contributed to the significant increase of GFR level (p=0.003). The median FMD% level was 6.2 [4.4; 7.9] % and correlated with age (R=-0.61, p < 0.05), GFR (R=0.54, p < 0.05). After the 10 days it had been established significant increasing of FMD% level on 47.9 % in 1st group (p=0.0005), and on 29.3 % in 2nd group (p=0.003). Endothelial function normalizing was achieved in 10 (66 %) pts of 1st group and in 9 (45%) pts of 2nd group (p=0.002). Conclusion: The combination of L-Carnitine, and L-Arginine improves kidney, endothelial function and contributes to decreasing of AGEs level in pts with HFpEF.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
