Increased cyclosporine bioavailability induced by experimental nephrotic syndrome in rats
Bibliographic record
Abstract
Components of whole blood and plasma are highly altered during the presentation of nephrotic syndrome. The present study was aimed to explore the influence of nephrotic syndrome on the pharmacokinetics of cyclosporine (CsA) (10 mg/kg) administered i.v. to control or puromycin-induced nephrotic rats (P-NS). We found an increase in CsA bioavailability in the nephrotic group compared with controls. The area under the curve of blood CsA versus time (AUCiv) increased from 27.7 +/- 5.3 to 60.6 +/- 13.8 mug.h.mL-1 in control and P-NS rats, respectively. The AUCiv augmentation was positively correlated with cholesterol levels. On the other hand, the total body clearance was significantly lower (0.38 +/- 0.06 vs. 0.17 +/- 0.03 L.(kg body mass)-1.h-1) and the volume of distribution at steady state (3.70 +/- 0.52 vs. 2.85 +/- 0.32 L/kg) was significantly smaller in nephrotic rats as compared with control. These pharmacokinetic changes lead to a longer terminal half-life of CsA in P-NS rats (11.8 +/- 1.6 vs. 6.9 +/- 0.91 h). We conclude that the physiopathologic changes induced by the nephrotic syndrome in P-NS animals result in a significant increase in CsA blood exposure by both the decrease in drug distribution and the reduction in elimination rate of CsA.

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.
