A 24‐week dietary and physical activity lifestyle intervention reduces hepatic insulin resistance in the obese with chronic hepatitis C
Bibliographic record
Abstract
BACKGROUND/AIMS: Obesity- and virus-mediated insulin resistance (IR) are associated with adverse hepatic and metabolic outcomes in chronic hepatitis C (CHC). This study evaluates the tolerability and effects of a dietary and physical activity (PA) intervention in obese patients with insulin-resistant CHC. METHODS: Obese patients (body mass index, BMI ≥30 kg/m(2) ) with CHC were recruited prospectively. Non-diabetic patients with IR (homeostasis model assessment of IR, HOMA-IR >2.0) proceeded to a 24-week lifestyle intervention comprising pedometer monitored increase in PA (≥10 000 steps/day) and an individualised dietary plan. RESULTS: Ten non-cirrhotic and six cirrhotic patients [age 52 ± 8.5 years, BMI 35.9 (31.46-38.21)kg/m(2) ] were recruited, of whom all 16 (100%) completed the 24-week protocol. Increase in PA from 6853 (2440-9533) to 10 697 (7959-13566) steps/day (P = 0.001) and reduction in caloric intake from 2263 (1805.4-2697.0) to 1281 (1099.5-1856.3) kcal/day (equivalent to reduction of median 33% (25.3-49.8%), P < 0.001) were achieved. These behaviour changes led to a BMI reduction to 31.21 (28.72-36.10) (P < 0.001) and the HOMA-IR fell from 3.62 (2.75-4.87) to 2.08 (1.82-3.59) (P = 0.002). The hepatic insulin sensitivity index (ISI) improved significantly, but the skeletal muscle ISI did not. At week 24, 8/16 (50%) patients were no longer insulin-resistant (P = 0.008). CONCLUSIONS: This 24-week intervention reduced BMI and reversed IR in significant proportion of patients. Such adjunctive therapy may improve hepatic and metabolic status in obese insulin-resistant CHC.

How this classification was reachedexpand
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.
