1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

backgroundCurrent prednisone dosing in the treatment of young patients with childhood-onset systemic lupus erythematosus (cSLE) is largely based on achieving balance between therapeutic efficacy and toxicity, with weight-based dosing a common clinical practice. Despite the widespread use of prednisone, few attempts have been made to improve its clinical dosing regimen, and response to prednisone therapy remains variable.

objectiveThe purpose of this study was to characterize the pharmacokinetic (PK) properties of prednisolone, the metabolite of the prodrug prednisone, in cSLE patients and explore the relationship between PK properties and cSLE disease activity.

methodsBlood samples were taken 1 hour before the morning prednisone dose and at 20, 40, 60, and 90 minutes, and 2, 3, 4, 6, and 9 hours from 8 patients (ages 12-28 years) after an 8-hour fast. The mean weight-adjusted daily prednisone dose, stable for at least 30 days pre-study, was 0.29 mg/kg/d. PK analysis of prednisolone was performed using noncompartmental analysis with WinNonlin. cSLE disease activity was measured using the British Isles Lupus Assessment Group index and Systemic Lupus Erythematosus Disease Activity Index.

resultsMean total prednisolone AUC(0-9), prednisone CL/F at steady state, and half-life were 1094 (range, 467-2404) ng/h/mL, 11 (range, 6.7-13.7) L/hr, and 2.6 (range, 1.3-3.9) hours. Mean total prednisolone AUC(0-9) normalized to prednisone dose by weight was 4361 (range, 1136-9580) ng/h/mL/mg/kg. Mean total prednisolone C(max) normalized to prednisone dose by weight was 1097 (range, 301-2211) ng/mL/mg/kg at 1.84 (range, 0.48-4) hours (T(max)). Patients on prednisone had interindividual variability in prednisolone AUC(0-9) (61% CV) and dose-adjusted AUC(0-9) (58% CV).

conclusionsInterindividual variability in systemic exposure to prednisolone in cSLE patients was observed.
