Single‐center experience with mycophenolate mofetil in pediatric renal transplant recipients
Bibliographic record
Abstract
Mycophenolate mofetil (MMF), a potent and specific inhibitor of guanosine nucleotide synthesis, is a new immunosuppressive drug used to prevent rejection in transplant patients. Extensive data on its utility and efficacy exists in adult patients but there is limited experience in pediatrics. Twenty-four children (14 male, 10 female; 2-19 yr of age), eight of whom had received living-related donor (LRD) transplants and 16 of whom had received cadaveric donor (CD) transplants, have been treated with MMF in our institution since September 1996. MMF was administered for a duration ranging from 13 weeks to 38 months, at an average dose of 600 mg/m2 (range: 200-1,000 mg/dose) every 12 h, for a total experience of 304 patient months. MMF capsules were used in 16 patients and/or pediatric suspension in eight. Five patients were switched to MMF from azathioprine as a result of rejection episodes or inability to taper prednisone, between 5 weeks and 3.5 yr post-transplant. All patients received prednisone, cyclosporin A (CsA), and induction therapy with anti-lymphocyte globulin (19 patients), anti-thymocyte globulin (one patient) or daclizumab (four patients). In 12 patients started on MMF at the time of CD transplant, five (42%) had an acute rejection episode. In seven who received a LRD transplant, one (14%) had an acute rejection episode. No patients who were converted to MMF were treated for acute rejection following conversion to MMF. One LRD graft was lost at 19 days following injury to the donor artery at the time of retrieval. At the last follow-up, the average creatinine level was 93 micromol/L and average urea level was 8.6 mmol/L. One patient developed epigastric distress. Three patients developed diarrhea/abdominal pain requiring dose adjustment. Five episodes of leukopenia and one episode of thrombocytopenia required dose adjustment. Two patients developed symptomatic cytomegalovirus (CMV) infection, one while on acyclovir prophylaxis. No malignancy has been encountered to date. Hence, MMF can be administered safely to children with good effect and with an acceptable side-effect profile.

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.
