IgA Cutaneous Purpura Post–Renal Transplantation in a Patient With Long-Standing IgA Nephropathy
Bibliographic record
Abstract
BACKGROUND: IgA vasculitis is a small-vessel vasculitis caused by deposition of IgA antibodies in tissues. IgA nephropathy and IgAV have long been considered related conditions. OBJECTIVE: To assess the prevalence and implications of new-onset Henoch-Schönlein purpura (HSP) after renal transplant in patients with underlying IgA nephropathy. METHODS: The PubMed database was searched for keywords such as IgAV, IgA vasculitis, Henoch-Schönlein purpura, HSP, IgA nephropathy, and renal transplant. RESULTS: Two cases of new-onset IgA vasculitis post-renal transplant after stopping the prednisone or receiving seasonal influenza vaccine have been reported. We report the case of new-onset IgA cutaneous vasculitis in a renal transplant patient with IgA nephropathy after reduction in his prednisone dosage. CONCLUSION: The new development of cutaneous IgA vasculitis is unusual in renal transplant patients with IgA nephropathy. Despite these patients' being immunosuppressed, the presence of IgA vasculitis could signal the recurrence of IgA nephropathy.

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.
