A vexing case of bone pain in a renal transplant recipient: Voriconazole‐induced periostitis
Bibliographic record
Abstract
Immunosuppression increases the risk of opportunistic infections including fungal infections in solid organ transplant recipients. Voriconazole is used to treat invasive aspergillus infections but prolonged usage may rarely lead to periostitis. Increased plasma fluoride concentration leading to osteoblastic upregulation is thought to be the catalyst, and symptom reversal occurs with discontinuation of the offending agent. A renal transplant recipient who was on voriconazole for invasive aspergillosis developed diffuse debilitating symmetrical bone pain. Having ruled out other neurological, metabolic, and drug etiologies, voriconazole-induced periostitis was diagnosed. Increased plasma fluoride level was documented, but bone scan was non-specific. A therapeutic discontinuation of voriconazole and switch to posaconazole provided rapid symptom resolution. The patient accidently restarted voriconazole as an outpatient resulting in the same symptomology, and thus provided further evidence that this was drug related. Voriconazole-induced periostitis is a described entity in immunosuppressed solid organ transplant patients who are treated with a prolonged course of voriconazole. This case study is novel in that it demonstrates drug induced periostitis in a renal transplant recipient who developed debilitating periostitis within a short time after starting voriconazole and equally rapid resolution once it was discontinued. We conclude that patients treated with voriconazole should be routinely monitored for periostitis.

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.
