A rare case of crystalglobulinemia
Bibliographic record
Abstract
Crystalglobulinemia is an extremely rare complication of monoclonal gammopathy. We report a 49-year-old female who presented with acute kidney injury, microhematuria, and non-nephrotic range proteinuria. Eight weeks prior to presentation, she developed a lower urinary tract infection and acute kidney injury, but her creatinine failed to resolve after resolution of her symptoms with antibiotics. Kidney biopsy revealed a membranoproliferative pattern of injury, and numerous crystals were noted in the glomerular capillaries on electron microscopy. On immunofluorescence, positive staining for immunoglobulin G and kappa was demonstrated in the capillary lumen along the capillary walls. Based on the biopsy, a diagnosis of crystalglobulinemia was made. On serum protein electrophoresis, there was presence of a monoclonal band, which was too small to quantify. Urine immunofixation was negative. Patient was treated with cyclophosphamide, bortezomib, and dexamethasone regime and made a remarkable renal recovery.

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.
