Multiple Myeloma Presenting as Acute Kidney Failure Secondary to Lambda Light Chain Deposition
Bibliographic record
Abstract
Renal monoclonal immunoglobulin deposition disease (MIDD) is a rare disease defined by deposition of monoclonal light chains and/or heavy chains on basement membranes and vascular walls of the kidney. We describe a case of a 71-year-old woman with kidney failure secondary to monoclonal immunoglobulin deposition disease lambda in association with plasma cell dyscrasia. Her initial serum protein electrophoresis did not demonstrate a monoclonal protein, and classic cast nephropathy was absent on renal biopsy. However, lambda light chain deposits and associated changes confirmed MIDD. She achieved a very good partial response (VGRP) after 8 cycles of CyBorD (cyclophosphamide, bortezomib, dexamethasone) and her kidney function improved. This case highlights the importance of an early diagnostic with renal biopsy to prevent end-stage renal disease. A review of the existing literature and a discussion on the management of the disease is presented.

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.
