Proliferative Glomerulonephritis With Monoclonal IgG Deposits in a Young Patient: A Case Report
Bibliographic record
Abstract
Proliferative glomerulonephritis with monoclonal IgG deposits (PGNMID) is a newly described entity that belongs to the class of disorders known as monoclonal gammopathy of renal significance (MGRS). The renal deposit in PGNMID is composed of monoclonal immunoglobulin (Ig). Microscopic findings typically show a non-fibrillar or non-microtubular pattern of Ig deposit without any organized structure. This entity affects adults and most patients present with nephrotic-range proteinuria and hematuria with or without renal failure. We report a unique case of PGNMID occurring in a young patient following a viral infection. The patient had significant proteinuria. There were no monoclonal proteins found in the serum. The renal biopsy was consistent with proliferative glomerulonephritis (GN) with monoclonal immune deposits. PGNMID is a novel form of GN that mimics immune-complex type GN on light and electron microscopy; thus, renal biopsy with careful attention to light-chain and IgG isotype staining is essential for diagnosis.

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.
