Pregnancy-Associated Parvovirus B19 Infection Causing Postinfectious Glomerulonephritis
Bibliographic record
Abstract
BACKGROUND: Postinfectious glomerulonephritis due to parvovirus B19 during pregnancy is not described in the literature. OBJECTIVE: A case and renal biopsy of postinfectious glomerulonephritis due to parvovirus B19 during pregnancy is presented. DISCUSSION AND CONCLUSIONS: The patient contracted "fifth disease," parvovirus B19, in the 10th week of pregnancy, and 2 weeks later developed hypertension, nephrotic range proteinuria, pleural effusions, and evidence of pure red cell aplasia. Serum parvovirus B19 IgM was positive; a renal biopsy was performed, revealing diffuse proliferative glomerulonephritis with immunofluorescent and electron microscopic changes consistent with postinfectious glomerulonephritis. Renal, hemodynamical, and hematological parameters returned to normal by the 16th week gestation, and the pregnancy proceeded without further complication to the mother, with term delivery of a healthy infant.

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.
