Chyluria with massive proteinuria: Do not reach for the biopsy gun!

We report on a patient presenting with persistent chyluria due to filariasis, whose clinical course was complicated by massive proteinuria and severe hypoalbuminemia. Treatment with dietary manipulation, antifilarials, and sclerotherapy resulted in successful reversal of the above abnormalities. It has been reported that chyluria is not associated with massive proteinuria, or that even in cases of massive proteinuria, hypoalbuminemia is not seen and implies a glomerular pathology.

Post-transplant complications, patient, and graft survival in pediatric and adolescent kidney transplant recipients at a tropical tertiary care center across two immunosuppression eras.

Background: We report pediatric PAKT patient and graft outcomes at a large tropical tertiary center spanning two transplant eras.
