Abstract/OtherAbstract:
|
A 57-year-old man with monoclonal gamma-globulinemia was admitted because of edema and proteinuria. A renal biopsy specimen showed lobular glomerulonephritis associated with deposition of material that was positive for IgG, C3, C1q, fibrin, kappa light chain, and lambda light chain but was not stained by Congo red. Glomeruli showed massive electron-dense deposits with two kinds of unusual, highly organized crystalline structures in the mesangial matrix and peripheral capillary loops. Clinically, the patient had nephrotic syndrome, microscopic hematuria, and hypertension. No Bence-Jones protein or cryoglobulin was found in the urine or serum. Immunoelectrophoresis of blood and urine revealed increased IgG-lambda paraprotein, but no free light chains were found. This case was not associated with amyloidosis, systemic lupus erythematosus, light chain deposition disease, cryoglobulinemia, or multiple myeloma. Immunotactoid glomerulopathy was diagnosed. Treatment with oral prednisone was effective for the management of nephrotic syndrome and renal dysfunction. Glomerular deposition of two kinds of microtubular structure in immunotactoid glomerulopathy has rarely been reported. |
