Age- 55 yrs • Sex- Male • Known hypertensive and diabetic (5 yrs) • Presented with rapid deterioration of renal function • S Cr 1.6 mg% to 7.5 mg% over 4 months. • Urine examination- • Alb 2+ • 8-10 pus cells • 25-30 RBC

Kappa Lambda
Proliferative Glomerulonephritis, • Suggestion of Lupus nephritis • All serological tests done subsequently for SLE- Neg • Renal function progressively worsened over the next one and a half year.
Taken up for Live unrelated renal allograft transplant, standard immunosuppression. • Immediate post transplant period – uneventful. • Baseline S Cr 1.1-1.2 • Brain abscess after 2 months. • Mycophenolate stopped.
S Cr 2.3 gm%. • Acute graft rejection suspected. • Biopsy

FINAL DIAGNOSIS • Proliferative glomerulonephritis with monoclonal immunoglobulin deposits. • Recurrence in renal allograft. • Follow up • Autologous Stem cell transplant • Doing well reduction in proteinuria

The Ohio State University, • One patient who had denovo disease in the allograft • One patient had recurrent disease 1 yr after transplant
Why this case is presented? • Rarity of the condition • Early recurrence in the renal allograft • Importance of routinely performing kappa and lambda in renal biopsy. • Possibility of initial negativity of myeloma workup. • Recognizing and interpreting linear accentuation in diabetes.
