Three hundred fifteen (315) elderly (> or = 60 years) patients with clinical renal diseases were evaluated for the evidence of glomerular diseases between November 1998 to June 2002. Glomerular diseases (GN) were observed in 20.6% (65/315) of the elderly patients. The age of the patients (male 56; female 9) ranged between 60-90 (mean 64.17 +/- 3.83) years. The clinical presentation of GN included: nephrotic syndrome 40 (61.5%), acute nephritic syndrome 19 (29.2%), rapidly progressive GN 4 (6.15%) and asymptomatic urinary abnormality 2 (3.0%). Overall, primary and secondary glomerular disease were seen in 47 (72.3%) and 18 (27.6%) elderly patients respectively. Idiopathic membranous nephropathy was the most common GN responsible for nephrotic syndrome in 11 (27.5%) of elderly patients. Diabetic Nephropathy related to type 2 diabetes mellitus was the second common cause 9 (22.5%) of nephrotic syndrome. Amyloidosis was noted in 6 (15%) patients. Nephrotic syndrome was related to leprosy in one patient. Amyloidosis occurred in association with multiple myeloma in 5 and carcinoma colon in 1 patient. Thus, primary and secondary GN were responsible for nephrotic syndrome in 60% and 40% of cases respectively. Endocapillary proliferative GN of post infectious etiology was the most prevalent (82.6%) form of acute GN in our elderly patients. Hypertension occurred in 78.2% of cases and edema in 69.5%. Pulmonary congestion (52.2%) and ARF (73.9%) were the dominant presenting feature of acute GN and 39% of patients required dialytic support. Glomerular crescents were seen in 4 (17.4%) patients with acute glomerulonephritis. Pauci-immune crescentic GN which is the commonest type of acute GN in the elderly in western countries was not observed in this study. Renal biopsy revealed mesangiocapillary GN (1) and mesangioproliferative GN (1) in two patients with asymptomatic urinary abnormalities. Thus, overall spectrum of glomerular disease in the Indian elderly population is similar to that of developed countries except in two ways: (1) post infectious endocapillary proliferative-GN was the commonest type of acute GN (2) rarity or absence of pauci-immune crescentic glomerulonephritis.

Abnormal proliferation of plasma cells and some monoclonal B cells frequently cause the secretion of monoclonal immunoglobulins or immunoglobulin fragments into the serum, causing monoclonal gammopathy, which leads to various diseases including renal diseases. Therefore, monoclonal gammopathy is frequently associated with kidney diseases, including glomerular and tubulointerstitial diseases. Glomerular disease, with the deposition of monoclonal immunoglobulins or their components, includes monoclonal immunoglobulin deposition disease (MIDD), AL or AH amyloidosis, type I cryoglobulinemia, proliferative glomerulonephritis with monoclonal IgG deposits (PGNMID), immunotactoid glomerulopathy, and fibrillary glomerulonephritis. In addition, tubulointerstitial diseases with the deposition of monoclonal immunoglobulins or their components are constituted by light chain (myeloma) cast nephropathy, light chain associated Fanconi's syndrome (light chain proximal [crystal] tubulopathy), and crystal-storing histiocytosis. In the present review article, we demonstrate the clinicopathological characteristics of MIDD, which is one of the representative diseases of plasma cell dyscrasias, and discuss various renal diseases with the deposition of monoclonal immunoglobulins or their components in glomeruli and the tubulointerstitium. We recommend that these renal diseases are arranged as one disease category, "renal diseases with deposition of monoclonal immunoglobulins or their components", in order to simplify the understanding of complicated diseases in plasma cell dysplasia.
