Clinical and pathological findings and the effects of therapy were investigated in 90 cases of nephrotic syndrome (NS) in elderly patients aged over 60 years. Membranous nephropathy was the most frequent type of primary NS. Amyloidosis and malignancy were common causes of secondary NS. Damage to the interstitium in the kidney, such as focal mononuclear cell infiltration, fibrosis and thickening of the small arterial wall in membranous cases, was often observed. Stage I and II based on electron-microscopy, were mainly observed in the patients, with membranous nephropathy. Prednisolone and immunosuppressive agent were most effective in these patients with membranous nephropathy. Prednisolone alone was the most effective on minimal change NS in the elderly. In the course of therapy, side effects such as pneumonia, sepsis due to fungus infections, such as aspergillus and candida, and infection, such as cytomegalovirus and herpes zoster, were more frequently observed, especially in the cases of MPGN, DPGN with moderate to severe mesangial proliferation, with a decline in renal function (Ccr < 50 L/day) and secondary NS. In secondary NS, the prognosis of amyloidosis was very poor and the findings pointed to a relationship between malignancy and nephrotic syndrome.

It is not certain whether the life expectancy of patients with membranous nephropathy is shorter than that of an age-matched healthy population. Forty-one patients (21 males, 20 females) aged between 16 and 70 years (average age: 33.3 years) were followed for 20 years. The patients were divided into two groups: group I (n = 18), consisting of patients in whom nephrotic syndrome persisted for more than two years or until death, and group II (n = 23), consisting of patients except for group I. The non-survival criteria are death or renal death. Twelve patients (29.3%) died during the study period. Eight patients belonged to group I and 4 to group II. The causes of death in group I patients were end-stage renal failure in 3 cases, ischemic heart disease in 1 case, subarachnoid hemorrhage in 1 case, malignancy in 2 cases, suicide in 1 case, and those in the group II patients were pneumonia, malignancy, cerebral softening, and diabetes mellitus, respectively. Eight patients who died in group I had a significantly longer difference between their actual life span (ALS) and life expectancy (LE) and a significantly smaller ratio of ALS to LE than the patients who died in group II (ALS-LE: -29.9 +/- 4.5 years in group I vs. -9.0 +/- 6.8 years in group II, p < 0.05, ALS x 100/LE: 22.5 +/- 8.0% in group I vs. 80.9 +/- 25.2% in group II, p < 0.05). In group I, the ratio of observed to expected death was 4.76 (95% confidence interval, 2.05 to 9.37) and significantly higher than that of the control population. In group II, however, the ratio was 1.09 (95% confidence interval, 0.30 to 2.80), and the difference from the control population was not statistically significant. These results suggest that longstanding nephrotic syndrome is associated with a shortened life expectancy in patients with membranous nephropathy.

We report the case of a 67-year-old man with allergic granulomatosis and angiitis (AGA; Churg-Strauss syndrome) who developed nephrotic syndrome during his clinical course and demonstrated membranous nephropathy on renal necropsy by electron microscopy. Following the development of symptoms of bronchial asthma accompanied by eosinophilia and mononeuritis multiplex, transbronchial lung biopsy confirmed a diagnosis of AGA. The patient died of pneumonia and disseminated intravascular coagulopathy, but necropsy revealed severe tubulo-interstitial damage with neutrophilic infiltration and, in half of the glomeruli, mesangial proliferation with subepithelial dense deposits. This paper thus describes a rare case of AGA complicated by a secondary type of stage I membranous nephropathy.

Clinical data and outcomes of 18 patients, aged 80 or older, on continuous ambulatory peritoneal dialysis (CAPD) during the last five years were reviewed. There were 12 males and 6 females, with a mean age of 85 (range 82-91 years) and median duration on CAPD of 31.5 months (range 2-58 months). End-stage renal disease was caused by nephrosclerosis in 9, diabetes mellitus and light chain disease in 2 each, and chronic glomerulonephritis, membranous nephropathy, and IgA nephropathy in 1 each, with the cause unknown in yet another 2 patients. Hypertension and angina were the commonest comorbid conditions observed. Peritonitis episodes occurred one per 10.8 patient-months, and necessitated catheter removal in 7 patients and reinsertion in 6 of them. Fourteen episodes of exit-site infections were seen in 8 patients, 2 developed pericatheter leak, and 1 had tunnel infection. Nine patients are continuing CAPD successfully, with a median duration of 29 months (range 11-57 months). One patient was transferred to hemodialysis, and 8 died. The causes of death were peritonitis (3/8), cerebrovascular accident (2/8), pneumonia (1/8), and septicemia (1/8), with the cause not known in 1 patient. Our survival rate of 80% at three years is encouraging, and we advocate CAPD as a successful alternative treatment modality in octogenarians.

We retrospectively investigated the prognosis and efficacy of various treatments in 58 Japanese patients with primary membranous nephropathy (MN). Patients were treated with prednisolone (PSL) + immunosuppressive (IS) agents (N = 22). PSL alone (N = 23), IS agents alone (N = 5) and aspirin or dipyridamole (N = 8). Overall, 25 patients (43.1%) achieved complete remission (CR), 11 (18.9%) achieved partial remission (PR) and 22 (37.9%) were non-responders (NR). The 10-year survival rate was 90% and the 10-year CR rate was 61.8% as determined by Kaplan-Meier analysis. There was no significant difference in the CR among treatment groups. Of the 22 patients in the PSL + IS group, 3 progressed to end-stage renal disease and 2, who were more than 65 years old, died of pneumonia. The clinical and histological data at renal biopsy did not significantly differ among the treatment groups. In conclusion, the overall prognosis of MN was excellent. Treatment with PSL and/or IS agents did not appear to be superior to treatment with aspirin or dipyridamole.

The management of membranous nephropathy first requires the recognition of whether the disorder is primary (idiopathic) or secondary. Next, a familiarity with its natural history and knowledge of our current capacity to predict those patients with the worst outcome is reviewed. Treatment options of those at risk of progression with immunosuppressive drugs is then discussed along with the required accompaniment of risk reduction strategies including idealization of the blood pressure, the use of angiotensin enzyme inhibitor therapy and perhaps dietary protein restriction. As well treatment directed at other complications of the disease process including the hyperlipidemia and hypercoagulability are considered as part of the management to reduce risks. Lastly, therapies directed towards preventing or reducing the complications of immunosuppressive drugs such as trimethoprim-sulfamethoxazole prophylaxis against pneumocystis carini pneumonia and biphosphonates to reduce bone mass loss from corticosteroid therapy are discussed.

A considerable permeability factor (or factors) derived from circulating T cells has a crucial role in proteinuria of nephrotic syndrome (NS). We attempted to remove pathogenic T cells through lymphocytapheresis (LCAP) in 6 patients with primary NS, 2 patients with minimal change nephrotic syndrome (MCNS), 2 patients with focal segmental glomerulosclerosis (FSGS), 1 patient with membranous nephropathy (MN), and 1 patient with MN and FSGS using Cellsorba (Asahi Medical Co., Osaka, Japan). LCAP was performed 2 times in 2 consecutive weeks and was followed with corticosteroid therapy with or without cyclosporine A in 5 patients. Two patients with MCNS, 1 with FSGS, and 1 with MN and FSGS showed a dramatic decrease of proteinuria (-30% and -94%) in their urine protein/creatinine ratio. Three out of 4 patients had a complete or partial remission (proteinuria <1g/day) within 8 weeks following immunosuppressive therapy. During the LCAP, T cells, especially activated T cells, decreased significantly in the response group. The other 2 patients, 1 with FSGS and 1 with MN, however, had no response to LCAP and following immunosuppressive therapy or low-density lipoprotein apheresis and suffered from end-stage renal failure or death by pneumonia. These results suggested that LCAP might have a beneficial effect on the treatment of NS, especially MCNS and in some patients with FSGS, despite varying responses to LCAP and concomitant immunosuppressive therapy.

The clinical significance of the glomerular tip lesion, characterized by podocyte prominence, capsular adhesion, and/or intracapillary foam cells at or adjacent to the urinary pole, remains unclear. It has been postulated that this lesion simply represents a response to heavy proteinuria, and cases of nephrotic syndrome with tip lesions, but no other histological abnormalities, may represent a form of minimal change nephropathy (MCN). However, others have reported that such lesions have a clinical course similar to that of primary focal segmental glomerulosclerosis (FSGS), and the tip lesion often is included among histological variants of FSGS. To determine whether tip lesions may be seen in MCN, we examined histological slides of kidneys from pre-1950 autopsies of patients with a diagnosis of lipoid nephrosis, a term that at that time comprised MCN and FSGS. Before the introduction of antibiotics and corticosteroid therapy, patients with nephrotic syndrome frequently died of sepsis. Eight such cases, with autopsies performed from 1924 to 1943, were identified in which no glomeruli had changes typical of classic FSGS or membranous nephropathy. More than 400 glomeruli were present in each case. Patient ages ranged from 3 to 45 years (six patients <11 years), all had marked edema (duration, 2 weeks to 21 months) and heavy proteinuria, and each died of sepsis and/or pneumonia (pneumococcal in six patients). Glomerular tip lesions were found in five of these eight cases (range, 3 to 26 lesions per case; 0.3% to 4.4% of total glomeruli present), with no predilection for the deep, middle, or superficial cortex. No tip lesions were seen in kidneys from autopsies of age-matched patients without a history of glomerular disease. These findings suggest that the glomerular tip lesion can occur in MCN and most likely represents a response to heavy proteinuria that is not disease specific.

An 88-year-old man with a 30-year history of type 2 diabetes and a 3-year history of chronic renal failure was admitted for evaluation of anasarca. On admission, findings of nephrotic syndrome and microscopic hematuria were observed. During the course of therapy, rapid deterioration of renal function occurred with the appearance of pneumonia. Irrespective of the therapy with hemodialysis and antibiotics, he died of respiratory failure. The autopsy showed a rare case of rapidly progressive glomerulonephritis (crescentic glomerulonephritis) superimposed on membranous nephropathy. This experience highlighted the importance of the differential diagnosis of non-diabetic glomerulopathy even in elderly patients with diabetes mellitus.

Spontaneous bacterial empyema (SBEM), a rare infectious complication among liver cirrhosis patients, is characterized by infection in the presence of pleural effusion without evidence of pre-existing pneumonia. The prevalence of SBEM in cirrhotic patients with hydrothorax is about 13%. However, it has previously not been reported in medical literature in patients with nephrotic syndrome. The most common microorganism identified is Escherichia coli, followed by Streptococcus species, Enterococcus species, Klebsiella pneumoniae, and Pseudomonas stutzeri. We present a patient with a history of nephrotic syndrome caused by membranous nephropathy, who received steroids and cyclophosphamide. He developed bilateral SBEM due to Aeromonas hydrophila and E. coli, which were isolated from the left- and right-side pleural fluid, respectively. The detailed clinical course, treatment, and outcome are described.
