A 25-year-old man is described with short stature, moderate mental retardation, an abnormal facial appearance, a webbed neck, skeletal abnormalities including proximal symphalangism of bilateral second through fifth fingers, mixed hearing loss, and slowly progressive, sclerosing nephropathy. He was large at birth with generalized edema, more pronounced around the jaw, neck and the upper part of the body, but became short with increasing age, and currently measures 143 cm (-4.9 SD). He had intermittent proteinuria and slowly progressive deterioration of the renal function. A biopsy of the left kidney showed global glomerular sclerosis with interstitial fibrosis. He was placed on maintenance peritoneal dialysis at age 17 years, and now on hemodialysis. His skeletal abnormalities included, in addition to proximal symphalangism, stenosis of the cervical canal, scoliosis, brachydactyly of the hands, hypoplastic hip joints, and pes valgus. Other abnormalities noted were a communicating defects of the diaphragm (surgically corrected), bilateral inguinal hernia and cryptorchidism. These clinical manifestations indicate a hitherto undescribed combination of manifestations and nephropathy.

A Japanese boy aged 9 years referred to our hospital because of steroid-resistant proteinuria. He had a 6-year history of unremitting proteinuria and was diagnosed as having minimal-change disease (MCD) by the repeated renal biopsies performed at the age of 3.5 years and 8.5 years, respectively. His proteinuria fluctuated ranging from 115 mg/100 ml to 645 mg/100 ml, and serum total protein ranged from 59 g/liter to 63 g/liter. The third renal biopsy at the presentation also revealed MCD. Thereafter he was treated with an anti-thrombocyte agent combined with an angiotensin converting enzyme inhibitor. Despite unremitting proteinuria of long duration, he did not have any complaints. At the age of 11.5 years, severe tubulointerstitial lesion was observed in the fourth renal biopsy. The fifth renal biopsy 6 months after the fourth finally revealed the lesion of focal segmental glomerulosclerosis (FSGS). Although the interpretation of his repeated renal biopsies were considered to be limited, these clinical observation suggested that his unremitting proteinuria of long duration might have been attributed to subsequent progression FSGS.

A 38-yr-old man with factor H dysfunction and unknown glomerular disease received first and second renal transplantations (Tx) from living-related donors. His examination showed a low percentage activity of factor H (31%). Factor H dysfunction has been known to be associated with type II or III membranoproliferative glomerulonephritis (MPGN), haemolytic uraemic syndrome and IgA GN. The first graft from his mother showed diffuse mesangial deposit of IgA. His son has had IgA GN and his data also revealed a low percentage activity of factor H (33%). He and his son both showed a low activity of C3. Moreover, his father, who was the donor of the second Tx, had a low percentage activity of factor H (25%), and presented with mild glomerular deposit of C3 at operation, while he has been healthy through his entire 67 yr of life. Each of them had a low percentage activity of factor H. These findings through three generations suggested the inheritance of factor H dysfunction. The patient presented with proteinuria 3 months after the first Tx. At the first biopsy 30 months after the first Tx, light microscopy revealed minor glomerular abnormalities with electron dense deposits in subepithelial, intramembranous and mesangial regions, while immunofluorescence showed massive glomerular deposits of C3. In the second biopsy 51 months after the first Tx, the glomerulonephritis developed mesangial proliferation and crescent formation, accompanied by more massive C3 deposit and intramembranous, mesangial and subepithelial dense deposits. He then required redialysis. At the second and third biopsies within 2 months after the second Tx, the renal graft showed similar findings to the first biopsy after the first Tx. He perhaps presented with a recurrence of complement-associated GN, showing an atypical form of MPGN after Tx. These findings suggest that factor H dysfunction may play an important role of a certain pathogenesis of GN.

Nephrotic syndrome is a condition commonly associated with end-stage renal disease secondary to diabetic nephropathy. It is usually associated with long-standing renal insufficiency, microalbuminuria, and overt proteinuria. We present a diabetic patient with acute oliguric renal failure and nephrotic syndrome. At presentation, he had a serum creatinine of 2.3 mg/dl, blood urea nitrogen (BUN) of 69 mg/dl, urinary protein excretion of 10.5 g/24 h, serum albumin of 1.3 g/dl, and a urine output < 400 cc/24 h. A renal biopsy was done and the renal pathology was compatible with early diabetic nephropathy. Despite intense diuretic therapy, the patient's renal condition did not improve, and peritoneal dialysis was started several months after diagnosis. After 8 months of dialysis therapy, the patient's renal parameters and urinary output spontaneously restored to normal limits (serum creatinine was 1.1 mg/dl, urinary albumin excretion was 411 mg/24 h, serum albumin was 4.3 g/dl, and normal urine output) and dialysis was discontinued. His renal function did not deteriorate after discontinuation of dialysis. We conclude that this patient's reversible acute renal failure and nephrotic syndrome were associated with minimal change disease and not due to diabetic nephropathy.

The prognosis of renal cholesterol crystal embolism (CCE) is poor, and many patients progressively develop to the end-stage of chronic renal failure. We herein experienced a 66-year-old male patient who recovered from hemodialysis (HD) shortly after an amputation of inflammatory toes. The patient complained of painful digital cyanosis at bilateral toes and livedo reticularis at right lower leg 4 weeks following aortic angiography. Laboratory examinations revealed eosinophilia and overt proteinuria (3.0 g/day). His serum creatinine level increased from 2.18 to 8.57 mg/dl over 6 weeks, and HD treatment was started. Treatment with simvastatin (5 mg/day) did not reverse renal failure and hypereosinophilia, but the amputation of right gangrene toes promptly increased urine output and eosinophilia completely disappeared concomitantly with a decline of C-reactive protein from 9.7 to 0.7 mg/dl. Serum creatinine level was also reduced to 3.46 mg/dl, and he eventually stopped HD totally after 32 sessions. This case suggested that the surgical amputation promptly recovered renal function. Reversal of inflammation may be more effective than lipid-lowering therapy for renal failure in our patient.

A 69-year-old man with proteinuria, hematuria and abnormal renal and hepatic function developed acute renal failure. His clinical and laboratory examinations showed splenomegaly, edema, anemia and polyclonal hypergammaglobulinemia with high IgG levels. Renal biopsy showed interstitial nephritis with predominant B cell and plasma cell infiltration without monoclonality. After corticosteroid treatment, the patient showed remission in clinical symptoms and laboratory findings. However, one year later, he developed mantle cell lymphoma (MCL) with typical lymphocyte markers of cyclin D1 and CD5. When evaluated retrospectively, this patient appeared to have multicentric Castleman's disease initially and developed MCL later.

A 52-year-old man was admitted to our hospital because of nephrotic syndrome. He had been monitored at our outpatient clinic for chronic hepatitis B, and had experienced histologically proven minimal change nephrotic syndrome at the ages of 40 and 51 years. Because of HBsAg positivity in his serum, steroid therapy was withheld in his earlier episodes and he recovered from nephrotic syndrome spontaneously. However, in the most recent episode the nephrotic syndrome was found difficult to control and the findings of renal biopsy showed FSGS, which is not expected in HBV-associated nephropathy. Finally, prednisolone was administered at the dose of 40 mg/day for four weeks, after which the dose was tapered. LDL apheresis was also administered three times because of the patient's incomplete response to prednisolone. His proteinuria was reduced from > 10 g/day to < 1 g/day, but the ALT levels and HBsAg titer increased. With stronger neominophagen C induction and very careful tapering of glucocorticoid, ALT levels and the HBsAg titer decreased. During the two-year period since the induction of glucocorticoid therapy, urinary protein excretion has been maintained at less than 1 g/gcr, and ALT levels and HBsAg titer have not increased. We conclude that attention must be paid to dose modification of steroid therapy and strategies without immunosuppressive agents such as LDL apheresis should be considered in the case of treatment of nephrotic syndrome with HB virus.

A sixty eight-year-old man was referred to our hospital for evaluation of hypertension and hypokalemia. His chief complaints were fatigability and weakness of the lower extremities. Atrophy of the right kidney was noted on computed tomography. The laboratory findings demonstrated massive proteinuria, markedly elevated plasma renin activity, hypokalemia, and renal insufficiency. Angiography showed total occlusion of the right renal artery. The patient was diagnosed as having nephrotic syndrome associated with renovascular hypertension. Treatment with candesartan, an angiotensin-II-receptor blocker (ARB), controlled both hypertension and proteinuria satisfactorily without worsening of his renal function. This is the first report on the effect of ARB on nephrotic syndrome associated with renovascular hypertension. Based on the results, ARB can be considered a promising agent for the treatment of patients with renovascular hypertension with massive proteinuria and renal insufficiency.

A 19-year-old man presented to the emergency department with a chief complaint of generalized body rash for two weeks. The rash began shortly after he initiated penicillin therapy for a sore throat diagnosed one week previously. He also complained of having dark urine and abdominal discomfort. His urinalysis revealed proteinuria and hematuria, and he was admitted for further evaluation and management. While in the hospital, he had an episode of hemoptysis. A renal biopsy was performed and revealed IgA deposition. In light of his systemic symptoms including rash and abdominal pain, he was diagnosed with Henoch-Schonlein purpura (HSP).

The authors report the first case of immunotactoid glomerulopathy (ITG) in a human immunodeficiency virus (HIV)-positive, hepatitis B- and C-negative African-American man who presented with hematuria and proteinuria. His initial presentation was compatible with HIV associated nephropathy, but on renal biopsy he was found to have ITG. He has been treated with highly active antiretroviral therapy and an angiotensin-converting enzyme inhibitor, but his proteinuria has not responded after 4 months of treatment. This case emphasizes the diverse glomerular lesions seen in HIV-positive patients and supports the use of renal biopsy to establish a diagnosis.
