Although spontaneous bacterial peritonitis is a frequent complication in the childhood nephrotic syndrome, it is very rare in adults with nephrotic syndrome. It frequently develops when the patients are either in relapse or receiving steroid therapy at the time peritonitis is diagnosed. We report an unusual case of a spontaneous bacterial peritonitis as the presenting feature in a 15-year-old male patient with nephrotic syndrome. He presented with diffuse abdominal pain and distension for 15 days. Abdominal paracentesis revealed the diagnostic laboratory findings of peritonitis, and the bacterial culture of the ascites showed a mixed growth of Escherichia coli and Pseudomonas aeruzinosa. His serum albu- min level was 1.6gldL and the amount of 24 hours proteinuria was 21.0g/day. Although he was treated with adequate antibiotics for 3 weeks, the peritonitis was more aggravated. We decided to insert a catheter into the peritoneal cavity for continuous drainage of the intractable ascites. Two weeks after drainage, the peritonitis improved as the peritonitis subsided, the proteinuria disappeared completely without a steroid therapy. Six months after spontaneous remission, the proteinuria have recurred, and the kidney biopsy then showed focal segmental glomerulorsclerosis.

A 33-year-old man was admitted with macroscopic hematuria and systemic edema appearing after an acute upper respiratory tract infection. On admission, hypertension, nephrotic syndrome were evident together with a decreased renal function. Renal biopsy showed markedly increased mesangial cells acompanied with increase of endocapillary cells including neutrophils. Immunofluorescence microscopy showed granular deposits of C3 and IgA. Electron Microscopy revealed so-called "hump" on the subepithelial area. These features were consistent with the coexistence of IgA nephropathy (IgAN) and post-infectious glomerulonephritis. It is not clear about the prognosis and the therapeutic regimen in the patient who develop above situation. Although the patient showed still persistent proteinuria, high dose steroid therapy was probably useful for improving the disease.

BACKGROUND: Monocyte chemoattractant protein- 1 (MCP-1) is produced by renal cells and an important mediator for monocyte/macrophage infiltration in various inflammatory renal diseases. In the process of renal disease, endothelin-1 is known to play an active role in cell growth, inflammation and fibrosis. The aim of this study was to investigate whether endothelin-1 regulates MCP-1 expression in cultured human proximal tubular epithelial cells. METHODS: Primary cultured human proximal tubular epithelial cells (PTEC) were incubated with or without various dose of endothelin-1. MCP-1 concentration in PTEC conditioned medium was measured by sandwich ELISA. MCP-1 mRNA expression was analyzed by Northern blotting. The NF-kB or AP-1 activity in response to endothelin-1 was measured by electrophoretic mobility shift assay. RESULTS: Endothelin-1 (10(-7) M) stimulated MCP- 1 production in PTEC, which was significant at 48 hours and various doses of endothelin-1 (10(-8)-10(-6) M) increased MCP-1 production from PTEC in a dose-dependent manner. Northern blot analysis revealed that endothelin-1 stimulated MCP-1 mRNA expression. Endothelin-1 (10(-7) M) stimulated both AP-1 binding activity and NF-kB binding activity up to 8 hour. Supershift analysis showed that p65 and p50 are major NF-kB subunit bound to the DNA probe and that c-Fos and c-Jun are major AP-1 subunit bound to the DNA probe. CONCLUSION: Our results suggest that endothelin- 1 may stimulate MCP-1 expression in proximal tubular epithelial cells through the activation of NF- kB and AP-1 binding activity.

Psoas abscess is rarely encountered with various etiologies and nonspecific clinical presentation, frequently resulting in delayed diagnosis, with increased morbidity and mortality. Two types of psoas abscess are recognized. The primary psoas abscess is generally following hematogenous dissemination of an infectious agent and the source is usually occult. The most frequently isolated pathogen is Staphylococcuss aureus. On the other hand, the secondary abscess is the result of local extension of an infectious process near the psoas muscle, especially in diabetes, malnutrition, alcoholism, and steroid abuse. A 83-year-old woman presented with high fever and progressive back pain. Abdominal CT scan showed bilateral psoas abscesses combined with lobulated kidney. Both cultures of blood and urine showed Klebsiella pneumoniae. By prolonged antibiotic treatment and abscess drainage, she showed clinical, and radiological improvement. Here, we report an unusual case of bilateral pyogenic psoas abscess complicated by acute pyelonephritis due to Klebsiella pneumonia.

The hemolytic uremic syndrome (HUS) is clinically characterized by microangiopathic hemolytic anemia, thrombocytopenia and acute renal failure. The unique cause has not been determined but some bacteria such as E. coli was regarded as the causative agent of HUS in infant. A 30-year-old male patient was admitted due to acute abdomen. In operating field, the periappendiceal abscess was found, so the appendectomy with the drainage of abscess was performed. Initial hemoglobin level was 16.2g/dL but abruptly developed anemia (12.6g/dL) and thrombocytopenia (27000/mm3) was detected at hospital day 3. The urinary outflow was totally absent, the serum creatinine was 12.8mg/dL and the LDH was 3,650IU/L. The peripheral blood smear showed strong evidence of microangiopathic hemolysis. We performed total plasma exchange and hemodialysis under the diagnosis of HUS. The patient's renal function was markedly improved and the last creatinine was 1.9mg/dl. To our knowledge, this is the first report of HUS associated with periappendiceal abscess in Korea. We present a case and the review of literature.

To determine the clinical outcome of patients with asymptomatic hematuria and/or proteinuria, the biochemical parameters and renal biopsies were reviewed. The patients with asymptomatic urinary abnormalities(n=193) were followed up in Kangnam St. Mary's hospital between 1981 and 1996 and their mean age was 38.8+/-14.0 years old, sex ratio of M:F 54:139, mean follow-up period 6.2+/-4.4 years. They were divided into three groups according to the first dipstick urinalysis findings:82 patients with isolated hematuria(H), 28 patients with isolated proteinuria(P), and 83 patients with concomitant hematuria and proteinuria(H+P). During the follow-up period, in the 82 patiets with H, 68.3% had persistent hematuria without proteinuria, hematuria disappeared in 23.2%, and 8.5% manifested proteinuria, none of the patients showed renal insufficiency. Of the 28 patients with P, 42.9% had persistent proteinuria, proteinuria disappeared in 39.3%, 10.7% manifested hematuria, and 7.1% showed renal insufficiency. Of the 83 patients with H+P, 51.8% had persistent hematuria and proteinuria, hematuria and proteinuria disappeared in 13.3%, 16.9% had persistent hematuria without proteinuria, 9.6% had persistent proteinuria without hematuria, and 8.4% showed renal insufficiency. Renal biopsy was performed in 79 patients. 75.9% of these patients had Ig A nephropathy, 11.4% had mesangial proliferative glomerulonephritis or mesangiopathy, and 8.9% had membranous proliferative glomerulonephritis. In conclusion, the most common cause of asymptomatic urinary abnormalities was Ig A nephropathy(75.9%) and all patients with isolated hematuria kept normal renal function, while some patients with proteinuria(7.1%) or concomitant hematuria and proteinuria(8.4%) progressed to chronic renal failure. Therefore, to monitor progressing to chronic renal failure, the patients with proteinuria(whether or not they showed concomitant hematuria) should be closely followed up.

BACKGROUND: The impact of hepatitis B or hepatitis C virus infection on renal transplantation outcome is controversial. The aim of this study is to assess the impact of hepatitis B and hepatitis C infection on kidney transplant over the long-term, 15 years and to compare infected patients with noninfected patients matched for factors possibly associated with graft and patient survival. METHODS: We analyzed 1,042 patients who underwent renal transplantation in period from March 1984 to Dec. 1998 including 107 with positive HBsAg (HBV(+) group), 81 with positive anti-HCV antibody (HCV(+) group) and 714 noninfected recipients (NBNC group). One hundred-forty patients who had not taken ani-HCV antibody screening test were excluded. The prevalence of chronic liver disease, the patient mortality, the patient survival rate and the graft survival rate were evaluated. RESULTS: The patient mortality during the period of follow-up was significantly higher in HBV(+) group(32.7%) than in HCV(+) group(9.9%) and NBNC group(8.4%). The cause of death related to liver desease was significantly higher in HBV(+) group(57.1%) than HCV(+) group(0%) and NBNC group(1.7%). Five year and 10 year graft survival rate were significantly lower in HBV(+) group(52.2 %, 39.2%) than in HCV(+) group(68.4%, 47.2%) and NBNC group(86.6%, 65.8%). Five year and 10 year patient survival rate of HBV(+) group(72.0%, 68.9%) was significantly lower than HCV(+) group(91.6%, 87.3%) and NBNC group(94.4%, 88.2%), but there was no significant difference in the patient survival rate between HCV(+) and NBNC group. CONCLUSION: Hepatitis B virus infection has a significant deleterious effect on the patient and graft survival of renal transplantation recipients. The poor survival rate was a result of the mortality from liver disorder. Hepatitis C virus infection also has a poor graft survival rate compared to NBNC group, but the patient survial rate is similar to NBNC group.
