Scrub typhus is a zoonosis transmitted by a chigger of trombiculid mite and manifested with fever, skin rash, myalgia, and hepatitis etc. The renal involvement of the disease is prese-ted with transient microscopic hematuria and/or proteinuria. However acute renal failure or meningoencephalitis is very rare. We report a case of scrub typhus manifested with acute renal failure, meningoencephalitis, and hepatitis. The patient was treated with doxycycline and continuous arteriovenous hemofiltration (CAVH) and recovered successfully.

Ornithine carbamoyltransferase (OTC) deficiency is a urea cycle disorder that causes the accumulation of ammonia, which can lead to encephalopathy. Adults presenting with hyperammonemia who are subsequently diagnosed with urea cycle disorders are rare. Herein, we report a case of a late-onset OTC deficient patient who was successfully treated with arginine, benzoate and hemodialysis. A 59-yr-old man was admitted to our hospital with progressive lethargy and confusion. Although hyperammonemia was suspected as the cause of the patient's mental changes, there was no evidence of chronic liver disease. A plasma amino acid and urine organic acid analysis revealed OTC deficiency. Despite the administration of a lactulose enema, the patient's serum ammonia level increased and he remained confused, leading us to initiate acute hemodialysis. After treatment with arginine, sodium benzoate and hemodialysis, the patient's serum ammonia level stabilized and his mental status returned to normal.

Light chain deposition disease (LCDD) is a systemic disorder characterized by the deposition of monoclonal immunoglobulin light chains (LCs) in various organs. As LCs are overproduced by an abnormal clone of B cells, LCDD is usually described in the course of plasma cell dyscrasias or other lymphoproliferative disorders. However, it can occur in the absence of any detectable hematological disorder even during prolonged follow-up. We experienced a case of 62-year-woman who presented generalized edema, massive proteinuria and renal insufficiency. The histologic findings showed nodular glomerular mesangial expansion and prominent ribbon like immunohistochemical staining for kappa-light chain in the glomerular capillary wall. There was no evidence of multiple myeloma in bone marrow biopsy specimen. Because she refused the intensive chemothrapy, low dose of prednisolone and cyclophosphamide were prescribed for 6 months. Her renal function was maintained relatively well without renal replacement therapy for 7 months. We report a case of idiopathic LCDD not associated with multiple myeloma or other plasma cell dysclasia.

Thin glomerular basement membrane nephropathy, also called benign recurrent hematuria, is characterized by diffuse thinning of the glomerular basement membrane and by hematuria. The present study was based on a retrospective review of 366 native kidney biopsies performed at Chungnam National University Hospital from January 1993 to November 1996. Fifteen of these cases satisfied the criteria for definition of thin glomerular basement membrane nephropathy, placing the incidence of the disease at 4.0%. The criteria for definition of the disease are 1) normal findings by light microscopy, 2) no deposits by immunofluorescent microscopy, and 3) diffuse thinning of the glomerular basement membrane by electronmicroscopy. The studied patients had a mean age of 35.8 years (range from 14 to 59) and included 12 females and 3 males. A positive family history was present in one case. All pateints were normotensive and had hematuria (four cases showed gross hematuria). Seven patients had mild proteinuria, but two patients showed proteinuria of nephrotic range. The serum creatinine level was within normal limits except one. Abnormalities were not observed in immunoglobulins, complement component, serologic tests (RA, ASO) and HBsAg. Renal biopsy findings by light and immunofluoroscent microscopy did not reveal any abnormalities but diffuse thinning of the glomerular basement membrane (range from 154 to 279nm) was observed by electronmicroscopy. With the above results, patients with idiopathic renal hematuria with normal renal function and normal blood pressure, thin glomerular basement membrane nephropathy should be considered.

Typhoid fever, although having undergone a progressive decline in incidence in Korea, has continued to occur sporadically in this country. Renal complications are usually noted in 2-6 percent of patients and various clinical features of renal complication have been reported. However, acute renal failure has been rarely reported. We did a renal biopsy in two patients with typhoid fever who exhibited clinical evidence of acute renal failure, such as oliguria, azotemia, and mentality change. Light microscopy showed that the glomeruli were intact and some of the tubules were dilated and lined by regenerating epithelium. There was mild interstitial edema. Immunofluorescent microscopy showed trace deposits of IgA in one case. Electron microscopy did not show eigther abnormal electron dense deposits or cellular proliferation. Fever and melena disappeared after chloramphenicol treatment, and with the cure of the typhoid fever, the renal symptoms also. Typhoid nephritis should be considered as a cause of acute renal failure when acute renal failure is developed in febrile patients.

Since 1976, several cases of acute renal failure and acute hepatitis after ingestion of raw carp bile have been reported. We experienced 1 case of acute renal failure and hepatitis after ingestion of the raw fish(Cyprinus carpio nudus) gall bladder. The patient ate raw fish gall bladder to improve the health. The size of the fish he ate was over 1 m and that of the gall bladder was about an egg size. The clinical manifestations were characterized by dizziness, headache, diffuse abdominal pain, both flank pain, nausea, vomiting and diarrhea. These symptoms were followed by gross hematuria, oliguria and jaundice. Elevation of blood urea nitrogen, creatinine, transaminases lasted for about 2 weeks. Biopsy of the kidney was performed 13 days after ingestion of raw fish gall bladder. The kidney pathology showed recovery phase of acute tubular necrosis. The patient recovered with conservative treatment.

We evaluated retrospectively the clinical characteristics of 26 adult nephrotic syndrome patients with minimal-change disease who were followed up for more than six months. Median follow up period was 23months. They consisted of 16 men and 10 women, and the mean age was 34.3 years (range 18-68 years). We administered prednisolone 1.0mg/Kg body weight to the patients for eight weeks and tapered it gradually. Complete remission was obtained in 22 (85%) patients treated with prednisolone and 54% of them reached complete remission in four weeks after beginning prednisolone treatment. Nine patients who initially responded to prednisolone therapy relapsed. Two of these nine patients showed single relapse and seven patients had frequent relapses during the study period. Cyclophosphamide or cyclosporin A was added when the patients did not respond to prednisolone and showed frequent relapse. Of the six patients treated with cyclophosphamide, four patients who were frequent relapsors and one patient who was a non-reponder to prednisolone went into complete remission. The other prednisolone non-responder did not remit. Microscopic hematuria was found in three patients and these patients showed elevated serum creatinine level at the time of diagnosis. Seven patients showed renal impairment at the time of renal biopsy. All of them recovered from renal failure after treatment. Six patients showed complete remission of nephrotic syndrome after prednisolone and/or cyclophosphamide treatment. There was no patient who showed a deterioration of renal function during the study period. In conclusion, complete remission was obtained in 85% of adult minimal change nephrotic syndrome patients and 41% of patients relapsed within one year after attaining complete remission. The serum level of creatinine and microscopic hematuria at the time of diagnosis were not associated with poor prognosis during the study period.

Severe hypernatremia is an important electrolyte disorder that has serious effects. The patient had no medical history. A. 20-year-old ingested bamboo salt for digestion and weight reduction according to the folk remedies posted on an internet website. She presented with vomiting and diarrhea over ten times per day. Her initial serum sodium concentration was 174mEq/L. Her symptoms improved rapidly with hypotonic saline infusion. She recovered completely without any sequelae in three days. Severe hypernatremia in a normal young adult with clear consciousness and normal renal function has not been reported in Korea yet. So we report a case of severe hypernatremia by excessive bamboo salt ingestion in healthy young woman.

BACKGROUND/AIMS: There has been controversy about the role of Toll-like receptor 2 (TLR2) in renal injury following ureteric obstruction. Although inhibition of the renin angiotensin system (RAS) reduces TLR2 expression in mice, the exact relationship between TLR2 and RAS is not known. The aim of this study was to determine whether the RAS modulates TLR2. METHODS: We used 8-week-old male wild type (WT) and TLR2-knockout (KO) mice on a C57Bl/6 background. Unilateral ureteral obstruction (UUO) was induced by complete ligation of the left ureter. Angiotensin (Ang) II (1,000 ng/kg/min) and the direct renin inhibitor aliskiren (25 mg/kg/day) were administrated to mice using an osmotic minipump. Molecular and histologic evaluations were performed. RESULTS: Ang II infusion increased mRNA expression of TLR2 in WT mouse kidneys (p < 0.05). The expression of renin mRNA in TLR2-KO UUO kidneys was significantly higher than that in WT UUO kidneys (p < 0.05). There were no differences in tissue injury score or mRNA expression of monocyte chemotactic protein 1 (MCP-1), osteopontin (OPN), or transforming growth factor beta (TGF-beta) between TLR2-KO UUO and WT UUO kidneys. However, aliskiren decreased the tissue injury score and mRNA expression of TLR2, MCP-1, OPN, and TGF-beta in WT UUO kidneys (p < 0.05). Aliskiren-treated TLR2-KO UUO kidneys showed less kidney injury than aliskiren-treated WT UUO kidneys. CONCLUSIONS: TLR2 deletion induced activation of the RAS in UUO kidneys. Moreover, inhibition of both RAS and TLR2 had an additive ameliorative effect on UUO injury of the kidney.
