Abstract PDF: Leptospirosis is a spirochetal infectious disease caused by Leptospira interrogans, and may vary in degree from an asymptomatic infection to a severe and fatal illness. The kidney is one of the principal target organs of Leptospira. Renal disorders caused by Leptospira infection vary from an abnormality in urinalysis to acute kidney injury (AKI). Incidence of AKI in severe leptospirosis varies from 40% to 60%. AKI reflects the severity of leptospirosis and is generally accompanied by cholestatic jaundice. The pathophysiology of AKI in leptospirosis consists of hypovolemia, direct tubular toxicity, and rhabdomyolysis. Most patients with acute leptospirosis experience severe myalgias, and show laboratory evidence of mild rhabdomyolysis. However, occurrence of severe rhabdomyolysis is rare. We report here on a patient with leoptospirosis, who had severe rhabdomyolysis and acute kidney injury without jaundice.

Nontuberculous mycobacterial infections are a rare, but clinically important cause of infections in continuous ambulatory peritoneal dialysis (CAPD) patients. This is typically suspected when a patient does not respond to treatment with the usual antibiotics. We describe here a case of Mycobacterium abscessus exit site infection with abdominal wall abscess formation that was associated with CAPD, which required peritoneal catheter removal, surgical debridement of the abscess and long term antibiotic therapy.

Abstract PDF: Clinical study was carried out on the 64 hemodialysis patients (HD) with chronic renal failure who had been treated from December 1992 to July 1993 in Yeungnam University Hospital. The following results were obtained. In hematologic parameters, MCH was 28.8±2.0 pg, and MCV was 92.4±4.7 fl. Result revealed normochromic and normocytic anemia. Mean values of serum ferritin were 657.4±292.0 ng/ml in men and 511.5±370 g in women. Mean values of serum iron were 145.5±63.7 µg/dl. Mean values of transferrin saturation was 61.6±28.4%. Serum ferritin, serum iron and transferrin saturation were higher in HD group than normal reference. In erythropoietin treatment group, Hb and Hct were significantly higher than non-erythropoietin treatment group. Amount of transfusion was significantly higher in non-erythropoietin treatment group than erythropoietin treatment group (p<0.05). Values of iron, transferrin saturation were significantly higher in abnormal liver function test (LFT0 hemodialysis group than normal LFT group (p<0.05). Transfusion amounts revealed positive correlation with ferritin (r=0.4675), transferrin saturation (r=0.3823) and iron (r=0.3386) (p<0.05). In conclusion, erythropoietin treatment can reduce requirement of blood transfusion and transfusion related side effects such as iron overload, hemosiderosis and hemochromatosis.

One Case of Acute Renal Failure with Toxic Hepatitis Caused by Bile Juice of Cyprinus Carpionudus.: Shie Hwoa Park, Kyeung Woo Yun; Yeungnam Univ J Med. 1987;4(2):159-163. Published online December 31, 1987; DOI: https://doi.org/10.12701/yujm.1987.4.2.159

Abstract PDF: The toxic effect of carp bile is well documented since earlier times but its exact mechanism of toxicity is unclear till now. Recently we have experienced a case of acute renal failure with toxic hepatitis in a 32-year-old man who ingested raw carp bile. He suffered from abdominal pain, nausea, vomiting and diarrhea, which occurred 3 hours after the ingestion of raw carp bile juice. Hematuria, proteinuria, oliguria and jaundice developed subsequently. 9 times of hemodialyses was performed and hepatitis was treated by conservative measure. The patient was discharged after 17 days of hospitalization. About 1 month after carp bile ingestion, no sequelae was detected. The authors report a case of acute renal failure due to carp bile juice ingestion with review of literature. Further study in needed as to the toxic substances of carp bile and pathogenesis.

Abstract PDF: Since Combes' first description of hepatitis B virus associated membranous glomerulonephritis, many reports have shown a strong association of hepatitis B virus infection with various types of nephropathies, especially membranous glomerulonephritis and membranoproliferative glomerulonephritis. Recently, the authors experienced a case of membranoproliferative glomerulonephritis, type I in a 16-year-old male patient with persistent HBs and HBe antigenemia. One year prior to admission the patient was told of hepatitis at routine check, but he remained asymptomatic throughout. He was admitted to our hospital with chief complaints of proteinuria and microscopic hematuria found on routine urinalysis. Liver and kidney biopsy revealed chronic persistent hepatitis and membranoproliferative glomerulonephritis type I, respectively. We report a case of hepatitis B virus associated nephropathy with review of the literatures. Considering the endemic nature of hepatitis B virus infection in Korea, the incidence of hepatitis B virus associated nephropathy would be proportionally high in comparison with those of other countries. So, the importance of this entity merits special consideration in our country. Further study concerning pathogenesis, epidemiology, and treatment may be needed.

Abstract PDF: Behcet's disease was originally described as a triple symptom complex of oral aphthous ulceration, genital ulceration, and hypopyon iritis. It is now known to have a wide systemic manifestations. Among them, the central nervous system involvement should be diagnosed earlier because of it's lethal potential. Recently the authors experienced a case of Behcet's disease with CNS involvement. A 51-year-old female patient was admitted due to deterioration of mentality and generalized ache since 2 years prior to admission. The findings on physical examination were compatible with Behcet's disease, but without cerebrospinal pleocytosis. The manifestations were improved with medications of prednisolone, chlorambucil, colchicines, but relapsed relapsed 2 months later during subsequent tapering of prednisolone and chlorambucil. The patient is now on medication again. A case of Behcet's disease with CNS manifestations is reported with review of literature.
