This is the first reported case of a kidney transplant patient in Korea who developed cytomegalovirus and Nocardia pulmonary coinfection simultaneously with cytomegalovirus nephropathy. The patient had a history of end stage renal disease on peritoneal dialysis, diabetes mellitus and pulmonary tuberculosis. He underwent unrelated living kidney transplantation in China. About 5 months after transplantation, he developed high fever and rising serum creatinine for which he was admitted to hospital. Chest CT revealed consolidation in the left upper lung field and lung biopsy showed CMV infected bronchiolitis obliterans with organizing pneumonia. Culture of lung biopsy tissue grew Nocardia farcinica. In addition, he was found to have CMV infection in kidney tissue with positive CMV antigen assay of blood. This case emphasizes that CMV infection, through its effect on systemic immunity, may increase the risk of other opportunistic infection.

Chylothorax is defined as the accumulation of chyle-containing lymphatic fluid within the pleural space. The causes of chylothorax are various and usually attributable to 1 of 4 categories: malignancy, trauma (including surgery), miscellaneous disorders, and idiopathy. Occurrence of chylothorax in patients on hemodialysis is very uncommon and it may have resulted from multiple iatrogenic vascular trauma conducive to venous thrombosis and stenosis when hemodialysis catheters required frequent changes or long term indwelling. Local thrombosis and stenosis may increase the venous hydrostatic pressure and hinder the discharge of thoracic duct lymph into the venous system. Hence, chylous lymphatic fluid leak into the pleural space. Treatment of chylothorax may range from nonoperative management to elective surgery. We report a case of a patient on hemodialysis who developed chylothorax secondary to a subclavian vein stenosis without any other symptoms such as arm edema and successfully treated with nonoperative management.

IgA nephropathy can occur commonly in alcoholic liver cirrhosis and is the most common form of secondary IgA nephropathy. Defective clearance of IgA-containing complexes by liver is thought to contribute to the development of IgA nephropathy in alcoholic cirrhosis. Although IgA deposition is found up to 64% in autopsy cases of alcoholic cirrhosis, most patients have mild clinical symptoms, and nephrotic range proteinuria occurs rarely in these patients. We report a case of IgA nephropathy with a membranoproliferative pattern that is detected with unusual massive ascites in a patient with alcoholic liver disease. A 60-year-old male patient was referred to our hospital for evaluation and management of abdominal distension. Abdominal ultrasonographic findings were compatible with diffuse liver cirrhosis with splenomegaly and large amount of ascites. He had nephrotic range proteinuria, azotemia, hyperlipidemia, and hematuria in dipstick. Renal biopsy performed under the impression of acute nephritis revealed mesangial and endocapillary proliferative glomerulonephritis with double contour of capillary loop. Immunofluorescence findings showed mesangial IgA and C3 deposit, compatible with IgA nephropathy. He was treated with high dose steroid, and steroid was tapered during 2 months. Steroid treatment induced complete remission state, and ascites was resolved.

Acupuncture therapy has been widely performed by staffs of oriental medicine in Korea, and intramuscular stimulation (IMS) therapy has been introduced recently and used for controlling myofascial pain in the field of orthopedics, rehabilitation, and pain clinics. To penetrate human tissues, relatively long needles are used in both procedures and these these may have some risks to puncture blood vessels. However, there were few reports about sequelae or complications after such procedures in Korean literatures. Recently, we experienced two cases of perirenal hematoma in patients without blood coagulation abnormalities (one case induced by acupuncture in oriental medicine clinic, and the other case induced by IMS in orthopedic clinic and was also accompanied by perirenal abscess).

Renal pelvic and periureteral varices are rare cause of hematuria. On the intravenous pyelography, periureteral varices show a scalloped corkscrew-like appearance to the ureter without evidence of proximal obstruction. The cause of these varices includes renal vein thrombosis, obstruction of the inferior vena cava, congenital anomalies of the inferior vena cava or renal veins, infection, malignancy and nutcracker syndrome. We report a case of Periureteral Varices Diagnosed by Intravenous Pyelography caused by nutcracker syndrome.

An outbreak of rapidly progressive renal failure was observed in Belgium in 1993 and was related to a slimming regimen involving Chinese herbs. Extensive interstitial fibrosis with atrophy and tubular loss was the major histological lesion. Aristolochic acid has been suspected to be responsible for nephrotoxicity. The use of Chinese herbal medicines is very popular in Korea. We report the presence of a nephrotoxic compound in herb medications, which led to end-stage renal failure in a patient with complete remission state of minimal change disease. The typical and sequential pathologic changes in our patient following the consumption of herbs suggest possible relationship to herbal medicines, and end-stage renal disease, despite the fact that a cause-and-effect relationship cannot be automatically inferred.

It has been reported that paroxysmal nocturnal hemoglobinuria (PNH) kidneys are prone to urinary tract infection, variable functional or anatomical abnormalities, renal venous or intrarenal microvascular thromboembolic events, and variable courses of renal failure. Acute renal failure which is rarely developed in PNH patients is often associated with infection, hemolytic crisis or thrombotic complications. A 40-year-old man, who has been treated as iron deficiency anemia and duodenal ulcer for about 2 months, presented with urinary tract infection, intravascular hemolytic anemia, cholestasis, thrombocytopenia, and acute renal failure. Subsequently he showed progressively aggravating azotemia and refractory hypervolemia during evaluation, and then he eventually was diagnosed as PNH. So, we report a case of PNH which was diagnosed due to the advent of acute renal failure possibly due to hemolytic crisis precipitated by urinary tract infection and documented by flow cytometry, kidney magnetic resonance imaging, and renal biopsy.

BACKGOUND: Although the incidence has decreased markedly, mortality from uremic pericarditis still remained high at 8-10% due to hemodynamic compromise. Moreover, it is difficult to diagnose and discriminate from other causes of pericarditis such as tuberculous pericarditis in its early stage. The aim of this study was to analyze the factors that were related to the development of uremic pericarditis and factors that could distinguish it from other causes of pericarditis. METHODS: Eighteen patients who received pericardiocentesis due to uremic pericarditis from 1996 to 2005 in Korea university hospital were enrolled. All patients were diagnosed as severe uremic pericarditis by echocardiography. And as a comparison group, 37 patients with tuberculous pericarditis and 20 patients with malignant pericarditis were also enrolled. Analysis of the factors that were related to the development of uremic pericarditis or comparison of clinical, biochemical factors in uremic, tuberculous or malignant pericarditis were also done. RESULTS: In uremic pericarditis, the proportion of patients with peritoneal dialysis was higher (55.6%). The amount of pericardial effusion showed a positive correlation with the duration of dialysis, whereas showed negative correlation with hemoglobin and cholesterol levels. Pericardial fluid ADA was significantly higher in tuberculous pericarditis and pericardial fluid glucose was higher in uremic pericarditis. No specific factors that were related to the development of pericardial tamponade were identified. CONCLUSION: The development of severe uremic pericarditis might be related to poor nutritional status. In the early stage, ADA and glucose levels in pericardial fluid could be useful in distinguishing uremic pericarditis from tuberculous pericarditis. Prospective studies that enroll large patient population can be helpful in identifying factors that are related to the development of uremic pericarditis or tamponade.

PURPOSE: The leading cause of death of end-stage renal failure is cardiovascular disease. Elevated cardiac troponin T (cTnT) is associated with the high incidence and prevalence of cardiovascular disease and increased mortality and morbidity. Therefore the aim of this study was to examine the distribution of cTnT in continuous hemodialysis patients and clinical significance of elevated cTnT. METHODS: We studied 183 asymptomatic patients who were undergoing chronic continuous hemodialysis treatment. Predialysis blood samples also used to measure hematocrit, albumin, total cholesterol. We evaluated the history of coronary artery disease and the etiologies of renal disease using chart reviews and patients interviews and cardiac status were determined by electrocardiography, two-dimensional echocardiography and coronary angiography. Predialysis cTnT was measured by a second-generation assay, Elecsys 1010 and we considered patients with serum cTnT>0.1 ng/mL as positive. RESULTS: Forty two patients (23%) had cTnT greater than 0.1 ng/mL. Ischemic heart disease was observed in 18.6% (34/183), diabetes mellitus (DM) in 53.6% (98/183), hypertension in 92.3% (169/183) and left ventricular hypertrophy in 67.2% (123/183). cTnT revealed significantly higher level in the patients with age over 60, male, DM, pulse rate over 60 mmHg, ischemic heart disease (IHD), hematocrit under 36% and albumin under 3.7 g/dL. cTnT levels significantly correlated to ischemic heart disease, DM and male. CONCLUSION: In hemodialysis patients, cTnT level is related to age, sex, DM, pulse rate, IHD, hematocrit and albumin. A prospective study is necessary to provide information on the effect of correcting the controllable factors on cTnT level and cardiovascular mortality in maintenance hemodialysis patients.
