ICAM-1 and VCAM-1 on Human Umbilical Vein Endothelial Cells Infected by Hantaan Virus / 대한신장학회잡지

PURPOSE: Hemorrhagic fever with renal syndrome (HFRS) is an acute febrile disease caused by Hantaan virus. It is believed that various kinds of inflammatory mediators and cytokines might be involved in its pathogenesis. METHODS: We studied the expression of adhesion molecules, including ICAM-1 and VCAM-1 on Hantaan virus-infected human umbilical vein endothelial cells (HUVECs) with ELISA. RESULTS: Hantaan antigen increased gradually 48 hours after virus infection, ICAM-1 increased rapidly 3 hours after virus infection and VCAM-1 increased rapidly 4 hours after infection, a little later than ICAM-1. The patterns of the change of reaction were similar between the different concentrations of virus solution that had been adsorbed on HUVECs, but the expression of ICAM-1 or VCAM-1 was greater when HUVECs were infected with stock virus rather than when infected with tenfold diluted virus. CONCLUSION: We report the quantification using ELISA of ICAM-1 and VCAM-1 expression of HUVECs that have been infected by Hantaan virus. Increase of their expression would play an important role in the pathogenesis of HFRS.

A case of malaria in the kidney transplanted patients with maintenance immunosuppression / 대한내과학회지

Malaria infection is not uncommon in Korea these days, but there was no report of malaria infection in the patients who had been transplanted his or her kidney. With the immunosuppression, the atypical findings are frequent and make prompt diagnosis difficult. We report a case of malaria which showed atypical clinical course but treated successfully with conventional anti-malarial drug therapy. A 37 year old male patient were transplanted his kidney in Sep. 1997. He was admitted because of fever, which lasted 40 - 50 min every afternoon for 27 days. Numerous trophozoites were found on his peripheral blood smear, which was diagnosed as vivax malaria. Chloroquine and primaquine were given, and fever subsided next day. The patients has been stayed afebrile thereafter. We reported a case of malaria in the renal transplanted patient with the review of literatures.

Evaluation of Nutritional Status and Changes of Biochemical Parameters according to Protein Intake Levels in Hemodialysis Patients / 대한신장학회잡지

It is well recognized that malnutrition is one of the most important reversible factors contributing to mortality in hemodialysis patients. Until recently, highprotein diets were recommended for hemodialysis patients in an attempt to increase the synthesis of albumin and to promote the anabolism of body protein. However, the appropriateness of this recommendation has recently been questioned. This study investigated the effects of low and high protein intakes on the levels of serum albumin, total protein, BUN, and creatinine in 28 hemodialysis patients fed sequentially 1.0g(LPG) or 1.5g(HPG) protein and 30-35kcal/kg/ ideal body weight for four weeks. The HPG diet was associated with a significant increase in the levels of serum albumin, total protein, BUN, and creatinine however, the LPG diet was not. The serum levels of triglyceride and total cholesterol were in the normal range and did not changed by the diets. The levels of serum Hb, iron, and transferrin were lower than the normal values and did not changed by these two diets. Though individual considerations are recommended, it is possible that the high protein diet could increase the levels of serum albumin and total protein of the hemodialysis patients in Korea.

A Case of Nocardial Peritonitis in a Patient on Continuous Ambulatory Peritoneal Dialysis / 대한신장학회잡지

Norcardia is an aerobic, gram-positive, AFB positive filamentous organism which is frequently branching. Nocardial infection is usually opportunistic and is found in immunosuppressed patients during transplantation or anti-cancer chemotherapy. With the increasing number of AIDS, nocardial infection have been increasingly recognized as a serious human infection. Among patients on peritoneal dialysis, Nocardia is a rare cause of peritonitis : only one case has been reported in Korea. It is extremely important to make an early and correct diagnosis and treatment with susceptible antibiotics. We report here a case of nocardial peritonitis associated with Continuous Ambulatory Peritoneal Dialysis(CAPD) which was resistant to trimethoprim/sulfamethoxazole and has treated successfully with imipenem and amikacin.

Clinical Evaluation of Use of Permcath(R) in Patients with Poor Vascular Access / 대한신장학회잡지

Permanent vascular access is a prerequisite for successful treatment of patients with chronic hemodialysis. Although a number of strategies including native and synthetic arterio-venous fistulae are performed to create vascular access, they are often not available due to peripheral vascular diseases which are common in patients with diabetes and elderly patients. So, in spite of technical advance, vascular access for hemodialysis remains a significant problem confronting the nephrologists. Recently, Permcath(R) (double lumen silicone rubber catheter) has been introduced and can provide temporary access in patients whose native fistulas have not yet matured and permanent access in patients who have difficulty in creating a arterio-venous fistula. We investigated the availability and the clinical outcome of use of Permcath(R) as temporary or permanent vascular access. Total 16 catheters were placed in 14 patients who were admitted in Chung-Ang University Hospital between April, 1993 to March, 1996. Clinical course of the patients and outcome of the catheters were observed, retrospectively. The mean age of the 14 patients was 56 9 (39-67) years. The indications were exhausted peripheral access, poor vascular system for conventional access operation, and limited life expectancy. The median survival of the catheters was 80 weeks with a range of one week to 113 weeks. The one-year actuarial catheter survival rate was 67% and 44% at 2 year. The most common complication during use of Permcath(R) was infection, occurred in 5 patients (31.2%). The 5 catheters were removed because of complications of catheter such as infection or malfunction. We suggest that the Permcath(R) is a safe and durable temporary vascular access for patients with poor vascular system anticipating a long duration for arterio-venous fistula maturation and permanent access for patients who have exhausted peripheral access sites.
