  • Recently three proteins, playing central roles in the bidirectional transport of urate in renal proximal tubules, were identified: two members of the organic anion transporter (OAT) family, OAT1 and OAT3, and a protein that designated renal urate-anion exchanger (URAT1). Antibodies against these transporters are very important for investigating their expressions and functions. With the cytokine gene as a molecular adjuvant, genetic immunization-based antibody production offers several advantages including high specificity and high recognition to the native protein compared with current methods. We fused high antigenicity fragments of the three transporters to the plasmids pBQAP-TT containing T-cell epitopes and flanking regions from tetanus toxin, respectively. Gene gun immunization with these recombinant plasmids and two other adjuvant plasmids, which express granulocyte/macrophage colony-stimulating factor and FMS-like tyrosine kinase 3 ligand, induced high level immunoglobulin G antibodies, respectively. The native corresponding proteins of URAT1, OAT1 and OAT3, in human kidney can be recognized by their specific antibodies, respectively, with Western blot analysis and immunohistochemistry. Besides, URAT1 expression in Xenopus oocytes can also be recognized by its corresponding antibody with immuno-fluorescence. The successful production of the antibodies has provided an important tool for the study of UA transporters.

  • Purpose: The purpose of this study was to study the projected workforce of nephrology CNS in Korea. Method: Need models, ratio methods and expert opinion were used for projecting needs for the nephrology CNS. Result: In 2001, there are 28,046 ESRD(end stage of renal disease)patients, 304 renal replacement centers and 1695 nephrology nurses in Korea. the hemodialysis patients per hemodialysis nurse was 12. The number of nephrology CNS required to meet the demand for caring of ESRD patients in 2002, 2005 and 2020 was estimated at 616, 837 and 3105, respectively. 47 ESRD patients per nephrology CNS was revealed as a workforce standard before 2005. After 2005, It was 31 ESRD patients per nephrology CNS. Conclusion: This study founded the need to project future increments and development in supply of qualified nephrology CNS.

  • Peritoneal dialysis (PD) is associated with the development of various complications, such as exit site infection or peritonitis, and rarely, intestinal obstruction in prolonged PD patients with recurrent peritonitis. However, post-colonoscopy acute intestinal obstruction has not been reported in PD patients to date. Herein, we report a case of severe ileus after a colonoscopy without previous episodes of peritonitis in a PD patient. A 51-year-old man undergoing PD for 7 years visited our emergency department due to severe abdominal pain and vomiting after colonoscopic polypectomy. A simple abdominal radiography and abdominal computed tomography showed ileus with collapsed distal ileal loop. A peritoneal dialysate study revealed no evidence of peritonitis. The patient was treated with decompression therapy, and ileus was successfully treated without complications. This case suggests that it is not only necessary to prevent peritonitis, but also important to monitor the development of ileus after colonoscopy in PD patients.

  • Arrhythmias are complications of tunneled cuffed hemodialysis catheter insertion. Most complications associated with arrhythmias occur during guide-wire access, where the guide wire can cause traumatic damage to the conduction system of the heart. Conducting system injury in tunneled cuffed hemodialysis catheter insertion often involves the right bundle, causing right bundle branch block (RBBB). Transient RBBB with sinus rhythm is not usually accompanied by abnormal vital signs. However if patients already have left bundle branch block (LBBB), new onset RBBB can cause complete atrioventricular block (AVB), which can lead to fatal complications requiring invasive treatment. We report on a patient with LBBB who developed complete AVB during hemodialysis catheter insertion.

  • Nephrin, a structural molecule, is also a signaling molecule after phosphorylation. Inhibition of nephrin phosphorylation is correlated with podocyte injury. The PINCH-1-ILK-${\alpha}$-parvin (PIP) complex plays a crucial role in cell adhesion and cytoskeleton formation. We hypothesized that nephrin phosphorylation influenced cytoskeleton and cell adhesion in podocytes by regulating the PIP complex. The nephrin phosphorylation, PIP complex formation, and F-actin in Wistar rats intraperitoneally injected with puromycin aminonucleoside were gradually decreased but increased with time, coinciding with the recovery from glomerular/podocyte injury and proteinuria. In cultured podocytes, PIP complex knockdown resulted in cytoskeleton reorganization and decreased cell adhesion and spreading. Nephrin and its phosphorylation were unaffected after PIP complex knockdown. Furthermore, inhibition of nephrin phosphorylation suppressed PIP complex expression, disorganized podocyte cytoskeleton, and decreased cell adhesion and spreading. These findings indicate that alterations in nephrin phosphorylation disorganize podocyte cytoskeleton and decrease cell adhesion through a PIP complex-dependent mechanism.

  • Donepezil is a cholinesterase inhibitor used extensively to treat Alzheimer disease. The increased cholinergic activity is associated with adverse effects, therefore gastrointestinal symptoms, including nausea, vomiting, and diarrhea, are common. Hypokalemia is a rare adverse event that occurs in less than 1% of donepezil-treated patients. Although hypokalemia of mild and moderate grade does not present serious signs and symptoms, severe hypokalemia often results in prolonged hospitalization and mortality. Herein, we report a case of hypokalemia developed after the initiation of donepezil therapy for cognitive impairment.

  • Purpose: The purposes of this study are to examine and to compare factors causing stress and coping methods between nephrology nurses working in the Hospitals of University and the Hemodialysis Clinics. Method: Data were collected by a direct survey method using a questionnaire from August 13 to August 31, 2001. The sample of 137 nephrology nurses in the twenty-one Hospitals of University and 168 nephrology nurses in the twenty-six Hemodialysis Clinics were selected for a total sample of 305 nurses. Result: Stress according to general characteristics showed a significant difference in religion and in the level of satisfaction for their work. Stress score was the highest in the nurses whose religion was Buddhism(F=4.846, P=0.008) and in the group with 'dissatisfied' for the work in the Hemodialysis unit(F=3.193, P=0.014). The results analyzed coping method according to the general characteristics had a significant difference only in religion(F=16.237, P=0.000). The score for the coping method was the highest in Buddism. The score compared the satisfaction level for their work according to the hospital type, were 3.55 in the Hospital of University group and 3.35 in the Hemodialysis clinic group and these two values were significant different(p<0.05). The mean score of the stress nephrology nurses in the Hospitals of University is 2.79 and that of the stress nephrology nurses in the Hemodialysis clinics is 2.78 of 4 point scale. Among the factors causing stress, items related nursing work and conflict in nurse-patient relationship significantly caused more stress to the nephrology nurses in the Hospitals of University than to those in the Hemodialysis clinics(p<0.05). Conclusion: This study suggests that there were some differences in the stress and coping methods between nephrology nurses in the hospitals of University and the Hemodialysis clinics. Further study related to stress management program is needed to decrease stress and use effective coping methods.

  • The Korean Society of Nephrology participated in the task force team consisting of government authorities and civilian experts to prevent and control the spread of Middle East respiratory syndrome (MERS) in 2015. The Korean Society of Nephrology MERS Task Force Team took an immediate action and drafted 'the clinical recommendation for hemodialysis facilities' to follow when the first and the only confirmed case was reported in the hemodialysis unit. Owing to the dedicated support from medical doctors, dialysis nurses, and related medical companies, we could prevent further transmission of MERS infection successfully in hemodialysis units. This special report describes the experience of infection control during MERS outbreak in 2015 and summarizes the contents of 'the clinical practice guideline for hemodialysis facilities dealing with MERS patients' built upon our previous experience.
