Application of Advance Directives for Patients with End Stage Renal Disease / 대한신장학회지

PURPOSE: In other countries, government guidelines related to chronic illness are being used to enhance supportive care of renal patients. In Korea, the number of old ages and hemodialysis patients with many complications has been increased. But we don't have any guidelines for palliative care of end stage renal disease. This paper reports a study exploring decisions about end-of-life treatment (e.g. cardiopulmonary resuscitation, renal replacement therapy) via routine use of advance directives in people with end stage renal disease undergoing hemodialysis. METHODS: 1) We revised advance directives in Seoul Medical Center. 2) We recommended the routine use of advance directives to patients who were treated in hemodialysis room of Seoul Medical Center from Jan, 2007 to Jun, 2007. So 35 patients were enrolled. 3) They had been interviewed about end- of-life treatment plans and filled up advance directives. RESULTS: 23 males and 12 females in total were enrolled. The advance directives include 18 questions about patient preferences for treatment of end-of-life. The majority of hemodialysis patients replied "I will follow doctor's decisions including cardiopulmonary resuscitation and renal replacement therapy" 8 females (67%), 15 diabetes (53%) and 11 geriatric patients above 60yrs old (52%), however, were against cardiopulmonary resuscitation. CONCLUSION: Routine use of advance directives will provide basic sources for end-of-life decisions in the care of end stage renal patients. And they would like to keep the high quality of life with the help of prepared therapeutic plan of care and well-dying presented advance directives.

Clinical Outcomes of Lamivudine Therapy and HLA Alleles in Chronic Hepatitis B Patients / 대한소화기학회지

BACKGROUND/AIMS: The human leukocyte antigen (HLA) system is an integral component of immune response. Highly polymorphic HLA genes may play a pivotal role in the response of antiviral therapy. We investigated the effects of HLA gene polymorphism on the clinical outcome of chronic hepatitis B patients who received lamivudine treatment. METHODS: Depending on their clinical response to lamivudine therapy, a total of sixty one patients were divided into following groups; non-responders, viral breakthroughers, relapsers, and seroconverters. HLA-A, -B, -Cw, -DRB and HLA-DRB1 alleles typing was performed on each group through the polymerase chain reaction and the sequence-specific oligonucleotide hybridization method. The distribution patterns of HLA-A, HLA-B, HLA-Cw, HLA-DRB, and HLA-DRB1 were then analysed. RESULTS: When non-responders were compared to the other groups, high frequencies in HLA-Cw*1, HLA-DRB1*4 and HLA-DRB*4 (p=0.015, 0.033 and 0.004 respectively) were evident. When seroconverters were compared to viral breakthroughers, high frequencies in HLA-A*2 and HLA-DRB*4 (p=0.048, 0.025 respectively) were evident. CONCLUSIONS: Our data suggests that HLA-A*2, HLA-Cw*1, HLA-DRB1*4 genes are related to the clinical outcomes of lamivudine treatment in chronic hepatitis B patients. These genes may be used in the prediction of the clinical outcome of lamivudine therapy in chronic hepatitis B patients.

A Cases of Paraganglioma in Bladder of Patient who Visited with Acute Renal Failure / 대한신장학회지

Pheochromocytoma is a catecholamines secreting tumor that usually appears in the adrenal medulla, sympathetic ganglia and extra-adrenal chromaffin tissue. About 10% of this disease is detected in the extra-adrenal chromaffin tissue which is called paraganglioma. The three major clinical symptoms of pheochromocytoma are headache, syncope and hypertension. Approximately 0.1% of hypertensive patients have pheochromocytoma. The extra-adrenal paraganglioma is found in abdominal sympathetic nerve ganglion or Zukerkandle's organ with great frequency, but it also appears, albeit rare, in the cervical ganglion, thoracic cavity, bladder, and pelvic cavity. Some cases of paraganglioma in bladder are being reported internationally, but domestic reports are rare. We report a case of paraganglioma originating in the urinary bladder of patient who visited with acute renal failure associated with malignant hypertension. We treated him with phenoxybenzamine and later with partial cystectomy. High blood pressure was well controlled and acute renal failure was resolved.
