Dietary Analysis of Kidney Transplant Patients Who Eat Korean Foods: Single Center Study / 대한이식학회지

BACKGROUND: Although nutritional problems associated with dialysis are well described, nutritional problems after renal transplantation have received little attention. Nutrition interventions play an important role in prevention and management of common health problems associated with renal transplantation such as obesity, hypertension, diabetes, and cardiovascular disease. METHODS: Sixty-four kidney transplant recipients who received post-transplant management at our hospital replied to the questionnaire. The questionnaire included 102 questions on the amount and types of Korean foods that they consumed last week. Nutritional elements of diet in renal transplant patients who consume Korean food were analyzed on the basis of the survey. RESULTS: The mean energy and protein of daily intake were 2,088+/-1,016 kcal and 75.5+/-38.2 g. Patients' diets were generally sufficient, but characterized by deficiencies in vitamin B2, vitamin D, niacin, calcium, and magnesium intake. CONCLUSIONS: Dietary advice is required with regard to intake of some nutritional elements for kidney transplant recipients who consume Korean foods. Their main nutritional problem is obesity after transplantation. Attention should be paid to prevention of nutritional imbalance.

A Case of Reversible Posterior Leukoencephalopathy Syndrome in a Patient with ABO Incompatible Kidney Transplantation / 대한신장학회지

Reversible posterior leukoencepalopathy syndrome (RPLS) was noted by a reversible syndrome of headache, altered mental status, seizure, and visual loss associated with findings indicating predominantly posterior leukoencephalopathy on imaging studies. We report a successful treatment of RPLS after secondary ABO incompatibility kidney transplantation with blood pressure control. A 41-year-old female whose primary kidney disease was chronic glomerulonephritis had graft failure developed after living donor kidney transplantation (1st kidney transplantation). She was admitted to our hospital for 2nd ABO incompatibility kidney transplantation. She had undergone 6 times of plasmapheresis and received additional two doses of rituximab (375 mg/m2) and intravenous immunoglobulin (0.5 g/kg) before kidney transplantation. She received basiliximab induction therapy, tacrolimus, steroid and mycophenolate mofetile after transplantation. The ABO antibody titer had been low (below 1:1) and evidences of rejection were not detected. Generalized tonic clonic type seizure, eyeball deviation, facial cyanotic change and loss of consciousness occurred at post operation 7th day. Several minutes later, she recovered her consciousness without disability and neurologic deficit. She did not represent attacks any more after we controlled blood pressure without withdrawal of immunosuppressants or dose reduction.

Clinical outcome of kidney transplantation in patients with diabetic nephropathy / 대한내과학회지

BACKGROUND/AIMS: Diabetic nephropathy is a growing cause of end-stage renal failure, and renal transplantation is considered the best option for survival in patients who experience such renal failure. Patients with diabetes are older and frequently have comorbidity, and only a minority of these patients is considered for renal transplantation. The survival rate of patients having diabetes treated with transplantation has improved, although the long-term prognosis has not been determined. This study examined the clinical outcome of renal transplantation in patients having diabetes compared to that in nondiabetic patients. METHODS: We compared diabetic (n=70) and nondiabetic (n=355) groups of patients for whom medical records were available for more than 3 months at our hospital from March 1998 to August 2008. RESULTS: The recipients were significantly older in the diabetic group (50.6+/- 10.5 vs. 39.8+/- 10.8 years), while donor age was significantly younger in that group (33.2+/- 9.0 vs. 37.5+/- 1.3 years). Cardiovascular events occurring after transplantation were more frequent in the diabetic group (11/70 vs. 10/355). Kaplan-Meier curves for cumulative survival of the renal allograft and patient survival revealed no difference between the two groups. The allograft survival rate in the diabetic group was 100% at 5 years and 79% at 10 years posttransplantation. In the nondiabetic group, the renal allograft survival rate was 98% at 5 years and 75% at 10 years. The patient survival rates did not differ significantly: 100% vs. 99% at 5 years and 91% vs. 91% at 10 years for the diabetic and nondiabetic groups, respectively. CONCLUSIONS: In our study, the long-term survival of renal transplantation in patients with diabetes equaled that of nondiabetic patients. Graft survival was also comparable between the two groups. Therefore, kidney transplantation may be another therapeutic option for end-stage diabetic nephropathy.

Leflunomide Treatment in BK Virus Associated Nephropathy after Renal Transplantation / 대한신장학회지

PURPOSE:BK virus associated nephropathy (BKVAN) affects 1-10% of kidney transplant (KT) patients and it produces a progressive destruction of allograft. Reducing immunosuppression is the only way to save the graft, while it needs tight monitoring of the graft rejection and graft survival is poorer in advanced case. Leflunomide has immunosuppressive effect and also antiviral activity. Addition of leflunomide may improve BK virus clearance and graft survival. METHODS:6 KT patients with biopsy proven BKVAN (Histological pattern B) were treated with leflunomide and reduced immunosuppression. All patients were monitored with serial determination of viral load in blood and graft function. RESULTS:BKVAN was diagnosed at 14 months (7-28) post transplant, at that time median serum creatinine concentration was 2.8 mg/dL (1.8-3.6). 12.5 months (6-16) later of leflunomide treatment, median serum creatinine was 2.3 mg/dL and no graft loss was found. CONCLUSION:Leflunomide therapy with reduced immunosuppression may be effective in the treatment for BKVAN.

A case of amebic colitis in a renal-transplant recipient / 대한내과학회지

Intestinal amoebiasis is caused by the protozoan Entamoeba histolytica. Amoebic colitis is usually acquired by ingesting contaminated food or water, but it can be associated with cell-mediated immunosuppression in organ-transplant recipients. We present a case of invasive amoebic colitis in a kidney-transplant recipient who was treated successfully with metronidazole and adjusted immunosuppressive therapy. The patient was a 49-year-old man who had undergone renal transplantation 15 years earlier. He complained of diarrhea accompanied by mild lower abdominal pain over five weeks, and the diagnosis of amoebic colitis was made with a colonoscopic biopsy. The colonoscopic findings showed multiple, round, scattered ulcerations throughout the colon, and trophozoites of E. histolytica were identified in the base of these ulcers. We treated his colitis with metronidazole and a reduction in immunosuppressive therapy.

Dysfunctional Contracted Bladder in Renal Transplantation / 대한이식학회지

PURPOSE: This report presents our experience of the renal transplatation of a long term dysfunctional contracted bladder and its outcome. METHODS: Between March 1996 and May 2006, 425 cases of renal transplantation were performed in our medical center. We found 14 chronic renal failure patients having dysfunctional contracted bladder (DFCB) that was diagnosed through the preoperative voiding cystourethrogram. DFCB was defined as the maximal urinary bladder volume less than 100 mL. No surgical or medical preparation was done before and after renal transplantation. In 8 out of 14 cases, extravesical ureteroneocytostomy (EVUC) was conducted and the Lich's EVUC was done for the other 6 cases. Double J ureteral stent was not employed in any cases. RESULTS: The mean age of the recipients was 41.4 years. The mean capacity of these bladder was 72.1 mL (range 20 to 100 mL). Of the 14 cases, thirteen had living donor related transplantation and one received cadaveric kidney. Postoperative complication was occurred in one case, which was bleeding. There was no evidance of urinary tract complication. All patient excluding of one patient who had the episodesof chronic rejection were stable throughout the entire follow up period. CONCLUSION: DFCB in renal translpantation had no adverse effect on successful outcome in transplant operation deposite no preoperative preparation, especially cadaveric donor transplatation, it may, however, need a delicate surgical skills to perform EVUC.

A Case about Use of Mycophenolate Mofetil in Acute Renal Failure Associated with Lupus Nephritis / 대한신장학회잡지

Mycophenolate mofetil (MMF) is a immunosuppressive agent increasingly used in organ transplantation and autoimmune disease. We report a case about use of MMF in SLE patient with rapidly worsening renal function. A 24-year old female was admitted due to 1-week history of generalized edema. Despite use of diuretics and conventional supported care, generalized edema was more aggravated and serum creatinine was elevated up to 5.2 mg/dL. Ten days after the initial admission, we started hemodialysis. After hemodialysis, improvement of generalized edema was achieved. Eighteen days after initial hemodialysis, we started corticosteroids and MMF because she shows persistent heavy proteinuria and oliguria. After use of corticosteroids and MMF, clinical improvement of renal complication was achieved in this patient. About 6 weeks later, we could discontinue hemodialysis. On two year follow up duration, she shows good renal function and no evidence of lupus flare-up signs. We suggest MMF is one of therapeutic options for patients with severe lupus nephritis, especially those refractory or intolerant to conventional cytotoxic agents.

A Case of Retransplantation in A Patient with Graft Loss Caused by Polyoma Virus Nephropathy / 대한신장학회잡지

Polyoma virus (PV) nephropathy is a known cause of graft loss after renal transplantation. In a renal transplant patient suspected of graft rejection, it is important to discriminate between PV induced interstitial nephritis and acute cellular rejection, because of similar pathologic findings. After the loss of the first allograft secondary to PV nephropathy, transplant graft nephroureterectomy before retransplantaton may have an influence in the recurrence of PV nephropathy. However, this question has not been completely resolved. Case: A 23-year-old male underwent first renal transplantation from his HLA haploidentical 25 year-old-sister. His renal function had been good with cyclosporine, steroid and azathioprine until 9 months after transplantation, when his serum creatinine level rose to 2.2 mg/dL. A renal biopsy revealed features of tubulitis and we confirmed PV nephropathy through a positive PV monoclonal antibody reaction to inclusion body. After gradual loss of graft function, he underwent hemodialysis. After 48 months of hemodialysis, the patient underwent cadaveric renal retransplantation without transplant graft nephroureterectomy. Thrombocytopenia and suspected delayed graft function occurred after 2 days of transplantation. A graft biopsy revealed thrombotic microangiopathy. Improved graft function was attained after a temporary stop of tacrolimus and ATGAM(R) bridging therapy. The patient is maintaining satisfactory graft function 33 months after retransplantation without clinical and serological evidence of recurrent PV infection.

Clinical trial of daclizumab in living renal transplantation / 대한내과학회지

BACKGROUN: Despite improvements in immunosuppressive therapy for use in renal transplantation, acute graft rejection remains a risk factor of chronic rejection and a major cause of graft loss and patient death. Recently, daclizumab, an anti IL-2 receptor monoclonal antibody has been shown to reduce the incidence of acute rejection. METHODS: To investigate the immunosuppressive effect of daclizumab and the incidence of acute rejection, we administered daclizumab intravenously (1 mg/kg of body weight within 24 hours before transplantation and once every other week afterward, for a total of 5 doses) in combination with cyclosporine microemulsion (CsA), steroid and mycophenolate mofetil (MMF) to 68 transplant recipients RESULTS: Among them 62 were undergoing their first transplantation and 6 were undergoing their second transplantation. 32 patients received living-related transplants and 36 patients received living-unrelated transplants: their HLA match were as follows:1 case with 1 Ag match, 13 cases with 2 Ag matches, 18 cases with 3 Ag matches, 3 cases with 4 Ag matches, 1 case with 5 Ag matches. The clinical characteristics of patients treated with daclizumab were as follows: 42 were male, 26 were female; the mean age of recipients was 42.94 +/- 11.2 years and that of donor was 34.1 +/- 9.9 years. The underlying renal diseases were glomerulonephritis (n=47), reflux nephropathy (n=6), diabetic nephropathy (n=12), polycystic kidney disease (n=2) and acute renal failure (n=1). During the observed period (17.41 +/- 4.34 months; min. 6 months, max. 26 months), 2 cases had acute rejection in the third month after transplantation and 1 case in the 6th month after transplantation, 1 case in the 24th month after transplantation (4/68, 5.8%). In the historical control, 20.8% of acute rejection (10/48) were noted in CsA, MMF and steroid regimen group and 36% of acute rejection (22/60) in CsA, azathioprine and steroid group. Serum creatinine level was 1.21 +/- 0.23, 1.31 +/- 0.25, 1.35 +/- 0.28 and 1.34 +/- 0.31 (mg/dL) during the 1st, 3rd, 6th month and 1 year after transplantation respectively. 10 patients developed herpes-zoster infection and 6 patients had CMV infection. 1 patient expired due to CMV pneumonitis on the 3 months after transplantation. The 2-year graft survival rate was 98.5% with daclizumab and 45 months graft survival rates were 92.9% and 89.3% for MMF group and azathioprine group respectively. CONCLUSION: Daclizumab, used in combination with CsA, MMF and steroid, reduced acute rejection episodes without serious short term side effects. Further observation is needed to evaluate the graft survival rate and uncover any long-term side effects.

Clinical Outcome of Kidney Retransplantation / 대한이식학회지

Renal transplantation is the optimal treatment for end stage renal disease and it has been improved through the development of operative methods and immunosuppressants. However some patients must receive dialysis or undergo retransplantation after a loss of the primary graft due to rejection or other causes. Recently the frequency of retransplantation has begun to increase gradually. Some articles have reported that retransplantation results do not significantly differ in comparison with initial transplantation results when living related donor kidneys are used. Our study focused on the outcome of 445 first transplantation and 12 retransplantation cases. The sex distribution of retransplanted patients was 11 male and 1 female. The mean age (yrs) for recipients was 32.3 at the first transplantation and 39.1 at the retransplantation. The underlying causes of end stage renal disease were presumed to be chronic glomerulonephritis in all retransplantion patients; the mean duration of graft survival (mo) for first transplantation was 77.92. The causes of previous graft failure were as follows: 10 due to chronic rejection, 1 due to recurrent glomerulonephritis, 1 resulted from a graft rupture due to a motorcar accident. The interval (mo) between graft failure and retransplantation averaged 6.7 and 9 out of 12 patients underwent regrafting within 1 year of their previous graft loss. Recipient-donor relationships in first transplantations were as follows: 9 were living related and 3 were living non-related. Recipient-donor relationships in second transplantations were as follows: 4 were living related and 8 were living non-related. Acute rejection within 1 month of transplantation occurred in 4 primary transplantation patients and 2 retransplantation patients. The incidence of acute rejection within 1 month was as follows: 23% of 445 first renal transplantation patients, 16.7% of 12 second transplantation patients. The 1 year and 2 year graft survival rate was 100% and the mean survival duration (mo) was 33 for retransp

A Case of Gastritis Cystica Profunda / 대한소화기내시경학회지

Gastritis Cystica Profunda is a rare condition showing multiple small cysts in the mucosa and submucosa of the stomach. These lesions have been found not only at the site of a gastroenterostomy but also in tbe stomchs of patients without any previous surgery. Recently, We witnessed a 56-year old e wale gastritis cystica profunda who had not undergone previous gastric surgery. The UGI and EGD revealed a 3.0 * 4.5 cm sized submucosal mass on the posterior wall of the antrum, and endoscopic ultrasonography(EUS) discovered a thickening of the third layer in which well-defined, round and nearly anechoic areas with posterior enhancement were gathered. They were thought to be cystic lesions. We report a case of gastritis cystica profunda without having had any previous surgery, the diagnosis was made based on findings from the EUS and histologic findings through surgery.
