From November 1998 to March 2000, two hundred patients over the age of 60 years (Elderly) with clinical renal disease were studied. 144 patients were between ages of 60-69 years, 46 between 70-79 years and 10 were above 80 years. The elderly patients (Male 165; Female 35) with renal disease constituted 11% (200/1816) of the total nephrology consultation during the study period. The clinical presentation included chronic renal failure (42.5%); acute renal failure (28%); nephrotic syndrome (14.5%); acute glomerulonephritis (7.5%); renal vascular disease (5%) and renal cystic disease (2.5%). Diabetic nephropathy, obstructive uropathy and hypertensive nephrosclerosis were the major causes of CRF, accounting for 80% of total CRF in the elderly. Chronic glomerulonephritis and chronic pyelonephritis (CPN) were less common and etiology of CRF was uncertain in 5.9% of cases. However, diabetic nephropathy was the commonest (49.4%) cause of chronic renal failure. We did not see a single case of ischemic nephropathy causing CRF in the present study. Prerenal ARF, obstructive uropathy and sepsis were contributing factors for ARF in 82% of the cases. Volume depletion due to gastrointestinal fluid loss and urinary tract obstruction on account of enlarged prostate were the leading causes of ARF in 20 (35.7%) and 8 (14.3%) cases respectively. Sepsis with or without multiorgan failure was the major (46.7%) cause of mortality in patients with ARF and overall mortality was 26.8%. The commonest (31%) cause of nephrotic syndrome was the idiopathic membranous nephropathy. Diabetic nephropathy related to type-2 diabetes mellitus was the second most common (24.1%) cause of nephrotic syndrome. Diffuse endocapillary proliferative GN of post infectious etiology was the commonest (73.3%) type of acute GN in our elderly patients. Renal cystic diseases were noted in 5 (ADPKD 3; Simple cyst-2) patients. Thus, overall spectrum of renal disease in our elderly patients is similar to that of developed nations except in two ways: (i) Endocapillary proliferative GN of post infectious origin was the commonest type of acute GN and (ii) Rarity or absence of ischemic nephropathy and atherosclerotic renal artery occlusive disease.

Mesangial expansion and glomerular basement membrane thickening characteristic of diabetic nephropathy recur in diabetic recipients of renal allografts from non-diabetic donors but progression to renal failure is minimally documented. Three female renal allograft recipients (aged 40, 62 and 73 yr), who developed end-stage renal disease (ESRD) due to recurrent diabetic nephropathy (two patients) and de novo diabetes (one patient) are reported. Onset of proteinuria, uncontrolled hypertension, azotemia, renal allograft pathologic findings and the need for hemodialysis were analyzed. None of the kidney donors (one cadaver, two living related) had known diabetes or perturbed glucose metabolism pre-transplantation. The three patients presented had different varieties of diabetes; type 1, type 2 and new onset diabetes after transplantation (NODAT). In each subject, proteinuria was detected by dipstick at a mean of 8.3 yr (range 8-9) post-transplantation and increased to the nephrotic range (3.7-4.8 g/day) inducing hypoalbuminemia and azotemia. A histopathologic diagnosis of allograft diabetic nephropathy was made in a mean of 11.7 yr (range 10-14), based on glomerular basement membrane thickening, nodular and diffuse intercapillary glomerulosclerosis, arteriolosclerosis, and tubular atrophy with marked tubular basement membrane thickening characteristic of advanced diabetic nephropathy. All three patients manifested uremia and resumed hemodialysis. Two patients died from sepsis within 2 months and one patient died 2.5 yr later after resumption of maintenance hemodialysis. We infer that recurrent or de novo diabetic nephropathy in renal allografts follows a clinical decade-long course irrespective of diabetes. Reports of ESRD due to allograft diabetic nephropathy (ADN) have been limited because of shorter survival of diabetic transplant recipients and few kidney biopsies performed in patients with chronic allograft dysfunction. The occurrence of allograft diabetic nephropathy in some, but not all patients, however, suggests that individual genetic variability modulates disease expression.

Among 432 patients receiving renal transplants (RT) between 1986 and 2002, 238 were Qatari nationals and 194, expatriates of mixed nationalities. Since 1986 when we started a local transplant program, 70 cases were performed at our center and 362 abroad. Diabetic nephropathy was the most common cause of end-stage renal disease among Qatar and chronic glomerulonephritis among expatriate patients. New-onset diabetes was reported after the transplant operation in 7.3% of the cases. Recipient age ranged from 14 to 75 years with the mean of 48.5 years among diabetics and 34.5 years among nondiabetics. Acute rejection occurred in 19.2% with chronic allograft nephropathy in 16.2% of cases. Two-year survival rates at our center versus the abroad units were 98% and 97% for patients and 85.7% and 82.5% for grafts respectively. The mortality was mainly related to myocardial infarction, which occurred significantly more often among diabetics. Other causes of mortality, such as sepsis, hepatic failure, and cytomegalovirus infection, did not differ significantly between diabetic and nondiabetic patients. The donor source at our center was living related (78.6%), cadaver (18.5%), and living unrelated (2.9%) as compared to 29.3%, 6.6%, and 64.1% of those performed abroad, respectively. The 5-year survivals among living-unrelated allografts performed abroad was 45.2% compared to 64.3% in living-related and cadaveric donors. Despite the disappointing results, the existing shortage of local kidney donors persuades our patients to go abroad for living- unrelated transplants. Educational programs and incentives are recommended to increase the supply of cadaver organs.

Eosinophilic peritonitis is defined as when there are more than 100 eosinophils present per milliliter of peritoneal effluent, of which eosinophils constitute more than 10% of its total WBC count. Most cases occur within the first 4 weeks of peritoneal catheter insertion and they usually have a benign and self-limited course. We report a patient of eosinophilic peritonitis that was successfully resolved without special treatment. An 84-year-old man with end stage renal disease secondary to diabetic nephropathy was admitted for dyspnea and poor oral intake. Allergic history was negative. and physical examination was unremarkable. Complete blood count showed a hemoglobin level of 11.1 g/dL, WBC count was 24,500/mm3 (neutrophil, 93%; lymphocyte, 5%; monocyte, 2%), platelet count was 216,000/mm3, serum BUN was 143 mg/dL, Cr was 5.7 mg/dL and albumin was 3.5 g/dL. Creatinine clearance was 5.4 mL/min. Three weeks after peritoneal catheter insertion, he was started on peritoneal dialysis with a 6-hour exchange of 2L 1.5% peritoneal dialysate. After nine days, he developed turbid peritoneal effluents with fever (38.4 degrees C), abdominal pain and tenderness. Dialysate WBC count was 180/mm3 (neutrophil, 20%; lymphocyte, 4%; eosinophil, 76% [eosinophil count: 136/mm3]). Cultures of peritoneal fluid showed no growth of aerobic or anaerobic bacteria, or of fungus. Continuous ambulatory peritoneal dialysis (CAPD) was commenced, and he was started on intraperitoneal ceftazidime (1.0 g/day) and cefazolin (1.0 g/day). After two weeksr, the dialysate had cleared up and clinical symptoms were improved. Dialysate WBC count decreased to 8/mm3 and eosinophils were not detected in peritoneal fluid. There was no recurrence of eosinophilic peritonitis on follow-up evaluation, but he died of sepsis and pneumonia fifteen weeks after admission.

In the present study, we evaluated the clinical course and outcome of chronic peritoneal dialysis (PD) in a group of elderly patients. We enrolled 60 elderly patients (37 men, 23 women) starting PD over a 4-year study period and assessed outcomes. The mean age of our patients was 61 +/- 7 years; mean PD duration was 16 months (range: 3 - 40 months). Primary diseases were mainly diabetic nephropathy (54%) and glomerulonephritis (20%). In most patients, the PD modality was chosen because of cardiac instability. Complications during PD included peritonitis (1 episode per 9 patient-months) and exit-site infection (1 episode per 26 patient-months). Technique survival was 89% at 1 year. Patient survival was 83% and 32% at 1 and 4 years respectively. The most frequent causes of death were cerebrovascular accident, cardiac complications, and sepsis. We also compared predialysis parameters to final parameters for 20 deceased patients. Mean age in this group was 62 +/- 8 years, and mean PD duration was 13 +/- 8 months. Body mass index (BMI) was 23 +/- 3 kg/m2 predialysis versus 22 +/- 3 kg/m2 at the end of dialysis (p < 0.01); residual renal creatinine clearance was 4.4 +/- 2 mL/min versus 2.3 +/- 2 mL/min (p < 0.003), and weekly total Kt/V was 2.1 +/- 0.3 versus 1.8 +/- 0.3 (p < 0.002). Albumin showed positive correlations with BMI (r = 0.40, p < 0.02) and with creatinine (r = 0.40, p < 0.01). We conclude that survival of elderly patients on continuous ambulatory peritoneal dialysis is reasonable in the first year, and that further improvement may be achieved by initiating dialysis early, by increasing the dialysis dose, and by improving the patients' nutrition status.

Foot lesions in postrenal transplant diabetics are often overlooked and hence underestimated. An audit of patients attending the authors' department was done. They reviewed the case notes to assess the presentation, clinical profiles, and outcomes of foot infections in patients with diabetes mellitus who received renal transplants at their center. Medical records of 192 diabetic foot patients were assessed, of which 8.8% (n = 17) had a history of previous renal transplantation for diabetic nephropathy. All 17 patients had noninsulin-dependent diabetes of mean duration of 16.2 years (range 7-27 years). Common complications and risk factors were studied. Mean duration to development of foot lesions in renal allograft recipients was 19.7 months (range 6-84 months). The big toe was the most common site of infection. Neuropathy and poor foot care appear to be important factors in the development of these foot lesions. Escherichia coli was the predominant organism on pus culture. Thirty-eight percent of patients needed major amputations; absence of an intact distal vascular tree was associated with a high major amputation rate. Two patients expired due to foot-related septicemia, and healing occurred in the remainder. Mean hospitalization time was 32.7 days. Most patients required more than one admission. The study emphasizes the need for greater attention to lower extremity complications in this patient group.

Between April 1995-December 2003, 1,324 deceased donor kidney transplantations were performed in 139 transplant institutes in Japan. Of these, 45 transplants were from heart-beating and 1,279 transplants were from non-heart-beating deceased donors (NHBDD). Clinical outcomes for the 1,279 recipients of NHBDD kidney transplants were investigated. The overall 5-year patient and graft survival rates were 90% and 72%, respectively. A total of 112 NHBDD kidney grafts never functioned after transplantation and the recipients had to remain on dialysis. The causes of nonfunction were rejection, primary nonfunction, death, thrombosis and others in the order of the incidence. The major causes of graft loss were nonfunction, death, chronic rejection and acute rejection in that order. Major causes of recipient deaths were pneumonia, sepsis and CVA within 12 months, and heart diseases, sepsis, malignancy and pneumonia more than 12 months after transplantation. Kidneys from female donors, donors aged 15 or less or over age 60, donors with extrinsic causes of death other than head trauma, recipients over age 60 and those with diabetic nephropathy as their original disease were found to be at risk for poor graft survival. The lowest and last donor serum creatinine level did not influence the incidence of nonfunction or graft survival. However, graft survival was significantly poorer among recipients of older "expanded" donor kidneys than for recipients of younger grafts. The warm and total ischemia times should be kept shorter than 30 minutes (better 15 minutes), and 12 hours, respectively to minimize the incidence of nonfunction and early graft loss. It is especially important in cases with WIT over 30 minutes that the total ischemia should be kept within 12 hours. Cannulation before cardiac standstill was important to reduce the incidence of nonfunction and achieve high graft survival rates with NHBDD kidneys. The discontinuance of ventilator support also reduced the incidence of graft nonfunction. The combination of CsA or Tacrolimus and MMF as both the induction and maintenance regimen significantly improved graft survival. The use of either anti-T cell antibodies or basiliximab was also associated with significantly better graft survival for NHBDD kidneys. The combination of basiliximab, CsA and MMF resulted in a graft survival rate of 98% at one and 2 years.

We analyzed survival rates of 144 prevalent patients on maintenance hemodialysis from 1998 to 2003 at the Department of Nephrology and Dialysis, Rijeka University Hospital, Rijeka, Croatia, and evaluated risk factors predicting their survival. Included were only end-stage renal disease (ESRD) patients on maintenance hemodialysis treatment dialysed more than 6 months before entering the study and who were clinically stable. The patients were randomised in two groups according to the presence or absence of diabetic nephropathy as the cause of ESRD and followed-up. The patient's death as outcome measure was recorded. The survival rates were estimated by the Kaplan-Meier method. The major causes of death were cardiovascular disease in 40 (60.6%) patients. An acute myocardial infarction in 15 (22.7%) patients was the major single cause of death. We found a significantly lower survival of diabetic patients than non-diabetic patients (P=0.0013). The most important predictors of death among diabetic patients on maintenance hemodialysis were hyperglycaemia (P<0.001), ischemic heart disease (P=0.004), hypercholesterolemia (P=0.013), and low delivered dialysis dose (P=0.013). The survival of diabetic patients undergoing hemodialysis was much worse than survival of non-diabetic patients. The cardiovascular disease remained the major cause of death in both groups. Early detection of pre-existing cardiovascular risk factors and diseases, and treatment of infections leading to sepsis, are of great importance, as they may influence the survival rates. Intensive management of diabetic patients is essential.

The aim of this study was to describe the clinical spectrum of chronic renal failure (CRF) in the elderly. The diagnosis of CRF was made using standard clinical criteria. The elderly was defined as person with over 60 years of age. In total, 200 elderly patients with CRF were evaluated between July 2002 and February 2004. Their age (male: 146; female: 54) ranged between 60 and 90 (mean 64.31+/-4.18) years. Diabetic nephropathy was the most common (46%) cause of CRF. Hypertensive nephrosclerosis, chronic interstitial nephritis and obstructive uropathy were responsible for CRF in 18%, 14% and 13% of patients, respectively. We observed chronic glomerulonephritis in 7% of elderly CRF. Urinary tract infection (55.5%), hypovolemia (22.2%), accelerated hypertension (11.1%) and sepsis (11.1%) were responsible for acute exacerbation of renal failure in 36 (18%) patients. Associated co-morbid conditions were noted in 93 (46.5%) patients. They included; coronary artery disease 46 (49.46%), cerebrovascular disease 20 (21.50%), osteoarthritis 13 (13.97%), chronic obstructive pulmonary disease 6 (6.45%), dilated cardiomyopathy 5 (5.37%), and malignancy in 3 (3.22%) patients. Acute dialytic support was required in 164 (82%) cases and remaining 36 (18%) patients received conservative management. Mortality was noted in 25 (12.5%) cases. The coronary artery disease (48%), acute pulmonary edema (20%) and hyperkalemia (12%) were the main causes of death. Subsequent evaluation revealed that 102 (51%) patients had ESRD of which only 3 (2.94%) patients could afford CAPD. A total of 11 (10.7%) patients underwent chronic maintenance hemodialysis for 3-4 months and then discontinue dialysis mainly because of financial constraints. Remaining 88 (86.27 %) patients with ESRD were discharged from hospital after symptomatic improvement with acute dialysis. Thus, diabetic nephropathy related to type-2 diabetes was the commonest cause of CRF in our elderly patients. Chronic renal failure in elderly was associated with a number of co-morbid conditions, which contributed significantly to morbidity and mortality. Acute on chronic renal failure with severe uremic complications were an important cause of hospitalization. The financial constraint was the major limiting factor for the management of elderly ESRD patients.

This prospective study was undertaken to study the spectrum of renal failure and the outcome in elderly patients. Patients included in the study group were elderly (age>60 years) who either attended outpatient renal clinic and or were hospitalized. Renal failure was classified as acute renal failure (ARF), rapidly progressive renal failure (RPRF) and chronic renal failure (CRF). A total of 4255 elderly patients were seen, of these 236 (5.5%) had renal failure. Mean age was 65.1+/-4.2 years (60-86 years). CRF was the commonest, seen in 137 (58.1%) followed by ARF 69 (29.2%) and RPRF in 30 (12.7%) patients. Diabetic nephropathy was the commonest cause of CRF, seen in 58.4% followed by chronic interstitial nephritis in 9.5% and chronic glomerulonephritis in 8.7% of patients. Of 137 patients 53 (38.7%) presented in end stage renal disease (ESRD). Of these 41 (77.3%) were initiated on maintenance hemodialysis and 12 (22.6%) on continuous ambulatory peritoneal dialysis. Only 15 patients were on dialytic support at the end of 1 year. Sepsis contributed to ARF in 75.4% of cases. Forty of 69 patients (57.9%) needed dialytic support. Forty (57.9%) were critically ill, defined as presence of two or more organ system failures (excluding renal failure). Forty two patients (60.9%) died patients. Acute interstitial nephritis (AIN) was the commonest cause of RPRF seen in 10 (33.3%) patients followed by vasculitis in 7 (23.3%). Myeloma cast nephropathy contributed towards RPRF in 20% of patients. Of 30 patients, 10 (33.3%) reached ESRD at end of 3 months of follow up, 4 (13.3%) died due to sepsis. Only 2 showed complete recovery while 14 (46.6%) had partial improvement. AIN patients had a relatively better outcome.
