We retrospectively investigated the incidence and prognosis of and risk factors for cerebrovascular events in 1,064 patients with chronic uremia who received maintenance hemodialysis (HD) for more than 3 months during 24 years in our dialysis units in Miyazaki, Japan. Cerebrovascular events developed in 98 patients (9.2%). The confirmed incidences of cerebral hemorrhage (CH) and infarction were 8.7 and 3.7 per 1,000 patient-years, respectively. Of the 56 patients with CH, 40 (71.4%) died within 3 months of the onset of CH. Ganglio-thalamic lesion was observed in 32 (80.0%) of 40 patients with CH confirmed by a brain computed tomography. The incidence of polycystic kidney disease was higher in the CH group than in the overall HD population (12.5% v 3.9%, P < 0.01). Of the 13 patients with diabetes mellitus and nephrosclerosis, nine (69.2%) developed CH within 36 months of the initiation of HD; 11 (78.6%) of 14 patients with chronic glomerulonephritis developed CH after 36 months. CH developed in six patients (15.0%) within 6 hours of a previous HD session. We compared laboratory values, the supine blood pressure, and electrocardiographic (ECG) findings in 35 patients with CH and a control group (66 patients) matched in age, sex, basal renal disease, age at the initiation of HD, and the duration of HD. Data were obtained before and after HD 3 to 4 months before the first attack of CH. The systolic and diastolic blood pressure (SBP, DBP) before and after HD were significantly higher in the CH group than in the control group (pre-HD SBP: 171 +/- 22.5 v 154 +/- 19.3 mm Hg, P < 0.001; pre-HD DBP: 89 +/- 13.6 v 81 +/- 9.6 mm Hg, P < 0.001). The incidence of left ventricular hypertrophy was higher, and the Kt/V was significantly lower (1.23 +/- 0.26 v 1.38 +/- 0.34, P < 0.05) in the CH group than in the control group. However, there were no significant differences in the serum levels of albumin and cholesterol or the total dose of heparin during HD sessions between groups. In conclusion, the incidence of CH was high, and its prognosis was poor, in patients undergoing maintenance HD. Reversible risk factors include hypertension and possibly the amount of HD prescribed, but not anticoagulation with heparin.

Family history of renal disease has been associated with an increased risk of end-stage renal disease (ESRD). It is uncertain whether this risk is mediated by familial aggregation of risk factors for ESRD, such as diabetes and hypertension. The association of ESRD with familial aggregation of renal disease was examined in a large, population-based case-control study conducted in Maryland, Virginia, West Virginia, and Washington, DC. The number of first-degree relatives who were affected with any type of renal disease was compared between 689 newly treated ESRD patients registered in the Medicare ESRD program (92% of all eligible incident cases presenting between January and July of 1991) and 361 control subjects without ESRD who were selected by random-digit dialing (90% response rate). Patients and control subjects were frequency matched by age; patients with ESRD caused by polycystic kidney disease and other known hereditary kidney diseases were excluded. Analysis was conducted using multiple logistic regression. After controlling for the proband's age, gender, race, family size, socioeconomic status, and personal and family histories of diabetes and hypertension, having one first-degree relative with renal disease increased the odds of ESRD by 1.3 (95% confidence interval, 0.7 to 2.6) and having two or more affected first-degree relatives increased the odds of ESRD by 10.4 (95% confidence interval, 2.7 to 40.2). These data support familial aggregation of renal disease in excess of that predicted by clustering of diabetes and hypertension within families, suggesting that either genetic susceptibility or environmental exposures shared within families increase the risk of developing ESRD. This risk is also much higher when two or more first-degree relatives have renal disease. Unraveling the molecular basis of this increase in risk may provide new avenues for treatment and prevention of ESRD.

We analyzed retrospectively the outcome of 169 patients in chronic hemodialysis (CHD), divided into four groups: 1) 24 patients with diabetic nephropathy (age 53.7 +/- 11 years); 2) 19 with polycystic kidney disease (age 55.3 +/- 9 years) 3) 43 patients older than 60 when starting chronic hemodialysis with etiologies different from diabetes and polycystic kidney disease (age 69.2 +/- 5.8 years) and 4) 83 patients younger than 60 with diverse etiologies (age 42.8 +/- 12.4 years). In groups 1, 2 and 3 serum creatinine, arterial hypertension at the beginning, morbility, mortality and its causes were registered. In group 1, the prevalence of severe diabetic retinopathy and cardiovascular disease at the beginning were also analyzed. In all groups survival was determined. Of the diabetics, 92% presented severe diabetic retinopathy and 88% cardiovascular disease. The prevalence of hypertension was 100, 74 and 67% in groups 1, 2 and 3, respectively (p = 0.13). Twelve diabetics died before the first year of treatment; there was no difference in creatinine, age, cardiovascular disease, severe retinopathy and hypertension with those who lived more than one year. The percentage of time in risk hospitalized and the days/patients/year hospitalized were significantly different between group 1 and 3 and group 2 (p < 0.001). Patients were hospitalized for similar causes in groups 1 and 3: the initiation of CHD, cardiovascular and neurological diseases. The main causes of death in groups 1 and 3 were: cardiovascular disease and sudden death at home. Survival was better in group 2 compared with group 1 (p = 0.0014) but was similar between groups 1 and 3 (p = 0.21) even though there was a difference of 15 years between them. The Cox's proportional hazard model identified as risk factors diabetes, age, year of starting chronic hemodialysis and hospitalization episodes, adjusted for covariates. The outcome of diabetic patients in chronic hemodialysis showed high morbidity and mortality and was quite similar to that of elderly patients.

Two patients with methicillin-resistant Staphylococcus aureus (MRSA) infection were treated with vancomycin (VCM)-impregnated polymethylmethacrylate (PMMA) beads. One patient, who had a history of polycystic kidney and diabetes mellitus, who was receiving hemodialysis due because of non-functional kidney, underwent resection of an intermediate grade chondrosarcoma in the pelvis. MRSA infection developed and curettage of the lesion was performed, but MRSA infection recurred. During the second revision surgery, VCM-impregnated PMMA beads were implanted. MRSA infection has not recurred for 16 months since the implantation of the VCM beads. The second patient had a history of total hip arthroplasty (THA) performed because of coxarthrosis. After the initial surgery, MRSA infection developed, recurring after the second revision surgery for THA. After curettage following removal of the prosthesis, VCM beads were implanted with a spacer composed of VCM-PMMA and a Luque rod. Infection did not recur and THA revision was performed 3 months after the VCM beads implantation. Fifteen months after the last revision surgery, infection has not recurred.

To identify Chinese geneticists' views of ethical issues in genetic testing and screening, a national survey was conducted. Of 402 Chinese geneticists asked to participate, 255 (63%) returned by mail anonymous questionnaires. The majority of respondents thought that genetic testing should be offered in the workplace for alpha-antitrypsin deficiency (95%) and the predisposition of executives to heart disease, cancer, and diabetes (94%); that genetic testing should be included in preemployment physical examinations (86%); that governments should require premarital carrier tests (86%), newborn screening for sickle cell (77%), and Duchenne muscular dystrophy (71%); and that children should be tested for genes for late-onset disorders such as Huntington disease (85%), susceptibility to cancers (85%), familial hypercholesterolemia (84%), alcoholism (69%), and Alzheimer disease (61%). Most believed that partners should know each other's genetic status before marriage (92%), that carriers of the same defective gene should not mate with each other (91%), and that women should have a prenatal diagnosis if medically indicated (91%). The majority said that in China decisions about family planning were shared by the couple (82%). More than half had views that, in China, there were no laws to prohibit disability discrimination (64%), particularly to protect people with adult polycystic kidney disease (57%), cystic fibrosis (56%), or genetic predisposition to other diseases (50%). To some extent, these results might provide a basis for a discussion of eugenics in China, particularly about China's Maternal and Infant Health Care Law (1994).

To explore the possibility that hereditary factors increase the risk for end-stage renal disease (ESRD), 669 patients with ESRD in the province of Newfoundland, Canada from 1987 to 1993 were studied. Detailed family histories were obtained from 584 (87%) consecutive probands and 499 spousal control subjects. Diseases with a Mendelian pattern of inheritance accounted for 8.4% of the cases; 4.5% of the cases were caused by autosomal dominant polycystic kidney disease (ADPKD). Glomerulonephritis was the original cause of renal failure in 25% of the probands, diabetes mellitus (DM) in 20%, unknown in 14%, interstitial kidney disease in 11%, other disease in 12%, multifactorial in 4%, and hypertension in 5%. In the group without a Mendelian pattern of inheritance, 28% of the probands had a first-, second-, or third-degree relative with renal failure associated with death or dialysis versus 15% of the controls. Compared with 0.4% of the control group, 1.2% of the first-degree relatives of probands developed renal failure (odds ratio [OR]=3.0; 95% confidence interval [CI], 1.7 to 5.2). No difference was observed when risks were compared for second-degree relatives, but a highly significant increased risk was observed for third-degree relatives (OR=2.1; 95% CI, 1.2 to 3.4). The highest rates of affected first-degree relatives occurred in probands with hypertensive renal failure (2.3%), DM (1.6%), and interstitial kidney disease (1.6%). The annual provincial incidence of ESRD, registered with the Canadian Organ Replacement Registry (CORR) from 1981 to 1993 was 79 per million, excluding the 8% of patients with Mendelian inherited disease. The similar rate of ESRD in first-degree relatives of probands without Mendelian inherited disease was 297 per million. We conclude that not only is the contribution of Mendelian inherited diseases to ESRD high, but there is also an increased risk for renal failure in first-degree relatives of probands without a Mendelian inherited renal disease in a white population.

Human lymphocyte antigen (HLA)-identical sibling organs offer the best long-term outcomes for recipients of a renal transplant apart from an identical twin. Unlike cadaveric transplants, however, factors that affect long-term survival of these immunologically privileged grafts are not well described. We reviewed 108 HLA-identical transplants performed at our institution between January 1977 and February 1993. Variables chosen for graft survival analysis were: gender, age and ABO blood type of donors and recipients, panel reactivity antibodies (PRA), blood transfusions prior to transplant, pregnancies, and the underlying renal disease. Additionally, incidence of acute rejection (AR), timing of AR, serum creatinine levels at 1 wk and at 1 yr, and presence of hypertension were included in the analysis. Mean follow-up was 130.9 +/- 58.2 months (range 38-250 months). Actual 5-yr patient and graft survivals were 92 and 88%, respectively. Thirty-eight grafts were lost, and 22 recipients died during the observation period. Death was the main cause of graft failure. Cardiac events accounted for the majority of deaths. AR occurred in 46% and repeated rejections in 11% of recipients. Actuarial graft survival at 10 yr was poorer for patients with any AR (69%), and significantly worse with repeated AR (33%), compared to patients without AR (86%), p = 0.001). Sixty percent of all rejections and 88% of the first rejections occurred in the first 60 d post-transplantation. The first AR that occurred after 60 d was associated with poor graft survival (49 vs. 70%, p = 0.04). Recipients with renal diseases with potential to recur (membranous glomerulonephritis (MGN), membrano-proliferative glomerulonephritis (MPGN), focal and segmental glomerulonephritis (FSGN), polyarteritis nodosa (PAN), rapid progressive glomerulonephritis (RPGN), Henoch-Schoenlein purpura (HSP), diabetes mellitus (DM), interstitial nephritis, systemic lupus erythematosus (SLE) and chronic glomerulonephritis (CGN)) faired worse as a group than recipients with hypertensive nephrosclerosis (HTN), autosomal dominant polycystic kidney disease (ADPKD), Alport's, reflux or congenital dysplasia (68 vs. 96% at 10 yr, p = 0.0009). Poor patient survival was seen in diabetics (71 vs. 88% at 10 yr, p = 0.01). There was a trend to poorer graft survival in diabetic recipients when compared to non-diabetics (65 vs. 81% at 10 yr, p = 0.054). Elevated creatinine at 1 yr was associated with worse graft survival. Likewise, the magnitude of creatinine increase during the first year directly correlated with the risk of graft loss. Hypertensive patients were more likely to lose their grafts than normotensive recipients (72 vs. 86%, p = 0.04). Pre-transplant blood transfusion, pregnancy, and PRA level were not associated with increased graft failure or AR. Graft survival was not affected by gender, age, or ABO blood type of donors or recipients. In conclusion, better prevention and treatment of AR, hypertension, and cardiac disease should improve graft and patient survival. Close attention to recurrence of disease and subtle changes in the creatinine level during the first year might dictate early diagnostic and, hopefully, therapeutic interventions.

Cardiovascular abnormalities have been considered important extrarenal manifestations of autosomal dominant polycystic kidney disease (ADPKD). However, little is known about their prevalence in patients with ADPKD undergoing hemodialysis (HD). To investigate whether cardiac abnormalities are more prevalent in these patients, clinical and echocardiographic manifestations of cardiovascular disease were evaluated in a group of 32 patients with ADPKD and a matched control group of 32 patients without diabetes treated by chronic HD for more than 6 months. Predialysis systolic and diastolic blood pressure (BP), prevalence of hypertension, and number of patients requiring antihypertensive medications were lower in the ADPKD group than controls. There was no difference in the prevalence of cardiac events, including cardiac failure, ischemic heart disease, and arrhythmia. Systolic dysfunction, diastolic patterns, and left ventricular hypertrophy were similar in the two groups. In patients with ADPKD, simple regression analysis showed left ventricular mass (LVM) index was correlated with hemoglobin level and predialytic systolic and diastolic BPs. In multiple regression analysis, predialysis systolic BP was the only independent variable linked to LVM index. The prevalence of aortic, mitral, and tricuspid valve disease did not differ between groups. In conclusion, the occurrence of cardiovascular complications in patients with ADPKD is similar to that of HD patients with other primary renal diseases, although hypertension is less prevalent.

One of the classic histologic forms of renal osteodystrophy is osteitis fibrosa, and its distinguishing characteristic is bone marrow (BM) fibrosis, caused by the activation of marrow parenchymal cells. A bone biopsy must be performed in order to establish the diagnosis of renal osteodystrophy. The clinical use of bone biopsy is restricted, however, due to the invasiveness of the procedure. In recent studies, bone scans have provided information useful for the differential diagnosis between osteomalacia and osteitis fibrosa. However, bone scans can not provide information on the bone marrow status. Bone marrow immunoscintigraphy (BMIS) using Tc-99m anti-granulocyte antibody (AGA), a highly sensitive test for the detection of bone marrow abnormalities which is also a noninvasive method, has rarely been reported in chronic renal failure (CRF). BMIS can provide information in patients with myelofibrosis. The purpose of this study was to evaluate the usefulness of BMIS in CRF patients with special regards to biochemical parameters. Nineteen CRF patients (13 men, 6 women; mean age: 48 +/- 11 years) in whom bone scintigraphy using Tc-99m MDP (methylene diphosphonate) showed the so-called superscan pattern were included in the study. Their primary renal diseases were chronic glomerulonephritis (n = 14), diabetes (n = 4), and polycystic kidney disease (n = 1). Modes of therapies were continuous ambulatory peritoneal dialysis (CAPD) (n = 13; mean duration: 9.5 months), HD (n = 5; mean duration: 7.8 months), and conservative treatment (n = 1). BMIS using Tc-99m labeled anti-granulocyte monoclonal mouse antibody BW250/183 was performed, and the results were compared with the biochemical parameters of the patients. According to the presence of BM expansion, which may represent marrow fibrosis, the 19 patients were divided into two groups: Group I (n = 7) with BM expansion and Group II (n = 12) with normal marrow distribution. The biochemical parameters and bone markers of Group I were compared with those of Group II. There was no significant difference in biochemical parameters (blood hemoglobin, serum ferritin, erythropoietin, BUN, creatinine) between the two groups. There were no significants difference in serum calcium, phosphorus, tartate-resistant acid phosphatase (TRAP), and intact parathyroid hormone (iPTH) between the two groups. Serum alkaline phosphatase (ALP) and osteocalcin were significantly (P < 0.05) higher in Group I than in Group II. These results suggest that patients with bone marrow expansion in BMIS have increased levels of ALP and osteocalcin, indicating an increased osteoblastic activity. BMIS may be useful for the detection of bone marrow expansion due to marrow fibrosis in renal osteodystrophy, and for the evaluation of the extent of bone marrow fibrosis.

The purpose of our study was to compare the incidence of peritonitis between continuous ambulatory peritoneal dialysis (CAPD) treatment (Group I) and automated peritoneal dialysis (APD) treatment (Group II) taking into account the same population. We compared 20 patients with a follow-up of 215 patient-months on CAPD and 252 patient-months on APD. Demographic data, diagnosis, peritoneal equilibration test (PET) results, adequacy, and peritonitis rate were analyzed. Diagnoses included glomerulopathy 35%, autosomal dominant polycystic kidney disease (ADPKD) 20%, Type II diabetes 10%, systemic lupus erythematosus 5%, interstitial nephritis 5%, nephrolitiasis 5%, and unknown 20%. PET results showed that the group consisted of 30% high transporters, 45% high-average transporters, and 25% low-average transporters. Kt/V for Group I was 1.3 +/- 0.3, and for Group II, 1.83 +/- 0.48. Creatinine clearance for Group I was 43.64 +/- 7.31 L/week/1.73 m2, and for Group II, 52.42 +/- 13.47 L/week/1.73 m2. Group I presented a peritonitis rate of 8.3 episodes/patient-month, and Group II presented a rate of 18.9 episodes/patient-month. Gram-positive organisms were responsible for 49.8% of episodes of peritonitis in Group I (S. aureus 26.6%, S. epidermidis 16.6%, others 10%) and 83% of peritonitis episodes in Group II (S. epidermidis 46.6%, S. aureus 20%). Gram-negative organisms were responsible for 16.5% of episodes of peritonitis in Group I. No gram-negative peritonitis was seen in Group II. APD patients developed two cases of candida peritonitis. Our preliminary results show that Group II exhibited a decrease in peritonitis rate while achieving better adequacy. In CAPD and APD peritonitis, gram-positive organisms predominated. In APD, we observed an increase in S. epidermidis incidence. No gram-negative organisms were observed in APD. It seems that APD is a safer treatment owing to the lower peritonitis incidence.
