Abstract
Chronic viral hepatitis remains a major problem among patients with chronic renal failure. Hepatitis B and C viruses are frequent among dialysis patients and after renal transplantation and may significantly diminish the survival of both the patient and the graft. Hepatitis B and C viral infection in these patients is often characterized by normal transaminase levels despite viremia and progressive liver lesions. Liver biopsy remains essential for assessing the extent of liver disease. Cirrhosis is a contraindication to transplantation of only a kidney, because of elevated morbidity and mortality. A combined as liver-kidney transplantation may be considered. The best treatment of hepatitis infections is preventive: vaccination against the hepatitis B virus and attentive hygiene, especially to prevent nosocomial transmission. Among patients not awaiting transplant, antiviral treatment should be reserved for patients with active or even fibrotic liver disease. For hemodialysis patients awaiting kidney transplant: Alpha interferon is ineffective and poorly tolerated by dialysis patients. Lamivudine is effective and well tolerated, but its long-term efficacy and its optimal effective dose in dialysis patients remain unknown.

Abstract
Treatment of chronic hepatitis B in renal transplant recipients remains one of the major problems in clinical nephrology. Lamivudine is considered to be a drug of choice for these patients, however, its efficacy in patients with hepatitis B after renal transplantation (RT) has not been completely proven. Twenty-two RT recipients treated with lamivudine were evaluated. The duration of treatment was 15.6+/-1.9 months. Fourteen patients (64%) had normalization of aminotransferase (ALT); in 9 of them (41% of the whole group), serum HBV DNA was eliminated. Serum HBeAg was undetectable in 4 out of 15 (27%) previously positive patients. It has been statistically proven that the efficacy of lamivudine therapy correlates with degree of fibrosis and higher histological activity index values. We could not establish any correlation between the outcome of antiviral therapy and patients' age, sex, conditions of contagion (while on dialysis or after RT), time lapsed after the infection had been detected, duration of post-transplant period, type of immunosuppression, HBeAg positivity or negativity, ALT levels, concomitant HCV infection. The efficacy of antiviral HBV therapy is limited by the duration of lamivudine treatment: in 4 out of 5 patients with virologic response, the viremia condition relapsed several weeks after the medication had been stopped. Two patients continued to sustain their biochemical response and 1 patient had ALT levels elevated to above normal, but the value was almost twice as low as initially reported. Liver biopsy was repeated in 4 RT recipients after the end of antiviral therapy; in 3 of them positive morphologic changes were observed.

Abstract
BACKGROUND Hepatitis B (HBV) historically has been a public health issue within hemodialysis units. This study estimates HBV prevalence and seroconversion rates across seven countries and investigates associations with facility level practice patterns. METHODS The study sample was from the Dialysis Outcomes and Practice Patterns Study (DOPPS), a cross-sectional, prospective, observational study of adult hemodialysis patients randomly selected from 308 dialysis facilities in France, Germany, Italy, Spain, the United Kingdom, Japan, and the United States. Logistic regression was used to model the odds ratio (OR) of HBV prevalence, and Cox regression was used to model time from entry into the study to HBV seroconversion. RESULTS In this sample, mean HBV facility prevalence was 3.0% with a median of 1.9%. The percentage of facilities with an HBV prevalence 0% to 5% was 78.5%. Adjusted HBV prevalence was higher in France, Germany, and Italy and lower in Japan and the United Kingdom. The majority of facilities (78.1%) had a seroconversion rate of 0 conversions per 100 patient-years. Presence of a protocol for HBV-infected patients was significantly associated with HBV seroconversion in the separate practice pattern model [risk ratio (RR) = 0.52, P = 0.03] and in the combined practice pattern model (RR = 0.44, P = 0.01). CONCLUSION There are differences in HBV prevalence and rate of seroconversion both at the country and the hemodialysis facility level. Presence of a protocol for HBV-infected patients was strongly and significantly associated with decreased risk for seroconversion. The observed variation suggests opportunities for improved HBV outcomes with further definition of optimal practice patterns at the facility level.

Abstract
BACKGROUND Studies have shown that protein-energy malnutrition (PEM) is a strong predictor of total mortality among patients with end-stage renal disease (ESRD). The aim of this study is to assess the relationship between nutritional indices and cardiovascular (CV) mortality among patients with ESRD by using data from the US Renal Data System (USRDS) Dialysis Morbidity and Mortality Study Wave I (DMMS-1). METHODS Demographic and medical data were abstracted from 5,058 patients who participated in the USRDS DMMS-1. Nutritional measurements of interest included subjective assessment of malnutrition, serum albumin level, body mass index (BMI), and cholesterol level. The USRDS provided follow-up data on mortality through July 1998. The Cox proportional hazard model was used to estimate the risk for CV death associated with nutritional markers. RESULTS The risk for CV death was 39% greater for each 1-g/dL (10-g/L) decrement in serum albumin level (95% confidence interval [CI], 1.20 to 1.60; P < 0.001). A care provider's assessment of malnutrition was associated with a 27% greater risk for CV mortality (95% CI, 1.08 to 1.50; P < 0.004). For each one-unit decrement in BMI, the risk for CV disease (CVD) was 6% greater (95% CI, 1.00 to 1.13; P < 0.046). Among patients without CVD at the study start, serum albumin level remained a significant risk factor for CV death (adjusted relative risk = 1.39 per 1-g/dL (10-g/L) increment; P = 0.026). In addition, change in albumin levels over time was significantly associated with CV mortality. For each 0.1-g/dL (1-g/L) decrement in albumin level per month, the risk for CV death was 2.24-fold greater (95% CI, 1.65 to 3.02; P < 0.001) among the entire cohort and 3.86-fold greater (95% CI, 1.96 to 7.60; P < 0.010) among those without a known history of CVD at the study start. CONCLUSION Both PEM at baseline and worsening PEM over time are associated with a greater risk for CV death. This finding persists among dialysis patients without preexisting CVD at baseline.

Abstract
BACKGROUND Hepatitis C is frequent problem in dialysis wards. DESIGN A long time (1989-97) follow up of hepatitis C virus (HCV) infection in a Swedish nephrology unit was performed with anti-HCV screening, confirmatory antibody tests, viral RNA detection and molecular characterization. Case histories were reviewed with focus, onset of infection, liver morbidity and mortality. RESULTS In October 1991, 10% (19 of 184) of the patients in the unit (haemodialysis-, peritoneal dialysis and transplanted patients) were verified or suspected HCV carriers, whilst the number at the end of 1996 was 8%, (13 of 157). Most patients were infected before 1991 but only in one case from a known HCV-infected blood donor. No new HCV infections associated with haemodialysis occurred during the study period. A total of 13 of 24 viremic patients had HCV genotype 2b, a pattern suggesting nosocomial transmission. This was further supported by phylogenetic analysis of HCV viral isolates in seven. HCV viremia was also common in patients with an incomplete anti-HCV antibody pattern as 8 of the 12 indeterminant sera were HCV-RNA positive. CONCLUSIONS Awareness, prevention, identification of infected patients and donor testing limited transmission. Indeterminant recombinant immunoblot assays (RIBA)-results should be regarded with caution as a result of the relative immunodeficiency in uremic patients. Our data indicate nosocomial transmission in several patients.

Abstract
BACKGROUND In end-stage renal disease patients with hepatitis B surface antigen (HBsAg), the risk of hepatic dysfunction after immunosuppression represents a large barrier in renal transplantation. Lamivudine is a potent inhibitor of hepatitis B virus (HBV) replication. We retrospectively investigated the outcome of HBsAg-positive renal transplantation recipients after lamivudine had become available. METHODS From July 1994 to August 2000, seventeen HBsAg-positive patients (M:F=15:2) received renal allografts (13:4=living:cadaveric donors). Liver function tests at the time of transplantation were normal in all patients. Pre-transplant liver biopsies performed in 15 patients demonstrated minimal inflammatory histology, except in three patients showing pathological and clinical signs of active hepatitis. Lamivudine was started pre-operatively in these three subjects. Another seven patients were treated with lamivudine for post-operative hepatic dysfunction. The remaining seven patients did not develop hepatic dysfunction after transplantation. RESULTS Lamivudine was initially effective in decreasing serum HBV DNA titres, and in normalizing hepatic enzymes. Lamivudine was well tolerated without significant side effects for 35.5+/-8.9 months after initiation of treatment. HBV DNA became negative in nine patients but remained positive in one patient. Among the nine patients with initial negative conversion of HBV DNA, two developed transient positive conversion of HBV DNA and two demonstrated persistent positive conversion. Among the patients with normal liver histology in the pre-transplant period, 41.6% (5/12) developed liver pathology progression after immunosuppression. All 17 patients had functioning grafts, except for one patient who developed relapsed IgA nephropathy. CONCLUSIONS Our data showed relatively favourable outcomes in hepatitis B-positive renal transplant recipients receiving lamivudine treatment, even though two patients developed lamivudine resistance.

Abstract
Many complications after renal transplantation can be prevented if they are detected early. Guidelines have been developed for the prevention of diseases in the general population, but there are no comprehensive guidelines for the prevention of diseases and complications after renal transplantation. Therefore, the Clinical Practice Guidelines Committee of the American Society of Transplantation developed these guidelines to help physicians and other health care workers provide optimal care for renal transplant recipients. The guidelines are also intended to indirectly help patients receive the access to care that they need to ensure long-term allograft survival, by attempting to systematically define what that care encompasses. The guidelines are applicable to all adult and pediatric renal transplant recipients, and they cover the outpatient screening for and prevention of diseases and complications that commonly occur after renal transplantation. They do not cover the diagnosis and treatment of diseases and complications after they become manifest, and they do not cover the pretransplant evaluation of renal transplant candidates. The guidelines are comprehensive, but they do not pretend to cover every aspect of care. As much as possible, the guidelines are evidence-based, and each recommendation has been given a subjective grade to indicate the strength of evidence that supports the recommendation. It is hoped that these guidelines will provide a framework for additional discussion and research that will improve the care of renal transplant recipients.

Abstract
BACKGROUND The impact of infection with hepatotropic viruses (hepatitis B virus [HBV] and hepatitis C virus [HCV]) on morbidity and mortality, and allograft function in renal transplant recipients with allografts functioning for >20 years is not known. METHODS AND RESULTS Seventy-nine of 511 renal transplants performed at the Cleveland Clinic Foundation from January 1963 to January 1978 are known to have functioned for at least 20 years (level 5A). Fifty-four of these patients had hepatitis testing updated after their 19th year of transplantation. Fifteen patients had evidence of ongoing viral infection: persistent hepatitis B surface antigen in three (6%), HCV antibody (enzyme-linked immunosorbent assay II supplemented by recombinant immunoblot assay) in 11 (20%), and both viruses in one (2%). Of the 10 surviving patients, 8 were tested further for viral replication. HCV RNA (polymerase chain reaction; Amplicore) was positive in 6/7 (86%), and HBV DNA (hybridization) was positive in 1/2 (50%). An elevated alanine aminotransferase (>35 U/L) was present in all hepatitis patients, alpha-fetoprotein >10 ng/ml in 2/8 (25%), and cryoglobulins >50 microg/ml in 3/6 (50%) infected with HCV. No hepatocellular carcinoma was detected by hepatic ultrasound. In patients with chronic viral hepatitis, probable cirrhosis developed in 20% (3/15) compared to one patient in the group without hepatitis, but there was no mortality from liver failure in either group. Diabetes mellitus was significantly more common in those with than without hepatitis (11/15 vs. 10/39; P=0.002), but severe infection was not (9/15 vs. 15/39). Five hepatitis patients (33%) have died of non-hepatic causes (one from meningitis, one from unknown cause, and three from coronary heart disease [CHD] vs. only two individuals without hepatitis [5%]; P= 0.014). Although the more frequent occurrence of CHD among those with hepatitis was not significant (7/15 vs. 8/39; P=0.09), CHD as a cause of death in those with HCV was significantly increased (P=0.03). CONCLUSIONS Twenty-year renal transplant recipients infected with hepatotropic viruses (HBV and HCV) have a high rate of active viral replication (88%), a greater frequency of diabetes (P=0.01), and a higher overall mortality (P=0.014).

Abstract
The impact of hepatitis B (HBV) and C (HCV) on patient survival after kidney transplantation is controversial. The aims of this study were (1) to assess the independent prognostic values of HBsAg and anti-HCV in a large renal transplant population, (2) to compare infected patients with noninfected patients matched for factors possibly associated with graft and patient survival, and (3) to assess the prognostic value of biopsy-proven cirrhosis. Eight hundred thirty-four transplanted patients were included: 128 with positive HBsAg (group I), 216 with positive anti-HCV (group II), and 490 without serological markers of HBV and HCV (group III). Fifteen percent and 29% of patients were HBsAg-positive and anti-HCV-positive, respectively. Ten-year survivals of group I (55 +/- 6%) and group II (65 +/- 5%) were significantly lower than survival of group III (80 +/- 3%, P <.001). At 10 years, among overall patients with HCV screening (n = 834), four variables had independent prognostic values in patient survival: age at transplantation (P <.0001), year of transplantation (P =.02), biopsy-proven cirrhosis (P =.03), and presence of HCV antibodies (P =.02). In the case control study, comparison of infected patients with their matched control patients showed that age at transplantation (P <.05), HBsAg (P =.005), and anti-HCV (P =.005) were independent prognostic factors. HCV, biopsy-proven cirrhosis, and age are independent prognostic factors of 10-year survival in patients with kidney grafts. The case-control study showed that anti-HCV and HBsAg were independently associated with patient and graft survivals. In infected patients, a routine liver histological analysis would improve selection of patients for renal transplantation.

Abstract
Hepatitis B and hepatitis C are two common pathogens causing chronic hepatitis in patients with end-stage renal disease (ESRD). With the acceptance of hepatitis B s antigen (HBsAg) screening, infected patients have been identified and isolated over the past 20 years. Consequently, hepatitis B is now being seen less frequently in dialysis units. Even though hepatitis B has become less of a problem, non-A, non-B hepatitis has been recognized as a significant problem since 1979. With the availability of serological testing for hepatitis C virus (HCV), more specific information is now available in regard to HCV infection in dialysis patients. The prevalence of anti-HCV in haemodialysis (HD) patients is quite variable, ranging from 5 to over 50%. Anti-HCV positivity is associated with previous blood transfusions, mode of therapy and duration of haemodialysis. In Spain and Italy, the annual seroconversion rates of HCV antibodies in dialysis patients are 2-9%; this rate was much higher in Taiwan (15%). Whether patients with HCV infection should be identified and isolated during HD treatment is an issue of controversy. Transplantation is associated with increases in hepatitis B virus (HBV) replicative markers. The survival disadvantage in HBsAg-positive recipients usually did not become apparent until 8 years after transplantation. Hepatitis C virus-infected renal transplant recipients are presumably in a similar situation to patients with hepatitis B, although confirmatory data are currently lacking. Coinfection of HBV and HCV may lead to aggressive liver disease and cirrhosis. A hepatitis B vaccine is recommended for all susceptible dialysis patients. Dialysis patients have lower response rates to hepatitis B vaccines than do other people. Currently, no vaccine is available for hepatitis C. To date, there are no effective treatments available for hepatitis B and hepatitis C. Combination therapy with interferon/lamivudine for hepatitis B and interferon/ribavirin for hepatitis C may offer a promise of effective control of viral replication in the future.

Abstract
At present, routine screening for hepatitis C virus (HCV) infection is based on the detection of antiviral antibodies. Underdiagnosis of HCV infection by using HCV antibody tests, however, still occurs. Additional diagnostic means are provided by the polymerase chain reaction (PCR). The measurement of aminotransferase (ASAT and ALAT) has served as an auxiliary, less specific test. The present research aimed to design practical and low cost strategies to diminish underdiagnosis of HCV infection in dialysis patients. With this purpose in mind, we examined whether aminotransferases values in HCV antibody-negative patients could be related to undiagnosed HCV infection, by using HCV RNA testing by PCR as the gold standard. In 112 hemodialysis patients, we found 78 negative and 34 positive for HCV antibodies. A major finding was that 222 (28.2%) out of the 78 HCV antibodies-negative patients had positive HCV RNA by PCR. In repeated samples taken at six months follow-up from 19 out of these 22 patients, only one of them was positive for anti-HCV antibodies; moreover, a positive HCV RNA by PCR was confirmed in 13 (68.5%) of them. Within the HCV antibody-negative group, the mean values of ASAT, ALAT and gammaglutamiltransferase were higher (P < 0.001, P < 0.001 and P < 0.02, respectively) in the HCV PCR-positive versus the HCV PCR-negative patients. No significant differences were found in the liver enzyme values between the HCV antibody-negative, HCV RNA positive and the HCV antibody positive, HCV RNA positive individuals. Histological samples from two HCV RNA positive, HCV antibody-negative patients disclosed the presence of a mild liver disease. In conclusion, the present study demonstrates the critical importance of HCV RNA determination by PCR in hemodialysis patients who have no detectable circulating antibodies against the HCV. Furthermore, in conditions in which PCR technology is not readily available, we have established that the existence of a moderate increase of aminotransferases is a helpful clue to detect patients with absent HCV antibodies, and might represent an useful, low cost tool for HCV screening in dialysis patients.

Abstract
Patients with chronic hepatitis run the risk of developing progressive liver disease during immunosuppressive therapy after kidney transplantation. To determine the impact of chronic hepatitis C on morbidity and mortality we analyzed 162 anti-HCV positive of 1241 renal-grafted patients (prevalence 13.1%; 84.9% HCV RNA positive) regularly surveyed in our outpatient clinic between 1992 and 1994. The mean age at transplantation was 44.5 (6-69) years, and follow-up after grafting was 7.4 (0.1-23.9) years. The immunosuppressive regimen and frequency of rejection episodes in HCV-infected patients were comparable to the total population. Only 4.3% (5/117) of the anti-HCV positive, HBV negative patients living with functioning grafts developed a markedly compromised liver function. Fifteen (9.3%) of the HCV-infected patients died, but none suffered from posthepatitic cirrhosis. An additional retrospective analysis of causes of death after transplantation prior to 1992 revealed that liver disease had only been responsible for 2% of the deaths (7 of 324) in the HBsAg negative population (n= 1901). In contrast, the predominant cause of death in the HBsAg positive population (n=76) was posthepatitic cirrhosis in 58% (15 of 26). Thus, kidney transplantation in patients with replicative hepatitis C and normal liver function appears to be justified because of low early and late morbidity and mortality due to chronic liver disease. HBV infection and hemosiderosis substantially increase the risk of chronic liver disease in renal transplant recipients with hepatitis C.

Abstract
Effective control measures to reduce the spread of HBV in dialysis units have had a major beneficial impact on the management of patients with chronic renal failure (Table 3). The exact impact of chronic HBV infection on graft and patient survival following RT remains unclear, and the outcome may depend in great part on the severity of the pre-RT liver disease. RT should only be offered to HBV-infected patients after careful consideration of all the pertinent data, including results of liver biopsy. Advances in HBV vaccination may further decrease the risk of infection in patients on HD. Our understanding of HCV is evolving rapidly, but the question of the risk of transmission of HCV within dialysis units is still unsettled and thus recommendations about isolation of HCV-infected patients are not possible. Although RT does not appear to be deleterious in many HCV-infected patients, histologic and clinical evidence of severe liver disease should also prompt caution in offering RT. Longer term studies are required to assess the ultimate effect of RT in patients with HCV. Clearly, subjective improvement of quality of life associated with successful RT compared to chronic dialysis should not be withheld lightly. Pending further experience, use of organs from anti-HCV-positive donors in non-emergent situations is best avoided. The role of antiviral agents in RT recipients with chronic viral hepatitis also remains to be defined. Improved supportive care of patients with chronic renal disease, including erythropoietin therapy, as well as improved tests for anti-HCV screening of donor blood will help to further diminish exposure to HCV in HD units.

Abstract
The last 4 years have been a period of rapid expansion in our understanding of both the molecular biology and clinical significance of hepatitis C virus (HCV) infection. Initial studies using first-generation enzyme-linked immunosorbent assays suggested that the end-stage renal disease population had an exceptionally high prevalence of anti-HCV compared with asymptomatic healthy blood donors. Subsequent analyses with second-generation assays and polymerase chain reaction techniques to detect viremia confirmed these earlier studies. Considering the prevalence of HCV within the dialysis population, it comes as no surprise that several studies confirmed HCV as the leading cause of non-A, non-B hepatitis among renal allograft recipients. Furthermore, transmission of HCV by transplantation of a kidney from an HCV-infected organ donor has been unequivocally demonstrated. The natural history of HCV infection in the immunosuppressed allograft recipient and its impact on long-term patient outcome are still being analyzed. Finally, HCV has been associated with essential mixed cryoglobulinemia and several histologic patterns of immune complex glomerulonephritis, including membranous and membrano-proliferative glomerulonephritis. Although HCV antigen-antibody complexes have not been demonstrated in the kidney, the marked decrease in proteinuria following clearance of HCV RNA with interferon alpha-2b therapy suggests an etiologic role for HCV in these glomerular diseases. Furthermore, the demonstration of HCV RNA in the cryoprecipitate of patients with essential mixed cryoglobulinemia and a beneficial response to treatment with interferon alpha-2b also suggest a role for HCV in the pathogenesis of these clinical syndromes.

Abstract
Interferon-alpha has not been used previously in hemodialysis patients with chronic hepatitis B and C. This uncontrolled report evaluates the biochemical and/or histologic profile resulting from the administration of interferon-alpha in seven hemodialysis patients, two with chronic hepatitis B and five with hepatitis C. Biochemical improvement was noted in all patients. Histologic progression did not occur in the two cases in which such assessment was made, and five of them were subsequently transplanted without recurrence of disease.

Abstract
Chronic hepatitis B surface antigen (HBsAg) carriers run a high risk of developing chronic liver disease after renal transplantation. To determine the impact of liver disease on long-term morbidity and mortality of HBsAg carriers following kidney transplantation we analyzed 1977 patients, including 76 HBsAg carriers, who underwent renal transplantation during the period 1968-1992. Although the HBsAg carriers had a better 5-year patient and graft survival rate (94% and 83%) than HBsAg-negative patients (87% and 61%), the prognosis was poor after the tenth year of transplantation. Transplant loss is more frequently caused by death of the HBsAg carriers, in contrast to the total population (34% vs 17% for HBsAg-negative patients). Death occurs in 73% of cases due to complications of hepatitis B. In the HBsAg-negative patients, the predominant cause of death is cardiovascular failure (51% vs 11% in HBsAg carriers), whereas only 2% died of liver disease. Kidney transplantation in HBsAg carriers with normal liver function appears to be justified because of rare graft loss due to acute rejection, low early morbidity and mortality, and late onset of fatal hepatic deterioration.

Abstract
The hepatitis C virus (HCV) may be an important cause of chronic liver disease in renal transplant recipients. We investigated retrospectively the incidence and outcome of HCV infection in long-term renal transplant recipients and patients on hemodialysis. Stored, pretransplant sera of transplant recipients with normal liver biochemistry at surgery were tested for hepatitis C by a second-generation enzyme immunoassay. Hemodialysis patients were tested by a first-generation enzyme-linked immunosorbent assay (ELISA) against c100-3. We studied 252 renal transplant recipients and 58 hemodialysis patients followed for 65 +/- 10 months and 26 +/- 6 months, respectively. Fifteen percent (38/252) of the transplant recipients were HCV positive as were 3/58 (5%) of the hemodialysis patients. Overt liver disease occurred in 22/252 (8.7%) transplant recipients and none in the hemodialysis group. Thirty-six percent (8/22) of transplant recipients with overt liver disease were HCV positive. No HCV-positive patients died of liver failure. Of six biopsies in the HCV-positive transplant group, two had histological evidence of CAH. CAH was seen in six of eight biopsies in the HCV-negative transplants and two of these latter patients progressed to cirrhosis. No hemodialysis patients had clinical or histological evidence of chronic liver disease. Two HCV-negative transplant patients died of liver failure, while no deaths related to liver disease occurred in hemodialysis patients regardless of HCV status. We conclude that hepatitis C may cause chronic hepatitis in renal transplant patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
HBsAg-positive patients with end-stage renal failure have a high prevalence of asymptomatic chronic hepatitis. In order to determine the usefulness of hepatic cytology in the diagnosis of liver disease, the findings of hepatic needle core biopsy (NCB) and fine needle aspirative biopsy (FNAB) were compared in 15 HBsAg-positive uremic patients. The patients, aged 42 +/- 12 years, 14 males, were on hemodialysis for periods ranging from 13 to 105 months. The NCB was processed by standard histologic and immunohistochemical techniques and FNAB by the conventional technique, using the total corrected increment score (TCI). Plasma samples were collected for evaluation of hepatic function and for viral serologic tests. In 15 patients a diagnosis was made by NCB: normal, 7 cases; chronic persistent hepatitis, 4 cases; and chronic active hepatitis, 4 cases. When the patients were allocated into two groups according to the severity of the liver histologic findings [group I--minor changes (normal+chronic persistent hepatitis), 11 patients; group II--major changes (chronic active hepatitis), 4 patients], statistically higher values were found in the major changes group for alanine aminotransferase (49 +/- 33 vs. 24 +/- 11, p = 0.04), gamma-glutamyl transpeptidase [148 +/- 53 vs. 38 +/- 28, p < (minor) 0.02] and TCI (3.7 +/- 1.2 vs. 2.5 +/- 0.8, p = 0.04). In conclusion, liver FNAB can be useful as a screening procedure for the identification of liver histologic changes (minor or major) in uremic HBsAG-positive patients.

Abstract
The present study correlated histopathology and diagnostic tests in hemodialysis patients with serologic markers for hepatitis C virus (HCV). Hepatitis C virus infection was found in 65 of 163 patients, as assessed by anti-c100-3 (ELISA 1), anti-c22-3, c33C (ELISA 2), and RIBA 2. Several histopathologic patterns were found in 33 liver samples from HCV-positive individuals: cirrhosis (n = 3), chronic active hepatitis (n = 14), chronic persistent hepatitis (n = 2), isolated hemosiderosis (n = 5), reactive hepatitis (n = 6), and others (n = 3). There was a positive correlation between time from the first aminotransferase peak and histologic damage (P = 0.015). However, the severity of liver disease did not correlate with the intensity of RIBA 2 positivity, mean levels or pattern of aminotransferases elevation, or markers of past hepatitis B virus infection. Moreover, aminotransferases were persistently normal in three patients with severe liver disease and were elevated in 10 patients with only mild changes. In 19 biopsied patients, the presence of plasma HCV RNA was examined by the polymerase chain reaction (PCR), which was positive in 15 of the 19 biopsy specimens. The ability of PCR positivity to predict the histologic severity of the disease was insufficient: four patients with minor liver damage had positive PCR and two patients with significant liver damage had negative PCR. No further correlations of PCR positivity were found with the other biochemical or immunologic markers of HCV infection.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The clinical and epidemiological relevance of circulating antibodies to hepatitis C virus (HCV) in hemodialysis patients is uncertain, since clinical signs of infection are often mild or absent, with alanine aminotransferase (ALT) values that are virtually always normal, and liver biopsies are only rarely performed. Determination of HCV RNA in serum is therefore critical for distinguishing chronic HCV infection from previous exposure to the virus. We studied HCV viremia by reverse transcription polymerase chain reaction (RT-PCR) in the 5'-noncoding region of the viral genome in 77 dialysis patients who were screened for anti-HCV by a second-generation enzyme-linked immunosorbent assay (the enzyme immunoassay II; Ortho HCV, 2nd generation, Ortho Diagnostic Systems Raritan, N.J.) and a second-generation recombinant immunoblot assay (Chiron Corporation and Ortho Diagnostic Systems) and prospectively evaluated for ALT elevations over a period of 5 years. Of 77 patients tested, 29 (38%) had active infection as shown by a positive PCR assay result, and of these, 26 were anti-HCV positive. Although a good correlation was found between circulating anti-HCV and HCV RNA in serum, 10 (28%) of 36 anti-HCV-positive patients were HCV RNA negative by PCR, suggesting either low levels of viremia or past exposure to HCV and subsequent recovery. On the other hand, 3 (7.3%) of 41 anti-HCV-negative patients had HCV RNA in their sera, indicating seronegative HCV infection. The ALT level had no predictive value for HCV infection, because it was repeatedly normal in 18 (62%) of 29 viremic patients. HCV genotyping was also performed and indicated that all four known genotypes of HCV were present in our group. In conclusion, serological assays are reliable for detecting exposure to HCV in hemodialysis patients; however, direct identification of the viral genome is required to document current infection.

Abstract
PURPOSE Liver disease is a frequent complication in renal transplant recipients. To understand the nature and progression of hepatic disease in these patients, we performed percutaneous biopsies in 77 subjects who had chronic liver dysfunction in the posttransplant period. The purpose of the present investigation is to delineate the morphologic spectrum of chronic liver disease in the renal allograft recipients and to characterize the clinical and histologic progression of each of the different morphologic forms. PATIENTS AND METHODS Between 1971 and 1990, 915 patients received renal transplants at the Hennepin County Medical Center, Minneapolis, Minnesota. One hundred nineteen (13%) of them had abnormal liver function that persisted for longer than 6 months. Percutaneous liver biopsies were performed in 77 of these patients, but adequate tissue for histologic evaluation was available in only 72. After the biopsy, the clinical and histologic course of each subject was monitored in relation to the baseline hepatic morphology. To assess the predictive value of serum enzymes in diagnosing the histologic lesions, the level of serum enzymes at the time of the biopsy was correlated with the morphologic diagnosis. In addition, several clinical, biochemical, etiologic, and histologic variables were screened for their association with histologic progression to liver cirrhosis. RESULTS The morphologic diagnosis in the 72 specimens evaluated at baseline was as follows: fat metamorphosis in 8 (11%), chronic persistent hepatitis in 20 (28%), early chronic active hepatitis in 20 (28%), advanced chronic active hepatitis in 15 (21%), and hemosiderosis in 9 (12%). There was no statistical correlation between the serum enzyme levels and the histologic diagnosis. During a mean follow-up of 5.7 +/- 3.9 years, clinical progression to hepatic failure and death occurred in 35% of patients with early chronic active hepatitis, 55% with hemosiderosis, and 60% with advanced chronic active hepatitis. None of the patients with the morphologic diagnosis of fat metamorphosis or chronic persistent hepatitis died as a consequence of hepatic failure. Follow-up liver specimens were obtained in 34 (47%) of the original 72 subjects after a mean interval of 4.5 +/- 4.3 years. Of the 15 patients with the initial diagnosis of early chronic active hepatitis, 9 (60%) showed morphologic transition to advanced chronic active hepatitis, and in 1 of the 5 patients with hemosiderosis (20%), the lesion had resolved after successive phlebotomies. During the follow-up, 60% with early chronic active hepatitis (9 of 14), 66% with hemosiderosis (2 of 3), and 100% with advanced chronic active hepatitis (4 of 4) showed histologic progression to liver cirrhosis. On the contrary, no morphologic alterations were observed in the follow-up specimens of patients with fat metamorphosis or chronic persistent hepatitis. Of the different variables screened for their association with histologic progression, older age at transplant, female sex, and morphologic diagnosis of advanced chronic active hepatitis were found to be significant. CONCLUSION Histologic diagnosis can be a useful marker in predicting the course of chronic liver disease after renal transplantation. Liver biopsy should be incorporated into the evaluation and management of chronic liver disease in renal transplant recipients.

Abstract
We have previously shown that the functioning hepatocyte mass (galactose elimination capacity, GEC) and microsomal liver functions (non-renal clearances of unbound prednisolone and cyclosporin A) are impaired in renal allograft recipients (N = 28) one month and one year after successful transplantation. To assess the natural history of these hepatic functional derangements, we reinvestigated 21 patients with stable renal function three to five years following grafting. GEC remained with 6.07 +/- 0.86 mg/min x kg significantly (P less than 0.001) below that in healthy controls (7.52 +/- 0.78 mg/min x kg), but did not significantly change during follow-up (5.93 +/- 0.96 and 6.26 +/- 0.94 mg/min x kg at 1 year and 1 month, respectively). In contrast, the non-renal clearance of unbound prednisolone declined steadily during follow-up averaging 4.98 +/- 0.71 ml/min x kg at three to five (compared to 5.83 +/- 1.51 and 6.80 +/- 1.73 ml/min x kg at one year and one month, respectively). These values were lower (P less than 0.01) than those observed in healthy control subjects (7.56 +/- 1.59 ml/min x kg). The total body clearance of cyclosporin A decreased similarly with time averaging 4.5 +/- 1.2 ml/min x kg at three to five years (compared to 4.9 +/- 1.2 and 5.9 +/- 2.1 ml/min x kg at 1 year and 1 month, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The implications of hepatitis B virus (HBV) reinfection after liver transplantation were studied in 29 patients followed for 1.7-15 years. Of 20 patients with HBV infection alone, nine were HBeAg and HBV DNA seronegative and 11 had evidence of HBV replication as measured by HBeAg or HBV DNA seropositivity. Nine patients had co-existing HBV and delta virus (HDV) infection. Five patients became HBsAg seronegative after transplantation (four immediately and one after an hepatitic episode). Of the 20 patients with HBV infection alone, 17 had evidence of viral replication after transplantation with markedly increased HBV DNA levels. Five patients with HDV infection had HBV DNA in serum, but in significantly lower amounts than in those with HBV infection alone. Twenty-five episodes of graft dysfunction attributed to recurrent HBV infection occurred in 19 patients (65.5%). Thirteen episodes (in 12 patients) were self-resolving acute hepatitic illnesses. Six patients had a rapidly progressive illness leading to graft loss within 6 weeks, with the distinctive histological features termed fibrosing cholestatic hepatitis (FCH). Liver function tests in these patients showed markedly abnormal serum bilirubin and prothrombin times, but only modest increases in serum transaminase levels. An additional six patients lost their graft as a consequence of HBV recurrence through various pathogenetic mechanisms including possible (but unproven) FCH, chronic active hepatitis or late-onset hepatic failure. Co-existing HDV infection appeared to confer some medium-term protection from graft loss.

Abstract
The long-term patient and graft survivals, causes of death, complications and rehabilitation status in the second decade were analyzed in 114 patients who received living related kidney transplants and were followed up for 10 years or longer. Azathioprine and prednisolone were used for basal immunosuppressive therapy in all patients. The actual patient and graft survival rates at 10 years were 76.3 per cent and 50.9 per cent respectively, the main causes of death being serious infection (10 cases), malignant disease (5 cases), cerebral bleeding (4 cases), hepatic failure (3 cases), gastrointestinal bleeding (2 cases) and cardiovascular disorder (2 cases). Four patients died from complications after re-admission for hemodialysis. The cumulative patient and graft survival rates at 15 years in 58 patients whose graft survived for over 10 years were 87 per cent and 75 per cent, respectively. Of the 51 patients still surviving at the end of the study, the complete rehabilitation rate was 90.2 per cent, however, de novo malignant disease and hepatic disorder were significant complications which not only disturbed the patients' quality of life but also reduced their survival rate. Therefore, regular follow-up of patients and appropriate management procedures are necessary to enhance the long-term success of kidney transplantation.

Abstract
Liver biopsies were performed on 18 haemodialysis patients with clinically as well as clinico-chemically altered liver values and partially positive HBV marker serology, with the view to comparing these values with ultrastructural findings in correlation with histological and immunohistological results. The following characteristic combination of findings was recorded at ultrastructural level: hypertrophy and hyperplasia of agranular endoplasmic reticulum of hepatocytes, haemosiderin deposits in Kupffer cells and hepatocytes, invasion of lymphocytes into Disse and intercellular spaces; megamitochondria in hepatocytes and perisinusoidal fibrosis established in some cases. The same findings proved to be recordable in histological diagnosis of hepatitis or toxico-metabolic liver damage. The study shows that inflammatory lesions are not all the only causes for haemodialysis-related changes in clinico-chemical values, so that liver biopsies together with ultrastructural investigations are indicated for differential diagnosis.

Abstract
We determined the prevalence of antibodies to the hepatitis C virus (anti-HCV) in 90 patients and 37 staff members of two hemodialysis units utilizing a recently developed anti-HCV recombinant based assay. Eleven patients (12%) were anti-HCV(+). Of these, eight (73%) had antibodies to the hepatitis B core antigen (anti-HBc) indicating prior hepatitis B infection; one patient was hepatitis B surface antigen (HBsAg)(+). All staff members were anti-HCV(-), although seven (19%) of them were anti-HBc(+). Alanine aminotransferase elevations were present at the time of the study in four anti-HCV(-) patients and in only one anti-HCV(+) patient. All anti-HCV(+) (mean 59 +/- 74; range 3 to 269 units) and 85% of anti-HCV(-) patients (mean 16 +/- 27; range 0 to 204 units) had received multiple blood transfusions (P = 0.348). Among 50 patients tested for human immunodeficiency virus (HIV), 43% of anti-HCV(+) as compared to only 7% anti-HCV(-) were positive (P = 0.003). There was a history of intravenous drug abuse (IVDA) in eight (72%) of the anti-HCV(+) patients and in only seven (9%) of the anti-HCV(-) group (P = 0.00001). The results of this serologic survey suggests that anti-HCV positivity is prevalent, although much less than anti-HBc, among our dialysis patients, whereas it was not detected among staff members. The prevalence rate of anti-HCV was statistically significantly higher among anti-HIV(+) and IVDA patients but not in multi-transfused patients.

Abstract
Recent reports showing that the presence of positive tests for hepatitis B surface antigen (HBsAg) is associated with prohibitively high morbidity and mortality suggest that such patients should not be considered for kidney transplantation. The clinical outcome and serology including hepatitis B DNA assays of 11 patients who were HBsAg-positive at the time of transplantation, as well as the hepatic complications in all 200 kidney transplantations during the same period, were analyzed. In the 11 HBsAg-positive patients, no clinical or laboratory evidence suggesting deterioration in liver function over a mean follow-up period of 8.0 +/- 1.7 years was found. Of six patients with fatal or severe chronic liver disease, only one was HBsAg-positive at the time of transplantation and showed no deterioration over 9 years. Two immunosuppressed patients developed anti-HBs antibodies after acute hepatitis B infection. A review of the literature leads to the conclusion that previous reports of poor patient prognosis may represent patients who first showed HBsAg positivity after transplantation or who had preexisting HBsAg-related liver disease. The present findings suggest that asymptomatic patients with positive tests for HBsAg should not be excluded from kidney transplantation programs.

Abstract
Hepatitis B virus (HBV) markers were determined in 821 patients receiving renal allografts and undergoing immunosuppressive therapy during 1970-1986. Twenty-four of the patients with a renal transplant functioning for longer than 1 year originally were or became chronic carriers of hepatitis B surface antigen (HBsAg). These patients remained carriers during the follow-up period, which lasted until death or until the end of 1986. Follow-up time was 1.2-15.3 years (mean 9.1 years). A total of 301 samples from the HBsAg-positive patients were tested for HBV DNA and HBeAg/DNA and HBeAg/anti-HBe. Nine patients who were constantly positive for HBeAg also remained positive for HBV DNA. Reactivation of HBV replication occurred in 11 patients. Among these, HBV DNA and HBeAg varied in parallel in six patients, three patients developed anti-HBe, and two patients were constantly positive for anti-HBe. Another four of the 24 patients seroconverted to anti-HBe, and two of these also lost HBV DNA. Three of 12 deceased patients died from liver failure during follow-up. None of these three had been constantly positive for HBeAg or HBV DNA, but they had had reactivations of HBV; two were also positive for HBV DNA in serum specimens available from their terminal month. HBV DNA was demonstrated in 99% of HBeAg-positive and 53% of anti-HBe-positive sera and in at least two samples from each of the 24 patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Hepatic failure as a cause of death is increased in stable renal allograft recipients when compared with patients on dialysis. In order to assess the magnitude and the natural history of the hepatic functional derangement, the kinetics of xenobiotics which are metabolized by cytosolic (galactose) or microsomal (prednisolone, cyclosporine A) enzymes were determined in 28 consecutive stable kidney transplant patients 1 month and 1 year after transplantation. Renal transplant patients had a decreased mean (+/- S.D.) galactose elimination capacity at 1 month (6.26 +/- 0.94 mg per min x kg) and at 1 year (5.93 +/- 0.96 mg per min x kg), when compared with a different group of 28 healthy control subjects (7.52 +/- 0.78 mg per min x kg, p less than 0.001) and a decreased total body clearance of prednisolone at 1 month (2.13 +/- 0.34 ml per min x kg vs. 2.71 +/- 0.43 ml per min x kg in controls, p less than 0.001), which further decreased over the following year to 1.76 +/- 0.32 ml per min x kg (p less than 0.001). The clearance of cyclosporine A declined significantly during the first year of successful transplantation (5.9 +/- 2.1 ml per min x kg vs. 4.9 +/- 1.2 ml per min x kg, p less than 0.05). In conclusion, a substantial proportion of stable renal transplant recipients have decreased cytosolic and microsomal liver functions despite the absence of clinical and laboratory evidence of significant liver disease.

Abstract
Hepatitis B virus (HBV) infection may induce severe hepatitis and affect long-term survival of kidney transplant recipients. Persistent viral infection has been shown to occur despite the absence of usual serologic markers. The liver and serum HBV deoxyribonucleic acid (DNA) status of 90 patients were studied prospectively; recently transplanted patients, both hepatitis B virus surface antigen (HBsAg)-positive and negative, with and without liver disease, were investigated with HBV serology, serum HBV DNA, and liver histology. Thirty-four patients had detectable HBsAg, and 21 had viral multiplication at the time of transplantation. Serial HBV DNA determinations performed in 57 of 90 patients disclosed (a) reactivation of HBV replication in 11 of 12 HBsAg-positive patients, (b) increase of viral replication when positive on the initial sample in 6 of 11 patients, and (c) development of HBV replication in 7 of 35 of the HBsAg-negative patients. Moreover, liver HBV DNA studies showed a statistical correlation between the presence of integrated liver HBV DNA and chronic hepatitis in HBsAg-negative patients. This study demonstrates prospectively the significant association of HBsAg-positive as well as HBsAg-negative HBV infection with chronic hepatitis and suggests that immunosuppressive therapy may enhance the viral replication in both HBsAg-positive and negative subjects.

Abstract
One hundred one patients established on chronic hemodialysis on January 1, 1978, were retrospectively evaluated over the ensuing 8-year period to determine the effect of hepatitis B surface antigenemia on morbidity and mortality. Sixty-four patients remained HBsAg-negative after reaching end-stage renal disease; 30 were transiently or persistently HBsAg-positive; seven patients were excluded from study because of insufficient data. The HBsAg-positive and HBsAg-negative patients did not differ with respect to age, sex, race, or etiology of renal disease. There were no differences between the positive and negative groups in terms of death rates (50% v 34.4%, P = not significant), causes of death, hospitalizations (1.5 v 1.2/patient/yr), or hospitalized days (18.0 v 11.8 patient/yr). Only mild liver enzyme elevation (SGOT) was observed at the time of conversion in 13 patients with enzyme abnormalities who seroconverted after beginning hemodialysis (mean SGOT 255 micron/mL). No patient had persistent liver enzyme elevation over the 8-year period. These data suggest that chronic hepatitis B surface antigenemia is not, in itself, associated with increased morbidity or mortality in a chronic hemodialysis population.
