To assess the prevalence and long-term impact of HCV on kidney transplant recipients, we assayed 716 pre-transplant sera using a first-generation ELISA. The anti-HCV positive sera were confirmed by a 6-antigen radioimmunoassay (RIA). Patients were followed up for 5 years. Graft survival, function, evidence of chemical hepatitis (AST > 2x normal), patient mortality and cause of death were evaluated. The prevalence of anti-HCV antibody was 10.3%. In the 638 patients who were followed up for 5 years, there were no differences in graft function, graft survival, overall mortality, or death from sepsis or liver disease. Peak AST levels were significantly higher in anti-HCV positive patients compared to anti-HCV negative patients. At 5 years, the AST levels remained significantly higher in the anti-HCV positive group, however, this was only 6 U/1 > normal. Liver biopsies performed 3 to 7 years post-transplant in 80% of anti-HCV positive patients with chemical hepatitis showed 12% CAH, 50% mild hepatitis and 38% normal histology. Six (9.7%) patients seroconverted from anti-HCV positive to anti-HCV negative 2 to 5 years post-transplant. The presence of anti-HCV does not appear to alter long-term patient or graft survival, and histologic evidence of severe chronic liver disease was rare in anti-HCV positive patients with chemical hepatitis. From these results, the presence of anti-HCV antibody should not preclude kidney transplantation.

There is a high incidence of chronic liver disease in end-stage renal failure patients on dialysis. Hepatitis C virus appears responsible for 80% of posttransfusion hepatitis, and up to 80% of sporadic hepatitis and cryptogenic cirrhosis. Anti-HCV antibodies correlate highly with the presence of active infection. The clinical implications of HCV infection in patients undergoing renal transplantation is unknown. Part I: We undertook a descriptive cross-sectional study of all renal failure patients admitted for kidney transplant between 1/84 and 12/88. Pretransplant sera were assayed for anti-HCV using an ELISA. Patients were divided into anti-HCV-positive (study group) and anti-HCV-negative (controls). Part II: A cohort study was performed with both groups followed from the time of transplantation to the present. Comparisons were made by t tests, chi-square analysis with Yates correction, Mann Whitney test for nonparametric results and multiple regression analysis. Part I: Anti-HCV was present in 76 of 716 sera assayed. There were no differences in sex, age, number of previous transplants, and underlying renal disease. Four variables predicted the presence of anti-HCV: number of blood transfusions; duration on dialysis; i.v. drug abuse, and nonwhite race. Part II: A group of 596 patients was further analyzed. The mean duration of follow-up was not different between the two groups. There were no differences in graft survival, overall mortality, or mortality secondary to liver disease or sepsis. Based on these results, the presence of anti-HCV should not be a contraindication for kidney transplantation.

Vibrio vulnificus infection, which is a rare and fatal disease, can be categorized clinically as either primary septicemia or wound infection. The clinical presentation of patients with primary septicemia can vary from fever alone to a more severe illness including high-grade bullous lesions, hypotension, and shock. Wound infection typically results from either injury to the skin in a marine environment or contact of a preexisting wound with sea water. We reported eight cases with Vibrio vulnificus infection in Chang gung Memorial Hospital and reviewed ten other cases previously reported with details in Taiwan. Fourteen patients presented with primary septicemia, and four with wound infection. Thirteen patients had alcoholism or chronic liver disease, two had peptic ulcer disease, one was steroids abuser, and one patient had thalassemia and chronic liver disease. Overall mortality was 55.6% (ten patients). Patients with hypotension within 48 hours of admission had higher mortality than normotensive patients (77% vs. 0%, P = 0.007). Patients with chronic liver disease or liver cirrhosis also had tendency to a higher mortality than not (64% vs. 25%, P = 0.274). Chronic liver diseases and liver cirrhosis are common disease in Taiwan. They take a high risk for Vibrio vulnificus infection. Clinician should keep in mind of this potentially fatal infection in these patients reporting a history of recent raw oyster consumption and presented with sepsis and characterized skin lesions. Prompt empirical antibiotics treatment and aggressive surgical treatment may be lifesaving for this acute and fatal disease.

Vibrio vulnificus is an etiologic agent of septicemia and skin lesions. Patients with chronic diseases, and more frequently chronic liver disease, are specially susceptible to this infection. The main risk factor is shellfish ingestion. In this report we present a patient with chronic liver disease who suffered fulminant sepsis and necro-hemorrhagic bullaes secondary to a V. vulnificus infection. The patient had ingested shrimps two days before. A review of the recent literature on the subject is also presented.

Functional hyposplenism, seen in some patients with alcoholic liver disease, may contribute to the increased susceptibility to infections. As hyposplenism does not complicate non-alcohol related chronic liver disease, it is probably secondary to a toxic effect of alcohol. Over a two year period the case notes of 82 patients with alcoholic liver disease, whose splenic function had been assessed by the counting of pitted erythrocytes using differential interference microscopy, were reviewed to monitor mortality and the effects of hyposplenism. Thirteen patients (seven with hyposplenism) had serial measurements of pitted erythrocyte count made to assess the effect of abstinence from alcohol on splenic function. Thirty one of the 82 alcoholic patients had pitted erythrocyte counts greater than 2%. Eighteen of 82 (16%) patients died over the two years and 11 of these had been unable to stop drinking. Only one patient died of sepsis. Five patients (6%) had pitted erythrocyte counts comparable with those in splenectomised patients. In 12 of 13 patients who had abstained from alcohol for two months, the pitted erythrocyte count fell from a median of 3 to 1.3% (mean: 8.1 to 2.6%. p = 0.01). The pitted red cell count in two patients increased. One had abstained, the other had continued to drink heavily. Short term mortality in alcoholics is high, particularly if they continue to drink heavily. Only a few of these deaths are secondary to infection. Splenic function, as assessed by these methods, improves in most patients with abstinence, suggesting that the functional hyposplenism may be a result of a direct toxic effect of alcohol on the spleen.

We recently saw two unusual manifestations of Haemophilus influenzae infection in adults in the Seattle area: fulminant sepsis in an otherwise-healthy man and three episodes of bacteremia in a woman with chronic liver disease. We retrospectively identified 79 bacteremic and 40 non-bacteremic cases of invasive H. influenzae infection developing in patients > or = 9 years of age between 1 January 1980 and 31 December 1990. The most common clinical presentations among patients with bacteremia included pneumonia (52%), septicemia (27%), meningitis (8%), gynecologic infection (5%), and epiglottitis (5%). Underlying illnesses were common in these patients, and overall mortality was 35.5%. Factors associated with mortality included underlying neurological disease, polymicrobial bacteremia, and advanced age. The clinical presentations of the 40 patients without bacteremia included soft-tissue abscesses (45%), lung abscesses (18%), peritonitis (13%), meningitis (8%), gynecologic infection (8%), epididymitis (5%), mastoiditis (3%), and osteomyelitis (3%). Thus H. influenzae disease has a variety of presentations and is associated with significant mortality in older children and adults. Further study is required to determine whether widespread administration of H. influenzae type b conjugate vaccine to infants will alter the development of subsequent disease in later life.

Chronic liver disease is accompanied by a number of circulatory changes including impairment of cardiovascular autonomic reflexes. This occurs irrespective of the aetiology of liver disease, increases in prevalence and severity with worsening hepatic function, and is related at least in part to an autonomic neuropathy. Parasympathetic abnormalities predominate and, although largely subclinical, they may play a role in the altered fluid homeostasis and neurohumoral disturbances associated with cirrhosis. On prospective follow up, the presence of autonomic impairment was associated with a five-fold increased mortality, largely from sepsis and variceal haemorrhage. Defective responses to such stressful events as a result of an afferent defect could possibly explain these findings. Further studies are required to evaluate the natural history of this complication, and determine if it is reversible with improvement in hepatic function or after liver transplantation.

Thirteen orthotopic liver transplantations were performed in 12 patients for hepatic complications of Wilson's disease between May 1988 and July 1992. Ten patients had fulminant hepatic failure and two chronic liver disease. One patient underwent retransplantation for liver abscess secondary to hepatic artery thrombosis. Nine patients survive at a median follow-up of 18 (range 6-31) months. Three patients have died: two from multiple organ failure and sepsis, one from B cell lymphoma. Postoperative complications included bleeding requiring laparotomy in two patients, renal impairment in five, bacterial septicaemia in three, fungal sepsis in two and acute cellular rejection in six. The nine surviving patients are well with normal liver function test results.

Hepatitis C virus (HCV) is a major cause of posttransplantation chronic liver disease. The aim of this study was to evaluate the prevalence of HCV in renal transplant recipients and to investigate risk and prognostic factors. Of 427 renal transplants carried out between July 1983 and January 1993, we retrospectively studied 66 (15.5%) HBsAg-negative patients with anti-HCV detected by enzyme-linked immunosorbent assay (ELISA) and recombinant immunoblot assay (RIBA). Patient and graft survivals were estimated. Anti-HCV positive patients had more time on hemodialysis and pretransplant blood transfusions (P = 0.0001) than did the seronegative population. In a mean follow-up of 52.3 +/- 27.7 months, 36 patients (54%) had biochemical evidence of liver disease, predominantly with a persistently high pattern of serum alanine aminotransferase (ALT). Pretransplantation ALT elevation was associated (P = 0.004) with chronic liver disease (CLD) in the graft recipient. None of the other variables studied predicted posttransplantation CLD. Liver failure occurred in two (3%) and was the cause of death in one of the patients. Death occurred in eight significantly more aged (P = 0.0001) patients, at 45.5 +/- 28.8 months posttransplant. In 50% of the cases, death was ascribed to sepsis. The biochemical pattern of HCV showed no predictive value for prognosis. The disease had no significant effect on the number of rejections or graft survival. The study revealed lower actuarial survival (P = 0.004) for HCV-positive patients in comparison with the seronegative population.

To assess the impact of chronic viral hepatitis on host immune response, we analyzed the incidence of acute rejection and the frequency of infections in 86 patients infected with hepatitis B and C viruses and had developed clinical evidence of chronic liver disease and 1283 control patients who were transplanted at our center during the same period, but had no evidence of chronic viral hepatitis. To compare the mean number of rejections and the mean number of infections between the two groups, we used multivariate linear regression analysis, which allowed us to adjust simultaneously for the effects of 10 other risk variables with potential impact on graft rejection and posttransplant infection. During a mean follow up of 5.3+/-5.2 years, 62% of hepatitis patients and 54% of control patients had experienced an acute rejection (P=NS). The mean rejections/patient in the hepatitis group was 1.3+/-0.14 versus 1.03+/-0.03 in control (P=NS). In the linear regression analysis, the number of acute rejections in the hepatitis group was 0.16 higher than in control (P=NS). With reference to infection, 84% of hepatitis patients experienced an infectious complication in the posttransplant period, compared with 75% in the control (P=0.05). The mean number of infections/patient was 5.7+/-0.73 in the hepatitis group compared with 3.9+/-0.14 in the control group (P=0.002). The linear regression model had shown that the hepatitis group had a relative increase of 1.18 infections/pt, compared with control. Of the different sites of infection, the hepatitis group had a significant increase in bloodstream (0.48+/-0.08 vs. 0.25+/-0.02) P=0.003; pulmonary (0.60+/-0.09 vs. 0.38+/-0.03) P=0.03; and CNS infections (0.08+/-0.03 vs. 0.02+/-0.004) P=0.05 compared with control. Among the different microorganisms causing infection, the hepatitis patients had a significant increase in gram negative bacterial infections compared with the control group (74% vs. 61%) P=0.04. Our data suggest that chronic viral hepatitis is associated with a significant increase in overall infections, and that of potentially fatal infections involving CNS, lungs and bloodstream. Since there is no significant increase in the rate of graft rejection, one could consider a cautious reduction in the doses of maintenance immunosuppressive agents in renal transplant patients with chronic viral hepatitis. The reduced immunosuppression may in turn lower the death rate from sepsis and progressive hepatic failure.
