To delineate the natural clinical course of spontaneous bacterial peritonitis in hepatitis B-related cirrhosis and to determine if it occurs in hepatocellular carcinoma, a prospective survey was conducted in 262 patients over 2 1/2 years. The in-hospital incidence and mortality rates of spontaneous bacterial peritonitis were 21.6% and 36.4%, respectively, in cirrhosis and 7.3% and 50% in hepatocellular carcinoma. In cirrhosis, the cumulative probability of annual recurrence of spontaneous bacterial peritonitis was 47.3%, which was significantly higher than the annual probability of occurrence of 11.3% in those with no previous attack (P less than 0.0001). The cumulative probability of annual survival was 27.6% in the spontaneous bacterial peritonitis patients, significantly lower than the probability of 64.0% in the control group (P = 0.0001). A univariate analysis, with Kaplan-Meier curves compared by the Mantel-Cox test, and subsequent multivariate analysis by stepwise Cox regression procedure were used to evaluate 37 variables recorded immediately after admission. Blood urea nitrogen concentration greater than 10.5 mmol/L urea (greater than 30 mg/dL) and ascitic fluid protein concentration less than 7.35 g/L (less than 735 mg/dL) were found to be the only significant predictors of lower annual survival; ascitic fluid protein concentration less than 7.50 g/L (less than 750 mg/dL) was the only significant predictor of higher annual recurrence. The authors conclude that spontaneous bacterial peritonitis has a high risk of recurrence in hepatitis B-related cirrhosis and that the same disease occurring in patients with hepatocellular carcinoma is related to the underlying cirrhosis rather than the hepatocellular carcinoma.

Endogenous bacterial endophthalmitis occurred in a hepatitis B virus carrier during an episode of severe hepatitis complicated by anaerobic septicemia and possible spontaneous bacterial peritonitis. This may well represent another complication of severe hepatitis with anaerobic bacteremia.

We conducted a prospective, randomized trial to study the efficacy and tolerance of long-term versus short-term treatment with recombinant interferon alfa-2a in patients with chronic hepatitis B. Ten patients were randomly assigned to a 6-month interferon regimen, and 10 patients were assigned to a 3-week interferon trial. Eleven patients (five assigned to long-term treatment and six to short-term treatment) did not complete interferon therapy: eight had either severe thrombocytopenia or neutropenia; one had pronounced fatigue in relationship to administration of interferon; one had spontaneous bacterial peritonitis and sepsis and died; and one had a massive fatal variceal hemorrhage during interferon therapy. Most of the serious hematologic complications occurred in patients with cirrhosis and hypersplenism. In one patient, seroconversion to hepatitis B virus DNA negativity occurred before the onset of treatment. Four of the five patients able to complete the 6-month interferon regimen and only one of four patients able to complete the 3-week trial had seroconversion to hepatitis B virus DNA negativity. Thus, we conclude that the therapeutic response was better among patients who were able to complete a 6-month interferon trial. In patients with cirrhosis and hypersplenism, development of either severe thrombocytopenia or leukopenia associated with interferon therapy precluded completion of treatment.

Fifty-six patients with biopsy-proven, chronic active hepatitis B were included in a multi-center, randomized trial comparing steroid withdrawal followed by 1.5 MU recombinant interferon alpha 2b (Intron) with placebo withdrawal followed by either 1.5 or 5 MU interferon. The patients were equally distributed between the treatment groups with respect to biochemical and histologic activity as well as with respect to DNA levels and quantitative liver function tests. One patient was lost to follow up. After 1 year of treatment, 10/18, 13/19 and 11/18 patients had lost hepatitis B virus DNA in the three groups, respectively (non-significant). Transaminase levels were normal in 27/34 of the responders but in only 4/21 of the non-responders (p < 0.0001). Both galactose elimination capacity and aminopyrine breath test improved significantly in responders, but either did not change (aminopyrine breath test) or deteriorated in non-responders (galactose elimination capacity). Biopsy score improved in both groups but this reached statistical significance only in responders. This effect was due to improvements in both inflammatory and fibrotic activity. Side effects included almost universally a flu-like syndrome, granulocytopenia (1), depression (3) and thyroid dysfunction (2). Two deaths occurred, one due to hepatocellular cancer, and the other to hepatorenal syndrome after spontaneous bacterial peritonitis. A severe cytolytic episode was observed in three patients in the steroid withdrawal group. We conclude that in patients with marked histologic activity, lower doses of interferon may be as effective as the standard dose of 5 MU.(ABSTRACT TRUNCATED AT 250 WORDS)

The prevalence of hepatitis C virus (HCV) infection in patients with chronic liver disease (CLD) in Israel has not yet been reported. A retrospective analysis was performed on the first 92 consecutive patients referred to our Liver Unit with serologically confirmed antibodies to hepatitis C virus (anti-HCV) who had evidence for chronic hepatitis, cirrhosis, and hepatocellular carcinoma. We compared 31 patients who were anti-HCV positive with 61 patients who had evidence for both previous or present infection with hepatitis B virus (HBV) as well as HCV. Dual infection was significantly more prevalent in Jewish patients of non-Ashkenazi origin, who were also characterized by higher rates of portal hypertension manifested by ascites, bleeding esophageal varices as well as hepatic encephalopathy and spontaneous bacterial peritonitis. We conclude that dual infection of HBV and HCV was found in 66% of patients with anti-HCV positive liver disease in Jerusalem, and that these patients develop more serious complications than CLD patients with anti-HCV alone.

The purposes of this paper is to review the specific role of peritoneal dialysis (PD) in patients with liver disorders. We will pay attention to the confluence of liver diseases and situations for which chronic dialysis treatment is required. Hemodialysis (HD) and peritoneal membranes are safe barriers against the passage of the hepatitis C virus; consequently, while peritoneal effluent or HD ultrafiltrate drained from hepatitis B patients/carriers is infective, that from hepatitis C patients does not appear to present this risk. An important issue is horizontal transmission, which appears to occur with both viruses in HD units, and which is absent in peritoneal dialysis units. The incidence of hepatitis C among continuous ambulatory peritoneal dialysis (CAPD) patients is quite low, while it may reach almost 50%-60% of HD patients in some units. While hepatitis C transmission mechanisms are not completely understood and a vaccine is not available, PD provides some degree of protection when compared with HD, for and-stage renal disease patients. In summary, our experience and that of others, with a total of 19 PD-treated chronic liver disease patients, supports CAPD as the treatment of choice for cirrhotic patients with ascites who require chronic dialysis. Data on peritoneal diffusion of low molecular weight substances revealed a marked increase in most patients. The ultrafiltration capacity was clearly augmented with respect to noncirrhotic patients, making the use of hypertonic bags unnecessary. Hemodynamic tolerance was excellent. Complications and death were mainly related to liver disease complications. Spontaneous bacterial peritonitis (SBP), caused by gram-negative germs, is the most important complication directly related to ascites and may have some points in common with PD-related peritonitis. However, and in contrast to most PD peritonitis, two pathogenetic mechanisms have been suggested for SBP: (1) translocation of bacteria from the gut to the mesenteric lymph nodes, and (2) bacteremia in these patients is secondary to the general abnormal host defense mechanisms. Local factors such as intrahepatic shunting and the impairment of bactericidal activity in ascitic fluid favor the bacteria ascites. The hypothesis of a direct transmural contamination from bowel to ascitic fluid has been relegated to secondary bacterial peritonitis. Would cirrhotic patients with temporal or permanent renal function compromise benefit from peritoneal catheter placement and other PD practices to perform repetitive small ascitic drainages at home? Perhaps the time has arrived when hepatologists and PD nephrologists begin to work shoulder to shoulder in this particular field, as we have a common problem, the peritoneal cavity filled with fluid.

Mannose-binding lectin (MBL) plays an important role in immune defense. We examined the MBL gene mutations and MBL levels in Chinese hepatitis B and hepatitis C patients with and without symptomatic cirrhosis. We recruited 190 hepatitis B and C patients, and 117 normal Chinese as controls. Serum MBL levels were measured by enzyme-linked immunosorbent assay. MBL gene mutation at codons 52, 54, and 57 was detected by polymerase chain reaction (PCR) assay. In asymptomatic hepatitis B and C patients, there was no increase in codons 52, 54, and 57 mutation, but the MBL levels were significantly lower than those in the controls. Codon 54 mutation rate was increased to 44.4% (P =.007) in symptomatic hepatitis B cirrhosis and 64.3% (P =.0026) in patients with spontaneous bacterial peritonitis (SBP). There was no increase in codon 54 mutation rate in hepatitis B-related hepatocellular carcinoma (HCC). In chronic hepatitis B infection, the odds ratio for an individual with codon 54 mutation to develop cirrhosis was 1.84 (95% CI: 1.21-2. 81) and to develop SBP was 4.58 (95% CI: 1.73-12.16). Chronic hepatitis B and hepatitis C infection lowered the MBL levels, probably by suppressing MBL production. Codon 54 mutation of MBL was associated with progression of disease in chronic hepatitis B infection.

Spontaneous bacterial peritoneal infections is recognized as a very common complication of cirrhotic ascites, but isolation of fungus in pure culture from ascitic fluid is relatively rare, even more so in the human immunodeficiency virus (HIV)-negative or nonimmunocompromised hosts. We describe two patients of spontaneous fungal peritonitis where the isolate was Cryptococcus neoformans. Both cases suffered from hepatitis B virus (HBV) infection. The clinical and laboratory profiles of both patients were similar to those of conventional spontaneous bacterial peritonitis. We suggest that it would be prudent to heighten clinical suspicion for fungal peritonitis in such cases.

The general indications for liver transplantation in hepatitis B virus (HBV) and hepatitis C virus (HCV) infection, and the issues surrounding treatment for HBV infection in the pre- and post-transplant periods, are discussed. In general, transplantation is reserved for patients with end-stage liver failure secondary to cirrhosis and a small population with acute liver failure. It is proposed that certain guidelines can be developed and that these should include any one of the following: a Child-Pugh score > or = 9, diuretic resistant ascites, recurrent portal hypertensive bleeding, recurrent encephalopathy, spontaneous bacterial peritonitis and the development of a small hepatocellular cancer (< or = 5 cm in diameter). Treatment for HBV infection now includes lamivudine therapy pre and post transplantation together with hepatitis B immunoglobulin. Such an approach has virtually abolished recurrence of HBV infection following liver transplantation.

Fibrosing cholestatic hepatitis is a deleterious manifestation of hepatitis B virus infection in immunocompromised patients. Without treatment, this condition is usually fatal within weeks of onset. Liver retransplantation has not been successfully performed to date, and treatment intervention was generally unsuccessful before the advent of adefovir dipivoxil. However, concerns have been expressed about the use of this agent in patients who are renally compromised. A 40-year-old liver transplant recipient with hepatitis B virus reinfection, resistance to lamivudine, and fibrosing cholestatic hepatitis complicated by terminal renal impairment and spontaneous bacterial peritonitis was treated with adefovir dipivoxil 10 mg after every dialysis. Since initiating treatment with adefovir dipivoxil 10 mg, a dramatic virologic and clinical improvement was observed in this patient. The patient returned to work full-time within 6 months of starting adefovir dipivoxil without the need for liver retransplantation. Serum HBV DNA (Amplicor HBV; Roche Diagnostics, Basle, Switzerland) decreased by 6 log(10) copies/mL and became negative (< 400 copies/mL) within 8 weeks of treatment and remains negative at the last available assessment. The patient continues to require renal dialysis, but is generally well. Creatinine clearance improved from 8 mL/min to 16 mL/min during the course of treatment. No adverse events related to adefovir dipivoxil were observed. Adefovir dipivoxil resulted in significant clinical improvement in this patient with hepatitis B virus-induced fibrosing cholestatic hepatitis, despite the presence of renal impairment and lamivudine resistance.
