Lamivudine Therapy for Decompensated Liver Cirrhosis Related to Hepatitis B Virus Infection

Chronic hepatitis B virus (HBV) infection is the major cause of chronic liver disease worldwide. Although the clinical course of HBV infection varies widely, the prognosis of decompensated liver cirrhosis is quite poor and the 5-year survival rate has been estimated to be only 14-35%. While the ultimate treatment of decompensated cirrhosis is orthotopic liver transplantation (OLT), recent studies have suggested that lamivudine can also improve the clinical outcomes in this group of patients. Lamivudine rapidly suppresses HBV replication and can improve several parameters of liver function tests and afford prolonged periods of pretransplantation survival. However, the proportion of clinical improvement as defined by a decrease in Child-Pugh score as well as the prolonged survival rate varied widely from study to study. These discrepancies might result from differences in the severity of cirrhosis at entry, the presence of active viral replication or inflammation, and the proportions of patients who received OLT during the study period. Overall, about half of the patients achieved a clinical improvement with lamivudine therapy. However, data are still lacking on whether lamivudine can prolong survival before OLT and even replace OLT. Most of the deaths or clinical improvement occurred or started to occur within the first 6 months of treatment. Therefore, OLT should be actively considered in patients with risk factors for early mortality or those without clinical improvement within the first 6 months of lamivudine treatment.

HIV-1, hepatitis B virus, and risk of liver-related mortality in the Multicenter Cohort Study (MACS)

BACKGROUND

Although coinfection with HIV-1 and hepatitis B virus (HBV) is common, few long-term studies on liver-disease mortality in coinfected people have been undertaken. Our aim was to examine liver-related mortality among people at risk for HIV-1 and HBV infections.

METHODS

We used data from a multicentre, prospective cohort study to classify 5293 men who had sex with men, according to their HIV-1 antibody status, ascertained semiannually, and their hepatitis-B surface antigen status (HBsAg), which we ascertained at baseline. Mortality rates were estimated in terms of person-years and Poisson regression methods were used to test for significance of relative risks.

FINDINGS

326 (6%) men were HBsAg positive, of whom 213 (65%) were HIV-1 positive. Of the 4967 HBsAg negative men, 2346 (47%) were infected with HIV-1. The liver-related mortality rate was 1.1/1000 person years, and was higher in men with HIV-1 and HBsAg (14.2/1000) than in those with only HIV-1 infection (1.7/1000, p<0.001) or only HBsAg (0.8/1000, p<0.001). In coinfected individuals, the liver-related mortality rate was highest with lower nadir CD4+ cell counts and was twice as high after 1996, when highly active antiretroviral therapy (HAART) was introduced.

INTERPRETATION

Individuals coinfected with HIV-1 and HBV, especially those with low CD4+ nadir counts, are at increased risk for liver-related mortality, underscoring the importance of prevention, identification, and comprehensive management of hepatitis B in people infected with HIV-1.

Efficacy of lamivudine therapy for advanced liver disease in patients with precore mutant hepatitis B virus infection awaiting liver transplantation

BACKGROUND

Orthotopic liver transplantation (OLT) for end-stage liver disease resulting from hepatitis B virus (HBV) infection is associated with a high rate of recurrence and reduced survival. Lamivudine is effective in inhibiting HBV replication in patients with chronic hepatitis. This study evaluated the impact of lamivudine on viral suppression, liver function, and disease severity in patients awaiting OLT with HBV e-minus strain infection.

METHODS

Twenty-five patients received lamivudine (100 mg per day) from the day of listing for OLT. All patients were positive for serum HBV-DNA by polymerase chain reaction and all had a Child-Pugh score of 7 or higher.

RESULTS

Patients were followed for 12+/-9 months (mean +/- SD). Eleven underwent OLT within 13 months of treatment initiation, one died after 10 months, and one dropped out after 3 months. After 3, 6, and 9 months, HBV-DNA by polymerase chain reaction was undetectable in 14 of 25, 14 of 20, and 13 of 15 patients, respectively. Two patients developed lamivudine resistance after 9 and 18 months of treatment, respectively, without liver decompensation. Comparing baseline to last visit data, a significant improvement in prothrombin activity (43+/-15% vs. 52+/-19%; P=0.0014), serum bilirubin (3.4+/-1.9 vs. 2.5+/-2.2 mg/dL; P=0.0007), serum albumin (3.3+/-0.3 vs. 3.6+/-0.5 g/dL; P=0.0278), presence of ascites (15/25 vs. 7/25; P=0.0047), and Child-Pugh score (9 vs. 8; P=0.0003) was observed. Because of liver function improvement, four patients were placed on low priority status for OLT (United Network of Organ Sharing 3) and 9 on inactive status (United Network of Organ Sharing 7). The overall probability of survival at 6 and 12 months was 100% and 90.9%, respectively.

CONCLUSIONS

Lamivudine has an important role in patients with end-stage liver disease caused by HBV precore mutant strain. Not only does HBV-DNA suppression allow patients to be eligible for OLT, but the improvement of the patients' clinical status may delay the need for OLT in an era of organ shortage.

Detection of precore-mutant hepatitis B virus genome in patients with acute and fulminant hepatitis using mutation site-specific assay (MSSA)

BACKGROUND/AIMS

Precore mutation of hepatitis B virus was recently been suggested to be involved in the pathogenesis of fulminant hepatitis. In this study, we analyzed the occurrence of precore mutants in patients with acute and fulminant hepatitis B using new simple rapid and sensitive MSSA (mutation site-specific assay) and evaluated this method for predicting prognosis.

METHODOLOGY

We analyzed HBV-DNA of 10 patients with fulminant hepatitis B, 15 patients with acute self-limited hepatitis, and 4 patients with acute severe hepatitis using MSSA. Precore point mutation (G to A; 83rd base of precore region) was examined using a mutation-trapped oligonucleotide primer, which would yield a polymerase chain reaction amplification product only with precore mutants.

RESULTS

We distinguished precore mutants from wild type according to the presence or absence of the band at 203 bp, which was amplified in only precore mutants by polymerase chain reaction. Mutation of the precore region was observed in all 10 patients with fulminant hepatitis, in 3 of the 4 patients with severe hepatitis, and 11 of 15 patients with self-limited hepatitis. Negative pre-C mutants in patients with HBeAg indicates good prognosis of hepatitis.

CONCLUSIONS

Precore mutant strains of HBV-DNA play an important role but are not specific for fulminant hepatitis, and the mere presence of precore mutants may not directly lead to fulminant hepatitis or severe hepatitis. However, this method is useful for predicting outcome of patients with acute HBV hepatitis, especially in HBeAg-positive state.

Hepatitis B virus infection in drug addicts: no acute fatalities, no chronicity and could have benefits

In a group of 159 drug addicts with acute hepatitis B in the 1970s there were no fatalities. During an observation period of about 25 years, 51 of the 159 died of various causes, but no deaths could be attributed to the hepatitis B infection. From 1998 to 2001, a follow-up examination of 53 of the 108 patients still alive, none of the 53 had a chronic hepatitis B virus infection. Fifteen out of thirty-five patients who had completely stopped using narcotics claimed that hospitalisation for acute hepatitis B had been an important factor in their decision to quit drugs.

Increasing applicability of liver transplantation for patients with hepatitis B-related liver disease

Liver transplantation in patients with hepatitis B has been under discussion for 20 years because of inferior results without reinfection prophylaxis; therefore, we analyzed our overall experience with liver transplantation in hepatitis B patients with immunoprophylaxis, particularly the influence of the available antiviral treatment in different periods. From 1988 to 2000, 228 liver transplants in 206 hepatitis B patients were performed. Indications were acute liver failure (10%), hepatitis B virus (HBV) cirrhosis alone (67%) or with hepatitis D virus (HDV) (13%), or hepatitis C virus (HCV) coinfection (7%). All patients received long-term immunoprophylaxis (anti-HBs > 100 U/L). HBV DNA-positive patients were treated before and after surgery with famciclovir or lamivudine since 1993 and 1996, respectively. Since 1993, antivirals also were used for HBV reinfection. The 1-, 5-, and 10-year patient survival rates were 91%, 81%, and 73%. In patients with hepatocellular carcinoma (HCC) (60% 5-year survival, P <.01) or HBV reinfection (69% 5-year survival, P <.01) survival was significantly impaired. Those with HDV or HCV coinfection had a slightly better survival than with HBV monoinfection (P >.05, not significant). Preoperative positive HBV DNA (hybridization-assay) test results were associated with a slightly impaired patient survival (78% 5-year survival, P >.05, not significant versus DNA-negative). Preoperative positive hepatitis B e antigen (HBeAg) predicted significantly worse survival (P <.05 versus negative HBeAg). Graft loss caused by reinfection was most frequent before the availability of antiviral drugs. Two-year patient survival increased from 85% in era I (1988-1993) to 94% in era III (1997-2000, P <.05). The 2-year recurrence rates in these 2 periods were 42% and 8% (P <.05). In conclusion, excellent long-term results can be achieved in hepatitis B patients after liver transplantation with modern strategies, and survival rates are similar to other indications. Based on our experience, hepatitis B patients, including those with active viral replication, should not be excluded from liver transplantation.

Liver transplantation at the Sun Yat-Sen University of Medical Sciences in China

OBJECTIVES

To summarize the results of liver transplantation for various end-stage liver diseases at the Sun Yat-Sen University of Medical Sciences (SUMS), define the role of liver transplantation in the treatment of hepatocellular carcinoma and fulminant hepatitis B, and assess the efficiency of lamivudine on preventing HBV recurrence.

METHODS

Seventy liver transplants performed at the SUMS between April 1993 and December 2000 were retrospectively analyzed. The main indications for liver transplant were hepatocellular carcinoma (26 cases), liver cirrhosis (21 cases), fulminant hepatitis B (12 cases), sclerosing cholangitis (4 cases) and other terminal liver diseases (7 cases). Lamivudine was used in twelve patients suffering from fulminant hepatitis B. Logistic multivariate regression analysis was applied to determine the risk factors predicting liver transplantation outcomes.

RESULTS

Fifty-four patients survived for more than one month, and 16 patients died within 30 days after orthotopic liver transplantation (OLT). The overall hospital survival rate was 77.1%. The hospital survival rates in the Child's A and B patients were 87.5% and 83.3%, respectively. Those rates were superior to those of the Child's C patients (P < 0.05). The outcome of patients with small hepatocellular carcinoma (HCC) was superior to that of patients with large HCC. Preoperative APACE III scores, the severity of ascites and serum creatine level had independent influence on outcome. Of the patients with fulminant HBV infection, 9 recipients survived for a follow-up period of 2 - 24 months. Treatment with lamivudine monotherapy was both well tolerated and efficacious in patients with fulminant hepatitis B.

CONCLUSIONS

The results indicate that orthotopic liver transplantation could provide long-term cure and palliation for patients with HCC, and that patient selection is extremely important in predicting outcome. The results support the continued application of liver transplantation as a therapeutic modality for various end-stage liver diseases and that lamivudine is an effective and safe monotherapy in OLT for patients with HBV infection.

High hepatitis B virus (HBV) DNA viral load as the most important risk factor for HBV reactivation in patients positive for HBV surface antigen undergoing autologous hematopoietic cell transplantation

The risk factors for hepatitis due to hepatitis B virus (HBV) reactivation in patients positive for hepatitis B surface antigen (HBsAg) treated with autologous hematopoietic cell transplantation (HCT) are unknown. We evaluated 137 consecutive patients (23 positive for HBsAg, 37 positive for hepatitis B surface antibody, and 77 negative for HBV) who underwent HCT. Serial serum ALT were measured before transplant and after transplant at 1 to 4 weekly intervals for the first year and then at 2 to 12 weekly intervals thereafter. Before HCT, basic core promoter (T(1762)/A(1764)) and precore (A(1896)) HBV variants were determined in HBsAg-positive and HBV DNA-positive (by polymerase chain reaction assay) patients by direct sequencing and serum HBV DNA quantitation using the Digene Hybrid Capture II assay. Cox proportional hazards analysis was used to assess the association between pretransplantation HBV virologic and host factors and occurrence of hepatitis due to HBV reactivation. After HCT, hepatitis due to HBV reactivation was more common in HBsAg-positive patients than in HBsAg-negative patients (hazard ratio, 33.3; 95% confidence interval [CI], 7.35-142.86; P <.0001). HBsAg-positive patients with detectable serum HBV DNA before HCT (on Digene assay) had a significantly higher risk of hepatitis due to HBV reactivation than HBsAg-positive patients with no detectable serum HBV DNA (adjusted hazard ratio, 9.35; 95% CI, 1.65-52.6; P =.012). Thus, we found that hepatitis due to HBV reactivation is common in HBsAg-positive patients undergoing autologous HCT. A high HBV DNA level (>10(5) copies/mL) was the most important risk factor for HBV reactivation, and its lowering by administration of nucleoside analogues before transplantation should be considered.

Modelling death rates for carriers of hepatitis B

Hepatitis B carriers who acquired the infection perinatally die from hepatocellular carcinoma (HCC) and cirrhosis at high rates. Published cohort studies are largely limited to males and are too small to estimate the age-specific risk of death. We therefore used routinely collected Hong Kong data to estimate the risks. Deaths were partitioned between carriers and non-carriers, then current life table calculations determined life expectancy and probability of dying from HCC or cirrhosis. HCC is the dominant cause of death for male carriers in middle adulthood with a lifetime risk of 27% for HCC compared to 4% for females. Predicted life expectancy is 72 years for male carriers, compared to 79 years for non-carriers. Female carriers have a life expectancy of 81 years and non-carriers 83 years. This model probably applies to all southern Chinese populations and emigrants with similar life history, and other populations that acquired infection early in life.

Disease recurrence after liver transplantation in Western Australia

BACKGROUND AND AIM

Orthotopic liver transplantation (OLT) is now the accepted therapy for end-stage chronic liver disease. Long-term survival is now expected in the majority of patients and, consequently, disease recurrence has emerged as a major concern. Our aim was to document the rate of disease recurrence after liver transplantation for conditions other than hepatitis C, in patients followed up by the Western Australian Liver Transplant Service (WALTS).

METHODS

The case notes of all post-OLT patients followed up by WALTS were reviewed. Patients were excluded if survival was less than 3 months post-OLT; OLT was performed for hepatitis C alone or follow up was unavailable. Detection and definition of disease recurrence depended on pretransplant diagnosis, and were based on patient interview, biochemical, immunological and serological tests. Radiological and histological confirmation were obtained where clinically indicated.

RESULTS

Eighty-seven patients were identified (89 OLTs performed). The overall rate of recurrence was 10%. Recurrence rates by disease were: primary sclerosing cholangitis (17%), primary biliary cirrhosis (12%), autoimmune hepatitis (17%), hepatitis B (40%) and alcoholic liver disease (4%). Alcohol use relapse after transplantation occurred in 25%. The overall survival post-OLT was 87%, with a mean follow up of 53 months. Survival in patients with recurrent disease was 89%.

CONCLUSIONS

Disease recurrence after OLT does occur, but overall, it is relatively uncommon. Recurrence rates vary significantly and depend, in part, on indication for OLT. With medium-term follow up, recurrent disease does not have an effect on mortality.

Lamivudine treatment for hepatitis B reactivation in HBsAg carriers after organ transplantation: a 4-year experience

BACKGROUND

Reactivation of hepatitis B after organ transplantation in hepatitis B surface antigen (HBsAg) carriers may be fatal. In this study, we reported our experience of lamivudine treatment in HBsAg carriers who had post-transplant reactivation of hepatitis B.

METHODS

The patients were 15 men and one woman. Nine received kidney transplants, six received heart transplants, and one received a lung transplant. They developed a reactivation of hepatitis B 1-101 months (median, 14 months) after transplantation. They received lamivudine 100 mg daily on a compassionate-use basis, and had regular follow ups. The median pretreatment total serum bilirubin level was 3.0 mg/dL, and the alanine aminotransferase level was 357 U/L. Four of the 16 patients were positive for HBeAg. The serum hepatitis B virus (HBV) DNA levels were > 3000 pg/mL in 13 (81%) patients. Three were coinfected with hepatitis C virus.

RESULTS

The overall survival rate was 75%. All four fatal cases had a pretreatment total serum bilirubin level of > or = 3 mg/dL. Serum HBV-DNA soon became undetectable in 12 survivors. Of the 12 survivors, after a median treatment period of 101 weeks, a lamivudine-resistant strain with variation in the YMDD motif of the HBV polymerase gene developed in three (25%). None had significant adverse reactions to lamivudine treatment.

CONCLUSIONS

These results indicated that lamivudine is effective in the treatment of post-transplant hepatitis B reactivation, including patients with dual chronic hepatitis B and C. Early recognition of HBV reactivation and prompt lamivudine treatment are important to prevent mortality.

Liver transplantation in patients with hepatitis B virus infection: outcome in Asian versus white patients

Previous studies have found that Asian patients transplanted for hepatitis B virus (HBV) infection had worse outcomes than white patients. The aim of this study was to compare outcomes in Asian and white patients listed for liver transplantation for HBV infection. Data of all patients with HBV infection listed for liver transplantation between January 1996 and June 1998 from 20 centers in North America were collected using a survey. Total patients enrolled were 325 (171 whites, 126 Asians, 28 other races). There was no difference in demographics, liver biochemistry, and HBV replicative status between Asians and whites at the time of listing. More Asians had hepatocellular carcinoma and fewer Asians had hepatitis C or D virus coinfection. At the time of this survey, 70 Asians (55%) and 99 whites (58%) had been transplanted. Actuarial 2-year survival posttransplantation for Asians (88%) and whites (92%) was similar. Recurrent HBV infection occurred in 8 (11%) Asians and 12 (12%) whites. Five patients with recurrent HBV infection died, 4 of whom were Asian. Actuarial 2-year survival for Asians versus whites with recurrent HBV infection was 60% versus 90% (P =.04). In this large cohort of patients, overall survival and recurrent HBV infection posttransplantation were comparable between Asians and whites. However, Asians with recurrent HBV infection posttransplantation had significantly higher mortality.

Risks associated with hepatitis A and hepatitis B in patients with hepatitis C

Individuals with hepatitis C virus (HCV) are at risk for acquiring hepatitis A virus (HAV) or hepatitis B virus (HBV) because of shared risk factors. A number of organizations recommend vaccination against HAV and HBV for patients with HCV. The rationale for vaccinating these patients is to prevent hepatic superinfections. Acute HAV superinfection causes more severe disease, acute hepatic failure, and higher fatality rates in patients with underlying chronic liver disease, specifically chronic HBV infection and chronic HCV infection. Available data, although limited, suggest that HBV coinfection with HAV and HCV causes more severe hepatic injury than infection with HAV or HCV alone. At standard doses, hepatitis A and hepatitis B vaccines are safe and immunogenic in patients with mild-to-moderate hepatitis C or chronic liver disease. Regardless of disease severity, vaccination should be routinely administered to patients upon diagnosis of HCV infection. Early vaccination is important because response to vaccination is reduced as liver disease progresses. Prevaccination and postvaccination serology testing is recommended in specific populations. A new combination hepatitis A and hepatitis B vaccine has been shown to be as safe and effective as monovalent hepatitis A and B vaccines and is currently under review by the United States Food and Drug Administration. A combination vaccine would offer ease of administration and convenience and could increase compliance in patients with hepatitis C or other chronic liver disease: two groups that should be more aggressively targeted by healthcare professionals.

Trends of hepatitis B and hepatitis C mortality in Canada, 1979-1997

Mortality data from Statistics Canada were analyzed to measure the temporal trends and burden of illness attributed to viral hepatitis in Canada. Analysis of age-standardized mortality rates from 1979 to 1997 showed an increasing trend in mortality for both hepatitis B and non-A, non-B hepatitis (NANBH), most of which are attributed to hepatitis C infections. Hepatitis B and NANBH age-standardized mortality rates increased respectively, from 0.03 and 0.12 deaths per 100,000 population in 1979 to 0.26 and 0.41 deaths per 100,000 in 1997. Male mortality rates were consistently higher than female for both diseases. Among deaths from chronic liver disease, over 1,000 deaths were estimated to have been caused by hepatitis B and hepatitis C annually. Although the hepatitis B or NANBH recorded deaths largely underestimate the true burden of HBV and HCV in Canada, the temporal trends are useful as they reflect changes in the impact of both diseases.

Vaccines for the developing world: current status and future directions

Developing country infectious disease problems differ substantially from those in the industrialized world, and a major effort must be made to devote necessary resources to development of vaccines for the bulk of human infectious disease suffering. At the same time, the political will must be mobilized, at international and national levels, to obtain the financial support and backing to provide these vaccines for children. Finally, efforts must be made to take advantage of new technologies now being developed which address many of the logistic and programmatic challenges faced by developing country immunization programme delivery systems.

Evidence of serious graft damage induced by de novo hepatitis B virus infection after liver transplantation

De novo hepatitis B virus (HBV) infection after orthotopic liver transplantation (OLT) is commonly believed to be a relatively benign condition, in contrast to post-OLT infection recurrence, considered a very aggressive complication. We reviewed the charts of 569 non-HBV-related OLTs performed at our institution and identified 19 patients (3%) with de novo HBV infection (appearance of hepatitis B surface antigen [HBsAg] after OLT). After a median follow-up of 25 months beyond the detection of HBsAg, 12 patients (63%) had developed serious HBV-related graft damage (cirrhosis in 6 patients, bridging chronic hepatitis in 4 patients, and fulminant hepatitis in 2 patients); 7 patients (37%) had lost their grafts; and 4 patients (21%) had died. All graft losses and deaths were related to de novo HBV infection. Similar rates of severe graft damage (62%), graft loss (38%), and death (33%) related to HBV infection were found in a concomitant series of 21 patients with recurrent HBV infection after OLT. Responses to antiviral therapy (interferon or lamivudine) were also similar in the 2 groups of patients. In 12 patients with de novo HBV infection, evidence of past HBV infection (positive serum antibody to hepatitis B core antigen and/or serum or liver tissue HBV DNA) were detected in the donor (7 patients) or recipient (5 patients). No differences were observed in the clinical course after stratification according to the attributed origin of de novo HBV infection. We conclude that de novo HBV infection after OLT is associated with high rates of morbidity and mortality, similar to those described for post-OLT HBV infection recurrence.

De novo hepatitis B after liver transplantation from hepatitis B core antibody-positive donors in an area with high prevalence of anti-HBc positivity in the donor population

Transmission of hepatitis B virus (HBV) infection from donors who are negative for hepatitis B surface antigen (HBsAg-) but positive for antibody to hepatitis B core antigen (anti-HBc+) has been reported. However, previous studies were generally performed in geographic regions with a low prevalence of anti-HBc positivity in the liver donor population. The aims of this study are (1) to assess the risk for de novo hepatitis B in recipients of livers from anti-HBc+ donors in an area of high prevalence of anti-HBc positivity in the donor population, and (2) to analyze the risk factors for acquisition of HBV infection from anti-HBc+ donors. The transplantation experience of a single center between 1995 and 1998 was reviewed. Thirty-three of 268 liver donors (12%) were HBsAg- and anti-HBc+ during the study period. The proportion of anti-HBc+ donors increased with age; it was lowest (3.6%) in donors aged 1 to 20 years and highest (27.1%) in donors aged older than 60 years. Of the 211 HBsAg- recipients with 3 months or more of HBV serological follow-up, 30 received a liver from an anti-HBc+ donor and 181 received a liver from an anti-HBc- donor. Hepatitis B developed in 15 of 30 recipients (50%) of livers from anti-HBc+ donors but in only 3 of 181 recipients (1.7%) of livers from anti-HBc- donors (P < .0001). None of the 4 recipients who were antibody to HBsAg (anti-HBs)+ at the time of transplantation developed HBV infection after receiving a liver from an anti-HBc+ donor compared with 15 of 26 recipients (58%) who were anti-HBs- (P =.10). None of the 5 anti-HBc+ recipients developed hepatitis B compared with 15 of 25 anti-HBc- recipients (60%; P = 0.04). Child-Pugh score was significantly higher in recipients of livers from anti-HBc+ donors who developed HBV infection than in those who did not (9 +/- 2 v 7 +/- 1; P =.03). In our area, testing liver donors for anti-HBc is mandatory, particularly in older donors. With such information available, anti-HBc+ donors can be safely directed to appropriate recipients, mainly those with anti-HBs and/or anti-HBc at the time of transplantation. In the current era of donor shortage, this policy would allow adequate use of such donors.

Carcinosarcoma of ovary associated with previous radiotherapy

Carcinosarcoma is a rare neoplasm which, in the female genital tract, arises mainly in the endometrium. Although the pathogenesis remains obscure, there is an apparent association between pelvic irradiation and uterine sarcomas. There have been sporadic case reports of the development of carcinosarcomas of the cervix, vagina, and extragenital areas, but not of the ovary, after previous pelvic irradiation. We describe a case of ovarian carcinosarcoma arising in a 74-year-old female who had pelvic irradiation 33 years previously. Exploratory laparotomy showed a 25 x 18 x 9 cm left ovarian tumor with adjacent organ invasion including peri-uterine serosa and rectum. The patient was treated by optimal cytoreduction, followed by chemotherapy with adriamycin and cisplatin. However, acute hepatitis caused by reactivation of hepatitis B virus infection developed just before the fifth course of chemotherapy. She died of hepatic failure two weeks later.

A severe and explosive outbreak of hepatitis B in a rural population in Sirsa district, Haryana, India: unnecessary therapeutic injections were a major risk factor

Most outbreaks of viral hepatitis in India are caused by hepatitis E. This report describes an outbreak of hepatitis B in a rural population in Haryana state in 1997. At least 54 cases of jaundice occurred in Dhottar village (population 3096) during a period of 8 months; 18 (33.3%) of them died. Virtually all fatal cases were adults and tested positive for HBsAg (other markers not done). About 88% (21/24) of surviving cases had acute or persistent HBV/HCV infections; 54% (13/24) had acute hepatitis B. Many other villages reported sporadic cases and deaths. Data were pooled from these villages for analysis of risk factors. Acute hepatitis B cases had received injections before illness more frequently (11/19) than those found negative for acute or persistent HBV/HCV infections (3/17) (P = 0.01). Although a few cases had other risk factors, these were equally prevalent in two groups. The results linked the outbreak to the use of unnecessary therapeutic injections.

Hepatitis virus infections in heart transplant recipients: epidemiology, natural history, characteristics, and impact on survival

BACKGROUND & AIMS

We have observed a high prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection in heart transplant recipients (HTRs). The aim of this study was to assess the epidemiology, natural history, and clinical and biological characteristics of viral hepatitis in HTRs.

METHODS

From 1983 to 1992, 874 patients underwent heart transplantation at the Pitié-Salpêtrière Hospital, Paris, France, 459 of whom qualified for analysis. A total of 140 patients had posttransplantation hepatitis B, C, or non-A-E. Sixty-nine patients developed HBV infection, 49 HCV infection, 11 HBV-HCV coinfection, and 11 non-A-E hepatitis.

RESULTS

HBV was transmitted nosocomially from patient to patient, most likely during endomyocardial biopsies. HCV was mainly transmitted through blood transfusions or the transplanted organ. Clinical and biological findings after 2 years of follow-up showed that 3 patients with an HBV genotype A precore mutant had severe or subfulminant hepatitis and that patients with HBV and HCV infection always progressed to chronicity. In general, patients had mild alanine aminotransferase level increases, a high level of viral replication, and few severe histologic lesions, except for patients infected by precore HBV mutants. Patients coinfected by HBV and HCV tended to have more severe liver lesions. The survival rate 5 years after transplantation in patients with viral hepatitis (HBV, 81%; HCV, 89%; HBV and HCV coinfection, 100%; non-A-E hepatitis, 73%) was similar to that in patients without liver test abnormalities (76%). The actuarial survival curve was also similar in patients with or without liver test abnormalities.

CONCLUSIONS

In our experience, histologic liver lesions do not progress rapidly in patients with post-heart transplant infection caused by HBV or HCV. HBV or HCV infection seems to have little impact on the 5-year survival rate of HTRs.
