Liver transplantation for haemophiliacs with hepatitis C cirrhosis

The Liver That Cured Christmas: Case Report of Orthotopic Liver Transplant in a Patient with Hemophilia B

Herein, we discuss a case of a 39-year-old male with hemophilia B, who developed end-stage liver disease secondary to nonalcoholic steatohepatitis, that underwent orthotopic liver transplantation (OLT) as a curative means for his liver disease and coagulation disorder. Existing case reports have demonstrated favorable outcomes in patients outside of the United States who received continuous infusions of recombinant factor IX replacement in the perioperative setting after liver transplant. Given limitations in the stability of the recombinant factor IX products in the United States, a dosing strategy was comprised of once daily bolus dosing to achieve satisfactory factor IX levels. Within 48 hours of initial surgery, the patient had sustained factor IX levels above 70% of normal and the patient required no further dosing of factor IX products to date. This strategy helped facilitate less frequent dosing as well as achieved targeted factor levels while synthetic function of the transplanted liver recovered.

Outcome of liver transplantation in patients with hereditary bleeding disorders: a single centre UK experience

INTRODUCTION

Patients with hereditary bleeding disorders who have developed end-stage liver disease as a consequence of hepatitis C infection (HCV) acquired from factor concentrates prior to the introduction of viral inactivation continue to be referred for liver transplantation.

METHODS

A retrospective review of case notes and electronic records was performed on all patients with bleeding disorders who have undergone liver transplantation at the University Hospital Birmingham (UHB).

RESULTS

Between 1990 and 2014, 35 liver transplants have been performed in 33 patients with hereditary bleeding disorders. The indication for transplantation was mainly end-stage liver disease secondary to HCV. Five patients had human immunodeficiency virus (HIV) co-infection. No excess mortality due to bleeding occurred in the peri or postoperative period. Median overall survival post transplant is 9.7 years. Overall survival rates at 1, 3 and 5 years are 90%, 72% and 64% respectively. The predominant cause of mortality was liver failure secondary to either recurrent HCV or recurrent hepatocellular carcinoma (HCC). The median overall survival in patients with HIV co-infection is shorter than in those with mono-infection but this is not statistically significant. Patients with a pre-existing HCC had a statistically significant shorter survival (2.4 years vs. 13.6 years, P = 0.007).

CONCLUSION

Liver transplantation has become an accepted treatment option for patients with hereditary bleeding disorders and HCV associated end-stage liver disease with survival rates similar to non-bleeding disorder patients.

Relevance of ADAMTS13 to liver transplantation and surgery

A disintegrin-like and metalloproteinase with thrombospondin type-1 motifs 13 (ADAMTS13) specifically cleaves unusually-large von Willebrand factor (VWF) multimers under high shear stress, and down-regulates VWF function to form platelet thrombi. Deficiency of plasma ADAMTS13 activity induces a life-threatening systemic disease, termed thrombotic microangiopathy (TMA) including thrombotic thrombocytopenic purpura (TTP). Children with advanced biliary cirrhosis due to congenital biliary atresia sometimes showed pathological features of TMA, with a concomitant decrease of plasma ADAMTS13 activity. Disappearance of their clinical findings of TTP after successful liver transplantation suggested that the liver is a major organ producing plasma ADAMTS13. In situ hybridization analysis showed that ADAMTS13 was produced by hepatic stellate cells. Subsequently, it was found that ADADTS13 was not merely responsible to development of TMA and TTP, but also related to some kinds of liver dysfunction after liver transplantation. Ischemia-reperfusion injury and acute rejection in liver transplant recipients were often associated with marked decrease of ADAMTS13 and concomitant formation of unusually large VWF multimers without findings of TMA/TTP. The similar phenomenon was observed also in patients who underwent hepatectomy for liver tumors. Imbalance between ADAMTS13 and VWF in the hepatic sinusoid might cause liver damage due to microcirculatory disturbance. It can be called as “local TTP like mechanism” which plays a crucial role in liver dysfunction after liver transplantation and surgery.

Living donor liver transplantation from an asymptomatic donor with mild coagulation factor IX deficiency: report of a case

The use of donors with coagulation FIX deficiency is controversial, and there are no current protocols for peri-transplant management. We herein describe the first reported case of a pediatric LDLT from an asymptomatic donor with mild coagulation FIX deficiency. A 32-yr-old female was evaluated as a donor for her 12-month-old daughter with biliary atresia. The donor's pretransplant coagulation tests revealed asymptomatic mild coagulation FIX deficiency (FIX activity 60.8%). Freeze-dried human blood coagulation FIX concentrate was administered before the dissection of the liver and 12 h afterwards by bolus infusion (40 U/kg) and was continued on POD 1. The bleeding volume at LDLT was 590 mL. On POD 1, 3, 5, and 13, the coagulation FIX activity of the donor was 121.3%, 130.6%, 114.6%, and 50.2%, respectively. The donor's post-transplant course was uneventful, and the recipient is currently doing well at 18 months after LDLT. The FIX activity of the donor and recipient at nine months after LDLT was 39.2% and 58.0%, respectively. LDLT from donors with mild coagulation FIX deficiency could be performed effectively and safely using peri-transplant short-term coagulation FIX replacement and long-term monitoring of the plasma FIX level in the donor.

Liver transplantation for a pediatric patient with hemophilia B

Hemophilia exposes patients to greater risks of bleeding complications during the perioperative period. However, there are no current protocols for factor replacement during LT. We herein describe a case of pediatric living donor LDLT performed for a patient with hemophilia B using perioperative short-term factor replacement. A 4-yr-old female patient with an extrahepatic portosystemic shunt and asymptomatic hemophilia B (factor IX activity 18.7%) underwent an ABO-compatible LDLT using a left lobe graft. The bleeding volume was 2980 mL. Freeze-dried human blood coagulation factor IX concentrate (Novact M, Kaketsuken, Japan) was administered at the induction of anesthesia and at the end of LDLT by bolus infusion (80 U/kg) and was continued by bolus infusion (40 U/kg) on POD 1, 2, 3, and 4. On POD 1, 5, 8, and 12, the factor IX plasma levels were 34.5%, 64.9%, 43.5%, and 53.1%, respectively. The postoperative course was uneventful, and the patient is currently doing well at 2.5 yr after LDLT. Factor concentrate should be administered at the induction of anesthesia and at the end of LT by bolus infusion, and thereafter be continued for a few days after LT by bolus infusion.

Outcome of liver transplantation for haemophilia

BACKGROUND

Prior to routine screening of blood products many patients with haemophilia were infected with hepatitis C virus (HCV) and have subsequently gone on to develop end-stage liver disease (ESLD).

PATIENTS AND METHODS

We report our experience of liver transplantation (LT) in patients with haemophilia that developed ESLD secondary to HCV. Patients transplanted from 1994 to 2008 were identified retrospectively. Patient demographics pre-, intra- and post-operative details and outcome were documented.

RESULTS

A total of 3800 LT were performed of which 13 had haemophilia A, 4 haemophilia B and one factor (F)X deficiency. All patients were male with a median age of 52 years (range 26-59), all were HCV antibody positive, 5 (28%) were human immunodeficiency virus (HIV) positive and 4 (22%) had hepatocellular carcinoma. Median intra-operative blood loss was 4.2 l (range 0.8-12) and all received coagulation factor support peri-operatively. Coagulation was unsupported by 72 h post-operatively in all recipients. Two patients developed complications as a result of post-operative bleeding. At a median follow-up of 90 months, 8 patients have died, including 4 of the 5 patients that were HIV positive. The median survival of patients with and without HIV co-infection was 26 and 118 months, respectively.

CONCLUSION

LT in patients with haemophilia cures the coagulation disorder and in the absence of HIV/HCV co-infection is associated with long-term patient survival.

Liver transplant in patients with HIV: infection risk associated with HIV and post-transplant immunosuppression

Before the introduction of highly active antiretroviral therapy, HIV-infected patients who underwent liver transplantation (LT) had poor survival, mainly because of a rapid progression to AIDS and its infectious complications during the post-LT immunosuppression phase. However, in the era of highly active antiretroviral therapy, under some specific and well-determined conditions, LT might be as safe and efficacious in HIV patients as it is in non-HIV-infected patients. End-stage liver failure as caused by hepatitis B virus, cirrhosis, and hepatotoxicity should be considered indications for LT in every transplant center. Because of the almost universal hepatitis C virus reinfection and its accelerated course post-LT, LT in hepatitis C virus-coinfected patients deserves more caution and more extended follow-up before it is accepted as a standard indication for LT in HIV-infected patients.

Efficacy of auxiliary partial orthotopic liver transplantation for cure of hemophilia in a canine hemophilia A model

Metabolic liver disease can be cured by orthotopic liver transplantation. Some successful cases of whole or partial liver transplantation have been reported. Because liver function in these recipients is normal save for the production of the responsive metabolic factor, auxiliary partial orthotopic liver transplantation (APOLT) may produce a benefit. However, no experimental model of APOLT for metabolic liver diseases has been reported. We established a canine APOLT model to evaluate the clinical feasibility and efficacy of APOLT to cure hemophilia. The donor normal beagle dog was used to establish an APOLT model. A left lobe partial liver graft taken from the donor was orthotopically transplanted to the recipient after resection of the native left lobe preserving the native right lobe. Recipients showed no atrophy and comparable blood flow in both the graft and the native liver at the time of exploration after APOLT. Thus, APOLT was performed from a normal donor to a recipient with hemophilia A. In this recipient, blood factor VIII activity markedly increased after APOLT and was maintained for 7 weeks. No episode of bleeding was seen during the observation. In conclusion, a canine APOLT model was successfully established as evidenced by sustained production of factor VIII in a hemophilia recipient. These findings suggest the clinical feasibility and efficacy of APOLT for metabolic liver diseases.

Preclinical experiment of auxiliary partial orthotopic liver transplantation as a curative treatment for hemophilia

The cause of hemophilia is deficiency of coagulation factor VIII production in the liver, which can be cured by liver transplantation. Because the hepatic function of hemophilia patients is quite normal except for production of factor VIII, auxiliary partial orthotopic liver transplantation (APOLT) is beneficial in that patient survival is secured by preserving native liver even in the event of graft loss. However, it is not known whether the graft of APOLT would be enough to cure hemophilia. We evaluated the efficacy and feasibility of APOLT for hemophilia in a canine hemophilia A model that we established. Partial left liver graft was taken from the normal donor (blood factor VIII activity > 60%). The graft was transplanted to the hemophilia beagle dog (blood factor VIII activity < 5%) after resection of the left lobe preserving native right lobe. Changes in time of blood factor VIII activity and liver function parameters were observed after APOLT. APOLT and perioperative hemostatic management were successfully performed. The blood factor VIII activity increased to 30% after APOLT, and was sustained at least 6 weeks throughout the observation period without symptoms of bleeding. The result demonstrated sustained production of factor VIII in the hemophilia recipient after APOLT. Transplantation of approximately one third of whole liver resulted in cure of hemophilia. In conclusion, it is suggested that APOLT would be feasible as a curative treatment of hemophilia A to improve quality of life of the patients.

Review article: current status of liver transplantation in HIV-infected patients

The increases in survival of patients infected with human immunodeficiency virus is attributed to the introduction of combination human immunodeficiency virus antiviral therapy, better known as highly active anti-retroviral therapy. In fact, survival statistics have improved such that individuals often succumb to other disease entities, notably liver failure and not from acquired immunodeficiency syndrome complications. Liver transplantation has been introduction in this patient population in several centres around the world. This review will discuss the current clinical status of liver transplantation in individuals suffering from human immunodeficiency virus infection.

Liver transplantation in patients with HIV infection

1. Liver transplantation for human immunodeficiency virus (HIV)-positive patients with end-stage liver disease in the era of highly active retroviral therapy has proven to be an effective treatment. The concerns of HIV progression have not been borne out by the growing worldwide experience. 2. CD4 counts are stable and HIV viral load is controllable with medication following liver transplantation. 3. Hepatitis C virus (HCV) coinfection in HIV-positive recipients is universal, but the severity of recurrence does not appear to be different from that in HIV-negative patients with HCV liver disease. 4. Complex pharmacokinetic interactions between the calcineurin inhibitors used for immunosuppression along with protease inhibitors are present, but management directed at recognizing the need for monitoring levels does not appear to increase the risk of toxicity. 5. The degree of immunosuppression from iatrogenic drug therapy and HIV does not lead to increased risk of infectious complications.

Solid organ transplantation in HIV-infected recipients

HIV is generally regarded as an acceptable reason to exclude a potential recipient from consideration for transplantation. Most of the data in the literature regarding transplantation of HIV sero-positive individuals pertains to the time prior to the administration of Highly Active Anti-Retroviral Therapy (pre-HAART). This data, therefore, provides little guidance for the management of HIV-positive individuals in the current era. The development of HAART has resulted in a decreased mortality. With prolonged survival more HIV-infected individual are developing end stage organ disease from co-existing conditions such as HCV and HBV, and diseases common in the general population such as diabetes mellitus and hypertension. This has lead to clinicians, researchers and patients to actively investigate the role of solid organ transplantation in HIV-infected individuals. In this article We review the literature to date in liver and renal transplantation, including more recent data in patients receiving HAART.

Kidney and liver transplantation in human immunodeficiency virus-infected patients: a pilot safety and efficacy study

BACKGROUND

Human immunodeficiency virus (HIV)-infected patients have historically been excluded from consideration for transplantation out of concern for the effects of immunosuppression on the progression of HIV disease. Improvements in HIV-related morbidity and mortality with the use of highly active antiretroviral therapy (HAART) have prompted a reevaluation of transplantation as a treatment option for HIV-infected patients with end-stage kidney and liver disease.

METHODS

Eligible patients met standard transplant criteria. They had undetectable plasma HIV-1 RNA levels (viral load) for 3 months (kidney) or were predicted to achieve viral load suppression posttransplantation if unable to tolerate HAART (liver); a CD4+ T-cell count of more than 200 cells/microL (kidney) or more than 100 cells/microL (liver) for 6 months; and no history of opportunistic infections and neoplasm. Standard immunosuppression included prednisone, mycophenolate mofetil (CellCept, Roche Pharmaceuticals, Basel, Switzerland), and cyclosporine (Neoral, Novartis, East Hanover, NJ).

RESULTS

Fourteen patients received transplants (10 kidney transplants, mean follow-up 480 days; four liver transplants, mean follow-up 380 days). All of the kidney transplant recipients (100%) are alive and with functioning grafts, and three of four liver transplant patients (75%) are alive and well with functioning grafts (all liver transplant patients with normal liver function tests). The one death occurred 445 days posttransplantation in a liver recipient coinfected with hepatitis C virus, who died as the result of its rapid reoccurrence. Rejection occurred in 5 of 10 kidney transplant recipients but did not occur in any of the four liver transplant recipients. HIV viral loads have remained undetectable in all patients maintained with HAART. CD4 counts have remained stable in patients not treated for rejection. Patients receiving protease inhibitors require 25% of the dose of cyclosporine compared with patients receiving nonnucleoside reverse transcriptase inhibitors.

CONCLUSIONS

There has been no evidence of significant HIV progression and no adverse effect of HIV on allograft function. Rejection is a concern in kidney transplant recipients, as is the possible poor outcome in hepatitis C virus-coinfected liver transplant recipients. Preliminary data are encouraging and indicate that transplantation should be a treatment option for individuals with well-controlled HIV disease.

Treatment of a patient with hemophilia A and hepatitis C virus-related cirrhosis by living-related liver transplantation from an obligate carrier donor

BACKGROUND

Decompensated hepatitis C virus (HCV)-related cirrhosis is the main indication for liver transplantation. We report the first successful living-related liver transplantation in a 49-year-old hemophilia A patient with end-stage HCV-related cirrhosis using a graft obtained from his 20-year-old daughter, an obligate carrier.

METHODS

The donor's autologous fresh-frozen plasma rich in factor VIII (FVIII) by treatment with 1-deamino-8-D-arginine vasopressin was prepared before the operation. At induction, 1-deamino-8-D-arginine vasopressin was given to the donor to increase plasma FVIII level. In addition, autologous fresh-frozen plasma containing high FVIII concentrate was infused intraoperatively. The right lobe was harvested from the donor and transplanted orthotopically. The recipient was treated postoperatively with recombinant FVIII and immunosuppressive agents.

RESULTS

The donor did not receive recombinant FVIII or allogenic blood during perioperative periods. No bleeding was encountered in the donor perioperatively. The recipient showed a steady increase in FVIII activity postoperatively and was discharged 40 days after transplantation. Ribavirin and interferon-alpha were provided for 3 months postoperatively to prevent potential recurrence of HCV infection. Serum HCV-RNA by RT-PCR became negative after such treatment.

CONCLUSIONS

End-stage liver disease in patients with hemophilia A can be an indication for living-related liver transplantation. Furthermore, a graft from a living-related donor with hemophilia A carrier seems to be suitable provided such individuals receive adequate support for coagulopathies.

Liver transplantation in haemophilia

We report our UK single-centre experience of liver transplantation in haemophilia patients with chronic hepatitis C (HCV) infection. Between March 1990 and March 2001, 16 patients were referred for transplant assessment and 11 (mean age 46 years: nine haemophilia A, two haemophilia B) have been transplanted. Factor concentrate replacement was administered using a continuous infusion regimen following initial bolus dosing. Concentrate infusion was discontinued at a median of 36 h (range 24-72 h) post transplant. Nine patients remain alive at a median of 5 years post transplant (6 months to 11 years). One patient died 6 years post transplant from myocardial infarction. The other patient died of liver failure as a consequence of HCV infection 3 months following a second transplant, having developed HCV cirrhosis within 1 year of receiving his initial graft. Five of the seven patients who have had annual liver biopsy surveillance have developed histological changes of HCV hepatitis at a median of 3 years post transplant (1 year to 9 years). One of these patients progressed to cirrhosis at 3 years 5 months post transplant. Two patients have shown no evidence of HCV hepatitis at 2 years 8 months and 9 years post transplant respectively. The outcome of liver transplantation in haemophilic patients is good and is associated with relatively little morbidity.

[Liver transplantation in a patient with hemophilia A and end stage liver failure]

We report the case of a 50 year-old man factor VIII deficient haemophiliac and hepatitis C cirrhosis. The patient underwent orthotopic liver transplantation because of episodes of variceal bleeding and encephalopathy. He received factor VIII replacement therapy perioperatively. Factor VIII returned to normal within 24 hours postoperatively and factor VIII replacement was stopped. Liver transplantation can be considered as definitive therapy for haemophilia.

Orthotopic liver transplantation for hepatitis C infection: the best Christmas present?

We report the case of a 60-year-old man with mild Christmas disease, Factor IX 10% of normal, who developed chronic hepatitis C infection after receiving coagulation factor concentrates. Subsequently he developed encephalopathy and liver failure and was referred for liver transplantation. Following transplantation, Factor IX levels rapidly normalised and have remained so, representing a phenotypic cure of his Christmas disease.

Therapy for chronic hepatitis B and C infection in haemophilia

Haemophiliacs, until recently, have been at risk of hepatitis B and C infection. Substantial numbers of patients remain persistently infected. Several lines of evidence suggest that these diseases will cause considerable morbidity unless therapy can successfully reduce viraemia and prevent disease progression. Cessation of viral replication may prevent progression to hepatic fibrosis.

Outcome of orthotopic liver transplantation in patients with haemophilia

BACKGROUND

Many patients with haemophilia have developed cirrhosis or hepatocellular carcinoma due to transfusion acquired chronic viral hepatitis.

AIMS

To assess the long term outcome of all haemophilic patients reported to have undergone orthotopic liver transplantation.

METHODS

Transplant centres of patients identified by medical database search were contacted and survival data assessed by Kaplan-Meier analysis.

RESULTS

Twenty six haemophilic men (median age 46 years, range 5-63 years) underwent orthotopic liver transplantation in 16 centres between 1982 and 1996. Indications for transplantation were hepatitis C cirrhosis (69%), hepatitis B with or without C cirrhosis (15%), viral hepatitis related hepatocellular carcinoma (12%), and biliary atresia (4%). Six patients (23%) were infected with human immunodeficiency virus (HIV). Postoperatively, the median time to normal clotting factor levels was 24 hours (range 0-48 hours) and exogenous clotting factors were stopped at a median of 24 hours (range 0-480 hours). Four patients (15%) had bleeding complications. The one and three year survival of HIV positive recipients (67% and 23%) was significantly poorer (p = 0.0003) than that of HIV negative recipients (90% and 83%). Coagulopathy was cured in all patients surviving more than 12 days post-transplant. Six of the 20 patients (30%) with hepatitis C cirrhosis pretransplant had evidence of disease recurrence at a mean of nine months post-transplant.

CONCLUSIONS

Hepatitis C cirrhosis is the most common indication for orthotopic liver transplantation in patients with haemophilia. Transplantation results in long term cure of haemophilia but may be complicated by the effects of HIV infection or recurrent viral hepatitis.

Current Practice in the Treatment of Haemophilia

Haematologists are long standing proponents of evidence based practice-well exemplified among professionals who care for patients with haemophilia. The rapidly expanding range of therapeutic products and the numerous accompanying clinical trials are swiftly interpreted and translated into clinical practice. This translation is formalised by frequently updated quidelines issued by the United Kingdom Haemophilia Centre Directors' Organisation (UKHCDO) and relevant to all doctors involved in the care of patients with haemophilia. In the last five years eight sets of guidelines have been issued in the UK alone relating to the treatment of haemophilia and its complications [1-8]. Against this background we aim to review current practice in the treatment of haemophilia.
