Liver transplantation is a treatment available for many patients with liver cirrhosis who find in this treatment a way to improve life expectancy and quality of life. Paranoid schizophrenia affects 1% of the general population, produces psychotic symptoms, and runs a chronic course in some cases with significant deterioration in all areas of life. To discuss the case of a patient with liver cirrhosis diagnosed with paranoid schizophrenia during the evaluation protocol for liver transplantation. Case report. We report the case of a 47-year-old woman with liver cirrhosis whose only alternative to improve life expectancy and quality of life was access to liver transplantation. During routine evaluations the liaison psychiatrist observed first-order psychotic symptoms and documented a life story that confirmed the presence of paranoid schizophrenia. Paranoid schizophrenia is a psychiatric disorder common in the general population that can be a part of the medical comorbidities of patients requiring liver transplantation and is not an absolute contraindication to its completion. We are unaware of similar cases of liver transplantation in patients with schizophrenia in our country. We believe this is a big step on the road to overcome the stigma that mental illness imposes on patients. Copyright © 2012 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

A liver from a donor with brain death due to a ruptured cerebral aneurysm was transplanted. The liver had multiple bilobar simple cysts; the largest was less than 3 cm in diameter. The noncystic liver volume was greater than 50%, and the liver had neither fibrosis nor venous congestion. The donor surgery was performed in accordance with the standard protocol without rupture of the cysts. The recipient was a 40-year-old man with cirrhosis associated with hepatitis B. The recipient operation was done by using the piggyback method with no complications. Excessive drainage of chylous ascites (10 000 mL/d) started in the first days after surgery and continued, gradually decreasing until the end of the second month. The patient was discharged with no complications at the end of the third month. No growth in the cysts was observed on follow-up computed tomography scans. Excluding this particular case, a total of 7 other patients have received a polycystic liver transplant. In all 7 cases, the fact that the donor had polycystic liver disease was not known but was encountered by coincidence during procurement. The case reported here is the first case where the polycystic liver disease was diagnosed before procurement and the transplant was still carried out. It appears that, if the donor liver has enough healthy noncystic volume, polycystic livers can be transplanted.

In liver haemangiomas, the risk of complication rises with increasing size, and treatment can be obligatory. Here we present a case of a 46-year-old female who suffered from a giant haemangioma causing severe portal hypertension and vena cava compression, leading to therapy refractory ascites, hyponatremia and venostasis-associated thrombosis with pulmonary embolism. The patients did not experience tumour rupture or consumptive coagulopathy. Surgical resection was impossible because of steatosis of the non-affected liver. Orthotopic liver transplantation was identified as the only treatment option. The patient's renal function remained stable even though progressive morbidity and organ allocation were improbable according to the patient's lab model for end-stage liver disease (labMELD) score. Therefore, non-standard exception status was approved by the European organ allocation network "Eurotransplant". The patient underwent successful orthotopic liver transplantation 16 mo after admission to our centre. Our case report indicates the underrepresentation of morbidity associated with refractory ascites in the labMELD-based transplant allocation system, and it indicates the necessity of promptly applying for non-standard exception status to enable transplantation in patients with a severe clinical condition but low labMELD score. Our case highlights the fact that liver transplantation should be considered early in patients with non-resectable, symptomatic benign liver tumours.

Liver transplantation is especially challenging in patients who are Jehovah's Witnesses because their religious beliefs prohibit the receipt of blood products. We present two cases of living donor liver transplantation performed in adult Jehovah's Witnesses in South Korea without the use of blood products. In the first case, preoperative erythropoiesisstimulation therapy increased hemoglobin levels from 8.1 to 13.1 g/dl after 9 weeks. In the second case, hemoglobin levels increased from 7.4 to 10.8 g/dl after 6 months of erythropoiesis-stimulation therapy. With the combination of acute normovolemic hemodilution, intraoperative cell salvage, and use of transfusion alternatives, liver transplantation was successfully performed without transfusion of blood products.

The occurrence of de novo malignant neoplasias has been shown in postransplant patients under imunosuppression. It is the second leading cause of late death in liver transplant recipients. The greatest incidence is seen in cancers associated with chronic infection by human papilloma virus, skin cancers, oropharyngeal, and gastrointestinal (GI) malignancies. GI stromal tumors (GISTs) are the most common mesenchymal tumors of the GI tract. Rare cases are identified outside the GI tract are collectively known as extragastrointestinal stromal tumors (EGISTs). We present an EGIST case in a liver transplantation patient. A 64-year-old man underwent liver transplantation because of cirrhosis (hepatitis B virus and alcoholism) and hepatocellular carcinoma. Histopathologic findings revealed 2 trabecular hepatocellular carcinomas: a 3.5-cm-diameter lesion located at segment VIII and another 2-cm one at segment V. Seven months later, he noticed a hardened, mobile, painless, 3-cm subcutaneous nodule in the perineum localized in the right lateral quadrant 2 cm distant from the anus. A surgical resection with 1 cm margin yielded a histopathology report of a 5.0 x 3.0 cm spindle cell stromal tumor. The immunohistochemical profile was compatible with a GIST, with 5 mitosis per 50 high-powered fields. This tumor is extremely rare after liver transplantation but has shown a good outcome up to now.

The present case report describes the diagnosis and treatment of a patient with veno-occlusive disease (VOD) following liver transplantation. Combining the clinical data and relevant literature, the study aimed to consider the causes of VOD following liver transplantation, and the pathogenesis, clinical diagnosis and auxiliary examination features of VOD. A 42-year-old man who had a long history of taking traditional Chinese medicine (essential components unknown) underwent an orthotropic liver transplantation on January 14, 2011, due to small venous occlusion disease of the liver. The patient was treated with tacrolimus as an antirejection therapy following the surgery, and gradually developed right upper quadrant pain and fatigue. The examination results were consistent with the diagnostic standards for VOD. Following treatment with methylprednisolone, the patient was treated with alprostadil and Danhong injections. Forty days later, the patient's total bilirubin (TBIL) level was observed to have decreased significantly, the liver function had returned to normal and the ascites had decreased, but had not completely disappeared. The patient then underwent a transjugular intrahepatic portosystemic shunt (TIPS) procedure, following which the ascites were shown to have completely disappeared.

Polycystic liver disease is characterized by multiple cystic lesions on the liver. It is an uncommon autosomal dominant disease. The cysts' diameters range from 20 to 30 cm to small microscopic nodules. Generally, more than half of the liver parenchyma is covered. The mass effect of the liver created by the large cysts can cause life-threatening symptoms such as weight loss, reduction of oral intake, and malnutrition. Liver transplantation is the best treatment option in symptomatic patients. We present a patient who had polycystic liver and kidney disease, and we performed liver transplantation because of his life-threatening symptoms. Copyright © 2017 Elsevier Inc. All rights reserved.

Extraction and preservation are of special interest in any liver transplant program. The viability and correct early function of the graft are determinant factors of the success or failure of the transplant. Application of a restrictive criterion in the acceptance of donor livers has allowed us to achieve an optimal viability (96.7%) in our first 60 cases of liver transplant.

Porphyrias are a group of diseases characterized by an enzyme deficiency in the heme biosynthesis pathway, resulting in accumulation of precursor molecules in the tissue. Some porphyric patients develop progressive liver disease that requires liver transplantation. This case report describes special anesthetic challenges, including careful selection of drugs and the use of special filters that can exclude harmful wavelengths of ultraviolet, in a patient with porphyria who underwent living donor liver transplantation. Understanding the patient's status and disease process, and avoiding triggering factors of porphyria attacks, are important for successful liver transplantation anesthesia in patients with porphyria.

Since 1981, when the liver transplantation program was initiated at the University of Pittsburgh, we have been impressed with the prevalence of pancreatitis occurring following liver transplantation in patients transplanted for hepatitis B-related liver disease. To either confirm this clinical impression or refute it, the records of the 27 HbsAg+ patients and those of an additional 24 HbsAg- but HbcAb and/or HbsAb+ patients who underwent orthotopic liver transplantation were reviewed to determine the prevalence of clinical pancreatitis and hyperamylasemia (biochemical pancreatitis) following liver transplantation (OLTx). Post-OLTx hyperamylasemia occurred significantly more frequently in HbsAg+ patients (6/27) than it did in the HbsAg- patients (0/24) (P less than 0.05). More importantly, clinical pancreatitis occurred in 14% (4/27) of the HbsAg+ patients and 0% (0/24) of the HbsAg- patients. Interestingly, in each case, the pancreatitis was associated with the occurrence of acute hepatitis B infection of the allograft. Based upon these data, we conclude that pancreatitis occurring after liver transplantation is more common in patients transplanted for active viral liver disease caused by hepatitis B than in those with inactive viral liver disease. These observations suggest that pancreatitis occurring in, at least some cases following liver transplantation for viral liver disease, may result from hepatitis B virus infection of the pancreas.

Gas gangrene is a rare and devastating infectious process that can occur after liver transplantation, most often following hepatic artery thrombosis. We here report 3 cases of gas gangrene following orthotopic liver transplantation. Blood cultures were positive for Clostridium clostridiiforme in one case. In 2 other cases liver tissue from explanted specimens was positive for Enterobacter cloacae. Ultrasound demonstrated hepatic artery thrombosis and computed tomography imaging revealed diffuse liver necrosis with gas formation in each case. All 3 patients were successfully treated with a combination of antibiotics and emergent re-transplantation. We review previously published cases of gas gangrene after liver transplant and emphasize the importance of hepatic artery thrombosis in the development of this syndrome as well as the frequent involvement of non-clostridial organisms. Early diagnosis and aggressive combined medical and surgical treatment including re-transplantation are essential for successful treatment of these rare and catastrophic infections.

Abstract Nowadays, de novo malignancies have become an important cause of death after transplantation. According to the accumulation of cases with liver transplantation, the incidence of de novo gastric cancer is anticipated to increase among liver transplant recipients in the near future, especially in some East Asian countries where both liver diseases requiring liver transplantation and gastric cancer are major burdens. Unfortunately, there is limited information regarding the relationship between de novo gastric cancer and liver transplantation. Herein, we report a case of stage IIIc gastric cancer after liver transplantation for hepatocellular carcinoma, who was successfully treated by radical distal gastrectomy with D2 lymphadenectomy but died 15 months later due to tumor progression. Furthermore, we extract some lessons to learn from the case and review the literatures. The incidence of de novo gastric cancer following liver transplantations is increasing and higher than the general population. Doctors should be vigilant in early detection and control the risk factors causing de novo gastric cancer after liver transplantation. Curative gastrectomy with D2 lymphadenectomy is still the mainstay of treatment for such patients. Preoperative assessments, strict postoperative monitoring, and managements are mandatory. Limited chemotherapy could be given to the patients with high risk of recurrence. Close surveillance, early detection, and treatment of posttransplant cancers are extremely important and essential to improve the survival. PMID:26886605

We report a case of successfully treated multiple liver abscesses in a liver-transplanted patient, sustained by combined multidrug-resistant infections. Two months after a liver transplant, a computed tomography scan revealed the presence of multiple abscesses in the liver graft. Blood cultures and abscessual liver fluid were both positive for acquired colistin- and carbapenem- resistant Klebsiella pneumoniae and an extended-spectrum of beta-lactamases-producing Enterobacter aerogenes. The treatment strategy consisted of different prolonged antimicrobial combinations and draining of the abscesses with complete recovery of the liver lesions.

Mucormycosis is a rare but potentially lethal complication of liver transplantation. Most reported cases have involved rhinocerebral, pulmonary, gastrointestinal, or disseminated forms. We present herein the case of a 61-year-old male patient with hepatocellular carcinoma who developed isolated penile mucormycosis after orthotopic liver transplantation. Such a case has not been reported in the literature to date. Early diagnosis and timely surgical intervention combined with comprehensive treatment are the key factors for improving the survival rate in patients with mucormycosis.

Introduction Liver transplantation (LT) is the gold standard for decompensated Chronic Liver Disease (CLD) in individuals satisfying the selection criteria. Organ scarcity is the rate limiting step in liver transplantation across the globe. Expanding the donor pool is practiced by transplant surgeons across the globe in view of perennial donor organ scarcity and ever increasing organ demand. Presentation of case We have presented series of 3 cases of liver transplantation (LT) with modified left lobe (conventional right) graft from a situs inversus donor and implanting it as a conventional right lobe with a modified technique. The grafts had Type 1, Type 2 and Type 3 biliary anatomies. One graft had inferior hepatic veins also. All three patients had uneventful recoveries. The follow up period range is 4 years to 8 months. Discussion There are multiple case reports in the literature involving situs inversus donors in liver transplantation. Various techniques have also been described. We describe simple and effective technique which has proved successful to our patients. Conclusion SIT donors can be safely accepted for living donor liver transplantation. It is a technically challenging procedure both for donor liver harvesting and implantation in recipient. This is the first case series of LT using modified left lobe graft (conventional right) from a SIT donor with 2 different techniques. Biliary anastomosis is the tricky part of the operation.

We studied infections in 101 consecutive patients who underwent liver transplantation between July 1984 and September 1985. The mean length of follow-up was 394 days. Eighty-three percent of population had 1 or more episodes of infection and 67% of the population had severe infections. The overall mortality was 26/101 (26%) and 23 of 26 deaths (88%) were associated with infection. Seventy percent of severe infections occurred in the first 2 months after transplantation. The most frequent severe infections were abdominal abscess, bacterial pneumonia, invasive candidiasis, Pneumocystis pneumonia, and symptomatic cytomegalovirus infection. Patients with more than 12 hours of cumulative surgical time had a higher rate of severe infections (P less than 0.001), particularly fungal (P less than 0.001) and bacterial (P less than 0.01) infections. Also, the use of choledocho-jejunostomy was associated with a higher rate of infection in patients who had more than 1 transplant operation (P less than 0.02). No increase in infection was found in patients who received azathioprine, or more than the median number of steroid boluses or "recycles"; but patients who received OKT3 therapy had a higher rate of protozoal infections (P less than 0.05). A result similar to that of our previous studies was a strong relation between the number of severe fungal infections and prolonged courses of antibiotics after transplant operation (P less than 0.001). Pretransplant manifestations of severe liver disease such as ascites, encephalopathy, and gastrointestinal bleeding were not associated with higher rates of infection after transplantation, but high serum levels of ALT were. Patients with lower ratios of T-helper to T-suppressor lymphocytes had more severe viral (P less than 0.02) and fungal (P less than 0.01) infections after transplantation.

We present a case of a 23-year-old female who underwent orthotopic liver transplantation (OLTx) for biliary atresia, 22 years after a failed Kasai operation. Unusually, her postoperative course was complicated by severe acute humoral rejection. In this case report, we discuss her management as well as the role of plasmapheresis in treating allograft dysfunction secondary to acute humoral rejection in liver transplant patients.

Biliary stenosis is a common complication after liver transplantation, and has an incidence rate ranging from 4.7% to 12.5% based on our previous study. Three types of biliary stenosis (anastomotic stenosis, non-anastomotic peripheral stenosis and non-anastomotic central hilar stenosis) have been identified. We report the outcome of two patients with anastomotic stricture after liver transplantation who underwent successful cutting balloon treatment. Case 1 was a 40-year-old male transplanted due to subacute fulminant hepatitis C. Case 2 was a 57-year-old male transplanted due to hepatitis B virus-related end-stage cirrhosis associated with hepatocellular carcinoma. Both patients had similar clinical scenarios: refractory anastomotic stenosis after orthotopic liver transplantation and failure of balloon dilation of the common bile duct to alleviate biliary stricture. PMID:28104994

Liver transplantation has become an established curative treatment in adult patients with acute or chronic end-stage liver diseases. In pediatric cases the number of cadaveric donor livers is not sufficient and to overcome the shortage of appropriate-sized whole liver grafts, technical variants of liver transplantation have been practiced. Reduced-size cadaveric and split cadaveric allografts have become an important therapeutic option, expanding the availability of size-appropriate organs for pediatric recipients with terminal liver disease. The number of pediatric deaths awaiting liver transplantation has been reduced by the introduction of living-related liver transplantation, developed to overcome the shortage of suitable grafts for children. It is important for radiologists to know that children have distinct imaging of liver transplantation that distinguish them from adults. A multidisciplinary pediatric liver transplantation team should be skilled in pediatric conditions and in associated processes, risks and complications. Radiologists should know the common pediatric liver diseases that lead to liver transplantation, the anastomotic techniques and the expected postoperative imaging findings. The aim of this study is to illustrate the role of non-invasive imaging such us ultrasonography, color Doppler ultrasonography, multidetector computed tomography and magnetic resonance imaging in the evaluation of pediatric liver transplantation and in potential liver donors.

Although several studies have identified posttransplant neurologic sequelae in patients with acute liver failure (ALF), the effects of these sequelae on neuropsychologic functioning after transplant is unknown. This study compared neuropsychologic functioning of ALF patients with chronic liver disease patients after liver transplantation. After liver transplantation, seven ALF patients were compared with a matched control group of patients who had been transplanted for chronic liver disease. The patients were matched by gender, age (within 5 years), and time since transplantation (within 2 years). Patients completed a 2-hour battery of tests, which included measures of attention, memory, motor performance, abstract conceptualization, and visuospatial perception. There were no significant differences between the groups on measures of socioeconomic status or education. Significant differences were found on three separate tests: WAIS-III Vocabulary, WAIS-III Similarities, and WMS-III Paired Associate Learning II. Although these tests measure distinct functions (vocabulary knowledge, abstract conceptualization, and delayed verbal recall), they may be influenced by broader verbal functions, such as verbal fluency, conceptualization, and the ability to articulate ideas. When patients were asked what functions had noticeably deteriorated since transplantation, nearly all complained of memory difficulties, and there was no difference between groups. However, more ALF than chronic liver disease (CLD) patients complained of concentration difficulties. The results of this study suggest that ALF patients may experience more neuropsychologic dysfunction after transplant. Further studies are required to expand on these initial observations with the potential to improve patient care and referral to appropriate rehabilitative services.

Excellent outcomes over the last 3 decades have made liver transplantation the treatment of choice for many advanced liver disorders. This success also opened liver transplantation to new indications such as liver tumors and metabolic disorders. The emergence of such new indications for liver transplantation is bringing a new stream of patients along with disease-specific challenges. The cumulative number of liver transplant recipients is peaking, requiring novel systems of health care delivery that meet the needs of this special patient population. This article reviews updates and new development in pediatric liver transplantation. Copyright © 2017 Elsevier Inc. All rights reserved.

Autoimmune hepatitis (AIH) recurs after liver transplantation and significantly impacts graft function and patient survival. In this case report, we present 2 cases of male patients with refractory recurrent AIH after liver transplantation. Each patient lost their first graft due to refractory continuous AIH. We have not noticed a similar refractory course for our female patients with AIH post-transplantation at our center. Based on our single-center experience there appears to be a gender disparity in the aggressive nature of AIH recurrence after transplantation. Despite the aggressive nature of recurrent AIH in both patients, graft loss occurred beyond 3 years for both patients and did not influence the 1- and 3-year patient survival. If these findings are validated, they may have significant impact on post-transplantation immunosuppression management in male patients.

Sirolimus is a powerful immunosuppressive drug initially used in kidney transplant patients but now increasingly employed in recipients of other types of solid organ transplants, such as liver, heart, lung, or pancreas. Sirolimus is indicated for rescue therapy and to reduce the toxic side effects of calcineurin inhibitors. However, its use has been associated with an uncommon but important pulmonary toxicity. Reports have described interstitial pneumonitis, bronchiolitis obliterans, organizing pneumonia, and alveolar proteinosis. We present the case of a liver transplant patient with interstitial pneumonitis associated with sirolimus.

Adult polycystic liver disease (APLD) is a rare disorder of the liver parenchyma, the treatment of which is still controversial. Conservative surgery may have a significant morbidity and is often ineffective in the long run. Liver replacement may be indicated in case of incapacitating hepatomegaly. Patients (one male, five females) undergoing liver transplantation for symptomatic APLD is presented in this study. The particular nature of this series is the fact that successful transplantation was performed in all cases with preservation of the recipient's inferior vena cava and without use of veno-venous bypass despite massive hepatomegaly and previous extensive liver surgery (in three cases). There was minimal morbidity and no mortality. All patients have excellent quality of life with a median follow-up of 41 months (range: 12-58) as testified by a median Karnofsky score of 90% (range: 80-100%).

Portal vein aneurysms are very rare and represent <3% of all venous aneurysms. They can be congenital or acquired. Most patients do not have liver disease at diagnosis. Although uncommon, portal vein aneurysm has been described after liver transplant. We report the case of a six-yr-old girl who presented with an aneurysm of the extrahepatic portal vein after segmental liver transplantation. Because the patient was asymptomatic and owing to its extrahepatic location, this aneurysm has been successfully followed by clinical exam and imaging for four yr.

To date, only limited cases of Diego blood group disparity in liver transplantation have been reported, and no cases with a long-term clinical course have been documented. Herein, we report a case of Diego blood group disparity in liver transplantation with details of long-term follow-up. The recipient was a 47-year-old woman with primary biliary cirrhosis; her 18-year-old daughter was the donor. Both recipient and donor were of blood type O according to the ABO blood group system. Preoperative serological tests showed the presence of antibodies against the Di(a) antigen only in the recipient, and not in the donor. Thus, the Diego phenotype was Di(a+) in the donor and Di(a-) in the recipient. Living-related liver transplantation was performed in July 2009. Immediate graft function was obtained, and no signs of humoral or cellular rejection were observed during the postoperative period. Further, anti-Di(a) antibodies were not detected throughout the postoperative course. The patient is alive and shows no signs of humoral rejection 34 months after liver transplantation. Liver transplantation has been performed successfully in cases of Diego blood group disparity. Copyright © 2013 Elsevier Inc. All rights reserved.

Background. Methylphenidate (MPH) is widely used in treating children with attention-deficit-hyperactivity disorder. Hepatotoxicity is a rare phenomenon; only few cases are described with no liver failure. Case. We report on the case of a 12-year-old boy who received MPH for attention-deficit-hyperactivity disorder. Two months later the patient presented with signs and symptoms of hepatitis and MPH was discontinued, showing progressive worsening and developing liver failure and a liver transplantation was required. Other causes of liver failure were ruled out and the liver biopsy was suggestive of drug toxicity. Discussion. One rare adverse reaction of MPH is hepatotoxicity. The review of the literature shows few cases of liver injury attributed to MPH; all of them recovered after withdrawing the treatment. The probable mechanism of liver injury was MPH direct toxicity to hepatocytes. In order to establish the diagnosis of MPH-induced liver injury, we used CIOMS/RUCAM scale that led to an assessment of “possible” relationship. This report provides the first published case of acute MPH-induced liver failure with successful hepatic transplantation. Conclusions. It is important to know that hepatotoxicity can occur in patients with MPH treatment and monitoring the liver's function is highly recommended. PMID:25688317

Liver transplantation has become the standard treatment for acute failure and end-stage liver disease, but there are fewer donor organs available than patients on the waiting list. The donor pool may be increased by using marginal donor candidates. Some infectious and metabolic diseases have been transmitted to the recipient via marginal donor grafts. Hydatid cyst disease is rarely transmitted to a recipient from the donor graft. A literature search showed only 2 previous cases of liver transplantation using a donor graft that contains a hydatid cyst. We treated a 19-year-old woman who experienced acute on chronic end-stage liver failure secondary to cryptogenic cirrhosis. The liver graft from a 97-year-old marginal cadaveric donor contained a calcified hydatid cyst. No complication was associated with the hydatid cyst at 3 years after transplantation. The present case shows that donor livers with an inactive, calcified hydatid cyst may be used for emergency liver transplantation after considering the location, size, and relation of the cyst to vascular and biliary structures. The cyst may be resected on the back table with a successful treatment outcome.

Primary hyperoxaluria type 1 (PH1) is a rare liver enzymatic defect that causes overproduction of plasma oxalate. Accumulation of oxalate in the kidney and subsequent renal failure are fatal to PH1 patients often in pediatric age. Combined liver and kidney transplantation is the therapy of choice for end-stage renal disease due to PH1. Levels of plasma oxalate remain elevated for several months after liver transplantation, as the residual body oxalate is slowly excreted. Patients with persistent hyperoxaluria after transplant often require hemodialysis, and accumulation of residual oxalate in the kidney can induce graft dysfunction. As the native kidneys are the main target of calcium oxalate accumulation, we postulated that removal of native kidneys could drastically decrease total body oxalate levels after transplantation. Here, we report a case of bilateral nephrectomy at the time of combined liver-kidney transplantation in a pediatric PH1 patient. Bilateral nephrectomy induced a rapid decrease in plasma oxalate to normal levels in less than 20 days, compared to the several months reported in the literature. Our results suggest that removal of native kidneys could be an effective strategy to decrease the need for hemodialysis and the risk of renal dysfunction after combined liver-kidney transplantation in patients with PH1.

BACKGROUND/AIMS—Alcoholic cirrhosis remains a controversial indication for liver transplantation, mainly because of ethical considerations related to the shortage of donor livers. The aim of this study was to review experience to date, focusing on survival rates and complications, and the effect of alcohol relapse on outcome and alterations in marital and socioprofessional status. METHODS—The results for 53 patients transplanted for alcoholic cirrhosis between 1989 and 1994 were compared with those for 48 patients transplanted for non-alcoholic liver disease. The following variables were analysed: survival, rejection, infection, cancer, retransplantation, employment and marital status, alcoholic recurrence. The same variables were compared between alcohol relapsers and non-relapsers. RESULTS—Recovery of employment was the only significantly different variable between alcoholic (30%) and non-alcoholic patients (60%). Two factors influenced survival in the absence of alcohol recidivism: age and abstinence before transplantation. For all other variables, there were no differences between alcoholic and non-alcoholic patients, and, within the alcoholic group, between relapsers and non-relapsers. The recidivism rate was 32%. CONCLUSION—The data indicate that liver transplantation is justified for alcoholic cirrhosis, even in cases of recidivism, which did no affect survival and compliance with the immunosuppressive regimen. These good results should help in educating the general population about alcoholic disease. Keywords: liver; transplantation; alcohol; cirrhosis PMID:10446113

Endogenous Fusarium endophthalmitis is a rare disease predominantly described in immunocompromised patients often due to leukemia. We report a case of bilateral endogenous Fusarium solani endophthalmitis in a liver-transplanted patient. A 56-year-old Danish Caucasian woman who had undergone two liver transplantations, developed endogenous endophthalmitis of her left eye 10 days after the second liver transplantation. Despite continuous therapy, enucleation of her left eye was eventually necessary; at this point funduscopic examination of her right eye disclosed a white inflammatory plaque at the macula consistent with a fungal infection. Microbiological analysis of vitreous fluid from her enucleated left eye revealed Fusarium solani, and light microscopy of her enucleated eye was consistent with Fusarium panophthalmitis with massive ingrowth of the fungi in all areas containing basement membrane collagen. Voriconazole was injected intravitreally in her right eye, and intravenous voriconazole was initiated. No subsequent growth in the inflammatory plaque was observed. She died 6 weeks after the endogenous endophthalmitis was diagnosed. This is the first report of endogenous Fusarium solani endophthalmitis in a liver-transplanted patient. Ophthalmologists and physicians dealing with liver transplantation should be aware of the potential for postoperative endophthalmitis due to rare microorganisms, such as Fusarium solani.

As in other western countries the major challenge of liver transplantation in Germany is to expand the number of liver transplantations in respect to the increasing disparity of qualified patients on the waiting list and the still static availability of brain death donor organs. The problem of death on the waiting list has become overt since the German transplantation law has been installed, which has changed the former center-oriented to a patient-oriented allocation weighting waiting time over medical urgency criteria. The more liberal acceptance of so called marginal cadaveric donor livers will probably impair further improvements in the acute and long-term outcome of liver transplantation. This problem can be partially compensated by the use of novel surgical techniques, such as splitting a donor liver to be transplanted into two adult recipients or, more commonly and safe, into an adult and one child. Another alternative to increase the donor pool is living donor liver transplantation, which was first introduced for pediatric recipients but is now increasingly used in adults. In 2001, a constant number of 757 liver transplantations were performed in Germany, including 12.5 % living donor transplantations. Recently, general guidelines for the selection of patients with end-stage liver disease and acute liver failure have been published by the Bundesärztekammer. Additional developments have contributed to improve the results of liver replacement including individualized immunosuppression strategies and novel treatment options to avoid recurrent viral disease following transplantation.

Diaphragmatic hernias (DH) are an unusual complication after pediatric liver transplantation; however, they have been reported with increased frequency in the past few years. DHs are responsible for nearly half of the small bowel obstructions requiring surgical intervention in this patient population. It has been suggested that the use of a left lobe liver graft, surgical trauma, malnourishment, elevated intra-abdominal pressures, and mTor inhibitors may predispose to development of DH. The use of a segmental graft may increase the recognition of diaphragmatic hernia because the surgically damaged right hemi-diaphragm often remains exposed to underlying viscera, instead of being covered by the right hepatic lobe. Treatment is surgical reduction, with up to 20% of the patients requiring resection of the herniated intestine. Herein we describe a case of DH after left segmental liver transplant in a two- yr-old boy that presented one month post left lobe split liver transplant with abdominal pain, anorexia, and respiratory distress. Just like in the majority of the reported cases, an urgent laparotomy with primary repair was performed. No resection of the herniated segment of intestine was required. For pediatric patients with otherwise unexplained respiratory or gastrointestinal symptoms after a left lateral segment liver transplant, right-sided diaphragmatic hernias should always be high in the differential diagnosis.

Management during their sexual life of patients with a liver transplantation is a more or less common situation depending centers. Based on literature review, a focus on management of recipient women was conducted, from contraception to pregnancy, describing the complications related to the status of transplant recipient, but also those that may be related to immunosuppressive agents. If fertility and access to contraception are only slightly modified by graft, complications related to graft or immunosuppressive drugs can affect the pregnancy. On the maternal side, hypertension and preeclampsia are more common, as well as renal dysfunction, iatrogenic diabetes and bacterial or viral infections, acute rejection and graft loss do not appear to be influenced by pregnancy. The fetus is also exposed to risks such as induced prematurity and IUGR. Pregnancy in recipients of hepatic grafts therefore requires joint follow-up by transplant specialist and perinatologist, which leads in most cases to successful outcome for mother and child.

Clonorchiasis is a cholangiopathy caused by foodborne trematode parasites, also known as liver flukes. Clonorchiasis is endemic in a wide geographical area extending from Eastern Europe to Southeast Asia. Infested hosts may remain asymptomatic for decades and consequently their liver can become available as a graft. To date, 20 liver transplantations with liver fluke-infested grafts have been reported in the literature. All of them occurred in Asian countries. We, here, report the first case to our knowledge in the Western world of living-donor liver transplantation (LDLT) with an Opisthorchis felineus-infested graft, and present a review of the literature. A 6-month-old girl with decompensated secondary biliary cirrhosis underwent an LDLT with a left lateral graft infested with O. felineus. After prompt diagnosis and adequate therapy, both donor and recipient had an uneventful postoperative course and long-term follow-up. Liver grafts infested with liver flukes do not pose a contraindication to liver donation from deceased or living donors, provided that a correct diagnosis and treatment are performed in a timely fashion. © 2015 John Wiley & Sons A/S.

Reuse of liver graft for transplantation is extremely uncommon. We report the 1st case of reuse of liver graft from a recipient who had hepatitis B virus (HBV) infection, 11 years after the 1st transplantation. Our relay liver transplantation challenged conventional thinking because of late reuse of graft in the presence of HBV infection. Moreover, both the 1st and the 2nd donors were of advanced age. The key questions were whether the liver graft could be reused safely, especially in the setting of HBV infection, and technical concerns during organ procurement and implantation. The absence of HBV replication was confirmed with negative hepatitis B surface antigen and undetectable serum HBV DNA in the 2nd donor. Based on our experience in managing HBV infection after liver transplantation, we were confident that the adequately suppressed HBV infection in the donor would not jeopardize graft function and that the graft would be able to withstand another ischemia-perfusion injury to continue to function well in our recipient.

Opioid dependence is an increasing public health problem. One of the complications of intravenous opioid use is hepatitis C virus infection, which, in turn, is one of the most common indications for liver transplantations throughout the world. Therefore, the treatment of opioid dependence in a liver transplant recipient requires special attention in terms of graft function, drug interactions, and patient compliance. Buprenorphine is a semi-synthetic opioid-derived agent with analgesic effects. To prevent buprenorphine abuse, it is combined with the opioid antagonist naloxone. This buprenorphine/naloxone combination is the only drug approved for the treatment of opioid dependence in Turkey. Although the literature includes data about the safe usage of buprenorphine in liver transplantation in animals, there is no such evidence in either case reports or clinical trials for the same in humans. In this article, we present a report of our treatment of 2 opioid-dependent patients with buprenorphine/naloxone after liver transplantation due to hepatitis C virus-induced liver cirrhosis.

Kaposi sarcoma after an organ transplant is rare and infrequently involves internal organs. There are 2 reported cases in the English literature of Kaposi sarcoma originating from the transplant ureter after kidney transplant. We report a case of Kaposi sarcoma that occurred in the native ureter of the liver transplant recipient. Initially, the patient refused any further investigation and management and 2 years subsequent, had to undergo a left radical nephroureterectomy owing to the loss of renal function and distending pain. He recovered very well and no recurrence was detected at 47 months' follow-up. To our knowledge, it is the first report in English. We review the literature on this topic and explore the therapeutic principles and histologic features of this sarcoma.

Background Umbilical metastasis is one of the main characteristic signs of extensive neoplastic disease and is universally referred to as Sister Mary Joseph's nodule. Case presentation A 59-years-old Caucasian female underwent liver transplant for end stage liver disease due to hepatitis C with whole graft from cadaveric donor in 2003. After transplantation the patient developed multiple subcutaneous nodules in the umbilical region and bilateral inguinal lymphadenopathy. The excision biopsy of the umbilical mass showed the features of a poorly differentiated papillary serous cystadenocarcinoma. Computed tomographic scan and transvaginal ultrasonography were unable to demonstrate any primary lesion. Chemotherapy was start and the dosage of the immunosuppressive drugs was reduced. To date the patient is doing well and liver function is normal. Conclusions The umbilical metastasis can arise from many sites. In some cases, primary tumor may be not identified; nonetheless chemotherapy must be administrated based on patient's history, anatomical and histological findings. PMID:15651984

Dengue fever is one of the commonest mosquito-borne diseases in the tropics, and Sri Lanka is no exception. Despite its commonness, dengue fever has rarely been described among patients who have undergone transplantation. We report the case of a patient with dengue fever after liver transplantation, which, to the best of our knowledge, is the first such reported case outside Brazil. Our patient was a 46-year-old Sri Lakan man who presented to our institution two years after undergoing an ABO-compatible cadaveric liver transplant. At presentation, he had typical symptoms of dengue fever. He was taking prednisolone 5mg daily and tacrolimus 3mg twice daily as immunosuppression. Initial investigations showed thrombocytopenia and neutropenia that reached a nadir by day 7 of his illness. He had elevated liver enzymes as well. The diagnosis was confirmed on the basis of NS1 antigen detection by enzyme-linked immunosorbent assay. His blood cultures and polymerase chain reaction tests for cytomegalovirus were negative. He made an uneventful recovery and was discharged by day 9 of his illness. However, normalization of liver function took nearly two weeks. In three previously reported Brazilian cases of dengue after liver transplantation, the patients presented with dengue shock syndrome, in contrast to the relatively milder presentation of our patient. Because of the lack of case reports in the literature, it is difficult to ascertain the risk factors for severe dengue infection in transplants, but dengue fever reported in renal transplants sheds some light on them. High-dose steroids increase the risk of thrombocytopenia, whereas tacrolimus has been reported to prolong the duration of symptoms. Otherwise, dengue fever is a relatively mild illness in patients who have undergone renal transplantation, and renal allograft survival has been reported to be 86% following dengue fever. Dengue is a rarely reported infection in patients who have undergone transplantation. A high

MSUD occurs due to deficiency of enzyme BCKAD required for metabolism of leucine, isoleucine, and valine leading to the accumulation of these and their ketoacids causing acute metabolic decompensation manifesting as encephalopathy or sudden death. The patient requires special protein-restricted diet to survive. As this enzyme is expressed in liver, liver transplantation has been successfully performed as a cure. We report two patients of MSUD who underwent LDLT while their livers were used as a domino graft for other biliary cirrhotic patients. A 22-month-old male child diagnosed as a case of classic MSUD underwent LDLT from an altruistic aunt as donor following which his serum leucine levels normalized on an unrestricted protein diet. His liver was used as a domino graft. A 38-month-old female child with diagnosed MSUD underwent LDLT from a swap donor, and her liver was used as a domino graft. Her DQ improved post-transplant. LDLT from non-heterozygous donors is a cure for classical MSUD. Their livers can be used as domino grafts for non-MSUD cases. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

There are few descriptions of severe thrombocytopenia during the early postoperative period after liver transplantation, and these have not been fully documented in the literature. Here, we report a case of drug-induced thrombocytopenia requiring transfusion of blood products after living donor liver transplantation. We determined that this was not caused by the interferon-free anti-viral therapy but by tacrolimus A 61-year-old woman with hepatitis C-related cirrhosis and hepatorenal syndrome underwent living donor liver transplantation using a left lobe graft from her son. After transplantation, immunosuppression consisted of tacrolimus and steroid. Seven weeks after transplantation, interferon-free therapy with daclatasvir and asunaprevir was started. Thirteen days thereafter, hepatitis C virus tested negative. However, the platelet count had begun to gradually decrease just before starting anti-viral therapy. Daclatasvir and asunaprevir were stopped because this was suspected to be a side-effect of these drugs, but the patient nonetheless went on to develop severe thrombocytopenia (platelet count 17,000/μL), which needed transfusions. Now suspecting tacrolimus as the inducer of this side effect, we changed to cyclosporin, after which the platelet count gradually recovered. Viral markers were still not detectable up to 2 months after discontinuation of the antiviral drugs. We conclude that when severe thrombocytopenia occurs, possible drug-induced thrombocytopenia as well as other disorders must be investigated.

Organ grafts developed in the xenogeneic pig scaffold are expected to resolve most issues of donor safety and ethical concerns about living-donor liver transplantation in Japan. We have been working on so-called “Yamaton” projects to develop transplantable organs using genetically engineered pigs. Our goal is to produce chimeric livers with human parenchyma in such pigs. The Yamaton-Liver project demonstrated the proof of concept by showing that rat–mouse chimeric livers could develop in mice and be successfully transplanted into syngeneic or allogeneic rats. Under conventional immunosuppression, the transplanted livers showed long-term function and protection against rejection. Because chimeric liver grafts have xenogeneic components, additional strategies, such as humanization of pig genes, induction of hematopoietic chimeras in donors, and replacement of pig endothelial cells with human ones, might be required in clinical use. Our projects still need to overcome various hurdles but can bring huge benefits to patients in the future. PMID:23896578

Posttransplant lymphoproliferative disorders (PTLDs) are among the most serious and potentially fatal complications of both stem-cell and solid-organ transplantation. Most monomorphic PTLDs are of B-cell origin and frequently associated with Epstein-Barr virus (EBV) infection in the setting of pharmacological immunosuppression posttransplantation. The majority of monomorphic PTLDs commonly resemble diffuse large B-cell or Burkitt's lymphoma; plasmacytoma-like PTLDs are very rare. We report a case of plasmacytoma-like PTLD arising in the allograft in a 66-year-old male diagnosed 2 months following an orthotopic liver transplant for alcohol-related end-stage liver disease. The liver biopsy revealed marked infiltration of atypical plasma cells with lambda light chain restriction and positivity for EBV by in situ hybridization confirming the diagnosis. Also noted was a remarkable increase of tissue eosinophils. Reduction of immunosuppression led to improvement in his clinical condition, and also resolution of the hepatic lesions and abdominal lymphadenopathy noted on imaging studies. While a few cases of plasmacytoma-like PTLDs have been described in literature, to our knowledge, this is the first reported case of early onset plasmacytoma-like PTLD in a liver transplant recipient occurring in the allograft with associated lymphadenopathy having distinct histopathologic features including tissue eosinophilia. Timely recognition of such an entity is critical in order to initiate early and appropriate intervention.

Pancreatic panniculitis is an uncommon condition that can occur in association with pancreatic disease. Most of the cases reported to date were associated with acute or chronic pancreatitis and pancreas cancer. Recently, development has been described in kidney transplant patients and secondarily to allograft pancreatitis in a pancreas-kidney transplant recipient. Both findings suggest that immunological processes may be involved in the pathogenesis of this entity. We report for the first time a case of acute pancreatitis associated with pancreatic panniculitis in a patient who underwent a liver transplant 10 months before. A 69-year-old man with a history of epigastric pain of a few days of evolution was presented with painful subcutaneous nodules on both legs. Blood chemistry showed raised serum amylase and lipase levels. Ultrasonography and multislice CT scan were suggestive of an acute pancreatitis. A skin biopsy showed typical features of pancreatic panniculitis which included lobular panniculitis with lipocyte degeneration with ghost cells. The administration of octreotide resulted in both a rapid improvement of symptoms and a disappearance of skin lesions. Liver transplant specialists should be aware that the pancreatic panniculitis could be a manifestation ofpancreas disease in patients who have undergone l ver transplantation.

Intra- or extrahepatic cholangiocarcinomas are the second most common primary liver malignancies behind hepatocellular carcinoma. Whereas the incidence for intrahepatic cholangiocarcinoma is rising, the occurrence of extrahepatic cholangiocarcinoma is trending downwards. The treatment of choice for intrahepatic cholangiocarcinoma remains liver resection. However, a case of liver resection after selective internal radiation therapy in order to treat a recurrent intrahepatic cholangiocarcinoma in a transplant liver is unknown in the literature so far. Herein, we present a case of a patient undergoing liver transplantation for Wilson's disease with an accidental finding of an intrahepatic cholangiocarcinoma within the explanted liver. Due to a recurrent intrahepatic cholangiocarcinoma after liver transplantation, a selective internal radiation therapy with yttrium-90 microspheres was performed followed by right hemihepatectomy. Four years later, the patient is tumor-free and in a healthy condition.

Living donor liver transplantation (LDLT) is an important means to treat end-stage liver disease. Although effective immunosuppressant medication greatly assists the survival of patients, it is likely to promote infections and cancer. Acute leukemia (AL) is a rare complication after LDLT and up to now only 1 case of post-transplantation AL has occurred in our liver transplantation center after more than 1,600 LDLT interventions since 1993. In the present report, we describe a rare case of subsequent acute myeloid leukemia (AML), 27 months after LDLT and review the literature of this infrequent complication. PMID:26722593

Solid organ transplantation is an accepted therapy for end-stage diseases of the kidneys, liver, heart, and lungs. Unfortunately, transplantation is associated with infectious complications. Here, we present a case report of Prototheca wickerhamii olecranon bursitis and review all of the cases in solid organ transplant (SOT) recipients published in the literature to date. In our patient, the infection resolved with surgical therapy and limited antifungal therapy, and no symptoms have recurred over 24 months of follow-up. A review of the literature suggests that 50% of SOT recipients with Prototheca infection present with disseminated infection, and the overall mortality is 75%. More studies are required to determine the optimal management of protothecosis in this population. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The liver transplant patient was admitted to the hospital with hyperemic, granulomatous, ulcerated lesion in the anterior compartment of the right lower limb with report of local trauma. The agent Sporothrix schenckii was isolated from biopsy of the lesion and lymph nodes of the right lower limb. In this case, the treatment was difficult because the patient has severe pulmonary hypertension and took the following drugs: warfarin, sildenafil, and tacrolimus. These medicines interact with the antifungal, which made it difficult.

Solid-organ transplant graft-versus-host disease (SOT-GVHD) is a rare complication of organ transplant that is associated with high mortality. The initial signs and symptoms are vague, so this disease is easily confused with other posttransplant complications. A case of SOT-GVHD occurred after orthotopic liver transplant for liver failure due to hepatitis C in a patient in a Veterans Affairs intensive care unit. The patient had dehydration, acute kidney injuries, rashes, diarrhea, and pancytopenia. Results of skin biopsy, bone marrow biopsy, and cytogenetic studies were consistent with SOT-GVHD. Despite supportive care including antibiotics, antiviral and antifungal therapy, high-dose steroids, antithymoglobulin and neupogen, the patient died of overwhelming sepsis. Owing to the rarity of SOT-GVHD, no evidence-based guidelines or recommendations for treatment exist. Treatment includes high-dose corticosteroids and antibiotic, antifungal, and antiviral prophylaxis. Treatment of liver transplant-related GVHD with anti-tumor necrosis factor a agents has been successful. ©2016 American Association of Critical-Care Nurses.

Seizure is the second most common neurologic complication after liver transplantation and may be caused by metabolic abnormalities, electrolyte imbalance, infection, and immunosuppressant toxicity. A 61-year-old male patient underwent liver transplantation due to hepatitis B virus-related liver cirrhosis with portal systemic encephalopathy. The immediate postoperative course of the patient was uncomplicated. However, on postoperative day (POD) 6, weakness developed in both lower extremities. No abnormal findings were detected on a brain computed tomography (CT) scan on POD 8, but a generalized tonic clonic seizure developed which was difficult to control even with multiple antiepileptic drugs. A follow-up brain CT scan on POD 15 showed a 2.7 cm sized acute intracranial hemorrhage (ICH) in the left parietal lobe. The patient's mental status improved after 2 months and he was able to communicate through eye blinking or head shaking. Our case reports an acute ICH that manifested into a refractory seizure in a patient who underwent a liver transplant. PMID:27703637

Bile duct stones and casts (BDS) after liver transplantation are associated with significant morbidity. Risk factors for BDS formation and the efficacy of treatment in liver transplant recipients have not been systematically studied. The aim of this study was to evaluate potential risk factors for the formation of BDS in patients post-liver transplant. A case-control study of consecutive liver transplant recipients at a university hospital from 1989 to 2007 was performed to identify risk factors for BDS formation. Cases included all liver transplant recipients with BDS, excluding those with concurrent t-tubes or biliary stents. Controls were chosen randomly from the total liver transplant population matched for year of transplantation. Pre- and post-OLT risk factors were analyzed with univariate and multivariate analyses. There were 49 cases and 101 controls over an 18-year-period (1289 liver transplants performed) with an incidence of 3.8% for BDS. In the cases, the median time to BDS diagnosis was 613 days from time of transplant. The controls had a median follow-up of 1530 days. Use of ursodeoxycholic acid was protective (P = 0.005), whereas bile duct pathology (P = 0.003), total cholesterol >/= 200 mg/dL (P = 0.008), and triglyceride >/= 150 mg/dL (P = 0.008) were significant risk factors for BDS formation. Endoscopic retrograde cholangiopancreatography (ERCP) was technically successful in all cases with resolution or improvement of liver chemistries in 59% (29) of patients. In conclusion, significant risk factors for forming BDS included bile duct pathology and elevated total cholesterol and triglyceride levels. Ursodeoxycholic acid had a significant effect in preventing the development of posttransplant BDS and should be used in those that are at increased risk. ERCP is a safe and effective diagnostic and therapeutic modality for these patients.

Portal vein thrombosis is common in patients with end-stage liver disease, with an incidence as high as 26% in liver transplant candidates. It is known to be associated with a high risk of morbidity and mortality posttransplantation, and its management can be challenging. The management options range from a simple thrombendvenectomy to multivisceral transplantation in cases with diffuse portomesenteric thrombosis. We report a case of liver transplantation in which we performed a rare reconstruction of the portal vein. Briefly, the patient had diffuse portomesenteric thrombosis, calcified aneurysmosis, and a large collateral coronary vein, to which we directly anastomosed the donor portal vein in an end-to-side fashion. This report describes a unique surgical approach for similar cases of severe portal vein thrombosis in liver transplant candidates.

Yttrium-90 microspheres constitute one of the most recent treatment options for hepatocellular carcinoma (HCC) in the setting of cirrhosis. As such, their spectrum of indication is not yet fully established. Herein, we have reported the case of a patient with HCC beyond the listing criteria for liver transplantation (OLT) who was treated preoperatively with selective transarterial chemoembolization and yttrium-90 microspheres. He was subsequently transplanted with a liver from an 81-year-old donor allocated through Eurotransplant as a "rescue offer." The posttransplant course was uneventful. Pathologic examination revealed a multifocal, well-differentiated pT2 tumor with no vascular invasion. The patient is currently alive and in good condition at 14 months posttransplant, with no evidence of tumor recurrence by a current computed tomography scan. This report provided encouraging information on the potential of yttrium-90 microspheres as a bridging option before OLT for multifocal HCC.

Background and Aim Liver transplantation is a potential cure for liver damage from Wilson’s disease but the course of neuropsychiatric manifestations after transplantation remains undetermined. Material and methods In this study, data on all patients who’d received a liver transplant for Wilson’s disease at the Shiraz Organ Transplantation Center between December 2000 and March 2014 were reviewed and compared to data on a control group who’d received a liver transplant over the same period but due to other causes. Results Out of 2198 patients who’d received a liver transplant in the period; 107 patients were diagnosed with Wilson’s disease (21 with fulminant hepatic failure); age of patient ranged from 5 to 59 years; 56.07% of patients in this series had some type of neuropsychiatric manifestation before transplantation, of which 66.67% showed improvement after the procedure. 18 patients had aggravation of neuropsychiatric symptoms after transplantation. These neuropsychiatric symptoms were mostly for anxiety, tremor and depression but there were four cases of new onset dysarthria, rigidity and ataxia in various combinations. Survival rates of 1-month, 1-year, and 5-years for patients with Wilson’s disease were 88%, 86%, 82%, respectively, evaluations were not statistically different from that of the control group. Conclusions Liver transplantation showed good long-term results in patients with Wilson’s disease, even in those presenting fulminant hepatic failure. Neuropsychiatric manifestations normally show improvement after transplantation but in some cases new onset of manifestations occurred after successful liver transplantation. PMID:27930723

The shortage in cadaveric grafts has prompted the development of alternative surgical techniques to expand the donor pool. To evaluate the feasibility of split liver transplantation using an observational, retrospective, and longitudinal study. Between April 1986 and October 2002 we performed 875 liver transplants. From April 1991 to date, we performed 18 split liver transplantations in patients of mean age 42.27+/-25.65 years; five children and 13 adults; and 83.3% women. Urgent transplants accounted for 38.9%. Mean patient weight was 52.29+/-20.87 kg. Ex situ splitting was performed in 33%. The mean cold ischemia time was 460+/-265.69 minutes with a mean warm time of 64.33+/-11.78 minutes. Mean consumption of packed blood was 5.59+/-4.87 units; of frozen fresh plasma, 11.56+/-7.42 units; and of platelets 4.89+/-4.99 units. After a mean follow-up of 10.83+/-12.51 months, 55.56% of the recipients are alive. Actuarial patient and graft survival rates at 1 year are 55.6% and 44.12%, respectively. Actuarial patient and graft survival rates at 1 year, excluding operative mortality were 77% and 68%, respectively. Actuarial patient and graft survival rates at 1 year, comparing urgent and elective transplantations are: 14.29 and 14%, respectively, for urgent cases and 90.91 and 90% for elective ones. Operative mortality was 16.6% while mortality during follow-up was 26.6%. The late complications included arterial thrombosis (n=2): of whom the first needed liver retransplantation 4 months after split liver transplantation; chronic rejection (n=2), recurrence of hepatitis (n=1). Split liver transplantation is a useful way to expand the graft pool and shows better results in elective liver transplantation.

Liver transplantation from a brain death donor has not yet been accepted in Japan. The only alternative method at present is transplantation from a living donor. After the first successful living related liver transplantation was performed by Strong in Brisbane, Australia, Japanese hepatic and transplant surgeons also began to perform such operations. As of February 1991, 16 living related liver transplantations had already been performed in Japan, mainly for children with biliary atresia. Five of these patients subsequently died, however, our patient has survived more than 1 year, and she is presently leading a normal school life. The most important issue regarding living related liver transplantation is to ensure the donor's safety. For this purpose, we conducted a preoperative banking of the donor's own blood and plasma. In addition, a selective vascular occlusion was carried out to reduce blood loss during the resection of the liver. Intraoperative color Doppler ultrasonography was introduced for evaluating the circulation of the graft. By using this modality, the following three points were able to be accurately estimated in order to obtain optimal graft perfusion: 1) The most suitable position for the graft to be fixed to the abdominal wall, 2) whether or not the abdominal wall could be closed and 3) the indication for a ligation of the collateral veins to form a porto-systemic shunt. Thanks to these procedures, living related liver transplantations have now become an acceptable transplant method, however, a transplantation from a cadaver that is brain dead but still has a beating heart is still absolutely necessary for adult recipients. Therefore, in the future, both methods should be performed.

Helicobacter cinaedi (H. cinaedi), a Gram-negative spiral-shaped bacterium, is an enterohepatic non-Helicobacter pylori Helicobacter species. We report the first case of H. cinaedi bacteremia with cellulitis after liver transplantation. A 48-year-old male, who had been a dog breeder for 15 years, underwent ABO-incompatible living-donor liver transplantation for hepatitis C virus-induced decompensated cirrhosis using an anti-hepatitis B core antibody-positive graft. The patient was preoperatively administered rituximab and underwent plasma exchange twice to overcome blood type incompatibility. After discharge, he had been doing well with immunosuppression therapy comprising cyclosporine, mycophenolate mofetil, and steroid according to the ABO-incompatible protocol of our institution. However, 7 mo after transplantation, he was admitted to our hospital with a diagnosis of recurrent cellulitis on the left lower extremity, and H. cinaedi was detected by both blood culture and polymerase chain reaction analysis. Antibiotics improved his symptoms, and he was discharged at day 30 after admission. Clinicians should be more aware of H. cinaedi in immunocompromised patients, such as ABO-incompatible transplant recipients.

Ornithine transcarbamylase deficiency represents the most common inherited defect of the urea cycle. This enzyme, predominantly found in the liver, plays a crucial role in recycling free ammonia, with deficiencies often leading to fatal complications. Here, we present the case of a 63-year-old man with alcoholic cirrhosis who underwent orthotopic liver transplantation, gradual worsening of his mental status, and progressive elevation of ammonia levels. Liver allograft function was deemed normal, raising concern for a donor-derived metabolic disorder of the urea cycle. Evaluation of the donor patient's blood revealed that the donor was heterozygous for the OTC gene. Posttransplantation changes in mental status should prompt a clinician to consider the most likely causes; however, once these have been ruled out, it is important to consider the less common causes of metabolic derangements. The rarity of these disorders makes expertise of diagnosis, standardization of evaluation, and treatment strategies challenging.

Liver transplantation (LT) activity started in Spain in 1984 and has exceeded 23,700 interventions, with more than 1000 transplants performed yearly. Every hospital needs official authorization to perform a LT, which implies the obligation to register all patients on the national waiting list. The Spanish National Transplant Organization (ONT) provides essential support for organ procurement, allocation, and management of the waiting list at a national level. Liver allocation is center-oriented as all available organs are referred to the ONT for the whole country. The allocation rules for LT are made according to disease severity after consensus among professionals from every transplant center and ratified by representatives of the regional health authorities. Authorization and location/distribution of transplant centers are regulated by the country (Spain) and by the different regions according to the Real Decreto 1723/2012. For a total population of 47,850,795 inhabitants, there are 24 centers for LT for adults (1 team/2 million people) and 5 for LT for children (1 team/9.5 million people). Nonbiliary cirrhosis, particularly alcohol- and hepatitis C virus-related cirrhosis (60%), and tumors, mainly hepatocellular carcinoma (19%), are the most common indications for LT in Spain. Unusual causes of LT include metabolic diseases like Wilson's disease, familial amyloid polyneuropathy and hyperoxaluria type I, polycystic kidney and liver disease, and some tumors (epithelioid hemangioendothelioma and neuroendocrine tumors). Important efforts are now being undertaken to improve the quality and transplantability of extended criteria livers, in particular those arising from DCD, which represent the greatest opportunity to expand the donor pool. These efforts have to be addressed to adapt the organ preservation procedures, be it through the application of regional perfusion in situ or the use of machine perfusion preservation ex situ.

Graft-versus-host disease (GVHD) is a frequent complication of bone marrow transplantation (BMT). Chronic GVHD (cGVHD) may lead to irreversible liver failure. We report a case of successful liver transplantation (LT) for end-stage liver failure because of cGVHD that had developed 22 months after BMT in a 24-year-old male. Re-transplantation was necessary 6 months later because of intrahepatic ischaemic type biliary tract lesions. He is now in excellent condition 10 years after the first transplant. This experience and the review of literature indicate that LT can cure GVHD-related chronic liver failure. Recurrent GVHD in the allograft has not yet been reported.

The liver transplantation technique advances have allowed the endovascular treatment of stenosis between hepatic vein and inferior vena cava, and this has become an established and widely acceptable method for the treatment of patients with end-stage liver disease. However, in spite of the advances in the surgical technique of liver transplantation there is relatively still a high incidence of postoperative complications, especially those related to vascular complications. One technical variant of orthotopic liver transplantation is the piggyback technique with conservation of the recipient vena cava, which is anastomosed to the graft hepatic veins. As a consequence of the increased number of liver transplants in children, there is a higher demand for endovascular treatment of vascular stenosis, such as those at the level of the hepatic veins. This leads to more consistent experience of endovascular treatment of the surgical vascular complications following liver transplantation. This article describes the case of a child submitted to liver transplantation with reduced graft (left lateral segment) who presented stenosis of the anastomosis between the hepatic vein and IVC 6 months later which was successfully treated by PTA.

Liver transplantation was the product of 5 interlocking themes. These began in 1958-59 with canine studies of then theoretical hepatotrophic molecules in portal venous blood (Theme I) and with the contemporaneous parallel development of liver and multivisceral transplant models (Theme II). Further Theme I investigations showed that insulin was the principal, although not the only, portal hepatotrophic factor. In addition to resolving long-standing controversies about the pathophysiology of portacaval shunt, the hepatotrophic studies blazed new trails in the regulation of liver size, function, and regeneration. They also targeted inborn metabolic errors (e.g. familial hyperlipoproteinemia) whose palliation by portal diversion presaged definitive correction with liver replacement. Clinical use of the Theme II transplant models depended on multiple drug immunosuppression (Theme III, Immunology), guided by an empirical algorithm of pattern recognition and therapeutic response. Successful liver replacement was first accomplished in 1967 with azathioprine, prednisone, and ALG. With this regimen, the world’s longest surviving liver recipient is now 40 years postoperative. Incremental improvements in survival outcome occurred (Theme IV) when azathioprine was replaced by cyclosporine (1979) which was replaced in turn by tacrolimus (1989). However, the biologic meaning of alloengraftment remained enigmatic until multilineage donor leukocyte microchimerism was discovered in 1992 in long surviving organ recipients. Seminal mechanisms were then identified (clonal exhaustion-deletion and immune ignorance) that linked organ engraftment and the acquired tolerance of bone marrow transplantation and eventually clarified the relationship of transplantation immunology to the immunology of infections, neoplasms, and autoimmune disorders. With this insight, better strategies of immunosuppression have evolved. As liver and other kinds of organ transplantation became accepted as

MSUD is a complex metabolic disorder that has been associated with central nervous system damage, developmental delays, and neurocognitive deficits. Although liver transplantation provides a metabolic cure for MSUD, changes in cognitive and adaptive functioning following transplantation have not been investigated. In this report we present data from 14 patients who completed cognitive and adaptive functioning testing pre- and one year and/or three years post-liver transplantation. Findings show either no significant change or improvement in IQ scores pre- to post-liver transplantation. Greater variability was observed in adaptive functioning scores, but the majority of patients evidenced either no significant change or improvement in adaptive scores. In general, findings may indicate that liver transplantation curtails additional central nervous system damage and neurocognitive decline providing an opportunity for stabilization or improvement in functioning.

Liver transplantation (LT) is the treatment of choice for localized hepatocellular carcinoma (HCC) associated with cirrhosis. Extra hepatic metastasis is the most common cause of death in these patients. There is very little evidence regarding the natural history and treatment options for patients developing HCC recurrence after LT. Surgical resection offers a unique opportunity for solitary metastasis. We report a 61 year old male with solitary right adrenal metastasis 15 months post LT which was managed with open adrenalectomy. The patient is alive and disease free 24 months after the surgery. The case, histo-pathological findings and literature review is discussed.

The percentage of overweight and obese patients (OPs) waiting for a liver transplant continues to increase. Despite the significant advances occurred in bariatric medicine, obesity is still considered a relative contraindication to liver transplantation (LT). The main aim of this review is to appraise the literature on the outcomes of OPs undergoing LT, treatments that might reduce their weight before, during or after surgery, and discuss some of the controversies and limitations of the current knowledge with the intent of highlighting areas where future research is needed.

Diaphragmatic hernia is an unusual complication after pediatric liver transplant. Nearly half of bowel obstruction cases, which require surgical intervention in liver transplant patients, are caused by diaphragmatic hernia. The smaller patients are at risk for higher rates of diaphragmatic complication after pediatric liver transplant, but diaphragmatic hernia has not been reported as a unique occurrence. Here, we report 3 cases of diaphragmatic hernia after liver transplant and discuss the possible contributing factors. Diaphragmatic hernia should nevertheless be added to the list of potential complications after liver transplant in the pediatric population. Pediatric transplant physicians and surgeons should be aware of this complication so that it is recognized promptly in both acute and nonacute settings and appropriate action is taken.

We report three cases of Kaposi's sarcoma after orthotopic liver transplantation performed for cirrhosis related to hepatitis C virus (one case), ethanol (one case), or both (one case). All patients displayed disease within the first year after liver transplantation, and only in one case was the diagnosis obtained before the patient died. All three patients were on tacrolimus-steroid therapy, and in one case mycophenolate mofetil was added to treat acute persistent rejection.
This article addresses postoperative analgesia in patients with end-stage liver disease who have undergone liver transplantation (LT). Postoperative analgesia determines how patients perceive LT. Although important, this topic is underrepresented in the current literature. With an increased frequency of fast tracking in LT, efficient intra- and postoperative analgesia are undergoing changes. We herein review the current literature, compare the benefits and disadvantages of the therapeutic options, and make recommendations based on the current literature and clinical experience.

To evaluate the safety to donors of living-donor liver transplantation. This study included 300 consecutive living liver tissue donors who underwent operations at our center from July 2002 to December 2012. We evaluated the safety of donors with regard to three aspects complications were recorded prospectively and stratified by grade according to Clavien's classification, and the data were compared in two stages (the first 5 years' experience (pre-January 2008) and the latter 5 years' experience (post-January 2008); laboratory tests such as liver function and blood biochemistry were performed; and the health-related quality of life was evaluated. There was no donor mortality at our center, and the overall morbidity rate was 25.3%. Most of the complications of living donors were either grade I or II. There were significantly fewer complications in the latter period of our study than in the initial period (19.9% vs 32.6%, P<0.001), and biliary complications were the most common complications, with an incidence of 9%. All of the liver dysfunction was temporary; however, the post-operative suppression of platelet count lasted for years. Although within the normal range, eight years after operation, 22 donors showed lower platelet levels (189 × 10(9)/L) compared with the pre-operative levels (267 × 10(9)/L) (P<0.05). A total of 98.4% of donors had returned to their previous levels of social activity and work, and 99.2% of donors would donate again if it was required and feasible. With the exception of two donors who experienced grade III complications (whose recipients died) and a few cases of abdominal discomfort, fatigue, chronic pain and scar itching, none of the living donors were affected by physical problems. With careful donor selection and specialized patient care, low morbidity rates and satisfactory long-term recovery can be achieved after hepatectomy for living-donor liver transplantation.

Women constitute >30% of patients undergoing liver transplantation (orthotopic liver transplantation, OLT) and about 8% are of reproductive age, and 5% are pediatric females who will mostly survive into adulthood and will consider pregnancy. Although pregnancy in OLT recipients is associated with an increased incidence of hypertension, preeclampsia, anemia, preterm deliveries, and cesarean section, acute rejection and liver allograft loss do not appear to be increased and pregnancy-related maternal death is uncommon. The incidence of structural malformations in the newborn of liver transplant recipients is reported to be 4.4%, which is similar to the rate of 3-5% in the US general population. Patients are advised to defer conception for at least 1-2 years after OLT, while maintaining effective contraception. Pregnancy after OLT usually results in a favorable maternal and neonatal outcome when there is coordinated pre- and perinatal care by a multidisciplinary team composed of obstetric-gynecologists, and a transplant team.

Guidelines for surgery in patients treated with vitamin K antagonist recommends to correct international normalized ratio (INR), although they do not focus on liver transplantation candidates. We report two patients treated with vitamin K antagonist, monitored by thromboelastometry during liver transplantation. Case 1: basal INR was 3.15. Extem coagulation time was 83 s and maxim clot firmness was 60 mm. The surgical procedure did not show bleeding. Two red blood cells were transfused and no other blood products were administered. Last INR was 3.17. Case 2: basal INR was 2.79. A thrombocytopenia of 58 000/mm was detected. Extem coagulation time was 176 s, and maxim clot firmness was 40 mm. Fibtem maxim clot firmness was 11 mm. The surgical procedure did not show bleeding. No blood product was administered. Last INR was 2.1. Although thromboelastometry did not correlate with INR, monitoring of the coagulation using thromboelastometry in combination with surgery helped to conduct hemostatic corrections.

Before liver transplantation became widely applicable as a treatment option, the mortality rate for acute liver failure was as high as 85%. Today, acute liver failure is a relatively common transplant indication in some settings, but the results of liver transplantation in this context appear to be worse than those for chronic forms of liver disease. In this review, we discuss the indications and contraindications for urgent liver transplantation. In particular, we consider the roles of auxiliary, ABO-incompatible, and urgent living donor liver transplantation and address the management of a «status 1» patient with total hepatectomy and portocaval shunt for toxic liver syndrome.

Liver transplantation is the definitive therapy for patients with advanced liver disease and its complications. Patients who are transplanted with a diagnosis of hepatocellular carcinoma (HCC) are at risk of recurrent cancer, and these patients are monitored on a regular basis for recurrence. In contrast, de novo HCC following liver transplantation is a very rare complication, and recipients without HCC at the time of transplantation are not screened. We describe the clinical features of de novo HCC over a decade after achieving a sustained viral response with treatment of hepatitis C and two decades after liver transplantation. Our case highlights the necessity of screening for HCC in the post-transplant patient with advanced liver disease even after viral clearance. PMID:26807385

We report a case of an intrahepatic arterioportal fistula in a 61-year-old female liver transplant recipient. The patient presented with massive ascites 7 months after a percutaneous liver biopsy. A large fistula between the right hepatic artery and the right portal vein was diagnosed on color Doppler ultrasound and confirmed on arteriography. The fistula was successfully embolized with the detachable balloon technique and the ascites resolved. Symptomatic intrahepatic arterioportal fistula in a liver transplant recipient following percutaneous biopsy is rare. Clinical manifestations, surgical or endovascular therapy, and outcome are discussed. The literature on this subject is reviewed.

Encapsulating peritoneal sclerosis (EPS) is a rare cause of intestinal obstruction by a thick fibrous membrane wrapping around the small intestine. It is a possible complication after liver transplantation (LT) that can be fatal. This report describes 2 cases of EPS after LT that were successfully treated with surgery, corticosteroids, tamoxifen, and mammalian target of rapamycin inhibitor. After treatment in both cases, the patients were able to start oral feeding and have been symptom free for more than 1 year. These cases suggests that for the management of EPS, surgical treatment is mandatory when the patients present with symptoms of intestinal obstruction or if there are findings suggestive of decreased mural perfusion. Surgery should be accompanied with medical treatment to prevent the relapse of EPS. PMID:28289671

Improved outcomes in liver transplant recipients reflect advances in surgical technique, post-operative care, immunosuppression as well as better selection of potential candidates. The pre-transplant evaluation is a multidisciplinary process intended to recognize and treat important comorbid conditions that may impair outcomes during the peri- and post-transplant periods. Important psychosocial issues should also be ascertained and tackled early during the pre-transplant evaluation with an overarching intention to improve the success of liver transplantation.

Since the first clinical orthotopic liver transplant was performed 13 years ago, approximately 275 patients have undergone this procedure. The Denver series constitutes about 40% of this total experience. In our series, the overall 1-year survival has been 29%; the longest survivor is now 62/3 years posttransplantation. Most of the early deaths have been caused by technical complications, frequently related to difficulties in establishing and maintaining adequate biliary drainage. The late deaths have been from a variety of causes, including recurrent tumor, hepatitis, bile duct obstruction, and chronic rejection. Favorable indications for liver transplantation include biliary atresia, chronic aggressive hepatitis, inborn errors of metabolism, and certain other benign hepatic diseases. Alcoholic cirrhosis is a less favorable indication and primary hepatic malignancy is a relative contraindication. The immunologic criteria for donor-recipient selection are much less rigid than for renal transplantation. Biliary reconstruction is the principal technical problem encountered with orthotopic liver transplantation. Guidelines for the establishment of biliary drainage, its evaluation, and the management of postoperative biliary complications are discussed. PMID:325920

The enzymatic defect in MSUD results in accumulation of neurotoxic metabolites of BCAAs. LTX has shown to be a feasible strategy in patients non-responsive to diet. Because of sufficient enzyme activity in extrahepatic tissues in healthy people, the MSUD liver graft is a suitable domino organ. We present the first case of a technical challenging ex situ split of a MSUD domino organ transplanted into two pediatric recipients. The domino graft donor was a 21-year-old female (58 kg) suffering from MSUD with recurrent metabolic decompensation despite strict diet. The organ was allocated to a 14-year-old girl (55 kg) with primary sclerosing cholangitis. Due to excellent organ quality and suitable anatomy, a backward split for a girl of 3 months (5 kg) with decompensated liver cirrhosis due to biliary atresia was performed. The postoperative course was without relevant complications, and the three recipients were discharged on postoperative days 28, 29, and 45, respectively, with good organ function. BCAAs in plasma were normal in the two domino graft recipients, and the MSUD patient showed mildly elevated but stable BCAA concentrations despite an unrestricted diet. Split-domino LTX enabled successful transplantation of three patients of the waiting list with only one deceased donor graft. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Small bowel obstruction in a pediatric patient following liver transplant often results from adhesions, hernias, or post-transplant lymphoproliferative disease. Here, we present an unusual and previously unreported entity - Roux-en-Y intussusception in an eight-yr-old female several years after liver transplantation. Although a rare complication, Roux-en-Y intussusception should be considered as a potential etiology in the patient presenting with bowel obstruction, with specific attention to acute presentation accompanying jaundice. © 2016 John Wiley & Sons A/S.

The shortage of deceased donor liver grafts led to the use of living donor liver transplant (LDLT). Patients who undergo LDLT have a higher risk of complications than those who undergo deceased donor liver transplantation (LT). Interventional radiology has acquired a key role in every LT program by treating the majority of vascular and non-vascular post-transplant complications, improving graft and patient survival and avoiding, in the majority of cases, surgical revision and/or re-transplant. The aim of this paper is to review indications, diagnostic modalities, technical considerations, achievements and potential complications of interventional radiology procedures after LDLT.

Pediatric liver transplantation is the standard of care for treatment of liver failure in children. The aim of this study was to identify the characteristics of pediatric liver transplantation in centers located in Korea and determine factors that influence outcomes. This retrospective study was performed using data from between 1988 and 2010 and included all recipients 18 yr old and younger who underwent pediatric liver transplantation in Korea during that period. Our data sources were hospital medical records and the outcome measure was overall patient survival. Univariate and multivariate statistical analyses were undertaken using the Cox proportional hazards model. Five hundred and thirty-four pediatric liver transplantations were performed in 502 children. Median age and average pediatric end-stage liver disease (PELD) score were 20 months and 18 point, respectively. Biliary atresia (57.7%, 308/534) was the most common cause of liver disease. Eighty-two (15.3%) were deceased donor liver transplantations and 454 (84.7%) were living donor liver transplantations. Retransplantation was performed in 32 cases (6%). Overall, 1-, 5-, and 10-yr patient survival rates were 87.8%, 82.2%, and 78.1%, respectively. In multivariate analysis, independent significant predictors of poor patient survival were chronic rejection and retransplantation. This study presents the epidemiologic data for nearly all pediatric liver transplantation in Korea and shows that the independent prognostic factors in patient survival are chronic rejection and retransplantation.

To evaluate the living donor selection, donor hepatectomy technique, and surgical complication in living donor liver transplantation. From June 2007 to July 2008, 74 consecutive cases living donor hepatectomy were performed by the same surgical team. Seventy-four donors (64 males and 10 females) with a mean age of 29.2 years old passed the donor liver assessment and evaluation program successfully. The hepatectomy procedure types contained right liver resection (n = 72), of which 27 cases harvested the middle hepatic vein and 45 cases not, left liver resection contain middle hepatic vein (n = 1) and left lateral resection (n = 1). Of all the donors, operation time was (6.5 +/- 6.2) hours, the mean blood loss was 300 ml (100 - 500 ml) and didn't accept foreign blood transfusion. The maximum alanine aminotransferase (ALT) level was (229.5 +/- 108.6) U/L, the ALT returned to normal time was (12.7 +/- 4.8) d, the maximum total bilirubin (TB) level was (78.7 +/- 44.3) micromol/L, the TB returned to normal time was (8.8 +/- 2.7) d, and the mean hospital stay time was 14 days (7 - 28 d). The complications included bile leak (n = 1), cut surface hemorrhage (n = 1) and anaphylactoid purpura (n = 1). All the donors returned to normal work and life finally. Precisely evaluating donor blood vascular and biliary anatomy before operation, keeping the blood vascular and bile duct integrity during operation and monitoring complication to solve it immediately after operation is crucial to ensure donor safety and recovering successfully.

The aim of this paper is to review the current status of liver transplantation (LT) for Wilson disease (WD), focusing on indications and controversies, especially in patients with neuropsychiatric disease, and on identification of acute liver failure (ALF) cases related to WD. LT remains the treatment of choice for patients with ALF, as initial presentation of WD or when anti-copper agents are stopped, and for patients with chronic liver disease progressed to cirrhosis, unresponsive to chelating medications or not timely treated with copper chelating agents. The indication for LT in WD remains highly debated in patients with progressive neurological deterioration and failure to improve with appropriate medical treatment. In case of Wilsonian ALF, early identification is key as mortality is 100% without emergency LT. As many of the copper metabolism parameters are believed to be less reliable in ALF, simple biochemical tests have been proposed for diagnosis of acute WD with good sensitivity and specificity. LT corrects copper metabolism and complications resulting from WD with excellent 1 and 5 year survival. Living related liver transplantation represents an alternative to deceased donor LT with excellent long-term survival, without disease recurrence. Future options may include hepatocyte transplantation and gene therapy. Although both of these have shown promising results in animal models of WD, prospective human studies are much needed to demonstrate their long-term beneficial effects and their potential to replace the need for medical therapy and LT in patients with WD.

Hepatic gas gangrene is an uncommon situation mainly due to bacterial infection by Clostridium perfringens. It remains a life-threatening condition associated with a high mortality rate. Quick diagnosis and aggressive therapy including liver transplantation should be proposed to improve the outcome. This report describes a rare case of hepatic gas gangrene on native liver, secondary to iatrogenic hepatic artery thrombosis and instrumental biliary tree infection, which was successfully treated by liver transplantation.

The European Committee for Human Medicinal Products (CHMP) requested a multinational study with the aim to investigate the risk of acute liver failure (ALF) leading to registration for transplantation in patients exposed to non-steroidal anti-inflammatory drugs (NSAIDs). The method of this multinational, multicentre, retrospective case-population study, named SALT (Study of Acute Liver Transplant), is documented here. This was a multicentre, multinational retrospective case-population study performed in France, Italy, Portugal, Greece, Ireland, the Netherlands and the UK. The study period was 3 years (1 January 2005-31 December 2007). Cases were patients ≥ 18 years of age with ALF at the time of registration on the transplant list for liver transplantation who had been exposed to an NSAID within 30 days preceding the initial symptoms of liver disease (index date). Exposure was defined as exposure to any NSAID. Per country rates of NSAID-exposed transplantation-registered ALF were computed as the ratio of the number of cases identified in the country to total population exposure. Overall and per-drug sales for NSAIDs and for paracetamol were obtained from Intercontinental Marketing Services (IMS) Health for all participating countries. Population exposure was measured as the defined daily dose and as estimated annual number of patients exposed (primary endpoint) with 95 % confidence intervals. The study protocol was approved by the CHMP. Of the 57 eligible liver transplant centres, 54 agreed to participate in the study. All national authorizations were received with relevant administrative burden, mainly due to bureaucracy. The present study created a multinational research network to estimate population-based absolute rates of drug-exposed ALF leading to registration on the transplantation list. This study design was chosen to obtain a fast response to a public health issue, namely, that of an increased risk of a rare, very serious adverse reaction. This model

Cetuximab is a monoclonal antibody against epidermal growth factor receptor useful in the treatment of patients with Head and Neck Squamous Cell Carcinoma combined with radiotherapy or chemotherapy. Its pharmacokinetics are not influenced by hepatic status and there are no specific warnings concerning its indication in patients with impaired hepatic function. Patients with a previous liver transplant are at risk for hepatic toxicity and use immunosupressants to avoid rejection that can interact with other drugs. We present two cases of patients with a previous liver transplant in which cetuximab was administered to treat head and neck cancer.

Alcoholic liver disease (ALD) is the second most common diagnosis among patients undergoing liver transplantation (LT) in Europe and in the United States. The outcome of patients transplanted for ALD is at least as good as that for most other diagnoses and better than that for hepatitis C virus. In case of severe acute alcoholic hepatitis (AAH) non-responders to medical therapy, the reason for denying LT is that it requires abstinence from alcohol for six months before consideration for a transplant. A strict application of a period of abstinence as a policy for transplant eligibility is unfair to non-responder patients, as most of them will have died prior to the end of the six-month sober period. In our opinion, in severe AAH subjects with a good social support, with the frequency of self-help groups (alcoholics anonymous or association of clubs of alcoholics in treatment), with the frequency of Alcohol Unit and without severe psychotic or personality disorders, the lack of pre-LT abstinence alone should not be a barrier against being listed.

Hepatitis C virus (HCV) infection may be associated with extra-hepatic illness including mixed cryoglobulinemia (MC). Consistent evidence exists on HCV-MC in the non-transplantation setting but information on HCV-related cryoglobulinemia after solid organ transplantation is limited, particularly after liver transplantation (LT). We report on a 48-year-old man who developed HCV-associated cryoglobulinemic vasculitis with recurrent hepatitis after liver transplant. One year after transplant for HCV-positive cirrhosis, he presented severe cutaneous manifestations, and biopsy-proven cryoglobulinemic membrano-proliferative glomerulonephritis (MPGN). HCV RNA clearance occurred within a few weeks of antiviral therapy; sustained viral response (SVR) was obtained by one year of anti-HCV combination therapy (eight months of pegylated IFN/ribavirin and four months of standard IFN/ribavirin). SVR was linked to complete remission of skin, liver, and kidney abnormalities. Tolerance to the pegylated IFN/ribavirin regimen was not excellent due to the occurrence of lobar pneumonia with anemia; thus, peg-IFN was replaced by recombinant IFN, with a favorable outcome. Clinical and viral remission persisted over a 48-month follow-up. HCV-associated mixed cryoglobulinemia flareups following LT were successfully managed with combined antiviral therapy. HCV-related MC is uncommon in developed countries and this clearly hampers randomized controlled clinical trials aimed at evaluating the efficacy and safety of anti-HCV therapy after solid organ transplantation or in the non-transplantation setting.

Aim To evaluate the safety to donors of living-donor liver transplantation. Methods This study included 300 consecutive living liver tissue donors who underwent operations at our center from July 2002 to December 2012. We evaluated the safety of donors with regard to three aspects complications were recorded prospectively and stratified by grade according to Clavien’s classification, and the data were compared in two stages (the first 5 years’ experience (pre-January 2008) and the latter 5 years’ experience (post-January 2008); laboratory tests such as liver function and blood biochemistry were performed; and the health-related quality of life was evaluated. Results There was no donor mortality at our center, and the overall morbidity rate was 25.3%. Most of the complications of living donors were either grade I or II. There were significantly fewer complications in the latter period of our study than in the initial period (19.9% vs 32.6%, P<0.001), and biliary complications were the most common complications, with an incidence of 9%. All of the liver dysfunction was temporary; however, the post-operative suppression of platelet count lasted for years. Although within the normal range, eight years after operation, 22 donors showed lower platelet levels (189×109/L) compared with the pre-operative levels (267×109/L) (P<0.05). A total of 98.4% of donors had returned to their previous levels of social activity and work, and 99.2% of donors would donate again if it was required and feasible. With the exception of two donors who experienced grade III complications (whose recipients died) and a few cases of abdominal discomfort, fatigue, chronic pain and scar itching, none of the living donors were affected by physical problems. Conclusion With careful donor selection and specialized patient care, low morbidity rates and satisfactory long-term recovery can be achieved after hepatectomy for living-donor liver transplantation.

Following an overview of the data published in the specialized literature in connection with liver transplantation the author presents original experimental studies in this field. One of the first aspects considered is the stage of obtaining the graft of liver tissue. The selective perfusion was used, in situ, of the dog liver, and conditions were achieved which were similar to those obtained in other methods of graft preparation. Two washing solutions were used: a simple one, currently used in the practice, and another one which was enriched with various substrates. Biochemical parameters of tissue sampled by bioptic puncture have demonstrated that the first solution induces a lowering of the glycogen contents of hepatocytes, and this alters the biological qualities or the graft. The fact is stressed that the obtention of the hepatic tissue for grafting should be considered in fact as an in situ conservation. With regard to the liver transplantation proper it is shown that the author has performed the sector heterotopic procedure in the rat. Vascular anastomoses have been made with histoacryl-N-blau by the method of prosthesis with lost tubing. Problems raised by the vascular re-connection of the auxilliary hepatic tissue, and those related to the space where this tissue should be placed are also discussed in detail. The survival time was not longer than 30 hours.

We present a patient with lymphedema that developed after orthotopic liver transplantation. The cause of the posttransplant lymphedema was likely related to a developmental abnormality of the lymphatic system that was exaggerated by refractory chylous ascites. A peritoneal fluid with a milky appearance, chylous ascites is rich in triglyceride and is caused by the obstruction or disruption of abdominal lymphatic channels. It is a rare complication that may develop after trauma or abdominal surgery or as a result of a malignant disease, and it is even more uncommon after liver transplantation. Therapy for chylous ascites involves treating its underlying cause. In the patient we describe, lymphedema tarda, which was diagnosed 6 months after liver transplantation, was likely caused by chylous ascites and a developmental abnormality of the lymphatic system.

We report the outcome of liver transplantation (LT) in the only surviving patient with lathosterolosis, a defect of cholesterol biosynthesis characterized by high lathosterol levels associated with progressive cholestasis, multiple congenital anomalies and mental retardation. From her diagnosis at age 2 she had shown autistic behavior, was unable to walk unaided and her sight was impaired by cataracts. By age 7 she developed end-stage liver disease. After a soul-searching discussion within the transplantation team, she was treated with LT as this represented her only lifesaving option. At 1-year follow-up, her lathosterol levels had returned to normal (0.61 mg/dL from 13.04 ± 2.65) and her nutrition improved. She began exploring her environment and walking by holding onto an adult's hand and then independently. Her brain magnetic resonance imaging (MRI) had shown a normal picture at age 1, whereas a volume reduction of white matter with ex vacuo ventricular dilatation and defective myelinization were observed before transplant. At 5-year follow-up, a complete biochemical recovery, an arrest of mental deterioration and a stable MRI picture were achieved, with a return to her every day life albeit with limitations. Timely liver transplant in defects of cholesterol biosynthesis might arrest the progression of neurological damage. © Copyright 2014 The American Society of Transplantation and the American Society of Transplant Surgeons.

A 46-year-old man underwent living-donor liver transplantation and splenectomy for primary biliary cirrhosis. On postoperative day 22, cloudiness of ascites increased, and triglyceride concentration in ascites was as high as 1046 mg/dL. With a diagnosis of chylous ascites, total parenteral nutrition was started. Nine days after starting total parenteral nutrition, cloudiness of ascites decreased, and triglycerides in ascites decreased to 93 mg/dL. Oral intake was restarted, and the patient was discharged on postoperative day 46. Chylous ascites is a rare complication after living-donor liver transplantation for which total parenteral nutrition may be useful. PMID:23294080

One of the X chromosome-linked disorders is ornithine transcarbamylase deficiency in the urea cycle. This disorder results in increased ammonia and glutamine in the blood. Accumulation of these metabolites without treatment causes brain edema, which often progresses to coma and death. This study describes a 5-year-old girl with ornithine transcarbamylase deficiency who presented with hyperammonemic encephalopathy that was successfully treated with an orthotropic liver transplant. Recently, liver transplant has been introduced as an alternative treatment for patients with ornithine transcarbamylase deficiency.

Objective-To review all liver transplants performed at the American University of Beirut Medical Center from 1998 to present. Materials and Methods-From 1998 to present, 21 liver transplants (15 into adults and 6 into children) were performed at the American University of Beirut Medical Center. Of the 21 transplants, 5 were living related liver transplants. Results-Patient survival was 76% at 1, 5, and 10 years. Five recipients died at a median of 9 (range, 1-56) days after transplant. Causes of death included 1 case of severe cellular rejection, 1 case of portal and hepatic artery thrombosis, 1 case of intraoperative cardiac arrest, and 2 cases of primary nonfunction. Two biliary complications and 2 major vascular complications also occurred. All 16 survivors are well, with normal findings on liver function tests at a median follow-up time of 93 (range, 10-185) months after transplant. Conclusions-Although our numbers are small, the 10-year survival rate is comparable to reported rates for other series around the world. Deceased organ donations must be encouraged so that we can perform more transplants. As a source of organs, living related liver transplant is important; however, it cannot replace deceased donation.

The aim of our study was to evaluate our liver transplant pediatric patients and to report our experience in the complications and the long-term follow-up results. Patients between the ages of 0 and 18 years, who had liver transplantation in the organ transplantation center of our university hospital between 1997 and 2016, were included in the study. The age, sex, indications for the liver transplantation, complications after the transplantation, and long-term follow-up findings were retrospectively evaluated. The obtained results were analyzed with statistical methods. In our organ transplantation center, 62 pediatric liver transplantations were carried out since 1997. The mean age of our patients was 7.3 years (6.5 months-17 years). The 4 most common reasons for liver transplantation were: Wilson's disease (n=10; 16.3%), biliary atresia (n=9; 14.5%), progressive familial intrahepatic cholestasis (n=8; 12.9%), and cryptogenic cirrhosis (n=7; 11.3%). The mortality rate after transplantation was 19.6% (12 of the total 62 patients). The observed acute and chronic rejection rates were 34% and 4.9%, respectively. Thrombosis (9.6%) was observed in the hepatic artery (4.8%) and portal vein (4.8%). Bile leakage and biliary stricture rates were 31% and 11%, respectively. 1-year and 5-year survival rates of our patients were 87% and 84%, respectively. The morbidity and mortality rates in our organ transplantation center, regarding pediatric liver transplantations, are consistent with the literature.

Obesity is an important public health and medical concern in the United States. The rate of obesity has steadily risen for the past several decades. Obesity is associated with the development of nonalcoholic steatohepatitis, which is one of the leading indications for liver transplantation. After liver transplantation, recipients tend to gain weight and develop recurrent fatty liver. Over time, recurrent fatty liver may impact patient and graft survival. A bariatric surgical approach may be beneficial in select patients.

Neuroendocrine tumors (NET) are extremely rare in children (0.75 cases per 100,000 children and adolescents a year) and the majority of these tumors are benign or present low grade of malignancy. According to the American registry Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute, less than 2% of all neuroendocrine tumors in children occur in the pancreas, making it a rare site for these tumors. The majority of them are found in children over 10years of age, especially those with malignant potential. Treatment of NET consists of different methods: surgery, somatostatin analogues and chemotherapy. Radical surgical resection remains the standard of treatment; however, it is not always feasible because of distant metastases. The authors present a case report of pancreatic NET with multiple metastases to the liver. The patient was treated with pancreatic resection and liver transplantation for liver metastases. Prior to liver transplantation, the patient was treated with somatostatin analogues, sunitinib and chemotherapy. Management of liver metastases with liver transplantation is discussed.

Herpes simplex virus (HSV) hepatitis is an uncommon cause of liver failure, but may have a dramatic outcome. We herein present a case report of a liver graft infection by HSV-1 associated with liver failure and encephalitis. A complete hospital chart review of the case and a literature search were undertaken. Literature review suggests that herpes simplex acute liver failure is rare and associated with a poor prognosis, even with early treatment. Novel diagnostic and preventive approaches need to be instituted.

Hepatic venous outflow obstruction after piggyback liver transplantation is a very rare complication. An unusual mechanism aggravating it is reported. A 33-year-old man with end-stage hepatitis B liver cirrhosis underwent a piggyback orthotopic liver transplantation using a full-size cadaveric graft. Two months after transplantation, he developed gross ascites refractory to maximal diuretic therapy. Doppler ultrasound showed patent portal and hepatic veins. Serial computed tomography scans revealed a hypoperfused right posterior segment of the liver which subsequently underwent atrophy. Hepatic venography demonstrated a high-grade stenosis with an element of torsion of venous drainage at the anastomosis. The stenosis was successfully treated with repeated percutaneous balloon angioplasty. The patient remained asymptomatic six months afterwards with complete resolution of ascites and peripheral edema. We postulate that liver allograft segmental hypoperfusion and atrophy may aggravate or result in a hepatic venous outflow problem by the mechanism of torsion effect. Percutaneous balloon angioplasty is a safe and effective treatment modality for anastomotic stenosis. PMID:16981282

Alcoholic cirrhosis remains the second most common indication for liver transplantation. A comprehensive medical and psychosocial evaluation is needed when making a decision to place such patients on the transplant list. Most transplant centers worldwide need a minimum of 6 mo of alcohol abstinence for listing these patients. Patients with alcohol dependence are at high risk for relapse to alcohol use after transplantation (recidivism). These patients need to be identified and require alcohol rehabilitation treatment before transplantation. Recidivism to the level of harmful drinking is reported in about 15%-20% cases. Although, recurrent cirrhosis and graft loss from recidivism is rare, occurring in less than 5% of all alcoholic cirrhosis-related transplants, harmful drinking in the post-transplant period does impact the long-term outcome. The development of metabolic syndrome with cardiovascular events and de novo malignancy are important contributors to non liver-related mortality amongst transplants for alcoholic liver disease. Surveillance protocols for earlier detection of de novo malignancy are needed to improve the long-term outcome. The need for a minimum of 6 mo of abstinence before listing makes transplant a nonviable option for patients with severe alcoholic hepatitis who do not respond to corticosteroids. Emerging data from retrospective and prospective studies has challenged the 6 mo rule, and beneficial effects of liver transplantation have been reported in select patients with a first episode of severe alcoholic hepatitis who are unresponsive to steroids.

Radiology is a key specialty within a liver transplant program. Interventional techniques not only contribute to graft and recipient survival but also allow appropriate patient selection and ensure that recipients with severe liver decompensation, hepatocellular carcinoma or portal hypertension are transplanted with the best chance of prolonged survival. Equally inappropriate selection for these techniques may adversely affect survival. Liver transplantation is a dynamic field of innovative surgical techniques with a requirement for interventional radiology to parallel these developments. This paper reviews the current practice within a major European center for adult and pediatric transplantation.

In orthotopic liver transplantation, particular emphasis must be placed on the unique physiologic, pathologic, and clinical features in residents living in areas at high vs low altitude. Hypobaric hypoxia, hypothermia, heavy radiation, high wind speed, and superevaporation at high altitudes may lead to various diseases. These features have progressive effects on cardiopulmonary and central nervous system functions. A high concentration of red cells in the circulation is likely to result in an increased incidence of hepatic artery and portal vein thrombosis. The immune system is also affected at high altitudes. Exposure to high altitude, which is associated with decreased oxygen pressure, can result in oxidation-reduction stress, enhanced generation of reactive oxygen and nitrogen species, and related oxidative damage to lipids, proteins, and DNA. Our male patient with liver cirrhosis caused by chronic hepatitis B virus infectionunderwent orthotopic liver transplantation in Tibet with a successful outcome and good long-term survival.

Opportunistic infections are a leading cause of morbidity and mortality after orthotopic liver transplantation. Systemic immunosuppression renders the liver recipient susceptible to de novo infection with bacteria, viruses and fungi post-transplantation as well to reactivation of pre-existing, latent disease. Pathogens are also transmissible via the donor organ. The time from transplantation and degree of immunosuppression may guide the differential diagnosis of potential infectious agents. However, typical systemic signs and symptoms of infection are often absent or blunted after transplant and a high index of suspicion is needed. Invasive procedures are often required to procure tissue for culture and guide antimicrobial therapy. Antimicrobial prophylaxis reduces the incidence of opportunistic infections and is routinely employed in the care of patients after liver transplant. In this review, we survey common bacterial, fungal, and viral infections after orthotopic liver transplantation and highlight recent developments in their diagnosis and management. PMID:25755581

Low case volume has been associated with poorer surgical outcomes in a multitude of surgical procedures. We studied the association among low case volume, outcomes, and the likelihood of pediatric liver transplantation. We studied a cohort of 6628 candidates listed in the Organ Procurement and Transplantation Network for primary pediatric liver transplantation between 2002 and 2012; 4532 of the candidates went on to transplantation. Candidates were divided into groups according to the average volume of yearly transplants performed in the listing center over 10 years: >15, 10 to 15, 5 to 9, and <5. We used univariate and multivariate Cox regression analyses with bootstrapping on transplant recipient data and identified independent recipient and donor risk factors for wait-list and posttransplant mortality. 38.5% of the candidates were listed in low-volume centers, those in which <5 transplants were performed annually. These candidates had severely reduced likelihood of transplantation with only 41% receiving a transplant. For the remaining candidates, listed at higher volume centers, the transplant rate was 85% (P < .001). Being listed at a low-volume center was a significant risk factor in multivariate Cox regression analysis for both wait-list mortality (hazard ratio, 3.27; confidence interval, 2.53-4.23) and posttransplant mortality (hazard ratio, 2.21; confidence interval, 1.43-3.40). 38.5% of pediatric transplant candidates are listed in low-volume transplant centers and have lower likelihood of transplantation and poorer outcomes. If further studies substantiated these findings, we would advocate consolidating pediatric liver transplantation in higher volume centers. Copyright © 2015 by the American Academy of Pediatrics.

Arthrogryposis-renal tubular dysfunction-cholestasis syndrome (MIM No. 208085) is a rare multisystem disorder involving the liver, kidney, skin, and central nervous and musculoskeletal systems. The syndrome is an autosomal-recessive trait, associated with germ-line mutations in the VPS33B gene. We report an Iranian boy of consanguineous cousin parents who had congenital deformities of the upper and lower extremities, severe ichthyosis, cholestasis, intractable pruritus, metabolic acidosis, and failure to thrive. Owing to cholestasis, severe intractable pruritus, and poor quality of life, he underwent a living-related liver transplant from his mother, and his ichthyosis and pruritus dramatically improved. To the best of our knowledge, this is a first case of someone with arthrogryposis-renal tubular dysfunction-cholestasis syndrome who underwent a liver transplant and is in good condition more than 5 years after surgery.

BACKGROUND Cardiopulmonary (CP) outcomes remain a leading cause of morbidity and mortality following liver transplantation (LT). The optimal CP risk stratification of LT candidates remains unclear. The aim of this study was to evaluate the association of pre-LT transthoracic echocardiogram (TTE) findings and 6-month post-LT outcomes. MATERIAL AND METHODS This retrospective review analyzed adults who underwent LT, comparing those who died within 6 months of LT (cases; n=38) with age- and sex-matched patients who survived >6 months (controls; n=38). Cases were categorized by cause of death (COD) defined as either a primary CP process (n=20) or a non-CP process (n=18). Data were analyzed using logistic regression and survival analysis was performed using Kaplan-Meier curves. RESULTS There was a higher odds of death within 6 months of LT with ≥ mild mitral regurgitation (OR 3.44, p=0.03) or an incomplete assessment of right ventricular systolic function (RVSF) (OR 24, p=0.004). On subgroup analysis, these findings only persisted in patients with a CP COD. Patients with CP COD were older (61 vs. 54.5, p=0.04), had longer intervals between TTE and LT (122 vs. 29 days, p=0.05), less complete assessments of RVSF (p=0.009), and lower RV fractional area change (p=0.04) compared to patients with non-CP COD. CONCLUSIONS Multiple TTE parameters were associated with patients who died within 6 months of LT, and in particular patients with a CP COD. Our findings suggest that pre-LT TTEs can convey useful CP risk stratification information and emphasizes the importance of adequately assessing these parameters prior to LT.

In the year 2000, at the Department for General Surgery and Liver Transplantation from The Fundeni Clinical Institute Bucharest, seven OLTs and one living-related transplantation were performed in 6 adults and 2 children. Postoperative complications were: bile leakage, hemoperitoneum, lower gastrointestinal hemorrhage, parietoabdominal hematoma. There was only one postoperative death due to septic complications in the 18th p.o.d. and one late death due to pneumonia of unknown origin. After the results in the year 2000 there was an increased number of donors and referrals. We consider that now in Romania this is an established program that will continue depending on the number of donors and financing.

Development of organ transplantation is restricted by the discrepancy between the lack of donors and increasing number of patients. The outcome of pediatric donors transplanted into adult recipients especially with donation after circulatory death (DCD) pattern has not been well studied. The aim of this paper is to describe our experience of 3 successful DCD donor child-to-adult liver transplantations lately. Three DCD donors were separately 7, 5, and 8 years old. The ratio between donor graft weight and recipient body weight was 1.42%, 1.00%, and 1.33%, respectively. Ratio between the volume of donor liver and the expected liver volume was 0.65, 0.46, and 0.60. Splenectomy was undertaken for the second recipient according to the portal vein pressure (PVP) which was observed during the operation. Two out of 3 of the recipients suffered with acute kidney injury and got recovered after renal replacement therapy. The first recipient also went through early allograft dysfunction and upper gastrointestinal bleeding. The hospital course of the third recipient was uneventful. After 1 year of follow-up visit, the first and second recipients maintain good quality of life and liver function. The third patient was followed up for 5 months until now and recovered well. DCD child-to-adult liver transplantation should only be used for comparatively matched donor and recipient. PVP should be monitored during the operation. The short-term efficacy is good, but long-term follow-up and clinical study with large sample evaluation are still needed.

Cholestatic liver diseases include a group of diverse disorders with different epidemiology, pathophysiology, clinical course, and prognosis. Despite significant advances in the clinical care of patients with cholestatic liver diseases, liver transplant (LT) remains the only definitive therapy for end-stage liver disease, regardless of the underlying cause. As per the United Network for Organ Sharing database, the rate of cadaveric LT for cholestatic liver disease was 18% in 1991, 10% in 2000, and 7.8% in 2008. This review summarizes the available evidence on various common and rare cholestatic liver diseases, disease-specific issues, and pertinent aspects of LT.

The so-called piggyback technique of liver transplantation (PB-LT) preserves the recipient's caval vein, shortening the warm ischemic time. It can be reduced even further by using a linear stapler for the cavocaval anastomosis. Herein, we have presented a case of a patient undergoing a side-to-side, whole-organ PB-LT for cryptogenic cirrhosis. Upper and lower orifices of the donor caval vein were closed at the back table using a running 5-0 polypropylene suture. Three stay sutures were then placed on caudal parts of both the recipient and donor caval with a 5-mm venotomies. The endoscopic linear stapler was placed upward through the orifices and fired. A second stapler was placed more cranially and fired resulting in a 8-9 cm long cavocavostomy. Some loose clips were flushed away from the caval lumen. The caval anastomosis was performed within 4 minutes; the time needed to close the caval vein stapler insertion orifices (4-0 polypropylene running suture) before reperfusion was 1 minute. All other anastomoses were performed as typically sutured. The presented technique enables one to reduce the warm ischemic time, which can be of particular importance with marginal grafts.

Size mismatch is an unique and inevitable but critical issue in live donor liver transplantation. Unmatched metabolic demand of recipient as well as physiologic mismatch aggravates the damage to liver graft, inevitably leading to graft failure on recipient. Also, an excessive resection of liver graft for better recipient outcome in live donor liver transplant may jeopardize the healthy donor well-being and even put donor life in danger. There is a fine balance between resected graft volume required to meet the recipient's metabolic demand and residual graft volume required for donor safety. The obvious clinical necessity of finding that balance has prompted a clinical need and promoted the improvement of knowledge and development of management strategies for size-mismatched transplants. The development of the size-matching methodology has significantly improved graft outcome and recipient survival in live donor liver transplants. On the other hand, the effect of size mismatch in cadaveric transplants has never been observed as being so pronounced. The importance of matching of the donor recipient size has been unrecognized in cadaveric liver transplant. In this review, we attempt to summarize the current most updated knowledge on the subject, particularly addressing the definition and complications of size-mismatched cadaveric liver transplant, as well as management strategies. © 2016 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

A 66-year-old female who had undergone an orthotopic liver transplant two years before admission was admitted with fever and neurological symptoms of several days' duration. Following an extensive work-up, which revealed positive intracranial lesions on computed typography and magnetic resonance imaging, the patient was begun on broad spectrum antimicrobials including corticosteroids. The patient responded though the etiology of infection remained unclear. After a stereotactic biopsy was performed revealing granulomas and acid-fast bacilli, the patient was started on antituberculous medications. A review of the literature reveals that the rare occurrence of intracranial tuberculoma should be considered in an orthotopic liver transplant (OLT) patient with central nervous system pathology.

Liver transplantation as a specific treatment of transthyretin amyloidosis was first performed in 1990. The rationale for this treatment was that removal of the source (liver) of the amyloid precursor protein (mutated transthyretin) would stop progression of the disease. Indeed, after orthotopic liver transplantation (OLT), mutant transthyretin (TTR) is rapidly cleared from circulation. In the last 20 years, >2000 familial amyloidotic polyneuropathy (FAP) patients have received liver transplants. For these patients, prospective monitoring has shown prolongation of life compared with FAP patients who have not undergone liver transplantation. The most favorable results have been for FAP patients with the Val30Met TTR mutation. Less favorable results have been seen for patients with other TTR mutations where progression of amyloid tissue deposition has been documented as the result of amyloid fibril formation from normal (wild-type) TTR. Although it is obvious that OLT has benefited many FAP patients, there remains a need for further therapies. Copyright © 2012 Wiley Periodicals, Inc.

Background—Uncertainty exists about the extent and consequences of a return to alcohol consumption after liver transplantation for alcoholic liver disease (ALD). Aims—To determine the prevalence and consequences of alcohol consumption in patients transplanted for ALD. Methods—A retrospective case controlled study of all patients transplanted for ALD at the Queen Elizabeth Hospital, Birmingham, between 1987 and 1996. Results—Seventy patients with ALD were transplanted, of which 59 survived more than three months; 56 were interviewed. Twenty eight had consumed some alcohol after transplantation; for the nine "heavy drinkers" (HD), the median time to resumption of alcohol intake was six months and for the 19 "moderate drinkers" (MD) it was eight months. There was no significant difference in episodes of acute rejection or compliance with medication between those who were abstinent, MD, or HD. Histological evidence of liver injury was common in ALD patients who had returned to drink. Mild fatty change was found in 1/11 biopsy specimens from abstinent patients but moderate to severe fatty change and ballooned hepatocytes were seen in 3/5 MD and 2/5 HD specimens. Two HD patients had early fibrosis. One HD patient has died of alcohol related complications. Conclusions—Moderate to heavy alcohol consumption occurs in patients transplanted for ALD. Patient recall of abstinence advice is unreliable, and patients return to alcohol mainly within the first year after liver transplantation. Return to alcohol consumption after liver transplantation is associated with rapid development of histological liver injury including fibrosis.

Objective: The aim of our study was to evaluate our liver transplant pediatric patients and to report our experience in the complications and the long-term follow-up results. Materials and Methods: Patients between the ages of 0 and 18 years, who had liver transplantation in the organ transplantation center of our university hospital between 1997 and 2016, were included in the study. The age, sex, indications for the liver transplantation, complications after the transplantation, and long-term follow-up findings were retrospectively evaluated. The obtained results were analyzed with statistical methods. Results: In our organ transplantation center, 62 pediatric liver transplantations were carried out since 1997. The mean age of our patients was 7.3 years (6.5 months–17 years). The 4 most common reasons for liver transplantation were: Wilson’s disease (n=10; 16.3%), biliary atresia (n=9; 14.5%), progressive familial intrahepatic cholestasis (n=8; 12.9%), and cryptogenic cirrhosis (n=7; 11.3%). The mortality rate after transplantation was 19.6% (12 of the total 62 patients). The observed acute and chronic rejection rates were 34% and 4.9%, respectively. Thrombosis (9.6%) was observed in the hepatic artery (4.8%) and portal vein (4.8%). Bile leakage and biliary stricture rates were 31% and 11%, respectively. 1-year and 5-year survival rates of our patients were 87% and 84%, respectively. Conclusion: The morbidity and mortality rates in our organ transplantation center, regarding pediatric liver transplantations, are consistent with the literature. PMID:28149148

Chronic liver disease has a profound effect on nutritional status and undernourishment is almost universally present in patients with end-stage liver disease undergoing liver transplantation. In the last decades, due to epidemiological changes, a trend showing an increase in patients with end-stage liver disease and associated obesity has also been reported in developed countries. Nutrition abnormalities may influence the outcome after transplantation therefore, the importance to carefully assess the nutritional status in the work-up of patients candidates for liver transplantation is widely accepted. More attention has been given to malnourished patients as they represent the greater number. The subjective global nutritional assessment and anthropometric measurements are recognized in current guidelines to be adequate in identifying those patients at risk of malnutrition. Cirrhotic patients with a depletion in lean body mass and fat deposits have an increased surgical risk and malnutrition may impact on morbidity, mortality and costs in the post-transplantation setting. For this reason an adequate calorie and protein intake should always be ensured to malnourished cirrhotic patient either through the diet, or using oral nutritional supplements or by enteral or parenteral nutrition although studies supporting the efficacy of nutritional supplementation in improving the clinical outcomes after transplantation are still scarce. When liver function is restored, an amelioration in the nutritional status is expected. After liver transplantation in fact dietary intake rapidly normalizes and fat mass is progressively regained while the recovery of muscle mass can be slower. In some patients unregulated weight gain may lead to over-nutrition and may favor metabolic disorders (hypertension, hyperglycemia, hyperlipidemia). This condition, defined as 'metabolic syndrome', may play a negative role on the overall survival of liver transplant patients. In this report we review
Hepatic hemangioma patients with Kasabach-Merritt syndrome have reportedly been cured by liver transplantation. However, liver transplantation as a potential cure for a stable patient without Kasabach-Merritt syndrome remains debatable. We report the case of a 27-year-old female patient with a giant hepatic hemangioma. The hemangioma measured 50 × 40 × 25 cm in size and weighed 15 kg, which is the largest and heaviest hemangioma reported in the literature. The patient showed jaundice, ascites, anemia, and appetite loss; but no disseminated intravascular coagulation was observed through laboratory findings. We successfully operated using a right lobe graft without the middle hepatic vein from a 55-year-old donor. At the long-term follow-up, the patient experienced two acute rejections, which were confirmed by biopsy. However, the patient still survives with good graft function after 50 months. PMID:24708716

Summary Acute liver failure (ALF) is defined by the presence of coagulopathy (International Normalized Ratio ≥ 1.5) and hepatic encephalopathy due to severe liver damage in patients without pre-existing liver disease. Although the mortality due to ALF without liver transplantation is over 80%, the survival rates of patients have considerably improved with the advent of liver transplantation, up to 60% to 90% in the last two decades. Recent large studies in Western countries reported 1, 5, and 10-year patient survival rates after liver transplantation for ALF of approximately 80%, 70%, and 65%, respectively. Living donor liver transplantation (LDLT), which has mainly evolved in Asian countries where organ availability from deceased donors is extremely scarce, has also improved the survival rate of ALF patients in these regions. According to recent reports, the overall survival rate of adult ALF patients who underwent LDLT ranges from 60% to 90%. Although there is still controversy regarding the graft type, optimal graft volume, and ethical issues, LDLT has become an established treatment option for ALF in areas where the use of deceased donor organs is severely restricted.

Living donor liver transplantation has emerged as a response to the cadaveric graft shortage, especially for adult recipients. Both right and left liver grafts are widely used, although some technical problems remain unresolved. Herein we describe our technique for reconstruction of the venous outflow in living donor liver transplantation. From April 1986 to September 2004, 1012 liver transplantations were performed including 30 living donor liver transplantations between April 1995 and September 2004. We have selected the first 28 cases to ensure a mean follow-up of 21.07 +/- 13.11 months. We transplanted 18 right lobe grafts, 7 left lobe grafts, and 3 left lateral segment grafts. A surgical technique is described herein. No venous outflow obstruction developed among living donor liver transplantation recipients. We recommend reconstruction of the hepatic veins in living donor liver transplantation including joining together the three hepatic veins in the recipient to avoid venous outflow obstruction.

Thrombotic microangiopathy (TMA) is a potentially fatal complication in solid organ and bone marrow transplant patients, with reported incidence of 0.5-3% and mortality of about 75%. To emphasise the importance of early diagnosis and prompt commencement of therapy results in improved clinical outcomes. A retrospective study of all patients who underwent orthotopic liver transplantation (OLTX) at the Western Australian Liver Transplantation Service from May 1994 to December 2010 was conducted to identify patients who developed tacrolimus-induced TMA. We identified four patients with tacrolimus-induced TMA post-OLTX, derived from a cohort of 104 patients treated with tacrolimus in our institution. The mean age at diagnosis was 40 years, and the mean time of onset was 63 ± 7.5 weeks after OLTX. The indications for OLTX in the four patients were fulminant hepatic failure in three (Wilson disease, paracetamol overdose and post-partum thrombotic thrombocytopenic purpura) and hepatitis C virus-related cirrhosis. All patients had tacrolimus post-OLTX. At diagnosis, tacrolimus was discontinued in all patients, and three of the four patients underwent plasma exchange and all patients improved clinically. Mean duration of follow up was 15 ± 7.5 months. There was no mortality 6 months post-TMA. Early diagnosis with immediate discontinuation or conversion of calcineurin inhibitors and plasma exchange should be offered to OLTX patients with TMA as it results in good outcomes. © 2013 The Authors; Internal Medicine Journal © 2013 Royal Australasian College of Physicians.

Hyperlipidemia is very common after liver transplantation and can be observed in up to 71% of patients. The etiology of lipid disorders in these patients is multifactorial, with different lipid profiles observed depending on the immunosuppressive agents administered and the presence of additional risk factors, such as obesity, diabetes mellitus and nutrition. Due to recent improvements in survival of liver transplant recipients, the prevention of cardiovascular events has become more important, especially as approximately 64% of liver transplant recipients present with an increased risk of cardiovascular events. Management of dyslipidemia and of other modifiable cardiovascular risk factors, such as hypertension, diabetes and smoking, has therefore become essential in these patients. Treatment of hyperlipidemia after liver transplantation consists of life style modification, modifying the dose or type of immunosuppressive agents and use of lipid lowering agents. At the start of administration of lipid lowering medications, it is important to monitor drug-drug interactions, especially between lipid lowering agents and immunosuppressive drugs. Furthermore, as combinations of various lipid lowering drugs can lead to severe side effects, such as myopathies and rhabdomyolysis, these combinations should therefore be avoided. To our knowledge, there are no current guidelines targeting the management of lipid metabolism disorders in liver transplant recipients. This paper therefore recommends an approach of managing lipid abnormalities occurring after liver transplantation. PMID:27022213

Chronic hepatitis C virus (HCV) is a worldwide health problem. Approximately 4 million people in the United States are chronically infected with HCV. The incidence of infection peaked between 2 and 3 decades ago, and we are now beginning to see an increase in the complications of cirrhosis from HCV. This trend is expected to continue for another 2 to 3 decades. Survival is poor once complications of cirrhosis, such as liver failure or hepatocellular carcinoma, ensue, and liver transplantation is often the only option. Complications of chronic HCV are the most common indication for liver transplantation, accounting for more than 40% of transplants performed in the United States and Europe. HCV recurs in all patients and rapid development of hepatic fibrosis is very common. Several strategies have been proposed to reduce the risk of graft loss from recurrent HCV infection after transplantation, as the progression of the resulting liver disease is rapid. Although antiviral treatment is successful in some patients, it is extremely difficult to administer and requires dose reductions in the majority of cases. Retransplantation in the current era of the Model for End-Stage Liver Disease (MELD) system for prioritizing listing for transplant is associated with very low survival rates at a high cost. Furthermore, the system raises difficult ethical issues of utilization of limited resources and fairness to other transplant candidates.

Infections occurring in liver transplant recipients result in significant morbidity and mortality. Factors influencing the frequency of posttransplant infections include pretransplant nutritional status, latent viral infections, and the degree of immunosuppression used to modulate the immune response to the allograft. Infectious agents may be introduced into the patient via the allograft, through infusion of blood products, and through intravenous lines, catheters, and drains. Infections also develop as a result of reactivation of latent viruses or by overgrowth or invasion by endogenous organisms. The intensity of the immunosuppressive regimen directly affects the frequency of infection. Infection may be categorized as bacterial, viral, fungal, or protozoal. The most frequent organisms include bacterial--enterobacteriaceae; viral--cytomegalovirus; fungal--Candida species and Aspergillus species; and protozoal--Pneumocystis carinii. Diagnosing infection requires the use of many different methods in combination, including routine bacterial culture, viral culture, and fungal culture. Histologic and cytologic examination may lead to rapid identification of some organisms. Specialized collection procedures such as bronchoalveolar lavage provide rapid access to material for culture and cytologic examination. Serum serology in conjunction with histotopic or cytologic evaluation is useful in diagnosing some infections, such as Epstein-Barr virus. New technology such as polymerase chain reaction allows detection of all types of infection at or before the onset of clinical symptoms. Rapid and early diagnosis of infection in this patient population can reduce infection-related morbidity and mortality.

Liver transplantation is a life-saving therapy to correct liver failure, portal hypertension and hepatocellular carcinoma arising from hepatitis C infection. But despite the successful use of living donors and improvements in immunosuppression and antiviral therapy, organ demand continues to outstrip supply and recurrent hepatitis C with accelerated progression to cirrhosis of the graft is a frequent cause of graft loss and the need for retransplantation. Appropriate selection of candidates and timing of transplantation, coupled with better pre- and post-transplant antiviral therapy, are needed to improve outcomes.

Scedosporium spp. are saprobic fungi that cause serious infections in immunocompromised hosts and in near-drowning victims. Solid organ transplant recipients are at increased risk of scedosporiosis as they require aggressive immunosuppression to prevent allograft rejection. We present a case of disseminated Scedosporium apiospermum infection occurring in the recipient of a combined kidney and liver transplantation whose organs were donated by a near-drowning victim and review the literature of scedosporiosis in solid organ transplantation.

Effective use of all available donated organs is critical, in order to meet the increasing demand for transplants. The present study explored liver transplantation with livers that were donated following cardiac death (DCD). According to the guidelines established by The Red Cross Society of China, 42 DCD organs were procured. Selected donors were treated with extracorporeal membrane oxygenation (ECMO) prior to the organ retrieval. The present single-center study included 6 liver transplantations of DCD organs (5 liver transplants and 1 liver-kidney combined transplant). All 6 recipients had a successful recovery without significant complications. The serum alanine transaminase, total bilirubin and international normalized ratio returned to the normal levels within a short period of time following transplantation, and the liver function remained normal during the follow-up period, which lasted up to 24 months. The present report demonstrated the feasibility of orthotopic liver transplantation using DCD livers. The pre-conditioning DCD donors and optimization of the recipient's condition using ECMO, played a crucial role in ensuring the success of transplantation. PMID:26998025

Background : Appendicitis is a common cause of emergency surgery that in the population undergoing organ transplantation presents a rare incidence due to late diagnosis and treatment. Aim : To report the occurrence of acute appendicitis in a cohort of liver transplant recipients. Methods : Retrospective analysis in a period of 12 years among 925 liver transplants, in witch five cases of acute appendicitis were encountered. Results : Appendicitis occurred between three and 46 months after liver transplantation. The age ranged between 15 and 58 years. There were three men and two women. The clinical presentations varied, but not discordant from those found in non-transplanted patients. Pain was a symptom found in all patients, in two cases well located in the right iliac fossa (40%). Two patients had symptoms characteristic of peritoneal irritation (40%) and one patient had abdominal distention (20%). All patients were submitted to laparotomies. In 20% there were no complications. In 80% was performed appendectomy complicated by suppuration (40%) or perforation (40%). Superficial infection of the surgical site occurred in two patients, requiring clinical management. The hospital stay ranged from 48 h to 45 days. Conclusion : Acute appendicitis after liver transplantation is a rare event being associated with a high rate of drilling, due to delays in diagnosis and therapy, and an increase in hospital stay.

Coagulation monitoring during liver transplantation (LT) is, even today, fundamental to reduce blood loss during surgery. Thromboelastometry (TEM) is a proven technique for controlling the various parameters that influence coagulation. However, there are no studies linking "intra-operating room" TEM (orTEM) with LT outcomes. We describe a case-control study in 303 liver graft recipients analyzing variables associated with operative complications and long-term LT outcomes. The results showed that orTEM reduced the use of blood products in patients with Model for End-Stage Liver Disease scores of ≥ 21, retransplantation, and high surgical difficulty and important intraoperative bleeding. In addition, results in survival and postoperative complications were better when orTEM was used. In conclusion, we confirm that use of orTEM is associated with less use of blood products and a lower rate of complications after LT.

Liver transplantation (LT) has evolved rapidly since the first successful liver transplant performed in1967. Despite a humble beginning, this procedure gained widespread acceptance in the western world as a suitable option for patients with end stage liver disease (ESLD) by the beginning of the 1980s. At present, approximately 25,000 liver transplants are being performed worldwide every year with approximately 90% one year survival. The techniques of living donor liver transplantation (LDLT) developed in East Asia in the 1990s to overcome the shortage of suitable grafts for children and scarcity of deceased donors. While deceased donor liver transplantation (DDLT) constitutes more than 90% of LT in the western world, in India and other Asian countries, most transplants are LDLT. Despite the initial disparity, outcomes following LDLT in eastern countries have been quite satisfactory when compared to the western programs. The etiologies of liver failure requiring LT vary in different parts of the world. The commonest etiology for acute liver failure (ALF) leading to LT is drugs in the west and acute viral hepatitis in Asia. The most common indication for LT due to ESLD in west is alcoholic cirrhosis and hepatitis C virus (HCV), while hepatitis B virus (HBV) predominates in the east. There is a variation in prognostic models for assessing candidature and prioritizing organ allocation across the world. Model for end–stage liver disease (MELD) is followed in United States and some European centers. Other European countries rely on the Child–Turcotte–Pugh (CTP) score. Some parts of Asia still follow chronological order of listing. The debate regarding the best model for organ allocation is far from over. PMID:25755506

Liver transplantation is an option that improves quality of life and prolongs life expectancy in patients with different types of liver disease. Liver transplantation is controversial for colorectal metastases and is not recommended in clinical practice guidelines. In this case report, we present, to our knowledge, the first liver transplantation for colorectal metastases conducted in Colombia, with a successful follow-up of more than 2 years. Patients with these characteristics who underwent liver transplantation experience reduced mortality and exponentially improved quality of life. PMID:28203128

Glycogen storage disease type Ia (GSD-Ia; also termed von Gierke disease) is an inherited metabolic disorder resulting from a glucose-6-phosphatase deficiency. Liver transplantation is considered to be the most effective treatment for GSD-Ia patients. In the present study, the case of a patient with GSD-Ia who received a liver transplantation at 17 years of age is presented. During the 12 years following transplantation, the patient's quality of life markedly improved. However, recently, the patient was diagnosed with de novo gastric cancer following a biopsy. Thus, a total gastrectomy with lymph node dissection was performed and the tumor was histologically determined to be a poorly differentiated adenocarcinoma (histopathological stage, pT4N1M0). The patient recovered well and was discharged on postoperative day 10 without any complications. To the best of our knowledge, this is the first case of de novo gastric cancer in a patient with GSD-Ia to be reported.

We report a case of a 51-year-old man who received a cadaveric liver allograft for autoimmune and hepatopulmonary syndrome. The patient was admitted with symptoms of progressive vomiting and diarrhea 16 months after transplantation. Laboratory studies showed abnormal liver functions, and abdominal magnetic resonance imaging (MRI) showed a 76-mm heterogeneous mass in the liver. Histological examination showed a malignant lymphoid neoplasm with plasmablastic features. Plasmablastic lymphoma (PL) is rare in the post-transplantation period. To the best of our knowledge, only 25 well-documented cases of posttransplant PL, including ours, have been described.
Patients with hepatic failure and liver-based metabolic disorders require management which is both costly and complex. Hepatocyte transplantation has been very encouraging as an alternative to organ transplantation for liver disease treatment, and studies in rodents, show that transplants involving isolated liver cells can reverse hepatic failure, and correct various metabolic deficiencies of the liver. This 2016 review is based on a literature search using PubMed including original articles, reviews, cases and clinical guidelines. The search terms were “hepatocyte transplantation”, “liver transplantation”, “liver cell failure”, “metabolic liver disorders”, “orthotropic liver transplantation”, “hepatocytes” and “stem cell transplantation”. The goal of this review is to summarize the significance of hepatocyte transplantation, the sources of hepatocytes and the barriers of hepatocyte transplantation using a detailed review of literature. Our review shows that treatment of patients with liver disease by hepatocyte transplantation has expanded exponentially, especially for patients suffering from liver-based metabolic disorders. Once hepatocyte transplantation has been shown to effectively replace organ transplantation for a portion of patients with life-threatening liver metabolic diseases and those with liver failure it will make cell therapy effective and available for a broad population of patients with liver disorders.

Pregnancy after liver transplantation is possible but associated with increased risk of obstetrical complications. We report here for the first time the pregnancy outcomes after liver transplantation in Finland. All of the 25 pregnancies ending in deliveries after liver transplantation in Finland in 1998-2015 were analyzed. The data were collected from the mothers' medical records. The main outcome measures included pregnancy complications and the mode of delivery. Neonatal outcome measures were birthweight, 5-min Apgar score and umbilical artery pH. Twenty-six infants were born. Of all deliveries, 76% occurred at the ≥37 weeks of gestation and the average birthweight was 3040 g. Apgar scores were ≥7 in 25/26 (96%) of the infants and cases of birth asphyxia (umbilical artery pH ≤ 7.05) were not detected. Cesarean section rate was 32%. Preeclampsia occurred in 12% of the women and the preterm delivery rate was 24%. Co-morbidities (hypertension, intrahepatic cholestasis of pregnancy, Hodgkin's disease, colitis ulcerosa, epileptic attacks, cholangitis, splenic artery rupture, renal insufficiency and graft rejection) complicated 52% of pregnancies. Pregnancies after liver transplantation in Finland result in good perinatal outcome with healthy, mostly full-term, normally grown offspring; however, serious maternal complications related to underlying liver pathology, transplant surgery and immunosuppressive medication occur frequently. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

Liver transplantation is the definitive treatment for end-stage liver diseases. The first successful liver transplant was performed in the United States by Thomas Starzl in 1967. The first successful solid organ transplant in Turkey was a living-related kidney transplant performed by Dr. Haberal in 1975. After much effort by Dr. Haberal, the Turkish parliament enacted a law about organ transplantation in 1979. After clinical and experimental studies, the first liver transplant in Turkey was performed by Dr. Haberal in 1988. The first successful partial living-donor liver transplant in children in Turkey was performed by the same team on March 15, 1990. On April 24, 1990, the first living-donor liver transplant was performed on a child in Turkey using a left lateral segment by Dr. Haberal and coworkers. On May 16, 1992, Dr. Haberal performed a simultaneous living-donor liver and kidney transplantation to an adult from the same donor. There currently are 30 liver transplantation centers in Turkey. According to data from the Ministry of Health, there presently are 2065 patients in Turkey who are waiting for a liver transplantation. From January 2002 to June 2013, there were 6091 liver transplants performed in Turkey (4020 living-donor [66% ] and 2071 deceased donor liver transplants [34% ]). From January 2011 to June 2013, there were 2514 patients who had liver transplants in Turkey, and 437 patients (17%) died. The number of liver transplants per year in Turkey reached 1000 transplants in 2012 and more than 1150 transplants in 2013 (15.1/million/y). Therefore, Turkey has one of the highest volumes of liver transplantation per population worldwide, with 90% survival within 1 year after transplantation.

Although donor-specific antibodies are regarded as a contraindication for kidney transplantation, the data available for combined liver and kidney transplantation (cLKTx) are scarce, and there is no established therapeutic approach for this category of transplant recipients. De novo use of everolimus and a reduced dose of calcineurin inhibitor reportedly provides excellent kidney function compared with a standard regimen containing a calcineurin inhibitor. This strategy, however, has been applied in only some recipient categories. Here we report a case of A highly sensitized male patient who underwent a cLKTx and received everolimus with low-dose tacrolimus (once-daily prolonged-release formulation) as ab initio immunosuppressive treatment. The pretransplant panel-reactive antibody estimate was 97%, and multiple anti-HLA antibodies were detected at the time of transplantation. Thus far, patient and allograft survival have reached 2 years, with the recipient remaining on a regimen of immunosuppression with everolimus and low-dose tacrolimus, with no episodes of rejection.

Hernias after orthotopic liver transplant (OLT) occur in about 30 % of cases. Predisposing factors in liver cirrhotic patients of cases are ascites, low abdominal muscle mass and cachexia before and immunosuppression after OLT. Standard operative transplant-technique even in small hernias is to implant a mesh. For patients after liver transplantation a porcine non-cross linked biological patch being less immunogenic than synthetic and cross-linked meshes is chosen for ventral incisional hernia repair. 3 patients (1 female, 2 male), OLT indications Hepatitis C, exogenous- toxic cirrhosis, median-age 53 (51 - 56) and median time to hernia occurrence after OLT were 10 month (6 - 18 m) are documented. 2 patients suffered from diabetes, 2 from chronic-obstructive lung disease. Maintenance immunosuppressions were Everolimus in 1 patient, Everolimus + MMF in the second and Everolimus +Tacrolimus in the third patient. The biological was chosen for hernia repair due to the preexisting risk- factors. Meshes, 10 × 16 cm were placed, in IPOM (Intra-Peritonel-Onlay-Mesh) -position by relaparatomy. Insolvable, monofile, interrupted sutures were used. All patients recovered primarily, and were dismissed within 10 d post OP. No wound healing disorders or signs of postoperative infections occurred. All are free of hernia recurrence in a mean observation time of 22 month (10 - 36). The usage of porcine non-cross-linked biological patches seems feasible for incisional hernia repair after OLT. Wound infections in these patients have been observed with other meshes. Further investigation is needed to prove potential superiority of this biological to the other meshes. © Georg Thieme Verlag KG Stuttgart · New York.

ABO-incompatible liver transplantation (ILT) was formerly contraindicated because of the increased risk of antibody-mediated humoral graft rejection due to preformed anti-A/-B antibodies on recipient endothelial cells. A 2.5-year-old girl with end-stage liver disease underwent cadaveric donation ILT because of acute liver failure and esophageal variceal bleeding before transplantation. The patient's blood type was A Rh (-) and the donor's blood type B Rh (+). The operation and postoperative course were uneventful. The immunosuppression consisted of steroids, and tacrolimus was initiated on the day of the surgery. The patient's hemoglobin level did not change, and direct Coombs test performed daily was consistently negative. Anti-B titer was observed at a maximum of 1/8. The patient was followed up during the first year. This case of ILT from a cadaveric donor is significant because the 2.5-year-old recipient did not experience any complications after undergoing routine immunosuppressive treatment.

Combined heart and liver transplantation for familial amyloid polyneuropathy (FAP) is currently the best treatment for patients with cardiomyopathy related to FAP. However, its optimal timing and the possibility of domino liver transplantation in this setting remain under discussion. Most such cases in the medical literature have been performed simultaneously, although many of them have required the use of veno-venous bypass and the majority have not used the liver as a graft for domino liver transplantation. We report 3 cases of non-Val30Met mutation that underwent sequential heart and domino liver transplantation at our institution. We describe the 3 cases and the medical literature, with special attention to the reason for sequential heart and liver transplantation, the role of transient elastography in this setting, and the feasibility of domino liver transplantation. In our experience, combined heart and liver transplantation is a feasible but challenging procedure for patients with FAP. Performing the procedure sequentially rather than simultaneously seems safer and easier, both technically and hemodynamically. More importantly, such an approach allows the use of livers from FAP patients as grafts for domino liver transplantation. Copyright © 2013 Elsevier España, S.L. All rights reserved.

Various types of extracorporeal membrane oxygenation methods have been used in liver transplant operations. The main indications are portopulmonary or hepatopulmonary syndromes and other cardiorespiratory failure syndromes that are refractory to conventional therapy. There is little literature available about extracorporeal membrane oxygenation, especially after liver transplant. We describe our experience with 2 patients who had living-related liver transplant. A 69-year-old woman had refractory aspergillosis pneumonia and underwent pumpless extracorporeal lung assist therapy 4 weeks after liver transplant. An 8-month-old boy with biliary atresia underwent urgent liver transplant; he received venoarterial extracorporeal membrane oxygenation therapy on postoperative day 1. Despite our unsuccessful experience with 2 patients, extracorporeal membrane oxygenation and pumpless extracorporeal lung assist therapy for liver transplant patients may improve prognosis in selected cases.

Maple syrup urine disease (MSUD) is a rare hereditary metabolic condition where the body is unable to breakdown amino acids causing toxic buildup. Acute and long-term management of MSUD involves a restricted diet and regular monitoring of amino acid levels; however, more recently liver transplants have been shown to be successful in treating this condition. Even with successful management of MSUD there is evidence from pediatric cases that shows a distinct pattern of neurocognitive deficits associated with this condition, including impaired nonverbal skills and psychomotor functioning with relatively intact verbal abilities. In the present paper, we report an adult case of MSUD with associated neurocognitive deficits and functional limitations following liver transplantation. Neuroimaging revealed no structural abnormalities, while the results from the neuropsychological evaluation showed impairment in visual-spatial processing, attention, executive functioning, and psychomotor abilities, with relative strengths in verbal skills. The patient also showed reduced adaptive functioning and mild anxiety. This case demonstrates neurocognitive deficiencies within the context of normal magnetic resonance imaging. The possible underlying mechanism of this neuropsychological profile is discussed in relation to other neurodevelopmental models.

Liver transplantation remains an effective treatment for those with end-stage disease and with intractable liver-related symptoms. The shortage of organs for transplantation has resulted in the need for rationing. A variety of approaches to selection and allocation have been developed and vary from country to country. The shortage of donors has meant that new approaches have to be adopted to make maximal use of the available organs; these include splitting grafts, use of extended criteria livers, livers from non-heart-beating donors and from living donors. Post transplantation, most patients will need life-long immunosuppression, although a small proportion can have immunosuppression successfully withdrawn. Newer immunosuppressive drugs and different strategies may allow a more targeted approach with a reduction in side-effects and so improve the patient and graft survival. For autoimmune diseases, transplantation is associated with significant improvement in the quality and length of life. Disease may recur after transplantation and may affect patient and graft survival. PMID:18528936

Hepatitis-C-virus- (HCV-) related end-stage cirrhosis is the primary indication for liver transplantation in many countries. Unfortunately, however, HCV is not eliminated by transplantation and graft reinfection is universal, resulting in fibrosis, cirrhosis, and finally graft decompensation. The use of poor quality organs, particularly from older donors, has a highly negative impact on the severity of recurrence and patient/graft survival. Although immunosuppressive regimens have a considerable impact on the outcome, the optimal regimen after liver transplantation for HCV-infected patients remains unclear. Disease progression monitoring with protocol biopsy and new noninvasive methods is essential for predicting patient/graft outcome and starting antiviral treatment with the appropriate timing. Antiviral treatment with pegylated interferon and ribavirin is currently considered the most promising regimen with a sustained viral response rate of around 30% to 35%, although the survival benefit of this regimen remains to be investigated. Living-donor liver transplantation is now widely accepted as an established treatment for HCV cirrhosis and the results are equivalent to those of deceased donor liver transplantation. PMID:22900194

Castleman disease is a rare hematologic disorder, closely linked to the HHV-8, and most commonly observed in immunocompromised individuals. Thirteen months following a liver transplant for CPS-1 defect, a 15-month-old boy presented with fevers, anemia, and growth retardation. Abdominal CT scan showed splenomegaly and generalized lymphadenopathy. Histology of chest wall lymph nodes revealed a mixed CD3+ T-cell and CD20+ B-cell population with atretic germinal centers consistent with multicentric Castleman disease. Qualitative DNA PCR detected HHV-8 in the resected lymph node and in the blood, supporting the diagnosis. Immunosuppression was tapered, and he was transitioned from tacrolimus to sirolimus. His graft function remained stable, and repeat imaging showed regression of the lymphadenopathy. The child is living one yr after Castleman disease diagnosis with a well-functioning graft. Castleman disease is a potential complication of solid organ transplant and HHV-8 infection. Reduction in immunosuppression and switch to sirolimus may be an effective strategy to treat this condition. © 2011 John Wiley & Sons A/S.

Liver transplantation is a standard life-saving procedure for the treatment of many end-stage liver diseases. The success of this procedure may be limited by infectious complications. In this article, we review the contemporary state of infectious complications during the post-operative period, with particular emphasis on those that occur most commonly during the first 6 mo after liver transplantation. Bacteria, and less commonly Candida infections, remain the predominant pathogens during the immediate post-operative period, especially during the first month, and infections caused by drug-resistant strains are emerging. Infections caused by cytomegalovirus and Aspergillus sp. present clinically during the “opportunistic” period characterized by intense immunosuppression. As newer potent immunosuppressive therapies with the major aim of reducing allograft rejection are developed, one potential adverse effect is an increase in certain infections. Hence, it is essential for liver transplant centers to have an effective approach to prevention that is based on predicted infection risk, local antimicrobial resistance patterns, and surveillance. A better understanding of the common and most important infectious complications is anticipated to lead to improvements in quality of life and survival of liver transplant recipients. PMID:21603030

Infectious complications are major causes of morbidity and mortality after liver transplantation, despite recent advances in the transplant field. Bacteria, fungi, viruses and parasites can cause infection before and after transplantation. Among them, bacterial infections are predominant during the first two months post-transplantation and affect patient and graft survival. They might cause surgical site infections, including deep intra-abdominal infections, bacteremia, pneumonia, catheter-related infections and urinary tract infections. The risk factors for bacterial infections differ between the periods after transplant, and between centers. Recently, the emergence of multi-drug resistant bacteria is great concern in liver transplant (LT) patients. The instructive data about effects of infections with extended-spectrum beta lactamase producing bacteria, carbapenem-resistant gram-negative bacteria, and glycopeptide-resistant gram-positive bacteria were reported on a center-by-center basis. To prevent post-transplant bacterial infections, proper strategies need to be established based upon center-specific data and evidence from well-controlled studies. This article reviewed the recent epidemiological data, risk factors for each type of infections and important clinical issues in bacterial infection after LT.

Nephrotoxicity is one of the most common side effects of long-term immunosuppressive therapy with calcineurin inhibitors. We describe a case of distal renal tubular acidosis secondary to tacrolimus administration. A 43-year-old man with end-stage liver disease due to hepatitis C and B virus infections and alcoholic cirrhosis received a liver transplantation under immunosuppressive treatment with tacrolimus and mycophenolate mofetil. In the postoperative period, the patient developed hyperkalemic hyperchloremic metabolic acidosis, with a normal serum anion gap and a positive urinary anion gap, suggesting distal renal tubular acidosis. We excluded other causes of hyperkalemia. Administration of intravenous bicarbonate, loop diuretics, and oral resin exchanger corrected the acidosis and potassium levels. Distal renal tubular acidosis is one of several types of nephrotoxicity induced by tacrolimus treatment, resulting from inhibition of potassium secretion in the collecting duct. Treatment to correct the acidosis and hyperkalemia should be promptly initiated, and the tacrolimus dose adjusted when possible.
The constant updating in the field of liver transplant led to the holding of the III Consensus Meeting of the Spanish Liver Transplant Association. Three current topics of great clinical interest were debated during this meeting; transplant in patients with liver cirrhosis due to hepatitis C, live donor liver transplant and the evaluation of the quality of liver grafts. A subject of great interest to Liver Transplant Units was also discussed: the assessment of their quality.

Since liver transplantation was first performed in 1968 by Starzl et al, advances in case selection, liver surgery, anaesthetics, and immunotherapy have significantly increased the indications for and success of this operation. Liver transplantation is now a standard therapy for many end stage liver disorders as well as acute liver failure. However, while demand for cadaveric organ grafts has increased, in recent years the supply of organs has fallen. This review addresses current controversies resulting from this mismatch. In particular, methods for increasing graft availability and difficulties arising from transplantation in the context of alcohol related cirrhosis, primary liver tumours, and hepatitis C are reviewed. Together these three indications accounted for 42% of liver transplants performed for chronic liver disease in the UK in 2000. Ethical frameworks for making decisions on patients' suitability for liver transplantation have been developed in both the USA and the UK and these are also reviewed. PMID:11884694

Two cases of hereditary tyrosinemia presented with ascites and coagulopathy in infancy. Both patients underwent liver transplantation at the age of 25 and 36 mo, respectively. Both cases had normal liver function 37 and 24 mo later. The native liver in each case showed mixed micro- and macronodular cirrhosis with hepatocellular dysplasia, including both the large and small cell varieties. One of the subjects had also shown dysplasia in a prior liver biopsy. We compared the hepatic morphology with that from two other cases from our autopsy files. One of these (a female, 9 mo old) showed dysplasia, and the other (her male sibling, 4 yr old) had a liver cell carcinoma with lung metastases. These observations confirm prior reports that neoplastic transformation occurs early in the natural history of hereditary tyrosinemia despite meticulous dietary management and other supportive treatment. With the detection of liver cell dysplasia, efforts should be intensified to find an appropriate donor. Liver transplantation cures the hepatic disease and should be performed before malignancy develops.

ABO-incompatibility is a major obstacle to expanding exiguous donor pools in adult liver transplantation, especially in countries where grafts from deceased donors are uncommon. We present our preliminary results of ABO-incompatible (ABO-I) adult living donor liver transplantation (LDLT) using a new, simple protocol. Seven consecutive cases of ABO-I LDLT were managed by the same protocol including pre-operative administration of a single dose of rituximab (375 mg/m(2) ) followed by three to five sessions of plasma exchange before LDLT without portal infusion therapy. The triple immunosuppression protocol consisted of tacrolimus, mycophenolate mofetil and steroids, with mycophenolate mofetil starting seven d before LDLT. Splenectomy was performed for all cases. All patients are alive (100% survival) with a mean follow-up of 852 d (715-990 d). Neither antibody-mediated nor hyperacute rejection were encountered. There was only one episode of mild acute cellular rejection, for which steroid augmentation was effective. The median preformed isoagglutinin antibody titer before plasma exchange was 256, while the median antibody titer immediately before LDLT was 16. In conclusion, adult ABO-I LDLT results were excellent - comparable or even superior to those of ABO-compatible LDLT. ABO-I adult LDLT has now become a more applicable modality without the need for an appropriate donor.

Propylthiouracil- (PTU-) induced hepatotoxicity is rare but potentially lethal with a spectrum of liver injury ranging from asymptomatic elevation of transaminases to fulminant hepatic failure and death. We describe two cases of acute hepatic failure due to PTU that required liver transplantation. Differences in the clinical presentation, histological characteristics, and posttransplant management are described as well as alternative therapeutic options. Frequent monitoring for PTU-induced hepatic dysfunction is strongly advised because timely discontinuation of this drug and implementation of noninvasive therapeutic interventions may prevent progression to liver failure or even death.

The aim of this paper was to report the case of type 2 diabetes and significant insulin resistance that improved dramatically after removal of a pheochromocytoma in a liver transplant recipient , and to provide a review of the relevant literature. We describe the clinical presentation, diagnostic results and management of the patient. In addition, we performed a PubMed search for related English language articles, to provide an overview of the pertinent literature. A 53 year old woman with a history of an orthotopic liver transplantation and insulin-requiring type 2 diabetes was admitted to the hospital with fever, diaphoresis, tachycardia and hypertension. A pheochromocytoma was diagnosed and removed. The patient subsequently developed hypoglycemia and required no further insulin therapy. Pheochromocytomas have been described to lead to hyperglycemia and diabetes, due to the suppression of insulin release and increased insulin resistance. Furthermore, a review of the literature revealed only 3 other reported cases of pheochromocytomas in organ transplant recipients. None of these pheochromocytomas were believed to have occurred de novo after transplantation. This is the first report of a pheochromocytoma in a liver transplant recipient and possibly the first case of a de novo pheochromocytoma in any organ transplant recipient. Moreover, this case showcases pheochromocytomas as a rare cause of diabetes mellitus.

In 1958 Francis Moore described the orthotopic liver transplantation technique in dogs. In 1963, Starzl et al. performed the first liver transplantation. In the first five liver transplantations no patient survived more than 23 days. In 1967, stimulated by Calne who used antilymphocytic serum, Starzl began a successful series of liver transplantation. Until 1977, 200 liver transplantations were performed in the world. In that period, technical problems were overcome. Roy Calne, in 1979, used the first time cyclosporine in two patients who had undergone liver transplantation. In 1989, Starzl et al. reported a series of 1,179 consecutives patients who underwent liver transplantation and reported a survival rate between one and five years of 73% and 64%, respectively. Finally, in 1990, Starzl et al. reported successful use of tacrolimus in patents undergoing liver transplantation and who had rejection despite receiving conventional immunosuppressive treatment. Liver Transplantation Program was initiated at Hospital Israelita Albert Einstein in 1990 and so far over 1,400 transplants have been done. In 2013, 102 deceased donors liver transplantations were performed. The main indications for transplantation were hepatocellular carcinoma (38%), hepatitis C virus (33.3%) and alcohol liver cirrhosis (19.6%). Of these, 36% of patients who underwent transplantation showed biological MELD score > 30. Patient and graft survival in the first year was, 82.4% and 74.8%, respectively. A major challenge in liver transplantation field is the insufficient number of donors compared with the growing demand of transplant candidates. Thus, we emphasize that appropriated donor/receptor selection, allocation and organ preservation topics should contribute to improve the number and outcomes in liver transplantation. PMID:25993082

In Egypt there is no doubt that chronic liver diseases are a major health concern. Hepatitis C virus (HCV) prevalence among the 15−59 years age group is estimated to be 14.7%. The high prevalence of chronic liver diseases has led to increasing numbers of Egyptian patients suffering from end stage liver disease (ESLD), necessitating liver transplantation (LT). We reviewed the evolution of LT in Egypt and the current status. A single center was chosen as an example to review the survival and mortality rates. To date, deceased donor liver transplantation (DDLT) has not been implemented in any program though Egyptian Parliament approved the law in 2010. Living donor liver transplantation (LDLT) seemed to be the only logical choice to save many patients who are in desperate need for LT. By that time, there was increase in number of centers doing LDLT (13 centers) and increase in number of LDLT cases [2,400] with improvement of the results. Donor mortality rate is 1.66 per 1,000 donors; this comprised four donors in the Egyptian series. The exact recipient survival is not accurately known however, and the one-year, three-year and five-year survival were 73.17%, 70.83% and 64.16% respectively in the International Medical Center (IMC) in a series of 145 adult to adult living donor liver transplantation (AALDLT) cases. There was no donor mortality in this series. LDLT are now routinely and successfully performed in Egypt with reasonable donor and recipient outcomes. Organ shortage remains the biggest hurdle facing the increasing need for LT. Although LDLT had reasonable outcomes, it carries considerable risks to healthy donors. For example, it lacks cadaveric back up, and is not feasible for all patients. The initial success in LDLT should drive efforts to increase the people awareness about deceased organ donation in Egypt. PMID:27115003

To describe our experience of pediatric living donor liver transplantation from India over a period of 12 year. A retrospective analysis of 200 living donor liver transplantation in children (18 years or younger) was done for demographic features, indications, donor and graft profile and outcome. Between September 2004 and July 2016, 200 liver transplants were performed on 197 children. Fifty transplants were done in initial 6 years and 150 in next 6 years. All donors (51% mothers) were discharged with a mean stay of 7 days. The leading indications of liver transplants were cholestatic liver disease (46%) followed by metabolic liver disease (33%) and acute liver failure /acute on chronic liver failure (28.5%). Biliary leakage (8.5%), biliary stricture (9%), hepatic artery thrombosis (4.5%) and portal vein thrombosis (4%) were the most common surgical complications; all could be managed by surgical or interventional radiological measures, except in one child who died. Sepsis, acute rejection and CMV hepatitis in first 6 months were seen in 14.5%, 25% and 17% cases, respectively. Post-transplant lymphoproliferative disease was seen in only 1.5%. Re-transplant rate was 1.5%. The overall 1 year survival rate was 94% and 5 year actuarial survival was 87% with no statistically significant difference between children weight < 10 kg vs. > 10 kg. Outcome in acute liver failure did not differ significantly between those with acute on chronic liver failure vs. those with chronic liver disease. Advances in medical and surgical techniques associated with multidisciplinary teams including skilled pediatric liver transplant surgeons, anesthetists, dedicated pediatric hepatologists, pediatric intensivists, interventional radiologists and pathologists resulted in an excellent outcome of living related liver transplants in children. Low age and weight of the baby does not seem to be a contraindication for liver transplantation as outcome were comparable in our experience.

Obesity has become increasingly prevalent, and the number of obese patients in need of liver transplant is expected to continue to increase. In addition, liver disease due to nonalcoholic fatty liver disease is expected to become the leading cause of liver transplantation in the near future. However, obesity remains a relative contraindication in liver transplant. New strategies in managing this patient population are clearly needed. To this end, the authors review the current literature on the efficacy of bariatric surgery in the setting of liver transplantation in obese patients. Copyright © 2016 Elsevier Inc.

Primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC) and autoimmune hepatitis (AIH) represent the three major autoimmune liver diseases (AILD). PBC, PSC, and AIH are all complex disorders in that they result from the effects of multiple genes in combination with as yet unidentified environmental factors. Recent genome-wide association studies have identified numerous risk loci for PBC and PSC that host genes involved in innate or acquired immune responses. These loci may provide a clue as to the immune-based pathogenesis of AILD. Moreover, many significant risk loci for PBC and PSC are also risk loci for other autoimmune disorders, such type I diabetes, multiple sclerosis and rheumatoid arthritis, suggesting a shared genetic basis and possibly similar molecular pathways for diverse autoimmune conditions. There is no curative treatment for all three disorders, and a significant number of patients eventually progress to end-stage liver disease requiring liver transplantation (LT). LT in this context has a favourable overall outcome with current patient and graft survival exceeding 80% at 5years. Indications are as for other chronic liver disease although recent data suggest that while lethargy improves after transplantation, the effect is modest and variable so lethargy alone is not an indication. In contrast, pruritus rapidly responds. Cholangiocarcinoma, except under rigorous selection criteria, excludes LT because of the high risk of recurrence. All three conditions may recur after transplantation and are associated with a greater risk of both acute cellular and chronic ductopenic rejection. It is possible that a crosstalk between alloimmune and autoimmune response perpetuate each other. An immunological response toward self- or allo-antigens is well recognised after LT in patients transplanted for non-autoimmune indications and sometimes termed "de novo autoimmune hepatitis". Whether this is part of the spectrum of rejection or an autoimmune

AIM To describe one case of bilateral Tapia’s syndrome in a liver transplanted patient and to review the literature. METHODS We report a case of bilateral Tapia’s syndrome in a 50-year-old man with a history of human immunodeficiency virus and hepatitis C virus child. A liver cirrhosis and a bi-nodular hepatocellular carcinoma, who underwent liver transplantation after general anesthesia under orotracheal intubation. Uneventful extubation was performed in the intensive care unit during the following hours. On postoperative day (POD) 3, he required urgent re-laparotomy due to perihepatic hematoma complicated with respiratory gram negative bacilli infection. On POD 13, patient was extubated, but required immediate re-intubation due to severe respiratory failure. At the following day a third weaning failure occurred, requiring the performance of a percutaneous tracheostomy. Five days later, the patient was taken off mechanical ventilation and severe dysphagia, sialorrea and aphonia revealed. A computerized tomography and a magnetic resonance imaging of the head and neck excluded central nervous injury. A stroboscopy showed bilateral paralysis of vocal cords and tongue and a diagnosis of bilateral Tapia’s syndrome was performed. With conservative management, including a prompt establishment of a speech and swallowing rehabilitation program, the patient achieved full recovery within four months after liver transplantation. We carried out MEDLINE search for the term Tapia’s syndrome. The inclusion criteria had no restriction by language or year but must provide sufficient available data to exclude duplicity. We described the clinical evolution of the patients, focusing on author, year of publication, age, sex, preceding problem, history of endotracheal intubation, unilateral or bilateral presentation, diagnostic procedures, type of treatment, follow-up, and outcome. RESULTS Several authors mentioned the existence of around 70 cases, however only 54 fulfilled our
THE ONLY TREATMENT: Liver transplantation (LT) is currently the final treatment for most types of end-stage liver diseases including alcoholic cirrhosis, so far alcoholic cirrhosis has become the first indication for LT in France and other western countries, accounting for 25% of all procedures. However due to ethical issues and also the discrepancy between the theoretical number of candidates and available organs, indications for LT in alcoholic cirrhosis must be rigorously defined. On the average, candidates are 50 years old, males in two-thirds of the cases, with pre-terminal liver disease combining advanced-stage liver dysfunction (PT < 40%, bilirubin > 50 mumol/l, albumin < 30 g/l) and intractable ascitis. The gain in survival being best in patients with severe cirrhosis (Child-Pugh grade C), these patients should be given priority when liver function fails to improve despite prolonged abstention. For less advanced diseases (Child-Pugh B or A), LT can be considered after failure of symptomatic medical treatments or in case a small hepatocellular carcinoma develops. The list includes presence of extrahepatic organ failure, generally related to alcohol-tobacco abuse (cardiomyopathy, pancreatitis, neuropathy, squamous cell carcinoma ...) and precarious psychosocial situations exposing the patient to the risk of recurrent alcoholism and non-compliance after transplantation. Predictive factors of after recidivism after transplantation are preoperative abstinence of less than 6 months duration, denial of alcoholism, lack of familial and occupational support, antisocial behavior and a history of psychiatric disorders or drug abuse. Patients with several of these risk factors cannot reasonably be considered as candidates for LT. Inversely, transplantation should be proposed for patients with no or few risk factors due to the excellent physical and social outcome observed. Generally, a full 6 months of preoperative abstinence is required by most transplantation centers

Summary Hepatic artery thrombosis (HAT) is a dreadful complication of orthotopic liver transplantation (OLT). This complication occurred in 27 grafts (68% = 27/393 grafts) in 25 patients (9% = 25/313 patients). HAT was responsible for a high mortality (64% = 16/25 patients) despite a high retransplantation rate (70% = 19/27 grafts). HAT should be suspected in case of fulminant liver failure, delayed bile leak or unexplained fever of sepsis of unknown etiology occurring after liver transplantation. Pulsed doppler examination and arteriogram are the decisive diagnostic procedures. Patients presenting HAT can only be rescued by early diagnosis and retransplantation. Aneurysms of the hepatic arterial supply must also be treated urgently, either by conventional vascular repair if possible or by retransplantation, because or the high incidence of fatal rupture (3/4 patients = 75%).

Alcoholic liver disease is an established, yet controversial, indication for liver transplantation. Although an abstinence period of up to 6 mo prior to transplantation is mandatory, alcohol relapse after transplantation is a common event. In case of recurrence of heavy drinking, graft survival is significantly impaired. Guidelines on detection and surveillance of alcohol consumption in this patient cohort are lacking. This review summarizes the challenge of patient selection as well as the current knowledge on established and novel alcohol biomarkers with special focus on liver transplant candidates and recipients.

Liver transplantation with preservation of the recipient vena cava (piggyback technique) has been performed as an alternative to the conventional method. Outflow disturbance or obstruction of the vena cava in the early period after liver transplantation is associated with high morbidity and mortality. We used side-to-side cavo-caval anastomosis (modified piggyback technique) in a deceased-donor liver transplantation (DDLT) for venous outflow reconstruction. On postoperative day 9, the patient developed abdominal discomfort, and abnormal liver function showing serum total bilirubin of 6.2 mg/dl and serum AST/ALT of 297/597 IU/L. Doppler ultrasound showed mono-phasic wave forms of the hepatic vein. Computed tomography showed focal narrowing of 9.5 mm×12 mm in diameter at the cavo-caval anastomosis site. Liver biopsy was showed that there was no evidence of acute allograft rejection. Direct venogram showed stenosis of the cavo-caval anastomosis with a pressure gradient of 12 mmHg. An interventional stent was inserted in the stenotic site of the inferior vena cava, and the pressure gradient decreased to 2 mmHg. He was discharged from hospital on postoperative day 23 without any other complications. Herein we report a case of deceased-donor liver transplantation using the modified piggyback technique, who received an inferior vena cava stent due to stricture of the reconstructed orifice of the vena cava.

The urea cycle is the final pathway for nitrogen metabolism. Urea cycle disorders (UCDs) include a variety of genetic defects, which lead to inefficient urea synthesis. Elevated blood ammonium level is usually dominant in the clinical pattern and the primary manifestations affect the central nervous system. Herein, we report the case of a 17-year-old girl who was diagnosed with UCD at the age of 3. Despite a controlled diet, she was hospitalized several times for acute attacks with recurrent life risk. She came to our attention for a hyperammonemic episode. We proposed an orthotopic liver transplant (OLT) as a treatment; the patient and her family were in complete agreement. On February 28, 2007, she successfully received a transplant. Following the surgery, she has remained well, and she is currently leading a normal life. Usually for UCDs diet plays the primary therapeutic role, while OLT is often considered as a last resort. Our case report and the recent literature data on the quality of life and prognosis of traditionally treated patients vs OLT patients, support OLT as a primary intervention to prevent life-threatening acute episodes and chronic mental impairment.

Hepatoblastoma is the most common pediatric liver tumor and is usually diagnosed before five years of age. Treatment consists of a combination of chemotherapy and surgery, with the goal being attainment of complete local control by surgical resection and eradication of any extrahepatic disease. Neoadjuvant chemotherapy is utilized and is often beneficial in rendering tumors resectable; however, prolonged chemotherapy administration attempting to render tumors resectable by conventional resection should be avoided. For patients whose tumors are too extensive to be conventionally resected, liver transplantation can be curative and remains the treatment of choice for eligible patients otherwise incurable by conventional resection.

Split liver transplantation (SLT), while widely accepted in pediatrics, remains underutilized in adults. Advancements in surgical techniques and donor-recipient matching, however, have allowed expansion of SLT from utilization of the right trisegment graft to now include use of the hemiliver graft as well. Despite less favorable outcomes in the early experience, better outcomes have been reported by experienced centers and have further validated the feasibility of SLT. Importantly, more than two decades of experience have identified key requirements for successful SLT in adults. When these requirements are met, SLT can achieve outcomes equivalent to those achieved with other types of liver transplantation for adults. However, substantial challenges, such as surgical techniques, logistics, and ethics, persist as ongoing barriers to further expansion of this highly complex procedure. This review outlines the current state of SLT in adults, focusing on donor and recipient selection based on physiology, surgical techniques, surgical outcomes, and ethical issues. PMID:27672272
We present a case of an alveolar-pleural fistula with hepatic hydrothorax in a patient undergoing orthotropic liver transplantation, which was detected by drainage of transudate through an endotracheal tube during operation. A standard endotracheal tube was changed to a double-lumen tube to provide differential lung ventilation. The patient was diagnosed with an alveolar-pleural fistula by direct vision of an air leak during positive-pressure ventilation through a diaphragmatic incision. There was still a concern about worsening his ventilation due to persistent aspiration of pleural effusion towards the ipsilateral lung during the remaining operation period. Surgeon repaired the defect on the exposed lung surface via diaphragmatic opening. Anesthesiologists should consider an alveolar-pleural fistula as a possible differential diagnosis with re-expansion pulmonary edema when transudate emanating from the endotracheal tube is obtained in patients with massive hydrothorax.

Orthotopic liver transplantation (OLT) is the standard of care for patients with decompensated cirrhosis and for patients with hepatocellular carcinoma. More than 6000 liver transplants are performed annually in the United States. High patient and graft survival rates have been achieved in great part due to the availability of potent immunosuppressive agents. Systemic immunosuppression has rendered the liver recipient susceptible to de novo infections as well as reactivation of preexisting latent infections. Infections occurring during the first month post-OLT are usually nosocomial, donor-derived, or the result of a perioperative complication. The development of opportunistic infections (OIs) such as Aspergillus and the reactivation of latent infections such as Mycobacterium tuberculosis are more frequent 1 to 6 months posttransplant, when the net state of immunosuppression is the highest. Immunosuppressive therapy is tapered 6 to 12 months post-OLT; therefore, infections occurring during that time period and afterward generally resemble those of the general population. Screening strategies applied to determine the risk of an infection after transplantation and the use of prophylactic antimicrobial therapy have reduced the incidence of OIs after OLT. This article will review the various causes of infection post-OLT and the therapies used to manage complications. PMID:27134589

The objective of this pilot study was to investigate the potential for long-term overall survival (OS) after liver transplantation for colorectal liver metastases (CLMs). Patients with nonresectable CLMs have poor prognosis, and few survive beyond 5 years. CLMs are currently considered an absolute contraindication for liver transplantation, although liver transplantation for primary and some secondary liver malignancies shows excellent outcome in selected patients. Before 1995, several liver transplantations for CLMs were performed, but outcome was poor (5-year survival rate: 18%) and liver transplantation for CLMs was abandoned. Since then, the survival rate after liver transplantation in general has improved by almost 30%. On the basis of this, a 5-year survival rate of about 50% after liver transplantation for CLMs could be anticipated. In a prospective pilot study, liver transplantation for nonresectable CLMs was performed (n = 21). Main inclusion criteria were liver-only CLMs, excised primary tumors, and at least 6 weeks of chemotherapy. Kaplan-Meier estimates of the OS rate at 1, 3, and 5 years were 95%, 68%, and 60%, respectively. Metastatic recurrence of disease was common (mainly pulmonary). However, a significant proportion of the recurrences were accessible for surgery, and at follow-up (after median of 27 months; range, 8-60), 33% had no evidence of disease. Hepatic tumor load before liver transplantation, time from primary surgery to liver transplantation, and progressive disease on chemotherapy were identified as significant prognostic factors. OS exceeds by far reported outcome for chemotherapy, which is the only treatment option available for this patient group. Furthermore, OS is comparable with liver resection for resectable CLMs and survival after repeat liver transplantation for nonmalignant diseases. Selection strategies based on prognostic factors may further improve the outcome (ClinicalTrials.gov: NCT01311453).

Aplastic anemia (AA) has been observed in nearly a third of patients undergoing liver transplantation (LT) for non-A-E fulminant hepatic failure (FHF). Few of these patients have been successfully managed with sequential LT and bone marrow transplantation (BMT). No causative agent has been identified for the FHF or AA in these reported cases. At our center, two patients, aged 15 years and 7 years, respectively, underwent sequential living-related LT and living-unrelated BMT. These patients are 10/9 years and 5/4 years post-LT/BMT. Human parvovirus B19 (HPV-B19) was established as the causative agent for FHF in both these patients by polymerase chain reaction. This report presents the first two cases associating HPV-B19 with FHF and AA who underwent sequential LT and BMT with excellent outcomes. © Copyright 2014 The American Society of Transplantation and the American Society of Transplant Surgeons.

The acute renal failure is the frequent medical complication observed in liver transplant patients. The objective of this study was to determine the cause of acute renal failure in post liver transplant patients. A total of 70 patients who underwent (cadaveric 52, live 18) liver transplantation were categorized based on clinical presentation into two groups, namely hepatorenal failure (HRF, n = 29), and Hepatic failure (HF, n = 41). All the patients after the liver transplant had received tacrolimus, mycophenolate and steroids. We analyzed the modification of diet in renal disease, (MDRD) serum urea, creatinine and albumin before and after 5th and 30th day of liver transplant and data was categorized into survivors and non-survivors group. In HRF survivor group, serum creatinine, and urea levels were high and, albumin, MDRD were low in pre- transplant and reached to normal levels on 30th day of post transplant, and 79.3 % of patients in this group showed resumption of normal kidney function. On the contrary in HRF nonsurvivor group, we did not observed any significant difference and 20.7 % of patients showed irreversible changes after the liver transplant. In HF survivor group, 82.9 % of liver failure patients did not show any deviation in serum creatinine, urea, albumin and MDRD, whereas in HF non survivor group, 17.1 % of liver failure patients who had HCV positive before the transplant developed acute renal failure. The levels of creatinine, urea, albumin and MDRD were normal before the transplant and on day 30th, the levels of albumin and MDRD were significantly low whereas serum urea, creatinine levels were high. In conclusion, based on these observations, an diagnosis and treatment of Acute renal failure is important among the liver transplantation cases in the early postoperative period.

This study aims to investigate the causes and treatment experience of severe abdominal infection after orthotopic liver transplantation. Clinical data were retrospectively analysed in perioperative severe abdominal infection of 186 orthotopic liver transplantation cases from March 2004 to November 2011. Among the 186 patients, 16 cases had severe abdominal infection: five cases had bile duct anastomotic leakage-inducing massive hydrops and infection under liver interstice, 10 cases had extensive bleeding of surgical wound leading to massive haematocele and infection around the liver, and one case had postoperative lower oesophageal fistula leakage causing massive hydrops and infection under the left diaphragm. After definite diagnosis, 12 cases underwent surgery within three days, with no death. Among the four cases that underwent surgery three days after diagnosis, one case died of multiple-organ failure five days after abdominal cavity exploration, which was performed 21 days after liver transplantation. Severe abdominal infections after liver transplantation were the most common causes of death in perioperative liver transplantation. Comprehensive treatment with efficacious antibiotics, multiple-organ support, controlled surgical removal of the lesion, and adequate drainage establishment was the key to the entire treatment.

Familial amyloid polyneuropathy (FAP) is the most serious of the hereditary neuropathies in adults and is due to endoneurial amyloid deposits. These sensorimotor and autonomic diseases are very progressive and disabling. A "typical" patient with FAP is 30-years-old, of Portuguese origin, and has insidiously developed pains or sensory loss in the feet and digestive disorders, such as diarrhea, and has lost weight. Clinical examination shows sensory polyneuropathy of the distal small fibers (with sensory loss prevailing over sensations of temperature and pain). Cardiac disorders are frequent. One parent will have died prematurely from this disease. FAP are fatal 10.8 years after the first symptoms, on average. Neuropathy is usually associated with cardiac manifestations, weight loss, and more rarely renal or eye complications. FAP are secondary to a point mutation of the transthyretin (TTR) or prealbumin gene (18q11.2-q12.1), of which there are 40 variants. In France, the variant TTRMet30 is present in half of all cases and one third of FAP patients present with sporadic disease. Liver transplantation has been proposed as a treatment for FAP because the liver is the main source of variant amyloidogenic TTR. Transplantation makes it possible to eliminate 98% of the variant TTR in the serum, doubles median survival for variant TTRMet30 carriers, and halts the progress of the sensorimotor neuropathy over the long term in 62% of cases. No regression or recurrence has been observed. Poor prognostic factors after liver transplantation are a mutation other than the TTRMet30 variant, severe neuropathy, and late onset. Liver transplantation must be proposed to the symptomatic patients as early as possible. It should be performed in a center specialized in FAP. After LT, periodic follow-up in such a center is essential. Copyright 2009 Elsevier Masson SAS. All rights reserved.

AIM To evaluate risk of recidivism on a case-by-case basis. METHODS From our center’s liver transplant program, we selected patients with alcoholic liver disease who were listed for transplant based on Ohio Solid Organ Transplantation Consortium (OSOTC) exception criteria. They were considered to have either a low or medium risk of recidivism, and had at least one or three or more months of abstinence, respectively. They were matched based on gender, age, and Model for End-Stage Liver Disease (MELD) score to controls with alcohol-induced cirrhosis from Organ Procurement and Transplant Network data. RESULTS Thirty six patients with alcoholic liver disease were approved for listing based on OSOTC exception criteria and were matched to 72 controls. Nineteen patients (53%) with a median [Inter-quartile range (IQR)] MELD score of 24 (13) received transplant and were followed for a median of 3.4 years. They were matched to 38 controls with a median (IQR) MELD score of 25 (9). At one and five years, cumulative survival rates (± standard error) were 90% ± 7% and 92% ± 5% and 73% ± 12% and 77% ± 8% in patients and controls, respectively (Log-rank test, P = 0.837). Four (21%) patients resumed drinking by last follow-up visit. CONCLUSION Compared to traditional criteria for assessment of risk of recidivism, a careful selection process with more flexibility to evaluate eligibility on a case-by-case basis can lead to similar survival rates after transplantation.

Some chromosomal alterations can be associated with vascular abnormalities. For instance, Turner syndrome can be complicated by agenesis or hypoplasia of the portal venous system causing presinusoidal portal hypertension. Liver transplantation to treat this condition overcomes portal hypertension and reconstitutes the diminished hepatic function due to severe atrophy of the portal venous inflow.

Anemia is a common finding in post-liver transplant patients. Causes for the anemia include nutritional deficiencies, red cell aplasia as well as immune-mediated hemolysis. One of the immunologic causes of hemolytic anemia is drug-induced hemolysis. Tacrolimus is a common immunosuppressant used in post-liver transplant patients to prevent graft rejection. There have been reports of tacrolimus-associated hemolytic anemia secondary to hemolytic uremic syndrome as well as autoimmune hemolysis. There are also case-reports of severe hemolytic anemia related to cold agglutinin production in post-liver transplant patients. We described in this paper three cases of severe cold agglutinin hemolytic anemia in three pediatric liver transplant patients. Steroid therapy, plasmapheresis and withdrawal of tacrolimus led to resolution of the severe hemolytic process in each case. Whether the immune-mediated hemolysis is related to tacrolimus is not clear and needs to be characterized further.

Two patients with situs inversus and biliary atresia were treated with hepatic transplantation, one with an auxiliary liver and the other with an orthotopic graft which was placed using a piggy-back technique. Both transplants functioned well initially. The auxiliary liver was rejected after 1 ½ months, and the patient died after an attempt at retransplantation many months later. The recipient of the orthotopic liver has perfect liver function 10 months postoperatively. PMID:10147625

ABSTRACT Background: The criterion of Milan (CM) has been used as standard for indication of liver transplantation (LTx) for hepatocellular carcinoma (HCC) worldwide for nearly 20 years. Several centers have adopted criteria expanded in order to increase the number of patients eligible to liver transplantation, while maintaining good survival rates. In Brazil, since 2006, the criterion of Milan/Brazil (CMB), which disregards nodules <2 cm, is adopted, including patients with a higher number of small nodules. Aim: To evaluate the outcome of liver transplantation within the CMB. Methods: The medical records of patients with HCC undergoing liver transplantation in relation to recurrence and survival by comparing CM and CMB, were analyzed. Results: 414 LTx for HCC, the survival at 1 and 5 years was 84.1 and 72.7%. Of these, 7% reached the CMB through downstaging, with survival at 1 and 5 years of 93.1 and 71.9%. The CMB patient group that exceeded the CM (8.6%) had a survival rate of 58.1% at five years. There was no statistical difference in survival between the groups CM, CMB and downstaging. Vascular invasion (p<0.001), higher nodule size (p=0.001) and number of nodules >2 cm (p=0.028) were associated with relapse. The age (p=0.001), female (p<0.001), real MELD (p<0.001), vascular invasion (p=0.045) and number of nodes >2 cm (p<0.014) were associated with worse survival. Conclusions: CMB increased by 8.6% indications of liver transplantation, and showed survival rates similar to CM. PMID:28076478

Liver transplantation (LT) is the only available live-saving procedure for children with irreversible liver failure. This paper reports our experience from the follow-up of 16 Greek children with end-stage liver failure who underwent a LT. Over a period of 15 years, 16 pediatric liver recipients received follow up after being subjected to OLT (orthotopic liver transplantation) due to end-stage liver failure. Nine children initially presented with extrahepatic biliary atresia, 2 with acute liver failure after toxic mushroom ingestion, 2 with intrahepatic cholestasis, 2 with metabolic diseases and one with hepatoblastoma. Ten children received a liver transplant in the Organ Transplantation Unit of Aristotle University of Thessaloniki and the rest in other transplant centers. Three transplants came from a living-related donor and 13 from a deceased donor. Six children underwent immunosuppressive treatment with cyclosporine, mycophenolate mofetil and corticosteroids, and 7 with tacrolimus, mycophenolate mofetil and corticosteroids. Three out of 16 children died within the first month after the transplantation due to post-transplant complications. Three children presented with acute rejection and one with chronic organ rejection which was successfully managed. Five children presented with cytomegalovirus infection, 5 with Epstein-Barr virus, 2 with HSV1,2, 2 with ParvoB19 virus, 2 with varicella-zoster virus and one with C. Albicans infection. One child presented with upper gastrointestinal hemorrhage and one with small biliary paucity. A satisfying outcome was achieved in most cases, with good graft function, except for the patient with small biliary paucity who required re-transplantation. The long-term clinical course of liver transplanted children is good under the condition that they are attended in specialized centers. PMID:21589827

Liver transplantation has emerged as a life-saving treatment for several patients with acute liver failure, end stage liver disease and primary hepatic malignancies. However, long term immunosuppressive therapy aiming to reduce the risk of transplant rejection increases the incidence of several complications including malignancies. This is illustrated by the observation of a high ratio between observed and expected cases of lymphoproliferative disorders following liver transplantation. Despite a huge heterogeneity in morphological appearance of these disorders ranging from reactive-like lesions to real lymphomas, they are collectively termed posttransplant lymphoproliferative disorders. In this review we will provide an overview of this rare but challenging disorder as a complication of liver transplantation. PMID:26494960

Acute liver failure is a critical medical condition defined as rapid development of hepatic dysfunction associated with encephalopathy. The prognosis in these patients is highly variable and depends on the etiology, interval between jaundice and encephalopathy, age, and the degree of coagulopathy. Determining the prognosis for this population is vital. Unfortunately, prognostic models with both high sensitivity and specificity for prediction of death have not been developed. Liver transplantation has dramatically improved survival in patients with acute liver failure. Still, 25% to 45% of patients will survive with medical treatment. The identification of patients who will eventually require liver transplantation should be carefully addressed through the combination of current prognostic models and continuous medical assessment. The concerns of inaccurate selection for transplantation are significant, exposing the recipient to a complex surgery and lifelong immunosuppression. In this challenging scenario, where organ shortage remains one of the main problems, alternatives to conventional orthotopic liver transplantation, such as living-donor liver transplantation, auxiliary liver transplant, and ABO-incompatible grafts, should be explored. Although overall outcomes after liver transplantation for acute liver failure are improving, they are not yet comparable to elective transplantation. PMID:26819519

Hepatic vein stenosis is a rare but serious complication following liver transplantation. Multiple modalities can be utilized to image the hepatic vasculature. Magnetic resonance venography (MRV) provides certain advantages over ultrasound, computed tomography angiography and digital subtraction venography. MRV utilizes the same imaging principles of magnetic resonance angiography in order to image the venous system. Blood pool contrast agents, specifically gadofosveset trisodium, allow for steady state imaging up to 1 h following injection, with improved visualisation of vital venous structures by utilising delayed steady state imaging. Additionally, the inherent physics properties of magnetic resonance imaging also provide excellent soft tissue detail and thus help define the extent of complications that often plague the post-liver transplant patient. This case report describes the use of gadofosveset trisodium in a patient with hepatic venous stenosis following liver transplantation. Initial venography failed to outline the stenoses and thus MRV using a blood pool contrast agent was utilised in order to delineate the anatomy and plan a therapeutic endovascular procedure.

Kidney injury is associated with increased morbidity and mortality in liver transplant recipients. Since the introduction of the model for end-stage liver disease for the allocation of organs for liver transplantation in 2002, the heavy weighting of serum creatinine in the model for end-stage liver disease score has significantly increased the incidence of renal dysfunction seen among patients undergoing liver transplantation. As a result, the frequency of simultaneous liver-kidney (SLK) transplantation compared to liver transplantation alone (LTA) has also increased. The decision to perform SLK rather than LTA is an important one because the benefits to the liver transplant recipient receiving a kidney transplant must be balanced with the benefits of using that organ for a patient with end-stage renal disease. However, predicting whether or not a patient with liver failure has reversible kidney disease, and therefore does not also need a kidney transplant, is difficult. The severity and duration of pretransplant renal dysfunction, hepatitis c, diabetes, and other risk factors for kidney disease are associated with an increased risk of posttransplant end-stage renal disease. However, there are currently no clinical findings that accurately predict renal recovery post liver transplant. As a result, the rate of SLK versus LTA differs significantly between transplant centers. To increase consistency across centers, multiple guidelines have been proposed to guide the decision between SLK and LTA, but their poor predictive value has limited their uniform adoption. Nevertheless, adoption of uniform rules for the allocation of kidneys would reduce the variability between centers in rates of SLK transplant.

Transplantation for the treatment of alcoholic cirrhosis is more controversially discussed than it is for any other indication. The crucial aspect in this setting is abstinence before and after liver transplantation. We established pre-transplant selection criteria for potential transplant candidates. Provided that the underlying disease can be treated, there is no reason to withhold liver transplantation in a patient suffering from alcoholic cirrhosis. Evaluation of the patient by a multidisciplinary team, including an addiction specialist, is considered to be the gold standard. However, several centers demand a specified period of abstinence - usually 6 mo- irrespective of the specialist's assessment. The 6-mo rule is viewed critically because liver transplantation was found to clearly benefit selected patients with acute alcoholic hepatitis; the benefit was similar to that achieved for other acute indications. However, the discussion may well be an academic one because the waiting time for liver transplantation exceeds six months at the majority of centers. The actual challenge in liver transplantation for alcoholic cirrhosis may well be the need for lifelong post-transplant follow-up rather than the patient's pre-transplant evaluation. A small number of recipients experience a relapse of alcoholism; these patients are at risk for organ damage and graft-related death. Post-transplant surveillance protocols should demonstrate alcohol relapse at an early stage, thus permitting the initiation of adequate treatment. Patients with alcoholic cirrhosis are at high risk of developing head and neck, esophageal, or lung cancer. The higher risk of malignancies should be considered in the routine assessment of patients suffering from alcoholic cirrhosis. Tumor surveillance protocols for liver transplant recipients, currently being developed, should become a part of standard care; these will improve survival by permitting diagnosis at an early stage. In conclusion, the key

Objective To determine if valproic acid (VPA)-associated ALF (VPA-ALF) explains the poor outcomes following liver transplantation (LT) in children. Study design Organ Procurement and Transplantation Network data of pediatric patients who underwent LT for VPA-ALF and ALF secondary to other drugs (nonVPA- drug-induced acute liver failure [DIALF]) were analyzed. Pre- and post-transplant variables and post-LT survival were compared between VPA-ALF and nonVPA-DIALF. Results Seventeen children were transplanted for VPA-ALF. Of those, 82% died within one year of LT. Pre- and post-transplant parameters of VPA versus nonVPA-DIALF were comparable with two exceptions. Median alanine aminotransferase at transplant was remarkably lower in VPA-ALF compared with nonVPA-DIALF (45 versus 1179 IU/L, P=0.004). One-year survival probability was worse in VPA-ALF than nonVPA-DIALF (20% versus 69%, P<0.0001). Median post-LT survival time for VPA-ALF was 2.8 months. Conclusion Children who underwent LT for VPA-ALF had significantly lower survival probability than those with nonVPA-DIALF. Current data suggest that VPA-ALF in children represents an “unmasking” of mitochondrial disease. VPA-ALF should be a contraindication for LT, even in the absence of a documented mitochondrial disease. PMID:21167499

Liver transplantation, either a partial liver from a living or deceased donor or a whole liver from a deceased donor, is the only curative therapy for severe end-stage liver disease. Only one-third of those on the liver transplant waiting list will be transplanted, and the demand for livers is projected to increase 23% in the next 20 years. Consequently, organ availability is an absolute constraint on the number of liver transplants that can be performed. Regenerative therapies aim to enhance liver tissue repair and regeneration by any means available (cell repopulation, tissue engineering, biomaterials, proteins, small molecules, and genes). Recent experimental work suggests that liver repopulation and engineered liver tissue are best suited to the task if an unlimited availability of functional induced pluripotent stem (iPS)–derived liver cells can be achieved. The derivation of iPS cells by reprogramming cell fate has opened up new lines of investigation, for instance, the generation of iPS-derived xenogeneic organs or the possibility of simply inducing the liver to reprogram its own hepatocyte function after injury. We reviewed current knowledge about liver repopulation, generation of engineered livers and reprogramming of liver function. We also discussed the numerous barriers that have to be overcome for clinical implementation. PMID:26699680

The authors retrospectively reviewed the results obtained with percutaneous treatment of portal stenosis. In November 2005 and March 2008, two patients, 15 and 32 months old, underwent portal vein angioplasty at our centre. Both procedures were performed after ultrasound-guided portal vein puncture and measurement of pre- and postanastomotic pressure gradients. The diameters of the angioplasty catheters ranged from 5 to 10 mm and no stents were used. In both cases, it was possible to cross the stenoses, perform angioplasty and obtain an immediate reduction of the pressure gradients. There were no major complications after the procedure. In the first patient, percutaneous treatment allowed us to postpone surgical revision of the anastomosis; in the second case, angioplasty had to be repeated twice over a period of 4 years to finally achieve regular patency of the anastomosis and function of the graft. Percutaneous treatment of portal stenosis after paediatric liver transplantation is a safe and feasible treatment; if balloon dilatation does not guarantee functional recovery of the organ, it allows surgical revision to be postponed to a later date when the clinical condition is more stable.

The first clinical orthotopic liver transplantation in Brazil was performed on August 5, 1968. The patient was awake after surgery and died on the seventh postoperative day due to subdural hematoma, bronchopneumonia, renal failure, and graft rejection. The report of this case is important to understand the evolution of clinical liver transplantation in Brazil, where this procedure is now routinely carried out in many medical centers.

The most common identifiable causes of acute liver failure in pediatric patients are infection, drug toxicity, metabolic disease, and autoimmune processes. In many cases, the etiology of acute liver failure cannot be determined. Acute leukemia is an extremely rare cause of acute liver failure, and liver transplantation has traditionally been contraindicated in this setting. We report a case of acute liver failure in a previously healthy 15-yr-old male from pre-B-cell acute lymphoblastic leukemia. He underwent liver transplantation before the diagnosis was established, and has subsequently received chemotherapy for pre-B-cell acute lymphoblastic leukemia. He is currently alive 31 months post-transplantation. The published literature describing acute lymphoblastic leukemia as a cause of acute liver failure is reviewed. © 2014 John Wiley & Sons A/S.

In recent years, hyperbaric oxygen (HBO) has been used in the treatment of a lot of diseases such as decompression sickness, arterial gas embolism, carbon dioxide poisoning, soft tissue infection, refractory osteomyelitis, and problematic wound, but little is known about its application in liver transplantation. Although several studies have been conducted to investigate the protective effects of HBO on liver transplantation and liver preservation, there are still some controversies on this issue, especially its immunomodulatory effect. In this short review, we briefly summarize the findings supporting the application of HBO during liver transplantation (including donors and recipients). PMID:28217293

Previous case series have reported serious complications of chicken pox (CP) after pediatric liver transplantation (PLT), mainly due to visceral dissemination. The goal of our study was to determine the incidence, risk factors, and outcomes of CP after PLT. A case-control study of all CP infections in pediatric transplant recipients followed at our center from September 1993 to April 2004 was performed. Data were collected before and after infection and at the same time points in age-, gender-, and transplant year-matched controls. Potential risk factors prior to CP and adverse outcomes after infection were compared between cases and controls. Twenty (6.2%) developed CP at a median of 1.8 yr (0.6-4.8) after PLT. All CP infections were cutaneous, with no evidence of organ involvement. Twelve were hospitalized: 9 only to receive intravenous acyclovir and 3 stayed > or =2 weeks for other complications. Risk factors were not statistically different among cases and controls. Of the outcomes analyzed, cases were significantly more likely to develop non-CP infections within one year of CP than controls (Hazard Ratio = 12.6, 95% confidence interval = 3.1-51.7; P < 0.001). These infections were often bacterial and occurred long after CP infection. In conclusion, CP is uncommon after PLT and has a low likelihood of organ dissemination. No risk factors were identified. Some cases required prolonged hospitalizations. Close monitoring for the development of late bacterial infections is warranted.

Sirolimus is a potent immunosuppressive drug that began to be used in the last few years. This drug was initially used in renal transplantation but its use in other solid organ transplantations such as liver, heart, lung and pancreas, has been increasing. Sirolimus is indicated in rescue therapies and to reduce the secondary toxic effects of calcineurin inhibitors. However, this drug has been associated with infrequent but severe pulmonary toxicity and cases of interstitial pneumonitis, bronchiolitis obliterans with organizing pneumonia, and alveolar proteinosis have been described. We present the case of a male liver transplant recipient who developed interstitial pneumonitis associated with sirolimus use.

Background : The liver is the most injured organ in abdominal trauma. Currently, the treatment in most cases is non-operative, but surgery may be necessary in severe abdominal trauma with blunt liver damage, especially those that cause uncontrollable bleeding. Despite the damage control approaches in order to achieve hemodynamic stability, many patients develop hypovolemic shock, acute liver failure, multiple organ failure and death. In this context, liver transplantation appears as the lifesaving last resource Aim : Analyze the use of liver transplantation as a treatment option for severe liver trauma. Methods : Were reviewed 14 articles in the PubMed, Medline and Lilacs databases, selected between 2008-2014 and 10 for this study. Results : Were identified 46 cases undergoing liver transplant after liver trauma; the main trauma mechanism was closed/blunt abdominal trauma in 83%, and severe trauma (>grade IV) in 81 %. The transplant can be done, in this context, performing one-stage procedure (damaged organ removed with immediate transplantation), used in 72% of cases. When the two-stage approach is performed, end-to-side temporary portacaval shunt is provided, until new organ becomes available to be transplanted. If two different periods are considered - from 1980 to 2000 and from 2000 to 2014 - the survival rate increased significantly, from 48% to 76%, while the mortality decreased from 52% to 24%. Conclusion : Despite with quite restricted indications, liver transplantation in hepatic injury is a therapeutic modality viable and feasible today, and can be used in cases when other therapeutic modalities in short and long term, do not provide the patient survival chances.

Graft-versus-host-disease (GVHD) after liver transplantation (LT) is a deadly complication with very limited data on risk factors, diagnosis and management. We report a case series and a comprehensive review of the literature. Data were systematically extracted from reports of GVHD after LT, and from the United Network for Organ Sharing database. Group comparisons were performed. One hundred fifty-six adult patients with GVHD after LT have been reported. Median time to GVHD onset was 28 days. Clinical features were skin rash (92%), pancytopenia (78%), and diarrhea (65%). Six-month mortality with GVHD after LT was 73%. Sepsis was the most common cause of death (60%). Enterobacter bacteremia, invasive aspergillosis, and disseminated Candida infections were frequently reported. Recipient age over 50 years is a risk factor for GVHD after LT. Hepatocellular carcinoma was overrepresented, whereas chronic hepatitis C was underrepresented, in reported United States GVHD cases relative to all United Network for Organ Sharing database LT cases. Mortality rate with treatment of GVHD after LT was 84% with high-dose steroids alone, 75% to 100% with regimens using dose increases of calcineurin inhibitors, and 55% with IL-2 antagonists. Mortality was 25% in small case series using the CD2-blocker alefacept or TNF-α antagonists. Age older than 50 years and hepatocellular carcinoma appear to be risk factors for GVHD. Hepatitis C may be protective. High-dose steroids and calcineurin inhibitors are ineffective in the treatment of GVHD after LT. CD2-blockers and TNF-α antagonists appear promising. We propose a diagnostic algorithm to assist clinicians in managing adults with GVHD after LT.
As surgical and graft preservation techniques have improved and immunosuppressive drugs have advanced, liver transplantation (LT) is now considered the gold standard for treating patients with end-stage liver disease worldwide. However, despite the improved survival following LT, severe hemodynamic disturbances during LT remain a serious issue for the anesthesiologist. The greatest hemodynamic disturbance is postreperfusion syndrome (PRS), which occurs at reperfusion of the donated liver after unclamping of the portal vein. PRS is characterized by marked decreases in mean arterial pressure and systemic vascular resistance, and moderate increases in pulmonary arterial pressure and central venous pressure. The underlying pathophysiological mechanisms of PRS are complex. Moreover, risk factors associated with PRS are not fully understood. Rapid and appropriate treatment with vasopressors, volume replacement, or venesection must be provided depending on the cause of the hemodynamic disturbance when hemodynamic instability becomes profound after reperfusion. The negative effects of PRS on postoperative early morbidity and mortality are clear, but the effect of PRS on postoperative long-term mortality remains a matter of debate. PMID:26634075

This is the first report of living donor liver transplantation (LDLT) for congenital hepatic fibrosis (CHF) using a mother's graft with von Meyenburg complex. A 6-year-old girl with CHF, who suffered from recurrent gastrointestinal bleeding, was referred to our hospital for liver transplantation. Her 38-year-old mother was investigated as a living donor and multiple biliary hamartoma were seen on her computed tomography and magnetic resonance imaging scan. The mother's liver function tests were normal and she did not have any organ abnormality, including polycystic kidney disease. LDLT using the left lateral segment (LLS) graft from the donor was performed. The donor LLS graft weighed 250 g; the graft recipient weight ratio was 1.19%. The operation and post-operative course of the donor were uneventful and she was discharged on post-operative day (POD) 8. The graft liver function was good, and the recipient was discharged on POD 31. LDLT using a graft with von Meyenburg complex is safe and useful. Long-term follow-up is needed with respect to graft liver function and screening malignant tumors.
Liver transplantation (LT) services in the United Kingdom are provided by 7 designated transplant centers for a population of approximately 64 million. The number of deceased organ donors has grown, and in 2014-2015 it was 1282 (570 donation after circulatory death and 772 donation after brain death). Donor risk is increasing. In 2014-2015, there were 829 LTs from deceased and 38 from living donors. The common causes for transplantation are liver cell cancer, viral hepatitis, and alcohol-related liver disease. Livers are allocated first nationally to super-urgent listed patients and then on a zonal basis. The United Kingdom will be moving toward a national allocation scheme. The median interval between listing and transplantation is 152 days for adults awaiting their first elective transplant. Of the adults listed for the first elective transplant, 68% underwent transplantation at < 1 year; 17% are waiting; and 4% and 11% were removed or died, respectively. The 1- and 5-year adult patient survival rate from listing is 81% and 68%, respectively, and from transplantation is 92% and 80%, respectively. The transplant program is funded through general taxation and is free at the point of care to those who are eligible for National Health Service (NHS) treatment; some have to pay for medication (up to a maximum payment of US $151/year). The competent authority is the Human Tissue Authority which licenses donor characterization, retrieval, and implantation; transplant units are commissioned by NHS England and NHS Scotland. National Health Service Blood and Transplant (NHSBT) promotes organ donation, maintains the organ donor register, obtains consent, and undertakes donor characterization and offering. NHSBT also maintains the national waiting list, develops and applies selection and allocation policies, monitors outcomes, and maintains the UK National Transplant Registry and commissions a national organ retrieval service.

In living-donor liver transplant, hepatic venous anomalies are not rare. Despite numerous techniques developed over the years, the best way of establishing a patent and durable hepatic drainage system remains controversial. We present a case where we successfully reconstructed 5 hepatic venous structures with a combination of direct anastomosis and saphenous vein interposition. Careful planning before surgery, and a customized approach for the patient on the back table, brought about successful results.

Within the field of regenerative medicine, the liver is of major interest for adoption of regenerative strategies due to its well-known and unique regenerative capacity. Whereas therapeutic strategies such as liver resection and orthotopic liver transplantation (OLT) can be considered standards of care for the treatment of a variety of liver diseases, the concept of liver cell transplantation (LCTx) still awaits clinical breakthrough. Success of LCTx is hampered by insufficient engraftment/long-term acceptance of cellular allografts mainly due to rejection of transplanted cells. This is in contrast to the results achieved for OLT where long-term graft survival is observed on a regular basis and, hence, the liver has been deemed an immune-privileged organ. Immune responses induced by isolated hepatocytes apparently differ considerably from those observed following transplantation of solid organs and, thus, LCTx requires refined immunological strategies to improve its clinical outcome. In addition, clinical usage of LCTx but also related basic research efforts are hindered by the limited availability of high quality liver cells, strongly emphasizing the need for alternative cell sources. This review focuses on the various immunological aspects of LCTx summarizing data available not only for hepatocyte transplantation but also for transplantation of non-parenchymal liver cells and liver stem cells.

The growing discrepancy between the need and the availability of donor livers has resulted in evolving surgical approaches in liver transplantation during the last two decades to expand the donor pool. One approach is to transplant partial grafts, obtained either from a living donor or splitting a cadaveric donor liver. For both surgical methods, it is important to obtain a minimal viable graft volume to prevent small-for-size syndrome and graft failure. This minimal volume, expressed as graft-to-whole body ratio, must be between 0.8 and 1%. Living donor liver transplantation (LDLT) became the primary transplant option in many Asian countries and is increasingly performed as an adjunct transplant option in countries with low donation rates. Split liver transplantation (SLT) is a surgical method that creates two allografts from one deceased donor. The most widely used splitting technique is the division of the liver into a left lateral sectoral graft (segments 2 and 3) for a pediatric patient and a right trisegmental graft (segments 1 and 4 to 8) for an adult patient. Both LDLT and SLT are also important and established methods for the treatment of pediatric patients. Another evolving surgical approach is auxiliary liver transplantation, which describes the transplanting a whole or partial graft with preservation of the partial native liver. This bridging technique is applied in patients with fulminate liver failure and should allow the regeneration of the injured liver with the potential to discontinue immunosuppression. Other methods such as xenotransplantation, as well as hepatocyte and stem cell transplantation, are promising approaches that are still in experimental phases.

Hepatic epithelioid haemangioendotheliomas (HEHEs) are rare, low-grade vascular tumours. Five adults with HEHEs and one adult with a vascular tumour showing combined features of haemangioma and haemangioendothelioma underwent liver transplantation. Two HEHE patients had extrahepatic metastases at the time of transplantation. Median survival time following diagnosis was 10.7 years (range 40 months to 195 months). One patient needed resection of a HEHE in the breast 13 years post-transplantation. All six patients are surviving free from disease 22 to 166 months after transplantation (median 77 months). One HEHE-patient who had been treated for 8 years for vertebral and cerebral localisations is free of disease without immunosuppression 56 months after transplantation. We can conclude that liver transplantation is a valuable treatment for hepatic haemangioendothelioma, even in cases of extrahepatic localisation of the disease.

Initially considered experimental, liver transplantation (LT) has become the treatment of choice for the patients with end-stage liver diseases. Between April 2000 and October 2009, 200 LTs (10 reLTs) were performed in 190 patients, this study being retrospective. There were transplanted 110 men and 80 women, 159 adults and 31 children with the age between 1 and 64 years old (mean age--39.9). The main indication in the adult group was represented by viral cirrhosis, while the pediatric series the etiology was mainly glycogenosis and biliary atresia. There were performed 143 whole graft LTs, 46 living donor LTs, 6 split LTs, 4 reduced LTs and one domino LT RESULTS: The postoperative survival was 90% (170 patients). The patient and graft one-year and five-year survivals were 76.9%, 73.6% and 71%, 68.2%, respectively. The early complications occurred in 127 patients (67%). The late complications were recorded in 71 patients (37.3%). The intraoperative and early postoperative mortality rate was 9.5% (18 patients). The Romanian liver transplantation program from Fundeni includes all types of current surgical techniques and the results are comparable with those from other international centers.

Improved outcomes of liver transplantation have led to increases in the numbers of US transplant centers and candidates on the list. The resultant and ever-expanding organ shortage has created competition among centers, especially in regions with multiple liver transplant programs. Multiple reports now document that competition among the country's transplant centers has led to the listing of increasingly high-risk patients and the utilization of more marginal liver allografts. The transplant and medical communities at large should carefully re-evaluate these practices and promote innovative approaches to restoring trust in the allocation of donor organs and confirming that there is nationwide conformity in the guidelines used for evaluating and listing potential candidates for this scarce resource. © 2014 American Association for the Study of Liver Diseases.

OBJECTIVE: This article describes the experience with liver transplantation in patients with irresectable neuroendocrine hepatic metastases. SUMMARY BACKGROUND DATA: Liver transplantation has become an established therapy in primary liver cancer. On contrast, there is little experience with liver transplantation in secondary hepatic tumors. So far, in the majority of patients being transplanted for irresectable liver metastases, long-term results have been disappointing because of early tumor recurrence. Because of their biologically less aggressive nature, the metastases of neuroendocrine tumors could represent a justified indication for liver grafting. METHODS: In a retrospective study, the data of 12 patients who underwent liver transplantation for irresectable neuroendocrine hepatic metastases were analyzed regarding survival, tumor recurrence, and symptomatic relief. RESULTS: Nine of 12 patients currently are alive with a median survival of 55 months (range, 11.0 days to 103.5 months). The operative mortality was 1 of 12, 2 patients died because of septic complications or tumor recurrences or both 6.5 months and 68.0 months after transplantation. all patients had good symptomatic relief after hepatectomy and transplantation. Four of the nine patients who are alive have no evidence of tumor with a follow-up of 2.0, 57.0, 58.0, and 103.5 months after transplantation. CONCLUSIONS: In selected patients, liver transplantation for irresectable neuroendocrine hepatic metastases may provide not only long-term palliation but even cure. Regarding the shortage of donor organs, liver grafting for neuroendocrine metastases should be considered solely in patients without evidence of extrahepatic tumor manifestation and in whom all other treatment methods are no longer effective.

Liver transplantation in patients with liver cirrhosis, portal vein thrombosis, and cavernous transformation of the portal vein, is a complex procedure with high possibility of liver graft dysfunction. It is performed in 2-19% of all liver transplants, and has a significantly high mortality rate in the post-operative period. Other procedures to maintain portal perfusion have been described, however there are no reports of liver graft perfusion using right gastroepiploic vein. A 20 year-old female diagnosed with cryptogenic cirrhosis, with a Child-Pugh score of 7 points (class "B"), and MELD score of 14 points, with thrombosis and cavernous transformation of the portal vein, severe portal hypertension, splenomegaly, a history of upper gastrointestinal bleeding due to oesophageal varices, and left renal agenesis. The preoperative evaluation for liver transplantation was completed, and the right gastroepiploic vein of 1-cm diameter was observed draining to the infrahepatic inferior vena cava and right suprarenal vein. An orthotopic liver transplantation was performed from a non-living donor (deceased on January 30, 2005) using the Piggy-Back technique. Portal vein perfusion was maintained using the right gastroepiploic vein, and the outcome was satisfactory. The patient was discharged 13 days after surgery. Liver transplantation was performed satisfactorily, obtaining an acceptable outcome. In this case, the portal perfusion had adequate blood flow through the right gastroepiploic vein.

Hepatic venous outflow obstruction following liver transplantation is rare but disastrous. Here we described a 14-year-old boy who underwent a split right lobe liver transplantation with modified (side-to-side) piggyback technique which resulted in hepatic venous outflow obstruction. When the liver graft was lifted up, the outflow drainage returned to normal but when it was placed back into the abdomen, the outflow obstruction recurred. Because reanastomosis would have resulted in hepatic reischemia, alternatively, a second infrahepatic cavocavostomy was planned without requiring hepatic reischemia. During this procedure, the first assistant hung the liver up to provide sufficient outflow and the portal inflow of the graft continued as well. We only clamped the recipient's infrahepatic vena cava and the caudal cuff of the graft cava. After the second end-to-side cavocaval anastomosis, the graft was placed in its orthotopic position and there was no outflow problem anymore. The patient tolerated the procedure well and there were no problems after three months of follow-up. A second cavocavostomy can provide an extra bypass for some hepatic venous outflow problems after piggyback anastomosis by avoiding hepatic reischemia. PMID:24959369

During this procedure, the first assistant hung the liver up to provide sufficient outflow and the portal inflow of the graft continued as well. We only clamped the recipient's infrahepatic vena cava and the caudal cuff of the graft cava. After the second end-to-side cavocaval anastomosis, the graft was placed in its orthotopic position and there was no outflow problem anymore. The patient tolerated the procedure well and there were no problems after three months of follow-up. A second cavocavostomy can provide an extra bypass for some hepatic venous outflow problems after piggyback anastomosis by avoiding hepatic reischemia.

Two patients with primary hepatic malignancy were treated by hepatectomy and orthotopic liver transplantation. In both cases the donor liver was infused with cold solutions and kept chilled without continuous perfusion. There was immediate satisfactory hepatic function in both transplants. The first patient died after 11 weeks from overwhelming bacterial and fungal infections probably secondary to hepatic infarction due to thrombosis of the recipient hepatic artery. The thrombus occurred at the site of the arterial clamp. In an attempt to control the growth before transplantation, the patient had been treated with large doses of chlorambucil, which resulted in extreme marrow depression and septicaemia. The second patient developed cholestatic jaundice during the second and third weeks after transplantation, with histological evidence of mild rejection, which was controlled by increasing the dose of immunosuppressive agents. He is now well, having returned to work six weeks after the operation. Though the first patient showed no evidence of rejection, it is concluded that patients receiving liver allografts should receive immunosuppressive therapy.

Multiple myeloma (MM) represents a rare form of post-transplantation lymphoproliferative disorder, and the presence of plasma cells in the liver is generally associated with aggressive forms of MM. In the present study, an unusual case of extramedullary plasmacytoma, affecting the liver and vertebrae of a recipient of a renal transplant, is reported. The patient had been previously treated with bortezomib for an MM following renal transplantation, as diagnosed by percutaneous needle biopsy of the hepatic lesion. He was then treated with 5 cycles of RCD regimen (lenalidomide, 25 mg, days 1–21; cyclophosphamide. 50–100 mg, days 1–21; and dexamethasone, 20 mg, days 1, 8, 15 and 22). The patient achieved partial clinical remission without any severe therapy-associated toxicity effects, indicating that lenalidomide is an effective and safe treatment for extramedullary liver plasmacytoma in renal recipients. In conclusion, the present case study indicated that the RCD regimen was effective and safe in the treatment of relapsed and refractory MM. PMID:26722266

Chronic liver disease has an important effect on nutritional status, and malnourishment is almost universally present in patients with end-stage liver disease who undergo liver transplantation. During recent decades, a trend has been reported that shows an increase in number of patients with end-stage liver disease and obesity in developed countries. The importance of carefully assessing the nutritional status during the work-up of patients who are candidates for liver replacement is widely recognised. Cirrhotic patients with depleted lean body mass (sarcopenia) and fat deposits have an increased surgical risk; malnutrition may further impact morbidity, mortality and costs in the post-transplantation setting. After transplantation and liver function is restored, many metabolic alterations are corrected, dietary intake is progressively normalised, and lifestyle changes may improve physical activity. Few studies have examined the modifications in body composition that occur in liver recipients. During the first 12 mo, the fat mass progressively increases in those patients who had previously depleted body mass, and the muscle mass recovery is subtle and non-significant by the end of the first year. In some patients, unregulated weight gain may lead to obesity and may promote metabolic disorders in the long term. Careful monitoring of nutritional changes will help identify the patients who are at risk for malnutrition or over-weight after liver transplantation. Physical and nutritional interventions must be investigated to evaluate their potential beneficial effect on body composition and muscle function after liver transplantation.

The disbalance between the number of candidates to liver transplant and the number of liver grafts leads to waiting list mortality. Two potential ways of increasing the number of liver grafts are split liver transplantation and the transplantation of grafts from non-heart beating donors. Both of them were discussed in a consensus meeting of the Spanish Society of Liver Transplantation in October 2012. This paper outlines the conclusions of that meeting.

Liver transplantation (LT) is a life-saving treatment for patients with end-stage liver disease and for patients with liver cell cancer related to liver disease. Acute and chronic liver diseases related to hepatitis viruses are between the main indications for liver transplantation. The risk of viral reinfection after transplantation is the main limiting factor in these indications. Before the availability of antiviral prophylaxis, hepatitis B virus (HBV) recurrence was universal in patients who were HBV DNA-positive before transplantation. The natural history of recurrent HBV was accelerated by immunosuppression, and it progressed rapidly to graft failure and death. Introduction of post-transplant prophylaxis with immunoglobulin alone first, and associated to antiviral drugs later, drastically reduced HBV recurrence, resulting in excellent long-term outcomes. On the contrary, recurrence of hepatitis C is the main cause of graft loss in most transplant programs. Overall, patient and graft survival after LT for hepatitis C virus (HCV)-associated cirrhosis is inferior compared with other indications. However, successful pretransplant or post transplant antiviral therapy has been associated with increased graft and overall survival. Until recently, the combination of pegylated interferon and ribavirin was the standard of care for the treatment of patients with chronic hepatitis C. Highly active antiviral compounds have been developed over the past decade, thanks to new in vitro systems to study HCV entry, replication, assembly, and release.

The criterion of Milan (CM) has been used as standard for indication of liver transplantation (LTx) for hepatocellular carcinoma (HCC) worldwide for nearly 20 years. Several centers have adopted criteria expanded in order to increase the number of patients eligible to liver transplantation, while maintaining good survival rates. In Brazil, since 2006, the criterion of Milan/Brazil (CMB), which disregards nodules <2 cm, is adopted, including patients with a higher number of small nodules. To evaluate the outcome of liver transplantation within the CMB. The medical records of patients with HCC undergoing liver transplantation in relation to recurrence and survival by comparing CM and CMB, were analyzed. 414 LTx for HCC, the survival at 1 and 5 years was 84.1 and 72.7%. Of these, 7% reached the CMB through downstaging, with survival at 1 and 5 years of 93.1 and 71.9%. The CMB patient group that exceeded the CM (8.6%) had a survival rate of 58.1% at five years. There was no statistical difference in survival between the groups CM, CMB and downstaging. Vascular invasion (p<0.001), higher nodule size (p=0.001) and number of nodules >2 cm (p=0.028) were associated with relapse. The age (p=0.001), female (p<0.001), real MELD (p<0.001), vascular invasion (p=0.045) and number of nodes >2 cm (p<0.014) were associated with worse survival. CMB increased by 8.6% indications of liver transplantation, and showed survival rates similar to CM. O critério de Milão (CM) vem sendo utilizado como padrão para indicação do transplante hepático (TxH) por hepatocarcinoma (HCC) em todo mundo há quase 20 anos. Diversos centros têm adotado critérios expandidos com intuito de aumentar o número de pacientes candidatos ao transplante, mantendo bons índices de sobrevida. No Brasil, desde 2006, o critério de Milão/Brasil (CMB), que desconsidera nódulos <2 cm, é adotado, incluindo pacientes com maior número de nódulos pequenos.

OBJECTIVE: The first purpose of this study is to identify the types and incidences of surgical procedures in patients who have previously undergone liver transplantation, with particular focus on the complication rates and the lengths of hospital stay. The second purpose is to present the management guidelines for patients with liver transplants at the preoperative, intraoperative, and postoperative stages of surgical procedure. SUMMARY BACKGROUND DATA: The surgical literature on this issue is scant, and with the growing liver transplant patient population it is not unlikey for any surgery specialist to have to operate on a patient who has undergone liver transplantation. METHODS: A sample of 409 patients with available hospital records, with a minimum of a 2-year follow-up, and with telephone access for interviews was chosen. Type of surgery, time from the liver transplant, hospital stay, immunosuppressive regimen, and complications were recorded. RESULTS: A large proportion of patients (24.2%) underwent some type of surgical procedure 2 to 10 years after liver transplantation. The authors demonstrate that most of the elective procedures can be safely carried out without an increased incidence of complication and without longer hospital stay than the general population. Conversely, emergent procedures are plagued by a greater incidence of complications that not only affect the function of the liver graft but may risk the life of the patient. PMID:9563551

End stage liver disease from hepatitis C is the most common indication for liver transplantation in many parts of the world accounting for up to 40% of liver transplants. Antiviral therapy either before or after liver transplantation is challenging due to side effects and lower efficacy in patients with cirrhosis and liver transplant recipients, as well as from drug interactions with immunosuppressants. Factors that may affect recurrent hepatitis C include donor age, immunosuppression, IL28B genotype, cytomegalovirus infection, and metabolic syndrome. Older donor age has persistently been shown to have the greatest impact on recurrent hepatitis C. After liver transplantation, distinguishing recurrent hepatitis C from acute cellular rejection may be difficult, although the development of molecular markers may help in making the correct diagnosis. The advent of interferon free regimens with direct acting antiviral agents that include NS3/4A protease inhibitors, NS5B polymerase inhibitors and NS5A inhibitors holds great promise in improving outcomes for liver transplant candidates and recipients.

Bile duct (BD) complications continue to be the "Achilles' heel" of liver transplantation, and the utilization of bile duct drainage is still on debate. We describe the results of a less invasive rubber trancystic biliary drainage (TBD) compared to a standard silicone T-tube (TT). The transplanted patients (n = 248), over a period of 5 years with a TBD (n = 20), were matched 1:2 with control patients with a TT (n = 40). Primary end points were the overall incidence of BD complications and graft and patient survival. Secondary end points included the complications after the drainage removal. Although the bile duct leakage rates were not significantly different between both groups, the TT group had a significantly higher rate of overall 1-year BD stenosis (40 versus 10 %) (p = 0.036). Three-year patient/graft survival rates were 83.2/80.1 and 84.4/84.4 % for the TT and TBD groups, respectively. The postoperative BD complications, after drainage removal (peritonitis and stenosis), were significantly reduced (p = 0.011) with the use of a TBD. The use of rubber TBD in liver transplant recipients does not increase the number of BD complications compared to the T-tube. Furthermore, less BD anastomotic stenosis and post-removal complications were observed in the TBD group compared to the TT group.

Herein, we describe an extremely rare experience of a patient with liver cirrhosis from hepatitis C virus (LC-HCV) who underwent an ABO-incompatible living donor liver transplantation (ABO-I-LDLT) using a hepatitis B core antibody (HBc-Ab) positive donor's liver graft. A 47-year-old Japanese woman with end stage LC-HCV, as a recipient, was preoperatively administered rituximab, mycophenolate mofetil, and steroids without plasma exchange. A routine ABO-I-LDLT procedure was applied using her daughter's HBc-Ab positive liver graft. Prophylaxis of the hepatitis B virus (HBV) infection using hepatitis B immunoglobulin (HBIG) and entecavir had been properly administered. Three months after the ABO-I-LDLT, HCV hepatitis relapsed. To date, this patient has been under antiviral therapy and prophylaxis of HBV infection using HBIG, while entecavir has been continued. The cognitions and techniques with regard to ABO-I-LDLT, prophylaxis of HBV cross infection, various patterns of immunosuppression, and antiviral therapy for HCV relapse are indispensable in managing a transplant recipient. According to the prophylaxis of HBV cross infection under ABO-I-LDLT, it may be very important to keep the HBs-Ab titer higher than usual for HBV naïve recipients, because severe systemic immunosuppression can cause de novo hepatitis.

The success rate of pediatric liver transplantation has improved in recent years. Advances in immunosuppression have reduced the risk of rejection, but have enhanced the risk of posttransplant lymphoproliferative disorder (PTLD). Since 1994, we have performed 197 orthotopic liver transplantations in 157 recipients younger than 15 years. Herein we have performed a retrospective study to review the incidence and clinical characteristics, along with the treatment and outcomes of PTLD diagnosed over this 14-year experience. We documented 8 cases of PTLD (5%), half of which occurred during the first 2 years posttransplantation; 5 presented with abdominal involvement and 2 with thoracic masses. The histological findings showed lymphoma in 6 cases. All were treated with reduction of immunosuppression and 2 received Rituximab. Three patients died, a mortality rate of 37.5%. One subject experienced rejection, and the others responded to treatment. PTLD is a life-threatening condition that requires a high index of suspicion, appropriate imaging, biopsy diagnosis, and prompt treatment to achieve positive results. Quantitative monitoring of Epstein-Barr virus load may be useful to detect a high-risk population.
Living donor liver transplant (LDLT) accounts for a small volume of the transplants in the USA. Due to the current liver allocation system based on the model for end-stage liver disease (MELD), LDLT has a unique role in providing life-saving transplantation for patients with low MELD scores and significant complications from portal hypertension, as well as select patients with hepatocellular carcinoma (HCC). Donor safety is paramount and has been a topic of much discussion in the transplant community as well as the general media. The donor risk appears to be low overall, with a favorable long-term quality of life. The latest trend has been a gradual shift from right-lobe grafts to left-lobe grafts to reduce donor risk, provided that the left lobe can provide adequate liver volume for the recipient.

Liver transplantation (LT) is a major surgery performed on patients with end stage liver disease. Nutrition is an integral part of patient care, and protein-energy malnutrition is almost universally present in patients suffering from liver disease undergoing LT. Nutrition assessment of preliver transplant phase helps to make a good nutrition care plan for the patients. Nutrition status has been associated with various factors which are related to the success of liver transplant such as morbidity, mortality, and length of hospital stay. To assess the nutritional status of preliver transplant patients, combinations of nutrition assessment methods should be used like subjective global assessment, Anthropometry mid arm-muscle circumference, Bioelectrical impedance analysis (BIA) and handgrip strength.

We analyzed the influence of two variables (place of hospitalization of the patients and the mental health of relatives) on symptoms of anxiety and depression in liver transplant patients. The subject groups were made up of 48 liver transplant recipients (mean age 51.15; SD = 8.57) and their close relatives. The tests applied were a psychosocial questionnaire, and the two tests: "The Hospital Anxiety and Depression Scale" and "The Leeds Scales for the Self-Assessment of Anxiety and Depression." The liver transplant recipients showed more symptoms of depression when they were in the intensive care unit (ICU) and more symptoms of anxiety in the post-ICU phase when their close relatives were more depressed in that phase. The place of hospitalization of the patients and the mental health of relatives influenced the symptoms of anxiety and depression in liver transplant recipients.

A successful liver transplantation team consists of several specialists to work closely together. The histopathologist (anatomical pathologist) is one of the key players in this multidisciplinary team. This role starts with the pre-transplantation evaluation of the recipient’s liver by diagnosis or confirming the underlying liver disease and continues with the evaluation of the explanted recipient’s liver for any further information about the underlying liver disease including malignancies such as hepatocellular carcinoma, cholangiocarcinoma, or any other incidental findings. The evaluation of the new donor liver begins with determining the suitability of the donor liver for transplantation during or before the operation and continues throughout the entire post-transplantation period by evaluating not only the allograft diseases but also evaluating other tissues for infections, malignancies, etc. It is worthy to note that in many of the above-mentioned situations, histopathology is the gold-standard diagnostic test. In this review, we present on various tasks of a histopathologist according to the current literature and our own experience in the largest liver transplantation center in Iran. PMID:28299022

We investigated the diversity of central nervous system complications after liver transplantation in terms of clinical manifestations and temporal course. Liver transplantation is a lifesaving option for end stage liver disease patients but post-transplantation neurologic complications can hamper recovery. Between 1 January 2001 and 31 December 2010, patients who had undergone liver transplantation at a single tertiary university hospital were included. We reviewed their medical records and brain imaging data and classified central nervous system complications into four categories including vascular, metabolic, infectious and neoplastic. The onset of central nervous system complications was grouped into five post-transplantation intervals including acute (within 1 month), early subacute (1-3 months), late subacute (3-12 months), chronic (1-3 years), and long-term (after 3 years). During follow-up, 65 of 791 patients (8.2%) experienced central nervous system complications, with 30 occurring within 1 month after transplantation. Vascular etiology was the most common (27 patients; 41.5%), followed by metabolic (23; 35.4%), infectious (nine patients; 13.8%), and neoplastic (six patients). Metabolic encephalopathy with altered consciousness was the most common etiology during the acute period, followed by vascular disorders. An initial focal neurologic deficit was detected in vascular and neoplastic complications, whereas metabolic and infectious etiologies presented with non-focal symptoms. Our study shows that the etiology of central nervous system complications after liver transplantation changes over time, and initial symptoms can help to predict etiology.

There are no published accounts of patients with ventriculoperitoneal shunts undergoing liver transplantation in the literature. Because patients with ventriculoperitoneal shunts are prone to infections, this may be a theoretical contraindication to transplantation. We present a case of a patient with cirrhosis who had a ventriculoperitoneal shunt placed many years prior to transplantation. The patient had no neurological complications and the shunt was intact and functioning. Prior to transplantation, the patient underwent a ventriculoperitoneal to ventriculopleural shunt conversion that was reversed posttransplantation. Apart from some minor complications, the patient has done remarkably well from a graft and neurological perspective. In conclusion, patients who have ventriculoperitoneal shunts may be considered for liver transplantation as the risk of infectious and neurological complications is low and there are no deleterious effects on graft survival.

Liver transplantation has been used in treatment of transthyretin amyloidosis, and some patients undergo domino liver transplantation (DLT) with explanted liver being transplanted to another patient with liver failure as the liver is otherwise usually functionally normal. Until end of 2015, there were 1154 DLT performed worldwide. DLT for transthyretin amyloidosis is associated with the risk of developing de novo systemic amyloidosis and amyloid neuropathy, and the risk may be greater with some non-Val30Met mutations. De novo amyloid neuropathy has been described in up to 23% of transplant recipients. Neuropathy may be preceded by asymptomatic amyloid deposition in various tissues and symptoms of neuropathy started after a median of 7 years following DLT (5.7 ± 3.2 years; range 2 mo to 10 years). Typical initial symptoms include neuropathic pain and sensory loss, while dysautonomia usually starts later. Progression of neuropathy may necessitate liver re-transplantation, and subsequent improvement of neuropathy has been reported in some patients. Explant allograft recipients need close monitoring for signs of systemic amyloidosis, neuropathy and dysautonomia as progressive symptoms may require re-transplantation. PMID:28217248

Cytomegalovirus (CMV) infection is known to be the most frequently viral infection among patients after liver transplantation. This is especially true in pediatric living-donor liver transplantation because the recipients have often not been infected with CMV and postoperative primary infection with CMV frequently occurs. Of 93 patients who underwent pediatric liver transplantation at our department, 33 patients (36.3%) were diagnosed with CMV infection using the antigenemia method (C7-HRP). Retrospective review and statistical analysis were conducted to confirm risk factors of post-transplantation CMV infection. Positive lymphocytes were diagnosed between postoperative days 8 and 111 after transplantation. Ganciclovir or foscavir were administrated to 21 patients. The other 10 patients who had one positive lymphocyte were observed and the cell disappeared on follow-up examination. We did not observe any cases of positive lymphocytes with C7-HRP in patients who received a graft from a CMV antibody-negative donor. Independent predictors associated with CMV infection in the multivariable analysis were administration of OKT3 and grafts from CMV antibody-positive donors. In CMV infection after pediatric liver transplantation, cases with CMV antibody-positive donors and with OKT3 administration for acute rejection are considered high risk, and cases with CMV antibody-negative donors are considered low risk.

HPS is a major complicating feature of end-stage liver disease. Diagnosis is clinical, and LT is the only definitive treatment. While the general impression is that HPS improves quickly after transplantation, it may not always be the case. We describe the smallest reported child with HPS prior to LT and requiring prolonged venoarterial extracorporeal membrane oxygenation after LT; especially as it is a rare occurrence, physician managing such cases should be aware of the circumstances under which HPS may require specific treatment. © 2017 John Wiley & Sons A/S.

Liver transplant is the unique curative therapy for patients with acute liver failure or end-stage liver disease, with or without hepatocellular carcinoma. Increase of body weight, onset of insulin resistance and drug-induced alterations of metabolism are reported in liver transplant recipients. In this context, post-transplant diabetes mellitus, hyperlipidemia, and arterial hypertension can be often diagnosed. Multifactorial illnesses occurring in the post-transplant period represent significant causes of morbidity and mortality. This is especially true for metabolic syndrome. Non-alcoholic steatosis and steatohepatitis are hepatic manifestations of metabolic syndrome and after liver transplant both recurrent and de novo steatosis can be found. Usually, post-transplant steatosis shows an indolent outcome with few cases of fibrosis progression. However, in the post-transplant setting, both metabolic syndrome and steatosis might play a key role in the stratification of morbidity and mortality risk, being commonly associated with cardiovascular disease. The single components of metabolic syndrome can be treated with targeted drugs while lifestyle intervention is the only reasonable therapeutic approach for transplant patients with non-alcoholic steatosis or steatohepatitis.

The number of liver grafts obtained from a cadaver can be greatly increased with the application of split liver transplantation. In the last 10 years, pediatric waiting list mortality has been reduced significantly with the use of this form of liver transplantation, which has 2 major forms. In its most commonly used form, the liver can be transplanted into 1 adult and 1 child by splitting it into a right extended and a left lateral graft. For adult and pediatric recipients, the results of this procedure are comparable to those of whole-organ techniques. In another form, 2 hemi-grafts are obtained by splitting the liver, which can be transplanted into a medium-sized adult (the right side) and a large child/small adult (the left side). The adult liver graft pool is expanded through the process of full right/full left splitting; but it is also a critical technique when one considers the knowledge required of the potential anatomic variations and the high technical skill level needed. In this review, we provide some basic insights into the technical and anatomical aspects of these 2 forms of split liver transplantation and present an updated summary of both forms.

Despite advances in immunosuppression and liver transplant in the past, mortality and morbidity caused by infections remain major problems. We present a 71-year-old man who was admitted to our internal intensive care unit with septicemia. Upon admission, he had poorly localized epigastric pain and fever of 2 days ' duration. Twenty years earlier, he had undergone an orthotopic liver transplant. Testing revealed a high C-reactive protein level, elevated liver enzymes, and an acute kidney injury. A computer tomography scan showed 2 circular, non--rim-enhancing, totally emphysematous intrahepatic lesions. Additionally, gas could be seen in the portal veins mainly, as well as in the biliary system, in the right auricle, and the splenic veins. To the best of our knowledge, he showed no malignant lesion or predisposing trauma. Empirically, treatment with broad-spectrum antibiotics was begun, and the patient was transferred to the operating suite. When surgery began, blood cultures revealed the presence of gram-positive bacilli, which were identified as Clostridium perfringens. Seven hours after the surgery, the patient developed asystole and died. In septic patients presenting with severe hemolysis, Clostridium perfringens infection must be considered in the absence of a malignant lesion or a predisposing trauma; a previous episode of gastroenteritis might be a predisposing trauma by impairing the barrier of the intestinal flora, leading to Clostridium perfringens infection.

Portal vein thrombosis (PVT) is a common complication in patients with liver cirrhosis. During liver transplantation (LT), PVT may complicate the procedure and lead to a poor prognosis. The aim of this study is to evaluate patients enrolled in the China Liver Transplant Registry, to understand the influence of PVT to the LT recipients. We collected data from patients who underwent LT and were entered into the China Liver Transplant Registry. All data of medical records and follow-up were retrospectively reviewed. The preoperative condition, duration of surgery, intraoperative blood loss, postoperative early and late PVT, and survival rates were compared between patients with PVT and those without PVT. Multivariate Cox analysis and survival analysis were used to determine the influence of PVT. A total of 20,524 cases were recruited into the study. In all, 1810 (8.82%) patients were diagnosed with preoperative PVT of various severities. All patients were followed up for an average of 30.25±33.25months (up to a maximum of 171.68months). Patients with PVT had a significantly longer operating time, more intraoperative blood loss and a higher rate of post-LT PVT (P<0.001). Multivariate Cox analysis showed that PVT did not reduce the recipients' survival rate (HR=0.89, 95% CI: 0.774-1.024, P=0.103). There was no significant difference in cumulative survival rate (P=0.059) between patients without PVT, and patients with PVT. PVT increases the difficulty of LT, but doesn't reduce the survival rate. Therefore, PVT is not an absolute contraindication for LT in experienced transplantation centers. Copyright © 2016.

Polycystic liver disease (PLD) is a hereditary disease inherited by autosomal dominant trait that occurs as a frequent extrarenal manifestation of autosomal dominant polycystic kidney disease (ADPKD). We report a case of a 59-year-old woman diagnosed with ADPKD associated with PLD. End-stage chronic renal failure with a secondary Budd-Chiari syndrome developed during the patient's clinical course. She underwent combined liver and kidney transplantation, with a successful response over a 9-year follow-up period. PMID:24987537

A clinical case of epithelioid hemangioendothelioma without extrahepatic involvement treated with liver transplantation is presented. The patient remains alive 42 months thereafter without tumor recurrence. A review of cases reported to date was carried out with special reference being made to the therapy undertaken and the follow-up.
Intraoperative thromboembolism is a well-documented complication associated with orthotopic liver transplantation (OLT) but its identification and intraoperative treatment are still an emerging topic in anesthesia. Intracardiac thrombus during OLT is associated with a high mortality rate. There are only a few reports describing the successful management of thromboembolism during OLT. We describe a case where routine intraoperative transesophageal echocardiography during a live donor liver transplantation enabled early detection of an intracardiac thrombus with subsequent successful heparin treatment. Our case suggests that if an intracardiac thrombus is identified early (before hemodynamic instability occurs), the use of IV heparin may be a safe therapeutic option. PMID:28070442

Cytomegalovirus (CMV) infection in patients with liver transplantation (LT) remains a highly prevalent complication with a significant increase in morbidity and mortality. However, CMV-associated meningoencephalitis is rarely diagnosed, and treatment is very difficult. The aim of the present report is to review the experience of successful treatment with combined ganciclovir and foscarnet of CMV-associated meningoencephalitis refractory to ganciclovir alone in a hemodialysis (HD) patient after LT. A 54-year-old woman with end-stage renal disease on HD developed a seizure with loss of consciousness. She had received a liver transplant 4 months before. Blood CMV polymerase chain reaction was positive, and cerebrospinal fluid (CSF) analysis was compatible with viral meningitis. Brain magnetic resonance imaging (MRI) showed extensive dural thickening with enhancement and a round ring-like enhancement in the left centrum semiovale. She was diagnosed with CMV-associated meningoencephalitis. At that time, ganciclovir was started intravenously. After that, there were no improvements in mental state, CSF analysis, or brain MRI. Intravenous foscarnet at reduced dose was added to ganciclovir therapy. With combined ganciclovir and foscarnet, there was a slight improvement in her mental state and brain MRI.

Anesthetic management of pediatric liver transplantation in a patient with osteogenesis imperfecta (OI) requires tough decisions and comprehensive considerations of the cascade of effects that may arise and the required monitoring. Total intravenous anesthesia (TIVA) with propofol and remifentanil was chosen as the main anesthetic strategy. Malignant hyperthermia (MH), skeletal fragility, anhepatic phase during liver transplantation, uncertainties of TIVA in children, and propofol infusion syndrome were considered and monitored. There were no adverse events during the operation. Despite meticulous precautions with regard to the risk of MH, there was an episode of high fever (40℃) in the ICU a few hours after the operation, which was initially feared as MH. Fortunately, MH was ruled out as the fever subsided soon after hydration and antipyretics were given. Although the delivery of supportive care and the administration of dantrolene are the core principles in the management of MH, perioperative fever does not always mean a MH in patients at risk for MH, and other common causes of fever should also be considered.

Protein-energy malnutrition is frequently seen in patients with end-stage liver disease who undergo liver transplantation. This causes a deterioration of the patients' clinical condition and affects their post-transplantation survival. Accurate assessment of the nutritional status and adequate intervention are prerequisites for perioperative nutritional treatment. However, the metabolic abnormalities induced by liver failure make the traditional assessment of the nutritional status difficult. The methods that were recently developed for accurately assessing the nutritional status by body bioelectrical impedance may be implemented in pre-transplant management. Because preoperative malnutrition and the loss of skeletal muscle mass, called sarcopenia, have a significant negative impact on the post-transplantation outcome, it is essential to provide adequate nutritional support during all phases of liver transplantation. Oral nutrition is preferred, but tube enteral nutrition may be required to provide the necessary caloric intake. We herein discuss both bioelectrical impedance and the latest findings in the current perioperative nutritional interventions in liver transplant patients regarding synbiotics, micronutrients, branched-chain amino acid supplementation, the use of immune system modulating formulas, the fluid balance and the offering of nocturnal meals.

Strictures of the bile duct are a well-recognized complication of liver transplant and account for more than 50% of all biliary complications after deceased donor liver transplant and living donor liver transplant. Biliary strictures that develop after transplant are classified as anastomotic strictures or nonanastomotic strictures, depending on their location in the bile duct. The incidence, etiology, natural history, and response to therapy of the 2 types vary greatly, so their distinction is clinically important. The imaging modality of choice for the diagnosis of biliary strictures is magnetic resonance cholangiopancreatography because of its high rate of diagnostic accuracy and limited risk of complications. Biliary strictures that develop after liver transplant may be managed with endoscopic retrograde cholangiography (ERC), percutaneous transhepatic cholangiography (PTC), or surgical revision, including retransplant. The initial treatment of choice for these strictures is ERC with progressive balloon dilation and the placement of increasing numbers of plastic stents. PTC and surgery are generally reserved for failures of endoscopic therapy or for anatomic variants that are not suitable for ERC. In this article, we discuss the classification of biliary strictures, their diagnosis, and the therapeutic strategies that can be used to manage these common complications of liver transplant.

Over 45 months, 119 angiographic examinations were performed in 95 patients prior to liver transplantation, and 53 examinations in 44 patients after transplantation. Transplantation feasibility was influenced by patency of the portal vein and inferior vena cava. Selective arterial portography, wedged hepatic venography, and transhepatic portography were used to assess the portal vein if sonography or computed tomography was inconclusive. Major indications for angiography after transplantation included early liver failure, sepsis, unexplained elevation of liver enzyme levels, and delayed bile leakage, all of which may be due to hepatic artery thrombosis. Other indications included gastrointestinal tract bleeding, hemobilia, and evaluation of portal vein patency in patients with chronic rejection who were being considered for retransplantation. Normal radiographic features of hepatic artery and portal vein reconstruction are demonstrated. Complications diagnosed using results of angiography included hepatic artery or portal vein stenoses and thromboses and pancreaticoduodenal aneurysms. Intrahepatic arterial narrowing, attenuation, slow flow, and poor filling were seen in five patients with rejection PMID:3901102

Living donor liver transplantation (LDLT) sparked significant interest in Europe when the first reports of its success from USA and Asia were made public. Many transplant programs initiated LDLT and some of them especially in Germany and Belgium became a point of reference for many patients and important contributors to the advancement of the field. After the initial enthusiasm, most of the European programs stopped performing LDLT and today the overall European activity is concentrated in a few centers and the number of living donor liver transplants is only a single digit fraction of the overall number of liver transplants performed. In this paper we analyse the present European activities and highlight the European contribution to the advancement of the field of LDLT. PMID:27115011

Patient: Female, 54 Final Diagnosis: Suprahepatic inferior vena cava anastomosis stricture Symptoms: Ascites • fatigue • lower limb edema • hepatomegaly Medication: — Clinical Procedure: — Specialty: Transplantology • Critical Care Medicine Objective: Unusual clinical course Background: Suprahepatic inferior vena cava anastomosis stricture is an unusual vascular complication after orthotopic liver transplantation with the “piggyback” technique. Clinical manifestations are dependent upon the severity of the stenosis. Portopulmonary hypertension after orthotopic liver transplantation is a complication that carries high mortality due to cardiopulmonary dysfunction. The pathogenesis of pulmonary vascular disorders after orthotopic liver transplantation remains uncertain. Case Report: We report a case of acute right heart pressure overload after surgical correction of the suprahepatic inferior vena cava anastomotic stricture in a 54-year-old woman who had preexisting pulmonary arterial hypertension associated with portal hypertension after orthotopic liver transplantation. Twenty months posttransplantation, she developed fatigue and progressive ascites. On admission, the patient had hepatomegaly, ascites, and lower limb edema. Symptoms in the patient developed gradually over time. Conclusions: Recurrent portal hypertension by vascular complications is a cause of pulmonary arterial hypertension after orthotopic liver transplantation. Clinical manifestations of suprahepatic inferior vena cava anastomotic stenosis are dependent upon their severity. Sildenafil is an effective drug for treatment of pulmonary arterial hyper-tension after portal hypertension by vascular complications. PMID:24046802

We report a transplant of the left lateral liver segments with 3 arteries for a pediatric recipient from a living donor. A 6-month-old female infant was diagnosed with liver cirrhosis secondary to biliary atresia and scheduled for living donor liver transplantation (LDLT; mother as donor). Left lateral hepatectomy was performed at the donor site. The dissection of the left hepatic artery (HA), which was divided immediately after its origin, showed 3 branches for segments II, III, and IV. The arteries for segment II, segment III, and segment IV were anastomosed to the recipient HA. No postoperative complications were observed. The outcome of this case demonstrates that left lateral segments with 3 arteries can be successfully used if proper surgical techniques are applied. From this experience we can recommend "3-in-1 segmental resection" in the donor can be safely done by skilled microvascular surgeons and this technique should be considered for selected cases where multiple tiny arteries supply the graft.

Continued advances in surgical techniques and immunosuppressive therapy have allowed liver transplantation to become an extremely successful treatment option for patients with end-stage liver disease. Beginning with the revolutionary discovery of cyclosporine in the 1970s, immunosuppressive regimens have evolved greatly and current statistics confirm one-year graft survival rates in excess of 80%. Immunosuppressive regimens include calcineurin inhibitors, anti-metabolites, mTOR inhibitors, steroids and antibody-based therapies. These agents target different sites in the T cell activation cascade, usually by inhibiting T cell activation or via T cell depletion. They are used as induction therapy in the immediate peri- and post-operative period, as long-term maintenance medications to preserve graft function and as salvage therapy for acute rejection in liver transplant recipients. This review will focus on existing immunosuppressive agents for liver transplantation and consider newer medications on the horizon. PMID:19750565

Posttransplant lymphoproliferative disorders (PTLD) are a life-threatening complication following solid organ transplantation. Many posttransplant lymphomas develop from the uncontrolled proliferation of Epstein-Barr virus (EBV)-infected B-cells, whereas EBV-negative PTLDs were increasingly recognized within the past decade. Major risk factors for the development of PTLDs after liver transplantation are immunosuppressive therapy and the type of underlying disease: viral hepatitis, autoimmune liver disease, or alcoholic liver cirrhosis contribute to an increased risk for PTLD. Therapeutic regimens include reduction of immunosuppression, the anti-CD20 antibody rituximab, and chemotherapy, as well as new approaches using interferon-α and anti-interleukin-6 antibodies. Despite the different therapeutic regimens, mortality from PTLD remains high. Therefore, it is of major importance to identify patients at risk at an early stage of the disease. In this review, risk factors for PTLD development after liver transplantation, clinical presentation, diagnosis, and therapy are discussed.

Utilizing the opened round ligament as venous grafts during liver transplantation is useful but controversial, and there are no pathological analyses of this procedure. Herein, we describe the first reported case of a pathological analysis of an opened round ligament used as a venous patch graft in a living donor liver transplantation (LDLT). A 13-year-old female patient with biliary atresia underwent LDLT using a posterior segment graft from her mother. The graft had two hepatic veins (HVs), which included the right HV (RHV; 15 mm) and the inferior RHV (IRHV; 20 mm). The graft RHV and IRHV were formed into a single orifice using the donor’s opened round ligament (60 mm × 20 mm) as a patch graft during bench surgery; it was then anastomosed end-to-side with the recipient inferior vena cava. The recipient had no post-transplant complications involving the HVs, but she died of septic shock with persistent cholangitis and jaundice 86 d after LDLT. The HV anastomotic site had no stenosis or thrombus on autopsy. On pathology, there was adequate patency and continuity between the recipient’s HV and the donor’s opened round ligament. In addition, the stains for CD31 and CD34 on the inner membrane of the opened round ligament were positive. Hepatic venous reconstruction using the opened round ligament as a venous patch graft is effective in LDLT, as observed on pathology. PMID:27678368

Liver failure is a heterogeneous condition which may be fatal and the primary cause is frequently unknown. We investigated mitochondrial oxidative phosphorylation in patients undergoing liver transplantation. We studied 45 patients who had liver transplantation due to a variety of clinical presentations. Blue native polyacrylamide gel electrophoresis with immunodetection of respiratory chain complexes I-V, biochemical activity of respiratory chain complexes II and IV and quantification of mitochondrial DNA (mtDNA) copy number were investigated in liver tissue collected from the explanted liver during transplantation. Abnormal mitochondrial function was frequently present in this cohort: ten of 40 patients (25 %) had a defect of one or more respiratory chain enzyme complexes on blue native gels, 20 patients (44 %) had low activity of complex II and/or IV and ten (22 %) had a reduced mtDNA copy number. Combined respiratory chain deficiency and reduced numbers of mitochondria were detected in all three patients with acute liver failure. Low complex IV activity in biliary atresia and complex II defects in cirrhosis were common findings. All six patients diagnosed with liver tumours showed variable alterations in mitochondrial function, probably due to the heterogeneity of the presenting tumour. In conclusion, mitochondrial dysfunction is common in severe liver failure in non-mitochondrial conditions. Therefore, in contrast to the common practice detection of respiratory chain abnormalities in liver should not restrict the inclusion of patients for liver transplantation. Furthermore, improving mitochondrial function may be targeted as part of a complex therapy approach in different forms of liver diseases.

Liver disease alters the glucose metabolism and may cause diabetes, but this condition is potentially reversible with liver transplantation (LTx). Type 1 diabetes mellitus may be coincidentally present in a LTx candidate and immunosuppressive drugs will aggravate diabetes and make its management more difficult for posttransplant. In addition, diabetes negatively influences outcome after LTx. Therefore, the question arises as to why not transplanting the pancreas in addition to the liver in selected patients suffering from both liver disease and Type 1 diabetes. We report two cases of en bloc combined liver and pancreatic transplantation, a technique originally described a decade ago in the treatment of upper abdominal malignancies but rarely used for the treatment of combined liver disease and Type 1 diabetes. Both recipients are currently liver disease-free and insulin-free more than 2 and 4 years posttransplant, respectively. Surgical, medical and immunological aspects of combined liver-pancreas transplantation are discussed in the light of the existing relevant literature.

With the growing number of patients in need of liver transplantation, there is a need for adopting new and modifying existing allocation policies that prioritize patients for liver transplantation. Policy should ensure fair allocation that is reproducible and strongly predictive of best pre and post transplant outcomes while taking into account the natural history of the potential recipients liver disease and its complications. There is wide acceptance for allocation policies based on urgency in which the sickest patients on the waiting list with the highest risk of mortality receive priority. Model for end-stage liver disease and Child-Turcotte-Pugh scoring system, the two most universally applicable systems are used in urgency-based prioritization. However, other factors must be considered to achieve optimal allocation. Factors affecting pre-transplant patient survival and the quality of the donor organ also affect outcome. The optimal system should have allocation prioritization that accounts for both urgency and transplant outcome. We reviewed past and current liver allocation systems with the aim of generating further discussion about improvement of current policies. PMID:26973389

In Europe, 30% to 50% of liver transplantations are currently due to alcoholic liver disease (ALD). In the United States, this percentage is 17.2%. Post-transplant survival and other predictors of clinical course do not differ significantly from those in other types of transplanted patients, as long as there is no relapse of drinking. However, 20%-25% of these patients lapse or relapse to heavy drinking post-operatively, which has been associated with an increased risk of liver damage and mortality. It is therefore crucial to design specific selection and follow-up strategies aimed at this particular type of patient. Several good and poor prognosis factors that could help to predict a relapse have been suggested, among them the duration of abstinence, social support, a family history of alcoholism, abuse diagnosis versus alcohol dependence, non-acceptance of diagnosis related to alcohol use, presence of severe mental illness, non-adherence in a broad sense, number of years of alcoholism, and daily quantity of alcohol consumption. In this article, we discuss these and other, more controversial factors in selecting ALD patients for liver transplantation. Abstinence should be the main goal after transplantation in an ALD patient. In this article, we review the several definitions of post-transplant relapse, its monitoring and the psychopharmacological and psychotherapeutic treatment. PMID:26494959

End-stage liver disease due to hepatitis C (HCV) and cirrhosis from alcohol (ALD) are the commonest indications for liver transplantation in the western countries. Up to one third of HCV-infected transplant candidates have a history of significant alcohol intake prior to transplantation. However, there are few data available about the possible interaction between alcohol and HCV in the post-transplant setting. Patients with both HCV and alcohol are more likely to die on the waiting list than those with ALD and HCV alone. However, after transplantation, non-risk adjusted graft and patient survival of patients with HCV + ALD are comparable to those of patients with HCV cirrhosis or ALD cirrhosis alone. In the short and medium term HCV recurrence after transplant in patients with HCV + ALD cirrhosis does not seem more aggressive than that in patients with HCV cirrhosis alone. A relapse in alcohol consumption in patients with HCV + ALD cirrhosis does not have a major impact on graft survival. The evidence shows that, as is currently practiced, HCV + ALD as an appropriate indication for liver transplantation. However, these data are based on retrospective analyses with relatively short follow-up so the conclusions must be treated with caution. PMID:21209701
Cadaveric liver transplantation in biliary atresia splenic malformation syndrome with the absence of retrohepatic inferior vena cava, preduodenal portal vein, and intestinal malrotation: a case report.

A 9-month-old female infant with biliary atresia underwent cadaveric liver transplantation due to progressive cholestatic hepatitis following a Kasai operation. She had biliary atresia splenic malformation syndrome (BASM) composed of an absent retrohepatic inferior vena cava with an azygous connection, preduodenal portal vein, polysplenia, and intestinal malrotation. A portal vein thrombosis developed on the 4th postoperative day requiring immediate treatment by thrombectomy. The patient is well with normal liver function at 3 months follow-up. Although BASM may render the transplantation more difficult, the presence of BASM is no longer a contraindication to liver transplantation.

The anesthesiologist has been recognized as an integral member of the liver transplant team, and previous studies have demonstrated that inter-anesthesiologist variability can be a driver of outcomes for high-risk patients. We hypothesized that anesthesiologist experience, defined as the number of previous liver transplants performed at our institution, the Icahn School of Medicine at Mount Sinai, would be independently associated with outcomes for liver transplant patients. Eight hundred forty-nine liver transplants performed between January 2003 and January 2013 with a total of 22 anesthesiologists were analyzed. Each transplant was assigned an incremental case number that corresponded to the number of transplants that the attending anesthesiologist had already performed at our institution. Several perioperative covariates were controlled for in the context of a generalized linear mixed effects model to detail the influence of threshold levels of the incremental case number on the primary outcome, 30-day mortality, and a secondary outcome, 30-day graft failure. Sensitivity analyses were conducted to confirm the robustness of these findings. An incremental case number ≤ 5 was associated with a significantly greater risk of 30-day mortality (odds ratio = 2.24, 95% confidence interval = 1.11-4.54, P = 0.025), and there was evidence suggestive of a greater risk of 30-day graft failure (odds ratio = 1.93, 95% confidence interval = 0.95-3.93, P = 0.071). Sensitivity analyses ruled out threats to the validity of these findings, including dropout effects and time trends in the overall performance of the transplantation unit. In conclusion, this study shows that an anesthesiologist's level of experience has a significant effect on outcomes for liver transplant recipients, with increased mortality and possibly graft failure during a provider's first 5 cases. These findings may indicate the need for increased training and supervision for

Heat illness remains a large medical burden for militaries around the world. Mitigating the incidence as well as the complications of heat illness must remain on the forefront of operational planning when operating in hot environments. We report the case of a 27-year-old male U.S. Marine who sustained a heat-related illness resulting in fulminant liver failure and permanent disability. The patient was transferred from the field to a civilian hospital. On hospital day 5, liver failure was identified. The patient was transferred to a transplant center, where he successfully received a liver transplant. 2017.
Long term outcomes after liver transplantation are major determinants of quality of life and of the value of this heroic treatment. As short term outcomes are excellent, our community is turning to take a harder look at long term outcomes. The purpose of this paper is to review these outcomes, and highlight proposed treatments, as well as pressing topics needing to be studied. A systemic review of the English literature was carried in PubMed, covering all papers addressing long term outcomes in pediatric liver transplant from 2000-2013. Late outcomes after pediatric liver transplant affect the liver graft in the form of chronic liver dysfunction. The causes include rejection particularly humoral rejection, but also de novo autoimmune hepatitis, and recurrent disease. The metabolic syndrome is a major factor in long term cardiovascular complication risk. Secondary infections, kidney dysfunction and malignancy remain a reality of those patients. There is growing evidence of late cognitive and executive function delays affecting daily life productivity as well as likely adherence. Finally, despite a good health status, quality of life measures are comparable to those of children with chronic diseases. Long term outcomes are the new frontier in pediatric liver transplantation. Much is needed to improve graft survival, but also to avoid systemic morbidities from long term immunosuppression. Quality of life is a new inclusive measure that will require interventions and innovative approaches respectful not only on the patients but also of their social circle. PMID:24511516

Great progress has been made in the field of liver transplantation over the past two decades. This progress, however, also brings up the next set of challenges: First, organ shortage remains a major limitation, and accounts for a large proportion of wait list mortality. While living donation has successfully increased the total number of liver transplants done in Asian countries, the total number of such transplants has been stagnant in the western hemisphere. As such, there has been a significant effort over the past decade to increase the existing deceased donor pool. This effort has resulted in a greater use of liver allografts following donation after cardiac death (DCD) along with marginal and extended criteria donors. Improved understanding of the pathophysiology of liver allografts procured after circulatory arrest has not only resulted in better selection and management of DCD donors, but has also helped in the development of mechanical perfusion strategies. Early outcomes demonstrating the clinical applicability of both hypothermic and normothermic perfusion and its potential to impact patient survival and allograft function have generated much interest. Second, long-term outcomes of liver transplant recipients have not improved significantly, as recipients continue to succumb to complications of long-term immunosuppression, such as infection, malignancy and renal failure. Furthermore, recent evidence suggests that chronic immune-mediated injury to the liver may also impact graft function. PMID:27182155

Delayed gastric emptying is a significant postoperative complication of living donor hepatectomy for liver transplantation and may require endoscopic or surgical intervention in severe cases. Although the mechanism of posthepatectomy delayed gastric emptying remains unknown, vagal nerve injury during intraoperative dissection and adhesion formation postoperatively between the stomach and cut liver surface are possible explanations. Here, we present the first reported case of delayed gastric emptying following fully laparoscopic hepatectomy for living donor liver transplantation. Additionally, we also present a case in which symptoms developed after open right hepatectomy, but for which dissection for left hepatectomy was first performed. Through our experience and these two specific cases, we favor a neurovascular etiology for delayed gastric emptying after hepatectomy. PMID:25610698

Cytomegalovirus (CMV) is one of the most common viral pathogens causing clinical disease in liver transplant recipients, and contributing to substantial morbidity and occasional mortality. CMV causes febrile illness often accompanied by bone marrow suppression, and in some cases, invades tissues including the transplanted liver allograft. In addition, CMV has been significantly associated with an increased predisposition to acute and chronic allograft rejection, accelerated hepatitis C recurrence, and other opportunistic infections, as well as reduced overall patient and allograft survival. To negate the adverse effects of CMV infection on transplant outcome, its prevention, whether through antiviral prophylaxis or preemptive therapy, is an essential component to the management of liver transplant recipients. Two recently updated guidelines have suggested that antiviral prophylaxis or preemptive therapy are similarly effective in preventing CMV disease in modest-risk CMV-seropositive liver transplant recipients, while antiviral prophylaxis is the preferred strategy over preemptive therapy for the prevention of CMV disease in high-risk recipients [CMV-seronegative recipients of liver allografts from CMV-seropositive donors (D+/R-)]. However, antiviral prophylaxis has only delayed the onset of CMV disease in many CMV D+/R- liver transplant recipients, and such occurrence of late-onset CMV disease was significantly associated with increased all-cause and infection-related mortality after liver transplantation. Therefore, a search for better strategies for prevention, such as prolonged duration of antiviral prophylaxis, a hybrid approach (antiviral prophylaxis followed by preemptive therapy), or the use of immunologic measures to guide antiviral prophylaxis has been suggested to prevent late-onset CMV disease. The standard treatment of CMV disease consists of intravenous ganciclovir or oral valganciclovir, and if feasible, reduction in pharmacologic immunosuppression

Renal transplantation accounts for more than half of all solid organ transplants performed in the U.S., and the liver is the second most commonly transplanted solid organ. Although abdominal imaging procedures are commonplace in these patients, there has been relatively little attention paid to thoracic imaging applications. Preoperative imaging is crucial to aid in the exclusion of infectious or malignant disease. In the perioperative time period, thoracic imaging focuses both on standard intensive care unit care, including monitoring devices and their complications, and on the early infections that can occur. Postoperative management is divided into three time periods, and the principles governing the occurrence of infections and malignancies are reviewed. Anatomic and pathologic aspects unique to kidney and liver transplantation patients are also discussed.

In adult living donor liver transplantation (LDLT), maintenance of adequate portal inflow is essential for the graft regeneration. Portal inflow steal (PFS) may occur due to presence of huge spontaneous porto-systemic collaterals. A surgical procedure to increase the portal inflow is rarely necessary in adult LDLT. A 52 years male patient with end-stage liver disease due to chronic hepatitis C virus infection. Preoperative portography showed marked attenuated portal vein and its two main branches, patent tortuous splenic vein, multiple splenic hilar collaterals, and large lieno-renal collateral. He received a right hemi-liver graft from his nephew. Exploration revealed markedly cirrhotic liver, moderate splenomegaly with multiple collaterals and large lieno-renal collateral. Upon dissection of the hepato-duodenal ligament, a well-developed portal vein could be identified with a small mural thrombus. The recipient portal vein stump was anastomosed, in end to end fashion, to the graft portal vein. Doppler US showed reduced portal vein flow, so ligation of the huge lieno-renal collateral that allows steal of the portal inflow. After ligation of the lieno-renal collateral, improvement of the portal vein flow was observed in Doppler US. There is no accepted algorithm for managing spontaneous lieno-renal shunts before, during, or after liver transplantation, and evidence for efficacy of treatments remains limited. We report a case of surgical interruption of spontaneous huge porto-systemic collateral to prevent PFS during adult LDLT. Complete interruption of large collateral vessels might be needed as a part of adult LDLT procedure to avoid devastating postoperative PFS. Copyright © 2016. Published by Elsevier Ltd.

Sirolimus (SRL) is a new immunosuppressive drug approved for renal transplantation, but is being used increasingly in orthotopic liver transplantation (OLT). Compared with the calcineurin inhibitors, SRL has different mechanisms of action and side effects profile. Thus, this drug offers significant potential advantages over other immunosuppressive agents. SRL does not cause glucose intolerance, hypertension or renal failure, but it may cause dyslipidemia, hepatic artery thrombosis, thrombocytopenia, anemia, leukopenia, oral mucosa ulcers, edema, arthralgias and wound complications. SRL inhibits the signal of interleukin 2 at a post-receptor level, inhibiting lymphocyte proliferation and fibroblast proliferation. It also has antineoplastic and antifungal effects. We report a 10 years old girl who underwent OLT, experiencing a biopsy-proven recurrent acute rejection (AR) in spite of using three immunosuppressive agents (tacrolimus, mofetil micofenolate and steroids). She developed diabetes mellitus as a consequence of the immunosuppressive therapy. She was rescued with SRL, not experiencing AR again. Mofetil micofenolate, steroids and insulin could be discontinued and tacrolimus doses were reduced, without experiencing severe complications. SRL is a new and safe immunosuppressive agent for rescue in patients with OLT and recurrent AR.

Hepatology and Liver Transplantation Unit,Hôtel-Dieu Croix-Rousse,Lyon,France D MUTIMER Cirrhosis due to hepatitis C virus (HCV) is now the most common indication of liver transplantation in Western Europe and the United States. In the absence of effective prophylaxis, recurrent HCV infection is almost inevitable. Though the natural history and intermediate term outcome of recurrent HCV are now better documented, those factors which may influence the recurrence of hepatitis and consequent progression of graft disease remain unclear. Interferon (IFN) as a sole agent for the treatment of recurrent infection has proved unsatisfactory. Early intervention with a combination of IFN and ribavirin seems promising, and this approach may prevent or delay progression of HCV related graft disease after liver transplantation. PMID:10075968

Anatomic variations of the portal vein (PV) and bile duct (BD) are more common on the right lobe as compared with left lobe grafts in living donor liver transplantation (LDLT). We recently experienced a case of LDLT for hepatocellular carcinoma combined with liver cirrhosis secondary to hepatitis B virus and hepatitis C virus infection. The only available donor had right lobe graft with type IV PV associated with type IV BD. The patient underwent relaparotomy for PV stenting due to PV stenosis. Percutaneous transhepatic biliary drainage was done for a stricture at the site of biliary reconstruction. Thereafter, the patient was discharged in good health. Our experience suggests that, the use of right lobe graft with type IV PV accompanied by type IV BD should be the last choice for LDLT, because of its technical difficulty and risks of associated complications.

Paracoccidioidomycosis is a granulomatous systemic mycosis that is endemic in Latin America; it is an extremely rare infection following solid organ transplantation. In this study, we describe the first report of disseminated paracoccidioidomycosis in a 3-year-old girl who underwent liver transplantation 2 years previously. The radiologic diagnosis and patient follow-up are described. In addition, we review the clinical evolution and treatment regimens for this infection.

We report a fatal case of disseminated Emmonsia sp. infection in a 55-year-old man who received an orthotopic liver transplant. The patient had pneumonia and fungemia, and multisystem organ failure developed. As human habitats and the number of immunocompromised patients increase, physicians must be aware of this emerging fungal infection. PMID:28098544

Describe the results of liver transplantation after installing Transjugular Intrahepatic Portosystemic Shunt (TIPS) and compare them with those of a control group in a comparative, longitudinal, retrospective study. Between April 1986 and October 2002, we performed 875 liver transplantations. Between January 1996 and October 2002, 26 transplantations were performed on TIPS carriers. This group was compared with a control cohort of 50 randomly selected patients who underwent transplantation in this period (non-TIPS carriers). Both groups were homogeneous with no significant differences between age, sex United Network for Organ Sharing (UNOS) score, Child stage, or etiology. Actuarial survival rates at 1 and 3 years: TIPS group 96.15% and 89.29% versus control cohort 87.8% and 81%, respectively. In 73.9%, the TIPS was clearly effective; in 88.9%, a postoperative Doppler revealed normal flow. There were no statistically significant differences compared with time on the waiting list for transplant, duration of the operation, ischemia times, intraoperative consumption of hemoderivates, vascular or nonvascular postoperative complications, duration of stay in the intensive care unit, hospital stay, or retransplantation rate. In our experience, TIPS insertion does not affect either the intraoperative or postoperative evolution and is not associated with an increased time on the liver transplant waiting list.

Concern exists that liver transplant center substance abuse policies may have an inappropriate and disproportionate impact on marijuana users. Our hypothesis is that patients with chronic liver disease who were marijuana users will have inferior survival. This is a retrospective (1999-2007) cohort study. The primary outcome measure is time-dependent, adjusted patient survival from the time of liver transplant evaluation. The primary exposure variable is a positive cannabinoid toxicology screen during the liver transplant evaluation period. Overall, 155 patients qualified as marijuana users while 1334 patients were marijuana non-users. Marijuana users were significantly (p < 0.05) younger (48.3 vs. 52.1), more likely to be male (78.1% vs. 63.0%), have hepatitis C (63.9% vs. 40.6%) and were less likely to receive a transplant (21.8% vs. 14.8%). Marijuana users were more likely to use tobacco, narcotics, benzodiazepines, amphetamines, cocaine or barbiturates (p < 0.05). Unadjusted survival rates were similar between cohorts. Upon multivariate analysis, MELD score, hepatitis C and transplantation were significantly associated with survival, while marijuana use was not (HR 1.09, 95% CI 0.78-1.54). We conclude that patients who did and did not use marijuana had similar survival rates. Current substance abuse policies do not seen to systematically expose marijuana users to additional risk of mortality.

Mortality rates on the liver transplant waiting list are increasing. The shortage of organs has resulted in higher utilization of extended criteria donors (ECDs), with centers pushing the limits of what is acceptable for transplantation. Donor quality is more appropriately represented as a continuum of risk, and careful selection and matching of ECD grafts with recipients may lead to excellent outcomes. Although there is no precise definition for what constitutes an ECD liver, this review focuses on frequently cited characteristics, including donor age, steatosis, donation after cardiac death, and donors with increased risk of disease transmission.

Living donor liver transplantation (LDLT) has gone through its formative years and established as a legitimate treatment when a deceased donor liver graft is not timely or simply not available at all. Nevertheless, LDLT is characterized by its technical complexity and ethical controversy. These are the consequences of a single organ having to serve two subjects, the donor and the recipient, instantaneously. The transplant community has a common ground on assuring donor safety while achieving predictable recipient success. With this background, a reflection of the development of LDLT may be appropriate to direct future research and patient-care efforts on this life-saving treatment alternative. PMID:18176956

Due to the shortage of cadaver liver grafts in Asia, more than 90% of biliary atresia (BA) patients require living donor liver transplantation (LDLT), but the factors that influence liver graft regeneration in pediatric patients are still unclear. The aim of this study was to evaluate the potential predisposing factors that encourage liver graft regeneration in pediatric liver transplantation (LT). Case notes and Doppler ultrasound and computed tomography studies performed before and 6 months after transplantation of 103 BA patients who underwent LDLT were reviewed. The predisposing factors that triggered liver regeneration were compiled from statistical analyses and included the following: age, gender, body weight and height, spleen size, graft weight-to-recipient weight ratio (GRWR), post-transplantation total portal flow, and vascular complications. Seventy-two pediatric recipients were enrolled in this study. The liver graft regeneration rate was 29.633 ± 36.61% (range, -29.53-126.27%). The size of the spleen (P = .001), post-transplantation portal flow (P = .004), and age (P = .04) were correlated lineally with the regeneration rate. The GRWR was negatively correlated with the regeneration rate (P = .001) and was the only independent factor that affected the regeneration rate. When the GRWR was >3.4, patients tended to have poor and negative graft regeneration (P = .01). Large-for-size grafts have negative effect on regeneration rates because liver grafts that are too large can compromise total portal flow and increase vascular complications, especially when the GRWR is >3.4. Thus, optimal graft size is more essential than other factors in a pediatric LDLT patient. Crown Copyright © 2014. Published by Elsevier Inc. All rights reserved.

We report a 40-year-old man with end-stage renal disease due to IgA nephropathy who underwent deceased donor kidney transplantation. The donor was diagnosed to be brain-dead due to cerebral hemorrhage after her second liver transplantation for non-viral liver cirrhosis. Intraoperative 1-hour biopsy of the graft kidney revealed moderate global glomerular sclerosis (22%) and interstitial fibrosis (40%) consistent with underlying nephrosclerosis or calcineurin inhibitor nephrotoxicity. Although hemodialysis was needed until the graft began functioning several days after the kidney transplantation, the postoperative clinical course thereafter was uneventful and the graft functioned well with stable serum creatinine levels around 2.4 mg/dl at 6 monthspos toperatively.

The use of herbal medications is increasing significantly in the UK and there is a perception that herbal preparations are without adverse effects. This case report highlights the potential risks of black cohosh, which is one of the most commonly used herbal products. This is a case report of a 60-year-old Caucasian lady who presented with subacute liver failure secondary to taking black cohosh. This was further confirmed by liver biopsy and she subsequently deteriorated and underwent liver transplantation. Available evidence supports an association between black cohosh and risk of hepatotoxicity. In current literature, there have only been four previously reported cases of hepatotoxicity associated with black cohosh, which required liver transplantation. We submit that our patient represents the fifth case. We recommend that patients taking this supplement should have close monitoring of their hepatic function, especially in the presence of other risk factors. PMID:23833086

Hepatitis C virus (HCV) infection has been linked with some extrahepatic immunologic abnormalities. Cryoglobulinemia is one of the most frequently reported. Nevertheless, there are only a few reports of cryoglobulinemia in the setting of liver transplantation. More studies are needed to clarify the frequency of post-OLT cryoglobulinemia in patients with HCV-related cirrhosis and its impact on OLT outcome. A case of a patient who underwent liver transplantation because of HCV end-stage liver disease and in whom cryoglobulinemia appeared 3 years after transplantation is reported. Treatment with cyclophosphamide and steroids was attempted but patient died of septicemia 3 years after liver transplantation.

Liver-kidney transplantation is a rare procedure in children, with just ten to 30 cases performed annually worldwide. The main indications are autosomal recessive polycystic liver-kidney disease and primary hyperoxaluria. This study aimed to report outcomes of liver-kidney transplantation in a cohort of pediatric patients. We retrospectively analyzed all pediatric liver-kidney transplantations performed in our center between September 2000 and August 2015. Patient data were obtained by reviewing inpatient and outpatient medical records and our transplant database. A total of 14 liver-kidney transplants were performed during the study period, with a median patient age and weight at transplant of 144.4 months (131.0-147.7) and 27.3 kg (12.0-45.1), respectively. The indications for liver-kidney transplants were autosomal recessive polycystic liver-kidney disease (8/14), primary hyperoxaluria -1 (5/14), and idiopathic portal hypertension with end-stage renal disease (1/14). Median time on waiting list was 8.5 months (5.7-17.3). All but two liver-kidney transplants were performed simultaneously. Patients with primary hyperoxaluria-1 tended to present a delayed recovery of renal function compared with patients transplanted for other indications (62.5 vs 6.5 days, respectively, P 0.076). Patients with liver-kidney transplants tended to present a lower risk of acute kidney rejection than patients transplanted with an isolated kidney transplant (7.2% vs 32.7%, respectively; P < 0.07). Patient and graft survival at 1, 3, and 5 years were 100%, 91.7%, 91.7%, and 91.7%, 83.3%, 83.3%, respectively. No other grafts were lost. Long-term results of liver-kidney transplants in children are encouraging, being comparable with those obtained in isolated liver transplantation.

Background As an important means to tackle the worldwide shortage of liver grafts, adult-adult living donor liver transplantation (A-ALDLT) is the most massive operation a healthy person could undergo, so donor safety is of prime importance. However, most previous research focused on recipients, while complications in donors have not been fully described or investigated. Material/Methods To investigate donor safety in terms of postoperative complications, the clinical data of 356 A-ALDLT donors in our center from January 2002 to September 2015 were retrospectively analyzed. These patients were divided into a pre-2008 group (before January 2008) and a post-2008 group (after January 2008). Donor safety was evaluated with regard to the type, frequency, and severity of postoperative complications. Results There were no donor deaths in our center during this period. The overall complication rate was 23.0% (82/356). The proportion of Clavien I, II, III, and IV complications was 51.2% (42/82), 25.6% (21/82), 22.0% (18/82), and 1.2% (1/82), respectively. In all the donors, the incidence of Clavien I, II, III, and IV complications was 11.8% (42/356), 5.9% (21/356), 5.1% (18/356), and 0.3% (1/356), respectively. The overall complication rate in the post-2008 group was significantly lower than that in the pre-2008 group (18.1% (41/227) vs. 32.6% (42/129), P<0.01). Biliary complications were the most common, with an incidence of 8.4% (30/356). Conclusions The risk to A-ALDLT donors is controllable and acceptable with improvement in preoperative assessment and liver surgery. PMID:27178367

Glycogen storage disease Ib is a rare, inherited metabolic disorder caused by glucose-6-phosphatase translocase deficiency. Its main symptoms are hypoglycemia, hyperlipidemia, neutropenia, hepatomegaly, liver adenomas and short stature. The exact mechanism of short stature in this disease is unclear, the most feasible possibility is that it is caused by impairment of growth-hormone and insulin-like growth factor I axis. Here we report the case of a patient who showed typical symptoms of glycogen storage disease Ib since his infancy, his height being under 1 percentile since then. Later-developed hypothyroidism and hypogonadism have also contributed to his short stature. Hypothyroidism was treated but sexual steroid substitution was not started because of an increased risk of hepatic adenomas. Because he developed hepatic adenoma at the age of 23, he had to undergo orthotopic liver transplantation. At the time of the transplantation his height was 128cm. The transplantation was followed by rapid height growth; our patient's height reached 160.3cm 62months after transplantation. We observed that while his IGF-I level increased, his GH level remained unchanged. During the post-transplantation period we ensured adequate calcium and vitamin D supplementation, leaving hormonal substitution unchanged. According to our knowledge, this is the first report of a rapid height growth as big as 32cm, of an individual over the age of 20, not related to endocrine treatment but liver transplantation.

The decision for isolated kidney transplant (KT) vs. combined liver-kidney transplant (CLKT) in patients with end-stage renal disease (ESRD) with compensated cirrhosis remains controversial. We sought to determine outcomes of patients requiring listing for a liver transplant (LT) following either a cadaveric or living donor KT and compare these outcomes to similar patients receiving a CLKT. Our dataset included the United Network for Organ Sharing (UNOS)/Standard Transplant and Analysis and Research (STAR) kidney files from 1987 to 2012 after being joined with the liver files from 2002 to 2012. Outcomes of patients who received a CLKT with an international normalized ratio (INR) ≤1 and total bilirubin ≤1 were compared to patients who received a primary KT and subsequently required listing for LT between zero and five yr or after five yr. For the three groups, 244 patients had a CLKT, 216 were wait-listed for LT between zero and five yr after KT (0-5 WL), and 320 were wait-listed five yr after KT (+5 WL). From the time of KT, the 0-5 WL group had significantly worse survival than the CLKT group and the +5 WL group. The +5 WL had the best survival of all groups. For the 0-5 WL group, 45% underwent LT and 40% died while waiting compared to the +5 WL group with 53% having LT and 26% died while waiting. At the time of LT, the 0-5 WL group had a higher model for end-stage liver disease (MELD) score, higher incidence of being in the ICU at the time of transplant, and higher incidence of requiring life support. From the time of LT, the CLKT trended toward better survival (p = 0.0549) than both the 0-5 WL and +5 WL groups, which had equivalent survival. The 0-5 WL group is a higher risk group with poorer survival due to a higher incidence of dying on the waitlist. Better identification of patients with a high risk for hepatic decompensation following KT and agreement for regional exception for LT in the event of decompensation may improve utilization of organs and

Histology is the gold standard for diagnosing acute rejection and hepatitis C recurrence after liver transplantation. However, differential diagnosis between the two can be difficult. We evaluated the role of C4d staining and quantification of hepatitis C virus (HCV) RNA levels in liver tissue. This was a retrospective study of 98 liver biopsy samples divided into four groups by histological diagnosis: acute rejection in patients undergoing liver transplant for hepatitis C (RejHCV+), HCV recurrence in patients undergoing liver transplant for hepatitis C (HCVTx+), acute rejection in patients undergoing liver transplant for reasons other than hepatitis C and chronic hepatitis C not transplanted (HCVTx-). All samples were submitted for immunohistochemical staining for C4d and HCV RNA quantification. Immunoexpression of C4d was observed in the portal vessels and was highest in the HCVTx- group. There was no difference in C4d expression between the RejHCV+ and HCVTx+ groups. However, tissue HCV RNA levels were higher in the HCVTx+ group samples than in the RejHCV+ group samples. Additionally, there was a significant correlation between tissue and serum levels of HCV RNA. The quantification of HCV RNA in liver tissue might prove to be an efficient diagnostic test for the recurrence of HCV infection. PMID:25742264

Recent changes in Center for Medicare & Medicaid Services (CMS) condition for participation, using benchmark volume/outcomes requirements for certification, have been implemented. Consequently, the ability of a transplant center to assess its risk tolerance is important in successful management. An analysis of SRTR data was performed to determine donor/recipient risk factors for graft loss or patient death in the first year. Each transplant performed was then assigned a prospective relative risk (RR) of failure. Using a Monte-Carlo simulation, transplants were selected at random that met the centers' acceptable risk tolerance. Transplant center volume was fixed and its risk tolerance was adjusted to determine the impact on outcomes. The model was run 1000 times on centers with varying volume. The modeling demonstrates that centers with smaller annual volumes must use a more risk taking strategy than larger volume centers to avoid being flagged for CMS volume requirements. The modeling also demonstrates optimal risk taking strategies for centers based upon volume to minimize the probability of being flagged for not meeting volume or outcomes benchmarks. Small volume centers must perform higher risk transplants to meet current CMS requirements and are at risk for adverse action secondary to chance alone.

Living donor liver transplantation (LDLT) has been increasingly embraced around the world as an important strategy to address the shortage of deceased donor livers. The aim of this guideline, approved by the International Liver Transplantation Society (ILTS), is to provide a collection of expert opinions, consensus, and best practices surrounding LDLT. Recommendations were developed from an analysis of the National Library of Medicine living donor transplantation indexed literature using the Grading of Recommendations Assessment, Development and Evaluation methodology. Writing was guided by the ILTS Policy on the Development and Use of Practice Guidelines (www.ilts.org). Intended for use by physicians, these recommendations support specific approaches to the diagnostic, therapeutic, and preventive aspects of care of living donor liver transplant recipients.

As the liver transplant journey in India reaches substantial numbers and suggests quality technical expertise, it is time to dispassionately look at the big picture, identify problems, and consider corrective measures for the future. Several features characterize the current scenario. Although the proportion of deceased donor liver transplants is increasing, besides major regional imbalances, the activity is heavily loaded in favor of the private sector and live donor transplants. The high costs of the procedure, the poor participation of public hospitals, the lack of a national registry, and outcomes reporting are issues of concern. Organ sharing protocols currently based on chronology or institutional rotation need to move to a more justiciable severity-based system. Several measures can expand the deceased donor pool. The safety of the living donor continues to need close scrutiny and focus. Multiple medical challenges unique to the Indian situation are also being thrown up. Although many of the deficits demand state intervention and policy changes the transplant community needs to take notice and highlight them. The future of liver transplantation in India should move toward a more accountable, equitable, and accessible form. We owe this to our citizens who have shown tremendous faith in us by volunteering to be living donors as well as consenting for deceased donation. PMID:26900275

The purpose of this case report is to describe a patient with a preoperative complex pain syndrome who underwent liver transplantation and was able to reduce his opioid consumption significantly following the initiation of treatment with medical cannabis. A 57-yr-old male with a history of hepatitis C cirrhosis underwent liver transplantation. Preoperatively, he was taking hydromorphone 2-8 mg⋅day(-1) for chronic abdominal pain. Postoperatively, he was given intravenous patient-controlled analgesia through which he received hydromorphone 30 mg⋅day(-1). Our multidisciplinary Transitional Pain Service was involved with managing his moderate to severe acute postsurgical pain in hospital and continued with weaning him from opioid medications after discharge. It was difficult to wean the patient from opioids, and he was subsequently given medical cannabis at six weeks postoperatively with remarkable effect. By the fifth postoperative month, his use of opioids had tapered to 6 mg⋅day(-1) of hydromorphone, and his functional status was excellent on this regimen. Reductions in opioid consumption were achieved with the administration of medical cannabis in a patient with acute postoperative pain superimposed on a chronic pain syndrome and receiving high doses of opioids. Concurrent benefits of initiating medical cannabis may include improvements in pain profile and functional status along with reductions in opioid-related side effects. This highlights the potential for medical cannabis as an adjunct medication for weaning patients from opioid use.

Liver transplantation is the only live-saving, curative treatment for various end-stage liver diseases, and it has excellent survival rates. Mycophenolate mofetil is widely used as co-medication for immunosuppression after liver transplantation, especially to allow a sparing effect on calcineurin-inhibitors, thus reducing their numerous adverse effects. It improves both graft and patient survival. The properties of its active metabolite, mycophenolic acid, are diverse: inhibition of de novo purine synthesis and selective lymphocyte inhibition, anti-tumoral, antiviral, anti-angioneoplastic, and vasculoprotective mechanisms are described and summarized in this review. The most common adverse effects of mycophenolate mofetil are gastrointestinal complaints such as diarrhea, which often lead to dose-reduction or withdrawal of mycophenolate mofetil. A newer, enteric-coated formulation is available, which is meant to reduce the gastrointestinal adverse effects. Mycophenolate mofetil does not relevantly interact with other common drugs. The question of whether therapeutic drug monitoring allows optimized dosing strategies cannot be satisfyingly answered yet. The optimal partner-immunosuppressant seems to be tacrolimus, especially in low doses. This tutorial review provides an overview of recent studies exploring the role of mycophenolate mofetil in liver transplantation with regards to its development, mechanism of action, and actual controversies such as therapeutic drug monitoring or de novo malignancy after transplantation.

The metabolic syndrome (MS), which includes obesity, dyslipidaemia, hypertension and hyperglycaemia according to the most widely accepted definitions now used, is one of the most common post-transplant complications, with a prevalence of 44%-58%. The MS, together with the immunosuppression, is considered the main risk factor for the development of cardiovascular disease (CVD) in transplant recipients, which in turn accounts for 19%-42% of all deaths unrelated to the graft. The presence of MS represents a relative risk for the development of CVD and death of 1.78. On the other hand, non-alcoholic fatty liver disease (NAFLD), considered as the manifestation of the MS in the liver, is now the second leading reason for liver transplantation in the United States after hepatitis C and alcohol. NAFLD has a high rate of recurrence in the liver graft and a direct relation with the worsening of other metabolic disorders, such as insulin resistance or diabetes mellitus. Consequently, it is vitally important to identify and treat as soon as possible such modifiable factors as hypertension, overweight, hyperlipidaemia or diabetes in transplanted patients to thus minimise the impact on patient survival. Additionally, steroid-free regimens are favoured, with minimal immunosuppression to limit the possible effects on the development of the MS. PMID:27605877

To assess clinical safety of a low central venous pressure (CVP) fluid management strategy in patients undergoing liver transplantation. Retrospective record review comparing 2 transplant centers, one using the low CVP method and the other using the normal CVP method. University-based, academic, tertiary care centers. Patients undergoing orthotopic cadaveric liver transplantation. Each center practiced according to its own standard of care. Center 1 maintained an intraoperative CVP <5 mmHg using fluid restriction, nitroglycerin, forced diuresis, and morphine. If pressors were required to maintain systolic arterial pressure >90 mmHg, phenylephrine or norepinephrine was used. At center 2, CVP was kept 7 to 10 mmHg and mean arterial pressure >75 mmHg with minimal use of vasoactive drugs. Data collected included United Network for Organ Sharing status, surgical technique, intraoperative transfusion rate, preoperative and peak postoperative creatinine, time spent in intensive care unit and hospital, incidence of death, and postoperative need for hemodialysis. Principal findings include an increased rate of transfusion in the normal CVP group but increased rates of postoperative renal failure (elevated creatinine and more frequent need for dialysis) and 30-day mortality in the low CVP group. Despite success in lowering blood transfusion requirements in liver resection patients, a low CVP should be avoided in patients undergoing liver transplantation.

Physicians previously thought that heart disease was rare in patients with end stage liver disease. However, recent evidence shows that the prevalence of ischemic heart disease and cardiomyopathy is increased in transplant candidates compared to most other surgical candidates. Investigators estimate that up to 26% of all liver transplant candidates have at least one critical coronary artery stenosis and that at least half of these patients will die perioperatively of cardiac complications. Cardiomyopathy also occurs in greater frequency. While all patients with advanced cardiac disease have defects in cardiac performance, a larger than expected number of patients have classical findings of dilated, restrictive and hypertrophic cardiomyopathy. This may explain why up to 56% of patients suffer from hypoxemia due to pulmonary edema following transplant surgery. There is considerable controversy on how to screen transplant candidates for the presence of heart disease. Questions focus upon, which patients should be screened and what tests should be used. This review examines screening strategies for transplant candidates and details the prognostic value of common tests used to identify ischemic heart disease. We also review the physiological consequences of cardiomyopathy in transplant candidates and explore the specific syndrome of “cirrhotic cardiomyopathy”. PMID:18567069

Since 1963, when the first human liver transplantation (LT) was performed by Thomas Starzl, the world has witnessed 50 years of development in surgical techniques, immunosuppression, organ allocation, donor selection, and the indications and contraindications for LT. This has led to the mainstream, well-established procedure that has saved innumerable lives worldwide. Today, there are hundreds of liver transplant centres in over 80 countries. This review aims to describe the main aspects of LT regarding the progressive changes that have occurred over the years. We herein review historical aspects since the first experimental studies and the first attempts at human transplantation. We also provide an overview of immunosuppressive agents and their potential side effects, the evolution of the indications and contraindications of LT, the evolution of survival according to different time periods, and the evolution of methods of organ allocation.

The linear growth of 29 patients was evaluated from two to 4⅓ years after liver transplantation. All patients received cyclosporine and low-dose prednisone, light patients (28%) displayed acceleration of linear growth velocity and were above the fifth percentile at the end of the evaluation period. Four patients (14%) grew normally prior to transplantation and continued to grow normally after the surgical procedure. Only four patients (14%) dropped from higher levels to below the fifth percentile. Thirteen patients (45%) were less than the fifth percentile before and after surgery; ten of these 13 patients have attained normal or accelerated growth velocity. Good linear growth has been achieved in more than three fourths of patients who underwent liver transplantation. PMID:3554981

Portal hypertension induces congestion of the liver and spleen, thus any capsular or parenchymal injury to these organs can produce intractable bleeding which generally is not easily controlled. To cope with intractable bleeding such as being encountered during liver transplantation, we developed an infiltrating hemostasis technique as a conceptual shift from conventional application methods, in which fibrin glue is locally injected into the bleeding area on the liver or spleen. This technique, which uses a fibrin glue kit (2 ml kit; Greenplast, Green Cross, Seoul, Korea), consists of inserting the needle 0.5-1 cm deep at the bleeding point, forcefully injecting 1 ml of fibrin glue contained in the fibrin glue kit, and then slowly withdrawing the needle with continuous forceful injection of the remaining 1 ml of fibrin glue. We have successfully performed this procedure in 6 cases of living donor liver transplantation and in 2 cases of non-transplant resection of the cirrhotic livers with hepatocellular carcinoma. This technique was also successfully applied to one liver transplant recipient in which intractable bleeding occurred from a small laceration at the spleen. Our fibrin glue-infiltrating hemostasis would be indicated to intractable bleeding from the hepatic or splenic cut surface. In such a situation, it would be applicable as a second-line rescue method for hemostasis. PMID:28261700

Background De novo malignancies occur after liver transplantation because of immunosuppression and improved long-term survival. But the spectrums and associated risk factors remain unclear. Aims To describe the overall pattern of de novo cancers in liver transplant recipients. Methods Data from Scientific Registry of Transplant Recipients from October 1987 to December 2009 were analyzed. The spectrum of de novo cancer was analyzed and logistic-regression was used to identify predictors of do novo malignancies. Results Among 89,036 liver transplant recipients, 6,834 recipients developed 9,717 post-transplant malignancies. We focused on non-skin malignancies. A total of 3,845 recipients suffered from 4,854 de novo non-skin malignancies, including 1,098 de novo hematological malignancies, 38 donor-related cases, and 3,718 de novo solid-organ malignancies. Liver transplant recipients had more than 11 times elevated cancer risk compared with the general population. The long-term overall survival was better for recipients without de novo cancer. Multivariate analysis indicated that HCV, alcoholic liver disease, autoimmune liver disease, nonalcoholic steatohepatitis, re-transplantation, combined transplantation, hepatocellular carcinoma, immunosuppression regime of cellcept, cyclosporine, sirolimus, steroids and tacrolimus were independent predictors for the development of solid malignancies after liver transplantation. Conclusions De novo cancer risk was elevated in liver transplant recipients. Multiple factors including age, gender, underlying liver disease and immunosuppression were associated with the development of de novo cancer. This is useful in guiding recipient selection as well as post-transplant surveillance and prevention. PMID:27171501

Background The current organ shortage has prompted the use of marginal organs. We conducted this retrospective study to present our experience with transplanting deceased donor livers with elevated levels of serum transaminases and to explain whether elevated levels of serum transaminases in donors affect allograft function and survival of the recipients. Methods Data of deceased donor livers and patients, who underwent liver transplantation from March 2013 to March 2015 at Shiraz center for organ transplantation, was reviewed. Liver donors with aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) level of more than 500 IU/l and their related recipients were considered as the case group (n = 24) and the others were considered as the control group (n = 834). Results In the case group, the medians of levels of serum AST and ALT of donors were 834 ± 425 IU/L (range: 250 - 2285) and 507 ± 367 IU/L (range: 100 - 1600), respectively. Recipients were followed for a median of 13.6 ± 9 months (range: 7 - 28.4). Post-transplant complications were acute rejection (n = 5), infection (n = 3), portal vein thrombosis (n = 3), bile duct stricture (n = 1), and hepatic artery stenosis (n = 1). The one-year survival rate of the patients was 91.7%. Demographics, post-transplant complications and one-year survival rates were not significantly different between the two study groups. Conclusions Transplanting deceased donor livers with markedly elevated liver enzymes may be an acceptable choice for expanding the donor pool. PMID:27882068

The authors reviewed the prevalence of postoperative infections, the results of bacterium cultures, and the incidence of multidrug resistance in their liver transplanted patients during a period between 2003 and 2012. The aim of this study was to analyse risk factors and colonisations of bacterial infections. The files of 408 patients (281 bacterium cultures) were reviewed. Of the 408 patients 70 had a postoperative infection (17%); 58 patients (14.2%) had positive and 12 patients (2.9%) negative bacterial culture results. Cholangitis was found in 7 cases (12.1%), abdominal infection in 17 cases (29.3%), and pulmonary infection in 28 cases (48.3%). Postoperative infection was more frequent in patients with initial poor graft function, acute renal insufficiency, biliary complication, and in those with intraabdominal bleeding. The 1-, 3- and 5-year cumulative survival of patients who had infection was 70%, 56% and 56%, respectively, whereas the cumulative survival data of patients without infection was 94%, 87% and 85%, respectively (p<0.001). Multidrug resistance was found in 56% of the positive cultures, however, the one-year survival was not different in patients who had multidrug resistance positive and negative bacterial infection (both 70.2%). Infection control must target the management of multidrug resistance microbes through encouraging prevention, hygienic, and isolation rules, improving the operative, transfusion, and antimicrobial policy in a teamwork setting.

BACKGROUND Kaposi sarcoma (KS) is the most frequent skin cancer in solid organ recipients, and also a typical malignancy in HIV-infected persons. CASE REPORT We describe here a rare case of primary nodal KS without mucocutaneous manifestations, diagnosed in a 20-year-old HIV/HBV co-infected patient 12 months after liver transplantation (LT), the first one performed in a HIV-positive patient in Poland. The course of the disease was very aggressive; the patient died four weeks after general lymphadenopathy appearance. In the autopsy, KS infiltration was found in numerous lymph nodes and in the lung' apexes without skin or other organs' involvement. CONCLUSIONS In conclusion, posttransplant KS may present as general lymphadenopathy without mucocutaneous manifestations, thus mimicking posttransplant lymphoproliferative disorder, which is often the first clinical suspicion. Lymph node histopathological examination is necessary to make the right diagnosis.

Various techniques of flushing and reperfusion have been advocated to improve outcomes after liver transplantation. There is considerable uncertainty as to which method is superior. To compare the benefits and harms of different methods of flushing and reperfusion during liver implantation in the transplant recipients. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until March 2011. We included all randomised clinical trials that were performed to compare different techniques of flushing and reperfusion during liver transplantation. Two authors independently identified the trials and extracted the data. We analysed the data with both the fixed-effect model and the random-effects model using RevMan analysis. For each outcome we calculated the hazard ratio (HR), risk ratio (RR), rate ratio, mean difference (MD), or standardised mean difference (SMD) with 95% confidence intervals (CI) based on available case analysis. We included six trials involving 418 patients for this review. The sample size in the trials varied from 30 to 131 patients. Only one trial involving 131 patients was of low risk of bias for mortality. This trial was at high risk of bias for other outcomes. Four trials excluded patients who underwent liver transplantation for acute liver failure. All the trials included livers obtained from cadaveric donors. The remaining five trials were of high risk of bias for all outcomes. Liver transplantation was performed by the conventional method (caval replacement) in two trials and piggy-back method (caval preservation) in one trial. The method of liver transplantation was not available in the remaining three trials. The comparisons performed included an initial hepatic artery flush versus initial portal vein flush; blood venting via inferior vena cava in addition to venting of storage fluid versus no blood venting; initial hepatic artery reperfusion versus

Proteinuria is a manifestation of renal dysfunction and it has been demonstrated to be a significant prognostic factor in various clinical situations. The study was designed to analyze prognosis of patients receiving liver transplantation as well as to determine predictive performance of perioperative proteinuria. We retrospectively reviewed data of patients who had received a liver transplant in a medical center between 2002 and 2010. Demographic information and clinical characteristic parameters were recorded on the day of intensive care unit admission before operation and on postoperative days 1, 7, and 14. Among a total of 323 patients, in-hospital mortality and 90-day mortality rates were 13.0 % (42/323) and 14.2 % (46/323), respectively. Patients with proteinuria on admission had higher rates of acute kidney injury (26.8 % vs. 8.8 %, p < 0.001), severe infection episodes (48.8 % vs. 30.7 %, p = 0.023), hospital death (31.1 % vs. 10.1 %, p < 0.001), and 90-day mortality (37.7 % vs. 10.9 %, p < 0.001). Multivariate analysis showed that proteinuria on admission and Sequential Organ Failure Assessment (SOFA) score were independent predictors of in-hospital mortality. The discriminatory ability of proteinuria plus SOFA was even better than that of SOFA alone, especially on postoperative day 1. The presence of proteinuria before liver transplantation is supposed to be recognized as a negative predictor for in-hospital survival. Moreover, the presence of proteinuria after liver transplantation can assist in the early prediction of poor short-term prognosis for patients receiving liver transplantation.
The liver transplant program at the transplant center of Tianjin First Center Hospital opened in 1994 and has become a leading center for academic research and development in clinical liver transplantation during the past 18 years. As of Nov 30, 2011, we had performed 4,103 liver transplantations in patients ranging from 6 months to 79 years old. Since 1998, the program has ranked first in mainland China in the annual number of liver transplants performed, the cumulative total liver transplants and the number of long-surviving patients. We've accomplished a number of "firsts" among the Chinese liver transplant centers, including: the first split liver transplantation, the first pediatric liver transplant, the first living donor simultaneous liver-kidney transplant, the first dual-graft liver transplant using a domino right lobe and a living donor left lobe, the first laparoscopic assisted live donor right hepatectomy including the middle hepatic vein and we have assembled the first liver transplant chain comprising multiple donors and recipients. We have performed the largest number of living related and split liver transplantations in mainland China. The combined prophylactic protocol of "Lamivudine and HBIG" to prevent HBV recurrence post transplantation was first used by our center in China and now is utilized by most of the domestic transplant centers. We have begun using livers from donors after cardiac death (DCD) during the past 2 years, with careful donor selection and recipient management. All the approaches and techniques we've developed are aimed at the utilization of all types of available grafts. However, increasing the rate of transplantation with excellent graft and recipient survival are still the challenges facing us.

Over the last decade, liver transplantation has become an operational reality in our part of the world. As a result, clinicians working in an intensive care unit are more likely to be exposed to these patients in the immediate postoperative period, and thus, it is important that they have a working knowledge of the common complications, when they are likely to occur, and how to deal with them. The main focus of this review is to address the variety of critical care issues in liver transplant recipients and to impress upon the need to provide favorable circumstances for the new liver to start functioning and maintain the function of other organs to aid in this process.

Three pediatric patients with hypertension occurring early after liver transplantation are reviewed. The patients were all female, and underwent living donor liver transplantation at the age of 9 years, 1 month, and 7 months. The etiology of liver disease was cirrhosis due to biliary atresia in two patients and fulminant hepatitis in one patient. Antihypertensive therapy with calcium channel blocker alone was not effective. Blood pressure was eventually controlled after the administration of a beta-adrenergic blocker in addition to the calcium channel blocker to all patients. No end-organ damage was observed, except that two patients developed temporary left ventricular hypertrophy.

A 60-years-old (85 kg, 178 cm) coronary arterial disease patient having had acute myocardial infarction for several times received liver transplantation successfully. He had a previous episode of acute myocardial infarction associated with entire obstruction of right coronary 6 years ago, and was inserted a bracket then. One year ago the patient got chest pain again, and was diagnosed as inferior wall myocardial infarction. Then he received expectant treatment in internal medical department for several days. A 774HF75 PAC catheter (Edwards Lifescience, USA) was inserted into an internal jugular vein, and cardiac output, right ventricular end diastolic volume index, right ventricular ejection fraction, stroke volume index, system vascular resistance, pulmonary vascular resistance, left ventricular-stroke work index and right ventricular-stroke work index were calculated. During the operation, cardiovascular medications such as dopamine, norepinephrine, dobutamine were infused and adjusted by steps carefully. Electrolytes and acid-base balance were maintained normal. With these hemodynamic parameters, BGA and systemic management, the anesthesia was managed safely and successfully.

Liver transplant recipients frequently suffer gastrointestinal (GI) complications but their prevalence and their influence on quality of life remain unknown. The objective of this study was to asses the prevalence, impact on quality of life, and management of GI complications in liver transplant recipients. This was an epidemiologic, cross-sectional, multicenter study. Four hundred seventeen liver recipients were recruited in 14 centers. A questionnaire was filled for every patient. The median age of the patients was 55 years. The median time since transplantation was 4.1 +/- 4 years. Whereas 19.2% presented some GI disease before transplantation, 49.4% showed this type of complication after transplantation. Diarrhea was the most prevalent GI complication, and anorexia was the GI disorder that affected patients daily activities the most frequently. GI complications were more frequent among female patients, subjects with pretransplantation hiatal hernia, and those readmitted after transplantation. Of the patients with GI complications, 70.9% received pharmacological treatment (89.7% with gastric protectors). Immunosuppressive therapy was also modified because of GI complications. Immunosuppressive drug dose was reduced in 18.1%, transiently stopped in 3.4%, and definitively stopped in 3.4% of cases. The drug most frequently changed was mycophenolate mofetil: dose reduction, 23.6%; transient withdrawal, 5.7%; and definitive withdrawal, 6.6%. The prevalence of GI complications in the liver transplant population was approximately 50%. GI complications showed a significant impact on the quality of life of the patients. They were related to female gender, to pretransplantation GI pathology, and posttransplantation hospital admission. These complications were frequently managed with pharmacological therapy or with changes in immunosuppressive therapy.

Combined lung-liver transplantation is a logistically challenging procedure hampered by shortage of organ donors. We describe the case of a young patient with end-stage lung disease due to of cystic fibrosis and liver cirrhosis who needed combined lung-liver transplantation. The long waiting for this caused an interesting clinical dilemma. We decided to change our policy in this situation by listing him only for the lung transplantation and to apply for a high urgent liver transplantation if the liver failed after the lung transplantation. This strategy enabled us to use lungs treated with ex vivo lung perfusion (EVLP) from an unsuitable donor after circulatory death. After conditioning for 4 h via EVLP, the pO2 was 59.7 kPa. The lungs were transplanted successfully. He developed an acute-on-chronic liver failure for which he received a successful liver transplantation 19 days after the lung transplantation. © 2014 Steunstichting ESOT.

Liver transplantation (Lt) for colorectal cancer (CRC) liver metastases is no more considered due to the poor outcome observed up to the 1990s. According to the European Liver Transplant Registry (ELTR), 1- and 5-year patient survival following Lt for CRC liver metastases performed prior to 1995 was 62% and 18%, respectively. However, 44% of graft loss or patient deaths were not related to tumor recurrence. Over the last 20 years there has been dramatic progress in patient survival after Lt, thus it could be anticipated that survival after Lt for CRC secondaries today would exceed from far, the outcome of the past experience. By utilizing new imaging techniques for proper patient selection, modern chemotherapy and aggressive multimodal treatment against metastases, long term survivors and even cure could be expected. Preliminary data from a pilot study show an overall survival rate of 94% after a median follow up of 25 months. While long term survival after the first Lt is 80% all indications confounded, 5-year survival after repeat Lt is no more than 50% to 55%. If patients transplanted for CRC secondaries can reach the latter survival rate, it could be difficult to discriminate them in the liver allocation system and live donation could be an option.

Liver transplantation for patients requiring life-support results in the lowest survival and highest costs. A ten year (1983-1993) regional experience with liver transplantation for critically ill patients was undertaken to ascertain the fate of several subgroups of patients. Of the 828 liver transplants performed at six transplant centers within the region over this period, 168 (20%) were done in patients who met today's criteria for a United Network of Organ Sharing (UNOS) status 1 (emergency) liver transplant candidate. Recipients were classified according to chronicity of disease and transplant number (primary-acute, primary-chronic, reTx-acute, reTx-chronic). Overall one-year survival was 50% for all status 1 recipients. The primary-acute subgroup (n = 63) experienced a 57% one-year survival compared with 50% for the primary-chronic (n = 51) subgroup (P = 0.07). Of the reTx-acute recipients (n = 43), 44% were alive at one year in comparison with 20% for the reTx-chronic (n = 11) group (P = 0.18). There was no significant difference in survival for the following: transplant center, blood group compatibility with donors, age, preservation solution, or graft size. For patients retransplanted for acute reasons (primary graft nonfunction (PGNF) or hepatic artery thrombosis [HAT]), survival was significantly better if a second donor was found within 3 days of relisting (52% vs. 20%; P = 0.012). Over the study period progressively fewer donor organs came from outside the region. No strong survival-based argument can be made for separating, in allocation priority, acute and chronic disease patients facing the first transplant as a status 1 recipient. Clearly patients suffering from PGNF or HAT do far better if retransplanted within 3 days. Establishing an even higher status for recipients with PGNF, perhaps drawing from a supraregional donor pool, would allow surgeons to accept more marginal donors, thus potentially expanding the pool, without significantly

Liver transplantation (LT) in overseas patients is a sensitive issue because of the possibility of organ trafficking and transplant tourism. In the Istanbul Summit, there was a call to develop standardized professional frameworks to prevent these practices. Our objectives are three-fold, to critically evaluate our professional framework, to study the demographic profiles, and to identify the outcome and impact of LT in overseas patients. Recipient and donor case records, e-mail communications, and medico-legal records were collected and analyzed for management strategy, demographic profile, donor and recipient characteristics, and outcome. Only 5% of our total LT operations were for overseas patients. Forty-two (79%) were pediatric cases for which 39 (93%) were due to biliary atresia (P<0.001). Sixty-eight percent were from the Philippines. Thirty-seven (70%) of the donors were first-degree relative. The average hospital days of a pediatric living donor liver transplant (LDLT) recipient was 65.48±28.7, and average cost was 44,602 USD. An adult LDLT recipient stayed for 52.09±11.3 days and spent around 75, 013 USD. A donor of pediatric LDLT stayed in the hospital for 17.42±5 days and spent round 8,176 USD. A donor for adult LDLT was admitted for 15.5±4 days and spent an average 9,612 USD. The total cost for recipient and donor were 56,615 USD (range, 28,976-82,056) for pediatric LDLT and 84,483 USD (range, 64,851-108,467) for adult LDLT. Actuarial survival rates were 91% at 1 year, 88% at 3 years, and 86% at 5 years and 10 years. Travelling for LDLT may be a wise and cost-effective step for patients with end-stage liver disease seeking alternative ways from their country. Our professional framework is effective to prevent practice of organ trafficking and transplant tourism. It may be useful to develop international guidelines for the practice of LT in overseas patients.

About 27,000 deaths are registered annually in the United States due to liver disease. At this time, the only definitive treatment of hepatic failure is orthotopic transplantation. However, there is a critical shortage of organs with the total waiting list for all organs currently at 100,000 requests. The number is increasing by 5% every year. Given that only organs in pristine condition are transplantable and that the hidden demand for organs as an anti-aging solution will be many times the current figures, orthotopic transplantation will always remain a limited pool. The increasing donor organ shortage requires consideration of alternative emerging technologies. Regenerative medicine may offer novel strategies to treat patients with end-stage organ failure. The ultimate aim of cell transplantation, tissue engineering, and stem cells is to regenerate tissues and organs. With the development of whole organ decellularization methods, the equation of organ shortage may dramatically change in the near future. Decellularized organs provide the ideal transplantable scaffold with all the necessary microstructure and extracellular cues for cell attachment, differentiation, vascularization, and function. New techniques to re-engineer organs may have major implications for the fields of drug discovery, regeneration biology, and ultimately organ transplantation.

We report a case of a patient with end-stage liver disease secondary to hepatitis C, complicated by a large hepatocellular carcinoma. Because of the size of the tumor exceeded the Milan criteria, he was not a candidate for liver transplantation. However, after two treatments with yttrium-90 glass microsphere infusions, the tumor became smaller and the patient's alpha-fetoprotein level dropped to normal range. He was listed for transplantation and subsequently received a deceased donor liver transplant. Two years after his transplantation, he remains tumor free and has normal alpha-fetoprotein levels. This is the first reported case in the literature of using yttrium-90 microspheres as a bridge to liver transplantation in a patient with a large hepatocellular carcinoma. This therapy should be considered in patients with cirrhosis and large hepatocellular carcinomas exceeding current size criterion, who would otherwise be good candidates for transplantation.

Early infectious complications within the first 3 months of orthotopic liver transplantation are common and are associated with significant morbidity and mortality. Here we report the first case of transfusion-acquired malaria in an orthotopic liver transplantation recipient. The patient was found to have Plasmodium ovale malaria during evaluation of a severe febrile illness. The infection was traced to a platelet transfusion and responded to treatment with chloroquine. Risk factors associated with the development of malaria infection are identifiable and should be reviewed from the recipient and donor when possible. Routes of infection in the liver transplant patient would include blood products, the organ itself, and resurgence of latent infection. Theoretically, immunosuppression may have an impact on the disease process. Clinicians caring for these patients need to have a high index of suspicion in order to diagnose and treat malaria effectively in the post-transplant setting. Although rare, malaria should be added to the list of pathogens that can infect organ transplant recipients.

We present the case of a 23-year-old man with fever of unknown origin, who developed acute liver failure 2 months after symptom onset, requiring an urgent liver transplantation. The diagnosis of adult-onset Still's disease was established after the reappearance of symptoms after transplantation, and high doses of corticosteroids were used to control disease activity. Subsequently, given the impossibility of tapering the steroid dose, interleukin-1 receptor blocking treatment was started with satisfactory outcome. We also review the published literature.

We report the first case of a liver transplant in a patient with epidermolysis bullosa acquisita and associated hepatitis B virus-hepatitis D virus cirrhosis and its inherent technical issues. Epidermolysis bullosa acquisita is an autoimmune multisystem disorder involving skin and mucosa characterized by the appearing of blisters and erosions. The more severe forms may result in nutritional compromise, anemia, osteopenia, dilated cardiomyopathy, laryngeal mucosal involvement, esophageal strictures, bladder, and kidney involvement requiring surgical intervention. Epidermolysis bullosa acquisita has become recognized as a multisystem disorder that poses several surgical challenges. This case shows that liver transplant is a feasible procedure in patients affected by epidermolysis bullosa acquisita. Patients with epidermolysis bullosa acquisita require a particular pretransplant assessment and a dedicated intra- and postoperative management of every invasive procedure that can traumatize the skin and mucosal epithelium to achieve an uneventful liver transplant. Epidermolysis bullosa acquisita does not represent a contraindication to liver transplant, and immunosuppression after transplant may favor a good systemic control of this immunologic disorder.

Our understanding of cyclosporine (CsA) administration for liver transplantation has significantly improved over the past decade. Cyclosporine is a highly lipophilic molecule, and the original galenic formulation, Sandimmune, was highly dependent on bile flow and gut motility for its absorption. Sandimmune's poor absorption profile produced erratic CsA levels after liver transplantation. A new microemulsification formulation of CsA, Neoral (CsA-ME), was developed to overcome these limitations. The NOF-1 study confirmed the superiority of CsA-ME's absorption compared with Sandimmune; CsA-ME had a more consistent and reliable absorption, with lower intrapatient variability and improved dose linearity with drug exposure as measured by area under the concentration-time curve (AUC). These advantages translated into more reliable CsA predose concentrations and less toxicity. An analysis of the pharmacokinetic data showed that 2-hour postdose CsA levels (C2) provided a better measure of immune suppression than did trough levels (C0). The LIS2T study recently confirmed and extended these data by showing equivalent efficacy between CsA-ME using C2 monitoring or tacrolimus in liver transplant patients, with a similar incidence of adverse events except for a higher rate of diabetes mellitus and diarrhea with tacrolimus. These data confirmed that the improved CsA-ME formulation, when used in conjunction with optimized drug-monitoring protocols, is well tolerated after transplantation and provides low rates of graft rejection.

Return to productive employment is often an important milestone in the recovery and rehabilitation process after liver transplantation (OLT). This literature review identifies factors associated with employment in patients who underwent OLT. We searched PubMed for articles that addressed the various factors affecting employment after OLT. The studies demonstrated improvement in the quality of life and examined factors that predicted whether patients would return to work after OLT. Demographic variable associated with posttransplant employment included young age, male sex, college degree, Caucasian race, and pretransplant employment. Patients with alcohol-related liver disease had a significantly lower rate of employment than did those with other etiologies of liver disease. Recipients who were employed after transplantation had a significantly better posttransplant functional status than did those who were not employed. Economic pressures are increasing the expectation that patients who undergo successful OLT will return to work. Thus, transplant teams need to have a better understanding of posttransplant work outcomes for this vulnerable population, and greater attention must be paid to the full social rehabilitation of transplant recipients. Specific interventions for OLT recipients should be designed to evaluate and change their health perceptions and encourage their return to work. Published by Elsevier Inc.

Familial hypercholesterolemia (FH) is an autosomal dominant disorder characterized by impaired clearance of low-density lipoprotein cholesterol. Given limitations in pharmacologic therapy and the significant morbidity and mortality associated with this disease, liver transplantation may be offered to select homozygous FH patients in childhood in an effort to slow progression of atherosclerotic cardiovascular disease. In rare cases, domino liver transplantation can be performed, transplanting the livers of patients with various metabolic disorders into elderly recipients whose projected survival precludes prolonged waiting on the transplant list. Herein, we report a case of domino liver transplantation using the liver of a 14-year-old boy with homozygous FH into a 65-year-old man with primary sclerosing cholangitis and cirrhosis who developed rapidly progressive atherosclerotic cardiovascular disease involving the arteries of his proximal bilateral lower extremities, carotid arteries and superior mesenteric artery.

Background and aims For patients with end-stage liver disease commonly used indices of nutritional status (i.e. body weight and BMI) are often inflated due to fluid overload (i.e. ascites, peripheral edema) resulting in an underdiagnosis of malnutrition. As muscle is the largest protein reservoir in the body, an estimate of muscle mass may be a more reliable and valid estimate of nutritional status. Methods Therefore, we used pre-transplant computerized tomography data of 338 liver transplant (LTX) candidates to identify muscle and fat mass based on a specific abdominal transverse section commonly used in body composition analyses and investigated the contribution of this measure to specific post-LTX outcomes. Results We found the majority, 68%, of our patients could be defined as cachetic. For men muscle mass predicted many important post-transplant outcomes including intensive care unit (ICU) and total length of stay and days of intubation. Muscle mass was a significant predictor of survival and also predicted disposition to home vs another facility. For women muscle mass predicted lengths of ICU and total stay and days of intubation but the effect was modest. Muscle mass did not predict survival or disposition for women. Conclusions As pre-transplant muscle mass was associated with many important post-operative outcomes we discuss these findings in the context of possible pre-transplant interventions to either improve or sustain muscle mass before surgery.

Although human immunodeficiency virus (HIV)-infected patients are living longer and dying less often from complications related to acquired immunodeficiency syndrome (AIDS), they are experiencing significant morbidity and mortality related to end-stage liver disease. Advances in the management of HIV disease have made it difficult to continue denying transplantation to this population based upon futility arguments alone. Patient and graft survival rates in HIV-infected study subjects appear similar to those in large transplant databases. There are no reports suggesting significant HIV disease progression. There are substantial interactions between immunosuppressants and antiretroviral drugs that require careful monitoring and dose adjustment. The evaluation and management of HIV-infected transplant candidates and recipients require excellent communication among a multidisciplinary team and the primary HIV care provider. It is critical that HIV clinicians and hepatologists are aware that liver transplantation is an option for HIV-infected patients at many transplant centers as delays in referral result in unnecessary mortality during the pretransplantation evaluation process.

One of the causes of auxiliary liver transplantation failure is the inter-liver competition between the host liver and the graft for the hepatotrophic factors of the portal blood. We have developed an experimental model of heterotopic partial (30%) liver isotransplant using Wistar rats so as to study this competition. Splenoportography and dissection demonstrate the existence of collateral circulation. The collaterals at 90 days post-transplant (PT) consisted of veins from the portal vein to the host liver (PR), paraesophageal veins (PE) and splenorenal veins (SR). At 60 days P.T., PR and SR veins but not PE ones appeared, and at 30 days P.T., there were only PR veins. Graft atrophy at 90 days P.T. was associated with a severe degree of bile duct proliferation. The gradual development of portal hypertension causes porto-systemic collateral circulation and the graft loses the portal hepatotrophic factors. The late development of the portal hypertension and the biliary proliferation could be caused by the hepatic arterial ischemia in this experimental model. Thus, as has been described in the orthotopic liver tansplantation, the heterotopic one might require a double vascularization, both portal and arterial. PMID:2278927

Background Although liver transplantation has been widely practised, post-operative bacterial infection is still a frequent complication which contributed to an increased risk of fatality. There were studies on preoperative use of probiotics for liver transplant patients and acquired reduction in postoperative sepsis and wound infection, but the relevant clinical experience with pre- and probiotics is still limited. Objectives This study is to assess fibre and probiotic use aimed at preventing bacterial sepsis and wound complications in patients undergoing liver transplantation. Study methods There were a total of sixty-seven adult patients scheduled for liver transplantation were included in a public teaching hospital. From January to December 2011, 34 continuous patients following liver transplantation were put on fibre + probiotics. In retrospectively, from January to December 2010, 33 continuous patients were collected as a control group and they were only received fibre post operation. The incidence of bacterial infections was compared in patients receiving either fibre and lactobacillus or fibre only. Statistical analysis was performed using SPSS 15. The t test, fisher’s and chi- square test was used to compare discrete variables. Results In summary, in the analysis of 67 liver transplant recipients, 8.8% group A patients developed infections compared to 30.3% group B patients. The difference between groups A and B was statistically significant in both cases. In addition, the duration of antibiotic therapy was significantly shorter in the lactobacillus-group. Wound infection was the most frequent infections and enterococci the most frequently isolated bacteria. Fibre and lactobacilli were well tolerated in most cases. The operating time, amount of intra- and post-operatively transfused units of blood, fresh frozen plasma and albumin did not differ significantly between the groups. Conclusions Combined fibre and probiotics could lower the incidence of

Blood concentrations of cyclosporine were determined in adult and pediatric patients following orthotopic liver transplantation to quantitate cyclosporine blood clearance and oral absorption. Seventeen bioavailability studies were performed following transplantation surgery in nine children and seven adults. The intravenous cyclosporine study was performed following an average dose of 2.1 mg/kg. The patients were again studied when they received the same intravenous dose plus an oral dose of cyclosporine of 8.6 mg/kg or an oral dose alone. Blood samples were collected and analyzed for cyclosporine using high-performance liquid chromatography. Cyclosporine blood clearance ranged from 29 to 203 mL/min (1.9–21.5 mL/min/kg) in children and from 253 to 680 mL/min (3.2–7.6 mL/min/kg) in adults. The mean cyclosporine clearance value was 9.3 mL/min/kg in the pediatric patients and 5.5 mL/min/kg in the adults. Cyclosporine bioavailability was less than 5% in six studies on five pediatric patients in the immediate postoperative period. The bioavailability varied from 8% to 60% in adult liver transplant patients (mean, 27%). We conclude that: (1) cyclosporine clearance is highly variable between patients, (2) pediatric patients clear the drug more rapidly than adults and therefore need a higher cyclosporine dose on a body weight basis, (3) cyclosporine is poorly and variably absorbed in liver transplant patients, and (4) cyclosporine blood concentration monitoring is essential following orthotopic liver transplantation.

Liver transplant patients frequently require large amounts of blood. The frequency and nature of their red cell (RBC) antibody problems were examined. Records were reviewed in 496 adults and 286 children undergoing 1000 consecutive transplants. Twenty-two percent of adults and 14 percent of children had RBC alloantibodies. Antibodies of potential clinical significance were found before transplant in 6.3 percent of adults and 1.0 percent of children; despite immunosuppression, they appeared 1 to 5 weeks after transplant in an additional 7.5 and 5.2 percent respectively. These antibodies probably represented secondary immune responses. Of 58 transplant patients with prior potentially significant antibodies, 8 required 7 to 110 units of antigen-untyped blood after 8 to 28 units of antigen-negative blood; of these patients, one had subsequent hemolysis. Positive direct antiglobulin tests in 24 percent of adults and 10 percent of children were most often thought to be due to nonspecific adsorption of IgG. Anti-recipient ABO antibodies developed in 22 of 60 (37%) evaluable ABO-unmatched grafts; 13 cases had associated hemolysis. In all, 36 percent of adults and 20 percent of children had diverse RBC antibody problems. Resolution of these problems is an important part of the laboratory support necessary for a liver transplantation program. PMID:2660334

We report a case of a 45-year-old male patient diagnosed with liver cirrhosis by hepatitis C and alcohol, with a Child-Pugh score C and a model for end-stage liver disease (MELD) score of 27, and submitted to liver transplantation. The subject underwent insertion of the pulmonary artery catheter (PAC) in the right internal jugular vein, with technical difficulty concerning catheter advance. There was sudden hypotension, increase in central venous pressure (CVP), and decrease in SvO2 15 minutes after the PAC had been inserted, followed by cardiorespiratory arrest in pulseless electrical activity (PEA), which was promptly assisted with resuscitation. Pericardiocentesis was performed without success, so the individual was subjected to a subxiphoid pericardial window, which led to output of large amounts of blood as well as PEA reversal to sinus rhythm. Sternotomy was performed; rupture of the apex of the right ventricle (RV) was detected, and suture of the site was accomplished. After hemodynamic stabilization, the patient was transferred to the ICU, where he developed septic shock and, despite adequate therapy, died on the eighteenth day after ICU admission. PMID:20066172

Over the sixteen year history of liver transplantation (LT) at Mayo Clinic in Jacksonville, Florida (MCF), we have maintained a practice devoted to excellence in pre- and post-LT management for patients suffering from end stage liver disease. With an emphasis on quality, MCF has made several adjustments with the goal of better utilizing marginal grafts for both successful post-transplant outcomes and minimizing waitlist mortality. This systematic approach is most exemplified in our experience with donation after cardiac death (DCD) liver allografts. Understanding the events during procurement has been critical to reducing the complications associated with donor warm ischemia time that are unique to DCD allografts. Better matching of donors to recipients has helped identify patients who are safe to receive more marginal grafts with successful patient and graft survival. Recognizing the spectrum of degree of sickness in patients undergoing LT, we implemented a multidisciplinary approach that allows for the avoidance of the intensive care unit after LT. In these ways, MCF continues to distinguish itself as an innovator in the field of transplantation for the benefit of continued better care for our patients suffering from end stage liver disease.

In the United States, livers for transplantation are distributed within donation service areas (DSAs). In DSAs with multiple transplant centers, competition among centers for organs and recipients may affect recipient selection and outcomes in comparison with DSAs with only 1 center. The objective of this study was to determine whether competition within a DSA is associated with posttransplant outcomes and variations in patients wait-listed within the DSA. United Network for Organ Sharing data for 38,385 adult cadaveric liver transplant recipients undergoing transplantation between January 1, 2003 and December 31, 2009 were analyzed to assess differences in liver recipients and donors and in posttransplant survival by competition among centers. The main outcome measures that were studied were patient characteristics, actual and risk-adjusted graft and patient survival rates after transplantation, organ quality as quantified by the donor risk index (DRI), wait-listed patients per million population by DSA, and competition as quantified by the Hirschman-Herfindahl index (HHI). Centers were stratified by HHI levels as no competition or as low, medium (or mid), or high competition. In comparison with DSAs without competition, the low-, mid-, and high-competition DSAs (1) performed transplantation for patients with a higher risk of graft failure [hazard ratio (HR) = 1.24, HR = 1.26, and HR = 1.34 (P < 0.001 for each)] and a higher risk of death [HR = 1.21, HR = 1.23, and HR = 1.34 (P < 0.001 for each)] and for a higher proportion of sicker patients as quantified by the Model for End-Stage Liver Disease (MELD) score [10.0% versus 14.8%, 20.1%, and 28.2% with a match MELD score of 31-40 (P < 0.001 for each comparison)], (2) were more likely to use organs in the highest risk quartile as quantified by the DRI [18.3% versus 27.6%, 20.4%, and 31.7% (P ≤ 0.001 for each)], and (3) listed more patients per million population [18 (median) versus 34 (P = not significant), 37 (P

A program of normothermic ex situ liver perfusion (NESLiP) was developed to facilitate better assessment and use of marginal livers, while minimizing cold ischemia. Declined marginal livers and those offered for research were evaluated. Normothermic ex situ liver perfusion was performed using an erythrocyte-based perfusate. Viability was assessed with reference to biochemical changes in the perfusate. Twelve livers (9 donation after circulatory death [DCD] and 3 from brain-dead donors), median Donor Risk Index 2.15, were subjected to NESLiP for a median 284 minutes (range, 122-530 minutes) after an initial cold storage period of 427 minutes (range, 222-877 minutes). The first 6 livers were perfused at high perfusate oxygen tensions, and the subsequent 6 at near-physiologic oxygen tensions. After transplantation, 5 of the first 6 recipients developed postreperfusion syndrome and 4 had sustained vasoplegia; 1 recipient experienced primary nonfunction in conjunction with a difficult explant. The subsequent 6 liver transplants, with livers perfused at lower oxygen tensions, reperfused uneventfully. Three DCD liver recipients developed cholangiopathy, and this was associated with an inability to produce an alkali bile during NESLiP. Normothermic ex situ liver perfusion enabled assessment and transplantation of 12 livers that may otherwise not have been used. Avoidance of hyperoxia during perfusion may prevent postreperfusion syndrome and vasoplegia, and monitoring biliary pH, rather than absolute bile production, may be important in determining the likelihood of posttransplant cholangiopathy. Normothermic ex situ liver perfusion has the potential to increase liver utilization, but more work is required to define factors predicting good outcomes.

Acute liver failure is a life-threatening condition in the absence of liver transplantation option. The aetiology of liver failure is the most important factor determining the probability of native liver recovery and prognosis of the patient. Extracorporeal liver assist devices like MARS (Molecular Adsorbent Recirculating System) may buy time for native liver recovery or serve as bridging therapy to liver transplantation, with reduced risk of cerebral complications. MARS treatment may alleviate hepatic encephalopathy even in patients with a completely necrotic liver. Taking this into account, better prognostic markers than hepatic encephalopathy should be used to assess the need for liver transplantation in acute liver failure.

Orthotopic liver transplantation for other diseases typically results in a coincidental cure for hemophilia A and B; however, long-term outcomes of liver transplant in hemophilia C are not very well described. Herein, the authors report a patient of severe congenital factor XI (FXI) deficiency who received an orthotopic liver transplant. The authors discuss the perioperative management and long-term outcomes. The normalization of his FXI levels confirms that the liver is the most clinically relevant site of synthesis of FXI.

The division of a single hepatic allograft to create two reduced-size grafts has been reported with decreased graft survival (50%) resulting in decreased enthusiasm for this approach. The authors reviewed their experience with 12 recipients of this procedure to evaluate the outcome of the children electively undergoing transplant with the "leftover liver." A retrospective review of six pairs of children receiving part of one hepatic allograft included donor anatomy, recipient operation, and allograft and patient outcomes. Recipient pairs were selected according to blood type compatibility, medical priority, and size restrictions of the larger right lobe and the smaller left lateral segment. Patient and graft survival were compared with elective and urgent patients undergoing whole or reduced-size transplants. Six donors weighed 71.8 +/- 17.4 kg and were 22.6 +/- 11.0 years of age. Recipients of the right lobe were 11.8 +/- 4.2 years of age and weighed 41.9 +/- 14 kg. Recipients of the left lateral segment were 1.81 +/- 1.1 years of age and weighed 9.85 +/- 1.82 kg. Six patients were initially offered the donor allograft because of their hospitalization, critical illness or waiting time. Six additional patients electively underwent transplantation with the leftover liver. Donor organs were screened for normal arterial anatomy. Division of the allograft was performed on the back table in the falciform groove. Generally the left lateral segment graft received the major portion of the hepatic artery and the right lobe the major portion of the portal vein. Five of six (83%) elective patients, two receiving the right lobe and three receiving the left lateral segment had prompt recovery and left the hospital without surgical complication. One recipient of a right lobe transplant died from primary allograft nonfunction. These results are not different from the outcomes of all elective patients who underwent transplantation with whole or reduced-sized transplants in the

Cavo-portal transposition (CPT) at liver transplantation (LTx) allows portal revascularization of the liver in recipients in whom portal system thrombosis does not allow performance of porto-portal anastomosis. The aim was to present the cases of 2 children who underwent LTx and CPT in our institution. 1. A 10-year-old boy, after Kasai procedure and living donor LTx, was qualified for retransplantation 9 years after first LTx complicated with late portal vein thrombosis, portal hypertension, hypersplenism, and multiple GI bleeding episodes, after splenectomy and meso-caval shunt preventing GI bleeding. At retransplant surgery, CPT was done. Actual follow-up was 40 months. Doppler ultrasound and angio CT show normal flow within the graft's portal vein. Biochemical parameters were within normal range. There was no bleeding from the gastrointestinal tract. 2. A 14-month-old child after Kasai procedure was qualified for living donor liver transplantation. During surgery, thrombosis of the recipient portal system was found, which was not diagnosed before. The CPT was done. There were no complications during the postoperative course. The actual follow-up was 32 months, and the patient is doing well, with normal liver and renal function, without hypersplenism or ascites. There was no gastrointestinal bleeding. Doppler ultrasound showed normal intrahepatic portal and arterial flow in the transplanted liver. Cavo-portal transposition is an important option in portal vein revascularization in liver transplant recipients without access to the portal system. Long-term observation of these 2 cases did not show any late problems (e.g., bleeding from the gastrointestinal tract, renal function, hyperammonemia, ascites) related to cavo-portal transposition.

Liver transplantation (LT) is an important component in the therapeutic armamentarium of managing end-stage liver disease. In North American children, biliary atresia remains the most common indication for LT compared to hepatitis C in adults, while hepatoblastoma is the most common liver tumor requiring LT, versus Hepatocellular carcinoma in adults. Rejection, lymphoproliferative disease, renal insufficiency, metabolic syndrome, recurrent disease, 'de novo' autoimmune hepatitis and malignancy require careful surveillance and prompt action in adults and children after LT. In children, specific attention to EBV viremia, growth, development, adherence and transition to the adult services is also required. Antibody mediated rejection and screening for donor specific antibodies is becoming important in managing liver graft dysfunction. Biomarkers to identify and predict tolerance are being developed. Machine perfusion and stem cells (iPS) to synthesize organs are generating interest and are a focus for research.
The transplantation of hepatocytes could be an alternative therapeutic option to the whole organ transplantation for the treatment of end-stage liver diseases. However, this cell-based therapy needs the understanding of the molecular mechanisms to improve efficacy. This chapter includes a detailed method of a rat model for liver regeneration studies after age-dependent hepatocyte transplantation.

Brucellosis is considered the most widespread zoonosis in the world. It has been reported that the prevalence of seropositivity among the Turkish population varies from 3% to 14%. We present a case of brucellosis after pediatric liver transplantation. A 15-year-old boy with the diagnosis of neuro Wilson's disease underwent deceased-donor liver transplantation. The postoperative immunosuppressive protocol consisted of steroids and tacrolimus. Two months after the operation the patient experienced fever to 40°C. The patient complained of poor appetite, headache, and diarrhea. He had had pancytopenia. Despite administration of appropriate antibiotics, antiviral and antifungal agents, fever persisted for > 1 month. Multiple blood, urine, stool, and sputum cultures were negative. Bone marrow aspirate revealed hypocellularity. Liver biopsy was performed, but rejection was not observed on biopsy specimen. Brucella serology was positive and Brucella agglutination titer was 1:320. Bone marrow culture was positive for Brucella but blood culture was negative. The patient was then treated with oral doxycycline and rifampin for 8 weeks. No previous case report about Brucella infection after liver transplantation has appeared in the literature, to our knowledge; our case is presented as the first. Bone marrow hypoplasia is a rare feature of Brucella infection. Our patient with brucellosis and pancytopenia had had hypocellular bone marrow. The clinical and hematologic findings resolved with treatment of the infection. Brucella infection should be suspected in liver transplanted recipients with fever of unknown origin, especially in a recipient who has lived in an endemic area. Brucella also should be considered as a possible diagnosis in patients with pancytopenia.

Any use of alcohol in the years following liver transplantation (LTX) approaches 50% of patients transplanted for alcoholic liver disease (ALD). We collected detailed prospective data on alcohol consumption following LTX for ALD to investigate ongoing patterns of use. Using trajectory modeling we identified four distinct alcohol use trajectories. One group had minimal use over time. Two other groups developed early onset moderate to heavy consumption and one group developed late onset moderate use. These trajectories demonstrate that alcohol use varies based on timing of onset, quantity, and duration. Using discriminant function analysis, we examine characteristics of recipient’s pre-LTX alcohol histories and early post-LTX psychological stressors to identify the profile of those at risk for these specific trajectories. We discuss the relevance of these findings to clinical care and preliminarily to outcomes. PMID:20726963

Liver transplant (LT) is a major surgical undertaking involving major fluid shifts, hemodynamic instability and metabolic derangements in a patient with preexisting liver failure and multisystemic derangements. Monitoring and organ support initiated in the preoperative phase is continued intraoperatively and into the postoperative phase to ensure an optimal outcome. As cardiovascular events are the leading cause of non-graft related death among LT recipients, major emphasis is placed on cardiovascular monitoring. The other essential monitoring are the continuous assessment of coagulapathy, extent of metabolic derangements, dyselectrolytemis and intracranial pressure monitoring in patients with fulminant hepatic failure. The type and extent of monitoring differs with need according to preexisting child status of the patient and the extent of systemic derangements. It also varies among transplant centers and is mainly determined by individual or institutional practices. PMID:25755443

Liver transplantation allows long-term survival (10 years or more) in 75% of children receiving transplants before 2000. The risk of mortality after the first year is 4-10% in the next 10-20 years. Chronic rejection affects 6%. The need for late retransplantation is 3-5%. However, the follow-up of these patients involves the management of diverse problems in the graft (immunological, biliary, vascular) and others related to the use of immunosuppressants (renal dysfunction, lymphoproliferative syndrome). The transition from pediatric to adult care generates special needs. Adolescence and young adulthood are associated with a lack of compliance. Adult specialists should be aware of the special features of the original diagnosis and the surgical techniques used in childhood transplantation. Final quality of life is good overall but is lower than that in healthy young persons.

Despite the importance of haemodynamic management in patients undergoing liver transplantation, there is currently no consensus on the most appropriate type of monitoring to use. In this context, transoesophageal echocardiography can provide useful information to professionals, although their use constraints prevent further spread today.

Hepatocellular carcinoma (HCC) recurs with a reported frequency of 12%-18% after liver transplantation. Recurrence is associated with a mortality rate exceeding 75%. Approximately one-third of recurrences develop in the transplanted liver and are therefore amenable to local therapy. A variety of treatment modalities have been reported including resection, transarterial chemo-embolization (TACE), radiofrequency ablation (RFA), ethanol ablation, cryoablation, and external beam irradiation. Goals of treatment are tumor control and the minimization of toxic effect to functional parenchyma. Efficacy of treatment is mitigated by the need for ongoing immunosuppression. Yttrium-90 microspheres have been used as a treatment modality both for primary HCC and for pre-transplant management of HCC with promising results. Twenty-two months after liver transplantation for hepatitis C cirrhosis complicated by HCC, a 42-year old man developed recurrence of HCC in his transplant allograft. Treatment of multiple right lobe lesions with anatomic resection and adjuvant chemotherapy was unsuccessful. Multifocal recurrence in the remaining liver allograft was treated with hepatic intra-arterial infusion of yttrium-90 microspheres (SIR-Spheres, Sirtex Medical Inc., Lake Forest, IL, USA). Efficacy was demonstrated by tumor necrosis on imaging and a decrease in alpha-fetoprotein (AFP) level. There were no adverse consequences of initial treatment. PMID:17007031

There is wide variation in the management of coagulation and blood transfusion practice in liver transplantation. The use of blood products intraoperatively is declining and transfusion free transplantations take place ever more frequently. Allogenic blood products have been shown to increase morbidity and mortality. Primary haemostasis, coagulation and fibrinolysis are altered by liver disease. This, combined with intraoperative disturbances of coagulation, increases the risk of bleeding. Meanwhile, the rebalancing of coagulation homeostasis can put patients at risk of hypercoagulability and thrombosis. The application of the principles of patient blood management to transplantation can reduce the risk of transfusion. This includes: preoperative recognition and treatment of anaemia, reduction of perioperative blood loss and the use of restrictive haemoglobin based transfusion triggers. The use of point of care coagulation monitoring using whole blood viscoelastic testing provides a picture of the complete coagulation process by which to guide and direct coagulation management. Pharmacological methods to reduce blood loss include the use of anti-fibrinolytic drugs to reduce fibrinolysis, and rarely, the use of recombinant factor VIIa. Factor concentrates are increasingly used; fibrinogen concentrates to improve clot strength and stability, and prothrombin complex concentrates to improve thrombin generation. Non-pharmacological methods to reduce blood loss include surgical utilisation of the piggyback technique and maintenance of a low central venous pressure. The use of intraoperative cell salvage and normovolaemic haemodilution reduces allogenic blood transfusion. Further research into methods of decreasing blood loss and alternatives to blood transfusion remains necessary to continue to improve outcomes after transplantation. PMID:24876736

We have previously reported that a graft volume (GV) > 30% of the recipient's standard liver volume (SLV) can meet the recipient's metabolic demands. Here we report our experience with adult-to-adult living donor liver transplantation using left side grafts < 35% of the recipient's SLV. Of 143 adult living donor liver transplants, 13 auxiliary partial orthotopic liver transplants, 8 right side grafts, and 2 retransplantation cases were excluded. The resulting 120 cases were divided into 2 groups: group S consisted of 33 patients who received liver grafts < 35% of their SLV, and group L consisted of 87 patients who received liver grafts > or = 35% of their SLV. Patient characteristics, postoperative liver function, duration of hospital stay, and recipient survival rates were compared between the 2 groups. There were no significant differences between groups in recipient or donor background characteristics. The mean GV/SLV ratio of group S was 31.8%, whereas that of group L was 42.5%. There were no significant differences in the postoperative serum total bilirubin levels, prothrombin time international normalized ratio, daily ascites volume, or duration of postoperative hospital stay between the groups. The 1- and 5-year survival rates in group S were 80.7% and 64.2%, respectively, whereas those of group L were 90.8% and 84.9%, respectively, with no significant difference between groups. In conclusion, graft size was not considered to be the only cause of so-called small-for-size graft syndrome, and left side grafting appears to be the procedure of choice for adult-to-adult living donor liver transplantation because of the lower risk to donors in comparison with right lobe grafting.

Calcineurin inhibitor (CNI) combined with mycophenolate mofetil (MMF) and steroid is mainly used as immunosuppressive therapy after the living-donor liver transplantation (LDLT). However, the nephrotoxicity caused by CNI remains a critical problem for patients with chronic renal failure, especially on early postoperative period. A 62-year-old woman with decompensated liver cirrhosis secondary to hepatitis B (Child-Pugh C, MELD score 11 points) and chronic renal failure due to diabetic nephropathy (Cr 1.56 mg/dl, GFR 27 ml/min/1.73 m2) experienced LDLT. During the reconstruction of hepatic vein, the supra-and infra-hepatic vena cava was totally clamped. The estimated right lobe liver graft volume was 540 g, representing 51.3% of the standard liver volume of the recipient. Because of the perioperative renal dysfunction due to diabetic nephropathy and the total clamping the vena cava which induced the congestion kidney, MMF (1500 mg/day) and steroid (250 mg/day converted into predonisolone) were mainly introduced as an immunosuppressive therapy after LDLT. The low-dose CNI, tacrolimus also induced the nephrotoxicity and was given for only a short time. Finally, according to the postoperative renal function, the low-dose CNI, cyclosporin (50 mg/day) was able to be added to the introduced immunosuppressive therapy. After having left the hospital, MMF (1500 mg/day), steroid (20 mg/day converted into predonisolone) and cyclosporin (75 mg/day) continued to be given as the immunosuppressive therapy and neither acute graft rejection nor drug-induced renal dysfunction was occurred. This is a case report of introducing with mainly MMF and steroid as an immunosuppressive therapy after LDLT for a patient with perioperative renal dysfunction.

AEs during immunosuppressive treatment with tacrolimus are very common. We retrospectively evaluated FK safety and efficacy in a large pediatric liver transplant cohort in Latin America. During 2-year follow-up, we analyzed data from patients who underwent liver transplantation over the period 2010-2012 and recorded FK exposure, AEs, and AR episodes. AEs were classified according causality and severity. Tacrolimus exposure before and during AE was compared using Wilcoxon matched-pairs test. Kaplan-Meier curves were used for survival analysis. In total, 46 patients (out of 72 patients) experienced 69 AEs, such as hypomagnesemia (49%), PTLD (6%), hypertension (6%), and/or nephrotoxicity (22%). 43% of AEs were classified as moderate or serious, and 89% were assigned as probable or definitive. Patients who had one or more AR episodes accounted for 65%. The 12-month acute rejection-free survival was 41% (95% CI, 30.1%-53.1%). A significant difference was observed in FK trough concentrations before and during hypomagnesemia and nephrotoxicity (P<.05). This study is the first report of FK safety in a large group of pediatric liver transplant patients in Latin America. Children experience AEs, even in protocols with low FK doses. Therapeutic monitoring is an important tool to manage immunosuppressive schemes containing tacrolimus in vulnerable populations. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

A 20-year-old woman was admitted to an emergency hospital after ingesting 66 g of acetylsalicylic acid in a suicide attempt. Although she was treated with gastric lavage, oral activated charcoal, and intravenous hydration with sodium bicarbonate, her hepatic and renal function gradually deteriorated and serum amylase levels increased. Steroid pulse therapy, plasma exchange, and continuous hemodiafiltration did not yield any improvement in her hepatic or renal function, and she was transferred to our hospital for living donor liver transplantation. Nine days after drug ingestion, she developed hepatic encephalopathy: thus, we diagnosed the patient with acute liver failure with hepatic coma accompanied by acute pancreatitis due to the overdose of acetylsalicylic acid. Living donor liver transplantation was immediately performed using a left lobe graft from the patient's mother. Following transplantation, the patient's renal and hepatic function and consciousness improved, and she was discharged. In this report, we describe a rare case of acetylsalicylic acid-induced acute liver failure with acute hepatic coma and concomitant acute pancreatitis and acute renal failure, which were treated successfully with emergency living donor liver transplantation.

Background Acute liver failure is associated with a high mortality rate and the main purposes of treatment are to prevent cerebral edema and infections, which often are responsible for patient death. The orthotopic liver transplantation is the gold standard treatment and improves the 1-year survival. Aim To describe an alternative technique to auxiliary liver transplant on acute liver failure. Method Was performed whole auxiliary liver transplantation as an alternative technique for a partial auxiliary liver transplantation using a whole liver graft from a child removing the native right liver performed a right hepatectomy. The patient met the O´Grady´s criteria and the rational to indicate an auxiliary orthotopic liver transplantation was the acute classification without hemodynamic instability or renal failure in a patient with deterioration in consciousness. Results The procedure improved liver function and decreased intracranial hypertension in the postoperative period. Conclusion This technique can overcome some postoperative complications that are associated with partial grafts. As far as is known, this is the first case of auxiliary orthotopic liver transplantation in Brazil. PMID:26176253

Cirrhosis caused by alcohol-associated liver disease is a common indication for liver transplantation worldwide. Patients with alcohol-associated liver disease who undergo liver transplantation face multiple challenging comorbid medical issues that enhance the potential for perioperative and postoperative complications. Awareness of these issues and appropriate therapeutic intervention may minimize the negative effect of these complications on posttransplantation survival. This article reviews important posttransplantation problems in patients transplanted for alcohol-associated liver disease.

From February 1986 to July 1994, 81 hepatic transplantations were performed in 73 children, with an overall patient survival rate of 83%. Forty-two patients received whole-liver grafts (WLG) and 39 had reduced-size grafts (RSG). The mean patient weight was 19.7 kg, with 29 patients weighing less than 10 kg. Seventeen vascular complications (21%) occurred in 13 children: 8 (10%) had hepatic artery thrombosis (HAT), 5 (6%) had portal vein thrombosis (PVT), 1 had both HAT and PVT (1%), and 3 (4%) had aortic conduit perforation (ACP). There was no significant difference in the incidence of HAT between RSG (5%) and WLG (14%) or between children weighing less than 10 kg (10%) and those weighing more than 10 kg (10%). The site of arterial reconstruction, end-to-end to the recipient common hepatic artery or end-to-side to the infrarenal aorta, had no significant effect on the occurrence of HAT (7% v 8%), but HAT occurred in 2 of 6 cases (33%) in which an aortic conduit was used. PVT documented in 5 cases (6%) was associated with technical complications (2), preduodenal portal vein (2), and a circulating cardiolipid antibody (1), and required thrombectomy, with no graft loss. Combined HAT and PVT was found in one patient 2 years postretransplantation for HAT. Although graft function is normal, portal hypertension persists. The aortic conduit, used in six patients, led to arterial perforation (3), HAT (2), and death (2). Of the 8 cases of HAT, 1 was diagnosed during autopsy and 7 occurred within 30 days and required retransplantation (6) or thrombectomy with rearterialization (1).(ABSTRACT TRUNCATED AT 250 WORDS)

Liver transplantation has become the treatment of choice for acute or chronic liver disease. Because the liver acts as an innate immunity-dominant organ, there are immunological differences between the liver and other organs. The specific features of hepatic natural killer (NK), NKT and Kupffer cells and their role in the mechanism of liver transplant rejection, tolerance and hepatic ischemia-reperfusion injury are discussed in this review.

In the recent decade the subject of general hepatology has undergone significant upgrading. Several breakthrough discoveries have lead to substantial improvement in the antiviral treatment of viral hepatitis, the therapy of hepatocellular carcinoma and the development of noninvasive diagnosis of the severity of liver disease. Nonalcoholic fatty liver disease (NAFLD] is now established as one of the most common causes of chronic liver disease in the Western world. NAFLD can progress to cirrhosis and its associated complications. This issue of "Harefuah" is dedicated to the current knowledge and challenges in liver disease and transplantation and to novel discoveries in this field. Two new important guidelines of the Israeli Association for the Study of the Liver are published in this issue, the first deals with the management of ascites and its complications and the second relates to the innovative antiviral treatment of chronic hepatitis C virus infection. An extensive review on this latter subject is also included, summarizing the major breakthroughs in this field: the development of the new direct acting antiviraL agents and the role of IL28B polymorphism in the response to treatment. One article argues the concept of the high hepatitis B virus (HBV) vertical transmission in an Arab cohort in Israel, while another paper provides data on a significantly improved response rate to antiviral therapy in HIV-HCV co-infected patients. Increased serum level of lipoprotein-associated phospholipase A2 level, an independent predictor of coronary heart disease, was detected in patients with nonalcohoLic fatty liver disease [NAFLD] in another article. The issue also provides encouraging data showing that following two decades of liver transplantation in Israel, the survival rate has improved. Several additional articles in the issue shed further light on recent discoveries in the field of hepatology.

Liver grafts from hepatitis B surface antigen (HBsAg) positive donors could have potential to increase the donor pool. However, knowledge is extremely limited in this setting because currently available data are mostly from case reports. We aimed to assess the outcomes and experiences of liver transplantation from HBsAg positive donors in a single centre study. From January 2010 to February 2013, 42 adult patients underwent liver transplantation from HBsAg positive donors and 327 patients from HBsAg negative ones. The outcomes including complications and survival of two groups were compared and antiviral therapy retrospectively reviewed. HBsAg positive liver grafts were more likely to be allocated to patients with hepatitis B (HBV)-related diseases. Post-transplant evaluation showed similar graft function regaining pace and no differences in complications such as primary non-function, acute rejection and biliary complications. Patient and graft survivals were comparable to that of HBsAg negative grafts. Furthermore, HBsAg persisted after transplant in all patients that received positive grafts. The donor HBV serum status determined the one of the recipient after transplantation. No HBV flare-ups were observed under antiviral therapy of oral nucleotide analogues, regardless of using hepatitis B immunoglobulin combination. Utilization of HBsAg positive liver grafts seems not to increase postoperative morbidity and mortality. Therefore it is a safe way to expand the donor pool when no suitable donor is available. Our experience also suggests that hepatitis B immunoglobulin should be abandoned in recipients of HBsAg positive liver grafts, in whom HBV prophylaxis could be the only oral antiviral therapy.

Maintaining hepatic inflow and appropriate venous drainage is important for maximizing the capacity of the retrieved graft in liver transplantation. Here, we report a successful case of multiple hepatic vein (HV) reconstruction using an all-in-one sleeve patch graft of the autologous great saphenous vein to ensure adequate blood flow through the HV. A patient with hepatocellular carcinoma caused by hepatitis C virus-induced cirrhosis underwent living donor liver transplantation using a right lobe graft. A preoperative dynamic computed tomography scan and intraoperative findings revealed that the graft had three middle HV tributaries, a superficial vein, segment VIII HV (V8), and segment V HV (V5). The openings of the superficial vein and V8 were located very close to that of the right hepatic vein (RHV) in the cutting surface. Each HV had significant diameter and drainage territory requiring reconstruction. An autologous great saphenous vein was used to create a sleeve patch to incorporate the close-packed HV openings. The autologous sleeve patch graft was sutured to the openings of the RHV and the superficial vein and the hole created on the sleeve patch graft was anastomosed to the openings of V8 directly on the back table to create an all-in-one sleeve patch. For the V5 reconstruction, the recipient's intrahepatic portal vein graft was used to create an interpositional conduit from the recipient's V5 to the inferior vena cava. The postoperative course was uneventful and postoperative studies revealed good graft function with excellent blood flow in the HV. Copyright © 2014 Elsevier Inc. All rights reserved.

Oral ulcers are a frequent problem in transplant medicine. It is important to consider infectious etiologies, exacerbated by the immunosuppressive treatment, but other etiologies are also possible, like adverse drug reactions. Mycophenolate mofetil (MMF) is an immunosuppressive medication that has been used in combination with calcineurin inhibitors and steroids. Reports of renal transplant patients with oral ulcers related to MMF have appeared lately and herein we have described 2 cases in liver transplant patients. Their oral ulcers resolved quickly after suspension of the medication. Our 2 cases in liver transplant patients represented a unique setting for this type of complication.

A retrospective multicenter study has been conducted to evaluate domino liver transplantations (DLTs) in Germany. The study provides insight into survival and features having an impact on the assessment of neuropathy after DLT. In addition, a neurologic follow-up program with a scheme to estimate the likelihood of de novo amyloidosis is presented. A series of 61 DLTs at seven transplant centers in Germany was enrolled. The mean age of domino recipients at the time of transplantation was 58 years, 46 of them being men, and 15 being women. The median follow-up was 46 months. The overall 1-, 3-, and 5-year survival of domino recipients was 81.6%, 70.8% and 68.8%, respectively. Causes of death were primarily not related to familial amyloidosis. The main indication of DLT was hepatocellular carcinoma. Two of the reported domino recipients developed symptoms and signs of de novo amyloidosis within 10 years after transplantation. A total of 30 domino graft recipients (49.18%) presented with diabetes post transplantation. In conclusion, an advanced follow-up program is crucial to evaluate the risk of transmitting familial amyloidosis by DLT and to establish more strict selection criteria for domino recipients. © 2013 Steunstichting ESOT.

Hepatocellular carcinoma is the most common liver malignancy. Salvage liver transplantation (SLT) is viewed as a feasible cure for recurrence of HCC after resectomy, but the effect is under dispute. A retrospective study examined data at Renji Hospital for 239 transplants from January 2006 to December 2015, including 211 who received primary liver transplantation (PLT) and 28 who underwent SLT. A multivariable cox regression model was employed to pick out relative factors to overall survival (OS) and recurrence free survival (RFS). Propensity score matching (PSM) was used to balance the bias. Both OS and RFS were worse in SLT group than in PLT group, especially for those patients within Milan criteria. Our study demonstrates that SLT bears higher risk of recurrence and death than PLT, indicating that SLT should be given a more careful thought at performance. PMID:28294176
Rapid Virological Response After Early Treatment with a Combined Therapy of Ledipasvir and Sofosbuvir in HCV Genotype 4 After Living Donor Liver Transplantation in a HCC Downstaged Patient: Case Report and Review of the Literature
Obed, Aiman; Bashir, Abdalla; Jarrad, Anwar
Patient: Male, 54 Final Diagnosis: HCC with portal vein Symptoms: Liver failure Medication: — Clinical Procedure: Hepatitis c treatment • hcc tratment Specialty: Transplantology Objective: Unusual clinical course Background: Hepatitis C virus (HCV) genotype 4 (GT-4) is widespread in the Middle East, where it is responsible for the majority of HCV infections. It shows moderate treatment response rates when compared to other genotypes in the current era of interferon-based regimens. However, in the era of direct acting antiviral (DAA) drugs, its response is at least as good as observed for HCV genotypes 1–3. Case Report: We present a case of a 44-year-old patient with HCV cirrhosis. Since 2007, he has been treated for HCV infection with multiple ineffective regimens of interferon (INF) and ribavirin. A liver biopsy in 2010 revealed stage 5-6/6 indicating cirrhosis, which was later complicated by the occurrence of portal vein thrombosis and a large hepatocellular carcinoma (HCC) (maximum diameter 9 cm). The patient was successfully treated with sorafenib, transcatheter arterial chemoembolization (TACE), and radio-frequency ablation. After four TACE procedures, the patient’s AFP (alpha-fetoprotein) decreased remarkably and almost normalized. The HCC disappeared radiologically as shown by triple phase CT, MRI with contrast, and PET-CT. He successfully underwent a living donor liver transplantation. Four weeks post liver transplantation he started treatment with sorafenib, and switched from tacrolimus to Rapamune (sirolimus) as immunosuppressant therapy. Ten weeks after liver transplantation, HCV treatment was introduced along with ledipasvir and sofosbuvir due to his increasing liver enzyme levels. A rapid viral response was achieved after 14 days. In total, the patient received 12 weeks of this treatment. Conclusions: This case study might be of significance in informing early management and personalized treatment of patients with recurrent HCV GT-4 infections

With the technical advances and improvements in perioperative management and immunosuppressants, liver transplantation is the standard treatment for patients with end-stage liver diseases. In Asia, a shortage of deceased donor liver grafts is the universal problem to be faced with in all transplant centres. Many surgical innovations are then driven to counteract this problem. This review focuses on 3 issues that denote the development of liver transplantation in Asian countries. These include living donor liver transplantation (LDLT), split liver transplantation (SLT) and liver transplantation for hepatocellular carcinoma (HCC). Minimal graft weight, types of liver graft to donate and the inclusion of the middle hepatic vein with the graft are the main issues to be established in LDLT. The rapid growth and wide dissemination of LDLT has certainly alleviated the supply-and-demand problem of liver grafts in Asia. SLT is another attractive approach. Technical expertise, donor selection and graft allocation are the main determinants for its success. Liver transplantation plays a key role in the management of HCC in Asia. LDLT would be the main strategy in this aspect. The issue of extending the selection criteria for HCC patients for LDLT is still controversial. On the whole, future developments to increase the donor pool for the expanding recipient need in Asia would involve transplantation from non-heart beating donor and ABO incompatible transplantation.

Porphyrias are a group of eight metabolic disorders, each resulting from a mutation that affects an enzyme of the heme biosynthetic pathway. Porphyrias are classified as hepatic or erythropoietic, depending upon the site where the gene defect is predominantly expressed. Clinical phenotypes are classified as follows: (1) acute porphyrias with neurovisceral symptoms: acute intermittent porphyria; delta amino-levulinic acid hydratase deficiency porphyria; hereditary coproporphyria; and variegate porphyria and (2) cutaneous porphyrias with skin blistering and photosensitivity: porphyria cutanea tarda; congenital erythropoietic porphyria; hepatoerythropoietic porphyria and both erythropoietic protoporphyrias: autosomal dominant and X-linked. Liver transplantation (LT) may be needed for recurrent and/or life-threatening acute attack in acute intermittent porphyria or acute liver failure or end-stage chronic liver disease in erythropoietic protoporphyria. LT in acute intermittent porphyria is curative. Erythropoietic protoporphyria patients needing LT should be considered for bone marrow transplantation to achieve cure. This article provides an overview of porphyria with diagnostic approaches and management strategies for specific porphyrias and recommendations for LT with indications, pretransplant evaluation, and posttransplant management. © 2014 by the American Association for the Study of Liver Diseases.

Organ shortage remains a major problem in liver transplantation for which the number of patients on the waiting list is superior to the number of liver grafts harvested each year. In 2007, 1061 liver transplantations have covered 78.7% of the needs for 1348 new candidates. Improvement of the results (5 year-survival 74.9% and 63% at 10 years) do not influence the number of major indications (hepatocellular carcinoma, hepatitis C virus, alcohol), despite a slight decrease in the rate of activity of 1 to 2% per year. Introduction of the national score for each patient to be registered on the waiting list, the use of split grafts or grafts from marginal criteria donors may enlarge the donor pool. Liver grafts from cardiac deceased donors or from living donors are less frequent and are controversial from a technical and psychological point of view. The most efficient solution in order to overcome organ shortage is the increase in the pool of brain dead donors by accompanying people acceptance of organ donation and the use of parts of human body after death. Such education of the population could be made by the valorisation of organ donation, through public campaigns suggesting reflexion rather than coercition.

Liver transplantation is the only definitive treatment option for patients with irrevocable acute or chronic liver failure. In the last four decades, liver transplantation has developed from an experimental approach with a very high mortality to an almost routine procedure with good short- and long-term survival rates. Here, we present an up-to-date overview of the indications and contraindications for liver transplantation. It is shown how the evaluation of a candidate and finally listing for transplantation has to be performed in a multidisciplinary setting. Meticulous listing, timing, and organ allocation are the crucial factors to achieve an optimal outcome for the individual patient on the one hand, and reasonably using the limited deceased donor pool on the other hand. Living-donor liver transplantation is demanding but necessarily increasing. Because patients after liver transplantation need lifelong aftercare, it is important for primary care clinicians to understand the basic medical problems and risks. PMID:24789874

Tyrosinemia is a disease of the tyrosine metabolism, affecting mainly liver, kidney and peripheral nerves. Two forms of liver disease caused by a deficiency of FAH are recognised: (1) acute liver failure; (2) chronic liver disease. Since the introduction of NTBC [2-(2-nitro-4-trifluoromethyl benzoyl)-1-3-cyclohexanedione] (nitisinone(R)) in the treatment of tyrosinemia, no liver disease has been observed when started in the first weeks of life. Liver transplantation is a good option for the treatment of tyrosinemic patients developing liver nodules, with high suspicion of hepatocarcinoma. In the long-term outcome of the liver transplant, survival was of 90% in tyrosinemic patients.

To summarize the clinical characteristics, early diagnosis, comprehensive treatment and prognosis of 6 cases of children with post-transplantation lymphoproliferative disorder (PTLD) after liver transplantation. Data of 6 cases with PTLD seen between January 2011 and December 2013 were retrospectively analyzed. The anti-rejection drug dose adjustments, the effect of rituximab, antiviral therapy and comprehensive treatment program after surgery were explored. (1) The diagnosis of PTLD was confirmed by histologic findings. Six cases of PTLD including 3 males and 3 females were diagnosed as congenital biliary atresia and underwent split liver transplantation. The occurrence rate of PTLD was 2.9%. (2) The median time to the development of PTLD was less than 6 months. The initial symptom of PTLD in all patients was fever and clinical manifestations of PTLD were non-specific, depending on the involving organs. Five cases of PTLD developed gastrointestinal symptoms, including diarrhea, abdominal pain, and abdominal distension. One case developed respiratory symptoms, including cough and tachypnea. Three cases had lymph node involvement. In 2 cases pathophysiology involved polymorphic lymphocyte proliferation and in 4 cases B lymphocyte proliferation. (3) Two cases died, in whom EBV DNA was not detected and were diagnosed as PTLD by surgical pathology before death. Four survived cases had high EBV-DNA load and then were diagnosed as PTLD by biopsy pathology. (4) Of the 6 cases of PTLD, 2 cases died and 4 cases survived. The overall mortality was 33%. The dead cases were only treated with laparotomy because of intestinal obstruction or perforation and the survived cases were treated with tacrolimus at reduced doses or discontinuation and rituximab. In 2 cases antiviral therapy (acyclovir) was continued, including 1 cases of intestinal obstruction treated with surgical repair. All the survived patients were followed up for 4 months to 1 year and no evidence has been found

De novo cancers are a growing problem that has become one of the leading causes of late mortality after liver transplantation. The incidences and risk factors varied among literatures and fewer concerned the Eastern population. The aim of this study was to examine the incidence and clinical features of de novo cancers after liver transplantation in a single Chinese center. 569 patients who received liver transplantation and survived for more than 3 months in a single Chinese center were retrospectively reviewed. A total of 18 de novo cancers were diagnosed in 17 recipients (13 male and 4 female) after a mean of 41 ± 26 months, with an overall incidence of 3.2%, which was lower than that in Western people. Of these, 8 (3.32%) cases were from 241 recipients with malignant liver diseases before transplant, while 10 (3.05%) cases were from 328 recipients with benign diseases. The incidence rates were comparable, p = 0.86. Furthermore, 2 cases developed in 1 year, 5 cases in 3 years and 11 cases over 3 years. The most frequent cancers developed after liver transplantation were similar to those in the general Chinese population but had much higher incidence rates. Liver transplant recipients were at increased risk for developing de novo cancers. The incidence rates and pattern of de novo cancers in Chinese population are different from Western people due to racial and social factors. Pre-transplant malignant condition had no relationship to de novo cancer. Exact risk factors need further studies.

Effect of ABO-incompatible liver transplantation on patients with severe hepatitis B (SHB) remains unclear. Herein, we summarized 22 cases with SHB in whom were performed emergency liver transplantation from ABO-incompatible donors. The immunosuppressive protocol consisted basiliximab, tacrolimus, steroids and mycophenolate mofetil. The mean MELD score was 35.2 ± 7.1. Major complications included rejection, infections, biliary complications, hepatic artery thrombosis or stenosis and portal vein thrombosis. Patient survival rates were 40.9%, 78.9% and 82.3% in 1 year, 29.2%, 66.8% and 72.9% in 3 years, and 21.9%, 60.1% and 62.5% in 5 years for ABO-incompatible, ABO-compatible and ABO-identical groups. Graft survival rates were 39%, 78.9% and 82.3% in 1 year, 27.8%, 66.4% and 71.1% in 3 years, and 20.9%, 57.9% and 61.0% in 5 years for incompatible, compatible and identical ABO graft-recipient match. The 1-, 3-, 5-year graft and patient survival rates of ABO-incompatible were distinctly lower than that of ABO-compatible group (P < 0.05). Our results suggested that ABO-incompatible liver transplantation might be a life-saving procedure for patients with SHB as a promising alternative operation when ABO-compatible donors are not available and at least bridges the second opportunity for liver retransplantation.

Since the first successful liver transplantation by Starzl et al. in 1967, liver transplantation has become the standard therapy for many liver diseases, mainly chronic liver disease. Most liver transplantations performed in Europe and North America utilize deceased donors while a considerable portion of organ requirements is supplied by living donors in Asian countries including Turkey. The actual history of solid organ transplantation in Turkey began with the pioneering work of Dr. Haberal in collaboration with Thomaz E. Starzl in 1974 in Colorado University at Denver. The first successful solid organ transplantation in Turkey was accomplished by Haberal in 1975 with a living donor renal transplantation. Subsequently, legislations no 2238 and 2594 dated 1979 and 1982, respectively, were passed, paving the way for cadaveric tissue/organ utilization and preservation in Turkey. The first deceased donor liver transplantation and the first living donor liver transplantation were performed in 1988 and 1990, respectively. There are currently 45 liver transplantation centers in Turkey. Of these, 25 are state universities, 8 are private (foundation) universities, 9 are private hospitals, and 3 are training and research hospitals belonging to the Ministry of Health. A total of 7152 liver transplantations were performed in Turkey between January 2002 and May 2014. Of these, 4848 (67.8%) used living donors and 2304 (32.2%) used deceased donors. These figures indicate that, despite widespread organ donation campaigns and media-sponsored propaganda, desired targets have not been met yet in providing deceased organ donation. Despite unsatisfactory levels attained in supplying deceased donors, both the number of annual liver transplantations and improvements in overall survival rates of organ transplanted patients continues to increase. Actually, the one-year patient survival rate after liver transplantation in 2013 was 80.5%. This rate is getting better with each passing year

Hepatocellular carcinoma (HCC) is a heterogeneous malignancy with multiple etiologies, high incidence, and high mortality. The standard surgical management for patients with HCC consists of locoregional ablation, surgical resection, or liver transplantation, depending on the background state of the liver. Eighty percent of patients initially presenting with HCC are unresectable, either due to the extent of tumor or the level of underlying hepatic dysfunction. While in patients with no evidence of cirrhosis and good hepatic function resection has been the surgical treatment of choice, it is contraindicated in patients with moderate to severe cirrhosis. Liver transplantation is the optimal surgical treatment. PubMed search of recent articles (from January 2000 to March 2011) was performed looking for relevant articles about hepatocellular carcinoma and its treatment. Additional articles were identified by evaluating references from selected articles. Here we review criteria for transplantation, the types, indications, and role of locoregional therapy in treating the cancer and in downstaging for possible later transplantation. We also summarize the contribution of immunosuppression and adjuvant chemotherapy in the management and prevention of HCC recurrence. Finally we discuss recent advances in imaging, tumor biology, and genomics as we delineate the remaining challenges for the diagnosis and treatment of this disease. Much can be improved in the diagnosis and treatment of HCC. A great challenge will be to improve patient selection to criteria based on tumor biology. Another will be to incorporate systemic agents post-operatively in patients at high risk for recurrence, paying close attention to efficacy and safety. The future direction of the effort in treating HCC will be to stimulate prospective trials, develop molecular imaging of lymphovascular invasion, to improve recipient selection, and to investigate biomarkers of tumor biology.

Spain is one of the countries where most solid organ transplants are performed each year, in the year 2014 a 2.7% of them were given in childhood. Given the complexity and severity of this disease it is necessary to establish a care plan that covers both pre-transplant and post-transplant, with close cooperation between different levels of care, to approach the several problems that can appear and assure continuum of care. In the following example, a Gambian teen with risk of social exclusion fostered a collaboration between the primary care nurse and transplant nurse that was the key to continuum care. Multiple strategies were used in the care plan to ensure better adherence and compliance of the treatment. However, the knowledge of the culture of origin must be deepened to establish more individualized care plans and thus improve results. The care plan included problems according to the NANDA, NOC, NIC taxonomy.

Liver transplantation is the most extreme form of surgical management of patients with hepatic trauma, with very limited literature data supporting its use. The aim of this study was to assess the results of liver transplantation for hepatic trauma. This retrospective analysis based on European Liver Transplant Registry comprised data of 73 recipients of liver transplantation for hepatic trauma performed in 37 centers in the period between 1987 and 2013. Mortality and graft loss rates at 90 days were set as primary and secondary outcome measures, respectively. Mortality and graft loss rates at 90 days were 42.5% and 46.6%, respectively. Regarding general variables, cross-clamping without extracorporeal veno-venous bypass was the only independent risk factor for both mortality (P = 0.031) and graft loss (P = 0.034). Regarding more detailed factors, grade of liver trauma exceeding IV increased the risk of mortality (P = 0.005) and graft loss (P = 0.018). Moreover, a tendency above the level of significance was observed for the negative impact of injury severity score (ISS) on mortality (P = 0.071). The optimal cut-off for ISS was 33, with sensitivity of 60.0%, specificity of 80.0%, positive predictive value of 75.0%, and negative predictive value of 66.7%. Liver transplantation seems to be justified in selected patients with otherwise fatal severe liver injuries, particularly in whom cross-clamping without extracorporeal bypass can be omitted. The ISS cutoff less than 33 may be useful in the selection process.

Survival in cystic fibrosis patients after liver transplantation and liver-lung transplantation is not well studied. To discern survival rates after liver transplantation and liver-lung transplantation in patients with and without cystic fibrosis. The United Network for Organ Sharing database was queried from 1987 to 2013. Univariate Cox proportional hazards, multivariate Cox models, and propensity score matching were performed. Liver transplant and liver-lung transplant were performed in 212 and 53 patients with cystic fibrosis, respectively. Univariate Cox proportional hazards regression identified lower survival in cystic fibrosis after liver transplant compared to a reference non-cystic fibrosis liver transplant cohort (HR 1.248; 95 % CI 1.012, 1.541; p = 0.039). Supplementary analysis found graft survival was similar across the 3 recipient categories (log-rank test: χ(2) 2.68; p = 0.262). Multivariate Cox models identified increased mortality hazard among cystic fibrosis patients undergoing liver transplantation (HR 2.439; 95 % CI 1.709, 3.482; p < 0.001) and liver-lung transplantation (HR 2.753; 95 % CI 1.560, 4.861; p < 0.001). Propensity score matching of cystic fibrosis patients undergoing liver transplantation to non-cystic fibrosis controls identified a greater mortality hazard in the cystic fibrosis cohort using a Cox proportional hazards model stratified on matched pairs (HR 3.167; 95 % CI 1.265, 7.929, p = 0.014). Liver transplantation in cystic fibrosis is associated with poorer long-term patient survival compared to non-cystic fibrosis patients, although the difference is not due to graft survival.

Combined en bloc liver/pancreas transplantation (CLPT) was used primarily in the treatment of otherwise non-resectable upper abdominal malignancy. In fact, a more appropriate indication is in patients with liver disease and insulin-dependent diabetes mellitus (IDDM). Here, we report on two successful cases of CLPT at our hospital. One was a patient with non-resectable advanced liver cancer. The recipient survived for 23 mo and finally died of recurrent tumor. The other was a patient with severe biliary complication after orthotopic liver transplantation and preoperative IDDM. We performed CLPT with a modified surgical technique of preserving the native pancreas. He is currently liver-disease- and insulin-free more than 27 mo post-transplant. Based on our experience in two cases of abdominal cluster transplantation, we describe the technical details of CLPT and a modification of the surgical procedure. PMID:19469010

The infrequent occurrence of herpes simplex virus (HSV) hepatitis in healthy women in comparison with the high prevalence of HSV infections suggests that, in addition to deranged immunity, an underlying condition in the liver might be necessary to develop HSV hepatitis. We report the case of a 28-year-old pregnant woman in the 28 (th) week of gestation. Following HSV type 2 infection of the uterine cervix, acute liver failure developed, necessitating urgent liver transplantation. In addition to fulminant HSV type 2 hepatitis, the explanted liver also showed the histological features of acute fatty liver of pregnancy. The presented case suggests a possible pathogenetic role of acute fatty liver of pregnancy in the development of fulminant HSV hepatitis following recurrent infection with HSV in healthy pregnant women. We believe that early histopathological diagnosis, followed by specific antiviral treatment and liver transplantation in selected patients may improve the clinical outcome of otherwise almost uniformly fatal HSV hepatitis.

Organ shortage is responsible for high mortality rates of patients awaiting liver transplantation (LT). Domino transplantation has had reported success in patients with metabolic disorders. Primary hyperoxaluria type 1 (PH1) is a rare metabolic disorder. There are a few case reports that suggest that PH1 livers originating from donors that have undergone combined liver-kidney transplantation can be successfully used for domino transplantation. In the last decade, five patients received a domino liver transplant from patients with PH1 in the EUROTRANSPLANT region. In this study, we report the clinical course and outcome of these five patients who were received a domino graft transplant. All patients, with the exception of one, suffered from multifocal hepatocellular carcinoma and underwent domino LT from patients undergoing combined liver-kidney transplantation for PH1. Within the first 4 weeks, all the domino recipients developed dialysis-dependent kidney failure despite good liver function. Four of the five patients died. The only survivor underwent retransplantation due to hepatic artery thrombosis. Twenty months after transplantation, this patient is doing well and has had no recurrence of hepatocellular carcinoma. Domino LT using donors with PH1 results in early renal failure and cannot be recommended for transplantation unless preventive strategies have been identified.

Background Hepatopulmonary syndrome is formed by a triad of liver disease, intrapulmonary vascular dilatation and changes in blood gases. This condition is present in 4-32% of patients with cirrhosis. Aim To analyze the blood gas changes data of patients in liver-transplant waiting list. Method Clinical data of 279 patients in liver transplantation waiting list in May 2013 were studied. Overall patient was analyzed by the demographic aspects, laboratorial and image findings on exams that determine lung disease (hypoxemia) in these cirrhotic patients. The mean values and standard deviations were used to examine normally distributed variables. Results There was a high prevalence of male patients (68%); the mean age was 51(±5,89) years, and the predominant reason for listing was hepatitis C cirrhosis. The MELD score mean was 16±5,89, without prioritization or special situation. The most common blood type was O in 129 cases (46%) and the mean of body max index was 25,94±4,58. Regarding arterial blood gas tests was observed 214 patients with PaO2 <90 mmHg, 80 with PaO2 <80 mmHg and 39 with PaO2 <50 mmHg. In relation to O2 saturation, 50 patients had <90%, 33 <80% and 10 <50%. Conclusion Was observed a high rate of hypoxemia in patients on waiting list liver transplant. Due to the high severity and morbidity, is suggested better monitoring and therapeutic support to hypoxemic patients on liver transplant waiting list. PMID:24676301

Because of a shortage of organs, non-heart-beating donors have been proposed to be a possible source of grafts for orthotopic liver transplantation. Herein, we have presented a blood group A+ patient with primary biliary cirrhosis, who underwent orthotopic liver transplantation from a non-heart-beating blood group A- donor. On day 5 after transplantation the patient displayed a low hemoglobin levels as well as an increased total bilirubin with progressive encephalopathy, hypotension, and oligoanuria on day 11. The patient responded to steroid treatment. We assume the main cause of organ dysfunction was a passenger lymphocyte syndrome (ABO-Rh incompatibility). Biliary complications were detected at a 6-month follow-up visit by increased hepatic enzymes. We thus concluded that it is useful to take Rh group into account.

Anesthesia for liver transplantation (ALT) requires extensive preparation and rapid recognition of changing clinical conditions. Owing to the proliferation of transplant centers, greater number of anesthesia providers need training in specific skills required to treat these patients. These cases are no longer limited to few transplant centers; therefore, reduction of cases in individual centers has created a need for simulation training to prepare and supplement clinical experience. We have developed an ALT simulation course for senior anesthesia residents which combines didactic sessions with live-patient-based and mannequin-based simulation. Outcomes have been measured using pre- and post-simulation course quizzes as well as a survey given at the end of the month-long ALT rotation. Twenty-four senior anesthesiology residents (n = 24) have completed the ALT simulation course. Residents had an average score of 75% ± 10% on the pre-simulation quiz, which increased to 92% ± 6.5% on the post-simulation quiz (p < 0.001). Furthermore, survey scores indicated that residents noted that the course provided an improvement in their preparedness, confidence, anticipation, and understanding of the importance of communication skills in the care of this patient population. The ALT simulation course provided a standardized in-depth exposure to clinical issues involved in the perioperative care of liver transplant patients.

Since January 1994, we have used percutaneous placement of both the subclavian and femoral cannulae to establish access for venovenous bypass during orthotopic liver transplantation. Percutaneous subclavian and femoral cannulae were used in 36 patients of which 5 had portal decompression by placement of a cannula in inferior mesenteric vein percutaneously through the abdominal wall. Intraoperative placement of the subclavian cannula is facilitated by placing a subclavian central venous line before the abdominal incision. One patient underwent exploration for femoral vein bleeding early in our experience. Another patient sustained hypotension as a result of a kinked subclavian cannula. In 4 patients, early in this experience, we had difficulty placing the subclavian cannula and resorted to axillary vein cut-down. There were no episodes of deep venous thrombosis detected by routine postoperative duplex ultrasonography. Minimum and maximum flow rates were significantly better (P < .01), with percutaneously placed cannulae in comparison to a control group of patients who underwent transplantation in whom we used the standard venous cut-down approach with a #7 Gott shunt (2.14 and 3.17 L/min v 1.65 and 2.41 L/min, respectively). Percutaneous placement of cannulae for venovenous bypass during liver transplantation is quick, safe, and effective. We would advocate this technique as an alternative approach for patients in whom bypass is deemed necessary.

Fibrolamellar hepatocellular carcinoma is a rare hepatocellular tumor usually arising in noninfected and noncirrhotic livers. Only 2 cases accompanied by hyperammonemia due to intrahepatic shunting have been reported. A 23-year-old white woman presented with a 2-week history of nausea, vomiting, generalized weakness, and intermittent right upper quadrant pain. Abdominal computerized tomography revealed a 13 x 9-cm hepatic mass. Core-needle biopsy revealed fibrolamellar hepatocellular carcinoma. She presented with coma due to hyperammonemia levels (peak at 437 mcg/dL) but without metastatic disease. She was urgently transplanted, started on daily sorafenib 8 weeks after transplantation, and was free of disease at 1 year after transplantation. PMID:27807568

Biliary strictures are the most common biliary tract complication after liver transplantation. There are scarce data on the results of hepaticojejunostomy (HJ) in the management of biliary complications after orthotopic liver transplantation (OLT). Thus, the role of surgery in this setting remains to be established. The aim of this study was to evaluate the results of surgical treatment of patients with biliary complications at our institution. We reviewed 1000 consecutive liver transplantations performed at our institution from 1984 to 2007. We used a prospectively recorded database to identify patients who underwent HJ to treat any biliary tract complication. Overall, 62 patients (6.2%) underwent HJ, 40 for an anastomotic and 7 for a non-anastomotic stricture as well as 15 for biliary leaks. Postoperative morbidity was 16%, and postoperative mortality 1.6%. There were 7 cases of anastomotic stenosis (11.3%). Four patients (5%) required retransplantation. HJ is a safe procedure to manage biliary complications after OLT. It may be the first treatment choice especially for cases with anastomotic strictures. Copyright © 2012 Elsevier Inc.

Several methods have been proposed to assess causality in drug-induced liver injury but none have been tested in the specific context of acute liver failure leading to transplantation (ALFT). We took advantage of the Study of Acute Liver Transplant (SALT), a European case-population study of ALFT, to test different causality scales. Causality was assessed by experts in SALT, a 7-country case-population study from 2005 to 2007 of adult otherwise unexplained ALFT, for all drugs found within 30 days prior to the date of initial symptoms of liver disease (index date), using information content, causality scales, and data circuit determined from a pilot study, Salome. The consensus points from Salome were to provide full data on drugs including international non-proprietary name (INN) and doses except for non-steroidal anti-inflammatory drugs (NSAIDs) and to use the World Health Organization (WHO) causality scale. In SALT, among the 9,479 identified patients, 600 (6.3%) were cases of ALFT, of which 187 had been exposed to drugs within 30 days, without overdose. In 130 (69.5%) of these the causality score was possible, probable, or highly probable. In ALFT cases, once other clinical causes have been excluded and drug exposure established within 30 days, the main discriminant characteristic for causality will be previous knowledge of possible hepatotoxicity.

Chronic hepatitis B virus (HBV) infection is responsible for up to 30% of cases of liver cirrhosis and up to 53% of cases of hepatocellular carcinoma. Liver transplantation (LT) is the best therapeutic option for patients with end-stage liver failure caused by HBV. The success of transplantation, though, depends on receiving prophylactic treatment against post-transplant viral reactivation. In the absence of prophylaxis, liver transplantation due to chronic hepatitis B (CHB) is associated with high rates of viral recurrence and poor survival. The introduction of treatment with hepatitis B immunoglobulins (HBIG) during the 1990s and later the incorporation of oral antiviral drugs have improved the prognosis of these patients. Thus, LT for CHB is now a universally accepted option, with an estimated 5 years survival of around 85% vs the 45% survival seen prior to the introduction of HBIG. The combination of lamivudine plus HBIG has for many years been the most widely used prophylactic regimen. However, with the appearance of new more potent oral antiviral agents associated with less resistance (e.g., entecavir and tenofovir) for the treatment of CHB, new prophylactic strategies are being designed, either in combination with HBIG or alone as a monotherapy. These advances have allowed for more personalized prophylaxis based on the individual risk profile of a given patient. In addition, the small pool of donors has required the use of anti-HBc-positive donors (with the resulting possibility of transmitting HBV from these organs), which has been made possible by suitable prophylactic regimens.

Acute liver failure (ALF) in children is a rare but often fatal event. At present, liver transplantation is the only successful therapy in most cases. In the face of deteriorating hepatic encephalopathy in these children, some bridging therapy using artificial detoxification can be necessary to enable successful transplantation. In adults, albumin dialysis using the molecular absorbent recycling system (MARS) has been described as effective for bridging to liver transplantation. A previously healthy 7-month-old infant was admitted with ALF due to autoimmune hepatitis. King's College criteria for children with ALF indicated the need for transplantation (bilirubin 13.7 mg/dl, leukocytes 18,980/mm3, INR 5.83, age<2 years). Despite moderate hyperammonemia (75 microm/l) along with the development of pneumonia, the child deteriorated hemodynamically and neurologically, showing grade III encephalopathy proven by EEG. Albumin dialysis using MARS was used to bridge 36 hours to successful living-donor split-liver transplantation, and resulted in improvements in EEG, plasma levels of amino acids and hemodynamics. Twenty-four months after transplantation the child shows normal liver function and normal neuropsychological development. The explanted liver showed 80 % tissue destruction from autoimmune hepatitis. Albumin dialysis as described can be used successfully in infants < 1 year old for bridging to liver transplantation in cases of acute hepatic failure with deteriorating encephalopathy.

Porphyrias are a group of eight metabolic disorders, each resulting from a mutation that affects an enzyme of the heme biosynthetic pathway. Porphyrias are classified as hepatic or erythropoietic, depending upon the site where the gene defect is predominantly expressed. Clinical phenotypes are classified as follows: (1) acute porphyrias with neurovisceral symptoms: acute intermittent porphyria; delta amino-levulinic acid hydratase deficiency porphyria; hereditary coproporphyria; and variegate porphyria and (2) cutaneous porphyrias with skin blistering and photosensitivity: porphyria cutanea tarda; congenital erythropoietic porphyria; hepatoerythropoietic porphyria and both erythropoietic protoporphyrias: autosomal dominant and X-linked. Liver transplantation (LT) may be needed for recurrent and/or life-threatening acute attack in acute intermittent porphyria or acute liver failure or end-stage chronic liver disease in erythropoietic protoporphyria. LT in acute intermittent porphyria is curative. Erythropoietic protoporphyria patients needing LT should be considered for bone marrow transplantation to achieve cure. Conclusion This article provides an overview of porphyria with diagnostic approaches and management strategies for specific porphyrias and recommendations for LT with indications, pretransplant evaluation, and posttransplant management.

The poor clinical conditions associated with end-stage cirrhosis, pre-existing pulmonary abnormalities, and high comorbidity rates in patients with high Model for End-Stage Liver Disease scores are all well-recognized factors that increase the risk of pulmonary complications after orthotopic liver transplantation (OLT) surgery. Many intraoperative and postoperative events, such as fluid overload, massive transfusion of blood products, hemodynamic instability, unexpected coagulation abnormalities, renal dysfunction, and serious adverse effects of reperfusion syndrome, are other factors that predispose an individual to postoperative respiratory disorders. Despite advances in surgical techniques and anesthesiological management, the lung may still suffer throughout the perioperative period from various types of injury and ventilatory impairment, with different clinical outcomes. Pulmonary complications after OLT can be classified as infectious or non-infectious. Pleural effusion, atelectasis, pulmonary edema, respiratory distress syndrome, and pneumonia may contribute considerably to early morbidity and mortality in liver transplant patients. It is of paramount importance to accurately identify lung disorders because infectious pulmonary complications warrant speedy and aggressive treatment to prevent diffuse lung injury and the risk of evolution into multisystem organ failure. This review discusses the most common perioperative factors that predispose an individual to postoperative pulmonary complications and these complications' early clinical manifestations after OLT and influence on patient outcome.

It is critical to balance waitlist mortality against posttransplant mortality. Our objective was to devise a scoring system that predicts recipient survival at 3 months following liver transplantation to complement MELD-predicted waitlist mortality. Univariate and multivariate analysis on 21,673 liver transplant recipients identified independent recipient and donor risk factors for posttransplant mortality. A retrospective analysis conducted on 30,321 waitlisted candidates reevaluated the predictive ability of the Model for End-Stage Liver Disease (MELD) score. We identified 13 recipient factors, 4 donor factors and 2 operative factors (warm and cold ischemia) as significant predictors of recipient mortality following liver transplantation at 3 months. The Survival Outcomes Following Liver Transplant (SOFT) Score utilized 18 risk factors (excluding warm ischemia) to successfully predict 3-month recipient survival following liver transplantation. This analysis represents a study of waitlisted candidates and transplant recipients of liver allografts after the MELD score was implemented. Unlike MELD, the SOFT score can accurately predict 3-month survival following liver transplantation. The most significant risk factors were previous transplantation and life support pretransplant. The SOFT score can help clinicians determine in real time which candidates should be transplanted with which allografts. Combined with MELD, SOFT can better quantify survival benefit for individual transplant procedures.

Case series Patient: Male, 38 • Male, 48 Final Diagnosis: En-bloc transplantation (liver, kidney, pancreas) Symptoms: Encephalopathy • adynamia • ascites • asthenia Medication: — Clinical Procedure: En-bloc transplantation Specialty: Transplantology Objective: Unusual setting of medical care Background: En-bloc transplantation is a surgical procedure in which multiple organs are transplanted simultaneously. It has some similarities with multi-organ transplantation but offers certain advantages. This report highlights the experience of our interdisciplinary group regarding the treatment and follow-up of patients who received en-bloc transplantation, with the aim of encouraging the development of this surgical technique. Case Report: The first case is a 38-year-old patient with type 1 diabetes mellitus, liver cirrhosis, and chronic kidney failure who received an en-bloc transplant of the liver, pancreas, and kidney with no intraoperative complications. He had a prolonged hospital stay due to anemia and systemic inflammatory response syndrome, which were resolved successfully. At follow-up, he had no requirement for insulin or for dialysis, or for new interventions. The second case describes a 48-year-old patient with type 2 diabetes mellitus, renal failure, and liver cirrhosis who received an en-bloc transplant of the liver, pancreas, and kidney with no complications. During the postoperative period, the patient suffered a possible episode of acute tubular necrosis, which evolved towards improvement, with a tendency to normal metabolic and renal functioning, with no additional events. The patient is currently in follow-up and is insulin-independent. Conclusions: En-bloc transplantation is a safe procedure, which is technically simple and which achieves excellent results. This procedure is indicated in patients with end-stage renal disease, cirrhosis, and diabetes mellitus that is difficult to control. PMID:28148909

Hereditary transthyretin amyloidosis (ATTR) is a rare worldwide autosomal dominant disease caused by the systemic deposition of an amyloidogenic variant of transthyretin (TTR), which is usually derived from a single amino acid substitution in the TTR gene. More than 100 mutations have been described, with V30M being the most prevalent. Each variant has a different involvement, although peripheral neuropathy and cardiomyopathy are the most common. Orthotopic liver transplantation (OLT) was implemented as the inaugural disease-modifying therapy because the liver produces the circulating unstable TTR. In this review, we focus on the results and long-term outcomes of OLT for ATTR after more than 2063 procedures and 23 years of experience. After successful OLT, neuropathy and organ impairment are not usually reversed, and in some cases, the disease progresses. The overall 5-year survival rate is approximately 100% for V30M patients and 59% for non-ATTR V30M patients. Cardiac-related death and septicemia are the main causes of mortality. Lower survival is related to malnutrition, a longer duration of disease, cardiomyopathy, and a later onset (particularly for males). Deposits, which are composed of a mixture of truncated and full-length TTR (type A) fibrils, have been associated with posttransplant myocardial dysfunction. A higher incidence of early hepatic artery thrombosis of the graft has also been documented for these patients. Liver-kidney/heart transplantation is an alternative for patients with advanced renal disease or heart failure. The sequential procedure, in which ATTR livers are reused in patients with liver disease, reveals that neuropathy in the recipient may appear as soon as 6 years after OLT, and ATTR deposits may appear even earlier. Long-term results of trials with amyloid protein stabilizers or disrupters, silencing RNA, and antisense oligonucleotides will highlight the value and limitations of liver transplantation.

Liver transplantation originated in children more than 50 years ago, and these youngest patients, while comprising the minority of liver transplant recipients nationwide, can have some of the best and most rewarding outcomes. The indications for liver transplantation in children are generally more diverse than those seen in adult patients. This diversity in underlying cause of disease brings with it increased complexity for all who care for these patients. Children, still being completely dependent on others for survival, also require a care team that is able and ready to work with parents and family in addition to the patient at the center of the process. In this review, we aim to discuss diagnoses of particular uniqueness or importance to pediatric liver transplantation. We also discuss the evaluation of a pediatric patient for liver transplant, the system for allocating them a new liver, and also touch on postoperative concerns that are unique to the pediatric population.

Liver transplantation (LT) represents the only chance of long-term survival for patients with end-stage liver disease. When the mortality rate for transplant patients returns to the same level as that for the general population, they can be considered statistically cured. However, cure models in the setting of LT have never been applied. Data from 1371 adult patients undergoing LT for the first time between January 1999 and December 2012 at 2 Italian centers were reviewed in order to establish probabilities of being cured by LT. A parametric Weibull model was applied to compare the mortality rate after LT to the rate expected for the general population (matched by sex and age). The observed 3-, 5-, and 10-year overall survival rates after LT were 77.8%, 73.3%, and 65.6%, respectively, and they did not differ between the 2 centers (P = 0.37). The cure fraction for the entire study population was 63.4% (95% confidence interval = 52.6%-72.0%), and the time to cure was 10 years with a 90% confidence level. The best cure fraction was observed for younger recipients without hepatitis C virus (HCV) who had favorable donor-recipient matches, that is, low Donor Model for End-Stage Liver Disease (D-MELD) scores (90.1%); conversely, the lowest probability was observed for elderly HCV recipients with high D-MELD scores (34.6%). The time to cure was 6.22 years for non-HCV patients and 14.78 years for HCV patients. The median survival time for uncured patients was 2.29 years. Among uncured recipients, the longest survival time was observed for younger patients (7.31 years). In conclusion, we provide here a new clinical measure for LT suggesting that survival after transplantation can approximate that of the general population and provide a statistical cure.

We report the case of a 62-year-old man hospitalized in May 2015 for symptomatic heart failure. His medical history included two liver transplantations. The first liver transplantation was performed in 1999 for a mixed alcoholic and hepatitis C-related cirrhosis and the patient received the liver of another patient with Val30Met transthyretin amyloidosis using the domino technique. In 2008, he complained of neuropathic pains and an iatrogenic-acquired transthyretin amyloidosis was diagnosed. On cardiac evaluation, amyloidosis was suspected. In March 2010, a second liver transplantation was performed with a deceased donor without complication. In May 2015, a first episode of symptomatic heart failure occurred and cardiac amyloidosis was investigated by a multimodality evaluation. Electrocardiogram, cardiac biomarkers, echocardiography, and cardiac MRI were in favor of the diagnosis of amyloidosis, whereas (99m) Tc-dicarboxypropane diphosphonate scintigraphy was not. Endomyocardial biopsy finally confirmed the positive diagnosis of iatrogenic-acquired cardiac amyloidosis. This case is, to the best of our knowledge, the first to report biopsy-proven cardiac amyloidosis induced by domino liver transplantation and progressing heart failure in spite of retransplantation. The diagnostic modalities are discussed. This case should alert physicians to the cardiac risk in domino liver transplanted patients. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

Portal vein thrombosis (PVT) is a frequent finding in liver transplantation, the management of which depends mainly on its extent. In cases of mild to moderate PVT, a low dissection of the portal trunk, a jump graft, or direct implantation of graft portal vein into large venous collaterals or thrombectomy offer alternatives. For severe PVT anecdotal reports suggest that cavoportal hemitransposition, portal arterialization, or combined liver and intestine transplantation may be attempted, although the results to date are not satisfactory. When extensive perivenous and venous inflammatory changes reach the infrapancreatic region, liver transplantation probably should not be performed due to the high mortality rate.

Background Liver transplantation is performed at large transplant centers worldwide as a therapeutic intervention for patients with end-stage liver diseases. Aim To analyze the outcomes and incidence of liver transplantation performed at the University of São Paulo and to compare those with the State of São Paulo before and after adoption of the Model for End-Stage Liver Disease (MELD) score. Method Evaluation of the number of liver transplantations before and after adoption of the MELD score. Mean values and standard deviations were used to analyze normally distributed variables. The incidence results were compared with those of the State of São Paulo. Results There was a high prevalence of male patients, with a predominance of middle-aged. The main indication for liver transplantation was hepatitis C cirrhosis. The mean and median survival rates and overall survival over ten and five years were similar between the groups (p>0.05). The MELD score increased over the course of the study period for patients who underwent liver transplantation (p>0.05). There were an increased number of liver transplants after adoption of the MELD score at this institution and in the State of São Paulo (p<0.001). Conclusion The adoption of the MELD score led to increase the number of liver transplants performed in São Paulo. PMID:25184772
Liver transplantation is one of the most spectacular of surgical achievements. It is a demanding and expensive procedure, requiring great surgical skill and a great depth of supporting services. Precisely because it is a procedure at the leading edge of medicine, more and more units in developed countries are pressing to be allowed to carry it out. But there are many moral and ethical problems, some of which can be usefully examined using a “Mozart model” as proposed by Starzl. PMID:2282327

A reproducible and transparent quality of clinical treatments plays an important role in the performance of a hospital. In liver transplantation (LT), this is particularly important for patient safety, resource planning, documentation, and quality management. Thus, the clinical pathway for LT was documented in an electronic format within our research project PIGE. Data from clinical information systems were linked to this pathway, which allows for process monitoring (the assessment of the current state for every patient in the LT process) and a retrospective analysis of all treatments in addition to all data pertaining to the treatment, for example, cost, time, number of personnel, etc.

AIM To investigate incidence and survival of post-transplant lymphoproliferative disorder (PTLD) patients after liver transplantation. METHODS A cross-sectional survey was conducted among patients who underwent liver transplantation at Shiraz Transplant Center (Shiraz, Iran) between August 2004 and March 2015. Clinical and laboratory data of patients were collected using a data gathering form. RESULTS There were 40 cases of PTLD in the pediatric age group and 13 cases in the adult group. The incidence of PTLD was 6.25% in pediatric patients and 1.18% in adult liver transplant recipients. The post-PTLD survival of patients at 6 mo was 75.1% ± 6%, at 1 year was 68.9% ± 6.5% and at 5 years was 39.2% ± 14.2%. Higher serum tacrolimus level was associated with lower post-PTLD survival in pediatric patients (OR = 1.07, 95%CI: 1.006-1.15, P = 0.032). A serum tacrolimus level over 11.1 ng/mL was predictive of post PTLD survival (sensitivity = 90%, specificity = 52%, area under the curve = 0.738, P = 0.035). CONCLUSION Incidence of PTLD in our liver transplant patients is comparable to other centers. Transplant physicians may consider adjustment of tacrolimus dose to maintain its serum level below this cutoff point. PMID:28275302

Because right-lobe living-donor liver transplantation was introduced in adult-to-adult liver transplantation to mitigate the problems of small-for-size grafts, some technical controversies have been reported. This report describes a case of graft subcapsular hematoma due to parenchymal injury. A 53-year-old woman underwent a right-lobe living-donor liver transplantation for acute-on-chronic liver failure due to primary biliary cirrhosis. A huge subcapsular hematoma was discovered by routine Doppler echogram examination on the first posttransplantation day. Relaparotomy findings revealed that rotation of the graft for the hemostasis procedure during the transplant operation had induced a compression injury to the graft by the xiphoid process. It was speculated that a small laceration in the graft parenchyma led to the major subcapsular hematoma. This experience suggests that the graft liver must be handled with special care to prevent potential mechanical injury.

BACKGROUND: Ischemic cardiac events can cause significant morbidity and mortality postliver transplantation; however, no validated protocols to screen patients before transplantation exist. OBJECTIVES: To report the introduction of a noninvasive cardiac screening protocol used at the Liver Unit, University of Calgary (Calgary, Alberta); to determine whether the protocol decreases use of coronary angiograms; and to compare cardiac outcomes using the new protocol with an appropriately matched historical control group. METHODS: A new cardiac screening protocol was introduced into the program in 2005, which uses perfusion scintigraphy to screen high-risk cardiac patients, reserving coronary angiograms for abnormal results. Transplanted patients screened using this protocol were compared with matched historical controls. Electronic charts were reviewed for cardiac outcomes intra- and postliver transplantation. RESULTS: A total of 396 patients were screened between April 2005 and February 2009. Eighty-two were transplanted by February 2009 and included in the study. Eighty-one patients were successfully matched according to age, sex, cardiac history and presence of diabetes. Twelve of 82 (14.6%) and 11 of 81 (13.6%) in the study and control groups, respectively, underwent coronary angiograms (P=0.85). Coronary artery disease was found in six of 12 (50.0%) study patients and three of 11 (27.3%) control patients who underwent coronary angiography (P=0.27). The mean (± SD) length of the follow-up period was 1.87±0.91 years and 4.45±1.89 years in the study and control groups, respectively. One of 81 in the control group and zero of 82 in the study group experienced an acute coronary syndrome event postoperatively. CONCLUSIONS: Coronary events are infrequent in liver transplant recipients. The described protocol is an effective method of coronary artery disease screening before liver transplant but does not reduce the number of cardiac investigations performed. PMID

Chronic hepatitis C virus (HCV) infection is the leading cause of death from liver disease and the leading indication for liver transplantation (LT) in the United States and Western Europe. LT represents the best therapeutic alternative for patients with advanced chronic liver disease caused by HCV or those who develop hepatocarcinoma. Reinfection by HCV of the graft is universal and occurs in 95% of transplant patients. This reinfection can compromise graft function and patient survival. In a few cases, the histological recurrence is minimal and non-progressive; however, in most patients it follows a more rapid course than in immunocompetent persons, and frequently evolves into cirrhosis with graft loss. In fact, the five-year and ten-year survival of patients transplanted because of HCV are 75% and 68%, respectively, compared with 85% and 78% in patients transplanted for other reasons. There is also a pattern of recurrence that is very severe, but rare (< 10%), called fibrosing cholestatic hepatitis, which often involves rapid graft loss. Patients who present a negative HCV viremia after antiviral treatment have better survival. Many studies published over recent years have shown that antiviral treatment of post-transplant HCV hepatitis carried out during the late phase is the best option for improving the prognosis of these patients. Until 2011, PEGylated interferon plus ribavirin was the standard of care, resulting in a sustained virological response in around 30% of recipients. The addition of protease inhibitors, such as boceprevir or telaprevir, to the standard of care, or the use of other direct-acting antiviral drugs may involve therapeutic changes in the context of HCV recurrence. This may result a better prognosis for these patients, particularly those with severe recurrence or factors predicting rapid progression of fibrosis. However, the use of these agents in LT still requires clarification in terms of safety and efficacy. PMID:25469009

An 11-year-old boy with irreversible intestinal failure secondary to chronic intestinal pseudo-obstruction (CIPO) and intestinal failure-associated liver disease (IFALD) underwent a combined en bloc reduced liver and small bowel transplantation. He was discharged home after 9 weeks on full oral intake without requiring intravenous nutritional or fluid supplementation. The first episode of mild acute rejection, which occurred 18 months after transplantation, was successfully treated with steroids. An episode of rotavirus gastroenteritis led to severe exfoliative rejection of the bowel graft, which was resistant to steroid and Infliximab treatment but responded to OKT3. There was associated Epstein-Barr virus viremia with no evidence of posttransplant lymphoproliferative disease. Another episode of moderate to severe acute liver rejection occurred 5 months later. At the same time, multiple biliary strictures were diagnosed and treated. Persistent clinical symptoms of abdominal pain and increased stomal output as well as atrophy of the ileal mucosa on several biopsies, suggested the possibility of chronic rejection (CR). A second combined whole liver and small bowel transplant was performed. The diagnosis of CR was confirmed on histology of the explanted graft. The postoperative course was severely complicated and 71 days after the retransplantation, the boy died because of respiratory failure and multiorgan failure. In summary, intestinal transplantation can be successfully performed in children with CIPO, giving them the opportunity to be free from total parenteral nutrition. As survival following intestinal transplantation continues to improve, the problem of CR has become increasingly important and the only treatment available is retransplantation, which is associated with poor outcomes.
Liver transplantation (LT) for hepatocellular carcinoma (HCC) at Kaohsiung Chang Gung Memorial Hospital mainly relies on live donor LT (LDLT). Owing to taking the risk of LD, we are obligated to adopt strict selection criteria for HCC patients and optimize the pre-transplant conditions to ensure a high disease-free survival similar to those without HCC, even better than deceased donor LT (DDLT). Better outcomes are attributed to excellent surgical results and optimal patient selection. The hospital mortality of primary and salvage LDLT are lower than 2% in our center. Although Taiwan Health Insurance Policy extended the Milan to University of California, San Francisco (UCSF) criteria in 2006, selection criteria will not be consolidated to take into account only by the morphologic size/number of tumors but also by their biology. The criteria are divided into modifiable image morphology, alpha fetoprotein (AFP), and positron emission tomography (PET) scan with standard uptake value (SUV) and unmodifiable unfavorable pathology such as HCC combined with cholangiocarcinoma (CC), sarcomatoid type, and poor differentiation. Downstaging therapy is necessary for HCC patients beyond criteria to fit all modifiable standards. The upper limit of downstaging treatment seems to be extended by more effective drug eluting transarterial chemoembolization in cases without absolute contraindications. In contrast, the pitfall of unmodifiable tumor pathology should be excluded by the findings of pretransplant core biopsy/resection if possible. More recently, achieving complete tumor necrosis in explanted liver could almost predict no recurrence after transplant. Necrotizing therapy is advised if possible before transplant even the tumor status within criteria to minimize the possibility of tumor recurrence. LDLT with low surgical mortality in experienced centers provides the opportunities of optimizing the pre-transplant tumor conditions and timing of transplant to achieve better

Objectives To examine the techniques and the outcome of liver transplantation with maximal conservation of blood products and to analyze the potential benefits or drawbacks of blood conservation and salvage techniques. Design Case series survey. Setting Tertiary care, major university teaching hospital. Patients and Methods Four patients with religious objections to blood transfusions who were selected on the basis of restrictive criteria that would lower their risk for fatal hemorrhage, including coagulopathy, a thrombosed splanchnic venous system requiring extensive reconstruction, active bleeding, and associated medical complications. All patients were pretreated with erythropoietin to increase production of red blood cells. All operations were performed at the same institution, with a 36-month follow-up. Interventions Orthotopic liver transplantation that used blood salvage, plateletpheresis, and autotransfusion and the withholding of the use of human blood products with the exception of albumin. Main Outcome Measures Survival and postoperative complications, with the effectiveness of erythropoietin and plateletpheresis as secondary measures. Results All patients are alive at 36 months after orthotopic liver transplantation. One patient, a minor (13 years of age), was transfused per a state court ruling. Erythropoietin increased the production of red blood cells as shown by a mean increase in hematocrit levels of 0.08. Plateletpheresis allowed autologous, platelet-rich plasma to be available for use after allograft reperfusion. Three major complications were resolved or corrected without sequelae. Only one patient developed postoperative hemorrhage, which was corrected surgically. The mean charge for bloodless surgery was $174 000 for the three patients with United Network for Organ Sharing (UNOS) status 3 priority for transplantation. This result was statistically significant when these patients were compared with all the patients with UNOS status 3 priority

Liver transplantation has been remarkably effective in the treatment in patients with end-stage liver disease. However, disparity between solid-organ supply and increased demand is the greatest limitation, resulting in longer waiting times and increase in mortality of transplant recipients. This situation creates the need to seek alternatives to orthotopic liver transplantation.Hepatocyte transplantation or liver cell transplantation has been proposed as the best method to support patients. The procedure consists of transplanting individual cells to a recipient organ in sufficient quantity to survive and restore the function. The capacity of hepatic regeneration is the biological basis of hepatocyte transplantation. This therapeutic option is an experimental procedure in some patients with inborn errors of metabolism, fulminant hepatic failure and acute and chronic liver failure, as a bridge to orthotopic liver transplantation. In the Hospital La Fe of Valencia, we performed the first hepatocyte transplantation in Spain creating a new research work on transplant program. Copyright 2009 AEC. Published by Elsevier Espana.

Background Acute and chronic hepatitis E have been associated with high mortality and development of cirrhosis, particularly in solid-organ recipients and patients infected by human immunodeficiency virus. However, data regarding the epidemiology of hepatitis E in special populations is still limited. Aims Investigate seroprevalence and possible factors associated with HEV infection in a large cohort of immunosuppressed patients. Methods Cross-sectional study testing IgG anti-HEV in serum samples from 1373 consecutive individuals: 332 liver-transplant, 296 kidney-transplant, 6 dual organ recipients, 301 non-transplanted patients with chronic liver disease, 238 HIV-infected patients and 200 healthy controls. Results IgG anti-HEV was detected in 3.5% controls, 3.7% kidney recipients, 7.4% liver transplant without cirrhosis and 32.1% patients who developed post-transplant cirrhosis (p<0.01). In patients with chronic liver disease, IgG anti-HEV was also statistically higher in those with liver cirrhosis (2% vs 17.5%, p<0.01). HIV-infected patients showed an IgG anti-HEV rate of 9.2%, higher than those patients without HIV infection (p<0.03). Multivariate analysis showed that the factors independently associated with anti-HEV detection were liver cirrhosis, liver transplantation and HIV infection (OR: 7.6, 3.1 and 2.4). HCV infection was a protective factor for HEV infection (OR: 0.4). Conclusions HEV seroprevalence was high in liver transplant recipients, particularly those with liver cirrhosis. The difference in anti-HEV prevalence between Liver and Kidney transplanted cases suggests an association with advanced liver disease. Further research is needed to ascertain whether cirrhosis is a predisposing factor for HEV infection or whether HEV infection may play a role in the pathogeneses of cirrhosis. PMID:25068388

Liver transplantation is the best treatment for end stage liver diseases. In April 2003, our institution started a Liver Transplantation Program for both pediatric and adults population. Shown the results of the Liver Transplantation Program in the UMAE 25 Monterrey N.L. This is a retrospective cohort study of patients with liver transplantation. A total of 51 liver transplantations have been done in 49 patients with two retrasplantation, 15 in children and 36 in adults. The principal indication for liver transplantation in children was biliary atresia and hepatitis C cirrhosis in adults. The acute renal failure was the main early complication, the acute cellular rejection in the mediate period, and the cardiovascular diseases as late complication related to obesity, metabolic syndrome, diabetes mellitus and hypertension. Overall survival at 1 and 5 years was 57.1 and 54.2%, respectively. During the first three years post-transplantation, the quality of life was good or very good. Although still a young and perfectible program, the effort of a multidisciplinary team has made possible to perform liver transplantation in two patient populations, pediatric and adults.

Malignancies are a serious long-term complication among liver transplant recipients, with an overall incidence of 4.5%-15%. Posttransplantation lymphoproliferative disease (PTLD) is one of the leading causes of late death. Its development is related to complex interactions between immunosuppressive drugs and environmental agents. The aim of this study was to analyze risk factors for PTLD and survival after orthotopic liver transplantation (OLT) compared with solid tumors. We undertook a retrospective review of the clinical histories of adult patients who underwent OLT between July 1986 and February 2001, and who had been followed until 2005. This study comprised 528 adult recipients who survived more than 2 months after OLT. We excluded pediatric, partial-organ, and multiorgan recipients. No differences were observed concerning gender, viral etiology of hepatitis, calcineurin inhibitor regimen, or steroid maintenance period. Treated acute rejection episodes accounted for 53.3% of patients who developed PTLD compared with 47.3% in the control group (P = .787). Patients with solid tumors were older at the time of diagnosis than those with PTLD (57.5 +/- 8.13 years vs 48.8 +/- 13.9; P = .002). The overall mortality rate for PTLD was 55.5%, which did not differ significantly from solid tumors. PTLD develops in younger patients after OLT. Various immunosuppressive regimens do not seem to influence the incidence of PTLD or other solid tumors.

Background: Biliary complications remain a significant problem following liver transplantation. Several surgical options can be used to deal with a significant size mismatch between the donor and recipient bile ducts during the biliary anastomosis. We compared biliary transposition to recipient biliary ductoplasty in cadaveric liver transplant. Methods: A total of 33 reconstructions were performed from January 1, 2005 to December 31, 2013. In the biliary transposition group (n=23), 5 reconstructions were performed using an internal stent (5 or 8 French pediatric feeding tube), and 18 were performed without. Of the 10 biliary ductoplasties, 2 were performed with a stent. All patients were managed with standard immunosuppression and ursodiol. Follow-up ranged from 2 months to 5 years. Results: No patients in the biliary transposition group required reoperation; 1 patient had an internal stent removed for recurrent unexplained leukocytosis, and 2 patients required endoscopic retrograde cholangiography and stent placement for evidence of stricture. Three anastomotic leaks occurred in the biliary ductoplasty group, and 2 patients in the biliary ductoplasty group required reoperation for biliary complications. Conclusion: Our results indicate that biliary reconstruction can be performed with either biliary transposition or biliary ductoplasty. These techniques are particularly useful when a significant mismatch in diameter exists between the donor and recipient bile ducts. PMID:28331447

The purpose of this study was to analyze data from all adult and pediatric liver transplants performed between January 1, 1983 and January 15, 1986 at the University of Minnesota Hospital and identify perioperative variables that predict patient survival and could aid in patient selection. Charts, intraoperative anesthesia records, blood bank records, flow sheets, outpatient records, and autopsy reports were examined in 45 pediatric and 15 adult patients who underwent primary orthotopic liver transplantation. Analysis of the data can be summarized as follows: (1) Pediatric patients whose coagulation parameters could not be corrected prior to operation and who consequently required preoperative exchange transfusion had poorer outcomes than those not requiring an exchange to correct coagulation parameters. (2) The rapid infusion technique for massive blood transfusion resulted in significantly decreased blood loss and intraoperative blood product replacement. (3) Twenty-four hour postoperative factor V levels were good predictors of survival. Patients with poor factor V levels required rigorous replacement of coagulation factors. (4) Pediatric patients with uncorrectable coagulopathies requiring immediate postoperative exchange transfusion had extremely high mortality.

Liver transplantation (LT) was historically associated with massive blood loss and transfusion. Over the past two decades transfusion requirements have reduced dramatically and increasingly transfusion-free transplantation is a reality. Both bleeding and transfusion are associated with adverse outcomes in LT. Minimising bleeding and reducing unnecessary transfusions are therefore key goals in the perioperative period. As the understanding of the causes of bleeding has evolved so too have techniques to minimize or reduce the impact of blood loss. Surgical “piggyback” techniques, anaesthetic low central venous pressure and haemodilution strategies and the use of autologous cell salvage, point of care monitoring and targeted correction of coagulopathy, particularly through use of factor concentrates, have all contributed to declining reliance on allogenic blood products. Pre-emptive management of preoperative anaemia and adoption of more restrictive transfusion thresholds is increasingly common as patient blood management (PBM) gains momentum. Despite progress, increasing use of marginal grafts and transplantation of sicker recipients will continue to present new challenges in bleeding and transfusion management. Variation in practice across different centres and within the literature demonstrates the current lack of clear transfusion guidance. In this article we summarise the causes and predictors of bleeding and present the evidence for a variety of PBM strategies in LT. PMID:26722645

Immunosuppressive drugs and other medications may predispose patients to oral diseases. Data on oral mucosal health in recipients of liver transplantation (LT) are limited. We, therefore, recruited 84 LT recipients (64 with chronic liver disease and 20 with acute liver failure) for clinical oral examinations in a cross-sectional, case-control study. Their oral health had been clinically examined before transplantation. The prevalence of oral mucosal lesions (OMLs) was assessed in groups with different etiologies of liver disease and in groups with different immunosuppressive medications, and these groups were compared to controls selected from a nationwide survey in Finland (n = 252). Risk factors for OMLs were evaluated with logistic regression. OMLs were more frequent in LT recipients versus controls (43% versus 15%, P < 0.001), and the use of steroids raised the prevalence to 53%. Drug-induced gingival overgrowth was the single most common type of lesion, and its prevalence was significantly higher for patients using cyclosporine A (CSA; 29%) versus patients using tacrolimus (TAC; 5%, P = 0.007); the prevalence was even higher with the simultaneous use of calcium channel blockers and CSA (47%) or TAC (8%, P = 0.002). Lesions with malignant potential such as drug-induced lichenoid reactions, oral lichen planus-like lesions, leukoplakias, and ulcers occurred in 13% of the patients with chronic liver disease and in 6% of the controls. Every third patient with chronic liver disease had reduced salivary flow, and more than half of all patients were positive for Candida; this risk was higher with steroids. In conclusion, the high frequency of OMLs among LT recipients can be explained not only by immunosuppressive drugs but also by other medications. Because dry mouth affects oral health and OMLs may have the potential for malignant transformation, annual oral examinations are indicated. © 2013 American Association for the Study of Liver Diseases.

Leukoencephalopathy syndrome is a neurologic complication after organ transplantation caused predominantly by the neurotoxic effects of immunosuppressive agents on cerebral white matter. We determined the incidence and features of leukoencephalopathy syndrome in recipients after living-donor liver transplantations. We retrospectively investigated 205 patients who had a living-donor liver transplantation performed at our institution between August 1998 and October 2008. Leukoencephalopathy syndrome developed in 7 of 205 patients (3.9%) and in 4.7% of the 150 patients treated with tacrolimus-based immunosuppression after their living-donor liver transplantation. The underlying diseases were alcoholic cirrhosis in 3 cases, viral cirrhosis in 2, biliary atresia in 1, and Wilson disease in 1. Time to clinical onset after tacrolimus medication was 15.6 days (range, 6-30 days). The neurologic symptoms included headache, confusion, myoclonus, seizures, and visual disturbances. The mean serum trough level of tacrolimus at clinical onset was not very high (11.7 ng/mL [range, 6.0-14.2 ng/mL]). T2-weighted magnetic resonance imaging in all cases showed diffuse high signal in the white matter of the frontal, parieto-occipital, and temporal lobes. Treatment with antihypertensives, anticonvulsants, and withdrawal of tacrolimus resulted in amelioration of symptoms and magnetic resonance imaging abnormalities. Six patients showed complete recovery, while the seventh had residual rigidity and cognitive impairment caused by hypoxia during a convulsion. Tacrolimus neurotoxicity can occur despite low trough levels; it depends on variations in pharmacokinetics, such as absorption and maximum concentration level. Early diagnosis and treatment of leukoencephalopathy syndrome should contribute to complete remission.

New-onset diabetes after transplantation (NODAT) is a serious complication of liver transplantation (LT). The present study aimed to investigate the risk factors of NODAT by a national survey using the China Liver Transplant Registry database. A total of 10 204 non-pre-existing diabetic patients undergone primary LT between January 2000 and December 2013 were included. Risk factors were identified by logistic regression analysis. NODAT occurred in 24.3% of liver recipients with a median follow-up time of 2.6 years, and was associated with a significantly lower patient survival. NODAT increased not only diabetes related complications (e.g., infection, kidney failure) but also biliary stricture and cholangitis. NODAT patients who received hypoglycaemic treatment had a worse prognosis and a higher hepatocellular carcinoma recurrence compared with those without treatment. New-onset hyperglycaemia (<30 days) was the major predictor of NODAT. Other risk factors included cold ischaemia time >9 h, recipient age >50 years, body mass index >25 kg/m(2) , other hepatitis (mainly hepatitis C), post-transplant intensive care unit stay >15 days, cytomegalovirus infection and corticosteroid at discharge. The incidence of NODAT in China is similar to that in Western countries. However, the NODAT-related complications are more common and severer in China compared with those in Western countries. The major risk factors are different. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

A prerequisite dental evaluation is usually recommended for potential organ transplant candidates. This is based on the premise that untreated dental disease may pose a risk for infection and sepsis, although there is no evidence that this has occurred in organ transplant candidates or recipients. The purpose of this study was to assess the prevalence of dental disease and oral health behaviors in a sample of liver transplant candidates (LTCs). Oral examinations were conducted on 300 LTCs for the presence of gingivitis, dental plaque, dental caries, periodontal disease, edentulism, and xerostomia. The prevalence of these conditions was compared with oral health data from national health surveys and examined for possible associations with most recent dental visit, smoking, and type of liver disease. Significant risk factors for plaque-related gingivitis included intervals of more than 1 yr since the last dental visit (P = 0.004), smoking (P = 0.03), and diuretic therapy (P = 0.005). Dental caries and periodontal disease were also significantly associated with intervals of more than 1 yr since the last dental visit (P = 0.004). LTCs with viral hepatitis or alcoholic cirrhosis had the highest smoking rate (78.8%). Higher rates of edentulism occurred among older LTCs who were less likely to have had a recent dental evaluation (mean 88 months). In conclusion, intervals of more than 1 yr since the last dental visit, smoking, and diuretic therapy appear to be the most significant determinants of dental disease and the need for a pretransplantation dental screening evaluation in LTCs. Edentulous patients should have periodic examinations for oral cancer.

Familial amyloid polyneuropathy (FAP) is a systemic amyloidosis caused by mutated transthyretin. Cardiac amyloidosis, the major prognostic determinant in systemic amyloidosis, is characterized by infiltration of the myocardium, leading to cardiomyopathy and conduction disturbances. Liver transplantation is the only curative option for patients with FAP. The case is presented of a 36-year-old patient with type i FAP with cardiac involvement, proposed for liver transplant surgery, which was successfully performed without any preoperative event of interest.

Liver or kidney transplant recipients are at a higher risk of developing tuberculosis (TB) than general population. We aimed to clarify the incidence density of and risk factors for TB in liver or kidney transplant recipients in the present study. All patients with TB following liver or kidney transplantation were investigated retrospectively at the Third Xiangya Hospital, Central South University, Changsha, China. The incidence density of TB was calculated. We performed a nested case-control study (1:1) to investigate by univariate and multivariate logistic regression analysis the potential risk factors for TB. From January 2000 to August 2013, 1748 kidney and 166 liver transplant recipients were performed at a university teaching hospital. Among the 1914 recipients, 45 cases (2.4%) of TB were reported. The incidence density was 506 cases per 105 patient-years in kidney or liver transplant recipients, which was 7 times higher than in the general Chinese population (around 70 cases per 105 person-years). The median time to develop TB was 20.0 months (interquartile ratio: 5.0-70.0). The receipt of a graft from a cadaveric donor (odds ratio [OR] = 3.7; 95% confidence interval [CI] = 1.4-10.0; P = 0.010) and the preoperative evidence of latent TB (OR = 6.8; 95% CI = 2.0-22.7; P = 0.002) were identified as two risk factors for developing TB in liver or kidney transplant recipients. The incidence density of TB among liver or kidney transplant recipients was much higher than in the general Chinese population. Recipients receiving a graft from a cadaveric donor and the preoperative evidence of latent TB were two major risk factors for developing TB in liver or kidney transplant recipients.

Hereditary haemorrhagic telangiectasia is characterized by arterio-venous malformations (AVM). It frequently involves the liver without clinical symptoms, but may lead to biliary ischaemia, portal hypertension, or fatal high-output heart failure. The indication of liver transplantation is controversial. Herein, we report the case of a 65-year-old female patient with a 'double Osler syndrome' consisting of hereditary haemorrhagic telangiectasia (HHT) and type I hereditary angioedema diagnosed at the age of 25 and 22 years respectively. Hereditary angioedema was treated with danazol for several decades until multiple hypoechogenic liver masses were detected. Albeit danazol treatment was replaced by C1 esterase inhibitor infusions, hepatocellular carcinoma was diagnosed at the age of 64 and the patient was listed for liver transplantation. HHT was marked by recurrent epistaxis until the age of 63 when severe intestinal bleeding occurred. At the age of 65, severe dyspnoea (NYHA class IV) developed and rapidly progressive high-output cardiac failure was diagnosed. Despite argon plasma coagulation to control bleeding from intestinal angiodysplasia, and treatment with bevacizumab to inhibit angiogenesis, the patient died from severe gastrointestinal bleeding associated with cardiogenic shock at the age of 66 before being transplanted. The indication to list this patient for liver transplantation was debated several times before the diagnosis of hepatocellular carcinoma because of good general condition and low MELD score. Precise guidelines for screening and management of patients with hepatic HHT need to be better defined. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.
