RESUMO

Colorectal cancer (CRC) has the second-highest tumor incidence and is a leading cause of death by cancer. Nearly 20% of patients with CRC will have metastases at the time of diagnosis, and more than 50% of patients with CRC develop metastatic disease during the course of their disease. A group of experts from the Spanish Society of Medical Oncology, the Spanish Association of Surgeons, the Spanish Society of Radiation Oncology, the Spanish Society of Vascular and Interventional Radiology, and the Spanish Society of Nuclear Medicine and Molecular Imaging met to discuss and provide a multidisciplinary consensus on the management of liver metastases in patients with CRC. The group defined the different scenarios in which the disease can present: fit or unfit patients with resectable liver metastases, patients with potential resectable liver metastases, and patients with unresectable liver metastases. Within each scenario, the different strategies and therapeutic approaches are discussed.

RESUMO

Herein we report a case of liver dysfunction caused by consumption of vitamin A supplements leading to liver transplantation. The patient was a 48-year-old male with a medical history of congenital ichthyosiform erythroderma in treatment with vitamin A until 12 years of age, at which point he discontinued the supplements because he had developed ascites. Liver cirrhosis was diagnosed as secondary to hypervitaminosis A on the basis of histologic examination of liver biopsy and the absence of other potential causes of chronic liver disease. Despite interruption of administration of vitamin A, the patient continued to deteriorate over the years, with development of portal hypertension signs. His medical conditions were aggravated with the development of hepatic insufficiency manifested by refractory ascites, renal insufficiency, and severe encephalopathy and he underwent orthotopic liver transplantation, followed by disappearance of all signs of portal hypertension. This case highlights the need to take a careful history of consumption of vitamin A when evaluating a patient with liver failure.

RESUMO

The goal of this work has been to analyze the first 1000 liver transplantations (LTs) performed in the Virgen del Rocío Hospital of Seville and to evaluate the changes in that time. We included 916 patients who had 1000 LTs. We distinguish 2 stages in the follow-up: the first stage, between 1990 and 2002, and the second, from 2003 to 2013 (Model for End-stage Liver Disease [MELD] stage). We analyzed recipient features, LT indications, donation criteria, surgical technique, complications, and survival both for patients and grafts. The median age of recipients was 53.50 ± 46.49 years old, with a noticeable increase after 2000. There were 3 times as many men as women. The most frequent indications for LT were hepatocellular disease (48.8%), followed by hepatocarcinoma (17.8%), retransplantation (8.1%), and cholestatic diseases (3.6%). Donors of Andalusian centers accounted for 88.2% of LTs, and 8.3% of LTs presented some arterial or venous complication. Biliary complications occurred in 15.6%. Patient survival at 1, 5, and 10 years was 77%, 63.5%, and 51.3%, respectively. In conclusion, some of the factors that negatively influenced survival of the patient were stage of the LT, hepatitis C virus-positive recipient, emergency cases, hepatocarcinoma, high consumption of blood products, and second transplantations.

RESUMO

Recently, there has been a large discrepancy between the number of patients on the waiting list for a liver transplant and the availability of deceased donors, with an increase in annual wait list mortality rates. Elderly donor livers are thought to be marginal grafts; however, in recent years, their utilization has constantly increased. The aim of this study is to evaluate the utilization of elderly donors in Andalusia and post-transplant outcomes. This retrospective observational study of 2408 liver transplants, performed in Andalusia between 2000 and 2014, analyzes the outcomes from donors aged 70 plus (n = 423) in terms of survival rates of the graft and the recipient, the type of transplant, donor age, and D-MELD score (product of donor age and preoperative Model for End-stage Liver Disease score). The most frequent indications for transplant were alcoholic cirrhosis (49.2%), hepatitis C cirrhosis (13%), and hepatocellular carcinoma (12.5%). The overall survival at 5 years was 64%, with a significant fall in survival for recipients with a D-MELD greater than 1500 (57%; P = .045). In the 70-year-old-plus donor group, the overall patient survival was 58.4%. The retransplant rate increased proportionately with donor age. In the alcoholic cirrhosis recipient subgroup, the overall survival at 5 years was 67.6% (P < .05) compared with 33.5% in patients with hepatitis C. Use of elderly donors is a safe strategy to reduce the scarcity of donors, provided that a D-MELD score below 1500 is obtained. Retransplant rates increase progressively with donor age. It is necessary to carefully screen recipients of older organs, taking into account that the best results are obtained for alcoholic cirrhosis, negative viral load hepatitis C, and a D-MELD score below 1500.

RESUMO

BACKGROUND: Survival after orthotopic liver transplantation (LT) for hepatocellular carcinoma (HCC) is influenced by tumor recurrence. This study examines the survival of patients who underwent LT for HCC and developed recurrence of tumor after transplantation. METHODS: A retrospective analysis was performed of the 200 patients who underwent LT secondary to HCC from 1990 to 2014. We excluded 19 patients from the study owing to early postoperative deaths in the 1st month. We divided our sample into 2 groups according to the presence of recurrence. We performed a univariate analysis to identify variables that are significantly associated with the risk of recurrence. Afterward we use multivariate analysis regression analysis to find independent significance. RESULTS: Univariate analysis shows significant relationship between high Edmondson-Steiner grades (G3-G4) and the development of tumor recurrence. Tumor size, vascular invasion, and capsular invasion were found to be independent risk factors of tumor recurrence in the multivariate analysis. CONCLUSIONS: Tumor recurrence defines survival of patients who underwent LT for HCC. In this study we discuss which histologic factor are associated with higher risk of tumor recurrence, and therefore a negative the impact on patient's survival.

RESUMO

p53 is the most commonly mutated gene in malignant human cancers. To detect p53 mutations in circulating DNA (cirDNA) of transplanted hepatocellular carcinoma (HCC) patients could be an interesting approach to know of any tumor recurrence. In this study, our objective was to determine the utility of this method in the diagnosis and the prognosis of HCC tumor recurrence.Twenty four liver transplanted HCC patients were included in the study together with a group of healthy controls. Detection of the specific p53 mutation in cirDNA was performed by high-resolution melting PCR (HRM-PCR) and COLD-PCR immediately before the transplantation. Serum anti-p53 was also determined using a p53-autoantibody ELISA kit.The results of the HRM-PCR and COLD-PCR showed two well-differentiated groups of transplanted patients after normalization by healthy controls. These data allow us to distinguish between patients with p53 mutated cirDNA and those with wild type cirDNA. Moreover, we have found that most of p53 mutated patients also presented elevated anti-p53 antibodies. The present results indicate that it is possible to detect mutated p53 genes with the cirDNA and that this could be used as a biomarker of tumor recurrence during the clinical evolution of the transplanted patients.

RESUMO

The evaluation of the transplanted liver health by non-invasive approaches may offer an improvement in early clinical intervention. As transplanted organs have genomes that are distinct from the host's genome, the quantification of the specific DNA of the donated liver in the patient serum will allow us to obtain information about its damage. We evaluated the state of transplanted liver health by monitoring the RH gene in serum circulating DNA (cirDNA) from 17 recipient and donor mismatched for this gene. cirDNA RH gene was quantified by RT- PCR before, at the moment of transplantation (day 0) and during the stay at the intensive care unit. Beta-globin cirDNA was quantified as a general cellular damage marker. Patients were grouped based on clinical outcomes: (A) patients with no complication; (B) patients that accepted the organ but suffered other complications; (C) patients that suffered organ rejection. All patients showed an increased cirDNA levels at day 0 that decreased until patient stabilization. Patients from groups A and B showed low levels of the RH gene cDNA during the follow-up, with an increase of beta-globin gene at the moment of any clinical complication. Patients from group C showed an increase in the RH gene during rejection.

RESUMO

OBJECTIVES: Although a CMV-specific T-cell response is associated with reduced risk for infection after transplantation, some patients still develop CMV disease. Thus, the characterization of additional parameters of the CMV-specific immune response that correlate with the control of CMV infection and disease and their use in defining thresholds that can be applied to clinical practice is of interest. METHODS: In a cohort of high risk solid organ transplant recipients we characterized CMV-specific T-cell responses using intracellular cytokine staining upon stimulation with pp65 and IE-1 peptides, and levels of CMV-specific antibodies neutralizing infection in fibroblast (MRC-5) and epithelial (ARPE-19) cells using microneutralization assays. RESULTS: Although patients with a positive (≥0.25%CD8(+)CD69(+)IFN-γ+) T-cell response were 6.4 fold more protected (OR 6.4, 95% CI 1.6-25.3; p < 0.001) from CMV infection than patients without a response, 2 (4.2%) patients developed disease. We defined a cut-off titer for epithelial cell neutralizing antibodies of ≥480 that correlated with disease protection. Thus, patients with a CMV-specific T-cell response and titers ≥480 were 14.2 fold more protected from CMV infection (OR 14.2, 95% CI 5-40.2; p < 0.001) and had no episodes of CMV disease. CONCLUSIONS: Our results indicate that antibodies neutralizing epithelial cell infection may have an important role in long-term protection. Quantification of antibodies neutralizing epithelial cells, in addition to the T-cell response, may be useful for identifying patients with lower risk for CMV disease.

RESUMO

Biliary atresia (BA) is a neonatal progressive cholangiopathy of unknown etiology and one of the most common reasons for liver transplantation (LT) in children. Kasai portoenterostomy (KP) improves survival of the native liver, although LT remains the only ultimate treatment. In some cases KP makes it possible to defer the ultimate LT until adulthood. We report our experience regarding 5 cases of BA treated with LT during adulthood. KP was performed in all patients at an average age of 176 days (range, 60-280), which allowed an average survival of the native liver of 19.01 years (range, 14.06-22.32). Five-year survival rate was 100%. Ten-year survival rate did not reach 100% because of a death 9.55 years after LT due to chronic graft rejection, in a patient who was already prepared for a new LT. Our results corroborate that KP remains the first-line treatment of BA. Early performance of the KP provides children with the best chance of survival, allowing the delay of the LT to adulthood. LT during adulthood in these patients achieves good post-LT survival rate; we have not found any data regarding this group of patients in the literature.

RESUMO

Nitric oxide (NO) plays a relevant role during cell death regulation in tumor cells. The overexpression of nitric oxide synthase type III (NOS-3) induces oxidative and nitrosative stress, p53 and cell death receptor expression and apoptosis in hepatoblastoma cells. S-nitrosylation of cell death receptor modulates apoptosis. Sorafenib is the unique recommended molecular-targeted drug for the treatment of patients with advanced hepatocellular carcinoma. The present study was addressed to elucidate the potential role of NO during Sorafenib-induced cell death in HepG2 cells. We determined the intra- and extracellular NO concentration, cell death receptor expression and their S-nitrosylation modifications, and apoptotic signaling in Sorafenib-treated HepG2 cells. The effect of NO donors on above parameters has also been determined. Sorafenib induced apoptosis in HepG2 cells. However, low concentration of the drug (10nM) increased cell death receptor expression, as well as caspase-8 and -9 activation, but without activation of downstream apoptotic markers. In contrast, Sorafenib (10 µM) reduced upstream apoptotic parameters but increased caspase-3 activation and DNA fragmentation in HepG2 cells. The shift of cell death signaling pathway was associated with a reduction of S-nitrosylation of cell death receptors in Sorafenib-treated cells. The administration of NO donors increased S-nitrosylation of cell death receptors and overall induction of cell death markers in control and Sorafenib-treated cells. In conclusion, Sorafenib induced alteration of cell death receptor S-nitrosylation status which may have a relevant repercussion on cell death signaling in hepatoblastoma cells.

RESUMO

BACKGROUND: The seroma generated between the abdominal viscera and the prosthesis (retroprosthetic seroma), after laparoscopic ventral hernia repair (LVHR) with the implant of an intraperitoneal mesh is an unknown entity with few references in the literature. Our objective is to analyze its incidence, clinical repercussions and course of retroprosthetic seroma during the first 3 months post-operation and the factors related to its appearance, such as the relationship to preprosthetic seroma, the size of the prosthesis and the patient BMI. MATERIALS AND METHODS: Prospective, descriptive study in patients undergoing LVHR using the double crown technique. After surgery, the patients had follow-ups on the seventh day and the first and third months post-operation with clinical examination and abdominal CT scan. The study endpoints were: incidence and volume of retroprosthetic seroma, clinical repercussions, relationship to body mass index (BMI), prosthesis size and the existence of preprosthetic seroma. RESULTS: Fifty patients underwent LVHR using the double crown technique and were included in the study. The incidence of retroprosthetic seroma during the 3-month follow-up was 46%, there being a progressive process of spontaneous reabsorption. In just one patient (2%) there were clinical repercussions as a result of the seroma. No statistically significant relationship was found with BMI and preprosthetic seroma. A statistical relationship was found between the size of the prosthesis and the risk of suffering retroprosthetic seroma in the third month post-operation (p = 0.048). CONCLUSIONS: Retroprosthetic seroma is an entity produced in 46% of patients undergoing LVHR with few clinical repercussions (2%). In most cases it develops in the first week post-operation and then undergoes a reabsorption process that is usually complete by the third month post-operation. The size of the prosthesis delays the reabsorption process.

RESUMO

Domino liver transplantation (DLT) is a strategy used to increase the number of available grafts. In this procedure, the transplant recipient is a living donor of her own liver. It is mandatory that the graft should be fully functional and the genetic defect should recur with sufficient latency period in the new recipient. Corino-Andrade disease, or familial amyloidotic polyneuropathy (FAP), satisfies these conditions. We retrospectively reviewed our prospective database of DLT. From July 2004 to April 2013, we performed 12 DLTs. We assessed age, sex, real Model for End-Stage Liver Disease (MELD) score, waiting list time, cold and warm ischemia times, intraoperative transfusion requirements, hospital stay, early peritransplantation morbidity (post-reperfusion syndrome, intraoperative cardiac arrest, post-transplantation thrombotic events, and biliary morbidity), acute cellular rejection, retransplantation, mortality, patient and graft survivals. With the intention to study the effect of the learning curve in the global survival results (including both donors and recipients of livers with FAP), we divided our series into 2 periods: the early period (from 2004 to 2008) and the present period (from 2009 to 2013). The crude mortality was 40% vs 0% (P = .042) in the early and present periods, respectively. The cumulative patient survival was also significantly in favor of the present period (P = .049). The graft loss prevalence was 60% vs 7.1% (P = .019) in the early and present periods, respectively. The cumulative graft survival was also significantly in favor of the present period (P = .030; Fig 2). In conclusion, we consider DLT to be a complex procedure, whose initial results are conditioned by the learning curve.

RESUMO

Von Gierke's disease or glycogen storage disease type Ia (GSD-Ia) is an infrequent metabolic disease caused by an atypical accumulation of glycogen. The principal cause of this pathology is deficiency of the glucose-6-phosphatase enzyme. Herein we have reported a case of a young man with a history of Von Gierke's disease (GSD-Ia) since childhood who developed hepatocellular adenomatosis brought to light by ultrasounds and TACs. The patient began to develop early chronic renal failure, necessitating simultaneous liver and kidney transplantation. Years later continuous reviews at the nephrology and hepatobiliopancreatic surgery services show he has a good quality of life and a normal hepatorenal profile.

RESUMO

We report our experience with a 61-year-old patient with alcoholic and hepatitis C cirrhosis who underwent liver transplantation. On the 3rd postoperative day he presented a mediastinitis secondary to esophageal perforation produced by a Linton tube. An esophagectomy with jejunostomy was performed. Tacrolimus granules for oral suspension (Modigraf) were administered through the jejunostomy. This case report highlights the use of Modigraf and the absence of secondary effects. We observed biochemical parameters during the jejunostomy period. We discuss the administration strategy applied and whether tacrolimus granules for oral suspension by jejunostomy affect the bioavailability and its side effects.

RESUMO

OBJECTIVES: To analyze the epidemiology, causes, complications, and mortality of liver transplants following fulminant hepatic failure over the last 16 years. MATERIALS AND METHODS: We completed a descriptive analysis of 21 patients with fulminant hepatic failure and a liver transplant. In almost half of the cases, the origin of liver failure was unknown. RESULTS: The mean age was 36 years; the study group was 47.61% female (n = 10) and 52.39% male (n = 11). The most common early complication was transplant rejection, which occurred in 33.3% of all patients (n = 7) and was confirmed by liver biopsy; the most frequent long-term complication was autoimmune hepatitis. Two retransplantations were necessary. The total mortality rate was 38.1% (n = 8) with late mortality in three patients (14.3%). CONCLUSIONS: Orthotopic liver transplantation as a treatment for fulminant hepatitis has a higher mortality rate than orthotopic liver transplantation due to other causes. It does, however, enable the survival of 62% of the patients who otherwise would have died due to liver failure. The etiology of most of the cases was unknown. We should point out the high incidence rates for transplant rejection and late autoimmune hepatitis, in addition to the possibility of hemorrhagic colonic diseases that may be associated with the condition causing liver failure. Multidisciplinary control over the patient is useful for deciding at which time a liver transplant would become the only treatment option.

RESUMO

Hepatic artery complications after orthotopic liver transplantation are associated with a high rate of graft loss and mortality (23% to 35%) because they can lead to liver ischemia. The reported incidence of hepatic artery thrombosis (HAT) after adult liver transplantation is 2.5% to 6.8%. Typically, these patients are treated with urgent surgical revascularization or emergent liver retransplantation. Since January 2007, we have recorded the postanastomotic hepatic artery flow after revascularization. The aim of this study was to assess the relationship between hepatic blood flow on revascularization and early HAT. Retrospectively, we reviewed perioperative variables from 110 consecutive liver transplantation performed at the Virgen del Rocío University Hospital (Seville, Spain) between January 2007 and October 2010. We evaluated the following preoperative (donor and recipient) and intraoperative variables: donor and recipient age, cytomegalovirus serology, ABO-compatibility, anatomical variations of the donor hepatic artery, number of arterial anastomoses, portal and hepatic artery flow before closure, cold ischemia time, and blood transfusion. These variables were included in a univariate analysis. Of the 110 patients included in the study, 85 (77.7%) were male. The median age was 52 years. ABO blood groups were identical between donor and recipient in all the patients. The prevalence of early HAT was 6.36% (7 of 110). Crude mortality with/without HAT was 22% versus 2% (P = .001), respectively. Crude graft loss rate with/without HAT was 27% versus 4% (P = .003), respectively. Early HAT was shown to be primarily associated with intraoperative hepatic artery blood flow (93.3 mL/min recipients with HAT versus 187.7 mL/min recipients without HAT, P < .0001). No retransplantation showed early HAT. In our experience, intraoperative hepatic artery blood flow predicts early HAT after liver transplantation.

RESUMO

BACKGROUND: Hepatitis C virus (HCV) clearance is an independent predictive factor for long-term survival in HIV-HCV liver transplantation patients. After 46 months of antiviral therapy it is achieved in up to 80% of cases. Little is known, however, about spontaneous viral clearance. We performed prospective study of HIV-HCV coinfected liver transplant patients. METHODS: Between January 1, 2001, and December 31, 2011, we analyzed the parameters from among HIV-HCV coinfected liver transplant patients of donor and recipient ages, transplant cause, Model for End-Stage Liver Disease (MELD) score, donor and recipient serology, transplant date, viral load before and after transplantation, immunosuppressive therapy, HCV recurrence, HCV viral clearance (spontaneous and duration), retransplant cause, and viral load before and after retransplant, as well as survival. RESULTS: The seven transplanted HIV-HCV coinfected patients had most commonly HCV-related hepatocarcinoma (n = 5, 71.42%). Three subjects (42.85%) developed HCV recurrences. Two patients (28.57%) were retransplanted, both due to HCV recurrence with one of them developing a spontaneous clearance of HCV (14.28%). This patient showed a preoperative HIV viral load < 50 copies IU/mL, CD4+ count 486/µL, HCV-RNA 2564 IU copies/mL, Anti-HBc+, and MELD 30. The donor was an 81-year-old female who was Anti-HBc+. Immunosuppressive therapy consisted of cyclosporine, mycophenolate, and prednisone. One month after transplantation, the patient developed an acute cellular rejection episode with progression of liver disease secondary to the HCV recurrence (56.5 × 105 copies IU/mL). He started antiviral treatment (α-interferon and ribavirin), but due to side effects and interactions with the antiretrovirals, they were stopped after four doses. The viral load decreased spontaneously and progressively until it became negative at 146 days after transplantation; he was retransplanted and HCV-RNA has continued to be negative after 772 days. CONCLUSION: Spontaneous clearance of HCV among HIV-HCV coinfected liver transplant patients is possible. Despite no treatment, one patient still has no detectable HCV viral load after retransplantation.

RESUMO

We performed a retrospective study to evaluate the rate of and factors associated with a response to recombinant hepatitis B virus (HBV) vaccination using 4 intramuscular doses (40 µg) administered at 0, 1, 2, and 6 months among 278 cirrhotic patients being evaluated for orthotopic liver transplantation (OLT). We re-vaccinated 57 non-responders with the same schedule. The 39.2% overall response rate to vaccination included 36% after three and 40.7% after four doses, namely, a median anti-HBs level of 100 IU/mL (range, 10 to 1000 IU/mL). The 51% revaccination response rate achieved a median hepatitis B surface antibody (anti-HBs) level of 99 IU/mL (range, 11 to >1000 IU/mL). Upon univariate analysis, variables associated with a higher response were: better liver function (Child-Pugh class [A, 53.8% B, 33.3%, C, 30.1%; P = .002), Model for End-stage Liver-Disease (MELD) score (11.4 versus 13.6; P = .001]), absence of diabetes (43.6% versus 20.8%; P = .002), presence of isolated hepatitis B core antibody (anti-HBc) positivity (80% versus 37.7%; P = .007), and younger age (< 45 years, 52.2%; range, 45 to 55 years, 40.4%; > 55 years, 34.1%; P = .031). Upon multivariate logistic regression analysis, lower MELD score (odds ratio [OR]: 0.922; P = .046), absence of diabetes (OR:0.359; P = .008) and isolated anti-HBc positivity (OR:5.826; P = .034) were associated with a higher response. No differences were observed to be associated with gender, weight, body mass index, etiology or tobacco consumption. Among the same patient cohort (n = 79), the responses after the third and fourth doses were 36.7% and 51.9% respectively. In conclusion, the response rate to HBV vaccination in cirrhotic patients evaluated for OLT reached more than 35% among those who received at least 3 doses. It was higher among patients who showed isolated anti-HBc positivity, better liver function, younger age, and non-diabetic status. The fourth dose only increased the response rate by 24% over that obtained after the first three doses, whereas a revaccination achieved a 50% response rate, which probably accounts for revaccination after no response to 3 doses. Vaccination should be introduced against HBV in the early stages of the disease.

RESUMO

In the absence of immunity, vaccination against hepatitis A virus (HAV) and hepatitis B virus (HBV) is recommended for patients with chronic liver disease and those evaluated for liver transplantation (OLT) HAV and HBV infections after OLT which are frequent in this setting, are associated with a worse prognosis. The aim of this study was to estimate the need for vaccination against HBV and HAV among cirrhotic patients who were candidates for OLT and associations with gender, age, and etiologic factors. HBV and HAV serological markers HBsAg, anti-HBc, antiHBs, immunoglobulin G (IgG)-anti-HAV were investigated among 568 patients, including 75% men. The overall mean age was 53.6 ± 8.9 years range 17-69, and 20% were diabetic. This etiologies were alcohol (68%), hepatitis C virus (35%) or other causes (10.4%). Child-Pugh classes were: A (26%), B (44%), and C (30%). In contrast with 359 patients (63.2%) who had negative HBV markers, 209 (36.8%) were positive: HBsAg (+), 43 (7.6%), isolated anti-HBc (+), 57 (10%), isolated anti-HBs (+), 19 (3.3%), anti-HBc (+)/anti-HBs (+), 90 (15.8%). HBV vaccine indication was performed in 416 patients (73.2%) who either had negative HBV markers or isolated anti-HBc (+). It was more frequently performed in women (82.3% versus 70.3%, P = .005), albeit with no differences according to age or etiology. There were only 8.2% (44/538) IgG-anti-HAV-negative, an indication for vaccination against HAV, which was more frequent affecting patients who were younger [≤ 45 years (27.6%), 46-55 (7.2%), >55 (2.6%); P < .0001)]; nondiabetic (9.5% versus 2.8%, P = .023); nonalcoholic (11.4% versus 6.6%, P = .056); and displayed negative HBV markers (10.2% versus 4.6%, P = .023). Only three patients with IgG-anti- HAV (-) were over 60 years. In conclusion, there is a frequent indication for HBV vaccination among cirrhotic and especially HAV vaccine for under 45 year old patients undergoing evaluation for OLT.
