The most accepted hypothesis about the pathogenesis of ascites and renal failure in cirrhosis nowadays is based on the peripheral arterial vasodilation hypothesis and the forward theory of ascites formation proposed by Schrier et al menopause pregnancy buy generic nolvadex pills. The peripheral arterial vasodilation hypothesis holds that the primary event of renal sodium and water retention in cirrhosis is a splanchnic arterial vasodilation caused by a massive release of local vasodilators. In the initial phases of cirrhosis, compensation occurs through the development of hyperdynamic circulation (high plasma volume, cardiac index, and heart rate). As cirrhosis progresses and splanchnic arterial vasodilation increases, this compensatory mechanism is insufficient to maintain circulatory homeostasis. The forward theory of ascites formation follows from the peripheral arterial vasodilation hypothesis and holds that arterial vasodilation in the splanchnic circulation induces the formation of ascites by simultaneously impairing the systemic circulation (leading to sodium and water retention), and the splanchnic microcirculation (where the forward increase in capillary pressure and permeability from the greatly increased inflow of blood at high pressure into the splanchnic capillaries leads to the leakage of fluid into the abdominal cavity). First, several studies have shown that cardiac function is increased (hyperdynamic circulation with increased cardiac output) in early stages of cirrhosis and ascites but declines with the progression of the disease, being frequently normal in patients with hepatorenal syndrome. Second, the peripheral arterial vasodilation hypothesis does not consider that patients with advanced cirrhosis frequently develop multiorgan failure (acuteon-chronic liver failure), a syndrome characterized by systemic inflammation and high short-term mortality. According to this new hypothesis, systemic inflammation could also contribute to the major clinical manifestations of advanced cirrhosis. The sustained activation of the innate immune system caused by an abnormal translocation of bacteria and bacterial products from the intestinal lumen (pathogen-associated molecular patterns) leads to the persistent activation of the innate pattern recognition receptors and subsequent chronic inflammation. Proinflammatory cytokines and oxidative stress accentuate circulatory dysfunction (by enhancing arterial vasodilation and cardiac dysfunction) and damage kidney and other organs, thereby worsening their function [12]. The hepatic sinusoid lacks a basement membrane and is therefore more permeable than the bowel. The large hydrostatic pressure gradient present in the portal hypertensive liver leads to loss of intravascular fluid across the hepatic sinusoids into the space of Disse, and weeping of the fluid from the liver surface as extravasated lymph. Now many patients have chronic hepatitis C and excess alcohol use in the setting of obesity. Patients who have a component of alcoholic liver disease and who intermittently reduce alcohol consumption may experience wet/dry cycles in terms of fluid retention. The cycles of ascites may be separated by years of normal sodium balance and tend to parallel their alcohol consumption. In contrast, patients who develop ascites with nonalcoholic liver disease tend to be persistently fluid overloaded, probably due to the late stage at which ascites forms in nonalcoholic liver disease and the lack of effective therapy other than liver transplantation. These patients can also have a dramatic response to (noninterferon-based) antiviral therapy. Similar responses could be observed in cirrhotic patients with hepatitis C receiving interferon-free directly active antiviral therapy. When the patient has a very long history of stable cirrhosis and then develops ascites, the possibility of hepatocellular carcinoma should be considered as the cause for decompensation. Patients with ascites should also be questioned about risk factors for liver disease other than alcohol. Asking the patient about lifetime maximum body weight, diabetes, and number of years of being overweight/obese can provide a cause for cirrhosis that may have been thought to be "cryptogenic" [16]. Patients who have a history of cancer and develop ascites should be suspected of having malignancy-related ascites. Patients with malignancyrelated ascites frequently have abdominal pain, whereas ascites due to cirrhosis is usually not associated with abdominal pain unless there is superimposed bacterial peritonitis. Patients with cardiac ascites often have a past history of heart failure or lung disease. Alcoholics who develop ascites may have alcoholic cardiomyopathy and liver disease. More than one half of patients with tuberculous peritonitis have underlying cirrhosis as a second cause for ascites formation. Patients who develop ascites and anasarca in the setting of longstanding diabetes should be suspected of having nephrotic ascites. Ascites developing in a patient with cold intolerance, lethargy, altered bowel motility, changes in the skin, etc. Physical examination the details of the physical examination in detecting ascites are also discussed at the beginning of this chapter. The fluid wave has not been found to be of much value in the detection of ascites [3]. A simple ultrasound, which is available to many hepatologists now, can rule in ascites very rapidly, especially in the obese patient, where physical examination is difficult due to the thick panniculus. The presence of palmar erythema or large vascular spiders is very suggestive of the presence of cirrhosis. The presence of pathologically large abdominal wall collateral veins suggests that portal hypertension is present. The presence of large veins on the flanks and dorsum of the patient suggests inferior vena cava blockage by a fibrous caval web or malignant obstruction. The neck veins of patients with ascites should always be examined for distension in pursuit of a cardiac origin of ascites. Some patients with cardiac ascites will have bulging forehead veins that can be seen from across the room. When patients with liver disease have peripheral edema, it is usually in the lower extremities and spares the arms. Patients with cardiac failure or nephrotic syndrome may have leg and arm edema. Ascites may be quantified using the following system: r 1+: detectable only by careful examination r 2+: easily detected but of relatively small volume r 3+: obvious ascites but not tense r 4+: tense ascites.

Other grafts may present with a less dramatic picture breast cancer chemotherapy order nolvadex with american express, demonstrating prolonged cholestasis, evidence of ischemic/harvest injury on biopsy, and slow or inadequate restoration of function. These patients often have prolonged intensive care unit stays with an increased risk of serious infectious complications, graft loss, and death [22,23]. Each of these factors has been associated with decreased graft survival, thereby leading to an increased potential need for retransplantation. Previously, these grafts were used in patients in desperate situations and were associated with dismal graft and patient survival. There is some debate as to which patients are acceptable candidates for these grafts, but in general less critically ill recipients are appropriate, as more stable patients may be able to better tolerate a period of relative graft dysfunction or the need for a retransplant procedure [26]. Although this matching of donor to recipient is ideal, it is often not possible with our current allocation system, which does not factor in graft quality. The use of fibrinolysis, surgical thrombectomy, and immediate revascularization may avoid the necessity of retransplantation in some instances, but most patients still need a second graft. Chapter 47: the Role of Retransplantation 1149 Indications for late retransplantation Chronic rejection Current modalities in immunosuppression have essentially eliminated the need for retransplantation for acute rejection, and the incidence of retransplantation for chronic rejection has declined significantly. In a large series from Gainesville, Florida, 27% of late retransplants in both children and adults were for chronic rejection [4], and the Kyoto group reported a 35% rate of chronic rejection in a series of living donor liver transplants as a cause for primary graft loss requiring retransplantation [29]. There is a growing awareness of the role of the humoral immune response in the development of chronic rejection [30]. Recurrence is characterized by clinical deterioration, histologic features, elevated transaminases, and increased immunoglobulins. Treatment with steroids and increased immunosuppression may control disease progression, but a significant number of patients may require retransplantation [39]. Earlier arguments that suggested that alcohol recidivism would lead to poor adherence to immunosuppressive regimens and premature graft loss have also been proven false [43]. Obviously, resumption of alcohol use would be a contraindication for retransplantation and careful assessment of the psychosocial situation is necessary before approval in this patient group. Cholangiographic and biochemical evidence along with histologic findings support the diagnosis of recurrence. It was postulated that the reasons behind this were not just disease recurrence but also a high rate of biliary complications and chronic rejection. Within 1 year of the finding of recurrent cirrhosis, 40% of patients develop evidence of hepatic decompensation and less than 50% survive a year from the time of decompensation [55]. Although the surgery is technically easier, the mortality is likely high because of the poor clinical condition of the recipient [10]. This is a rapidly evolving area since the introduction of direct-acting antiviral drugs. The presence of early fibrosing cholestatic hepatitis was considered a contraindication for retransplantation by many centers. This can be a difficult task in the current system of liver allocation that provides grafts to the "sickest first. Improvements in the results of primary grafting as well as the outcome of retransplantation have been noted. Between 1999 and 2014, the 1-year primary liver transplant survival rate improved from 85. However, when all patients are included, the results with retransplantation still fall short of primary grafting [59,60]. Timing of retransplantation Several analyses have shown that timing plays an important role in the outcome of retransplantation [6,59,61,62]. It was the patients who underwent retransplantation in the period between 8 and 30 days who had a significantly worse outcome, emphasizing the need for early recognition of patients who require early retransplantation. There is a clear differential outcome between those requiring early urgent retransplantation and those who require an "elective" second graft. In some cases, patients who underwent retransplantation many months after the primary transplant exhibited survival curves similar to those receiving a single transplant. For urgent retransplantation, which likely coincides with the first 30 days Chapter 47: the Role of Retransplantation 1151 Cause of death following retransplantation the development of sepsis and multiorgan failure accounts for most of the deaths in patients undergoing retransplantation, and the largest proportion of deaths occur in the first few weeks after transplant [73]. The incidence of death secondary to sepsis is twice as high in patients undergoing retransplantation compared with those receiving just one graft, with a 50% incidence of fungal infection [64,74]. The high incidence of graft loss due to sepsis in these patients may reflect the immunosuppressed status of the patients prior to retransplantation, as well as their deteriorated functional status. In light of these findings, it may be prudent to reduce immunosuppression perioperatively and initiate more effective antimicrobial prophylaxis for patients undergoing retransplantation. Less frequent causes of death following retransplantation include technical problems such as intraoperative mortality, arterial and portal vein thrombosis, and postoperative complications such as cardiac events, neurologic complications, recurrent disease, and persistent liver failure. Models to predict survival after retransplantation the critical shortage of donor organs and the resultant prolonged patient waiting periods before transplantation have prompted many to define a mathematic model that adequately predicts survival after retransplantation. Individual patients were then stratified into low-, medium-, and high-risk groups, in an attempt to predict survival; recipient age, creatinine and bilirubin levels, and timing of transplant between 15 and 60 days were found to be predictive of outcome. Patients having four out of a possible five points had a 1-year survival of only 27%. This classification system adequately discriminated high-risk and low-survival patients in three databases to which it was applied.

A high-fat diet (45% of energy from fat) containing palm oil (44% saturated palmitic acid and 37% monounsaturated oleic acid) reduced microbial diversity and increased the Firmicutes to Bacteroidetes ratio in mice [170] research on women's health issues generic nolvadex 10 mg buy on line. There is great diversity in the metabolic actions and activity of different gut bacteria. Gut bacteria can biosynthesize a variety of molecules, including several types of vitamins. For example, Bifidobacterium and Lactobacillus can synthesize vitamin B9 (folate) [177]. Intestinal microorganisms can also biosynthesize amino acids, bile acids, short-chain and long-chain fatty acids, all of which may affect host metabolism and physiological processes. Microbial transformation of dietary components with the production of bioactive compounds. Importantly, the host malnutrition, particularly low micronutrient supply, may affect microbiota development, composition, and metabolism [179]. The data from the preclinical experimental studies using germ-free animal models demonstrated that mice lacking gut microbiota are resistant to diet-induced obesity, liver steatosis, and insulin resistance [180,181]. In mice fed a high-fat diet, the relative abundance of Firmicutes was positively correlated with liver triacylglycerol levels and negatively correlated with hepatic expression of miR-666 and miR-21 [187]. The alterations in the gut microbiome, specifically lower abundance of Bacteriodetes and higher levels of Proteobacteria, were associated with endotoxemia in people with alcoholism [193]. Restoration of alcohol-mediated alterations in the gut microbiome by oral supplementation with probiotics was associated with improvement in liver injury in patients with mild alcohol-induced liver injury admitted to an alcohol detoxification unit [199]. In comparison, mice fed ethanol plus unsaturated fat diet (rich in oleic and linoleic acids) developed microbial dysbiosis which was characterized by reduced proportion of Firmicutes, increased Bacteriodetes, and a reduced Lactobacillus population [86]. Recent studies demonstrated that ethanol and unsaturated fat diet (rich in linoleic acid) but not ethanol and saturated fat diet (rich in medium-chain fatty acids) caused a decline in the abundance of both Bacteriodetes and Firmicutes phyla, with a proportional increase in the Gram-negative Proteobacteria and Grampositive Actinobacteria phyla; these events were associated with disruption of the intestinal barrier, endotoxemia, liver steatosis, and hepatic and intestinal inflammation and injury [96,195]. The ethanol and unsaturated fat diet-induced microbial dysbiosis was associated with noticeable changes in the fecal metabolites, specifically low levels of octanoic acid, which possesses some antibacterial properties, and butanoic acid, which is an energy source for the intestinal epithelia and serves as a potent histone deacetylase inhibitor. The authors demonstrated that mice seeded with the intestinal microbiota from a patient with severe alcoholic hepatitis developed more severe alcohol-induced liver damage [201]. Another study demonstrated that the fecal microbiota transferred from the "control-resistant" mice protected recipient mice from alcohol-induced depletion of Bacteroidetes, and prevented alcohol-induced hepatic steatosis and injury [202]. A critical unanswered question is whether altering nutrition can favorably impact the microbiome and prevent/improve liver disease in humans. Nutritional recommendations Inpatient/intensive care unit patients Recent studies suggest that patients at high risk for malnutrition are more likely to benefit from early enteral nutrition, as indicated by reduced infections and other complications and even reduced mortality compared to patients at low risk for malnutrition [205,206]. Patients with liver disease (especially those with cirrhosis) are at high risk for malnutrition during hospitalization. Multiple professional societies have established guidelines related to nutritional assessment and nutritional support for patients with liver disease. It is important to rapidly assess for electrolyte disturbances as these may be life-threatening. Electrolyte imbalance in cirrhosis usually involves abnormalities in sodium and/or potassium concentrations. This usually occurs with normal or increased amounts of sodium being offset by greater increases in total water volume. Many factors contribute to decreased sodium concentrations, with two of the most important being impaired free water clearance and the use of diuretics. In patients with decompensated liver disease, the main way of treating hyponatremia is fluid restriction. Hypernatremia occurs much less frequently in liver disease, and it is usually due to medical interventions with diuretics or lactulose therapy. Hypokalemia may occur as a result of poor nutrition, or due to vomiting, diarrhea, or use of diuretics. Hypokalemia can produce a spectrum of consequences ranging from muscular weakness to cardiac arrhythmias. Hyperkalemia is less commonly observed in liver disease and usually accompanies renal failure or use of potassium-sparing diuretics. It is critically important that patients are not placed on potassium-containing salt substitutes while on potassium-sparing diuretics. For the patient who has been actively drinking alcohol, it is useful first to correct electrolyte imbalances and to treat and control withdrawal symptoms when present. This will facilitate control of electrolyte disorders and decrease the risk of having a feeding tube or parenteral nutrition line pulled out. When patients are discharged home, it is important to rediscuss the potentially toxic interactions between potassiumcontaining salt substitutes and potassium-sparing diuretics, such as spironolactone. This concept should optimally be reinforced both verbally and with nutrition education handouts. The use of oral nutrition supplements, including a nighttime snack, is encouraged in patients able to consume projected energy requirements by the oral route. It is important to monitor food intake because of the high risk for malnutrition, which may be underestimated.

Induction therapy with high-dose steroids is initiated intraoperatively womens health 15 minute workouts nolvadex 20 mg order visa, and then slowly tapered off. On the other hand, vaccination is not sufficiently effective in patients with cirrhosis [31]. Careful and thorough patient and caregiver education by transplant coordinators and physicians should be clearly addressed. Daily performance of liver function tests is used for surveillance of proper engraftment. Serum albumin is a good index of graft synthetic function but not in the immediate posttransplant period, because of its prolonged half-life and unstable fluid shifts. However, changes in hepatic biochemical tests are nonspecific and reflect injury from any cause making liver biopsy essential for accurate diagnosis. Reported rates of rejection vary because of differences in reasons for a liver biopsy, such as a biopsy triggered by abnormal liver function tests or done routinely as per transplant center protocol. The clinical significance of these findings remains unclear; however, most of the transplant centers performing protocol biopsies may treat rejection based solely on histology [37,38]. Venous endothelium and biliary ducts are the targets of the inflammatory reaction [39,40] (Tables 43. This core needle biopsy specimen shows a portal inflammatory infiltrate containing lymphocytes (predominantly), eosinophils, and neutrophils. Endotheliitis characterized by subendothelial localization of the inflammatory cells in a portal vein branch (arrowhead) and bile duct inflammation/damage (arrows) can also be seen. More severe episodes require corticosteroids pulse therapy and recycle, and in steroid-refractory cases, antilymphocyte preparations or monoclonal antibodies. Distinction between these two entities is essential, because the use of antirejection therapy, especially corticosteroids, might accelerate allograft hepatitis and result in poorer long-term outcomes. Structure Small bile ducts (<60 m) Early chronic rejection Degenerative changes involving a majority of ducts: eosinophilic transformation of the cytoplasm; increased N: C ratio; nuclear hyperchromasia; uneven nuclear spacing; ducts only partially lined by biliary epithelial cells Bile duct loss in <50% of portal tracts Intimal/luminal inflammation Lytic zone 3 necrosis and inflammation Mild perivenular fibrosis Occasional loss involving <25% of portal tracts So-called "transition" hepatitis with spotty necrosis of hepatocytes Intimal inflammation, focal foam cell deposition without luminal compromise Inflammation damage and focal foam cell deposition Late chronic rejection Degenerative changes in remaining bile ducts Loss in 50% of portal tracts Terminal hepatic venules and zone 3 hepatocytes Portal tract hepatic arterioles Other Large perihilar hepatic artery branches Large perihilar bile ducts Focal obliteration Variable inflammation Severe (bridging) fibrosis Loss involving >25% of portal tracts Sinusoidal foam cell accumulation; marked cholestasis Luminal narrowing by subintimal foam cells Fibrointimal proliferation Mural fibrosis N: C ratio, nuclear to cytoplasmic ratio. If large-volume ascites persists, other causes, such as venous outflow anastomosis obstruction, should be considered. Nowadays, with the piggyback technique, caval obstruction is rare and outflow obstruction usually results from suprahepatic anastomoses, manifesting as acute outflow obstruction with coagulopathy, jaundice, and ascites. Late presentation of hepatic outflow obstruction manifests as hepatomegaly and persistent ascites resistant to medical therapy. Diagnosis can be made with Doppler ultrasonography in some cases, but hepatic venography and assessment of a gradient between the pre- and postanastomotic site remains the gold standard. Findings on liver biopsy include central lobular congestion and necrosis with cholestasis and absence of other features of rejection. Management of outflow obstruction is dictated by the severity of allograft dysfunction and timing of presentation. Chronic outflow obstruction with preservation of the graft function can be handled conservatively with diuretics. However, radiologic revision of outflow anastomoses followed by venous stenting or angioplasty of the obstruction might be required. During this phase of hospitalization, many patients develop a variable degree of psychiatric or neurological abnormalities. Anxiety and psychosis with delusions and hallucinations are frequent, but most resolve gradually without any specific therapy. Seizures, encephalopathy, and tremors are not uncommon at this stage; they are usually multifactorial in origin. In the setting of thrombocytopenia and coagulopathy, intracerebral hemorrhage or subdural hematoma may occur spontaneously. Patients transplanted for acute liver failure present a higher risk of neurological complications. These patients usually present with cerebral edema, and in those cases where an intracranial pressure monitor is in place, careful intraoperative monitoring is warranted to reduce the risk of pre- and posttransplant neurological complications. Several other medical complications can occur during the course of hospitalization. These can be exacerbations of preexisting conditions, but more often are side effects of the immunosuppressive drugs (Table 43. In the absence of toxic immunosuppressant drug levels, lifestyle modifications, including weight loss, physical activity, and dietary sodium restriction are advised. When a second agent is required, -blockers such as atenolol can be added, but generally are less effective than amlodipine. Corticosteroid withdrawal and switching from tacrolimus to the less diabetogenic drug cyclosporine may be helpful [49]. Lifestyle modifications and diet, oral hypoglycemic agents and/or insulin administration might be necessary. In patients with renal dysfunction metformin is to be avoided because of the potential risk of developing lactic acidosis [46]. Liver biopsy findings include microabscesses, lobular hepatitis, and giant cells with viral inclusions. Another important objective while the patient is still in the transplant unit is education of the recipient and caregiver with respect to administration of medications over the long term, and also proper health care practices. A member of the transplantation team should spend time instructing the patient and family about medication side effects, signs and symptoms of infection, rejection, diet, and general rules of medical care. Patients should also be instructed on the care of surgical wound, T tube, if one is placed, and any drains that remain. This time can also be used to emphasize the importance of communication with the liver transplant center regarding unexpected clinical situations that may occur at home.

The main cause of death in these patients is not ongoing pregnancy zumba dvd purchase generic nolvadex, uncontrolled variceal bleeding, but additional complications that occur during the bleeding episode leading to a further deterioration in liver or kidney function [169,171]. The immediate goal of therapy in these patients is to control bleeding, to prevent early recurrence (within 5 days), and to prevent 6-week mortality, which is considered, by consensus, the main treatment outcome [76]. Short-term prognosis is excellent in patients with otherwise compensated cirrhosis whose only complication is variceal hemorrhage. On the other hand, when variceal hemorrhage presents in a patient with other complications of cirrhosis, such as ascites and/or kidney dysfunction, the short-term mortality is high. Initial management includes adequate volume replacement, a conservative blood transfusion strategy, and antibiotic prophylaxis. Vasoactive agents (octreotide, terlipressin, or somatostatin) should be initiated on admission, before diagnostic endoscopy. After initial volume replacement, blood transfusion strategy should be conservative. Transfusion/volume expansion in the individual patient should take into account other factors such as age, cardiovascular disorders, ongoing hemorrhage, and hemodynamic status. Patients with gastrointestinal hemorrhage are at a high risk of developing bacterial infections and it has been shown that antibiotic prophylaxis leads to a decrease in the development of infections, recurrent hemorrhage, and death [176,177]. Regarding the type of antibiotic, intravenous ceftriaxone has been shown to be more effective in preventing infection compared to oral norfloxacin [180], however most of the difference was explained by a high rate of infections by quinolone-resistant organisms. The specific antibiotic recommended should be based on individual patient risk characteristics and local antimicrobial susceptibility patterns, with ceftriaxone (1 g/24 h) being the first choice in patients with advanced cirrhosis, in those on quinolone prophylaxis, and in hospital settings with high prevalence of quinolone-resistant bacterial infections [76]. Norfloxacin is no longer available in the United States and is not available in most inpatient formularies. All vasoactive drugs used in the control of acute hemorrhage are used in intravenous infusion. A recent study comparing the three most utilized worldwide (somatostatin, octreotide, terlipressin) found no significant differences among them [182]. Ideally, endoscopy should be performed within 12 hours of admission, following hemodynamic Chapter 12: Management of Portal Hypertension Table 12. The diagnosis of variceal hemorrhage is considered certain when active bleeding from a varix is observed or when a sign of recent bleeding such as a "white nipple" is observed. Variceal hemorrhage should also be diagnosed when varices are the only lesion found and blood is present in the stomach or endoscopy is performed after 24 hours of hemorrhage. Balloon tamponade is associated with a high rate of severe adverse events, especially in units with lack of experience, and should be kept in place for a maximum of 24 hours. Endoscopically placed self-expandable metal stents may be more effective and safer than balloon tamponade in refractory esophageal variceal bleeding, and can be maintained for up to 7 days, thus facilitating the correction of comorbidities [187]. Patients recovering from a recent variceal hemorrhage In previous editions of this book this was described as "secondary prophylaxis of variceal hemorrhage. Prevention and management of other complications of cirrhosis are discussed in different chapters of this book. Patients who recover from the first episode of variceal hemorrhage have a high rebleeding risk (60% in the first year), with a mortality of up to 33%. Therapy to prevent rebleeding is therefore mandatory in these patients and should be instituted before hospital discharge. However, the confidence intervals were too wide to infer noninferiority of drug therapy alone as compared to combination therapy. This improvement in survival was mainly related to a decrease in deaths from bleeding or infections [191]. In patients with severe liver dysfunction there was a higher than expected incidence of rhabdomyolysis. Further confirmatory trials are needed before simvastatin can be recommended for this indication. In patients with indication for statins for prevention of cardiovascular events, these should be continued with careful monitoring for side effects and dose adjustment. Management of the episode of acute hemorrhage from gastric varices the initial management of the patient with a gastric variceal hemorrhage is similar to that of esophageal variceal hemorrhage (volume resuscitation, vasoactive drugs, and antibiotics). The role of vasoactive drugs has never been specifically investigated, but these are started empirically in patients with cirrhosis and upper gastrointestinal bleeding prior to diagnostic endoscopy, and it is reasonable to maintain vasoconstrictor infusion after the diagnosis of bleeding from gastric varices is confirmed endoscopically. Management of gastric varices Gastric varices are present in about 20% of patients with cirrhosis. Large size (>10 mm in diameter), presence of red spots, and severity of liver dysfunction [86,192] are also associated with an increased risk of bleeding. In the management of gastric variceal hemorrhage, there is much less evidence available compared to management of esophageal varices. Only a few controlled clinical trials have been performed, with a small sample size and, in many cases, without adequate stratification according to the type of gastric varices. Endoscopic therapy Cyanoacrylate injection has been compared with variceal ligation in three randomized trials. It frequently requires additional embolization of spontaneous shunts feeding the varices. However, the use of cyanoacrylate should be limited to centers with wide experience with the technique.

Transplant recipients subsequently have a normal donor phenotype with respect to copper metabolism, and with rare exception, they do not require further therapy specific to Wilson disease. Pharmacologic treatments for Wilson disease include chelating agents and zinc salts (Table 29. Zinc salts act mainly by blocking the intestinal absorption of dietary copper, but also stimulate the biosynthesis of endogenous chelators in the liver, such as metallothioneins, that help detoxify the remaining metal [43]. The treatment of asymptomatic patients and maintenance therapy for previously symptomatic patients are identical (Table 29. Patients with hepatic insufficiency or chronic active hepatitis evident only on biochemical testing or histologic examination of the liver should be considered symptomatic, and treated with chelation therapy for adequate copper removal before their medications are changed or the doses of chelator reduced for maintenance therapy (see subsequent text). The largest experience for long-term treatment is still with penicillamine, whereas trientine and zinc salts are alternative agents with fewer potential side effects. Both these alternative agents, previously used only for penicillamine-intolerant patients, should now be considered for the initial therapy of asymptomatic patients and for long-term use as maintenance therapy. Regardless of the specific agent chosen, monitoring for efficacy and patient compliance is crucial. Chelation therapy is indicated as the primary therapy for symptomatic patients with hepatic or neurologic/ Table 29. As mentioned in the preceding text, the greatest experience thus far is with penicillamine. Whether this worsening would have occurred with the use of alternative agents is uncertain and awaits the systematic evaluation of alternative agents as the primary treatment for neurologically affected patients. Zinc salts may be used as an alternative initial therapy for patients who cannot tolerate penicillamine or trientine. Although it has been reported that zinc is an effective treatment for symptomatic patients, it may be delayed in its effective onset of action and therefore chelation agents are preferable in this setting. There may be a role for therapy with both zinc and chelation (temporally separated) based on their separate modes of action, but there have been no studies that have compared combination therapy to either chelation or zinc alone [88]. Tetrathiomolybdate, first used to treat animals with copper toxicosis, is currently an experimental agent undergoing evaluation as an initial treatment for patients with Wilson disease, in particular for patients with neurologic symptoms. However, studies directly comparing the efficacy of this agent with trientine did not show statistically significant differences in neurologic and speech scores over a 4-year observation period [90]. The current studies of the more stable form of tetrathiomolybdate for initial treatment of Wilson disease should yield more information on the safety and utility of this agent. This drug, when used in conjunction with oral therapy with penicillamine or trientine, was administered intramuscularly in an oil base. The dietary consumption of foods with a high copper content should be avoided during the initial phases of treatment. These include organ meats such as liver, in addition to nuts, shellfish, and chocolate. In this last report, acute renal insufficiency was observed more often in patients who underwent transplantation for acute liver failure secondary to Wilson disease than in those who underwent transplantation for acute liver failure of other causes. During the acute phase of acute liver failure, when toxic copper complexes are being released into the circulation, plasmapheresis, exchange transfusion, and albumin dialysis have been utilized in an effort to further reduce copper-induced toxicity. However, it is our opinion that transplantation should not be used for patients with neurologic symptoms in the absence of hepatic failure, especially given the current shortage of donor organs. Living donor transplantation has been performed for acute liver failure secondary to Wilson disease in a few children and in some adults as well. Partial grafts from heterozygous parents were successful, with good organ function in both donor and recipient [96]. The treatment of pregnant women and patients with Wilson disease who must undergo surgical interventions deserves special mention. The goal of treatment in pregnancy is to reduce the risk for teratogenicity while maintaining adequate disease control in the mother, reduce her risk for bleeding, and prevent interference with wound healing. For patients being maintained on chelation therapy, the dosage of penicillamine or trientine should be lowered whenever possible early in the course of the pregnancy. The suggested dosage is 500 mg/day, and close monitoring during each trimester is advised. Zinc therapy can be maintained uninterrupted at full dosage during pregnancy and postpartum [100]. When patients with Wilson disease maintained on chelating agents must undergo surgery, the dose of their medication should be reduced preoperatively and perioperatively to avoid interference with wound healing by impaired collagen cross-linking due to copper depletion in lysyl oxidase. No adjustment of the dosage is required for patients on zinc therapy, either perioperatively or postoperatively.
