In the earliest days of transplantation, clinical outcomes were marred by fatal complications related to ischemia, preservation injury, surgical technique, and infection. Moreover, tackling rejection was not yet part of the transplant paradigm, and organs that did survive were eventually ruined by rejection. Despite the first successful transplantation of kidneys between identical twins, theoretical immunologists and other naysayers predicted devastating consequences of transplantation between individuals who were not genetically identical. Early work in immunosuppression began changing the landscape of clinical transplantation. Surgeons started to transplant successfully and consistently between unrelated individuals. With these improvements the notion of halting or even reversing the rejection process came to the fore. Notable advances were achieved in the area of pharmacological modulation of the immune system. Immunosuppression, at first akin to an unwieldy hammer, became more precise and directed at specific steps in the immunological process. The advent of less toxic medications, such as cyclosporine and later tacrolimus, revolutionized transplantation of all organs. Concurrently, the side effects of these medications, often apparent only after long-term use, were tempered, and new, less toxic immunosuppressive protocols were devised. With these discoveries, liver transplantation, once an experimental modality, became the accepted standard of care for most patients suffering from end-stage liver disease. As a consequence, there continue to be new research and developments in the treatment of rejection. Like many of the early once-fatal complications, the diagnosis of rejection has become less devastating and significantly less ominous. In the quotidian life of the long-term liver transplant patient, morbidity from the chronic use of immunosuppressive agents has surpassed rejection as the major concern. This inflammation initially affects the biliary epithelium and subsequently the hepatocytes. Histological examination of liver tissue reveals a mixed cellular infiltrate composed predominantly of lymphocytes localized to the portal tracts and the central vein areas. Early histological changes, however, are often nonspecific and may be confused with recurrent hepatitis C infection. With time or severity, damage to bile ducts and to the central vein endothelium occurs. This difference may be due to the protective mechanisms and regenerative capabilities of the liver. Patients who receive combined grafts consisting of a liver with any other organ tend to have lower rates of all forms of rejection. Experimental hepatic tolerance was first recognized in 1965 when liver grafts transplanted between outbred pigs survived without immunosuppression. In humans there have been anecdotal reports of tolerance developing in transplanted patients who were weaned from, or noncompliant with, immunosuppressive therapy. These biochemical changes almost always occur before clinical signs and symptoms and are a manifestation of the cholestatic inflammation first affecting the biliary epithelium and subsequently the hepatocytes. Accordingly, subtle increases can first be seen in bilirubin, alkaline phosphatase, and -glutamyltransferase levels. Although no absolute biochemical parameters can currently be used to define an episode of rejection, there are some experimental methods currently being evaluated. Clinical findings tend to appear later in the course of rejection and reflect more significant injury to the graft. These signs and symptoms can include fatigue, fever, malaise, abdominal pain, decreased bile output, increasing ascites, and hepatomegaly Table 93-1). Other complications include pneumothorax, hemobilia, peritonitis, perforated viscus, and the development of an arteriovenous fistula. The risk for sustaining any of these complications is about 2%, and the risk for death hovers between 0. Protocol biopsies in the postoperative period are advocated in some centers as a way to treat rejection more effectively. Although no multicenter randomized controlled trial has ever been conducted, some centers treat based on histological criteria without biochemical evidence of graft dysfunction. These preemptive efforts have not been conclusively shown to be beneficial in liver transplant patients. Recent data suggest that this approach may be overly cautious and may lead to overtreatment. From 15 studies of patients undergoing protocol biopsies, 302 patients were identified who had histological, but no biochemical evidence of rejection. Although the smaller bore of the fine needle may result in less trauma, this risk may be amplified by the need to perform multiple passes because insufficient quantity of tissue may be obtained with a single pass. Initially used in cardiac transplantation, it has recently been studied in liver recipients. Thus, despite numerous attempts to use noninvasive techniques over the past 20 years, none of these diagnostic methods have been validated or meet the sensitivity and specificity of percutaneous liver biopsy. Once treatment has started, every effort should be made to also eliminate or decrease potentially aggravating factors Table 93-3). Such treatment is associated with a constellation of potential toxicities, including a risk for excessive immunosuppression and infection. For patients being treated with cyclosporine-based immunosuppressive regimens, changing maintenance therapy to tacrolimus may also help treat and decrease the incidence of acute and chronic rejection. Corticosteroids were first used clinically for transplantation of renal allografts during the early 1960s. For many years, corticosteroids remained a mainstay of immunosuppressive therapy and ceded their major role only when calcineurin inhibitors were accepted into regular clinical practice in the mid-1980s. Over the past 4 decades the panoply of complications related to longterm use has led most transplant centers to use them sparingly. Corticosteroids are 21-carbon steroid hormones derived from the metabolism of cholesterol, and their efficacy is dependent on the presence of a hydroxyl group on carbon 11. The upregulated proteins that result from steroid binding are responsible for many of the antiinflammatory effects. Among the many immunosuppressive effects of corticosteroids: phagocytosis by neutrophils and monocytes is inhibited and disruption of T-cell activation occurs. No consensus has been reached on the optimal form, dosage, or length of treatment with corticosteroids. Trials have been conducted to compare different protocols of steroid therapy, and unfortunately, it is difficult to extrapolate general conclusions from these small and heterogeneous reports. The half-life should be long enough to afford reversal of the rejection process but not so long that long-term steroid side effects are introduced. Finally, the steroid should have as little mineralocorticoid effect as possible to avoid sodium retention, weight gain, and hypertension. Intravenous steroid administration is used initially because this route of administration results in the fastest and most consistent serum levels. Usually well tolerated, this treatment protocol can be administered to outpatients, but it may be associated with increased rates of sepsis and an accelerated progression to cirrhosis in patients with hepatitis C. In patients without clinical or biochemical improvement, ongoing rejection should be suspected. A second percutaneous liver biopsy should be performed and liver histological analysis reexamined. Occasionally these patients are first treated with another course of intravenous steroid therapy, particularly if they have responded in the distant past or if there is evidence of even slight improvement. Early immunosuppression tended to have more generalized effects on the immune system. The development of antilymphocyte antibodies, however, allowed clinicians to target the immune system more selectively. The first antilymphocyte antibodies were obtained by using the serum of animals. As laboratory techniques improved, a "second generation" of more selective antilymphocyte antibodies was created, which resulted clinically in a reduction in anaphylactic-like reactions and more selective lysis. Antilymphocyte antibodies have been shown to work indirectly through complementdependent lysis of lymphoid cells. In homogeneous monoclonal antibody preparations, such activity is directed against a single surface structure on the lymphoid cells. Patients who receive multiple administrations of this antibody have a significantly increased risk for infection and malignancy. These products are often administered as daily 4-hour infusions, and the treatment duration varies from 1 to 2 weeks depending on the preparation and response. After a treatment course, antibodies may develop against the foreign proteins in these preparations. Therapy with antilymphocyte antibodies may be accompanied by significant complications. Though relatively rare, symptoms of this syndrome mimic anaphylactic reactions and range from fever to pulmonary edema and frank hypotension. Significant neutropenia or thrombocytopenia may develop from the use of antilymphocyte antibodies, particularly with less specific preparations. Antibodies against neutrophil or platelet antigens can result in white cell counts of less than 3000/L and platelet counts of less than 50,000/L. When such significant drops occur, many centers decrease the dose of the antilymphocyte antibody preparation to half until the counts rise to a less critical level. Calcineurin inhibitors have markedly improved survival in liver transplant recipients but are associated with significant renal failure. Thus minimization of calcineurin inhibitors is a new strategy being employed by many centers. They found decreased acute cellular rejection in the treatment arm versus control with no difference in recurrence of hepatitis C at 2 years. Because steroids have been implicated in hepatitis C recurrence, this strategy has been studied extensively in an effort to wean patients quickly off steroids or avoid them completely. Llado et al55 conducted a prospective randomized trial involving 198 patients after orthotopic liver transplantation, randomized to receive basiliximab, cyclosporine, and steroids or basiliximab and cyclosporine alone. At 2-year followup there were no significant differences seen in acute cellular rejection between the two groups. Despite the humanized Fc portions of these antibodies, their destruction is apparently antibody mediated. As a result of individual patient variation and disease-specific factors, some patients need to maintain higher dosage levels. Other options include changing the mainstay medication of immunosuppression from one calcineurin inhibitor to another. The most commonly performed substitution is conversion of cyclosporine to tacrolimus therapy; less frequently, patients are switched from tacrolimus to cyclosporine therapy. Potential third agents include mycophenolate mofetil, azathioprine, and rapamycin. In such desperate situations, extreme measures may be taken, including graft irradiation, the use of powerful lymphotoxic drugs, the use of exchange resins, or retransplantation. Complications Arising From Therapy Patients undergoing antirejection therapy are at increased risk for complications secondary to increased immunosuppression Table 93-6). Concomitant opportunistic infections may develop and are often difficult to diagnose given the immunosuppressed status of the patient. Treatment with corticosteroids may also lead to subsequent adrenal insufficiency; this diagnosis should be considered in any hypotensive posttransplant patient. Depression or posttraumatic stress disorder may develop in some patients, and management should include psychiatric evaluation and treatment.

On the other hand, therapies needed to prevent organ rejection may induce neurological problems in 1 out of 10 patients. The first task of physicians is to determine whether the patient is stable medically; if this is the case, then the next question is what part of the nervous system is being affected. This question may seem irritating on the surface, but in reality it is far from an academic exercise, because most of the time physicians face a global dysfunction of the brain due to systemic illness. Thus the recognition of a diffuse neurological dysfunction is relevant because almost always the treatment is medical and should target the underlying systemic problems leading to multiorgan failure. The finding of focal neurological signs, on the other hand, may indicate a primary neurological problem, such as stroke. Focal neurological signs, however, can merely indicate that an old neurological problem has been exacerbated by acute illness, which frequently happens when a person with an old stroke becomes encephalopathic, "reexpressing" the stroke. Neuroimaging is fundamental in this particular scenario to understand what is happening to the patient. If no response is elicited, it is relevant to know whether the alteration in the state of consciousness is due to diffuse brain dysfunction or a brainstem problem. At this point a crucial issue is whether the patient is receiving medications with sedation potential. If so, all sedatives can be tapered or stopped, and the examination can be repeated later. Examine the cranial nerves: To determine whether the brainstem has been compromised, one simply needs to examine the cranial nerves. If these reflexes are absent, then the patient may have a catastrophic problem involving the brainstem, such as stroke or hypoxic-ischemic encephalopathy. One important caveat is that a person who is sufficiently awake will suppress the oculocephalic reflex. Of note also is that the gag reflex is not very useful, because it is absent in many patients (older adults in particular). Perform speech testing: A seemingly alert person who is unable to speak and expresses frustration because of the difficulty is aphasic and needs prompt neuroimaging (unless there is documented history of such deficit). Difficulty articulating words is not necessarily a focal sign, because many encephalopathic patients are dysarthric. Observe spontaneous movements: the close observation of spontaneous motor behavior can help localize a lesion, even if the patient cannot cooperate with the examination. These postures can also reveal the presence of asterixis, an intermittent interruption of posture resulting in flapping of the affected limbs. Symmetrical rhythmical jerking, however subtle, should raise concern about status epilepticus. On the other hand, asymmetrical arrhythmic jerking suggests myoclonus, which is a nonspecific and more mundane accompaniment of metabolic encephalopathies. Most patients with delirium have lethargy and excess daytime sleep, although about a third may experience bouts of psychomotor agitation. Examples of these behavioral problems include restlessness and pacing, whereas typical cognitive changes include disorientation, apathy, distractibility, and losing train of thought; sensory disturbances include illusions and hallucinations. The word delirium derives from the Latin roots de ("out of") and lira ("furrow"), which conveys the idea that affected individuals are "deranged" or "out of track. Nonspecific encephalopathies complicate about 1 out of 10 of all hospital admissions,6,7 and liver patients are particularly prone to this complication. Encephalopathy affects about 20% to 50% of patients with end-stage liver disease5 and may complicate almost one third of liver transplants. The risk for encephalopathy is also increased by a history of encephalopathy before surgery or preexisting neurological problems. On the other hand, it is often speculated that some patients with delirium probably have an underlying dementing syndrome that has gone undiagnosed, in other words, that delirium can potentially represent the first symptom of dementia. Recent studies confirm the old suspicion that delirium is associated with long-term, unremitting cognitive problems11: it is not uncommon to hear families complain that a patient "was never the same" after a prolonged hospital stay. This is a common consideration in older individuals and those with a history of alcoholic liver disease.

Portoenterostomy for reconstruction of the biliary tract after liver transplantation has been reported by Langnas et al erectile dysfunction prescription pills order cheap suhagra line. Because of the restricted availability of donor organs and the increased risk of a retransplantation erectile dysfunction protocol download pdf 100 mg suhagra sale, the option of retransplantation should be reserved for patients in whom no adequate surgical reconstruction can be accomplished diabetes obesity and erectile dysfunction generic 100mg suhagra amex. Pearls and Pitfalls · Excessive preparation or application of monopolar coagulation near the recipient and donor bile duct during explantation and transplantation may lead to impaired vascular supply to both donor and recipient bile duct erectile dysfunction caused by prostate surgery generic suhagra 50mg on-line. It is considered as one of the major causes of insufficient healing of biliary anastomoses and biliary leaks erectile dysfunction medication order generic suhagra line. Moreover impotence medical definition cheap 50mg suhagra mastercard, it may cause excessive scarring around the anastomosis, representing one of the precursors of anastomotic stricture. Therefore the arterial supply to bile duct, that is, the epicholedochal plexus, which is supplied by three arteries, should be preserved. Vessels arise from arteries at the upper and lower ends of the duct and travel longitudinally with it. Angiographic embolization of hepatic artery pseudoaneurysms is indicated for hemostasis. The donor duct should be divided high enough to ensure that its length is adequately supplied by the axial supply from above, and mobilization of the duct from the periductular tissues should be kept at a minimum. Confirmation of hepatic artery patency is essential when biliary problems develop and especially important if the proximal or intrahepatic biliary tree is the site of the abnormality. Back-table perfusion of the bile duct, which is routinely performed at our center, may clear the donor biliary system from sludge and detritus, thus avoiding early intrinsic obstruction. The authors advocated additional arterial back-table perfusion as the standard technique in liver procurement. In addition, there was a trend toward lower duration of antibiotic therapy, intensive care unit stay, and hospital stay. An excessively long bile duct may kink at abdominal closure and thus creat a nidus for stricture formation. To avoid excess length of vessels and the bile duct, an abdominal bandage may be placed underneath the liver after finishing the caval anastomosis to approximate the ends of the vessels and bile duct and allow for optimal length of donor and recipient structures. Dumonceau et al201 recently published the European Society of Gastrointestinal Endoscopy clinical guideline on biliary stenting, including indications, choice of stents, and results.

The incidence of relaparotomy is higher for drainage of intra-abdominal collection or for bleeding erectile dysfunction drugs from canada generic 50mg suhagra overnight delivery. Secondary hemorrhage occurs more commonly because of the associated renal failure and the continuing postoperative need for renal replacement therapy in many of these patients impotence juicing discount suhagra 50 mg with visa. The use of heparin and other anticoagulants should be considered carefully in light of this risk. These patients have been managed with a combination of lamivudine and hepatitis B immune globulin for a period of up to 1 year after transplant. These measures have been taken to reduce the likelihood of disease recurrence, even though one patient who received no prophylaxis remained free of virus. Follow-up and Immunosuppression the postoperative recovery of liver function may differ from that observed after whole-liver transplantation. The coagulopathy may correct more slowly, particularly if the graft volume is small. The serum transaminase levels may not fall in the normal trajectory because of a contribution from the injured native liver. The diagnosis of acute rejection may be challenging, because less marked elevation of the serum transaminase levels is seen compared with whole-liver replacement (depending on the relative graft size). Diagnosis of rejection was delayed in our first patient because no abnormality of liver function was noted other than a modest elevation of serum bilirubin level, which was thought to be due solely to poor portal venous inflow. Our experience has shown that mild cases of unconjugated hyperbilirubinemia should be investigated with graft biopsy to exclude rejection. However, we believe that many of the previously observed poorly functioning grafts have been the result of low-grade venous outflow complications that evolve into small-forsize syndrome. A small number of patients have persistent cholestasis and residual portal hypertension as a result. Currently we perform these investigations at 3, 6, and 12 months after transplantation, and the decision to reduce immunosuppression is usually made at 6 months or when signs of healthy regeneration are seen on biopsy. Gradual weaning may be required to initiate low-grade graft rejection and to stimulate regrowth of the native liver. The majority of patients who survive long term can be withdrawn from their immunosuppressive therapy. However, this must be performed gradually; otherwise an episode of severe acute rejection may be precipitated and lead to graft thrombosis and loss before sufficient regeneration has occurred. The timing of immunosuppression reduction will depend on the rapidity of liver regeneration, which in turn is dependent on the cause of liver failure and the volume and function of the graft. However, the larger volume of graft transplanted in this group (right lobe) will tend to inhibit native liver regeneration. In the subacute group the regeneration is less rapid, as observed by sequential imaging. As a consequence, reduction and withdrawal of immunosuppression tends to be later. Abrupt immunosuppression withdrawal is associated with hepatic artery thrombosis, particularly in large grafts. Graft atrophy occurs with controlled immunosuppression withdrawal, and there is seldom a need to excise these grafts ("vanishing graft syndrome"). The majority of patients are young and at greatest risk for the complications of prolonged exposure to immunosuppression. This should be considered as the best option for appropriate patients with suitable grafts.

In response to this increased allograft demand, the donor pool has been expanded to use older, fattier, and more marginal donor allografts. Intensive care management of the liver transplant recipients represents an area where evidence-based approaches can have significant impacts on the costs and outcomes associated with transplantation. The efficient use of intensive care resources can have significant cost-saving benefits for a transplant program, at a time of strained financial funding. Volume Status the volume status of a liver recipient is a continually dynamic parameter throughout the perioperative and initial postoperative course, and volume status can be simultaneously affected by contrary factors such as blood loss and overload from renal dysfunction. An accurate gauge of the volume status in posttransplant patients is crucial, although debate exists as to the best way to assess intravascular volume status. The most frequently used tool for hemodynamic monitoring is the Swan-Ganz, or pulmonary artery, catheter, which measures filling pressures in the heart and pulmonary artery. Pulmonary artery catheter use is controversial, because filling pressures have been shown to not always accurately define cardiac preload. In contrast, some believe that the data derived from these pressures have little positive predictive value in guiding hemodynamic management for improving liver perfusion and determining the appropriate resuscitative efforts. The drawbacks of this catheter are that it is more expensive and can have trouble consistently calculating an accurate end-diastolic volume, because of catheter positioning and arrhythmias that alter the R wave. Successful management requires an accurate and timely assessment of these parameters using monitoring technologies. It correlates well with the thermodilution technique from pulmonary artery catheters. It allows rapid visualization of left ventricular function and determination of the left ventricular end-diastolic area index, which calculates left ventricular filling by measuring ventricular diameter and correlating it with changes in stroke volume while intravascular volume is being adjusted. Using blood products as the initial resuscitation fluid in the fresh posttransplant recipient yields the hyperoncotic benefits of this fluid, without its detrimental effects. However, these crystalloids quickly exit the intravascular space, causing third spacing and edema that can congest the sinusoids of the allograft, while also increasing intra-abdominal compartment pressure from bowel edema. Finally, colloid starch solutions such as hetastarch (Hespan) and pentastarch (Pentaspan) increase the risk for acute kidney injury and mortality11 and should be used judiciously as a fluid for resuscitation, if at all. Hypervolemia Hypervolemia occurs from overresuscitation or more commonly in recipients with renal dysfunction. Allografts with significant preservation injury or steatosis and allografts from elderly donors are especially sensitive to the sinusoidal congestion from hypervolemia. Vascular Hemodynamics Successful management of the volume status in the initial posttransplant period requires a clear understanding of the altered cardiovascular hemodynamics that exist in the pretransplant cirrhotic patient. After the transplant this systemic vasodilation and compensatory hyperdynamic state persist until the allograft begins to function and metabolize all of the excess vasodilatory Management of Volume Status and Hemodynamics in Initial Liver Allograft Recipients Immediately posttransplant, multiple factors simultaneously affect the recipient hemodynamics, and a good understanding of volume status is crucial for patient and graft survival. Both hypovolemia and hypervolemia can be detrimental to the allograft, so one must correctly identify the circumstance and direct the treatment appropriately. Hypovolemia Hypovolemia results from inadequate intraoperative resuscitation, postoperative bleeding worsened by coagulopathy, or third spacing and edema. The treatment of hypovolemia is intravascular fluid replacement using one of several options. Blood products are a useful fluid for resuscitation in the initial posttransplant setting because they stay in the intravascular space, preventing allograft edema, and also reduce the existing edema through their hyperoncotic impact. Although the literature and conventional teaching recommend minimizing transfusion of blood products in the nontransplant patient because of an increased mortality risk,7 the transplant patient represents a different population than the one studied in these trials. Although a normal person can tolerate a 25% to 30% decrease in blood volume without a change in systemic blood pressure or heart rate, the splanchnic perfusion becomes compromised after only a 10% to 15% reduction in intravascular volume. The story is complex because the typical cirrhotic patient is vasodilated, can have marked perioperative bleeding and postoperative third spacing of fluids, with an uncertain fluid resuscitation of these losses. Comorbidities such as underlying renal dysfunction, diabetes, and right heart failure can make the picture more complex. SvO2 is the percentage of oxygen in the blood that returns to the right side of the heart, and it uses blood drawn from the tip of the pulmonary artery catheter before its reoxygenation in the pulmonary capillaries. The canalicular enzymes -glutamyl transferase and alkaline phosphatase begin their rise approximately the fourth day after transplant and typically rise up to five times normal before declining. Liver Function Tests the liver has synthetic, excretory, and metabolic functions, each of which can be assessed by particular laboratory values. Albumin levels can also be used to assess synthetic function; however, its utility is limited because albumin levels are also affected by nutritional status, volume overload, and the fact albumin is a negative phase reactant. The excretory and clearance function of the liver is measured by the bilirubin level, and stratification into direct and indirect levels provides further information. The metabolic function of the liver is assessed by the serum glucose level, because the liver maintains blood glucose levels through glycogenolysis and gluconeogenesis, and very low levels of glucose refractory to treatment should raise concern about a nonfunctioning liver. The metabolic function can also be measured by lactate level, because lactate is converted to pyruvate in the liver via the Cori cycle. Debate exists as to the best approach, but options include SwanGanz catheters, pulse dye densitometry, and transesophageal echocardiography. A normal person can tolerate a 25% to 30% decrease in blood volume without a change in systemic blood pressure, but the splanchnic system becomes compromised after only a 10% to 15% reduction in intravascular volume due to vascular redistribution from the renin-angiotensin system. The clinical factors that indicate a functioning allograft include stable body temperature, improving urine output, improving mentation and wakefulness, normalization of respiratory effort, and if drains are present, a change from sanguinous/serosanguineous output to ascites. Nonetheless, despite not measuring liver function, these liver enzymes can be useful in identifying the potential for allograft problems. B, Hepatic vein assessment (outflow) for triphasic flow, which should be in the opposite direction of the hepatic artery. C, Portal vein assessment (inflow) for flow, looking for velocity changes indicative of a stenosis. The portal vein is assessed by a color Doppler scan showing hepatopetal monophasic flow that varies with respiration,19 and portal vein complications will present as a lack of color Doppler signal. In adults the portal vein luminal diameter should be greater than 25 mm, without any acceleration of flow at any points of narrowing. The duplex velocity waveform of the hepatic veins should show a vein flow velocity of greater than 10 cm/sec with a triphasic waveform (a large antegrade systolic and diastolic waveform with retrograde wave due to the backward transmission from right atrial pressure changes during the cardiac cycle). A flat waveform, with hepatic outflow velocity of less than 10 cm/sec along with dilation of the veins is associated with outflow obstruction. Knowing these comorbidities can prepare the clinician for potential complications and guide the studies and interventions required.
