The metabolic syndrome is common after liver transplant being present in approximately half of recipients. It has been associated with adverse outcomes such as progression of hepatitis C and major vascular events. As the United States population ages and the rate of obesity increases, prevention of the metabolic syndrome in the post-transplant population deserves special consideration. Currently, the metabolic syndrome after transplant appears at least two times more common than observed rates in the general population. Specific guidelines for patients after transplant does not exist, therefore prevention rests upon knowledge of risk factors and the presence of modifiable elements. The current article will focus on risk factors for the development of the metabolic syndrome after transplant, will highlight potentially modifiable factors and propose potential areas for intervention. As in the non-transplant population, behavioral choices might have a major role. Opportunities exist in this regard for health prevention studies incorporating lifestyle changes. Other factors such as the need for immunosuppression, and the changing characteristics of wait listed patients are not modifiable, but are important to know in order to identify persons at higher risk. Although immunosuppression after transplant is unavoidable, the contribution of different agents to the development of components of the metabolic syndrome is also discussed. Ultimately, an increased risk of the metabolic syndrome after transplant is likely unavoidable, however, there are many opportunities to reduce the prevalence.

Liver transplantation is a life saving and life changing procedure for patients with advanced chronic liver disease, hepatocellular carcinoma and acute liver failure. The exceptional liver transplant recipient has normal fitness[1] and can literally climb mountains[2]. However, the more typical patient has impaired fitness[3], gains weight[4-6] and develops the metabolic syndrome[7-10]. In fact, the prevalence of the posttransplant metabolic syndrome (PTMS) ranges from 44%-58%[7-10], much higher than the 23% observed in the United States population[11]. Is the high prevalence of the metabolic syndrome after liver transplant an unavoidable consequence driven by factors such as immunosuppression? Or is it a reflection of behavioral tendencies in liver transplant recipients that can be modified to prevent illness? Although a definite conclusion is not likely, data can be found to support both possibilities. After a brief overview of the scope of the problem, the current manuscript will examine the factors which contribute to the PTMS and potential means of prevention.
The National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III)[12] defined the components of the metabolic syndrome is as follows; (1) impaired fasting glucose (≥ 100 mg/dL); (2) Abdominal obesity (> 102 cm in men, > 88 cm in women); (3) hypertriglyceridemia (≥ 150 mg/dL or drug therapy for triglycerides); (4) low levels of high density lipoprotein (HDL) (< 40 mg/dL in men, < 50 mg/dL in women or drug treatment for low HDL); and (5) elevated blood pressure (≥ 130/85 mmHg or drug treatment for hypertension). The presence of 3 or more of these components defines the metabolic syndrome. Complications of advanced liver disease can confound the diagnosis of the metabolic syndrome in the pretransplant setting. The presence of ascites alters waist circumference. Vasodilation and decreased effective circulating volume found with portal hypertension results in lowered systemic blood pressure. Synthetic dysfunction observed with end stages of liver disease immediately prior to transplant can result in lowered serum glucose and lipid values. A study evaluating the metabolic syndrome prior to liver transplantation found a rate of 5.4%[10]. Pretransplant rates for hypertension were 9%-19%[8-10,13], diabetes, 10%-22%[7-10,13], dyslipidemia, 3%-43%[9,10] and obesity, 11%-38%[7,10].
Studies of the metabolic syndrome after transplant are summarized in Table 1. The rate of the metabolic syndrome may be underestimated in some reports as diabetes is substituted for impaired fasting glucose, hypertension is substituted for elevated blood pressure and body mass index (BMI) is substituted for elevated waist circumference. The presence of the metabolic syndrome after transplant was associated with more rapid progression of hepatitis C[8] and an increased rates of major vascular events[9,10]. Although no prospective data are available, it would be reasonable to expect that the metabolic syndrome might contribute to graft loss and patient death.

The transplant population has been changing with regard to indication and recipient characteristics. Hepatitis C is declining as an indication for transplant while non-alcoholic fatty liver disease (NAFLD) is increasing and the average age of transplant candidates is rising. With these changes, risk factors for the metabolic syndrome are becoming more common in liver transplant candidates and are important predictors of PTMS development. Although studies evaluating risk factors to predict PTMS are relatively small, certain factors identified were consistent across multiple series. A summary of risk factors is presented in Table 2. Obesity before transplant is a key factor in predicting the metabolic syndrome after transplant. Both pretransplant weight[9] and BMI[7,10,14] were correlated with post transplant metabolic syndrome. Not surprisingly, persons who were obese prior to transplant were often obese after transplant[7]. The rate of obesity in wait-listed patients varies by transplant indication. Persons awaiting transplant with cryptogenic cirrhosis, which often results from NAFLD, were found to be more commonly obese than age and gender matched controls[15]. NAFLD has increased annually as an indication for liver transplantation and is projected to become the most common indication for transplantation over the next 10-20 years[16,17]. Review of Scientific Registry of Transplant Recipients data showed recipients characterized as other/unknown causes, which includes NAFLD, has steadily increased in the past 10 years currently representing 23.6% of recipients, almost equaling the percentage of recipients with hepatitis C[18]. The proportion of obese persons awaiting transplant will presumably increase with the indication for transplant changing to a higher proportion of recipients with NAFLD. Compounding the effect of obesity, transplant for cryptogenic cirrhosis was found to be a risk factor for PTMS when controlling for other factors including pretransplant BMI[9,10].
Other risk factors for the PTMS have been identified. Pretransplant diabetes was found to predict PTMS in multiple series[7,10,14]. In fact, in one study, persons with pretransplant diabetes had nearly a 6 fold higher odds of having the metabolic syndrome after transplant[10]. Age was additionally predictive of the metabolic syndrome after transplant[9,10]. This is particularly important as the recipient population in the United States is aging. In 2009, nearly 75% of transplant recipients were above the age of 50, compared to 1993 where only 42% of recipients were 50 years of age or greater[18]. Other pretransplant factors that were associated with the development of the metabolic syndrome after transplant in at least one series include hypertriglyceridemia[10], low HDL[10] and transplantation for hepatitis C or alcohol cirrhosis[9].
A preventive intervention could target persons with chronic liver disease, before they require transplant. The long term benefit of weight loss in an obese patient with cirrhosis is not known. In limited series from weight loss surgery, fibrosis improvement in cirrhotic patients after weight loss was inconsistent[19-21]. However, in selected persons with compensated cirrhosis, diet and weight loss are reasonable recommendations. The potential for a weight loss intervention in reducing future need for transplant in obese persons with cirrhosis is an area in need of study. An exercise program in persons with advanced cirrhosis awaiting transplant may have additional benefits. Sarcopenia[22] and decreased functional capacity measured by a six-minute walk test[23] was associated with mortality in persons with cirrhosis. Clearly, increasing physical activity in cirrhotic patients at various degrees of synthetic dyfunction has potential utility and deserves further study.
Existing data indicate that as liver disease progresses to the point of needing transplant, participation in lifestyle modification becomes increasingly limited by malnutrition, muscle loss and reduced exercise capacity. Protein calorie malnutrition is common, and occurs more frequently with advanced liver disease[24]. In cirrhosis, a shift toward a catabolic state with utilization of stored fat as a primary energy source during rest and exercise has been observed[25,26]. The catabolic state induced by an overnight fast in a cirrhotic patient is roughly equivalent to a 36 h fast in a healthy subject[27]. In a state of protein malnutrition, there is no rationale for a calorie restricted diet in a patient that is potentially requiring transplant. Alterations in physical activity are additionally vital for clinically significant weight loss, with a recent recommendation of greater than 250 min/wk[28]. There are limitations for cirrhotic patients to achieve this goal. In health-related quality of life measures, persons awaiting liver transplant reported decreased scores relating to physical functioning[29]. Oxygen consumption during peak exercise is often severely impaired in liver transplant candidates, and is correlated with disease severity[30]. Additionally, cirrhotic patients develop anaerobic metabolism at low work loads, an effect that also becomes more pronounced as liver disease progresses[31]. Studies have shown decreased muscle mass[22] and strength[31] in cirrhotic patients which may further limit the ability to exercise. The increase in portal pressure which can occur during exercise could potentially increase the risk of complications such as variceal bleeding is another barrier to exercise[32].
As obesity prior to transplant is a risk factor for PTMS, it is intuitive that weight gain after transplant might predict the metabolic syndrome. However, data are mixed. The overall change in BMI after transplant was associated with the metabolic syndrome in one series[7] but not in another[9]. It is possible that ascites pre transplant may have resulted in the underestimation of weight gain post transplant in the later series. Weight gain after transplant is well described, however. In one series, the proportion of overweight and obese persons after transplant was 57% compared to 38% prior to transplant[7]. In a large series of almost 600 liver transplant recipients, the median weight gain at 1 years and 3 years was 5.1 kg and 9.5 kg, respectively[6]. In studies with longitudinal data, it appears that most weight gain occurs within the first year after liver transplant[5,33,34]. Data from our center echoes these findings and is shown in Figure 1[35]. Weight gain after transplant should be viewed in the context of persons returning to health after illness. Aggregate data from three studies which measured the rate of an elevated wait circumference after transplant totaled 36.9%[7,10,35]. Although the populations are not matched, the absolute number is strikingly similar to the 38.6% rate reported for the United States population[11]. In a study comparing rates of obesity, the standard prevalence ratio was not significantly higher in persons after liver transplant compared to the general United States population[36].
Despite the weight gain over time after transplant, time since transplant was not associated with the prevalence of PTMS[7,9,10]. This finding suggests factors resulting in PTMS develop soon after transplant and factors in addition to obesity require further scrutiny. Immunosuppression is one such factor. The overall contribution of immunosuppression to the development of the metabolic syndrome after transplant is difficult to measure, since immunosuppression is unavoidable. Although, the choice of calcineurin inhibitor (CNI) was not associated with the development of the metabolic syndrome[7,8], different immunosuppressive agents have been shown to increase risk for various components of the metabolic syndrome. With regard to weight gain after transplant, one series found more weight gain with cyclosporine in the first year[6]. However, the effect was not seen at 2 years. Another series found a higher overall BMI in cyclosporine treated patients, but no difference in rates of elevated waist circumference[7]. Weight loss occurred in a majority of liver transplant recipients after switching to tacrolimus from cyclosporine[37]. Although corticosteroids are often associated with weight gain, this effect after transplant was found in some[5,38], but not all series[6,34].
When compared to the general population, a higher prevalence of posttransplant diabetes mellitus (PTDM) has been observed in liver transplant recipients[36]. Much of this risk can be related to immunosuppression with both calcineurin inhibitors and steroids playing a major role. Both CNIs have been associated with decreased insulin sensitivity and reduced insulin release[39]. The reduced insulin release might result from CNI induced damage to pancreatic beta cells[40]. Comparing the CNIs, most studies show higher rates of PTDM with tacrolimus use compared to cyclosporine[41-46]. New onset PTDM was found in 27% of recipients on tacrolimus compared to 22% on cyclosporine [hazard ratio (HR) 1.24, 95% confidence interval: 1.07-1.43] in an analysis of over 15 000 recipients from United Network for Organ Sharing data[45]. Switching tacrolimus to cyclosporine was found to improve PTDM[47]. However, the absolute rates may not tell the entire story. Lowered serum levels of tacrolimus were associated with better glycemic control[48]. Corticosteroid use with CNIs has an influence on PTDM rate. Corticosteroid use increases the risk of diabetes through decreasing insulin production and peripheral sensitivity and increasing hepatic gluconeogenesis[49]. Avoidance of corticosteroids and the use of induction therapy played an important role in decreasing rates of PTDM[45,50-57]. In steroid free regimens using tacrolimus and an induction agent, PTDM was seen in less than 10% of recipients[50,53]. Other series showed that patients receiving cyclosporine are more likely to require corticosteroids[38,58]. Tacrolimus was associated with less graft loss and rejection[43] potentially lessening the need for concomitant immunosuppressive agents such as steroids. Further studies are needed to compare rates of PTDM between the two CNIs used with induction therapy.
There are multiple studies examining risk factors in addition to immunosuppression for PTDM. Impaired glucose tolerance prior to transplant consisting of abnormal glucose levels[59,60] or pretransplant diabetes[7,44,61], was shown to be associated with post transplant diabetes. Hepatitis C as the transplant indication was linked to higher rates of PTDM in multiple series[7,41,45,60-63]. Furthermore, eradication of hepatitis C led to improved glycemic control[62]. In addition to hepatitis C, alcohol cirrhosis was additionally associated with PTDM[7,44]. The number of episodes of acute cellular rejection[64,65] and the number of steroid boluses[62] were tied to higher rates of PTDM. Other factors correlated with PTDM include male gender[44,61,66], older age[41,45,67], African American race[45] and a BMI > 25 kg/m2[45,60]. Donor factors including age and diabetes were additional risk factors for PTDM[45]. Insulin resistance after transplant was associated with a pretransplant BMI > 30 kg/m2, older age, increased triglycerides, HCV infection and steroid boluses[10].
Hypertension is another metabolic component with a higher standardized prevalence ratio in liver transplant recipients compared to the general population[36]. Immunosuppression appears to have a profound effect in this setting. CNIs are known to increase sympathetic tone, result in vasoconstriction and cause sodium dependent volume expansion[68]. Hypertension was observed less often with tacrolimus than with cyclosporine[37,38,56,58,69]. Additionally, changing CNIs from cyclosporine to tacrolimus resulted in decreased rates of hypertension[70,71]. Hypertension is observed with corticosteroid use[49]. However, decreasing rates of hypertension with steroid sparing immunosuppression regimens were seen in a series using cyclosporine[54,57] but not observed in series using tacrolimus[50,51].
Unlike diabetes and hypertension, the rate of hyperlipidemia was not found to be higher in persons after liver transplant compared to the general population[36]. The definition of hyperlipidemia varied widely in studies and few used NCEP-ATP III definitions for dyslipidemia. This is important as one study found the rate of hypertriglyceridemia to be higher than that of elevated cholesterol after transplant[72]. Although the absolute rate of hyperlipidemia after transplant may not be elevated compared to the general population, various risk factors and choice of immunosuppressive agent may influence the prevalence of hyperlipidemia. Pretransplant hepatocellular disease and posttransplant renal dysfunction were found to be associated with hypertriglyceridemia after transplant[72]. With regard to immunosuppressive agent, cyclosporine was associated with more hyperlipidemia[38,56,69,73,74] and hypertriglyceridemia[38] compared to tacrolimus. Additionally, changing from cyclosporine to tacrolimus improved hyperlipidemia in multiple series[37,70,71]. The reason for this effect with cyclosporine could be related to inhibition of bile salt synthesis resulting in hyperlipidemia[75]. Long term corticosteroid use may additionally contribute to hyperlipidemia[57,76]. Steroid free or sparing regimens were associated with improved lipid levels[52,53], including less hypertriglyceridemia in one series[51]. Sirolimus, an agent used either in conjunction or in place of a CNI, is associated with high rates of dyslipidemia. With sirolimus, dyslipidemia was observed in 55% of patients, the majority of which required therapy[77]. This finding observed with sirolimus use might result from changes in insulin signaling pathways resulting in excess triglyceride production and secretion[78]. Rates of dyslipidemia were less when sirolimus was combined with tacrolimus compared to cyclosporine[79].
In summary, it appears that higher rates of the metabolic syndrome after transplant compared to the general population might be attributed to increased rates of PTDM and hypertension. Although obesity does not appear more prevalent in post transplant populations, weight gain after transplant is pervasive. These findings could lead to a two-fold plan to reduce the metabolic syndrome after transplant. The first would be prevention of excess weight gain through behavioral changes that could start before transplant and continue afterward. The second would be focusing on immunosuppressive strategies to lower rates of diabetes, hypertension and hyperlipidemia after transplant, especially in persons with multiple risk factors present prior to transplant.
After transplant, patients have an improved functional capacity and can perform tasks independently[80]. The use of a structured exercise program increased exercise capacity and fitness for the first six months after transplant followed by a plateau[81]. The improvement in fitness was three times greater than expected in a sedentary person undergoing a similar training regimen. Multiple studies have shown that although exercise performance improved after transplant, it remained lower than predicted values for age matched controls[3,81,82]. Despite the improvement in fitness and quality of life, many persons after transplant remain sedentary[81,83]. Only a quarter of persons were found to be physically active after transplant, and those that were physically active had less hypertension and decreased BMI[83]. Clearly there is a role for programs dedicated to increase physical activity after transplant. There are little data regarding nutritional composition and caloric intake after transplantation. Up to two thirds of subjects were found to have more than recommended energy intake[84]. Overall, more data is required to assess the contribution of caloric intake to weight gain after transplant.
There is very limited data regarding behavioral changes and exercise therapy after liver transplantation. A single randomized trial evaluated the effects of exercise and dietary counseling after transplantation. An improvement in cardiorespiratory fitness and quality of life was reported in the intervention group, but no changes were noted in body composition or muscle strength[82]. There was a trend toward improved body composition in the 37% of subjects that adhered to the intervention[82]. There are no data regarding the impact of an exercise program on the prevalence of the metabolic syndrome or singular components after transplant. Behavioral therapy after transplant represents an area with vast potential for important research. It is additionally important to note that the primary goal of intervention in this setting should be the prevention of weight gain immediately after transplant as opposed to the treatment of the metabolic syndrome once present.
Additional therapies for weight loss have been tried after transplant. A study using orlistat found a reduction in waist circumference, but not body mass index in a small group of patients[85]. Concern over interference with the absorption of immunosuppression limited the use of this agent. Bariatric surgery at the time of transplant and in the post transplant period was described in case reports[86,87]. However, bariatric surgery should be done in a way that preserves access to the biliary system and to minimize interference with the absorption of immunosuppression. As a result of these obvious pitfalls, bariatric surgery during and after liver transplant has not been widely performed.
The transplant population is aging and, consistent with the overall population, becoming more often overweight or obese. Immunosuppression likely contributes to an increased prevalence of the metabolic syndrome in liver transplant recipients, especially through increased rates of diabetes and hypertension. These features make it likely that the metabolic syndrome after transplant will become more prevalent. A number of preventative measures could be considered to reduce the burden of the metabolic syndrome in liver transplant recipients.
Patients should be screened for risk factors for post transplant metabolic syndrome at the time of transplant evaluation. Consistent risk factors include diabetes, obesity and cirrhosis from NAFLD. When assessing obesity, screening for the highest lifetime BMI may be beneficial. Identification of at risk patients will allow special focus on preventive effort after transplant.
Although there are no data supporting a definitive increase in risk resulting from the choice in calcineurin inhibitor, immunosuppression is modifiable. Minimization of corticosteroid use, possibly in conjunction with induction agents, appears to be beneficial in reducing components of the metabolic syndrome. The choice of CNI could be individualized based on the presence of components of the metabolic syndrome prior to transplant. For example, tacrolimus may be a better agent for someone with long standing pretransplant hypertension.
Consideration should be given for early eradication of hepatitis C, especially in those persons at risk for posttransplant diabetes.
Preventative efforts through behavioral changes should be made before and after transplant. At minimum, improved fitness prior to transplant is associated with better survival. After transplant, a multidisciplinary approach with increased activity, diet modifications and behavioral therapy should be explored. Since the metabolic syndrome develops early after transplant, intervention should begin as soon as medically feasible.
