TREATMENT OF CIRRHOSIS OF THE LIVER BY A NUTRITIOUS DIET AND SUPPLEMENTS RICH IN VITAMIN B COMPLEX

Nutritional Assessment in Inpatients With Cirrhosis Can Be Improved After Training and Is Associated With Lower Readmissions

Malnutrition is widely prevalent in cirrhosis patients, which can worsen sarcopenia, hepatic encephalopathy (HE), and overall prognosis. We aimed to define the frequency of nutritional assessments of patients with cirrhosis in retrospective and prospective (after educational training) cohorts and to evaluate prospective changes along with their effects on 90-day readmissions. This study was conducted in 2 phases. Retrospectively, records of hospitalized patients with cirrhosis from the university and Veterans Affairs Medical Center (VAMC) settings were reviewed to assess nutritional status, if a nutrition consultation occurred, the number of days patients were nil per os (npo) and received inadequate nutrition, and if nutritional management was guideline directed. In the prospective phase, after dedicated educational efforts directed at the stakeholders regarding nutritional guidelines for patients with cirrhosis, subsequently hospitalized cirrhosis patients had nutritional and 90-day readmission data collected for comparison between groups. In total, 279 patients were included in the retrospective phase (150 university/129 VAMC), and 102 VAMC patients were in the prospective phase. Cirrhosis severity, reason for admission, and hospital course were similar between groups regardless of cohort, ie, prospective versus retrospective or VAMC versus university. The prospective group had significantly more nutritional consultations and assessments (74.5% versus 40.1%; P < 0.001) compared with the retrospective group regardless of comparisons between the VAMC and university cohorts. Both groups had a similar number of days npo, but the prospective group had fewer days of inadequate nutrition. The 90-day readmission rate was significantly lower in the prospective group versus the retrospective group (39.4% versus 28.4%; P = 0.04), which was associated with greater nutrition outpatient follow-up. In conclusion, nutritional consultation rates in inpatients with cirrhosis can be significantly improved after educational intervention and is associated with lower 90-day readmission rates.

ESPEN guideline on clinical nutrition in liver disease

This update of evidence-based guidelines (GL) aims to translate current evidence and expert opinion into recommendations for multidisciplinary teams responsible for the optimal nutritional and metabolic management of adult patients with liver disease. The GL was commissioned and financially supported by ESPEN. Members of the guideline group were selected by ESPEN. We searched for meta-analyses, systematic reviews and single clinical trials based on clinical questions according to the PICO format. The evidence was evaluated and used to develop clinical recommendations implementing the SIGN method. A total of 85 recommendations were made for the nutritional and metabolic management of patients with acute liver failure, severe alcoholic steatohepatitis, non-alcoholic fatty liver disease, liver cirrhosis, liver surgery and transplantation as well as nutrition associated liver injury distinct from fatty liver disease. The recommendations are preceded by statements covering current knowledge of the underlying pathophysiology and pathobiochemistry as well as pertinent methods for the assessment of nutritional status and body composition.

[Nutrition in intensive care medicine: Part 2: special nutritional problems]

Therapy of intensive care patients is often complicated by co-morbidities or complex systemic disorders such as sepsis. The necessity to generate an individualized nutritional regime has gained in importance in recent years as this essential part of supportive care has a direct impact on the prognosis of the patient. In the present article a special focus is put on particular questions of nutritional aspects of intensive care patients. The current guidelines and study data on disorders relevant in intensive care medicine, such as acute or chronic renal and liver failure, acute respiratory distress syndrome and sepsis are presented and discussed. Another focus is the establishment of an adequate nutritional regime for patients after operations or suffering from multiple trauma.

Nutrition therapy for liver diseases based on the status of nutritional intake

The dietary intake of patients with nonalcoholic fatty liver disease (NAFLD) is generally characterized by high levels of carbohydrate, fat, and/or cholesterol, and these dietary patterns influence hepatic lipid metabolism in the patients. Therefore, careful investigation of dietary habits could lead to better nutrition therapy in NAFLD patients. The main treatment for chronic hepatitis C (CHC) is interferon-based antiviral therapy, which often causes a decrease in appetite and energy intake; hence, nutritional support is also required during therapy to prevent undernourishment, treatment interruption, and a reduction in quality of life. Moreover, addition of some nutrients that act to suppress viral proliferation is recommended. As a substitutive treatment, low-iron diet therapy, which is relatively safe and effective for preventing hepatocellular carcinoma, is also recommended for CHC patients. Some patients with liver cirrhosis (LC) have decreased dietary energy and protein intake, while the number of LC patients with overeating and obesity is increasing, indicating that the nutritional state of LC patients has a broad spectrum. Therefore, nutrition therapy for LC patients should be planned on an assessment of their complications, nutritional state, and dietary intake. Late evening snacks, branched-chain amino acids, zinc, and probiotics are considered for effective nutritional utilization.

OBSERVATIONS ON THE CONDITIONS OF DIETARY HEPATIC INJURY (NECROSIS, CIRRHOSIS) IN RATS

Experimental dietary hepatic injury (diffuse or focal necrosis and cirrhosis in rats, with or without ascites and pleural and pericardial effusion) is determined by the dietary factors instrumental also in the production of fat infiltration of the liver and thus opposed to the lipotropic activity of casein. Accordingly, rats maintained on a diet low in casein with a moderately high or high content of fat and without choline regularly exhibited hepatic injury after between 100 and 150 days. Supplements of l-cystine had an aggravating effect on the production of cirrhosis of the liver, whereas a supplement of choline alone reduced the severity and the incidence of hepatic injury, although not decisively. The combined administration of l-cystine plus choline or of dl-methionine in adequate doses, however, proved to be highly effective in preventing injury to the liver. These conclusions have been corroborated by the use of different modifications of the basal diet. Rats with dietary hepatic injury exhibit, in sequence, changes that vary from diffuse necrosis resembling human acute or subacute yellow atrophy to advanced portal cirrhosis. Diffuse necrotizing nephrosis was a frequent accompaniment of the hepatic injury. Cystine again, proved to be a factor which aggravated this condition.

Effect of long-term late-evening snack on health-related quality of life in cirrhotic patients

AIM

In patients with liver cirrhosis, abnormal energy metabolism induces low health-related quality of life (HRQOL) scores. However, late-evening snack (LES) prevents morning starvation in cirrhotic patients. Our aim is to assess the effect of long-term LES on HRQOL in cirrhotic patients, using the 36-item Short Form (SF-36) health survey.

METHODS

Thirty-nine cirrhotic patients classified as Child-Pugh grade A were recruited. The patients were randomly divided into two groups: 24 were assigned to the non-LES group and 15 to the LES group. SF-36 scores, anthropometric data and serum biochemical parameters were examined in the non-LES and LES groups at 0, 6 and 12 months.

RESULTS

Neither anthropometric data nor laboratory data showed significant differences between the non-LES and the LES groups at 0, 6 and 12 months. The role-emotional (RE) HRQOL scores at 6 months and mental health (MH) scores at 6 and 12 months were significantly reduced from the baseline level in the non-LES group. In contrast, these scores remained unchanged in the LES group. General health perception (GH) scores at 12 months, RE at 6 months and MH at 6 and 12 months in the LES group were significantly higher than those of the non-LES group.

CONCLUSION

Long-term LES administration may be helpful in maintaining higher HRQOL in patients with cirrhosis.

Efficacy of long-term dietary restriction of total calories, fat, iron, and protein in patients with chronic hepatitis C virus

OBJECTIVES

A diet restrictive in total calories, fat, iron, and protein intake reduces serum alanine aminotransferase levels in patients with long-term hepatitis C virus infection. However, whether long-term dietary therapy causes adverse effects such as malnutrition and anemia due to a shortage of energy intake is not clear. We evaluated the balance of energy intake and changes in physical and hematologic indices of nutrition after a long-term dietary therapy.

METHODS

Twenty-two patients with long-term hepatitis C virus infection that did not respond to or who were able or unwilling to take interferon therapy were enrolled in this study. Our prescriptions included 7 mg/d or less of iron, 30 kcal. kg(-1). d(-1) of energy, 1.1 to 1.2 g. kg(-1). d(-1) of protein, and a fat energy fraction of 20%. Patients were followed for 24 mo.

RESULTS

Mean body fat percentage was 24.6% at entry and was significantly reduced after the diet prescription. Mean serum ferritin decreased significantly from 376 ng/mL at entry to 141 ng/mL after 24 mo. Mean serum alanine aminotransferase levels decreased significantly from 66 to 49 IU/L. Mean levels of hemoglobin, serum albumin, and cholinesterase did not change significantly during the follow-up period.

CONCLUSIONS

These results suggest that restriction of energy, fat, iron, and protein intakes is safely tolerated, so its long-term use should be recommended to patients with long-term infection with hepatitis C virus.

Vegetarian diets in hepatic encephalopathy: facts or fantasies?

Diet treatment characterized by a reduction in or a selection of food proteins is currently suggested in hepatic encephalopathy. This article is a review of the present knowledge about the characteristics and the rationale of vegetarian diets in cirrhotic patients with overt or latent encephalopathy. In addition, evidence relating diet and encephalopathy and the nutritional features and needs of cirrhotic patients is reported. Finally, the rationale of a diet based on vegetable and milk-derived proteins that may overcome the limits and the possible adverse effects of a strict vegetarian diet is presented.

A study of oral nutritional support with oxandrolone in malnourished patients with alcoholic hepatitis: results of a Department of Veterans Affairs cooperative study

A Veterans Affairs cooperative study involving 273 male patients was performed to evaluate efficacy of oxandrolone in combination with an enteral food supplement in severe alcoholic hepatitis. All patients had some degree of protein calorie malnutrition. On an intention-to-treat basis, only minimal changes in mortality were observed. However, in patients with moderate malnutrition mortality on active treatment at 1 mo was 9.4% compared with 20.9% in patients receiving placebo. This beneficial effect was maintained so that after 6 mo on active treatment 79.7% of patients were still alive, compared with 62.7% of placebo-treated patients (p = 0.037). Improvements in both the severity of the liver injury (p = 0.03) and malnutrition (p = 0.05) also occurred. No significant improvement was observed with severe malnutrition. To better determine the effect on therapeutic efficacy, we compared results with those from a nearly identical population (cooperative study 119) treated with oxandrolone but not given the food supplement. Patients were stratified according to their caloric intake (greater than 2,500 kcal/day was considered adequate to supply energy needs and promote anabolism). For patients with moderate malnutrition and adequate caloric intake, oxandrolone treatment reduced 6-mo mortality (4% active treatment vs. 28% placebo [p = 0.002]). For patients with moderate malnutrition and inadequate calorie intake, oxandrolone had no effect on mortality (30% active treatment vs. 33% placebo). In cases of severe malnutrition, oxandrolone had no effect on survival. However, adequate caloric intake was associated with 19% mortality, whereas patients with inadequate intake exhibited 51% mortality (p = 0.0001). These results indicate that nutritional status should be evaluated in patients with alcoholic hepatitis. When malnutrition is present, vigorous nutrition therapy should be provided, and in patients with moderate malnutrition oxandrolone should be added to the regimen.

Alcoholic liver disease

Liver injury may develop in some people who consume alcohol. The pathogenesis of liver damage in such subjects remains obscure. Major histopathologic features of alcohol-associated liver injury include steatosis, steatonecrosis, and cirrhosis. The clinical manifestations of alcoholic liver disease are nonspecific and range from asymptomatic hepatomegaly to stigmata of portal hypertension with advanced parenchymal failure. The severity of the clinical presentation and the degree of aminotransferase elevation correlate poorly with the liver histopathology, particularly in patients who continue to drink alcohol. Short-term mortality of such patients is best predicted by a composite of clinical and laboratory parameters that are influenced by alcohol consumption as well as by liver disease. Long-term prognosis is determined by residual damage to vital organs (that is, whether or not cirrhosis has developed) and whether or not the patient continues to drink. Current therapy of alcoholic liver disease includes abstinence and correction of nutritional deficiencies. Other therapies are experimental and are best utilized in the setting of controlled clinical trials.

Protein-calorie malnutrition associated with alcoholic hepatitis. Veterans Administration Cooperative Study Group on Alcoholic Hepatitis

Three hundred sixty-three alcoholic patients with alcoholic hepatitis were studied in six Veterans Administration medical centers. By history, alcohol consumption was 227.9 g per day, with a mean duration of 23.8 years. Cirrhosis accompanied the alcoholic hepatitis in 58.7 percent of the patients who underwent biopsy or autopsy. Complete nutritional assessment was performed in 284 patients, and observed nutritional changes were classified into those associated with marasmus or those characterizing kwashiorkor. A smaller comparison group of 21 alcoholic patients matched for age and alcohol consumption but without clinically evident liver disease was also studied in an identical manner. None of the patients with liver disease was completely free from malnutrition, whereas 62 percent of the alcoholic patients without liver disease showed abnormalities. In patients with alcoholic hepatitis, some findings associated with marasmus were seen in 86 percent, and some features of kwashiorkor were observed in 100 percent. When present together, the complete picture of kwashiorkor and marasmus correlated closely with the clinical severity of the liver disease (p less than 0.005). The nearly constant association of either complete or partial kwashiorkor or marasmus suggests that the separation of these two entities is artificial in alcoholic patients with liver disease. Although, experimentally, malnutrition may not be essential for the development of alcoholic hepatitis, clinically, it appears to precede the development of the liver injury, which suggests an interaction. Recognition is important so that appropriate nutritional therapy can be provided.
