Nutritional state and energy balance in cirrhotic patients with or without hypermetabolism. Multicentre prospective study by the 'Nutritional Problems in Gastroenterology' Section of the Italian Society of Gastroenterology (SIGE).

BACKGROUND AND AIMS: A total of 334 stable, compensated cirrhotic patients admitted to 10 Italian Gastroenterology Units were included in a prospective study to evaluate nutritional state and energy balance in liver cirrhosis. MATERIALS AND METHODS: Nutritional state and calorie intake were examined in the total population, while adequacy of calorie intake versus measured total energy expenditure was evaluated in a comparable subpopulation and in 40 matched controls, by computing the energy balance. RESULTS: Our data demonstrated that: (i) malnutrition was present in 25% of the total patients and significantly correlated with the Child's group (A=16%; B=25%; C=44%); (ii) the type of malnutrition is influenced by mBEE: normometabolic patients exhibit a significant (p<0.005) reduction of mid-arm fat area while both hypermetabolic and hypometabolic patients show a significant (p<0.005) decline in kg of free fat mass; (iii) normometabolic and hypometabolic patients have a negative energy balance, due to a high level of physical activity (127+/-14 kJ) in the first group and a reduced energy intake/kg body weight (102+/-12 kJ) in the second; (iv) hypermetabolic patients have a positive energy balance due to decreased daily physical activity/kg body weight (108+/-28 kJ); (v) malnourished and normometabolic patients eat a significantly (p<0.05) reduced percentage of protein whereas malnourished and hypermetabolic patients eat a significantly increased percentage of fat (p<0.05). CONCLUSION: Although multivariate regression analysis confirms that the Child-Pugh's score is a better independent predictor of malnutrition, the measure of REE, TEE, calorie intake and energy balance need to be routinely performed in cirrhotic patients, in order to recognise hypermetabolic and hypometabolic patients (approximately 30%) in whom the nutritional and metabolic parameters are indispensable as a basis for designing and prescribing personalised nutritional strategies that can treat muscle malnutrition and thus improve the morbidity and mortality rates.

Gallstone disease and related risk factors in patients with Crohn disease: analysis of 330 consecutive cases.

BACKGROUND: The reported prevalence of gallstone disease (GD), defined as current gallstones or previous cholecystectomy for gallstones, in patients with Crohn disease ranges from 13% to 34%. The aim of this study was to characterize the still undefined risk factors of this complication. METHODS: A total of 330 consecutive patients with Crohn disease (189 males and 141 females aged 17-82 years, mean +/- SD age, 41 +/- 14 years) underwent liver ultrasonography. RESULTS: A diagnosis of GD was made in 78 patients (24%), 54 with current gallstones and 24 who had undergone previous cholecystectomy. Its frequency was comparable in males and females (23% vs 25%), but was significantly associated with age (P =.001), being 13%, 36%, and 51% in patients aged 44 years and younger, 45 to 59 years, and 60 years and older, respectively (P =.001). Its prevalence significantly differed according to the site of the disease at diagnosis (P =.02) and was unrelated to disease duration. Gallstone disease was more frequent in patients who had undergone surgery (34% vs 14%; P =.001) and was significantly associated with the number (P =.001) and site of bowel resections (P =.001), increasing from 28% in the patients who had undergone 1 resection to 53% in those having had 2 or more resections (P =.005) and being significantly higher in patients with a resection involving the ileocecal region. Multivariate analysis showed that age; site of disease at diagnosis; and the presence, number, and site of bowel resections were significantly related to GD. CONCLUSIONS: In patients with Crohn disease, the frequency of GD is significantly higher than that reported in the general population with comparable characteristics (z = 5.04, P<.001). Age; site of disease at diagnosis; and the history, number, and site of bowel resections are independently associated with GD.

Imaging techniques and combined medical and surgical treatment of perianal Crohn's disease.

Crohn's disease is a chronic inflammatory disease which may involve any segment of the gastrointestinal tract, most frequently the terminal ileum, the large intestine, and the perianal region. The symptoms of perianal Crohn's disease include skin disorders, hemorrhoids, anal ulcers, anorectal stenosis, perianal abscesses and fistulas, rectovaginal fistulas and carcinoma of the perianal region. The perianal manifestations of Crohn's disease cause great discomfort to the patient and are among the most difficult aspects to treat. Management of perianal disease requires a combination of different imaging modalities and a close cooperation between gastroenterologists and dedicated surgeons.

A puzzling jaundice.

In an adult beta-thalassaemic patient admitted on account of the sudden onset of nausea, vomiting and biliary pain, the concomitant jaundice was considered "obstructive" on the basis of ultrasonographic evidence of cholecysto-choledocal stones. However, when the patient was re-evaluated it was found that concomitant Gilbert's disease, hepatitis C virus related cirrhosis and dilated cardiomyopathy had a detrimental effect on clinical and laboratory findings.

Clinical nutrition practice in Italian Gastroenterology Units.

BACKGROUND: Nutritional status affects the course, ensuing complications and prognosis of virtually all diseases. AIMS: To define the role of nutrition in Gastroenterology Units by means of two investigations that analyse: a) availability of devices for assessing nutritional status; b) nutritional treatment in clinical practice: incidence and frequency of indications for its use, together with type of treatment adopted. PATIENTS AND METHODS: Two questionnaires were sent to Italian Academic and Hospital Gastroenterology Units, all with clinical wards. RESULTS: Results refer to 27 Units, 22 of which took part in both parts of the analysis, enrolling 547 patients during the two-week study The first analysis shows that scales and the altimeter are not available everywhere, while more specific tools, such as skinfold calipers are available in 54% of the Units, and caloric intake can be assessed in 22-41%. The second analysis reveals that nutritional treatment was necessary in 50% of patients in the series examined, and that this was taken into account and prescribed in almost all cases (91%). Of the patients treated, 69% received dietetic supplementation and 31% artificial nutrition [12% enteral, 88% parenteral), although supportive parenteral nutrition is often contraindicated in conditions where good bowel function provides the conditions for enteral nutrition. CONCLUSION: Data emerging from the investigation showed that i) artificial nutrition is commonly used in gastroenterology Units in Italy although 23% of them never consider either enteral or parenteral nutrition as medical treatment of gastrointestinal disease; ii) malnutrition is a very frequent complication (mean 27%; range 4-55%0) in Gastroenterology Unit patients albeit only 42% of malnourished patients received artificial nutrition; iii) indications for enteral and parenteral nutrition are not always respected, as there is an excessive use of parenteral nutrition and an unjustified resistance to the use of enteral nutrition; iv] nutritional treatment is often administered without adequate nutritional assessment and without a complete adherence to the standards recommended for preparation of parenteral bags, supported by suitable technology; v) only two Gastroenterology Units report admitting and following patients in a home parenteral nutrition programme; vi) this investigation probably reflects the response of those Gastroenterology Units most aware of the importance of nutritional problems. Better awareness of correct practices for nutritional support should be promoted, encouraging greater use of diagnostic and monitoring techniques and a more discerning choice of the most suitable type of artificial nutrition to be administered in gastroenterology

Increased cancer risk in a cohort of 230 patients with hereditary hemochromatosis in comparison to matched control patients with non-iron-related chronic liver disease.

It has been suggested that excess iron may facilitate the occurrence of cancer. Patients with hereditary hemochromatosis (HH) are at high risk of developing liver cancer, and studies of limited series reported a high frequency of nonhepatic cancers. To verify whether patients with HH are at higher risk of liver cancer and other malignancies as compared with patients with non-iron-related chronic liver disease (CLD), we analyzed the occurrence of neoplasms in 230 patients with HH and 230 with non-iron-related CLD. The patients were matched by sex, age, duration of follow-up (+/-5 years), and severity of liver disease. On enrollment, the following variables were considered: hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, alcohol abuse, smoking, and a family history of cancer (first-degree relatives). The diagnosis of primary cancers was confirmed by histology. During the follow-up, hepatocellular carcinoma (HCC) developed in 49 and 29 patients (all cirrhotic patients) with HH and non-iron-related CLD, respectively, with a relative risk of 1.8 (95% confidence interval [CI] 1.1-2.9); nonhepatic cancers occurred in 20 and 11 patients, respectively, with a relative risk of 1.8 (95% CI 0.8-4). Four patients with HH and 1 with non-iron-related CLD developed 2 different primary cancers during follow-up. The risk of cancer after adjustment for alcohol abuse, smoking, and family history of cancer was 1.9 (95% CI 1.1-3.1) in the patients with HH. In conclusion, patients with HH are at high risk of both liver cancer and other malignancies, which should be carefully sought during follow-up.
