Monitoring of patients on home parenteral nutrition (HPN) in Europe: a questionnaire based study on monitoring practice in 42 centres.

INTRODUCTION & AIM: To gather information about how adult patients on home parenteral nutrition (HPN) are monitored after discharge from the hospital. METHOD: A questionnaire about HPN monitoring practice was circulated to HPN centres in eight European countries through the representative of the ESPEN HAN-working group. Centres were asked about guidelines, home visits and how monitoring and handling of complications were managed. RESULTS: Fourty-two centres in eight European countries completed the questionnaire: UK n=14, France n=9, Belgium n=4, Italy n=4, Poland n=4, Denmark n=4, Spain n=2, Germany n=1. The HPN experience of the centres was in the range 2-30 years. Centres ranged in size from 0 to 125 HPN patients representing a total number of 934 of whom 54% had received HPN for more than 2 years. The primary disease was non-malignant in 90% whilst 10% had been diagnosed with active cancer. Of the centres 92% had a HPN team and 66% had written guidelines for monitoring HPN. Home visits after discharge for monitoring purposes were carried out by 31 of the centres involving the HPN team, general practitioner, community nurse or home care agency. Stable patients on HPN for more than 12 months were monitored at the discharging hospital (73%), at a local hospital (12%), by the General Practitioner (11%) or by a home care agency (4%). Of the centres, 90% reported that the main responsibility for monitoring was assigned to a specific person. The intervals between monitoring visits for the stable HPN patient was in the range 1-6 months, 52% of the centres reported intervals of 2-3 months. In case of complications 76% of centres reported that patients got in touch with the HPN team, 2% the local hospital, 5% the home care agency, and 17% other. Re-admission to hospital was usually to the HPN centre and only occasionally to a local hospital. CONCLUSION: In Europe a specialised team at the discharging hospital monitors HPN patients and 66% of the centres had some kind of written guidelines.

Nutritional deficiencies in patients with Crohn's disease in remission.

BACKGROUND: Patients with Crohn's disease (CD) are at risk of developing nutritional deficiencies, especially because of restrictive diets. The aim of our study was to assess food intake and the status for vitamins and trace elements in nonselected CD patients in clinical remission. METHODS: A total of 54 consecutive CD patients (28 females, 26 males, 39 +/- 2 years of age [mean +/- SD]) in clinical remission for >3 months underwent body composition, resting energy expenditure, nutrient intake, and plasma concentration assessment, and were compared with 25 healthy controls (16 females, 9 males, 38 +/- 3 years old). RESULTS: According to the nutritional risk index, 37 patients (70%) were not malnourished, 12 were at moderate risk, and 4 were at severe risk for malnutrition. Fat mass was lower in patients in remission compared with controls (P = 0.04). The mean daily energy intake was comparable between patients (2218 +/- 92 kcal/day) and controls (2066 +/- 101 kcal/day), covering their needs. No significant difference was observed for macronutrient intake in comparison with controls; compared to controls, female CD patients had lower intakes of beta-carotene (P < 0.005), vitamins B1 (P < 0.05), B6 (P < 0.01), and C (P < 0.005), and magnesium (P < 0.01). They had significantly higher intakes of zinc (P < 0.01). Male CD patients had lower intakes of beta-carotene and vitamin C (P < 0.05). More than 50% of patients had low plasma concentrations of vitamin C (84%), copper (84%), niacin (77%), and zinc (65%). CONCLUSIONS: In CD patients in remission, macronutrient needs are usually covered by food intake. However, micronutrient deficiencies are frequent and call for specific screening and treatment.

Candidates for intestinal transplantation: a multicenter survey in Europe.

OBJECTIVES: Epidemiology of candidacy for intestinal transplantation (ITx) and timing for referral for ITx are unknown. Patient candidacy and physician attitudes toward ITx were investigated among centers that participated in previous European surveys on home parenteral nutrition (HPN). METHODS: Patients on HPN for benign intestinal failure (IF) were evaluated by a structured questionnaire. Candidacy was assessed by USA Medicare and American Transplantation Society criteria, categorized as: (1) life-threatening HPN complications; (2) high risk of death because of the gastrointestinal disease; (3) IF with high morbidity or patient HPN refusal. Physicians judged candidacy as immediate or potential. RESULTS: Forty-one centers from nine countries enrolled 688 adults (> 18 yr) and 166 pediatric patients; 70% of patients were from five countries which collected 60-100% of their HPN patients. Candidacy was 15.7% in adults and 34.3% in pediatrics (HPN failure, 62.1% and 28.1%; gastrointestinal disease, 25.9% and 59.6%; high morbidity IF or HPN refusal, 12.0% and 12.3%, respectively). Immediate candidacy was required for 14.8% of adult and 15.8% of pediatric candidates (< 50% of candidates because of HPN-related liver failure). Among centers, the candidacy rate ranged 0-100% and was negatively associated with the number of patients enrolled in the survey (R = -0.463, p = 0.002). Among the major contributing countries, candidacy ranged 0.3-0.8/million inhabitants for adults and 0.9-2/million inhabitants < or = 18 yr for pediatric candidates. CONCLUSIONS: The rate of candidacy and the indications for ITx candidacy differed greatly among age groups and HPN centers; within countries candidacy was more homogeneous; physicians had a generally reserved attitude toward ITx.

Effects of total enteral nutrition supplemented with a multi-fibre mix on faecal short-chain fatty acids and microbiota.

BACKGROUND AND AIMS: Impaired bowel function is frequent in tube-fed patients, and diarrhoea is associated with decreased faecal short-chain fatty acids (SCFAs) concentrations. The aim of this study was to compare the effects of a multi-fibre-enriched formula (15 g/l) and a fibre-free isoenergetic and isonitrogenous formula on faecal SCFAs and microbiota in long-term enteral nutrition (EN) patients. METHODS: Fifteen patients [11M/4F, aged 53 (40-73)] on total EN for 43 (1-310) months for dysphagia received a fibre-free formula for 7 days, followed in a random order by either the multi-fibre-enriched formula for 14 days and then the fibre-free formula for 14 days or vice versa. Stool samples were taken at the end of each period for measurement of SCFAs levels and different groups of bacteria. Results were compared with non-parametric tests. RESULTS: After the multi fibre EN, there was a significant median increase in total faecal SCFAs (+84%), butyrate (+20%) and acetate (+147%) compared with baseline. A significant increase in the total number of bacteria as determined with the molecular method was found after the multi-fibre EN period compared with the fibre-free EN period. There were no concomitant changes in the dominant groups of intestinal bacteria. CONCLUSION: In long-term EN patients, a polymeric enteral formula supplemented with a mixture of six fibres increases faecal SCFAs and total number of bacteria, which may contribute to an improved bowel function.

[Cancer of an ectopic pancreas in the duodenal wall].

Ectopic pancreas is defined as pancreatic tissue outside the normal location of the pancreas. It can be affected by the same complications as the orthotopic pancreas, such as adenocarcinoma. This extremely rare complication (only 14 published cases) may have a better prognosis that adenocarcinoma of an orthotopic pancreas. Endoscopic ultrasonography may be useful in the diagnosis of this disease. We report a case of malignancy of the duodenal wall originating in aberrant pancreatic tissue, and review the literature.

Muscle performance in patients with Crohn's disease in clinical remission.

BACKGROUND: Because patients with Crohn's disease (CD) often show increased energy expenditure, nutritional deficiencies, and general fatigue, all which may persist after a flare, we hypothesized that CD could alter muscle mass and function. This study aimed to assess muscle strength and endurance in CD patients in clinical remission and the influencing factors. METHODS: Forty-one outpatients (17 men and 24 women; age, 37 +/- 10 yr), in remission (CD Activity Index < 150) for > 3 months, and 25 age-matched healthy controls (10 men and 15 women; age, 37 +/- 13 yr) were evaluated. Evaluation included a sit-up test, hand-grip strength test, hand-grip endurance test, lower limb strength test, and lower limb endurance test (LE), as well as a measure of physical activity. RESULTS: No significant difference was found between CD and control groups regarding weight, height, body mass index, fat mass, and fat-free mass. Strength performance was lower in CD subjects compared with controls, particularly for lower limb indexes: lower limb strength test (-24.6%, P < 0.001), LE (-25.8%, P < 0.001), and sit-up test (-25.1%, P < 0.001). Previous disease severity, disease duration, the cumulative dose of glucocorticosteroids, current inflammation, and global habitual physical activity did not affect muscle performance. A recent use of steroids improved LE. CONCLUSIONS: CD patients in clinical remission have decreased muscle function that may affect their quality of life. This pattern is reflected by reduced strength and endurance indexes, particularly for lower limbs. The reasons for these changes need further study. Strength training should be assessed in these patients.

Malnutrition is an independent factor associated with nosocomial infections.

The aim of the present prospective study was to determine if malnutrition, measured using a simple validated score, is an independent risk factor for nosocomial infections (NI) in non-selected hospital in-patients. Between 29 and 31 May 2001, a survey on the prevalence of NI was conducted on all 1637 in-patients (61 (SD 25) years old) in a French university hospital as part of a national survey. Actual and usual body weights were recorded in all in-patients, and serum albumin levels were measured on all blood samples taken during the week before the study. Nutritional status was evaluated by using the nutritional risk index (NRI). Albumin values were obtained in 1084 patients, and complete weight information was obtained in 911. Therefore, NRI was calculated in 630 patients (61 (SD 20) years old): 427 (67.8 %) were malnourished. NI prevalence was 8.7 %: 4.4 % in non-malnourished patients, 7.6 % in moderately malnourished patients and 14.6 % in severely malnourished patients. In univariate analysis, the odds ratios for NI were 1.46 (95 % CI 1.2, 2.1) in moderately malnourished patients and 4.98 (95 % CI 4.6, 6.4) in severely malnourished patients. In multivariate analysis, age, immunodeficiency and NRI class influenced NI risk. Vascular and urinary catheters, and surgical intervention, were the extrinsic factors associated with NI, with odds ratios ranging from 2.0 (95 % CI 1.8, 2.6) for vascular catheters to 10.8 (95 % CI 8.8, 12.6) for association of the three factors. In conclusion, in non-selected hospitalized patients, malnutrition assessed with a simple and objective marker is an independent risk factor for NI. An early screening for malnutrition may therefore be helpful to reduce the high prevalence of NI.

[Diarrhea during enteral feeding].

PREVALENCE: Diarrhea occurs in 2 to 70% of tube-fed patients, depending on their disease (with an increased risk in critically ill patients) and on the definition of diarrhea used. CONSEQUENCES: Diarrhea increases morbidity, particularly since the nutritional goals are harder to reach. CAUSES: Relevant causes today are related to the nutrition (irregular and too high output, jejunal site, low sodium and fiber contents), to the patient (malnutrition, stress, underlying diseases), and predominantly to concomitant treatments (antibiotics, with an increased risk of Clostridium difficile infection, laxative-containing drugs). TREATMENT: Treatment of the cause is only valid when it has been identified. Symptomatic treatment principally combines compensation for water and electrolyte loss and drugs that slow down the transit. Prevention associates the regulation of the administration rate and the fight against Clostridium difficile. Restoration of the colonic microflora appears the key to success and some prebiotics and probiotics have demonstrated preventive effects. Further research in this direction is warranted.

[Treatment of malnutrition: dietetic support and enteral nutrition].

Except in case of bowel obstruction or intestinal failure, nutritional support should be performed by oral or enteral route. In hospitalised patients, the decision of nutritional support depends on both nutritional state and spontaneous oral intake. Dietetic support can use energy enriched food and oral supplement. Enteral nutrition can be proposed in case of failure of dietetic support or at once in case of severe malnutrition or dysphagia. An early start and a good technique are conditions in order to improve outcome of patients.

Gut changes attributed to ageing: effects on intestinal microflora.

PURPOSE OF REVIEW: There is increased evidence of several impaired gastrointestinal functions with ageing. In the elderly, however, most gastrointestinal functions remain relatively intact because of the large reserve capacity of the intestine and the great secretion capacity of the pancreas. This review will focus on changes in gut microflora observed in the elderly and on the potential benefit of probiotics in this population. RECENT FINDINGS: Recent studies suggest that age affects the intestinal microflora with a decrease in anaerobes and bifidobacteria population and an increase in enterobacteria. These changes and the reduced intestinal immunity of the aged may favour gastrointestinal infections that are frequent in the elderly. Clostridium difficile-associated diarrhoea, one of the most common nosocomial infections in the elderly, has a profound effect on morbidity, mortality and health costs. Probiotics may have interesting positive effects on intestinal function, and the efficacy of treatment with Lactobacilli and Saccharomyces boulardii in Clostridium difficile-associated diarrhoea has been well established in a recent meta-analysis. Studies performed in healthy elderly patients suggest that diet supplementation with probiotics may reduce the impaired immunity associated with ageing. SUMMARY: Important changes in intestinal microflora of the elderly have recently been demonstrated and may have important clinical consequences. Further studies should be conducted to determine if the consumption of probiotics is associated with a lower infection rate and a higher effectiveness of vaccines.

Effect of age on substrate oxidation during total parenteral nutrition.

OBJECTIVE: Parenteral nutrition is increasingly used in the elderly. Aging is accompanied by metabolic changes that can modify substrate use. We compared substrate oxidation during cyclic total parenteral nutrition (TPN) in elderly and middle-aged patients. METHODS: Twelve elderly patients (eight women, four men; 72 +/- 5 y) and 12 middle-aged patients (nine women, three men; 39 +/- 13 y) who were on cyclic TPN for intestinal failure were investigated while in stable condition after at least 15 d of TPN. No patient was diabetic. Indirect calorimetry was performed during fasting and every 30 min during the 3 h of TPN infusion and 3 h after infusion, allowing the measurement of nutrient oxidation. Blood samples were obtained every hour for the measurement of glucose, insulin, triacylglycerols, and free fatty acids. RESULTS: In the fasting state, resting energy expenditure was significantly higher in the elderly patients than in the middle-aged patients (39.3 +/- 8.1 versus 31.9 +/- 4.3 kcal/kg of fat-free mass per day, P = 0.008). During TPN, lipid oxidation was significantly higher in the elderly patients than in the middle-aged patients (1.09 +/- 0.17 versus 0.84 +/- 0.27 mg x kg(-1) x min(-1), P = 0.011); glucose oxidation was significantly lower in the elderly patients than in the middle-aged patients (2.19 +/- 0.93 versus 3.22 +/- 1.54 mg x kg(-1) x min(-1), P = 0.038). Areas under the curves of glycemia and free fatty acids were significantly higher in the elderly patients. CONCLUSION: In the elderly, TPN was associated with significantly higher lipid oxidation and lower glucose oxidation than in younger patients. TPN formulas and flow rates should therefore be adapted in the elderly.

Diagnostic accuracy of a rapid urine-screening test (Multistix8SG) in cirrhotic patients with spontaneous bacterial peritonitis.

OBJECTIVE: To assess the diagnostic accuracy of a rapid urine-screening test (Multistix8SG) for spontaneous bacterial peritonitis (SBP) in cirrhotic patients. METHODS: Seventy-two consecutive patients (44 males, 28 females; mean age 61.6 years) with cirrhosis and ascites were included in the study. A diagnostic paracentesis was performed on hospital admission in all patients and 2 days after antibiotic treatment in the case of SBP (polymorphonuclear [PMN] count over 250/mm in ascitic fluid). Each fresh sample of ascitic fluid was also tested using the Multistix8SG urine test, and the results were scored as negative, trace or positive. RESULTS: Nine of the 72 patients had SBP and the Multistix8SG urine test was positive. After 48 h of antibiotic therapy, the PMN count of three of these nine patients was still above 250/mm and the Multistix8SG test remained positive. In three other patients with SBP, the PMN count dropped below 250/mm and the Multistix8SG test result had become negative. Two of the nine SBP patients died before 48 h, and paracentesis was not performed in the ninth case. In the other 63 patients, the PMN count in ascitic fluid was below 250/mm; the Multistix8SG test revealed 17 trace results and 46 negative results. At the threshold of 250 PMN/mm in ascitic fluid, this test had a sensitivity and a specificity of 100%. CONCLUSION: A positive Multistix8SG urine test result in ascitic fluid appears to be an indication for antibiotic treatment.

Effect of steroids on energy expenditure and substrate oxidation in women with Crohn's disease.

OBJECTIVE: Patients with Crohn's disease (CD) have increased energy expenditure and fat oxidation. Steroids, commonly used to treat flare-up of CD, induce weight gain. This study was designed to evaluate the effects of prednisone and budesonide on energy expenditure and substrate oxidation in patients with CD. METHODS: Twenty-nine women with CD and 10 healthy controls were studied. Ten patients received prednisone (0.75-1.0 mg/kg/day), nine received budesonide (9 mg/ day), and 10 did not receive steroids. Resting energy expenditure and substrate oxidation were measured by indirect calorimetry in a fasting state and after a standard diet. RESULTS: In the fasting state, resting energy expenditure was higher in patients without steroids than in the controls. Lipid oxidation was lower (p < 0.01) in patients with prednisone (0.46 +/- 0.39 mg/kg/min) than in patients with budesonide (0.97 +/- 0.28 mg/kg/min) and without steroids (1.06 +/- 0.32 mg/kg/min), but was similar with control subjects (0.47 +/- 0.20 mg/kg/min). Postprandially, lipid oxidation was lower (p < 0.01) in patients with prednisone (0.32 +/- 0.23 mg/kg/min) than in patients with budesonide (0.75 +/- 0.20 mg/kg/min), without steroids (0.82 +/- 0.23 mg/kg/min), and controls (0.58 +/- 0.15 mg/kg/min). Protein oxidation was significantly higher in patients with prednisone than in the other subjects. CONCLUSIONS: In women with CD, prednisone decreases lipid oxidation and increases protein oxidation. These effects are not observed with budesonide and may contribute to the weight gain and side effects commonly observed with prednisone. A low-fat/high-protein diet could be proposed during a course of prednisone.
