Functional bowel symptoms in quiescent inflammatory bowel diseases: role of epithelial barrier disruption and low-grade inflammation.

OBJECTIVE: To determine the role of colonic barrier defects and low-grade inflammation in irritable bowel syndrome (IBS)-like symptoms in quiescent inflammatory bowel disease (IBD). DESIGN: Caecal biopsies were collected from 51 IBS, 49 quiescent IBD (31 Crohn's disease (CD) and 18 ulcerative colitis (UC)) patients and 27 controls. IBS was assessed using the Rome III criteria and the IBS severity score. Epithelial barrier integrity was evaluated by determining the paracellular permeability of biopsies mounted in Ussing chambers and the mRNA expression of tight junction proteins (ZO-1, α-catenin and occludin). Low-grade inflammation was evaluated by counting cells, including intraepithelial lymphocytes (IELs), eosinophils and mast cells, and by determining the mRNA and protein expression of tumour necrosis factor (TNF)-α in biopsies and culture supernatants. RESULTS: IBS-like symptoms were present in 35.4 and 38% of CD and UC patients, respectively. Paracellular permeability was significantly increased in both quiescent IBD with IBS-like symptoms and IBS compared with quiescent IBD without IBS-like symptoms (p<0.01, respectively) or controls (p<0.01, respectively). Significantly lower expression of ZO-1 and α-catenin was detected in IBS and quiescent IBD with IBS-like symptoms. IELs and TNF-α were significantly increased in quiescent IBD with IBS-like symptoms, but not in IBS. CONCLUSIONS: In quiescent IBD, IBS-like symptoms related to persistent subclinical inflammation associated with increased colonic paracellular permeability. A persistent increase in TNF-α in colonic mucosa may contribute to the epithelial barrier defects associated with abdominal pain in quiescent IBD, but not in IBS. Optimisation of anti-inflammatory therapy may be considered in quiescent IBD with IBS-like symptoms.

Infliximab is an effective option in patients with ulcerative colitis previously exposed to full subcutaneous anti-TNF agent: Results from a real-world multicenter study.

BACKGROUND: Data on infliximab efficacy in bio-exposed patients with ulcerative colitis (UC) are limited. AIMS: To evaluate infliximab effectiveness and its predictors in UC patients with prior exposure to subcutaneous (SC) anti-TNF agent. METHODS: In this multicenter retrospective study (8 centers), we included all consecutive UC patients with prior exposure to subcutaneous anti-TNF, starting infliximab for symptomatic UC, excluding acute severe colitis. Corticosteroid-free clinical remission (CFREM) was assessed at week 14 (W14) and W52 while endoscopic improvement (CFREM + endoscopic Mayo score≤1) was evaluated at W14. RESULTS: Overall, 104 patients were included (pancolitis=54.8%, primary failure to subcutaneous anti-TNF=57.4%, concomitant immunosuppressant=53.8%, median partial Mayo score at baseline=7[5-8]). The rate of CFREM was 33.6% (35/104) at W14 and 40.4% (42/104) at W52. At W14, endoscopic improvement was achieved in 29.8%(31/104). In multivariable analysis, concomitant immunosuppressant was associated with higher rate of CFREM at W14(OR=2.83[1.06-7.54], p = 0.037) and W52(OR=2.68[1.16-6.22];p = 0.021), while primary failure to a previous subcutaneous anti-TNF agent led to lower rate of CFREM at W14 (OR=0.37[0.14-0.98], p = 0.046). After a median follow-up of 20.9 months[11.7-33.7]), 50.0%(52/104) patients had discontinued infliximab. CONCLUSION: Infliximab is an effective option in UC patients previously exposed to prior subcutaneous anti-TNF agent and should be used with concomitant immunosuppressant.

Management and clinical outcome of rectal cancer in patients ≥ 80 years treated in southern France (PACA region) between 2006 and 2008.

BACKGROUND: Rectal cancer is increasingly prevalent in the elderly patients. Their clinical history and outcome after treatment are poorly described. This retrospective study was undertaken to provide more data and to compare therapeutic strategies to the standard of care for younger patients. PATIENTS AND METHODS: Data were retrospectively provided by gastroenterologists, oncologists, and gerontologists of Provence-Alpes-Côte-d'Azur (PACA). Patients concerned were aged 80 years or older, with a rectal cancer diagnosed between 2006 and 2008, irrespective of stage and (the) treatment of the disease. Overall survival (OS) and relapse-free-survival (RFS) were correlated with patient characteristics and treatment. The adopted therapeutic strategy was then compared to the standard-of-care for younger patients. RESULTS: Median follow-up was 36 months. The 3-year OS was 47.4% for the 160 patients analyzed, and 59.2% for the 117 patients treated with curative intent. The 3-year RFS was 76.6% in the "curative" population. In the multivariate analysis, node status and surgery independently influenced OS, while RFS was influenced by age, N status, and gender. For T0-T2 tumors, patients were treated similar to younger patients with an OS of 83.6% and a RFS of 95.2%, respectively. For T3-T4 tumors, 3-year RFS was 65%, even with a less aggressive strategy. CONCLUSION: Surgical resection after evaluation using Comprehensive Geriatric Assessment (CGA) should be the standard treatment for localized rectal cancer (T0-T2) in elderly patients, as it is in younger patients. For locally advanced lesions (T3-T4), results obtained after a conservative approach suggest that a non-surgical strategy can be used in elderly patients.

Combination of allergic factors can worsen diarrheic irritable bowel syndrome: role of barrier defects and mast cells.

OBJECTIVES: Recent evidence suggests a role for increased colonic permeability and mucosal mast cell (MC) mediators on symptoms related to the irritable bowel syndrome (IBS). Whether allergic factors (AFs) are involved in the pathophysiology of IBS is unclear. We addressed the question of the possible influence of an allergic background on IBS symptoms. METHODS: We assessed paracellular permeability, mucosal MCs counts, and spontaneous release of tryptase of colonic biopsy specimens in 34 IBS patients and 15 healthy subjects. The severity of IBS was assessed through self-reported questionnaires. All individuals were tested for the presence of AF, including self-perception of adverse reaction to food, personal and familial history of atopic disease, elevated total or specific immunoglobulin E against food/inhalant antigens, blood eosinophilia, and skin tests. RESULTS: IBS patients had significant enhanced colonic permeability, higher number of MCs, and spontaneous release of tryptase than healthy subjects. The severity of IBS was significantly correlated with colonic permeability (r=0.48, P=0.004), MCs counts (r=0.36, P=0.03), and tryptase (r=0.48, P=0.01). In 13 IBS patients (38.2%) having at least three AFs, symptoms scores, colonic permeability, MCs counts, and tryptase release by colonic biopsies were significantly higher than in those with less than three AFs. IBS patients with at least three AFs were more prone to diarrhea or alternating symptoms. None AF was found to be predictive of IBS severity. CONCLUSIONS: In IBS patients, the presence of an allergic background correlates with a more severe disease and diarrhea predominance, possibly by enhancing mucosal MC activation and paracellular permeability.

Impact of an Education Programme on IBD Patients' Skills: Results of a Randomised Controlled Multicentre Study [ECIPE].

BACKGROUND: Better patient knowledge on inflammatory bowel disease [IBD] could improve outcome and quality of life. The aim of this study was to assess if an education programme improves IBD patients' skills as regards their disease. METHODS: The GETAID group conducted a prospective multicentre randomised controlled study. IBD patients were included at diagnosis, or after a significant event in the disease course. Patients were randomised between 'educated' or control groups for 6 months. Education was performed by trained health care professionals. A psycho-pedagogic score [ECIPE] was evaluated by a 'blinded' physician at baseline and after 6 and 12 months [M6 and M12]. The primary endpoint was the increase of ECIPE score at M6 of more than 20%. RESULTS: A total of 263 patients were included in 19 centres (male:40%; median age:30.8; Crohn's disease [CD]:73%). Of these, 133 patients were randomised into the educated group and 130 into the control group. The median relative increase in ECIPE score at M6 was higher in the educated group as compared with the control group (16.7% [0-42.1%] vs 7% [0-18.8%], respectively, p = 0.0008). The primary endpoint was met in 46% vs 24% of the patients in the educated and control groups, respectively [p = 0.0003]. A total of 92 patients met the primary endpoint. In multivariate analysis, predictors of an increase of at least 20% of the ECIPE score were randomisation in the educated group (odds ratio [OR] = 2.59) and no previous surgery [OR = 1.92]. CONCLUSIONS: These findings support the set-up of education programmes in centres involved in the management of IBD patients.

Nutritional consequences and nutrition therapy in Crohn's disease.

75% of hospital patients with Crohn's disease (CD) suffer from malnutrition and one third of CD patients have a body mass index below 20. Inflammatory bowel diseases (IBD) patients have many vitamin and nutrient deficiencies which can lead to important consequences such as hyperhomocysteinemia which is associated with a higher risk of thromboembolic disease. Nutritional deficiencies in IBD patients are the result of insufficient intake, malabsorption and protein-losing enteropathy as well as the metabolic distubances directly induced by the chronic disease and its treatments, in particular corticosteroids. Screening for nutritional deficiencies in chronic disease patients is warranted. Managing the deficiencies involves simple nutritional guidelines, vitamin supplements, and nutritional support in the worst cases, in particular in children in order to limit the impact of IBD on growth. In active CD, enteral nutrition is the first line therapy in children and should be used as sole therapy in adults mainly when treatment with corticosteroids is not feasible.

Mast cells and cellularity of the colonic mucosa correlated with fatigue and depression in irritable bowel syndrome.

BACKGROUND: A subset of patients with irritable bowel syndrome (IBS) have an increased number of mast cells (MCs) in the colonic mucosa. Psychological factors are believed to contribute to the course of IBS. AIMS: To examine associations between fatigue, depression and MCs of the colonic mucosa in IBS. METHODS: Colonic biopsies were taken from 50 Rome II IBS patients, 21 healthy controls and 11 depressed/fatigued patients without IBS. The cellularity of the lamina propria was determined as the number of inflammatory cells per high power field (hpf) through a 400x microscope. The Fatigue Impact Scale (FIS) and the short form Beck Depression Inventory (BDI) evaluated the severity of fatigue and depression. RESULTS: IBS patients had a significant increase in the cellularity of the lamina propria compared with controls or with depressed patients (mean (SD) 94.5 (48-110) vs 68 (58-82) and 78 (87-90) cells per hpf, p = 0.005 and p = 0.05, respectively), in particular of MCs (9.3 (5.6-11.7) vs 4.0 (2.7-6.8) and 4.3 (2.8-7.8) cells per hpf, p = 0.001 and p = 0.005, respectively). Both the FIS and BDI scores were significantly higher in IBS or in depressed patients than in controls (p<0.001). In IBS, the FIS score correlated significantly with the cellularity of the lamina propria (r = 0.51, p<0.0001) and MCs (r = 0.64, p<0.0001). In IBS, the BDI score correlated significantly with MCs (r = 0.29, p = 0.03). CONCLUSIONS: Elevated MCs counts are a key feature of the low-grade inflammatory infiltrate in the caecal mucosa of IBS. Fatigue and depression are associated with mucosal cell counts, in particular MCs, suggesting that psychological factors are associated with the low-grade inflammatory infiltrate in IBS.

Low risk of irritable bowel syndrome after Clostridium difficile infection.

OBJECTIVE: The incidence of postinfectious irritable bowel syndrome (IBS) ranges between 4% and 32% of individuals after bacterial or parasitic infection. This study analyzed IBS symptoms in hospitalized patients three months after a symptomatic Clostridium difficile infection. PATIENTS AND METHODS: All patients with a proven, symptomatic C difficile infection identified in the department of bacteriology over a four-month period were considered for enrolment. Patients were excluded in cases of pre-existing IBS or other organic gastrointestinal diseases. Patients completed both modified Talley and Rome II questionnaires within five days of clinical improvement with metronidazole and at three months postinfection, when stools were cultured and C difficile toxins were examined to exclude ongoing infection. RESULTS: Twenty-three patients were evaluated three months after infection with C difficile. Just after infection, 15 patients were symptom free, whereas eight patients exhibited symptoms suggestive of IBS. Three months after infection, 22 patients remained symptom free, whereas one patient presented with symptoms indicative of IBS. That female patient had a prolonged infection without vomiting. CONCLUSIONS: We have shown that while transient functional bowel disorder occurred in 34.7% of patients (eight of 23 patients) recently infected with C difficile, only 4.3% of patients (one of 23 patients) had symptoms indicative of IBS after three months (ie, postinfectious IBS). Because an age-related reduction in immune responsiveness has been documented, it can be speculated that the low incidence of postinfectious IBS may be explained by the older age of the study population. Therefore, it cannot be excluded that the findings may be different in younger patients.

[Transcatheter embolization for endoscopically unmanageable acute nonvariceal upper gastrointestinal hemorrhage]. / Traitement par embolisation endovasculaire d'hémorragies gastro-intestinales hautes non variqueuses et aiguës après échec du traitement endoscopique.

OBJECTIVES: Evaluate the efficacy of endovascular embolization for patients with endoscopically unmanageable acute nonvariceal upper gastrointestinal hemorrhage as well as the factors that may influence mortality. MATERIALS AND METHODS. Retrospective study over a 4-year period including a historical cohort of 37 consecutive patients (22 men), with a mean age of 69.2 years (range, 22-93 years). In most cases (54%), the hemorrhage stemmed from a gastrointestinal ulcer. Technical, primary clinical, and secondary clinical success rates, as well as complication rates, were calculated. Several clinical and angiographic parameters were compared to the early mortality rate using Kruskal-Wallis or Fisher tests. RESULTS: Technical, primary clinical, secondary clinical success rates, and complication rates were, respectively, 89.2%, 83.8%, 88.9%, and 10.8%. The early mortality rate was 32.4%. The APACHE II and IGS II scores were strongly correlated with mortality (p=0.001 and p=0.003, respectively). CONCLUSION: Endovascular embolization in patients with endoscopically unmanageable acute nonvariceal upper gastrointestinal hemorrhage is effective. However, the mortality rate remains high because of the changes in the clinical condition of these patients.

Efficacy and safety of golimumab in Crohn's disease: a French national retrospective study.

BACKGROUND: Anti-tumour necrosis factor (TNF) agents have improved the care of Crohn's disease (CD). After the first anti-TNF discontinuation, it is possible to switch to another anti-TNF. Three anti-TNF agents are available for ulcerative colitis (infliximab, adalimumab and golimumab), but only the first 2 have been approved for CD because golimumab has not been studied for this indication. AIM: To report the efficacy and safety of golimumab in CD. METHODS: Crohn's disease patients who received golimumab were identified in 12 French tertiary centres and were retrospectively analysed. The primary endpoint was the duration of golimumab treatment before escalation or discontinuation. The clinical response was defined as a decrease of more than 3 points in the Harvey-Bradshaw index or by global physician assessment. RESULTS: One hundred and fifteen patients were included. The golimumab treatment duration was 9.8 months (0.55-44), and 48.7% of the patients were still under treatment at the end of follow-up. Clinical response was observed in 55.8% of the patients after a mean duration of 3.8 months. The probability of remaining under treatment without escalation at 6, 12 and 24 months was 54.6%, 34.9% and 19.3% respectively. In multivariate analysis, discontinuation of the first anti-TNF agent due to intolerance (odds ratio, OR = 2.16; 95% CI, confidence interval [1.25-3.86]; P = .005) and co-immunosuppression for more than 6 months (OR = 3.98; 95% CI [2.3-7.1]; P < .0001) were predictive factors of efficacy. Six per cent of the patients discontinued treatment due to intolerance. CONCLUSION: After failure of infliximab or adalimumab for Crohn's disease, golimumab was safe and seemed beneficial in half of the patients.

Impact of Intragastric Balloon Before Laparoscopic Gastric Bypass on Patients with Super Obesity: a Randomized Multicenter Study.

BACKGROUND: Super obese patients are recommended to lose weight before bariatric surgery. The effect of intragastric balloon (IGB)-induced weight loss before laparoscopic gastric bypass (LGBP) has not been reported. The aim of this prospective randomized multicenter study was to compare the impact of preoperative 6-month IGB with standard medical care (SMC) in LGBP patients. METHODS: Patients with BMI >45 kg/m2 selected for LGBP were included and randomized to receive either SMC or IGB. After 6 months (M6), the IGB was removed and LGBP was performed in both groups. Postoperative follow-up period was 6 months (M12). The primary endpoint was the proportion of patients requiring ICU stay >24 h; secondary criteria were weight changes, operative time, hospitalization stay, and perioperative complications. RESULTS: Only 115 patients were included (BMI 54.3 ± 8.7 kg/m2), of which 55 underwent IGB insertion. The proportion of patients who stayed in ICU >24 h was similar in both groups (P = 0.87). At M6, weight loss was significantly greater in the IGB group than in the SMC group (P < 0.0001). Three severe complications occurred during IGB removal. Mean operative time for LGBP was similar in both groups (P = 0.49). Five patients had 1 or more surgical complications, all in the IGB group (P = 0.02). Both groups had similar hospitalization stay (P = 0.59) and weight loss at M12 (P = 0.31). CONCLUSION: IGB insertion before LGBP induced weight loss but did not improve the perioperative outcomes or affect postoperative weight loss.

ESPEN Guidelines on Enteral Nutrition: Gastroenterology.

Undernutrition as well as specific nutrient deficiencies have been described in patients with Crohn's disease (CD), ulcerative colitis (UC) and short bowel syndrome (SBS). The present guideline gives evidence-based recommendations for the indication, application and type of formula of enteral nutrition (EN) (oral nutritional supplements (ONS) or tube feeding (TF)) in these patients. It was developed in an interdisciplinary consensus-based process in accordance with officially accepted standards and is based on all relevant publications since 1985. ONS and/or TF in addition to normal food is indicated in undernourished patients with CD or CU to improve nutritional status. In active CD EN is the first line therapy in children and should be used as sole therapy in adults mainly when treatment with corticosteroids is not feasible. No significant differences have been shown in the effects of free amino acid, peptide-based and whole protein formulae for TF. In remission ONS is recommended only in steroid dependent patients in CD. In patients with SBS TF should be introduced in the adaptation phase and should be changed with progressing adaptation to ONS in addition to normal food.

Fistula Plug in Fistulising Ano-Perineal Crohn's Disease: a Randomised Controlled Trial.

BACKGROUND AND AIMS: Anal fistula plug [AFP] is a bioabsorbable bioprosthesis used in ano-perineal fistula treatment. We aimed to assess efficacy and safety of AFP in fistulising ano-perineal Crohn's disease [FAP-CD]. METHODS: In a multicentre, open-label, randomised controlled trial we compared seton removal alone [control group] with AFP insertion [AFP group] in 106 Crohn's disease patients with non- or mildly active disease having at least one ano-perineal fistula tract drained for more than 1 month. Patients with abscess [collection ≥ 3mm on magnetic resonance imaging or recto-vaginal fistulas were excluded. Randomisation was stratified in simple or complex fistulas according to AGA classification. Primary end point was fistula closure at Week 12. RESULTS: In all, 54 patients were randomised to AFP group [control group 52]. Median fistula duration was 23 [10-53] months. Median Crohn's Disease Activity Index at baseline was 81 [45-135]. Fistula closure at Week 12 was achieved in 31.5% patients in the AFP group and in 23.1 % in the control group (relative risk [RR] stratified on AGA classification: 1.31; 95% confidence interval: 0.59-4.02; p = 0.19). No interaction in treatment effect with complexity stratum was found; 33.3% of patients with complex fistula and 30.8% of patients with simple fistula closed the tracts after AFP, as compared with 15.4% and 25.6% in controls, respectively [RR of success = 2.17 in complex fistula vs RR = 1.20 in simple fistula; p = 0.45]. Concerning safety, at Week 12, 17 patients developed at least one adverse event in the AFP group vs 8 in the controls [p = 0.07]. CONCLUSION: AFP is not more effective than seton removal alone to achieve FAP-CD closure.

[Management and clinical outcome in patients over 80 years with rectal cancer treated between 2006 and 2008 in Southern France (PACA region)]. / Prise en charge et devenir des patients de plus de 80ans atteints d'un cancer du rectum, en région Provence-Alpes-Côte-d'Azur de 2006 à 2008.

PURPOSE: Rectal cancer is increasingly prevalent in elderly patients. Their clinical history and outcome after treatment are poorly described. This retrospective study was undertaken to provide more data and to compare therapeutic strategies to the standard of care for younger patients. PATIENTS AND METHODS: Patients concerned were aged 80 years or older, with a rectal cancer diagnosed between 2006 and 2008 and treated in Provence-Alpes-Côte-d'Azur (PACA), irrespective of stage and treatment of the disease. Overall survival and relapse-free-survival were correlated with patients' characteristics and treatment. The adopted therapeutic strategy was then compared to the standard-of-care for younger patients. RESULTS: With a median follow-up of 36 months, among the 160 patients included, the 3-year overall survival and relapse-free survival were 59.2% and 76.6%, respectively for the 117 patients who received a treatment with curative intent. In the multivariate analysis, node status and surgery independently influenced overall survival, while relapse-free survival was influenced by age, N status, and gender. For T0-T2 tumours, patients were treated similarly to younger patients with an overall survival of 83.6% and a relapse-free survival of 95.2%. For T3-T4 tumours, the 3-year relapse-free survival was 65%, even with a less aggressive strategy. CONCLUSION: Surgical resection after evaluation using the Comprehensive Geriatric Assessment (CGA) test should be the standard treatment for localized rectal cancer (T0-T2) in elderly patients, as it is in younger patients. For locally advanced lesions (T3-T4), results obtained after a conservative approach suggest that a non-surgical strategy can be used in elderly patients.

Efficacy of sustained combination therapy for at least 6 months with thiopurines and infliximab in patients with ulcerative colitis in clinical remission: a retrospective multicenter French experience.

BACKGROUND AND AIMS: Long-term benefits of combination therapy (combotherapy) with infliximab (IFX) and azathioprine (AZA) have been less studied in ulcerative colitis (UC) than in Crohn's disease. The aim of the present study was to determine UC disease activity in patients who received at least 6 months of combotherapy, and whether cotreatment for more than 6 months was useful in these patients. METHODS: A retrospective multicenter study was conducted in seven French academic centers from January 2010 to September 2012, including all UC patients having received at least 6 months of combotherapy in prolonged remission off steroids. During the follow-up period, which was divided into trimesters, scheduled IFX was continued as maintenance and AZA could be withdrawn. Assessment of UC activity by trimester was based on the following events: disease relapse defined by clinical relapse requiring a change of treatment, IFX failure, and colectomy. RESULTS: Eighty-two patients were included (mean age 38 years; male:female ratio 1:1) and followed up for a median of 22.3±14.0 months. Comparing 393 trimesters of combotherapy with 282 trimesters of IFX alone, fewer clinical relapses were observed with combotherapy (p = 0.049). Similar results were observed for IFX failure (p = 0.048). No difference was observed for colectomy. Duration of combotherapy longer than 9 months was inversely associated with clinical relapse (hazard ratio = 0.32 [95% confidence interval 0.15-0.70]). CONCLUSIONS: UC patients treated with combotherapy should maintain IFX and AZA for at least 9 months. Further studies are required to determine the optimal duration of combotherapy before stopping AZA in this situation.

Mesalazine 4 g daily given as prolonged-release granules twice daily and four times daily is at least as effective as prolonged-release tablets four times daily in patients with ulcerative colitis.

BACKGROUND: High doses of mesalazine usually result in an inconvenient dosage schedule and reduced compliance. The goal of this trial was to compare the effects of mesalazine 4 g daily given as prolonged-release granules in packets of 1 g with that of prolonged-release tablets of 0.5 g. METHODS: Two hundred twenty-seven patients with mild-to-moderate ulcerative colitis were randomized to treatment with two packets twice daily (Gr-b.i.d.), 1 packet four times daily (Gr-q.i.d.) or 2 tablets four times daily (Ta-q.i.d.) for 8 weeks. A disease activity index (ulcerative colitis disease activity index: UC-DAI) was calculated, and the granules were defined as noninferior to the tablets if the lower limit of the 95% CI for the differences was more than -1 UC-DAI score unit. RESULTS: Noninferiority of the granules compared with the tablets was demonstrated. The mean improvement in the UC-DAI in the treatment groups Gr-b.i.d., Gr-q.i.d., and Ta-q.i.d. were 3.2, 2.9, and 2.4, respectively; the proportion of complete responders in the three groups 39%, 37%, and 31%, respectively. There were no differences in side effects. CONCLUSION: Mesalazine 4 g daily given as prolonged-release granules twice and four times daily is at least as effective as prolonged-release tablets four times daily in patients with mild to moderate ulcerative colitis. The patients preferred the twice daily dosing.

Use of nutritional scores to predict clinical outcomes in chronic diseases.

Many hospitalized patients are malnourished, and the relationship between malnutrition and patient outcome is well established. To determine which patients are at nutritional risks, clinical scores are probably more accurate than using a single nutritional parameter. Among the numerous scores published, both the Prognostic Nutritional Index and the Subjective Global Assessment were prospectively validated. One is based on objective measurements, whereas the second is based on medical history and physical examination. The Nutritional Risk Index has been used in many studies including the "Veterans Study." The Mini Nutritional Assessment is a promising score for evaluating malnutrition in the elderly. The development of nutritional scores for use by nurses may facilitate screening of a large number of hospitalized patients.

Quality of life in long-term home enteral nutrition patients.

BACKGROUND AND AIMS: Few data are available on the quality of life of home enteral nutrition (HEN) patients. This study was designed to assess both the quality of life of long-term HEN patients and the evolution of quality of life after initiation of HEN. METHODS: Quality of life-related parameters were analysed in 38 patients (24M, 14F) aged 56 +/- 5 years who had been on HEN for more than 2 months (mean 25 +/- 5 months). Patients or close relatives were asked to answer a subjective assessment questionnaire, and patients with normal consciousness (n+ 24) answered the self-administered SF-36 and EuroQol questionnaires. RESULTS: Since the initiation of HEN, patients had spent 1.9 +/- 0.5% of the time in the hospital, in 54% of cases because of HEN-related complications. Analysis of the generic questionnaires revealed poorer quality of life parameters in comparison to a general population, although better results were sometimes observed in younger patients (under 45 years), patients without cancer, and patients with more than one care-giver. Nevertheless, the patients' subjective assessment of the changes in their quality of life since beginning HEN was generally good, with most patients reporting improved or stable mental and physical well-being. CONCLUSIONS: Quality of life is poor in HEN patients, but subgroups of patients who score better in some quality of life dimensions can be identified. Most patients describe an improvement in their quality of life following the initiation of HEN that needs to be confirmed by a prospective study.

Effects of refeeding by cyclic enteral nutrition on body composition: comparative study of elderly and younger patients.

Previous reports suggest that correcting the malnourished state may be more difficult in elderly people than in younger people. The aim of this study was to evaluate the effect of 21 days of cyclic enteral nutrition (CyEN) on nutritional and body composition parameters in elderly, compared with younger patients. Twenty-four patients younger than 65 years (mean age 50 years) and 26 patients 65 years of age and older (mean age 75 years) referred for refeeding, having lost at least 20% of their body weight or at least 10% in 3 months, were studied. All patients were ambulatory. Cyclic enteral nutrition was administered nocturnally via a nasogastric tube; in the daytime patients were allowed to eat normally and to walk. Resting energy expenditure was measured at day 0 by indirect calorimetry. Ten anthropometric and biological nutritional parameters and a global nutritional deficiency (GND) were measured at day 0 and 21. Body composition was measured at day 0 and 21 by bioelectric impedance analysis. Total energy intakes were 286% and 280% of resting energy expenditure in groups 1 and 2, respectively. Body weight, serum prealbumin, serum transferrin, 24 h urinary creatinine, and the GND (39.9% vs 23.3%; P < 0.01) improved significantly more in younger than in elderly patients. Fat free mass (3.9 vs 2.4 kg; P < 0.05) and body cell mass (2.7 vs 1.6 kg; P < 0.01) but not fat mass improved significantly more in younger than in elderly patients. In conclusion, 21 days refeeding by cyclic enteral nutrition with similar energy amounts is less effective to correct malnutrition in elderly than in younger patients.
