RESUMO
OBJECTIVES: Walled-off necrosis (WON) is a serious complication to necrotizing acute pancreatitis with a high morbidity and mortality. The aim of this study was to investigate the long-term changes in pancreatic function, metabolic function and body composition in patients with WON. MATERIAL AND METHODS: Observational study including patients with WON who underwent endoscopic transmural drainage and necrosectomy. Patients were prospectively evaluated at baseline, 3-6 months after discharge, and 12 months after discharge. Patients were characterized with fecal elastase, blood samples, computer tomography, dual energy X-ray absorptiometry and Lundh's test. RESULTS: The study includes 17 patients (11 men) with WON. The etiologies were gallstones (53%) alcohol intake (35%) and 12% had an unknown etiology. The body mass index (BMI) dropped during baseline and 3 months after discharge (p = .03) and increased 12 months after discharge (p = .002). Twelve months after discharge, 29% had mild exocrine insufficiency, 7% moderate insufficiency and 50% severe insufficiency based on the Lundh's test. Fecal elastase was <100 µg/g in 35% and <200 µg/g in 59% 12 months after discharge. Only, 24% required pancreatic enzyme substitution. Endocrine insufficiency developed in 24%. These patients also had exocrine insufficiency. CONCLUSIONS: A considerable proportion of patients with WON experience both endocrine and exocrine pancreatic insufficiency suggesting that long-term follow-up is needed in order to ensure adequate treatment.

PURPOSE: Malnutrition increases the risk of developing alcohol-related complications. The aim of this study was to describe nutrient intake, nutritional status and nutrition-related complications in a Danish population of outpatients with alcohol dependency. METHODS: This was a cross-sectional study with a 6-month follow-up enrolling persons with alcohol dependency (n = 80) admitted to a hospital-based outpatient clinic. Body mass index, the waist-to-hip ratio and handgrip strength (HGS) were measured, a 7-day food diary was collected, and biochemical testing was conducted. Dual-energy X-ray absorptiometry was performed to determine body composition and bone mineral density (BMD). RESULTS: In total, 64% of the patients with alcohol dependency had vitamin D insufficiency (25-OH-vit D <50 nmol/l). Compared with surveys of the general population, the patients with alcohol dependency had lower energy intake (p = 0.008), s-zinc levels (p < 0.001), s-magnesium levels (p = 0.02), Z-scores for BMD (lumbar spine, p = 0.03; total hip, p = 0.009) and HGS (p < 0.001). Osteopenia was observed in 52% of individuals, and overt osteoporosis was noted in 7%. Comparing baseline data with data from the follow-up (n = 30), we found a decrease in s-CRP (p = 0.002) and s-alanine amino transferase (p = 0.01) levels and an increase in s-parathyroid hormone levels (p = 0.02). CONCLUSIONS: Patients with alcohol dependency have an altered nutritional status and risk of complications, as evidenced by osteopenia/osteoporosis and reduced muscle strength. Treatment at an outpatient clinic improved the variables related to liver function, but no change was observed in nutritional status over time. These findings suggest that specific screening and targeted treatment regimens for nutritional deficits could be beneficial.

BACKGROUND & AIMS: Adequacy of nutritional support in intensive care patients is still a matter of investigation. This study aimed to relate mortality to provision, measured requirements and balances for energy and protein in ICU patients. DESIGN: Prospective observational cohort study of 113 ICU patients in a tertiary referral hospital. RESULTS: Death occurred earlier in the tertile of patients with the lowest provision of protein and amino acids. The results were confirmed in Cox regression analyses which showed a significantly decreased hazard ratio of death with increased protein provision, also when adjusted for baseline prognostic variables (APACHE II, SOFA scores and age). Provision of energy, measured resting energy expenditure or energy and nitrogen balance was not related to mortality. The possible cause-effect relationship is discussed after a more detailed analysis of the initial part of the admission. CONCLUSION: In these severely ill ICU patients, a higher provision of protein and amino acids was associated with a lower mortality. This was not the case for provision of energy or measured resting energy expenditure or energy or nitrogen balances. The hypothesis that higher provision of protein improves outcome should be tested in a randomised trial.
