Early aggressive hydration is widely recommended for the management of acute pancreatitis, but evidence for this practice is limited. At 18 centers, we randomly assigned patients who presented with acute pancreatitis to receive goal-directed aggressive or moderate resuscitation with lactated Ringer's solution. Aggressive fluid resuscitation consisted of a bolus of 20 ml per kilogram of body weight, followed by 3 ml per kilogram per hour. Moderate fluid resuscitation consisted of a bolus of 10 ml per kilogram in patients with hypovolemia or no bolus in patients with normovolemia, followed by 1.5 ml per kilogram per hour in all patients in this group. Patients were assessed at 12, 24, 48, and 72 hours, and fluid resuscitation was adjusted according to the patient's clinical status. The primary outcome was the development of moderately severe or severe pancreatitis during the hospitalization. The main safety outcome was fluid overload. The planned sample size was 744, with a first planned interim analysis after the enrollment of 248 patients. A total of 249 patients were included in the interim analysis. The trial was halted owing to between-group differences in the safety outcomes without a significant difference in the incidence of moderately severe or severe pancreatitis (22.1% in the aggressive-resuscitation group and 17.3% in the moderate-resuscitation group; adjusted relative risk, 1.30; 95% confidence interval [CI], 0.78 to 2.18; P = 0.32). Fluid overload developed in 20.5% of the patients who received aggressive resuscitation and in 6.3% of those who received moderate resuscitation (adjusted relative risk, 2.85; 95% CI, 1.36 to 5.94, P = 0.004). The median duration of hospitalization was 6 days (interquartile range, 4 to 8) in the aggressive-resuscitation group and 5 days (interquartile range, 3 to 7) in the moderate-resuscitation group. In this randomized trial involving patients with acute pancreatitis, early aggressive fluid resuscitation resulted in a higher incidence of fluid overload without improvement in clinical outcomes.

Risk for severe COVID-19 increases with age. Different vaccination strategies are currently being considered, including those aimed at slowing down transmission and those aimed at providing direct protection to those most at risk. The objectives of the current study were i) to assess age-related incidence and survival between PCR-diagnosed COVID-19 cases (n = 61,993) in the Autonomous Community of Aragon from March to November 2020, and ii) to characterize age differences regarding the course of the disease in hospitalized patients in a tertiary university hospital. We found a similar incidence of COVID-19 in individuals between 10 and 79 years. Incidence increased in those over 80 years possibly because of the elevated transmission within the nursing homes. We observed a profound disparity among age groups; case fatality rates (CFRs) were near 0 in cases younger than 39 years throughout different waves. In contrast, there was an age-dependent and progressive increase in the CFRs, especially during the first pandemic wave. SARS-CoV-2 infection caused a more severe and rapid progression in older patients. The elderly required faster hospitalization, presented more serious symptoms on admission, and had a worse clinical course. Hospitalized older individuals, even without comorbidities, had an increased mortality risk directly associated with their age. Lastly, the existence of comorbidities dramatically increased the CFRs in the elderly, especially in males. The elevated incidence of COVID-19 and the vulnerability of the elderly call for their prioritization in vaccination and targeted prevention measures specifically focused on this aged population.

INTRODUCTION:The coexistence of HIV infection and inflammatory bowel disease (IBD) is uncommon. Data on the impact of HIV on IBD course and its management are scarce. The aim of this study was to describe the IBD phenotype, therapeutic requirements, and prevalence of opportunistic infections (OIs) in IBD patients with a coexistent HIV infection.METHODS:Case-control, retrospective study includes all HIV-positive patients diagnosed with IBD in the Nationwide study on genetic and environmental determinants of inflammatory bowel disease registry. Patients with positive HIV serology (HIV-IBD) were compared with controls (HIV seronegative), matched 1:3 by year of IBD diagnosis, age, sex, and type of IBD.RESULTS:A total of 364 patients (91 HIV-IBD and 273 IBD controls) were included. In the whole cohort, 58% had ulcerative colitis, 35% had Crohn's disease (CD), and 7% were IBD unclassified. The HIV-IBD group presented a significantly higher proportion of proctitis in ulcerative colitis and colonic location in CD but fewer extraintestinal manifestations than controls. Regarding treatments, nonbiological therapies (37.4% vs 57.9%; P = 0.001) and biologicals (26.4% vs 42.1%; P = 0.007), were used less frequently among patients in the HIV-IBD group. Conversely, patients with HIV-IBD developed more OI than controls, regardless of nonbiological therapy use. In the multivariate analysis, HIV infection (odds ratio 4.765, 95% confidence interval (CI) 2.48-9.14; P < 0.001) and having ≥1 comorbidity (OR 2.445, 95% CI 1.23-4.85; P = 0.010) were risk factors for developing OI, while CD was protective (OR 0.372, 95% CI 0.18-0.78; P = 0.009).DISCUSSION:HIV infection seems to be associated with a less aggressive phenotype of IBD and a lesser use of nonbiological therapies and biologicals but entails a greater risk of developing OI.

BackgroundMany studies have assessed different malnutrition screening tools in oncologic patients. However, very few have been carried out using the new GLIM criteria for malnutrition. The objective of our study is to compare the most recommended screening tools with respect to the new GLIM criteria for malnutrition in cancer patients.MethodsObservational, cross-sectional, and single-center study carried out at the Medical Oncology Department at the Lozano Blesa Hospital in Zaragoza. We recruited 165 patients with tumors of the upper-gastrointestinal-tract, colorectal, and head-and-neck region undergoing outpatient treatment. All of them received MST, MUST, Nutriscore, MNA and CONUT screening tools, as well as the GLIM diagnostic criteria, which was used as the gold standard.ResultsMNA-SF showed the best sensitivity (0.99) and lowest specificity while CONUT had the best specificity (0.89) and lowest sensitivity to detect cancer-related malnutrition. We observed high variability in the diagnostic capabilities of Nutriscore when tumor location was considered, reducing sensitivity in patients with colorectal cancer compared to those with tumors of the upper-gastrointestinal-tract or head-and-neck location (0.25, 0.83, and 0.91 respectively). The highest index of agreement between the screening tools was found between MST, MUST and Nutriscore tests. Regarding the GLIM criteria, the highest agreement index was presented by MUST tool (0.66), while CONUT presented the lowest (0.12).ConclusionsSelecting the screening tool according to the type of cancer and its location may allow us to optimize its use and increase its performance, exploiting the advantages of each of them in the different populations.

Obesity and inflammatory bowel disease (IBD) are two chronic conditions whose prevalence continues to rise globally. Emerging evidence suggests a bidirectional interplay between them, mediated by shared pathophysiological pathways. This narrative review explores the mechanisms Ilinking obesity to IBD development and progression, focusing on the role of adipose tissue dysfunction. Both diseases exhibit intestinal dysbiosis, low-grade systemic inflammation, and impaired epithelial barrier integrity, contributing to immune activation. Visceral adiposity, particularly mesenteric fat, acts as an immunometabolic organ producing cytokines and adipokines that may exacerbate intestinal inflammation. In Crohn’s disease, mesenteric fat expansion, or “creeping fat”, is associated with transmural inflammation, fibrosis, and luminal narrowing. Epidemiological data on obesity as a risk factor for IBD remain inconsistent due to methodological heterogeneity and confounders. Similarly, the impact of obesity on IBD outcomes, including disease activity, phenotype, and the need for surgery, is debated. While mesenteric surgical approaches like Kono-S anastomosis showed initial promise in reducing recurrence, recent randomized trials offer conflicting results. Finally, metabolic drugs such as statins, metformin, and GLP-1 receptor agonists have demonstrated anti-inflammatory properties with potential utility in IBD management. Prospective studies are warranted to elucidate the clinical significance of obesity and metabolic dysfunction in IBD and evaluate targeted therapeutic strategies.

The eradication of the hepatitis C virus (HCV) has revolutionized the hepatology paradigm, halting the progression of advanced liver disease in patients with chronic infection and reducing the risk of hepatocarcinoma. In addition, treatment with direct-acting antivirals can reverse the lipid and carbohydrate abnormalities described in HCV patients. Although HCV eradication may reduce the overall risk of vascular events, it is uncertain whether altered lipid profiles increase the risk of cerebrovascular disease in certain patients. We have conducted a review on HCV and lipid and carbohydrate metabolism, as well as new scientific advances, following the advent of direct-acting antivirals.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is associated with abnormal liver function tests. We hypothesized that early altered liver biochemistries at admission might have different clinical relevance than subsequent changes during hospitalization. A single-center retrospective study was conducted on 540 consecutive hospitalized patients, PCR-diagnosed with SARS-CoV-2. Liver test abnormalities were defined as the elevation of either gamma-glutamyltransferase (GGT), alanine aminotransferase (ALT), or aspartate aminotransferase (AST), above the upper limit of normality set by our laboratory. Linear mixed models (LMM) evaluated longitudinal associations, incorporating all available follow-up laboratory chemistries. By the end of the follow-up period, 502 patients (94.5%) were discharged (109 (20.5%) died). A total of 319 (64.3%) had at least one abnormal liver test result at admission. More prevalent were elevated AST (40.9%) and GGT (47.3%). Abnormalities were not associated with survival but with respiratory complications at admission. Conversely, LMM models adjusted for age and sex showed that longitudinal increases during hospitalization in ferritin, GGT, and alkaline phosphatase (ALP), as well as a decreased albumin levels, were associated with reduced survival. This dual pattern of liver damage might reconcile previous conflicting reports. GGT and ALP trajectories could be useful to determine who might need more surveillance and intensive care.

Background: There are conflicting studies reporting both an increase and a decrease in vitamin B12 (VB12) levels in non-alcoholic fatty liver disease (NAFLD). In this study, we aimed to dissect the effects of steatosis and fibrosis on VB12. Methods: This is a cross-sectional study including all patients with a vibration-controlled transient elastography (VCTE) performed at the Hospital Miguel Servet (Zaragoza, Spain) between 2019 and 2022 for a chronic liver disease and having a recent blood test for VB12 levels. Liver fibrosis was assessed by VCTE and hepatic steatosis by ultrasonography and/or through controlled attenuation parameter (CAP). Results: 1195 patients (NAFLD n = 441, other chronic liver disease n = 754) were included. Median age was 57 years, 53% female. Patients with NAFLD had lower levels of VB12 compared to the rest of chronic liver diseases (289 vs. 313 pg/mL, p < 0.001). A significant negative correlation was observed between VB12 levels and hepatic steatosis measured by CAP (r = −0.13, p < 0.001). A significant positive correlation was observed between VB12 levels and liver stiffness in patients with NAFLD in both sexes (men r = 0.31, p < 0.001 and women r = 0.15, p = 0.016). A significant association between VB12 levels and liver fibrosis in cirrhosis stage was observed in patients with NAFLD (OR 1.06, 95% CI, 1.025–1.098, p = 0.001). Conclusion: VB12 levels were lower with greater hepatic steatosis. In NAFLD, VB12 levels were lower compared to other chronic liver diseases but their levels increased with higher liver stiffness and in cirrhosis stage.

Background and Aims: Malnutrition is a condition that has a great impact on oncology patients. Poor nutritional status is often associated with increased morbidity and mortality, increased toxicity, and reduced tolerance to chemotherapy, among other complications. The recently developed GLIM criteria for malnutrition aim to homogenize its diagnosis, considering the baseline disease status. We aimed to evaluate the performance of these new criteria for the prediction of complications and mortality in patients with cancer. Methods: This work is a prospective, single-center study. All outpatients under active treatment for head and neck, upper gastrointestinal, and colorectal tumors between February and October 2020 were recruited. These patients were followed up for 6 months, assessing the occurrence of complications and survival based on GLIM diagnoses of malnutrition. Results: We enrolled 165 outpatients, 46.66% of whom were malnourished. During the 6-month follow-ups, patients with malnutrition (46.7%, according to GLIM criteria) had a ~3-fold increased risk of hospital admission (p < 0.001) and occurrence of severe infection (considered as those requiring hospitalization, intravenous antibiotics, and/or drainage by interventional procedures) (p = 0.002). Similarly, malnourished patients had a 3.5-fold increased risk of poor pain control and a 4.4-fold increased need for higher doses of opioids (both p < 0.001). They also had a 2.6-fold increased risk of toxicity (p = 0.044) and a 2.5-fold increased likelihood of needing a dose decrease or discontinuation of cancer treatment (p = 0.011). The 6-month survival of malnourished patients was significantly lower (p = 0.023) than in non-malnourished patients. Conclusions: Diagnoses of malnutrition according to the GLIM criteria in oncology patients undergoing active treatment predict increased complications and worse survival at 6-month follow-ups, making them a useful tool for assessing the nutritional status of oncology patients.

Background We lack predictors of response to biologics in the management of patients with inflammatory bowel disease (IBD). A recent study has shown a significant association between HLA-DQA1*05 carriers and the development of loss of response to anti-tumor necrosis factor (TNF) mediated by immunogenicity. Methods Retrospective single-center cohort study including IBD patients who had received anti-TNF therapy as a first biologic and whose HLA-DQA1*05 had been determined. Primary nonresponse and secondary failure (assessed by survival analysis) have been evaluated as well as safety outcomes. Results A total of 199 IBD patients (161 [81%] with Crohn’s disease and 38 [19%] with ulcerative colitis) were included. A total of 42.4% were HLA-DQA1*05 carriers and 60% received combination therapy at the start of anti-TNF treatment. Median follow-up was 24 (interquartile range, 11-66) months. No statistically significant differences were found in primary nonresponse to anti-TNF (89.3% vs 87.8%; P = .825), depending on HLA carriers and noncarriers. No differences in secondary loss of response according to HLA variant in any of the analyses performed (full cohort, according to IBD or anti-TNF type) were observed. Again, no differences were observed in patients treated with combination therapy. In terms of safety, no significant differences were found in the rate of infusion reactions or serious adverse events. Conclusion In our real-life cohort of IBD patients treated for the first time with anti-TNF, being an HLA-DQA1*05 carrier did not act as a predictor of response failure, either primary or secondary. The safety of anti-TNF treatment has also not been influenced by the variant. Lay Summary The HLA variant DQA1*05 has been identified as a risk factor for the development of antibodies to anti-tumor necrosis factor drugs. We observed that its presence has no impact on clinical outcomes, such as secondary loss of response. These data suggest that caution is required before making decisions based on this HLA variant.
