P224 Regular physical activity on IBD patients: impact on IBD natural history and related comorbidities

Abstract Background Regular physical activity (PA) has a potential antioxidant and anti-inflammatory effect that is mainly exerted on adipose tissue, skeletal muscle, and the immune and cardiovascular systems. Thus, PA is known to be beneficial in different pro-inflammatory conditions. Nevertheless, data on the role of PA in IBD patients is scarce. The aim of our study is to analyse the association of PA with clinical outcomes in IBD patients. Methods Cross-sectional prospective study including all consecutive IBD patients attended at a university hospital was performed. Data on physical activity was recorded through the International Physical Activity Questionnaire (IPAQ). Metabolic Equivalent Task (MET) hours per week were calculated according to the combination of walking, moderate-intensity or vigorous intensity activity, and patients were categorized into low, moderate or high PA according to a previously validated method. Data on IBD phenotype, activity indexes, natural history, current and past treatments, together with liver evaluation, and history of cardiovascular risk factors were also collected. Results 831 patients were included in the study. Study flow chart is depicted in figure and clinical characteristics in table 1. IBD patients with a low or moderate PA showed a tendency to a higher proportion of IBD-related complications and higher scores in disease activity indexes than those with high PA. PA was strongly associated to the metabolic profile. Patients with a low/moderate PA were more frequently obese, hypertense, diabetic and had dyslipidaemia. Regarding liver disease, PA was significantly associated to the presence of non-alcoholic fatty liver disease (NAFLD), but not with advanced liver fibrosis. Conclusion Insufficient PA can negatively impact clinical outcomes in IBD patients, probably not because of a direct effect on IBD-pathogenesis, but due to its strong association with cardiovascular risk factors and NAFLD.

Cortical Response

Cardiovascular fitness is linked to better executive functions, preserved gait speed, and efficient cortical activity. Older adults with cardiovascular risk factors (CVRFs) typically show poor cognitive performance, low physical fitness, and altered brain functioning compared with healthy individuals. In the current study, the impact of regular physical activity on cognition, locomotion, and brain functions was explored in a cohort of older adults with low or high CVRFs. Cortical activation of the frontal areas was investigated using functional Near-Infrared Spectroscopy (fNIRS) at baseline, at 6 months and at 12 months. Evoked cortical response and behavioral performance were assessed using the dual-task walking paradigm, consisting of three conditions: single cognitive task (2-back task), single walking task (walking), and dual-task (2-back whilst walking). Results show greater task-related cortical response at baseline in individuals with high CVRFs compared to those with low CVRFs. Moreover, participants with high CVRFs benefitted the most from participating in regular physical activity, as their cortical response decreased at the 12-month follow-up and became comparable to that of participants with low CVRFs. These changes were observed in conjunction with improved cognitive performance and stable gait speed throughout the 12-month period in both groups. Our findings provide evidence that participation in regular physical activity may be especially beneficial in individuals with CVRFs by promoting brain and cognitive health, thus potentially contributing to prevention of cognitive decline. Future research may explore whether such effects are maintained in the long-term in order to design ad-hoc interventions in this specific population.

Bcakgrounds: Non alcoholic fatty liver disease (NAFLD) has been linked independently to cardiovascular disease (CVD) but It is largely unknown if such a relationship between NAFLD and CVD risk relates to severity of liver disease or if it is independent of other potential confounding factors Methods: This study included 30,172 subjects. Based on the presence or absence of steatosis on ultrasound and serum alanine aminotransferase (ALT), subjects were divided into controls, an increased serum ALT group without steatosis and a group with presumed nonalcoholic fatty liver disease (NAFLD), which included a steatosis alone group and a group with presumed non alcoholic steatohepatitis (NASH) with steatosis and an elevated ALT. Results: The odds ratio for 10-year risk by total Framingham risk scores ≥10% was 5.3 times higher in NASH groups. The prevalence of diabetes, hypertension, elevated CRP and metabolic syndrome were all increased up to 15 fold over controls, independent of age, BMI, smoking and exercise habits. Overall CVD risk was significantly greater in NASH than in either steatosis or raised ALT alone. Conclusion: Young, non-obese subjects with NAFLD are at significantly increased CVD risk, especially those with NASH. As well as specific therapy for liver disease, a diagnosis of NAFLD should lead to targeted risk assessment and risk factor modification. Table 1.

Abstract Background Although many studies on non-alcoholic fatty liver disease (NAFLD) are underway worldwide, and several existing studies have investigated the association between NAFLD and cardiovascular risk factors, studies comparing NAFLD and alcoholic fatty liver disease (AFLD) are scarce. This study aimed to evaluate differences between the incidence of cardiovascular risk factors and metabolic syndrome in NAFLD and AFLD. Methods A retrospective analysis of 913 patients who underwent abdominal computed tomography (CT) was performed to compare the incidence of cardiovascular risk factors and metabolic syndrome between NAFLD and AFLD. Subjects were divided into three groups based on criteria: healthy (n = 572), NAFLD (n = 295), and AFLD (n = 46). The healthy group had no liver disease. NAFLD was defined as fatty liver diagnosed on CT and drinking less than 140 g/week for men or 70 g/week for women. AFLD was defined as fatty liver diagnosed on CT and drinking more than 140 g/week for men or 70 g/week for women. We compared the incidence of cardiovascular risk factors and metabolic syndrome between the three groups. The relationship between each group and the metabolic syndrome risk was analyzed through multivariate logistic regression analysis. Results No significant differences in several cardiovascular risk factors were observed between the NAFLD and AFLD groups. Upon analyzing the metabolic syndrome status in each group after making appropriate adjustments, the odds ratios (ORs) in the NAFLD (OR = 2.397, P = 0.002) and AFLD groups (OR = 4.445, P = 0.001) were found to be significantly higher than that in the healthy group; the incidence rate of metabolic syndrome was similar in the NAFLD and AFLD groups. Conclusions Both the NAFLD and AFLD groups had more cardiovascular risk factors and higher metabolic syndrome risk than the healthy group. Thus, the prevention of fatty liver disease, regardless of the specific type, should involve the identification of cardiovascular and metabolic syndrome risk factors. If abdominal CT reveals a fatty liver, whether NAFLD or AFLD, the risk of cardiovascular disease and metabolic syndrome should be assessed.
