Background and Aim: Achalasia cardia, a primary motility disorder of the esophagus, poses significant malnutrition risks. This study aims at comprehensively assessing the nutritional status in untreated achalasia patients, contrasting it with functional gastrointestinal disorders (FGIDs) cases and impact of per-oral endoscopic myotomy (POEM) on nutrition at one-year., Methods: We conducted a prospective study, including consecutive achalasia cases, from December 2021 to April 2022 at a tertiary care centre. Biochemical parameters, anthropometry, subjective global assessment (SGA) and malnutrition universal screening tool were used for nutritional assessment. Cases diagnosed with FGIDs served as controls., Results: As many as 118 cases (41.2 ± 13.9 years, 61% males) with achalasia and 200 controls (43.4 ± 11.9 years, 69% males) were included in the study. Sub-types of achalasia included type I (16.9%), II (76.3%) and III (6.8%). Overall, 38.1% and 6.8% cases were moderately and severely malnourished, respectively. As compared to controls, cases with achalasia had lower pre-albumin (19.4 vs. 25.2; p = 0.001), serum calcium (p = 0.012), vitamin D (p = 0.001), serum iron (p = 0.001), triceps fold thickness (p = 0.002) and hand-grip strength (p = 0.001). On univariate analysis, type-I achalasia, body mass index, % weight loss, lower esophageal sphincter pressures and Eckardt scores were predictors of malnourishment (SGA). On multivariate analysis, type of achalasia, mid arm circumference and low body mass index were significant predictors of malnourishment in cases with achalasia. There was significant improvement in the nutritional status after POEM at one-year follow-up., Conclusion: Achalasia patients demonstrate a notably higher risk of malnutrition compared to individuals with FGIDs. Nutritional status significantly improves after POEM. (NCT05161923)., Competing Interests: Declarations.

Background: RCTs that have shown improvement in coefficient of fat absorption with pancreatic enzyme replacement therapy (PERT) have seldom evaluated the impact on overall nutritional status., Objective: In this study we evaluated factors responsible for persistence of malnutrition after PERT., Methods: In this cross-sectional observational study, patients were enrolled based on predefined enrolment criteria. Patients were divided into those taking PERT regularly (Group A), irregularly (Group B) and not taking (Group C) for at least 3 months. Comprehensive evaluation of anthropometric measurements, nutritional assessment and dietary intake was performed. Malnutrition was measured using the Subjective Global Assessment (SGA) tool. Relationship between PERT status, dietary intake and nutritional status were evaluated using standard statistical methods. Logistic regression was performed to identify factors associated with persistence of malnutrition after PERT., Results: 377 patients with CP and 50 controls were included. 95 (25.2%) patients with CP were in Group A, 106 (28.1%) in Group B and 176 (46.7%) in Group C. 130 (34.5%) patients were malnourished, of which 76 (58.5%) were continuing PERT. There were no differences in clinical and biochemical nutritional markers between Groups A, B, and C. Calorie deficit and daily intake of calorie, protein, carbohydrates and fats were not different between those with and without PERT, but was significantly less in those with malnutrition. Logistic regression demonstrated inadequate dietary intake as independent risk factor for persistence of malnutrition., Conclusion: Even though PERT is effective in PEI, comprehensive nutritional assessment, personalized nutritional counselling and therapy along with PERT is mandatory., (Copyright © 2020 IAP and EPC.

Background: In severe acute pancreatitis (AP), intravenous glutamine has been shown to reduce the rate of complications, hospital stay, and mortality. In the present randomized trial, we aimed to evaluate the effect of enteral glutamine supplementation on clinical outcomes, gut permeability, systemic inflammation, oxidative stress, and plasma glutamine levels in patients with severe and predicted severe AP., Methods: Patients with AP admitted within 72 h of onset of symptoms were included. The primary outcome measure was development of infected pancreatic and peri-pancreatic necrosis and in-hospital mortality. High-sensitivity C-reactive protein (HS-CRP) and interleukin-6 (IL-6) were evaluated as markers of inflammation; plasma thiobarbituric acid reactive substances (TBARS) and activities of serum superoxide dismutase and glutathione peroxidase were determined to evaluate oxidative stress; serum polyethylene glycol (PEG) was tested for intestinal permeability; subjective global assessment (SGA) was used for nutritional assessment, and an improvement in organ function was measured by the Modified Marshall score. Intention-to-treat analysis was used. A p-value of < 0.05 was considered statistically significant., Results: After power calculation, we enrolled 18 patients in the glutamine and 22 in the control arm. There was no significant improvement in the development of infected necrosis and in-hospital mortality between the groups. Improvement in Modified Marshall score was observed in a higher proportion of patients receiving glutamine (15 [83.3%] vs. 12 [54.5%]; p = 0.05). Plasma glutamine levels improved more in glutamine-treated group (432.72 ± 307.83 vs. 618.06 ± 543.29 μM/L; p = 0.004), while it was lower in controls (576.90 ± 477.97 vs. 528.20 ± 410.45 μM/L; p = 0.003). PEG level was lower after glutamine supplementation (39.91 ± 11.97 vs. 32.30 ± 7.39 ng/mL; p = 0.02). Statistically significant reduction in IL-6 concentration was observed in the glutamine group at the end of treatment (87.44 ± 7.1 vs. 63.42 ± 33.7 μM/L; p = 0.02)., Conclusions: Despite absence of improvement in infected necrosis and in-hospital mortality, enteral glutamine supplementation showed improvement in gut permeability, oxidative stress, and a trend towards improvement in organ function as depicted by improvement in the Modified Marshall score., Trial Registration: NCT01503320.
