Coconut Water Induces Clinical Remission in Mild to Moderate Ulcerative Colitis: Double-blind Placebo-controlled Trial.

BACKGROUND & AIMS: Coconut water (CW) is anti-inflammatory, can manipulate the gut microbiome, and is a rich source of potassium. Gut microbiome modulation improves outcomes in ulcerative colitis (UC), and potassium possesses in vitro anti-inflammatory property. We evaluated the effect of CW as an adjunct therapy for patients with mild-moderate UC. METHODS: This single-center, double-blind, placebo-controlled trial randomized patients with mild to moderate (Simple Clinical Colitis Activity Index [SCCAI]: 3-9) endoscopically active UC (Ulcerative Colitis Endoscopic Index of Severity [UCEIS] >1) in 1:1 ratio to CW + standard medical therapy (SMT) vs placebo + SMT. Four hundred mL of CW was administered for 8 weeks. Primary outcome measure was clinical remission (SCCAI ≤2), and secondary outcome measures were clinical response (SCCAI decline ≥3) and adverse events at 8 weeks. Microbiome was analyzed at baseline and 8 weeks. RESULTS: Of 121 patients screened, 95 were included for modified intention to treat analysis (CW, n = 49; placebo, n = 46) (mean age, 37.2 ± 11.2 years; males, 54.1%; disease duration, 48 months [interquartile range (IQR), 24-90 months]; pancolitis, 26.1%; SCCAI, 5 [IQR, 4-6]; UCEIS, 4 [IQR, 3-5]). Clinical response (57.1% vs 28.3%; odds ratio [OR], 3.4; 95% confidence interval [CI], 1.4-7.9; P = .01), remission (53.1% vs 28.3%; OR, 2.9; 95% CI, 1.2-6.7; P = .02), and proportion of patients with fecal calprotectin (FCP) <150 µg/g (30.6% vs 6.5%; OR, 6.3; 95% CI, 1.7-23.6; P = .003) were significantly higher in CW. The relative abundance of bacterial taxa that had a significant or trend towards negative correlation with SCCAI, UCEIS, or FCP increased at 8 weeks in CW, and this effect was independent of disease activity and dietary fiber. Adverse events were comparable, and no patient developed hyperkalemia. CONCLUSIONS: CW was more effective than placebo for induction of clinical remission in patients with mild to moderate UC. The trial was prospectively registered on Clinical Trials Registry of India (ctri.nic.in, Number: CTRI/2019/03/01827).

Long-term Gastrointestinal Sequelae Following COVID-19: A Prospective Follow-up Cohort Study.

BACKGROUND & AIMS: Coronavirus disease 2019 (COVID-19) is associated with long-term gastrointestinal sequelae; however, prospective longitudinal data are sparse. We prospectively studied the frequency, spectrum, and risk factors of post infection functional gastrointestinal disorders/disorders of gut-brain interaction (PI-FGID/DGBI) after COVID-19. METHODS: Three hundred twenty cases with COVID-19 and 2 control groups, group A, 320 healthy spouses/family controls, and group B, 280 healthy COVID serology-negative controls, were prospectively followed up at 1, 3, and 6 months by using validated Rome IV criteria to evaluate the frequency of PI-FGID/DGBI. RESULTS: Of 320 cases, at 1 month 36 (11.3%) developed FGID symptoms. Persistent symptoms were noted in 27 (8.4%) at 3 months and in 21 (6.6%) at 6 months. At 3 months, 8 (2.5%) had irritable bowel syndrome, 7 (2.2%) had functional diarrhea, 6 (1.9%) had functional dyspepsia, 3 (0.9%) had functional constipation, 2 (0.6%) had functional dyspepsia-IBS overlap, and 1 (0.3%) had functional abdominal bloating/distention. Among symptomatic individuals at 3 months, 8 (29.6%) were positive for isolated carbohydrate malabsorption, 1 (3.7%) was positive for post infection malabsorption syndrome, and 1 (3.7%) was positive for intestinal methanogen overgrowth. None of the healthy controls developed FGID up to 6 months of follow-up (P < .01). Predictive factors at 3 and 6 months were severity of infection (P < .01) and presence of gastrointestinal symptoms at the time of infection (P < .01). CONCLUSIONS: COVID-19 led to significantly higher number of new onset PI-FGID/DGBI compared with healthy controls at 3 and 6 months of follow-up. If further investigated, some patients can be diagnosed with underlying malabsorption.

Serum albumin is the strongest predictor of anti-tumor necrosis factor nonresponse in inflammatory bowel disease in resource-constrained regions lacking therapeutic drug monitoring.

BACKGROUND/AIMS: Evidence on predictors of primary nonresponse (PNR), and secondary loss of response (SLR) to anti-tumor necrosis factor (anti-TNF) agents in inflammatory bowel disease is scarce from Asia. We evaluated clinical/biochemical/molecular markers of PNR/SLR in ulcerative colitis (UC) and Crohn's disease (CD). METHODS: Inflammatory bowel disease patients treated with anti-TNF agents (January 2005-October 2020) were ambispectively included. Data concerning clinical and biochemical predictors was retrieved from a prospectively maintained database. Immunohistochemistry for expression of oncostatin M (OSM), OSM receptor (OSM-R), and interleukin-7 receptor (IL-7R) were done on pre anti-TNF initiation mucosal biopsies. RESULTS: One-hundred eighty-six patients (118 CD, 68 UC: mean age, 34.1±13.7 years; median disease duration at anti-TNF initiation, 60 months; interquartile range, 28-100.5 months) were included. PNR was seen in 17% and 26.5% and SLR in 47% and 28% CD and UC patients, respectively. In CD, predictors of PNR were low albumin (P<0.001), postoperative recurrence (P=0.001) and high IL-7R expression (P<0.027) on univariate; and low albumin alone (hazard ratio [HR], 0.09; 95% confidence interval [CI], 0.03-0.28; P<0.001) on multivariate analysis respectively. Low albumin (HR, 0.31; 95% CI, 0.15-0.62; P=0.001) also predicted SLR. In UC, predictors of PNR were low albumin (P<0.001), and high C-reactive protein (P<0.001), OSM (P<0.04) and OSM-R (P=0.07) stromal expression on univariate; and low albumin alone (HR, 0.11; 95% CI, 0.03-0.39; P=0.001) on multivariate analysis respectively. CONCLUSIONS: Low serum albumin at baseline significantly predicted PNR in UC and PNR/SLR in CD patients. Mucosal markers of PNR were high stromal OSM/OSM-R in UC and high IL-7R in CD patients.

Development and Validation of a Smartphone Application for Telenutrition in Patients with Inflammatory Bowel Disease.

The use of smartphone-based applications as a telenutrition tool could redefine the nutritional management of IBD. We developed and validated a digital health platform in the form of a smartphone application for the nutritional assessment of IBD patients. Our team of gastroenterologists and dieticians at the All-India Institute of Medical Sciences, New Delhi developed a smartphone application titled IBD NutriCare, which was made available in both Android and iOS interfaces in English and seven other Indian languages. The application includes >650 Indian recipes and provides subjective global assessment and IBD clinical activity scores in a patient-friendly manner. The utility of the smartphone app was validated in comparison with the traditional 24-h dietary recall method. A total of 49 IBD patients were enrolled in the study. The mean difference in energy intake between the two dietary assessment methods was −4.776 kJ (95% LOA, range −417.916−408.365 kJ). A total of 94% of patients found the smartphone application convenient and acceptable in comparison to the recall method for dietary assessment. Bland−Altman plots showed a good level of agreement for nutrients and food groups between the two methods. Telenutrition in the form of a smartphone application helps in real-time tracking of dietary details of IBD patients, thus making appropriate interventions and large-scale data acquisition feasible.

Combined or High Dose Immunosuppression in Inflammatory Bowel Disease patients who are NUDT15 Homozygous Harbors Risk of Developing Invasive Fungal Infections: A Case Series.

NUDT15 homozygous mutations predispose patients to severe leucopenia, which invites risk of disseminated fungal infections when high doses or a combination of immunosuppressives are administered in this patient population.
