IntroductionThere is variability in the fecal calprotectin (FCP) cut‐off level for the prediction of ulcerative colitis (UC) disease activity and differentiation from irritable bowel disease (IBS‐D). The FCP cut‐off levels vary from country to country.AimsWe aimed to assess FCP as a marker of disease activity in patients with UC. We determined the optimal FCP cut‐off value for differentiating UC and IBS‐D.MethodsIn a prospective study, we enrolled 76 UC and 30 IBS‐D patients. We studied the correlation of FCP with disease activity/extent as well as its role in differentiating UC from IBS‐D. We also reviewed literature regarding the optimal FCP cut‐off level for the prediction of disease activity and differentiation from IBS‐D patients.ResultsSensitivity, specificity, positive predictive value, and negative predictive value of FCP (cut‐off level, 158 μg/g) for the prediction of complete mucosal healing (using Mayo endoscopic subscore) were 90, 85, 94.7, and 73.3%, respectively. Sensitivity, specificity, positive predictive value, and negative predictive value of FCP (cut‐off level, 425 μg/g) for the prediction of inactive disease (Mayo Score ≤ 2) were 94.3, 88.7, 86.2, and 95.4%, respectively. We also found a FCP cut‐off value of 188 μg/g for the differentiation of UC from IBS‐D.ConclusionsThe study reveals the large quantitative differences in FCP cut‐off levels in different study populations. This study demonstrates a wide variation in FCP cut‐off levels in the initial diagnosis of UC as well as in follow‐up post‐treatment. Therefore, this test requires validation of the available test kits and finding of appropriate cut‐off levels for different study populations.

Patients with novel coronavirus disease 2019 (COVID-19) are at significantly increased risk for mortality and morbidity. Current management remains supportive care, ranging from symptomatic outpatient management to full–intensive care support, including intravenous fluids, invasive, and non-invasive oxygen supplementation. In patients with septic shock, treatment with antibiotics and vasopressors are recommended to keep mean arterial pressure (MAP) ≥ 65 mm Hg and lactate < 2 mmol/L. Because of the lack of effectiveness and possible adverse effects, routine corticosteroids should be avoided unless they are indicated for another reason (exacerbation of asthma or chronic obstructive pulmonary disease [COPD], and septic shock in whom fluids and vasopressors do not restore hemodynamic stability). There is currently no sufficient evidence of efficacy of hydroxychloroquine/chloroquine, remdesivir, and other antivirals in the treatment or prevention of COVID-19. Limited evidence shows that COVID-19 convalescent plasma can be used as a treatment of COVID-19 without the occurrence of severe adverse events. Drug regulatory agencies granted an emergency-use authorization of chloroquine/hydroxychloroquine and remdesivir to treat patients when a clinical trial is not available or participation is not feasible. Chloroquine and hydroxychloroquine are associated with QT interval prolongation and life-threatening cardiac arrhythmia in patients with pre-existing cardiovascular disease. Guidelines are issued for use of convalescent plasma in patients with serious or immediately life-threatening COVID-19. Data from several ongoing randomized controlled trials will provide further evidence regarding the safety and efficacy of these drugs for the treatment of COVID-19.

Continuous infusion of terlipressin may be more effective than intermittent infusion to prevent treatment failure in patients with variceal bleeding. There is significant relationship between MELD-Na score [Odd ratio = 1.37 (95% CI-1.16 - 1.62), p-value < 0.001] and continuous infusion of terlipressin [Odd ratio = 0.18 (95% CI-0.037 - 0.91), p-value - 0.04] with treatment failure.

Background and AimData regarding the comparison of colonoscopic preparation regimens are still variable. We aimed to assess the adequacy and tolerability of two bowel preparation regimens for afternoon colonoscopy.MethodsIn a randomized, investigator‐blinded trial, two preparation regimens [4‐L split‐dose polyethylene glycol‐electrolytes (PEG‐ELS) and 2‐L PEG‐ELS plus bisacodyl) were compared in terms of bowel cleansing efficacy and adverse effects.ResultsThe mean (±SD) age (years) of the 4‐L split‐dose PEG‐ELS group (N = 147) and the 2‐L PEG‐ELS plus bisacodyl (N = 155) were 44.09 (±15.62) (M:F : 2:1) and 44.12 years (±15.61) (M:F : 1.7:1), respectively. Percentage of patients with excellent and good preparation was higher in the 4‐L split‐dose PEG‐ELS regimen compared with the 2‐L PEG‐ELS plus bisacodyl regimen (22.44 vs 17.41 and 44.21% vs 36.12%). Percentage of patients with fair and poor preparation was lower in 4‐L split‐dose PEG‐ELS regimen compared with the 2‐L PEG‐ELS plus bisacodyl regimen (21.08% vs 27.74% and 12.24% vs 18.70%). In comparison with the 2‐L PEG‐ELS plus bisacodyl group, the incidences of abdominal pain (11% vs 15%), bloating (9% vs 12.24%), nausea/vomiting (8.38% vs 9.52%), and sleep disturbance (11% vs 12%) were slightly more common in the 4‐L split‐dose PEG‐ELS group. There were no statistically significant differences between the two regimens with regard to bowel cleansing efficacy and adverse events.ConclusionsThe 2‐L PEG‐ELS plus bisacodyl (10 mg) preparation is as efficacious as the 4‐L split‐dose PEG‐ELS regimen for afternoon colonoscopy. Optimal preparation for colonoscopy can be achieved with the 2‐L PEG‐ELS plus bisacodyl regimen with slightly fewer adverse events and lower cost compared to the 4‐L split‐dose PEG‐ELS regimen.

AIMTo assess the vitamin D (VD) deficiency as a prognostic factor and effect of replenishment of VD on mortality in decompensated cirrhosis.METHODSPatients with decompensated liver cirrhosis were screened for serum VD levels. A total of 101 VD deficient patients (< 20 ng/mL) were randomly enrolled in two groups: Treatment group (n = 51) and control group (n = 50). Treatment group received VD treatment in the form of intramuscular cholecalciferol 300000 IU as loading dose and 800 IU/d oral as maintenance dose along with 1000 mg oral calcium supplementation. The VD level, clinical parameters and survival of both the groups were compared for 6-mo.RESULTSPrevalence of vitamin D deficiency (VDD) in decompensated CLD was 84.31%. The mean (SD) age of the patients in the treatment group (M:F: 40:11) and control group (M:F: 37:13) were 46.2 (± 14.93) years and 43.28 (± 12.53) years, respectively. Baseline mean (CI) VD (ng/mL) in control group and treatment group were 9.15 (8.35-9.94) and 9.65 (8.63-10.7), respectively. Mean (CI) serum VD level (ng/mL) at 6-mo in control group and treatment group were 9.02 (6.88-11.17) and 29 (23-35), respectively. Over the period of time the VD, calcium and phosphorus level was improved in treatment group compared to control group. There was non-significant trend seen in greater survival (69% vs 64%; P > 0.05) and longer survival (155 d vs 141 d; P > 0.05) in treatment group compared to control group. VD level had no significant association with mortality (P > 0.05). In multivariate analysis, treatment with VD supplement was found significantly (P < 0.05; adjusted hazard ratio: 0.48) associated with survival of the patients over 6-mo.CONCLUSIONVD deficiency is very common in patients of decompensated CLD. Replenishment of VD may improve survival in patients with decompensated liver cirrhosis.
