ABSTRACT

BACKGROUND: Coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 virus most commonly presents with respiratory symptoms. While gastrointestinal (GI) manifestations either at presentation or during hospitalization are also common, their impact on clinical outcomes is controversial. Some studies have described worse outcomes in COVID-19 patients with GI symptoms, while others have shown either no association or a protective effect. There is a need for consistent standards to describe GI symptoms in COVID-19 patients and to assess their effect on clinical outcomes, including mortality and disease severity. AIM: To investigate the prevalence of GI symptoms in hospitalized COVID-19 patients and their correlation with disease severity and clinical outcomes. METHODS: We retrospectively reviewed 601 consecutive adult COVID-19 patients requiring hospitalization between May 1-15, 2020. GI symptoms were recorded at admission and during hospitalization. Demographic, clinical, laboratory, and treatment data were retrieved. Clinical outcomes included all-cause mortality, disease severity at presentation, need for intensive care unit (ICU) admission, development of acute respiratory distress syndrome, and need for mechanical ventilation. Multivariate logistic regression model was used to identify independent predictors of the adverse outcomes. RESULTS: The prevalence of any GI symptom at admission was 27.1% and during hospitalization was 19.8%. The most common symptoms were nausea (98 patients), diarrhea (76 patients), vomiting (73 patients), and epigastric pain or discomfort (69 patients). There was no difference in the mortality between the two groups (6.21% vs 5.5%, P = 0.7). Patients with GI symptoms were more likely to have severe disease at presentation (33.13% vs 22.5%, P < 0.001) and prolonged hospital stay (15 d vs 14 d, P = 0.04). There was no difference in other clinical outcomes, including ICU admission, development of acute respiratory distress syndrome, or need for mechanical ventilation. Drugs associated with the development of GI symptoms during hospitalization were ribavirin (diarrhea 26.37% P < 0.001, anorexia 17.58%, P = 0.02), hydroxychloroquine (vomiting 28.52%, P = 0.009) and lopinavir/ritonavir (nausea 32.65% P = 0.049, vomiting 31.47% P = 0.004, and epigastric pain 12.65% P = 0.048). In the multivariate regression analysis, age > 65 years was associated with increased mortality risk [odds ratio (OR) 7.53, confidence interval (CI): 3.09-18.29, P < 0.001], ICU admission (OR: 1.79, CI: 1.13-2.83, P = 0.012), and need for mechanical ventilation (OR: 1.89, CI:1.94-2.99, P = 0.007). Hypertension was an independent risk factor for ICU admission (OR: 1.82, CI:1.17-2.84, P = 0.008) and need for mechanical ventilation (OR: 1.66, CI: 1.05-2.62, P = 0.028). CONCLUSION: Patients with GI symptoms are more likely to have severe disease at presentation; however, mortality and disease progression is not different between the two groups.

ABSTRACT

AIM: We aim to compare 20 noninvasive fibrosis scores (NIFS), derived from routine blood tests, for predicting significant liver-related adverse events (SLRE) in patients with chronic hepatitis C (CHC) after anti-viral treatment (AVT) with the goal to identify independent predictors for these outcomes. METHODS: From 1605 patients who received AVT (pegylated interferon and ribavirin) from January 2002 to June 2014, 20 NIFS were calculated from routine blood tests prior to AVT. Areas under the receiver-operating characteristic curve (AUROC) were calculated for each of these NIFS for predicting non-response to AVT and development of SLRE on follow-up. RESULTS: Mean age was 41.9 ± 9.7 years, and patients were predominantly genotype 4 (65%). After AVT, there were 1089 (67.8%) responders, 482 (30%) non-responders and 34 (2.1%) relapsers. After median follow-up of 6580.5 patient-years, 60 (3.8%) had SLRE, 52 (3.2%) had decompensation, and 11 (0.7%) had hepatocellular carcinoma (HCC). The predictive accuracy of NIFS and liver biopsy (LB) for non-response to AVT was low. FIB-4, FibroQ and King score showed high accuracy for predicting adverse events. For predicting decompensation, HCC and SLRE, FibroQ (0.881), King score (0.905) and FibroQ (0.877) had the highest AUROC, respectively. On multivariate analysis, independent predictors for treatment non-response (age, ALT, GGT, platelet count), HCC (albumin, GGT) and SLRE (albumin, GGT, platelet count) were identified. CONCLUSIONS: Some simple pretreatment blood parameters and NIFS showed high accuracy for predicting development of SLRE post treatment. Application of these simple scores can improve assessment of long-term liver prognosis for CHC.

ABSTRACT

BACKGROUND: The aim of this study was to compare noninvasive biomarkers, FibroTest and ActiTest in predicting fibrosis stage and inflammation grade in chronic hepatitis C (CHC) patients with liver biopsy (LB). METHODS: In 107 patients with CHC, levels of six serum biomarkers (alanine aminotransferase, γ-glutamyl transpeptidase, total bilirubin, haptoglobin, apolipoprotein, α-2 macroglobulin) were determined at the time of LB. LB was evaluated by Metavir score for fibrosis and inflammation. Voluntary blood donors (n=106) were taken as controls for the study. RESULTS: Fibrosis estimated by Fibrotest was significantly higher in patients compared to control group. The observed area under the receiver operating characteristic curve (AUROC) for advanced fibrosis (F3, F4) adjusted according to the observed difference between advanced and non-advanced fibrosis prevalence (DANA) was 0.80 (0.69-0.88) and the AUROC for cirrhosis (F4) was 0.94 (0.86-0.98). ActiTest AUROC for moderate to severe activity (A2A3) was 0.72 (0.61-0.81), and for severe activity (A3) was 0.88 (0.78-0.93). The diagnostic values in the group of good quality biopsy (n=41) showed Fibrotest AUROC (DANA-adjusted): for advanced fibrosis 0.90 (0.72-0.99); for cirrhosis 0.93 (0.76-0.98); and ctiTest AUROC: for moderate/severe activity 0.86 (0.67-0.94); and for severe activity 0.90 (0.76-0.93). There was good concordance between FibroTest and LB (with discordance for two or more stages in <20% for advanced fibrosis and <10% for cirrhosis) and between ActiTest and LB. Specificity for FibroTest and ActiTest in the control population were 95% and 100% respectively. CONCLUSIONS: Fibrotest and ActiTest had high observed and standardized diagnostic values for predicting fibrosis and activity respectively.

ABSTRACT

Endoscopic ultrasound (EUS) guided drainage of pancreatic fluid collections (PFC) has become increasingly popular and become first line management option in many centers. Use of therapeutic echoendoscopes has greatly increased the applicability of EUS guided transmural drainage. Drainage is indicated in symptomatic PFCs, PFC related infection, bleed, luminal obstruction, fistulization and biliary obstruction. EUS guided transmural drainage of PFCs is preferred in patients with non bulging lesions, portal hypertension, bleeding tendency and in those whom conventional drainage has failed. In the present decade significant progress has been made in minimally invasive endoscopic techniques. There are newer stent designs, access devices and techniques for more efficient drainage of PFCs. In this review, we discuss the EUS guided drainage of PFCs in acute pancreatitis.

ABSTRACT

Severe ulcerative colitis can be associated with bowel perforation. Bowel perforation rarely leads on to abdominal wall and scrotal wall emphysema. Bowel perforation in such cases can be spontaneous or iatrogenic (colonoscopy-related). We report a rare scenario where a patient presented with abdominal wall and scrotal emphysema after topical corticosteroid enema-induced traumatic rectal perforation. Topical corticosteroids were stopped immediately after identification of rectal perforation. The patient was managed conservatively with intravenous antibiotics. With this report we intend to sensitise clinicians and topical enema manufacturers regarding this rare complication.
