RESUMEN

Pancreatic fibrosis is characterized by the activation of pancreatic stellate cells leading to the expression of smooth muscle actin (α-SMA). Normal pancreatic tissue has predominantly quiescent stellate cells in periductal and perivascular locations, which do not express α-SMA. We aimed at studying the immunohistochemistry (IHC) expression pattern of α-SMA, platelet-derived growth factor (PDGF-BB) and transforming growth factor (TGF-ß) in the resected specimen of chronic pancreatitis. Twenty biopsies from resected specimens of patients with chronic pancreatitis were included. The expression was measured in comparison to positive control biopsies (breast carcinoma for PDGF-BB and TGF-ß and appendicular tissue for α-SMA) and scored based on a semi-quantitative system based on staining intensity. The percentage of positive cells was used for objective scoring, which ranged from 0 to 15. The scoring was done separately for acini, ducts, stroma and islet cell. All patients had undergone surgery for refractory pain and the median duration of symptoms was 48 months. On IHC, α-SMA was not expressed in the acini, ducts or islets, but had high expression in the stromal regions (vs. acini, ducts and islet, p < 0.05), TGF-ß1 was also expressed maximally in islet cells; however, the distribution among all locations was statistically similar. α-SMA expression in the pancreatic stroma is an indicator of the concentration of activated stellate cells in the stroma, a site for genesis of fibrosis under the influence of growth factors in the local milieu.

RESUMEN

Immunoproliferative small intestinal disease (IPSID) is an uncommon disease of the small intestine. There is a similarity in the clinical presentations of enteropathic diseases, including celiac disease, tropical sprue, IPSID, and Whipple's disease. A differentiation between them is based on the use of a highly specific serological test for celiac disease and specific histological characteristics. We found that IgA-anti-tissue transglutaminase antibody (IgA-tTG Ab) is falsely elevated in a subset of patients with IPSID. The levels of IgA-tTG Ab fall with the treatment of IPSID. The healthcare professional should be aware of the conditions that lead to a false-positive anti-tTG Ab. Intestinal mucosal biopsies even in the presence of anti-tTG Ab should be done in endemic regions as they provide an opportunity for making a diagnosis of alternative and uncommon diseases before the diagnosis of celiac disease.

RESUMEN

A 34-year-old male visited our hospital with complaints of recurrent episodes of altered behavior since past 6 months along with difficulty in walking since past 3 months. He was diagnosed of chronic liver disease in the past. Examination revealed spasticity and brisk deep tendon reflexes in both the lower limbs. His blood investigations and spinal cord imaging was normal. Based on his clinical features, a possibility of portosystemic shunting leading to portosystemic encephalopathy (PSE) and shunt myelopathy was suspected. A computed tomography portography showed a recanalized paraumblical vein draining portal blood into external iliac veins. Patient underwent shunt occlusion (Figure- 2). One month after the procedure, while there was no recurrence of symptoms of PSE, those of myelopathy remained unchanged. Shunt myelopathy is a rare complication of spontaneous or iatrogenic portosystemic shunts. Unlike PSE, the management of shunt myelopathy is uncertain due to limited evidence. Limited evidence suggests reversal of myelopathy after early shunt occlusion, highlighting the irreversible changes that may set in spinal cord due to delayed diagnosis. Our case highlights an important but a rare complication of portosystemic shunting in chronic liver disease which should be kept in mind if these patients develop symptoms attributable to spinal cord disease.

RESUMEN

BACKGROUND/AIMS: Intestinal tuberculosis (ITB) and Crohn's disease (CD) frequently present with a diagnostic dilemma because of similar presentation. Interferon-gamma release assay (IGRA) has been used in differentiating ITB from CD, but with sparse reports on its diagnostic accuracy in tuberculosis endemic regions and this study evaluated the same. METHODS: Patients with definitive diagnosis of ITB (n=59) or CD (n=49) who underwent IGRA testing (n=307) were retrospectively included at All India Institute of Medical Sciences, New Delhi (July 2014 to September 2021). CD or ITB was diagnosed as per standard criteria. IGRA was considered positive at >0.35 IU/mL. Relevant data was collected and IGRA results were compared between ITB and CD to determine its accuracy. RESULTS: Among 59 ITB patients (mean age, 32.6±13.1 years; median disease duration, 1 year; male, 59.3%), 24 were positive and 35 tested negative for IGRA. Among 49 CD patients (mean age, 37.8±14.0; median disease duration, 4 years; male, 61.2%), 12 were positive and 37 tested negative for IGRA. Hence, for diagnosing ITB, IGRA showed a sensitivity, specificity, positive and negative predictive values of 40.68%, 75.51%, 66.67%, and 51.39%, respectively. The area under the curve of IGRA for ITB diagnosis was 0.66 (95% confidence interval, 0.55-0.75). In a subset (n=64), tuberculin skin test (TST) showed sensitivity, specificity, positive and negative predictive values of 64.7%, 73.3%, 73.3%, and 64.71%, respectively. IGRA and TST were concordant in 38 (59.4%) patients with κ=0.17. CONCLUSIONS: In a tuberculosis endemic region, IGRA had poor diagnostic accuracy for differentiating ITB from CD, suggesting a limited value of IGRA in this setting.

RESUMEN

INTRODUCTION: Limited data exist on long-term outcomes of patients with compensated cirrhosis presenting with acute variceal bleeding (AVB) as an index and lone decompensating event. This study aimed to evaluate the incidence of further decompensation, survival, and risk factors of mortality in these patients. METHODS: Patients with otherwise compensated cirrhosis presenting with AVB as their index decompensating event (n = 463) were analyzed in this single-center retrospective study. The incidence of individual decompensation events and survival was estimated using competing risk analysis. Risk factors for poor outcomes were identified. RESULTS: The mean age was 47.4 (13.2) years, with most patients (86.5%) being males. Alcohol-related liver disease (42.3%) and viral cirrhosis (22.4%) were the main etiologies with a median Model for End-Stage Liver Disease score of 14 (11-15) at baseline. Over a median follow-up of 42 (24-62) months, 292 patients experienced further decompensations: ascites (n = 283; 96.9%), rebleeding (n = 157; 53.8%), and hepatic encephalopathy (n = 71; 24.3%). Most events occurred with similar frequency across different etiologies, except acute-on-chronic liver failure, which was more common in nonviral cirrhosis (Gray test, P = 0.042). Patients with viral and nonviral cirrhosis had similar survival (5-year survival: 91% and 80.1%, respectively; P = 0.062). Patients with early further decompensations (onset <6 weeks of index AVB event) (n = 40) had a higher mortality (52.5% vs 20.2% for late decompensations; P < 0.001). Active alcohol consumption (hazard ratio [HR]: 9 [5.31-15.3], P < 0.001), high white blood cell count at presentation (HR: 2.5 [1.4-4.4], P = 0.001), and early decompensation (HR: 6.2 [3.6-10.6], P < 0.001) predicted poor survival. DISCUSSION: Despite a high incidence of further decompensation, 5-year survival of patients at this stage of cirrhosis is more than 80% across all etiologies in the absence of early further decompensation and active alcohol consumption.

RESUMEN

Progressive multifocal leukoencephalopathy (PML) is a rare demyelinating central nervous system illness encountered in the setting of immunosuppressive conditions like human immunodeficiency virus / acquired immunodeficiency syndrome, autoimmune diseases and hematologic malignancies. We had a 54-year-old woman with systemic lupus erythematosus and coexisting autoimmune hepatitis who presented with progressive cognitive decline, right hemiparesis and ataxia who was found to have PML. She had severe CD4 lymphopenia. She was managed with low-dose prednisolone and plasma exchange after which she showed significant clinical improvement. This case highlights the diagnostic and therapeutic challenges encountered in managing a case of PML in the setting of autoimmune conditions with profound lymphopenia.

RESUMEN

Background and aims: The pathophysiology of sarcopenia in cirrhosis is poorly understood. We aimed to evaluate the histological alterations in the muscle tissue of patients with cirrhosis and sarcopenia, and identify the regulators of muscle homeostasis. Methods: Computed tomography images at third lumbar vertebral level were used to assess skeletal muscle index (SMI) in 180 patients. Sarcopenia was diagnosed based on the SMI cut-offs from a population of similar ethnicity. Muscle biopsy was obtained from the vastus lateralis in 10 sarcopenic patients with cirrhosis, and the external oblique in five controls (voluntary kidney donors during nephrectomy). Histological changes were assessed by hematoxylin and eosin staining and immunohistochemistry for phospho-FOXO3, phospho-AKT, phospho-mTOR, and apoptosis markers (annexin V and caspase 3). The messenger ribonucleic acid (mRNA) expressions for MSTN, FoxO3, markers of ubiquitin-proteasome pathway (FBXO32, TRIM63), and markers of autophagy (Beclin-1 and LC3) were also quantified. Results: The prevalence of sarcopenia was 14.4%. Muscle histology in sarcopenics showed atrophic angulated fibers (P = 0.002) compared to controls. Immunohistochemistry showed a significant loss of expression of phospho-mTOR (P = 0.026) and an unaltered phospho-AKT (P = 0.089) in sarcopenic patients. There were no differences in the immunostaining for annexin-V, caspase-3, and phospho-FoxO3 between the two groups. The mRNA expressions of MSTN and Beclin-1 were higher in sarcopenics (P = 0.04 and P = 0.04, respectively). The two groups did not differ in the mRNA levels for TRIM63, FBXO32, and LC3. Conclusions: Significant muscle atrophy, increase in autophagy, MSTN gene expression, and an impaired mTOR signaling were seen in patients with sarcopenia and cirrhosis.

RESUMEN

BACKGROUND: The role of branched-chain amino acids (BCAA) in improving muscle mass in cirrhosis is presently debatable. AIMS: To evaluate the role of BCAA in improving muscle mass in a double-blind randomized placebo-controlled trial in patients with cirrhosis having sarcopenia. METHODS: Consecutive patients with cirrhosis with Child-Pugh score < 10 and sarcopenia were randomized to receive either 12 g/day of BCAA orally or a placebo (1:1) for 6 months in addition to a home-based exercise program (30 min/day), dietary counselling and standard medical therapy. Sarcopenia was defined according to gender-specific axial skeletal muscle index (SMI) cut-offs. The primary endpoint was a change in muscle mass based on CT scan (SMI) after 6 months of supplementation. RESULTS: Sixty patients [mean age 41.6 ± 9.9 years; males (66.6%) of predominantly viral (40%) and alcohol-related (31.7%) cirrhosis] were randomized. Baseline clinical and demographic characters were similar except MELD score (10.2 ± 2.8 vs. 12.2 ± 3.5, p = 0.02) and calorie intake (1838.1 kcal ± 631.5 vs. 2217.5 kcal ± 707.3, p = 0.03), both being higher in the placebo arm. After adjusting for both baseline confounders, baseline SMI and protein intake, the change in SMI at 6 months was similar in both groups [mean adjusted difference (MAD) + 0.84, CI - 2.9; + 1.2, p = 0.42] by intention-to-treat analysis. The secondary outcomes including change in handgrip strength (p = 0.65), 6-m gait speed (p = 0.20), 6-min walk distance (p = 0.39) were similar in both arms. Four patients had minor adverse events in each arm. CONCLUSION: Addition of BCAA to exercise, dietary counselling and standard medical therapy did not improve muscle mass in patients with cirrhosis having sarcopenia. (CTRI/2019/05/019269). TRIAL REGISTRATION NUMBER: CTRI/2019/05/019269 (Clinical Trials Registry of India).

RESUMEN

BACKGROUND/AIMS: Multiple definitions of sarcopenia exist and the acceptable criterion that best predicts outcome is lacking. We estimated the prevalence of sarcopenia based on four criteria and assessed their utility in predicting mortality in cirrhotics. METHODS: In a prospective observational study, consecutive Asian patients with cirrhosis underwent testing for handgrip strength (HGS) and estimation of skeletal muscle index (SMI) using computed tomography at the third lumbar vertebra. Sarcopenia was defined based on the Western cut-off (WC; SMI < 50 cm2/m2 for men and <39 cm2/m2 for women), Asian cut-off (AC; SMI < 36.5 cm2/m2 for men and 30.2 cm2/m2 for women), European Working Group on Sarcopenia in Older People-2nd meeting (EWGSOP2) definition incorporating low HGS (<27 kg for men and <16 kg for women) with low SMI (defined by the WC), and EWGSOP2 definition with low HGS and low SMI (defined by AC). Risk factors for mortality were assessed using multivariate Cox-proportional hazards. RESULTS: We included 219 patients with cirrhosis (168 men; mean age 42.6 years) with 50.2% patients having decompensation. Alcohol was the commonest aetiology (33.3%). The prevalence of sarcopenia was highest with the WC (men: 82.1%; women: 62.7%). There was a weak concordance among all criteria (Fleiss' kappa 0.23, 95% confidence interval [CI] 0.10-0.37). Overall, 12-month survival was 86.1% (81.1-91.3%) over a median (interquartile range) follow-up of 12 (6-15) months. Ascites (hazards ratio [HR] 6.27 [95% CI 1.6-24.1]; P < 0.007) and SMI (HR 0.92 [0.85-0.98]; P = 0.021) were independent predictors of mortality. The 12-month mortality rate was higher in patients with sarcopenia, irrespective of criteria (log rank P < 0.05). Low HGS and low SMI (defined by AC) was the best for predicting mortality (HR 3.04 [1.43-6.43]; P = 0.004). CONCLUSION: A weak concordance exists amongst various diagnostic definitions of sarcopenia. Sarcopenia diagnosed by a combination of low HGS and population-specific SMI cut-off (AC) best predicts mortality.

RESUMEN

AIMS: Lockdown and restricted mobility due to the pandemic of corona virus disease  2019 (COVID-19) has severely affected the continuity of healthcare of patients with acute and chronic diseases. We evaluated the impact of COVID-19 on the adherence to gluten-free diet (GFD), symptom control, and quality of life (QOL) in patients with celiac disease (CeD). METHODS: A questionnaire, consisting of both ad-hoc and validated questions, was created after review of literature, group discussions, and expert meetings. Standardized questionnaires namely CeD adherence test (CDAT), celiac symptom index score, and CeD-related QOL were used. The web-based questionnaire was sent to 3130 patients via social media and 452 responses (14.4%) were received. Also, additional 68 patients (not available on any social media application) were interviewed telephonically by a trained dietitian. RESULTS: Overall, 505 patients (females: 318; mean age: 24.1±14.2 years) were included. While only 6.7% (n = 34) had poor compliance to GFD (CDAT > 17) before COVID-19 pandemic, it almost doubled to 12.6% (n = 64) during the COVID-19 pandemic times (p = 0.02). Furthermore, 4.9% (n = 25) of patients were diagnosed contacting  COVID-19. Interestingly, 73.2% (n = 370) patients preferred online appointment than physical appointment. Most common difficulties faced during lockdown period were high delivery charges for getting gluten-free (GF) food at home (54.4%), increased prices of regular GF food (43.1%), and travelling long distance to arrange GF food (44.9%). CONCLUSIONS: The COVID-19 pandemic has substantially affected the adherence, symptom control, and QOL in patients with CeD, attributable to unavailability, shortage of money, and heightened cost of GF food. The pandemic has offered an opportunity to practice teleconsultation approach for patients with CeD.

RESUMEN

BACKGROUND AND AIMS: Hemodynamic response to pharmacotherapy improves survival in patients with cirrhosis post variceal bleeding, but long-term outcomes remain unexplored especially in this part of the world. We aimed to study the long-term impact of portal pressure reduction on liver-related outcomes after index variceal bleed. METHODS: Patients with hepatic venous pressure gradient (HVPG) more than 12 mm Hg after index variceal bleed were given non-selective beta-blockers in combination with variceal band ligation. HVPG response was assessed after 4 weeks. Patients were followed up for rebleed events, survival, additional decompensation events and safety outcomes. Rebleed and other decompensations were compared using competing risks analysis, taking death as competing event, and survival was compared using Kaplan-Meier analysis. RESULTS: Forty-eight patients (29 responders and 19 non-responders) were followed up for a median duration of 45 (24-56) months. Rebleeding rates at 1, 3 and 5 years were 10.3%, 20.7% and 20.7% in responders and 15.8%, 44.7% and 51.1% in non-responders, respectively (Gray's test, P = 0.044). Survival rates at 1, 3 and 5 years were 89.7%, 72.1% and 51.9% in responders and 89.5%, 44% and 37.7% in non-responders, respectively (log-rank test, P = 0.1). Both severity of liver disease (MELD score, multivariate sub-distributional hazards ratio: 1.166 [1.014-1.341], P = 0.030) and HVPG non-response (multivariate sub-distributional hazards ratio: 2.476 [1.87-7.030], P = 0.045) predicted rebleeding risk while survival was dependent only on severity of liver disease (MELD > 12, multivariate hazards ratio: 2.36 [1.04-5.38], P = 0.041). CONCLUSION: Baseline severity of liver disease predicted survival and rebleed in these patients. Hemodynamic response, although associated with lower rebleeding rate, had limited impact on survival.

RESUMEN

BACKGROUND AND AIM: Risk stratification beyond the endoscopic classification of esophageal varices (EVs) to predict first episode of variceal bleeding (VB) is currently limited in patients with compensated advanced chronic liver disease (cACLD). We aimed to assess if machine learning (ML) could be used for predicting future VB more accurately. METHODS: In this retrospective analysis, data from patients of cACLD with EVs, laboratory parameters and liver stiffness measurement (LSM) were used to generate an extreme-gradient boosting (XGBoost) algorithm to predict the risk of VB. The performance characteristics of ML and endoscopic classification were compared in internal and external validation cohorts. Bleeding rates were estimated in subgroups identified upon risk stratification with combination of model and endoscopic classification. RESULTS: Eight hundred twenty-eight patients of cACLD with EVs, predominantly related to non-alcoholic fatty liver disease (28.6%), alcohol (23.7%) and hepatitis B (23.1%) were included, with 455 (55%) having the high-risk varices. Over a median follow-up of 24 (12-43) months, 163 patients developed VB. The accuracy of machine learning (ML) based model to predict future VB was 98.7 (97.4-99.5)%, 93.7 (88.8-97.2)%, and 85.7 (82.1-90.5)% in derivation (n = 497), internal validation (n = 149), and external validation (n = 182) cohorts, respectively, which was better than endoscopic classification [58.9 (55.5-62.3)%] alone. Patients stratified high risk on both endoscopy and model had 1-year and 3-year bleeding rates of 31-43% and 64-85%, respectively, whereas those stratified as low risk on both had 1-year and 3-year bleeding rates of 0-1.6% and 0-3.4%, respectively. Endoscopic classification and LSM were the major determinants of model's performance. CONCLUSION: Application of ML model improved the performance of endoscopic stratification to predict VB in patients with cACLD with EVs.

RESUMEN

Celiac disease (CeD) is a systemic, immune-mediated enteropathy, which is triggered by gluten protein in genetically susceptible individuals. CeD, once thought to be an uncommon disease, is now recognized to affect approximately 40-60 million people globally. While CeD is now well reported from a few Asian countries such as India, China, Pakistan, and Middle Eastern countries; it is still believed to be uncommon in the rest of Asia. Gluten-related diseases other than CeD, like non-celiac gluten sensitivity (NCGS) are also emerging globally. CeD and NCGS may present with either intestinal or extra-intestinal symptoms, and a proportion of them have overlapping symptoms with irritable bowel syndrome. Hence, many of them are misdiagnosed as having irritable bowel syndrome in clinical practice. In this review, we discuss the emergence of CeD and other gluten-related disorders, both globally and in Asia, the overlapping manifestations between gluten-related disorders and irritable bowel syndrome, and the challenges associated with diagnosis and management of CeD in Asia.

RESUMEN

AIMS AND BACKGROUND: There is limited information on comparison of clinical outcomes with carvedilol for secondary prophylaxis following acute variceal bleed (AVB) when compared with propranolol. We report long-term clinical and safety outcomes of a randomised controlled trial comparing carvedilol with propranolol with respect to reduction in hepatic venous pressure gradient (HVPG) in patients after AVB. METHODS: We conducted a post-hoc analysis of patients recruited in an open-label randomized controlled trial comparing carvedilol and propranolol following AVB, and estimated long-term rates of rebleed, survival, additional decompensation events and safety outcomes. Rebleed and other decompensations were compared using competing risks analysis, taking death as competing event, and survival was compared using Kaplan-Meier analysis. RESULTS: Forty-eight patients (25 taking carvedilol; 23 propranolol) were followed up for 6 years from randomization. More number of patients on carvedilol had HVPG response when compared with those taking propranolol (72%- carvedilol versus 47.8% propranolol, p = 0.047). Comparable 1-year and 3-year rates of rebleed (16.0% and 24.0% for carvedilol versus 8.9% and 36.7% for propranolol; p = 0.457) and survival (94.7% and 89.0% for carvedilol versus 100.0% and 79.8% for propranolol; p = 0.76) were obtained. New/worsening ascites was more common in those receiving propranolol (69.5% vs 40%; p = 0.04). Other clinical decompensations and complications of liver disease occurred at comparable rates between two groups. Drug-related adverse-events were similar in both groups. CONCLUSION: Despite higher degree of HVPG response, long-term clinical, survival and safety outcomes in carvedilol are similar to those of propranolol in patients with decompensated cirrhosis after index variceal bleed with the exception of ascites that developed less frequently in patients with carvedilol.

RESUMEN

Chronic pancreatitis (CP) is an irreversible disease with increased oxidative stress. The therapeutic role of antioxidants for pain reduction in CP is debatable. A systematic review of articles in PubMed and Embase until February 2020 was performed. Only randomized controlled trials conducted on humans to evaluate the therapeutic effects of antioxidants for pain in CP were included. Studies of other design, nonhuman studies, and those that did not objectively assess pain were excluded. Twelve articles and four articles were eligible for qualitative and quantitative analysis, respectively. The four included studies had a total of 352 participants. Pain reduction as measured by a visual analog scale was not significantly different in the antioxidant group compared to placebo (standardized mean difference = -0.14 [95% confidence interval [CI] = -0.44 to 0.17]; P = 0.38). Number of pain-free participants was also similar (odds ratio [OR] = 1.59 [0.97-2.59]; P = 0.06). There was no difference in outcome when comparing different etiologies of CP or age group. The reduction in the number of analgesics used did not differ between both groups. Antioxidants were not associated with increased adverse events (OR = 2.59 [CI = 0.77-8.69]; P = 0.12). A qualitative analysis on the effect on quality of life did not suggest any significant improvement with antioxidants. There was no significant pain reduction or change in quality of life in CP patients with use of antioxidants. This makes their routine use in the management of CP questionable. However, further studies may identify a subgroup where they are more useful.

RESUMEN

BACKGROUND AND AIMS: Autoimmune hepatitis presenting as acute on chronic liver failure (AIH-ACLF) is a novel entity with limited data on clinical course and management. We assessed outcomes in patients of AIH-ACLF with no extrahepatic organ dysfunction/failure when administered steroids. METHODS: In this retrospective analysis, clinical data, laboratory parameters, liver biopsy indices and prognostic scores such as model for end-stage liver disease (MELD) and Child-Turcotte-Pugh (CTP) scores at baseline were computed for patients with AIH-ACLF and compared across strata of incident infections and transplant-free survival. The primary outcome was 90-day transplant-free survival. Biochemical remission was assessed, and predictors of end points were identified. RESULTS: Twenty-nine patients of AIH-ACLF were included with a median follow-up of 4 months. The 90- and 180-day transplant-free survival rates of 55.2 [95% confidence interval (CI): 39.7-76.6]% and 30.2(95% CI: 16.7-54.6)%, respectively, were attained on steroids. Three patients (10.3%) underwent liver transplant while 16 (55.2%) deaths occurred. Infections developed in 12 patients (41.3%), leading to worsening prognostic scores, new onset organ dysfunction/failure and 11 deaths. Seven of ten patients (70%) in the transplant-free survivor group attained biochemical remission on follow-up. The MELD score<24 (sensitivity: 68.4%; specificity: 80%) and CTP<11 (sensitivity: 78.9%; specificity: 90%) had best predictive value for survival, in addition to decrease in the MELD score at 2 weeks (sensitivity: 78.9%; specificity: 70%). CONCLUSION: Patients with AIH-ACLF have a morbid disease course despite treatment with steroids. Patients with no extrahepatic organ failure with good baseline prognostic scores may be administered steroids with close monitoring for change in MELD over 2 weeks.

RESUMEN

BACKGROUND/OBJECTIVE: There is a paucity of data on the management of gastrointestinal (GI) bleeding in patients with Coronavirus disease -2019 (COVID-19) amid concerns about the risk of transmission during endoscopic procedures. We aimed to study the outcomes of conservative treatment for GI bleeding in patients with COVID-19. METHODS: In this retrospective analysis, 24 of 1342 (1.8%) patients with COVID-19, presenting with GI bleeding from 22nd April to 22nd July 2020, were included. RESULTS: The mean age of patients was 45.8 ± 12.7 years; 17 (70.8%) were males; upper GI (UGI) bleeding: lower GI (LGI) 23:1. Twenty-two (91.6%) patients had evidence of cirrhosis- 21 presented with UGI bleeding while one had bleeding from hemorrhoids. Two patients without cirrhosis were presumed to have non-variceal bleeding. The medical therapy for UGI bleeding included vasoconstrictors-somatostatin in 17 (73.9%) and terlipressin in 4 (17.4%) patients. All patients with UGI bleeding received proton pump inhibitors and antibiotics. Packed red blood cells (PRBCs), fresh frozen plasma (FFPs) and platelets were transfused in 14 (60.9%), 3 (13.0%) and 3 (13.0%), respectively. The median PRBCs transfused was 1 (0-3) unit(s). The initial control of UGI bleeding was achieved in all 23 patients and none required an emergency endoscopy. At 5-day follow-up, none rebled or died. Two patients later rebled, one had intermittent bleed due to gastric antral vascular ectasia, while another had rebleed 19 days after discharge. Three (12.5%) cirrhosis patients succumbed to acute hypoxemic respiratory failure during hospital stay. CONCLUSION: Conservative management strategies including pharmacotherapy, restrictive transfusion strategy, and close hemodynamic monitoring can successfully manage GI bleeding in COVID-19 patients and reduce need for urgent endoscopy. The decision for proceeding with endoscopy should be taken by a multidisciplinary team after consideration of the patient's condition, response to treatment, resources and the risks involved, on a case to case basis.
