RESUMEN

INTRODUCTION: Limited evidence exists on the optimal strategy to correct iron deficiency anemia after variceal bleeding (VB) in cirrhosis. This trial compared the efficacy and safety of intravenous ferric carboxymaltose (IV-FCM) with those of oral iron therapy in this cohort. METHODS: In this open-label, single-center, randomized controlled trial, eligible patients with hemoglobin <10 g/dL and iron deficiency (ferritin <100 ng/mL) after VB received either IV-FCM (1,500-2,000 mg) divided into 2 doses (n = 48) or oral carbonyl iron (100 mg elemental iron/day) (n = 44) for 3 months. The primary outcome was change in hemoglobin at 3 months. Secondary outcomes included improvement in anemia (last hemoglobin >12 g/dL), normalization of iron stores (ferritin >100 ng/mL), liver-related adverse events, adverse drug reactions, and changes in quality of life (CLDQOL questionnaire). RESULTS: Baseline characteristics, including median Child-Turcotte-Pugh score 7 (interquartile range [IQR] 6-9), Model for End-Stage Liver Disease score 12 (IQR 10-17), blood hemoglobin (8.25 ± 1.06 g/dL), and ferritin (30.00 ng/mL [15.00-66.50]), were comparable in both arms. The median increase in hemoglobin at 3 months in the IV and oral arms was 3.65 g/dL (IQR 2.55-5.25) and 1.10 g/dL (IQR 0.05-2.90 g/dL) ( P < 0.001), respectively. Iron stores normalized in 84.6% and 21% of the IV and oral arms, respectively ( P < 0.001). Anemia improved in 50% and 21.9% in the IV and oral arms, respectively ( P < 0.009). Patients in the IV arm showed a significant improvement in all domains of CLDQOL. Liver-related adverse events were comparable in both arms. Transient mild/moderate hypophosphatemia developed in 43% of patients receiving IV-FCM. DISCUSSION: Intravenous iron replacement is efficacious and safe to treat iron deficiency anemia after VB in patients with cirrhosis.

RESUMEN

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) is a deadly disease due to the lack of early detection. Because chronic pancreatitis (CP) patients are a high-risk group for pancreatic cancer, this study aimed to assess the differential miRNA profile in pancreatic tissue of patients with CP and pancreatic cancer. METHODS: MiRNAs were isolated from formalin-fixed paraffin-embedded pancreatic tissue of 22 PDAC patients, 18 CP patients, and 10 normal pancreatic tissues from autopsy (C) cases and processed for next-generation sequencing. Known and novel miRNAs were identified and analyzed for differential miRNA expression, target prediction, and pathway enrichment between groups. RESULTS: Among the miRNAs identified, 166 known and 17 novel miRNAs were found exclusively in PDAC tissues, while 106 known and 10 novel miRNAs were found specifically in CP tissues. The pathways targeted by PDAC-specific miRNAs and differentially expressed miRNAs between PDAC versus CP tissues and PDAC versus control tissues were the proteoglycans pathway, Hippo signaling pathway, adherens junction, and transforming growth factor-ß signaling pathway. CONCLUSIONS: This study resulted in a set of exclusive and differentially expressed miRNAs in PDAC and CP can be assessed for their diagnostic value. In addition, studying the role of miRNA-target gene interactions in carcinogenesis may open new therapeutic avenues.

RESUMEN

INTRODUCTION: Nutrition plays an important role in management of acute pancreatitis (AP) and decreases its severity and infectious complications. Various formulations of enteral nutrition (EN) are available and are costly. For developing countries, cost and availability is a major issue and kitchen-based diet should be explored in patients with AP. AIM: Comparison of kitchen-based diet with a commercially available polymeric formulation in terms of various outcomes in patients with AP within 14 days after the onset of pain. METHODS: Sixty patients (39 male, mean age 36.1 ± 12.7 years) of moderately severe and severe AP of any etiology were randomized (30 in each group) to either kitchen-based diet or commercial polymeric formulation group. Outcome measures were refeeding pain, tolerability, infectious complications, mortality, total hospital/intensive care unit stay; and change in serum C-reactive protein (CRP), transferrin and pre albumin. RESULTS: There was no significant difference in baseline demographic and biochemical parameters in both groups. No difference was observed in refeeding pain (7.1% vs 8%, p = 0.99), tolerability (28.6% vs 12%, p = 0.17), infectious complications (57.14% vs 36%, p = 0.12), mortality (31.7% vs 20%, p = 0.69), hospital stay (19.5 vs 23.5 days, p = 0.86), CRP (74.4 vs 59 mg/L, p = 0.97), transferrin levels (23.6 vs 25.6 mg/dL, p = 0.75) and pre albumin (9.45 vs 13.09 mg/dL, p = 0.68) in both groups. CONCLUSION: Kitchen-based diet is comparable to commercial polymeric formulation for the early initiation of enteral nutrition in patients with severe or moderately severe acute pancreatitis. CLINICAL TRIAL REGISTRATION: Trial registered with the Clinical Trials registry-India (CTRI/2018/01/011188).

RESUMEN

AIM: Periampullary adenocarcinoma (PAC) is a malignant tumor originating at the ampulla of Vater, distal common bile duct, head of the pancreas, ampulla and duodenum. The levels of circulating Th17 cells and Th17-related cytokines in patients with PAC remain unreported. Therefore, the aim of this study was to determine the levels of circulating Th17 cells and Th17-related cytokines in patients with PAC. MATERIALS AND METHODS: Flow cytometry was used to measure Th17 cell proportions in PBMCs from 60 PAC patients and 30 healthy controls. Enzyme-linked immunosorbent assay (ELISA) was used to quantify IL-17A and IL-23 levels in serum samples, while quantitative reverse transcription polymerase chain reaction (qRT-PCR) assessed IL-17A mRNA expression and Th17-related transcription factors (RORγt and STAT3) in tissue samples. RESULTS: The findings showed a substantial increase in Th17 cell percentages, elevated concentrations of IL-17A and IL-23, and higher mRNA expression levels of IL-17A, RORγt, and STAT3 in patients with PAC when compared to healthy controls (HCs). CONCLUSION: Th17 cells play an important role in the pathogenesis of PAC and may represent potential therapeutic targets.

RESUMEN

BACKGROUND: In cirrhosis patients with acute variceal bleeding (AVB), the optimal duration of vasoconstrictor therapy after endoscopic haemostasis is unclear. AIMS: We aimed to compare efficacy of 1-day versus 3-day terlipressin therapy in cirrhosis patients with AVB post-endoscopic intervention. The primary objective was to compare rebleeding at 5 days between the two arms. Secondary objectives included rebleeding and mortality rates at 6 weeks. METHODS: In this open-label, randomised controlled trial, cirrhosis patients with AVB were randomised to either 1-day or 3-day terlipressin therapy. RESULTS: A total of 150 cirrhosis patients with AVB were recruited to receive either 1 day (n = 75) or 3 days (n = 75) of terlipressin therapy. One patient from 1-day arm was excluded. Modified intention-to-treat analysis included 149 patients. Baseline characteristics were comparable between the two groups. Rebleeding at 5 days: 3 (4.1%; 95% confidence interval [CI]: 0.4-9.0) versus 4 (5.3%; 95% CI: 2.0-10.0), risk difference (RD) p = 0.726 and 5-day mortality rates: 1 (1.4%; 95% CI: 0-7.3) versus 1 (1.3%; 95% CI: 0.2-7.0), RD p = 0.960 were similar. Rebleeding at 42 days: 9 (12.2%; 95% CI: 7.0-20.0) versus 10 (13.3%; 95% CI: 7.0-20.0), RD p = 0.842 and mortality at 42 days: 5 (6.8%; 95% CI: 3.0-10.0) versus 4 (5.3%; 95% CI: 2.0-10.0), RD p = 0.704 were also similar. Patients in the 1-day terlipressin therapy arm experienced significantly fewer adverse effects compared with those receiving 3 days of terlipressin therapy: 28 (37.8%) versus 42 (56%), p = 0.026. CONCLUSIONS: Our results suggest that 1 day of terlipressin therapy is associated with similar 5-day and 42-day rebleeding rates, 42-day mortality and an overall superior safety profile compared with 3-day of terlipressin therapy. These findings require to be validated in double-blinded, larger, multiethnic and multicentre studies across the various stages of cirrhosis (CTRI/2019/10/021771).

RESUMEN

BACKGROUND: Laparoscopic Heller's myotomy (LHM) is an established treatment for achalasia cardia. Anti-reflux procedures (ARP) are recommended with LHM to reduce the post-operative reflux though the optimal anti-reflux procedure is still debatable. This study reports on the long-term outcomes of LHM with Angle-of-His accentuation (AOH) in patients of achalasia cardia. METHODS: One hundred thirty-six patients of achalasia cardia undergoing LHM with AOH between January 2010 to October 2021 with a minimum follow-up of one year were evaluated for symptomatic outcomes using Eckardt score (ES), DeMeester heartburn (DMH) score and achalasia disease specific quality of life (A-DsQoL) questionnaire. Upper gastrointestinal endoscopy, high resolution manometry (HRM) and timed barium esophagogram (TBE) were performed when feasible and rates of esophagitis and improvement in HRM and TBE parameters evaluated. Time dependent rates of success were calculated with respect to improvement in ES and dysphagia-, regurgitation- and heartburn-free survival using Kaplan-Meier analysis. RESULTS: At a median follow-up of 65.5 months, the overall success (ES ≤ 3) was 94.1%. There was statistically significant improvement in ES, heartburn score and A-DsQoL score (p < 0.00001, p = 0.002 and p < 0.00001). Significant heartburn (score ≥ 2) was seen in 12.5% subjects with 9.5% patients reporting frequent PPI use (> 3 days per week). LA-B and above esophagitis was seen in 12.7%. HRM and TBE parameters also showed a significant improvement as compared to pre-operative values (IRP: p < 0.0001, column height: p < 0.0001, column width: p = 0.0002). Kaplan-Meier analysis showed dysphagia, regurgitation, and heartburn free survival of 75%, 96.2% and 72.3% respectively at 10 years. CONCLUSIONS: LHM with AOH gives a lasting relief of symptoms in patients of achalasia cardia with heartburn rates similar to that reported in studies using Dor's or Toupet's fundoplication with LHM. Hence, LHM with AOH may be a preferred choice in patients of achalasia cardia given the simplicity of the procedure.

RESUMEN

BACKGROUND AND AIMS: Lumbar vertebral bone attenuation, measured in Hounsfield units (HU) can indirectly indicate the bone mineral density (BMD). The aim of this study is to determine the optimal HU threshold on abdominal computed tomography (CT) scans to detect osteopathy in patients with chronic pancreatitis (CP). METHODS: This cross-sectional study included patients with CP who underwent CT scans to measure HU at L1 to L4 vertebrae. The mean lumbar vertebral attenuation of female renal transplant donors, aged 20-30 years was utilized to calculate the T-scoreHU of all patients at each vertebral level. Receiver operator characteristic analysis was used to determine the HU and T-scoreHU for diagnosis of osteopathy in patients with CP. Dual-energy X-ray absorptiometry value was used to categorize osteopenia and osteoporosis. RESULTS: A total of 175 patients (mean age, 34.5 ± 10.9 years; 72 % males) and 33 female renal transplant donors (mean age, 28 ± 2.4 years) were included. A threshold HU value 212 or T scoreHU of -1.80 at L1 vertebra was found to have a 78 % sensitivity and 70 % specificity for differentiating between osteoporosis and non-osteoporosis (osteopenia and normal BMD). Similarly, a threshold HU value of 254 or a T-scoreHU of -0.46 at L1 vertebra had 78 % sensitivity and 71 % specificity for distinguishing between normal and low BMD (osteoporosis and osteopenia). CONCLUSION: Abdominal CT images, which are routinely performed in chronic pancreatitis, can be used for opportunistic screening of osteoporosis and osteopenia without additional cost or radiation exposure.

RESUMEN

BACKGROUND AND AIMS: Inflammatory head mass of pancreas (IMP) developing in background of chronic pancreatitis (CP) is difficult to distinguish from carcinoma pancreas. We aimed to delineate natural course of IMP and predict their malignancy risk, avoiding unnecessary biopsies. MATERIALS AND METHODS: In this retrospective single-center study, clinical records of patients with CP with diagnosed pancreatic head mass were reviewed. Clinical, laboratory, imaging, endoscopic findings, and follow-up details were retrieved from prospectively maintained database. A diagnostic nomogram was developed combining serum cancer antigen 19-9 and endoscopic ultrasound (EUS) findings to predict the risk of malignancy. RESULTS: We identified 107 patients with pancreatic head mass with CP of whom 87 (81.3%) were IMP and 20 (18.7%) were malignant. Patients with IMP were more frequently young males with alcohol-related CP and low CA 19-9 in comparison with those with malignancy (age IMP: 41.3 ± 11.3 vs carcinoma: 49.3 ± 14.5 years [ P = 0.009]; males 89.7% vs 65% [ P = 0.011]; alcoholic etiology: 71.3% vs 20% [ P < 0.001]; median CA 19-9: 25.78 [interquartile range, 7.20-120.60] vs 1034.50 [106.65-7808.25] [ P < 0.001]). A diagnostic nomogram combining CA 19-9 and EUS findings could identify malignancy with an optimism-corrected c-statistic of 0.905, which was better than both CA 19-9 (0.80) and EUS alone (0.826). Patients with IMP had relatively benign disease course with 40.2% biliary obstruction, 20.7% portal venous thrombosis, 14.9% gastric outlet obstruction, and 1-, 3-, and 5-year survival being 97.3%, 92.7%, and 92.0%, respectively. Surgery was required in only 12 patients (13.8%) with IMP. CONCLUSIONS: Combination of CA 19-9 and EUS best identifies malignancy risk in patients with IMP, who have otherwise benign course.

RESUMEN

Background and aims: Limited data exist on the safety of early nasogastric (NG) feeding in patients with cirrhosis after endotherapy for variceal bleeding (VB). We studied the impact of early NG tube feeding in these patients in this proof-of-concept open-label randomized controlled trial. Methods: Eligible patients with cirrhosis undergoing endotherapy for VB were randomized to receive either a liquid diet through a 14 Fr NG tube (commencing 1 h after endotherapy) (early feeding [EF] group) or sips of water and lemon water orally (standard-of-care [SOC] group) for total duration of 48 h. The primary outcome was 5-day rebleeding in both arms. Other outcomes included 5-day infection rate, hepatic encephalopathy during hospitalization, and 6-week mortality. Results: Eighty patients (Mean age: 41 ± 11.5 years; males [82.5%]; alcohol etiology [55%]) were included. Baseline median Child-Pugh and MELD scores were similar (CTP: 8 [IQR: 8-9] vs 9 [8-9.25]; P = 0.47 and MELDNa: 13 [10.75-16.25] vs 15 [12-18.25]; P = 0.16). The 5-day rebleeding rates in EF and SOC groups were 2.5% and 5%, respectively (P = 0.55), and non-inferiority or superiority of either could not be demonstrated. The incidence of infection (2.5% [EF] vs 2.5% [SOC]; P = 1.00) and development of HE (5% [EF] vs 2.5% [SOC]; P = 0.36) during hospitalization were comparable. The average daily calorie and protein intake in the EF group during the 48 h was 1318 ± 240 Kcals and 43.4 ± 9.2 g of proteins. No patient in the EF group had feed intolerance. Conclusion: Early initiation of NG tube-based feeding after endotherapy in VB appears safe and well tolerated without the additional risk of rebleeding or encephalopathy.

RESUMEN

Background & objectives: Vitamin D plays an important role in bone metabolism, and liver is the intermediary site of vitamin D metabolism. The purpose of this study was to study the prevalence of vitamin D deficiency and bone health in patients with cirrhosis. Methods: Prospectively, serum 25-hydroxy vitamin D [25(OH)D] level were assessed in cirrhotics by chemiluminescence method. Endocrine Society Clinical practice guideline was used to define deficiency and insufficiency of vitamin D. Bone mineral density (BMD) was assessed using dual-energy X-ray absorptiometry and the World Health Organization criteria was used to define osteoporosis and osteopenia. The lowest T score at the left hip neck or lumbar spine was taken as osteoporosis or osteopenia. The Child-Turcotte-Pugh score was used to assess the severity of cirrhosis. Results: Cirrhotics (n=350, male: 278, compensated: 210) were included. Mean serum 25(OH)D level was 8.75 ng/ml. The prevalence of vitamin D deficiency (VDD) and low-BMD (osteopenia and osteoporosis) was 89.4 and 86 per cent, respectively. VDD, insufficiency and osteoporosis was found in 86.7, 11.9 and 33.8 per cent, respectively, in patients with compensated cirrhosis; and 93.6, 3.6 and 40 per cent, respectively, in patients with decompensated cirrhosis. Body mass index of >25 kg/m2 was protective for bone health. Interpretation & conclusions: VDD and low-BMD is prevalent in Indian patients with cirrhosis and should be looked for in patients with cirrhosis for its prevention.

RESUMEN

Chronic pancreatitis is a chronic fibro-inflammatory disorder of the pancreas, resulting in recurrent abdominal pain, diabetes mellitus, and malnutrition. It may lead to various other complications such as pseudocyst formation, benign biliary stricture, gastric outlet obstruction; and vascular complications like venous thrombosis, variceal and pseudoaneurysmal bleed. Development of varices is usually due to chronic venous thrombosis with collateral formation and variceal bleeding can easily be tackled by endoscopic therapy. Pseudoaneurysmal bleed can be catastrophic and requires radiological interventions including digital subtraction angiography followed by endovascular obliteration, or sometimes with a percutaneous or an endoscopic ultrasound-guided approach in technically difficult situations. Procedure-related bleed is usually venous and mostly managed conservatively. Procedure-related arterial bleed, however, may require radiological interventions.

RESUMEN

T-helper 17 (Th17) cells are a subset of CD4+ helper T cells that produce interleukin 17 (IL-17) and play a crucial role in the pathogenesis of inflammatory and autoimmune diseases. Few studies have been conducted to determine the role of Th17 cells in the tumorigenesis and development of pancreatic ductal adenocarcinoma (PDAC); however, its role is still unclear. In this study, the percentage of circulating Th17 cells and serum levels of IL-17A and IL-23 were analyzed using flow cytometry and ELISA, respectively, in 40 PDAC patients, 30 chronic pancreatitis (CP) patients and 30 healthy controls (HC). In addition, the mRNA expression levels of IL-17A, STAT3 and RORγt in tissue samples were quantified by qRT-PCR. The results showed that the percentage of circulating Th17 cells and the concentrations of serum IL-17A and IL-23 were significantly increased in PDAC patients as compared to CP and HC (P < 0.001). In addition, the higher level of IL-17A was significantly correlated with the poor overall survival of the PDAC patients. Furthermore, the frequencies of Th17 cells and IL-17A were significantly higher in stage III+IV PDAC patients versus stage I+II. A significant increase in IL-17A, STAT3 and RORγT mRNA was observed in patients with PDAC. Taken together, these findings suggest that the increased circulating Th17 cells and serum IL-17A may be involved in the development and metastasis of PDAC, and thus represent potential targets for the treatment of PDAC.

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

BACKGROUND: Although rectal nonsteroidal anti-inflammatory drugs (NSAIDs) have been shown to be effective for the prevention of post-ERCP (endoscopic retrograde cholangiopancreatography) pancreatitis (PEP) in high-risk patients, the benefit in average-risk patients is unclear. We aimed at assessing the benefit of prophylactic rectal NSAIDs in unselected consecutive patients to prevent PEP. METHODS: All patients undergoing index ERCP procedures from January 2018 until March 2020 were included. All patients received prophylactic rectal diclofenac. A prophylactic pancreatic duct (PD) stent was placed if there was repeated PD cannulation, at the discretion of the endoscopist. The frequency of PEP was compared with historical controls. RESULTS: Of 769 patients who underwent ERCP, 34 (4.4%) developed PEP (mild in 29 [85.3%], moderate in four [11.8%] and severe in one [2.9%]). Female gender, precut sphincterotomy, inadvertent PD cannulation and procedural time of > 30 minutes predicted PEP in univariate analysis. Inadvertent PD cannulation (OR 4.6, 95% CI: 1.8-11.7; p < 0.001) and procedural time of > 30 minutes (OR 8.5, 95% CI: 3.7-10.1; p < 0.001) were independent risk factors on multivariate analysis. When compared with historical controls, the odds of PEP with prophylactic use of rectal NSAIDs and selective PD stenting was 0.54 (CI: 0.31-0.93, p = 0.027). The number needed to treat (NNT) was 22 to prevent one PEP with prophylactic rectal NSAIDs. CONCLUSION: Routine use of prophylactic rectal NSAIDs effectively prevents the occurrence of PEP in unselected consecutive patients in a real-world scenario.

RESUMEN

Acute pancreatitis (AP) has varying severity, and moderately severe and severe AP has prolonged hospitalization and requires multiple interventions. These patients are at risk of malnutrition. There is no proven pharmacotherapy for AP, however, apart from fluid resuscitation, analgesics, and organ support, nutrition plays an important role in the management of AP. Oral or enteral nutrition (EN) is the preferred route of nutrition in AP, however, in a subset of patients, parenteral nutrition is required. EN has various physiological benefits and decreases the risk of infection, intervention, and mortality. There is no proven role of probiotics, glutamine supplementation, antioxidants, and pancreatic enzyme replacement therapy in patients with AP.

RESUMEN

Non-selective beta-blockers (NSBBs) have a role in the management of portal hypertension. They are currently advocated in patients with clinically significant portal hypertension (CSPH) based on Baveno-VII consensus. Current survey aimed to evaluate the practice and perceptions of prescribing NSBBs in portal hypertension by gastroenterologists and hepatologists in Asia-Pacific region in patients with compensated cirrhosis. Out of 1500 gastroenterologists approached in the region, 328 gastroenterologists responded and completed the survey. 75% of the respondents were found not to be following practice of evaluating CSPH as they prescribed NSBBs in patients of compensated cirrhosis with high-risk varices only. Major concerns raised were non-availability of hepatic venous pressure gradient and reliable non-invasive tests as surrogate of CSPH to adapt PREDESCI methodology. While 56.7% used carvedilol as the preferred NSBB to treat patients with compensated cirrhosis, 43.3% used propranolol. This survey assessed the real-world scenario of prescribing NSBBs among practicing gastroenterologists/hepatologists in patients with compensated cirrhosis.
