Background: The clinical features and outcomes of hypertriglyceridemia-induced acute pancreatitis (HTG-AP) are not well-established., Objective: To evaluate the clinical characteristics of HTG-AP in an international, multicenter prospective cohort., Methods: Data collection was conducted prospectively through APPRENTICE between 2015 and 2018. HTG-AP was defined as serum TG levels >500 mg/dl in the absence of other common etiologies of AP. Three multivariate logistic regression models were performed to assess whether HTG-AP is associated with SIRS positive status, ICU admission and/or moderately-severe/severe AP., Results: 1,478 patients were included in the study; 69 subjects (4.7%) were diagnosed with HTG-AP. HTG-AP patients were more likely to be younger (mean 40 vs 50 years; p < 0.001), male (67% vs 52%; p = 0.018), and with a higher BMI (mean 30.4 vs 27.5 kg/m 2 ; p = 0.0002). HTG-AP subjects reported more frequent active alcohol use (71% vs 49%; p < 0.001), and diabetes mellitus (59% vs 15%; p < 0.001). None of the above risk factors/variables was found to be independently associated with SIRS positive status, ICU admission, or severity in the multivariate logistic regression models. These results were similar when including only the 785 subjects with TG levels measured within 48 h from admission., Conclusion: HTG-AP was found to be the 4th most common etiology of AP. HTG-AP patients had distinct baseline characteristics, but their clinical outcomes were similar compared to other etiologies of AP., Competing Interests: Declaration of competing interest The Authors declare that there is no conflict of interest., (Copyright © 2020 IAP and EPC.

Introduction: The primary aim of this study was to evaluate efficacy, safety and short-term pain relief after ESWL for large pancreatic calculi in over 5000 patients at a single center., Methods: This is a retrospective analysis of prospectively collected data. Patients with painful calculi >5 mm, located in the head, neck and body region in the MPD, who were not amenable for extraction by the standard procedure of endoscopic pancreatic sphincterotomy were subjected to ESWL using a third generation dual focus lithotripter. Patients were followed up at 6 months for outcome evaluation., Results: A total of 5124 patients (66% males) were subjected to ESWL. Majority of stones (79.2%) were radiopaque. Single calculi were seen in 3851 (75.1%).The majority of stones were located in head region of MPD in 2824 (55.1%) patients. 4386 (85.5%) patients required 3 or less sessions for fragmentation and complete stone clearance was achieved in 3722 (72.6%). EPS was performed in 5022 (98%) while PD stenting was required in 3536 (69%) patients. Of the 4280 patients followed up for 6 months, 3529 (82.6%) patients were pain free. Another 512 (11.9%) patients had significant reduction in VAS score. In 229 (5.3%) there was no decrease in pain intensity. Minor and self-limiting complications were reported in 1153 (22.5%)., Discussion: Our study confirms the safety and efficacy and short-term pain relief of ESWL for large calculi in the MPD. In properly selected patients, this should be offered as the first line of therapy for all large MPD calculi not amenable to the standard techniques of stone extraction., (Copyright © 2019 IAP and EPC.

Background: In severe acute pancreatitis (AP), intravenous glutamine has been shown to reduce the rate of complications, hospital stay, and mortality. In the present randomized trial, we aimed to evaluate the effect of enteral glutamine supplementation on clinical outcomes, gut permeability, systemic inflammation, oxidative stress, and plasma glutamine levels in patients with severe and predicted severe AP., Methods: Patients with AP admitted within 72 h of onset of symptoms were included. The primary outcome measure was development of infected pancreatic and peri-pancreatic necrosis and in-hospital mortality. High-sensitivity C-reactive protein (HS-CRP) and interleukin-6 (IL-6) were evaluated as markers of inflammation; plasma thiobarbituric acid reactive substances (TBARS) and activities of serum superoxide dismutase and glutathione peroxidase were determined to evaluate oxidative stress; serum polyethylene glycol (PEG) was tested for intestinal permeability; subjective global assessment (SGA) was used for nutritional assessment, and an improvement in organ function was measured by the Modified Marshall score. Intention-to-treat analysis was used. A p-value of < 0.05 was considered statistically significant., Results: After power calculation, we enrolled 18 patients in the glutamine and 22 in the control arm. There was no significant improvement in the development of infected necrosis and in-hospital mortality between the groups. Improvement in Modified Marshall score was observed in a higher proportion of patients receiving glutamine (15 [83.3%] vs. 12 [54.5%]; p = 0.05). Plasma glutamine levels improved more in glutamine-treated group (432.72 ± 307.83 vs. 618.06 ± 543.29 μM/L; p = 0.004), while it was lower in controls (576.90 ± 477.97 vs. 528.20 ± 410.45 μM/L; p = 0.003). PEG level was lower after glutamine supplementation (39.91 ± 11.97 vs. 32.30 ± 7.39 ng/mL; p = 0.02). Statistically significant reduction in IL-6 concentration was observed in the glutamine group at the end of treatment (87.44 ± 7.1 vs. 63.42 ± 33.7 μM/L; p = 0.02)., Conclusions: Despite absence of improvement in infected necrosis and in-hospital mortality, enteral glutamine supplementation showed improvement in gut permeability, oxidative stress, and a trend towards improvement in organ function as depicted by improvement in the Modified Marshall score., Trial Registration: NCT01503320.

The gut microbiome increasingly is recognized for its role in human health and disease. Initial evidence has indicated that gut microbial dysbiosis is associated with several pancreatic diseases. Although it is not known if these associations are causative, gut dysbiosis is hypothesized to mediate chronic proinflammatory changes in the pancreas. Further mechanistic and epidemiologic studies of the microbiome are needed. Ultimately, targeted modulation of the microbiota could have therapeutic value., (Copyright © 2019 AGA Institute.

Abdominal pain is an important symptom in most patients with pancreatic ductal adenocarcinoma (PDAC). Adequate control of pain is often unsatisfactory due to limited treatment options and significant variation in local practice, emphasizing the need for a multidisciplinary approach. This review contends that improvement in the management of PDAC pain will result from a synthesis of best practice and evidence around the world in a multidisciplinary way. To improve clinical utility and evaluation, the evidence was rated according to the GRADE guidelines by a group of international experts. An algorithm is presented, which brings together all currently available treatment options. Pain is best treated early on with analgesics with most patients requiring opioids, but neurolytic procedures are often required later in the disease course. Celiac plexus neurolysis offers medium term relief in a substantial number of patients, but other procedures such as splanchnicectomy are also available. Palliative chemotherapy also provides pain relief as a collateral benefit. It is stressed that the assessment of pain must take into account the broader context of other physical and psychological symptoms. Adjunctive treatments for pain, depression and anxiety as well as radiotherapy, endoscopic therapy and neuromodulation may be required in selected patients. There are few comparative studies to help define which combination and order of these treatment options should be applied. New pain therapies are emerging and could for example target neural transmitters. However, until better methods are available, management of pain should be individualized in a multidisciplinary setting to ensure optimal care., (Copyright © 2018 IAP and EPC. All rights reserved.)

Mutations in PRSS1 gene namely R122H and N29I cause hereditary pancreatitis. They are autosomal dominant with a high penetrance (80%) reported in North American, North-east Asian, and North European ethnicities. However, the mutations are reportedly absent in Indian, African, and South American ethnicities. We report here for the first time a family from India that is positive for R122H mutation in the PRSS1 gene. The proband is symptomatic with chronic pancreatitis, however, the father although heterozygous for R122H is asymptomatic.

Background: Gastroesophageal reflux disease (GERD) is the most common chronic gastrointestinal disorder, affecting one third of the population worldwide. Recently, there has been a renewed interest in Stretta therapy in view of potential long-term side effects of PPIs and the durability of relief with fundoplication., Method: Prospective randomized study comparing the Stretta treatment with controls receiving PPIs. Patient (> 18 years, n = 20) with symptoms of heartburn, regurgitation, abnormal esophageal acid exposure (≥ 4%), and endoscopically confirmed esophagitis were included into the study. The primary measure was improvement in quality of life (QOL) and decrease in the frequency and severity of GERD symptoms., Results: The mean age of the patients was 39 (± 15) years and controls were 34 (± 11) years. Three months after Stretta, 80% reported improvement in QOL compared to 40% in the control group. At the end of 3 months, significant (p < 0.05) improvement in GERD symptom score for heartburn, regurgitation, chest pain, and cough compared with the control group was observed. After Stretta treatment, 60% of the patients were free of PPIs whereas there was no change in the control group. Almost 80% of the patients on Stretta treatment were satisfied with the treatment compared to 30% of the patients in the control group., Conclusion: Stretta was effective in the short-term for the management of GERD.

The objective of the present review is to focus on pancreatic exocrine insufficiency that is associated with Type 1 and 2 diabetes, its clinical and therapeutic implications, including the utility and efficacy of pancreatin supplementation. A literature search was conducted on Pubmed / Medline to identify relevant articles using terms pancreatic exocrine insufficiency in diabetes mellitus patients, pathophysiology, prevalence, treatment and management published between 2006-2016 in English language. Meta-analysis has revealed the prevalence of PEI in patients with type-1 and type-2 diabetes mellitus to be 37.7% (CI 27.2-49.5) and 26.2% (CI 19.4-34.3) respectively. Very scanty data are available that evaluates the efficacy of pancreatin in patients with diabetes. In the available studies, pancreatin was found to reduce hypoglycemia in insulin treated patients. Pancreatic exocrine insufficiency in type 1 and 2 diabetes mellitus is not uncommon and correct use of pancreatin may have a positive effect on the glycemic status of the diabetic patients., (© Journal of the Association of Physicians of India 2011.)

Background and Aims: EUS-guided drainage using plastic stents may be inadequate for treatment of walled-off necrosis (WON). Recent studies report variable outcomes even when using covered metal stents. The aim of this study was to evaluate the efficacy of a dedicated covered biflanged metal stent (BFMS) when adopting an endoscopic "step-up approach" for drainage of symptomatic WON., Methods: We retrospectively evaluated consecutive patients with symptomatic WON who underwent EUS-guided drainage using BFMSs over a 3-year period. Reassessment was done between 48 and 72 hours for resolution. Endoscopic reinterventions were tailored in nonresponders in a stepwise manner. Step 1 encompassed declogging the blocked lumen of the BFMS. In step 2, a nasocystic tube was placed via BFMSs with intermittent irrigation. Step 3 involved direct endoscopic necrosectomy (DEN). BFMSs were removed between 4 and 8 weeks of follow-up. The main outcome measures were technical success, clinical success, adverse events, and need for DEN., Results: Two hundred five WON patients underwent EUS-guided drainage using BFMSs. Technical success was achieved in 203 patients (99%). Periprocedure adverse events occurred in 8 patients (bleeding in 6, perforation in 2). Clinical success with BFMSs alone was seen in 153 patients (74.6%). Reintervention adopting the step-up approach was required in 49 patients (23.9%). Incremental success was achieved in 10 patients with step 1, 16 patients with step 2, and 19 patients with step 3. Overall clinical success was achieved in 198 patients (96.5%), with DEN required in 9.2%. Four patients failed treatment and required surgery (2) or percutaneous drainage (2)., Conclusions: The endoscopic step-up approach using BFMSs was safe, effective, and yielded successful outcomes in most patients, reducing the need for DEN., (Copyright © 2017 American Society for Gastrointestinal Endoscopy.

The incidence of acute pancreatitis (AP) is increasing globally and mortality could be high among patients with organ failure and infected necrosis. The predominant factors responsible for the morbidity and mortality of AP are systemic inflammatory response syndrome and multiorgan dysfunction. Even though preclinical studies have shown antisecretory agents (somatostatin), antioxidants (S-adenosyl methionine [SAM], selenium), protease inhibitors, platelet activating factor inhibitor (Lexipafant), and anti-inflammatory immunomodulators (eg. prostaglandin E, indomethacin) to benefit AP in terms of reducing the severity and/or mortality, most of these agents have shown heterogeneous results in clinical studies. Several years of experimental studies have implicated nuclear factor-kappa B (NF-κB) activation as an early and central event in the progression of inflammation in AP. In this manuscript, we review the literature on the role of NF-κB in the pathogenesis of AP, its early intraacinar activation, and how it results in progression of the disease. We also discuss why anti-protease, antisecretory, and anti-inflammatory agents are unlikely to be effective in clinical acute pancreatitis. NF-κB, being a central molecule that links the initial acinar injury to systemic inflammation and perpetuate the inflammation, we propose that more studies be focussed towards targeted inhibition of NF-κB activity. Direct NF-κB inhibition strategies have already been attempted in patients with various cancers. So far, peroxisome proliferator activator receptor gamma (PPAR-γ) ligand, pyrrolidine dithiocarbamate (PDTC), proteasome inhibitor and calpain I inhibitor have been shown to have direct inhibitory effects on NF-κB activation in experimental AP., (Copyright © 2016 IAP and EPC.

Relation between the gut microbiota and human health is being increasingly recognised. It is now well established that a healthy gut flora is largely responsible for overall health of the host. The normal human gut microbiota comprises of two major phyla, namely Bacteroidetes and Firmicutes. Though the gut microbiota in an infant appears haphazard, it starts resembling the adult flora by the age of 3 years. Nevertheless, there exist temporal and spatial variations in the microbial distribution from esophagus to the rectum all along the individual's life span. Developments in genome sequencing technologies and bioinformatics have now enabled scientists to study these microorganisms and their function and microbe-host interactions in an elaborate manner both in health and disease. The normal gut microbiota imparts specific function in host nutrient metabolism, xenobiotic and drug metabolism, maintenance of structural integrity of the gut mucosal barrier, immunomodulation, and protection against pathogens. Several factors play a role in shaping the normal gut microbiota. They include (1) the mode of delivery (vaginal or caesarean); (2) diet during infancy (breast milk or formula feeds) and adulthood (vegan based or meat based); and (3) use of antibiotics or antibiotic like molecules that are derived from the environment or the gut commensal community. A major concern of antibiotic use is the long-term alteration of the normal healthy gut microbiota and horizontal transfer of resistance genes that could result in reservoir of organisms with a multidrug resistant gene pool.

Background: Pain in CP results from inflammation and neuroimmune alterations that are associated with oxidative stress, among other mechanisms. This is marked by depletion of antioxidant defenses including methionine, which is a donor of methyl moieties that maintains the acinar transsulfuration pathway. We performed a systematic review and meta-analysis of trials evaluating methionine-containing antioxidants in CP., Patient and Methods: Literature search was conducted in Medline/Pubmed, EMBASE, and Cochrane databases. Systematic review and meta-analysis was performed per PRISMA guidelines. Main study outcome was pain relief. GRADE system was used for quality assessment. Heterogeneity was assessed by the Q and I(2) measures; publication bias by Egger's test. Random-effect model (DerSimonian and Laird) was used if there was heterogeneity., Results: Eight studies (n = 411) were identified that used methionine-containing antioxidants. The study duration ranged from 10 wks to 12 months. All studies used methionine, organic selenium, ascorbate, beta-carotene and alpha-tocoferol. Four studies (including two RCTs) that reported change in pain scores were metaanalyzed. Though overall effect [standardized difference in means (95% CI)] on pain score reduction was -0.95 (-1.738 to -0.160) (z = -2.36; p = 0.018), the significance was lost when the two RCTs were meta-analyzed. RCTs that reported the number of pain free patients had a statistically significant overall effect of -3.204 (p = 0.001). Though more patients on methionine containing antioxidants had adverse events, majority of them were mild., Conclusion: Methionine containing antioxidants appear to result in pain reduction in a significant proportion of CP patients. Further randomized controlled trials with homogeneous outcome measures are needed., (Copyright © 2015 IAP and EPC. Published by Elsevier B.V. All rights reserved.)

Aim: To evaluate the ability of contrast-enhanced computerized tomography (CECT) to characterize the nature of peripancreatic collections., Methods: Twenty five patients with peripancreatic collections on CECT and who underwent operative intervention for severe acute pancreatitis were retrospectively studied. The collections were classified into (1) necrosis without frank pus; (2) necrosis with pus; and (3) fluid without necrosis. A blinded radiologist assessed the preoperative CTs of each patient for necrosis and peripancreatic fluid collections. Peripancreatic collections were described in terms of volume, location, number, heterogeneity, fluid attenuation, wall perceptibility, wall enhancement, presence of extraluminal gas, and vascular compromise., Results: Fifty-four collections were identified at operation, of which 45 (83%) were identified on CECT. Of these, 25/26 (96%) had necrosis without pus, 16/19 (84%) had necrosis with pus, and 4/9 (44%) had fluid without necrosis. Among the study characteristics, fluid heterogeneity was seen in a greater proportion of collections in the group with necrosis and pus, compared to the other two groups (94% vs 48% and 25%, P = 0.002 and 0.003, respectively). Among the wall characteristics, irregularity was seen in a greater proportion of collections in the groups with necrosis with and without pus, when compared to the group with fluid without necrosis (88% and 71% vs 25%, P = 0.06 and P < 0.01, respectively). The combination of heterogeneity and presence of extraluminal gas had a specificity and positive likelihood ratio of 92% and 5.9, respectively, in detecting pus., Conclusion: Most of the peripancreatic collections seen on CECT in patients with severe acute pancreatitis who require operative intervention contain necrotic tissue. CECT has a somewhat limited role in differentiating the different types of collections.

Primary orbital lymphoma is a rare condition involving primarily the lacrimal glands. We present the second Indian case of right-sided primary orbital lymphoma in an elderly male who presented with the typical features and showed a good response to chemotherapy.

Let alone the eradication, malaria control itself has amounted to be a challenge, and is detrimental to the all round development of the northeastern region of India. Focal outbreaks are frequent taking heavy tool on human lives. Plasmodium falciparum is the predominant parasite species and is solely responsible for increased morbidity and mortality. The region contributes bulk of P. falciparum cases for the rest of India, and its proportions are increasing. Efficient vectors like Anopheles minimus, Anopheles fluviatilis and Anopheles dirus persistently support transmission of malaria. The present review gives a comprehensive account of the factors responsible for transmission of the disease with focus on vector bionomics, its prevention and control.
