Endoscopic Ultrasound-Guided Rendezvous Technique Versus Precut Sphincterotomy as Salvage Technique in Patients With Benign Biliary Disease and Difficult Biliary Cannulation : A Randomized Controlled Trial.

BACKGROUND: The standard salvage technique used for difficult bile duct cannulation is precut sphincterotomy, whereas endoscopic ultrasound-guided rendezvous technique (EUS-RV) is a relatively newer method. Prospective comparative data between these 2 techniques as salvage for biliary access in patients with benign biliary disease and difficult bile duct cannulation is lacking. OBJECTIVE: To compare EUS-RV and precut sphincterotomy as salvage technique for difficult bile duct cannulation in benign biliary obstruction. DESIGN: Participant-masked, parallel-group, superiority, randomized controlled trial. (Clinical Trials Registry of India: CTRI/2020/07/026613). SETTING: Tertiary care academic institute from July 2020 to May 2021. PARTICIPANTS: All patients with benign biliary disease and difficult bile duct cannulation requiring salvage strategy. INTERVENTION: Patients were randomly assigned by computer-generated randomized blocks sequence in 1:1 fashion to either EUS-RV or precut sphincterotomy. Patients with failure in EUS-RV were crossed over to precut sphincterotomy and vice versa. MEASUREMENTS: The primary outcome measure was technical success. The other outcome measures included procedure time, radiation dose, and adverse events. RESULTS: In total, 100 patients were randomly assigned to EUS-RV (n = 50) and precut sphincterotomy (n = 50). The technical success rate (92% vs. 90%; P = 1.00; relative risk, 1.02 [95% CI, 0.90 to 1.16]), median procedure time (10.1 vs. 9.75 minutes), and overall complication rate (12% vs. 10%; relative risk, 1.20 [CI, 0.39 to 3.68]) were similar between the 2 groups. Five patients (10%) in the EUS-RV group and 5 patients (10%) in the precut sphincterotomy group had developed post-endoscopic retrograde cholangiopancreatography pancreatitis. All failed cases in either salvage group could be successfully cannulated when crossed over to the other group. LIMITATION: Single center study done by experts. CONCLUSION: Endoscopic ultrasound-guided rendezvous technique and precut sphincterotomy have similar success rates as salvage techniques in the technically challenging cohort of difficult bile duct cannulation for benign biliary disease, with acceptable complications rates. PRIMARY FUNDING SOURCE: None.

Buprenorphine Versus Diclofenac for Pain Relief in Acute Pancreatitis: A Double-Blinded Randomized Controlled Trial.

BACKGROUND: Although both nonsteroidal anti-inflammatory drugs (NSAIDs) and opioids are used for analgesia in acute pancreatitis (AP), the analgesic of choice is not known. We compared buprenorphine, an opioid, and diclofenac, an NSAID, for analgesia in AP. METHODS: In a double-blind randomized controlled trial, AP patients were randomized to receive intravenous diclofenac or intravenous buprenorphine. Fentanyl was used as rescue analgesia, delivered through a patient-controlled analgesia pump. Primary outcome was the difference in the dose of rescue fentanyl required. Secondary outcomes were the number of effective and ineffective demands of rescue fentanyl, pain-free interval, reduction in visual analogue scale (VAS) score, adverse events, and organ failure development. RESULTS: Twenty-four patients were randomized to diclofenac and 24 to buprenorphine. The 2 groups were matched at baseline. The total amount of rescue fentanyl required was significantly lower in the buprenorphine group:130 µg, interquartile range (IQR), 80-255 vs 520 µg, IQR, 380-1065 (P < .001). The number of total demands was 32 (IQR, 21-69) in the diclofenac arm vs 8 (IQR, 4-15) in the buprenorphine arm (P < .001). The buprenorphine group had more prolonged pain-free interval (20 vs 4 hours; P < .001), with greater reduction in the VAS score at 24, 48, and 72 hours compared with the diclofenac group. These findings were confirmed in the subgroup of moderately severe/severe pancreatitis. Adverse events profile was similar in the 2 groups. CONCLUSIONS: Compared with diclofenac, buprenorphine appears to be more effective and equally safe for pain management in AP patients, even in the subcohort of moderately severe or severe pancreatitis (Trial Registration number: CTRI/2020/07/026914).

Unusual Sites of Necrotic Collections in Acute Necrotizing Pancreatitis: Association with Parenchymal Necrosis and Clinical Outcomes.

BACKGROUND: The presence of necrotic collection in acute necrotizing pancreatitis (ANP) at intra-abdominal sites other than the retroperitoneum has not been systematically studied. AIM: To investigate unusual sites of necrotic collections at computed tomography (CT) and to evaluate association with pancreatic necrosis and clinical outcomes. METHODS: This retrospective study comprised of consecutive patients with ANP evaluated between January 2018 and March 2019. Based on CT findings, patients were divided into two groups: collections at unusual sites (small bowel mesentery, mesocolon, omentum, subcapsular collections along liver and spleen, pelvis, anterior abdominal wall, and inguinoscrotal regions) and collections at usual retroperitoneal locations (lesser sac, gastrosplenic location, anterior and posterior pararenal spaces, and paracolic gutters). The differences in CT findings and clinical outcomes (need for drainage, length of hospitalization, intensive care unit admission, surgery, and death) between the two groups were evaluated. RESULTS: A total of 75 patients with ANP were evaluated. There were 25 (33.3%) patients with collections in unusual locations. These included mesentery (n = 17), splenic subcapsular location (n = 7), omentum (n = 6), hepatic subcapsular location (n = 4), anterior abdominal wall (n = 3), pelvis (n = 2), and inguinoscrotal location (n = 1). Compared to patients with collections at usual locations (n = 50), there were no differences in the CT findings except complete parenchymal necrosis (32% vs. 0%, P = .001). There were no statistically significant differences in the clinical outcomes between the two groups. CONCLUSIONS: Mesenteric collections are frequent in ANP. The other non-retroperitoneal sites are infrequently involved. There is no association between unusual sites of collection and clinical outcomes.

Natural history and profile of selective cytokines in patients of acute pancreatitis with acute kidney injury.

OBJECTIVES: To study the natural course of patients with acute pancreatitis (AP) with acute kidney injury (AKI) and their cytokine profile. METHODS: Natural course of patients with AP and AKI was studied in 97 individuals. Levels of TNFα, IL-6, IL-10, IL-8 and IL-1ß were measured at presentation and at 72 h in patients who developed AKI. RESULTS: Amongst the entire cohort, 16.4% patients developed AKI (persistent AKI - 11 patients, transient AKI - 5 patients). Mortality rate was 25% amongst patients with AKI. Levels of IL-6 (p = 0.035) and IL-8 (p = 0.002) were found to be significantly higher in the AKI group. On multivariate analysis, IL-8 levels at baseline were found to be an independent predictor of AKI. AKI group had significant rise of TNF-α (P < 0.001), IL-6 (P < 0.001) and IL- 1ß (P < 0.001) on day 3 whereas persistent-AKI group had significant rise of TNF-α (p = 0.031), IL-6 (p = 0.001) and IL-1ß on day 3 and significant decline of IL-10 (p = 0.015). Using a cut-off of 105 pg/ml, IL-8 levels at baseline could predict AKI with a sensitivity of 87.5% and specificity of 59.2%, with area under the curve being 0.744 (p = 0.002). CONCLUSION: AP patients developing AKI have poor prognosis. IL-8 levels can predict AKI in patients with AP.

Predictors of outcome of percutaneous catheter drainage in patients with acute pancreatitis having acute fluid collection and development of a predictive model.

BACKGROUND: Percutaneous catheter drainage (PCD) is effective initial strategy in the step-up approach of management of acute pancreatitis (AP). The objective of this study was to identify factors associated with outcomes after PCD and develop a predictive model. METHOD AND MATERIALS: In a prospective observational study between July 2016 and Nov 2017, 101 consecutive AP patients were treated using a "step-up approach" in which PCD was used as the first step. We evaluated the association between success of PCD (survival without necrosectomy) and baseline parameters viz. etiology, demography, severity scores, C-reactive protein (CRP), and intra-abdominal pressure (IAP), morphologic characteristics on computed tomography (CT) [percentage of necrosis, CT severity index (CTSI), characteristics of collection prior to PCD (volume, site and solid component of the collection), PCD parameters (initial size, maximum size, number and duration of drainage) and factors after PCD insertion (fall in IAP, reduction in volume of collection). RESULTS: Among 101 patients, 51 required PCD. The success rate of PCD was 66.66% (34/51). Four patients required additional surgical necrosectomy after PCD. Overall mortality was 29.4% (15/51). Multivariate analysis showed percentage of volume reduction of fluid collection (p = 0.016) and organ failure (OF) resolution (p = 0.023) after one week of PCD to be independent predictors of success of PCD. A predictive model based on these two factors resulted in area under curve (AUROC) of 0.915. Nomogram was developed with these two factors to predict the probability of success of PCD. CONCLUSION: Organ failure resolution and reduction in volume of collection after one week of PCD are significant predictors of successful PCD outcomes in patients with fluid collection following AP.

Acute Pancreatitis Caused by Isolated Pancreatic Metastasis From Uterine Choriocarcinoma.

Choriocarcinoma is an aggressive gestational trophoblastic neoplasia known for its widely metastatic potential. However, isolated pancreatic metastasis is an extremely rare occurrence and has not been documented in the English literature to the best of our knowledge. The metastatic deposits in the index case led to widespread hemorrhage and necrosis of the pancreatic parenchyma, causing severe acute pancreatitis. The patient succumbed to her illness before chemotherapy was administered. Thus, we present an autopsy case of a uterine choriocarcinoma with isolated pancreatic metastasis presenting as severe acute pancreatitis in a 27-yr-old woman following a molar pregnancy.

Cytokine profile in prediction of acute lung injury in patients with acute pancreatitis.

OBJECTIVES: To study the role of cytokines in prediction of acute lung injury (ALI) in acute pancreatitis. METHODS: Levels of TNFα, IL-6, IL-10, IL-8 and IL-1ß were measured in 107 patients at presentation and at 72 h in patients who developed acute lung injury. A model was devised to predict development of ALI using cytokine levels and SIRS score. RESULTS: The levels of TNF α (p < 0.0001), IL-6 (p < 0.0001), IL-8 (p < 0.0001) and IL-1ß (p < 0.0001) were significantly higher in the ALI group. IL-10 levels were significantly lower in persistent ALI (p-ALI) than in transient ALI (t-ALI) patients (p < 0.038). p-ALI group had significant rise of TNFα (p = 0.019) and IL-1ß (p = 0.001) while t-ALI group had significant rise of only IL-1ß (p = 0.044) on day 3 vs day 1. Combined values of IL-6 and IL-8 above 251 pg/ml had sensitivity of 90.9% and a specificity of 100% to predict future development of ALI. Composite marker-I (IL6 ≥ 80 pg/ml + SIRS) yielded sensitivity and specificity of 73% and 98% whereas composite marker-II (IL8 ≥ 100 pg/ml + SIRS) yielded sensitivity and specificity of 73% and 95% to predict future ALI. CONCLUSIONS: IL-6 and IL-8 can predict future development of ALI. When they are combined with SIRS, they can be used as comprehensive composite markers.

Plastic versus metal stents for transmural drainage of walled-off necrosis with significant solid debris: a randomized controlled trial.

Background and study aims Recently, larger-caliber metal stents have been increasingly used, resulting in higher efficacy in walled-off necrosis (WON) with more solid debris. However, none of the trials have included WON with significant solid debris. The aim of this study was to compare plastic stents and metal stents for drainage of symptomatic WON with significant solid debris (≥20%). Patients and methods We conducted a single-center, open-label, noninferiority trial including 48 patients. The primary endpoint was treatment success. Secondary outcomes were technical success, total number of procedures, adverse events (AEs), duration of procedure, and treatment failure. All the outcomes were assessed at 3 weeks after drainage. Patients were followed up for 3 months to assess recurrence. Results Treatment succeeded in 21 of 24 patients (87.5%) and 20 of 24 patients (83.3%) in the metal and plastic stent groups, respectively with P =1.05 (95% confidence interval 0.81-1.39). Assuming 10% non-inferiority margin, P <0.001 for non-inferiority, suggesting that plastic stents are non-inferior to metal stents. The technical success rate was 100%. Procedure duration was significantly shorter in the metal stent group (12.95±5.3 minutes versus 29.77±6.6 minutes, P <0.001). The number of total procedures was comparable (2.8±1 vs 2.2±1, P =0.097). There were more minor AEs in plastic stent arm but no significant difference between the two groups. A single asymptomatic recurrence was observed in the metal stent arm. Conclusions Plastic stents are not inferior to metal stents for WON drainage with significant solid debris. However, larger sample-size studies are needed to make definite conclusions.

Endoscopic Ultrasound-guided Drainage of Patients With Infected Walled-off Necrosis: Which Stent to Choose?

BACKGROUND: Endoscopic ultrasound (EUS)-guided drainage is the preferred treatment of pancreatic fluid collections (PFC). However, the choice of the stent for EUS-guided drainage in critically ill PFC cases with infected walled-off necrosis (WON) and/or organ failure (OF) remains unknown. MATERIALS AND METHODS: Between January 2018 and December 2019, consecutive patients with symptomatic PFC subjected to EUS-guided drainage using biflanged metal stents (BFMS) or double-pigtail plastic stents (DPPS) were compared for technical success, clinical success, duration of the procedure, need for intensive care unit stay, duration of intensive care unit stay, ventilator need, resolution of OF, the duration for resolution of OF, complications, need for salvage percutaneous drainage or surgery and mortality. A subgroup of patients having infected WON with/without OF were analyzed separately. RESULTS: Among 120 patients (84.6% males) with PFC (108 WON, 22 pseudocyst) who underwent EUS-guided drainage, there was no difference in outcome parameters in BFMS and DPPS groups. Among patients with WON, clinical success was significantly higher (96.2% vs. 81.8%, P=0.04), with significantly shorter hospital stay (6 vs. 10 d) and procedure duration (17.18±4.6 vs. 43.6±9.7 min, P<0.0001) in the BFMS group. Among patients with infected WON with/without OF, the clinical success was significantly higher (100% vs. 73.9%, P=0.02), and the duration of the procedure was significantly lower (16.28±4.4 vs. 44.39±10.7, P<0.0001) in BFMS compared with DPPS group. CONCLUSION: EUS-guided drainage of WON using BFMS scores over DPPS. In patients having infected WON with/without OF, BFMS may be preferred over DPPS.

Endoscopic drainage versus percutaneous drainage for the management of infected walled-off necrosis: a comparative analysis.

BACKGROUND: Comparative data on percutaneous catheter drainage (PCD) vs EUS-guided drainage (EUS-D) for management of symptomatic walled-off-necrosis (WON), specially infected WON with/without organ failure(OF) is limited. METHODS: Patients with symptomatic WON were divided into two groups of PCD and EUS-D, depending on the modality of drainage. Resolution of OF, adverse events, and other outcome measures were recorded. The two modalities were compared among infected WON sub-cohort and also degree of solid component (SC). RESULTS: 218 patients (175 males; 80.3%) were included who underwent either PCD (n = 102) or EUS-D (n = 116). Clinical success was significantly higher in the EUS-D group (92.1% vs 64.6%; p < 0.0001) and even for infected WON (n = 128) (p = 0.004), with higher (p = 0.007) and faster (p < 0.0001) OF resolution. Other outcome measures including mortality were significantly higher in the PCD group. Among subgroups, PCD with >40% SC had the worst clinical success/OF resolution rates, while EUS-D with <40% SC had the best outcomes. CONCLUSION: EUS-D should be preferred over PCD in the management of WON, infected or otherwise, for higher clinical success, and higher/faster resolution of OF. PCD should be avoided in WON with>40% SC.

A Systematic Review and Meta-analysis of Opioids vs Nonopioids in Acute Pancreatitis.

Background and Aims: Although abdominal pain is one of the major criteria to diagnose acute pancreatitis (AP), there are no standardized guidelines to treat this troublesome symptom in the hospital setting. The aims of the study are to conduct a meta-analysis and to assess the efficacy of nonopioids vs opioids for pain management in AP. Methods: We searched the medical literature through May 2021 to identify randomized controlled trials that examined the efficacy of opioids with nonopioids in AP pain management. Efficacy was reported as odds ratio (OR) with 95% confidence intervals (CIs) of each comparison tested. Results: We identified 7 eligible randomized controlled trials, containing 389 patients. No significant difference in terms of pain intensity at day 1 (OR 0.82, 95% CI -2.55 to 4.19) was found between opioids and nonopioids. Nonopioids have a significantly high risk of supplementary analgesic use compared with opioids (OR 3.87, 95% CI 1.25-12.04). However, this significance is not seen when comparing nonsteroidal anti-inflammatory drugs and paracetamol with opioids (OR 1.67, 95% CI 0.73-3.82) after excluding trials with procaine. Opioids did not show a significant increase in the complications of pancreatitis, nausea and vomiting, sedation, and deaths when compared with nonopioids. Conclusion: We found nonopioids, especially nonsteroidal anti-inflammatory drugs and paracetamol, can provide adequate pain relief in patients with AP with no change in supplementary analgesic use and adverse events when compared with opioids. Further research is needed to optimize the use of nonopioids along or in combination with opioids for better pain control in patients with AP.

Hepatic artery pseudoaneurysm secondary to a cholangitic abscess and its spontaneous thrombosis.

Hepatic artery pseudoaneurysm (HAP) is mostly encountered secondary to trauma or iatrogenic causes. HAP associated with cholangitic liver abscess is a rare complication. We present a case of gallstone disease and choledocholithiasis who developed moderate cholangitis and a liver abscess. A small HAP was detected incidentally on a biphasic CT done to evaluate the biliary system. Repeat CT after management with endoscopic retrograde cholangiopancreatography and antibiotics showed resolution of cholangitic abscess with spontaneous thrombosis of HAP.

An unusual cause of granulomatous colitis: Behcet's disease.

Intestinal involvement in Behcet's disease (BD) is uncommon. Differentiating it from close mimics like Crohn's Disease is difficult. Further, in asymptomatic cases, diagnostic challenges posed is still greater. A 17-year-old boy had history of recurrent oro-genital ulcers, papulo-pustular skin eruptions, ocular lesions and had presented with recent onset perianal abscess. Fecal calprotectin was elevated, and ileo-colonoscopy showed ileocolonic ulcers of inflammatory nature. Clinical diagnosis of intestinal BD was made. Patients with BD having mucosal lesions may harbor asymptomatic intestinal lesions. Screening them with fecal calprotectin levels and if positive, with subsequent imaging and endoscopic biopsy with timely initiation of appropriate treatment in such asymptomatic cases help to control overall disease activity.

Delayed referral increases the need for surgery and intervention in patients with acute pancreatitis.

BACKGROUND: The aim was to study the outcomes of acute pancreatitis (AP) patients who were referred from other facilities to a tertiary care centre. METHODS: Patients with AP were who were referred from other hospitals to a tertiary care centre between April 2013 and September 2019 were studied and their outcomes were analysed. Comparison was made between patients referred early (≤7 days) versus those referred late (>7 days). RESULTS: Of the 838 patients seen by us, 650 patients (77.6%) were referred from other centres. Median (interquartile range) onset to admission interval was 5 (4-7) days for those who were referred ≤7 days and was 16 (11-30) for those who were referred >7 days. Patients referred beyond 7 days of pain onset had higher rates of development of organ failure (P = 0.007), including acute lung injury (P = 0.008) and acute kidney injury (P = 0.026), infected necrosis (P < 0.0001), requirement of endoscopic/percutaneous drainage (P < 0.001) and need for surgery (P < 0.02) compared to patients who were referred ≤7 days of pain onset. Mortality was however similar in the two groups. CONCLUSION: Patients with AP referred to a specialized centre with AP early (≤7 days) have better outcomes than those referred late (>7 days) from other facilities.

Can high-frequency mini-probe endoscopic ultrasonography predict outcome of endoscopic dilation in patients with benign esophageal strictures?

Background and study aims Endoscopic dilation is first-line management for benign esophageal strictures (ES). Depth of involvement of the esophageal wall on endosonography using high frequency mini-probe (EUS-M) may predict response to dilation. This study evaluated EUS-M characteristics to predict response of ES to endoscopic dilation. Patients and methods EUS-M was used to measure the total esophageal wall thickness (EWT), involved EWT, percentage of involved wall and layers of wall involved in consecutive patients of benign ES. After a maximum of five sessions of endoscopic dilation, the cohort was divided into responders and refractory strictures. EUS-M characteristics were compared for underlying etiology as also between responders and refractory strictures. Results Of the 30 strictures (17 females, age: 47.16 ±â€Š15.86 yrs.) 13 were anastomotic, eight corrosive, seven peptic and 2 others. Corrosive strictures had the highest involved EWT and percentage of involved wall (3.51 ±â€Š1.36 mm; 76.38 %) followed by anastomotic (2.73 ±â€Š1.7 mm; 65.54 %) and peptic (1.39 ±â€Š0.62 mm; 40.71 %) ( P  = 0.026 and 0.021 respectively). After five dilations, 22 were classified as responders and eight as refractory. Wall involvement > 70 % had a greater proportion of refractory strictures ( P  = 0.019). Strictures with involved EWT of ≥ 2.85 mm required more dilations ( P  = 0.011). Fewer dilations were required for stricture resolution with only mucosal involvement compared to deeper involvement such as submucosa and muscularis propria (2.14 vs. 5.80; P  = 0.001). Conclusion EUS-M evaluation shows that corrosive and anastomotic strictures have greater depth of involvement compared to peptic strictures. Depth of esophageal wall involvement in a stricture predicts response to dilation.

Comparison of efficacy of diclofenac and tramadol in relieving pain in patients of acute pancreatitis: A randomized parallel group double blind active controlled pilot study.

BACKGROUND: Opioids and non steroidal anti inflammatory drugs (NSAIDs) are commonly used for pain relief in acute pancreatitis (AP). Opioids carry risk of sphincter of oddi constriction. Although diclofenac prevents post endoscopic retrograde cholangio-pancreatography (ERCP) pancreatitis, few reports of diclofenac associated AP are also present. Although, both tramadol and diclofenac are commonly used for pain relief in AP, no study has evaluated their comparative efficacy and safety. MATERIALS AND METHODS: Forty-six eligible participants were randomized to either diclofenac or tramadol. Primary objectives of our study were improvement in pain intensity on visual analogue scale (VAS pain score after 1 hr of drug administration) and number of patients requiring supplementary analgesia. The secondary objectives were total number of times of supplementary analgesia requirement, time to significant decrease (33%) in VAS pain score from baseline, number of painful days (VAS pain score >5), VAS pain score on 7th day, side effects, all cause death and complications of pancreatitis between the two groups. RESULTS: Although 46 patients were randomized, the final analysis included 41 participants. Five patients were withdrawn from the study (intubation = 3, altered sensorium = 2). No significant difference was seen in terms of VAS score after 1 hr of drug administration, number of patients requiring supplementary analgesic and number of painful days. However, time taken to significant reduction of pain was lower in the diclofenac group (p = .028). Both the agents were comparable in terms of safety. Although complications were less in the diclofenac group, the difference was not statistically significant. CONCLUSION: Both diclofenac and tramadol are equally effective in controlling pain in AP with similar safety profile. SIGNIFICANCE: There are no studies that have compared the safety and efficacy of two commonly used analgesics for pain relief in patients with AP. We found that both diclofenac and tramadol are equally effective in decreasing the pain associated with AP. There is also no significant difference in the incidence of side effects between both the groups. Hence both diclofenac and tramadol can be used safely and effectively for pain control in AP. TRIAL REGISTRATION: The trial was registered with clinical trials registry India (Number- CTRI/2018/05/014309).

Efficacy and safety of steroid therapy in COVID-19: A rapid systematic review and Meta-analysis.

PURPOSE: Although the use of steroids in the management of COVID-19 has been addressed by a few systematic review and meta-analysis, however, they also used data from "SARS-CoV" and "MERS-CoV." Again, most of these studies addressed only one severity category of patients or addressed only one efficacy endpoint (mortality). In this context, we conducted this meta-analysis to evaluate the efficacy and safety of steroid therapy among all severity categories of patients with COVID-19 (mild to moderate and severe to critical category) in terms of "mortality," "requirement of mechanical ventilation," "requirement of ICU" and clinical cure parameters. METHODS: 11 databases were screened. Only randomized controlled trials (RCTs) or high quality (on the basis of risk of bias analysis) comparative-observational studies were included in the analysis. RevMan5.3 was used for the meta-analysis. RESULTS: A total of 15 studies (3 RCT and 12 comparative-observational studies) were included. In the mechanically-ventilated COVID-19 population, treatment with dexamethasone showed significant protection against mortality (single study). Among severe and critically ill combined population, steroid administration was significantly associated with lowered mortality (risk ratio [RR] 0.83 [0.76-0.910]), lowered requirement of mechanical ventilation (RR 0.59 [0.51-0.69]), decreased requirement of intensive care unit (ICU) (RR 0.62 [0.45-0.86]), lowered length of ICU stay (single-study) and decreased duration of mechanical ventilation (two-studies). In mild to moderate population, steroid treatment was associated with a higher "duration of hospital stay," while no difference was seen in other domains. In patients at risk of progression to "acute respiratory distress syndrome," steroid administration was associated with "reduced requirement of mechanical ventilation" (single-study). CONCLUSION: This study guides the use of steroid across patients with different severity categories of COVID-19. Among mechanically ventilated patients, steroid therapy may be beneficial in terms of reduced mortality. Among "severe and critical" patients; steroid therapy was associated with lowered mortality, decreased requirement of mechanical ventilation, and ICU. However, no benefit was observed in "mild to moderate" population. To conclude, among properly selected patient populations (based-upon clinical severity and biomarker status), steroid administration may prove beneficial in patients with COVID-19.

Utility of narrow band imaging in predicting histology in celiac disease.

BACKGROUND: Narrow band imaging (NBI) with magnification better visualizes the duodenal microsurface and mucosal vascularity. NBI delineates villous atrophy better than conventional white light endoscopy. AIMS: This study was conducted to evaluate the diagnostic accuracy of narrow band imaging with magnification (NBI-ME) in celiac disease (CD). METHODS: In this prospective study, consecutive patients of suspected CD and controls were subjected to tissue transglutaminase antibody test and endoscopic evaluation initially with white light followed by NBI-ME, and biopsies were taken from duodenum. Duodenal villous patterns on NBI were interpreted as normal, blunted distorted, and absent. Severity of villous atrophy was reported according to the modified Marsh criteria. RESULTS: One hundred and twenty-two patients (mean age of 27.53 ± 13.37 years and a male to female ratio of 1:1.26) and 40 controls were studied. The sensitivity and specificity of NBI-ME in predicting villous atrophy were found to be 95.54% and 90%, respectively. The specificity and negative predictive value of NBI-ME in predicting villous atrophy amongst controls was 100% and 97.5%, respectively. Abnormal findings (blunted and absent villous patterns) combined with elevated transglutaminase antibody (> 5-fold) were found to have high accuracy in predicting villous atrophy. CONCLUSION: NBI with magnification has high sensitivity and specificity in predicting villous atrophy in patients with celiac disease.

Patterns of alcohol consumption and nutrition intake in patients with alcoholic liver disease and alcoholic pancreatitis in North Indian men.

BACKGROUND AND AIM: Chronic alcoholism and nutrition play an important role in liver and pancreatic diseases. To compare drinking habits and nutritional data in patients with alcoholic liver disease (ALD) and alcoholic pancreatitis (ALP). METHODS: Clinical, anthropometric, dietary intake, laboratory, and imaging data were recorded in consecutive patients of ALD and ALP. RESULTS: In 150 patients of ALP (n = 76) and ALD (n = 74), the age of starting alcohol consumption (19.03 ± 3.78 vs 18.0 ± 2.59 years) and the mean amount of alcohol consumed per day (165.63 ± 87.99 vs 185.50 ± 113.54 g; P = 0.230) were similar. Patients with ALD consumed alcohol on a daily basis more frequently (90.5 vs 72.3%; P = 0.003) and had a longer duration of alcohol intake (21.6 + 0.2 vs 14.5 + 6.9 years; P < 0.0001) than patients in the ALP group. Binge drinking was more common in patients with ALP compared to patients with ALD (60.5 vs 20.3%); P < 0.0001). Patients with ALP had a lower body mass index (19.9 ± 3.49 vs 22.64 ± 4.88 kg/m2; P = 0.001) and more frequent decrease in mid arm circumference (57.9 vs 44.6%; P = 0.042) and triceps skin fold thickness (67.1 vs 52.7%; P = 0.072) compared to patients with ALD. CONCLUSION: There was no difference in the age of starting alcohol consumption and mean amount of alcohol consumption per day between the groups. Patients with ALD were more likely to be daily drinkers with a longer duration of alcohol intake. However, binge drinking and malnourishment was more common in the ALP group.
