Post-Transplantation Sinusoidal Obstruction Syndrome in Adult Patients with B Cell Acute Lymphoblastic Leukemia Treated with Pretransplantation Inotuzumab.

Sinusoidal obstruction syndrome (SOS) is a potentially life-threatening complication that can be observed after allogeneic hematopoietic cell transplantation (HCT). Inotuzumab ozogamicin is an anti-CD22 monoclonal antibody-drug conjugate that has demonstrated high efficacy in relapsed/refractory (R/R) acute lymphoblastic leukemia (ALL) but is associated with an increased risk of SOS in HCT recipients. Here we aimed to examine the incidence and outcomes of SOS in 47 adult patients with R/R ALL who received inotuzumab therapy and subsequently underwent HCT at our institution. All patients received prophylactic therapy with ursodiol, and continuous low-dose heparin also was administered to patients receiving myeloablative conditioning (MAC). SOS occurred in 12 patients (26%) post-HCT, at a median onset of 11 days (range, 3 to 41 days). SOS was graded as very severe in 50% (n = 6), severe in 25% (n = 3), and mild in 25% (n = 3). All patients diagnosed with SOS received treatment with defibrotide for a median of 21 days (range, 3 to 34 days), with resolution of SOS occurring in 8 patients (67%). Mortality from SOS was 33% (n = 4) and occurred at a median of 10 days from diagnosis (range, 3 to 31 days) in patients graded as very severe (n = 3) or severe (n = 1). There were no significant differences between patients who developed SOS and those who did not develop SOS in the median time from the last dose of inotuzumab to transplantation (46 days versus 53 days; P = .37), use of an MAC regimen (42% versus 49%; P = .75), number of lines of therapy prior to inotuzumab (P = .79), median number of administered cycles of inotuzumab (2 versus 2; P = .14), or receipt of inotuzumab as the last therapy prior to HCT (67% versus 66%; P = 1.0). Sirolimus-based graft-versus-host disease (GVHD) prophylaxis was used more frequently in the SOS group (75% versus 29%; P < .01), but there was no between-group difference in the peak sirolimus level (P = .81) or the median time to peak sirolimus level (7 days versus 3.5 days; P = .39). In univariable analysis, only the use of sirolimus-based GVHD prophylaxis was significantly associated with an increased risk of SOS (hazard ratio [HR], 7.50; 95% confidence interval [CI], 1.7 to 33.6; P < .01). In the SOS group, the 100-day mortality rate was 33% (n = 4), and median overall survival (OS) post-HCT was 4.3 months (range, 0.2 to 57.2 months). In the group without SOS, the 100-day mortality rate was 14% (n = 5) and the median OS post-HCT was 10.7 months (range, .52 to 39.6 months). In this study cohort, SOS was prevalent in HCT recipients who had been treated with inotuzumab prior to transplantation, and sirolimus-based GVHD prophylaxis was a risk factor for SOS in inotuzumab recipients.

Incidence and predictors of 30-day hospital readmissions for liver cirrhosis: insights from the United States National Readmissions Database.

BACKGROUND: Cirrhosis is associated with substantial inpatient morbidity and mortality. This study aimed to determine the trends in 30-day hospital readmission rates among patients with cirrhosis and identify factors associated with these readmissions. METHODS: We conducted a retrospective analysis of data retrieved from the Nationwide Readmissions Database to determine trends in 30-day readmission for patients discharged with a diagnosis of cirrhosis in 2010 through 2014. Multivariate logistic regression analysis was used to identify predictors of readmission. RESULTS: Among 303,346 patients identified from the database, the 30-day readmission rate for patients with a discharge diagnosis of cirrhosis was 31.4% (n=95,298). The trends in the readmission rates remained steady during the study period. On multivariate analysis, female sex, age 45 years or older, esophagogastroduodenoscopy (EGD) during admission, and disposition to a short-term care facility or skilled nursing facility protected against readmissions. In contrast, coverage by Medicaid insurance, admission during a weekend, nonalcoholic cause of cirrhosis, and history of hepatic encephalopathy and ascites were associated with readmission. CONCLUSIONS: We found an exceptionally high 30-day readmission rate in patients with cirrhosis, although it remained stable during the study period. This study identified some modifiable factors such as disposition to a short-term care facility or skilled nursing facility and patients' attendance of alcohol rehabilitation facilities that could decrease the likelihood of readmission and could inform local and national healthcare policymakers.

Episodic, severe abdominal pain due to isolated jejunal Crohn's disease.

Small bowel Crohn's disease can present with episodic, relapsing, and remitting symptoms and delays in the diagnosis are common. We present a case of a young woman with three years of intermittent abdominal pain and nausea with negative previous evaluations. On presentation, inflammatory markers were elevated, and repeat imaging showed jejunal inflammation, with histopathological examination showing non-caseating granulomas of the small bowel consistent with Crohn's disease. This case highlights the importance of gastroenterologist recognizing the alarm signs in a patient with unexplained symptoms and adds to the literature on the clinical presentation of a rare diagnosis of isolated jejunal Crohn's disease.

Recurrence of Hepatocellular Carcinoma in Hepatitis C Virus (HCV) Liver Transplant Recipients Treated with Pretransplant Direct-Acting Antiviral (DAA) Therapy.

BACKGROUND: Direct-acting antivirals (DAAs) have revolutionized the treatment of hepatitis C virus (HCV). The impact of DAAs on recurrence of hepatocellular carcinoma (HCC) after liver transplantation (LT) remains uncertain. OBJECTIVE: We aimed to evaluate the risk of HCC recurrence in LT recipients cleared of HCV with DAAs at the time of LT compared to a control group of LT recipients who were viremic at the time of LT. METHODS: The study was a single-center, retrospective cohort study of patients undergoing LT for HCV-related HCC from 2002 to 2017. We compared time to post-LT HCC recurrence in patients with a sustained virological response (SVR) from DAAs prior to LT (DAA group) to patients who were viremic at LT (HCV+ group) using Kaplan-Meier analysis. We performed a secondary analysis comparing post-LT HCC recurrence in the DAA group to LT recipients with SVR from interferon-based treatment prior to LT (IFN group). RESULTS: One hundred fifty-one patients underwent LT for HCC related to HCV: 34 patients in DAA group, 95 patients in HCV+ group, and 22 in IFN group. Kaplan-Meier estimates of being HCC free were 96.2, 96.2, and 78.8% at 6, 12, and 24 months in DAA group, respectively, and 100, 98.6, and 95.8% at 6, 12, and 24 months in the HCV+ group, respectively; p = 0.08. There was no difference observed for HCC recurrence between the DAA and IFN groups. In a multivariate Cox proportional hazards model, DAA use increased the risk of post-LT HCC recurrence (HR 5.2, 95% CI 0.9-29.81, p = 0.07). CONCLUSIONS: A strong trend was observed on both Kaplan-Meier and multivariate analyses toward increased post-LT HCC recurrence in patients who achieved SVR prior to LT with DAAs compared to patients who were viremic at LT. Caution is required when considering pre-LT treatment of HCV with DAAs in patients with HCC.

Incidence and Risk Factors Associated With 30-Day Readmission for Alcoholic Hepatitis.

BACKGROUND: Alcohol abuse and liver disease are associated with high rates of 30-day hospital readmission, but factors linking alcoholic hepatitis (AH) to readmission are not well understood. We aimed to determine the incidence rate of 30-day readmission for patients with AH and to evaluate potential predictors of readmission. METHODS: We used the Nationwide Readmissions Database to determine the 30-day readmission rate for recurrent AH between 2010 and 2014 and examined trends in readmissions during the study period. We also identified the 20 most frequent reasons for readmission. Multivariate survey logistic regression analysis was used to identify factors associated with 30-day readmission. RESULTS: Of the 61,750 index admissions for AH, 23.9% were readmitted within 30-days. The rate of readmission did not change significantly during the study period. AH, alcoholic cirrhosis, and hepatic encephalopathy were the most frequent reasons for readmission. In multivariate analysis female sex, leaving against medical advice, higher Charlson comorbidity index, ascites, and history of bariatric surgery were associated with earlier readmissions, whereas older age, payer type (private or self-pay/other), and discharge to skilled nursing-facility reduced this risk. CONCLUSIONS: The 30-day readmission rate in patients with AH was high and stable during the study period. Factors associated with readmission may be helpful for development of consensus-based expert guidelines, treatment algorithms, and policy changes to help decrease readmission in AH.

Incidence, Admission Rates, and Predictors, and Economic Burden of Adult Emergency Visits for Acute Pancreatitis: Data From the National Emergency Department Sample, 2006 to 2012.

INTRODUCTION: Acute pancreatitis (AP) is the most common gastroenterology-related reason for hospital admission, and a major source of morbidity and mortality in the United States. This study examines the National Emergency Database Sample, a large national database, to analyze trends in emergency department (ED) utilization and costs, risk factors for hospital admission, and associated hospital costs and length of stay (LOS) in patients presenting with AP. METHODS: The National Emergency Database Sample (2006 to 2012) was evaluated for trends in ED visits, ED charges, hospitalization rates, hospital charges, and hospital LOS in patients with primary diagnosis of AP (further subcategorized by age and etiology). A survey logistic-regression model was used to determine factors predictive of hospitalization. RESULTS: A total of 2,193,830 ED visits were analyzed. There was a nonsignificant 5.5% (P=0.07) increase in incidence of ED visits for AP per 10,000 US adults from 2006 to 2012, largely driven by significant increases in ED visits for AP in the 18 to <45 age group (+9.2%; P=0.025), AP associated with alcohol (+15.9%; P=0.001), and AP associated with chronic pancreatitis (+59.5%; P=0.002). Visits for patients aged ≥65 decreased over the time period. Rates of admission and LOS decreased during the time period, while ED and inpatient costs increased (62.1%; P<0.001 and 7.9%; P=0.0011, respectively). Multiple factors were associated with increased risk of hospital admission from the ED, with the strongest predictors being morbid alcohol use [odds ratio (OR), 4.53; P<0.0001], advanced age (age>84 OR, 3.52; P<0.0001), and smoking (OR, 1.75; P<0.0001). CONCLUSIONS: Despite a relative stabilization in the overall incidence of ED visits for AP, continued increases in ED visits and associated costs appear to be driven by younger patients with alcohol-associated and acute on chronic pancreatitis. While rates of hospitalization and LOS are decreasing, associated inflation-adjusted costs are rising. In addition, identified risk factors for hospitalization, such as obesity, alcohol use, and increased age, should be explored in further study for potential use in predictive models and clinical improvement projects.

Incidence, Admission Rates, and Economic Burden of Adult Emergency Visits for Chronic Pancreatitis: Data From the National Emergency Department Sample, 2006 to 2012.

INTRODUCTION: Chronic pancreatitis (CP) is a common reason for emergency department (ED) visits, but little research has examined ED use by patients with CP. MATERIALS AND METHODS: The Nationwide Emergency Department Sample (2006 to 2012) was interrogated to evaluate trends in adult ED visits for a primary diagnosis of CP (International Classification of Disease, 9th revision, Clinical Modification code: 577.1), the rates of subsequent hospital admission, and total charges. A survey logistic regression model was used to determine factors associated with hospitalization from the ED. RESULTS: We identified 253,753 ED visits with a primary diagnosis of CP. No significant trends in annual incidence were noted. However, the ED-to-hospitalization rates decreased by 3% per year (P<0.001) and mean ED charges after adjusting for inflation increased by 11.8% per year (P<0.001). Higher Charlson comorbidity index, current smoker status, alcohol use, and biliary-related CP were associated with hospitalization. In hospitalized patients, length of stay decreased by 2.2% per year (P=0.003) and inpatient charges increased by 2.9% per year (P=0.004). CONCLUSIONS: Patient characteristics associated with higher risk of hospitalization from the ED deserve further attention.

Sorafenib for Treatment of Hepatocellular Carcinoma: A Survival Analysis From the South American Liver Research Network.

GOALS: We aim to describe the efficacy, safety profile, and variables associated with survival in patients with hepatocellular carcinoma (HCC) treated with sorafenib in South America. BACKGROUND: Sorafenib has been shown to improve survival in patients with advanced HCC. There are few data on sorafenib use for HCC in South America. STUDY: We performed a retrospective analysis of HCC cases treated with sorafenib from 8 medical centers in 5 South American countries, between January 2010 and June 2017. The primary endpoint was overall survival (OS), which was defined as time from sorafenib initiation to death or last follow-up. Risk factors for decreased OS were assessed using Cox proportional hazard regression and log-rank tests. RESULTS: Of 1336 evaluated patients, 127 were treated with sorafenib and were included in the study. The median age of individuals was 65 years (interquartile range, 55 to 71) and 70% were male individuals. Median OS in all patients was 8 months (interquartile range, 2 to 17). Variables associated with survival on multivariate analysis were platelets >/<250,000 mm (2 vs. 8 mo, P=0.01) and Barcelona Clinic Liver Cancer (BCLC) stage (A/B, 13 vs. C/D, 6 mo; P=0.04). In a subanalysis of patients with BCLC stage C, platelets >/<250,000 mm were also independently associated with survival (2 vs. 5.5 mo, P=0.03). Patients lived longer if they experienced any side effects from sorafenib use (11 vs. 2 mo, P=0.009). Patients who stopped sorafenib because of side effects had shorter survival compared with patients who were able to tolerate side effects and continue treatment (7.5 vs. 13 mo, P=0.01). CONCLUSIONS: Pretreatment elevation of platelets and advanced BCLC stage were independently associated with poor survival on sorafenib in a South American cohort.

Incidence and Predictors of 30-Day Readmission Among Patients Hospitalized for Chronic Pancreatitis.

OBJECTIVES: Chronic pancreatitis (CP) hospitalizations along with associated morbidity and costs are increasing. The goal of this study was to use the National Readmission Database to identify the incidence and risk factors for 30-day readmissions among patients with CP. METHODS: We performed a retrospective analysis of National Readmission Database from January 2013 to December 2013 to determine patient demographic and clinical characteristics predictive of 30-day hospital readmission for adult patients (aged >18 years) discharged with a principle diagnosis of CP. A survey logistic regression model was used to determine the predictive value of selected variables for 30-day readmission. RESULTS: In 2013, 12,545 admissions with primary diagnosis of CP were noted, and 30.4% were readmitted within 30 days. Cholecystectomy (odds ratio [OR], 0.53; P = 0.0024) or endoscopic retrograde cholangiopancreatography (OR, 0.70; P = 0.01) during index admission was associated with decreased all-cause readmissions. Pancreatectomy during index admission was associated with reduced (OR, 0.2; P = 0.0005) pancreatitis-related readmissions. CONCLUSIONS: Hospital readmissions for CP are frequent and pose a significant healthcare burden. Performing cholecystectomy, endoscopic retrograde cholangiopancreatography, or pancreatectomy during index admission was associated with reduced odds of readmission.

Role of dexmedetomidine in early extubation of the intensive care unit patients.

BACKGROUND AND AIMS: Patients on ventilatory support in intensive care unit (ICU) require sedation and analgesia to facilitate mechanical ventilation and endotracheal tube tolerance. The selection of the agent should be such that it does not interfere with the early extubation of the patients. We compared the efficacy of dexmedetomidine with midazolam to facilitate extubation of patients from mechanical ventilation in terms of the sedative properties, cardiovascular responses, ventilation, and extubation characteristics and safety profile. MATERIALS AND METHODS: A total of 40 adult, mechanically ventilated patients of either sex, aged 18-60 years, meeting the standard criteria for weaning, randomized into 2 groups of 20 patients each, received intravenous infusion of dexmedetomidine (0.2-0.7 mcg/kg/h) or midazolam (0.04-0.2 mg/kg/h) as needed for Ramsay sedation scale 2-4. Extubation following standard extubation protocol was done. Time for extubation and vital parameters were regularly recorded. RESULTS: The time to extubation in the dexmedetomidine group was significantly lower than in the midazolam group. Heart rate and blood pressure was significantly lower in dexmedetomidine group than the midazolam group at most of the times. CONCLUSIONS: Dexmedetomidine has clinically relevant benefits compared with midazolam in facilitating extubation due to its shorter time to extubation, more hemodynamic stability, easy arousability, and lack of respiratory depression.
