RESUMO

Increased alcohol consumption during the coronavirus disease 2019 pandemic is projected to impact alcohol-related liver disease (ALD) morbidity and mortality. Inter-hospital escalation-of-care referral requests to our tertiary-care hepatology unit were analyzed from January 2020 through December 2022. Most requests to our center were for ALD with an increase in requests from intermediate care units, suggestive of higher acuity illness.

RESUMO

BACKGROUND & AIMS: Twenty-five percent of the United States population is enrolled in Medicaid. Rates of Crohn's disease (CD) have not been estimated in the Medicaid population since the Affordable Care Act expansion in 2014. We aimed to estimate the incidence and prevalence of CD by age, sex, and race. METHODS: We identified all 2010-2019 Medicaid CD encounters using codes from the International Classification of Diseases, Clinical Modification versions 9 and 10. Individuals with ≥2 CD encounters were included. Sensitivity analyses were performed on other definitions (eg, ≥1 CD encounter). Incidence required ≥1 year of Medicaid eligibility prior to first CD encounter date (2013-2019). We calculated CD prevalence and incidence using the entire Medicaid population as the denominator. Rates were stratified by calendar year, age, sex, and race. Poisson regression models examined CD-associated demographic characteristics. We compared demographics and treatments of the entire Medicaid population with the multiple CD case definitions using percent and median. RESULTS: A total of 197,553 beneficiaries had ≥2 CD encounters. The CD point prevalence per 100,000 persons rose from 56 (2010) to 88 (2011) to 165 (2019). CD incidence per 100,000 person-years was 18 (2013) and 13 (2019). Higher incidence and prevalence rates correlated with female, white, or multiracial beneficiaries. Prevalence rates rose in later years. Incidence decreased over time. CONCLUSIONS: From 2010 to 2019, Medicaid population CD prevalence increased while incidence decreased from 2013 to 2019. Overall Medicaid CD incidence and prevalence ranges align with prior large administrative database studies.

RESUMO

Transplant centers conventionally require at least 6 months of alcohol abstinence before offering liver transplants for alcohol-associated liver disease. However, early liver transplant (ELT)-proceeding with a transplant when clinically necessary without first meeting the conventional requirement-is increasingly gaining attention. In our study, we qualitatively assessed ELT recipients' perceived challenges and supports regarding alcohol-associated liver disease, transplant, and posttransplant survivorship. To diversify perspectives based on gender, race/ethnicity, age, time since ELT, and pretransplant abstinence duration, we purposively recruited ELT recipients and conducted semistructured interviews. Recruitment continued until data saturation. We analyzed transcripts using inductive thematic analysis. We interviewed 20 ELT recipients between June and December 2020 and identified themes within 3 participant-characterized time periods. Three themes emerged in life before severe illness: (1) alcohol as a "constant" part of life, (2) alcohol use negatively affecting relationships and work life, and (3) feeling "stuck" in the cycle of drinking. Two themes emerged during the severe illness period: (4) rapidity of health decline and (5) navigating medical care and the 6-month abstinence requirement. Finally, in life after transplant, 4 themes emerged: (6) feelings of shame or stigma and new self-worth, (7) reconnecting with others and redefining boundaries, (8) transplant as a defining point for sobriety, and (9) work-related challenges. Overall, participants expressed gratitude for receiving a gift of life and acknowledged their responsibilities to the new liver. ELT recipient experiences reveal complex psychosocial challenges related to addiction, inadequate support system, and stigma, particularly in the posttransplant period. The care of ELT recipients would be incomplete if focused solely on optimizing patient or graft survival.

RESUMO

OBJECTIVES: The impact of race on patients presenting to North American hospitals with postliver transplant complications/failure (PLTCF) has not been studied fully. We compared in-hospital mortality and resource utilization outcomes between White and Black patients hospitalized with PLTCF. METHODS: This was a retrospective cohort study that evaluated the years 2016 and 2017 from the National Inpatient Sample. Regression analysis was used to determine in-hospital mortality and resource utilization. RESULTS: There were 10,805 hospitalizations for adults with liver transplants who presented with PLTCF. White and Black patients with PLTCF made up 7925 (73.3%) hospitalizations from this population. Among this group, 6480 were White (81.7%) and 1445 were Black (18.2%). Blacks were younger than Whites (mean age ± standard error of the mean: 46.8 ± 1.1 vs 53.6 ± 0.39 years, P < 0.01). Blacks were more likely to be female (53.9% vs 37.4%, P < 0.01). Charlson Comorbidity Index scores were not significantly different (scores ≥3: 46.7% vs 44.2%, P = 0.83). Blacks had significantly higher odds for in-hospital mortality (adjusted odds ratio 2.9, confidence interval [CI] 1.4-6.1; P < 0.01). Hospital charges were higher for Blacks compared with Whites (adjusted mean difference $48,432; 95% CI $2708-$94,157, P = 0.03). Blacks had significantly longer lengths of hospital stays (adjusted mean difference 3.1 days, 95% CI 1.1-5.1, P < 0.01). CONCLUSIONS: Compared with White patients hospitalized for PLTCF, Black patients had higher in-hospital mortality and resource use. Investigation into causes leading to this health disparity is needed to improve in-hospital outcomes.

RESUMO

Alcohol sales and consumption have increased during the coronavirus disease 2019 pandemic, but their downstream effects on alcohol-related liver disease (ALD) are unclear. We analyzed inter-hospital escalation-of-care referrals to our tertiary care inpatient liver unit across 18 months through December 2020. There was a significant rise in severe ALD with recent unhealthy drinking in our regional community during the pandemic.

RESUMO

BACKGROUND: Limited prior data suggest that preexisting liver disease is associated with adverse outcomes among patients with coronavirus disease 2019 (COVID-19). Fibrosis-4 (FIB-4) is a noninvasive index of readily available laboratory measurements that represents hepatic fibrosis. We evaluated the association between FIB-4 at the early stage of infection and COVID-19 outcomes. METHODS: FIB-4 was evaluated at admission in a cohort of 267 patients admitted with early-stage COVID-19 confirmed through reverse-transcription polymerase chain reaction assay. Hazard of ventilator use and of high-flow oxygen was estimated using Cox regression models controlled for covariates. Risks of progression to severe disease and of death/prolonged hospitalization were estimated using multivariable logistic regression models. RESULTS: Forty-one (15%) patients progressed to severe disease, 36 (14%) required high-flow oxygen support, 10 (4%) required mechanical ventilator support, and 1 died. FIB-4 between 1.45 and 3.25 was associated with a greater than 5-fold (95% confidence interval [CI], 1.2-28) increased hazard of high-flow oxygen use, a greater than 4-fold (95% CI, 1.5-14.6) increased odds of progression to severe disease, and an over 3-fold (95% CI, 1.4-7.7) increased odds of death or prolonged hospitalization. FIB-4 >3.25 was associated with a greater than 12-fold (95% CI, 2.3-68. 7) increased hazard of high-flow oxygen use and an over 11-fold (95% CI, 3.1-45) increased risk of progression to severe disease. All associations were independent of sex, number of comorbidities, and inflammatory markers (D-dimer, C-reactive protein). CONCLUSIONS: FIB-4 at the early-stage of COVID-19 had an independent and dose-dependent association with adverse outcomes during hospitalization. FIB-4 provided significant prognostic value for estimating adverse outcomes among COVID-19 patients.

RESUMO

BACKGROUND & AIMS: While abstinence-promoting behavioral and pharmacotherapies are part of the therapeutic foundation for alcohol use disorder (AUD) and alcohol-associated liver disease (ALD), these therapies, along with alcohol screening and education, are often underutilized. Our aim was to examine provider attitudes and practices for alcohol screening, treatment and education in patients with liver disease. METHODS: We conducted a survey of primarily (89%) hepatology and gastroenterology providers within (80%) and outside the United States (20%). Surveys were sent to 921 providers with 408 complete responses (44%), of whom 343 (80%) work in a tertiary liver transplant center. RESULTS: While alcohol screening rates in liver disease patients was nearly universal, less than half of providers reported practicing with integrated addiction providers, using alcohol biomarkers and screening tools. Safe alcohol use by liver disease patients was felt to exist by 40% of providers. While 60% of providers reported referring AUD patients for behavioral therapy, 71% never prescribed AUD pharmacotherapy due to low comfort (84%). Most providers (77%) reported low addiction education and 90% desired more during GI/hepatology fellowship training. Amongst prescribers, baclofen was preferred, but with gaps in pharmacotherapy knowledge. Overall, there was low adherence to the 2019 AASLD practice guidance for ALD, although higher in hepatologists and experienced providers. CONCLUSIONS: While our survey of hepatology and gastroenterology providers demonstrated higher rates of alcohol screening and referrals for behavioral therapy, we found low rates of prescribing AUD pharmacotherapy due to knowledge gaps from insufficient education. Further studies are needed to assess interventions to improve provider alignment with best practices for treating patients with AUD and ALD.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic has brought challenges to clinicians caring for patients with chronic liver disease. In the past 6 months, COVID-19 has led to over 150,000 deaths in the United States and over 660,000 deaths around the world. Mounting evidence suggests that chronic liver diseases can have an adverse effect on the clinical outcomes of patients with COVID-19. We present a comprehensive review of the latest literature on preexisting liver diseases and its interrelationship with COVID-19 infection in cirrhosis, hepatocellular carcinoma, nonalcoholic fatty liver disease, autoimmune hepatitis, and viral hepatitis B. As social distancing and telemedicine gain new footing, we synthesize recommendations from 3 major hepatology societies [American Association for the Study of Liver Disease (AASLD), the European Association for the Study of Liver (EASL), and the Asian Pacific Association for the Study of Liver (APASL)] to present the best approaches for caring for patients with liver diseases as well as those requiring liver transplantation.

RESUMO

The novel coronavirus disease 2019 (COVID-19) is a highly infectious and rapidly spreading disease. There are limited published data on the epidemiology and outcomes of COVID-19 infection among organ transplant recipients. After initial flulike symptoms, progression to an inflammatory phase may occur, characterized by cytokine release rapidly leading to respiratory and multiorgan failure. We report the clinical course and management of a liver transplant recipient on hemodialysis, who presented with COVID-19 pneumonia, and despite completing a 5-day course of hydroxychloroquine, later developed marked inflammatory manifestations with rapid improvement after administration of off-label, single-dose tocilizumab. We also highlight the role of lung ultrasonography in early diagnosis of the inflammatory phase of COVID-19. Future investigation of the effects of immunomodulators among transplant recipients with COVID-19 infection will be important.

RESUMO

Early liver transplant (LT) for alcohol-associated disease (i.e., without a specific sobriety period) is controversial but increasingly used. Using the multicenter American Consortium of Early Liver Transplantation for Alcoholic Hepatitis (ACCELERATE-AH) cohort, we aimed to develop a predictive tool to identify patients pretransplant with low risk for sustained alcohol use posttransplant to inform selection of candidates for early LT. We included consecutive ACCELERATE-AH LT recipients between 2012 and 2017. All had clinically diagnosed severe alcoholic hepatitis (AH), no prior diagnosis of liver disease or AH, and underwent LT without a specific sobriety period. Logistic and Cox regression, classification and regression trees (CARTs), and least absolute shrinkage and selection operator (LASSO) regression were used to identify variables associated with sustained alcohol use post-LT. Among 134 LT recipients for AH with median period of alcohol abstinence pre-LT of 54 days, 74% were abstinent, 16% had slips only, and 10% had sustained alcohol use after a median 1.6 (interquartile range [IQR]: 0.7-2.8) years follow-up post-LT. Four variables were associated with sustained use of alcohol post-LT, forming the Sustained Alcohol Use Post-LT (SALT) score (range: 0-11): >10 drinks per day at initial hospitalization (+4 points), multiple prior rehabilitation attempts (+4 points), prior alcohol-related legal issues (+2 points), and prior illicit substance abuse (+1 point). The C statistic was 0.76 (95% confidence interval [CI]: 0.68-0.83). A SALT score ≥5 had a 25% positive predictive value (95% CI: 10%-47%) and a SALT score of <5 had a 95% negative predictive value (95% CI: 89%-98%) for sustained alcohol use post-LT. In internal cross-validation, the average C statistic was 0.74. Conclusion: A prognostic score, the SALT score, using four objective pretransplant variables identifies candidates with AH for early LT who are at low risk for sustained alcohol use posttransplant. This tool may assist in the selection of patients with AH for early LT or in guiding risk-based interventions post-LT.

RESUMO

GOALS AND BACKGROUND: There are limited data on post-liver transplantation (LT) outcomes of patients with sarcoidosis. STUDY: We examined the clinical characteristics and post-LT outcomes of patients with sarcoidosis using the United Network for Organ Sharing database from 1985 to 2016 and compared them to patients (entire cohort as well as age, gender, and year of LT-matched counterparts) with primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC). For the matched design, a conditional logistic regression was used for categorical variables and marginal generalized estimating equation regression models for continuous variables. Survival functions were constructed using the Kaplan-Meier estimator. RESULTS: A total of 206 patients with sarcoidosis, transplanted during the study period, were compared with 3933 patients with PBC and 5323 with PSC. In total, 197 patients with sarcoidosis were compared with 576 with PBC and 576 with PSC in the 1:3 matched analysis. The sarcoidosis group had a higher proportion of blacks (53.3%) and a higher prevalence of obesity and type II diabetes mellitus. The graft and patient survival for sarcoidosis patients were lower when compared with unmatched PBC and PSC patients. The results remained unchanged in the matched analysis. At 5-year, patient survival was ~15% lower for the sarcoidosis group when compared with PBC and PSC. In multivariate analysis using matched data, hazard ratios (HRs) for graft (HR=1.68, 95% confidence interval=1.03-2.75, P=0.04), and patient (HR=2.01, confidence interval=1.22-3.34, P<0.01) survival were higher for sarcoidosis. CONCLUSIONS: Patients who underwent LT for sarcoidosis had a lower graft and patient survival when compared with those with PBC or PSC. That being said, 66% of patients survived 5 years after transplantation, suggesting that LT is an acceptable option in this population.

RESUMO

BACKGROUND: The opioid crisis has led to an increase in hepatitis C virus-positive donors in the past decade. Whereas historically hepatitis C seropositive organs were routinely discarded, the advent of direct-acting antiviral agents has notably expanded the utilization of organs from donors with hepatitis C. There has been growing experience with liver transplantation (LT) from hepatitis C seropositive donors to hepatitis C seropositive recipients. However, data remain limited on LT from hepatitis C seropositive or hepatitis C ribonucleic acid positive donors to hepatitis C seronegative recipients. METHODS: We performed a retrospective study of 26 hepatitis C seronegative recipients who received hepatitis C seropositive donor livers followed by preemptive antiviral therapy with direct-acting antiviral treatment at the Johns Hopkins Hospital Comprehensive Transplant Center from January 1, 2017, to August 31, 2019. RESULTS: Twenty-five of the 26 recipients are alive with proper graft function; 20 of them received livers from hepatitis C nucleic acid testing positive donors. All 12 recipients who completed their direct-acting antiviral courses and have reached sufficient follow-up for sustained virologic response have achieved sustained virologic response. Nine of our recipients have either completed direct-acting antiviral treatment without sufficient follow-up time for sustained virologic response or are undergoing direct-acting antiviral treatment. One patient is awaiting antiviral treatment initiation pending insurance approval. Of note, 11 of 12 patients with sustained virologic response received a hepatitis C nucleic acid testing positive donor liver. CONCLUSION: Hepatitis C seronegative patients who receive a hepatitis C seropositive or hepatitis C nucleic acid testing positive liver allograft can enjoy good short-term outcomes with hepatitis C cure following direct-acting antiviral treatment.

RESUMO

Acute alcoholic hepatitis is a syndrome of jaundice and hepatic decompensation that occurs with excessive alcohol consumption. The diagnosis can be made with a combination of clinical characteristics and laboratory studies, though biopsy may be required in unclear cases. Acute alcoholic hepatitis can range from mild to severe disease, as determined by a Maddrey discriminant function ≥32. Mild forms can be managed with supportive care and abstinence from alcohol. While mild form has an overall good prognosis, severe alcoholic hepatitis is associated with an extremely high short-term mortality of up to 50%. Additional complications of severe alcoholic hepatitis can include hepatic encephalopathy, gastrointestinal bleeding, renal failure, and infection; these patients frequently require intensive care unit admission. Corticosteroids may have short-term benefit in this group of patients if there are no contraindications; however, a subset of patients do not respond to steroids. New emerging therapies, which target hepatic regeneration, bile acid metabolism, and extracorporeal liver support, are being investigated. Liver transplantation for alcoholic liver disease was traditionally only considered in patients who have achieved 6 months of abstinence, in part due to social and ethical concerns regarding the use of a limited resource. However, the majority of patients with severe alcoholic hepatitis who fail medical therapy will not live long enough to meet this requirement. Recent studies have demonstrated that early liver transplantation in carefully selected patients with severe alcoholic hepatitis who fail medical therapy can provide a significant survival benefit and yields survival outcomes comparable to liver transplantation for other indications, with 6-month survival rates ranging from 77% to 100%. Alcohol relapse posttransplantation remains an important challenge, and heavy consumption can contribute to graft loss and mortality. Future investigation should address the substantial post-liver transplantation recidivism rate, from improving selection criteria to increasing posttransplantation substance abuse treatment resources.

RESUMO

Mangroves are recognized as one of the richest carbon storage systems. However, the factors regulating carbon sinks in mangrove ecosystems are still unclear, particularly in the subtropical mangroves. The biomass, production, litterfall, detrital export and decomposition of the dominant mangrove vegetation in subtropical (Kandelia obovata) and tropical (Avicennia marina) Taiwan were quantified from October 2011 to July 2014 to construct the carbon budgets. Despite the different tree species, a principal component analysis revealed the site or environmental conditions had a greater influence than the tree species on the carbon processes. For both species, the net production (NP) rates ranged from 10.86 to 27.64 Mg C ha-1  year-1 and were higher than the global average rate due to the high tree density. While most of the litterfall remained on the ground, a high percentage (72%-91%) of the ground litter decomposed within 1 year and fluxed out of the mangroves. However, human activities might cause a carbon flux into the mangroves and a lower NP rate. The rates of the organic carbon export and soil heterotrophic respiration were greater than the global mean values and those at other locations. Only a small percentage (3%-12%) of the NP was stored in the sediment. The carbon burial rates were much lower than the global average rate due to their faster decomposition, indicating that decomposition played a critical role in determining the burial rate in the sediment. The summation of the organic and inorganic carbon fluxes and soil heterotrophic respiration well exceeded the amount of litter decomposition, indicating an additional source of organic carbon that was unaccounted for by decomposition in the sediment. Sediment-stable isotope analyses further suggest that the trapping of organic matter from upstream rivers or adjacent waters contributed more to the mangrove carbon sinks than the actual production of the mangrove trees.

RESUMO

BACKGROUND AND AIM: Spontaneous bacterial peritonitis (SBP) is a serious complication of cirrhosis and is associated with significant morbidity and mortality. In this study, we examined the clinical characteristics and risk factors associated with mortality in hospitalized patients presenting with SBP. METHODS: The Nationwide Inpatient Sample was queried for all hospitalizations involving SBP from 2006 to 2014 using the International Classification of Disease-9-CM Code. Logistic regression was performed to evaluate the association between SBP mortality and factors such as age, gender, race/ethnicity, and concomitant medical conditions at presentation (e.g., variceal hemorrhage, hepatic encephalopathy, acute renal failure, coagulopathy, and other infections including pneumonia). The lengths of stay (LOS) and total charges were also examined. RESULTS: From 2006 to 2014, there were 88,167 SBP hospitalizations with 29,963 deaths (17.6% in-hospital mortality). The mean age of patients who died in the hospital was higher (58.2 years vs. 55.8, p < 0.01) than those who survived the admission. Acute alcoholic hepatitis was noted among a higher proportion of patients who died (7.0 vs. 5.9%, p < 0.01), who were also likely to have more medical comorbidities. In multivariable analysis, older age, female gender, hepatic encephalopathy, coagulopathy, variceal hemorrhage, sepsis, pneumonia, and acute kidney injury were associated with increased in-hospital mortality. This group also had longer LOS (11.6 days vs. 9.1, p < 0.01) and higher total charges ($138,273 vs. $73,533, p < 0.01). CONCLUSION: SBP is associated with significant in-hospital mortality, especially in patients with concurrent risk factors. SBP remains a significant burden to the healthcare system.

RESUMO

Risk and Prognosis of Acute Liver Injury Among Hospitalized Patients with Hemodynamic Instability: A Nationwide Analysis Introduction and aim. Critically ill patients in states of circulatory failure are at risk of acute liver injury, from mild elevations in aminotransferases to substantial rises consistent with hypoxic hepatitis or "shock liver". The present study aims to quantify the national prevalence of acute liver injury in patients with hemodynamic instability, identify risk factors for its development, and determine predictors of mortality. MATERIAL AND METHODS: The 2009-2010 Nationwide Inpatient Sample was interrogated using ICD-9-CM codes for hospital admissions involving states of hemodynamic lability. Multivariable logistic regression was used to evaluate the risks of acute liver injury and death in patients with baseline liver disease, congestive heart failure, malnutrition, and HIV. RESULTS: Of the 2,865,446 patients identified in shock, 4.60% were found to have acute liver injury. A significantly greater proportion of patients with underlying liver disease experienced acute liver injury (22.03%) and death (28.47%) as compared to those without liver disease (3.18% and 18.82%, respectively). The odds of developing acute liver injury were increased in all baseline liver diseases studied, including all-cause cirrhosis, hepatitis B, hepatitis C, alcoholic liver disease, and non-alcoholic fatty liver disease, as well as in congestive heart failure and malnutrition. All-cause cirrhosis and alcoholic liver disease, however, conferred the greatest risk. Similar trends were seen with mortality. HIV was not a predictor for acute liver injury. CONCLUSION: Liver injury is a major concern among patients with protracted circulatory instability, especially those suffering from underlying liver disease, heart failure, or malnutrition.

RESUMO

OBJECTIVE: To examine our pilot to transplant selected patients with acute alcoholic hepatitis, initiated in October 2012. BACKGROUND: Six months of alcohol abstinence is typically required before liver transplant. A Franco-Belgian protocol showed that early transplant in severe alcoholic hepatitis could improve survival with low incidence of alcohol relapse. Application of this controversial indication is growing despite unclear generalizability. METHODS: Data was collected on all patients with alcohol-related liver disease since initiation of the pilot through June 2015. Patients were stratified into two groups: severe alcoholic hepatitis as first liver decompensation (Group 1), alcoholic cirrhosis with ≥6 months abstinence (Group 2). Alcohol relapse was defined as any evidence of alcohol consumption after transplant, which was assessed for harmful patterns of binge or frequent drinking. RESULTS: Forty-three patients underwent liver transplant, including 17 patients in Group 1. Six-month survival was 100% versus 89% for Groups 1 and 2, respectively (P = 0.27). Alcohol relapse was similar in Group 1 versus Group 2: 23.5% versus 29.2% (P > 0.99). Harmful drinking was higher in Group 1 versus Group 2, despite lack of statistical significance: 23.5% versus 11.5% (P = 0.42). CONCLUSIONS: In this pilot with carefully selected patients, early liver transplant provided excellent short-term survival, and similar rates of alcohol relapse compared with patients with 6 months of abstinence. Harmful patterns of relapse remain challenging in this population, highlighting the need for validated models to predict alcohol relapse, and need for extreme caution in selecting patients for this exceptional indication. Larger prospective studies and longer follow up are necessary.

RESUMO

BACKGROUND & AIMS: Little is known about the effects of biologic agents used to treat Crohn's disease (CD) on its long-term complications, such as short bowel syndrome and intestinal failure (SBS-IF). We evaluated trends in small bowel resections and health care utilization among patients with CD with and without SBS-IF. METHODS: We collected data on the National Inpatient Sample on 2,989,185 patients hospitalized with CD in the United States before the time period in which CD was treated with biologic agents (1993-1997) and after biologic therapy became widespread (1998-2014). We used Poisson and linear regression analyses to evaluate trends for small bowel resections and health care utilization among patients with CD with and without SBS-IF. Multivariable models were adjusted for age, sex, Charlson-Deyo comorbidity index, payer source, hospital size, region, and teaching status. RESULTS: The proportions of patients who underwent resection did not significantly change during the period before biologic therapy (121.8 per 1000 hospitalizations in 1993 to 110.1 per 1000 hospitalizations in 1997; P trend =.14) but decreased significantly during the period after biologic therapy began (99.0 per 1000 hospitalizations in 1998 to 64.6 per 1000 hospitalizations in 2014; P trend < .01). However, among patients with SBS-IF, similar proportions of patients underwent resection during the period before biologic therapy (0.7 per 1000 hospitalizations in 1993 to 0.7 per 1000 hospitalizations in 1997; P trend = .92) and during the period after biologic therapy (0.6 per 1000 hospitalizations in 1998 to 0.7 per 1000 hospitalizations in 2014; P trend = .06). Rates of hospitalization for patients with SBS-IF increased from 16.5 per 1000 hospitalizations in 1998 to 19.5 per 1000 hospitalizations in 2014 (P trend < .01). SBS-IF hospitalizations were associated with longer lengths of stay (P < .01) and greater total charges (P < .01). CONCLUSIONS: In a study of the United States population, we found that the use of biologic agents to treat CD reduced the proportion of patients undergoing resection, but not among patients with SBS-IF. These findings indicate that biologic agents reduce some but not all features of CD. Studies are needed to identify patients at risk for SBS-IF, prevent and treat this complication, and identify new treatments.
