RESUMO
Doxycycline (DOX) is a tetracycline antibiotic that is prescribed for treating a variety of infections involving the skin, respiratory tract, and urogenital system. Adversely, esophageal mucosal injury due to DOX is well described; however, gastric mucosal injury is less commonly reported and may result in severe gastrointestinal hemorrhage and occasionally, perforation. In most reported cases of DOX-induced gastric lesions, patients are symptomatic upon presentation leading to endoscopic evaluation and diagnosis with biopsy. However, severe gastric insults may go unrecognized in rare cases of asymptomatic patients, increasing the risk of mortality.

New-onset heart failure is a frequent complication after orthotopic liver transplantation (OLT). Left atrial enlargement (LAE) may be a sign of occult left heart disease. Our primary objective was to determine invasive hemodynamic and clinical predictors of LAE and then investigate its effect on post-transplant outcomes. Of 609 subjects who received OLT between January 1, 2010, and October 1, 2018, 145 who underwent preoperative right-sided cardiac catheterization and transthoracic echocardiography were included. Seventy-eight subjects (54%) had pretransplant LAE. Those with LAE had significantly lower systemic vascular resistance with higher cardiac and stroke volume index (61.0 vs 51.7 ml/m2; p <0.001), but there was no difference in pulmonary artery wedge pressure. There was a linear relation between left atrial volume index and stroke volume index (R2 = 0.490, p<0.001), but not pulmonary artery wedge pressure. The presence of severe LAE was associated with a reduced likelihood (hazard ratio = 0.26, p = 0.033) of reaching the composite end point of new-onset systolic heart failure, heart failure hospitalization, or heart failure death within 12 months post-transplant. There was also a significant reduction in LAE after transplantation (p = 0.013). In conclusion, LAE was common in OLT recipients and was more closely associated with stroke volume than left heart filling pressures. The presence of LAE was associated with a reduced likelihood of reaching composite outcomes and tended to regress after transplant.

Idiopathic adulthood ductopenia (IAD) is a chronic small duct cholestatic biliary disease that is characterized by the loss of interlobular bile ducts. It is diagnosed when there is biochemical evidence of cholestatic liver disease, ductopenia on liver biopsy, and no other identifiable cause of cholestasis. We present a patient with 10 days of progressive abdominal pain, jaundice, and worsening liver function tests who advanced to fulminant liver failure with no apparent underlying cause. He was found to have cirrhosis, with biopsy demonstrative of ductopenia, consistent with idiopathic adulthood ductopenia, which is a rare etiology of cirrhosis but should be considered when the typical workup yields no answer.
RESUMO
Esophagitis dissecans superficialis is a rare clinical endoscopic finding with poorly understood pathogenesis and ill-defined management. A 71-year-old man is admitted with progressively worsening dysphagia and odynophagia with endoscopic features most consistent with severe esophagitis dissecans superficialis. Extensive workup did not reveal an etiology, and he was subsequently treated with steroids, resulting in rapid, almost complete clinical and endoscopic recovery.

BACKGROUND & AIMS: Treatment options are limited for patients with hepatitis C (HCV) infection with treatment failure after sofosbuvir plus an NS5A inhibitor. There are some data for the efficacy of glecaprevir/pibrentasvir (G/P) in these patients. We performed a randomized trial of the safety and efficacy of 12 and 16 weeks of G/P, with or without ribavirin, in patients with HCV genotype 1 infection with treatment failure after sofosbuvir and an NS5A inhibitor. METHODS: We performed a phase 3b, open-label study of patients with chronic HCV genotype 1 infection who received previous treatment with sofosbuvir plus an NS5A inhibitor. Patients without cirrhosis were randomly assigned to groups that received G/P for 12 weeks (n = 78, group A) or 16 weeks (n = 49, group B). Patients with compensated cirrhosis were randomly assigned to groups that received G/P and ribavirin for 12 weeks (n = 21, group C) or G/P for 16 weeks (n = 29, group D). The primary end point was a sustained virologic response 12 weeks after treatment. Samples collected at baseline and at time of treatment failure were sequenced for resistance-associated substitutions in NS3 and NS5A. RESULTS: Of the 177 patients in the 4 groups, 81% were men, 79% had HCV genotype 1a infection, and 44% were black. Proportions of patients with sustained virologic response 12 weeks after treatment in groups A, B, C, and D were 90%, 94%, 86%, and 97%, respectively. The treatment failed in 13 (7.3%) patients with HCV genotype 1a infection, 6 (7.9%) in group A, 3 (6.1%) in group B, 3 (6.1%) in group C (6.1%), and 1 (3.4%) in group D. Most patients had baseline resistance-associated substitutions in NS5A. Treatment-emergent resistance-associated substitutions in NS3 and NS5A were observed in 9 and 10 patients with treatment failure, respectively. G/P was well tolerated. Ribavirin increased adverse events but did not increase efficacy. CONCLUSIONS: In a randomized study of patients with chronic HCV genotype 1 infection who received previous treatment with sofosbuvir plus an NS5A inhibitor, 16 weeks treatment with G/P produced sustained virologic response 12 weeks after treatment in >90% of patients, including those with compensated cirrhosis.

BACKGROUND: Blood phosphatidylethanol (PEth) is a promising biomarker of alcohol consumption. This study was conducted to evaluate its performance in patients with liver disease. METHODS: This study included 222 patients with liver disease. Patient-reported alcohol use was obtained as a reference standard, and PEth was measured by tandem mass spectrometry. Receiver operating characteristic (ROC) and contingency table analyses were used to assess the performance of PEth in detecting any drinking and averaging 4 or more drinks daily in the past 30 days. RESULTS: At the limit of quantitation (20 ng/ml), PEth was 73% sensitive (95% confidence interval [CI] 65 to 80) and 96% specific (95% CI 92 to 100) for any drinking in the past month. Subjects who drank but had a negative PEth result were mainly light drinkers. Subjects who reported 30-day abstinence but with quantifiable PEth either reported heavy drinking within the past 6 weeks or had data that suggested underreported drinking. At the optimal cutoff concentration of 80 ng/ml, PEth was 91% sensitive (95% CI 82 to 100) and 77% specific (95% CI 70 to 83) for averaging at least 4 drinks daily. CONCLUSIONS: PEth is a useful test for detecting alcohol use in patients with liver disease, but cutoff concentrations for heavy drinking will result in misclassification of some moderate to heavy drinkers.

BACKGROUND: It is important to monitor alcohol use in the care of patients with liver disease, but patient self-report can be unreliable. We therefore evaluated the performance of urine ethyl glucuronide (EtG) and ethyl sulfate (EtS) in detecting alcohol use in the days preceding a clinical encounter. METHODS: Subjects (n = 120) were recruited at a university-based hepatology clinic or during hospitalization. Alcohol consumption was ascertained by validated self-report measures. Urine EtG (cutoff 100 ng/ml) and EtS (cutoff 25 ng/ml) concentrations were assayed by a contracted laboratory using tandem mass spectrometry. The sensitivity and specificity of each biomarker in the detection of drinking during the 3 and 7 days preceding the clinic visit were determined, as well as the influence of liver disease severity on these results. RESULTS: Urine EtG (sensitivity 76%, specificity 93%) and urine EtS (sensitivity 82%, specificity 86%) performed well in identifying recent drinking, and liver disease severity does not affect biomarker performance. After elimination of 1 false-negative self-report, urine EtG > 100 ng/ml was 100% specific for drinking within the past week, whereas 9% of the subjects without evidence of alcohol drinking for at least 1 week had EtS > 25 ng/ml. CONCLUSIONS: Urine EtG and EtS can objectively supplement the detection of recent alcohol use in patients with liver disease. Additional research may determine optimal methods for integrating these tests into clinical care.

AIMS: Hair ethyl glucuronide (EtG) is a promising biomarker of moderate-to-heavy alcohol consumption and may have utility in detecting and monitoring alcohol use in clinical populations where alcohol use is of particular importance. This study evaluated the relationship between hair EtG and drinking in patients with liver disease. METHODS: The subjects (n = 200) were patients with liver disease who presented for care at a university medical center. Alcohol use during the 3 months preceding participation in the study was assessed, and a sample of hair was obtained for EtG testing. Classification of drinking status (any drinking or averaging at least 28 g per day) by hair EtG was evaluated, as well as the effects of liver disease severity and demographic and hair care factors. RESULTS: The area under the receiver operating characteristic curve for detecting an average of 28 g or more per day during the prior 90 days was 0.93. The corresponding sensitivity and specificity of hair EtG ≥8 pg/mg for averaging at least 28 g of ethanol per day were 92 and 87%, respectively. Cirrhosis and gender may have a modest influence on the relationship between drinking and hair EtG. CONCLUSION: Hair EtG was highly accurate in differentiating subjects with liver disease averaging at least 28 g of ethanol per day from abstainers and lighter drinkers.

CONTEXT: Little systematic research has been conducted to understand pain among persons with end-stage liver disease, especially among liver transplant candidates. Appropriate pain assessment and management are important areas of consideration as treatment options are limited. OBJECTIVE: To describe the nature of chronic pain in patients with end-stage liver disease, the extent to which pain affects daily level of functioning, and the variety and effectiveness of current treatments. DESIGN: Retrospective chart review. SETTING: Academic medical center in the Southeastern United States. PATIENTS: Data were collected from 108 consecutive adult liver transplant candidates. RESULTS: Most (77%) reported having experienced moderate levels of bodily pain within the past 24 hours. Patients with only alcoholic cirrhosis reported less pain than patients with cirrhosis due to other causes (alcoholism and hepatitis C, nonalcoholic steatohepatitis, only hepatitis C). Pain interfered significantly across all 10 functional domains assessed. Although 90% reported being prescribed a variety of analgesic agents (most commonly short-acting opioids), patients reported experiencing only 33% pain relief. CONCLUSIONS: Pain is a significant problem among liver transplant candidates, and current pain treatments are perceived to be relatively ineffective. Increased understanding is needed to safely and effectively evaluate and treat such medically complicated patients.

Case series describing posttransplantation lymphoproliferative disorder (PTLD) after liver transplantation (LTx) have been limited in number because of the rarity of the disorder. The prevalence of Epstein-Barr virus (EBV) infection and its detection, the clinical and histological diversity of disease, and survival have varied. The aim of this study is to define the clinical and pathological spectrum of PTLD after LTx, and evaluate EBV prevalence, impact of infection, and patient survival. A retrospective analysis of all LTx recipients at our institution diagnosed with PTLD from January 1990 until May 2005, recording clinical presentations, times of presentation after transplantation, histological findings, results of EBV assessment, and survival, as well as the interrelationship of these variables. Among 621 LTx recipients were 22 cases of PTLD in 21 patients, of whom 5 were children and 16 were adults. Extranodal disease was present in 17 of 22 cases (77%) involving a wide variety of organ systems, while 5/22 (23%) had lymphadenopathy. The spectrum of PTLD histopathology was equally varied. In situ hybridization for EBV showed negativity in 8 of 13 (62%) and positivity in 5 of 13 (38%) cases tested. Neither time interval from transplantation to presentation (median 33 months) nor mortality (average 32%) was influenced by EBV status. In conclusion, PTLD in LTx recipients is predominantly extranodal and can involve a wide variety of organ systems, which may confound initial diagnosis. The lymphoproliferative histological spectrum is also diverse. Nowadays, PTLD is frequently EBV-negative, and EBV status does not appear to influence clinical or pathological presentation, or survival.

PURPOSE OF REVIEW: To highlight salient recent discoveries and results of clinical trials in alcoholic liver disease (ALD). The burden of care for ALD patients is hefty and the prevalence of alcohol abuse may be increasing in both the developed and the underdeveloped world. RECENT FINDINGS: Molecular mechanisms of alcoholism are being identified but not of the predisposition to alcoholic liver injury, except perhaps for polymorphism of a cytotoxic T-cell antigen. The Mayo End-stage Liver Disease (MELD) score performs well in assessing the prognosis of ALD; serological biomarkers for predicting ALD outcome are of uncertain value. Concomitant liver disease (e.g., obesity, hepatitis C, and iron overload) aggravates the severity of ALD; conversely, alcohol abuse may be a cryptic co-factor in some cases of non-alcoholic fatty liver. For alcoholic hepatitis, nutritional support is the mainstay of treatment; steroids are considered by some (but not all) as safe and effective therapy, whereas manipulations of tumor necrosis factor-alpha activity have been disappointing, or of unproven benefit at best. In liver transplantation for ALD, methods are being devised to monitor recidivism and to ameliorate its risk and that of co-morbid psychiatric conditions. SUMMARY: Much of the pathogenesis of ALD has been identified and headway has been made in predicting its prognosis. However, much remains to be done to elucidate the molecular genetics of the risk of developing ALD and in formulating safe, effective therapies for alcoholic hepatitis.

BACKGROUND & AIMS: Alpha 1 -antitrypsin deficiency (AAT) is an autosomal recessive disease that affects 1 in 2500 persons and might lead to cirrhosis. Our study aim was to characterize the liver disease in AAT and identify factors associated with advanced liver disease. METHODS: A cohort of the Alpha-1 Foundation Registry who reported liver disease was surveyed with a liver disease questionnaire to obtain information related to liver disease, liver transplantation, and AAT phenotype. RESULTS: One hundred sixty-five of the 2175 participants in the registry reported a history of jaundice or liver disease, and 139 (84.2%) completed the questionnaire. Of these, 71.3% were PiZZ, 18.0% were PiMZ, and 5.7% did not know their phenotype. Analysis of 104 participants with a known age of diagnosis included 30 participants diagnosed with liver disease before 18 years, of whom 15 had advanced liver disease defined as liver transplantation or listed for liver transplantation. No differences in age, age at diagnosis, gender, race, phenotype, or infant jaundice were identified. Seventy-four participants were diagnosed after age 18 years, of whom 25 had advanced liver disease. In this group, advanced liver disease was associated with male gender ( P = .006) and a greater mean body mass index ( P = .01), but not with race, Pi phenotype, infant jaundice, diabetes, or hypercholesterolemia. Viral hepatitis was more frequently reported in the nontransplant group (34.7% vs 8.0%, P = .01), and the mean daily alcohol use was significantly greater in this group ( P = .04). CONCLUSIONS: Our results suggest that male gender and obesity but not alcohol or viral hepatitis predispose to advanced liver disease in adults with AAT.

Mesenteric vein thrombosis is an uncommon manifestation of hypercoagulable states. A case is reported of superior mesenteric vein (SMV) thrombosis in a patient with pancreatitis and protein C deficiency. A discussion of SMV thrombosis identification, management, and outcomes is included. The patient presented with a significant history of alcohol abuse and constant, midepigastric abdominal pain associated with nausea and vomiting. Amylase and lipase were elevated, and the patient was treated for pancreatitis. His symptoms initially responded to intravenous fluid hydration, but soon his clinical picture worsened, with increased nausea and vomiting, abdominal pain, and distension. Contrasted computed tomography of the abdomen revealed SMV thrombosis. A hypercoagulable workup revealed protein C deficiency. After a 3-month course of oral anticoagulant therapy, the SMV thrombosis resolved.

BACKGROUND: Biliary stricture is one of the most common complications of liver transplantation. A number of treatment options are available, but a standard approach has not been established. METHODS: A total of 25 patients with post-liver transplantation anastomotic strictures were treated endoscopically by stent placement. Long-term outcomes (bile duct patency, morbidity, and mortality) were reviewed retrospectively. RESULTS: Placement of a stent was attempted in 25 patients with anastomotic stricture. Successful stent placement with stricture resolution at the time of stent removal was noted in 22 patients (technical success 88%). In those 22 patients, long-term success (mean follow-up after all stents removed, 54 months) was observed in 20 patients (90%) and partial success in two (10%). Long term, failure did not occur in any patient. There was no procedure- or disease-related mortally. Three mild episodes of cholangitis occurred during the period while the stents were in place, in relation to 79 endoscopic interventions for a procedure-related complication rate of 3.7%. CONCLUSIONS: The long-term outcome for patients with post-liver transplantation biliary anastomotic strictures treated with endoscopic stent placement is excellent, with no therapy- or disease-associated mortality and minimal morbidity.

OBJECTIVE: Standard esophagogastroduodenoscopy (EGD) is costly and uses conscious sedation that cirrhotic patients may tolerate poorly. This study aimed to determine the feasibility and acceptance of unsedated esophagoscopy with an ultrathin battery-powered endoscope (BPE) in cirrhotic patients for diagnosing esophageal varices (EV). METHODS: We first studied the prevalence of significant gastroduodenal pathology that could be missed if only esophagoscopy were performed in cirrhotic patients undergoing liver transplant evaluation. A prospective study was then done to evaluate a BPE in EV screening. Unsedated per-oral endoscopy was first done by a single endoscopist using a BPE, followed by EGD by a second endoscopist who was masked to the BPE result. A visual analog score was used to determine patient tolerance. Patients were asked about their preference for endoscopy in the future. A paired Student t test and the kappa statistic were used in the statistical analysis. RESULTS: In the retrospective study, 199 patients were reviewed; three patients (1.5%) had gastric ulcers, and two patients (1%) had duodenal ulcers. In the prospective study, 28 cirrhotic patients (16 women) were evaluated. EV were diagnosed in 14 patients with a BPE, and 13 were confirmed by standard EGD (sensitivity and negative predictive value 100%, specificity and positive predictive value 93%, kappa = 0.93). EV were graded as large in one and small in 13 patients with a BPE, but small varices diagnosed in one patient were not confirmed on EGD. Both procedures were well tolerated by all patients. Twenty-seven of 28 patients preferred unsedated endoscopy with a BPE over EGD. CONCLUSIONS: Unsedated endoscopy with a BPE is safe and well tolerated. The diagnostic accuracy of a BPE for diagnosing EV is the same as by EGD. Esophagoscopy with a BPE is a potential alternative to EGD for EV screening.

Therapy for veno-occlusive disease of the liver (VOD) occurring after bone marrow transplantation should be directed at those with moderate or severe disease who will not recover on their own. Thrombolytic therapy may have a role in severe VOD as long as there is no renal or lung impairment. However, the risk of bleeding complications, including the risk of cerebral hemorrhage, must be considered in these patients. Defibrotide has shown promise for treatment of severe VOD but is not yet widely available in the United States. Therapy directed at reducing portal hypertension such as transjugular intrahepatic portosystemic shunts helps reduce ascites but has no effect on mortality. Liver transplantation has been reported but should be considered only in patients with severe liver failure who would have a good outcome in the absence of liver disease or have undergone bone marrow transplantation for benign disease. The most important advances in VOD has been in the prevention of this syndrome by recognizing the risk factors for it and changes in conditioning regimens before bone marrow transplantation.
