RESUMO

BACKGROUND AND AIMS: Patients with Child-Turcotte-Pugh class B and C cirrhosis with upper gastrointestinal bleeding (UGIB) have systemic as well as localized (in the mucosa of the esophagus and stomach) fibrinolysis. The aim of this study was to evaluate the efficacy and safety of tranexamic acid in the treatment of acute UGIB in patients with cirrhosis. APPROACH AND RESULTS: A total of 600 patients with advanced liver cirrhosis (Child-Turcotte-Pugh class B or C) presenting with UGIB were randomly allocated to either the tranexamic acid (n=300) or the placebo group (n=300). The primary outcome measure was the proportion of patients developing 5-day treatment failure. Failure to control bleeding by day 5 was seen in 19/300 (6.3%) patients in the tranexamic acid group and 40/300 (13.3%) patients in the placebo group ( p =0.006). Esophageal endoscopic variceal ligation (EVL) site as a source of failure to control bleeding by day 5 among patients undergoing first-time esophageal EVL (excluding patients with a previous post-EVL ulcer as a source of bleed) was seen in 11/222 (4.9%) patients in the tranexamic acid group and 27/225 (1212.0%) patients in the placebo group ( p =0.005). However, 5-day and 6-week mortality was similar in the tranexamic acid and placebo groups. CONCLUSIONS: Tranexamic acid significantly reduces the failure to control bleeding by day 5 and failure to prevent rebleeding after day 5 to 6 weeks in patients with advanced liver cirrhosis (Child-Turcotte-Pugh class B or C) presenting with UGIB, by preventing bleeding from the EVL site.

RESUMO

BACKGROUND: The prevalence of Metabolic dysfunction associated fatty liver disease (MAFLD) and its complication, MAFLD-related acute on chronic liver failure (MAFLD-ACLF), is rising. Yet, factors determining patient outcomes in MAFLD-ACLF remain understudied. METHODS: Patients with MAFLD-ACLF were recruited from the AARC registry. The diagnosis of MAFLD-ACLF was made when the treating unit had identified the etiology of chronic liver disease (CLD) as MAFLD (or previous nomenclature such as NAFLD, NASH, or NASH-cirrhosis). Patients with coexisting other etiologies of CLD (such as alcohol, HBV, HCV, etc.) were excluded. Data was randomly split into derivation (n=258) and validation (n=111) cohorts at a 70:30 ratio. The primary outcome was 90-day mortality. Only the baseline clinical, laboratory features and severity scores were considered. RESULTS: The derivation group had 258 patients; 60% were male, with a mean age of 53. Diabetes was noted in 27%, and hypertension in 29%. The dominant precipitants included viral hepatitis (HAV and HEV, 32%), drug-induced injury (DILI, 29%) and sepsis (23%). MELD-Na and AARC scores upon admission averaged 32±6 and 10.4±1.9. At 90 days, 51% survived. Non-viral precipitant, diabetes, bilirubin, INR, and encephalopathy were independent factors influencing mortality. Adding diabetes and precipitant to MELD-Na and AARC scores, the novel MAFLD-MELD-Na score (+12 for diabetes, +12 for non-viral precipitant) and MAFLD-AARC score (+5 for each) were formed. These outperformed the standard scores in both cohorts. CONCLUSION: Almost half of MAFLD-ACLF patients die within 90 days. Diabetes and non-viral precipitants such as DILI and sepsis lead to adverse outcomes. The new MAFLD-MELD-Na and MAFLD-AARC scores provide reliable 90-day mortality predictions for MAFLD-ACLF patients.

RESUMO

BACKGROUND AND AIMS: Terlipressin infusion is effective in hepatorenal syndrome (HRS-AKI). However, its efficacy for HRS-AKI resolution in acute-on-chronic liver failure (ACLF) patients has been suboptimal. Progression of AKI is rapid in ACLF. We investigated whether early initiation of terlipressin(eTerli) can improve response rates. METHODS: Consecutive ACLF patients with stage II/III AKI despite albumin resuscitation (40 g) were randomized to receive terlipressin at 2 mg/24 h plus albumin at 12 h (ET, n = 35) or at 48 h as standard therapy (ST, n = 35). (June 22, 2020 to June 10, 2022). The primary end-point was AKI reversal by day7. RESULTS: Baseline parameters including AKI stage and ACLF-AARC scores in two arms were comparable. Full AKI response at day 7 was higher in ET [24/35 (68.6%)] than ST arm [11/35 (31.4%; P 0.03]. Day3 AKI response was also higher in ET arm [11/35 (31.4%) vs. 4/35 (11.4%), P 0.04]. Using ST compared to ET [HR 4.3; P 0.026] and day 3 serum creatinine > 1.6 mg/dl [HR 9.1; AUROC-0.866; P < 0.001] predicted HRS-AKI non-response at day 7. ET patients showed greater improvement in ACLF grade, mean arterial pressure, and urine output at day 3, and required lower albumin within 7 days than ET arm (149.1 ± 41.8 g vs. 177.5 ± 40.3 g, P 0.006) and had lower 28-day mortality: 40% vs. 65.7%, P 0.031]. Early use of terlipressin than ST [HR 2.079; P 0.038], baseline HE [HR 2.929; P 0.018], and AKI persistence at day 3 [HR 1.369; P 0.011] predicted 28-day mortality. Fifteen (21.4%) patients had treatment related adverse effects, none was life threatening. CONCLUSION: In ACLF patients, early initiation of terlipressin for AKI persisting after 12 h of volume expansion with albumin helps in reduced short-term mortality and early AKI reversal with regression of ACLF stage. These results indicate need for change in current practice for terlipressin usage in HRS-AKI.

RESUMO

BACKGROUND: Patients with cirrhosis and treatment non-responsive spontaneous bacterial peritonitis (SBP) have high mortality. We aimed to investigate whether GM-CSF can improve SBP response rates. PATIENTS AND METHODS: In this open-label RCT, 131 cirrhosis patients with difficult-to-treat SBP (DTT SBP) were randomized to receive meropenem alone (1 g IV thrice daily for 5 days) (MERO Group, n = 66) or in combination with GM-CSF (1.5 mcg/Kg daily IV till resolution or till 5d) (MEROGM Group, n = 65). The primary end-point was SBP early-response (reduction in absolute neutrophil count (ANC) by >25% after 48 h). Secondary end-points included SBP resolution at day 5. RESULTS: Patients in MEROGM group in comparison to MERO group had higher SBP early-response (60% vs. 31.8%; p = .001) and SBP resolution rates (55.4% vs. 24.2%; p = .0003). Patients in the combination arm also had better resolution of pneumonia {8/17 (47.05%) vs. 2/19 (10.5%), p = .02} and lower incidence of new-onset AKI (15.4% vs. 31.8%, p = .02), HE (18.5% vs. 34.8%, p = .04) and infections (21.5% vs. 37.9%, p = .05). In comparison to MERO group, 7-day survival was higher in MEROGM group (89.2% vs. 78.7%, p = .03), though the 28-day survival was comparable (78.4% vs. 71.2%; p = .66). None of the patients developed treatment-related severe adverse effects requiring discontinuation of therapy. CONCLUSIONS: The addition of GM-CSF to meropenem significantly improves response rates in DTT SBP patients within 48 h. Early use of GMCSF modulates host immune response, and enhances antibiotic response with higher SBP resolution. The use of GMCSF needs to be considered in combating difficult SBP in cirrhosis patients.

RESUMO

OBJECTIVES: To prospectively study the effectiveness and safety of clobazam as an add-on therapy in patients with epilepsy whose seizures are not adequately controlled with antiseizure medicine (ASM) monotherapy. METHODS: We conducted a prospective, observational study at 28 neurology outpatient clinics in India from June 2017 to October 2019. Consecutive patients with epilepsy (older than 3 years) with inadequate seizure control with ASM monotherapy were initiated on clobazam. Patients were followed up at 1, 3, 6, 9, and 12 months. Seizure control and adverse events were assessed through personal interviews and seizure diaries. RESULTS: Out of 475 eligible patients, data of 429 patients (men: 65.5%) were evaluated (46 excluded due to protocol deviations). The median age was 25 (range, 3-80 years) years and the median duration of epilepsy was 3 (0.1-30) years. The majority of patients had focal epilepsy (55.0%) and genetic generalized epilepsy (40.1%). The one-year follow-up was completed by 380 (88.5%) patients. At one-year follow-up, 317 (83.4%; N = 380) patients in the study remained seizure free. These 317 patients who were seizure free at 12 months comprised 73.9% of the evaluable population (N = 429). In 98.8% of patients, the primary reason for adding clobazam was inadequate control of seizures with treatment. During one-year follow-up, a total of 113 (22.6%) patients experienced at least one adverse event which included 103 (20.6%) patients who experienced 386 episodes of seizures. CONCLUSION: The study provides preliminary evidence that clobazam is effective and well-tolerated as add-on therapy for a period of one year among patients with epilepsy inadequately stabilized with monotherapy. TRIAL REGISTRATION NUMBER: CTRI/2017/12/010906.

RESUMO

BACKGROUND AND AIMS: Feed intolerance (FI) is common in cirrhosis patients in intensive care units (ICU). Prokinetics are the first line treatment for FI but their efficacy and safety in critically ill patient with cirrhosis is unknown. We evaluated the role of prokinetics in reversal of FI and clinical outcomes. METHODS: Consecutive patients admitted in ICU developing new-onset FI, were randomized to receive either intravenous metoclopramide (Gr.A, n = 28), erythromycin (Gr.B, n = 27) or placebo (Gr.C, n = 28). FI was defined with the presence of 3 of 5 variables- absence of bowel sounds, gastric residual volume ≥ 500 ml, vomiting, diarrhoea and bowel distension. Primary end-point was complete resolution of FI (≥ 3 variables resolved) within 24-h and secondary end-points included resolution within 72-h and survival at 7-days. RESULTS: Of the 1030 ICU patients, 201 (19.5%) developed FI and 83 patients were randomized. Baseline parameters between the groups were comparable. Complete resolution at 24-h was higher in Gr.A (7.14%) and B (22.2%) than C (0%, p = 0.017). Overall, 58 (69.9%) patients achieved resolution within 72 h, more with metoclopramide (n = 24, 85.7%) and erythromycin (n = 25, 92.6%) than with placebo (n = 9, 32.1%, p < 0.001). The 7-day survival was better in patients who achieved resolution within 72-h (65.5 vs. 36%, p = 0.011) than non-responders. High lactate (OR-3.32, CI-1.45-7.70, p = 0.005), shock at baseline (OR-6.34, CI-1.67-24.1, p = 0.007) and resolution of FI within 72 h (OR-0.11, CI, 0.03-0.51, p = 0.04) predicted 7-day mortality. CONCLUSIONS: FI is common in critically-ill cirrhosis patients and non-resolution carries high mortality. Early recognition and treatment with prokinetics is recommended to improve short-term survival.


Gastrointestinal dysmotility is common in cirrhosis and higher incidence in critically ill patients. Promotility drugs are the first line of medication especially in ICU patients. In our study, we found that feed intolerance is present in nearly one in five critically ill cirrhosis and is associated with higher mortality. Patients who achieve resolution had an improved short-term survival. Prokinetic medications are safe in critically ill cirrhosis and help in early resolution of feed intolerance. Feed intolerance in critically ill cirrhosis should be recognized as an organ dysfunction and approaches for prevention and early diagnosis of feed intolerance could help in improving the outcomes in critical illness.

RESUMO

Hepatorenal syndrome (HRS) carries a high short-term mortality in patients with cirrhosis and acute on chronic liver failure (ACLF). Terlipressin and noradrenaline are routinely used in cirrhosis with HRS and have been found to be equally effective. There are no data comparing the efficacy of terlipressin with noradrenaline in ACLF patients with HRS. In an open-label, randomized controlled trial (RCT), consecutive patients with ACLF diagnosed with HRS acute kidney injury (AKI) were randomized to albumin with infusion of terlipressin (2-12 mg/day; n = 60) or noradrenaline (0.5-3.0 mg/h; n = 60). Response to treatment, course of AKI, and outcome were studied. Baseline characteristics, including AKI stage and sepsis-related HRS-AKI, were comparable between groups. Compared to noradrenaline, terlipressin achieved greater day 4 (26.1% vs. 11.7%; P = 0.03) and day 7 (41.7% vs. 20%; P = 0.01) response. Reversal of HRS was also better with terlipressin (40% vs. 16.7%; P = 0.004), with a significant reduction in the requirement of renal replacement therapy (RRT; 56.6% vs. 80%; P = 0.006) and improved 28-day survival (48.3% vs. 20%; P = 0.001). Adverse events limiting use of drugs were higher with terlipressin than noradrenaline (23.3% vs. 8.3%; P = 0.02), but were reversible. On multivariate analysis, high Model for End-Stage Liver Disease (MELD; odds ratio [OR], 1.10; confidence interval [CI] = 1.009-1.20; P = 0.03) and noradrenaline compared to terlipressin (OR, 3.05; CI = 1.27-7.33; P = 0.01) predicted nonresponse to therapy. Use of noradrenaline compared to terlipressin was also predictive of higher mortality (hazard ratio [HR], 2.08; CI = 1.32-3.30; P = 0.002). Conclusion: AKI in ACLF carries a high mortality. Infusion of terlipressin gives earlier and higher response than noradrenaline, with improved survival in ACLF patients with HRS-AKI.

RESUMO

BACKGROUND AND AIMS: Paracentesis-induced circulatory dysfunction (PICD) is a serious complication of large-volume (>5 L) paracentesis in cirrhosis and is reduced with albumin infusion. There is a lack of data on PICD in acute-on-chronic liver failure (ACLF). Because ACLF patients have greater hemodynamic derangements than patients with decompensated cirrhosis, we investigated whether PICD could develop with modest-volume paracentesis (MVP) and the role of albumin infusion. APPROACH AND RESULTS: A total of 80 ACLF patients undergoing <5 L paracentesis were randomized to receive albumin (8 g/dL of ascitic fluid; n = 40) or no albumin (n = 40) and serially followed to detect PICD. Baseline characteristics were comparable between groups, including volume of ascitic tap (4.16 ± 0.23 versus 4.14 ± 0.27 L; P = 0.72) and plasma renin activity (PRA; 20.5 ± 7.03 versus 23.2 ± 8.24 ng/mL/hour; P = 0.12). PICD was more frequent in the no-albumin group than the albumin group (70% versus 30%; P = 0.001), with higher incidence of hepatic encephalopathy (50% versus 27.5%; P = 0.04), hyponatremia (67.5% versus 22.5%; P < 0.001), acute kidney injury (62.5% versus 30%; P = 0.001), and in-house mortality (62.5% versus 27.5%; P = 0.003). PRA of 25.15 ng/mL at day 3 had sensitivity and specificity of 71% and 68%, respectively, for development of PICD at day 6. Albumin infusion decreased the incidence of PICD at day 6 (odds ratio, 0.068; 95% confidence interval, 0.011-0.43; P = 0.005). CONCLUSIONS: PICD is common and develops even with MVP in ACLF patients. Albumin infusion decreases the incidence of PICD and mortality in patients with ACLF. Clinical trial identifier: NCT02467348.

RESUMO

INTRODUCTION: Beta-blockers are the mainstay agents for portal pressure reduction and to modestly reduce hepatic venous pressure gradient (HVPG). We studied whether addition of simvastatin to carvedilol in cirrhotic patients for primary prophylaxis improves the hemodynamic response. METHODS: Cirrhotic patients with esophageal varices and with baseline HVPG > 12 mm Hg were prospectively randomized for primary prophylaxis to receive either carvedilol (group A, n = 110) or carvedilol plus simvastatin (group B, n = 110). Primary objective was to compare hemodynamic response (HVPG reduction of ≥20% or <12 mm Hg) at 3 months, and secondary objectives were to compare first bleed episodes, death, and adverse events. RESULTS: The groups were comparable at baseline. The proportion of patients achieving HVPG response at 3 months was comparable between groups (group A-36/62 [58.1%], group B-36/59 [61%], P = 0.85). The degree of mean HVPG reduction (17.3% and 17.8%, respectively, P = 0.98) and hemodynamic response (odds ratio [OR]: 0.88; 95% confidence interval [CI]: 0.43-1.83, P = 0.74) was also not different between the groups. Patients who achieved target heart rate with no hypotensive episodes in either group showed better hemodynamic response (77.8% vs 59.2%, P = 0.04). Failure to achieve target heart rate (OR: 0.48; 95% CI: 0.22-1.06) and Child C cirrhosis (OR: 4.49; 95% CI: 1.20-16.8) predicted nonresponse. Three (3.7%) patients on simvastatin developed transient transaminitis and elevated creatine phosphokinase and improved with drug withdrawal. Two patients in each group bled (P = 0.99). Three patients and 1 patient, respectively, in group A and B died (P = 0.32), with sepsis being the cause of death. DISCUSSION: Addition of simvastatin to carvedilol for 3 months for primary prophylaxis of variceal bleeding does not improve hemodynamic response over carvedilol monotherapy. Simvastatin usage should be closely monitored for adverse effects in Child C cirrhotic patients.

RESUMO

BACKGROUND: Parkinsonism like features can be seen in cirrhotics, possibly related to alterations in brain dopamine metabolism, transport and receptor integrity at basal ganglia. Hepatic parkinsonism is often not suspected and only ammonia-reducing therapies are given to such patients. We investigated the efficacy and safety of bromocriptine, a dopaminergic agent, in patients with hepatic parkinsonism. PATIENTS AND METHODS: Cirrhotics were screened for the presence of extrapyramidal symptoms and were diagnosed as hepatic parkinsonism if any two of tremor, bradykinesia and/or rigidity were present, supported by MRI brain showing T1 hyperintensities in basal ganglia and substantia nigra. Patients were randomized to receive placebo (Gr A, n = 22) or bromocriptine (Gr B, n = 24) for 12 weeks. Complete, partial and non-response were defined as 30%, 10%-30% and <10% reduction,respectively, in Unified Parkinson's Disease Rating Scale motor score. RESULTS: Of 1016 cirrhotics, 50 (4.9%) had hepatic parkinsonism. Patients in two treatment groups were comparable for MELD score, arterial NH3 and frequency of portosystemic shunts. Bromocriptine therapy for 12 weeks resulted in improvement in rigidity, tremors, bradykinesia and gait compared to placebo with complete and partial response in seven vs none (29.1%, 0%, P < 0.01) and 12 vs one (50%, 4.5%, P < 0.01) patients. Prolonged and more severe motor symptoms were associated with non-response to bromocriptine therapy. There were no major side effects in either treatment group. CONCLUSIONS: Hepatic parkinsonism is seen in ~5% cirrhotics. Bromocriptine is a safe and effective therapy for these patients and is more effective in mild to moderate hepatic parkinsonism.

RESUMO

BACKGROUND AND AIMS: Albumin modifications and deranged functions are well documented in serum of severe alcoholic hepatitis (SAH). We investigated whether urinary albumin (u-Alb) can serve as surrogate marker of circulatory albumin phenotype, functionality, and could predict outcome in SAH patients. PATIENTS AND METHODS: Baseline serum and urine samples from 100 SAH, 20 alcoholic cirrhosis, and 20 healthy controls were subjected to u-Alb, ischemia modified albumin (IMA), IMA to albumin ratio (IMAr), advanced oxidation protein products, advanced glycation end-products, albumin-binding capacity determination. In addition, SAH urinary samples were also analyzed at day 4 and day 7 to predict nonresponse to corticosteroid therapy. RESULTS: Urine and serum levels of IMA, advanced oxidation protein products and advanced glycation end-products were higher (P<0.05) in SAH versus alcoholic cirrhosis and healthy controls. IMAr was low in urine but high in serum of SAH (P<0.05). Albumin-binding capacity was lower (P<0.05) in both urinary and serum albumin of SAH. Urinary and serum albumin parameters showed direct correlation, whereas IMAr showed inverse correlation (cc>0.2, P<0.05). Baseline u-Alb level was significantly higher in SAH, and was correlated directly with corticosteroid treatment outcome and 12-month mortality in SAH. Baseline u-Alb showed an area under the receivers operating curve analysis of 0.7 and a hazard ratio of 1.23 for prediction of 12-month mortality in SAH. Baseline u-Alb level >9.0 mg/dL was associated with reduced 12-month survival in SAH (log rank <0.01). CONCLUSIONS: u-Alb modifications are reflective of serum albumin modifications. Further baseline u-Alb levels could be exploited to predict steroid response and mortality in SAH patients.

RESUMO

BACKGROUND & OBJECTIVES: Psoriasis is a recurrent hyper-proliferative skin disease which is often associated with free radical generation, abnormal lipid metabolism and increased inflammatory secretion that induce cardiovascular risk in these patients. The present study was intended to evaluate serum lipids, lipoprotein and oxidants-antioxidants status and to establish their relationship with atherogenic risk markers [oxidized low-density lipoprotein (oxLDL) and high-sensitivity C-reactive protein (hsCRP)] in patients with psoriasis. METHODS: The study was conducted on 150 psoriasis patients and 150 age- and sex-matched healthy controls. Overnight fasting blood samples were obtained for lipids, lipoproteins, lipid oxidation and peroxidation products [oxLDL, malondialdehyde (MDA)], antioxidant enzymes [reduced glutathione (GSH) and total antioxidant status] levels and hsCRP estimations. RESULTS: The mean levels of atherogenic lipids [total cholesterol (P<0.001), triacylglycerol (P<0.01)], lipid peroxidation products (P<0.001) and oxLDL and hsCRP (P<0.001) levels in patients with psoriasis were found to be significantly higher than those of healthy controls. On the other hand, ferric-reducing ability of plasma (FRAP, P<0.001) and antioxidant enzyme activities (reduced GSH, P<0.01) were significantly lower when compared to healthy controls. The plasma oxLDL was positively correlated to LDL cholesterol (P<0.001) and MDA (P<0.001) and negatively associated with antioxidant status in these patients. Serum MDA, FRAP and oxLDL were correlated with risk of atherosclerosis in the patients with psoriasis; however, no significant association was found between reduced GSH and hsCRP. INTERPRETATION & CONCLUSIONS: The study results suggest that LDL oxidation and reactive oxygen species in addition to inflammatory markers may play a pivotal role in inducing atherosclerosis in patients of psoriasis.

RESUMO

1. Asunaprevir (ASV, BMS-650032), a highly selective and potent NS3 protease inhibitor, is currently under development for the treatment of chronic hepatic C virus infection. This study describes in vivo biotransformation in humans and the identification of metabolic enzymes of ASV. 2. Following a single oral dose of [(14)C]ASV to humans, the majority of radioactivity (>73% of the dose) was excreted in feces with <1% of the dose recovered in urine. Drug-related radioactivity readily appeared in circulation and the plasma radioactivity was mainly attributed to ASV. A few minor metabolites were observed in human plasma and are not expected to contribute to the pharmacological activity because of low levels. The area under the curve (AUC) values of each circulating metabolite in humans were well below their levels in animals used in the long-term toxicological studies. In bile and feces, intact ASV was a prominent radioactive peak suggesting that both metabolism and direct excretion played important roles in ASV clearance. 3. The primary metabolic pathways of ASV were hydroxylation, sulfonamide hydrolysis and the loss of isoquinoline. In vitro studies with human cDNA expressed CYP enzymes and with human liver microsomes (HLM) in the presence of selective chemical inhibitors demonstrated that ASV was primarily catalyzed by CYP3A4 and CYP3A5.

RESUMO

Neurocristic hamartoma (NH) is a rare dermal melanocytic lesion that is formed due to the aberrant development of neural crest-derived melanocytes during their course of migration through the dermis at the time of embryogenesis. Here, we describe a case of NH in a 6-year-old boy who clinically presented with diffuse plaque-type blue nevus on his scalp with a contiguous extension into the cervical region and lymph node involvement. A subcutaneous nodule displaying a marked histological heterogeneity with lymph node involvement is a very unusual and diagnostically challenging presentation of NH. The importance of an accurate diagnosis of NH lies in the fact that malignant transformation can rarely occur within these lesions over an unpredictable time course and remain undetected, rendering clinical management difficult. Although our child had a benign course after a follow-up of 5 years despite lymph node involvement, the possible risk of development of malignant melanoma in such a lesion warrants long-term surveillance. This case report highlights the unusual clinical presentation and histopathological features of this rare entity along with a relevant review of the literature. The present case also underscores the concept that sentinel lymph node involvement in certain melanocytic lesions in children must not be mistaken for malignant melanoma.

RESUMO

BACKGROUND: Propranolol, a non-selective beta-blocker, commonly used to prevent variceal bleed, but might precipitate circulatory dysfunction in severe ascites. Midodrine, an alpha-1 adrenergic agonist improves renal perfusion and systemic hemodynamics. Addition of midodrine might facilitate higher maximum tolerated dose (MTD) of propranolol, thereby less risk of variceal bleed in cirrhosis patients with severe ascites. METHODS: 140 patients with cirrhosis and severe/refractory ascites were randomized- propranolol and midodrine (Gr.A,n = 70) or propranolol alone (Gr.B,n = 70). Primary outcome was incidence of bleed at 1 year. Secondary outcomes included ascites control, achievement of target heart rate (THR), HVPG response and adverse effects. RESULTS: Baseline characteristics were comparable between two groups. Cumulative incidence of bleed at 1 year was lower in Gr.A than B (8.5%vs.27.1%,p-0.043). The MTD of propranolol was higher in Gr.A (96.67 ± 36.6 mg vs. 76.52 ± 24.4 mg; p-0.01) and more patients achieved THR (84.2%vs.55.7%,p-0.034). Significantly higher proportion of patients in Gr.A had complete resolution of ascites [17.1%vs.11.4%,p-0.014), diuretic tolerance (80%vs.60%,p-0.047) at higher doses(p-0.02) and lesser need for paracentesis. Patients in Gr.A also had greater reduction in variceal grade (75.7%vs.55.7%;p-0.01), plasma renin activity (54.4% from baseline) (p = 0.02). Mean HVPG reduction was greater in Gr.A than B [4.38 ± 2.81 mmHg(23.5%) vs. 2.61 ± 2.87 mmHg(14.5%),p-0.045]. Complications like post-paracentesis circulatory dysfunction and spontaneous bacterial peritonitis on follow-up were higher in Gr.B than A (22.8%vs.51.4%,p = 0.013 and 10%vs.15.7%, p = 0.03, respectively). CONCLUSION: Addition of midodrine facilitates effective use of propranolol in higher doses and greater HVPG reduction, thereby preventing first variceal bleed, reduced paracentesis requirements with fewer ascites- related complications in patients with cirrhosis with severe/refractory ascites.

RESUMO

Background and aims: A high proportion of hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (CHB) patients develop clinical relapse after stopping long-term nucleotide analogues (NAs). The aim of this study was to assess the efficacy of pegylated interferon (PEG-IFN) alpha 2b in inducing hepatitis B surface antigen (HBsAg) loss in such patients. Methods: NAs were stopped in 118 HBeAg-negative CHB patients fulfilling the Asian Pacific Association for the Study of Liver (APASL) 2015 criteria for stopping NAs; they had received NAs for a median interquartile range (IQR) of 60 (48-84) months. Results: Overall, 82 of 118 (69.5%) patients developed clinical relapse after stopping NAs; 44 within 12 months (and treated with PEG-IFN alpha 2b 1.5 mcg/kg weekly subcutaneous injections for 48 weeks); and 38 after 12 months [and treated with tenofovir alafenamide fumarate (TAF) 25 mg daily] of follow-up. The decision to treat with either PEG-IFN or TAF was not a time-bound decision but was due to logistical problems.During the median IQR follow-up of 48 (43.5-52.5) months after the start of PEG-IFN, 14 of 44 (31.8%) patients developed clinical relapse after stopping PEG-IFN and were started on TAF. At the last follow-up visit, HBsAg was found to be negative in 7/44 (15.9%) of patients receiving PEG-IFN.Among 38 patients treated with TAF for clinical relapse, during the median IQR follow-up of 18 (12-30) months after start of TAF, no patient became HBsAg negative.36 patients did not develop clinical relapse during the follow-up, and after a median IQR follow-up of 60 (60-60) months after stopping NAs, HBsAg negative was found in 1/36 (2.8%) of patient at the last follow-up. Conclusions: Among patients with HBeAg-negative chronic hepatitis B who developed clinical relapse after stopping long-term NAs therapy and were subsequently treated with PEG-IFN alpha 2b, 15.9% achieved HBsAg loss on long-term follow-up.

RESUMO

BACKGROUND/AIMS: Quick sequential organ failure assessment (qSOFA) is believed to identify patients at risk of poor outcomes in those with suspected infection. We aimed to evaluate the ability of modified qSOFA (m-qSOFA) to identify high-risk patients among those with acutely deteriorated chronic liver disease (CLD), especially those with acute-onchronic liver failure (ACLF). METHODS: We used data from both the Korean Acute-on-Chronic Liver Failure (KACLiF) and the Asian Pacific Association for the Study of the Liver ACLF Research Consortium (AARC) cohorts. qSOFA was modified by replacing the Glasgow Coma Scale with hepatic encephalopathy, and an m-qSOFA ≥2 was considered high. RESULTS: Patients with high m-qSOFA had a significantly lower 1-month transplant-free survival (TFS) in both cohorts and higher organ failure development in KACLiF than those with low m-qSOFA (Ps<0.05). Subgroup analysis by ACLF showed that patients with high m-qSOFA had lower TFS than those with low m-qSOFA. m-qSOFA was an independent prognostic factor (hazard ratios, HR=2.604, 95% confidence interval, CI 1.353-5.013, P=0.004 in KACLiF and HR=1.904, 95% CI 1.484- 2.442, P<0.001 in AARC). The patients with low m-qSOFA at baseline but high m-qSOFA on day 7 had a significantly lower 1-month TFS than those with high m-qSOFA at baseline but low m-qSOFA on day 7 (52.6% vs. 89.4%, P<0.001 in KACLiF and 26.9% vs. 61.5%, P<0.001 in AARC). CONCLUSION: Baseline and dynamic changes in m-qSOFA may identify patients with a high risk of developing organ failure and short-term mortality among CLD patients with acute deterioration.
