Project description:BackgroundPortal hypertension, a major complication of chronic liver disease, often leads to life-threatening variceal bleeding, managed effectively with vasoactive drugs like terlipressin. However, the most optimal method of terlipressin administration, continuous versus intermittent infusion, remains a subject of debate, necessitating this systematic review and meta-analysis for evidence-based decision-making in managing this critical condition.MethodsThis systematic review and meta-analysis adhered to the PRISMA standards and explored multiple databases until 6 April 2023, such as MEDLINE through PubMed, Scopus, Web of Science, and CENTRAL. Independent reviewers selected randomized controlled trials (RCTs) that met specific inclusion criteria. After assessing study quality and extracting necessary data, statistical analysis was performed using Review Manager (RevMan), with results presented as risk ratios (RR) or mean differences.ResultsFive RCTs (n=395 patients) were included. The continuous terlipressin group had a significantly lower risk of rebleeding (RR=0.43, P=0.0004) and treatment failure (RR=0.22, P=0.02) and fewer total adverse effects (RR=0.52, P<0.00001) compared to the intermittent group. However, there were no significant differences between the two groups in mean arterial pressure (P=0.26), length of hospital stays (P=0.78), and mortality rates (P=0.65).ConclusionThis study provides robust evidence suggesting that continuous terlipressin infusion may be superior to intermittent infusions in reducing the risk of rebleeding, treatment failure, and adverse effects in patients with portal hypertension. However, further large-scale, high-quality RCTs are required to confirm these findings and to investigate the potential benefits of continuous terlipressin infusion on mortality and hospital stays.

Project description:IntroductionRecent clinical data suggest that early administration of vasopressin analogues may be advantageous compared to a last resort therapy. However, it is still unknown whether vasopressin and terlipressin are equally effective for hemodynamic support in septic shock. The aim of the present prospective, randomized, controlled pilot trial study was, therefore, to compare the impact of continuous infusions of either vasopressin or terlipressin, when given as first-line therapy in septic shock patients, on open-label norepinephrine requirements.MethodsWe enrolled septic shock patients (n = 45) with a mean arterial pressure below 65 mmHg despite adequate volume resuscitation. Patients were randomized to receive continuous infusions of either terlipressin (1.3 microg.kg-1.h-1), vasopressin (.03 U.min-1) or norepinephrine (15 microg.min-1; n = 15 per group). In all groups, open-label norepinephrine was added to achieve a mean arterial pressure between 65 and 75 mmHg, if necessary. Data from right heart and thermo-dye dilution catheterization, gastric tonometry, as well as laboratory variables of organ function were obtained at baseline, 12, 24, 36 and 48 hours after randomization. Differences within and between groups were analyzed using a two-way ANOVA for repeated measurements with group and time as factors. Time-independent variables were compared with one-way ANOVA.ResultsThere were no differences among groups in terms of systemic and regional hemodynamics. Compared with infusion of .03 U of vasopressin or 15 microg.min-1 of norepinephrine, 1.3 microg.kg-1.h-1 of terlipressin allowed a marked reduction in catecholamine requirements (0.8 +/- 1.3 and 1.2 +/- 1.4 vs. 0.2 +/- 0.4 microg.kg-1.min-1 at 48 hours; each P < 0.05) and was associated with less rebound hypotension (P < 0.05). At the end of the 48-hour intervention period, bilirubin concentrations were higher in the vasopressin and norepinephrine groups as compared with the terlipressin group (2.3 +/- 2.8 and 2.8 +/- 2.5 vs. 0.9 +/- 0.3 mg.dL-1; each P < 0.05). A time-dependent decrease in platelet count was only observed in the terlipressin group (P < 0.001 48 hours vs. BL).ConclusionsThe present study provides evidence that continuous infusion of low-dose terlipressin--when given as first-line vasopressor agent in septic shock--is effective in reversing sepsis-induced arterial hypotension and in reducing norepinephrine requirements.

Project description:Terlipressin with albumin, the recommended treatment for hepatorenal syndrome-acute kidney injury (HRS-AKI), is associated with adverse events. Furthermore, the course of AKI in patients with acute-on-chronic liver failure (ACLF) is unknown. We aimed to analyze the safety and efficacy of terlipressin infusion and AKI course in patients with ACLF. We prospectively enrolled consecutive adult patients with ACLF with HRS-AKI (satisfying EASL criteria) treated with terlipressin infusion between 14 October 2019 and 24 July 2020. The objectives were to assess the incidence of adverse events, response to terlipressin, course of HRS-AKI and predictors of mortality. A total of 116 patients were included. Twenty-one percent of patients developed adverse effects. Only 1/3rd of patients who developed adverse events were alive at day 90. Sixty-five percent of the patients responded to terlipressin. Nearly 22% developed recurrence of HRS, and 5.2% progressed to HRS-chronic kidney disease. TFS was 70.4% at day 30 and 57.8% at day 90. On multivariate stepwise Cox regression analysis terlipressin non-response (hazard ratio [HR], 3.49 [1.85-6.57]; P < 0.001) and MELD NA score (HR,1.12 [1.06-1.18]; P < 0.001) predicted mortality at day-90. Patients with ACLF who develop terlipressin related adverse events have dismal prognoses. Terlipressin non-response predicts mortality in patients with ACLF and HRS-AKI.

Project description:Background & aimsPortal hypertension contributes to the pathogenesis of malnutrition and sarcopenia in cirrhosis via multiple mechanisms. Terlipressin is a vasopressin analogue that we administer via continuous outpatient infusion, as a bridge to transplantation in patients with hepatorenal syndrome or refractory ascites. We describe, for the first time, the impact of outpatient terlipressin on nutritional and muscle parameters.MethodsNutrition (subjective global assessment), handgrip strength, dietary intake (energy, protein), frequency of paracentesis and severity of liver disease (model for end-stage liver disease score) were prospectively recorded at terlipressin commencement and follow-up (transplantation, cessation or census date).ResultsNineteen patients were included (89% male, median age 59.6 years, median model for end-stage liver disease score 24), of whom 12 had hepatorenal syndrome and 7 had refractory ascites. All patients were malnourished at baseline, 63% (n = 12) had sarcopenic-range grip strength, and mean paracentesis frequency was 2.86 ± 1.62/month. Median duration of terlipressin was 51 days (interquartile range 29-222). Fourteen patients (74%) were transplanted, 2 delisted (10%) and 3 (16%) continued terlipressin. Energy and protein intake improved significantly following terlipressin, from 17.94 ± 5.43 kcal/kg to 27.70 ± 7.48 kcal/kg, and 0.74 ± 0.28 g/kg to 1.16 ± 0.31 g/kg, respectively (both p < 0.001). Handgrip strength increased from 25.36 ± 8.13 kg to 28.49 ± 7.63 kg (p = 0.001). Linear regression analysis demonstrated hand grip strength increased 0.075% for every 1-day of terlipressin (p = 0.005). The frequency of large-volume paracentesis reduced by 46%, to 1.57 ± 1.51/month (p = 0.001).ConclusionContinuous terlipressin infusion reduces the complications of portal hypertension and is associated with an improvement in nutritional and muscle parameters in patients on the liver transplant waiting list, in whom such characteristics usually demonstrate progressive decline. This validates both the aetiological role of portal hypertension in malnutrition and represents a promising new anabolic therapy.Lay summaryMalnutrition and poor muscle strength are common in liver disease and often get worse while patients await liver transplant. Terlipressin is a medication used to treat portal hypertension in patients with hepatorenal syndrome. It is usually given for a few days or weeks in patients confined to hospital. Our centre provides outpatient terlipressin for weeks to months as a bridge to liver transplant. In patients treated with terlipressin at our hospital, we observed a substantial increase in their dietary intake and muscle strength, which may improve their quality of life and outcomes after liver transplant.

Project description:Vasospasm immediately after lower extremity arterial bypass may represent an uncommon cause of early graft failure. We report a successful case of catheter-directed, intra-arterial continuous vasodilator infusion to salvage a bypass graft threatened by severe, refractory vasospasm after incomplete response to nicardipine, verapamil, and nitroglycerin boluses. A continuous nitroglycerin infusion was administered for 24 hours, by which time the vasospasm resolved. At 12 months postoperatively, the graft remained patent with normal results of vascular laboratory studies. This report demonstrates that in cases of refractory vasospasm after peripheral bypass, continuous vasodilator infusion can be an effective treatment to prevent early graft failure.

Project description:Background & aimsAdministration of terlipressin plus albumin is effective in reversing type 1 HRS as compared to albumin alone. However, only about 1/3 of patients respond to treatment, therefore, predictors of response and survival would help identify the patients most likely to benefit from treatment.MethodsWe analyzed our controlled trial of terlipressin vs. placebo (Gastroenterology 2008;134:1360) to define factors predictive of a response and to correlate hemodynamic changes to changes in renal function.ResultsSingle variant analysis showed treatment with terlipressin, MELD score, and baseline serum creatinine to be predictive of HRS reversal. Alcoholic hepatitis, baseline serum creatinine, and MELD score were predictive of survival. When treatment was not considered as a variable, only baseline serum creatinine predicted HRS reversal. Baseline serum creatinine, presence of alcoholic hepatitis, and Child-Pugh score were also predictive of survival on multivariate analysis. The rise in mean arterial pressure (MAP) following terlipressin administration was not predictive of HRS reversal. However, in those who achieved HRS reversal from terlipressin, there was a significant rise in MAP from beginning to end of treatment.ConclusionsThe most consistent predictor of response to terlipressin and of survival is the baseline serum creatinine. Patients most likely to benefit from terlipressin have earlier onset renal failure (i.e. serum creatinine <5.0mg/dl). A sustained rise in MAP is required for HRS reversal. As MAP is a surrogate marker for the hyperdynamic circulation, it is only with improvement in the hyperdynamic circulation that HRS reversal is observed.

Project description:Background/purposeTreat-to-target (TTT) is a recommended strategy in the management of rheumatoid arthritis (RA), but various data sources suggest that its uptake in routine care in the US is suboptimal. Herein, we describe the design of a randomized controlled trial of a Learning Collaborative to facilitate implementation of TTT.MethodsWe recruited 11 rheumatology sites from across the US and randomized them into the following two groups: one received the Learning Collaborative intervention in Phase 1 (month 1-9) and the second formed a wait-list control group to receive the intervention in Phase 2 (months 10-18). The Learning Collaborative intervention was designed using the Model for Improvement, consisting of a Change Package with corresponding principles and action phases. Phase 1 intervention practices had nine learning sessions, collaborated using a web-based tool, and shared results of plan-do-study-act cycles and monthly improvement metrics collected at each practice. The wait-list control group sites had no intervention during Phase 1. The primary trial outcome is the implementation of TTT as measured by chart review, comparing the differences from baseline to end of Phase 1, between intervention and control sites.ResultsAll intervention sites remained engaged in the Learning Collaborative throughout Phase 1, with a total of 38 providers participating. The primary trial outcome measures are currently being collected by the study team through medical record review.ConclusionsIf the Learning Collaborative is an effective means for improving implementation of TTT, this strategy could serve as a way of implementing disseminating TTT more widely.

Project description:OBJECTIVE:Despite numerous improvements in care, morbidity from heart failure (HF) has remained essentially unchanged in recent years. One potential reason is that depression, which is comorbid in approximately 40% of hospitalized HF patients and associated with adverse HF outcomes, often goes unrecognized and untreated. The Hopeful Heart Trial is the first study to evaluate whether a widely generalizable telephone-delivered collaborative care program for treating depression in HF patients improves clinical outcomes. METHODS:The Hopeful Heart Trial aimed to enroll 750 patients with reduced ejection fraction (HFrEF) (ejection fraction ? 45%) including the following: (A) 625 patients who screened positive for depression both during their hospitalization (Patient Health Questionnaire [PHQ-2]) and two weeks following discharge (PHQ-9 ? 10); and (B) 125 non-depressed control patients (PHQ-2(-)/PHQ-9 < 5). We randomized depressed patients to either their primary care physician's "usual care" (UC) or to one of two nurse-delivered 12-month collaborative care programs for (a) depression and HFrEF ("blended") or (b) HrEFF alone (enhanced UC). Our co-primary hypotheses will test whether "blended" care can improve mental health-related quality of life versus UC and versus enhanced UC, respectively, on the Mental Component Summary of the Short-Form 12 Health Survey. Secondary hypotheses will evaluate the effectiveness of our interventions on mood, functional status, hospital readmissions, deaths, provision of evidence-based care for HFrEF, and treatment costs. RESULTS:Not applicable. CONCLUSIONS:The Hopeful Heart Trial will determine whether "blended" collaborative care for depression and HFrEF is more effective at improving patient-relevant outcomes than collaborative care for HFrEF alone or doctors' UC for HFrEF.

Project description:Erratic blood glucose levels can be a cause and consequence of delayed gastric emptying in patients with diabetes. It is unknown if better glycemic control increases risks of hypoglycemia or improves hemoglobin A1c levels and gastrointestinal symptoms in diabetic gastroparesis. This study investigated the safety and potential efficacy of continuous subcutaneous insulin infusion (CSII) and continuous glucose monitoring (CGM) in poorly controlled diabetes with gastroparesis. Forty-five type 1 or 2 patients with diabetes and gastroparesis and hemoglobin A1c >8% from the NIDDK Gastroparesis Consortium enrolled in a 24 week open-label pilot prospective study of CSII plus CGM. The primary safety outcome was combined numbers of mild, moderate, and severe hypoglycemic events at screening and 24 weeks treatment. Secondary outcomes included glycemic excursions on CGM, hemoglobin A1c, gastroparesis symptoms, quality-of-life, and liquid meal tolerance. Combined mild, moderate, and severe hypoglycemic events occurred similarly during the screening/run-in (1.9/week) versus treatment (2.2/week) phases with a relative risk of 1.18 (95% CI 0.85-1.64, P = 0.33). CGM time in hypoglycemia (<70 mg/dL) decreased from 3.9% to 1.8% (P<0.0001), time in euglycemia (70-180 mg/dL) increased from 44.0% to 52.0% (P = 0.02), time in severe hyperglycemia (>300 mg/dL) decreased from 14.2% to 7.0% (P = 0.005), and hemoglobin A1c decreased from 9.4±1.4% to 8.3±1.3% (P = 0.001) on CSII plus CGM. Symptom scores decreased from 29.3±7.1 to 21.9±10.2 with lower nausea/vomiting, fullness/early satiety, and bloating/distention scores (P≤0.001). Quality-of-life scores improved from 2.4±1.1 to 3.1±1.1 (P<0.0001) and volumes of liquid nutrient meals tolerated increased from 420±258 to 487±312 mL (P = 0.05) at 24 weeks. In conclusion, CSII plus CGM appeared to be safe with minimal risks of hypoglycemic events and associated improvements in glycemic control, gastroparesis symptoms, quality-of-life, and meal tolerance in patients with poorly controlled diabetes and gastroparesis. This study supports the safety, feasibility, and potential benefits of improving glycemic control in diabetic gastroparesis.

Project description:BACKGROUND:Both Deep Brain Stimulation (DBS) and Continuous intrajejunal Levodopa Infusion (CLI) are effective therapies for the treatment of Parkinson's disease (PD). To our knowledge, no direct head-to-head comparison of DBS and CLI has been performed, whilst the costs probably differ significantly. In the INfusion VErsus STimulation (INVEST) study, costs and effectiveness of DBS and CLI are compared in a randomized controlled trial (RCT) in patients with PD, to study whether higher costs of one of the therapies are justified by superiority of that treatment. METHODS:A prospective open label multicentre RCT is being performed, with ancillary patient preference observational arms. Patients with PD who, despite optimal pharmacological treatment, have severe response fluctuations, bradykinesia, dyskinesias, or painful dystonia are eligible for inclusion. A total of 66 patients will be randomized. There is no minimal inclusion in the patient preference arms. The primary health economic outcomes are costs per unit on the Parkinson's Disease Questionnaire-39 (PDQ-39) and costs per unit Quality-Adjusted Life Year (QALY) at 12 months. The main clinical outcome is patient-reported quality of life measured with the PDQ-39 at 12 months. Patients will additionally be followed during 36 months after initiation of the study treatment. DISCUSSION:The INVEST trial directly compares the costs and effectiveness of the advanced therapies DBS and CLI. TRIAL REGISTRATION:Dutch Trial Register identifier 4753, registered November 3rd, 2014; EudraCT number 2014-001501-32, Clinicaltrials.gov: NCT02480803.
