Pediatr Transplant 2024; 28:e14654. [PMID: 37983943 DOI: 10.1111/petr.14654] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Revised: 10/26/2023] [Accepted: 11/06/2023] [Indexed: 11/22/2023]
Abstract
BACKGROUND Pediatric acute liver failure (PALF) is one of the most demanding emergencies in hepatology, intensive care, and for transplant team. This report describes the clinical pattern, diagnostic and therapeutic modalities in children with ALF considered at risk of death without liver transplantation, basing on a long-term experience of the pediatric transplant center. MATERIALS AND METHODS Between 1990 and 2022, 104 children aged 7 days-17 years (median 8 years), with body weight 3.1 to 77 kg (median 32 kg), were qualified for LT due to ALF, and finally 81 (78%) of them were transplanted (9% of all 899 LT performed in children in the same period). RESULTS A total of 23 children were not transplanted: 15 (14.4%) died while awaiting transplantation. In 8 (7.7%) patients liver function recovered. Before transplantation 45 (43.3%) children developed circulatory failure, in 66 (63.5%) mechanical ventilation was necessary, 18 patients presented acute kidney injury (17.3%), and encephalopathy higher than stage I was present in 60 (57.7%) patients. In 63 children, various kidney/liver assist procedures were performed: CVVHD (continuous veno-venous hemodiafiltration in 22 (21.2%) patients, albumin dialysis (MARS; molecular adsorbent recirculating system) in 39 (37.5%) patients, therapeutic plasma exchange (TPE) in 13 (12.5%) patients. Twenty (24.7%) children died after LT including 15 (18.5%) in the early posttransplant period, and 5 (6.1%) in the late follow-up. CONCLUSIONS Treatment of children with ALF in the peritransplant period is very difficult and require an experienced, multidisciplinary team. Despite continued advances in the care of children with ALF, patient survival remains lower than for elective indications for liver transplantation, and timely qualification and transplantation still are the most important factors of survival of these children.

Abstract
BACKGROUND In this report, we examine the surgical safety and complications (SC) among 125 liver (L) and 150 kidney (K) HIV+ transplantation (TX) recipients in a prospective nonrandomized U.S. multicenter trial. METHODS Subjects were required to have CD4+ T-cell counts >200/100 cells/mm3 (K/L) and undetectable plasma HIV-1 RNA (Viral Load [VL]) (K) or expected posttransplantation suppression (L). Impact of SCs (N ≥ 7) was evaluated by use of the proportional hazards models. Baseline morbidity predictors for SCs (N ≥ 7) were assessed in univariate proportional hazards models. RESULTS At median 2.7 (interquartile range 1.9-4.1) and 2.3 (1.0-3.7) years after TX, 3-month and 1-year graft survival were [K] 96% (95% CI 91%-98%) and 91% (95% CI 85%-94%) and [L] 91% (95% CI 85%-95%) and 77% (95% CI 69%-84%), respectively. A total of 14 K and 28 L graft losses occurred in the first year; 6 K and 11 L were in the first 3 months. A total of 26 (17%) K and 43 (34%) L experienced 29 and 62 SCs, respectively. In the liver multivariate model, re-exploration was marginally associated (hazard ratio [HR] 2.8; 95% CI 1.0-8.4; P = .06) with increased risk of graft loss, whereas a greater MELD score before transplantation (HR 1.07 per point increase; 95% CI: 1.01-1.14; P = .02), and detectable viral load before TX (HR 3.6; 95% CI 0.9-14.6; P = .07) was associated with an increased risk of wound infections/dehiscence. CONCLUSION The rates and outcomes of surgical complications are similar to what has been observed in the non-HIV setting in carefully selected HIV-infected liver and kidney TX recipients.

Abstract
Although liver transplantation (LT) is a highly effective treatment, it has been considered too costly for publicly funded health systems in many countries with low to medium average incomes. However, with economic growth and improving results, some governments are reconsidering this position. Cost-effectiveness data for LT are limited, especially in perioperative care, and the techniques and costs vary widely between centers without overt differences in outcomes. Anesthesiologists working in new programs find it difficult to determine which modalities are essential, which are needed only in exceptional circumstances, and which may be omitted without effects on outcomes. We investigated key elements of preoperative evaluations, intraoperative management, and early postoperative care that might significantly affect costs in order to develop a best-value approach for new programs in resource-limited health systems. We identified all modalities of care commonly used in anesthesia and perioperative care for adult LT along with their costs. Those considered to be universally accepted as minimum requirements for safe care were excluded from the analysis, and so were those considered to be safe and low-cost, even when evidence of efficacy was lacking. The remaining items were, therefore, those with uncertain or context-restricted value and significant costs. A systematic review of the published evidence, practice surveys, and institutional guidelines was performed, and the evidence was graded and summarized. With respect to costs and benefits, each modality was then cited as strongly recommended, recommended or optional, or no recommendation was made because of insufficient evidence. Sixteen modalities, which included preoperative cardiovascular imaging, venovenous bypass, pulmonary artery catheterization, high-flow fluid warming devices, drug therapies for hemostasis, albumin, cell salvage, anesthetic drugs, personnel (staffing) requirements, and early extubation, were assessed. Only high-flow fluid warming was strongly recommended. The recommended modalities included preoperative echocardiography, cell salvage, tranexamic acid and early extubation. Six others were rated optional, and there was insufficient evidence for 5 modalities. We conclude that some costly techniques and treatments can be omitted without adverse effects on outcomes.

Abstract
OBJECTIVE To determine the safety and efficacy of off label usage of Recombinant activated factor VII (rFVIIa) in children with severe bleeding in non-hemophiliac children with diverse etiologies like leukemia, post hematopoietic stem cell transplantation, dengue shock syndrome and Glanzmann thrombasthenia. METHOD Medical records of 16 non-hemophiliac children with 20 bleeding episodes where rFVIIa was administered only after failure of standard measures to control bleeding were retrospectively reviewed and data collected regarding patient demographics, diagnosis and location of bleeding. Blood counts, coagulation and other lab parameters, both pre and post rFVIIa, were also noted. Severity of bleeding was assessed using a scoring system used previously by Nevo S et al. A record of usage of the amount of blood components (red blood cells, platelets, fresh frozen plasma, and cryoprecipitate) 24 h pre and post rFVIIa was also made. The dose of rFVIIa and any adverse side effects were recorded. RESULTS Bleeding sites were gastrointestinal (13/20), pulmonary hemorrhage (6/20) and intracranial hemorrhage (1/20). Thrombocytopenia (platelet count <50,000/cumm) was present in 50% episodes and five had refractory low platelets. Usage of packed red cells and platelets was significantly less after usage of rFVIIa (p value 0.001 and 0.006, respectively). Mean dosage of rFVIIa was 77 μgm/kg/dose (range 60 to 90 μgm/kg/dose). The bleeding stopped completely in 11(55%), decreased to minimal in 2 (10%), reduced but transfusions needed in 4 (20%) and did not stop in 3 (15%) episodes. Five patients (31%) did not survive the bleeding episode. None of the patients developed thrombosis. CONCLUSIONS rFVIIa appears to be safe and effective in controlling life-threatening bleed in non-hemophiliac children.

Abstract
BACKGROUND Recombinant factor VIIa (rFVIIa), a hemostatic agent approved for hemophilia, is increasingly used for off-label indications. PURPOSE To evaluate the benefits and harms of rFVIIa use for 5 off-label, in-hospital indications: intracranial hemorrhage, cardiac surgery, trauma, liver transplantation, and prostatectomy. DATA SOURCES Ten databases (including PubMed, EMBASE, and the Cochrane Library) queried from inception through December 2010. Articles published in English were analyzed. STUDY SELECTION Two reviewers independently screened titles and abstracts to identify clinical use of rFVIIa for the selected indications and identified all randomized, controlled trials (RCTs) and observational studies for full-text review. DATA EXTRACTION Two reviewers independently assessed study characteristics and rated study quality and indication-wide strength of evidence. DATA SYNTHESIS 16 RCTs, 26 comparative observational studies, and 22 noncomparative observational studies met inclusion criteria. Identified comparators were limited to placebo (RCTs) or usual care (observational studies). For intracranial hemorrhage, mortality was not improved with rFVIIa use across a range of doses. Arterial thromboembolism was increased with medium-dose rFVIIa use (risk difference [RD], 0.03 [95% CI, 0.01 to 0.06]) and high-dose rFVIIa use (RD, 0.06 [CI, 0.01 to 0.11]). For adult cardiac surgery, there was no mortality difference, but there was an increased risk for thromboembolism (RD, 0.05 [CI, 0.01 to 0.10]) with rFVIIa. For body trauma, there were no differences in mortality or thromboembolism, but there was a reduced risk for the acute respiratory distress syndrome (RD, -0.05 [CI, -0.02 to -0.08]). Mortality was higher in observational studies than in RCTs. LIMITATIONS The amount and strength of evidence were low for most outcomes and indications. Publication bias could not be excluded. CONCLUSION Limited available evidence for 5 off-label indications suggests no mortality reduction with rFVIIa use. For some indications, it increases thromboembolism.

Abstract
OBJECTIVE To evaluate the use of recombinant factor VIIa (rFVIIa) for the treatment of bleeding in nonhemophiliac children.
METHODS This was a retrospective chart review of all patients < 18 years of age who received rFVIIa over a 2 year period.
RESULTS Twenty-four pediatric patients received a total of 240 doses of rFVIIa for treatment of bleeding. Recombinant factor VIIa was effective in achieving bleeding resolution in 54% of patients. The mean age of patients in the bleeding non-resolution versus resolution group was 50% younger (5.5 vs. 10.3 years, P = 0.104).
CONCLUSIONS Bleeding resolution can be achieved with recombinant factor VIIa using similar doses to those recommended for children with hemophilia. Widespread use of rFVIIa for bleeding in children without hemophilia is not warranted given this efficacy data. Further safety studies are needed with rFVIIa in this population to clarify thrombotic risks.

Abstract
PURPOSE The aim of this study was to analyse the changes in transfusion requirements, in patients submitted to orthotopic liver transplantation from cadaveric donors, with the use of intraoperative red blood cell salvage (Cell Saver). METHODS Data from 41 transplants were analysed. Intraoperative blood loss was calculated from the cell salvage, suction and the swabs. The autologous and heterologous transfusions were recorded The red blood salvage was performed using the Cell Saver 5 System (Haemonetics). For analysis the patients were divided in two groups: one that used the Cell Saver and another that didn't. RESULTS The median age of the patients was 50 years and the main indication for liver transplantation was cirrhosis (35 cases-85.3%). The median blood loss was 8362+3994 ml (with the Cell Saver) and 10824+7002 ml (without the Cell Saver) and the median transfusion of heterologous packed red blood cells was 9.6+8 units (with the Cell Saver) compared to 22.3+21 units (without the Cell Saver). CONCLUSIONS The Cells Saver has the potential to reduce the need for heterologous blood transfusion reducing the risks of transmissible diseases.

Abstract
BACKGROUND Recombinant activated factor VII (rFVIIa) is approved by the FDA for the treatment of bleeding episodes in patients with hemophilia A or B with inhibitors to factor VIII or factor IX. In addition to the FDA-approved indications, rFVIIa has been anecdotally reported effective for profound bleeding episodes in adult patients without hemophilia, and proven beneficial for adults with intracranial hemorrhage. In the pediatric literature, case reports have been made with apparent clinical improvement seen after the use of rFVIIa for acute life-threatening bleeding; however, there are limited data regarding its use in infants<4 months of age. We report our experience with rFVIIa in nine infants with severe hemorrhage of diverse etiologies. METHODS This case series of infants under 4 months with coagulopathy and bleeding treated with rFVIIa was collected from two institutions. We report the age, weight and pre-rFVIIa laboratory values of the patients as well as the clinical scenario and outcomes. RESULTS The nine infants all suffered acute life-threatening hemorrhage. Two patients were postoperative from cardiac surgery, two with Vitamin K deficiency and intracranial hemorrhage, three with suspected necrotizing enterocolitis and abdominal hemorrhage, and two with pulmonary hemorrhage. The patients ranged in age from 2 days to 4 months, (average age 1 month and average weight 3.3+/-1.0 kg). Seven of the nine patients had frozen plasma, cryoprecipitate, or platelet administration in failed attempts to correct the coagulation defect prior to receiving rFVIIa. The dose range used in this series was 90-100 microg.kg-1, with 90 microg.kg-1 being the most commonly used dose. The average pre-rFVIIa INR was 8.7+/-5.1. Four patients had an immeasurably high INR. All patients had clinical resolution of bleeding after receiving rFVIIa, and seven of nine patients survived. CONCLUSIONS rFVIIa is a powerful hemostatic drug whose mechanism of action provides a theoretical specificity to sites of tissue injury. In addition to its FDA-approved uses in hemophiliac patients, this drug has a potential role in the treatment of life-threatening hemorrhage from multiple causes.

Abstract
Recombinant factor VIIa (rFVIIa) has been used in haemophilia bleeding since its introduction in 1996. It has been found to be safe and effective in the majority of patients with haemophilia who have developed inhibitors. There is increasing use of rFVIIa in many off-label bleeding conditions, but there is a paucity of randomized studies regarding the use of rFVIIa in children. This review will attempt to address and summarize the studies focusing on the role of rFVIIa in both haemophilia and non-haemophilia bleeding conditions in children. rFVIIa has been administered as both bolus and continuous infusions, and at varying doses. Furthermore, adverse events have not reportedly increased in children despite growing experience with its use in the paediatric population.
