Platelet transfusion, cirrhosis

BACKGROUND: Platelet (PLT) transfusion was the most practical way to increase patients' PLT counts before invasive hepatic procedures such as radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC). A novel drug that raises the PLT count by acting on the thrombopoietin receptor has recently become available. METHODS: Lusutrombopag 3 mg was administered daily for 7 days to patients who underwent RFA for liver tumors with low PLT counts (< 50,000 PLT µL- 1 )...

BACKGROUND: Liver cirrhosis and esophageal cancer share several risk factors, such as alcohol intake and overweight. Endoscopic resection is the gold standard treatment for superficial tumors. Portal hypertension and coagulopathy may increase the bleeding risk in these patients. This study aims to assess the safety and efficacy of endoscopic resection for early esophageal neoplasia in patients with cirrhosis or portal hypertension. METHODS: This retrospective multicentric international study included consecutive patients with cirrhosis or portal hypertension who underwent endoscopic resection in the esophagus from January 2005 to March 2021...

BACKGROUND: Previous studies have found that the production of platelets could enhance the therapeutic effects of stem cells. Nevertheless, there are still no articles reporting on the relationship between platelets and the clinical efficacy of umbilical cord mesenchymal stem cells (UCMSCs) for HBV-related acute-on-chronic liver failure (ACLF) and liver cirrhosis (LC). METHODS: In this retrospective observational study, patients who met the criteria were included...

BACKGROUND AND AIMS: Recent guidelines recognize the limitations of standard coagulation tests in predicting bleeding and guiding pre-procedural blood component prophylaxis in cirrhosis. It is unclear whether these recommendations are reflected in clinical practice. We performed a nationwide survey to investigate pre-procedural transfusion practices and opinions of key health care stakeholders involved in managing cirrhosis. METHODS: We designed a 36-item multiple-choice questionnaire to investigate the international normalized ratio and platelet cutoffs utilized to guide pre-procedural transfusion of fresh frozen plasma and platelets in patients with cirrhosis undergoing a range of low and high-risk invasive procedures...

INTRODUCTION: Thromboelastography (TEG) is a functional test of coagulation used to guide transfusions. Despite literature supporting its utility, its use remains limited to select populations. In patients with cirrhosis, conventional coagulation tests are notoriously inaccurate, and TEG may be a better measure of coagulopathy. We aimed to assess the utilization of TEG in patients with cirrhosis to steward blood transfusions in this high-risk group. METHODS: A single-center retrospective chart review of all patients ≥18 y old with a diagnosis of liver cirrhosis who had TEG results documented in the electronic medical record from January 1 to November 1, 2021...

PURPOSE: To compare the peri-operative and long-term survival outcomes of minimally invasive liver resection (MILR) (robotic or laparoscopic) with open liver resection (OLR) in patients with hepatocellular carcinoma (HCC). METHODS: Data of patients who underwent liver resection for HCC were reviewed from a prospectively collected database. Outcomes of MILR were compared with those of OLR. A propensity score matching analysis with a ratio of 1:1 was performed to minimise the potential bias in clinical pathological factors...

Cirrhotic patients with severe thrombocytopenia are at increased risk of bleeding during invasive procedures. The need for preprocedural prophylaxis aimed at reducing the risk of bleeding in cirrhotic patients with thrombocytopenia who undergo scheduled procedures is assessed via the platelet count; however, establishing a minimum threshold considered safe is challenging. A platelet count ≥ 50000/μL is a frequent target, but levels vary by provider, procedure, and specific patient. Over the years, this value has changed several times according to the different guidelines proposed in the literature...

The association between octreotide and thrombocytopenia has been documented in the literature but it remains a rare finding. We are reporting a 59-year-old female patient with alcoholic liver cirrhosis who presented with the gastrointestinal tract (GIT) bleeding secondary to esophageal varices. Initial management involved fluid and blood products resuscitation and initiation of both octreotide and pantoprazole infusion. However, the abrupt onset of severe thrombocytopenia was evident within a few hours of admission...

Kounis syndrome is a multisystem and multidisciplinary disease affecting the circulatory system that can be manifested as spasm and thrombosis. It can occur as allergic, hypersensitivity, anaphylactic, or anaphylactoid reactions associated with the release of inflammatory mediators from mast cells and from other interrelated and interacting inflammatory cells, including macrophages and lymphocytes. A platelet subset with high- and low-affinity IgE surface receptors is also involved in this process. Whereas the heart, and particularly the coronary arteries, constitute the primary targets of inflammatory mediators, the mesenteric, cerebral, and peripheral arteries are also vulnerable...

INTRODUCTION: Immune dysfunction and thrombocytopenia are common features in liver cirrhosis. Platelet transfusion is the most widely used therapeutic approach for thrombocytopenia when indicated. The transfused platelets are prone to lesions during their storage that empower their interaction with the recipient leucocyte. These interactions modulate the host immune response. The impact of platelet transfusion on the immune system in cirrhotic patients is little understood. Therefore, this study aims to investigate the impact of platelet transfusion on neutrophil function in cirrhotic patients...

BACKGROUND: Chronic liver disease (CLD) related thrombocytopenia increases the risk of bleeding and poor prognosis. Many liver disease patients require invasive procedures or surgeries, such as liver biopsy or endoscopic variceal ligation, and most of them have lower platelet counts, which could aggravate the risk of bleeding due to liver dysfunction and coagulation disorders. Unfortunately, there is no defined treatment modality for CLD-induced thrombocytopenia. Recombinant human thrombopoietin (rhTPO) is commonly used to treat primary immune thrombocytopenic purpura and thrombocytopenia caused by solid tumor chemotherapy; however, there are few reports on the use of rhTPO in the treatment of CLD-related thrombocytopenia...

Advanced chronic liver disease is accompanied with relevant changes in the corpuscular and plasmatic coagulation system. Due to thrombocytopenia that is regularly observed in these patients, platelet transfusions are often performed prior invasive procedures to prevent possible bleeding complications. However, platelet transfusions are associated with clinically significant adverse events and economically relevant health care costs. Thus, avoiding unnecessary platelet transfusions remains pivotal in daily clinical practice...

Background : Gastrointestinal bleeding (GIB) is one of most frequent and significant challenges for emergency physicians and gastroenterologists. Mortality for upper (U) GIB is high, especially in the elderly and comorbid patients. However, there is scant evidence in the literature concerning an assessment of warfarin (VKA) and direct oral anticoagulants (DOACs) in terms of upper gastrointestinal bleeding (UGIB) severity. Aims : Using data from two different settings (Italy and the UK), we aimed to compare the impact of VKA and DOACs on the severity of UGIB...

RATIONALE: Lusutrombopag is a thrombopoietin receptor agonist which reduces the need for platelet transfusions before planned invasive procedures. A post hoc analysis of data from the registration trials observed that lusutrombopag-treated patients who achieved a platelet count > 50 × 109/L (responder patients) did so in a median of 6 days and the effect on platelet count lasted for nearly 3 weeks in total. Since patients with cirrhosis often require repeat invasive procedures, this kind of response-time trend sheds light on the possibility of placing more than one invasive procedure within a single course of lusutrombopag treatment...

Hemorrhagic cholecystitis is a rare diagnosis that closely mimics acute cholecystitis. Physical examination, laboratory studies and, in particular, computed tomography imaging allow for rapid diagnosis, stabilization and emergent surgical intervention. We describe our experience with three patients requiring emergent surgical intervention for hemorrhagic cholecystitis with unique clinical features including decreased platelet function due to liver cirrhosis, dual antiplatelet therapy and intraoperative finding of cholecystohepatic communication...

Transfusion-related acute lung injury (TRALI) following transfusion of all plasma-containing blood products is a rare but serious syndrome characterized by the acute onset of non-cardiogenic pulmonary edema with severe hypoxemia with or without symptoms of hypotension, pinkish frothy secretions, fever, and cyanosis. In this report, we present a case of a 66-year-old female with a medical history significant for hypertension, hyperlipidemia, hepatitis C, liver cirrhosis, tobacco use disorder, metastatic spindle cell carcinoma of the lung status post chemotherapy who developed TRALI after administration of one unit of platelets...

PURPOSE: Probing efficacy and safety of lusutrombopag in Chinese chronic liver disease (CLD) and severe thrombocytopenia (PLT < 50 × 109 /L) patients undergoing elective invasive procedures. METHODS: In this double-blind, parallel-group phase 3 study, 66 patients with CLD and severe thrombocytopenia were randomized 2:1 to lusutrombopag or placebo arm treatment regimens for seven days at 9 centers in China. Responders (PLT ≥ 50 × 109 /L that increased to ≥ 20 × 109 /L from the baseline and not received rescue therapy for bleeding) on Day 8 (the day after seven-day treatment) were assessed...

Blood transfusion, splenectomy, and partial splenic embolization (PSE) are generally performed for thrombocytopenia in patients with cirrhosis. Recently, thrombopoietin (TPO) agonists have become available, and investigations of patients who would benefit from them are necessary. Therefore, it is important to understand the fluctuations in cytokine levels associated with PSE. Therefore, fluctuations in platelet-associated immunoglobulin G (PAIgG), interleukin 6 (IL-6), and TPO levels with PSE were analyzed in this study...

Patients with cirrhosis often have abnormal hemostasis, with increased risk of hemorrhage and thrombosis. Thromboelastography provides a rapid assessment of the coagulation status and can guide product transfusions in adult patients with cirrhosis. This study aimed to determine whether the use of thromboelastography in adult patients with cirrhosis decreases blood product use and impacts adverse events or mortality compared with standard practice. A registered (PROSPERO CRD42020192458) systematic review and meta-analysis was conducted for randomized controlled trials (RCTs) comparing thromboelastography-guided hemostatic management versus standard practice (control)...

BACKGROUND: Platelet transfusion in acute variceal bleeding (AVB) is recommended by few guidelines and is common in routine clinical practice, even though the effect of thrombocytopenia and platelet transfusion on the outcomes of AVB is unclear. AIM: To determine how platelet counts, platelets transfusions, and fresh frozen plasma transfusions affect the outcomes of AVB in cirrhosis patients in terms of bleeding control, rebleeding, and mortality. METHODS: Prospectively maintained database was used to analyze the outcomes of cirrhosis patients who presented with AVB...
