Project description:Nonbacterial thrombotic endocarditis (NBTE) is characterized by the deposition of thrombi on the heart valves without bacteremia and predominantly affects patients with hypercoagulable state. Since the lesion of NBTE often exists in the left-sided valves, involvement of the tricuspid valve (TV) is rare. We herein report a 34-year-old woman with advanced ovarian cancer and pulmonary embolization showing NBTE on the TV. Plasma D-dimer level was markedly elevated and echocardiography showed highly mobile masses on the TV with moderate to severe regurgitation. After the initiation of heparin therapy, reduction of plasma D-dimer levels along with shrinkage of the TV vegetations was observed. However, she was forced to discontinue the heparin because its supply was interrupted in association with coronavirus disease 2019. Coupled with systemic metastasis of ovarian cancer, elevated plasma D-dimer level and exacerbation of NBTE were observed. Thereafter, she resumed subcutaneous injection of heparin, resulting in re-improvement.Learning objectiveInvolvement of tricuspid valve (TV) by nonbacterial thrombotic endocarditis (NBTE) is rare, especially when they are associated with advanced cancer. Our case underlines the importance of listing the NBTE as a differential diagnosis in cancer patients showing valve vegetations even in the TV.

Project description:Sepsis is frequently complicated by coagulopathy and, in about 35 % of severe cases, by disseminated intravascular coagulation (DIC). In Japan, aggressive treatment of septic DIC is encouraged using antithrombin and recombinant thrombomodulin. The macrophages, monocytes, and neutrophils are a source of TF and participate in the direct activation of the coagulation cascade in the early phases of sepsis. And activated factor X (FXa), which is involved in hemostasis, thrombogenesis, inflammation, and cellular immune responses, induces TF expression in human peripheral monocytes and, conversely, that inhibition of FXa activity reduces TF expression. Both inflammation and coagulation play an important role in DIC due to sepsis. In addition to inflammatory cytokines (TNF-α, IL-1 and so on), HMGB1 has recently been shown to mediate the lethal late phase of sepsis and caused coagulopathy. TM not only binds HMGB1 but also aids the proteolytic cleavage of HMGB1 by thrombin. There have been many reports of the efficacy of recombinant TM and antithrombin for treatment of septic DIC from Japan. Further investigation of the efficacy of recombinant TM and AT in countries other than Japan, as well as the monitoring of medical costs incurred during hospitalization, will help validate the use of TM and AT for treatment of septic DIC.

Project description:IntroductionSince disseminated intravascular coagulation (DIC) was first described, it has been considered a serious disease of the coagulation system and a major challenge to clinicians. Currently, several important knowledge gaps remain. The DANish Disseminated Intravascular Coagulation (DANDIC) Cohort Study will aim to answer questions regarding the incidence and mortality of patients with DIC including time trends. The study will also identify prognostic factors that may guide personalised prevention and treatment. Furthermore, the study will describe treatment patterns and the safety and effectiveness of various treatment modalities.Methods and analysisWe will establish the DANDIC Cohort using data collected in daily clinical practice from the Central Denmark Region, which covers approximately 1.3 million residents. The study period will encompass 1 January 2011 through 1 July 2021. Potential DIC cases will be identified from the hospital laboratory database, based on coagulation biomarkers, and diagnoses will be adjudicated by medical experts. The dataset will be enriched with detailed clinical data from electronic medical charts on aetiologies, bleeding, microthrombus formation, organ failure, thrombosis, treatments and comorbidities. The dataset will also take advantage of in-hospital data with longitudinal information on laboratory records, transfusions, microbiology and treatments. It will be possible to merge this dataset with other unique Danish health registries with more than 10 years of virtually complete follow-up. The project will use state-of-the-art epidemiological and biostatistical methods.Ethics and disseminationThe project has been approved by the Danish Patient Safety Authority (31-1521-452), the Central Denmark Region (1-45-70-83-21), the Danish Data Protection Agency (1-16-02-258-21) and all the hospital chairs. Register-based studies require no ethical approval in Denmark. The results will be disseminated in international peer-reviewed journals.

Project description:BackgroundNonbacterial thrombotic endocarditis (NBTE) is a rare manifestation of a number of systemic diseases, which include advanced malignancy and hypercoagulable states.Case summaryWe present a 67-year-old woman who had presented with chest pain and heart failure. Eight years ago, she had a successful Whipple resection for pancreatic adenocarcinoma. Echocardiography revealed mitral valve vegetations with negative blood cultures. She had multiple infarcts in the kidney, spleen, and brain. She was found to have a mass in the left 8th rib, consistent with metastatic pancreatic adenocarcinoma on biopsy. Ultimately, a diagnosis of NBTE was made after excluding other causes for her presentation. Because of her general poor condition, she expressed the wish for palliative care and later died 28 days after presentation.DiscussionThis case illustrates the possibility of NBTE in patients successfully treated for pancreatic adenocarcinoma and highlights the consideration of this relatively rare differential in patients with a previously treated malignancy presenting with heart failure.

Project description:BackgroundBoth disseminated intravascular coagulation and thrombotic microangiopathy are complications of sepsis as Salmonella septicemia, respectively. They are related and have similar clinical characteristics as thrombopenia and organ dysfunctions. They rarely co-occur in some specific cases, which requires a clear distinction.Case presentationA 22-year-old woman had just undergone intracranial surgery and suffered from Salmonella derby septicemia with multiorgan involvement in the hospital. Laboratory workup demonstrated coagulation disorder, hemolytic anemia, thrombocytopenia, and acute kidney injury, leading to the co-occurrence of disseminated intravascular coagulation and secondary thrombotic microangiopathy. She received antibiotics, plasma exchange therapy, dialysis, mechanical ventilation, fluids, and vasopressors and gained full recovery without complications.ConclusionDisseminated intravascular coagulation and secondary thrombotic microangiopathy can co-occur in Salmonella derby septicemia. They should be treated cautiously in diagnosis and differential diagnosis. Thrombotic microangiopathy should not be missed just because of the diagnosis of disseminated intravascular coagulation. Proper and timely identification of thrombotic microangiopathy with a diagnostic algorithm is essential for appropriate treatment and better outcomes.

Project description:The use of cardiac pacemakers is increasing worldwide. Infective endocarditis from a pacemaker lead is a rare, but one of the most severe complications of pacemaker insertion. The diagnosis of pacemaker-related infective endocarditis is usually delayed due to unspecific clinical signs and symptoms at presentation compared to native valve infective endocarditis. Several factors can increase the risk of cardiac pacemaker-related infective endocarditis including cachexia, malignancy, diabetes mellitus, immunosuppression and corticosteroid treatment. This case report is about a 70-year-old diabetic male who presented to the emergency department with disseminated intravascular coagulation (DIC), cardiac and liver failure. He was diagnosed with pacemaker infective endocarditis, which was ultimately fatal.

Project description:We describe the case of a 43-year-old woman with transient ischemic neurologic deficits and recurrent systemic and pulmonary emboli in whom infectious work-up and extensive thrombophilic evaluation were unremarkable. Transesophageal echocardiography (TEE) established the diagnosis of nonbacterial thrombotic endocarditis (NBTE). This is a rare condition often associated with hypercoagulable states or advanced malignancy such as adenocarcinomas, characterized by cardiac vegetations along valvular coaptation lines without destruction of leaflets. In our patient, we diagnosed an ovarian clear cell adenocarcinoma, a malignant disorder that has been rarely reported in association with NBTE. This case illustrates that NBTE can present as an atypical manifestation of malignancy and must be distinguished from infective endocarditis, which implies a different therapeutic strategy. When confronted with findings of NBTE without a clear etiology, an occult neoplasm must be excluded. Anticoagulant therapy is the mainstay of treatment. However, cardiac vegetations may require surgical intervention in rare instances.
