Accuracy of Diagnosing Heparin-Induced Thrombocytopenia.

Importance: Heparin-induced thrombocytopenia (HIT) is a life-threatening condition that requires urgent diagnostic clarification. However, knowledge of the diagnostic utility of the recommended diagnostic tests is limited in clinical practice.

Objective: To evaluate the current diagnostic practice for managing the suspicion of HIT.

Zoledronic Acid Does Not Retard Bone Union: A Randomized Controlled Trial in Fragility Intertrochanteric Femur Fractures.

Background: Fragility hip fracture is a leading cause of death in the elderly and is common in postmenopausal women and elderly people. In the treatment of osteoporosis, bisphosphonates (BPs) are often considered first-line medications. Zoledronic acid is the most potent and long-acting BP in clinical use and is administered as an intravenous infusion.

COVID-19 vaccination associated severe immune thrombocytopenia.

Background: Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 has emerged as a deadliest global pandemic after its identification in December 2019 in Wuhan, China resulting in more than three million deaths worldwide. Recently FDA issued emergency authorization for three vaccines for prevention of COVID-19. Here in, we report three cases of severe immune thrombocytopenia (ITP) following COVID-19 vaccination and their clinical course.

Incidence of Skin and Respiratory Immune-Related Adverse Events Correlates With Specific Tumor Types in Patients Treated With Checkpoint Inhibitors.

Checkpoint inhibitors (CPIs) increase antitumor activity by unblocking regulators of the immune response. This action can provoke a wide range of immunologic and inflammatory side effects, some of which can be fatal. Recent studies suggest that CPI-induced immune-related adverse events (irAEs) may predict survival and response.

International survey on Helicobacter pylori testing in patients with immune thrombocytopenia: Communication of the platelet immunology scientific and standardization committee.

Essentials When to test and treat H pylori among patients with ITP is controversial. We report the results of an international survey administered to physicians with experience treating ITP across 39 countries. The decision to test for H pylori was influenced by country, country of origin, and concomitant gastrointestinal symptoms.

Perioperative oral eltrombopag versus intravenous immunoglobulin in patients with immune thrombocytopenia: a non-inferiority, multicentre, randomised trial.

Background: Patients with immune thrombocytopenia are at risk of bleeding during surgery, and intravenous immunoglobulin is commonly used to increase the platelet count. We aimed to establish whether perioperative eltrombopag was non-inferior to intravenous immunoglobulin.

Methods: We did a randomised, open-label trial in eight academic hospitals in Canada.

Cost Analysis of R-CHOP Dose-Adjusted R-EPOCH in Treatment of Diffuse Large B-Cell Lymphoma with High-Risk Features.

Dose-adjusted rituximab, etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin (DA.R-EPOCH) is used for upfront treatment of high-risk diffuse large B cell lymphoma (DLBCL). In this study, we compared the outcomes in patients with high-risk DLBCL who received frontline rituximab, cycophosphamide, doxorubicin, vincristine, prednisone (R-CHOP) or DA.

Timeliness of Initial Therapy in Multiple Myeloma: Trends and Factors Affecting Patient Care.

Multiple myeloma (MM) treatment has advanced significantly over the last 2 decades. In most patients, the disease course has been altered from early fatality to chronic morbidity with multiple lines of treatment. The MM treatment paradigm has shifted toward treating patients before end-organ damage occurs.

Quality Initiative in Clinical Practice: A Single-Institution Appraisal of Quality Metrics in the Management of Newly Diagnosed Diffuse Large B-Cell Lymphoma.

Objective: To assess our adherence to treatment guidelines for diffuse large B-cell lymphoma (DLBCL) established by the American Society of Hematology in 2014 through implementation of a quality improvement initiative (QII) at our institution in 2015.

Patients And Methods: Patients with newly diagnosed DLBCL treated from January 1, 2006, through December 31, 2017, were identified. Electronic medical records were reviewed for documentation of American Society of Hematology Practice Improvement Module quality measures (eg, key pathologic features of DLBCL, lymphoma staging, and screening for hepatitis B virus [HBV] infection in patients receiving rituximab-based chemotherapy).

Elevated Neutrophil-Lymphocyte Ratio is Predictive of Poor Outcomes Following Aneurysmal Subarachnoid Hemorrhage.

Background Recent studies of patients with intracerebral hemorrhage suggest an association between peripheral blood neutrophil-lymphocyte ratio and neurologic deterioration. We aimed to study the prognostic utility of neutrophil-lymphocyte ratio in predicting inpatient mortality in aneurysmal subarachnoid hemorrhage. Methods We conducted a retrospective electronic medical record review of the clinical, laboratory, and radiographic data of patients with aneurysmal subarachnoid hemorrhage 18 years of age or older presenting to the neuroscience intensive care unit from January 1, 2011, to December 31, 2017.

B-cell acute lymphoblastic leukemia in an elderly man with plasma cell myeloma and long-term exposure to thalidomide and lenalidomide: a case report and literature review.

Background: The advent of the immunomodulatory imide drugs (IMiDs) lenalidomide and thalidomide for the treatment of patients with plasma cell myeloma (PCM), has contributed to more than a doubling of the overall survival of these individuals. As a result, PCM patients join survivors of other malignancies such as breast and prostate cancer with a relatively new clinical problem - second primary malignancies (SPMs) - many of which are a result of the treatment of the initial cancer. PCM patients have a statistically significant increased risk for acute myeloid leukemia (AML) and Kaposi sarcoma.

Sequence of Splenectomy and Rituximab for the Treatment of Steroid-Refractory Immune Thrombocytopenia: Does It Matter?

Objective: To evaluate the impact of the sequence of treatment with rituximab and/or splenectomy on time to relapse for patients with steroid-refractory immune thrombocytopenia (ITP).

Patients And Methods: Patients 18 years or older with steroid-refractory immune thrombocytopenia who underwent treatment with splenectomy or rituximab from January 1, 2002, through December 31, 2015, at Mayo Clinic. Evaluation included freedom from relapse (FFR) and response rates after treatment with rituximab or splenectomy as single or sequential interventions.

Apixaban and dalteparin in active malignancy-associated venous thromboembolism: The ADAM VTE trial.

Background: Low-molecular-weight heparin is the guideline-endorsed treatment for cancer-associated venous thromboembolism (VTE). While apixaban is approved for the treatment of acute VTE, limited data support its use in cancer patients.

Objectives: The primary outcome was major bleeding.

Trends in the risk of second primary malignancies among survivors of chronic lymphocytic leukemia.

With improving survivorship in chronic lymphocytic leukemia (CLL), the risk of second primary malignancies (SPMs) has not been systematically addressed. Differences in risk for SPMs among CLL survivors from the Surveillance, Epidemiology, and End Results (SEER) database (1973-2015) were compared to risk of individual malignancies expected in the general population. In ~270,000 person-year follow-up, 6487 new SPMs were diagnosed with a standardized incidence ratio (SIR) of 1.

Etiologies of Extreme Thrombocytosis: A Contemporary Series.

Objective: To describe the multifactorial etiologies of extreme thrombocytosis (EXT) in different care settings and the frequency of finding an occult malignancy.

Patients And Methods: We conducted a retrospective chart review at Mayo Clinic from January 1, 2011, through December 31, 2016. Adult patients who had at least 2 readings of platelet counts greater than 1000×10/L within 30 days of each other were included.

Survival Trends in Young Patients With Multiple Myeloma: A Focus on Racial-Ethnic Minorities.

Introduction: Outcomes in multiple myeloma (MM) have improved significantly over time. This is true overall for all patients as well as patient subgroups based on age and race/ethnicity. Despite this, disparities are noted in outcomes when looking at racial subgroups.

Hepatic iron overload identified by magnetic resonance imaging-based T2* is a predictor of non-diagnostic elastography.

Background: Magnetic resonance elastography (MRE) is a non-invasive test used to assess liver stiffness and fibrosis in chronic liver disease, which includes systemic iron overload. However, iron deposition by itself is associated with technical failure of MRE of the liver which necessitates the use of invasive liver biopsy as an alternative monitoring method for these patients. T2*-weighted magnetic resonance imaging (T2*) is a reliable modality to asses for hepatic as well as total body iron overload.

Hypereosinophilia in a patient with metastatic non-small-cell lung cancer treated with antiprogrammed cell death 1 (anti-PD-1) therapy.

Immune checkpoint inhibitors have changed the treatment paradigm for patients with cancer. Though a majority of patients tolerate treatment, some develop hematologic toxicities, including eosinophilia. Eosinophilia has been associated with better responses in some patients with melanoma, but this has not been investigated in non-small-cell lung cancer.

Management of Helicobacter pylori in Patients with Immune Thrombocytopenia.

There is an association between infection and immune thrombocytopenia (ITP), and few studies have suggested that eradicative treatment of infection may improve platelet counts in patients with ITP. Conventional treatments for ITP include immunosuppressive agents, and more recently thrombopoietic agents. However, based on clinical reports of association between and ITP, several medical societies increasingly suggest detection and eradication of as a treatment for ITP.

Myelodysplasia-related acute myeloid leukemia and acute promyelocytic leukemia: concomitant occurrence of two molecularly distinct diseases.

Concurrent presentation of acute promyelocytic leukemia (APL) with other hematologic diseases in the absence of previous chemotherapy or ionizing radiotherapy treatment is very rare. We present a case of simultaneous occurrence of APL with myelodysplastic syndrome (MDS)-related acute myeloid leukemia (AML). A 43-yearold female presented with 3 month of history fatigue, night sweats, chills and pancytopenia.
