Case Report: The Use of Intravenous SMOFlipid Infusion to Treat Severe Asparaginase-Induced Hypertriglyceridemia in Two Pediatric Acute Lymphoblastic Leukemia Patients.

Front Pediatr 2021 22;9:660627. Epub 2021 Apr 22.

Pediatric Hematology and Oncology Unit, Department of Pediatrics, UKM Medical Centre, Faculty of Medicine, The National University of Malaysia, Kuala Lumpur, Malaysia.

Asparaginase-induced hypertriglyceridemia can have a spectrum of clinical presentations, from being asymptomatic to having life-threatening thrombosis or hyperviscosity syndrome. At present, there is no recommendation on routine lipid monitoring during asparaginase-containing treatment phase, nor a standardized guideline on its management. Two cases are presented here to illustrate the effects of concurrent infection on asparaginase-induced hypertriglyceridemia in patients with high-risk ALL and the use of SMOFlipid infusion as a treatment option in an acute situation.

The utility of therapeutic plasma exchange in Hyperviscosity syndrome associated with juvenile rheumatoid arthritis: A case report.

J Clin Apher 2021 May 4. Epub 2021 May 4.

Department of Pathology, Division of Transfusion Medicine and Hemostasis, University of Texas Southwestern Medical Center, Dallas, Texas, USA.

Hyperviscosity syndrome (HVS) is a life-threatening syndrome caused by high concentrations of large plasma proteins like IgM, rheumatoid factor, and other immune complexes, leading to increased blood viscosity and symptoms such as visual abnormalities, neurological impairment, bleeding diathesis, and thrombosis. While Waldenström's macroglobulinemia accounts for 80% to 90% of cases, HVS may develop in other clinical settings characterized by elevations in plasma proteins. Limited evidence currently exists describing the safety and efficacy of therapeutic plasma exchange (TPE) for the management of HVS secondary to non-neoplastic conditions. Read More

Successful Treatment of Pediatric Inflammatory Multisystem Syndrome Temporally Associated with COVID-19 (PIMS-TS) with Split Doses of Immunoglobulin G and Estimation of PIMS-TS Incidence in a County District in Southern Germany.

Healthcare (Basel) 2021 Apr 18;9(4). Epub 2021 Apr 18.

Department of Pediatrics, Hospital Ostallgäu-Kaufbeuren, 87600 Kaufbeuren, Germany.

Pediatric inflammatory multisystem syndrome temporally associated with SARS Cov2 (PIMS-TS) is a newly encountered disease in children sharing clinical features with Kawasaki disease, toxic shock syndrome, or macrophage-activating syndrome. Pathogenically, it is associated with immune-mediated post-infectious hyperinflammation leading to short-term myocardial injury with yet unknown long-term outcome. We herein present three cases of PIMS-TS treated in our institution with divided doses of immunoglobulins and high dose acetyl salicylic acid, according to existing Kawasaki disease guidelines.

Polyclonal hypergammaglobulinaemia: assessment, clinical interpretation, and management.

Lancet Haematol 2021 May;8(5):e365-e375

Division of Hematology, University of British Columbia, Vancouver, BC, Canada; Centre for Health Education Scholarship, University of British Columbia, Vancouver, BC, Canada; Department of Medicine, Vancouver General Hospital, Vancouver, BC, Canada. Electronic address:

This Review outlines a practical approach to assessing and managing polyclonal hypergammaglobulinaemia in adults. Polyclonal hypergammaglobulinaemia is most commonly caused by liver disease, immune dysregulation, or inflammation, but can also provide an important diagnostic clue of rare diseases such as histiocyte disorders, autoimmune lymphoproliferative syndrome, Castleman disease, and IgG4-related disease. Causes of polyclonal hypergammaglobulinaemia can be divided into eight categories: liver disease, autoimmune disease and vasculitis, infection and inflammation, non-haematological malignancy, haematological disorders, IgG4-related disease, immunodeficiency syndromes, and iatrogenic (from immunoglobulin therapy).

Reflections on the unexpected laboratory finding of hemorheological alterations observed in some haematological disorders.

Microvasc Res 2021 Apr 20;136:104171. Epub 2021 Apr 20.

Department of Health Promotion and Child Care, Internal Medicine and Medical Specialties, Università degli Studi di Palermo, Palermo, Italy. Electronic address:

Hyperviscosity syndrome is a clinical condition characterized by the slowing of blood flow through the vessels and it may be associated with several diseases. The nosographic classification of primary hyperviscosity conditions (Wells classification 1970) divided the primary hyperviscosity syndromes in polycythaemic, sclerocytemic and sieric. Recent and personal laboratory observations have highlighted an unexpected behaviour of the erythrocyte deformability observed in some haematological disorders such as polycythemia vera, multiple myeloma and monoclonal gammopathy of undetermined significance.

Int Heart J 2020 Nov 13;61(6):1289-1293. Epub 2020 Nov 13.

Department of Cardiology, Saitama Medical University International Medical Center.

Essential thrombocythemia (ET) is a Philadelphia chromosome-negative myeloproliferative disorder that is characterized by the overproduction of platelets and a marked increase in the numbers of mature megakaryocytes present in the bone marrow. Thrombohemorrhagic disorders are major morbidities of ET, especially those with mutations in the gene encoding Janus kinase 2 (JAK2). In this study, we report the case of an 18-year-old patient with ET carrying JAK2 mutation who developed acute ST-elevation myocardial infarction (STEMI) 5 months after a commencement of anagrelide.

Saudi J Biol Sci 2021 Jan 5;28(1):956-961. Epub 2020 Nov 5.

Department of Clinical Laboratory Sciences, College of Applied Medical Sciences, Imam AbdulRahman bin Faisal University, P.O. Box: 1982, Dammam 31441, Saudi Arabia.

The coronavirus disease (COVID-19), which is also known as acute respiratory syndrome coronavirus-2 (SARS-CoV2) is a transmissible disease, has phenotypes varying from asymptomatic to Acute Respiratory Distress Syndrome (ARDS) or multiple organ dysfunction syndrome (MODS) and ultimately death in certain cases. Coagulation disorders are being frequently reported amongst these patients and the pathogenesis is still not completely understood. Proposed mechanisms for these coagulopathies comprise a hypercoagulable state with micro- and/or macro-thrombosis in the vessels. Read More

UNC Department of Family Medicine, 590 Manning Drive, Chapel Hill, NC 27599.

Multiple myeloma (MM) is a malignancy of bone marrow plasma cells that produce abnormal immunoglobulins. It is the second most common hematologic cancer and typically is diagnosed in individuals ages 65 to 74 years. MM is the final stage in a continuum that starts with monoclonal gammopathies of undetermined significance (MGUS), a premalignant condition characterized by production of abnormal immunoglobulins.

Department of China Military Institute of Chinese Materia, The Fifth Medical Centre, Chinese PLA (People's Liberation Army) General Hospital, Beijing, 100039, China. Electronic address:

Ethnopharmacological Relevance: Hyperviscosity syndrome (HVS) is a major risk factor for thrombotic diseases. Rhubarb, well-known as a traditional Chinese medicine, exhibits multiple pharmacological activities, especially for promoting blood circulation to remove blood stasis (PBRB), which has been become a functional health food for decreasing the risk of cardiovascular diseases. However, due to the complexity of rhubarb components, it is still difficult to clarify the specific targets of effective substances in PBRB, and the pharmacodynamic mechanism needs to be further probed.

Department of Psychiatry, Iqraa International Hospital and Research Centre, Calicut, Kerala, India.

Waldenstrom's macroglobulinemia (WM) is a rare and slowly progressive disorder, a variant of lymphoplasmacytic lymphoma, which needs therapy only when patient becomes symptomatic. WM presents usually with constitutional symptoms, organomegaly, cytopenias, and hyperviscosity syndrome. This neoplasm is composed of small lymphocytes, plasmacytoid lymphocytes, and plasma cells that typically involve the bone marrow, and it is associated with an immunoglobulin M (IgM) gammopathy.
