Murine bone marrow mesenchymal stromal cells have reduced hematopoietic maintenance ability in sickle cell disease.

Blood 2021 Jul 30. Epub 2021 Jul 30.

New York Blood Center, New York, New York, United States.

Sickle Cell Disease (SCD) is characterized by hemolytic anemia, which can trigger oxidative stress, inflammation, and tissue injury that contributes to disease complications. Bone marrow mesenchymal stromal cells (MSCs) tightly regulate hematopoietic stem cell (HSC) homeostasis in health and disease but their functionality in SCD remains unclear. We identified for the first time murine SCD MSCs to have altered gene signatures, reduced stem cell properties, and increased oxidative stress, due in part to hemolysis. Read More

Hyperhomocysteinemia-related lung disease and hemolytic anemia with bone marrow features masquerading as myelodysplasia.

Am J Blood Res 2021 15;11(3):266-270. Epub 2021 Jun 15.

Department of Laboratory Medicine, Uji-Tokushukai Medical Center Uji, Kyoto, Japan.

Hyperhomocysteinemia is linked to TMA-related clinical symptoms such as apparent thromboembolism, microangiopathic hemolytic anemia (MAHA), and various types of end-organ damage due to microvascular thrombi; this is because high plasma levels of homocysteine impair the vascular endothelium. However, the association between hyperhomocysteinemia and pulmonary involvement is unclear. Here, we describe a 63-year-old male who was hospitalized with respiratory failure and MAHA with MDS-like features in the bone marrow. Read More

Subglottic concretion masquerading as foreign body in a child with β thalassemia major: an airway nightmare!

BMJ Case Rep 2021 Jul 26;14(7). Epub 2021 Jul 26.

Pathology, Army Hospital Research and Referral, New Delhi, India.

Subglottic concretion is a rare and perilous condition usually presenting with existing or impending airway obstruction. Due to long-standing nature of the condition, slow progression of symptoms and rarity of occurrence, the condition is either missed or misdiagnosed. Its resemblance in presentation and symptoms to that of foreign body (FB) bronchus can lead to a diagnostic misadventure. Read More

A Sri Lankan girl with a new genetic variant in the PKLR gene causing pyruvate kinase deficiency: a case report.

J Med Case Rep 2021 Jul 27;15(1):374. Epub 2021 Jul 27.

Department of Molecular Pathology, Viapath at King's College Hospital, King's College Hospital, London, SE5 9RS, UK.

Background: Erythrocyte pyruvate kinase is expressed under the control of the PKLR gene located on chromosome 1q21. Pyruvate kinase catalyzes the final steps of the glycolytic pathway and creates 50% of the red cell total adenosine triphosphate. Pyruvate kinase deficiency is the commonest glycolytic defect causing congenital non-spherocytic hemolytic anemia inherited in an autosomal recessive trait in which homozygotes and compound heterozygotes are common.

Diagnostic sensitivity of extended renal and hematologic criteria to define hemolytic uremic syndrome.

Arch Argent Pediatr 2021 Aug;119(4):238-244

Unidad de Nefrología, Hospital General de Niños "Dr. Pedro de Elizalde", Ciudad Autónoma de Buenos Aires, Argentina.

Introduction: The usual definition of Shiga toxin-producing Escherichia coli hemolytic uremic syndrome (STEC-HUS) is based on the presence of anemia, thrombocytopenia, and elevated serum creatinine levels, with or without proteinuria and/or hematuria. The strict definition only considers elevated serum creatinine levels as a renal criterion. The extended definition maintains flexible renal criteria, although it replaces anemia with hemolysis and considers a sharp drop in platelet count as an indicator of platelet consumption. Read More

Transplant-associated thrombotic microangiopathy: elucidating prevention strategies and identifying high-risk patients.

Expert Rev Hematol 2021 Jul 23. Epub 2021 Jul 23.

Division of Bone Marrow Transplantation and Immune Deficiency, Cancer and Blood Disease Institute, Cincinnati Children's Hospital Medical Center, Cincinnati, OH, USA.

Introduction: : Hematopoietic stem cell transplantation-associated thrombotic microangiopathy (TA-TMA) is a severe complication of transplant. TA-TMA is a multifactorial disease where generalized endothelial dysfunction leads to microangiopathic hemolytic anemia, intravascular platelet activation, and formation of microthrombi leading to end-organ injury. It is essential to identify patients at risk for this complication and to implement early interventions to improve TA-TMA associated transplant outcomes. Read More

Common Variable Immunodeficiency and Autoimmune Diseases: A Retrospective Study of 95 Adult Patients in a Single Tertiary Care Center.

Front Immunol 2021 5;12:652487. Epub 2021 Jul 5.

Department of Translational Medical Sciences, University of Naples Federico II, Naples, Italy.

Common variable immunodeficiency (CVID) is the most common clinically significant primary immunodeficiency in adulthood, which presents a broad spectrum of clinical manifestations, often including non-infectious complications in addition to heightened susceptibility to infections. These protean manifestations may significantly complicate the differential diagnosis resulting in diagnostic delay and under-treatment with increased mortality and morbidity. Autoimmunity occurs in up to 30% of CVID patients, and it is an emerging cause of morbidity and mortality in this type of patients. Read More

The wide spectrum of β-thalassaemia intermedia-induced pulmonary hypertension: two case reports on the possible role of specific pulmonary arterial hypertension therapy.

Pulm Circ 2021 Jul-Sep;11(3):20458940211030490. Epub 2021 Jul 6.

2nd Department of Critical Care and Pulmonary Hypertension Clinic, National & Kapodistrian University of Athens, Attikon Hospital, Athens, Greece.

Pulmonary hypertension (PH) development remains a significant cardiovascular complication of haemoglobinopathies, severely affecting the morbidity and mortality of such patients. According to the 5th World Symposium on PH, PH related with chronic haemolytic anaemias is classified in group 5, mainly due to the multifactorial pathophysiology of PH in this patient population. There are no clear guidelines regarding the management of PH in patients with haemoglobinopathies; the use of specific pulmonary arterial hypertension (PAH) therapy in patients with β-thalassaemia and PH is based on data derived from other forms of PH, expert opinion and small series or case reports.
