Patients with multiple myeloma are at an increased risk of venous thromboembolism (VTE), especially when treated with the immunomodulatory drugs, thalidomide and lenalidomide, in combination with dexamethasone and/or chemotherapy. Several studies have shown that patients with multiple myeloma precursor disease (monoclonal gammopathy of undetermined significance [MGUS]) also have a higher risk of thrombosis compared to the general population. The underlying mechanisms for the hypercoagulable state are not completely understood. In this review, we discuss risk factors for thrombosis in multiple myeloma, as well as prophylactic strategies, the evidence for thrombosis among patients with MGUS, and proposed mechanisms for the hypercoagulability.

Differentiation of Common Myeloid Progenitor Cells

Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

Multipotency of Hematopoietic Stem Cells

The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...
