General Discussion

POEMS syndrome is an extremely rare multisystem disorder. POEMS is an acronym that stands for (P)olyneuropathy, disease affecting many nerves; (O)rganomegaly, abnormal enlargement of an organ; (E)ndocrinopathy, disease affecting certain hormone-producing glands that help to regulate the rate of growth, sexual development, and certain metabolic functions (endocrine system); (M)onoclonal gammopathy or M proteins; and (S)kin defects. Common symptoms include progressive weakness of the nerves in the arms and legs, an abnormally enlarged liver and/or spleen (hepatosplenomegaly), abnormally darkening of the skin (hyperpigmentation) and excessive hair growth (hypertrichosis). Endocrine abnormalities such as failure of the ovaries and testes (gonads) to function properly (primary gonadal failure) and diabetes mellitus type I may be present. Specific endocrine abnormalities associated with POEMS syndrome vary from case to case. Other important features of the disease include swelling around the optic nerve (papilledema), abnormal fluid retention, which may occur in the ankles (edema), the abdominal cavity (ascites), or around the lungs (pleural effusions), painless scars on bone x-ray (osteosclerosis), and an elevated platelet count (a blood cell responsible for clotting). Some patients may also have abnormalities in the lung function tests, which may not be noticed because of their inability to walk well due to their neuropathy.

POEMS syndrome is associated with a group of disorders known as monoclonal gammopathies or plasma cell dyscrasias. These disorders are characterized the uncontrolled growth of a single clone (monoclonal) of plasma cells, which results in the abnormal accumulation of M-proteins (also known as immunoglobulin M or IgM) in the blood. M-proteins are supposed to fight foreign substances in the body such as viruses and bacteria, but researchers suspect that they play a role in the development of POEMS syndrome. However, the specific role M-proteins play and the exact cause of POEMS syndrome is unknown. Research would suggest that a chemical called VEGF (vascular endothelial growth factor) plays an important role in this disease.
