paroxysmal nocturnal hemoglobinuria symptoms

Table 1. Paroxysmal nocturnal hemoglobinuria (PNH) is a rare disease that presents clinically with a variety of symptoms, the most prevalent of which are hemolytic anemia, hemoglobinuria, and somatic symptoms including fatigue and shortness of breath. The disorder affects red blood cells (erythrocytes), which carry oxygen; white blood cells (leukocytes), which protect the body from infection; and platelets (thrombocytes), which are involved in blood clotting. Causes People with this disease have blood cells that are missing a gene called PIG-A. Learn more. Paroxysmal nocturnal hemoglobinuria, or PNH, is a rare blood disease characterized by the destruction of red blood cells as well as blood clots and impaired bone marrow function. Paroxysmal nocturnal hemoglobinuria (PNH) is a complement-driven hemolytic anemia resulting from the clonal expansion of stem cells harboring a somatic PIGA mutation. Symptoms of the disease are caused by: Hematopoietic stem cells are created in the bone marrow, the spongy center of the long bones of the body. Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, acquired, life-threatening disease of the blood characterized by destruction of red blood cells by the complement system, a part of the body's innate immune system.This destructive process occurs due to the presence of defective surface protein DAF on the red blood cell, which normally function to inhibit such immune reactions.
