Paroxysmal nocturnal haemoglobinuria [marchiafava-micheli] - what does this mean
Paroxysmal nocturnal haemoglobinuria (pnh) is a rare, acquired, life-threatening blood disorder caused by a genetic defect in the stem cells of the bone marrow. it is characterized by the destruction of red blood cells, leading to anemia, clotting problems, and organ damage. the destruction of red blood cells is caused by the activation of the complement system in the blood, which is triggered by the presence of a specific protein, cd55, which is absent in pnh cells.
What happens during the disease - paroxysmal nocturnal haemoglobinuria [marchiafava-micheli]
Paroxysmal nocturnal haemoglobinuria (pnh) is a rare, acquired, life-threatening disorder caused by a defect in the gpi-anchored proteins on the surface of red blood cells. this defect leads to an increased susceptibility to complement-mediated lysis of red blood cells, resulting in anemia, thrombosis, and organ damage due to the release of hemoglobin and other cell components into the bloodstream. in addition, the lack of gpi-anchored proteins on the cell surface can lead to impaired phagocytosis, resulting in increased susceptibility to infection.
Treatment and Medical Assistance
Main goal of the treatment: To reduce the amount of blood cell destruction and improve the patient's quality of life.
- Treat underlying conditions that may be causing the destruction of blood cells, such as infections, autoimmune disorders, or certain medications.
- Administer medications to suppress the body’s immune system, such as corticosteroids, cyclosporine, or azathioprine.
- Prescribe a medication to reduce the production of red blood cells, such as hydroxyurea.
- Administer a blood transfusion to replace red blood cells.
- Perform a stem cell transplant to replace the destroyed blood cells.
- Prescribe medications to prevent blood clots, such as anticoagulants.
- Provide lifestyle advice on how to manage the disease, such as avoiding certain foods or taking iron supplements.
