-
- Myelofibrosis-Osteosclerosis (MOS) is a disorder characterized by
- proliferation of fibrous tissue in the bone marrow, causing anemia, weakness
- and fatigue due to replacement of normal bone marrow cells. Episodes of
- severe pain in the abdomen, the bones and joints also may occur.
-
- Symptoms
-
- Myelofibrosis-Osteosclerosis is characterized by the symptoms of anemia (a
- decrease of red blood cells) such as weakness, fatigue, dizziness, and
- headache. Affected persons may have ringing noises in their ears (tinnitus),
- see spots before their eyes, and suffer from drowsiness, irritability and
- sometimes bizarre behavior. Absence of menstruation in females, lack of sex
- drive, gastrointestinal (stomach and bowels) complaints, and jaundice may
- also occur. An enlarged spleen (splenomegaly) is usually present, and an
- associated enlarged liver (hepatomegaly) is common. Abdominal discomfort
- caused by pressure from the enlarged spleen may be the first complaint.
- Episodes of severe pain in the abdomen, the bones and joints are
- characteristic of this disorder.
-
- Causes
-
- A cause of Myelofibrosis which has a clinical picture similar to Agnogenic
- Myeloid Metaplasia is the spread of cancer (metastasis) to bone marrow from
- primary tumors. These tumors most often originate in the breast, prostate,
- kidney, lung, or adrenal or thyroid gland.
-
- In children a rare cause of MOS is marble-bone disease of Albers-Schonberg.
-
- Myelofibrosis-Osteosclerosis (MOS) may be a connective tissue reaction to
- several types of injury resulting in bone marrow tissue death.
-
- A secondary type of MOS is frequently associated with tuberculosis and
- with exposure to toxic substances, such as benzene, fluoride or phosphorus.
-
- Affected Population
-
- MOS affects persons of both sexes usually during mid-adult life. Children
- are rarely affected.
-
- Therapies: Standard
-
- Therapy for Myelofibrosis-Osteosclerosis involves treating the underlying
- disorder. In cases where the cause is not known, treatment is symptomatic
- and supportive. Blood transfusions are prescribed if the anemia produces
- cardiovascular symptoms. In primary myelofibrosis, moderate success has been
- obtained using male hormones (androgens) and/or corticosteroids in an attempt
- to increase red blood cell production or decrease their destruction.

- Therapies: Investigational
