Arteritis is the inflammation of the walls of arteries, usually as a result of infection or autoimmune response. Arteritis, a complex disorder, is still not entirely understood. Arteritis may be distinguished by its different types, based on the organ systems affected by the disease. A complication of arteritis is thrombosis, which can be fatal. Arteritis and phlebitis are forms of vasculitis. Signs and Symptoms
Symptoms of general arteritis may include:
Inflammation
Fever
Increased production of red blood cells (erythrocytes)
Limping
Reduced pulse

Diagnosis
Diagnosis of arteritis is based on unusual medical symptoms. Similar symptoms may be caused by a number of other conditions, such as Ehlers-Danlos syndrome and Marfan syndrome (both heritable disorders of connective tissue), tuberculosis, syphilis, spondyloarthropathies, Cogans syndrome, Buergers, Behcets, and Kawasaki disease. Various imaging techniques may be used to diagnose and monitor disease progression. Imaging modalities may include direct angiography, magnetic resonance angiography, and ultrasonography.Angiography is commonly used in the diagnosis of Takayasu arteritis,  especially in the advanced stages of the disease, when arterial stenosis, occlusion, and aneurysms may be observed. However, angiography is a relatively invasive investigation, exposing patients to large doses of radiation, so is not recommended for routine, long-term monitoring of disease progression in patients with Takayasu arteritis.Computed tomography angiography can determine the size of the aorta and its surrounding branches, and can identify vessel wall lesions in middle to late stages of arteritis. CTA can also show the blood flow within the blood vessels.
Idarubicin  or 4-demethoxydaunorubicin is an anthracycline antileukemic drug. It inserts itself into DNA and prevents DNA unwinding by interfering with the enzyme topoisomerase II. It is an analog of daunorubicin, but the absence of a methoxy group increases its fat solubility and cellular uptake. Similar to other anthracyclines, it also induces histone eviction from chromatin.It belongs to the family of drugs called antitumor antibiotics. It is currently combined with cytosine arabinoside as a first line treatment of acute myeloid leukemia. It is used for treatment of acute lymphoblastic leukemia and chronic myelogenous leukemia in blast crisis.It is distributed under the trade names Zavedos (UK) and Idamycin (USA). Side effects
Diarrhea, stomach cramps, nausea and vomiting are common among patients treated with idarubicin. References
