Types of Peripheral Neuropathy - Inflammatory


Vasculitis is an inflammation of the blood vessel system, which includes the veins, arteries, and capillaries. Vasculitis may affect blood vessels of any type, size, or location, and therefore can cause dysfunction in any organ system, including the central and peripheral nervous system. Peripheral neuropathy may occur as a result of having vasculitis.

Vasculitis can be caused by infection of the blood vessel walls or an immune or "allergic" reaction in the vessel wall. The first cause is rare. When it occurs, bacteria, viruses or fungi infect the blood vessel. White blood cells move in to destroy the infectious agents and damage the blood vessel in the process. This is a serious condition and requires prompt antibiotic treatment.

The second cause of vasculitis, an immune reaction, is more common. Substances that cause allergic relations are called "antigens." They cause the body to make proteins called "antibodies" which bind to the antigen for the purpose of getting rid of it. Antigen and antibody bound together are called "immune complexes." Two primary ways in which immune complexes destroy antigens are by attracting white blood cells to digest the antigen, and by activating other body substances to help destroy the antigens.

The causes of most forms of vasculitis remain unknown. One kind of vasculitis that is not infrequently associated with peripheral neuropathy is polyarteritis nodosa. In addition, sarcoidosis can cause peripheral neuropathy from a vasculitis.

(Not all treatments and therapies may be indicated.)
