How does leprosy cause peripheral neuropathy?

Leprosy, a chronic infectious disease caused by Mycobacterium leprae, identified by G. H. A. Hansen in 1873, is one of the most common treatable peripheral neuropathy in the world. Leprosy causes a ‘mononeuritis multiplex’ of immunological origin that results in autonomic, sensory and motor neuropathy 1.

Which nerve affects leprosy?

The involvement of the median nerve at the wrist, the ulnar nerve at the elbow, and the common peroneal nerve at the fibular head are common in leprosy and may lead to difficulty in distinguishing this condition from idiopathic entrapment neuropathy involving these nerves.

How does leprosy damage the body?

It primarily affects the nerves of the extremities, the skin, the lining of the nose, and the upper respiratory tract. Leprosy is also known as Hansen’s disease. Leprosy produces skin ulcers, nerve damage, and muscle weakness. If it isn’t treated, it can cause severe disfigurement and significant disability.

What causes thickened nerves?

INFECTIVE CAUSES Leprosy is the most common infective cause of enlarged nerves. Other infections, such as tuberculosis, syphilis, Lyme disease, mycoplasma and schistosomia- sis, rarely cause thickened nerves. Enlarged nerves in patients with AIDS can have infective, immune or neo- plastic causes.

Which nerve is most commonly involved in leprosy?

Mononeuritis is the most common presentation of leprosy, and the nerves in the upper limbs are more often affected than those of the lower. The most commonly involved nerves are the ulnar, median, posterior auricular, superficial radial, common fibular, superficial fibular and posterior tibial 4.

How did you catch leprosy?
