Discussion of Clinical Trials Relating to Peripheral Neuropathies

Two major types of peripheral neuropathy have been the subject of clinical trials. These are diabetic polyneuropathy and acquired demyelinating polyneuropathies, acute and chronic. The acute form is Guillain-Barré syndrome (GBS), and the chronic form is known as chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Hughes has, quite rightly, emphasized only the controlled studies of these polyneuropathies.
