Chronic inflammatory demyelinating polyneuropathy (CIDP) can be seen in patients with immunologic diseases. Treatment may aid recovery, but a chronic course may ensue. Bacterial infections produce signs of acute inflammation with redness and swelling and tend not to involve nerves specifically. Some paraneoplastic syndromes may occur with carcinomas, such as Lambert-Eaton myasthenic syndrome, with weakness. Carcinomas are less likely at this age and are not frequent complications of HIV infection. Hyperglycemia is characteristic of diabetes mellitus, and diabetic neuropathy is likely to be progressive and unremitting. Traumatic injury is unlikely to produce such widespread findings and unlikely to be followed by a variable course.
