Peptide T in the treatment of painful distal neuropathy associated with AIDS: results of a placebo-controlled trial. The Peptide T Neuropathy Study Group.

OBJECTIVE: To assess the safety and efficacy of Peptide T in the treatment of painful distal symmetrical polyneuropathy (DSP) associated with human immunodeficiency virus (HIV) infection. BACKGROUND: Painful DSP is a frequent complication of HIV infection, although its etiology and optimal treatment are unknown. Peptide T (D-(alpha 1)-Peptide T-amide) has been found in phase I trials and anecdotal reports to relieve neuropathic pain in AIDS patients. DESIGN/METHODS: In this multicentered, double-blind, randomized study, subjects received intranasal Peptide T 6 mg/day or placebo for 12 weeks. The primary outcome measure was change in the modified Gracely pain score. Secondary efficacy variables were results of neurologic examination, neuropsychological and electrophysiologic studies, global evaluation, and CD4 lymphocyte counts. RESULTS: Of 81 evaluable subjects, 40 received Peptide T and 41 received placebo. The change in pain scores was not significantly different (p = 0.32) in the Peptide T group (-0.24) as compared to placebo (-0.39). Group comparisons were not significantly different for change in any clinical examination or neuropsychologic measure, sural nerve amplitude or conduction velocity, or CD4 lymphocyte count. No significant drug-related adverse effects occurred in either group. CONCLUSION: Intranasal Peptide T is safe but ineffective in the treatment of painful DSP associated with AIDS.

[The nutritional-viral etiology of epidemic neuropathy. The Group for the Study of Epidemic Neuropathy].

Viral sequences of the cerebrospinal fluid were amplified by using oligonucleotides that are homologous to region 5' of the Enteroviruses. The results showed a great variability in the amplified sequences, suggesting the presence of enteroviral quasispecies with altered biological properties in the stressed individuals that may play an important role in the neurological damage.

[A case of lead neuropathy--importance of subclinical entrapment of nerves in lead neuropathy].

The patient was a left handed 25-year-old man who had worked in a vinyl chloride resin factory since July 1987 using lead stearate as a stabilizer. During the two years preceding hospitalization, he had been admitted three times for colicky abdominal pain with constipation and nausea. Anemia and proteinuria without causative diseases were pointed out. Because of progressive muscle weakness of hands which began since January 1989, he was admitted to our neurologic clinic on October 2 1989. Neurological examination showed severe atrophy of both small hand muscles without sensory disturbances. Left hand was predominantly affected, especially in interossei muscles. Laboratory findings are as follows; RBC 3.25 million/cu.mm: Hb 9.7 g/dl:blood lead concentration 100 micrograms/dl: urinary coproporphyrin 4503 micrograms/l: urinary delta-ALA 138 mg/l: and urinary lead excretion after 1 g CaEDTA infusion: 3938 micrograms/day. Electromyography of extensor carpi radialis, flexor carpi ulnaris and opponens showed increased polyphasic, long duration MUPs. Electromyography of dorsal interossei showed fibrillation. Nerve conduction study showed mildly decreased motor and sensory conduction velocities and markedly reduced amplitude of compound muscle action potentials (CAMPs). Investigation by inching method revealed conduction block of left ulnar nerve across elbow. After CaEDTA chelating therapy, 1 g once a week, steady improvement of muscular weakness was observed within a few months. Serial nerve condition studies revealed constant recovery of nerve conduction velocities, amplitude of CMAPs and diminution of conduction block across the left elbow. Conduction block across left elbow without sensory disturbances implies that subclinical cubital tunnel syndrome might have existed in this patients.(ABSTRACT TRUNCATED AT 250 WORDS)
