A prospective study of acute idiopathic neuropathy. I. Clinical features and their prognostic value.

TLDR

The study aims to develop a statistical model combining four variables to predict individual outcomes in acute idiopathic neuropathy. The researchers conducted a 15‑month prospective cohort study of 100 patients with acute idiopathic neuropathy in South‑East England. At 12 months, 67% of patients had fully recovered, 20% remained significantly disabled, and 13% died (ten due to neuropathy), with early bedbound time, ventilation need, age over 40, and small or absent abductor pollicis brevis potentials predicting persistent disability.

Abstract

A prospective study in South-East England during 15 months in 1983-1984 recruited 100 patients with acute idiopathic neuropathy. After 12 months 67% had recovered completely, 20% were still significantly disabled and 13% had died. Ten of the 13 deaths were attributable to the neuropathy. The major features in the initial assessment which were associated with persistent disability were the time taken to become bedbound, requirement for ventilation, age greater than 40 years, and small or absent compound abductor pollicis brevis muscle action potentials elicited by stimulation of the median nerve at the wrist. These four variables have been combined in a statistical model to predict outcome for individual patients with acute idiopathic neuropathy.
