  • Title: Plasma exchange treatment and prognosis of Guillain-Barré syndrome.
    Author: Smith GD, Hughes RA.
    Journal: Q J Med; 1992 Oct; 85(306):751-60. PubMed ID: 1287706.
    Abstract:
    A retrospective analysis of case notes was undertaken for 52 patients presenting to Guy's Hospital with Guillain-Barré syndrome between August 1987 and September 1990. Twelve months after onset 61 per cent of patients had recovered completely, 35 per cent were still significantly disabled and two patients (4 per cent) had died. Forty-eight of the patients (92 per cent) were treated with plasma exchange. The frequency of morbidity related to this treatment was low, and plasma exchange was not responsible for either of the deaths. Outcome for all patients treated with plasma exchange between January 1985 and September 1990 was compared with that of 64 patients with Guillain-Barré syndrome seen in 1983 and 1984 who were not treated in this way. Time to walking unaided was significantly better (median 58 days compared with 86 days, p = 0.031), as was the median duration of ventilation (16.5 compared with 36 days, p = 0.004). Factors which had been found to predict an adverse outcome in previous studies (requirement for ventilation, age over 40 years, time to becoming bedbound less than 4 days, and small distally evoked abductor pollicis brevis muscle action potential) were not significantly associated with a poor prognosis in this study. The features associated with persisting disability were time to improvement more than 21 days, preceding diarrhoea and older age.
