Cases of Guillain-Barré syndrome, its variants, and chronic inflammatory demyelinating neuropathy presenting during the period 1980-84 were identified through computer-based record systems. Case notes were examined, and cases that did not meet standard criteria for diagnosis were excluded. A hundred and ten patients were identified, giving an annual adult incidence rate of 0.9/100,000 and a male:female ratio of 1.3:1. The majority of cases developed severe tetraparesis, but unusual presentations included the Miller-Fisher variant, paraplegia, and bibrachial involvement. There was wide variation in peak disability, ranging from ambulant with weakness (32%), through bedfast but without significant respiratory involvement (29%), to respiratory involvement requiring admission to an intensive care unit (38%). Of those discharged directly home, the average hospital stay for those less than 50 years was 27 days, whilst that for those over 50 was 49 days. CSF protein was measured in 87 patients, and was greater than or equal to 0.6 g/L in 76% of these. Nerve conduction studies were performed in 52 patients, and were abnormal in 90% of these. Guillain-Barré syndrome and allied conditions represent a major drain on health resources, and the need to provide adequate plasmapheresis facilities for patients early in the course of severe disease is stressed.
