Cytomegalovirus infection and Guillain-Barré syndrome: the clinical, electrophysiologic, and prognostic features. Dutch Guillain-Barré Study Group.

Guillain-Barré syndrome (GBS) is usually preceded by infections, in particular cytomegalovirus (CMV) and Campylobacter jejuni infection. We studied the clinical and electrophysiologic features of 20 CMV-associated GBS patients and compared the findings with earlier established data of C. jejuni-related GBS patients (n = 43) and of GBS patients without these infections (n = 71). The patients all participated in the Dutch GBS trial in which we compared the effect of intravenous immune globulins and plasma exchange. We demonstrate that CMV-related GBS patients have a different clinical pattern in comparison with the other two GBS groups. They are significantly younger, initially have a severe course indicated by a high frequency of respiratory insufficiency, and often develop cranial nerve involvement and severe sensory loss. This is in contrast to C. jejuni infection, which is associated with motor GBS. Both infections are associated with delayed recovery compared with the GBS patients without these infections.
