Abstract
Neuromyopathies developed in 3 patients with gluten-sensitive enteropathy, a long time after they had been cured of their digestive disease by following a gluten-free diet. These cases differed radically from typical deficiency neuropathies by the presence of microvascular inflammatory lesions in nerves and muscles. The semiological findings were similar in all 3 cases, and were distinguished by the association of signs evoking lesions of the largest myelinated nerve fibers to the posterior rami with lesions in the muscles. Corticotherapy improved the condition but did not affect its chronic course. Nerve and muscle biopsies revealed the presence of segmentary microvasculitis, mainly lymphohistiocytic. The probable mechanism of these histological changes is alterations in the circulating immune-complexes, usually found in gluten-sensitive enteropathy, producing various types of associated disorders. Some of these immune-complexes would not be directly effected by digestive intolerance to gluten, but would persist during the gluten-free diet period, and could be responsible for the microangiitis.
