[Guillain-Barré syndrome in a child with normal tendon reflexes]

We describe the case of a 10-year-old child with the acute motor axonal neuropathy (AMAN) form of Guillain-Barré syndrome (GBS) with preserved tendon reflexes, 6 days after a bout of gastroenteritis. The child quickly showed weakness of the distal muscles of his four limbs, with preserved tendon reflexes and a raised CSF protein concentration with no cells. Nerve conduction studies showing motor axonal degeneration confirmed the diagnosis of GBS in spite of preserved tendon reflexes. The serum was positive for IgG antibodies to gangliosides GM1 and GD1b. The child received intravenous immunoglobulins, which resulted in a favorable progression. This case proves that GBS with normal tendon reflexes exists. The other cases of SGB with preserved tendon reflexes already described in the literature were the AMANs form with antibodies to gangliosides in the serum and only adults were affected.
