Justin.Jordan@phhs.orgAbstractA 54-year-old white man presented with slowly progressive incoordination and weakness. He had normal motor development until, at 16 years of age, he noted difficulty walking and difficulty reading despite normal visual acuity. By the fourth decade of life, he developed poor coordination and balance, as well as inability to walk. In subsequent years, he developed progressive, painless sensory loss, weakness, and atrophy in his distal arms and legs. His vision problems progressed and he also developed dysarthria without dysphagia. Family history was negative except for an uncle who was described as "clumsy." Results of an oculomotor examination were notable for increased square-wave jerks, persistent bilateral gaze-evoked nystagmus with saccadic pursuit, intact vestibulo-ocular reflex, and saccadic dysmetria. He had a mixed dysarthria with flaccid and ataxic characteristics and severe weakness and atrophy in the distal limb muscles. Sensation was diminished to the midforearms and midthighs in all modalities. Deep tendon reflexes were absent throughout, with no response to plantar stimulation. He had marked appendicular ataxia with mild axial ataxia. Magnetic resonance imaging of the brain revealed severe cerebellar atrophy. Results of an electrodiagnostic study suggested a severe axonal sensorimotor polyneuropathy with active and chronic denervation. The differential diagnosis in a patient with ataxia, neuropathy, and oculomotor features is discussed; a methodical approach to the diagnostic workup is suggested; and the final diagnosis is revealed.

  • Guillain-Barré syndrome associated with normal or exaggerated tendon reflexes.
  • Yuki N, Kokubun N, Kuwabara S, Sekiguchi Y, Ito M, Odaka M, Hirata K, Notturno F, Uncini A.Author information Departments of Microbiology and Medicine, National University of Singapore, Block MD4A, Level 5, 5 Science Drive 2, Singapore 117597, Singapore. micyuki@nus.edu.sgAbstractAreflexia is part one of the clinical criteria required to make a diagnosis of Guillain-Barré syndrome (GBS). The diagnostic criteria were stringently developed to exclude non-GBS cases but there have been reports of patients with GBS following Campylobacter jejuni enteritis with normal and exaggerated deep tendon reflexes (DTRs). The aim of this study is to expand the existing diagnostic criteria to preserved DTRs. From the cohort of patients referred for anti-ganglioside antibody testing from hospitals throughout Japan, 48 GBS patients presented with preserved DTR at admission. Thirty-two patients had normal or exaggerated DTR throughout the course of illness whereas in 16 patients the DTR became absent or diminished during the course of the illness. IgG antibodies against GM1, GM1b, GD1a, or GalNAc-GD1a were frequently present in either group (84 vs. 94%), suggesting a close relationship between the two groups. We then investigated the clinical and laboratory findings of 213 GBS patients from three hospital cohorts. In 23 patients, eight presented with normal tendon reflexes throughout the clinical course of the illness. Twelve showed hyperreflexia, with at least one of the jerks experienced even at nadir, and exaggerated reflexes returning to normal at recovery. The other three had hyperreflexia throughout the disease course. Compared to 190 GBS patients with reduced or absent DTR, the 23 DTR-preserved patients more frequently presented with pure motor limb weakness (87 vs. 47%, p = 0.00026), could walk 5 m independently at the nadir (70 vs. 33%, p = 0.0012), more frequently had antibodies against GM1, GM1b, GD1a, or GalNAc-GD1a (74 vs. 47%, p = 0.014) and were more commonly diagnosed with acute motor axonal neuropathy (65 vs. 34%, p = 0.0075) than with acute inflammatory demyelinating polyneuropathy (13 vs. 43%, p = 0.0011). This study demonstrated that DTRs could be normal or hyperexcitable during the entire clinical course in approximately 10% of GBS patients. This possibility should be added in the diagnostic criteria for GBS to avoid delays in diagnosis and effective treatment to these patients.
