Of 19 unselected patients with the diagnosis of amyotrophic lateral
sclerosis (ALS) living in Suffolk County, New York (an area of high Lyme
disease prevalence), 9 had serologic evidence of exposure to Borrelia
burgdorferi; 4 of 38 matched controls were seropositive. Eight of 9
seropositive patients were male (8 of 12 male patients vs 2 of 24
controls). Rates of seropositivity were lower among patients with ALS from
nonendemic areas. All patients had typical ALS; none had typical Lyme
disease. Cerebrospinal fluid was examined in 24 ALS patients--3 (all with
severe bulbar involvement) appeared to have intrathecal synthesis of anti-B
burgdorferi antibody. Following therapy with antibiotics, 3 patients with
predominantly lower motor neuron abnormalities appeared to improve, 3 with
severe bulbar dysfunction deteriorated rapidly, and all others appeared
unaffected. There appears to be a statistically significant association
between ALS and immunoreactivity to B burgdorferi, at least among men
living in hyperendemic areas.
