Autoimmune autonomic ganglionopathy is a disorder of isolated autonomic failure associated with antibodies to the nicotinic acetylcholine receptor of the autonomic ganglia resulting in severe orthostatic intolerance, syncope, constipation, gastroparesis, urinary retention, dry mouth, dry eyes, blurred vision and anhidrosis. We report the autonomic test results, antibody titers and clinical findings in 8 patients with antibodies to the nicotinic acetylcholine receptor of the autonomic ganglia. There was a sigmoidal relation between the antibody titers and the fall in systolic blood pressure (r(2)=0.84). The threshold occurred with antibody titers of approximately 1 nmol/l. Over the linear portion of the sigmoid curve, with antibody titers in the 1-3 nmol/l range, increasing antibody titers resulted in more severe orthostatic hypotension (r=0.94, P<0.001). The saturation point of the sigmoidal relation occurred at approximately 3 nmol/l with drops in systolic blood pressure of approximately 100 mmHg during upright tilt. The antibody titers correlated inversely with the Valsalva ratio (r=-0.87, P<0.001), the 30:15 ratio (r=-0.84, P<0.001) and the expiratory to inspiratory ratio (r=-0.67, P<0.01). Patients with orthostatic intolerance, anhidrosis, constipation, urinary dysfunction, sicca syndrome and pupillary dysfunction had higher antibody titers than subjects that did not (P<0.01 in all cases). Autoimmune autonomic ganglionopathy is a clinically heterogeneous disease with variable presentation, particularly in subjects with lower antibody titers. Our data suggest that patients with higher antibody titers have wide spread dysautonomia while those with lower antibody levels may present with, or evolve into, more focal or restricted presentations.

The study aimed to present a case of ocular syphilis mimicking Vogt-Koyanagi-Harada (VKH) disease. This is an observational case report. A 59-year-old female with Sicca syndrome and rheumatoid arthritis presented to the ophthalmologic department with blurred vision of the right eye for 5 days accompanied by color sensation loss in both eyes. Bilateral disc hyperemia and serous retinal detachment at the posterior pole were noted in her both eyes by fundus examination. Fluorescein angiography revealed bilateral late dye leakage from the disc and posterior choroid. Optical coherence tomography showed bilateral subretinal fluid and choroidal thickening. The impression of her condition was VKH disease initially. However, she was later diagnosed with bilateral ocular syphilis with optic neuritis which was proved by laboratory data. After appropriate antimicrobial agent treatment, her best-corrected visual acuity, serous retinal detachment, and disc hyperemia improved. There was no recurrent intraocular inflammation even without systemic steroid or immunosuppressive therapy control during the following 1 year. Ocular syphilis can mimic many other ocular inflammatory diseases including VKH disease. It is necessary to differentiate infectious causes from inflammatory origins due to the substantially different treatment and prognosis.
