To evaluate nervous system involvement in a cohort of Italian patients with primary Sjögren's syndrome (pSS), 87 unselected patients (83 female, and four male) observed consecutively at our institution over a period of 5 years were screened by clinical and instrumental (MRI, SPECT, electrophysiological testing, CSF analysis) investigations for peripheral and central neurological abnormalities. Seroimmunological parameters and extraglandular features other than neurological manifestations were also evaluated. Seven patients had central nervous system (CNS) disease (8%), mostly non-focal dysfunction, and 12 had peripheral nervous system (PNS) disease (13.8%), mostly mild or severe sensory or sensory-motor polyneuropathies. One patient had concomitant CNS and PNS involvement. Compared with CNS disease, PNS involvement occurred in older patients (> 50 years), independent of the disease duration. Patients with and without neurological abnormalities did not differ for seroimmunological parameters (including antiphospholipid antibodies) or extraglandular manifestations. From a statistical point of view, the only relevant finding was the detection of a slight increase in serum IgA and IgM levels (p < 0.05) in patients with an intact nervous system. Neurological involvement in pSS, be it central or peripheral, is not a rare finding. A careful clinical neurological evaluation, combined with a multiplicity of instrumental investigations, is recommended in the global assessment of pSS patients.

Abstract

To evaluate nervous system involvement in a cohort of Italian patients with primary Sjögren's syndrome (pSS), 87 unselected patients (83 female, and four male) observed consecutively at our institution over a period of 5 years were screened by clinical and instrumental (MRI, SPECT, electrophysiological testing, CSF analysis) investigations for peripheral and central neurological abnormalities. Seroimmunological parameters and extraglandular features other than neurological manifestations were also evaluated. Seven patients had central nervous system (CNS) disease (8%), mostly non-focal dysfunction, and 12 had peripheral nervous system (PNS) disease (13.8%), mostly mild or severe sensory or sensory-motor polyneuropathies. One patient had concomitant CNS and PNS involvement. Compared with CNS disease, PNS involvement occurred in older patients (> 50 years), independent of the disease duration. Patients with and without neurological abnormalities did not differ for seroimmunological parameters (including antiphospholipid antibodies) or extraglandular manifestations. From a statistical point of view, the only relevant finding was the detection of a slight increase in serum IgA and IgM levels (p < 0.05) in patients with an intact nervous system. Neurological involvement in pSS, be it central or peripheral, is not a rare finding. A careful clinical neurological evaluation, combined with a multiplicity of instrumental investigations, is recommended in the global assessment of pSS patients.
