Abstract

Introduction: Sjögren syndrome is thought to be a lymphocyte-driven process. Peripheral nervous system involvement occurs in about 20%-25% of patients. A sensory-predominant, large-fiber peripheral neuropathy is most common, and it is usually associated with a subacute to chronic presentation. Methods: We report a rare case of an acute Sjögren-associated, sensory predominant, length-dependent peripheral neuropathy mimicking Guillain-Barré syndrome. The patient presented with sensory ataxia preceded by fever and polyarthralgia. She gave a history of years of dry eyes and dry mouth. Results: She had a positive Shirmer test, abnormal salivary gland scan, and positive SS-A and SS-B antibodies. A sural nerve biopsy showed an unusual, dense, non-IgG4, polyclonal, plasma-cell perivascular infiltrate. The patient responded to treatment with weekly pulse intravenous methylprednisolone. Conclusions: Sjögren syndrome can present with acute-onset, sensory predominant peripheral neuropathy. The role of plasma cells in Sjögren syndrome is unexplored and deserves further study.
