CALR and Sensory neuropathy: In Sène et al. study [25], patients with pSS and PNS involvement and nonataxic sensory neuropathy were characterized by a higher age (57.5 ± 10.7 versus 48.7 ± 14.3 years; P = 0.007), more frequent CNS involvement (15% versus 2%; P = 0.04), and lower prevalence of ANA (60% versus 90%; P = 0.003), anti-SSA (Ro) (40% versus 72%; P = 0.009), anti-SSB (La) (15% versus 41%; P = 0.039), RF (37% versus 67%; P = 0.02), and hypergammaglobulinemia (35% versus 64%; P = 0.023).
