To summarise, the peripheral neurological complications experienced by patients with primary Sjögren's syndrome are particularly bothersome since they are common and often result in significant disability related to pain or motor impairment. There is currently no standard treatment for these patients. As these neuropathies are caused by an immune system dysfunction, which is related to a variety of different pathogenic mechanisms, the use of immunosuppressant or immunomodulator drugs is often justified. With the exception of the vascularitis-related multiplex mononeuropathies, other pSS-related neuropathies could be suitable candidates for IV Ig treatment.
