Intravenous immunoglobulin treatment for painful sensory neuropathy associated with Sjögren's syndrome.
Journal of the Neurological Sciences 2009 April 16
BACKGROUND: Patients with painful sensory neuropathy associated with Sjögren's syndrome-associated neuropathy often show severe neuropathic pain which is not relieved by conventional treatments.
OBJECTIVE: To evaluate the effect of intravenous immunoglobulin (IVIg) therapy in the treatment of neuropathic pain associated with Sjögren's syndrome.
PATIENTS AND METHODS: We examined 5 patients affected by painful sensory neuropathy associated with Sjögren's syndrome. All patients were treated with IVIg (0.4 g/kg/day for 5 days) and pain rating was assessed by the Visual Analogue Scale (VAS).
RESULTS: All five patients showed a remarkable improvement in neuropathic pain following IVIg therapy. Pain, assessed by the determination of mean VAS score, was reduced by 73.4% from days 2-14 following treatment. The observed clinical improvement persisted for 2 to 6 months. One patient, examined by quantitative sensory testing (QST), showed an improvement of superficial sensory deficit accompanied by pain relief.
CONCLUSION: IVIg might be an effective treatment for pain in Sjögren's syndrome-associated neuropathy. Further studies should be done in a controlled, blind study.
