Olfactory and Taste Disturbances in Sjogren's Syndrome

Olfactory and Taste Disturbances in Sjogren's Syndrome

Sjögren syndrome is an autoimmune disease, responsible for xerostomia and xerophthalmia. Other organs and tissues can be affected: the skin, vaginal and nasal mucous membranes. As well, olfactory disorders have been also described in Sjögren syndrome.

Xerostomia often causes significant functional impairment of taste function. Impairment of taste function has been poorly evaluated in Sjögren syndrome like olfactory or (intra-nasal and oral) trigeminal disorders.

The aim of the study is to evaluate olfactory, taste (intra-nasal and oral) trigeminal functions in patients with Sjogren's syndrome compared to patients without sicca syndrome.

Inclusion Criteria:

• group 1 : patients with Sjogren's syndrome
• group 2: patients without sicca syndrome
• older than 18 years old
• consenting to participate to the study

Exclusion Criteria:

• smoking patients
• patients with stomatitis
• patients with upper respiratory tract infection
