Sjogren syndrome associated with obsessive-compulsive disorder

OBJECTIVE: To describe a patient with Sjogren syndrome (SS) associated with obsessive-compulsive disorder (OCD). PATIENTS AND METHODS: Case report and systematic review of the literature. CASE REPORT: A 40-year-old female patient with a history of xerostomia and xerophthalmia initiated in 2015. She also had a history of changing her behavior, and she practices rituals, recurrent obsessions, and compulsions. She was diagnosed with OCD. She was treated with fluoxetine associated with risperidone and then was changed for aripiprazole 10 mg/day. Cognitive-behavioral therapy was also applied. She had good control of the obsessions with these drugs and psychotherapy. Laboratory tests showed positive antinuclear antibodies, anti-Ro/SS-A, and-La/SS-B antibodies. Schirmer test, break up time, and positive green lisamin were all positive. Scintigraphy and ultrasound of salivary glands were positive. A diagnosis of Sjogren syndrome was determined. She was treated with HCQ, vitamin D3 50,000 IU/week. omega-3 2 g. and artificial tears with a good response. Currently. 5 years later, the patient is asymptomatic and has OCD under adequate control even without drugs. CONCLUSIONS: This case illustrates a rare case of a patient with SS who evolved with OCD.
