"Dry oral and ocular manifestations and autoantibodies characteristic of primary Sjögren's syndrome in multiple sclerosis".

INTRODUCTION: The relationship between primary Sjögren syndrome (pSS) and demyelinating diseases is still not well understood. These diseases seem to coexist amidst autoimmunity, raising questions about clinical characteristics, relationship with immunomodulatory treatment, and possible common immunological background underlying their pathogenesis. OBJECTIVE: calculate the frequency of dry oral and ocular manifestations and autoantibodies characteristic of primary Sjögren's Syndrome in Multiple Sclerosis. METHODS: 202 patients with multiple sclerosis answered a questionnaire to identify complaints of xerostomia and xerophthalmia, according to diagnostic criteria for primary Sjögren's syndrome; 43 answered positively to at least one question; 27 had comorbidities or used drugs that cause dry symptoms and were excluded; 16 patients were selected for examinations for oral, ocular and serum anti-Ro/SS-A autoantibody evaluation. RESULTS: Eleven (68.75%) patients complained of xerostomia; 14 (87.5%) of xerophthalmia. Sialometry < 0.1 ml/min was observed in three (18.8%); 13 patients underwent minor salivary gland biopsy and histopathological examination: focal score > 1 in three (23.1%). Schirmer test was < 5 mm/5 min in four (25%). Lyssamine green/fluorescein dye score was > 5 in three (18.8%). Anti-Ro/SS-A > 10 UI/mm in two (12.5%). Three (1,49%) patients met current criteria for primary Sjögren's syndrome. CONCLUSIONS: Patients with MS may report xerostomia and/or xerophthalmia even in the absence of comorbidities and use of medications capable of causing these symptoms, which may fulfill the diagnostic criteria for pSS. In this study, the frequency of pSS according to current criteria was within the range observed in the literature with older criteria. But the question remains whether the association between these diseases is fortuitous or whether there is a pathogenic link.

A short neuropsychological evaluation of patients with primary Sjögren's syndrome.

OBJECTIVE: To investigate cognitive deficits in patients with primary Sjögren's syndrome (PSS). METHOD: Eighteen patients with PSS, aged between 25 and 61 years, were subjected to a short neuropsychological battery and compared with 18 patients with multiple sclerosis and 18 healthy controls. RESULTS: The analysis of variance (ANOVA) revealed that the clinical groups had significantly worse performance than the control group on the Rey Auditory Verbal Learning Test 3; (F(2,53) =3.500, p=0.038) and 7 (F(2,53) =5.068, p=0.010). The clinical groups had elevated levels of depression on the Beck Depression Inventory (BDI); (p=0.003). The analysis of the data from the Trail Making Test B-A revealed a significant difference between the clinical and control groups (p=0.023). The analysis of covariance with BDI score as a covariate, did not change the outcome. CONCLUSION: Our study revealed cognitive deficits in patients with PSS detectable by a short neuropsychological battery.

A short neuropsychological evaluation of patients with primary Sjogren's syndrome / Avaliacao neuropsicologica breve em pacientes com sindrome de Sjogren primaria

Objective: To investigate cognitive deficits in patients with primary Sjögren’s syndrome (PSS). Method: Eighteen patients with PSS, aged between 25 and 61 years, were subjected to a short neuropsychological battery and compared with 18 patients with multiple sclerosis and 18 healthy controls. Results: The analysis of variance (ANOVA) revealed that the clinical groups had significantly worse performance than the control group on the Rey Auditory Verbal Learning Test 3; (F 2,53 =3.500, p=0.038) and 7 (F 2,53 =5.068, p=0.010).

Objetivo: Investigar déficits cognitivos em pacientes com síndrome de Sjögren primária (SSP) utilizando bateria neuropsicológica breve. Método: Dezoito pacientes com SSP e idade entre 25 e 61 anos, foram submetidos a uma bateria neuropsicológica breve e os resultados comparados com 18 pacientes com esclerose múltipla e com 18 controles saudáveis. Resultados: A análise da variância revelou que os grupos clínicos apresentaram desempenho significativamente pior que os controles ao Rey Auditory Verbal Learning Test 3 (RAVLT 3; F 2,53 =3,500, p=0,038) e RAVLT 7 (F 2,53 =5,068, p=0,010). Os grupos clínicos apresentaram índices elevados de depressão pela Beck Depression Inventor y (BDI); (F 2,53 =0.003). O desempenho no Trail Making Test B-A revelou diferença significativa entre os grupos clínicos e o grupo controle (p=0,023). A análise de covariância tomando a BDI como covariante, não revelou mudanças nos resultados. Conclusão: Nosso estudo revelou comprometimento cognitivo em pacientes com SSP detectável por bateria neuropsicológica breve. .
