The impact of Behçet's disease on higher cognitive functions is still poorly understood. We proposed (1) to characterize the neuropsychological profile of Behçet's disease patients with (Neuro-BD) and without (BD) neurological manifestations; (2) to identify which clinical, psychopathological, and genetic variables are related to neuropsychological(More)
Systemic lupus erythematosus (SLE) is a prototypical autoimmune disease with strong genetic and environmental components. Previous studies have shown increased levels of several chemokines in active SLE. C-C chemokine receptor type 5 (CCR5) is involved in the recruitment of inflammatory cells into tissues, and mechanisms modulating CCR5 expression and(More)
BACKGROUND The association between susceptibility to multiple sclerosis (MS) and HLA-DRB1*15 has been reported in various European populations. OBJECTIVE To investigate the relationship between MS, HLA-DRB1*15 and other DRB1 alleles in a Portuguese population and their association with clinical course of MS. METHODS The HLA-DRB1 alleles were analyzed by(More)
From January 1980 to December 1991 we operated on 295 patients with a gastric carcinoma. In 166 cases (56.3%) surgery was performed with curative intent. In 93 patients (56%) a subtotal gastrectomy was performed, and in 73 cases (44%) a total gastrectomy. In all the cases a D-2 type lymphadenectomy was used. The global morbidity rate was 23%, and(More)
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease of unknown origin, in which both genetic and environmental factors are involved. One such environmental factor is vitamin D, a vital hormone that plays a specific function in the immune system homeostasis, acting through a nuclear receptor (VDR) expressed in all immune cells. Several(More)
BACKGROUND Not every individual exposed to Mycobacterium tuberculosis becomes infected. One host genetic factor, involved in modulating the immune response that has been studied in many ethnic groups is the association of human leukocyte antigens (HLA) with susceptibility to tuberculosis (TB). OBJECTIVE To investigate the association between TB, HLA-DRB1(More)
INTRODUCTION Behçet's disease (BD) is a multisystem inflammatory disease of unknown etiology that may affect the CNS - Neuro-Behçet (NB). Our aim was to evaluate the frequency of neurological involvement and characterize a cohort of our NB patients. METHODS We retrospectively revised the clinical, laboratory and imaging data of a cohort of BD patients,(More)
Systemic lupus erythematosus (SLE) is a clinically heterogeneous disease translating the different genetic and environmental factors involved. Polymorphisms at several loci, including the major histocompatibility complex (MHC), have been associated worldwide with SLE, although inconsistencies exist among these studies mainly due to genetic heterogeneity(More)
BACKGROUND Recent data suggest that cognitive reserve modulates the adverse effects of multiple sclerosis (MS) pathology on cognitive functioning; however, the protective effects of education in MS are still unclear. OBJECTIVE To explore education as an indicator of cognitive reserve, while controlling for demographic, clinical and genetic features. (More)
Human leukocyte antigen (HLA)-B*51 is a well-known genetic factor associated with Behçet's disease (BD). To analyse the influence of HLA-B*51 and other HLA class I alleles in BD susceptibility in a Portuguese population and its association with disease severity, we studied 78 BD patients and 208 healthy controls. The patients were classified into two(More)
