Alzheimer's Disease and Effects of Polymorphisms: A Review.

Alzheimer's Disease (AD) is a progressive neurodegenerative disease and the main cause of dementia. Its etiology remains largely unclear, though genetic and environmental factors appear to confer susceptibility to AD development. This study assessed the role of ATP-binding Cassette A Subfamily 7 () genetic polymorphisms, as ongoing research suggests they have a role in the development of AD.

Neuropsychiatric symptoms and white matter hyperintensities in older adults without dementia.

Objective: We aimed to examine associations between neuropsychiatric symptoms (NPS) and white matter hyperintensities (WMH) status in older adults without dementia under the hypothesis that WMH increased the odds of having NPS.

Design: Longitudinal analysis of data acquired from the National Alzheimer's Coordinating Center Uniform Data Set.

Settings: Data were derived from 46 National Institute on Aging - funded Alzheimer's Disease Research Centers.

Quality of life in people with multiple sclerosis receiving glatiramer acetate or interferon in Greek clinical practice.

To evaluate glatiramer acetate (GA) or IFN-β effects on quality of life (QoL) in people with relapsing/remitting multiple sclerosis (PwRRMS) in Greece. A prospective, practice-based study. QoL/function/symptoms were assessed by seven questionnaires/scales.

Tetracyclines Diminish IFN-γ and IL-17-Producing Adaptive and Innate Immune Cells in Multiple Sclerosis.

Introduction: Limited data from clinical trials in multiple sclerosis (MS) reported that minocycline, a widely used antibiotic belonging to the family of tetracyclines (TCs), exerts a beneficial short-lived clinical effect A similar anti-inflammatory effect of minocycline attributed to a deviation from Th1 to Th2 immune response has been reported in experimental models of MS. Whether such an immunomodulatory mechanism is operated in the human disease remains largely unknown.

Aim: To assess the immunomodulatory effect of tetracyclines, and in particular minocycline and doxycycline, in naïve and treated patients with MS.

Progressive multifocal leukoencephalopathy in a patient with systemic sclerosis treated with methotrexate: A case report and literature review.

Reactivation of viruses occurs in autoimmune disorders in the setting of certain immunosuppressive drugs. We describe a 54-year-old female with systemic sclerosis and extensive cutaneous calcinosis who had been treated with methotrexate for 18 months and presented with headache and neurological deficits. She was diagnosed with progressive multifocal leukoencephalopathy, a rare disease caused by JC virus.

Recurrent episodes of syncope requiring pacemaker implantation as an initial presentation of neuromyelitis optica spectrum disorder.

Neuromyelitis Optica Spectrum Disorders (NMOSD) can manifest with a variety of heterogeneous symptoms, mainly encompassing optic neuritis, acute myelitis and area postrema syndrome (hiccups, nausea, and vomiting). Syncopal episodes have rarely been described as an initial manifestation of NMOSD. Here, we report a case of a 42-year-old male who was diagnosed with NMOSD after initially presenting with intractable hiccups and recurrent episodes of syncope.

A comprehensive analysis of antigen-specific autoimmune liver disease related autoantibodies in patients with multiple sclerosis.

Introduction: Abnormal liver function tests are frequently seen in patients with multiple sclerosis (MS) and their origin at times is attributed to the possible co-occurrence or the de novo induction of autoimmune liver diseases (AILD), namely autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC), but comprehensive analysis of AILD-related autoantibody has not been carried out.

Aim: To assess the presence of AILD-related autoantibodies in a well-defined cohort of MS patients, and to assess their clinical significance.

Materials And Methods: 133 MS (93 female) patients (102 RRMS, 27 SPMS, and 5 PPMS), mean age 42.

Brain volume dynamics in multiple sclerosis. A case-control study.

: In this study, we aimed to explore the extent and clinical relevance of brain volume dynamics in relapsing remitting multiple sclerosis (RRMS). : Sixty-three patients with RRMS with a disease duration of about 5 years (36 women, mean age 39.9 ± 9.

Autoimmune hepatitis in patients with multiple sclerosis: The role of immunomodulatory treatment.

Background: Development of autoimmune hepatitis (AIH) has been sporadically reported in patients with multiple sclerosis (MS) either concurrently or after treatment with immunomodulatory drugs, including interferon-beta (IFN-β) and steroids.

Aim: To report a large cohort of 14 patients with MS diagnosed with AIH during an assessment of deranged liver function tests (LFTs).

Patients And Methods: From 2005 to 2017, we prospectively identified 14 (13 women) patients with MS who suffered also from AIH after investigation in our department for the presence of deranged LFTs.

Regulatory B and T lymphocytes in multiple sclerosis: friends or foes?

Current clinical experience with immunomodulatory agents and monoclonal antibodies in principle has established the benefit of depleting lymphocytic populations in relapsing-remitting multiple sclerosis (RRMS). B and T cells may exert multiple pro-inflammatory actions, but also possess regulatory functions making their role in RRMS pathogenesis much more complex. There is no clear correlation of Tregs and Bregs with clinical features of the disease.

Replication study of GWAS risk loci in Greek multiple sclerosis patients.

Objectives: To validate in an ethnically homogeneous Greek multiple sclerosis (MS) cohort, genetic risk factors for the disease, identified through a number of previous multi-ethnic genome-wide association studies (GWAS).

Methods: A total of 1228 MS cases and 1014 controls were recruited in the study, from 3 MS centers in Greece. We genotyped 35 susceptibility SNPs that emerged from previous GWAS or meta-analyses of GWAS.

Immune responses against Helicobacter pylori-specific antigens differentiate relapsing remitting from secondary progressive multiple sclerosis.

To assess whether Helicobacter pylori (Hp) antibody (ab) reactivity against individual Hp antigens is pathogenetically relevant to multiple sclerosis (MS), we systematically investigated prevalence and clinical significance of abs against 14 immunodominant and subdominant Hp antigens by ELISA and immunoblotting in 139 consecutive MS patients with relapsing-remitting (RRMS, n = 102) or secondary progressive (SPMS, n = 37). Sera from 39 patients with Parkinson's disease (PD), 21 with Alzheimer's disease (ALZ) and 68 healthy controls (HCs), were also tested. Anti-flagellin (18.

Anti-hsp60 antibody responses based on Helicobacter pylori in patients with multiple sclerosis: (ir)Relevance to disease pathogenesis.

In view of published data suggesting that Helicobacter pylori (Hp) is a trigger of multiple sclerosis (MS), we assessed anti-heat shock protein 60 (hsp60)Hp antibody reactivity in 129 MS patients and 48 demograpically-matched healthy controls (HCs). Anti-Hp antibodies by ELISA were more elevated in MS than HCs but did not differ between different MS phenotypes. All anti-Hp-positive MS sera, irrespectively of their clinical phenotype, were anti-anti-hsp60 positive.

Interleukin-1B and interleukin-1 receptor antagonist gene polymorphisms in Greek multiple sclerosis (MS) patients with bout-onset MS.

We investigated the association of specific polymorphisms of the interleukin IL-1b (AvaI -511 and TaqI +3,953) and IL-1 receptor antagonist (IL-1RN) (a variable number of tandem repeats; VNTR) genes with both the susceptibility to and the clinical characteristics in Greek multiple sclerosis (MS) patients cohort with bout-onset. Genotypes were determined from 351 patients with clinically definite MS and 375 age- and sex-matched healthy controls. Our results showed no significant differences in the distribution of these polymorphisms between MS patients and controls.
