objective: the study aimed to determine the relationship between presence of antiphospholipid antibodies (apls) and clinical pregnancy rate in patients undergoing ivf/icsi procedures. materials and methods: this descriptive-analytic study performed on two hundred consecutive women referred for ivf/icsi in vali-e-asr reproductive health research center. serum levels of apls , anticardiolipin [ac...

PEARLS Limbic encephalitis is an inflammatory condition of the brain, often characterized by the subacute onset of short-term memory loss, disorientation, seizures, behavioral disturbance, and psychiatric symptoms. Besides paraneoplastic syndromes with onconeural antibodies targeted against intracellular neuronal antigens, limbic encephalitis may also arise from nonparaneoplastic mechanisms wit...

background & aim: multiple sclerosis(ms) is the most common inflammatory disease of central nervous system which is caused by an autoimmune process leading to destruction of myelin sheath. in this disease, cd4+ t–lymphocytes, mostly of th1 phenotype, play important roles in destruction of neuronal tissues.  because of the probable etiologic participation of ebv virus in immunopathogenesis of ms...

background : type 1 diabetes mellitus (t1dm) is an autoimmune disease characterized by selective destruction of pancreatic beta cells.   methods: the study included 80 children, 20 of them have t1dm, 40 children were selected from first degree relatives to the same child and 20 healthy children serve as control. body mass index (bmi) was calculated, random blood glucose and glycosylated hemoglo...

Objectives: Anti-ganglioside antibodies are present in about half of the patients with Guillain-Barré syndrome (GBS). Recently it has been shown that a considerable proportion of these patients has serum antibodies against antigenic epitopes formed by a complex of two different gangliosides. However, direct experimental evidence for neuropathogenicity of this special category of antibodies is c...

Objective Novel clinical and laboratory findings in anti-neurofilament heavy chain encephalitis Background Antibodies to mature components of neuronal intermediate filament (NIF) have been implicated several neurological disorders, including multiple sclerosis, amyotrophic lateral more recently, various autoimmune encephalitides. The include a-internexin, light chain. In the largest case series...

The diagnostic value of the presence of anti-neuronal antibodies in serum was examined in 21 patients suspected of paraneoplastic disorders of the nervous system (NS) (group 1) and was compared to three control groups; group 2: 25 patients with a neurological disease, without cancer and no sign of paraneoplastic disorder; group 3: 27 patients with neurological disease and cancer and no signs of...

Two categories of cell death related to antigens, apogens and engulfens, have been reported to be expressed by apoptotic cells and the cells involved in their engulfment in the immune system, and in mesenchymal tissue in the limb of the chick embryo (ROTTELLO et al., 1994). To determine whether these antigens are also expressed during the process of neuronal death, the distribution of immunorea...

The pathogenesis of neuropsychiatric syndromes of systemic lupus erythematosus (NPSLE) is multifactorial and can involve various inflammatory cytokines, autoantibodies such as anti-neuronal antibodies, anti-ribosomal P antibodies, anti-NR2 glutamate receptor binding antibodies, anti-Sm antibodies, anti-U1-RNP antibodies and anti-phospholipid antibodies, and immune complexes (IC). Disruption of ...

Anti-N-methyl D-aspartate receptor (anti-NMDAR) encephalitis is the most common and best described of autoimmune syndromes associated with neuronal cell surface or synaptic autoantibodies. It typically characterised by a progressive clinical course involving confusion, psychosis, seizures, dysautonomia altered consciousness has increasingly been diagnostic consideration for clinicians given gre...
