Despite many advances in the treatment of breast cancer, it is still the second most common cause of death in women in the United States. It has been shown that inflammation plays a major role in the treatment of these cancers and inflammatory factors enhance tumor growth, invasion, metastasis, and vascularization. In this study, we would like to analyze peripheral blood neutrophil-lymphocyte ratio (NLR) in breast cancer patients and its correlation with disease staging. This cross-sectional analytic study was conducted in Imam Hospital, affiliated with Tehran University of Medical Sciences; a total of 195 female patients with breast cancer met the inclusion criteria...

BACKGROUND & AIMS: Vitiligo is a pigmentary disorder and autoimmune pathogenesis seems most likely. Decreased vitamin D levels have been related to several autoimmune diseases. Little is known about the association of vitiligo and vitamin D. We aimed to evaluate serum 25-hydroxyvitamin D [25(OH)D] levels in children with vitiligo and to determine the efficacy of oral vitamin D therapy on the repigmentation of vitamin D deficient patients. METHODS: Thirty patients aged 6-17 years with vitiligo and 30 sex- and age-matched apparently healthy controls were included in this prospective study...

Autoimmune neurological diseases are an important group of pathologies in neuropaediatrics. The central nervous system was considered to be an immunologically privileged organ, as it protects itself from the surroundings by means of the blood-brain barrier. In recent years, however, reports have been published of a growing number of disorders produced by antibodies that react against neuronal or glial proteins and give rise to a wide variety of clinical conditions (epilepsy, encephalopathy, movement disorders, etc...

RATIONALE: Latent autoimmune diabetes in adults (LADA) refers to an autoimmune disorder characterized with detectable islets antibodies in the early diagnosis and increased autoimmune beta-cell failure progression. Notably, this kind of diabetes seems to be confused with other phenotypic diabetes. PATIENT CONCERNS: A young woman suffered an emotional exhaustion-induced LADA, showing asthenia, polydipsia, polyuria, and visible weight loss. The patient emotionally ended a 14-year romantic relationship, leading to the emotional flooding...

Acute pancreatitis (AP) with infectious complications has high mortality because of early-stage immunosuppression. The programmed cell death-1 (PD-1)/programmed cell death ligand 1 (PD-L1) pathway is an important host immunosuppression mechanism. Soluble PD-L1 (sPD-L1) expression regulates coinhibitory signals in malignancies or autoimmune disorders; however, its effects in AP are unknown. Here, we evaluated whether serum sPD-L1 is involved in immune dysfunction and assessed its relationship with infectious complications in early AP...

Glucocorticoids are among the most frequently used anti-inflammatory and immunosuppressive drugs. They are widely used in the treatment of numerous autoimmune disorders. However, the treatment with glucocorticoids is connected with the risk of a number of side effects. Among them, glucose tolerance disorders play an important role. The results of meta-analyses show that the risk of diabetes is from 1.4 to 2.5 times higher in the case of treated patients in comparison to the general population. Glucocorticoids can directly impair pancreatic β-cell secretion...

INTRODUCTION: The ultimate aim of pretransfusion testing is the acceptable survival of donor red cells in recipient's body and antibody detection plays a critical role in achieving the same. The cornerstone of antibody detection method is detecting an unexpected antibody as against the expected antibodies of ABO blood group system. Autoantibodies can also interfere with the detection of clinically significant alloantibodies. AIM: To study the frequency of alloantibodies and autoantibodies in the healthy blood donors and patient population visiting our hospital...

Autoantibodies (AAbs) against glycolytic enzymes: aldolase, α-enolase, glyceraldehyde-3-phosphate dehydrogenase, and pyruvate kinase are prevalent in sera of patients with blinding retinal diseases, such as paraneoplastic [cancer-associated retinopathy (CAR)] and non-paraneoplastic autoimmune retinopathies, as well as in many other autoimmune diseases. CAR is a degenerative disease of the retina characterized by sudden vision loss in patients with cancer and serum anti-retinal AAbs. In this review, we discuss the widespread serum presence of anti-glycolytic enzyme AAbs and their significance in autoimmune diseases...

Phosphorylation and activation of p38 MAPK and NFκB pathways, along with the resulting overproduction of interleukin IL-1β, IL-6, and tumor necrosis factor a (TNFα) is a hallmark of inflammatory disorders. Omega-3 polyunsaturated fatty acid (n-3 PUFA) supplementations are known to exert anti-inflammatory properties by reduction of keys cytokines and enzymes involved in inflammation. Here, we investigated the anti-inflammatory pathways and mediators modulated by eicosapentaenoic acid monoglyceride (MAG-EPA) on human peripheral blood mononuclear cells (PBMCs) from healthy donors and stimulated, ex vivo, with lipopolysaccharide (LPS)...

Vitiligo is an acquired skin disease with pigmentary disorder. Autoimmune destruction of melanocytes is thought to be major factor in the etiology of vitiligo. miRNA-based regulators of gene expression have been reported to play crucial roles in autoimmune disease. Therefore, we attempt to profile the miRNA expressions and predict their potential targets, assessing the biological functions of differentially expressed miRNA. Total RNA was extracted from peripheral blood of vitiligo (experimental group, n = 5) and non-vitiligo (control group, n = 5) age-matched patients...

Rheumatoid arthritis (RA) is one of the most common autoimmune diseases, with a 0.5% world-wide prevalence. The cause of RA remains unknown, however both genetic and environmental factors may contribute to its development. Among these is the Epstein-Barr Virus (EBV). Here, we discuss several aspects of the close relationship between EBV and RA. Patients with RA have impaired control of EBV infection. Indeed, they have high titres of antibodies against EBV antigens. Their peripheral blood T lymphocytes are less efficient at controlling the outgrowth of EBV-infected B cells...

Antibodies against neuronal receptors and synaptic proteins are associated with autoimmune encephalitides (AE) that produce movement and psychiatric disorders. In order to exert their pathological effects on neural circuits, autoantibodies against central nervous system (CNS) targets must gain access to the brain and spinal cord by crossing the blood-brain barrier (BBB), a tightly regulated gateway formed by endothelial cells lining CNS blood vessels. To date, the pathogenic mechanisms that underlie autoantibody-triggered encephalitic syndromes are poorly understood, and how autoantibodies breach the barrier remains obscure for almost all AE syndromes...

BACKGROUND: Schizophreniform syndromes can be divided into primary forms from polygenic causes or secondary forms due to immunological, epileptiform, monogenic, or degenerative causes. Steroid-responsive encephalopathy associated with autoimmune thyroiditis (SREAT) is a secondary immunological form associated with increased thyroid antibodies, such as antithyroid peroxidase antibodies and shows a good response to corticosteroids.

Recent research on re-circulation of interstitial fluid from the brain parenchyma to the periphery and its inferred importance in immune surveillance dysregulation are changing our conceptualization of the pathophysiology of virus-induced autoimmunity. In this context, it is necessary to reassess the immunomodulatory properties of human defensins that are variably expressed by cerebral microglia, astrocytes and choroid plexus epithelial cells and exhibit complex and often confounding roles in neuroinflammatory processes...

Introduction. Acquired thrombotic thrombocytopenic purpura (TTP) has been associated with different autoimmune disorders. However, its association with pernicious anemia is rarely reported. Case Report. A 46-year-old male presented with blood in sputum and urine for one day. The vitals were stable. The physical examination was significant for icterus. Lab tests' results revealed leukocytosis, macrocytic anemia, severe thrombocytopenia, renal dysfunction, and unconjugated hyperbilirubinemia. He had an elevated LDH, low haptoglobin levels with many schistocytes, nucleated RBCs, and reticulocytes on peripheral smear...

BACKGROUND: HERVs expression seems impaired in several diseases, ranging from autoimmune to neoplastic disorders. However, various stimuli may re-activate HERVs transcription. Henoch-Schönlein purpura is the most common cause of vasculitis in children. The role of microbial antigens in the pathogenesis of HSP remains elusive. TLRs are the first line of defense for the host to initiate an immune and inflammatory response. We aimed to investigate HERV, K and W expression in peripheral mononuclear cells of children with HSP and relation with TLRs activation...

Neutrophil extracellular traps (NETs) are extracellular DNA filaments formed during neutrophil activation. This process, called netosis, was originally associated with neutrophil antibacterial properties. However, several lines of evidence now suggest a major role for netosis in thrombosis, autoimmune diseases, and cancer. We demonstrate here that highly purified human blood monocytes are also capable of extracellular trap (ET) release in response to several stimuli. Monocyte ETs display a morphology analogous to NETs and are associated with myeloperoxidase (MPO), lactoferrin (LF), citrullinated histones, and elastase...
