AIM To determine how the auto-antibodies (Abs) profiles overlap in chronic hepatitis C infection (CHC) and autoimmune hepatitis (AIH) and correlate to liver disease. METHODS Levels of antinuclear Ab, smooth muscle antibody (SMA) and liver/kidney microsomal-1 (LKM-1) Ab and markers of liver damage were determined in the sera of 50 patients with CHC infection, 20 AIH patients and 20 healthy con...

Pemphigus is an autoimmune disease in which IgG auto-antibodies (auto-ab) against the desmosomal cadherins desmoglein (Dsg) 3 and Dsg1 cause loss of epidermal keratinocyte adhesion. Aim of this study was to investigate cytokines derived from antigen-presenting cells (APC) and their relation to CD4+ T cell subpopulations and to the auto-ab response in pemphigus. In this regard, patients with pem...

Autoimmune haemolytic anaemia is characterised by the formation of auto-antibodies that bind to the erythrocyte surface membrane, leading to haemolysis. It is the main cause of acquired extracorpuscular haemolysis in children. It can be classified according to the characteristic temperature reactivity of the red blood cell auto-antibody in warm-antibody autoimmune haemolytic anaemia (reacting a...

alterations have been found to occur in every component of immune response during an anesthesia and surgery. these alterations represent the body's general physiological responses and are mainly depended on the extent of surery as well as on blood transfusion. basically, the immune response to an anesthesia and surgery is a beneficial reaction needed in local defences, wound healing, and p...

Castleman disease is a syndrome with significant clinico-pathological overlap between malignancy, autoimmune causes and infectious etiologies. It spectrum can vary in extent from unicentric to multicentric generalized lymphadenopathy, organ involvement, constitutional symptoms cytopenias, severity non-severe severe TAFRO symptoms. Idiopathic (iMCD) diagnosis of exclusion after multiple as per d...

Aetiology and pathogenesis of amyotrophic lateral sclerosis (ALS) is still a mystery. Among several hypotheses autoimmune mechanisms are also taken into account. We report here our investigations of auto-antibodies against proteins of spinal cord cells in the cerebrospinal fluid (CSF) and serum of ALS patients. The results were correlated with the severity of disease course. The subjects were 5...

Hodgkin lymphoma (HL) is a potentially curable lymphoma, and modern therapy is expected to successfully cure more than 80% of the patients. Second-line salvage high-dose chemotherapy and autologous stem cell transplantation (auto-SCT) have an established role in the management of refractory and relapsed HL, leading to long-lasting responses in approximately 50% of relapsed patients and a minori...

Chronic idiopathic thrombocytopenic purpura (chronic ITP) is an autoimmune disorder characterized by bleeding tendency and the presence of auto-antibody to platelets. Quantitative analysis of the level of anti-platelet antibodies and platelet associated antibodies is now possible. Furthermore, recent immunological techniques have enabled us to detect target platelet antigens in chronic ITP. In ...

Aims Non-enzymatic glycation of DNA both in vivo and in vitro results in generation of free radicals, known as glycoxidation. Glycoxidation leads to structural perturbation of DNA resulting in generation of neo-antigenic epitopes having implication in autoimmune disorders like diabetes mellitus. In this study human placental DNA was glycated with methylglyoxal (MG) and lysine (Lys) in the prese...

Over-activation of B7/CD28 co-stimulatory signal is believed to play an important role in promoting hyperfunctional immune response which contributes to autoimmune diseases. In the present study, we generated the recombinant lentivirus transcribing short hairpin RNA (shRNA) specific for mouse B7-2 gene silencing and B7/CD28 signal inhibition to explore and evaluate a potential candidate approac...
