Background: Thalassemia is one of the most common genetic disorder hemoglobin synthesis in Jammu region. Although RBC transfusion life saving for these patients, it may be associated with some complications like alloimmunization. Thus, alloimmunization against red blood cell antigens increases need and can significantly complicate therapy. Therefore, screening unexpected antibodies should a par...

In this study, we aimed to determine the frequency of red cell allo- and autoimmunization and analyze the factors responsible for the development of antibodies in patients with transfusion-dependent thalassemia. This crosssectional study was conducted on 139 patients with thalassemia major and intermedia who received leukodepleted RBC transfusions on a regular basis. Patients with a positive an...

Thyroid hormone antibodies (THAbs)--i.e., antibodies to thyroxin (T4) and triiodothyronine (T3)--are detected rarely in human serum, where they are searched for, possibly because of a quantitatively minimal interaction between thyroid hormones (the haptens) and serum IgGs (the antibodies). The weak binding could result from these facts: (a) there are already six physiological carrier proteins f...

OBJECTIVE To investigate the effects of the multi-glycosides of Tripterygium wilfordii (GTW) on Sjögren's syndrome (SS) in the non-obese diabetic (NOD) mouse model. METHODS Twenty-seven 8-week-old, female NOD mice were divided into the GTW group, the hydroxychloroquine (HCQ) group, and control (normal saline) group, and received corresponding treatment for 16 weeks. The treatment-induced chan...

Background: Recurrent blood transfusion is a common treatment in patients with thalassemia. The development of antibodies against red blood cell (RBC) antigens complicates RBC cross-matching, enhances the in vivo destruction of transfused cells, accelerates tissue iron overloading, delays the provision of safe transfusion, and reduces health-related quality of life. Materials and Methods: In t...

Background: The development of anti-red blood cell alloantibodies remains a major problem in transfusion of blood in thalassemia major patients. Also, Autoantibodies can result in clinical hemolysis and difficulty in cross-matching blood. We studied the frequency of red blood cell alloimmunization and autoimmunization among thalassemia patients who received regular transfusions in Ilam province...

Red blood cell (RBC) clearance is known to occur primarily in the spleen, and is presumed to be executed by red pulp macrophages. Erythrophagocytosis in the spleen takes place as part of the homeostatic turnover of RBCs to remove old RBCs. It can be strongly promoted by immunoglobulin G (IgG) opsonization of RBCs, a condition that can occur as a consequence of autoantibody or alloantibody forma...

Myasthenia gravis (MG) is mediated by autoantibodies to the acetylcholine receptor (AChR), expressed in muscle and rare thymic myoid cells. Most early-onset cases show thymic lymph node-type infiltrates, including pre-activated plasma cells spontaneously producing anti-AChR antibodies. Since these are not evident in the associated thymomas found in another 10% of MG patients, AChR-specific B ce...

BACKGROUND/AIMS Lupus nephritis is an organ manifestation of systemic autoimmunity. Current treatment algorithms are still based on unselective immunosuppressive drugs. There is hope that highly selective biological drugs could be as or even more effective but less toxic. A profound understanding of the pathogenesis of lupus nephritis is necessary to identify the optimal molecular targets. ME...
