Thyroid autoimmunity, as reflected by the presence in serum of autoantibodies directed against the thyroid autoantigens thyroglobulin (Tg) and thyroid peroxidase (TPO), is present in >10% of the US population over 12 years of age [1] and is the most common cause of endocrine dysfunction in iodine-sufficient populations [2]. The underlying mechanism is a failure of T-cell tolerance leading to ly...

The etiopathogenesis of many autoimmune disorders has not been identified. The aim of this paper is to focus on the involvement of bacterial exposure in the pathogenesis of primary biliary cirrhosis (PBC) and autoimmune pancreatitis (AIP), both of which are broadly categorized as autoimmune disorders involving hepatobiliary-pancreatic lesions. Avirulent and/or commensal bacteria, which may have...

BACKGROUND Posttraumatic stress disorder (PTSD) is associated with endocrine and immune abnormalities that could increase risk for autoimmune disorders. However, little is known about the risk for autoimmune disorders among individuals with PTSD. METHODS We conducted a retrospective cohort study of 666,269 Iraq and Afghanistan veterans under age 55 who were enrolled in the Department of Veter...

BACKGROUND Hematopoietic stem cell transplantation (HSCT) remains the only curative treatment for many nonmalignant disorders, such as autoimmune disorders, inborn metabolic disorders, hemoglobinopathies, and immunodeficiency disorders. Autoimmune complications (AICs) after HSCT, such as autoimmune cytopenias, autoimmune hepatitis, primary biliary cirrhosis, and autoimmune cutaneous manifestati...

premature ovarian failure (pof) is a heterogeneous syndrome with several causative factors. autoimmune mechanisms are involved in pathogenesis of 4-30 % of pof cases. the present review focuses on the role of autoimmunity in the pathophysiology of pof. the evidences for an autoimmune etiology are: demonstration of ovarian autoantibodies, the presence of lymphocytic oophoritis, and association w...

high cortisol level in endogenous cushing’s syndrome suppresses the immune system and after treatment there may be an over activity of immune reaction leading to autoimmune diseases mostly thyroid and rheumatologic disorders. this is the second reported case of multiple sclerosis developing after treatment of cushing’s syndrome. a 42-year old man is reported who presented with bone fracture and...

Hundred patients of vitiligo of any age and either sex, diagnosed on the basis of history and clinical examination were enrolled from the outpatient department. Patients were evaluated f...

Background: Ataxia telangiectasia (AT) is one of the combined immunodeficiency syndromes with immunologic, neurologic, endocrinologic, hepatic and cutaneous abnormalities. Regarding the fact that autoimmune disorders; such as autoimmune hemolytic anemia (AIHA), are not generally expected in the course of AT, we present a patient with an unusual presentation of these two conditions. Case present...

BACKGROUND It is a hospital based study focusing on epidemiological aspects of vitiligo and association with autoimmune disorders. There are few studies elucidating the association of autoimmune disorders with vitiligo in the Indian population. Our study is a small attempt in this direction. AIM To study epidemiological parameters of vitiligo and to study coexistence of autoimmune disorders. ...
