Vaccination and Autoimmune Disease: What Is the Evidence?
REVIEW Review Vaccination and autoimmune disease: what is the evidence? David C Wraith, Michel Goldman, Paul-Henri Lambert As many as one in 20 people in Europe and North America have some form of autoimmune disease. These diseases arise in genetically predisposed individuals but require an environmental trigger. Of the many potential environmental factors, infections are the most likely cause. Microbial antigens can induce cross-reactive immune responses against self-antigens, whereas infections can non-specifically enhance their presentation to the immune system. The immune system uses fail-safe mechanisms to suppress infection-associated tissue damage and thus limits autoimmune responses. The association between infection and autoimmune disease has, however, stimulated a debate as to whether such diseases might also be triggered by vaccines. Indeed there are numerous claims and counter claims relating to such a risk. Here we review the mechanisms involved in the induction of autoimmunity and assess the implications for vaccination in human beings. Autoimmune diseases affect about 5% of individuals in Autoimmune disease and infection developed countries.1 Although the prevalence of most Human beings have a highly complex immune system autoimmune diseases is quite low, their individual that evolved from the fairly simple system found in incidence has greatly increased over the past few years, as invertebrates.

ANCA--Associated Small-Vessel Vasculitis
ANCA–Associated Small-Vessel Vasculitis ISHAK A. MANSI, M.D., PH.D., ADRIANA OPRAN, M.D., and FRED ROSNER, M.D. Mount Sinai Services at Queens Hospital Center, Jamaica, New York and the Mount Sinai School of Medicine, New York, New York Antineutrophil cytoplasmic antibodies (ANCA)–associated vasculitis is the most common primary sys- temic small-vessel vasculitis to occur in adults. Although the etiology is not always known, the inci- dence of vasculitis is increasing, and the diagnosis and management of patients may be challenging because of its relative infrequency, changing nomenclature, and variability of clinical expression. Advances in clinical management have been achieved during the past few years, and many ongoing studies are pending. Vasculitis may affect the large, medium, or small blood vessels. Small-vessel vas- culitis may be further classified as ANCA-associated or non-ANCA–associated vasculitis. ANCA–asso- ciated small-vessel vasculitis includes microscopic polyangiitis, Wegener’s granulomatosis, Churg- Strauss syndrome, and drug-induced vasculitis. Better definition criteria and advancement in the technologies make these diagnoses increasingly common. Features that may aid in defining the spe- cific type of vasculitic disorder include the type of organ involvement, presence and type of ANCA (myeloperoxidase–ANCA or proteinase 3–ANCA), presence of serum cryoglobulins, and the presence of evidence for granulomatous inflammation. Family physicians should be familiar with this group of vasculitic disorders to reach a prompt diagnosis and initiate treatment to prevent end-organ dam- age. Treatment usually includes corticosteroid and immunosuppressive therapy. (Am Fam Physician 2002;65:1615-20.

Primary systemic vasculitides are rare diseases that may manifest similarly to more commonly encountered conditions. Depending on the size of the vessel affected (large vessel, medium vessel, or small vessel), different vasculitis mimics must be considered. Establishing the right diagnosis of a vasculitis mimic will prevent unnecessary immunosuppressive therapy. 1. Introduction 2.

Joint pain preceded diagnosis by up to three years in five patients and 15 years in one patient. Joints most commonly involved were lumbar spine, hips, and knees (four cases). In three cases there were no bowel symptoms. All were seronegative. X-rays were abnormal in two cases. HLA-type Al, B8, DR3 was present in five and B27 in two patients. Circulating immune complexes showed no consistent pattern before or after treatment. Coeliac disease was diagnosed in all patients by jejunal biopsy, and joint symptoms in all responded to a gluten-free diet. Gluten challenge (for up to three weeks) failed to provoke arthritis in three patients tested. In a separate study of 160 treated coeliac patients attending regular follow up no arthritis attributable to coeliac disease and no ankylosing was in a group spondylitis identified, though control of 100 patients with Crohn's disease thecopyright. expected incidence of seronegative polyarthritis (23%) and ankylosing spondylitis (5%) was found (p<0.01). -
Conditions Related to Inflammatory Arthritis
Conditions Related to Inflammatory Arthritis There are many conditions related to inflammatory arthritis. Some exhibit symptoms similar to those of inflammatory arthritis, some are autoimmune disorders that result from inflammatory arthritis, and some occur in conjunction with inflammatory arthritis. Related conditions are listed for information purposes only. • Adhesive capsulitis – also known as “frozen shoulder,” the connective tissue surrounding the joint becomes stiff and inflamed causing extreme pain and greatly restricting movement. • Adult onset Still’s disease – a form of arthritis characterized by high spiking fevers and a salmon- colored rash. Still’s disease is more common in children. • Caplan’s syndrome – an inflammation and scarring of the lungs in people with rheumatoid arthritis who have exposure to coal dust, as in a mine. • Celiac disease – an autoimmune disorder of the small intestine that causes malabsorption of nutrients and can eventually cause osteopenia or osteoporosis. • Dermatomyositis – a connective tissue disease characterized by inflammation of the muscles and the skin. The condition is believed to be caused either by viral infection or an autoimmune reaction. • Diabetic finger sclerosis – a complication of diabetes, causing a hardening of the skin and connective tissue in the fingers, thus causing stiffness. • Duchenne muscular dystrophy – one of the most prevalent types of muscular dystrophy, characterized by rapid muscle degeneration. • Dupuytren’s contracture – an abnormal thickening of tissues in the palm and fingers that can cause the fingers to curl. • Eosinophilic fasciitis (Shulman’s syndrome) – a condition in which the muscle tissue underneath the skin becomes swollen and thick. People with eosinophilic fasciitis have a buildup of eosinophils—a type of white blood cell—in the affected tissue. -

Tests for Autoimmune Diseases Test Codes 249, 16814, 19946 Frequently Asked Questions Panel components may be ordered separately. Please see the Quest Diagnostics Test Center for ordering information. 1. Q: What are autoimmune diseases? A: “Autoimmune disease” refers to a diverse group of disorders that involve almost every one of the body’s organs and systems. It encompasses diseases of the nervous, gastrointestinal, and endocrine systems, as well as skin and other connective tissues, eyes, blood, and blood vessels. In all of these autoimmune diseases, the underlying problem is “autoimmunity”—the body’s immune system becomes misdirected and attacks the very organs it was designed to protect. 2. Q: Why are autoimmune diseases challenging to diagnose? A: Diagnosis is challenging for several reasons: 1. Patients initially present with nonspecific symptoms such as fatigue, joint and muscle pain, fever, and/or weight change. 2. Symptoms often flare and remit. 3. Patients frequently have more than 1 autoimmune disease. According to a survey by the Autoimmune Diseases Association, it takes up to 4.6 years and nearly 5 doctors for a patient to receive a proper autoimmune disease diagnosis.1 3. Q: How common are autoimmune diseases? A: At least 30 million Americans suffer from 1 or more of the 80 plus autoimmune diseases. On average, autoimmune diseases strike three times more women than men. Certain ones have an even higher female:male ratio. Autoimmune diseases are one of the top 10 leading causes of death among women age 65 and under2 and represent the fourth-largest cause of disability among women in the United States.3 Women’s enhanced immune system increases resistance to infection, but also puts them at greater risk of developing autoimmune disease than men. -

10 Chronic Urticaria As an Autoimmune Disease
10 Chronic Urticaria as an Autoimmune Disease Michihiro Hide, Malcolm W. Greaves Introduction Urticaria is conventionally classified as acute, intermittent and chronic (Grea- ves 2000a). Acute urticaria which frequently involves an IgE-mediated im- munological mechanism, is common, its causes often recognised by the patient, and will not be considered further. Intermittent urticaria – frequent bouts of unexplained urticaria at intervals of weeks or months – will be dis- cussed here on the same basis as ‘ordinary’ chronic urticaria. The latter is conventionally defined as the occurrence of daily or almost daily whealing for at least six weeks. The etiology of chronic urticaria is usually obscure. The different clinical varieties of chronic urticaria will be briefly considered here, and attention will be devoted to a newly emerged entity – autoimmune chronic urticaria, since establishing this diagnosis has conceptual, prognostic and the- rapeutic implications. Contact urticaria and angioedema without urticaria will not be dealt with in this account. Classification of Chronic Urticaria The clinical subtypes of chronic urticaria are illustrated in the pie-chart of Fig. 1. The frequency of these subtypes is based upon the authors’ experience at the St John’s Institute of Dermatology in UK. Whilst there may well be mi- nor differences, it is likely that the frequency distribution of these subtypes will be essentially similar in most centres in Europe and North America (Grea- ves 1995, 2000b). However, our experience suggests that the incidence of angioedema, especially that complicated by ordinary chronic urticaria is sub- stantially lower in Japan and south Asian countries (unpublished observation). 310 Michihiro Hide and Malcolm W.
