Corticosteroids form the basis of treatment in many inflammatory rheumatic diseases, both as systemic treatment and as treatment with local injections to reduce inflammation. In 1948 the first systemic treatment of a patient with a rheumatic disease was given to a woman with severe rheumatoid arthritis (RA); the impressive effect in this patient, and in another 15 patients, was reported by Dr Hench and co-workers in 1949. Systemic corticosteroid treatment was rapidly adopted and used not only for patients with RA but also for those with other rheumatic diseases such as systemic lupus erythematosus-as well as other disorders such as asthma-with a similar positive effect. In the following year, 1950, the Nobel Prize was awarded for the discovery of the structure and biological effects of the adrenal cortex hormones. This open trial was followed by several controlled trials conducted in the UK in which the effects of cortisone were compared with the effects of aspirin in patients with RA-interestingly, without any significant clinical benefit for the cortisone-treated patients. It was not until 1959, in yet another multi-centre trial in Britain, that a significant effect on functional capacity and general well-being was reported after 2 years of treatment with prednisolone, compared to aspirin, in patients with early RA. Despite the dramatic effects that were observed in the severely ill RA patients reported by Hench and co-workers it took 10 years to demonstrate that this effect was superior to the effect of aspirin when the two compounds were compared in controlled trials. Why was this so? One explanation could be in the study designs and the different outcome measures used in the various studies. Perhaps the results in the first comparative studies would have been different if individual response criteria had been used. This is discussed in this chapter.

There are a number of pathological conditions in which tissue damage occurs in association with immune activation directed against components of normal tissue. The initial damaging events usually involve cells of the immune system, the T-cells, but the cell damage releases antigens that become targets for an antibody response. The detection and quantification of autoantibodies has become an important component in the diagnosis and management of autoimmune rheumatic diseases such as rheumatoid arthritis, systemic lupus erythematosus, the systemic vasculitides and systemic sclerosis. Each of these diseases is associated with a particular autoantibody or group of autoantibodies. They are usually detected by their reaction against tissue components using subjective methods such as indirect immunofluorescence. Any positive samples are further analysed using more specific and quantitative methods for the 'quantification' of the specific autoantibody concentration. It is important that these autoantibodies are not considered to be 'gold standard' tests: they are no more than markers of the disease with significant limitations. They are best used as part of a diagnostic panel rather than as a marker indicating one particular disease. Techniques are gradually improving, giving numerical results rather than titres, but a lack of standardization makes these results extremely variable. Many of the markers show no correlation with disease activity. Their use should be restricted to the initial investigation and not repeated every time the patient is followed up. Other markers do, however, correlate with disease activity and can be used to monitor disease. When investigating patients who have symptoms associated with autoimmune rheumatic diseases, analytes such as immunoglobulins, complement components and C-reactive protein may all be measured.

The paediatric idiopathic inflammatory myopathies (IIMs) are a group of rare but serious systemic autoimmune conditions of childhood. The most common of the paediatric IIMs is juvenile dermatomyositis (JDM), while polymyositis and inclusion body myositis are rare in children. JDM has a significantly different spectrum of disease from adult dermatomyositis. Juvenile myositis can also occur as part of other systemic autoimmune diseases such as scleroderma and systemic lupus erythematosus. There has recently been significant progress towards the development and validation of tools to measure disease activity and damage in the paediatric IIMs. In addition, several new therapeutic avenues have been used to treat JDM. This review will discuss developments in the diagnostic criteria for JDM, the clinical types and course of these conditions, recent progress in disease assessment, treatment options and new developments in research into the pathogenesis of paediatric IIM.

Until about 15 years ago, the general advice to women with autoimmune rheumatic diseases, especially systemic lupus erythematosus, systemic sclerosis and vasculitic syndromes, was to avoid pregnancy as there was a high risk of maternal and fetal morbidity and mortality. However, it is now clear that these risks can be reduced in general by avoiding pregnancy when the diseases are active and continuing appropriate medication to reduce the chances of disease flare during pregnancy. This article will review the evidence for this advice and will also consider other issues that should be discussed with women before they attempt to become pregnant. This will include the influence of pregnancy on the individual autoimmune diseases, as well as the potential impact of the diseases and drug therapy on fertility and pregnancy outcomes. Anti-phospholipid antibody syndrome has emerged as a major cause of fetal loss, pre-eclampsia and premature birth. The clinical and laboratory diagnosis of this condition will not be covered, but the reader is referred to an excellent recent review. Much of the data on pregnancy and autoimmune rheumatic diseases come from retrospective analyses, but some prospective studies have been reported over the past 10 years. There have been very few meta-analyses or randomized clinical trials.

Renal involvement is relatively common in certain systemic autoimmune diseases, but can be clinically silent. Active surveillance is, therefore, essential because the early recognition of renal involvement may influence the extent of renal recovery. Blood pressure control is also essential, regardless of the underlying disease. In systemic lupus erythematosus, therapy usually depends on the renal biopsy findings as not all forms of renal involvement respond in the same way. Typically, for aggressive disease, therapy is with steroids and a cytotoxic agent, usually cyclophosphamide initially and then azathioprine. In systemic vasculitis with renal involvement, a similar approach is adopted, therapy including steroids and cyclophosphamide initially and then steroids and azathioprine. With severe fulminant disease, plasma exchange or pulsed intravenous methylprednisolone is added initially. Scleroderma renal crises are managed by blood pressure control using angiotensin-converting enzyme inhibitors and other agents as required. Dialysis and transplantation can be successful in these conditions.

Systemic lupus erythematosus is a heterogeneous, multisystem disease responsive to treatment with corticosteroids and immune suppressives. Many patients fail to achieve treatment-free remissions, and their long-term outcomes remain poor owing to the development of vital organ failure, cumulative drug toxicity and an increased risk of cardiovascular disease and malignancy. Haematopoietic stem cell transplantation (HSCT) offers the potential to improve long-term outcome in those with a poor prognosis. Preliminary phase II and registry studies have usually employed non-myeloablative conditioning with positive CD34 cell selection. They have highlighted the potential efficacy and dangers of HSCT. Patient selection is important but complex, and the influence of HSCT on long-term outcome is unknown. Disease relapse occurs in up to one-third of patients after HSCT, but the consequences of relapse and the role of remission-maintenance strategies are unknown. With the availability of other alternative therapies in refractory disease, there needs to be a clear demonstration of the benefits of HSCT from current randomized trials.

Drug induced autoimmune syndromes have been recognized for many years. The classical presentation is that of drug-induced lupus, a generally milder version of the idiopathic disorder that is associated with production of antihistone antibodies. This pattern is now changing, in part due to the many new drugs that have been introduced into clinical practice for treatment of autoimmune diseases, including both conventional pharmaceuticals and biologicals. The number and complexity of drug-induced autoimmune syndromes has increased, and many are now associated with autoantibodies that have been classically defined as limited to idiopathic disease states. Furthermore, some of these drug-induced syndromes have life-threatening complications, so that recognition of drug-induced disease has become more difficult at a time when it is more urgent to establish a correct diagnosis. Many reports are limited to case descriptions, and few controlled investigations have been carried out. Nevertheless, it is possible to derive an approach to considering possible mechanisms by which these processes may take place. This chapter will consider these proposed mechanisms, using some of the implicated drugs to illustrate possible pathogenetic pathways.

One foreign and two Russian recombinant enzyme immunoassay test-systems were comparatively investigated under conditions of an encoded experiment. Sensitivity in the experiment with the Russian test-systems Borreliosis-ELISA-IgG and Lyme Best was 63.8 and 68.8% respectively. As for the test-system Borrelia IgG Recombinant, it was 47.5%. All the test-systems were highly specific (94.4 to 99.5%). The test-systems Lyme Best and Borrelia IgG Recombinant revealed partial cross reactions with sera from patients with systemic lupus erythematosus and leptospirosis.

Autoimmune thyroid disease is frequently accompanied by other organ-specific and non-organ-specific diseases, most likely because there is sharing of genetic and possibly environmental susceptibility factors. These associations are well recognized in the autoimmune polyglandular syndromes; autoimmune thyroid disease is one of the three major endocrinopathies in the type 2 syndrome and occurs in around 4% of type 1 patients. This review considers the frequency of disease-specific autoantibodies in patients with thyroid autoimmunity and briefly examines the role of such antibodies in performing screening for the associated conditions. Recommendations are made for using such autoantibody tests in the setting of patients with autoimmune thyroid disorders, and also for the utility of screening for thyroid autoimmunity in patients with pernicious anaemia, Addison's disease, coeliac disease, primary biliary cirrhosis, myasthenia gravis, lymphocytic hypophysitis, systemic lupus erythematosus and rheumatoid arthritis. At present, however, there are no large-scale trials that have shown the cost-benefit ratio of autoantibody screening for autoimmunity screening, and clinicians must use individual judgement combined with heightened awareness to identify who to test.

Autoimmune diseases are most common and most active in young women; it is therefore not uncommon for obstetricians and physicians to encounter pregnant women with these conditions, and knowledge of the potential maternal, foetal and neonatal complications is essential for good clinical management. The most common maternal autoimmune endocrine conditions in pregnancy are insulin-dependent diabetes mellitus and thyroid disease. Other relatively common non-endocrine autoimmune conditions include systemic lupus erythematosus and anti-phospholipid syndrome. Much rarer autoimmune conditions include autoimmune thrombocytopenia, rheumatoid arthritis, myasthenia gravis and Addison's disease. In this chapter, we discuss autoimmune endocrine conditions and briefly mention some non-endocrine conditions of particular importance.
