Although systemic lupus erythematosus (SLE) is indeed a complex autoimmune disease, recent advances in our understanding of lupus pathogenesis have suggested new, targeted approaches to therapy. The purpose of this review is to discuss the underlying scientific rationale and results of first clinical studies of new treatment approaches to SLE, with a focus on cell-depleting therapies and cytokine blockade. It has become clear that the B lymphocyte plays a key role in disease pathogenesis by both autoantibody-dependent and autoantibody-independent mechanisms. Additionally, aberrant interactions between B and T cells are critical to disease emergence and progression. New agents that directly target immune cells abnormal in SLE include the B-cell depleting or modulating antibodies, rituximab (anti-CD20) and epratuzumab (anti-CD22) and the anti-dsDNA tolerogen LJP394. Another promising approach has been to block co-stimulatory interactions between T and B cells, for example by inhibiting the CD40-CD40 ligand pathway with anti-CD40 ligand monoclonal antibody or the B7 pathway with CTLA-4Ig. Immune cells can also be manipulated indirectly through cytokine effects. For B cells, anti-BAFF (B-cell activation factor of the tumor necrosis family) provides an example of this approach. Other, more pleiotropic cytokines can likewise be blocked in SLE. In addition to the blockade of interleukin-10 (IL-10), the first anti-cytokine approach examined, it is mainly anti-tumor necrosis factor therapy that has come into focus, holding promise for some patients with lupus nephritis. The majority of the available data on these new treatment approaches stems from open-label trials, but controlled trials are under way. Moreover, many additional cytokines, such as interleukin (IL)-6, IL-18, and the type I interferons, represent interesting future targets.

Secondary osteoporosis is common among patients being evaluated for osteoporosis. All men and premenopausal women with unexplained bone loss or a history of a fragility fracture should undergo a work-up for secondary osteoporosis. Also, postmenopausal women with risk factors for secondary osteoporosis should be carefully evaluated. The evaluation should include a thorough history, physical examination, bone mineral density testing, and laboratory testing. While there is no consensus for a cost-effective laboratory evaluation, some recommendations include: 25-hydroxyvitamin D, parathyroid hormone (PTH), serum and urine calcium, phosphate, creatinine, liver function tests, a complete blood count, testosterone in men, and thyroid-stimulating hormone. After a thorough review of the evaluation for secondary osteoporosis, this chapter reviews the pathophysiology and treatment of secondary osteoporotic disorders, including vitamin D insufficiency, osteomalacia, the osteoporosis of erosive inflammatory arthritis, ankylosing spondylitis, systemic lupus erythematosus, and osteoporosis related to anti-androgenic therapy for prostate cancer and aromatase inhibitor therapy for breast cancer. Physicians have a significant responsibility to evaluate and treat the underlying medical problem that is the cause of secondary osteoporosis and to optimize bone health in the individual patient.

This chapter aims to give a global perspective to paediatric rheumatology. The main points covered are the incidence, recognition of paediatric autoimmune diseases, and ethnic/geographic distribution. The most prevalent disease is juvenile idiopathic arthritis; robust data are still required for childhood-onset systemic lupus erythematosus, dermatomyositis, and scleroderma. Mimicking or overlapping infections are a major challenge in developing countries, and immunization policies in our patients in these areas need specific attention. The delivery of paediatric rheumatology care is also overviewed. Discrepancies in health-care resources and priorities are found in developing countries. Although most anti-rheumatic treatments are available worldwide, they are prohibitively expensive in many countries. For more traditional anti-rheumatic drugs there is still an ongoing need for good core outcome data across the world to ensure valid comparisons. Parent/patient education has been implemented worldwide in paediatric rheumatology through the power of the Internet. Physician and undergraduate training goals must be met to facilitate competent musculoskeletal assessment, a proper understanding of age-dependent variations, diagnosis, referral to specialists, and improved standards of care.

Adolescence is a time of profound biological and psychosocial change. The management of a complex chronic condition such as systemic lupus erythematosus (SLE) during this period is a challenging but rewarding task for the clinician. Early diagnosis and optimal disease control is essential in order to facilitate normal adolescent development and minimize long-term disease sequelae. Current treatment regimens are associated with significant toxicity in young people, and there is a need for new, less toxic regimens. There are currently no controlled therapeutic studies in adolescents with SLE. Those involved in the care of these young people must ensure that they have appropriate access to specialist medical services while ensuring that their specific needs as adolescents in the health-care system are addressed.

Management of pregnant women with renal disease involves awareness of, and allowance for, physiological changes including decreased serum creatinine and increased proteinuria. For women with systemic lupus erythematosus (SLE), pregnancy increases likelihood of flare. These can occur at any stage, and are more difficult to diagnose, as symptoms overlap those of normal pregnancy. Renal involvement is no more common in pregnancy. Worsening proteinuria may be lupus flare but differential includes pre-eclampsia. In women with chronic renal disease, pregnancy may accelerate decline in renal function and worsen hypertension and proteinuria, with increased risk of maternal (eg, pre-eclampsia) and fetal (eg, IUGR, IUD) complications, strongly correlating with degree of renal impairment peri-conception. Pregnancy success rate varies from 20% to 95% depending on base-line creatinine. Best outcome is obtained if disease was quiescent for >6 months pre-conception. Women on dialysis or with renal transplants can achieve successful pregnancy but have higher maternal and fetal complication rates. Acute on chronic renal failure can develop secondary to complications such as HELLP and AFLP. Management needs to be by a multidisciplinary team involving physicians and obstetricians, ideally beginning with pre-pregnancy counselling. Treatment of flares includes corticosteroids, hydroxychloroquine, azothioprine, NSAIDs and MME Blood pressure is controlled with methyldopa, nifedipine or hydralazine.

Women with systemic lupus erythematosus (SLE) face significant risks when embarking on a pregnancy, but attending a multidisciplinary clinic staffed by an experienced team can improve pregnancy outcome for women and their babies. Pregnancy in SLE should be planned and a management strategy should be agreed in full consultation with the patient, prior to conception. Pregnancy increases the likelihood of a lupus flare. It is not possible to predict when, or if, an individual patient will flare, although flare is more likely if disease has been active within 6 months of conception. Worsening of proteinuria in pregnancy could herald a lupus flare, but the differential diagnosis also includes the physiological response to pregnancy and pre-eclampsia. Corticosteroids, hydroxychloroquine and azathioprine are safe to use in pregnancy, with no adverse fetal effects reported despite many years of experience with their use. Correct identification of patients with antiphospholipid syndrome is important because treatment of affected women during pregnancy can improve fetal and maternal outcome. Neonatal SLE, although rare, carries a significant mortality and morbidity when the fetal heart is the targeted organ. Prophylaxis therapies, including treatment with intravenous immunoglobulin, await larger trials.

Many inflammatory, metabolic and infectious diseases affect the skin and joints. Most of these, such as rheumatoid arthritis and systemic lupus erythaematosus, are considered to be rheumatic conditions with secondary skin involvement. However, several primary cutaneous diseases are associated with arthritis and may even present with joint symptoms prior to cutaneous lesions. Common skin disorders, such as acne and psoriasis, have well-known musculoskeletal manifestations. Other less common conditions, such as dermatomyositis, multicentric reticulohistiocytosis, pyoderma gangrenosum, Sweet's syndrome and various cutaneous vasculitides, also have frequent joint involvement. This review will discuss the clinical presentation, both cutaneous and musculoskeletal, diagnosis and management of these disorders.

B cell depletion therapy was introduced for auto-antibody associated rheumatic disease in 1998. Encouraging pilot studies in rheumatoid arthritis were followed by randomised controlled trials confirming major benefit. Licensing for use in patients unable to benefit from tumour necrosis factor alpha (TNFalpha) neutralising agents is envisaged shortly. Open studies in other disorders, in particular systemic lupus erythematosus (SLE), have also suggested benefit and its use in life-threatening situations is becoming widespread. Toxicity appears to compare favourably with other agents, but respiratory problems may be more common. Repeated therapy is effective, but may lead to hypogammaglobulinemia. Rituximab is currently the main agent used but other agents are in development. Optimal protocols are not well characterised and will probably be different for different conditions.

The pandemic caused by the human immunodeficiency virus (HIV) has entered its second quarter-century, with 40 million people now affected worldwide - particularly in Africa, where the impact has been most devastating. A complex array of rheumatic disease manifestations has been described, including diseases specific to HIV infection such as HIV-associated arthritis and the diffuse infiltrative lymphocytosis syndrome; other conditions which occur prominently in HIV-positive individuals include vasculitis, reactive and psoriatic arthritis and HIV-associated polymyositis, opportunistic musculoskeletal infections, and finally disorders that were originally ameliorated by HIV infection, such as rheumatoid arthritis and lupus. Effective antiretroviral treatment ameliorates many of these disorders; however, the introduction of highly active antiretroviral treatment (HAART) has introduced a new spectrum of disorders and new challenges confronting the clinician, including osteonecrosis, rhabdomyolysis, and, with immune reconstitution, the appearance de novo of a variety of autoimmune disorders and phenomena.

Chronic pain is very common in all European countries, with musculoskeletal problems predominating. About 1% of the adult population develops a syndrome of chronic muscle pain, fibromyalgia (FMS), characterized by multiple tender points, back or neck pain, and a number of associated problems from other organs, including a high frequency of fatigue. Evidence points to central sensitization as an important neurophysiological aberration in the development of FMS. Importantly, these neurological changes may result from inadequately treated chronic focal pain problems such as osteoarthritis or myofascial pain. It is important for health professionals to be aware of this syndrome and to diagnose the patients to avoid a steady increase in diagnostic tests. On the other hand, patients with chronic widespread pain have an increased risk of developing malignancies, and new or changed symptoms should be diagnosed even in FMS. In rheumatology practice it is especially important to be aware of the existence of FMS in association with immune inflammatory diseases, most commonly lupus and rheumatoid arthritis. Differential diagnoses are other causes of chronic pain, e.g. thyroid disease. The costs of this syndrome are substantial due to loss of working capability and direct expenses of medication and health-system usage. Fibromyalgia patients need recognition of their pain syndrome if they are to comply with treatment. Lack of empathy and understanding by healthcare professionals often leads to patient frustration and inappropriate illness behavior, often associated with some exaggeration of symptoms in an effort to gain some legitimacy for their problem. FMS is multifaceted, and treatment consists of both medical interventions, with emphasis on agents acting on the central nervous system, and physical exercises.
