Update on idiopathic inflammatory myopathies.
The inflammatory myopathies are a group of acquired diseases, characterized by an inflammatory infiltrate of the skeletal muscle. On the basis of clinical, immuno-pathological and demographic features, three major diseases can be identified: dermatomyositis (DM); polymyositis (PM); and inclusion body myositis (IBM). New diagnostic criteria have recently been introduced, which are crucial for discriminating between the three different subsets of inflammatory myopathies and for excluding other disorders. DM is a complement-mediated microangiopathy affecting skin and muscle. PM and IBM are T cell-mediated disorders, where CD8-positive cytotoxic T cells invade muscle fibres expressing MHC class I antigens, thus leading to fibre necrosis. In IBM, vacuolar formation with amyloid deposits are also present. This article summarizes the main clinical, laboratory, electrophysiological, immunological and histologic features as well as the therapeutic options of the inflammatory myopathies.

Clinical implications of autoantibody screening in patients with autoimmune myositis.
OBJECTIVE: To evaluate the clinical usefulness of serum autoantibody profiling in patients with autoimmune myositis. METHODS: We retrospectively studied 74 consecutive patients: 68 had definite or probable myositis according to Bohan-Peter criteria, six suffered from antisynthetase syndrome with subclinical myopathy. Myositis specific antibodies (MSA) (anti-ARS, -SRP, -Mi-2) were determined by RNA immunoprecipitation or immunoblot, myositis associated antibodies (MAA) (anti-RoRNP, -U1RNP, -PM/Scl, -Ku) by immunoblot. RESULTS: Forty-three patients (58%) were positive for MSA: anti-Jo-1 in 15/27 polymyositis (PM) (55%), 4/33 dermatomyositis (DM) (12%), 1/8 overlap (12%) and 2/6 antisynthetase syndrome (33%); anti-ARS non-Jo-1 in 1/27 PM (4%), 2/33 DM (6%) and 4/6 antisynthetase syndrome (67%); anti-Mi-2 in 1/27 PM (4%) and 11/33 DM (33%); anti-SRP in 3/27 PM (11%) and 1/33 DM (3%). One patient was anti-Jo-1/Mi-2 positive, one anti-Jo-1/SRP positive. Moreover, 27 patients (36%) were positive for MAA: anti-Ro/SSA in 8/27 PM (30%), 7/33 DM (21%), 1/8 overlap (12%), and 3/6 antisynthetase syndrome (50%); anti-U1RNP in 1/27 PM (3.7%), 1/33 DM (3%), and 2/8 overlap (25%); anti-PM/Scl in 2/8 overlap (25%), anti-Ku in 2/8 overlap (25%). Anti-Jo-1 was predominantly associated with PM, anti-Mi-2 was almost exclusively found in DM patients. Anti-ARS antibodies were closely associated with interstitial lung disease and polyarthritis; notably, anti-ARS non-Jo-1 was more frequent in patients without overt muscle alterations. Anti-Ro/SSA antibody was not associated with any disease subset, but significantly more frequent in antisynthetase syndrome. CONCLUSIONS: Searching for MSA and MAA in patients with autoimmmune myositis is recommended because of its diagnostic and clinical value. Anti-ARS non-Jo-1 antibodies seem to preferentially target patients with pulmonary fibrosis without overt myopathy.

Autoantibody profile during short-term infliximab treatment for Crohn's disease: a prospective cohort study.
BACKGROUND: The potential clinical implications of autoimmunity during treatment with infliximab are unclear. AIM: To determine the frequency and correlation of autoantibody formation in patients with Crohn's disease treated with infliximab in a routine clinical setting. METHODS: Sixty-three patients with refractory/inflammatory (31) and/or fistulising Crohn's disease (32), received an infliximab infusion at a dose 5 mg/kg in weeks 0, 2 and 6, and were evaluated for the development of antinuclear, anti-double-stranded DNA, anti-Sm, anti-RNP, anti-SSA, anti-SSB and antihistone antibodies. The correlates with pharmacological treatments, the response to infliximab and adverse events were evaluated. RESULTS: Antinuclear antibodies were found in five of the 63 patients (8%) at baseline and in 26 (42%) after 10 weeks (P < 0.001). Of the 26 antinuclear antibody-positive patients who were further subtyped, nine of 63 (17%) had anti-double-stranded DNA (P = 0.003), and 1.5% were extractable nuclear antigen (ENA) and antihistone-positive. Five patients were initially positive for anticardiolipin antibodies and two more patients became positive during infliximab treatment. New autoantibody formation was more frequent in the patients with inflammatory/refractory disease than in those with fistulising disease (17 vs. 7; P = 0.02). One patient developed drug-induced lupus without major organ damage. CONCLUSIONS: Autoantibody formation occurs in 42% of patients (8% of these patients were positive before infliximab treatment) with Crohn's disease receiving induction treatment with infliximab, but the clinical significance of this remains to be determined.

Tumour necrosis factor alpha is expressed in refractory skin lesions from patients with subacute cutaneous lupus erythematosus.
OBJECTIVES: To investigate whether tumour necrosis factor alpha (TNFalpha) is expressed in subacute cutaneous lupus erythematosus (SCLE) skin lesions. METHODS: The in situ expression of TNFalpha in refractory lesional and non-lesional skin biopsy specimens from patients with SCLE was analysed using an immunohistochemical approach. At the time of biopsy these patients were receiving treatment with systemic medications such as antimalarial agents, immunosuppressive drugs, and thalidomide. Expression of TNFalpha was also evaluated in cutaneous lesions of patients with other inflammatory and neoplastic skin diseases as controls. RESULTS: The data showed that refractory lesional skin tissue from patients with SCLE displays a strongly positive distribution of TNFalpha, particularly within the epidermis. No prominent staining was seen in non-lesional skin from the same group of patients or in cutaneous lesions from the control group. CONCLUSIONS: These findings suggest that TNFalpha is localised and produced by epidermal cells within SCLE skin lesions and support its potential role in the pathogenesis of SCLE. The tissue localisation of TNFalpha may represent a potential therapeutic target providing a new perspective in the treatment of refractory skin lesions in patients with SCLE.

Anti-TNF antibody treatment improves glucocorticoid induced insulin-like growth factor 1 (IGF1) resistance without influencing myoglobin and IGF1 binding proteins 1 and 3.
BACKGROUND: Insulin-like growth factor 1 (IGF1) is an important determinant of muscle mass because it promotes growth and suppresses protein degradation. IGF1 is decreased in rheumatoid arthritis and juvenile idiopathic arthritis because its synthesis is inhibited by inflammation. In parallel, glucocorticoids induce IGF1 resistance and add to muscle degradation. OBJECTIVE: To investigate the influence of anti-tumour necrosis factor antibody treatment (anti-TNF) with adalimumab on levels of myoglobin (degradation marker) and IGF1 in patients with rheumatoid arthritis with and without prednisolone treatment. METHODS: Subcutaneous adalimumab was given to 32 patients with longstanding rheumatoid arthritis (16 with and 16 without prednisolone) in a longitudinal study. IGF1, IGF1 binding protein 1 (IGFBP-1), IGFBP-3, and myoglobin were measured by enzyme linked immunosorbent assay. RESULTS: Rheumatoid patients had normal serum myoglobin. Patients on prednisolone had higher myoglobin than patients not receiving prednisolone, indicating increased muscle degradation. On treatment with anti-TNF, myoglobin levels did not change in either patient group. Serum IGF1 was increased in patients with v without prednisolone, indicating IGF1 resistance (mean (SEM): 221 (23) v 122 (14) microg/l, p<0.001). Adalimumab treatment decreased the raised IGF1 levels in patients with prednisolone, so that after 12 weeks of treatment they reached the level of patients without prednisolone. Serum IGFBP-1 and IGFBP-3 did not differ in the two groups, and anti-TNF did not change these concentrations. CONCLUSIONS: Anti-TNF antibody treatment over 12 weeks improved glucocorticoid induced IGF1 resistance without influencing myoglobin and IGF1 binding proteins. Thus, in rheumatoid patients on glucocorticoids with generally decreased muscle mass anti-TNF treatment with adalimumab has favourable effects.

Increase of sympathetic outflow measured by neuropeptide Y and decrease of the hypothalamic-pituitary-adrenal axis tone in patients with systemic lupus erythematosus and rheumatoid arthritis: another example of uncoupling of response systems.
OBJECTIVE: To study in parallel the outflow of the sympathetic nervous system (SNS) and the hypothalamic-pituitary adrenal (HPA) axis tone in systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). METHODS: 32 patients with SLE, 62 with RA, and 65 healthy subjects (HS) were included. To measure the tone of the HPA axis, plasma ACTH and serum cortisol were determined. Serum neuropeptide Y (NPY) was used to evaluate the sympathetic outflow. RESULTS: Patients with SLE had increased NPY levels in comparison with HS, irrespective of prior prednisolone treatment (p<0.001). For patients with RA, only those with prednisolone treatment had increased NPY levels in comparison with HS (p = 0.016). Daily prednisolone dose correlated positively with serum NPY in RA (R(Rank) = 0.356, p = 0.039). In contrast, plasma ACTH levels were generally decreased significantly in comparison with HS in SLE with prednisolone, and in RA with/without prednisolone. Similarly, serum cortisol levels were also decreased in SLE with/without prednisolone, and in RA with prednisolone. The NPY/ACTH ratio was increased in SLE and RA, irrespective of prior prednisolone treatment. The NPY/cortisol ratio was increased in SLE with/without prednisolone, and in RA with prednisolone. Twelve weeks' anti-TNF antibody treatment with adalimumab did not decrease NPY levels in RA, irrespective of prednisolone treatment. CONCLUSIONS: An increased outflow of the SNS was shown and a decreased tone of the HPA axis in patients with SLE and RA. Low levels of cortisol in relation to SNS neurotransmitters may be proinflammatory because cooperative anti-inflammatory coupling of the two endogenous response axes is missing.

Anti-tumour necrosis factor antibody treatment does not change serum levels of cortisol binding globulin in patients with rheumatoid arthritis but it increases androstenedione relative to cortisol.
BACKGROUND: Cortisol binding globulin (CBG) is produced by liver cells and is inhibited by proinflammatory cytokines such as interleukin (IL) 6. CBG serum levels are typically low during prolonged inflammatory processes. Thus, observed changes of cortisol during anti-tumour necrosis factor (TNF) treatment may be related to changes of CBG in rheumatoid arthritis (RA). OBJECTIVE: To investigate the course of CBG during anti-TNF treatment in RA. METHODS: 13 patients with longstanding RA, without prior prednisolone treatment, were included in this longitudinal study with subcutaneous adalimumab. RESULTS: Treatment with anti-TNF markedly decreased clinical markers of inflammation and serum IL6. Serum levels of cortisol, CBG, and the ratio of cortisol/CBG did not change markedly, whereas the ratio of serum CBG/IL6 increased (p = 0.004). In parallel, levels of adrenocorticotropic hormone decreased during the observation period. The ratio serum androstenedione/serum cortisol increased during the study (p = 0.036). CONCLUSIONS: During anti-TNF treatment relatively normal levels of CBG and a normal ratio of CBG/cortisol are found. Changes of cortisol in relation to IL6 during anti-TNF treatment, seen previously, may not be related to changes of CBG.

Positive and negative effects of thalidomide on refractory cutaneous lupus erythematosus.
BACKGROUND: Thalidomide is used in cutaneous lupus erythematosus (CLE) refractory to conventional therapies. Peripheral neuropathy (PN) is the most severe side effect, but the incidence of PN and its relation to thalidomide dose are still unclear. OBJECTIVE: To prospectively evaluate the efficacy as well as the occurrence of PN in CLE patients treated with thalidomide, and to assess whether PN, when occurs, correlates with thalidomide dose and/or length of treatment. METHODS: Fourteen female patients with CLE in low-dose thalidomide therapy were followed for up to 24 months. Prior to, and regularly during treatment patients underwent rheumatological, dermatological, neurological and electrophysiological evaluations. A decline in sural SNAP of 50% or more from baseline value was considered as criterion of sensory axonal PN. RESULTS: All patients showed a dramatic improvement of skin manifestations. Ten patients (71.4%) developed a sensory axonal PN. The median time free from this complication was 14 months. No correlations were found between age of the patients nor thalidomide cumulative dose and occurrence of PN (Mann-Whitney U Test; p>0.16). Other adverse effects were: tremor, paresthesias, somnolence, amenhorrea, constipation and thoracic pain. CONCLUSIONS: Low does thalidomide is efficacious in treating CLE, but PN is a common complication whose occurrence does not seem to correlate with total thalidomide dose, whereas with the duration of therapy. A closer electrophysiological follow-up is therefore recommended in the long-term treatment.

Cardiac involvement in systemic lupus erythematosus.
Pericarditis is the most common cardiac abnormality in systemic lupus erythematosus (SLE) patients, but lesions of the valves, myocardium and coronary vessels may all occur. In the past, cardiac manifestations were severe and life threatening, often leading to death. Therefore, they were frequently found in post-mortem examinations. Nowadays cardiac manifestations are often mild and asymptomatic. However, they can be frequently recognized by echocardiography and other noninvasive tests. Echocardiography is a sensitive and specific technique in detecting cardiac abnormalities, particularly mild pericarditis, valvular lesions and myocardial dysfunction. Therefore, echocardiography should be performed periodically in SLE patients. Vascular occlusion, including coronary arteries, may develop due to vasculitis, premature atherosclerosis or antiphospholipid antibodies associated with SLE. Premature atherosclerosis is the most frequent cause of coronary artery disease (CAD) in SLE patients. Efforts should be made to control traditional risk factors as well as all other factors which could contribute to atherosclerotic plaque development.

Behçet's disease and cardiovascular involvement.
Behcet's disease (BD) is a multisystem disease of unknown etiology characterized by chronic relapsing orogenital ulcers, uveitis and systemic involvement including articular, gastrointestinal, cardiopulmonary, neurological and vascular pathology. The incidence and nature of cardiac involvement are not clearly elucidated. Cardiovascular manifestations have been reported in 7-46% of patients and mortality occurs in up to 20% of those patients with marked vascular involvement. Sporadic cases of endocarditis, myocarditis, pericarditis, acute myocardial infarction, aortic aneurysm, ventricular thrombosis, congestive cardiomyopathy and valvular dysfunction have been reported. This review discusses the general aspects of the pathogenic mechanisms and clinical features cardiovascular involvement in BD, and provides the data of cardiovascular involvement in a cohort of Italian BD patients.

Cardiac imaging techniques in systemic autoimmune diseases.
Systemic autoimmune disorders are frequently associated to cardiac involvement and to a high prevalence of ischemic coronary events, often occurring at a younger age than in the normal population. Large increase in mortality is related to premature atherosclerosis with coronary artery disease and stroke in patients with connective tissue diseases. Coronary heart disease is responsible for 40-50% of the deaths of patients with rheumatoid arthritis. Transesophageal or transthoracic echocardiography are the most useful and noninvasive techniques able to detect not only valvular abnormalities, embolic sources or pulmonary hypertension, but also left ventricular systolic or diastolic dysfunction. Furthermore, the introduction of new indexes, contrast agents and software increased the accuracy of this technique. It is possible now to evaluate coronary flow reserve by transthoracic echocardiography in patients with systemic autoimmune disease in order to detect microvasculature disorder. However, an ischemic response in a symptomatic patient requires, in most cases, further evaluation with cardiac catheterization. Coronary artery imaging allows confirmation of the presence, extent and position of atheromatous lesions. More recently, other imaging modalities including magnetic resonance and computerized tomography angiography have been developed to allow imaging of the coronary arteries.

Tumor necrosis factor-alpha, biologic agents and cardiovascular risk.
The increased risk of premature cardiovascular disease (CVD) in rheumatoid arthritis (RA) patients may depend on traditional risk factors but may also be attributable to RA-specific risk factors such as disease-related dyslipidemia, or cytokines such as tumor necrosis factor-alpha (TNF-alpha). TNF-alpha is a proinflammatory cytokine that can produce widespread deleterious effects when expressed in large amounts. It is produced in the heart by both cardiac myocytes and resident macrophages under conditions of cardiac stress, and is thought to be responsible for many of the untoward manifestations of cardiac disease. TNF-alpha may play a role in the triggering and perpetuation of atherosclerosis. Treatment with biologic agents directed against TNF-alpha has significant clinical benefits in inflammatory diseases such as RA and may be able to reduce cardiovascular risk. The disappointing results of the recent studies to antagonize TNF-alpha in CVD may have various explanations. However, the effects of TNF-alpha blockers on incident cases of congestive heart failure (CHF) in RA remains controversial. Due to the lack of evidence of a beneficial effect of anti-TNF-alpha agents in treatment of CHF, they should not be used to treat patients with New York Heart Association (NYHA) class III or IV heart failure.

[Complementary medicine in rheumatoid arthritis].
Use of complementary and alternative medicine (CAM) for chronic conditions has increased in recent years. CAM is immensely popular for musculoskeletal conditions and patients suffering from rheumatoid arthritis (RA) frequently try CAM. This review summarises the trial data for or against CAM as a symptomatic treatment for rheumatoid arthritis. Collectively the evidence demonstrates that some CAM modalities show significant promise, e.g. acupuncture, diets, herbal medicine, homoeopathy, massage, supplements. However, for the great majority of these therapies no evidencebased (clinical randomised trials) results are available. CAM is usually used in addition to, and not as a substitute for conventional therapies. The motivation of patients to try CAM is complex; the willingness to take control of their healthcare, the desire to try everything available, the mass-media pressure and the erroneous notion that CAM is without risks. In fact, none of these treatments is totally devoid of risks. While the use of complementary and alternative modalities for the treatment of RA continues to increase, rigorous clinical trials examining their efficacy are needed before definitive recommendations regarding the application of these modalities can be made.

Health-related quality of life in Italian patients with systemic lupus erythematosus. I. Relationship between physical and mental dimension and impact of age.
OBJECTIVE: To examine health-related quality of life (HRQOL) in Italian patients with systemic lupus erythematosus (SLE) and compare it with that of healthy people, and to investigate relationships among different dimensions and subscales of a generic health status measure. METHODS: The Medical Outcomes Study Short Form-36 (SF-36) was applied in a cohort of 126 consecutive SLE patients and 96 healthy controls. At the time of HRQOL testing, all patients underwent clinical and laboratory evaluation. RESULTS: Both physical (PCS) and mental (MCS) component summary scores of the SF-36 were reduced in patients compared with controls. In SLE great variability in all the subscales was observed. Significant correlations between PCS and MCS and between many different subscales were observed in patients but not in controls. The PCS was higher than MCS more frequently in controls than in SLE patients (81 vs 48.4%, P<0.00001). In SLE, HRQOL tended to worsen with age. CONCLUSION: Both PCS and MCS contribute to the decrease in HRQOL in SLE patients. In SLE the mutual interaction between these two dimensions seems to be more relevant than in healthy people.

The Italian version of the Fibrofatigue Scale, a reliable tool for the evaluation of fibromyalgia symptoms.
OBJECTIVE: To validate a translated Italian version of the Fibrofatigue Scale (FFS). METHODS: The Italian version of FFS was administered to 60 patients affected by fibromyalgia (FM) (57 patients were interviewed again 10 days later) together with the Italian version of the Fibromyalgia Impact Questionnaire (FIQ), the Stanford Health Assessment Questionnaire (HAQ) and the Medical Outcome Survey Short Form-36 (SF-36). All patients were asked about the severity of pain today (10-cm visual analogue scale) and the duration of symptoms. Test-retest reliability was assessed using Spearman correlations. Internal consistency was evaluated with Cronbach's alpha of reliability. Construct validity of the FFS was evaluated by correlations among the FFS, the FIQ and the subscales of the SF-36. RESULTS: Mean duration of symptoms was 7.6 years, and mean age of participants was 56.3 years. Test-retest reliability was between 0.70 and 0.95 for the single items as well as for the total FFS and other components. Internal consistency was 0.90 for the overall FFS. Significant correlations were obtained between the FFS items and the SF-36. CONCLUSIONS: The Italian FFS is a reliable and valid instrument for detecting and measuring functional disability and symptoms severity in Italian patients with FM.
