Non-specific rheumatic manifestations in patients with Hashimoto's thyroiditis: a pilot cross-sectional study.

PURPOSE: Hashimoto's thyroiditis (HT) is often associated with rheumatic disorders (arthritis, etc.), but many HT patients report non-specific rheumatic signs and symptoms in the absence of clinically evident rheumatic diseases. Aim of this study was to evaluate the prevalence of non-specific rheumatic manifestations (RMs) in HT subjects without classified autoimmune comorbidities. METHODS: 500 HT patients (467 F, 33 M; median age 41 years, range 14-69) and 310 age- and sex-matched controls, consecutively referred to the Endocrine Unit of Messina University Hospital, were evaluated for non-specific RMs. None took L-thyroxine. EXCLUSION CRITERIA: autoimmune comorbidities, infectious, and/or inflammatory diseases, history of neoplasia, BMI > 30 kg/m2. RESULTS: In our HT cohort, 100 patients (20%) complained of one or more RMs, vs 21 controls (6.8%; P < 0.001). There were minimal differences between the manifestations recorded in the two groups, the most common being polyarthralgias and myalgias/fibromyalgia, but non-specific RMs occurred threefold more in HT patients. Comparing HT patients with RMs (96 F and 4 M) with those affected by HT alone, female sex was prevalent (F:M ratio 24:1 vs 5:1) with higher age at diagnosis (median 43 vs 37 years; P < 0.001). HT patients with RMs (62%) were mostly euthyroid (median TSH 2.0 µIU/L) and only 7% overtly hypothyroid, discouraging a possible causal relationship between thyroid dysfunction per se and RMs. CONCLUSIONS: A significant percentage of HT patients complains of non-specific rheumatic signs and symptoms, in the absence of other diagnosed systemic comorbidities and regardless of thyroid functional status, deserving careful evaluation and prolonged follow-up.

New simplified protocols for timed artificial insemination (TAI) in milk-producing donkeys.

This study compared the outcome of two new timed artificial insemination (TAI) protocols in a milk-producing donkey farm. Ninety Amiata jennies were inseminated at the moment of ovulation induction with hCG, with fresh-transported semen that had been stored at room temperature from 3 up to 6 h, with an approximate average storage time of 4 h and a half. In both protocols, on Day 0 jennies were treated with alfaprostol (PGF2α), and on Day 7 they were checked by ultrasound (US) and, if in estrus, they were treated in order to induce ovulation and were then artificially inseminated. In the slow-short TAI protocol, jennies not already inseminated were treated again with PGF2α at Day 14. On day 21 US was repeated and estrus jennies were induced to ovulate and inseminated. In the fast-long TAI protocol, US was performed once a week in jennies not already inseminated and if found in estrus, they were induced to ovulate and inseminated, while those not in estrus were treated again with PGF2α. This protocol was repeated for up to nine weeks. The rates of inseminated/treated, pregnant/inseminated and pregnant/treated jennies were 76%, 56% and 43% for the slow-short TAI protocol and 94%, 47% and 44% for the fast-long TAI protocol. The age class and the lactation status of the jennies had no significant effect on synchronization success or final pregnancy rate. This study demonstrates that it is possible to achieve reasonable pregnancy rates through simplified TAI protocols in jennies, reducing animal handling to a minimum.

Effects of infliximab on sister chromatid exchanges and chromosomal aberration in patients with rheumatoid arthritis.

The aim of this study was to evaluate in a 24-weeks the effect of anti-TNF-alpha, infliximab, on cytogenetic biomarkers in peripheral lymphocytes of patients with rheumatoid arthritis (RA). A total of 40 patients with RA met the criteria to be treated with methotrexate (15 mg/week) were evaluated. Twenty patients, randomly selected, were treated with infliximab in addition to methotrexate (group I), whereas the other 20 patients continued with only methotrexate treatment (group M). Twenty healthy volunteers matched for age, gender and smoking habits served as control group (group C). At baseline, sister chromatid exchange rate was 7.20 ± 2.21 in group I, 7.40 ± 1.60 in group M and 4.97 ± 1.32 in group C (P < 0.01 vs group I and M). After 24-weeks, sister chromatid exchange rate was 7.87 ± 2.54 in group I and 7.81 ± 1.95 in group M (P = ns). High frequency cells count was 4.9 % and 4.7 % in the groups I and M, respectively, at the end of the study (P = ns). The basal chromosomal aberration frequency was 4.90 % in group I and 5.20 % in groups M; after 24-weeks, this was 5.10 % in group I and 5.10 % in groups M (P = ns). Infliximab treatment, for 24 weeks, did not increase the cytogenetic biomarkers in patients with RA. Our data show that the use of infliximab has not a genotoxic effect in patients with RA.

Genistein effects on quality of life and depression symptoms in osteopenic postmenopausal women: a 2-year randomized, double-blind, controlled study.

SUMMARY: Postmenopausal estrogen decline is implicated in several age-related physical and psychological changes in women, including decreases in perceived quality of life. The phytoestrogen genistein at a dose of 54 mg daily in osteopenic postmenopausal women after 2 years implies an improvement on quality of life and depression symptoms. INTRODUCTION: Postmenopausal estrogen decline is implicated in several age-related physical and psychological changes in women, including decreases in perceived quality of life (QoL). A number of trials with hormone therapy showed beneficial effects of the intervention on quality of life parameters. However, because of known or suspected serious side effects of conventional hormone therapy, there is a need for alternatives. METHODS: We conducted a double-blind randomized placebo-controlled trial using the isoflavone genistein, 54 mg, or placebo for 2 years. In this trial, we recruited 262 postmenopausal women aged 49 to 67 years. RESULTS: At baseline, after 1 year, and at final visit, participants filled in the Short Form of 36 questions (SF-36) and the Zung Self-rating Depression Scale (ZSDS). For the placebo group, scores on all dimensions of the SF-36 decreased after 1 and 2 years. The genistein group showed increases on all dimensions of the SF-36 at the end of the study. There were, however, statistically significant differences in changes of scores between the two intervention groups. For the ZSDS, similarly, significant differences were found between groups. CONCLUSION: In conclusion, the findings of this randomized trial showed that genistein improves quality of life (health status, life satisfaction, and depression) in osteopenic postmenopausal women.

Italian Society for Rheumatology recommendations for the management of hand osteoarthritis.

Hand osteoarthritis (OA) is a common and potentially disabling disease, with different features from hip and knee OA so that a specific therapeutic approach is required. Evidence based recommendations for the management of hand OA were developed by the European League Against Rheumatism (EULAR) in 2006. The Italian Society for Rheumatology (SIR) aimed to update, adapt to national contest and disseminate the EULAR recommendations for the management of hand OA. The multidisciplinary group of experts included specialists involved in the management of patients with hand OA. In order to maintain consistency with EULAR recommendations, a similar methodology was utilized by the Italian group. The original propositions were reformulated in terms of a search query and for every recommendation a systematic search was conducted updating EULAR recommendations' review. The propositions were translated in Italian and reformulated basing on collected evidences and expert opinion. The strength of recommendation was measured for each proposition with the EULAR ordinal and visual analogue scales. The original 11 propositions of EULAR recommendations were translated and adapted to Italian context. Further evidences were collected about non-pharmacological therapies, local treatments, intra-articular injection with SYSADOA and corticosteroids, and surgery. The SIR has developed updated recommendations for the management of hand OA adapted to the Italian healthcare system. Their implementation in clinical practice is expected to improve the management of patients with hand OA.

Safety of intra-articular hip injection of hyaluronic acid products by ultrasound guidance: an open study from ANTIAGE register.

OBJECTIVE: We developed a standardized technique for ultrasound guided intra-articular injection of the hip joint with the purpose of extending routine intra-articular injection of hyaluronans and steroids to the hip, as commonly used in the knee. In this article we report the safety of this technique in an extended series of patients. PATIENTS AND METHODS: Patients were injected supine with an anterosuperior approach under ultrasound guidance. The Us probe is applied with a target device for biopsy. RESULTS: The standardised technique was used to inject 1906 patients with 4002 injections of hyaluronan products over a four-year period. The treatment was well tolerated with few, and exclusively local, side effects. CONCLUSIONS: The administration of hyaluronans under ultrasound-guided intra-articular injection is a safe technique for treatment of rheumatic diseases of the hip.

Haemophagocytic syndrome in rheumatic patients. A systematic review.

BACKGROUND: Hemophagocytic lymphohistiocytosis (HLH), is a potentially fatal hyperinflammatory syndrome characterized fever, hepatosplenomegaly, and cytopenias. HLH can be either primary, with a genetic aetiology, or secondary, associated with malignancies, autoimmune diseases, or infections. Among rheumatic disorders, HLH occurs most frequently in systemic juvenile idiopathic arthritis. AIM: To draw attention on this severe syndrome that may often go undiagnosed in patient with rheumatic diseases. MATERIALS AND METHODS: PubMed search was performed by combining the terms (haemophagocytic, haemophagocytosis, hemophagocytosis, hemophagocytic, erythrophagocytosis, macrophage activation syndrome) and (rheumatic, rheumatologic, arthritis, lupus, Sjögren's syndrome, scleroderma, polymyositis, dermatomyositis, polymyalgia rheumatic, mixed connective tissue disease, polychondritis, sarcoidosis, polyarteritis nodosa, Henoch-Schönlein, serum sickness, wegener's granulomatosis, giant cell arteritis, temporal arteritis, Takayasu's arteritis, Behçet's syndrome, Kawasaki, Buerger's). RESULTS: 117 papers describing 421 patients were considered. HLH was described in systemic lupus erythematosus in 94 patients, in Still's disease in 37 patients, in rheumatoid arthritis in 13 patients, in systemic juvenile arthritis in 219 patients, in dermatomyositis in 7 patients, in Kawasaki disease in 25 patients, in systemic sclerosis in 5 patients, in Behcet disease in one patient, in polyarteritis nodosa in 6 patients, in ankylosing spondylitis in 2 patients, in mixed connective tissue disease in one patient, in sarcoidosis in 5 patients, in Sjögren's syndrome in 3 patients, in Wegener's granulomatosis in one patient, and in unclassifiable disorders in two patients. CONCLUSIONS: HLH occurring in the course of rheumatic diseases is an important and often underdiagnosed clinical entity, which can affect prognosis.

Far infrared emitting plaster in knee osteoarthritis: a single blinded, randomised clinical trial.

OBJECTIVE: Therapeutic approach of osteoarthritis (OA) still represents a challenge in clinical practice. The aim of the study is to assess the efficacy of far infrared (FIR) emitting plaster in the treatment of knee OA. DESIGN: This is a randomized, single-blind, placebo-controlled, parallel group with equal randomization (1:1), clinical trial. Patients affected by knee OA were randomly allocated to 1 of 2 treatment groups, either placebo plaster or far infrared emitting plaster. Primary endpoint was to assess pain improvement from baseline to 1 months posttreatment in the visual analogue score (VAS). Secondary end point was to evaluate pain score after 1 week of treatment and to compare ultrasonographic findings after 1 month of treatment. RESULTS: Each group comprised 30 (in the FIR group) and 30 (in the placebo group) completers. VAS scores of the placebo and the FIR group were significantly lower at 1 week post-treatment (95% confidence interval CI = -1.14 to 0.31; P<0.05) and at the end of the study (95% confidence interval CI = -2.57 to -0.89; P=0.01). Effect size was -0.43 after one week of treatment and -1.38 after one month of treatment. The mean decrease in VAS values was ≥ 20% in the FIR group. The number of patients from the FIR group with joint effusion was lower (40%) compared to baseline (80%), while no changes were seen among the placebo group. CONCLUSIONS: Far infrared emitting plaster could be considered an effective non-pharmacological choice for the therapeutic management of knee OA.

Treatment patterns of anti-TNF agents in Italy: an observational study.

OBJECTIVE: This study aims to provide a description of real life treatment patterns of biologic anti-TNF in 23 Italian Rheumatology centers. METHODS: This was an observational, multicenter, retrospective study. Patients >18 years of age, diagnosed with rheumatoid arthritis and treated with the first biologic anti-TNF agent between the 1st July 2002 to the 31st March 2004 were included. Total follow-up was 36 months. RESULTS: In total, 248 patients were first treated with infliximab, 259 with etanercept and 196 with adalimumab. First course of therapy with infliximab was associated with lower cumulative drug survival than the other two agents. At 36 months, 74.7% of patients on etanercept, 72.0% of those on adalimumab and 57.7% of subjects receiving infliximab were still on therapy. In total, 149 patients switched to a second anti-TNF agent. At 24 months of the second line treatment, 75%, 22%, and 54% of infliximab, etanercept and adalimumab recipients, respectively, had discontinued their second anti-TNF. CONCLUSIONS: Anti-TNF agents may be associated to a rather high incidence of discontinuation and dose adjustments over a 36-month period, with a possible effect on healthcare expense. In particular, infliximab was associated with a higher incidence of discontinuations compared with etanercept and adalimumab.

Hip viscosupplementation under ultra-sound guidance riduces NSAID consumption in symptomatic hip osteoarthritis patients in a long follow-up. Data from Italian registry.

INTRODUCTION: Non-steroidal anti-inflammatory drugs (NSAIDs) consumption is strictly related to a high gastrointestinal and cardiovascular mortality and morbidity rate. Osteoarthritis Research Society International (OARSI) recommendations in patients with symptomatic hip or knee OA stated that NSAIDs should be used at the lowest effective dose but their long-term use should be avoided if possible. OARSI guidelines for the treatment of the hip OA include the use of viscosupplementation, which aims to restore physiological and rheological features of the synovial fluid. OBJECTIVE: Aim of this multicentric, open and retrospective study is to investigate if NSAID consumption may be reduced by the use of ultrasound-guided intra-articular injection of several hyaluronic acid (HA) products in hip joint administered in patients affected by symptomatic hip OA. MATERIALS AND METHODS: Patients affected by mono or bilateral symptomatic hip OA according to American Rheumatology Association (ARA) criteria, radiological OA graded II-IV (Kellgren and Lawrence) entered the study and were administered with ultrasound-guided intra-articular injection of hyaluronic acid products. As a primary endpoint, consumption of NSAIDs was evaluated by recording the number of days a month (range 0-30) the patient had used NSAID during the previous month, reported at each visit during the 24 months follow-up period. Secondary endpoints included further analysis for subgroups of patients categorized for Lequesne index score, Kellgren-Lawrence score, pain visual analogue scale (VAS) score, ultrasound pattern, age, hyaluronic acid used. RESULTS: 2343 patients entered the study. Regarding primary endpoint, the consumption of NSAIDs was reduced of 48.2% at the third month when compared with baseline values. This sparing effect increased at 12th and 24th month with a reduction respectively of 50% and 61% in comparison to baseline values. These differences were statistically significant. CONCLUSIONS: These data point out that intraarticular hyaluronan preparations provide OA pain relief and reduce NSAIDs consumption in a large cohort of patients for a long period of follow-up. Multiple courses of viscosupplementation (vs) are required to maintain low dose of NSAID consumption over time. NSAIDs consumption is strictly related to an high gastrointestinal and cardiovascular mortality and morbidity rate, instead HA intra-articular treatment is well tolerated and is associated with a low incidence of adverse effects. For these reasons further studies evaluating cost-effectiveness and cost-utility of VS in the management of hip OA are required.

Hemostatic changes in vasculitides.

The systemic vasculitides are an heterogeneous group of rare diseases characterized by inflammation and fibrinoid necrosis of blood vessel walls. Today it is well known that the inflammatory process characterizing vasculitides activates coagulation factors, inhibits anticoagulant factors, inhibits fibrinolytic processes, increases platelet activity and production and determines endothelial dysfunction. So far the mortality in vasculitides, even if falling, remains substantially high. Patients with vasculitic syndrome are at increased risk of developing atherosclerosis and in these patients prevalence of cardiovascular disease and cardiovascular events is higher than in the general population. Vasculitides can be associated with antiphospholipid syndrome. It is important to establish a strategy of antithrombotic therapy management in vasculitic patients, but this has not yet been clearly achieved.

Osteoporotic fractures: mortality and quality of life.

Osteoporosis is a widespread disease, affecting about 75 million people, mostly postmenopausal women. It is called ''the silent disease'', since there are very few associated symptoms: anyway osteoporotic fractures are the chief clinical feature, with an enormous burden on health related quality of life and mortality. The aim of this study was to review the literature on the evaluation of mortality and health related quality of life as consequences of osteoporotic fractures. Fractures, the clinical manifestation of osteoporosis, are extremely common and are devastating both to affected patients and to society that must bear the enormous cost of fracture treatment and subsequent disability. Hip and spine fractures are linked with increased mortality, and all fractures may lead to disability and reduced quality of life. Since patients with osteoporosis usually have no symptoms before fracture, early diagnosis and treatment of the disease are of great importance to the quality of life in these patients. To reduce mortality, attention must focus on optimising health status preoperatively, preventing postoperative complications, and, when these complications develop, providing optimal specialist medical care.

[Comparation of levels of anxiety and depression in patients with autoimmune and chronic-degenerative rheumatic: preliminary data]. / Comparazione dei livelli di ansia e depressione in soggetti affetti da patologie reumatiche su base autoimmune e cronico-degenerative: dati preliminari.

UNLABELLED: Scientific research on rheumatic diseases was often focused on the link between psychological features and disease. Depression and anxiety are frequently observed with an higher incidence among rheumatic patients in comparison to general population. In autoimmune diseases, such as rheumatoid arthritis, an important role for psychiatric symptoms could be played by the alteration of cytokines levels. In the chronic-degenerative diseases, psychological factors such as stress and depression, can be involved in perception of pain. OBJECTIVE: We aimed at evaluating in a sample of 50 patients (25 with rheumatoid arthritis and 25 with osteoarthritis) levels of pain, anxiety and depression. METHODS: We evaluated two group of patients with rheumatic disease, group A (25 with Rheumatoid Arthritis, mean age = 45.1; DS =15.24) and group B (25 with osteoarthritis, mean age = 54.3; DS =14.74) by clinic examination and with the following tests, SF-MPQ, HAQ, HAM-A, HAM-D. RESULTS: We found in group A higher levels of depression and anxiety but lower levels of pain, which was more expressed in group B. CONCLUSION: Depression and anxiety were observed with an higher prevalence in patients with autoimmune disease, whereas pain was stronger in patients with osteoarthritis, a degenerative disease. We could explain this phenomenon considering the aetiopathology of the two conditions. As regard to autoimmune disorders, these symptoms may reflect the direct effect of cytokines on the central nervous system. As far as it concerns chronic-degenerative diseases, anxiety and depression are usually considered "reactive" to pain, not "constitutive".

Improving outcomes in tumour necrosis factor a treatment: comparison of the efficacy of the tumour necrosis factor a blocking agents etanercept and infliximab in patients with active rheumatoid arthritis.

AIM: The aim of this study was to evaluate the differences between infliximab and etanercept, in terms of clinical efficacy and rapidity of action. METHODS: We selected 32 patients with rheumatoid arthritis (RA) with an incomplete response to disease modifying anti-rheumatic drugs (DMARDs), and randomly assigned them to etanercept or infliximab. We evaluated the efficacy after 14, 22, 54 weeks of treatment, using the American College of Rheumatology (ACR) 20, 50 and 70 criteria, and the improvement of quality of life using the Health Assessment Question-naire (HAQ). RESULTS: After 14 weeks, the 54.4% of patients was considered ACR-responders in the etanercept group, whereas, in the infliximab group, the percentage of responders was 74.4%: infliximab gave better results for the tender joint count and for physician's global assessment. After 22 weeks, no significant difference was present. After 54 weeks, etanercept resulted more effective than infliximab for tender joint count (TJC) value, for visual analogic scale (VAS) for pain score, for global disease assessment value, with 74.4% of patients considered ACR-responders in the group treated with etanercept and 60% in the group treated with infliximab. As regards HAQ, patients in the infliximab group presented higher scores at week 14, but in weeks 22 and 54, patients in the etanercept group showed better results. Therefore, both infliximab and etanercept are efficacious in RA, but infliximab is more efficacious than etanercept in week 14. Vice versa, in week 54 etanercept is the most efficacious drug. CONCLUSIONS: Physicians have 2 weapons in their armamentarium, with the same target but distinct clinical, pharmacokinetic and pharmacodynamic properties.

[Muscle activation patterns and gait biomechanics in patients with ankylosing spondylitis]. / Pattern di attivazione muscolare e biomeccanica del passo in pazienti con spondilite anchilosante.

UNLABELLED: Patients with ankylosing spondylitis (AS) may experience a progressive spinal kyphosis, which induces a forward and downward displacement of the centre of mass (COM) of the trunk with consequent use of mechanisms to compensate for the displacement of the trunk. The analysis of patterns of movement gives an important opportunity for follow-up of patients and is an useful tool to plan a therapeutic and rehabilitative program. OBJECTIVE: The aim of our study was to contribute to the description of abnormalities of gait biomechanics in patients with AS and to individualize, if existing, a typical pattern of these patients. METHODS: Five patients with AS (3 men, 2 women) were evaluated by gait analysis. Each patient was assessed with dynamic electromyography, with survey of phases of gait cycle and 3D video-analysis of gait related to data of platform (Digivec) which allows to display real time the force vector of reaction foot-ground overlapping the screen image of patient. RESULTS: The dynamometric platform located the following problems: increasing of the medium-lateral component of the reaction force on the ground in the mild and terminal stance. The anterior-posterior reaction force is diminished in both the initial and the terminal component. The timing of activation of the tibialis anterior results prolonged while the timing of activation of the gastrocnemius medialis results delayed. CONCLUSION: The patients with AS prefer therefore an eccentric contraction of the tibial anterior in comparison to a concentric contraction of the gastrocnemius medialis, "opting" for a gait strategy that confers greater stability but limited power.

Rheumatic symptoms in patients with human immunodeficiency virus are related to levels of tumor necrosis factor-alpha but not to viral load.

Infection with human immunodeficiency virus (HIV) can lead to osteoarticular involvement, usually in the late stages. The pathogenesis of these symptoms has usually been attributed to viral load or to dysregulated cytokine production. We evaluated the presence of rheumatic symptoms and levels of tumor necrosis factor (TNF)-alpha viral load and CD4 count in 46 patients with HIV from southern Italy. The prevalence of rheumatic symptoms was 23.9%; CD4 count and viral load presented no statistically significant differences between patients with rheumatic symptoms and patients without osteoarticular involvement, whereas TNF-alpha levels were increased in HIV patients with arthralgias compared with those in patients without arthralgias (p = 0.02). Evidence that TNF-alpha is increased in patients with osteoarticular or soft tissue involvement is a clear index of the pivotal role this cytokine plays in the pathogenesis of these manifestations.

Ultrasonography in the early diagnosis of psoriasis-associated enthesopathy.

The aim of the present study was to detect entheseal abnormalities by means of ultrasonography (US) in patients with psoriasis. We evaluated 24 patients with psoriasis who underwent clinical and ultrasonographic examination of both lower limbs at the calcaneal insertions of the Achilles tendons and at the flexor and extensor tendons of all fingers of the hand. Fourteen patients with psoriatic arthritis were used as controls. US was performed using a real-time scanner (ATL SDI 3000) with a 5-12 MHz linear array transducer. Longitudinal and transverse scans of the talocrural joints, Achilles tendons and both the flexor and extensor tendons of the fingers of both hands were obtained at rest and during active and passive movements. On clinical examination no entheseal site was abnormal, but on US examination 33% of patients showed abnormalities. In particular, six psoriasis patients (25%) who were asymptomatic showed effusion around the extensor tendon of the first digit of the left hand and around the extensor tendon of the third and fourth digits of both hands; two patients (8.3%) showed a hypoechoic nodular formation of the flexor tendon sheath of the left hand. We conclude that entheseal abnormalities not detected at clinical examination were present in 33% of patients with psoriasis who underwent US examination. Therefore, we suggest the routine use of ultrasonography in the early diagnosis and in treatment and follow-up of patients with tendon enthesopathy, since these factors may have implications for therapy.
