Healthcare utilization and unmet needs of patients with antisynthetase syndrome: An international patient survey.

Antisynthease syndrome (ASSD) is a rare, complex and understudied autoimmune disease. Internet-based studies can overcome barriers of traditional on-site research and are therefore very appealing for rare diseases. The aim of this study was to investigate patient-reported symptoms, diagnostic delay, symptoms, medical care, health status, working status, disease knowledge and willingness to participate in research of ASSD patients by conducting an international web-based survey. The multilingual questionnaire was created by an international group of rheumatologists and patients and distributed online. 236 participants from 22 countries completed the survey. 184/236 (78.0%) were female, mean age (SD) was 49.6 years (11.3) and most common antisynthetase antibody was Jo-1 (169/236, 71.6%). 79/236 (33.5%) reported to work full-time. Median diagnostic delay was one year. The most common symptom at disease onset was fatigue 159/236 (67.4%), followed by myalgia 130/236 (55.1%). The complete triad of myositis, arthritis and lung involvement verified by a clinician was present in 42/236 (17.8%) at disease onset and in 88/236 (37.3%) during the disease course. 36/236 (15.3%) reported to have been diagnosed with fibromyalgia and 40/236 (16.3%) with depression. The most reported immunosuppressive treatments were oral corticosteroids 179/236 (75.9%), followed by rituximab 85/236 (36.0%). 73/236 (30.9%) had received physiotherapy treatment. 71/236 (30.1%) reported to know useful online information sources related to ASSD. 223/236 (94.5%) were willing to share health data for research purposes once a year. Our results reiterate that internet-based research is invaluable for cooperating with patients to foster knowledge in rare diseases.

The Italian Society of Rheumatology clinical practice guidelines for the diagnosis and management of gout.

Gout is a chronic disease with an increased risk of premature death related to comorbidities. Treatment of gout has proved suboptimal and clinical practice guidelines (CPGs) are expected to have a key role in achieving improvement. Since new evidence has become available, the Italian Society for Rheumatology (SIR) has been prompted to update the 2013 recommendations on the diagnosis and management of gout. The framework of the Guidelines International Network Adaptation Working Group was adopted to identify, appraise (AGREE II), synthesize, and customize the existing gout CPGs to the needs of the Italian healthcare context. The task force consisting of rheumatologists from the SIR Epidemiology Unit and a committee with experience on gout identified key health questions to guide a systematic literature review. The target audience includes physicians and health professionals who manage gout in practice, and the target population includes adult patients suspected or diagnosed as having gout. These recommendations were finally rated by an external multi-disciplinary commission. From a systematic search in databases (Medline, Embase) and grey literature, 8 CPGs were selected and appraised by two independent raters. Combining evidence and statements from these CPGs and clinical expertise, 14 recommendations were developed and graded according to the level of evidence. The statements and potential impact on clinical practice were discussed and assessed. These revised recommendations are intended to provide guidance for the diagnosis and the treatment of gout and to disseminate the best evidence-based healthcare for this disease.

Nailfold videocapillaroscopy in antisynthetase syndrome.

A 57-year-old woman with a diagnosis of antisynthetase syndrome (ASSD) underwent a nailfold videocapillaroscopy (NVC) showing a scleroderma pattern. Alterations in capillary morphology have been reported in adults with inflammatory myositis (IM) but only recently have the differences in NVC findings between these two diseases been established. ASSD is currently classified as a subset of IM, for which reason only a few studies in literature evaluate its specific hallmarks, showing nonspecific features of NVC in patients with polymyositis and dermatomyositis (DM) and antisynthetase antibodies. To our knowledge, this is the first description of ASSD capillaroscopy features, and the first report of NVC in ASSD with evidence of scleroderma pattern. Further studies are needed to define clearly frequency, typical features, and possible correlation with clinical and serological data of NVC changes in ASSD, differences between microangiopathy in ASSD and systemic sclerosis or DM.

Combined interventional sialendoscopy and intraductal steroid therapy for recurrent sialadenitis in Sjögren's syndrome: Results of a pilot monocentric trial.

OBJECTIVES: To evaluate the effectiveness of interventional sialendoscopy alone or combined with outpatient intraductal steroid irrigations in patients with sialadenitis due to Sjögren's syndrome (SS). DESIGN: A pilot therapeutic study. SETTING: ENT Clinics, Universities of Milan and Pavia. STUDY POPULATION: We included 22 patients with SS of whom 12 underwent interventional sialendoscopy followed by intraductal steroid irrigations (group A), and 10 interventional sialendoscopy alone (group B). OUTCOMES MEASURES: The following outcome measures were considered and recorded before and after the therapeutic intervention: (i) number of episodes of glandular swelling, (ii) cumulative prevalence of patients with glandular swelling assessed by the specific domain, the EULAR SS Disease Activity Index (ESSDAI), (iii) severity of pain by means of a 0-10 pain visual analogue scale (VAS), (iv) severity of xerostomia and other disease symptoms assessed by the EULAR SS Patient Reported Index (ESSPRI) and the Xerostomia Inventory questionnaire. RESULTS: The postoperative reduction in the mean number of episodes of glandular swelling was 87% (95% CI: 77-93) and 75% (95% CI: 47%-88%) in the groups A and B, respectively. The percentage of patients with glandular swelling decreased from 41.7% to 0.0% in the group A and from 30.0% to 0.0% in the group B, respectively. Most of the patients experienced a subjective clinical improvement documented by the statistically significant reductions in the postoperative mean pain VAS (group A P<.001; group B P=.004), Xerostomia Inventory (P<.001 and P=.003) and ESSPRI scores (P<.001 and P=.008). Interventional sialendoscopy followed by outpatient intraductal steroid irrigations was more effective than interventional sialendoscopy alone, when pain VAS, Xerostomia Inventory and ESSPRI scores before and after treatment were analysed together using the multivariate Hotelling T2 test (P=.0173). CONCLUSIONS: This pilot study confirms that interventional sialendoscopy with steroid duct irrigation significantly reduces the number of painful episodes of sialadenitis and improves the subjective sensation of oral dryness and other disease symptoms in patients with SS. The study results also suggest that the improvement is greater when interventional sialendoscopy is combined with a cycle of outpatient steroid ductal irrigations. Larger controlled randomised studies are certainly needed to confirm these preliminary data.

The emerging role of biotechnological drugs in the treatment of gout.

One of the most important therapeutic advances obtained in the field of rheumatology is the availability of the so-called bio(techno)logical drugs, which have deeply changed treatment perspectives in diseases such as rheumatoid arthritis and ankylosing spondylitis. According to the steadily increasing attention on gout, due to well-established prognostic and epidemiology implications, in the last 5 years, the same change of perspective has been observed also for this disease. In fact, several bio(techno)logical agents have been investigated both for the management of the articular gout symptoms, targeting mainly interleukin-1 ß , as well as urate-lowering therapies such as recombinant uricases. Among the IL-1 ß inhibitors, the majority of studies involve drugs such as anakinra, canakinumab, and rilonacept, but other compounds are under development. Moreover, other potential targets have been suggested, as, for example, the TNF alpha and IL-6, even if data obtained are less robust than those of IL-1 ß inhibitors. Regarding urate-lowering therapies, the recombinant uricases pegloticase and rasburicase clearly showed their effectiveness in gout patients. Also in this case, new compounds are under development. The aim of this review is to focus on the various aspects of different bio(techno)logical drugs in gouty patients.

Overuse of prescription and OTC non-steroidal anti-inflammatory drugs in patients with rheumatoid arthritis and osteoarthritis.

Non-steroidal anti-inflammatory drugs (NSAIDs) have been demonstrated to have significant cardiovascular and gastrointestinal toxicity; high dose of intake and concomitant use of multiple compounds or corticosteroids are factors that increase the risk of NSAID toxicity. In this paper we described our experience on NSAIDs misuse (both prescribing and OTC formulations), particularly relevant in the setting of rheumatoid arthritis (39.5 percent of patients) and osteoarthritis (47 percent of patients). We also evaluated causes underlying NSAIDs misuse (e.g. not satisfactory pain control, other painful conditions, etc).

Frequency of Th1, Th2 and Th17 producing T lymphocytes in bronchoalveolar lavage of patients with systemic sclerosis.

OBJECTIVE: The pathophysiology of the lung fibrotic process in systemic sclerosis (SSc) is not fully elucidated. Since this pattern represents the leading cause of death in SSc, the knowledge of its actual pathophysiology is basic to prevent and stage pulmonary damage. In this study, we aimed to further investigate the relationship between the functional profiles of bronchoalveolar lavage (BAL) T cells and the pulmonary manifestation of the disease. METHODS: With this aim, we assessed the frequency of Th1, Th2 and Th17 producing T-lymphocytes and their effector cytokines in BAL of SSc patients without signs or symptoms of lung interstitial involvement (SScFib-) and with interstitial lung fibrosis (SScFib+). We also study as control groups: patients with usual interstitial pneumonia (UIP), patients with sarcoidosis and 9 healthy controls (NHCs). RESULTS: SScFib- showed an increase in BAL Th1/Th2 balance compared to NHCs, which was even higher than that observed in sarcoidosis. SScFib+ showed a shift towards a lower Th1/Th2 ratio as compared to SScFib-. The frequency of Th17 BAL T cells did not change among study groups. CONCLUSION: Our data confirm the Th1/Th2 imbalance hypothesis on the pathogenesis of interstitial fibrosis in SSc patients, and suggest a possible utility in the assessment of BAL Th1/Th2 ratio.

Analysis of bronchoalveolar lavage fluid proteome from systemic sclerosis patients with or without functional, clinical and radiological signs of lung fibrosis.

Lung fibrosis is a major cause of mortality and morbidity in systemic sclerosis (SSc). However, its pathogenesis still needs to be elucidated. We examined whether the alteration of certain proteins in bronchoalveolar lavage fluid (BALF) might have a protective or a causative role in the lung fibrogenesis process. For this purpose we compared the BALF protein profile obtained from nine SSc patients with lung fibrosis (SScFib+) with that obtained from six SSc patients without pulmonary fibrosis (SScFib-) by two-dimensional gel electrophoresis (2-DE). Only spots and spot-trains that were consistently expressed in a different way in the two study groups were taken into consideration. In total, 47 spots and spot-trains, corresponding to 30 previously identified proteins in human BALF, showed no significant variation between SScFib+ patients and SScFib- patients, whereas 24 spots showed a reproducible significant variation in the two study groups. These latter spots corresponded to 11 proteins or protein fragments, including serum albumin fragments (13 spots), 5 previously recognized proteins (7 spots), and 4 proteins (3 spots) that had not been previously described in human BALF maps, namely calumenin, cytohesin-2, cystatin SN, and mitochondrial DNA topoisomerase 1 (mtDNA TOP1). Mass analysis did not determine one protein-spot. The two study groups revealed a significant difference in BALF protein composition. Whereas levels of glutathione S-transferase P (GSTP), Cu-Zn superoxide dismutase (SOD) and cystatin SN were downregulated in SScFib+ patients compared with SScFib- patients, we observed a significant upregulation of alpha1-acid glycoprotein, haptoglobin-alpha chain, calgranulin (Cal) B, cytohesin-2, calumenin, and mtDNA TOP1 in SScFib+ patients. Some of these proteins (GSTP, Cu-Zn SOD, and cystatin SN) seem to be involved in mechanisms that protect lungs against injury or inflammation, whereas others (Cal B, cytohesin-2, and calumenin) seem to be involved in mechanisms that drive lung fibrogenesis. Even if the 2-DE analysis of BALF did not provide an exhaustive identification of all BALF proteins, especially those of low molecular mass, it allows the identification of proteins that might have a role in lung fibrogenesis. Further longitudinal studies on larger cohorts of patients will be necessary to assess their usefulness as predictive markers of disease.

Diagnostic value of procalcitonin measurement in febrile patients with systemic autoimmune diseases.

OBJECTIVE: To determine the usefulness of plasma procalcitonin (PCT) measurement to suspect infectious etiology in febrile patients with systemic autoimmune disease. METHODS: PCT, C-Reactive protein (CRP), erythrocyte sedimentation rate (ESR) and white blood cell count (WBC) were measured in 44 consecutive inpatients with a diagnosis of systemic autoimmune disease and fever >38 masculine C. After careful microbiologic screening no obvious infection was demonstrated in 24 patients (Group A) while an infectious bacterial complication was diagnosed in 20 cases (Group B). RESULTS: Median PCT levels were significantly higher in the group B (1.11 vs 0.24 ng/ml; p = 0.0007), whereas the differences for CRP, WBC and ESR did not reach statistical significance. PCT also exhibited a good sensitivity and specificity (75%) in differentiating patients with infection from those with disease flare. With respect to positive and negative predictive values (71.4% and 78.2%), PCT markedly exceeded the other variables. By analyzing PCT values by disease we identified a false positive subgroup of patients suffering from adult onset Still's disease (AOSD), showing markedly elevated PCT levels in absence of infection. By excluding these patients, PCT showed a very good sensitivity and specificity (73.6% and 89.4%) and the area under receiver operating characteristics (ROC) curve rose from 0.801 to 0.904. CONCLUSION: Our data indicate that elevated PCT concentrations offer good sensitivity and specificity for the diagnosis of systemic bacterial infection in febrile patients with systemic autoimmune diseases. However, in fever associated with AOSD PCT may be elevated even in the absence of infectious complication.

Serum cytokines and steroidal hormones in polymyalgia rheumatica and elderly-onset rheumatoid arthritis.

BACKGROUND: Polymyalgia rheumatica (PMR) may create some difficulties in the differential diagnosis of elderly-onset rheumatoid arthritis (EORA) and of EORA with PMR-like onset (EORA/PMR). AIM: To investigate possible differences between three groups of patients, with regard to serum levels of inflammatory cytokines and steroidal hormones at baseline and after 1 month of treatment with glucocorticoids (prednisone 7.5-12.5 mg/day). PATIENTS AND METHODS: 14 patients with PMR, 15 with EORA and 14 with EORA/PMR, as well as 15 healthy, matched controls were analysed. Tumour necrosis factor alpha (TNFalpha), interleukin (IL)6, IL1 receptor antagonist (IL1Ra), cortisol, dehydroepiandrosterone sulphate (DHEAS) and 17-hydroxy-progesterone (PRG) were evaluated. RESULTS: Serum levels of both TNFalpha and IL6 were significantly higher in all three groups of patients than in controls (p<0.01). Serum IL6 levels were significantly higher in patients with both PMR and EORA/PMR than in patients with EORA (p<0.05). IL1Ra serum levels were significantly higher in patients with EORA than in controls (p<0.001) and in patients with PMR and EORA/PMR (p<0.05). DHEAS was significantly lower in patients with EORA/PMR than in those with EORA (p<0.05). PRG was significantly higher in all patient groups (p<0.05). After glucocorticoid treatment, serum TNFalpha and IL6 levels significantly decreased in all patient groups; IL1Ra significantly increased in patients with PMR and in those with EORA/PMR; cortisol, DHEAS, and PRG significantly decreased in patients with PMR and in those with EORA/PMR (p<0.05). CONCLUSIONS: Different cytokine and steroidal hormone patterns suggest that patients with PMR and those with EORA/PMR seem to be have a more intensive inflammatory reaction and are more efficient responders to glucocorticoid treatment than patients with EORA.

[Early electroretinografic changes in elderly RA patients treated with hydroxychloroquine]. / Variazioni elettroretinografiche precoci nei pazienti anziani con artrite reumatoide trattata con idrossiclorochina.

OBJECTIVE: To evaluate the effectiveness of fundoscopy, electrooculography, electroretinogram and visually evoked potentials in early detection of hydroxychloroquine retinal toxicity in RA patients and to evaluate the influence of patients' age, drug dosage, concomitant therapy (prednisone and methotrexate) and serum creatinine levels in the development of this side effect. METHODS: From september to december 1999, we have enrolled 32 RA patients (13 males, 19 females) starting hydroxychloroquine treatment. The patients underwent regular ophthalmological examination (fundoscopy, electro-oculography, electroretinogram and visually evoked potentials) every 4 months. Disease activity was evaluated every two months by clinical and routine serological examination. RESULTS: No patients developed retinopathy during 1 year's follow-up; fundoscopy, electrooculography, and visually evoked potentials did not vary from the baseline. On the other hand, electroretinogram showed early alterations of scotopic and photopic response; moreover a significant statistical correlation between patients' age (more than 65 years) and b1 photopic wave increase (p < 0,05) was observed. No correlation was found between the development of electro-retinographic alterations and hydroxychloroquine dosage, concomitant therapy and serum creatinine levels CONCLUSION: Our data show the inefficacy of fundoscopy, electrooculography and visually evoked potentials in early detection of hydroxychloroquine retinopathy. On the other hand electroretinogram allows early detection of retinal alterations during hydroxychloroquine treatment, in patients older than 65 years.

Infliximab in the treatment of adult Still's disease refractory to conventional therapy.

In this study we evaluated the efficacy of Infliximab in the treatment of adult Still's disease (ASD) refractory to conventional therapy. Three patients with chronic and active ASD unresponsive to corticosteroids and methotrexate were given intravenous Infliximab infusions at a dosage of 3 mg/kg at weeks 0, 2, 6 and then once every 8 weeks. Methotrexate was maintained in all cases at a dosage of 15 mg/week, whereas the prednisone dose was modified according to disease activity. The follow-up lasted 50 weeks and disease activity improved in all cases during Infliximab therapy. Two patients presented arthralgias and sore throat at 20 and 28 weeks, that was rapidly controlled by Infliximab reinfusion every 4 weeks. One patient relapsed at 18 weeks and dropped out at 22 weeks due to an urticarioid rash after the beginning of the fifth infusion. Infliximab may be effective in the treatment of relapse of ASD refractory to conventional therapy and requiring continuous high dose corticosteroid medication. Further studies are needed to evaluate the long-term safety, efficacy and the optimal schedule of infusion.
