RESUMO

BACKGROUND: Chronic pain is a key symptom in fibromyalgia (FM), and its management is still challenging for rheumatologists in daily practice. FM patients show psychological and psychiatric manifestations, going from mood and emotional disorders to depression and alexithymia that negatively impact their quality of life, limiting their daily activities. Since pharmacological strategies have a limited efficacy in FM pain, alternative or complementary non-pharmacological approaches have been introduced in the clinical management of FM. PATIENTS AND METHODS: This is a retrospective study on FM patients (n=52) treated with a novel integrated postural counseling (PC) rehabilitation program carried out by a counselor physiotherapist. The clinical impact of PC was evaluated by 1) a semi-structured interview using an ad hoc modified questionnaire McGill Illness Narrative Interview (MINI) 1 to obtain data on pain management by highlighting everyday experience of living with pain and 2) an FM impact questionnaire (FIQ) total score. RESULTS: Two main structures of narrative emplotment of FM illness were recognized: 1) the cumulative life narrative structure (46.15%) and 2) the broken life (53.85%) narrative structure. Baseline FIQ score was 77.38±7.77, and it was significantly reduced after PC to 39.12±13.27 (P<0.0001). Although well-being still requires further definition as outcome in pain management, it is important for FM patients, dealing with pain-related sensations, thoughts and feelings and limiting their daily activities. In our study, 87.5% of interviewed FM patients reported an improvement in their well-being after PC. CONCLUSION: Our data suggest that an integrated PC program positively impacts chronic pain and fatigue based on self-management strategies. PC allows FM patients to resume their own life and regenerate their own image. Finally, we propose the introduction of the evaluation of the ability to resume daily activities as the target of rehabilitation programs in FM.

RESUMO

Takayasu arteritis is a panarteritis of unknown etiology involving the aorta and its main branches, with higher prevalence in women and peak of incidence in the second and third decades of life. Up to 30% of patients have coronary lesions and aortic valve involvement. Presentation mimicking aortic dissection is quite rare. Here described is the case of a young patient, presenting with an acute coronary syndrome associated with severe aortic regurgitation, who underwent emergent surgery with the suspicion of acute aortic dissection. The diagnostic and therapeutic implications are discussed.

RESUMO

OBJECTIVES: Systemic sclerosis (SSc) is an autoimmune disease characterised by skin and systemic fibrosis culminating in organ damage. Previous genetic studies including genome-wide association studies (GWAS) have identified 12 susceptibility loci satisfying genome-wide significance. Transethnic meta-analyses have successfully expanded the list of susceptibility genes and deepened biological insights for other autoimmune diseases. METHODS: We performed transethnic meta-analysis of GWAS in the Japanese and European populations, followed by a two-staged replication study comprising a total of 4436 cases and 14 751 controls. Associations between significant single nuclear polymorphisms (SNPs) and neighbouring genes were evaluated. Enrichment analysis of H3K4Me3, a representative histone mark for active promoter was conducted with an expanded list of SSc susceptibility genes. RESULTS: We identified two significant SNP in two loci, GSDMA and PRDM1, both of which are related to immune functions and associated with other autoimmune diseases (p=1.4×10-10 and 6.6×10-10, respectively). GSDMA also showed a significant association with limited cutaneous SSc. We also replicated the associations of previously reported loci including a non-GWAS locus, TNFAIP3. PRDM1 encodes BLIMP1, a transcription factor regulating T-cell proliferation and plasma cell differentiation. The top SNP in GSDMA was a missense variant and correlated with gene expression of neighbouring genes, and this could explain the association in this locus. We found different human leukocyte antigen (HLA) association patterns between the two populations. Enrichment analysis suggested the importance of CD4-naïve primary T cell. CONCLUSIONS: GSDMA and PRDM1 are associated with SSc. These findings provide enhanced insight into the genetic and biological basis of SSc.

RESUMO

OBJECTIVE: To analyze the characteristics of anti-RNA polymerase III antibodies (anti-RNAP3)- positive patients with systemic sclerosis (SSc) in the European League Against Rheumatism Scleroderma Trials and Research group (EUSTAR) registry with a focus on the risk of cancer and the characteristics of malignancies, and the aim to provide guidelines about potential cancer screening in these patients. METHODS: (1) Analysis of the EUSTAR database: 4986 patients with information on their anti-RNAP3 status were included. (2) Case-control study: additional retrospective data, including malignancy history, were queried in 13 participating EUSTAR centers; 158 anti-RNAP3+ cases were compared with 199 local anti-RNAP3- controls, matched for sex, cutaneous subset, disease duration, and age at SSc onset. (3) A Delphi exercise was performed by 82 experts to reach consensus for cancer screening in anti-RNAP3+ patients. RESULTS: In the EUSTAR registry, anti-RNAP3 were associated in multivariable analysis with renal crisis and diffuse cutaneous involvement. In the case-control study, anti-RNAP3 were associated with gastric antral vascular ectasia, rapid progression of skin involvement, and malignancies concomitant to SSc onset (OR 7.38, 95% CI 1.61-33.8). When compared with other anti-RNAP3+ patients, those with concomitant malignancies had older age (p < 0.001) and more frequent diffuse cutaneous involvement (p = 0.008). The Delphi exercise highlighted the need for malignancy screening at the time of diagnosis for anti-RNAP3+ patients and tight followup in the following years. CONCLUSION: Anti-RNAP3+ patients with SSc have a high risk of concomitant malignancy. These results have implications for clinical practice and suggest regular screening for cancer in anti-RNAP3+ patients.

RESUMO

OBJECTIVE: To estimate the prevalence, determine the subgroups at risk, and the outcomes of patients with systemic sclerosis (SSc) and gastric antral vascular ectasia (GAVE). METHODS: We queried the European League Against Rheumatism Scleroderma Trials and Research (EUSTAR) network for the recruitment of patients with SSc-GAVE. Each case was matched for cutaneous subset and disease duration with 2 controls with SSc recruited from the same center, evaluated at the time the index case made the diagnosis of GAVE. SSc characteristics were recorded at the time GAVE occurred and the last observation was collected to define the outcomes. RESULTS: Forty-nine patients with SSc and GAVE were included (24 with diffuse cutaneous SSc) and compared to 93 controls with SSc. The prevalence of GAVE was estimated at about 1% of patients with SSc. By multivariate analysis, patients with SSc-GAVE more frequently exhibited a diminished (< 75%) DLCO value (OR 12.8; 95% CI 1.9-82.8) despite less frequent pulmonary fibrosis (OR 0.2; 95% CI 0.1-0.6). GAVE was also associated with the presence of anti-RNA-polymerase III antibodies (OR 4.6; 95% CI 1.2-21.1). SSc-GAVE was associated with anemia (82%) requiring blood transfusion (45%). Therapeutic endoscopic procedures were performed in 45% of patients with GAVE. After a median followup of 30 months (range 1-113 months), survival was similar in patients with SSc-GAVE compared to controls, but a higher number of scleroderma renal crisis cases occurred (12% vs 2%; p = 0.01). CONCLUSION: GAVE is rare and associated with a vascular phenotype, including anti-RNA-polymerase III antibodies, and a high risk of renal crisis. Anemia, usually requiring blood transfusions, is a common complication.

RESUMO

The aims of this study were to evaluate body composition in systemic sclerosis (SSc) and to assess its association with the traditional risk factors for atherosclerosis and parameters of lung function. Eighty-six patients affected by SSc (13 men and 73 women, mean age 58.5 years, mean disease duration 10.7 years, 31 with diffuse form and 55 with limited pattern) underwent evaluation of body composition using a dual-energy X-ray (DXA) fan beam densitometer (GE Lunar iDXA) in order to assess total and regional body fat mass and fat-free mass. Clinical features, pulmonary function parameters, and the concomitant presence of the traditional cardiovascular risk factors were recorded. Android fat resulted to be higher in SSc patients with coexistence of hypercholesterolemia (P = 0.021), hypertension (P = 0.028), and overweight/obesity (P < 0.001) and positively correlated with body mass index (P < 0.001). Forced vital capacity (FVC) was inversely correlated with android fat (P = 0.034) and with the android fat/gynoid fat ratio (P = 0.013) and positively correlated with android lean (P = 0.041); the correlations were improved when FVC data were adjusted for sex, age, disease duration, and smoking habits (P = 0.010 for android fat, P = 0.010 for android fat/gynoid fat ratio, P = 0.011 for android lean). In this study, we showed that visceral abdominal fat, measured by DXA, is correlated with the main cardiovascular risk factors and lung volumes in SSc patients. Longitudinal studies are needed to evaluate if decrease of abdominal fat would improve lung function.

RESUMO

To evaluate in a cohort of 100 consecutive patients affected by primary Sjogren's syndrome (pSS) the incidence of Hashimoto thyroiditis (HT) and to compare the clinical features and the laboratory parameters of patients affected by pSS with and without concomitant HT. In 100 consecutive patients affected by pSS, the occurrence of other autoimmune diseases was recorded and a full examination of thyroid function obtained. HT was associated with pSS in 27 cases. The comparison between pSS cases with and without HT showed that only patients with isolated pSS had low C4 level [p = 0.032, OR (IC 95 %) 230 (13.13-4,046)]. In addition, only patients affected by pSS without HT had evidence of cryoglobulins, cutaneous vasculitis with palpable purpura, peripheral neuropathy, and development of lymphoma, although all these manifestations were observed in a 4.1-8.2 % of the cases, without reaching statistical significance. The association of HT in patients suffering from pSS defines a subset of patients with milder disease and normal C4 levels.

RESUMO

OBJECTIVE: Systemic lupus erythematosus (SLE) and systemic sclerosis (SSc) share some pathophysiologic bases as evidenced by individual and familial polyautoimmunity and common susceptibility genetic factors. With regard to the latter, there has been a recent shift from the "common variant" to the "rare variant" paradigm, since rare variants of TNFAIP3 and TREX1 with large effect sizes have recently been discovered in SLE. The present study was undertaken to investigate whether rare variants of TNFAIP3 and TREX1 are also associated with SSc. METHODS: TREX1 single-nucleotide polymorphisms (SNPs) rs3135946, rs7626978, rs3135943, and rs11797 and TNFAIP3 SNPs rs9494883, rs72063345, rs5029939, rs2230926, rs117480515, and rs7749323 were genotyped in a discovery set (985 SSc patients and 1,011 controls), and replication analysis of the most relevant results was performed in a second set (622 SSc patients and 493 controls). RESULTS: No association between TREX1 variants and SSc was observed. For TNFAIP3, we first demonstrated that a low-frequency variant, rs117480515, tagged the recently identified TT>A SLE dinucleotide. In the discovery sample, we observed that all tested TNFAIP3 variants were in linkage disequilibrium and were associated with SSc and various SSc subsets, including the polyautoimmune phenotype. We subsequently genotyped rs117480515 in the replication sample and found it to be associated solely with the SSc polyautoimmune subset (odds ratio 3.51 [95% confidence interval 2.28-5.41], P = 8.58 × 10(-9) ) in the combined populations. Genotype-messenger RNA (mRNA) expression correlation analysis revealed that the TNFAIP3 rs117480515 risk allele was associated with decreased mRNA expression. CONCLUSION: The present findings establish the TNFAIP3 locus as a susceptibility factor for the subset of SSc with a polyautoimmune phenotype. Our results support the implication of rare/low-frequency functional variants and the critical role of A20 in autoimmunity.

RESUMO

OBJECTIVES: To obtain experiences and expert opinion on treatment of SSc patients with TNF-α antagonists. METHODS: An investigation was carried out among the EUSTAR centres into their expertise on use of TNF-α antagonists. Assessment forms on the frequency of TNF-α inhibitor use were distributed to EULAR Scleroderma Trials and Research Group (EUSTAR) centres. Afterwards, a three round Delphi exercise was performed to obtain expert consensus on the use of TNF-α inhibitors in SSc. RESULTS: Seventy-nine centres returned information on use of TNF-α antagonists in SSc patients. A total of 65 patients were treated with TNF-α inhibitors in 14 different centres. Forty-eight of the 65 patients treated with TNF-α inhibitors improved. Improvement was mainly seen in patients with arthritis, whereas the effects on fibrosis varied. In the first round of the subsequent Delphi approach, 71 out of 79 experts stated that they would use TNF-α antagonists in SSc. Arthritis was suggested as an indication for TNF-α antagonists by 75% of the experts. However, after the third stage of the Delphi exercise, the acceptance for the off-label use of TNF-α antagonists decreased and 59% recommended that TNF-α antagonists should not be used or only used in clinical trials in SSc patients, while 38% of the experts suggested the use of TNF-α antagonists for arthritis associated with SSc. CONCLUSIONS: Most of the experts do not recommend the routine use of TNF-α antagonists in systemic sclerosis. Arthritis might be a potential indication in SSc, although controlled clinical trials with TNF-α antagonists are needed before general recommendations can be given.

RESUMO

OBJECTIVE: Barrett's oesophagus (BE) is the major risk factor for oesophageal adenocarcinoma (EAC). SSc is associated with an increased risk of BE related to chronic reflux. The aim of this study is to determine the outcomes of BE and estimate the EAC risk in SSc patients over a 3-year prospective study. METHODS: SSc patients were recruited through EUSTAR network centres. Inclusion criterion was a recent histological finding of BE. The patients were then prospectively followed and, as recommended, a second oesophageal endoscopy was performed according to the presence of BE-related dysplasia at baseline. RESULTS: A total of 50 SSc patients with BE (40 without and 10 with dysplasia) were included and 46 completed the follow-up (138 patient-years). During the 3-year follow-up, 4 of the 46 BE patients (3% per year) were diagnosed with high-grade dysplasia/EAC, of which one developed cardial EAC. EAC incidence in the BE subgroup with dysplasia increased to 4% per year compared with the absence of EAC cases in the BE subgroup without dysplasia at baseline. CONCLUSION: Our results, in accordance with previous published data suggesting an increased risk of EAC or cardial adenocarcinoma in SSc, highlight the need for accurate follow-up of BE SSc patients at risk of developing adenocarcinoma.

RESUMO

OBJECTIVES: To determine the causes and predictors of mortality in systemic sclerosis (SSc). METHODS: Patients with SSc (n=5860) fulfilling the American College of Rheumatology criteria and prospectively followed in the EULAR Scleroderma Trials and Research (EUSTAR) cohort were analysed. EUSTAR centres completed a structured questionnaire on cause of death and comorbidities. Kaplan-Meier and Cox proportional hazards models were used to analyse survival in SSc subgroups and to identify predictors of mortality. RESULTS: Questionnaires were obtained on 234 of 284 fatalities. 55% of deaths were attributed directly to SSc and 41% to non-SSc causes; in 4% the cause of death was not assigned. Of the SSc-related deaths, 35% were attributed to pulmonary fibrosis, 26% to pulmonary arterial hypertension (PAH) and 26% to cardiac causes (mainly heart failure and arrhythmias). Among the non-SSc-related causes, infections (33%) and malignancies (31%) were followed by cardiovascular causes (29%). Of the non-SSc-related fatalities, 25% died of causes in which SSc-related complications may have participated (pneumonia, sepsis and gastrointestinal haemorrhage). Independent risk factors for mortality and their HR were: proteinuria (HR 3.34), the presence of PAH based on echocardiography (HR 2.02), pulmonary restriction (forced vital capacity below 80% of normal, HR 1.64), dyspnoea above New York Heart Association class II (HR 1.61), diffusing capacity of the lung (HR 1.20 per 10% decrease), patient age at onset of Raynaud's phenomenon (HR 1.30 per 10 years) and the modified Rodnan skin score (HR 1.20 per 10 score points). CONCLUSION: Disease-related causes, in particular pulmonary fibrosis, PAH and cardiac causes, accounted for the majority of deaths in SSc.

RESUMO

Anti-TNFalpha blockers are extensively used in the management of chronic inflammatory disorders. Their administration may be associated with the generation of autoantibodies; this review focuses on the autoimmune phenomena linked to anti-TNFalpha inhibition, on the hypothesized pathogenetic mechanisms and on the clinical implications. While the development of antinuclear and, less frequently, of anti-DNA antibodies is a common finding, the onset of autoimmune diseases during anti-TNFalpha blocker treatment is a rare event, which needs to be promptly recognized in order to plan the appropriate management. Moreover the specific autoantibodies associated with rheumatoid arthritis are considered before and after biotherapy. Similarities and differences among infliximab, etanercept and adalimumab concerning induced autoimmune phenomena are underlined.

RESUMO

A single series of patients affected by systemic sclerosis (SSc) and cyclically treated with iloprost was reviewed in order to evaluate the incidence of digital ulcers (DUs) and to compare the characteristics between the patients with and without this painful and disabling vascular complication. The record charts of 85 SSc patients were revised. Ischemic DUs and scleroderma contracture ulcers were separately considered. Twenty-nine subjects developed ischemic DUs during the course of the disease; whereas, scleroderma contracture ulcers occurred in six subjects. Ischemic DUs were associated with younger age at scleroderma onset, a longer disease duration, a longer time delay from scleroderma diagnosis to iloprost therapy, a bigger skin involvement, the presence of joint contractures, a videocapillaroscopic late pattern, a history of smoking, and of corticosteroids therapy. After the exclusion of four subjects with concomitant peripheral arterial disease, a forward-stepwise logistic regression analysis showed that only four variables, i.e., age at scleroderma onset, delay in beginning iloprost therapy, history of smoking, and presence of joint contractures remained significantly associated with ischemic DUs. In a score reflecting the sum of these four risk factors, the prevalence of ischemic DUs increased progressively from the lowest to the highest value of the score. The predictivity of this model was evaluated by the receiver-operating characteristics curve, with an estimated area under the curve of 0.836 with 95% confidence interval from 0.736 to 0.937. All the patients with scleroderma contracture ulcers were characterized by both diffuse pattern of disease and positivity for anti-Scl70 antibody. In this retrospective study, scleroderma patients with ischemic DUs are characterized by early disease onset, delay in beginning iloprost therapy, smoking habit, and presence of joint contraction. A score reflecting the sum of these factors may be useful to predict the risk of developing ischemic DUs.

RESUMO

We report on the first association of celiac disease, polyarteritis nodosa and HBV infection in a patient who developed a neuropathy. On admission his general and neurological conditions were severely compromised. Haematological test revealed HBV infection and high levels of antibodies to tissue transglutaminase, endomysium, gliadin. EMG showed sensory-motor asymmetric axonal neuropathy. A sural nerve biopsy revealed fibre loss, axonal degeneration with asymmetrical distribution and fascicular ischaemia. A duodenal biopsy was consistent with celiac disease. The patient was treated with immunosuppressive and antiviral therapy, and gluten-free diet with good result. Celiac disease can be related to a higher risk of autoimmune disorders and may have contributed to the development of multineuropathy in this patient.

RESUMO

This paper describes a 48-year-old woman admitted to surgical department with mid-epigastric pain. Ultrasonography of the abdomen and magnetic resonance imaging revealed an ipoechoic mass in the head of pancreas suggestive for malignant tumor. She underwent pancreaticoduodenectomy; histologic examination showed a granulomatous inflammation with necrosis and destruction of the wall of small-medium size blood vessels very suggestive for Wegener's granulomatosis (WG). No other visceral involvement was found; test for antineutrophil cytoplasmic antibodies was negative. Initial and symptomatic involvement of pancreas was reported in very few cases of WG.

RESUMO

OBJECTIVE: To characterize the clinical and immunologic patterns of expression, response to therapy, and outcome of patients with Sjögren's syndrome (SS) and associated hepatitis C virus (HCV) infection who developed B cell lymphoma. METHODS: Various international reference centers constituted a multicenter study group with the purpose of creating a registry of patients with SS-HCV who developed B cell lymphoma. A protocol form was used to record the main characteristics of SS, chronic HCV infection, and B cell lymphoma. RESULTS: Twenty-five patients with SS-HCV with B cell lymphoma were included in the registry. There were 22 (88%) women and 3 (12%) men (mean age 55, 58, and 61 years at SS, HCV infection, and lymphoma diagnosis, respectively). The main extraglandular SS manifestations were cutaneous vasculitis in 15 (60%) patients and peripheral neuropathy in 12 (48%); the main immunologic features were positive rheumatoid factor (RF) in 24 (96%) and type II cryoglobulins in 20 (80%). The main histologic subtypes were mucosa-associated lymphoid tissue (MALT) lymphoma in 11 (44%) patients, diffuse large B cell lymphoma in 6 (24%), and follicular center cell lymphoma in 6 (24%). Fifteen (60%) patients had an extranodal primary location, most frequently in the parotid gland (5 patients), liver (4 patients), and stomach (4 patients). Twelve (52%) of 23 patients died after a median followup from the time of lymphoma diagnosis of 4 years, with lymphoma progression being the most frequent cause of death. Survival differed significantly between the main types of B cell lymphoma. CONCLUSION: Patients with SS-HCV and B cell lymphoma are clinically characterized by a high frequency of parotid enlargement and vasculitis, an immunologic pattern overwhelmingly dominated by the presence of RF and mixed type II cryoglobulins, a predominance of MALT lymphomas, and an elevated frequency of primary extranodal involvement in organs in which HCV replicates (exocrine glands, liver, and stomach).

RESUMO

We present the case of a 75-year-old woman with suspected giant cell arteritis. In the diagnostic procedure, we used B-flow ultrasound, a non-Doppler technology for blood flow imaging. The advantages of this technique and its possible role in the diagnosis of giant cell arteritis are discussed.
