VEXAS syndrome diagnosis starting from ultrasound findings: a case report.

VEXAS syndrome is a recently described condition characterized by systemic inflammation, predisposition to hematologic malignancy and a high rate of venous thrombosis. Here we report the case of an elderly male with erythema nodosumlike lesions, ankle arthralgia, and general symptoms. B-mode and Doppler ultrasound of the subcutis diagnosed superficial thrombophlebitis of the lower limbs, which turned out to be the manifestation of a paucisymptomatic VEXAS syndrome. VEXAS should be considered in any patient who presents with unexplained superficial thrombophlebitis, macrocytic anemia and unexplained systemic inflammation.

Enhanced Innate and Acquired Immune Responses in Systemic Sclerosis Primary Peripheral Blood Mononuclear Cells (PBMCs).

Chronic immune activation in systemic sclerosis is supported by the production of a plethora of cytokines with proven regulatory activities of the immune responses. This study aimed to explore PBMCs' cytokine profiles in SSc patients versus controls, as well as to investigate the balance between pro- and anti-inflammatory cytokines in association with disease duration. PBMCs were isolated from 18 SSc patients and 17 controls and further subjected to in vitro stimulation with lipopolysaccharide and heat-killed Candida albicans. Cytokine production was measured after 24 h and 7 days, respectively, using ELISA kits for interleukin (IL)-1ß, IL-1 receptor antagonist (IL-1Ra), IL-6, tumor necrosis factor (TNF), IL-10, IL-17, and interferon-gamma (IFN-gamma). IL-1 ß, IL-6, and TNF levels were increased in SSc patients compared with healthy volunteers irrespective of the stimulus used. IL-1Ra and Il-17 concentrations were not statistically different between groups, even though a trend toward higher levels in patients compared with their matched controls was also observed. Most cytokines demonstrated a stable course with disease progression, except for IL-10 levels, which declined over time. In conclusion, the results of this pilot study reveal that in patients with SSc a persistently enhanced immune response is established and maintained regardless of stimulus or disease duration.

Efficacy and safety of upadacitinib in patients with active psoriatic arthritis and axial involvement: results from two phase 3 studies.

BACKGROUND: The objective of this post-hoc analysis was to assess the efficacy and safety of upadacitinib in psoriatic arthritis (PsA) patients with axial involvement. METHODS: Post-hoc analysis of SELECT-PsA 1 and SELECT-PsA 2 in patients randomized to upadacitinib 15 mg (UPA15), placebo (switched to UPA15 at week 24), or adalimumab 40 mg (ADA; SELECT-PsA 1 only). Axial involvement was determined by investigator judgement (yes or no; based on the totality of available clinical information, such as duration and characteristics of back pain, age of onset, and previous lab investigations and imaging, if available) alone, or investigator judgement and patient-reported outcome (PRO)-based criteria (Bath Ankylosing Spondylitis Disease Activity Index [BASDAI] ≥ 4 and BASDAI Q2 ≥ 4). Efficacy outcomes that describe axial disease activity, including BASDAI endpoints, such as change from baseline in the overall BASDAI score or proportion of patients achieving BASDAI50 (≥ 50% improvement from baseline), as well as Ankylosing Spondylitis Disease Activity Score (ASDAS) endpoints, such as mean change from baseline in overall ASDAS or proportion of patients achieving ASDAS inactive disease or low disease activity, were evaluated at weeks 12, 24, and 56, with nominal P-values shown. Treatment-emergent adverse events (TEAEs) are summarized through week 56. RESULTS: 30.9% of patients in SELECT-PsA 1 and 35.7% in SELECT-PsA 2 had axial involvement by investigator judgement alone; 22.6% (SELECT-PsA 1) and 28.6% (SELECT-PsA 2) had axial involvement by investigator judgement and PRO-based criteria. Greater proportions of patients achieved BASDAI50 with UPA15 versus placebo using either criterion, and versus ADA using investigator judgement alone, at week 24 in SELECT-PsA 1 (investigator alone: UPA15, 59.0%, placebo, 26.9%, P < 0.0001, ADA, 44.1%, P = 0.015; investigator and PRO-based: UPA15, 60.4%, placebo, 29.3%, P < 0.0001, ADA, 47.1%, P = 0.074), with comparable findings in SELECT-PsA 2. Similar results were observed with UPA15 for additional BASDAI and ASDAS endpoints at weeks 12 and 24, with improvements maintained at week 56. Rates of TEAEs were generally similar across sub-groups irrespective of axial involvement status. CONCLUSIONS: PsA patients with axial involvement determined by predefined criteria showed greater BASDAI and ASDAS responses with UPA15 versus placebo, and numerically similar/greater responses versus ADA. Safety results were generally comparable between patients with or without axial involvement. TRIAL REGISTRATION: ClinicalTrials.gov: SELECT-PsA 1, NCT03104400; SELECT-PsA 2, NCT0310437.

Treatment of relapsing polychondritis: a systematic review.

OBJECTIVES: Due to the rarity of relapsing polychondritis (RP), no randomised clinical trial has been conducted to date and treatment remains empirical. We performed a systematic literature review to assess the efficacy of the main conventional immunosuppressants and biotherapies used in RP. METHODS: We searched MEDLINE for original articles without language restriction. Abstracts from American College of Rheumatology (ACR) and European Alliance of Associations for Rheumatology (EULAR) were also considered for inclusion. Observational studies and clinical trials reporting on the efficacy of conventional immunosuppressants and biotherapies in adult patients with RP were selected and pooled response rates for each treatment were computed. RESULTS: Of 304 articles and abstracts identified, 31 underwent full-text review, and 11 were included. The studies involved a total of 177 patients, exposed to a total of 247 lines of treatments. The main treatments studied (by number of lines) were: TNF inhibitors (TNFi), n=92; methotrexate (MTX), n=38; tocilizumab (TCZ), n=26; anakinra (ANA), n=21; rituximab (RTX), n=16; abatacept (ABT), n=14; cyclophosphamide (CYC), n=14; azathioprine (AZA), n=13. The pooled response rates across studies were: 72% [95% CI: 42-95] for ABT, 66% [95% CI: 49-82] for TCZ, 64% [95% CI: 53-74] for TNFi, 56% [95% CI: 37-73] for MTX, 47% [95% CI: 26-68] for ANA, 43% [95% CI: 20-68] for RTX. Based on more limited data, response rates for AZA and CYC ranged from 38 to 100% and from 25 to 100%, respectively. CONCLUSIONS: In this systematic review of available evidence regarding the treatment of relapsing polychondritis, ABT, TCZ and TNFi were the drugs associated with the best outcomes. ABT efficacy must be interpreted in light of the small number of patients treated. While MTX had slightly less efficacy, it is one of the drugs for which data are the most robust.

Relapsing polychondritis: state of the art on clinical practice guidelines.

Due to the rarity of relapsing polychondritis (RP), many unmet needs remain in the management of RP. Here, we present a systematic review of clinical practice guidelines (CPGs) published for RP, as well as a list of the most striking unmet needs for this rare disease. We carried out a systematic search in PubMed and Embase based on controlled terms (medical subject headings and Emtree) and keywords of the disease and publication type (CPGs). The systematic literature review identified 20 citations, among which no CPGs could be identified. We identified 11 main areas with unmet needs in the field of RP: the diagnosis strategy for RP; the therapeutic management of RP; the management of pregnancy in RP; the management of the disease in specific age groups (for instance in paediatric-onset RP); the evaluation of adherence to treatment; the follow-up of patients with RP, including the frequency of screening for the potential complications and the optimal imaging tools for each involved region; perioperative and anaesthetic management (due to tracheal involvement); risk of neoplasms in RP, including haematological malignancies; the prevention and management of infections; tools for assessment of disease activity and damage; and patient-reported outcomes and quality of life indicators. Patients and physicians should work together within the frame of the ReCONNET network to derive valuable evidence for obtaining literature-informed CPGs.

Brief Report: Smoking in Systemic Sclerosis: A Longitudinal European Scleroderma Trials and Research Group Study.

OBJECTIVE: Data on the role of tobacco exposure in systemic sclerosis (SSc; scleroderma) severity and progression are scarce. We aimed to assess the effects of smoking on the evolution of pulmonary and skin manifestations, based on the European Scleroderma Trials and Research group database. METHODS: Adult SSc patients with data on smoking history and a 12-24-month follow-up visit were included. Associations of severity and progression of organ involvement with smoking history and the Comprehensive Smoking Index were assessed using multivariable regression analyses. RESULTS: A total of 3,319 patients were included (mean age 57 years, 85% female); 66% were never smokers, 23% were ex-smokers, and 11% were current smokers. Current smokers had a lower percentage of antitopoisomerase autoantibodies than previous or never smokers (31% versus 40% and 45%, respectively). Never smokers had a higher baseline forced expiratory volume in 1 second/forced vital capacity (FEV1 /FVC) ratio than previous and current smokers (P < 0.001). The FEV1 /FVC ratio declined faster in current smokers than in never smokers (P = 0.05) or ex-smokers (P = 0.01). The baseline modified Rodnan skin thickness score (MRSS) and the MRSS decline were comparable across smoking groups. Although heavy smoking (>25 pack-years) increased the odds of digital ulcers by almost 50%, there was no robust adverse association of smoking with digital ulcer development. CONCLUSION: The known adverse effect of smoking on bronchial airways and alveoli is also observed in SSc patients; however, robust adverse effects of smoking on the progression of SSc-specific pulmonary or cutaneous manifestations were not observed.

Polyarteritis Nodosa in Pregnancy.

BACKGROUND: Polyarteritis nodosa (PAN) is a rare disease that occurs predominantly in middle-aged males; its onset during pregnancy is exceptional. CASE REPORT: We present a case of PAN with peripartum onset in a patient with a twin pregnancy after ovarian stimulation for primary infertility. The pregnancy outcome was good in terms of the children's health. In the case of the mother, however, the presence of nonspecific signs and symptoms, a noncontributory ovarian biopsy, and mimics of a puerperal infection delayed the diagnosis of PAN. The emergence of a tender subcutaneous nodule on the forearm and its histopathologic findings were diagnostic. Treatment with pulse methylprednisolone and intravenous cyclophosphamide resulted in the patient's prompt recovery. CONCLUSION: We present the case to stress the value of careful physical examination in unveiling the presence of a rare disease.

Idiopathic inflammatory myopathies: state of the art on clinical practice guidelines [corrected].

Idiopathic inflammatory myopathies (IIMs) encompass a heterogeneous group of rare autoimmune diseases characterised by muscle weakness and inflammation, but in antisynthetase syndrome arthritis and interstitial lung disease are more frequent and often inaugurate the disease. Clinical practice guidelines (CPGs) have been proposed for IIMs, but they are sparse and heterogeneous. This work aimed at identifying: i) current available CPGs for IIMs, ii) patients ' and clinicians' unmet needs not covered by CPGs. It has been performed in the framework of the European Reference Network on rare and complex connective tissue and musculoskeletal diseases (ReCONNET), a network of centre of expertise and patients funded by the European Union's Health Programme. Fourteen original CPGs were identified, notably recommending that: i) extra-muscular involvements should be assessed; ii) corticosteroids and methotrexate or azathioprine are first-line therapies of IIMs. ii) IVIG is a treatment of resistant-DM that may be also used in other resistant-IIMs; iii) physical therapy and sun protection (in DM patients) are part of the treatment; v) tumour screening for patients with DM include imaging of chest, abdomen, pelvis and breast (in woman) along with colonoscopy (in patients over 50 years); vi) disease activity and damages should be monitor using standardised and validated tools. Yet, only half of these CPGs were evidence-based. Crucial unmet needs were identified both by patients and clinicians. In particular, there was a lack of large multidisciplinary working group and of patients ' preferences. The following fields were not or inappropriately targeted: diagnosis; management of extra-muscular involvements other than skin; co-morbidities and severe manifestations.

Redundant plantar skin folds.

A 46-year-old female patient presented with photosensitivity, symmetric arthritis, episodic plantar pain and strikingly redundant plantar skin folds, likely due to lipoatrophy after recurrent episodes of plantar panniculitis. In this context, leukopenia with lymphopenia, thrombocytopenia and positive antinuclear antibodies were revelatory for systemic lupus erythematosus. However, a small cerebriform plantar collagenoma, along with discrete dysmorphic features with downslanting palpebral fissures and mild right ptosis, second and third syndactyly and a larger first right toe since childhood, and early-onset bilateral ovarian cystadenoma, suggested a minimal Proteus syndrome. Genetic confirmation could not be performed. As adipose tissue dysregulation may be a feature of Proteus syndrome, the possible mechanisms leading to localized lipoatrophy in this setting are discussed. This case enlights intriguing links between adipogenesis, inflammation and dysmorphology. From a practical point of view, finding and treating an over-imposed inflammation could help limit damage in a hamartomatous syndrome.

Unilateral temporal myositis heralding polymyositis: ultrasonographic and elastographic findings. Case report.

Temporal myositis is a rare inflammatory disease of the temporal muscle. We report a case of unilateral temporal myositis, in which a polymyositis was diagnosed two years thereafter. Although focal myositis may rarely herald polymyositis, isolated temporal myositis preceding inflammatory myopathies has not been described, to our knowledge. In the setting of a temporal pain and swelling, ultrasonography may help in diagnosis, biopsy guidance, disease extension, and progression assessment. Further studies are necessary to establish the role of elastography in differentiating between muscle inflammation and hypertrophy.

The role of ultrasonography in assessing disease activity in patients with rheumatoid arthritis and associated fibromyalgia.

AIM: The purpose of this study is to compare and correlate US evaluation with clinical scores of the disease activity in patients with rheumatoid arthritis (RA) and concomitant fibromyalgia (FM). MATERIAL AND METHODS: Ten patients diagnosed with RA according to the 2010 ACR/EULAR classification criteria and associated FM based on the ACR 1990 classification criteria and two control groups, one with RA (10 patients) and one with FM (10 patients), were included. Clinical assessment was performed and the disease activity scores were calculated. Synovial/tenosynovial hypertrophy, fluid collections in grey scale (GS), and Power Doppler (PD) US assessed by US in the 28 joints included in the disease activity score 28 (DAS28). RESULTS: GS US score and PD US scores were correlated with DAS28 only in patients with RA (Pearson r coefficients 0.3 and 0.5). Mean DAS28 score was significantly higher in the RA/FM group, compared to RA and FM (5.6 versus 4.6 versus 4.5, respectively). Patients with RA/FM had similar median US scores to RA patients, while in FM group significantly lower median US scores were detected (16 versus 9.5 versus 0 for GS US and 3.5 versus 1.5 versus 0 for PD US, respectively). CONCLUSIONS: Disease activity scores should be interpreted with caution in patients with RA and FM. When available, US should be used to guide treatment decisions in patients with RA and FM.

Primary biliary cirrhosis--autoimmune hepatitis overlap syndrome associated with dermatomyositis, autoimmune thyroiditis and antiphospholipid syndrome.

Autoimmune liver diseases may be associated with extrahepatic autoimmune pathology. We report the case of a 52-year old woman who initially presented to the gastroenterology department for extreme fatigue, pale stools, dark urine and pruritus. Laboratory tests showed significant cholestasis and elevation of aminotransferase levels. Immunological tests revealed positive antinuclear (ANA=1:320) and antimitochondrial antibodies (AMA=1:40) with negative anti-smooth muscle and liver kidney microsomal type 1 antibodies. The biopsy was compatible with overlap syndrome type 1. The patient was commenced on immunosuppressive therapy according to standard of care (azathioprine 50mg, ursodeoxycholic acid and prednisone 0.5mg/kg), with moderate biochemical improvement. She subsequently developed proximal symmetrical weakness and cutaneous involvement and was diagnosed with biopsy-proven dermatomyositis. The immunosuppressive regimen was intensified to 150 mg azathioprine. At the three-month follow-up, her symptoms subsided and aminotransferases and muscle enzymes normalized. Upon further investigation the patient was diagnosed with autoimmune thyroiditis and antiphospholipid syndrome. To our knowledge, this is the first case of primary biliary cirrhosis - autoimmune hepatitis overlap syndrome associated with dermatomyositis, autoimmune thyroiditis and antiphospholipid syndrome.

Bone mineral density, vertebral fractures and body mass index in postmenopausal women with abdominal aortic calcification.

BACKGROUND: Evidence suggest that there are connections between osteoporosis and cardiovascular diseases. OBJECTIVES: The aim of the study was to analyze the relationship between radiological measurements of abdominal aorta calcifications (AAC) and bone mineral density (BMD) in postmenopausal women. METHODS: In this cross-sectional study were included 125 postmenopausal women 50-84 years of age. BMD of the spine and hip was measured by dual energy X-ray absorptiometry (DXA). AAC were assessed by lateral radiographs of lumbar spine (L1-L4), using the antero-posterior severity score (0-24). Vertebral fractures were evaluated from T4 to L4 using Genant's semiquantitative method. RESULTS: Forty-one (32.8%) patients had osteoporosis and 61 (48.8%) had AAC with a mean score of 3.1. Postmenopausal women with AAC were older and had significantly lower femoral neck and trochanteric BMD than subjects without AAC (all p < 0.01). There were no significant differences in the frequency of fractures between subjects with AAC and those without AAC (p > 0.05). In univariate analysis, age, height, weight, femoral and trochanter BMD were significantly associated with the severity of AAC score. In multiple regression analysis, femoral neck BMD, but not lumbar spine, trochanter BMD or age, was an independent predictor of AAC. CONCLUSIONS: Reduced femoral neck BMD is negatively associated with the presence of AAC in postmenopausal women. The association between BMD and AAC seems to be age-independent, which suggests a common pathogenesis for bone loss and vascular calcifications.

Systemic sclerosis-polymyositis overlap syndrome associated with autoimmune hepatitis and cerebral vasculitis.

Autoimmune hepatitis (AIH) is a chronic disorder characterized by persistent hepatocellular inflammation and necrosis. AIH overlap syndromes with other autoimmune diseases have been reported, including connective tissue diseases (CTD). Reports of AIH in systemic sclerosis (SSc), however, are scarce and have been particularly described in the limited SSc subtype. We report a case of systemic sclerosis-polymyositis overlap syndrome that developed AIH and subsequently, cerebral vasculitis. To our knowledge, this is the first report of such a complex mosaic of autoimmunity. We also review the literature regarding scleroderma-related AIH.

Is there a role for TNFα antagonists in the treatment of SSc? EUSTAR expert consensus development using the Delphi technique.

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.

Ultrasound findings in AL musculoskeletal amyloidosis.

Systemic AL amyloidosis is one of the differential diagnosis of chronic musculoskeletal disease, especially when swollen and painful joints is associated with claw hands. Ultrasound evaluation is a good diagnosis tool, showing a characteristic joint and tendon involvement and assisting in guided biopsy procedure. We report a 55 year old caucasian woman, diagnosed for two years with RA without improvement under different DMARDs, admitted for fixed flexion contractures of both hands ("claw hands"), worsening pain and swelling of small joints of hands and feet, elbows and shoulders. Pad shoulder sign and bilateral anterior wrist and elbow pads, macroglossia, thickened skin of fingers and ecchymotic rashes on forearm and around eyes were observed. Ultrasound examinations showed subdeltoid and bicipitoradial bursitis, presence of inhomogeneous hypoechoic material around bicipital tendons and tenosinovitis of the extensor tendons of the hand, and synovial thickening of elbow and shoulder joints. Complete analysis of the bone marrow biopsy and biopsy specimens from subacromial bursa were positive for AL amyloidosis.

Relative value of the lumbar spine and hip bone mineral density and bone turnover markers in men with ankylosing spondylitis.

The purpose of this study is to evaluate bone mineral density (BMD) and bone turnover markers in men with ankylosing spondylitis (AS) and to determine their relationship with clinical features and disease activity. Serum carboxi terminal cross-linked telopeptide of type I collagen (CTX), osteocalcin (OC) levels, and BMD of lumbar spine and proximal femur were evaluated in 44 males with AS, 18-60 years of age, and compared with those of 39 age-matched healthy men. Men with AS had a significantly lower BMD at the femoral neck and total hip as compared to age-matched controls (all p < 0.01). Osteopaenia or osteoporosis was found in 59.5% AS patients at the lumbar spine and in 47.7% at the femoral neck. Mean serum levels of OC and CTX were similar in AS patients and controls. There were no significant differences in BMD and bone turnover markers when comparing subgroups stratified according to disease duration or presence of peripheral arthritis. No correlations were found between disease activity markers and BMD or OC and CTX. In a cohort of relatively young males with AS, we found a high incidence of osteopaenia and osteoporosis. Disease activity and duration did not show any significant influence on BMD or serum levels of OC and CTX.

Causes and risk factors for death in systemic sclerosis: a study from the EULAR Scleroderma Trials and Research (EUSTAR) database.

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.

Treatment with infliximab in a patient with ankylosing spondylitis and Crohn's disease.

The association of Crohn's disease and ankylosing spondylitis is described in up to 30% of cases. Treatment of both conditions is not an easy task. We present the case of a 53 year old woman, diagnosed with colonic Crohn's disease and ankylosing spondilitis, treated initially with increasing doses of sulphasalazine and moderate dose of corticosteroids, with the persistence of severe gastrointestinal and articular symptoms. She underwent therapy with tumor necrosis factor alpha (TNFalpha) inhibitor infliximab, with a spectacular improvement of symptoms, signs and quality of life.
