Introduction Spinal subarachnoid haemorrhage is extremely rare in cases of subarachnoid haemorrhage and possesses servere characteristics. Additionally, spinal rheumatoid vasculitis is rare for spinal subarachnoid haemorrhage. The pathogenesis is unknown. Case presentation A 52-year-old woman with a 10-year history of seropositive rheumatoid arthritis was managed with leflunomide and celecoxib, and stable low disease activity was achieved. The patient had also been diagnosed with spinal subarachnoid haemorrhage secondary to isolated spinal rheumatoid vasculitis and obtained good therapeutic effects. Conclusion This is the first case to describe spinal subarachnoid haemorrhage secondary to isolated spinal vasculitis in a patient with rheumatoid arthritis, which provides more proof of anomalous neovascularization in the central nervous system in rheumatoid arthritis.

Rheumatoid arthritis (RA) is a chronic, inflammatory, systemic autoimmune disease, affecting the joints with varying severity among patients. The risk factors include age, gender, genetics, and environmental exposure (cigarette smoking, air pollutants, and occupational). Many complications can follow, such as permanent joint damage requiring arthroplasty, rheumatoid vasculitis, and Felty syndrome requiring splenectomy if it remains unaddressed. As there is no cure for RA, the treatment goals are to reduce the pain and stop/slow further damage. Here, we present a brief summary of various past and present treatment modalities to address the complications associated with RA.

Background The interferon pathways have been commonly implicated in autoimmune disease development but the identity of the genes involved has not yet been fully clarified. Variation in genes involved in interferon pathways is expected to have a role in the etiology of these diseases. Methods The potential association of a polymorphism in the IL28RA gene, involved in these pathways, with susceptibility to systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) and disease-related phenotypes was investigated in 603 Brazilian individuals (354 well-characterized SLE and RA patients, and 249 controls). IL28RA (rs4649203) variant was genotyped by TaqMan assay. Statistical analysis was performed including both diseases and a comprehensive list of patient clinical manifestations. Results The rs4649203-G (minor) allele was associated with SLE and RA occurrence and was shown to be a risk factor for serositis and anemia among SLE patients as well as a protective factor for rheumatoid vasculitis and rheumatoid nodules in RA patients, suggesting an association with a milder form of the disease. Conclusions The IL28RA gene may contribute to SLE and RA susceptibility and to specific clinical manifestations of the diseases.

Rheumatoid vasculitis (RV) is one of the most severe extra-articular manifestations of rheumatoid arthritis, with significant morbidity and mortality, requiring aggressive treatment with corticosteroids and/or immunosuppressants. Recently, biological drugs were included in its therapeutic armamentarium. The objective of this study was to perform a systematic review on the use of biological drugs in the treatment of RV. A systematic literature review was performed based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) recommendations and searching articles in MEDLINE/PubMed, Cochrane, SciELO, Scopus, and Virtual Health Library electronic databases. Secondary references were also evaluated. The methodological quality of the selected studies was evaluated by the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) criteria. Altogether, five articles, assessing the use of biological drugs, were included. Globally, 35 patients participated in the studies, of which 21 were treated with rituximab (RTX) in cycles of 1000 mg every 2 weeks; 9 used infliximab 5 mg/kg; 3 used infliximab 3 mg/kg; and 2 used etanercept 25 mg twice/week. In general, an improvement in clinical picture, reduction of the mean daily dose of corticosteroids, and improvement in the Birmingham Vasculitis Activity Score was achieved by the end of the treatment. Complete remission occurred in almost 70% of the cases. The adverse effect rate was 34%, mainly due to infections. There were two deaths, one due to sepsis and the other due to uncontrolled vasculitis, after the biological drug withdrawal, following the development of sepsis. Based on the results of the present review, we believe that the use of biological therapy such as RTX and anti-tumor necrosis factor α can be beneficial in treating this complication.

Cerebral rheumatoid vasculitis (CRV) is a rare, fatal, and diagnostically challenging disorder. We herein report an 81-year-old woman with a 4-year history of rheumatoid arthritis who presented with a fever, progressive disturbance of consciousness, high level of rheumatoid factor, and hypocomplementemia. The enhancement of the perforating branches in the left middle cerebral artery led us to suspect CRV. A brain biopsy could not be performed. After we intensified steroid therapy, the size of the cerebral lesions temporarily decreased. However, recurrence in the left frontal lobe occurred one month later, and the patient subsequently died. Early intensive treatments may be needed for CRV.

Aim To describe the clinical manifestations, evolution and treatment of patients with rheumatoid vasculitis. Methods Retrospective study (1975–2017) of all patients diagnosed with RV in 2 Rheumatology Services. Results A total of 41 patients were included, 17 (41.5%) males and 24 (58.5%) females; mean age at diagnosis: 67 ± 9 years; duration of rheumatoid arthritis: 10 ± 8.3 years. Most patients had erosive disease, 33 (80%). Rheumatoid factor and anticitrullinated antibodies were positive in all patients. Constitutional symptoms were present in 30 (73%) patients and extra-articular manifestations in 17 (41%) patients. The clinical manifestations of RV were mainly: cutaneous 28 (68%), and polyneuritis 26 (63%). All patients were treated with glucocorticoids. An immunosuppressant was associated in 24 (58.5%) patients. Five (12%) patients were treated with the association of glucocorticoids and a biologic treatment. The mortality after 2 years of follow-up was 33%, the most common causes being infection and progression of the vasculitis. The frequency of rheumatoid vasculitis has decreased over the last decade. Conclusion The clinical manifestations of RV were similar to previous studies. The frequency of RV seems to decrease. However, the clinical picture and severity remains invariable.

Malignant rheumatoid arthritis (MRA) is defined as rheumatoid arthritis (RA) with systemic vasculitis or other severe extra-articular manifestations. Japan has a nationwide database for MRA. We analyzed the characteristics of Japanese patients with MRA based on data from the Ministry of Health, Labour and Welfare (MHLW).We were permitted to use data on 43,108 patients who were registered in the MHLW database from 2003 to 2013.Median age was 65 (interquartile range, 57-72) years. Patients consisted of 71% females. Proportions of patients who had or had experienced interstitial pneumonia and pleuritis were increased, episcleritis was stable, and other MRA manifestations were decreased over time. The number of positive symptoms per patient also decreased over time. The median dose of glucocorticoid, percentage of patients undergoing surgery, and use of non-steroidal anti-inflammatory drugs and apheresis decreased year by year. Steinbrocker stage and class improved over time. Median C-reactive protein levels and erythrocyte sedimentation rate also decreased. Regarding social productivity levels of patients with MRA, the proportion of patients who were working or working from home increased and the proportion of patients recuperating or hospitalized decreased.In patients with MRA, disease activity decreased and social productivity improved from 2003 to 2013.

Rheumatoid vasculitis (RV) usually occurs in patients with refractory rheumatoid arthritis (RA). An 80-year-old woman was transferred to our hospital because of muscle weakness and paresthesia in all 4 limbs. She had been diagnosed with RA 30 years ago and achieved sustained clinical remission. At presentation, polyarthritis and drop foot were observed, and rheumatoid factor was prominently elevated. A peripheral nerve conduction test revealed mononeuritis multiplex in her limbs. We suspected that RV had developed rapidly despite RA having been stable for many years and started immunosuppression therapy with steroids combined with azathioprine. The treatment prevented worsening of muscle weakness and paresthesia.

An 80-year-old woman with rheumatoid arthritis presented with chest pain. Clinical examination revealed new-onset paroxysmal atrial fibrillation with symptomatic sinus pauses and worsening mitral regurgitation, which were both resistant to conventional therapies. Based on her skin lesions, an increase in pleural and pericardial effusion, possible myocardial involvement, and a positive finding for immune complex testing, rheumatoid vasculitis was diagnosed. Subsequent glucocorticoid therapy suppressed systemic inflammation, resulting in structural, functional, and electrical reverse remodeling of the left atrium with complete remission of atrial arrhythmias and also an improvement of mitral regurgitation. This case highlights the importance of evaluating the underlying disease activity in a case of de novo paroxysmal atrial fibrillation associated with systemic autoimmune disease.

Background Central nervous system affection in rheumatoid arthritis is rare. The most frequently encountered neurological complications with rheumatoid arthritis are peripheral neuropathy and atlantoaxial subluxation with subsequent spinal cord compression. Cerebral rheumatoid vasculitis is not a common complication. Case presentation A 60-year-old Egyptian female with history of rheumatoid arthritis for 15 years presented with headache and receptive aphasia. Computed tomography scan of the brain showed recent intracerebral hemorrhage. Digital subtraction cerebral angiography showed moyamoya syndrome angiographic pattern as sequelae of intracranial vasculitis. The patient did well with conservative management. Conclusion Cerebral rheumatoid vasculitis is rare, but can be a life-threatening condition. Early management of rheumatoid arthritis is essential to prevent such serious complication.

Aortitis is an inflammatory phenomenon involving one or more layers of the aorta and can have infectious or noninfectious etiologies. Complications of aortitis include aneurysm, dissection, and rupture, which can lead to ischemic organs and ultimately death. Noninfectious aortitis is often secondary to trauma or results from a systemic inflammatory process. It is further categorized based on clinical characteristics, laboratory findings, and imaging. There are some cases in which the etiology cannot be determined and is, therefore, idiopathic in nature. We present a case of a 67-year-old male who presented with malaise, abdominal pain, anorexia, and significant weight loss for several months. Imaging revealed retroperitoneal fibrosis and aortitis. After an extensive workup, we diagnosed idiopathic aortitis and treated the patient with high-dose corticosteroids that led to symptom improvement.

Rheumatoid vasculitis is a rare, extra-articular manifestation that can be seen in long-standing rheumatoid arthritis. Here we present the case of a 51-year-old man who presented with arthralgias, skin rash, dyspnoea and generalized leg swelling and who was diagnosed with rheumatoid arthritis flare. LEARNING POINTS: Extra-articular manifestations like rheumatoid vasculitis and pericarditis rarely present as initial manifestations of rheumatoid arthritis. A high index of suspicion is required to make the diagnosis, especially in an adult who presents with multiorgan manifestations, rash, and a high titre of rheumatoid factor and anti-CCP antibody levels.

Episcleritis and scleritis are the most common ocular inflammatory manifestation of rheumatoid arthritis. Rheumatoid arthritis (RA) accounts for 8% to 15% of the cases of scleritis, and 2% of patients with RA will develop scleritis. These patients are more likely to present with diffuse or necrotizing forms of scleritis and have an increased risk of ocular complications and refractory scleral inflammation. In this review we provide an overview of diagnosis and management of rheumatoid arthritis-associated episcleritis and scleritis with a focus on recent treatment perspectives. Episcleritis is usually benign and treated with oral non-steroidal anti- inflammatory drugs (NSAIDs) and/or topical steroids. Treatment of scleritis will classically include oral NSAIDs and steroids but may require disease-modifying anti-rheumatic drugs (DMARDs). In refractory cases, treatment with anti TNF biologic agents (infliximab, and adalimumab) is now recommended. Evidence suggests that rituximab may be an effective option, and further studies are needed to investigate the potential role of gevokizumab, tocilizumab, abatacept, tofacitinib, or ACTH gel. A close cooperation is needed between the rheumatology or internal medicine specialist and the ophthalmologist, especially when scleritis may be the first indicator of an underlying rheumatoid vasculitis.

Marantic endocarditis is an extremely rare extra-articular complication of rheumatoid arthritis. To date, documented cases typically occurred in the absence of other systemic features of disease activity. We report a rare and exceptional example of marantic endocarditis secondary to fulminant systemic rheumatoid vasculitis with multi-organ disease. Findings from this case and literature review suggest that marantic endocarditis associated with rheumatoid vasculitis displays a tendency to affect the mitral valve with high risk of embolization.

Rheumatoid vasculitis which affects small-to-medium-sized vessels is a rare and late complication of rheumatoid arthritis. It is defined histologically as immune complex deposition in venules, capillaries and arterioles.1 Vasculitis in the vasa nervorum leads to infarction of peripheral nerves which leads to neuropathy. We present a case of mononeuritis multiplex due to rheumatoid vasculitis.

Objective.To characterize the indication, outcomes, and adverse effects of rituximab (RTX) treatment in a large single-center cohort of patients with systemic rheumatoid vasculitis (RV).Methods.We retrospectively reviewed the medical charts of 17 patients treated with RTX for systemic RV from 2000 to 2017. Clinical characteristics, outcomes, and adverse effects were analyzed.Results.At RV diagnosis, mean age was 59 years, 59% were female, 94% were white, and 82% had positive rheumatoid factor. At the time of initiating RTX, median Birmingham Vasculitis Activity Score for rheumatoid arthritis was 4.0 (interquartile range 2.0–7.5). RV presented in the skin in 8 patients (47%), as mononeuritis multiplex in 2 (12%), inflammatory ocular disease in 2 (12%), and affected multiple organ systems in 5 (29%). RTX was used for induction therapy in 8 patients (47%), relapsing RV in 4 (24%), second-line therapy in 2 (12%), and salvage therapy or in combination with another agent in 3 (18%). At 3 months, 2 (13%) of 15 patients with available followup information achieved complete remission (CR), and 10 (67%) achieved partial response (PR). At 6 months, 6 patients (40%) achieved CR, 8 (53%) achieved PR, and one had no response. At 12 months, 8 of 13 patients with available records (62%) had CR and 5 patients (38%) had PR.Conclusion.Systemic RV is difficult to treat effectively. CR of RV was achieved in 62% and PR in 38% of patients within 12 months of RTX use. Further evidence is needed to inform treatment for patients with RV.

Rheumatoid vasculitis is a rare etiology for pulmonary hypertension (PH) in patients with connective tissue disease. We encountered a case of acute PH crisis in a case with rheumatoid vasculitis eight months after undergoing adalimumab reduction. Since no repetition of arthralgia occurred after the adalimumab reduction, we decided to not increase the dose of adalimumab. However, hemodynamic collapse thereafter developed and even though steroid pulse therapy was administered, the patient nevertheless died. The autopsy showed clusters of acute and chronic inflammation around the remodeled pulmonary arteries along with micro-thrombi in the vessel lumen. We should consider the possibility of critical worsening of PH as a phenotype of vasculitis related to immunosuppressive therapy reduction.

Polyarteritis nodosa (PAN) is a rare multisystem vasculopathy that predominantly affects medium-sized arteries. Involvement of the cardiac and/or pulmonary vasculature may be fatal. We describe a 67-year-old Japanese male who presented with multiple coronary artery aneurysms and subsequently developed lower extremity gangrene. A diagnosis of PAN was established based on the correlation of clinical presentation and laboratory and imaging findings. In addition, we review other manifestations of PAN and differential considerations for this rare but potentially lethal condition.

ObjectivePeripheral ulcerative keratitis (PUK) is a rare but severe ocular complication of rheumatoid arthritis (RA). It can be considered as an ocular manifestation of rheumatoid vasculitis (RV). Our case series aimed to evaluate the efficacy of rituximab (RTX) for PUK occurring in patients with RA.MethodsStudy population were patients with RA-associated PUK treated with RTX 1000 mg on days 1 and 15 at least once after the diagnosis. We identified patients referred to the rheumatology and ophthalmology departments of our hospital between February 2014 and June 2020. We also included patients referred by their specialist after being contacted through the Club Rhumatismes et Inflammation. Demographic data and clinical and biological features were retrospectively collected.ResultsWe included seven patients (three men and four women, median age 58 years). All but one had a long-standing RA with a median disease duration of 13.9 years (IQR 0–30.2). RA was erosive in six out of seven patients. All patients had rheumatoid factors and anticitrullinated peptides antibodies were positive in six of them. PUK was complicated by corneal perforation in three patients and required surgery. After a median follow-up of 29.8 months (IQR 5–75), corneal inflammation was controlled in all patients. PUK recurred in one patient, 8 months after a single infusion of RTX. 71% of the patients presented a good articular response. No patient developed other manifestations of RV. No serious adverse event related to RTX was observed.ConclusionRTX appears to be an efficient and safe therapeutic option in the treatment of RA-associated PUK.

We describe a fatal case of diffuse alveolar hemorrhage (DAH) complicated by rheumatoid arthritis (RA). A female patient was diagnosed with RA two months earlier and was treated with prednisolone and tacrolimus due to abnormalities in chest images. The patient was admitted to Hamanomachi Hospital for exertional dyspnea and was treated for exacerbation of chronic heart failure. Even after treatment for heart failure, exertional dyspnea remained. Chest CT imaging revealed contractile, patchy consolidations and ground-glass opacities (GGO) with a peribronchial distribution, suggesting an organizing pneumonia (OP) pattern. She was then treated with an additional 25 mg/day of prednisolone following a clinical diagnosis of OP. When the prednisolone dose was tapered, chest imaging showed worsening infiltration. A bronchoscopy was conducted, and bronchoalveolar lavage fluid was sanguineous, indicating DAH. Given that additional workup for the other etiology of DAH was negative, DAH was thought to be related to RA. Intensive treatment, including pulse dose methylprednisolone, failed to halt progression of respiratory failure, leading to a fatal outcome. The clinical presentation proved challenging due to its rarity. DAH might be a differential diagnosis in RA patients with consolidations and GGO in chest CT images. We review past cases of RA-associated DAH and assess potential treatment choices for future cases.

Rheumatoid arthritis (RA) is the most common multisystemic autoimmune inflammatory joint disorder, affecting nearly 1.3 million adults in the US. RA has high economic and social burdens. Functional disability may arise in RA from the characteristic chronic progressive inflammation and the erosion of multiple joints and cartilage damage. Systemic manifestations of RA include rheumatoid nodules, pleuropulmonary complications, pericarditis, rheumatoid vasculitis, Felty’s syndrome (the rare triad of rheumatoid arthritis, splenomegaly, and neutropenia), amyloidosis, and neurological complications. We present the diagnostic challenges of differentiating pleuropulmonary and pericardial complications of rheumatoid arthritis from side effects of therapy (rheumatoid pleural and pericardial effusions vs immune suppression associated side effects and infections). We use the Naranjo score to facilitate this decision-making process. A 52-year-old man with a history of RA, chronic small right pleural effusion, and hypertension on long-term oral methotrexate and corticosteroid therapy presented to the emergency room after 1 week of worsening respiratory symptoms. A chest radiograph demonstrated a large pleural effusion and pneumonia. Intravenous methylprednisolone and antibiotics were administered. A video-assisted thoracoscopic procedure was performed, chest tubes were inserted, and abatacept was eventually initiated as adjunctive therapy to methotrexate and corticosteroid therapy for the rheumatoid arthritis and lung condition. Abatacept is an immunosuppressive fusion protein composed of the Fc region of immunoglobulin G1 fused to the extracellular domain of cytotoxic T-lymphocyte-associated protein 4, which interferes with the immune activity of T cells.

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disorder characterized by excessive systemic inflammation, caused by uncontrolled activation of lymphocytes and macrophages, which secrete increased amounts of cytokines. HLH may be caused by gene mutations (primary HLH) or associated with malignancy, immunodeficiency, infection or autoimmune disease (secondary HLH). A 58-year-old woman with seropositive rheumatoid arthritis (RA) presented with fever, ulcers on the left foot and in the intergluteal cleft and increased inflammation markers. Clinical and laboratory evaluation, combined with findings from intra-arterial digital subtraction angiography of the lower limbs, pointed towards the diagnosis of vasculitis. Intravenous administration of low-dose cyclophosphamide resulted in recession of fever and decrease of inflammation markers. However, the patient later developed pancytopenia, hepatomegaly, hyperferritinemia, hypofibrinogenemia and hypertriglyceridemia, while bone marrow aspiration demonstrated hemophagocytosis. The diagnosis of HLH was established. An extensive workup excluded malignancies, systemic infections and immunodeficiencies. HLH in our patient was attributed to activation of RA and presentation of vasculitis. Treatment with corticosteroids and intravenous immunoglobulin led to resolution of fever, correction of pancytopenia and complete healing of the ulcers. Timely diagnosis and treatment of HLH is highly important for a favorable outcome for the patients. Treatment of secondary HLH associated with autoimmune diseases involves corticosteroids and/or other immunomodulatory agents, such as intravenous immunoglobulin.

Systemic inflammatory disorders frequently involve the skin, and when cutaneous disease develops, such dermatologic manifestations may represent the initial sign of disease and may also provide valuable prognostic information about the underlying disorder. Familiarity with the various skin manifestations of systemic disease is therefore paramount and increases the likelihood of accurate diagnosis, which may facilitate the implementation of an appropriate treatment strategy. An improvement in quality of life and a reduction in the degree of morbidity may also be a realized benefit of accurate recognition of these skin signs. With this context in mind, this review highlights the salient clinical features and unique dermatologic manifestations of rheumatoid arthritis, adult-onset Still's disease, and the crystal arthropathy, gout.

Balloon angioplasty can cause shear stress and tear of the vascular endothelium during mechanical dilatation, leading to increased inflammation and coagulation reactions of the vascular endothelium. Herein, a worst case of active rheumatoid vasculitis is described, where due to progressing ischemic necrosis of the leg, endovascular intervention was unavoidably performed in the presence of active rheumatoid vasculitis. After percutaneous balloon angioplasty, the patient developed recurrent thrombotic occlusion of the leg arteries, and finally, limb amputation resulted in despite vigorous treatment including medication, immunosuppression, catheter-directed thrombolysis, and post-thrombolysis anticoagulation. This case report indicates that endovascular intervention may be detrimental to the active rheumatoid vasculitis. Until the development of treatment guideline to prevent or control inflammatory reaction, endovascular intervention for the active rheumatoid vasculitis may not be appropriate as a first line therapy even though there is progressing ischemic necrosis.

Granulomatous disorders comprise a large family sharing the common histological denominator of granuloma formation. Collagenolytic or necrobiotic granuloma is one in which a granulomatous infiltrate develops around a central area of altered collagen and elastic fibers. The altered fibers exhibit new staining patterns, becoming either more basophilic which gives blue appearance (“blue granuloma”) or eosinophilic giving red appearance (“red granuloma”). Conditions which exhibit blue granuloma include granuloma annulare, Wegener's granulomatosis, and rheumatoid vasculitis, whereas red granulomas include necrobiosis lipoidica, necrobiosis xanthogranuloma, rheumatoid nodules, Churg-Strauss syndrome, and eosinophilic cellulitis (Well's syndrome).

Neurologic manifestations of rheumatoid arthritis (RA) range in severity from mild paresthesias in the hand from carpal tunnel syndrome to sudden death due to impingement of the medulla by an eroded, vertically subluxed dens. Most neurologic complications are a consequence of articular inflammation and damage that leads to compression of adjacent structures of the central or peripheral nervous systems. Rare but serious extra-articular manifestations include inflammation of the meninges and ischemic neuropathies due to necrotizing arteritis of the vasa vasorum. Medical therapy with synthetic disease-modifying antirheumatic drugs and biological agents has diminished the incidence of serious neurologic manifestations in RA.

In this article, we discussed leukocytapheresis (LCAP) for rheumatoid arthritis (RA). Recently, a simple and practical on-line continuous LACP system has been developed. It is equipped with a direct hemoperfusion column (Cellsorba®, Asahikasei Medical Co., Ltd.) packed with fine-diameter polyester fibers, which are commonly used to adsorb white blood cells to prevent a graft-versus-host reaction during blood transfusion. Clinical trials revealed that LCAP is a effective and safe therapy for patients with drug-resistant RA or RA complicated with vasculitis. Because the procedure is simple and requires no plasma substitutes and the volume needed for extracorporeal circulation is less than that for other plasmapheresis, LCAP might be accepted as an optional therapeutic modality for active RA that was refractory to conventional drug therapy including biological agents. The mechanism of the efficiency of LCAP on RA is unclear. LCAP may cause a reduction of activated T cells from affected joints, down-regulation of Pgp on helper T cells and restoration of Treg function, and that may modify the abnormal cytokine balance. These findings may explain some of the mechanisms by which the articular symptoms are improved by LCAP.

The purpose of this study is to report the efficacy and safety of a combination of tocilizumab (TCZ) and high-dose corticosteroid (CS) in two patients with microscopic polyangiitis (MPA) and review the published current clinical evidence on TCZ in patients with anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV), except for large vessel vasculitis (LVV) and polymyalgia rheumatica (PMR). Two MPA patients were treated with TCZ at 8 mg/kg every month for 1 year and CS (prednisolone 1 mg/kg/day for 2 weeks, followed by tapering) in a prospective single-arm, single-center, cohort, open-label pilot study (UMIN clinical trials: 000012072). We performed a systematic literature search (PubMed and ICHUSHI [Japan Medical Abstracts Society] until June 30, 2017) to identify published reports on patients with all vasculitis other than LVV/PMR, who were treated with TCZ. We successfully treated the first patient. However, the other patient had serious infection probably associated with the combination of TCZ and high-dose CS. The literature review identified 22 reports with a total of 34 patients who received TCZ for AAV, rheumatoid vasculitis, and other types of vasculitis, in addition to our patients. In 15 of 17 patients (88.2%) with primary and secondary AAV, especially MPA, TCZ induced clinical remission, although TCZ use for rheumatoid vasculitis and vasculitis with mucocutaneous lesions is controversial. This study suggested that TCZ therapy is a potential treatment strategy for patients with AAV. However, TCZ combined with high-dose of CS might not be an appropriate treatment. Future studies are needed to confirm our findings.

When patients with autoimmune diseases, such as rheumatoid arthritis (RA), are treated with potent immunosuppressive therapy, the risk of opportunistic diseases inevitably increases. If patients have the misfortune to suffer from both opportunistic and active autoimmune diseases, correct diagnosis could sometimes be difficult since both diseases have inflammatory nature. The choice of treatment is another challenge in that aggressive immunosuppressive therapy can fuel the opportunistic infection. Here we report a case of RA patient with new onset rheumatoid vasculitis that was diagnosed in the process of treatment of Pneumocystis jirovecii pneumonia.

SummaryBackground and objective There have only been few studies examining rheumatoid arthritis (RA)-related skin manifestations in larger patient populations. Herein, we present current data on the prevalence and spectrum of cutaneous lesions in RA, addressing disease activity scores, anti-CCP antibodies as well as novel pharmacological approaches. Patients and methods Between November 2006 and July 2007, 214 patients with RA treated at the Division of Rheumatology, University Hospital Jena, Germany, were prospectively examined. Results 27.5 % of patients exhibited RA-related skin manifestations, almost all of which were rheumatoid nodules. These lesions occurred significantly more frequently in patients with longstanding disease, those testing positive for rheumatoid factor and anti-CCP-antibodies, as well as individuals on leflunomide and TNF-alpha antagonists. Comparatively lower prevalence rates were observed for palisading neutrophilic and granulomatous dermatitis and rheumatoid vasculitis. Conclusions Despite increasingly early treatment of RA and use of novel pharmacological agents, there is a high prevalence of rheumatoid nodules, which represent the most common cutaneous manifestation in RA. The higher prevalence of rheumatoid nodules in patients on leflunomide and TNF-alpha antagonists might be an indication that pharmacological treatment has only limited effects on their formation, possibly due to pathogenetic pathways that are only inadequately affected by drug therapies. By contrast, palisading neutrophilic and granulomatous dermatitis and rheumatoid vasculitis appear to respond better to novel pharmacological agents.

Vasculitis has been described in most types of inflammatory arthritis. The best described and most widely recognised form is rheumatoid vasculitis. The incidence of systemic rheumatoid vasculitis has declined significantly following the general early use of methotrexate in the 1990s, and it is now a rare form of vasculitis. Treatment of rheumatoid vasculitis is conventionally with glucocorticoids and cyclophosphamide, but there is an increasing role for rituximab similar to that in other types of vasculitis. Despite these developments the mortality of rheumatoid vasculitis remains high. Vasculitis in other types of inflammatory arthritis is less well described and the treatment remains empirical.

Abatacept (Orencia) is a recombinant fusion protein of cytotoxic T-lymphocyte–associated antigen-4 and human immunoglobulin that inhibits T-cell activation and proliferation by binding to CD80 and CD86 on antigen-presenting cells and prevents binding to CD28 on T cells.1 The drug is approved by the US Food and Drug Administration to treat adult rheumatoid arthritis, juvenile idiopathic arthritis, and, more recently, psoriatic arthritis. Reported cutaneous reactions after treatment with abatacept, including rheumatoid vasculitis, cutaneous polyarteritis nodosa localized to the infusion site, pyoderma gangrenosum, erythema elevatum diutinum, psoriasis, and Sweet syndrome, have mostly been described in patients with rheumatoid arthritis.2, 3, 4, 5 We present a patient who had small- and medium-vessel vasculitis presenting as numerous lower leg ulcers after treatment with abatacept for psoriasis and psoriatic arthritis.

Rheumatoid vasculitis (RV) is an infrequent complication of longstanding severe rheumatoid arthritis (RA). The active vasculitis associated with rheumatoid disease occurs in about 1%-5% of the patient population. RV is a manifestation of "extra-articular" rheumatoid arthritis and involves the small- and medium-sized arteries in the body. Newer RA treatments, including biologic therapies, offer a broader array of potential therapeutic options, although no controlled trials exist to guide treatment. In general, following tissue confirmation of the diagnosis, the severity of organ involvement and disease manifestations can guide treatment decisions. We want to alert clinicians of this unique yet severe complication of RA which has high morbidity and mortality. We describe a thought-provoking case of a 44-year-old male with past medical history (PMH) of hypertension who presented with over three-month history of lower extremity (LE) swelling, discoloration, and ulceration. Arthralgias with constitutional symptoms (fatigue, weight loss), large pericardial effusion, was found to have leukocytoclastic vasculitis along with rheumatoid factor (RF) >650, and anti-cyclic citrullinated peptide (anti-CCP) antibodies >300, low C4 and normal C3. Pericardial fluid appeared serous, exudative, showed histiocytes, multinucleated giant cells and necrotic debris consistent with rheumatoid effusion. Skin, right shin, punch biopsy showed epidermal necrosis from underlying occlusive vasculopathy. Skin, left lower back, punch biopsy showed focal leukocytoclastic vasculitis. The patient was started on high dose steroids with marked improvement in the symptoms, Rituximab was planned awaiting QuantiFERON to be negative. Pan-CT angiography of the whole body was negative for any vascular changes ruling out polyarteritis nodosa (PAN).

Rheumatoid vasculitis (RV) occurs in patients with long-standing rheumatoid arthritis (RA) or high levels of immunological factors and can result in devastating cardiovascular (CV) events. Here we report a case of a 38-year-old male who presented with hypertensive emergency and intracerebral hemorrhage (ICH). In the literature, a few observational studies have indicated the association of RA with hypertension; however, little evidence exists supporting a direct relationship between RA and ICH. In this case, we attempted to evaluate the complex relationship between all of these factors and found that early detection and treatment of RA may be beneficial in reducing ICH; however, large studies in the future are warranted to validate our observation.

ObjectivesTo document the current training, implementation and role of modern musculoskeletal imaging techniques: ultrasound, magnetic resonance imaging, computed tomography and positron emission tomography, among rheumatologists in the member countries of the EULAR.MethodsEnglish-language questionnaires for each imaging modality developed by a EULAR task force were sent out to national and international scientific societies as well as imaging experts in the given modalities involved in research and/or training. The surveys were distributed via an online survey tool (SurveyMonkey). Simple descriptive and summary statistics were calculated from the responses.ResultsMore than 90% of ultrasound (US) experts reported the availability of a US unit in their department. Suspicion of rheumatoid arthritis and spondyloarthritides were the main clinical indications for performing US for diagnostic purposes. Suspicion of sacroiliitis and degenerative spine disease were the most common indications to perform magnetic resonance imaging (MRI) or computed tomography (CT) for diagnostic purposes, while positron emission tomography was mainly performed to diagnose large vessel vasculitis and to investigate fever of unknown origin. The reported percentage of rheumatologists performing US was highly variable, ranging from more than 80% in 6% of countries to less than 10% in 15% of countries. The majority of experts (77%) reported that their national rheumatology societies organise musculoskeletal US courses, while courses in MRI or CT organised by the national rheumatology societies were less commonly reported (29% and 8%, respectively).ConclusionsRheumatologists in Europe utilise modern imaging techniques; however, access to the techniques and training offered is varied.

Rheumatoid arthritis (RA) is associated with a wide variety of extra-articular manifestations and comorbidities, several of which can be organ- or even life-threatening. These extra-articular manifestations and comorbidities can also contribute to the physical disability and psychological morbidity of RA that lead to reduced quality of life, higher direct and indirect costs, and societal burden of the disease. Although the expansion of RA treatment options and adoption of treat-to-target approaches has reduced the incidence and severity of several nonarticular manifestations of RA, such as rheumatoid vasculitis and cardiovascular disease events, this does not seem to be shared by all RA comorbidities. Moreover, a number of highly prevalent and impactful RA-driven comorbidities, such as accelerated atherosclerosis, interstitial lung disease, and sarcopenia, can present clinically in the years before the manifestation of joint pain or observable synovitis. A larger proportion of patients with RA have atherosclerosis, myocardial dysfunction, interstitial lung disease, and sarcopenia that is subclinical in the preclinical and earliest clinical phases of RA, emphasizing the importance of targeting the pre-RA phase for the prevention of comorbidities that are often poorly responsive to treatment once they develop. Herein, we review the potential impact of pre-RA prevention on the incidence and burden of extra-articular manifestations and nonarticular comorbidities.
