Targeting complement dysregulation: eculizumab in scleroderma renal crisis management-a case-based review.

Systemic sclerosis (SSc) poses significant challenges in clinical management, especially when complicated by scleroderma renal crisis (SRC), a rare but life-threatening manifestation. Here, we report a 41-year-old female patient with SSc who presented with SRC and concurrent thrombotic microangiopathy. Her condition persisted despite conventional treatments such as plasma exchange and renin-angiotensin-aldosterone system blockade. In particular, treatment with eculizumab, a C5 complement inhibitor, led to a rapid improvement in platelet count, reduction in lactate dehydrogenase levels, and complete recovery of renal function. Genetic testing revealed a variant of unknown significance in the thrombomodulin (THBD) gene, which is associated with the complement system. This case highlights the complex interplay between complement dysregulation and SRC, and highlights the promising role of eculizumab in refractory cases. Further investigation of complement involvement and the efficacy of eculizumab in SRC warrants attention to improving therapeutic outcomes in this challenging condition.

De novo manifestations during adalimumab treatment in Behçet's syndrome.

OBJECTIVES: Treatment response may be variable across organ manifestations of Behçet syndrome (BS). We aimed to determine the frequency of de novo manifestations during adalimumab treatment. METHODS: We conducted a chart review of all BS patients who received adalimumab in our center between 2008 and 2023. Demographic data, reasons for initiating adalimumab, concurrent medications, previous treatments, and outcomes were recorded. We defined de novo manifestations as new BS manifestations that occurred for the first time during treatment with adalimumab. For patients with vascular involvement, a new vascular event at another vessel was also considered as a de novo manifestation. RESULTS: Among the 335 patients, a de novo manifestation developed in 14 (4%) patients. De novo manifestations were vascular involvement in 5 patients, arthritis in 3, anterior uveitis in 2, nervous system involvement in 2, gastrointestinal involvement in 1, and epididymitis in 1 patient. The primary reasons for adalimumab treatment were vascular involvement in 5 patients, uveitis in 4, arthritis in 3, mucocutaneous involvement in 1, and epididymitis in 1 patient. Upon the development of de novo manifestation, adalimumab was switched to another biologic in 4 patients, dose was intensified in 3, colchicine, conventional immunosuppressives, and/or glucocorticoids were added in 5, and topical eye drops were added in 2 patients, leading to remission of de novo manifestations in all patients. CONCLUSION: De novo manifestations were infrequent (4%) among BS patients treated with adalimumab. Of these, 57% were major organ involvement, mainly vascular involvement. None of the patients developed posterior uveitis.

Sexual dysfunction among female patients with rheumatic diseases.

To demonstrate the burden of sexual dysfunction (SD) among females with rheumatic diseases, we conducted a cross-sectional comparative study in patients with systemic sclerosis (SSc), systemic lupus erythematosus (SLE), and Behçet's syndrome (BS) along with suitable healthy controls (HCs). Age-matched female patients with SSc (n = 50), SLE (n = 49), and BS (n = 54), along with 52 female HCs were included in this study between April and October, 2021. Sociodemographic features were recorded, and psychometric tests, i.e., female sexual function index (FSFI), Beck depression inventory (BDI), body cathexis scale, and marital adjustment test (MAT) were performed. Scale scores were compared, and binary logistic regression was used to identify predictors for SD in the whole group. The total FSFI and body cathexis scores among the patient groups were significantly lower than those of the HCs (p < 0.001). Depression was significantly more frequent in the patient groups. MAT scores did not differ significantly between the study groups. Patients with SSc had the worst scores in each psychometric index, including MAT. Decreased body cathexis score [OR 0.974, 95% CI (0.957-0.991), p = 0.003] and low MAT score [OR 0.937, 95% CI (0.896-0.980), p = 0.005], and being diagnosed with SSc [OR 6.6, 95% CI (1.975-22.498), p = 0.002], SLE [OR 2.7, 95% CI (0.998-7.753), p = 0.050], and BS [OR 2.8, 95% CI (1.100-7.359), p = 0.031], were identified as independent predictors for SD. Body cathexis seems to be the most important independent predictor for SD, and the burden of SD appears heavier in patients with SSc, probably due to poor body image satisfaction.

Brain white matter microstructural alterations in Behcet's syndrome correlate with cognitive impairment and disease severity: A diffusion tensor imaging study.

OBJECTIVES: To evaluate the microstructural integrity of brain white matter tracts in patients with Neuro-Behcet's syndrome (NBS) and Behcet's syndrome (BS) without neurological manifestations using diffusion tensor imaging (DTI) and to investigate potential utility of DTI as a surrogate biomarker of neurocognitive functioning and disease severity. METHODS: This cross-sectional study comprised 34 NBS patients and 32 BS patients without neurological involvement, identified based on the International Study Group of the Behcet's disease (ISGBD) and the International Consensus Recommendation (ICR) criteria, as well as 33 healthy controls. Cognitive functions, including attention, memory, language, abstraction, executive control, visuospatial skills, and sensorimotor performance were assessed using standardized questionnaires. DTI data were analyzed using tract-based spatial statistics (TBSS) and automated probabilistic tractography to investigate inter-group differences. Subsequently, correlations between tensor-derived parameters of white matter tracts, neurocognitive test scores, and disease severity measures were examined. RESULTS: DTI revealed decreased fractional anisotropy and increased radial diffusivity, mean diffusivity, and axial diffusivity in both supratentorial and infratentorial white matter in NBS patients, indicating widespread loss of microstructural integrity. Moreover, this loss of integrity was also observed in BS patients without neurological manifestations, albeit to a lesser extent. In NBS patients, certain white matter tracts, including cingulum bundle, were associated with poor cognitive performance across multiple domains and disease severity. DISCUSSION: DTI findings might potentially serve as a neuroimaging marker to predict the extent of neurocognitive impairment and disease severity associated with central nervous system involvement in BS.

Carotid artery ultrasonography and shear wave elastography in Takayasu's arteritis: a comparative analysis with diabetes mellitus.

OBJECTIVES: Takayasu's arteritis (TAK) is a chronic inflammatory large vessel vasculitis with a grim prognosis due to the excessive risk for cardiovascular (CV) diseases. Its diagnosis relies on radiographic imaging and its differentiation particularly from atherosclerosis could be challenging. Hypothesising that vascular morphology observed in TAK would be comparable to that found in type 2 diabetes mellitus (T2DM), a prototype for advanced atherosclerosis, we compared two disease groups using carotid artery B mode US and shear wave elastography (SWE). METHODS: A total of 72 patients with TAK (63F/9M; mean age: 42.7± 10.0 years) and 74 patients with T2DM (65F/9M; mean age: 50.2± 7.1 years) were studied. Intima-media thickness (IMT), outer diameter and arterial stiffness as assessed by SWE values were measured on the common carotid artery (CCA) and atherosclerotic plaques were recorded. Clinical characteristics, CV risk factors and previous history of CV diseases were determined. Framingham risk score was calculated. RESUULTS: Patients with TAK exhibited significantly lower atherosclerotic risk but higher systolic blood pressure (BP) levels compared to those with T2DM. The mean values of CCA IMT, outer diameter, and stiffness were significantly elevated among patients with TAK compared to those with T2DM. Carotid artery plaques were evenly distributed between the study groups, but their anatomical localisation and composition differed significantly. While coronary artery disease (CAD) was more prevalent among T2DM patients, cerebrovascular diseases were more frequent among TAK patients. CONCLUSIONS: Our study revealed distinctive vascular alterations and atherosclerotic changes when compared to advanced atherosclerosis associated with T2DM. Apart from these, higher levels of systolic BP and significantly different distribution of CV diseases between TAK and T2DM also suggest that TAK should be handled with distinct assessment strategies than that employed in conventional atherosclerotic conditions.

Atrial myxoma as a mimicker of intracardiac thrombus in Behçet's syndrome: a case study with histopathological confirmation.

Cardiomyopathies cause most intracardiac thrombosis (ICT), and Behçet's syndrome (BS) is a rare inflammatory disease that can be responsible for a proportion of ICT. Other inflammatory disorders involved in the aetiology of ICT include antiphospholipid syndrome, Henoch-Schonlein purpura, COVID-19, and Loeffler endocarditis. ICT usually occur during the active phase of BS, and they have a close relationship with vascular involvement. Atrial myxomas are benign cardiac tumours arising from the interatrial septum. They can lead to a substantial acute phase response, making them difficult to distinguish from inflammatory diseases. In this case study, we present a 46-year-old female BS patient who presented with constitutional symptoms mimicking BS flare in a routine follow-up visit and was diagnosed with left atrial myxoma after administration of several lines of immunosuppressives. Then, she underwent surgical tumour excision, and a histopathological examination confirmed the diagnosis.In conclusion, atrial myxoma should be kept in mind first of all when suspecting ICT, and advanced imaging methods such as cardiac magnetic resonance imaging (MRI) should be used if necessary.

Tocilizumab may not be a good option for vascular involvement due to Behçet's syndrome.

OBJECTIVES: Tocilizumab has been increasingly reported as an alternative therapeutic agent in the management of Behçet's syndrome (BS) and it has been mostly tried in BS patients with neurological and eye involvement. As therapeutic responses to each drug may vary across different types of BS involvement, we aimed to report seven patients with large vessel involvement treated with tocilizumab. METHODS: We enrolled seven BS patients with vascular involvement who were given tocilizumab at the Behçet's Disease Research Centre in Istanbul University-Cerrahpasa between 2000 and 2022. Demographic information, BS features, types of vascular involvement, previous and concomitant medications, C-reactive protein (CRP) levels, imaging modality results, and outcomes were documented from the patients' medical records. RESULTS: Within a median of 6 months after the initiation of tocilizumab, 5 patients experienced vascular relapses. These relapses included the emergence of new bilateral pulmonary artery aneurysms, a new pulmonary artery thrombus, parenchymal lung involvement, deep vein thrombosis in the lower extremity, and pseudotumor cerebri in one patient each. CRP levels were normal in 4 of the 5 patients at the time of vascular relapse. One of these 5 patients and another patient with aortitis had an exacerbation of mucocutaneous symptoms. In the last patient, venous ulcers did not respond to tocilizumab and were complicated with infection. CONCLUSIONS: Tocilizumab could potentially exacerbate vascular manifestations, similar to what is observed with mucocutaneous lesions in BS patients. Furthermore, CRP levels appear to be ineffective in monitoring these patients.

Role of Optical Coherence Tomography in Vasculitis-Associated Pulmonary Hypertension and Chronic Thromboembolic Pulmonary Hypertension.

BACKGROUND: Identifying and understanding the microstructural changes within the wall of the pulmonary artery (PA) is crucial for elucidating disease mechanisms and guiding treatment strategies. We assessed the utility of optical coherence tomography (OCT) in identifying such changes within segmental/subsegmental PAs and compared the morphological variations in WHO group 4 pulmonary hypertension associated with Behcet Disease (BD), Takayasu arteritis (TA) and chronic thromboembolic pulmonary hypertension (CTEPH). Idiopathic pulmonary arterial hypertension (IPAH) patients served as controls.Methods and Results: A total of 197 cross-sectional images were analyzed from 20 consecutive patients. BD patients exhibited lower %wall area and mean wall thickness (MWT) compared with CTEPH, TA and, IPAH patients. TA patients showed a notably higher %wall area, which was significant in IPAH and BD patients. Variations in %wall area measurements were observed across distinct cross-sectional segments of the PA within individual patients (22% in CTEPH, 19% in BD, 16% in TA, 23% in IPAH patients). Intravascular webs, bands, and thrombi were observed in BD and CTEPH patients. OCT provided clear delineation of vascular wall calcifications and adventitial vasa vasorum. No procedure-related complications were observed. CONCLUSIONS: PA involvement differs among the various etiologies of PH, with the PA being heterogeneously affected. OCT offers promise in elucidating microstructural vascular wall changes and providing insights into disease mechanisms and treatment effects.

A Proposal of a New Tool for the Assessment of Damage in Behçet Syndrome Uveitis: Cerrahpasa Ocular Damage Grading System.

INTRODUCTION/OBJECTIVE: There is currently no tool available to assess the severity of damage in uveitis due to Behçet's syndrome (BS). In this preliminary study, we developed a new grading system to evaluate ocular damage and assessed it in a prospective cohort. METHODS: A specialist in BS uveitis (YO) developed a grading system for ocular damage with five grades based on the extent of damage in the posterior segment. YO trained a senior and general ophthalmologist with sample fundus images. BS patients who had undergone color fundus photography during their routine visits in attack-free periods were included in the study. The color fundus photos of this prospective cohort were evaluated blindly by YO and his trainees using the new grading tool. Inter and intra-observer agreement between the graders were assessed by Cohen's kappa analysis. The evaluation of YO was considered as the gold standard. RESULTS: One hundred eighty-five eyes of 108 (29 F/79 M) patients with BS uveitis were graded for damage by two investigators. Their mean age was 38,58 years and their median ocular disease duration was 13 years. The gold standard and the two investigators exhibited substantial concordance with the ocular damage grading system. The inter- and intra-observer agreement were also almost perfect. CONCLUSION: The newly developed ocular damage grading system enables the standardization of damage severity in BS uveitis. It is imperative to conduct internal and external validations across diverse cohorts. Furthermore, future studies should investigate its correlation with other multimodal imaging methods such as fluorescein angiography and optical coherence tomography.

Hearing loss in Takayasu's arteritis.

OBJECTIVES: Neurosensory hearing loss is well-documented in chronic autoimmune conditions such as systemic lupus erythematosus (SLE). However, the literature lacks data on the prevalence and characteristics of hearing impairment in Takayasu's arteritis (TAK). In this cross-sectional study, our principal objective was to systematically assess the auditory function of individuals diagnosed with TAK, against SLE patients and healthy controls (HC). METHODS: Age and gender matched TAK and SLE patients followed up in a tertiary centre along with healthy controls were included in a two-phase study. In the first phase, a questionnaire on ENT symptoms was administered to the patient (TAK: n=104 and SLE: n= 151) and HC (n=174) groups. In the second phase, patients (TAK: n=53 and SLE: n=33) and HC (n=45) underwent audiometric tests. RESULTS: The questionnaire survey revealed that both TAK and SLE patients reported hearing loss (27.9%, 25.8%, 7.4%, p<0.001), tinnitus (49%, 35.8%, 13.8%, p<0.001) and vertigo (46.2%, 33.8%, 16.7%, p<0.001) at significantly higher rates than HC. Audiometry results indicated that both TAK (30.2%) and SLE patients (18.2%) had increased hearing loss compared to HC (8.9%), however, only TAK patients were found to have significantly increased risk in age adjusted logistic regression analysis (OR= 3.915, 95%CI: 1.179-12.998, p=0.026). Hearing loss was mainly neurosensory in all groups. TAK patients were affected at both low (<6000 Hz) and high (>6000 Hz) frequencies, whereas SLE patients were affected only at high frequencies. Hearing loss was significantly associated only with older age. No association was observed with the anatomical location of vascular involvement or history of stroke. CONCLUSIONS: Our study reveals an increased prevalence of hearing loss in TAK. Further research is crucial to uncover the underlying causes.

Folliculitis might be associated with pathergy-positivity in patients with Behçet syndrome.

Pathergy test indicates nonspecific hyper-reactivity of the skin to aseptic trauma in Behçet syndrome (BS) and is considered as an adjunctive diagnostic test with a good specificity albeit with low sensitivity. We tested the hypothesis that a relationship exists between active clinical manifestations of BS and the pathergy-positivity when performed simultaneously. Pathergy test and detailed dermatologic examination were done in 105 BS patients (60M/45F); who were seen consecutively at the multi-disciplinary BS outpatient clinic in a single tertiary center. Information regarding demographic and clinical characteristics, pathergy test results at diagnosis, and details about treatment were obtained from patient charts. Disease activity was assessed using Behçet Disease Current Activity Form. Among 105 patients, 27 (25.7%) were pathergy-positive at the time of the study visit whereas 40.9% were pathergy-positive at the time of the diagnosis. There was no relation between pathergy test and patient age or disease duration, either. Pathergy-positivity was significantly more common in patients with folliculitis compared to those without folliculitis (40.7% vs 19.2%; P = .026). The test was also positive in all 3 patients with leg ulcers due to venous stasis. We found that among all skin-mucosa lesions only the presence of folliculitis was associated with pathergy positivity with statistical significance. It was also remarkable that the current pathergy was positive in all 3 patients with active leg ulcers but this finding warrants further studies because of the low patient numbers.

HLA-B gene methylation and expression in Behçet's syndrome: a potential role of epigenetics in the pathogenesis.

OBJECTIVES: The HLA-B51 locus has the strongest association with Behçet's syndrome (BS). The presence of a CpG island in the HLA-B gene led us to examine the role of epigenetic regulation in BS. METHODS: HLA-B51 genotyping was performed via sequence-specific PCR in 15 index familial BS cases, 17 affected relatives, 26 unaffected relatives, 46 sporadic BS cases, and 41 healthy controls. HLA-B methylation level was determined using the Zymo OneStep qMethyl kit, and HLA-B51 mRNA level was assessed by quantitative real-time PCR in 14 index familial BS cases, 15 affected relatives, 15 unaffected relatives, 11 sporadic BS cases, and 10 healthy controls. RESULTS: HLA-B51 carrier ratio was 13/15 in index familial cases, 13/17 in affected relatives, 22/26 in unaffected relatives, 8/25 in healthy controls, and 35/47 in sporadic BS cases. HLA-B51 expression level in HLA-B51+ BS cases was 2.2-fold higher than in their unaffected relatives (p=0.0149) and 1.3-fold higher than in healthy controls (p=0.0188), while sporadic BS cases had a 2.7-fold higher level than healthy controls (p=0.0487). HLA-B promoter methylation was significantly lower in HLA-B51+ familial BS cases than in unaffected relatives (0.4-fold, p=0.01), affected relatives (0.36-fold, p=0.0219), and healthy controls (0.34-fold, p=0.0371) and slightly lower in HLA-B51+ sporadic BS cases than in healthy controls (0.71-fold, p=0.2347). There was an inverse correlation between HLA-B promoter methylation and HLA-B51 expression in HLA-B51+ sporadic BS cases (p=0.0164). CONCLUSIONS: This study indicates epigenetic involvement associated with the HLA-B51 locus in BS, both in familial and sporadic cases. Further studies with larger sample sizes are needed to confirm our results.

Pulmonary artery involvement due to Behçet's syndrome and Hughes Stovin syndrome: a comparative study.

OBJECTIVES: Hughes-Stovin syndrome (HSS) is a rare inflammatory condition defined as pulmonary artery aneurysms (PAA) associated with deep vein thrombosis. It is similar to vascular involvement of Behçet's syndrome (BS), but differs in the absence of typical skin-mucosal findings. Whether HSS is a distinct entity or a form fruste of BS is debated. We formally compared HSS cases retrieved from the literature to BS patients with PAI followed by a tertiary centre. METHODS: A systemic literature search using 'Hughes Stovin syndrome' as the key word covering the period between 2000 and 2023 revealed 58 (43 M/15 F) case reports (PROSPERO: CRD42023413537). We identified 74 (62M/12 F) BS patients with PAI followed up in a tertiary centre in Turkey from 2000 until 2020. We evaluated two cohorts head-to-head in terms of demographic and clinical features. RESULTS: BS and HSS patients were found to be comparable with regard to several demographic, clinical and histopathological features. However, PAA were significantly more frequent and isolated pulmonary artery thrombosis (PAT) less common in HSS than that found in BS. Moreover, patients with HSS were more likely to be treated with anti-coagulants and vascular or surgical interventions, whereas less likely to receive immunosuppressive treatment. CONCLUSIONS: Our study indicates that HSS is indeed an 'incomplete form of BS'. It can be considered as evidence supporting the notion that the vascular phenotype develops independently from skin-mucosa lesions and uveitis in BS. However, HSS has been described mainly focusing on aneurysms, overlooking the aspect of in-situ thrombosis.

Abdominal aortic aneurysm healed with calcification in a female patient with Behçet's syndrome: A case report with a 2-decade follow-up.

Abdominal aortic aneurysms (AAA) are rare in Behçet syndrome (BS) but may result in life-threatening complications. AAA are generally treated with surgical intervention following aggressive immunosuppressive therapy. Healing with wall calcification and mural thrombus for AAA is scarcely reported in the literature. Herein, we present a female patient who developed a large saccular aneurysm in the infra-renal abdominal aorta 6 months after the diagnosis. Endovascular intervention was not found to be possible because of the dimensions of the aneurysm and the patient did not consent for open surgery. Therefore, she received only immunosuppressive treatment. By the second year of follow-up, we detected reduction in the size of AAA, along with circumferential wall calcification and mural thrombus. The patient was followed-up for 20 years without rupture and currently doing well. This case demonstrates that calcified large saccular AAA might not necessitate surgical intervention and be followed-up for many years without any complication.

Behçet's syndrome: one year in review 2023.

This critical review of studies on Behçet's syndrome published during 2022 includes studies on epidemiology, patients' perspective, pathogenesis, diagnosis, clinical features and management. Studies on pathogenesis included potential biomarkers mostly related to macrophages, neutrophil and cytokine balance, new GWAS and polymorphism studies, and studies on miRNAs and long non-coding RNAs. Clinical studies showed that application of pneumococcal vaccine to the prick site increased the sensitivity and specificity of the pathergy test and the prevalence of AA amyloidosis had decreased over the years. Studies on management indicated that more data are needed to understand the effect of apremilast on BS manifestations other than oral ulcers, and new BS manifestations may develop during treatment with infliximab. Other biologics and Jak inhibitors might be an option for patients who are refractory to TNF-α inhibitors. Moreover, endovascular repair of arterial aneurysms might be an alternative to open surgery.

Mycophenolate mofetil may be an alternative for maintenance therapy of Behçet syndrome uveitis: a single-center retrospective analysis.

Experience with mycophenolate in uveitis due to Behçet syndrome (BS) is limited. Twelve patients with panuveitis or posterior uveitis who were started mycophenolate were included. Data on demographic characteristics, therapies, ocular attacks, and adverse events were extracted from patient charts. Seven patients with BS uveitis were prescribed mycophenolate for remission induction, of which 6 were refractory/intolerant to conventional immunosuppressives. Mycophenolate was combined with anti-TNFs in 3 patients, resulting in no further ocular attacks. Mycophenolate had to be stopped in the fourth patient due to adverse events. The remaining 3 patients continued to have ocular attacks and were switched to other agents without any drop in visual acuity. Among the 5 patients who were prescribed mycophenolate for maintenance, 2 were relapse free, but 3 experienced ocular attacks. One patient had an exacerbation of mucocutaneous lesions, and 2 experienced adverse events. Mycophenolate monotherapy may not be adequate for remission induction of refractory BS uveitis, but it can be a safe and effective alternative when combined with a biologic agent. It may also be an option for maintenance therapy.

Behçet disease, familial Mediterranean fever and MEFV variations: More than just an association.

Behçet disease (BD) and familial Mediterranean fever (FMF) are two inflammatory disorders that share many features including historical background, ethnical distribution and inflammatory characteristics. Several studies suggested that BD and FMF might occur in the same individual more commonly than expected. Additionally, the pathogenic MEFV gene variants, especially p.Met694Val, activating the inflammasome complex have been shown to increase the risk for BD in regions where both FMF and BD are prevalent. Whether these variants are associated with certain disease subtypes and whether they may help in the planning of treatment need to be explored. This review provides a recent overview of the plausible association between FMF and BD and the role of MEFV variants in the pathogenesis of BD.

Increased arterial stiffness and accelerated atherosclerosis in Takayasu arteritis.

INTRODUCTION: Cardiovascular diseases are the leading causes of morbidity and mortality in patients with Takayasu arteritis (TAK). Arterial stiffness and accelerated atherosclerosis have been reported in TAK, however, morphological changes in the arterial wall have not been adequately addressed. Shear wave elastography (SWE) is a new, non-invasive, direct and quantitative method of ultrasonography (US) that evaluates elasticity of biological tissues. METHODS: A total of 50 patients with TAK (44F/6 M; mean age: 39.8 ± 8.2 years), 43 with systemic lupus erythematosus (SLE) (38F/5 M; 38.0 ± 7.9 years) and 57 healthy controls (HCs) (50F/7M: 39.5 ± 7.1 years) were studied using carotid B mode US and SWE. Carotid artery intima-media thickness (CCA IMT) and SWE were measured and the atherosclerotic plaques were recorded. Clinical characteristics and cardiovascular risk factors were determined. Intra and inter observer reproducibility was assessed and found good agreement. RESULTS: The mean IMT in the right and left carotid arteries was significantly higher only among patients with TAK when compared to SLE and HCs. Carotid artery plaques were significantly increased only in patients with TAK. On the other hand, the mean SWE value was significantly increased among both TAK and SLE patients when compared to HCs, whereas patients with TAK had the highest value. These were also true after adjustments were made for atherosclerotic risk factors and after all those with atherosclerotic plaques were excluded from the analysis. TAK itself, diastolic blood pressure levels and IMT were independently associated with SWE. CONCLUSIONS: Markedly increased CCA IMT and SWE values appear to be uniquely associated with TAK, suggesting that they could be used as diagnostic tools. Arterial stiffness occurs independently from atherosclerosis and is associated with arterial thickening. Further studies should investigate whether CCA SWE values could predict cardiovascular morbidity and mortality. Strong association with premature atherosclerosis could be also considered as a unique feature of TAK.

Secukinumab-induced IgA vasculitis in a patient with psoriatic arthritis.

OBJECTIVES: Secukinumab (SEC) is an effective and widely used drug in psoriatic disease and axial spondyloarthritis. However, SEC has been found to be associated with inflammatory conditions and vasculitis. These inflammatory adverse effects may complicate the treatment of underlying disease, and clinicians may experience difficulties in recognizing and managing this unusual condition. CASE REPORT: A man aged 56 years with psoriatic disease refractory to conventional disease-modifying antirheumatic drugs was given adalimumab for 6 weeks, then switched to SEC when his psoriatic lesions were exacerbated. After 3 weeks of SEC treatment, he developed systemic features of IgA vasculitis while his skin lesions and arthritis persisted. CONCLUSIONS: Although SEC-related inflammatory adverse events, including vasculitis, are rarely encountered in clinical practice, it is essential to recognize them because they can be mistaken as a component of the underlying inflammatory disease. In addition, the dramatic improvement in many cases after the cessation of SEC underlines the importance of making an accurate diagnosis. Pathogenetically, these adverse events are likely to be paradoxical reactions, except for SEC-induced inflammatory bowel diseases. However, in many aspects, their pathogenesis is controversial and needs clarification.

Orbital Mass as the Only Presenting Sign with Overlapping Features of Lupus Erythematosus Panniculitis and Subcutaneous Panniculitis-Like T-Cell Lymphoma.

PURPOSE: Even though subcutaneous panniculitis-like T-cell lymphoma (SPTCL) and lupus erythematosus panniculitis (LEP) are two separate entities, recently they were claimed to represent two ends of a spectrum of T-cell-mediated orbital lymphoproliferative diseases. METHODS: A 78-year-old woman presented with a 1-month history of right-sided periorbital swelling and redness. There was a palpable mass in the medial right lower eyelid with restriction of upward and lateral gaze. MRI revealed a 14 × 7 mm hypointense lesion in the anteromedial orbit. RESULTS: The systemic and ocular findings, orbital biopsy with histopathology and immunochemistry showed overlapping features of LEP and SPTCL. The patient was consulted with rheumatology and hematology, and the physicians arrived at a consensus that the patient existed in the above-mentioned disease spectrum. She was started on systemic immunosuppressive treatment and her clinical findings improved substantially. CONCLUSIONS: This is the first report of a patient, who presented with orbital mass causing vision loss and gaze restriction that had overlapping clinical and histopathologic features of LEP and SPTCL consistent with this novel disease spectrum, in the literature.
