RESUMEN
OBJECTIVES: Vacuoles, E1 enzyme, X-linked, autoinflammatory and somatic (VEXAS) syndrome is an adult-onset autoinflammatory disease associated with somatic ubiquitin-like modifier-activating enzyme 1 (UBA1) mutations. We aimed to evaluate the efficacy and safety of targeted therapies. METHODS: Multicentre retrospective study including patients with genetically proven VEXAS syndrome who had received at least one targeted therapy. Complete response (CR) was defined by a clinical remission, C-reactive protein (CRP) ≤10 mg/L and a ≤10 mg/day of prednisone-equivalent therapy, and partial response (PR) was defined by a clinical remission and a 50% reduction in CRP levels and glucocorticoid dose. RESULTS: 110 patients (median age 71 (68-79) years) who received 194 targeted therapies were included: 78 (40%) received Janus kinase (JAK) inhibitors (JAKi), 51 (26%) interleukin (IL)-6 inhibitors, 33 (17%) IL-1 inhibitors, 20 (10%) tumour necrosis factor (TNFα) blockers and 12 (6%) other targeted therapies. At 3 months, the overall response (CR and PR) rate was 24% with JAKi, 32% with IL-6 inhibitors, 9% with anti-IL-1 and 0% with TNFα blockers or other targeted therapies. At 6 months, the overall response rate was 30% with JAKi and 26% with IL-6 inhibitors. Survival without treatment discontinuation was significantly longer with JAKi than with the other targeted therapies. Among patients who discontinued treatment, causes were primary failure, secondary failure, serious adverse event or death in 43%, 14%, 19% and 19%, respectively, with JAKi and 46%, 11%, 31% and 9%, respectively, with IL-6 inhibitors. CONCLUSIONS: This study shows the benefit of JAKi and IL-6 inhibitors, whereas other therapies have lower efficacy. These results need to be confirmed in prospective trials.
RESUMEN
INTRODUCTION: Idiopathic Multicentric Castleman Disease (iMCD) is a complex and poorly understood pathophysiological entity, which encompasses a variety of conditions and can mimic or be associated with autoimmune/autoinflammatory diseases, making it challenging to diagnose and treat. Vacuoles, Enzyme E1, X-linked, Autoinflammatory, Somatic (VEXAS) syndrome is an adult-onset autoinflammatory disorder associated with hematological abnormalities and caused by acquired somatic mutations in the ubiquitin-like modifier activating enzyme 1 gene (UBA1) which shares several common clinical and biological signs with iMCD. In this article, we report a patient with VEXAS syndrome initially presenting as iMCD, questioning the link between these two entities. CASE DESCRIPTION: We report here a patient initially presenting as iMCD, proved on lymph node histology, which turns out to have a mutation at the splice acceptor site of exon 3 of UBA1 exhibiting VEXAS syndrome with Castleman-like lymph node. CONCLUSION: This is only the second case of VEXAS syndrome presenting as iMCD. VEXAS syndrome should therefore be considered in the presence of iMCD suspicion, including in cases of compatible histology.

OBJECTIVES: To identify factors associated with the progression of giant cell arteritis (GCA)-related or associated aortic dilations. METHODS: In this retrospective study, 47 GCA patients with aortic dilation were longitudinally analyzed. Each patient underwent ≥2 imaging scans of the aorta during the follow-up. Three progression statuses of aortic dilations were distinguished: fast-progressive (FP) defined by a progression of the aortic diameter ≥5 mm/year or ≥1 cm/2 years, slow progressive (SP) by a progression of the aortic diameter >1 mm during the follow-up, and not progressive (NP) when aortic diameter remained stable. RESULTS: Among the 47 patients with aortic dilation, the thoracic section was involved in 87 % of patients. Within a total follow-up of 89 [6-272] months, we identified 13 (28 %) patients with FP dilations, and 16 (34 %) and 18 (38 %) patients with SP and NP dilations, respectively. No differences regarding baseline characteristics, cardiovascular risk factors or treatments were observed among the 3 groups. However, FP patients more frequently showed atheromatous disease (p = 0.04), with a more frequent use of statins (p = 0.04) and antiplatelet agents (p = 0.02). Among the 27 (57 %) patients with aortitis, aortic dilation developed on an inflammatory segment in 23 (85 %). Among the FP patients who underwent aortic surgery with available histology (n = 3), all presented active vasculitis. CONCLUSION: This study suggests that aortic inflammation, as well as atheromatous disease, might participate in the fast progression of aortic dilation in GCA.
RESUMEN
OBJECTIVES: To analyse in routine practice the efficacy of targeted therapies on joint involvement of patients with rheumatoid arthritis/systemic sclerosis (RA/SSc) overlap syndrome. METHODS: This was a retrospective analysis of medical records of two academic centres over a 10-year period. Joint response to targeted therapies was measured according to EULAR criteria based on Disease Activity Score (DAS)-28. In addition, changes in CRP level and glucocorticoid consumption were recorded. RESULTS: Nineteen patients were included. Methotrexate (n=11) and hydroxychloroquine (n=4) were the most used first-line treatments. Targeted therapies were frequently used (n=14). Tocilizumab was the most selected therapy (n=8), then rituximab (n=5), abatacept and anti-tumour necrosis factor (n=4). Twenty-one treatment sequences were assessed, including 18 with EULAR response criteria. Responses were "good" or "moderate" in 100% (4/4) of patients treated with abatacept, 80% (4/5) with rituximab, 40% (2/5) with tocilizumab, and 25% (1/4) with anti-TNF. T and B lymphocyte-targeted therapies (abatacept, rituximab) resulted more frequently in a "good" or "moderate" response compared to cytokine inhibitors (tocilizumab, etanercept, infliximab) with a significant decrease in DAS-28 at 6 months (-1.75; p=0.016) and a trend to a lower consumption of glucocorticoids. CONCLUSIONS: In patients with RA/SSc overlap syndrome refractory to conventional synthetic-DMARDs, T and B lymphocyte-targeted therapies seem to be a promising therapeutic option to control joint activity.

OBJECTIVES: To assess the frequency and characteristics of severe relapse in patients with giant cell arteritis (GCA) in a real-life setting. METHODS: In a monocentric database of 530 patients, we retrospectively analysed patients who experienced at least one relapse and distinguished severe from nonsevere relapses. Severe relapse was defined by the occurrence of an ischaemic event (ophthalmologic, neurologic, digestive, limb ischaemia), the occurrence of an aortic complication (i.e. new or worsening of aortic dilation, aortic dissection), or new or worsening of vascular stenosis. RESULTS: From the cohort of 530 patients, 242 (45.7%) patients experienced relapse at least once, including 13 (2.5% of the cohort) who experienced severe relapse. Among the 464 recorded relapses, 14 (3% of all relapses) were severe. Severe relapse corresponded to the following vascular events: a peripheral limb ischaemia in 6 patients, a visual event in 3 patients (including 2 acute anterior ischaemic anterior neuropathies), an aortic complication in 3 patients, a mesenteric ischaemia in one patient and an ischaemic stroke in one patient.When compared with the 229 patients who experienced nonsevere relapses, severe relapse patients were younger at diagnosis (p= 0.02), more frequently showed limb claudication at baseline (p< 0.0001) and fewer GCA-related cranial signs (p< 0.0001). At diagnosis, more large-vessel vasculitis on imaging (82% vs 36%, p= 0.002) were observed in patients with severe relapse. The death rate did not differ between patients with severe and nonsevere relapses. CONCLUSION: In a real-life setting, relapse affects nearly half of GCA patients, but severe relapse is rare.
RESUMEN
Objectives: To determine how therapeutic strategies for giant cell arteritis (GCA), especially glucocorticoid (GC) management, evolved between 2014 and 2020. Patients and Methods: Consecutive GCA patients followed for at least 24 months in a single tertiary center were enrolled and separated into two groups: those diagnosed from 2014 to 2017 and those diagnosed from 2018 to 2020. GC doses (mg/kg/day) were analyzed at onset, at Month 3 (M3) and, if continued, at M6, M12, M18 and M24. Physicians' practices were also individually analyzed. Results: Among the 180 patients included, 96 (53%) were diagnosed in 2014-2017 and 84 (47%) in 2018-2020. All patients received GC at diagnosis without a difference in the initial dose between the two groups (p = 0.07). At M3, the daily dose was lower in patients treated after 2017 (p = 0.002). In patients who still received GC at M6 (p = 0.0008), M12 (p = 0.01) and M24 (p = 0.02), the daily GC dose was still lower in patients treated after 2017. The proportion of patients who definitively discontinued GC use before M18 (42% versus 21%, p = 0.003) was higher in those treated after 2017. The rates of immunosuppressant use were not different between the two time periods (31% versus 38%, p = 0.34), but tocilizumab replaced methotrexate. Significant differences were observed among practitioners regarding the GC doses at M6 (p = 0.04) and M12 (p = 0.04), the total GC duration (p = 0.02) and the ability to stop GC before M18 (p = 0.007). Conclusions: This real-life study showed a global change in GC management over time for GCA patients, with important variability among physicians' practices.
RESUMEN
OBJECTIVES: To assess the indications, efficiency and tolerance profiles of methotrexate (MTX) in patients with giant cell arteritis (GCA) in a real-life setting. METHODS: From a monocentric database of >500 GCA patients, we retrospectively selected 49 patients who received MTX between 2010 and 2020. Cumulative glucocorticoid (GC) doses, the number of relapses and GC-related adverse events were recorded before, during and after MTX. We separately analyzed the 3 main indications of MTX, i.e., disease relapse, GC-sparing strategy, and GCA presentation. RESULTS: With a median follow-up of 84 [10-255] months, 25 (51%) and 18/41 (44%) patients relapsed during MTX treatment and after its discontinuation, respectively. Among the 40 patients who relapsed before MTX, 26 (65%) experienced a new relapse after MTX introduction. Once MTX was introduced, 24 (49%) patients were able to discontinue GC after 20.5 [7-64] months. No significant difference in cumulative GC doses were noted before and after MTX introduction with a total GC dose of 14.7 [1.05-69.4] grams. At the last follow-up, MTX was discontinued in 41 patients, including 13 (32%) due to clinicobiological remission, 12 (30%) due to treatment failure and 15 (36%) due to side effects. CONCLUSION: Our real-life study showed a modest beneficial effect of MTX on relapse in patients with GCA. However, we did not observe any GC-sparing effect in this study. Other studies are needed to assess the GC-sparing effect in patients in whom GC management is adapted from recent recommendations.

Introduction: This study aimed to provide an updated analysis of the different prognostic trajectories of patients with anti-melanoma differentiation-associated gene 5 (MDA5) antibodies. Methods: Among a cohort of 70 patients, baseline characteristics and phenotypes, treatments and outcomes were analyzed. A Cox proportional hazards model was used to identify factors associated with poor outcomes, i.e., death or progressive disease at the last follow-up. Results: Among the 70 patients, 45 were women, and 54 were Caucasian. A dermatologic involvement was observed in 58 (83%) patients, including 40 with MDA5 vasculopathy-related skin lesions. Muscular involvement was observed in 39 (56%) patients. Interstitial lung disease (ILD) was observed at baseline in 52 (74%) patients, including 23 (44%) who developed rapidly progressive (RP) ILD. Seven (10%) patients showed thromboembolic complications within the first weeks of diagnosis, and eight (11%) other patients developed a malignancy (4 before the diagnosis of anti-MDA5 disease). Poor outcomes were observed in 28 (40%) patients, including 13 (19%) deaths. Among the 23 patients with RP-ILD, 19 (79%) showed poor outcomes, including 12 (63%) who died. In multivariate analyses, RP-ILD (hazard ratio (HR), 95% CI: 8.24 [3.21-22], p<0.0001), the occurrence of thromboembolic events (HR: 5.22 [1.61-14.77], p=0.008) and the presence of any malignancy (HR: 19.73 [6.67-60], p<0.0001) were the three factors independently associated with poor outcomes. Discussion: This new independent cohort confirms the presence of different clinical phenotypes of anti-MDA5 diseases at baseline and the poor prognosis associated with RP-ILD. Thromboembolic events and malignancies were also identified as prognostic factors.

OBJECTIVES: To analyze whether beta-blockers (BBs), in addition to conventional care, can decrease the risk of aortic dilation in giant-cell arteritis (GCA)-related aortitis. METHODS: We conducted in a single medical center retrospective study including 65 consecutive patients with GCA-related aortitis who all underwent aortic morphology control during follow-up. The impact of previous cardiovascular (CV) risk factors and/or events on BB prescription and on the risk for new aortic dilation was analyzed using a weighted (8-point maximum) score between 0 (i.e., 0/8 CV risk factors and events) and 1 (i.e., 8/8). RESULTS: Among the 65 patients with GCA-related aortitis, 15 (23%) were taking BBs before GCA diagnosis and continued them thereafter. The vascular score was significantly higher in patients who received BBs (0.25 [0.125-0.625] vs. 0.125 [0-0.625] in patients without BBs, p < 0.0001). The median follow-up was 91 [25-163] months in GCA patients taking BBs and 61 [14-248] months in patients not taking BBs (p = 0.13). None of the patients taking BBs developed a new aortic dilation, whereas 15 (15/50; 30%) patients not taking BBs did (p = 0.01), as detected at a median time of 38 [6-120] months after the first imaging. Rates of other CV events during follow-up did not differ between the groups (p = 1). CONCLUSIONS: This study is the first to suggest that BBs in addition to conventional care in patients with GCA-related aortitis may help to prevent the risk of aortic dilation during follow-up. Larger-sized studies are required to confirm these results.

OBJECTIVE: A new adult-onset autoinflammatory syndrome has been described, named VEXAS (Vacuoles, E1 Enzyme, X-linked, Autoinflammatory, Somatic). We aimed to compare the clinical characteristics, the laboratory features and the outcomes between idiopathic-relapsing polychondritis (I-RP) and VEXAS-relapsing polychondritis (VEXAS-RP). METHODS: Patients from French retrospective multicentre cohort of RP were separated into two groups: a VEXAS-RP and an I-RP. RESULTS: Compared with patients with I-RP (n=40), patients with VEXAS-RP (n=55) were men (96% vs 30%, p<0.001) and were older at diagnosis (66 vs 44 years, p<0.001). They had a greater prevalence of fever (60% vs 10%, p<0.001), of skin lesions (82% vs 20%, p<0.001), of ocular involvement (57% vs 28%, p=0.01), of pulmonary infiltrates (46% vs 0%, p<0.001), of heart involvement (11% vs 0%, p=0.0336) and with higher median C-reactive protein levels (64 mg/L vs 10 mg/L, p<0.001). Seventy-five per cent of the patients with VEXAS-RP had myelodysplastic syndrome (MDS) versus none in I-RP group. The glucocorticoids use, and the number of steroid sparing agents were similar in both groups, but patients with VEXAS-RP had more frequent refractory disease (remission obtained in 27% vs 90%, p<0001). VEXAS-RP was associated with higher risk of death: six patients (11%) died in the VEXAS-RP group after a median follow-up of 37 months and none in the I-RP group after a median follow-up of 92 months (p<0.05). CONCLUSION: We report the largest cohort of VEXAS-RP, characterised by high prevalence of male sex, fever, skin lesion, ocular involvement, pulmonary infiltration, heart involvement, older age and MDS association.

OBJECTIVE: The pathophysiological mechanisms involved in systemic sclerosis (SSc), especially the triggering factor, are poorly understood. The literature supporting the role of drugs in the onset of SSc primarily relies on case reports, short series or previous studies of old drugs. We aimed to update the list of suspected drugs associated with SSc (DASSc). METHODS: Analyzing the World Health Organization (WHO) pharmacovigilance database (Vigibase®), we collected all individual case safety reports (ICSRs) of drugs putatively associated with SSc reported since 1967 using the Medical Dictionary for Regulatory Activities preferred terms "systemic sclerosis" and "scleroderma". For each drug, a disproportionality analysis was performed by calculating the information component (IC). An identified drug was considered significant if the IC025 was >0. RESULTS: A total of 2800 deduplicated ICSRs of DASSc were identified, accounting for 509 ICSRs and 38 suspected DASSc after exclusion of protopathic and indication biases. Anticancer drugs were the most represented drug class, accounting for 16/38 (42%) of DASSc and 317/509 (62.3%) of ICSRs, which occurred mostly in the first years after the introduction of the drugs. Among these, taxane-based agents, bleomycin, vinblastine, imatinib, dacarbazine, pembrolizumab and pemetrexed were associated with the highest disproportionate reporting. Hormone replacement therapy, romiplostim and eculizumab were associated with a significant signal. DASSc was considered a serious adverse drug reaction in 404 (92%, n = 441) cases with 41 (9%) cases resulting in death. CONCLUSION: Several new drugs with significant disproportionality signals were identified as potential drugs implicated the development of SSc, particularly anticancer drugs.

OBJECTIVES: To describe the impact of cumulative glucocorticoid (GC) doses on related adverse events (AEs) in giant cell arteritis (GCA) in a real-life setting. METHODS: The medical charts of the last 139 consecutive GCA patients followed in a tertiary centre were retrospectively analysed. The cumulative GC doses were calculated, and the main GC-related AEs were collected during the follow-up. RESULTS: After a median follow-up duration of 35.6 (2-111) months, the median cumulative GC dose in the 139 patients was 9184 (1770-24,640) mg, and 131 patients (94%) presented at least one GC-related AE. Infections (63%) were the most frequently reported GC-related AE, followed by metabolic events (63%), including weight gain in 51% of them. Cardiovascular and neuropsychiatric events occurred in 51% and 47% of patients, respectively. Osteoporotic fractures, muscular involvement, digestive events, geriatric deterioration, skin fragility, ophthalmologic complications and hypokalaemia were reported in <35% of patients. Cardiovascular events (p = 0.01), osteoporotic fractures (p = 0.004), cataract occurrence (p = 0.03), weight gain (p = 0.04) and infections (p = 0.01) were significantly associated with GC cumulative doses > 9 g. Longer GC durations were associated with cataract occurrence (p = 0.01), weight gain (p = 0.03) and all-grade infections (p = 0.048), especially herpes zoster occurrence (p = 0.003). Neuropsychiatric and metabolic events appeared within the first months after GC introduction, whereas herpes zoster recurred, and most cardiovascular AEs emerged after 1 year. Geriatric events, especially osteoporotic fractures, occurred 2 years after GC introduction. CONCLUSION: This study highlights how frequent GC-related AEs are and the impact of prolonged GC and cumulative doses.
RESUMEN
OBJECTIVE: To assess patients' self-reported glucocorticoid (GC)-related adverse events (AEs) in a GCA population. METHODS: A questionnaire was sent to the 100 patients most recently diagnosed with GCA in a tertiary centre. This questionnaire included open- and close-ended questions on the disease and GC effects. Eight primary AE areas were analysed: cardiovascular, metabolic, muscle, cognitive and psychologic, bone, cutaneous and hairiness, infective and visual complications. Including derivative subitems from preceding areas, a total of 18 GC-related AEs were analysed separately and according to GC duration. RESULTS: Ninety patients were analysed and 89 (99%) reported at least one GC-related AE [median 6 (range 1-11)]. Cognitive and psychological changes, primarily insomnia (72%), affected 90% of patients. Cutaneous changes and muscle loss affected 70% of patients, with frequent impairment of physical autonomy (P = 0.007) associated with this event. Metabolic issues, especially weight gain (40%) and diabetes mellitus (20%), affected 49% of patients. Conversely, vision troubles and bone fractures were mentioned by 42% and 9% of patients, respectively, and more frequently in patients who received GCs for >18 months (P = 0.01 and P = 0.007, respectively). Cardiovascular changes and infections affected 30% and 26% of patients, respectively. CONCLUSION: This real-life study of GC tolerance assessed using a self-evaluation provides pragmatic and updated data reminding us that GC tolerance remains more noteworthy than ever. This study suggests carefully monitoring GC-related AEs during follow-up and encourages GC-sparing strategies in some patients.

OBJECTIVE: The literature supporting the role of a specific drug in the onset of drug-induced antineutrophil cytoplasmic antibody-associated vasculitis (AAV) mainly relies on case reports or short series and implicates old treatments. The advent of new treatments may have modified the epidemiology of these adverse drug reactions. This study was undertaken to update the list of drugs associated with AAV by using a pharmacovigilance-based data mining approach. METHODS: We collected data on adverse drug reactions reported using the Medical Dictionary for Regulatory Activities preferred term "anti-neutrophil cytoplasmic antibody positive vasculitis" up to November 2020 from the World Health Organization pharmacovigilance database (VigiBase). For each retrieved drug, a case-noncase analysis was performed, and disproportionate reporting was calculated by using the information component (IC). A positive IC025 value, which is the lower end of the 95% credibility interval, was considered significant. RESULTS: A total of 483 deduplicated individual case safety reports of drug-induced AAV involving 15 drugs with an IC025 >0 were retrieved. Of the individuals with drug-induced AAV for whom data on sex were available (n = 371), 264 (71.2%) were women. The median age at onset of drug-induced AAV was 62 years (quartile 1 [Q1]-Q3 45-72 years), and the median time from the introduction of the suspected drug to the onset of drug-induced AAV was 9 months (Q1-Q3 1-36 months). Drug-induced AAV was considered serious in 472 (98.1%), and was fatal in 43 (8.9%), of 481 cases. The drugs associated with the highest disproportionate reporting were hydralazine, propylthiouracil, thiamazole, sofosbuvir, minocycline, carbimazole, mirabegron, and nintedanib. CONCLUSION: Our findings strengthen the evidence of an association of AAV with previously suspected drugs, but also identify 3 new drugs that may cause drug-induced AAV. Particular attention should be given to these drugs by prescribers and in experimental studies.

Little is known about the impact of giant cell arteritis (GCA) and its treatment on patient-reported physical, mental, and psychic quality of life (QoL). In this monocentric study, a questionnaire was sent to the 100 last patients diagnosed with GCA and followed-up in a single tertiary center. Their physical, mental and psychic status were self-assessed via close-ended questions, the 12-item short form survey (SF-12) and the 15-item geriatric depression scale (GDS). We aimed to identify parameters that were significantly associated with moderate-to-severe disability in both physical and mental domains. Ninety patients were analyzable. Moderate to severe physical disability was found in 41 (46%) patients. In multivariate analysis, walking difficulties (OR, 95% CI 8.42 [2.98-26.82], p <0.0001), muscle mass and strength reduction (OR, 95% CI 4.38 [1.37-16.31], p = 0.01) and age >80 (OR, 95% CI 4.21 [1.44-13.61], p = 0.008) were independent findings associated with moderate to severe physical disability. Moderate to severe mental disability was found in 30 (33%) patients. In multivariate analysis, depressive mood (OR, 95% CI 11.05 [3.78-37.11], p < 0.0001), felt adverse events attributable to glucocorticoids (OR, 95% CI 10.54 [1.65-213.1], p = 0.01) and use of immune-suppressants (OR, 95% CI 3.50 [1.14-11.87], p = 0.03) were independent findings associated with moderate to severe mental disability. There was a statistically significant negative correlation between GDS and the physical and/or mental disability scores (GDS and PCS-12: r = -0.33, p = 0.0013; GDS and MCS-12: r = -0.36, p = 0.0005). In conclusion, this study identified via a self-assessment of patients with GCA some medical and modifiable findings that significantly affect their physical and mental quality of life. A better knowledge of these factors may help improve the care of GCA patients.
RESUMEN
INTRODUCTION: Double-positive patients (DPP) exhibiting anti-glomerular basement membrane (GBM) and anti-neutrophil cytoplasmic antibodies (ANCAs) belong to an entity that is newly and poorly described, mainly in short series. We aimed to better characterize the epidemiological features, clinical presentation and therapeutic outcomes of these patients through a systematic review. METHODS: We performed a systematic review of English-, German-, Spanish- and French-written publications from February 1987 to March 2020 reporting cases of DPP using the following databases: PubMed, Scielo, ScienceDirect, Google Scholar, The Cochrane Library, Open Grey, The Grey Literature Report, Clinicaltrials.gov and International Clinical Trial Registry Platform of the World Health Organization. RESULTS: In total, 538 DPP were identified from 90 articles. Their clinical presentations were often severe, and the majority exhibited acute kidney failure (91.8%) with a median initial serum creatinine level of 873 µmol/L; 50.7% had alveolar haemorrhage. Other manifestations were present in 30.3% of DPP, mainly ear, nose, throat and articular manifestations. ANCAs were predominantly directed against MPO (n = 377/523; 72.1%) compared to PR3 (n = 107/523; 20.5%), with rare cases of triple positivity (n = 15/538; 2.9%). Although most patients received initial immunosuppressive therapy (n = 285/317; 89.9%), the one-year overall, renal and relapse-free survival rates were 64.8%, 38.7% and 71.1%, respectively. CONCLUSION: DPP are associated with the characteristics of two eponymous vasculitis types, responsible for a poor overall and renal prognosis. Thus, simultaneous testing of both antibodies and systematic renal biopsy should be recommended in every patient with rapidly progressive glomerulonephritis to recognize this difficult-to-treat and rare disease.

Our aim was to describe the main features of amyloid goiter in adults with amyloidosis secondary to familial Mediterranean fever. Therefore, we analyzed cases from a French cohort of familial Mediterranean fever patients with amyloidosis and from literature review. Forty-two cases were identified: 9 from the French cohort and 33 from literature review. Ninety percent of patients were on hemodialysis for renal amyloidosis before the development of goiter. The goiter grew up rapidly in 88% of cases; 75.6% of patients were euthyroid, 58% displayed dyspnea, and 44.8% dysphagia. Various features were seen on ultrasound, from diffuse to multinodular goiter. When it was performed, fine-needle aspiration biopsy almost always revealed amyloidosis. Thirty-one patients underwent thyroidectomy: to manage compressive symptoms (72%) or rule out malignancy (27%). Histology showed mature adipose tissue in 64% of cases and lymphocytic infiltration in 21.4%. In conclusion, amyloid goiter in familial Mediterranean fever preferentially occurs in patients with end stage renal failure. Fine-needle aspiration biopsy seems to be a sensitive exam for diagnosis, but thyroidectomy remains sometimes necessary to rule out malignancy or release compressive symptoms.
