OBJECTIVES: Colchicine is the main treatment for FMF. Although a number of individuals with FMF are intolerant/resistant to colchicine, there is no standard definition of colchicine resistance/intolerance. We developed a set of evidence-based core statements defining colchicine resistance/intolerance in patients with FMF that may serve as a guide for clinicians and health authorities. METHODS: A set of statements was identified using a modified-Delphi consensus-based approach. The process involved development of an initial colchicine resistance/intolerance-related questionnaire derived from a systematic literature review. The questionnaire, which was completed by an international panel of 11 adult and paediatric rheumatologists with expertise in FMF, was analysed anonymously. The results informed draft consensus statements that were discussed by a round-table expert panel, using a nominal group technique to agree on the selection and wording of the final statements. RESULTS: Consensus among the panel was achieved on eight core statements defining colchicine resistance/intolerance in patients with FMF. A definition of resistance was agreed upon that included recurrent clinical attacks (average one or more attacks per month over a 3-month period) or persistent laboratory inflammation in between attacks. Other core statements recognize the importance of assessing treatment adherence, and the impact of active disease and intolerance to colchicine on quality of life. CONCLUSION: Based on expert opinion, a set of evidence-based core statements defining colchicine resistance/intolerance in patients with FMF were identified to help guide clinicians and health authorities in the management of patients with FMF. © The Author(s) 2020.

Seven separate cases of SARS-CoV-2 infection were observed in as many healthcare workers (HCW), with a total of 395 contacts, and 23 (6%) secondary case,in a tertiary care paediatric hospital from February 24th to March 31st, 2020. A program of contact tracing and quarantine of SARS-CoV-2 positive HCW, screening of asymptomatic HCW, use of surgical masks, hand hygiene, social distancing and use of PPE in COVID-19 cases assistance prevented the spread of the virus to patients and blocked the diffusion within the hospital., Journal of Preventive Medicine and Hygiene, Vol. 62 No. 3 (2021): 2021623

BACKGROUND: TNF receptor-associated periodic syndrome (TRAPS) is a rare autoinflammatory disease caused by dominant mutation of the TNF super family receptor 1A (TNFRSF1A) gene. Data regarding long-term treatment outcomes are lacking. OBJECTIVE: To assess correlations of genotype-phenotypes in patients with TRAPS, as defined by the International Study Group for Systemic Autoinflammatory Diseases (INSAID) classification and Eurofever criteria, with treatment responses. METHODS: Data from 226 patients with variants of the TNFRSF1A gene and enrolled in the Eurofever registry were classified according to the INSAID classification in groups A (pathogenic or likely pathogenic variants), B (variants of uncertain significance or not classified variants), and C (benign or likely benign variants) and screened for Eurofever criteria. RESULTS: In group A (127 of 226 patients, 56%), all fulfilled Eurofever criteria and 20 of 127 patients (16%) developed AA amyloidosis. In group B (78 of 226 patients, 35%), 40 of 78 patients (51%) did not fulfill Eurofever criteria, displaying a lower incidence of abdominal pain (P < .02) and higher efficacy rate of on-demand nonsteroidal anti-inflammatory drugs (P 85% complete response). No patients on anti-IL-1 treatments developed AA amyloidosis, and 7 women with a history of failure to conceive had successful pregnancies. CONCLUSION: Anti-IL-1 drugs are the best maintenance treatment in patients with TRAPS. The diagnosis of TRAPS should be considered very carefully in patients of group B not fulfilling Eurofever criteria and group C, and colchicine may be preferable as the first maintenance treatment.

Background: Anakinra might improve the prognosis of patients with moderate to severe COVID-19 (ie, patients requiring oxygen supplementation but not yet receiving organ support). We aimed to assess the effect of anakinra treatment on mortality in patients admitted to hospital with COVID-19. Methods: For this systematic review and individual patient-level meta-analysis, a systematic literature search was done on Dec 28, 2020, in Medline (PubMed), Cochrane, medRxiv, bioRxiv, and the ClinicalTrials.gov databases for randomised trials, comparative studies, and observational studies of patients admitted to hospital with COVID-19, comparing administration of anakinra with standard of care, or placebo, or both. The search was repeated on Jan 22, 2021. Individual patient-level data were requested from investigators and corresponding authors of eligible studies; if individual patient-level data were not available, published data were extracted from the original reports. The primary endpoint was mortality after 28 days and the secondary endpoint was safety (eg, the risk of secondary infections). This study is registered on PROSPERO (CRD42020221491). Findings: 209 articles were identified, of which 178 full-text articles fulfilled screening criteria and were assessed. Aggregate data on 1185 patients from nine studies were analysed, and individual patient-level data on 895 patients were provided from six of these studies. Eight studies were observational and one was a randomised controlled trial. Most studies used historical controls. In the individual patient-level meta-analysis, after adjusting for age, comorbidities, baseline ratio of the arterial partial oxygen pressure divided by the fraction of inspired oxygen (PaO2/FiO2), C-reactive protein (CRP) concentrations, and lymphopenia, mortality was significantly lower in patients treated with anakinra (38 [11%] of 342) than in those receiving standard of care with or without placebo (137 [25%] of 553; adjusted odds ratio [OR] 0·32 [95% CI 0·20–0·51]). The mortality benefit was similar across subgroups regardless of comorbidities (ie, diabetes), ferritin concentrations, or the baseline PaO2/FiO2. In a subgroup analysis, anakinra was more effective in lowering mortality in patients with CRP concentrations higher than 100 mg/L (OR 0·28 [95% CI 0·17–0·47]). Anakinra showed a significant survival benefit when given without dexamethasone (OR 0·23 [95% CI 0·12–0·43]), but not with dexamethasone co-administration (0·72 [95% CI 0·37–1·41]). Anakinra was not associated with a significantly increased risk of secondary infections when compared with standard of care (OR 1·35 [95% CI 0·59–3·10]). Interpretation: Anakinra could be a safe, anti-inflammatory treatment option to reduce the mortality risk in patients admitted to hospital with moderate to severe COVID-19 pneumonia, especially in the presence of signs of hyperinflammation such as CRP concentrations higher than 100 mg/L.

Chronic non-bacterial osteomyelitis (CNO) or chronic recurrent multifocal osteomyelitis (CRMO) is an autoinflammatory disorder characterized by sterile bone osteolytic lesions. The aim of this study was to evaluate the demographic data and clinical, instrumental and therapeutic features at baseline in a large series of CNO/CRMO patients enrolled in the Eurofever registry.

An apparently unprovoked recurrent inflammation is the quintessential hallmark of autoinflammatory diseases (AIDs), a large and heterogeneous group of disorders in which there is poor regulation of the innate immune system with no clearly demonstrated autoimmune machinery involvement. Innate immunity pathways are diverse and our understanding of their molecular composition and function is continuously expanding. The impaired immune responses we observe in monogenic AIDs, mostly in the hereditary periodic fever syndromes, is officiated by target molecules of microbial origin (pathogen-associated molecular patterns) and also host molecules (danger-associated molecular patterns). Further crucial components of innate immune mechanisms that contribute differently in the deregulated inflammatory patterns of different AIDs include Toll-like receptors, Nod-like receptors, scaffolding proteins (such as the caspase recruitment domain of proteins), cytosolic DNA-sensing molecules, inflammatory multi-protein complexes (referred to as inflammasomes), complement system, and others. In recent years, the knowledge of protean molecular pathways responsible for the most common monogenic AIDs has expanded, in parallel with very recent extraordinary technological advances, allowing the identification and characterisation of some unknown aspects of the innate immunity. This review will list and describe the most common monogenic febrile syndromes belonging to AIDs and will focus on current insights dealing with their pathologic processes.

Introduction: Due to the paucity of randomised controlled studies concerning vaccination in children with rheumatic diseases, the level of evidence for recommendations for vaccinations in these children is low. Booster doses of live attenuated vaccines might be considered in children with rheumatic diseases treated with immunosuppressive therapy, but data from multicentre studies are lacking. Moreover, national vaccination programs, parental obligation to vaccinate their children and vaccine coverage rates vary greatly among countries. Objectives: To highlight differences in the current national vaccination policies, and to develop a platform for future multicentre initiatives for uniform vaccination practices for children with rheumatic diseases treated with immunosuppressive drugs. Methods: The PReS Vaccination working group was formed during the 2017 PReS meeting in Athens. Paediatric rheumatologists from 34 countries were invited to participate. Results: Data were collected from 25 countries who responded. Vaccinations are mandatory in 12/21 European countries (Croatia, Czech Republic, France, Greece, Hungary, Italy, Latvia, Poland, Serbia, Slovakia, Slovenia, Ukraine). The vaccination schedules and coverage differ among countries. The first MMR vaccine is recommended at 11-15 months- of-age in all countries and most recommend the second dose before 2 years-of-age or at 6 years ; however in Spain it is at 2-4 years, in the UK at 3-5 years, and in Hungary, The Netherlands, Estonia, Norway, Poland and Slovakia at the age of 9 years or later. Mandatory programs, as compared to optional vaccination, do not always ensure higher coverage. For example, in Australia, Israel, The Netherlands and Norway where vaccinations are optional, the vaccination rate is high, at around 95%. However, coverage for MMR fell below 95% in Croatia, Czech Republic, Serbia and Slovenia, where vaccination is mandatory. Vaccinations were optional in France and Italy ; however, due to low coverage, they are now mandatory. Conclusion: There are considerable differences amongst countries in vaccination programmes, coverage, and in parental obligation to vaccinate their child. A powerful anti-vaccine campaign has gained momentum in many countries and has resulted in a significant drop in vaccination coverage to a level that is no longer sufficient for herd immunity. This is especially dangerous for children with rheumatic diseases on immunosuppressive therapy. Our future goals are to prospectively examine the outcomes of live vaccination in children with rheumatic diseases who are treated with immunosuppressive drugs and hopefully to demonstrate that booster doses of live attenuated vaccines are safe and protective.
