Abstract
Pyrin is a cytosolic protein encoded by the MEFV gene, predominantly expressed in innate immune cells. Upon activation, it forms an inflammasome, a multimolecular complex that enables the activation and secretion of IL-1β and IL-18. In addition, the Pyrin inflammasome activates Gasdermin D leading to pyroptosis, a highly pro-inflammatory cell death. Four autoinflammatory syndromes are associated with Pyrin inflammasome dysregulation: familial Mediterranean fever, hyper IgD syndrome/mevalonate kinase deficiency, pyrin-associated autoinflammation with neutrophilic dermatosis, and pyogenic arthritis, pyoderma gangrenosum, and acne syndrome. In this review, we discuss recent advances in understanding the molecular mechanisms regulating the two-step model of Pyrin inflammasome activation. Based on these insights, we discuss current pharmacological options and identify a series of existing molecules with therapeutic potential for the treatment of pyrin-associated autoinflammatory syndromes.

Abstract
OBJECTIVES To develop a novel scoring system to predict colchicine resistance in Familial Mediterranean fever (FMF) based on the initial features of the patients. METHODS The medical records of patients were analyzed prior to the initiation of colchicine. After generating a predictive score in the initial cohort, it was applied to an independent cohort for external validation of effectiveness and reliability. RESULTS Among 1418 patients with FMF, 56 (3.9%) were colchicine resistant (cr) and 1312 (96.1%) were colchicine responsive. Recurrent arthritis (4 points), protracted febrile myalgia (8 points), erysipelas-like erythema (2 points), exertional leg pain (2 points), and carrying M694V homozygous mutation (4 points) were determined as the parameters for predicting cr-FMF in the logistic regression model. The cut-off value of 9 was 87% sensitive and 82% specific to foresee the risk of cr-FMF in the receiver operating characteristic. Validation of the scoring system with an independent group (cr-FMF = 107, colchicine responsive = 1935) revealed that the cut-off value was 82% sensitive and 79% specific to identify the risk of cr-FMF. CONCLUSIONS By constructing this reliable and predictor tool, we enunciate that predicting cr-FMF at the initiation of the disease and interfering timely before the emergence of complications will be possible.

Abstract
Familial Mediterranean fever (FMF) is an autoinflammatory disease which may cause endothelial dysfunction and arterial stiffness. In this study, we evaluated patients with FMF in terms of arterial stiffness indicators and investigated whether there was any difference according to colchicine response. This is a single-center, prospective, case-control study conducted on pediatric patients with FMF. Patients were categorized into 2 groups: patients on colchicine monotherapy (group 1) and patients who used anti-interleukin-1 (IL-1) plus colchicine (group 2). Patient age, mutations in the MEFV gene, overall duration of treatments, and general characteristics of symptoms were recorded. Laboratory values in an attack-free period were noted. Pulse wave velocity (PWV) was measured in all patients. Erythrocyte sedimentation rate and C-reactive protein, nocturnal hypertension, and PWV were higher in group 2. Arterial stiffness develops due to subclinical inflammation in patients with FMF. It is more pronounced in colchicine-resistant patients.

Abstract
OBJECTIVES The aim of this study was to investigate the clinical associations of the second allele mutations and the effect of genotype and presenting features on colchicine resistance in children with familial Mediterranean fever (FMF), carrying at least one M694V variant. METHODS The medical records of the patients diagnosed with FMF, in whom at least one allele M694V mutation was detected, were reviewed. Patients were grouped according to the genotype as M694V homozygotes, compound heterozygote M694V with an exon 10 mutation, compound heterozygote M694V with a variant of unknown significance (VUS), and M694V heterozygotes. Disease severity was assessed with the International Severity Scoring System for FMF. RESULTS Among the 141 patients included, homozygote M694V (43.3%) was the most frequent MEFV genotype. Clinical manifestations of FMF at diagnosis were not significantly different according to genotypic alterations except homozygote M694V. Besides, homozygous M694V was associated with a more severe disease, with more frequent comorbidities and colchicine-resistant disease. A lower disease severity score was observed in compound heterozygotes with VUS than in M694V heterozygotes (median 1 vs 2, p = 0.006). Regression analysis revealed that homozygous M694V, arthritis, and frequency of attacks were associated with an increased risk of colchicine-resistant disease. CONCLUSIONS Clinical manifestations of FMF at diagnosis with a M694V allele were predominantly influenced by the M694V rather than the second allele mutations. Although homozygous M694V was associated with the most severe form, the presence of compound heterozygosity with a VUS did not affect disease severity or clinical features. Homozygous M694V confers the highest risk of colchicine-resistant disease.

[PMID: 36661534 PMCID: PMC9857527 DOI: 10.3390/cimb45010048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 12/31/2022] [Accepted: 01/04/2023] [Indexed: 01/19/2023] Open
Abstract
Epigenetic modifications play a pivotal role in autoimmune/inflammatory disorders and could establish a bridge between personalized medicine and disease epidemiological contexts. We sought to investigate the role of epigenetic modifications beside genetic alterations in the MEFV gene in familial Mediterranean fever (FMF). The study comprised 63 FMF patients diagnosed according to the Tel Hashomer criteria: 37 (58.7%) colchicine-responders, 26 (41.3%) non-responders, and 19 matched healthy controls. MEFV mutations were detected using a CE/IVD-labeled 4-230 FMF strip assay. DNA methylation of MEFV gene exon 2 was measured using bisulfite modification and related to pyrin level, phenotypic picture, MEFV mutations, disease severity, serum amyloid A (SAA), CRP, ESR, disease severity, and colchicine response. Our results showed that FMF patients exhibited significantly higher methylation percentage (p < 0.001) and lower pyrin levels (p < 0.001) compared to the control. The MEFV gene M694I mutation was the most commonly reported mutation (p < 0.004). High methylation percentage of the MEFV exon 2 and low pyrin concentration were correlated with disease severity, high SAA, ESR levels, H-pylori, and renal calculi. In conclusion, this study highlights the relation between high methylation percentage, reduced pyrin level, and different biomarkers in FMF, which underscores their role in the pathogenesis of FMF and could be considered as potential therapeutic targets.

Abstract
Background: The purpose of this trial was to evaluate the effectiveness and safety of the IL-6 receptor antibody Tocilizumab (TCZ) in the treatment of Familial Mediterranean Fever (FMF). Methods: This was a randomized, double-blinded, placebo-controlled phase II trial in adult patients with active FMF and an inadequate response or intolerance to colchicine (crFMF). The physician’s global assessment of disease activity (PGA), based on a five-point scale for six symptoms, was used as a clinical score, which had to be >2 at screening, together with elevated c-reactive protein (CRP) or erythrocyte sedimentation rate (ESR) and serum amyloid A (SAA) levels, to be eligible for inclusion. Patients were randomized 1:1 to either receive monthly TCZ or a placebo over a period of 24 weeks. The primary endpoint was the number of patients achieving an adequate response to treatment at week 16, defined as a PGA of ≤2 and normalized ESR or CRP and normalized SAA. Results: We randomized 25 patients with a median age of 31 years. At week 16, an adequate treatment response was achieved by two patients in the TCZ and none of the patients in the placebo arm (p = 0.089). SAA levels normalized with TCZ, but not with the placebo (p = 0.015). Conclusion: In this first randomized, placebo-controlled study in patients with active crFMF, more patients in the TCZ arm experienced a response to treatment in comparison to those receiving the placebo. As the prevention of amyloidosis is a major treatment goal in FMF, the normalization of SAA in TCZ-treated patients is essential. These findings have to be confirmed in a larger trial.

Abstract
AIM To determine the factors associated with colchicine resistance and the effect of colchicine resistance on health-related quality of life (QoL) in patients with familial Mediterranean fever (FMF). METHODS Demographic and clinical features, MEFV gene mutations, and Pras disease severity scores were recorded. QoL was assessed using the Short Form-36 (SF-36) and FMF-QoL scales. Colchicine resistance was defined as at least 1 attack per month for 6 months at the maximum tolerated dose of colchicine in fully compliant patients. RESULTS The mean age of 118 patients (90 female, 28 male) with FMF was 38.4 ± 12.5 years. The percentage of colchicine-resistant patients was 19.5%. In univariable analysis, smoking (odds ratio [OR] = 2.885; 95% confidence interval [CI] = 1.104-7.539; P = 0.031), attack duration (OR = 1.955; 95% CI = 1.137-3.360; P = 0.015), presence of arthritis (OR = 5.235; 95% CI = 1.508-18.179; P = 0.009), and disease severity score (OR = 1.790; 95% CI = 1.334-2.402; P < 0.001) were associated with colchicine resistance. The FMF-QoL and subscales of SF-36 except for role emotional and vitality, were different between colchicine-resistant and non-resistant patients (P < 0.05). CONCLUSION Smoking, attack duration, presence of arthritis, and disease severity were associated with colchicine resistance in fully compliant FMF patients. Colchicine-resistant patients had poorer health-related QoL.

Abstract
OBJECTIVE To explore early features that can predict colchicine resistance in familial Mediterranean fever (FMF) patients. METHODS It included FMF cases who fulfilled the Yalcinkaya-Ozen criterion and were on colchicine for at least 6 months. Data were collected from medical files and interpreted with respect to clinical parameters including, the auto-inflammatory diseases activity index (AIDAI) and FMF severity score. FMF50 score assessed the treatment response. Laboratory findings and genetic analysis of MEFV mutations were evaluated according to the standard technique. Patients were classified into two groups according to their response to colchicine. Both groups were compared and significant variables entered into a logistic regression model to detect independent predictors. The diagnostic accuracy of these predictors was assessed using the receiver operating characteristic (ROC) curve. RESULTS 120 FMF children were included. After the exclusion of sixteen-non-complaint patients (13.3%), colchicine responders were 66 (63.4%) (group I), and colchicine resistant (group II) were 38 (36.5%). The fever duration after colchicine, number of attacks before/after colchicine, skin rash/erysipelas-like erythema, myalgia/protracted febrile myalgia, AIDIA before/after treatment, FMF severity score, and the maximum colchicine dose were higher in group II. Furthermore, high CRP and neutropenia were frequent in group II. However, different MEFV mutations including, M694V were similar between the two groups. Eight variables were detected in the regression analysis model and independent predictors were utilized to generate a scoring model. CONCLUSION : This study constructed a prediction model for colchicine nonresponse based on clinical and laboratory profiles. This model will be valuable for the treatment decisions of FMF children.

Abstract
Familial Mediterranean fever (FMF), the most frequent monogenic autoinflammatory disease, is manifested with recurrent and chronic inflammation and amyloid A (AA) amyloidosis, driven by overproduction of interleukin 1 (IL-1) through an activated pyrin inflammasome. Consequently, non-responsiveness to colchicine, the cornerstone of FMF treatment, is nowadays addressed by IL-1- blockers. Each of the two IL-1 blockers currently used in FMF, anakinra and canakinumab, has its own merits for FMF care. Here we focus on anakinra, a recombinant form of the naturally occurring IL-1 receptor antagonist, and explore the literature by using PubMed regarding the utility of anakinra in certain conditions of FMF. Occasionally we enrich published data with our own experience. To facilitate insights to anakinra role, the paper briefs some clinical, genetic, pathogenetic, and management aspects of FMF. The clinical settings of FMF covered in this review include colchicine resistance, AA amyloidosis, renal transplantation, protracted febrile myalgia, on- demand use, leg pain, arthritis, temporary suspension of colchicine, pediatric patients, and pregnancy and lactation. In many of these instances, either because of safety concerns or a necessity for only transient and short-term use, anakinra, due to its short half-life, is the preferred IL-1 blocker.

Abstract
BACKGROUND Familial Mediterranean fever (FMF), a hereditary auto-inflammatory disease, mainly affects ethnic groups living in the Mediterranean region. Early studies reported colchicine may potentially prevent FMF attacks. For people who are colchicine-resistant or intolerant, drugs such as anakinra, rilonacept, canakinumab, etanercept, infliximab or adalimumab might be beneficial. This is an update of the review last published in 2018. OBJECTIVES To evaluate the efficacy and safety of interventions for reducing inflammation in people with FMF. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase and four Chinese databases on in August 2021. We searched clinical trials registries and references listed in relevant reports. The last search was 17 August 2021. SELECTION CRITERIA We included randomized controlled trials (RCTs) of people with FMF, comparing active interventions (including colchicine, anakinra, rilonacept, canakinumab, etanercept, infliximab, adalimumab, thalidomide, tocilizumab, interferon-α and ImmunoGuard (herbal dietary supplement)) with placebo or no treatment, or comparing active drugs to each other. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodology. We assessed certainty of the evidence using GRADE. MAIN RESULTS We included 10 RCTs with 312 participants (aged three to 53 years), including five parallel and five cross-over designed studies. Six studies used oral colchicine, one used oral ImmunoGuard, and the remaining three used rilonacept, anakinra or canakinumab as a subcutaneous injection. The duration of each study arm ranged from one to eight months. There were inadequacies in the design of the four older colchicine studies and the two studies comparing a single to a divided dose of colchicine. However, the four studies of ImmunoGuard, rilonacept, anakinra and canakinumab were generally well-designed. We aimed to report on the number of participants experiencing an attack, the timing of attacks, the prevention of amyloid A amyloidosis, adverse drug reactions and the response of a number of biochemical markers from the acute phase of an attack; but no study reported on the prevention of amyloid A amyloidosis. Colchicine (oral) versus placebo After three months, colchicine 0.6 mg three times daily may reduce the number of people experiencing attacks (risk ratio (RR) 0.21, 95% confidence interval (CI) 0.05 to 0.95; 1 study, 10 participants; low-certainty evidence). One study (20 participants) of colchicine 0.5 mg twice daily showed there may be no difference in the number of participants experiencing attacks at two months (RR 0.78, 95% CI 0.49 to 1.23; low-certainty evidence). There may be no differences in the duration of attacks (narrative summary; very low-certainty evidence), or in the number of days between attacks: (narrative summary; very low-certainty evidence). Regarding adverse drug reactions, one study reported loose stools and frequent bowel movements and a second reported diarrhea (narrative summary; both very low-certainty evidence). There were no data on acute-phase response. Rilonacept versus placebo There is probably no difference in the number of people experiencing attacks at three months (RR 0.87, 95% CI 0.59 to 1.26; moderate-certainty evidence). There may be no differences in the duration of attacks (narrative summary; low-certainty evidence) or in the number of days between attacks (narrative summary; low-certainty evidence). Regarding adverse drug reactions, the rilonacept study reported there may be no differences in gastrointestinal symptoms, hypertension, headache, respiratory tract infections, injection site reactions and herpes, compared to placebo (narrative summary; low-certainty evidence). The study narratively reported there may be no differences in acute-phase response indicators after three months (low-certainty evidence). ImmunoGuard versus placebo The ImmunoGuard study observed there are probably no differences in adverse effects (moderate-certainty evidence) or in acute-phase response indicators after one month of treatment (moderate-certainty evidence). No data were reported for the number of people experiencing an attack, duration of attacks or days between attacks. Anakinra versus placebo A study of anakinra given to 25 colchicine-resistant participants found there is probably no difference in the number of participants experiencing an attack at four months (RR 0.76, 95% CI 0.54 to 1.07; moderate-certainty evidence). There were no data for duration of attacks or days between attacks. There are probably no differences between anakinra and placebo with regards to injection site reaction, headache, presyncope, dyspnea and itching (narrative summary; moderate-certainty evidence). For acute-phase response, anakinra probably reduced C-reactive protein (CRP) after four months (narrative summary; moderate-certainty evidence). Canakinumab versus placebo Canakinumab probably reduces the number of participants experiencing an attack at 16 weeks (RR 0.41, 95% CI 0.26 to 0.65; 1 study, 63 colchicine-resistant participants; moderate-certainty evidence). There were no data for the duration of attacks or days between attacks. The included study reported the number of serious adverse events per 100 patient-years was probably 42.7 with canakinumab versus 97.4 with placebo among people with colchicine-resistant FMF (moderate-certainty evidence). For acute-phase response, canakinumab probably caused a higher proportion of participants to have a CRP level of 10 mg/L or less compared to placebo (68% with canakinumab versus 6% with placebo; 1 study, 63 participants; moderate-certainty evidence). Colchicine single dose versus divided dose There is probably no difference in the duration of attacks at three months (MD -0.04 hours, 95% CI -10.91 to 10.83) or six months (MD 2.80 hours, 95% CI -5.39 to 10.99; moderate-certainty evidence). There were no data for the number of participants experiencing an attack or days between attacks. There is probably no difference in adverse events (including anorexia, nausea, diarrhea, abdominal pain, vomiting and elevated liver enzymes) between groups (narrative summary; moderate-certainty evidence). For acute-phase response, there may be no evidence of a difference between groups (narrative summary; low- to moderate-certainty evidence). AUTHORS' CONCLUSIONS There were limited RCTs assessing interventions for people with FMF. Based on the evidence, three times daily colchicine may reduce the number of people experiencing attacks, colchicine single dose and divided dose may not be different for children with FMF, canakinumab probably reduces the number of people experiencing attacks, and anakinra or canakinumab probably reduce CRP in colchicine-resistant participants; however, only a few RCTs contributed data for analysis. Further RCTs examining active interventions, not only colchicine, are necessary before a comprehensive conclusion regarding the efficacy and safety of interventions for reducing inflammation in FMF can be drawn.

Abstract
OBJECTIVES Colchicine is the fundamental treatment of familial Mediterranean fever (FMF). Still, 5-10% of patients are not in remission with colchicine treatment. A consensus could not be established for the definition of colchicine resistance in FMF. This study aimed to determine factors that help to predict colchicine resistance in pediatric FMF patients. METHODS Patients with FMF that age of diagnosis was under 18 years old were included in our study. Fifty colchicine responsive and 33 colchicine-resistant patients were stratified as groups 1 and 2, respectively. Patients' clinical and laboratory findings were evaluated. Logistic regression analysis was used to determine the risk factors of colchicine-resistant FMF. Receiver operating characteristic (ROC) curve analysis was used to identify and compare the predictive performances of colchicine-resistant FMF models. RESULTS Homozygous exon 10 MEFV mutations were frequent in group 2 (Group 1: 34 (68%), group 2: 32 (97%), p = .013). Univariate analysis showed that the age of onset of symptoms, age of diagnosis, chronic arthritis, myalgia and diarrhea during attacks, and the number of attacks, high ISSF and Pras score, high C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) values under colchicine treatment were risk factors for colchicine-resistant FMF. With multivariate analysis, the number of attacks (OR 1.418, CI (95%) 1.149-1.750, p = .001) and high ESR values (OR 1.129, CI (95%) 1.059-1.204, p<.001) were detected as independent risk factors for colchicine-resistant FMF. CONCLUSION The predictive factors were determined for pediatric colchicine-resistant FMF in our study. The results will help to early diagnosis and treatment of chronic inflammation in FMF.

Abstract
Hereditary systemic autoinflammatory diseases (SAIDs) are rare, often severe conditions characterised by mutations in the key regulators of innate immune responses. Dramatic advances in the molecular genetics and next-generation sequencing in the past decade enabled identification of novel mutations that play a pivotal role in the mechanistic pathways of inflammation. Although genetic testing may not always provide straightforward guidance in diagnosis and clinical decision making, through translational research, it sheds light into molecular immunopathogenesis, particularly in IL-1 inflammasome and cytokine signalling pathways. These remarkable insights provided a better understanding of autoinflammatory conditions and their association with the innate and adaptive immune systems, as well as leading to development of cytokine-targetted biologic treatments. Use of targetted therapeutics not only helps control disease flares, reduce acute-phase responses and prevent devastating complications such as amyloidosis, but also improves health-related quality of lives and support patients to pursue almost a normal life. Herein, we discuss the commonest monogenic SAIDs, describe their immunopathology, and summarise the approaches in the management and targetted treatment of these conditions, including presentation of novel data based on a cohort of children with these rare diseases from a single quaternary referral centre in London.

Abstract
BACKGROUND Follow-up is crucial to detect asymptomatic complications of familial Mediterranean fever (FMF). The current European League Against Rheumatism recommendations state that patients with FMF should be evaluated at least every 6 months to monitor attacks, acute phase response, and proteinuria. OBJECTIVES This study aimed to assess compliance of FMF patients with regular follow-up visits and the associated factors. METHODS Adult patients with a diagnosis of FMF who had their initial visit at least over 1 year ago were included. Demographic and socioeconomic data, family history, and comorbid diseases were obtained from medical records. The International Severity Score for FMF and the Autoinflammatory Disease Damage Index scores were calculated. We defined patients as "compliant with follow-up visits" both if they had at least 2 visits during the previous year and a compatible physician's assessment. The characteristics of the compliant and noncompliant patients were compared, and multivariable logistic regression analysis was used to determine the factors influencing visit compliance. RESULTS Four hundred seventy-four patients with FMF were included. Two hundred thirty (48.5%) were compliant, and 244 (51.5%) were noncompliant with follow-up visits. A family history of FMF in parents, the absence of a family history of FMF in siblings, treatment with biologic agents, concomitant medication use, multisite involvement during FMF attacks, and treatment satisfaction were independent predictors of visit compliance. CONCLUSIONS Only half of the patients with FMF were compliant with follow-up visits. Better strategies should be implemented to increase the compliance of FMF patients. Identifying independent predictors would help to build one.

Abstract
OBJECTIVES To evaluate the efficacy and safety of canakinumab in Japanese patients with colchicine-resistant or colchicine-intolerant familial Mediterranean fever (FMF) in a real-world clinical setting. METHODS We reviewed 13 Japanese FMF patients to whom canakinumab was introduced during the period of October 2017 to December 2020. All patients were diagnosed as FMF according to Tel-Hashomer criteria. We performed genetic analyses for Mediterranean fever or MEFV by targeted next-generation sequencing. Efficacy was assessed by attack frequency and the percentage of patients who achieved attack improvement at 24 weeks. Safety was assessed by adverse events observed during canakinumab treatment. RESULTS The median duration and follow-up of canakinumab treatment were 13 and 16 months, respectively. The median attack frequency was 0.50 [0.30-1.00] at 24 weeks, which was a significant decrease from 2.00 [0.85-2.88] at the time of induction (p = .019). There were three patients (23%) with complete resolution of attacks at 24 weeks. No serious adverse events were observed. However, one patient had small intestinal ulceration which led to the discontinuation of canakinumab. CONCLUSIONS Although the number of cases is small, this study suggests that canakinumab is efficacious and safe for use in Japanese patients with colchicine-resistant or colchicine-intolerant FMF in a real-world clinical setting in Japan.

Abstract
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.

Abstract
BACKGROUND The efficacy of anti-interleukin-1 (IL-1) drugs in kidney transplant patients with FMF-AA who developed colchicine resistance has not been clearly demonstrated. METHOD Thirty nine kidney transplant recipients with FMF-AA were evaluated. Group 1 consisted of patients who were in remission after transplantation with colchine and Group 2 included those who developed colchicine resistance. RESULTS The mean follow-up of the patients was 88.5 ± 61.9 months. Following the treatment with IL-1 antagonists; serum Amyloid A (SAA) averages (79.4 ± 35.3 mg/L) as well as the average number of hospitalizations per month due to FMF episodes (1.4 ± 0.5 times/month) decreased significantly (26.6 ± 25.9 mg/L and 0.1 ± 0.3 times/month) (p < .001). Rates of death with a functional graft were 30% and 0% in group 1 and 2 (p = .086). Biopsy-proven AA amyloidosis recurrence in the allograft was observed in 11 of 19 (58%) and seven of nine (78%) patients in group 1 and 2, respectively. Interestingly, glomerular amyloid deposition was not present in the vast majority of biopsies. De novo vasculer amyloid deposition was observed during treatment. CONCLUSION IL-1 antagonist drug and colchicine combination almost completely prevented acute FMF attacks in kidney transplant patients with colchicine resistance. However, amyloid accumulation did not cease during IL-1 antagonist drug treatment.

Abstract
PURPOSE Familial Mediterranean Fever (FMF) and Pyrin-Associated Autoinflammation with Neutrophilic Dermatosis (PAAND) are clinically distinct autoinflammatory disorders caused by mutations in the pyrin-encoding gene MEFV. We investigated the transcriptional, phenotypical, and functional characteristics of patient neutrophils to explore their potential role in FMF and PAAND pathophysiology. METHODS RNA sequencing was performed to discover transcriptional aberrancies. The phenotypical features, degranulation properties, and phagocytic capacity of neutrophils were assessed by flow cytometry. Production of reactive oxygen species (ROS), myeloperoxidase (MPO) release, and chemotactic responses were investigated via chemiluminescence, ELISA, and Boyden chamber assays, respectively. RESULTS Neutrophils from PAAND and FMF patients showed a partially overlapping, activated gene expression profile with increased expression of S100A8, S100A9, S100A12, IL-4R, CD48, F5, MMP9, and NFKB. Increased MMP9 and S100A8/A9 expression levels were accompanied by high plasma concentrations of the encoded proteins. Phenotypical analysis revealed that neutrophils from FMF patients exhibited an immature character with downregulation of chemoattractant receptors CXCR2, C5aR, and BLTR1 and increased expression of Toll-like receptor 4 (TLR4) and TLR9. PAAND neutrophils displayed an increased random, but reduced CXCL8-induced migration. A tendency for enhanced random migration was observed for FMF neutrophils. PAAND neutrophils showed a moderately but significantly enhanced phagocytic activity as opposed to neutrophils from FMF patients. Neutrophils from both patient groups showed increased MPO release and ROS production. CONCLUSIONS Neutrophils from patients with FMF and PAAND, carrying different mutations in the MEFV gene, share a pro-inflammatory phenotype yet demonstrate diverse features, underscoring the distinction between both diseases.

Abstract
OBJECTIVE In the familial Mediterranean fever (FMF) clinic, arthritis is among the most common symptoms, and it generally responds well to colchicine treatment. However, cases of patients with chronic prolonged colchicine-resistant arthritis have been reported, and there are inadequate studies on the treatments to be used for such patients. METHODS This study included 18 patients diagnosed with FMF who had colchicine-resistant chronic arthritis and received anti-interleukin (IL)-1 treatment for at least 1 year. The clinical and laboratory data of the patients were retrospectively retrieved from the database of our hospital. RESULTS Remission was achieved in arthritis attacks in 16 of 18 patients who started anti-IL-1 therapy because of colchicine-resistant chronic arthritis. The clinical and laboratory values of the other 2 patients improved, but complete remission could not be achieved. The treatment dose of colchicine was reduced with anti-IL-1 therapy. In addition to the improvement in arthritis symptoms, remission was achieved in other clinical findings of FMF by anti-IL-1 therapy. In this study, with an average follow-up time of 33 months, no adverse effects requiring discontinuation were observed in any patient. CONCLUSION Anti-IL-1 therapy is effective and reliable in the treatment of colchicine-resistant chronic FMF arthritis. The efficacy of anti-IL-1 therapy was realized without concomitant disease-modifying antirheumatic drug therapy, despite the reduction in colchicine dose.

Abstract
Introduction: Familial Mediterranean fever (FMF) patients had 5-10% colchicine resistance. Although FMF attacks are characterized by acute phase elevation, there are no biomarkers that can show colchicine resistance yet. The serum endocan levels may elevate in inflammatory and auto-inflammatory diseases. Objectives: This study aimed to evaluate serum endocan levels in FMF patients according to whether attack and colchicine resistance or not and also compare them with classical acute phase reactants. Methods: In this single-center and cross-sectional study, a total of 111 FMF patients and 60 healthy individuals were enrolled. All patients' basic demographic and clinical data were recorded and blood samples were collected. Results: A total of 46 (41.4%) FMF patients had colchicine resistance. In comparison to the FMF patients according to colchicine response, colchicine resistance patients had a significantly higher median (IQR) endocan levels than colchicine responsive patients [36.98 ng/ml (97.41) vs. 13.57 ng/ml (27.87), p = 0.007], but there were no differences between in terms of median ESR and CRP levels. Inversely, serum endocan levels were similar during an attack and attack-free period in FMF patients, although ESR and CRP levels were significantly different. Interestingly, the highest serum endocan levels were in the control group. Conclusion: In conclusion, serum endocan levels were higher in colchicine resistance than colchicine responsive patients, but attack state had no effect on serum endocan levels in our study. Unlike ESR and CRP, serum endocan may be a novel biomarker for detection of colchicine resistance and distinguish the FMF attacks.

Effectiveness of Canakinumab in Colchicine- and Anakinra-Resistant or -Intolerant Adult Familial Mediterranean Fever Patients: A Single-Center Real-Life Study. J Clin Rheumatol 2020; 26:7-13. [PMID: 30048391 DOI: 10.1097/rhu.0000000000000873] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/25/2022]
Abstract
OBJECTIVE We aimed to present our single-center real-life experience of canakinumab use in adult patients with familial Mediterranean fever (FMF). METHODS Data were derived from the Gazi FMF cohort, which was established in 2010. From that year, all patients with FMF were registered. The impact of FMF on their lives was tracked by either an FMF diary or mobile phone application (FMF-AIDD, free to download in App Store and Google Play). The records of patients who were treated with canakinumab were reviewed. RESULTS Twenty-three adult patients with FMF (65% female) were enrolled in this study. The median age was 32 years (min-max, 24-58 years), and the disease duration was 26 years (14-59 years). A total of 86% of patients harbored homozygous or compound heterozygous exon 10 MEFV mutations. Indications for interleukin 1 inhibitor use were colchicine resistance (n = 12) or intolerance (n = 2), amyloidosis (n = 7), and chronic manifestations of the disease (n = 2). All patients used anakinra before. The median duration of canakinumab use was 7 months (min-max, 1-44 months). Pre- and post-canakinumab periods were compared. Attack severity, duration, frequency, C-reactive protein level, and erythrocyte sedimentation rate were significantly improved (p ≤ 0.01), whereas serum creatinine and alanine aminotransferase levels remained the same (p = 0.27 and p = 0.74, respectively). Canakinumab achieved complete disease remission in 14 patients (60%). Canakinumab was discontinued in 7 patients. The reasons for discontinuation were pregnancy (n = 2), dominance of axial spondyloarthropathy (n = 2), inflammatory bowel disease, patient's refusal, and weight gain. CONCLUSIONS Canakinumab is effective in the prevention of FMF bouts without severe adverse effects. Treatment with canakinumab in an individualized dose and interval may be a reasonable choice for colchicine- and anakinra-resistant or -intolerant adult patients with FMF and those with chronic manifestations of disease.

Abstract
Microtubules (MTs) are highly dynamic polymers that constitute the cellular cytoskeleton and play a role in multiple cellular functions. Variability characterizes biological systems and is considered a part of the normal function of cells and organs. Variability contributes to cell plasticity and is a mechanism for overcoming errors in cellular level assembly and function, and potentially the whole organ level. Dynamic instability is a feature of biological variability that characterizes the function of MTs. The dynamic behavior of MTs constitutes the basis for multiple biological processes that contribute to cellular plasticity and the timing of cell signaling. Colchicine is a MT-modifying drug that exerts anti-inflammatory and anti-cancer effects. This review discusses some of the functions of colchicine and presents a platform for introducing variability while targeting MTs in intestinal cells, the microbiome, the gut, and the systemic immune system. This platform can be used for implementing novel therapies, improving response to chronic MT-based therapies, overcoming drug resistance, exerting gut-based systemic immune responses, and generating patient-tailored dynamic therapeutic regimens.

Abstract
Familial Mediterranean Fever (FMF) is the most prevalent genetic autoinflammatory disorder. In most patients, treatment with colchicine can prevent attacks of fever and inflammation. However, 5%-10% of patients are resistant to colchicine treatment, while a similar percentage cannot tolerate colchicine in doses needed to prevent attacks. For these patients, Canakinumab, a full human antibody against IL-1β, has been approved recently by the FDA and EMA. In this article, we present a systematic review of the long-term efficacy, safety, and tolerability of Canakinumab in FMF patients who cannot tolerate colchicine or who are resistant to colchicine treatment.

Abstract
Objective: Prodrome is defined by manifestations that precede a familial Mediterranean fever (FMF) attack and predict its emergence. We aimed to determine the frequency, characteristics, and clinical determinants of prodrome in patients with FMF.Method: This cross-sectional study was conducted in a tertiary rheumatology clinic. During the clinical interview, all patients completed a standardized questionnaire about the pre-attack period. Prodrome was defined as the presence of any recurrent pre-attack manifestation occurring at least 4 h before an attack. Patients were classified according to whether they had prodrome of any kind of attack.Results: The study enrolled 401 patients aged 37.7 ± 11.0 years (mean ± sd). Male gender, M694V/M694V, homozygous MEFV mutation, peritonitis, pleuritis, and arthritis were more frequent in prodrome-positive patients. Altogether, 141 patients (35.2%) had prodrome. Male gender and ever having attack types of peritonitis or arthritis were independent clinical determinants of prodrome [relative risk (95% confidence interval): 1.72 (1.07-2.76), p = 0.02; 4.27 (1.80-10.1), p = 0.001; 1.77 (1.04-3.04), p = 0.04, respectively]. Age, MEFV mutations, pleuritis, and erysipelas-like erythema were not clinical determinants.Conclusions: All FMF patients, particularly males and patients who had peritonitis or arthritis at any time, should be questioned about prodrome. Prodrome should be analysed in terms of elucidating the pathogenesis of FMF and as an opportunity for a secondary prevention strategy for impending attacks. This study may shed light on prodrome for future cytokine or drug studies with the purpose of developing new cost-effective treatment protocols irrespective of colchicine resistance.

Abstract
Starting from 1972, colchicine is known as the most useful drug for prevention of familial Mediterranean fever attacks. However, some patients do not respond to colchicine treatment, even taken in high doses. Despite the fact, that different hypotheses have been proposed, the molecular mechanisms of colchicine resistance are not completely clear. It is generally known, that colchicine binds β-tubulin and inhibits microtubules polymerization. The β-tubulin gene has SNPs, which lead to amino acid substitutions, and some of them are located in colchicine binding site (CBS). We have assumed, that this SNPs can affect tubulin-colchicine interaction and might be the reason for colchicine resistance. With this in mind, we modeled 7 amino acid substitutions in CBS, performed molecular dynamics simulations of tubulin-colchicine complex and calculated binding energies for every amino acid substitution. Thus, our study shows, that two amino acid substitutions in the β-tubulin, namely A248T and M257V, reduce binding energy for approximately 2-fold. Based on this, we assume, that these amino acid substitutions could be the reason for colchicine resistance. Thus, our study gives a new insight into colchicine resistance mechanism and provides information for designing colchicine alternatives, that could be effective for colchicine resistant patients.

Abstract
Familial Mediterranean fever (FMF) is the most common monogenic auto-inflammatory disease characterized by recurrent attacks of fever and serositis. Although colchicine is the first line treatment in FMF, 5-10% of patients do not respond to colchicine. Canakinumab, an anti-IL-1β monoclonal antibody, has been reported to be effective and safe in colchicine-resistant FMF patients, but the adequate duration and interval of treatment is still a matter of debate. Aim of this study was to evaluate the success of the standardized treatment protocol for canakinumab applied in our Pediatric Rheumatology Department in colchicine-resistant FMF cases with a review of the literature. Nine patients included in this study had indications for canakinumab use as colchicine resistance and recurrent corticosteroid need for pleural/pericardial effusions. Canakinumab was administered monthly for 6 months (initial treatment), bimonthly for 6 months (maintenance treatment), then treatment was discontinued. For the patients who developed a new attack after one-year treatment period, canakinumab was readministered with 3-month intervals (continuation treatment). The mean follow-up time beginning from the first canakinumab injection was 24.3 ± 10.2 (6-33) months. None of the patients had an attack during the first-year treatment. Four of the patients developed an attack 9.0 ± 2.9 (6-12) months after discontinuation of treatment and switched to the continuation treatment period, with no more attacks. We suggest that this standard protocol may be used successfully in colchicine-resistant FMF patients.

Abstract
Familial Mediterranean Fever (FMF), the most common monogenic inflammatory disease, is mainly treated by oral Colchicine. However, 5% of patients are considered non-responders and, therefore, candidates for biologic therapy. Intravenous (IV) Colchicine treatment has been shown to be effective and safe in adult patients. The objective of this study was to evaluate the safety of IV Colchicine for pediatric FMF patients in our hospital, refractory to oral Colchicine, by reviewing their medical records. Inclusion criteria were all patients with FMF who commenced treatment with IV Colchicine before the age of 18 years, and received at least 6 months of IV therapy. The patients completed questionnaires to assess the efficacy of the treatment. Between 2004 and 2017, 7 pediatric FMF patients receiving maximal oral Colchicine doses and deemed non-responders were treated with weekly IV Colchicine, including 38 cumulative patient years of follow-up data (a full blood count, renal and liver function tests). All patients were homozygous for the M694V genotype. Long-term follow-up showed normal laboratory results with no Colchicine-related hospital admissions or toxicity. Global health assessment and the number of disease-free days have significantly improved (P < 0.05). Prolonged IV Colchicine use is described in pediatric FMF patients for the first time, with an excellent safety profile in our population, and decrease in intensity and frequency of attacks. In the biological era, IV Colchicine, although not leading to complete remission, may be considered a second-line option in countries where anti-interleukin 1 blockers are not available, or as a third-line option in case of failure to respond to biologics.

Abstract
OBJECTIVE The objective of this study was to assess the impact of Familial Mediterranean Fever (FMF) attacks on daily physical activity and detect FMF attacks using a connected activity tracker. METHODS Patients with FMF according to the Tel-Hashomer criteria were included in this prospective observational study. Attack-related data were collected weekly via phone call to avoid memory bias. Median steps in attack and attack-free days were calculated and compared using the Wilcoxon rank test. Sensitivity and specificity threshold for capturing attacks was set to two thirds of median steps per day in the whole observation period. RESULTS Twelve patients participated in the study. The median age of patients was 26 (18-32) years, and 7 (58.3%) of them were male. Patients with attacks (n = 10) walked a median of 6990 (4552-11,531) steps per day in attack-free days, whereas this number decreased to a median of 1841 (590-4783) steps in attack days (p = 0.005). The activity tracker captured 42 of 45 attack days and 312 of 361 attack-free days. The cutoff value had 93% sensitivity and 86% specificity for capturing attacks. CONCLUSIONS FMF attacks significantly impair the physical activity of patients. Activity tracking may be a reasonable method to document FMF attacks. This might prevent errors due to memory bias and help accurately identify and treat patients with FMF.

Abstract
Colchicine is the mainstay of treatment for familial Mediterranean fever (FMF). Intravenous (IV) colchicine, administered over several months, has been shown to be effective for FMF patients unresponsive to oral colchicine. The objective of this study was to evaluate the efficacy and safety of long-term IV colchicine treatment in oral colchicine-resistant FMF. We analyzed data of 15 patients with frequent FMF attacks, despite a maximal tolerated dose of oral colchicine (2-3 mg/day), who were treated with weekly IV injections of 1 mg of colchicine for at least 12 months. Treatment efficacy was determined by changes in frequency, duration and severity of FMF attacks. Safety was assessed according to adverse events. The mean duration of IV colchicine treatment was 5.16 ± 2.85 years. Decreases were observed from pre-treatment period in the monthly mean rates of abdominal attacks (from 5.6 ± 3.7 to 1.9 ± 3.3, p = 0.0009), joint attacks (from 6.5 ± 5.1 to 1.6 ± 1.6, p = 0.01) and overall attacks (from 22.3 ± 16.2 to 7.4 ± 5.7, p = 0.002) as well as in the mean duration (from 3.8 ± 1.5 to 2.4 ± 1.1 days per attack, p = 0.008) and severity of attacks (from 9.9 ± 0.3 to 5.7 ± 2.6, on a scale of 0-10, p < 0.05). The rate of adverse events was low, and they were mainly gastrointestinal. No severe or serious adverse events were recorded. Long-term treatment with IV colchicine in patients unresponsive to oral colchicine therapy is effective and safe.

Abstract
BACKGROUND Familial Mediterranean fever, a hereditary auto-inflammatory disease, mainly affects ethnic groups living in the Mediterranean region. Early studies reported colchicine as a potential drug for preventing attacks of familial Mediterranean fever. For those people who are colchicine-resistant or intolerant, drugs such as rilonacept, anakinra, canakinumab, etanercept, infliximab, thalidomide and interferon-alpha might be beneficial. This is an updated version of the review. OBJECTIVES To evaluate the efficacy and safety of interventions for reducing inflammation in people with familial Mediterranean fever. SEARCH METHODS We used detailed search strategies to search the following databases: CENTRAL; MEDLINE; Embase; Chinese Biomedical Literature Database (CBM); China National Knowledge Infrastructure Database (CNKI); Wan Fang; and VIP. In addition, we also searched the clinical trials registries including ClinicalTrials.gov, the International Standard Randomized Controlled Trial Number Register, the WHO International Clinical Trials Registry Platform and the Chinese Clinical Trial Registry, as well as references listed in relevant reports.Date of last search: 21 August 2018. SELECTION CRITERIA Randomized controlled studies (RCTs) of people diagnosed with familial Mediterranean fever, comparing active interventions (including colchicine, anakinra, rilonacept, canakinumab, etanercept, infliximab, thalidomide, interferon-alpha, ImmunoGuard™ (a herbal dietary supplement) and non-steroidal anti-inflammatory drugs) with placebo or no treatment, or comparing active drugs to each other. DATA COLLECTION AND ANALYSIS The authors independently selected studies, extracted data and assessed risk of bias. We pooled data to present the risk ratio or mean difference with their 95% confidence intervals. We assessed overall evidence quality according to the GRADE approach. MAIN RESULTS We included nine RCTs with a total of 249 participants (aged three to 53 years); five were of cross-over and four of parallel design. Six studies used oral colchicine, one used oral ImmunoGuard™ and the remaining two used rilonacept or anakinra as a subcutaneous injection. The duration of each study arm ranged from one to eight months.The three studies of ImmunoGuard™, rilonacept and anakinra were generally well-designed, except for an unclear risk of detection bias in one of these. However, some inadequacy existed in the four older studies on colchicine, which had an unclear risk of selection bias, detection bias and reporting bias, and also a high risk of attrition bias and other potential bias. Neither of the two studies comparing a single to a divided dose of colchicine were adequately blinded, furthermore one study had an unclear risk of selection bias and reporting bias, a high risk of attrition bias and other potential bias.We aimed to report on the number of participants experiencing an attack, the timing of attacks, the prevention of amyloid A amyloidosis, any adverse drug reactions and the response of a number of biochemical markers from the acute phase of an attack, but data were not available for all outcomes across all comparisons.One study (15 participants) reported a significant reduction in the number of people experiencing attacks at three months with 0.6 mg colchicine three times daily (14% versus 100%), risk ratio 0.21 (95% confidence interval 0.05 to 0.95) (low-quality evidence). A further study (22 participants) of 0.5 mg colchicine twice daily showed no significant reduction in the number of participants experiencing attacks at two months (low-quality evidence). A study of rilonacept in individuals who were colchicine-resistant or intolerant (14 participants) also showed no reduction at three months (moderate-quality evidence). Likewise, a study of anakinra given to colchicine-resistant people (25 participants) showed no reduction in the number of participants experiencing an attack at four months (moderate-quality evidence).Three studies reported no significant differences in duration of attacks: one comparing colchicine to placebo (15 participants) (very low-quality evidence); one comparing single-dose colchicine to divided-dose colchicine (90 participants) (moderate-quality evidence); and one comparing rilonacept to placebo (14 participants) (low-quality evidence). Three studies reported no significant differences in the number of days between attacks: two comparing colchicine to placebo (24 participants in total) (very low-quality evidence); and one comparing rilonacept to placebo (14 participants) (low-quality evidence).No study reported on the prevention of amyloid A amyloidosis.One study of colchicine reported loose stools and frequent bowel movements (very low-quality evidence) and a second reported diarrhoea (very low-quality evidence). The rilonacept study reported no significant differences in gastrointestinal symptoms, hypertension, headache, respiratory tract infections, injection site reactions and herpes, compared to placebo (low-quality evidence). The ImmunoGuard study observed no side effects (moderate-quality evidence). The anakinra study reported no significant differences between intervention and placebo, including injection site reaction, headache, presyncope, dyspnea and itching (moderate-quality evidence). When comparing single and divided doses of colchicine, one study reported no difference in adverse events (including anorexia, nausea, diarrhoea, abdominal pain, vomiting and elevated liver enzymes) between groups (moderate-quality evidence) and the second study reported no adverse effects were detected.The rilonacept study reported no significant reduction in acute phase response indicators after three months (low-quality evidence). In the ImmunoGuard™ study, these indicators were not reduced after one month of treatment (moderate-quality evidence). The anakinra study, reported that C-reactive protein was significantly reduced after four months (moderate-quality evidence). One of the single dose versus divided dose colchicine studies reported no significant reduction in acute phase response indicators after eight months (low-quality evidence), while the second study reported no significant reduction in serum amyloid A concentration after six months (moderate-quality evidence). AUTHORS' CONCLUSIONS There were limited RCTs assessing interventions for people with familial Mediterranean fever. Based on the evidence, three times daily colchicine appears to reduce the number of people experiencing attacks, colchicine single dose and divided dose might not be different for children with familial Mediterranean fever and anakinra might reduce C-reactive protein in colchicine-resistant participants; however, only a few RCTs contributed data for analysis. Further RCTs examining active interventions, not only colchicine, are necessary before a comprehensive conclusion regarding the efficacy and safety of interventions for reducing inflammation in familial Mediterranean fever can be drawn.

Abstract
Colchicine is an alkaloid which was originally extracted from bulbs of a plant called Colchicum autumnale (meadow saffron). Its active pharmacological component was isolated in 1820 and in 1833 the active ingredient was purified and named colchicine. It consists of three hexameric rings termed A, B, and C. It was first recommended for the treatment of gout by Alexander of Tralles in the sixth century AD. Later it has been employed for suggested and approved indications including primary biliary cirrhosis (PBC), alcohol induced hepatitis, psoriasis, Behçet disease, Sweet syndrome, scleroderma, sarcoidosis and amyloidosis. Perhaps the most effective results have been obtained in the prophylaxis of familial Mediterranean fever (FMF). Colchicine is absorbed in the jejunum and ileum and is trapped in the body tissues. It is metabolized in the liver and the intestine by cytochrome P (CYP) 450 3A4 and P-glycoprotein (PGY) 1. Colchicine is excreted mainly by the biliary system, intestines and the kidneys. It has a narrow therapeutic range, but with normal liver and kidney functions is relatively safe and can be used during pregnancy, nursing and in infants. The main mechanism of action of colchicine is probably through interaction with microtubules affecting leukocyte chemotaxis, thereby suppressing inflammation. The blood level of colchicine may be affected by concomitant drug administration and therefore, caution should be exercised when such medications are added.

On demand use of anakinra for attacks of familial Mediterranean fever (FMF). Clin Rheumatol 2018; 38:577-581. [PMID: 30062447 DOI: 10.1007/s10067-018-4230-z] [Citation(s) in RCA: 27] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2018] [Revised: 06/22/2018] [Accepted: 07/23/2018] [Indexed: 10/28/2022]
Abstract
To evaluate the efficacy of on-demand use of anakinra in patients with crFMF. The Gazi FMF cohort was established in the year 2010, and from that date, 689 patients with FMF diagnosed according to the Tel Hashomer criteria were registered. Attack type, duration, severity, and their impact on life were collected either by disease diaries or a mobile phone application (FMF AIDD, AppStore, and Playstore). A retrospective cohort analysis was made from records of patients who have ever been treated with IL-1 inhibitors. A total of 78 patients were treated with IL-1 inhibitors in our cohort. Among these, 15 patients were identified who received on-demand anakinra. Rationale for on-demand use was prominent prodrome or trigger for attacks and patient's personal claim. Six patients were switched from regular use and nine were directly started as on-demand use. All were using background colchicine in maximum tolerated doses. None of the patients had evidence of persistently elevated acute phase reactants or proteinuria. The median duration of on-demand anakinra use was 6 (3-36) months. Pre- and post- on-demand anakinra periods were compared. Patient reported attack severity (p = 0.002), duration (p = 0.001), frequency (p = 0.001), absenteeism (p = 0.002), and presenteeism (p = 0.002) were significantly improved. On-demand anakinra prevented progression of prodromes to full-blown attacks which was demonstrated by decrease in the rate of attack/prodrome ratio (p = 0.02). On-demand anakinra can be continued in ten subjects on long-term. On-demand anakinra significantly improved FMF attacks in certain patients which suggest this approach would be of benefit in daily practice in selected patients.

Abstract
BACKGROUND Familial Mediterranean fever and celiac disease share some common clinical features such as abdominal pain, diarrhea, arthralgia and arthritis. Also, both of the diseases are associated with many inflammatory and autoimmune diseases. Previous studies have shown the association between familial Mediterranean fever (FMF) and different clinical conditions. OBJECTIVE We aimed to investigate the relationship between celiac disease and colchicine-resistant familial Mediterranean fever (crFMF) disease. METHODS This prospective study was conducted at the Department of Pediatric Gastroenterology and Pediatric Rheumatology from October 2015 to August 2016. A total of 24 patients with crFMF were included in the study. We used 60 sex- and age-matched healthy subjects as a control group. Levels of total IgA and tissue transglutaminase (tTG) IgA antibody were measured in both groups. Those with increased level of tTG IgA were tested for anti-endomysium IgA antibodies (EMA). Gastroduodenoscopy and intestinal biopsy were planned for a definite diagnosis of celiac disease in patients with positive EMA. RESULTS Of the 24 patients in this study, 18 (75.0%) were female. Only 4 (16.6%) of 24 patients were positive for tTG IgA. Patients with positive tTG IgA were then tested for EMA IgA antibodies and none of them had a positive result. Only one (1.6%) subject from the control group was positive for tTG IgA but EMA positivity was not detected. CONCLUSION We did not found celiac disease in 24 children with crFMF. Since crFMF disease is rarely seen in general population, further studies with more patients are needed to provide more precise interpretation.

Abstract
BACKGROUND Familial Mediterranean fever (FMF) is an autoinflammatory disease characterized by recurrent serosal inflammation with fever, which can result in amyloid deposition. Anti-interleukin-1 drugs emerge as a therapeutic option for colchicine-resistant patients. In this study, we aimed to document our experience with canakinumab use in kidney transplant recipients who developed AA amyloidosis due to FMF. METHODS A total of nine patients with FMF amyloidosis treated with canakinumab were enrolled. Laboratory and clinical data were collected from the patient files, electronic database of the hospital and with interviews. RESULTS Five of the patients were male and four were female (median age: 33, range: 27-62 years). All of the patients had rapid or gradual disappearance of FMF attacks. The following changes in the laboratory parameters were observed before and after the treatment: C-reactive protein: 18.31 ± 13.58 mg/L vs 9.98 ± 11.66 mg/L, creatinine clearance: 45.27 ± 21.5 mL/min vs 50.71 ± 22.48 mL/min, and 24-hour proteinuria: 2381.8 ± 3910.4 mg vs 710.0 ± 1117.5 mg; there were no statistically significant differences on those parameters. One patient developed a reaction to injection while another showed symptoms of Cytomegalovirus pneumonia. CONCLUSION Canakinumab can be considered as a safe and efficient drug in preventing the FMF attacks in kidney transplant recipients.

Abstract
Aim/purpose: Our aim was to investigate the association between blood groups and colchicine resistance in familial Mediterranean fever (FMF) patients. METHODS This is a single-center, cross-sectional study. Between January and December 2016, 385 FMF patients were assessed by the Adult and Pediatric Rheumatology outpatient clinics and 297 patients had blood groups (ABO and Rh) results. The patients were grouped into two groups: colchicine-responsive patients (Group CR) and colchicine-unresponsive patients (Group CUR). RESULTS Patients with blood group A had 1.5-fold higher FMF compared with non-A blood group (OR: 1.50 [95% CI: 1.11-1.87]), particularly having a Rh (+) blood group (OR: 1.47 [95% CI: 1.13-1.91]). Furthermore, patients with blood group A had a better response to colchicine treatment than non-A blood group; (OR: 2.21 [95% CI: 1.15-4.27]). Patients with blood group O were prominently associated with colchicine resistance. CONCLUSION ABO blood phenogroups may be used in combination with other risk factors to identify FMF patients and patients at high risk for colchicine resistance.

Abstract
PURPOSE OF REVIEW Autoinflammatory diseases are driven by abnormal innate immune activation. In the case of inflammasomopathies, these are all attributable to activation of an inflammasome complex, nucleated by an innate immune sensor such as NLRP3. This review will focus on recent advances that have helped to elucidate the role of three other sensors (NLRP1, NLRC4 and pyrin) which can also cause inflammasomopathies. RECENT FINDINGS Mutations in pyrin (S242R or E244K) destroy an inhibitory 14-3-3 binding site and result in the newly characterised disease pyrin-associated autoinflammation with neutrophilic dermatosis (PAAND). Moreover, a separate autoinflammatory disease driven by mevalonate kinase deficiency leads to defective RhoGTPase prenylation and subsequent loss of pyrin S242R phosphorylation, suggesting a shared mechanism of disease. Other inflammasomes such as NLRP1 and NLRC4 have had novel mutations described recently, which inform about the specific domains required for activation and autoinhibition. This review covers recent advances in the study of inflammasomopathies, focussing on gene discoveries that elucidate new pathogenic mechanisms.

Abstract
Familial Mediterranean fever (FMF), the most common hereditary autoinflammatory disorder is characterized by recurrent episodes of fever, serositis, arthritis. The major long-term result is amyloidosis. Colchicine remains the principle of the treatment; it not only prevents the acute attacks but also prevents the long-term complications such as amyloidosis; 5-10% of the patients are unresponsive to treatment. Recently new therapeutic options as anti-interleukin 1 agents are successfully used for the patients who do not respond to colchicine treatment. In this study, we retrospectively evaluated 11 pediatric colchicine-resistant FMF patients who were treated with canakinumab. Three of the patients had amyloidosis and two had uveitis. Based on our results, we suggest that canakinumab may be a safe and effective therapy in patients who are resistant to colchicine and even in the patients with amyloidosis. We also suggest that canakinumab might be a safe option for the patients with uveitis.

Abstract
Colchicine is the first-line treatment for familial Mediterranean fever (FMF), preventing both inflammatory attacks as well as the development of amyloidosis in the majority of the patients. However approximately 5-10% of patients are colchicine resistant/intolerant. Side effects of colchicine are more prominent in renal transplant recipients due to interaction with immunosuppressive drugs. Anti-interleukin (IL)-1 drugs (anakinra, canakinumab and rilonacept) have emerged as the most promising drugs in the treatment of colchicine-resistant and/or intolerant FMF. There are no existing reports in the literature on canakinumab use in renal transplant recipients with FMF. We report here the efficacy and safety of canakinumab in three renal transplant recipients who achieved a complete clinical response with elimination of attacks and normalization of serum C-reactive protein (CRP) levels without significant side effects. This highlights the advantage of use of this drug in this setting, which has a better tolerability compared to anakinra.

Abstract
OBJECTIVES Children with Familial Mediterranean fever may suffer from musculoskeletal involvement, somewhat difficult to distinguish from juvenile spondyloarthritis. The association of these two diseases has been scarcely reported in children. Objective of this work was to define the association of familial Mediterranean fever and juvenile spondyloarthritis in France. METHODS Three cohorts of children with familial Mediterranean fever, juvenile spondyloarthritis, familial Mediterranean fever related juvenile spondyloarthritis, were retrospectively identified in the French reference center of auto-inflammatory diseases. Familial Mediterranean fever was defined according to Tel-Hashomer or Turkish pediatric criteria with at least one exon-10 MEFV-gene mutation. Juvenile spondyloarthritis was defined according to ILAR criteria. Patients with familial Mediterranean fever or juvenile spondyloarthritis were respectively compared to familial Mediterranean fever related juvenile spondyloarthritis patients. RESULTS Sixteen children were identified as having familial Mediterranean fever related juvenile spondyloarthritis. The male/female-ratio was 0.6, with median age at spondyloarthritis onset of 7.5years (3-16years). All carried at least one M694V variant in MEFV gene; 16.7% were HLA-B27-carriers. Compared to 83 familial Mediterranean fever patients, familial Mediterranean fever related juvenile spondyloarthritis patients had less frequently fever (P<0.01) and more frequently arthritis (P<0.05), enthesitis (P<0.001), inflammatory back pain (P<0.001), inadequate response to colchicine (P<0.05). Compared to 20 juvenile spondyloarthritis patients, familial Mediterranean fever related juvenile spondyloarthritis patients less often received non-steroidal anti-inflammatory drugs (P<0.01) and anti-tumor necrosis factor drugs (P<0.001). CONCLUSIONS Familial Mediterranean fever may be associated with typical pattern of juvenile spondyloarthritis. These patients, with less response to colchicine, should be diagnosed earlier and treated as for jSpA.

Small Intestinal Bacterial Overgrowth Affects the Responsiveness to Colchicine in Familial Mediterranean Fever. Mediators Inflamm 2017; 2017:7461426. [PMID: 29379228 PMCID: PMC5742903 DOI: 10.1155/2017/7461426] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2017] [Revised: 09/29/2017] [Accepted: 10/24/2017] [Indexed: 02/07/2023] Open
Abstract
Objective Familial Mediterranean fever (FMF) is an autosomal recessive disease due to a MEFV gene mutation. Since Helicobacter pylori infection has been described to increase the severity and frequency of FMF attacks, we evaluate if overgrowth of small intestinal bacterial (SIBO), associated with a release of bacterial products, can affect the response to colchicine in FMF patients poorly responsive to colchicine. Methods We revised our Periodic Fever Centre database to detect FMF patients who were poorly responsive to colchicine, without a well-defined cause of drug resistance. They were evaluated for SIBO presence, then treated with decontamination therapy. Results Among 223 FMF patients, 49 subjects show colchicine resistance, and no other known causes of colchicine unresponsiveness has been found in 25 patients. All 25 patients underwent glucose breath test; 20 (80%) of them were positive, thus affected by SIBO. After a successful decontamination treatment, 11 patients (55%) did not show FMF attacks during the following three months (p < 0.01), while 9 of them revealed a significant reduction of the number of attacks compared to three months before (p < 0.01). Conclusion The SIBO eradication improves laboratory and clinical features of FMF patients. Thus, patients with unresponsiveness to colchicine treatment should be investigated for SIBO.

Abstract
Objective Familial Mediterranean fever (FMF) is an autosomal recessive disease characterized by episodic and chronic inflammation that may lead to both accelerated coronary atherosclerosis and cardiac AA amyloidosis. We hypothesized that late ventricular potentials (LPs), an established electrocardiographic susceptibility marker of ventricular arrhythmias, will be more common in FMF than in the adjusted normal population due to these two types of inflammation-associated cardiac effects. Therefore, we aimed to evaluate the occurrence of LPs in FMF patients with and without amyloidosis. Material and Methods Signal-averaged electrocardiography was performed in consecutive patients with FMF using the Frank corrected orthogonal lead system. At least 200 consecutive beats were digitally recorded and averaged, and the presence of LPs was determined according to acceptable thresholds. Results There were 54 patients with colchicine-treated FMF, of whom 14 had biopsy-proven AA amyloidosis. None of the uncomplicated FMF patients and 2 of the 14 FMF amyloidosis patients had abnormal or borderline LPs. Conclusion Based on LPs as a susceptibility marker for arrhythmia, FMF patients, including the large majority of FMF patients with amyloidosis, are seemingly not at an increased risk to develop arrhythmias.

Abstract
Background Colchicine is the standard treatment for familial Mediterranean fever (FMF), preventing attacks and inflammatory complications. True resistance is rare and yet not clearly defined. We evaluated physicians’ definition of colchicine resistance and report how they manage it. Patients and methods We recruited patients with a clinical diagnosis of FMF, one exon-10 Mediterranean fever (MEFV) gene mutation and considered resistant to colchicine, via networks of expert physicians. Clinical, biological characteristics and information about colchicine treatment (dose adjustment, compliance) were collected. The severity of FMF was assessed by the Tel Hashomer criteria. Results We included 51 patients, most females (55%), mean age 34 ± 23.1 years years (range 4.7–86.3). Overall, 58% (27/47) patients had homozygous M694 MEFV gene mutations. Seventeen of 42 patients (40%) declared full adherence to colchicine treatment, greater for children (48%) than adults (22%). Physicians considered colchicine resistance with > 6 attacks/year (n = 21/51, 42%), > 4 attacks in the last 6 months (n = 13/51, 26%), persistent inflammation (n = 23/51, 45%), renal amyloidosis in (n = 6/28, 22%) of adult patients and intolerance to an increase in colchicine dose (n = 10/51, 19%), and other reasons (n = 13/51, 23%), including chronic arthralgia (n = 6/51, 12%). Interleukin 1–targeting drugs represented the only alternative treatments in addition to daily colchicine. Conclusion Resistance to colchicine is rare (<10% of patients) and mostly observed in severe MEFV genotypes. The main reasons for physicians assessing resistance were severe clinical symptoms, persistent subclinical inflammation, and secondary amyloidosis. Low adherence to colchicine treatment is a key component of resistance.

Abstract
INTRODUCTION Familial Mediterranean fever (FMF) is an autosomal recessive disease characterized by self-limited recurrent attacks of fever and serositis. Patients may develop renal amyloidosis. Colchicine prevents attacks and renal amyloidosis. Five to 10 % of the patients with FMF are resistant or intolerant to colchicine. CASE DESCRIPTION Herein, we reported our experience with clinical-laboratory features and treatment responses of a pediatric FMF patient with amyloidosis treated with canakinumab. We observed a significant decrease in proteinuria and increase growth in the patient. DISCUSSION AND EVALUATION The most serious complication of FMF is the development of AA type amyloidosis which is characterized by proteinuria. Colchicine is the prototype drug that decreases production of amyloidogenic precursor protein. Occasionally, colchicine inadequate patient is observed, as in our case. Canakinumab is a human anti-IL-1β monoclonal antibody. Previously, canakinumab efficacy were shown in a limited number of studies. CONCLUSIONS Our data, though limited to only one patient, emphasize that therapeutic intervention with canakinumab seems to be improve kidney function in colchicine-resistant FMF with renal amyloidosis.

Abstract
Familial Mediterranean fever (FMF) is the most common monogenic autoinflammatory disease worldwide. It is caused by mutations in the inflammasome adaptor Pyrin, but how FMF mutations alter signaling in FMF patients is unknown. Herein, we establish Clostridium difficile and its enterotoxin A (TcdA) as Pyrin-activating agents and show that wild-type and FMF Pyrin are differentially controlled by microtubules. Diverse microtubule assembly inhibitors prevented Pyrin-mediated caspase-1 activation and secretion of IL-1β and IL-18 from mouse macrophages and human peripheral blood mononuclear cells (PBMCs). Remarkably, Pyrin inflammasome activation persisted upon microtubule disassembly in PBMCs of FMF patients but not in cells of patients afflicted with other autoinflammatory diseases. We further demonstrate that microtubules control Pyrin activation downstream of Pyrin dephosphorylation and that FMF mutations enable microtubule-independent assembly of apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) micrometer-sized perinuclear structures (specks). The discovery that Pyrin mutations remove the obligatory requirement for microtubules in inflammasome activation provides a conceptual framework for understanding FMF and enables immunological screening of FMF mutations.
