Abstract Background Autoinflammatory diseases (AID) are a group of genetic syndromes resulting from an excessive activation of the innate immune system, caused by mutations in genes regulating the inflammatory pathways and can involve several organs. The aim of this study is to evaluate the clinical, paraclinical, epidemiogical and genetic data of Moroccan patients with confirmed AID, in order to allow a first experience of AID registry in our unit. Material We have retrospectively analyzed 30 cases of patients in our unit over a period of 13 years (between 2006 and 2019), according to inclusion criterias (recurrent fever > 3 episodes and a CRP > 40mg/L) and having excluded immune deficiency, autoimmune disease, neoplasia and infectious diseases. Results The mean age of our patients at 1st consultation was 6.9 years (with extremes ranging from 8 months to 14 years). Consanguinity was reported in 16 cases, and unknown in one case of an adopted child. The patients were classified as follows: 66% of cases with Familial Mediterranean Fever (FMF) including 1 case with a characteristic phenotype of Marshall/Periodic Fever Aphtous Pharyngitis Adenitis (PFAPA) syndrome, 16% of cases with Mevalonate Kinase Deficiency (MKD), 10% of cases with Chronic Recurrent Multifocal Osteomyelitis (CRMO), 1 patient with Familial Pustular Psoriasis (FPP) and another symptomatic patient with Muckle Wells syndrome. An association with Henoch Schonlein purpura was reported in 30% of cases and with periarteritis nodosa in 1 case in FMF patients. The mean diagnostic delay was 3 years (with extremes ranging from 1 month to 12 years). The main clinical features found in our patients included fever (83%), abdominal pain (90%), arthralgia (83%), arthritis (46%), adenopathies (40%), aphtous (30%) and other specific signs. Genetic analysis revealed that M694V was the most frequent mutation (60%), followed by A744S (15%), E148Q (10%), K695R (10%) and P369S/ R408Q (5%) in all FMF patients, and V337I found in 1 patient with MKD while the 4 others were confirmed basing on a high rate of urinary mevalonic acid. CRMO patients were confirmed by radiological and histological analysis. The case of FPP was confirmed histologically by skin biopsy and the patients with Muckle Wells and PFAPA syndroms were diagnosed basing on characteristic clinical features. Therapeutically, all FMF patients were treated with colchicine in addition of corticosteroids in 1 case of PFAPA syndrome. Patients with MKD received targeted therapy (Anakinra, Etanercept) and Ibuprofen in 1 case. CRMO patients were treated with targeted therapy and NSAIDs. The case of FPP was treated with Methotrexate combined with Etanercept and the patient with Muckel Wells Syndrome received corticosteroid therapy combined with Azathioprine and then Anakinra. The clinical and biological evolution was considered favorable in 76% of cases, partial in 13% of cases and 3 death cases were reported. Conclusion AIDs remain rare genetic syndromes whose lack of knowledge explains the late diagnostic delay. Therefore, it is necessary for any pediatrician to know how to evoke an AID in front of recurrent fever with free intervals, clinical features and inflammatory syndrome, in order to choose the optimal treatment as well as to make the genetic counseling.

The hereditary periodic fever syndromes or hereditary autoinflammatory diseases are disorders of innate immunity that mostly present in childhood and are characterized by recurrent, self-limiting, seemingly unprovoked episodes of fever and systemic inflammation that occur in the absence of autoantibody production or identifiable infection. Disorders include (1) familial Mediterranean fever (FMF), due to mutations in the gene encoding pyrin; (2) tumour necrosis factor (TNF) receptor-associated periodic syndrome (TRAPS), due to mutations in a gene for a TNF receptor; (3) mevalonate kinase deficiency and period fever (MKD), caused by mutations in the mevalonate kinase gene; and (4) the cryopyrin-associated periodic syndromes (CAPS), which include (a) familial cold urticarial syndrome, (b) Muckle–Wells syndrome, and (c) chronic infantile neurological, cutaneous, and articular syndrome. With advances in genetics, further syndromes are continually being recognized. These are all extremely rare and in the majority are only known to affect a handful of kindred or individuals. Diagnosis relies on recognition of suggestive clinical features that are almost always accompanied by a substantial acute phase response, and is supported by genetic testing. With the exception of FMF, which is a common disease in certain geographic areas, hereditary periodic fever syndromes are rare and easily overlooked in the differential diagnosis of recurrent fevers. Clinical features and management—attacks can be mild to debilitating and short to prolonged, while their most feared complication is AA amyloidosis. Effective therapies are available for some syndromes, for example: (1) FMF—daily prophylactic colchicine prevents clinical attacks and susceptibility to AA amyloidosis, (2) CAPS—treatment with anti-IL-1 agents produces rapid and often complete clinical and serological remission, and (3) TRAPS—anti-IL therapies are extremely effective.

Abstract Objective The new classification criteria for the hereditary recurrent fever (HRF) syndrome [cryopyrin-associated periodic syndrome (CAPS), TNF-α receptor-associated periodic syndrome (TRAPS), FMF and mevalonate kinase deficiency] have been published recently. These criteria define two core sets of criteria for each HRF: mixed criteria, including genetic and clinical variables, and clinical criteria, relying on clinical variables only. Our aim was to validate the criteria for HRF in an independent cohort, the JIR Cohort database, an international repository of systemic inflammatory diseases. Methods We enrolled patients with HRF, periodic fever, adenitis, pharyngitis and aphthous stomatitis syndrome (PFAPA) and syndrome of undefined recurrent fever (SURF). A score ranging from zero to two was attributed to their respective genotypes: zero (no mutation), one (non-confirmatory genotype) or two (confirmatory genotype). The criteria were applied to all patients based on genotype scoring. The treating physician’s diagnosis served as the gold standard for the determination of specificity. Results We included 455 patients. The classification criteria showed excellent specificity for CAPS and TRAPS (98% specificity each), fair specificity for FMF (88%), but poor specificity for mevalonate kinase deficiency (58%). Sub-analysis showed excellent accuracy of the mixed criteria for all four HRFs. Misclassification was mainly attributable to clinical criteria sets, with false-positive patients in all four HRF clinical criteria sets. Conclusion This study represents the final validation step of the HRF classification criteria as recommended by the ACR. Genetic data appear to be necessary to classify patients with HRF correctly.

Objective.Provisional evidence-based classification criteria for hereditary periodic fever (HPF) have been recently developed. However, no consensus on how to combine clinical criteria, laboratory tests, and results of molecular analysis has been reached. The objective of this study is to understand which variables physicians consider important for the classification of patients with HPF.Methods.Two Delphi surveys were sent to health professionals in the field of autoinflammation. In the first open survey, 124 researchers could list all the variables they consider useful for the diagnosis of each monogenic periodic fever. The variables could be of any type and each researcher could complete the survey for 1 or more diseases. In the second survey, 162 researchers were asked to select, from a list of items coming from the first survey, the 10 top variables and to rank them by assigning a score from 10 to 1.Results.The response rates to the Delphi surveys were 85% for the first session and 87% for the second. The variables selected for each disease (corresponding to the third quartile, considering the total score obtained by the variables after the second Delphi survey) were 21 for mevalonate kinase deficiency, 22 for cryopyrinopathies, 18 for familial Mediterranean fever, and 20 for tumor necrosis factor receptor–associated periodic fever syndrome. A positive genetic test reached the top rank in all the HPF.Conclusion.Our process led to the identification of those features considered the most important as candidate variables to be included in a new set of evidence-based classification criteria for HPF.

PFAPA (Periodic Fever, Aphthous Stomatitis, Pharyngitis and Adenitis) is the most common self-inflammatory disorder in children. The diagnosis of PFAPA is easy, based on Thomas criteria, and the prognosis is good. Differential diagnosis with hereditary periodic fever syndromes (Familial Mediterranean Fever, Mevalonate Kinase Deficiency, TRAPS and CAPS) should be considered only in the presence of red flags such as early onset, severe abdominal complaints, arthritis and severe rashes. Some patients may present distinct clinical entities with periodic fevers that neither meet PFAPA criteria nor hereditary periodic fever syndromes genotypes. Subjects with these “Undifferentiated Periodic Fever” may respond to glucocorticoids or colchicines or to anakinra in the most severe cases and still have an undetermined prognosis.

Mevalonate kinase deficiency (MKD) is a periodic fever syndrome. Nonsteroidal anti-inflammatory drugs, corticosteroids, and anakinra are the most common treatments. However, colchicine is considered insufficient in disease control. In this case report, we present an 8-month-old infant with an atypical presentation of MKD. She had recurrent fever episodes, diarrhea, and lethargy. Elevated mevalonic acid was not detected in the urine. However, the genetic investigation showed a novel pathogenic heterozygous c.925G&#x3e;C (p.Gly309Arg) variant and a heterozygous c.1129G&#x3e;A (p.Val377Ile) mutation in the <i>MVK</i> gene. The patient was treated with colchicine for 8 months. During treatment, no further fever episode had been observed. It should be kept in mind that mevalonic acid excretion may not be present in the urine with mild MKD. Colchicine may be a reasonable option in mild MKD patients for a longer duration of treatment due to favorable adverse event profiles.

Autoinflammatory diseases (AIDs) represent a rare and heterogeneous group of disorders characterized by recurrent episodes of inflammation and a broad range of clinical manifestations. The most common symptoms involve recurrent fevers, musculoskeletal symptoms, and serositis; however, AIDs can also lead to life-threatening complications, such as macrophage activation syndrome (MAS) and systemic AA amyloidosis. Typical monogenic periodic fever syndromes include cryopyrin-associated periodic fever syndrome (CAPS), tumor necrosis factor receptor-associated periodic syndrome (TRAPS), mevalonate kinase deficiency/hyper IgD syndrome (MKD/HIDS), and familial Mediterranean fever (FMF). However, a number of other clinical entities, such as systemic juvenile idiopathic arthritis (sJIA), adult-onset Still’s disease (AOSD), Kawasaki disease (KD) and idiopathic recurrent pericarditis (IRP), display similar phenotypical and immunological features to AIDs. All these diseases are pathophysiologicaly characterized by dysregulation of the innate immune system and the central pathogenic role is attributed to the IL-1 cytokine family (IL-1α, IL-1β, IL-1Ra, IL-18, IL-36Ra, IL-36α, IL-37, IL-36β, IL-36g, IL-38, and IL-33). Therefore, reasonable therapeutic approaches aim to inhibit these cytokines and their pathways. To date, several anti-IL-1 therapies have evolved. Each drug differs in structure, mechanism of action, efficacy for the treatment of selected diseases, and side effects. Most of the available data regarding the efficacy and safety of IL-1 inhibitors are related to anakinra, canakinumab, and rilonacept. Other promising therapeutics, such as gevokizumab, tadekinig alfa, and tranilast are currently undergoing clinical trials. In this review, we provide sophisticated and up-to-date insight into the therapeutic uses of different IL-1 inhibitors in monogenic periodic fever syndromes.

BackgroundDifferent diagnostic and classification criteria are available for hereditary recurrent fevers (HRF)—familial Mediterranean fever (FMF), tumour necrosis factor receptor-associated periodic fever syndrome (TRAPS), mevalonate kinase deficiency (MKD) and cryopyrin-associated periodic syndromes (CAPS)—and for the non-hereditary, periodic fever, aphthosis, pharyngitis and adenitis (PFAPA). We aimed to develop and validate new evidence-based classification criteria for HRF/PFAPA.MethodsStep 1: selection of clinical, laboratory and genetic candidate variables; step 2: classification of 360 random patients from the Eurofever Registry by a panel of 25 clinicians and 8 geneticists blinded to patients’ diagnosis (consensus ≥80%); step 3: statistical analysis for the selection of the best candidate classification criteria; step 4: nominal group technique consensus conference with 33 panellists for the discussion and selection of the final classification criteria; step 5: cross-sectional validation of the novel criteria.ResultsThe panellists achieved consensus to classify 281 of 360 (78%) patients (32 CAPS, 36 FMF, 56 MKD, 37 PFAPA, 39 TRAPS, 81 undefined recurrent fever). Consensus was reached for two sets of criteria for each HRF, one including genetic and clinical variables, the other with clinical variables only, plus new criteria for PFAPA. The four HRF criteria demonstrated sensitivity of 0.94–1 and specificity of 0.95–1; for PFAPA, criteria sensitivity and specificity were 0.97 and 0.93, respectively. Validation of these criteria in an independent data set of 1018 patients shows a high accuracy (from 0.81 to 0.98).ConclusionEurofever proposes a novel set of validated classification criteria for HRF and PFAPA with high sensitivity and specificity.
