Recovery from deafness in a patient with Muckle-Wells syndrome treated with anakinra.

Muckle-Wells syndrome (MWS) is a dominantly inherited autoinflammatory disease characterized by rashes, fever, arthralgia, sensorineural deafness, and the possible development of systemic AA amyloidosis. We used anakinra to treat a 22-year-old patient with MWS who had deafness and a high serum level of C-reactive protein (CRP). Following treatment with anakinra, the patient's CRP level normalized, and she recovered from deafness. The fact that this occurrence has never been previously reported strengthens the role of anakinra in MWS but also raises new questions about the physiopathology of such deafness.

Amyloidosis and auto-inflammatory syndromes.

Amyloidosis remains currently a severe potential complication of many chronic inflammatory disorders. It is not exactly know why some patients develop a progressive amyloidosis, whereas others do not although latent deposits may be present. A permanent acute phase response, ideally evaluated with serial measurement of serum protein SAA, the precursor of the AA protein deposited in tissues, seems to be a prerequisite to the development of inflammatory (AA) amyloidosis. Genetic factors have however been recently emphasized. Among persistent or emerging causes of AA amyloidosis, hereditary periodic fever syndromes also known as auto-inflammatory syndromes are a group of diseases characterised by intermittent bouts of clinical inflammation with focal organ involvement mainly: abdomen, musculoskeletal system and skin. The most frequent is familial Mediterranean fever which affects patients of Mediterranean descent all over the world. Three other types have been recently clinically as well as genetically characterised. A thorough diagnosis is warranted, as clinical and therapeutic management is specific for each of these diseases.

Intrafamilial variable phenotypic expression of a CIAS1 mutation: from Muckle-Wells to chronic infantile neurological cutaneous and articular syndrome.

Among hereditary inflammatory disorders, Muckle-Wells syndrome, chronic infantile neurological cutaneous and articular syndrome (CINCA), and familial cold urticaria have recently been shown to be caused by dominantly inherited mutations in the CIAS1 gene. Reports suggest that these 3 diseases result from distinct missense mutations, with very few overlapping symptoms. We describe a French family presenting an intrafamilial overlapping clinical phenotype of CINCA and Muckle-Wells syndrome, caused by a mutation in CIAS1 gene. Clinical and genetic observations suggest that Muckle-Wells syndrome, CINCA, and familial cold urticaria are various phenotypic expressions of the same disease.

[Hereditary intermittant fever].

UNLABELLED: Other than familial mediterranean fever: Four hereditary diseases presenting in the form of intermittent inflammatory flares are now recognized and have been characterised clinically and genetically. At the head of this group is Familial Mediterranean Fever (FMF), which affects thousands of patients originating from the Mediterranean area. However the familial Mediterranean Fever is no longer the only recurrent hereditary inflammatory disease. Three other entities have now been clearly defined: intermittent fever secondary to mutations in the type 1A Tumour Necrosis Factor receptor (TNF), of dominant autosomic genetic transmission, the hyperimmunoglobulinemia D syndrome and an entity regrouping the Muckle Wells syndrome, familial cold-induced urticaria, and the Chronic Infantile Neurological Cutaneous and Articular (CINCA) syndrome. IN PRACTICE: Because they require specific management and treatment, precise diagnosis of these entities is crucial.

Infevers: an evolving mutation database for auto-inflammatory syndromes.

The Infevers database (http://fmf.igh.cnrs.fr/infevers/) was established in 2002 to provide investigators with access to a central source of information about all sequence variants associated with periodic fevers: Familial Mediterranean fever (FMF), TNF Receptor Associated Periodic Syndrome (TRAPS), Hyper IgD Syndrome (HIDS), Familial Cold Autoinflammatory Syndrome/Muckle-Wells Syndrome/Chronic Infantile Neurological Cutaneous and Articular Syndrome (FCAS/MWS/CINCA). The prototype of this group of disorders is FMF, a recessive disease characterized by recurrent bouts of unexplained inflammation. FMF is the pivotal member of an expanding family of autoinflammatory disorders, a new term coined to describe illnesses resulting from a defect of the innate immune response. Therefore, we decided to extend the Infevers database to genes connected with autoinflammatory diseases. We present here the biological content of the Infevers database, including the introduction of two new entries: Crohn/Blau and Pyogenic sterile arthritis, pyoderma gangrenosum and acne (PAPA syndrome). Infevers has a range of query capabilities, allowing for simple or complex interrogation of the database. Currently, the database contains 291 sequence variants in related genes (MEFV, TNFRSF1A, MVK, CARD15, PSTPIP1, and CIAS1), consisting of published data and personal communications, which has revealed or refined the preferential mutational sites for each gene. This database will continue to evolve in its content and to improve in its presentation.

Familial reciprocal translocation t(7;16) associated with maternal uniparental disomy 7 in a Silver-Russell patient.

We present the case of a maternal heterodisomy for chromosome 7 in the daughter of a t(7;16)(q21;q24) reciprocal translocation carrier. The proband was referred to the hospital for growth retardation and minor facial dysmorphism without mental retardation. A diagnosis of Silver-Russell syndrome was suspected. Chromosomal analysis documented a 46,XX,t(7;16)(q21;q24)mat chromosome pattern. Microsatellite analysis showed a normal biparental inheritance of chromosome 16 but a maternal heterodisomy of chromosome 7. Occurrence of uniparental disomy (UPD) is a well-recognized consequence of chromosomal abnormalities that increase the rate of meiotic nondisjunction, mainly Robertsonian translocations and supernumerary chromosomes. Although reciprocal translocations should, theoretically, be also at increased risk of UPD, only three cases have been reported so far. However, because the association between uniparental disomy and reciprocal translocation may exist with an underestimated frequency, prenatal diagnosis is recommended when clinically relevant chromosomes for UPD are involved.

New mutations of CIAS1 that are responsible for Muckle-Wells syndrome and familial cold urticaria: a novel mutation underlies both syndromes.

Mutations of CIAS1 have recently been shown to underlie familial cold urticaria (FCU) and Muckle-Wells syndrome (MWS), in three families and one family, respectively. These rare autosomal dominant diseases are both characterized by recurrent inflammatory crises that start in childhood and that are generally associated with fever, arthralgia, and urticaria. The presence of sensorineural deafness that occurs later in life is characteristic of MWS. Amyloidosis of the amyloidosis-associated type is the main complication of MWS and is sometimes associated with FCU. In FCU, cold exposure is the triggering factor of the inflammatory crisis. We identified CIAS1 mutations, all located in exon 3, in nine unrelated families with MWS and in three unrelated families with FCU, originating from France, England, and Algeria. Five mutations--namely, R260W, D303N, T348M, A439T, and G569R--were novel. The R260W mutation was identified in two families with MWS and in two families with FCU, of different ethnic origins, thereby demonstrating that a single CIAS1 mutation may cause both syndromes. This result indicates that modifier genes are involved in determining either a MWS or a FCU phenotype. The finding of the G569R mutation in an asymptomatic individual further emphasizes the importance of such modifier a gene (or genes) in determining the disease phenotype. Identification of this gene (or these genes) is likely to have significant therapeutic implications for these severe diseases.

[Hereditary intermittent fevers, other than familial Mediterranean fevers].

Familial Mediterranean fever is no more the sole hereditary disease characterized by recurrent inflammatory attacks. Three other main entities have now been defined, both at clinical and genetic levels: a dominant disease due to mutations of one of the tumour necrosis factor receptor, called TRAPS for tumour necrosis factor receptor associated periodic syndrome, the hyper-immuno-globulinaemia D and periodic fever syndrome (HIDS), which is a metabolic disorder and the Muckle-Wells syndrome. A thorough diagnosis of these diseases is crucial for appropriate management and treatment.

TNFRSF1A-associated periodic syndrome (TRAPS), Muckle-Wells syndrome (MWS) and renal amyloidosis.

TNFRSF1A-associated periodic syndrome (TRAPS) and Muckle-Wells syndrome (MWS) are two rare autosomal-dominant inherited periodic fever syndromes found in various populations. The genes involved in these syndromes are respectively TNFRSF1A (TNF receptor 1) and CIAS1 (a gene containing both pyrin and NBS domains). Missense mutations found in these genes are probably responsible for an improvement in function. Renal AA amyloidosis can also be observed.
