Chronic aseptic meningitis may cause intracranial pressure to increase, resulting in hydrocephalus, brain atrophy and chronic papilledema (Fig. 3). the pivotal role of Cryopyrin in the control of Caspase-1 activation and the massive secretion of active IL-1 observed in cryopyrin-mutated individuals, anti-IL1 treatment represents the standard therapy. == Conclusion == Prognosis of CINCA/NOMID syndrome has been changed by the availability of anti-IL1 drugs. Nowadays, the use of anti-IL-1 drugs has sensibly reduced the risk of developing main complications such as severe intellectual disability, hearing-loss and amyloidosis, if treatment is started early on. Keywords: Autoinflammation, Cryopyrinopathies, Urticarial rash, Aseptic meningitis, Hearing loss, IL-1 == Background == Cryopyrin-associated periodic syndromes (CAPS) are inherited autoinflammatory conditions characterized by chronic systemic inflammation due to an abnormal regulation of the innate immune system. Three diseases of rising severity belong to this group: Familial Cold Autoinflammatory Syndrome (FCAS), Muckle-Wells syndrome (MWS) and Chronic Infantile Neurological Cutaneous and Articular (CINCA, or Neonatal-Onset Multisystem Inflammatory Disease, NOMID), with the latter being the most severe form (??)-BI-D of CAPS spectrum. Disease onset usually occurs within the first hours/days of life and it is characterized by intermittent fever (that may be of low grade or even absent), urticarial rash and persistent elevation of acute phase reactants. A neurological involvement featured by chronic aseptic meningitis and papilledema is usually present at disease presentation and may (??)-BI-D lead to brain atrophy, severe intellectual disability and hearing loss. Hypertrophic arthropathy with contractures and bone deformity (frontal bossing, patellar overgrowth) is also typical of this form. == Disease name/synonyms == Chronic infantile neurological cutaneous and articular (CINCA) syndrome is also called Neonatal onset multisystemic inflammatory disease (NOMID), Infantile-onset multisystem inflammatory disease (IOMID) and Prieur-Griscelli syndrome (OMIM 607115). == Definition and classification == CINCA/NOMID syndrome is the prototype of an inherited autoinflammatory disorder due to mutation of a gene encoding the NLPR3 (or cryopyrin) protein, which is involved in the activation of the inflammatory response. It belongs to the group of the so-called inflammasome-pathies, together with other conditions associated to mutations of genes that are members of the same protein family (NLRP12, NLRC4, NLRP12). == Epidemiology == It is estimated that globally the whole spectrum of CAPS has a prevalence of 12 cases in every 1 million [1] and 360, 000 [2] people in the US and France, respectively. According to a prospective surveillance of children with CAPS performed in Germany during a time period of 3 years by Lainka et al., the incidence of CAPS in Germany corresponds to 27 newly diagnosed patients 16 years per year [3]. == Clinical description == CINCA/NOMID syndrome represents the most severe phenotype in the context of the clinical spectrum of CAPS (Table1). == Table 1 . == Cryopyrin associated periodic syndrome (CAPS): main clinical features In a recent study by Levy et al. [4] the whole spectrum of CAPS in adult and pediatric patients has been described in a Rabbit Polyclonal to KITH_VZV7 large series of 136 patients enrolled in the Eurofever International Registry. The median onset age was 0. 8 years (range 0. 15) while the median age at diagnosis was 15 years (range 536) with a mean delay of diagnosis of 14 years. Seventy-eight patients (57%) had (??)-BI-D a chronic course with symptoms almost daily, whereas fifty-eight (43%) experienced only acute episodes. Fever, skin rash and musculoskeletal involvement were the most prevalent features (observed in 84, 97 and 86% of patients, respectively) and were observed in all the 3 diseases (FCAS, MWS and CINCA/NOMID). In general, CINCA/NOMID children present during the first days of life with a chronic urticarial rash associated to persistent low-grade fever and sustained elevation of acute phase reactants. The rash is non-pruritic and it changes distribution during the day, without vasculitic alterations (Fig. 1). == Fig. 1 . == Urticarial rash of CAPS patient Patients display a typical facies, featured by frontal bossing, large cephalic perimeter and saddle-back nose (Fig. 2). == Fig. 2 . == Typical CINCA/NOMID facies featured by frontal bossing, large cephalic perimeter and saddle-back nose If untreated, these patients develop (??)-BI-D permanent CNS damages as consequence of chronic inflammation [5]. Chronic aseptic meningitis may cause intracranial pressure to increase, resulting in hydrocephalus, brain atrophy and chronic papilledema (Fig. 3). Neurological symptoms typical of CINCA/NOMID are characterized by chronic irritability, intellectual disability, headache, early morning nausea, vomiting and, rarely, seizures. In the Eurovefer registry the most frequent severe neurological.
