Proteasome-associated autoinflammatory syndromes
PRAAS include chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE) syndrome, Japanese autoinflammatory syndrome with lipodystrophy (JASL), joint contractures, muscular atrophy, microcytic anemia, and panniculitis-induced lipodystrophy (JMP) syndrome, and Nakajo-Nishimura syndrome (NNS).
Patients with PRAAS typically present at birth or in early infancy with periodic fever, variable skin eruptions, lipodystrophy, hepatosplenomegaly, and muscular atrophy and myositis, accompanied by anemia of chronic disease and elevated acute phase reactants (ESR, C-reactive protein [CRP]). Flares and inflammatory symptoms are typically noted by 6 months of age, and patients accumulate progressive damage from chronic inflammation during childhood.
