Final answer:
CAPS are characterized by recurrent fevers and rash, representing a spectrum of hereditary autoinflammatory disorders that involve excessive inflammation due to genetic factors. Symptoms can be mistaken for infections or allergies but are actually due to an internal inflammatory response caused by genetic abnormalities in inflammation regulation.
Step-by-step explanation:
Cryopyrin associated periodic syndromes (CAPS) are characterized by A) Recurrent fevers and rash. They are a grouping of rare, inherited, autoinflammatory disorders that represent a spectrum of disease activity including Familial Cold Autoinflammatory Syndrome, Muckle-Wells Syndrome, and Neonatal-Onset Multisystem Inflammatory Disease. These disorders are marked by recurring episodes of fever, joint pain, and various skin manifestations. CAPS are driven by improper regulation of the inflammation process, leading to excessive release of interleukin-1 (IL-1).
The symptoms of CAPS can sometimes be mistaken for recurrent infections or allergic reactions. However, unlike allergic reactions which are typically caused by external allergens, CAPS flares are due to internal genetic factors related to inflammation regulation. These flares often manifest with the stated symptoms of fever, skin rash, as well as potential joint pain and other organ-specific issues depending upon the severity of the syndrome.
