The pyrin inflammasome acts as a guard of RhoA GTPases and is central to immune defenses against RhoA-manipulating pathogens. Pyrin activation proceeds in two steps. Yet, the second step is still poorly understood.

Etiocholanolone (5beta-androstan-3alpha-ol-17-one; designated E) is one of the major products of metabolism of testosterone and androstenedione (androst-4-ene-3,17-dione) in many mammalian species, including humans. E and several other 5beta-reduced steroids have been found to induce fever in humans. The pyrogenic effect of these steroids has been shown to be due to the release of interleukin-1 (IL-1) from the leukocytes that are mobilized in response to the steroid injections.

A 26-year-old female was admitted to our hospital on December 4, 1992, because of recurrent fever. She had experienced recurrent fever of over 38 degrees C, occurring at irregular intervals 4-6 times a year with chest or abdominal pain, since the age of 19. After delivery of a baby at the age of 25, her symptoms had increased to once a week.

It is widely known that the clearance of drugs is often compromised during episodes of infectious disease via a down-regulation of cytochrome P450 (P450) at a pre-translational step in enzyme synthesis. Etiocholanolone (ETC), a potent inflammatory agent, induces fever in humans and causes a decrease in the clearance of certain drugs that are metabolized by P450. On this basis it is widely believed that the fever per se rather than the immune modulation that occurs during infections may have a major role in depression of microsomal P450 enzymes during viral infections in humans.
