The number of deaths or acute attacks in women with acute hepatic porphyria (AHP) that required hospitalization decreased significantly since 1980, although more than half of them still reported some acute symptoms, according to a natural history study in Finland. The life expectancy for women with AHP…
It’s been nearly a year since the EveryLife Foundation for Rare Diseases released its expansive report finding the total economic burden of rare disorders in the U.S. to be nearly $1 trillion.
Almost all people with severe, recurrent acute intermittent porphyria (AIP) were free from symptomatic attacks after treatment with Givlaari (givosiran), a small real-world study showed.
