People with acute hepatic porphyria (AHP) having recurrent attacks are burdened with chronic symptoms between those attacks, according to data from the natural history EXPLORE study. High disease burden was also observed in patients having fewer porphyria attacks — less than three in the absence of preventive treatment for…

A total of 30 patient advocacy groups working to further understanding and the needs of people living with rare diseases have been selected to receive a Horizon Therapeutics‘ #RAREis Global Advocate Grant. Winners of this year’s inaugural awards are spread across nine countries and represent a total of 29 rare…

A large proportion of people with acute intermittent porphyria (AIP) may still be undiagnosed in China, according to a recent study — and without a proper diagnosis, they’re not receiving needed treatment, researchers say. “More nationwide epidemiological surveys and study of the prevalence rate of AIP patients in China are…

A report has described for the first time the case of a patient having an acute intermittent porphyria (AIP) attack following treatment with oseltamivir, an oral antiviral medication commonly prescribed for treating the flu. The report, “Acute intermittent porphyria: is oseltamivir safe in these patients?,” was published in…

A previously identified mutation in the PPOX gene in a Moroccan Jewish population may cause variegate porphyria by impairing the correct 3D folding of the PPOX enzyme. Incorrectly folded, the activity of the mutated enzyme was severely impaired. The study, “Molecular characterization of a novel His333Arg variant of…
