The case of a 16-year-old girl with recurrent acute intermittent porphyria (AIP) attacks who saw her symptoms ease after she started treatment with Givlaari (givosiran) has been reported in the U.S. The injectable therapy in the U.S. is approved only for adults with acute forms of porphyria, unlike…
The dosing of Givlaari (givosiran) may be personalized for people with acute intermittent porphyria (AIP), who are in stable condition after one year of treatment. That’s according to a recent study that described the cases of three women for whom treatment normalized the levels of delta-aminolevulinic acid (ALA),…
By combing through a database from the U.S. Food and Drug Administration (FDA), scientists in China have compiled a list of more than 50 medications that can trigger porphyria attacks. Their findings were reported in the study, “Drug-associated porphyria: a pharmacovigilance study,” published in the Orphanet Journal…
Givlaari (givosiran) safely led to a complete resolution of annual attacks in people with acute hepatic porphyria (AHP), according to real-world data from a case series study in Italy. Long-term treatment also led to sustained reductions in key markers of AHP, along with gains in physical function. A trend for…
Scenesse (afamelanotide) increases the time people with erythropoietic protoporphyria (EPP) or X-linked protoporphyria (XLP), two types of porphyria, can spend in the sun without pain, which may help improve their quality of life, a study has found. The study, “Afamelanotide for Treatment of the Protoporphyrias: Impact on…
A study in Germany found that people with acute porphyria had significant healthcare needs and a higher number of comorbidities (other medical conditions) than the country’s general publication, resulting in increased use of the healthcare system. The findings “highlight the need for healthcare strategies and policies tailored to the…
Children with erythropoietic protoporphyria (EPP) — who have severe skin hypersensitivity to sunlight — experience “markedly reduced” physical and social quality of life compared with healthy youngsters, and even relative to adults with the condition, according to a study done in the Netherlands and Belgium. “Ensuring treatment availability for…
Blood levels of neurofilament light (NfL), a marker of nerve cell damage, are 68 times higher during an acute attack in people with acute hepatic porphyria (AHP) than the levels seen in healthy adults, a recent study reported. NfL levels were elevated in patients with sporadic or recurrent porphyria…
A new artificial intelligence (AI) algorithm may help reduce the time it takes to diagnose acute hepatic porphyria (AHP) and other rare diseases. That’s according to a study reporting that models using the AI algorithm “could identify 71% of [AHP] cases earlier than their…
Oral iron supplements may help people with erythropoietic protoporphyria (EPP) build back their iron reserves and increase the levels of hemoglobin — the iron-containing protein that carries oxygen in red blood cells — a small study in Denmark suggests. However, even when taken at small doses over a short…
