Five years of standard treatment did not slow the progression of congenital erythropoietic porphyria (CEP) — the rarest type of porphyria, marked by severe light sensitivity — in a young man in Armenia, according to a study on the first reported case of the condition in that country. For…

Outcomes for children with congenital erythropoietic porphyria (CEP) have improved over the last few decades, and babies with CEP today are more likely to receive treatment that can improve their survival. That’s according to findings from a study, “Severe Perinatal Presentations of Günther’s Disease: Series of…

Researchers in Italy hope to help clinicians more quickly recognize acute intermittent porphyria (AIP) in their case report of a young woman who saw her condition severely worsen after years of delayed diagnosis. The woman had a history of psychiatric issues and abdominal pain, and then developed neurological symptoms,…
