A Case of Hereditary Coproporphyria in which the Patient's Course Improved after the Discontinuation of Givosiran

Intern Med. 2024 Mar 11. doi: 10.2169/internalmedicine.3284-23. Online ahead of print.ABSTRACTHereditary coproporphyria (HCP) is caused by a partial deficiency of coproporphyrinogen oxidase during heme biosynthesis. Givosiran is approved for the treatment of acute hepatic porphyria. We herein report the case of a 47-year-old woman with HCP. Monthly givosiran administration improved her subjective symptoms and reduced her δ-aminolevulinic acid (ALA) and porphobilinogen (PBG) levels to the normal range. However, givosiran was discontinued after six months due to a decreased renal function. The patient's ALA and PBG levels remained within the normal ranges, and her HCP-related symptoms resolved more than 2 years after the discontinuation of givosiran.PMID:38462517 | DOI:10.2169/internalmedicine.3284-23
