Acute Intermittent Porphyria Triggered by COVID‐19 Mimicking Guillain–Barré Syndrome: A Diagnostic Challenge

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Acute intermittent porphyria (AIP) is a rare heme biosynthesis disorder in which the accumulation of neurotoxic porphyrin precursors precipitates neurovisceral attacks. Intercurrent infections, including coronavirus disease 2019 (COVID‐19), may trigger or exacerbate AIP and complicate diagnosis, as clinical manifestations can resemble those of
