Clinical Manifestations and Diagnostic Challenges in Acute Porphyrias

الملخص EN

The porphyrias are a group of disorders characterized by an enzyme deficiency in the heme biosynthetic pathway.

These can be classified into either erythropoietic or hepatic forms depending on the site of the major enzyme deficiency.

The diagnosis of acute porphyrias, however, can be very challenging due to overlapping features amongst the various types.

Initial suspicion is based on a myriad of clinical manifestations, which then are confirmed by laboratory testing where available.

Genetic testing is now also available for the different types of porphyrias, aiding in the definitive diagnosis.

Here, we present a challenging case of porphyria in a patient with end-stage renal disease and present the diagnostic challenges associated with the case and the ways forward.
