Excretion of Porphyrin and Porphyrin Precursor during Ethylene Oxide Inhalation

Comparative effects of glycerol and dextrose on porphyrin precursor excretion in acute intermittent porphyria.

The effects of dietary manipulations on excretion of the porphyrin precursors, delta-aminolevulinic acid (ALA), and porphobilinogen (PBG) were studied in eight patients with acute intermittent porphyria. Three diet periods of 9-17 days comprised each study. In each patient, a "baseline" protein, fat, and carbohydrate intake was kept constant throughout. In addition, during the first diet period...

Urinary porphyrin excretion in hepatitis C infection.

A high prevalence of hepatitis C virus infection in porphyria cutanea tarda in some populations suggests a close link between viral hepatitis and alteration of porphyrin metabolism. Moreover, there is evidence of a role of porphyrinopathies in hepatocarcinogenesis. The aim of our study was to obtain data on the prevalence and patterns of heme metabolism alterations in patients with chronic hepa...

Urinary Porphyrin Excretion in Neurotypical and Autistic Children

BACKGROUND Increased urinary concentrations of pentacarboxyl-, precopro- and copro-porphyrins have been associated with prolonged mercury (Hg) exposure in adults, and comparable increases have been attributed to Hg exposure in children with autism (AU). OBJECTIVES This study was designed to measure and compare urinary porphyrin concentrations in neurotypical (NT) children and same-age childre...
