coproporphyrin

coproporphyrin

 [kop″ro-por´fĭ-rin]
a porphyrin occurring as several isomers; the III isomer, an intermediate in heme biosynthesis, is excreted in the feces and urine in hereditary coproporphyria and variegate porphyria; the I isomer, a side product, is excreted in the feces and urine in congenital erythropoietic porphyria.

(kop'rō-pōr'fi-rin),
One of two porphyrin compounds found normally in feces as a decomposition product of bilirubin (hence, from hemoglobin); certain corproporphyrins are elevated in certain porphyrias.

Twenty-four-hour urinary levels of uroporphyrin and coproporphyrin were raised.
In porphyrin testing, uroporphyrin is an indicator for aluminum, coproporphyrin for lead, and precoproporphyrin for mercury.
coproporphyrin activity is also increased due to depression of coproporphyrin oxidase enzyme.

The patient had elevated levels of total plasma porphyrin, uroporphyrin, and heptacarboxylporphyrin and hexacarboxylporphyrin; she had normal levels of pentacarboxylporphyrin, coproporphyrin I, and coproporphyrin II.

This is related to the overproduction of in-vivo of uroporphyrin, protoporphyrin, coproporphyrin and their precursors.
It results in an increase in uroporphyrin I and coproporphyrin I in plasma, red blood cells, urine, feces, and in different tissues.
Tests for detection of porphyrins in the blood, urine and stool were undertaken by the method of Haining et al.2 Presence of uroporphyrin (+++) and coproporphyrin (+) in the urine was detected by the development of bright red fluorescence under ultraviolet (UV) trans-illuminator, which occurs when concentration of porphyrins is greater than 10 times normal.3 Similarly treated normal urine samples served as controls which showed no fluorescence under UV light.
