Hematologic iron analyte values as an indicator of hepatic hemosiderosis in Callitrichidae.
Hepatic hemosiderosis is one of the most common postmortem findings in captive callitrichid species. Noninvasive evaluation of hematologic iron analytes has been used to diagnose hepatic iron storage disease in humans, lemurs, and bats. This study evaluated the relationship between hematologic iron analyte values (iron, ferritin, total iron binding capacity, and percent transferrin saturation) and hepatic hemosiderosis in callitrichids at the Wildlife Conservation Society's Central Park and Bronx Zoos. Results revealed that both ferritin and percent transferrin saturation levels had strong positive correlations with hepatic iron concentration (P<0.001, r=0.77, n=20; P<0.001, r=0.85, n=10, respectively). Serum iron levels positively correlated with hepatic iron concentration (P=0.06, r=0.56, n=11), but this finding was not significant. Serum total iron binding capacity did not significantly correlate with hepatic iron concentration (P=0.47, r=0.25, n=10). Both ferritin and hepatic iron concentration positively correlated with severity of hepatic iron deposition on histology (P<0.05, r=0.49, n=21; P<0.001, r=0.67, n=21, respectively). This study suggests that ferritin, serum iron concentration, and percent transferrin saturation are convenient, noninvasive, antemortem methods for assessing severity of hemosiderosis in callitrichids.
