Meso-2,3-dimercaptosuccinic acid (DMSA, or succimer) is an oral chelating agent for heavy-metal poisoning. While studying the urinary elimination of unaltered DMSA, altered DMSA (i.e., its mixed disulfides), and lead in children with lead poisoning, we observed a pattern of urinary drug elimination after meals suggestive of enterohepatic circulation. The excretion of lead in urine patterned the...

PURPOSE This study assessed whether (99m)technetium dimercaptosuccinic acid (DMSA) scintigraphy used for the assessment of renal sequelae after febrile urinary tract infection (UTI) has any prognostic value for outcome measurement of vesicoureteral reflux (VUR) by retrospectively evaluating the correlation between abnormal DMSA scintigraphy results and persistence of VUR in children with febril...

BACKGROUND 99mTc-dimercaptosuccinic acid (DMSA) scan is the golden standard for the diagnosis of acute pyelonephritis and renal scaring. We investigated the use of acute phase DMSA scan in infants presented promptly to the hospital because of the first episode of their febrile urinary tract infection (UTI). METHODS Ninety-eight infants with microbiologically confirmed first episode of febrile...

BACKGROUND The lead mobilization test reflects the mobilizable and likely toxicologically active fraction of the lead body burden. We propose a safe and convenient protocol for this test, to assess concomitant copper and zinc excretion and to determine the size of the chelatable lead pool in nonoccupationally exposed adults. METHODS The study population included 80 white adults: 40 controls [...

In this study an attempt has been made to examine the efficacy of meso-2,3-dimercaptosuccinic acid (DMSA) using galactosylated liposomes as carriers for mobilization of cadmium from the body of mice preexposed to cadmium chloride (0.005 mmoles/kg intraperitoneally daily for 4 days). Cadmium-exposed mice after a rest period of 8 weeks were administered DMSA intravenously, two injections 15 micro...

© 2008 Elsevier. All rights reserved. The pentavalent Tc-99m dimercaptosuccinic acid (Tc99m (V) DMSA, Tc(V)-DMSA) radiotracer has become more widely used. The accumulation of Tc(V)-DMSA in tumors was first reported in 1981 [1], and this tracer has subsequently been shown to localize in a variety of tumors [2,3]. Tc(V)-DMSA has also been used to depict abscesses and other inflammatory lesions [4...
