succimer and Anemia--Hemolytic

Our objective is to present a case of symptomatic lead toxicity (plumbism) with abdominal colic and hemolytic anemia following a gunshot wound. It is a retrospective case report and the setting is in a teaching hospital in south central Los Angeles. The case report is that of a patient who presented with abdominal pain, generalized weakness, and hypertension following multiple gunshot wounds, 15 years previously. Other causes of abdominal pain and weakness--such as diabetes mellitus, alcohol abuse, pancreatitis, and substance abuse--were ruled out. Interventions included treatment with the newer oral chelating agent, Succimer (2, 3-dimercaptosuccinic acid), and subsequent surgery. The main outcome was the initial reduction in blood lead levels with improvement of symptoms. Because of a recurrent rise in the blood lead levels, the patient was again treated with Succimer and underwent surgery to remove two bullet fragments from the face. We conclude that lead toxicity should be ruled out in patients presenting with abdominal cramps and a history of a gunshot wound. Prompt therapy--including environmental intervention and chelation therapy--is mandatory, and surgical intervention may be necessary.

Because of its favorable side effects profile, the oral chelating agent dimercaptosuccinic acid is often used for treatment of lead intoxication. We report a case of a 45-year-old black male with glucose-6-phosphate dehydrogenase deficiency and a 17 year history of occupational lead exposure who developed hemolysis during treatment with dimercaptosuccinic acid for symptomatic lead intoxication.

Symptomatic lead poisoning with severe hemolytic anemia was observed in a patient with retained shot gun pellets. Surgical resection of the retained pellets and the use of a newer chelating agent, Succimer (2,3-dimercaptosuccinic acid) successfully lowered blood lead level. Hemolytic anemia was associated with deficient erythrocyte pyrimidine 5'-nucleotidase, and lowering of the lead level corrected the deficiency, suggesting that the enzyme deficiency is responsible for the hemolysis associated with lead poisoning. This case illustrates that retained lead pellets from shotgun wounds can cause severe lead poisoning.
