Autonomic dysfunction due to lead poisoning.
We present a case history of a 24 years old male who developed autonomic dysfunction, intestinal pseudo-obstruction and anemia due to lead poisoning. Concomitant recording of blood levels of lead and autonomic function showed a gradual decline in blood lead level (98.8 microg/dL at week 0, 56 microg/dL at week 6, and 40 microg/dL at week 52) and gradual improvement in autonomic functions. Decrease in blood lead levels with DMSA (Meso-2, 3-dimercaptosuccinic acid) therapy showed improvement in autonomic functions. At week 0, the patient had severe loss of autonomic tone and autonomic reactivity which improved at week 6. At the 52nd week, most of the autonomic parameters had normalized except for the persistence of mild loss of parasympathetic reactivity.
