Lead poisoning from Asian traditional remedies in the West Midlands - report of a series of five cases

Abstract

1 Traditional remedies are an unusual, but recognised cause of lead poisoning. Only two cases have previously been reported in this country.

2 We report a series of five cases of lead poisoning due to traditional remedies in the West Midlands. All devel oped typical clinical features.

3 Blood lead and zinc protoporphyrin (ZPP) concentra tions were elevated 2-10 times the upper limit of nor mal. The remedies contained up to 60% lead by weight. One also contained traces of mercury, another arsenic, and a third aluminium and tin.

4 Confirmation of the medicines as the cause of the poi soning was made in one patient by measurement of lead isotopic ratios.

5 The present morbidity from traditional remedies may be far greater than is realised, and will continue until such time as the supply of harmful preparations can be effec tively limited. There needs to be increased awareness of their dangers amongst doctors and the communities at risk. This will best be achieved by appropriately targeted education.
