Summary

Despite high chloramphenicol sales in Hong Kong, aplastic anemia rates were lower than in Western countries. Further prospective studies are recommended to evaluate the drug

Area of Science:

  • Pharmacology
  • Public Health
  • Hematology

Background:

  • Chloramphenicol is a broad-spectrum antibiotic.
  • High per capita sales of chloramphenicol in Hong Kong suggest extensive community use.
  • Aplastic anemia is a serious adverse effect associated with chloramphenicol.

Purpose of the Study:

  • To compare the incidence of aplastic anemia in Hong Kong with Western countries.
  • To evaluate the risk of aplastic anemia associated with widespread chloramphenicol use.

Main Methods:

  • Comparative analysis of sales data and mortality rates.
  • Review of available epidemiological evidence on aplastic anemia incidence.

Main Results:

  • Hong Kong had significantly higher per capita chloramphenicol sales (11-442 fold) compared to Western countries.

  • The certified death rate from aplastic anemia in Hong Kong (0.4/1000 deaths) was lower than in England and Wales (1.0/1000 deaths).
  • No evidence indicated an excessive incidence of aplastic anemia among Hong Kong residents.

    • Conclusions:

    • The observed lower aplastic anemia death rate in Hong Kong, despite high chloramphenicol exposure, challenges the presumed high risk.
    • Prospective investigations are warranted in populations with widespread chloramphenicol use to accurately assess aplastic anemia risks.
