To the Editor: Issues relating to clinical
trials in developing countries have been debated in different forums.1- 3 We have identified
an additional aspect that relates to the moral duties that researchers should
address after the termination of a clinical trial.4
To illustrate this point, we will describe our experience with a clinical
trial in which we participated between 1993 and 1998.5
The 181 participants at our site in Mexico City received benefits during the
trial that included access to primary care, periodic measurement of CD4 cell
counts and viral load counts, referral to secondary clinical care, and psychological
support. Because collaboration was established with a nongovernmental organization,
community network support also was provided. Procedures were reviewed and
approved by the appropriate local and international review boards and all
patients provided written informed consent.
