US President Barack Obama personally apologized on Friday to his Guatemalan counterpart for a US-led study conducted in the 1940s, in which hundreds of people in the Latin American state were deliberately infected with sexually transmitted diseases.
In a phone conversation with Guatemalan President Alvaro Colom, Obama expressed his deep regret for the experiment conducted by US public health researchers in Guatemala between 1946 and 1948, and apologized “to all those affected.”
The US president also vowed that all human medical studies conducted today would be held to exacting US and international legal and ethical standards.
“This is shocking, it’s tragic, it’s reprehensible,” White House spokesman Robert Gibbs told reporters, adding to apologies and outrage voiced by the president, US Secretary of State Hillary Clinton, US Health Secretary Kathleen Sebelius and other US officials.
In an impromptu news conference in Guatemala on Friday, Colom denounced the study as “a crime against humanity,” and said he had learned of the gruesome years-long experiment in the phone call from Clinton.
Clinton had phoned Colom on Thursday to express her personal outrage and deep regret over the “reprehensible research.”
“What happened all those years ago is a crime against humanity and the government reserves the right to lodge a formal legal complaint over it,” Colom said.
However, almost immediately, he backed off his tough rhetoric, saying: “We are aware that this is not the policy of the United States ... this happened so long ago.”
Clinton and Sebelius said in a joint statement on Friday that the study was “clearly unethical” and apologized to all those who had been affected by it.
Francis Collins, director of the National Institutes of Health (NIH), the US government body that funded the study, called it “deeply disturbing” and “an appalling example in a dark chapter in the history of medicine.”
US Senator Robert Menendez, a member of the congressional Hispanic caucus, called the experiments in Guatemala one of the “darkest moments” in US history.
“No innocent fellow human should be treated as a lab rat, no matter your nationality,” Menendez said.
The study, which was never published, came to light this year after Wellesley College professor Susan Reverby stumbled upon archived documents outlining the 1940s experiment led by controversial US public health doctor John Cutler.
Cutler and his fellow researchers enrolled people in Guatemala, including mental patients, for the study, which aimed to find out if penicillin, relatively new in the 1940s, could be used to prevent sexually transmitted diseases.
“There is no evidence study participants gave informed consent, and in fact ... the subjects were often deceived about what was being done to them,” Collins told reporters as he outlined the experiment’s most flagrant ethics violations.
Cutler, the US doctor behind the Guatemala study, was also involved in a highly controversial study known as the Tuskegee Experiment in which between 1932 and 1972 hundreds of African American men with late-stage syphilis were observed and given no remedial treatment.
Initially, the researchers infected female commercial sex workers with gonorrhea or syphilis, and then allowed them to have unprotected sex with soldiers or prison inmates.
“When few of these men became infected, the research approach changed to direct inoculation of soldiers, prisoners and mental hospital patients,” background documents on the study show.
