NIH cancels Havana syndrome research citing unethical coercion of participants
By published
The National Institutes of Health announced on Friday that it will cease its investigation into what is commonly referred to as Havana syndrome, a perplexing ailment reported by various diplomats, soldiers, and intelligence personnel who have experienced sudden and severe symptoms of unknown origin. The NIH's decision to halt the research was made "out of an abundance of caution" following an internal review that revealed instances of coercion in participant recruitment.
The agency clarified that it was not responsible for the coercion, but did not specify who may have pressured individuals to take part in the study. The NIH emphasized that voluntary consent is a cornerstone of ethical research practices.
Some individuals who reported their illnesses previously alleged that certain agencies compelled them to participate in the research as a condition for receiving medical care. A representative from one of these agencies stated that they take any allegations of coercion seriously and have fully cooperated with the NIH's investigation, offering access to any requested information. The Inspector General is aware of the NIH's findings and the related allegations.
Marc Polymeropoulos, a former officer who has experienced health issues, expressed frustration, stating that he and others were treated like "lab rats" before receiving treatment at Walter Reed, deeming such practices unethical and immoral. He has advocated for those affected by what the U.S. government categorizes as "anomalous health incidents" and suggested that participation in the research was mandated by senior officials.
In March, the agency denied that participation was compulsory. The agency did not respond to requests for comment on Friday.
Ethicists note that forced participation in research studies is considered highly unethical and is exceedingly rare. The NIH informed that it has communicated its decision to discontinue the research to JAMA, the medical journal that published two studies stemming from this investigation in March. JAMA has not provided further comments.
While the NIH is halting this research, it clarified that this decision does not alter the findings of the studies. Despite numerous reports of symptoms from federal employees, neither study identified any definitive causes for the health issues.
In one study, NIH researchers examined the brains of individuals believed to be suffering from Havana syndrome and found no consistent evidence of brain damage, nor significant differences when compared to a healthy control group. The second study involved a series of tests on 86 U.S. government personnel and their family members who reported symptoms, comparing them to 30 individuals in similar roles without such symptoms. The results indicated that both groups were largely similar across various clinical and biomarker assessments.
In an editorial accompanying the studies in JAMA, Dr. David Relman, a microbiology and immunology professor at Stanford who has previously investigated this patient group, cautioned against hastily concluding that "nothing serious" occurred in these cases. He noted that other research has indicated brain abnormalities, and the same applies to the second study. Due to the variability of the condition's presentation, he argued that there are no specific tests capable of definitively diagnosing the issue.
Relman advocated for the development of new, sensitive, standardized, and non-invasive tests to assess nervous system function, particularly focusing on the vestibular system, as well as more precise blood markers for various types of cellular injury.
The origins and causes of this illness remain frustratingly unclear to both the intelligence and medical communities investigating it. The term Havana syndrome originated in late 2016 when American diplomats in Cuba reported symptoms resembling head trauma, such as severe headaches and dizziness. Since then, over 1,500 cases have been documented among U.S. personnel in 96 countries, according to officials last year.
There has been ongoing speculation regarding the possibility of a novel weapon being responsible for these ailments; however, the U.S. intelligence community stated last year that it could not connect any cases to a foreign adversary, making it improbable that the unexplained illness resulted from a targeted attack by an enemy of the United States.
