To the Editor: We thank Brumage and colleagues1 for their commentary on our case report of an open burn pit (OBP)–exposed veteran.2 The authors highlight the nuances involved in the OBP exposure, its relationship to medical comorbidities, and their varied clinical presentation. We agree with the authors on the complexity of clinical presentation in this patient cohort, the lack of current evidence linking veterans’ deployment exposures to an increased risk of contracting COVID-19, and that reliable resources should be used to allay veteran’s concerns.
The Veterans Affairs (VA) Airborne Hazards Open Burn Pit Registry (AHOBPR) is a great resource for veterans to document their open burn pit exposure and health problems.3 However, by the end of fiscal year 2020, only 232,849 veterans and service members had completed the questionnaire from an estimated 3 million of those exposed.3 Much work is needed to reduce hesitancy to enroll in the registry. Most recently, the Under Secretary for Health with the Department of Veterans Affairs, Richard A. Stone, MD, sent an open letter to the Veterans Health Administration encouraging enrollment in the AHOBPR. While such efforts are underway, clinicians across the VA system grapple with veterans presenting with unexplained respiratory, metabolic, neurologic, and psychiatric symptoms.
In summary, the long-term effects of burn pit pollution on veterans’ health are largely unknown. There is some evidence suggesting that burn pit exposure may have caused bodily accumulation of heavy metals, consequent genetic and epigenetic changes, and long-term health problems.4–6 Carefully designed studies are needed to establish the relationship between burn pit exposure and potential adverse health outcomes and to uncover novel molecular biomarkers for exposure and diseases. We expect that close working relationships between clinical researchers in the field and the VA office of Post Deployment Health Services and the Post-9/11 Era Environmental Health Program will lead to better characterization of the medical comorbidities and biological consequences of OBP exposure.
