 Episode 2: When to get your blood tested for PFAS. https://vimeo.com/1055803097 Download the Ambassador Slides HANDOUT to share. Introduction The globe has become polluted to such an extent that industrial contaminants can be found in the air, soil, water, food supply and is a cyclical problem in the trash and disposal industry.1-3 The processing and packaging of food itself and the agricultural contamination add these chemicals into the human dietary consumption chain.4, 5 Many contaminants can be inhaled or absorbed through the skin during bathing, showering, brushing the teeth, etc. Polyfluoroalkyl Substances (PFAS) represent 15,000 different variations of chemical compounds. The known health effects from PFAS exposure can be summarized as neurotoxic, carcinogenic, and fertility threat.6-8 Clinically, patients exhibit known laboratory results, signs and symptoms when exposed to PFAS including high cholesterol, low Vitamin D, thyroid disorders, Attention-Deficit Hyperactivity Disorder9-11. There are no studies on increasing its bioelimination, yet the media has dubbed these “forever chemicals” because the original PFOS (with 8 carbons) takes over 27 years to eliminate from the body. These chemicals are still being released into the water supply in thousands of communities according to the United States Environmental Working Group. Unfortunately, this Environmental Working Group Map is incomplete. It fails to list every environmental contamination site leaving citizens to have to test their own water and blood. One example of a PFAS contamination site is in Springfield, Missouri where there is PFAS in the water supply due to ongoing industrial contamination.12 The PFAS is spilling into the James River that flows Southwest from Springfield to Table Rock Lake in Branson, Missouri, which is a popular tourist destination. This water contamination is thought to be far-reaching, affecting Northwest Arkansas and is gaining the attention of tort attorneys. The PFAS level in Springfield, MO is above the limit placed by the Environmental Protection Agency at 4 parts per trillion and the Missouri Department of Natural Resources has organized a PFAS Workgroup to help the community address the contamination. In this environment, the same clinical trend in the scientific literature was visibly noticed by the staff at a busy psychiatric urgent care in Springfield, MO. Staff frequently spoke of how often otherwise healthy people had low Vitamin D, thyroid dysfunction, abnormal lipids, pain and symptoms of Attention Deficit Hyperactivity Disorder at all ages. In the majority of cases, these were the only medical problems these people had. The rates of abnormal labs and medications/supplements for Vitamin D, thyroid dysfunction and dyslipidemia in this vulnerable population are reported here. Methods Chart reviews were conducted for patients attending a psychiatric urgent care in Springfield, MO in July 2024. Inclusion criteria was having had a full panel of laboratory studies within the previous 18 months. Labs had to include a Vitamin D level, full lipid panel and full thyroid panel with at least TSH, T4 (conjucated/unconjucated), and T3 . Exclusion criteria were patients missing laboratory studies for either Vitamin D, lipid panel or thyroid panel. Age, gender, number of medical diagnoses, vitamin D supplement usage, TSH, T4 (or free T4), T3, total cholesterol, triglycerides, HDL, calculated VLDL, calculated HDL, and statin use were studied. Results Twenty-six patients were included in this study (n=26). Ages ranged from 8-68. Thirty-eight percent were male and 62% were female which is typical in outpatient psychiatric practice. Out of nine total lab tests, seven labs were above the expected 5% outliers of the reference range (Table 1). Over 73% of patients had elevated calculated LDL, 46.2% had abnormal total cholesterol, 38.5% had low Vitamin D, 30.8% had abnormal TSH values, 19.
