Differential immune responses and microbiota profiles in children with autism spectrum disorders and co-morbid gastrointestinal symptoms
Published: 2018
SYNOPSIS

Autistic children with gastrointestinal symptoms have an imbalance in their immune response that affects behavior and quality of life.

Rose DR, Yang H, Serena G, Sturgeon C, Ma B, Careaga M, Hughes HK, Angkustsiri K, Rose M, Hertz-Picciotto I, Van de Water J, Hansen RL, Ravel J, Fasano A, Ashwood P. Brain, Behavior, and Immunity. 2018;70:354-368.

SUMMARY

Children with autism spectrum disorder (ASD) and concurrent gastrointestinal (GI) symptoms have a more imbalanced immune response, a more disturbed gut microbiome and worse behavioral outcomes (such as irritability, agitation, social withdrawal, lethargy, hyperactivity and noncompliance) than ASD children without GI symptoms. The study additionally looked at typically developing children with and without GI symptoms and found that ASD+GI children stood out compared to those two groups as well. Children with ASD plus GI symptoms may have a “propensity” toward leaky gut that contributes to their other symptoms and clinical outcomes.

Thimerosal changes protein conformation and increase the rate of fibrillation in physiological conditions: Spectroscopic studies using bovine serum albumin (BSA)
Published: 2018
SYNOPSIS

Thimerosal contributes to the formation of abnormal proteins associated with Alzheimer’s and other diseases.

CITATION

Santos JCN, da Silva IM, Braga TC, de Fátima Å, Figueiredo IM, Santos JCC. Thimerosal changes protein conformation and increase the rate of fibrillation in physiological conditions: Spectroscopic studies using bovine serum albumin (BSA). International Journal of Biological Macromolecules. 2018;113:1032-1040.

SUMMARY

A series of experiments suggests that the effects of the vaccine preservative thimerosal on the structure of important protein molecules in the blood are one likely cause of thimerosal’s toxicity, contributing to the development of neurodegenerative and other diseases. Using a cow protein as a proxy to assess thimerosal’s impact on human serum albumin (a protein made by the liver), the study found that thimerosal accelerates the build-up of abnormal protein deposits that are associated with at least 25 diseases, including Alzheimer’s, Parkinson’s and type 2 diabetes. When bound to albumin, thimerosal also may result in “more efficient distribution” of mercury in the body.

Rethinking mercury: the role of selenium in the pathophysiology of mercury toxicity
Published: 2017
SYNOPSIS

Mercury in the body produces a selenium deficiency state that increases toxicity.

CITATION

Spiller HA. Rethinking mercury: the role of selenium in the pathophysiology of mercury toxicity. Clinical Toxicology. 2018;56(5):313-326.

SUMMARY

This study makes the case that mercury’s multifaceted interactions with selenium are a central feature of mercury toxicity. The authors argue that “the previously suggested ‘protective effect’ of selenium against mercury toxicity may in fact be backwards”—because of mercury’s affinity for selenium, mercury can actually produce a selenium deficiency state that promotes oxidative stress and inhibits the body’s regenerative mechanisms. Depending on the form of mercury and other factors, selenium supplementation may have some benefits for restoring adequate selenium status and mitigating the toxicity of mercury, but it does not appear to promote increased elimination of mercury.

Aluminum and silica in drinking water and the risk of Alzheimer’s disease or cognitive decline: findings from 15-year follow-up of the PAQUID cohort
Published: 2008
SYNOPSIS

Higher aluminum intake from drinking water is associated with an increased risk of cognitive decline, dementia and Alzheimer’s disease.

CITATION

Rondeau V, Jacqmin-Gadda H, Commenges D, Helmer C, Dartigues JF. Aluminum and silica in drinking water and the risk of Alzheimer’s disease or cognitive decline: findings from 15-year follow-up of the PAQUID cohort. American Journal of Epidemiology. 2009;169(4):489-496.

SUMMARY

A long-term study in Southern France found that a higher intake of aluminum from drinking water was linked to an increased risk of cognitive decline, dementia and Alzheimer’s disease. Conversely, an increase in silica intake (10 mg/day) reduced the risk of dementia. A unique feature of the study, which followed elderly individuals for 15 years, was its measurement of individual daily intake of drinking water (both tap and bottled water), in addition to assessing the geographical concentrations of aluminum and silica.

Genetic Basis for Adverse Events Following Smallpox Vaccination
Published: 2008
SYNOPSIS

Three gene variations are associated with adverse reactions to smallpox vaccination.  

CITATION

Reif DM, McKinney BA, Motsinger AA, Chanock SJ, Edwards KM, Rock MT, Moore JH, Crowe Jr. JE. Genetic basis for adverse events following smallpox vaccination. The Journal of Infectious Diseases. 2008;198(1):16-22.

SUMMARY

A pair of NIH-funded studies identified three genetic variations that make people more susceptible to systemic adverse events following smallpox vaccination. By studying the smallpox vaccine, the researchers focused on a vaccine historically noted for frequently causing adverse reactions in population-wide vaccination programs. In the two studies, 16/96 and 24/46 individuals experienced systemic adverse events after vaccination, and three candidate genes (MTHFR, IRF1 and IL4) had the strongest association with the adverse events. In susceptible individuals, “vaccination appears to trigger an acute inflammatory response that is excessive.”

An investigation of infant deaths following initial hepatitis B vaccination based on the Vaccine Adverse Event Reporting System (VAERS), 1992-2002
Published: 2007
SYNOPSIS

Neonatal deaths following hepatitis B vaccination should be investigated as possible vaccine-related deaths.

CITATION

Soldatenkova VA, Yazbak FE. Medical Veritas. 2007;4:1414-1421.

SUMMARY

This study argues that all unexpected neonatal deaths occurring after initial hepatitis B vaccination should be systematically investigated. Over one-fifth (22%) of neonatal hepatitis B vaccine injuries reported to the U.S. Vaccine Adverse Event Reporting System (VAERS) from 1992 to 2002 were deaths (38/170) that, in nearly all cases, occurred within hours or days of vaccination. Although most of the deaths were officially classified as sudden infant death syndrome (SIDS) or “unexplained” rather than as vaccine-related deaths, the authors note “a statistically significant increase in [the] proportion of neonatal SIDS since implementation of universal vaccination of newborns against hepatitis B.” The VAERS reports also are suggestive of higher risks for premature, small, or slightly ill infants.

Public health and economic consequences of methyl mercury toxicity to the developing brain
Published: 2005
SYNOPSIS

In utero exposure to methylmercury from power plants and seafood is associated with lifelong loss of intelligence and billions of dollars in lost productivity.

CITATION

Trasande L, Landrigan PJ, Schechter C. Public health and economic consequences of methyl mercury toxicity to the developing brain. Environmental Health Perspectives. 2005;113(5):590-596.

SUMMARY

This study shows that the IQ losses associated with methylmercury toxicity cost the U.S. economy billions of dollars in lost productivity each year. Hundreds of thousands of American children in any given year have cord blood levels of methylmercury associated with lowered intelligence, traceable to in utero exposure to power plant emissions or to maternal seafood consumption. The loss of intelligence that results “causes diminished economic productivity that persists over the entire lifetime of these children”—amounting to about $8.7 billion annually.

Thimerosal induces toxic reaction in non-sensitized animals
Published: 1994
SYNOPSIS

Thimerosal used in vaccines increases risks of side effects.

CITATION

Uchida T, Naito S, Kato H, Hatano I, Harashima A, Terada Y, Ohkawa T, Chino F, Eto K. Thimerosal induces toxic reaction in non-sensitized animals. International Archives of Allergy and Immunology. 1994;104(3):296-301.

SUMMARY

A two-decades-old study in mice showed that thimerosal in vaccines may “augment” vaccine side effects in humans. Injection of a thimerosal-containing solution into mice resulted in hypersensitive reactions, including severe swelling and acute inflammation at the injection site with an hour of receiving the injection.
