Arthur Krigsman is a pediatrician and gastroenterologist best known for his controversial research in which he attempted to prove that the MMR vaccine caused diseases, especially autism. He specializes in the evaluation and treatment of gastrointestinal pathology in children with autism spectrum disorders, and has written in support of the diagnosis he calls autistic enterocolitis. The original study that tied the MMR vaccine to autism and GI complaints conducted by one of Krigsman's associates has been found to be fraudulent, and the diagnosis of "autistic enterocolitis" has not been accepted by the medical community.
A graduate of Johns Hopkins University, Krigsman earned his Doctor of Medicine at the State University of New York Downstate College of Medicine at Brooklyn in 1989 and later completed his pediatric residency at SUNY Brooklyn's Kings County Medical Center. After completing pediatric gastroenterology fellowship in 1995, he joined the Department of Pediatric Gastroenterology of Beth Israel Medical Center in New York as Director through 2000, and later joined Lenox Hill Hospital from 2000 through 2004 in the same position. He subsequently left to work as director of the gastroenterology clinic at Thoughtful House, where he was colleagues with Andrew Wakefield. Krigsman holds board certification in general pediatrics and in pediatric gastroenterology, though no longer practices general pediatrics. [1] In April 2010, Krigsman left Thoughtful House to open a private practice in Austin and New York. [2]
In 2004, Krigsman left Lenox Hill under "questionable circumstances," after his hospital privileges were restricted from conducting endoscopies due to allegations that he was performing medically unwarranted endoscopies on autistic children for research purposes. [3] The Department of Health and Human Services Office for Human Research Protections later reviewed the situation, noting reports from the hospital that Krigsman applied for permission to conduct research but was not approved by the institution's Institutional Review Board, which was concerned about risk to patients from unwarranted procedures. The report also noted Krigsman nevertheless testified before a Congressional hearing about research he had done on 43 patients, and later refused to provide medical charts as requested by a committee set up by the hospital to investigate the situation, before resigning from the hospital in 2004. [4]
In 2005, Krigsman was fined by the Texas State Board of Medical Examiners for multiple violations, including representing he was available to see patients prior to obtaining his medical license in Texas, for failing to report previous regulatory sanctions by the Florida medical board, and for the disciplinary action by the Lenox Hill Hospital. [3]
The term "autistic enterocolitis" was coined by Andrew Wakefield in 1998 after the publication of his now-retracted study in The Lancet , where he purported an association between autistic regression, intestinal inflammation and the MMR vaccine. [5] In 2003, Krigsman, who was at Lenox Hill, reported similar findings as those of Wakefield, saying he found the intestines of 40 autistic children showed signs of inflammation, thus lending support to Wakefield's ideas that MMR was related to autism and also to gastrointestinal disease. [6] This information was not formally published until seven years later in 2010, in the non-MEDLINE indexed journal Autism Insights . [7] In April 2016, Da Capo Lifelong published the memoir of a mother with two autistic children, which heavily featured Dr. Krigsman and detailed his treatment protocol from the patient perspective. [8]
However, the concept of "autistic enterocolitis" has not been accepted in the medical community due to lack of rigorous studies confirming the condition, as many studies purportedly showing this diagnosis have been marred by numerous methodological faults. [9] Even a position statement by a panel of physicians sponsored by Autism Speaks that included Krigsman [10] concluded that the clinical significance of the findings of inflammation in the intestines is unknown as it is also found in children without autism. [11]
Andrew Wakefield, who later joined and worked with Krigsman at Thoughtful House, was found to have falsified the 1998 Lancet study, which was described as "an elaborate fraud." [12] [13]
Krigsman has testified as an expert witness in a number of test claims to the Office of Special Masters of the U.S. Court of Federal Claims (commonly known as the "Vaccine Court") by parents seeking compensation for damages purportedly caused by vaccination. The "Special Masters" rendering decisions about these cases have questioned his credibility due to previous regulatory sanctions by the Texas Medical Board and Lenox Hill Hospital, as well as concerns regarding the curriculum vitae provided by Krigsman. They noted concerns regarding a title he said he held at New York University Medical School which may not have matched his duties as well as possible misrepresentations of publications he has published. [1] [3] In one case, the judge noted that he thinks Krigsman was not a "credible witness" and that the parents who brought the case were "misled by physicians who are guilty, in my view, of gross medical misjudgment." [3] In another case, the judge noted of Krigsman's qualification for identifying a new disease like "autistic enterocolitis" which is "unrecognized by other authorities in the field, were, even when inflated, sadly lacking" and that his testimony about the existence of "autistic enterocolitis" was "speculative and unsupported by the weight of the evidence." [1]
The MMR vaccine is a vaccine against measles, mumps, and rubella, abbreviated as MMR. The first dose is generally given to children around 9 months to 15 months of age, with a second dose at 15 months to 6 years of age, with at least four weeks between the doses. After two doses, 97% of people are protected against measles, 88% against mumps, and at least 97% against rubella. The vaccine is also recommended for those who do not have evidence of immunity, those with well-controlled HIV/AIDS, and within 72 hours of exposure to measles among those who are incompletely immunized. It is given by injection.
Brian Laurence Deer is a British investigative journalist, best known for inquiries into the drug industry, medicine and social issues for The Sunday Times. Deer's investigative nonfiction book The Doctor Who Fooled the World, an exposé on disgraced former doctor Andrew Wakefield and the 1998 Lancet MMR autism fraud, was published in September 2020 by Johns Hopkins University Press.
Generation Rescue is a nonprofit organization that advocates the scientifically disproven view that autism and related disorders are primarily caused by environmental factors, particularly vaccines. The organization was established in 2005 by Lisa and J.B. Handley. Today, Generation Rescue is known as a platform for Jenny McCarthy's autism related anti-vaccine advocacy.
Many causes of autism, including environmental and genetic factors, have been recognized or proposed, but understanding of the theory of causation of autism is incomplete. Attempts have been made to incorporate the known genetic and environmental causes into a comprehensive causative framework. ASD is a neurodevelopmental disorder marked by impairments in communicative ability and social interaction, as well as restricted and repetitive behaviors, interests, or activities not suitable for the individual's developmental stage. The severity of symptoms and functional impairment vary between individuals.
Claims of a link between the MMR vaccine and autism have been extensively investigated and found to be false. The link was first suggested in the early 1990s and came to public notice largely as a result of the 1998 Lancet MMR autism fraud, characterised as "perhaps the most damaging medical hoax of the last 100 years". The fraudulent research paper, authored by discredited former doctor Andrew Wakefield and published in The Lancet, falsely claimed the vaccine was linked to colitis and autism spectrum disorders. The paper was retracted in 2010 but is still cited by anti-vaccine activists.
Andrew Jeremy Wakefield is a British fraudster, discredited academic, anti-vaccine activist, and former physician.
Classic autism, also known as childhood autism, autistic disorder, (early) infantile autism, infantile psychosis, Kanner's autism, Kanner's syndrome, or (formerly) just autism, is a neurodevelopmental condition first described by Leo Kanner in 1943. It is characterized by atypical and impaired development in social interaction and communication as well as restricted, repetitive behaviors, activities, and interests. These symptoms first appear in early childhood and persist throughout life.
The Autism Science Foundation (ASF) is a non-profit organization that funds evidence-based autism research and supports autism families. The organization was founded in April 2009 by Alison Tepper Singer, a former senior executive of Autism Speaks and the longest-serving public member of the Interagency Autism Coordinating Committee (IACC), and Karen Margulis London, co-founder of the National Alliance for Autism Research. Both Singer and London are parents of autistic children.
Autism spectrum disorders (ASDs) or autism spectrum conditions (ASCs) describe a range of conditions classified as neurodevelopmental disorders in the DSM-5, used by the American Psychiatric Association. As with many neurodivergent people and conditions, the popular image of autistic people and autism itself is often based on inaccurate media representations. Additionally, media about autism may promote pseudoscience such as vaccine denial or facilitated communication.
Michelle Cedillo v. Secretary of Health and Human Services, also known as Cedillo, was a court case involving the family of Michelle Cedillo, an autistic girl whose parents sued the United States government because they believed that her autism was caused by her receipt of both the measles-mumps-and-rubella vaccine and thimerosal-containing vaccines. The case was a part of the Omnibus Autism Proceeding, where petitioners were required to present three test cases for each proposed mechanism by which vaccines had, according to them, caused their children's autism; Cedillo was the first such case for the MMR-and-thimerosal hypothesis.
Vijendra Kumar Singh is a neuroimmunologist who formerly held a post at Utah State University, prior to which he was a professor at the University of Michigan. While affiliated with both institutions, he conducted some controversial autism-related research focusing on the potential role of immune system disorders in the etiology of autism. For example, he has testified before a US congressional committee that, in his view, "three quarters of autistic children suffer from an autoimmune disease."
Herman Hugh Fudenberg was an American clinical immunologist and the sole identified member of the Neuro Immuno Therapeutics Research Foundation (NITRF).
Paul Ashwood is an associate professor of immunology at the MIND Institute at the University of California Davis. His lab conducts research regarding the potential role of immune system disorders in autism, as well as other neurodevelopmental disorders such as Fragile X syndrome, Tourette syndrome, schizophrenia and mood disorders.
Timothy M. Buie is a pediatric gastroenterologist at Boston Children’s Hospital. Buie joined Harvard Medical School in 1998 after previously practicing at Pediatric Gastroenterology Associates for eight years. He was also the director of Gastrointestinal and Nutritional Services at MGH's Lurie Center for Autism. He is well known for his research pertaining to the possible connection between autism and gastrointestinal disorders, and has told the Interagency Autism Coordinating Committee that over half of autistic children experience gastrointestinal symptoms, whereas he stated that this was the case for "between 50 and 70%" of children with autism in an interview with ABC News. He has also said that a subset of autistic children may benefit from gluten-free, casein-free diets, and that more research is needed into this area. Buie was honored as "Professional of the Year" by the Autism Society of America in 2009.
Karoly Horvath is a Hungarian-American pediatrician and gastroenterologist who was formerly the director of the Pediatric Gastroenterology and Nutrition Laboratory at the University of Maryland School of Medicine. He is best known for proposing a link between secretin, gastrointestinal disorders and autism and for, as a result, proposing that secretin might be an effective treatment for autism.
John Walker-Smith is an Australian gastroenterologist well known for his work in pediatrics. From 1985 until his retirement in 2001, he was professor of pediatric gastroenterology at the University of London. He also formerly served as the editor-in-chief of the Journal of Pediatric Gastroenterology and Nutrition.
Vaxxed: From Cover-Up to Catastrophe is a 2016 American pseudoscience propaganda film alleging a cover-up by the Centers for Disease Control and Prevention (CDC) of a purported link between the MMR vaccine and autism. According to Variety, the film "purports to investigate the claims of a senior scientist at the U.S. Centers for Disease Control and Prevention who revealed that the CDC had allegedly manipulated and destroyed data on an important study about autism and the MMR vaccine"; critics derided Vaxxed as an anti-vaccine propaganda film.
The Lancet MMR autism fraud centered on the publication in February 1998 of a fraudulent research paper titled "Ileal-lymphoid-nodular hyperplasia, non-specific colitis, and pervasive developmental disorder in children" in The Lancet. The paper, authored by now discredited and deregistered Andrew Wakefield, and twelve coauthors, falsely claimed causative links between the measles, mumps, and rubella (MMR) vaccine and colitis and between colitis and autism. The fraud involved data selection, data manipulation, and two undisclosed conflicts of interest. It was exposed in a lengthy Sunday Times investigation by reporter Brian Deer, resulting in the paper's retraction in February 2010 and Wakefield being struck off the UK medical register three months later. Wakefield reportedly stood to earn up to US$43 million per year selling diagnostic kits for a non-existent syndrome he claimed to have discovered. He also held a patent to a rival vaccine at the time, and he had been employed by a lawyer representing parents in lawsuits against vaccine producers.
Extensive investigation into vaccines and autism has shown that there is no relationship between the two, causal or otherwise, and that vaccine ingredients do not cause autism. Vaccinologist Peter Hotez researched the growth of the false claim and concluded that its spread originated with Andrew Wakefield's fraudulent 1998 paper, with no prior paper supporting a link.
