Tick-borne Co-infections: Presentation, Diagnosis and Treatment

May 26th-27th, 2014

The talk discussed the clinical presentation of Lyme Disease and associated co-infections, as well as the various diagnostic and therapeutic options available. Extensive scientific references on the diagnosis and treatment of different tick borne infections was discussed, including bacterial infections such as Lyme disease, Ehrlichia, Anaplasma, Bartonella, Mycoplasma, Chlamydia, Rocky Mountain Fever (RMSF), Typhus, Tularemia, Q-Fever, Brucellosis, Tick paralysis, and other new borrelia species, such as B. miyamotoi. There was discussion on tick-borne parasitic diseases such as Babesiosis and other piroplasms, and the expanding number of new viral infections being found in ticks, including the Heartland virus, Powassan encephalitis and other viral encephalopathies. Classical medical treatments was discussed for each infection, including side effects, drug interactions, and laboratory follow-up. This session also illustrated how different co-infections may contribute to chronic symptomatology in patients previously treated for Lyme disease.

Spécial investigation 2014 Lyme : l'épidémie invisible

October 27, 2014

There is a new french documentary on Lyme disease being released tonight on Canal plus in France. It was done by Bernard Nicolas and his son, where they filmed me both in Strasbourg, and in my medical office, where I discuss the issues with tick-borne diseases in Europe and the US. We are awaiting a translation with subtitles in English.

Your Environmental Minute On Location - Dr. Richard I. Horowitz
September 26, 2014

Dr Adrienne Sprouse just sent me this interview on Lyme disease that I did when I was a speaker at the American Academy of Environmental Medicine's 2013 annual scientific conference. The AAEM's 2014 conference is being held this year in Albuquerque, New Mexico, and the organization is an excellent resource for patients and health care providers who want the most up to date information on how environmental toxins affect our health. Many of my Lyme-MSIDS patients test positive for environmental chemicals like heavy metals and mold toxins, and these can adversely impact the course of treatment of some patients. Chapter 8 in my book discusses Lyme and environmental toxins in detail.

Bottom Line Publications: Lyme Disease & Other Tick-Borne Diseases Webcast
June 1, 2014

I did a one hour video interview on Lyme and associated tick-borne infections with Sarah Edelson-Hiner, the president of Bottom Line publications. It is now online and available for viewing. We had a lively conversation about the growing epidemic of tick-borne diseases, the inadequacy of testing, and how Lyme can imitate many different illnesses. I also discussed some of the most important points on the MSIDS map which help individuals regain their health. Please click on picture below to view free web cast.

Why Can't I Get Better? The Lyme MSDIS Map in Chronic Disease HD 1
May 17, 2014

At the May 17, 2014 "Symposium on Tick-borne Diseases", Dr. Richard Horowitz provided the attendees with a detailed list of contributing factors which can cause a delay in recovery from Lyme disease. The discussion follows his excellent book of the same title which is available from major booksellers. The discussion is not limited to only those patients with Lyme disease - it is relevant for any person suffering from a chronic illness. The discussion is approximately an hour and a half long. The "Symposium on Tick-borne Diseases" was hosted by the Lyme Disease Association of the Eastern Shore of Maryland, a 501(c)(3) non-profit organization which provides educational resources on tick-borne diseases.

Dr Horowitz raconte la maladie de Lyme (1)

May 20, 2014

From Editeur Thierry Soucar: Des millions de personnes sont infectées par la maladie de Lyme sans le savoir. Comment est-ce possible ? Dans cette vidéo, le Dr Richard Horowitz, spécialiste mondial de Lyme, auteur de Soigner Lyme et les maladies chroniques inexpliquées (Thierry Souccar Editions, juin 2014) explique comment cette maladie se transmet à l’homme et comment elle peut évoluer en prenant des formes complexes et sournoises, rendant son diagnostic et son traitement difficiles. Lyme peut en effet mimer de nombreuses maladies chroniques telles que la fibromyalgie, la polyarthrite ou la sclérose en plaques, c’est pourquoi le Dr Horowitz parle de « grand imitateur ».

We are in the middle of a worldwide epidemic of Lyme and associated tick-borne diseases. Chantal Perrin is a documentary filmmaker from France who traveled across the globe to track Lyme disease in the US, France, parts of Europe and Africa. In this revealing documentary being released today throughout Europe, she tells the story of how people across the world are getting sick, and how our health care systems continue to deny the existence of this growing medical threat, leading to widespread suffering and disability.

I have patients with Lyme and associated tick-borne disorders who come to see me from Canada, Belgium, France, Switzerland, Austria, Holland, England, Norway, Australia, New Zealand and Mexico, as they are unable to get effective care in their country. I am featured in this film and interviewed in both my medical practice in the United States, as well as in France where I am lecturing to doctors and patients on the diagnosis and treatment of Lyme and associated co-infections, discussing how to use the MSIDS model to treat chronic persistent disease. Dr Rick Ostfeld from the Cary Institute, and Dr Eva Sapi from the University of New Haven are also interviewed in this film, as are physicians and researchers from across the world.

This film highlights the politics of Lyme disease, the unreliability of testing, the rapidly spreading and multisystemic nature of tick-borne illness, and how worldwide research is being hampered by socio-political economic challenges. The film makes it clear that patients are suffering as the scientific community battles about the etiology and treatment of this disease, and that "we rapidly need to come to a clear scientific consensus, not a consensus of denial".

Please feel free to share this film with your family and friends. It is an important work with a story that desperately needs to be told.

Fox 45: Left Virtually Helpless as Disease Ravages ...

May 13, 2014

I was interviewed last night on Fox news in Baltimore about Lyme disease. A young man came to see me after seeing 16 other specialists for his neurological deterioration. I found heavy metals, mold toxins, as well as Lyme disease and associated co-infections (including West Nile exposure) contributing to his abnormal neurological function. This case highlights the need for health care providers to understand the diverse neurological manifestations of Lyme and associated tick-borne disorders, and to look for multiple overlapping etiologies on the Lyme-MSIDS map that can cause resistant neurological symptoms.
