Cut a hole in the immune system?

During the first half of the 20th century, every parent and child feared the word “polio”. In an epidemic, it attacked male and female, black and white, from rural communities to suburbia. Most people understood that a virus caused polio, but no one knew where the virus came from or how victims would fare. Often, the virus entered the body, created mild, flu-like symptoms, and left it virtually unscathed. Even though, in any community, most people would never get paralysed, pictures of iron lungs and braces would silently ask the question, “Will you be next?”  If, rather than immunity, a person got paralytic polio, the  outcome of conventional medical treatment might be some sort of deformity, or for the worst bulbar polio cases, weeks or a lifetime in an iron lung, or death.  Everyone knew certain aspects of the polio virus: It was highly contagious; struck without warning and preferred children and young adults; and the medical profession could offer neither prevention or cure. [1]

In 1954 a newspaper article quoted a study published in the prestigious Journal of the American Medical Association:

Analysis of the data suggested that the absence of tonsils and adenoids, regardless of the time of their removal in relation to the onset of poliomyelitis, increased the risk that the bulbar form of the disease would develop. [2] Read more

Polio: Causes and Effects, Part I

We saw in our first [1] blog on polio that infection with this virus was common, but paralytic polio was rare. In our second [2] article we reviewed the history of polio and the significant number of cases of paralysis from other causes which were blamed on polio. In the third [3] article we looked at one of the explanations for the rise of paralytic polio in advanced countries and the collapse of this explanation as polio increased in developing countries.

With polio, is there one cause, the virus, and one effect, paralysis? Obviously not, as the results of infection with the polio virus range from absolutely nothing to death. In this series we are going to review some of the factors which, combined with the presence of the virus, can move the situation from no symptoms and no problems, to paralysis.

A characteristic of infection with polio is the length of time it takes to clear the virus from the body and create immunity to polio.

…the interval between initiation of infection and appearance of CNS signs may be as long as several weeks, which accounts for the great variation in the incubation period of the disease. [4]

CNS means inflammation of the central nervous system. Someone can be carrying around a happily multiplying polio virus in the nose, throat and gut system, and other non-neural areas of the body, for a period of weeks without having any symptoms to indicate that the virus is there. “Non-symptomatic response” to polio virus exposure, results in eventual clearing of the virus from the system, permanent immunity to that strain of polio, and is the normal bodily response to the polio virus.

However, if something occurs during the several weeks of polio virus carriage which opens up access to the central nervous system to the virus, then the polio moves from asymptomatic to paralytic. There is a list of provokers which cause polio to invade the CNS.   Today we are going to consider one cause which we can credit to the medical profession. Read more

Polio and Sanitation

KHAGARIA: On the sandy banks of Kosi river in north Bihar, a quiet crowd of several hundred people is waiting in the sizzling morning sun. A speck appears in the pale blue summer sky, rapidly growing in size — its a gleaming white helicopter. Within seconds it is hovering above the opposite bank, amidst the cornfields.

The crowd is awestruck at the monstrous machine as it settles down in billowing clouds of sand. Out comes the man everybody has been waiting to see — Bill Gates.

Bill Gates has come to find out why polio eradication is failing in Bihar. He asks questions about immunization strategies and tries to figure out what sort of technical problems are blocking universal vaccine delivery.

People complain of lack of basic health facilities…There are only 49 auxilliary nurse and midwives under the PHC, against a sanctioned strength of 76…So, the delivery of basic health services is itself a distant dream…The villagers hope against hope. Isn’t the spread of polio linked to lack of sanitation and basic health facilities? Gates acknowledges this fact but says that it is for the government to do the needful. “We are concentrating on the eradication of polio, which is achievable through vaccines,” he says. [1]

Polio epidemics first appeared in the mid-nineteenth century. Many doctors and scientists struggled with the mystery: why, as living conditions improved, did incidents of paralysis increase? Out of all the changes that came with modernity, improved sanitation was chosen as the change which caused polio to turn from a mild illness to one that left death and permanent damage in its wake.  Here is an excellent example  from a 2007 medical article which summarizes the concept:

Prior to the 20th century, virtually all children were infected with PV while still protected by maternal antibodies. In the 1900s, following the industrial revolution of the late 18th and early 19th centuries, improved sanitation practices led to an increase in the age at which children first encountered the virus, such that at exposure children were no longer protected by maternal antibodies. Consequently, epidemics of poliomyelitis surfaced . [2] Read more

Polio and Acute Flaccid Paralysis

In post one of this series on polio, a term was introduced: “Acute Flaccid Paralysis”. [1]

Acute Flaccid Paralysis is a term which applies to the exact clinical symptoms you would expect to see from poliovirus infection, but which are not necessarily caused by polioviruses. Paralytic polio is actually considered a sub-category in the broad umbrella of acute flaccid paralysis. See pages 300-312 [1] for a chart and summary of many other causes of AFP, a few of which are: Guillaine-Barre syndrome, Cytomegalovirus polyradiculomyelopathy, Acute transverse myelitis, Lyme borreliosis, nonpolio enterovirus and Toxic myopathies.

For many years the medical profession assumed that when they saw paralysis with a particular cluster of symptoms, it was poliomyelitis. The 1954 Francis Trials of the Salk vaccine [2] triggered a reconsideration of this assumption, and a major change in the diagnostic criteria.

How were polio cases counted in 1954?

In 1954 most health departments worked with the WHO definition:

“…Signs and symptoms of nonparalytic poliomyelitis with the addition of partial or complete paralysis of one or more muscle groups, detected on two examinations at least 24 hours apart.” [3, p. 88]

How were polio cases counted in 1955?

In 1955 the criteria were changed to conform more closely to the definition used in the 1954 field trials: residual paralysis was determined 10 to 20 days after onset of illness and again 50 to 70 days after onset. [3, p. 88]

Thus, simply by changes in diagnostic criteria, the number of paralytic cases was predetermined to decrease in 1955-1957, whether or not any vaccine was used. At the same time, the number of nonparalytic cases was bound to increase because any case of poliomyelitis-like disease which could not be classified as paralytic poliomyelitis according to the new criteria was classified as nonparalytic poliomyelitis. Many of these cases, although reported as such, were not non-paralytic poliomyelitis. [3, p. 88] (emphasis added)

It was after the SALK vaccine was introduced, when fully vaccinated people continued to get “polio”, that doctors started looking a lot more carefully at the viruses in individuals. Many viruses were found to cause paralysis, for example coxsackie B, enterovirus 71, etc. Read more

Medical Double Standards in the Third World

    When it comes to third world medicine we almost invariably hear from the WHO about the successes of massive vaccination programs. If you look into the recent agenda for the World Health Assembly [1] you will find pandemic influenza vaccines at the top of the technical matters, and in the status section, the eradication of Poliomyelitis is at the top of that section. What is glaringly absent is a discussion of the pervasive double standards in research ethics, health-care safety and professional rigor that exist in the developing world. The WHO and its medical partners won’t talk about it publicly because when you look at the numbers, it is directly implicated in the suffering and ultimate death of millions of people in the developing world. That is what we’ll cover in this piece.

    It is well known that needle re-use can be a major cause of virus transmission. In 2000, a WHO press release states:

    Unsafe Injection practices have serious large-scale consequences…”unsafe injection practices throughout the world result in millions of infections which may lead to serious disease and death. Each year over-use of injections and re-use of dirty syringes and needles combine to cause an estimated 8 – 18 million hepatitis B virus infections, 2.3-4.7 million hepatitis C virus infections and 80,000 – 160,000 infections with HIV/AIDS worldwide. [2]

    That same press release uses an epidemic of Hepatitis C that occurred from Schistosomiasis treatment in Egypt. Notably absent is any discussion of the massive immunization campaigns waged throughout the third world coincident with the massive epidemics of HIV and other infectious diseases. However, someone there must be aware of the potential problem because the press release states the following at the end:

    In addition, to ensure the safety of immunization injections, WHO, the United Nations Children’s Fund (UNICEF), the United Nations Population Fund (UNFPA), and the International Federation of the Red Cross and Red Crescent Societies (IFRC) have recently called for the exclusive use of auto-disable (AD) syringes for immunization by the end of 2003.[2]

    We know quite reliably that the WHO knew years prior to this press release (2003) that medical practices in the developing world were problematic. As Gisselquist outlines in his 2009 article [3] the WHO was quietly giving UN employees the following advice in 1991.

    take special precautions to avoid HIV transmission via blood . . . If you are not carrying your own needles and syringes, avoid having injections unless they are absolutely necessary . . . Avoid tattooing and ear-piercing. Avoid any procedures that pierce the skin, such as acupuncture and dental work, unless they are genuinely necessary. Before submitting to any treatment that may give an entry point to HIV, ask whether the instruments to be used have been properly sterilized.[3]
