Fever Increases Immune System Defense, Study Shows

Fever Increases Immune System Defense, Study Shows

Fever Immune System
The Huffington Post   Posted: 11/3/11 06:05 PM ET
A new study adds more reason to why our bodies employ fevers as a defense against sickness.
Researchers from Roswell Park Cancer Institute found that a higher body temperature can help our immune systems to work better and harder against infected cells. The finding was published in the Journal of Leukocyte Biology.
"Having a fever might be uncomfortable, ... but this research report and several others are showing that having a fever is part of an effective immune response," John Wherry, Ph.D., deputy editor of the Journal of Leukocyte Biology, said in a statement.
Before, researchers thought that fevers worked by hindering dangerous microbes from multiplying, Wherry said.
But "this new work also suggests that the immune system might be temporarily enhanced functionally when our temperatures rise with fever," he said in the statement, though he noted that the finding should only prompt people to reconsider how they treat mild fevers, and not fevers that are dangerously high.
The secret is in a kind of immune cell, or lymphocyte, called a CD8+ cytotoxic T-cell. This kind of lymphocyte is able to destroy cells infected with viruses and even tumor cells, researchers said. Researchers found that a higher body temperature (like one achieved in a fever) raises the number of these CD8+ cytotoxic T-cells, which means a greater body response against infection.
To find this, researchers injected mice with an antigen and saw how the CD8+ cytotoxic T-cells activated to react to the antigen. Then, they raised the body temperatures of half the mice by 2 degrees centigrade, while leaving the temperatures of the other = mice alone. They found that the mice whose body temperatures were raised had more of the CD8+ cytotoxic T-cells than the mice without raised body temps.
The rise in mouse's body temperature is "similar to that that happens in fever," study researcher Elizabeth Repasky told the Toronto Star.
University of Pittsburgh Medical Center clinical associate professor Dr. Amesh A. Adalja, who wasn't involved with the study, told MSNBC that the finding shouldn't mean a fever should never be treated because too-high fevers can lead to brain cell damage. Parents should still take care to lower fevers in children, particularly if the fever is above 102 degrees Fahrenheit, since high fever can lead to seizures, Adalja told MSNBC.
MSNBC reports:
Adalja also warns it"s also not worth the risk to your own health if you have heart disease, have suffered a stroke or endure other medical complications. "This is not a blanket recommendation," he says. "Secondary consequences to the fever can cause other conditions in the patient to occur or worsen. If someone has a persistent fever of 104, it's a sign of infection, and it"s not just some viral thing you are going to get over."
This is certainly not the first research to suggest that fevers ramp up our body's immune responses. Discover magazine reported in 2007 on another Roswell Park Cancer Institute mouse study, which showed that mice that were heated up produced more immune cells to fight disease than mice that weren't heated.

Arthritis Prevention and Chiropractic

Arthritis Prevention and Chiropractic
Chiropractic prevents arthritis in accident victims, the elderly and the sedentary
By Mark Studin DC, FASBE(C), DAAPM, DAAMLP
 
According to the Arthritis Foundation (2007), "Forty-six million [46,000,000] Americans are currently living with arthritis, the nation's leading cause of disability, and we are all paying a high price for it. The Centers for Disease Control and Prevention (CDC) announced that the annual cost of arthritis to the United States economy was $128 billion in 2003 and increased by $20 billion between 1997 and 2003.

CDC attributes the dramatic increase to the aging of the population, predominantly baby boomers, and increased prevalence of arthritis. CDC also estimates an additional 8 million new cases of arthritis will be diagnosed in the next decade" (
http://www.arthritis.org/cost-arthritis.php
).

Arthritis, A.D.A.M., Inc. (2010, February 5), "...is inflammation of one or more joints, which results in pain, swelling, stiffness, and limited movement. There are over 100 different types of arthritis...
Causes, incidence, and risk factors
Arthritis involves the breakdown of cartilage. Cartilage normally protects the joint, allowing for smooth movement. Cartilage also absorbs shock when pressure is placed on the joint, like when you walk. Without the usual amount of cartilage, the bones rub together, causing pain, swelling (inflammation), and stiffness.
You may have joint inflammation for a variety of reasons, including:

- An autoimmune disease (the body attacks itself because the body immune system believes a body part is foreign)
- Broken bone
- General wear and tear
- Infection (usually cause by bacteria or viruses)... 

With some injuries and diseases, the inflammation does not go away or destruction results in long-term pain and deformity. When this happens, you have chronic arthritis. Osteoarthritis is the most common type and is more likely to occur as you age. You may feel it in any of your joints, but most commonly in your hips, knees or fingers. Risk factors for osteoarthritis include:

- Being overweight
- Previously injuring the affected joint
- Using the affected joint in a repetitive action that puts stress on the joint (baseball players, ballet dancers and construction workers are all at risk)

Arthritis can occur in men and women of all ages. About 37 million people in America have arthritis of some kind, which is almost 1 out of every 7 people" (http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0002223). With hypomobility (less mobility or movement), adhesions occur in a joint (the region where 2 bones connect).
According to A.D.A.M., Inc. (2010, March 30), "Adhesions are bands of scar-like tissue that form between two surfaces inside the body and cause them to stick together. As the body moves, tissues or organs inside are normally able to shift around each other. This is because these tissues have slippery surfaces.
Causes, incidence, and risk factors
Inflammation (swelling), surgery, or injury can cause adhesions to form almost anywhere in the body...Once they form, adhesions can become larger or tighter over time. Symptoms or other problems may occur if the adhesions cause an organ or body part to twist, pull out of position, or be unable to move as well.
Adhesions may form around joints such as the shoulder...or ankles, or in ligaments and tendons. This problem may happen:

- After surgery or trauma
- With certain types of arthritis
- With overuse of a joint or tendon

Symptoms
Adhesions in joints, tendons, or ligaments make it harder to move the joint and may cause pain...Adhesions in the pelvis may cause chronic or long-term pelvic pain.
Signs and tests
Most of the time, the adhesions cannot be seen using x-rays or imaging tests" (http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0002462).
Over time, with a sedentary lifestyle as seen in many portions of the population and increasingly with the elderly, joints become hypomobile. Hypomobility is also seen in trauma-related cases and repetitive use injuries, such as reading while looking down for extended periods, carrying heavy items, holding the phone between one's shoulder and ear, prolonged use of hands, wrists, back and neck, excessive use of computers, etc. As time progresses, internal scar tissue or adhesions continue to develop and further increases the loss of mobility.
Cramer, Henderson, Little, Daley and Grieve (2010), cite previous studies that have shown that adhesions have been found in numerous hypomobile (loss of normal movement) joints and that spinal adjusting separates the articular surfaces of the joint. The researchers inquired as to whether connective tissue adhesion developed in lumbar articular joints as a consequence to intervertebral hypomobility and utilized animal studies.  They concluded that "...hypomobility results in time-dependent [adhesions]..." (Cramer et al., 2010, p. 508). In other words, internal scar tissue (arthritis) developed within the joints over time.

Cramer et al. (2010) sited previous studies that found the spinal adjustment separates the joints which could break up intra-articular adhesions. In other words, in their animal studies, spinal adjustments/manipulation increased the "Z gap" or spacing between the joints/bones and the mobility of the joints. If this applied in humans, the adjustments would then prevent further development of adhesions and degeneration and osteophytes, which is how the arthritic process progresses.

While arthritis affects approximately 1 in 7 Americans, the prevention of and/or correction of arthritis would relieve a great strain on our economy. While not all arthritis is a result of hypomobility, much of it is. If every person was under chiropractic care, we could not only positively affect the lives of every American, we could potentially rescue the economy of the United States and every other country and insurer in the world that assumes risk for an aging and hypomobile society.

Scoliosis and Chiropractic Care



The average reduction of thoraco-lumbar scoliosis was 17.2° and was maintained for 24 months.
Function improved 70% and pain was reduced by 60%.

BY Mark Studin DC, FASBE(C), DAAPM, DAAMLP
According to the Mayo Clinic (2009), " Scoliosis is a sideways curvature of the spine that occurs most often during the growth spurt just before puberty. While scoliosis can be caused by conditions such as cerebral palsy and muscular dystrophy, the cause of most scoliosis is unknown. Most cases of scoliosis are mild, but severe scoliosis can be disabling. An especially severe spinal curve can reduce the amount of space within the chest, making it difficult for the lungs to function properly. Children who have mild scoliosis are monitored closely, usually with X-rays, to see if the curve is getting worse. In many cases, no treatment is necessary. Some children will need to wear a brace to stop the curve from worsening. Others may need surgery to straighten severe cases of scoliosis" (http://www.mayoclinic.com/health/scoliosis/DS00194). They go on to say that signs and symptoms of scoliosis may include, uneven shoulders, "Signs and symptoms of scoliosis may include: uneven shoulders, one shoulder blade that appears more prominent than the other, uneven waist, [and] one hip higher than the other" (Mayo Clinic Staff, 2009, http://www.mayoclinic.com/health/scoliosis/ DS00194/ DSECTION=symptoms).

"If a scoliosis curve gets worse, the spine will also rotate or twist, in addition to curving side to side. This causes the ribs on one side of the body to stick out farther than on the other side. Severe scoliosis can cause back pain and difficulty breathing. Go to your doctor if you notice signs or symptoms of scoliosis in your child. Mild curves can develop without the parent or child knowing it because they appear gradually and usually don't cause pain" (Mayo Clinic Staff, 2009, http://www.mayoclinic.com/health/ scoliosis/DS00194/ DSECTION=symptoms).

According to Lou et al. in 2010, three-dimensional lateral curvatures of the spine affect 2-3% of the adolescent population. According to ACT Youth who utilizes the 2000 US Census Bureau statistics, the number of adolescents in the United States is 41,747, 962. Averaging 2.5% of all adolescents having scoliosis equates to 1,043, 699 children facing issues as result of scoliosis. Lou et al. (2010) continue, "Brace (orthotic) treatment is recommended for growing children with curves of 25–45° Cobb angle. Surgery is the final treatment option for curves greater than 45° and its goals are to obtain safe correction, to produce a solid spinal fusion of the curve region, and to bring the spine and body into a more balanced position (p. 292). However, they conclude, " Although brace treatment for scoliosis has been used for more than fifty years, its effectiveness is still debatable... Most studies used the amount of curve progression (as measured by the Cobb angle) to determine the effectiveness of brace treatment. Some defined success as 5° or less curve progression" (Lou et al., 2010, p. 292).

While allopathic medicine is still entrenched in the debatable practice of bracing and eventually surgery with the eventual progression of scoliosis, there are proven solutions. Morningstar concluded in 2011 that as a result of chiropractic spinal adjusting and chiropractic spinal manipulation, a thoracolumbar curvature (scoliosis) averaged a 17.2° reduction that was maintained for 24 months, the length of the study. Across all spinal groups, an average of 10° reduction was realized that persisted for 24 months, again the length of the study. Morningstar also concluded that pain scales reduced by 60% at 24 months and function improved by 70% while respiratory capacity increased 7%. Although this was a limited study with 28 patients, it is the first scientific conclusion that documents and reflects the results of what chiropractors have been realizing in their offices for over a 100 years.

The real issue is that if adolescents have their curvatures reduced by 10°-17.2°, then bracing and surgery are not an option because they will not be indicated. As bracing has been deemed "highly questionable" in the literature and now the literature reflects chiropractic as a highly effective modality, the standard of care across professions should be chiropractic care for scoliosis as first line treatment and should be standardized in every discipline.
