Excercise and Crohns Disease

02.14.10

Canadian researchers found that for people with mild Crohns disease, taking a walk a few times per week helped boost their well-being and quality of life.Crohns disease is a chronic disorder that causes inflammation throughout the digestive tract.

Symptoms, which include diarrhea, abdominal pain and rectal bleeding, tend to flare-up periodically, and then go into periods of remission.There has been some concern that exercise could exacerbate these problems because of its potential effects on functioning in the digestive tract. However, studies have not shown this to be true.For the new study, Victor Ng and colleagues at the University of Western Ontario recruited 32 adults with Crohns disease.

All were either in remission or were suffering only mild symptoms.For three months, half of the study participants walked for 30 minutes, three days per week. The rest maintained their usual lifestyle. At the beginning and end of the study, all patients completed questionnaires on their symptoms, overall well-being and quality of life.At the end of the trial, the researchers found, the exercise group reported improved symptoms and gave higher ratings to their quality of life. In contrast, symptoms worsened in the comparison group.

The findings are published in the Clinical Journal of Sports Medicine.

“Exercise benefits almost everyone and chronic disease patients are no exception,” study co-author Dr. Wanda Millard told Reuters Health.

Though some doctors have been hesitant to recommend exercise for Crohns disease, light exercise like moderate walking is unlikely to have significant effects on patients’ intestinal function, Millard noted.She pointed out that there are several professional athletes with Crohns disease.

That being said, however, Millard cautioned that this and other studies of exercise and Crohns disease have included only patients in remission or with mild symptoms.

“Patients with moderate or severe symptoms of their Crohns disease should not engage in an exercise program until their symptoms are better controlled,” she advised. Most people are successful with the basic formula of dieting and exercise. A smaller number need the addition of medication. A small percentage fail in all of those methods. So the big question is what should those who are overweight do to get back to an acceptable weight?
Unfortunately, there is no easy answer.

Those who have failed exercise, dieting and weight loss medication have a big problem to overcome. They most likely have problems exercising because of their weight or other health problems. It can likely help manage it, if for nothing else it can reduce stress.Depression is often an issue because of failing weight loss programs. Medications either have too many side effects or just are not working.

Crohns Disease Surgery

01.17.10

Crohns disease can cause a variety of symptoms of gastrointestinal distress.

The three classic (though not specific) symptoms of inflammatory bowel disease are:
•    Persistent or recurrent diarrhea (possibly with blood, mucus, or pus)
•    Abdominal pain
•    Fever

There also may be signs and symptoms unrelated to the gastrointestinal tract. A doctor will obtain a complete medical history and perform a thorough physical examination, along with laboratory and diagnostic tests, to diagnose Crohns disease. The examination and other tests are necessary to rule out a number of transient conditions, such as viral, bacterial, or parasitic infection, that cause symptoms similar to Crohns disease.

Diarrhea
In cases of Crohns disease, patients often experience frequent loose or watery bowel movements. The stool is occasionally accompanied by thick, dark blood (not bright red smears of blood, which usually result from a bleeding hemorrhoid). There is less mucus or pus in the stool than in cases of ulcerative colitis.

Pain
Patients may experience crampy, achy, or even sharp pain in the affected area. Most often, patients with Crohns disease feel pain on the lower right side of the abdomen (lower right quadrant) and just below the bellybutton. This is because the majority of cases of Crohns disease involve disease in the terminal ileum, where the small intestine meets the large intestine. The terminal ileum crosses from left to right just above the beltline, and joins the large intestine in the lower right quadrant. The type of pain associated with Crohns disease depends on what part of the GI tract is affected. Disease in the terminal ileum generally causes sharp pain, while disease in the colon causes more crampy pain, similar to that that of ulcerative colitis. Pain is sometimes relieved (temporarily) after a bowel movement.

Fever
Crohn’s is an inflammatory disease, and one of the key characteristics of the inflammatory process is fever. (The others are pain, swelling, and redness.) Some individuals with Crohns disease suffer a high fever, especially during the acute phase of a flare-up. Others run a persistent, low-grade fever. Fever may be accompanied by irritability and fatigue. Sometimes, the fever recurs each day, especially late in the day, then repeatedly breaks during sleep, causing night sweats.

Signs and Symptoms Unrelated To The GI Tract
A number of signs and symptoms that do not involve the gastrointestinal tract can occur with Crohns disease. These may occur at the same time as the intestinal symptoms, or may be experienced weeks or even months before any intestinal symptoms are noticed. If your doctor suspects inflammatory bowel disease, he or she will ask you detailed questions about whether or not these extra-intestinal symptoms have appeared:
•    Reddening and inflammation of the eye (iritis)
•    Joint pain (usually in the large joints of the knees, ankles, elbows, wrists, and shoulders), which sometimes migrates from one joint to another (migrating arthralgia)
•    Skin lesions, including tender red nodules on the shins or calves (erythema nodosum)
•    Sores inside the mouth (aphthous ulcers)

Crohns Disease Probiotics

11.30.09

Probiotics in the Treatment of Crohn’s Disease
Alterations in the bacterial milieu of the gut are common in Crohns disease. The use of various probiotic bacteria to promote a balance of appropriate intestinal flora has yielded mixed results. Mechanisms associated with the beneficial effects of probiotic therapy in Crohn’s Disease include:

(1) inhibition of pathogenic bacteria via growth suppression or epithelial binding
(2)  improved epithelial and mucosal barrier function; and
(3) altered immuno-regulation via stimulation of secretory IgA or reduction in TNF-alpha.

Saccharomyces boulardii
Plein et al demonstrated the efficacy of Saccharomyces boulardii (Sb) in a randomized, double-blind, placebo-controlled study of 20 Crohn’s Disease patients. Patients were given 250 mg Sb three times daily for 10 weeks and evaluated via bowel movement frequency and the CDAI index. Patients receiving Sb experienced a significant reduction in frequency of bowel movements (from 5.0 to 3.3 per day) and CDAI index (193 to 107) by week 10 of treatment.

Another study utilizing Saccharomyces boulardii therapy in 32 Crohn’s Disease patients demonstrated a significant benefit of a combination of Saccharomyces boulardii and mesalamine compared to mesalamine alone. Relapse in the mesalamine-only group was 37.5 percent at six months compared to only 6.25 percent in the mesalamine-plus Saccharomyces boulardii group.

E. coli (Nissle strain)
Pathogenic E. coli that adhere to and invade intestinal epithelial cells (IEC) have been isolated from ileal lesions of Crohns patients. Boudeau et al demonstrated the in vitro ability of a non-pathogenic E. coli strain (Nissle 1917) to prevent pathogenic E. coli strains from adhering to and invading IEC. When IEC were co-infected with probiotic Nissle strain and pathogenic E. coli, the Nissle strain exhibited a dose- and time-dependent adhesion to IEC, which prevented adhesion of various pathogenic E. coli strains by 78.0- 99.9 percent.

When IEC were pre-incubated with Nissle strain E. coli and pathogenic strains were added later, adhesion and invasion of pathogenic strains was inhibited by 97.2-99.9 percent. Malchow et al conducted a double-blind, randomized, placebo-controlled trial investigating the efficacy of E. coli Nissle strain 1917 for inducing and maintaining remission in 28 patients with colonic Crohns disease.

Patients were randomized to either 60 mg prednisolone daily (with a standard tapering schedule) plus twice daily doses of 2.5 x1010 probiotic Nissle strain E. coli (treatment group) or identical prednisolone therapy plus placebo (placebo group). The rate at which remission was achieved was comparable in both groups (85.7% for treatment patients versus 91.7% for placebo patients), but only 33.3 percent of patients in the E. coli treatment group relapsed at one year, compared to 63.6 percent in the placebo group.

Lactobacillus GG
Malin et al investigated the effect of oral Lactobacillus GG on the intestinal immunological barrier in a small study of 14 children with CD and seven control patients (hospitalized for investigation of abdominal pain but with no evidence of intestinal disease). Lactobacillus GG was administered to patients and controls at 1010 colony forming units mixed in liquid twice daily. Lactobacillus GG therapy significantly increased the IgA immune response in Crohns patients compared to controls, resulting in an improved mucosal barrier.

Another study of Lactobacillus GG demonstrated that administration in children with mildto- moderate stable Crohn’s Disease improved gut barrier function and clinical status after six months of therapy.228 However, a randomized, double-blind, placebo-controlled trial of 45 post-surgery Crohns patients given Lactobacillus GG for one year did not show it to be more effective than placebo in preventing disease recurrence.229

Can Viagra Help Crohns Disease

05.14.09

While well known for its effect on blood flow, until now Viagra has not been used to boost circulation in the intestine. That could change with the finding that Viagra can help treat Crohns disease. People with the long-term, inflammatory condition develop holes and ulcers in the intestine.

A team from University College London wondered whether an overactive immune reaction was the problem.The team carried out biopsies on six Crohns disease patients and nine healthy volunteers. The operation triggered an acute immune response in the healthy people, producing white blood cells to heal damage caused by the removal of cells. But the Crohn’s patients responded by producing far lower amounts of white blood cells. The researchers used Viagra to boost blood flow to the intestine in the patients with Crohns disease, thus increasing the flow of white cells to the damaged area.

Researchers in the U.K. have a new theory to explain the cause of Crohns disease, and they say medications like the erectile dysfunction drug Viagra may prove useful for treating the bowel disorder if they are right.In Crohns disease, chronic inflammation causes ulcers within the digestive tract that can lead to severe gastrointestinal symptoms, including abdominal pain, persistent diarrhea, and rectal bleeding.The most widely accepted theory is that an overactive immune system causes the damaging inflammation.

But researchers from the University College London say the opposite appears to be true.They believe a weaker-than-normal immune response triggers the bowel inflammation that leads to Crohns disease. The researchers tested this theory by treating 10 Crohn’s patients with 50 milligrams of Viagra after injecting them with the killed gut bacteria. They found that blood flow to the infected area improved.

“Increasing blood flow is an important part of the inflammatory response, and that is why this drug may work,” Segal says. “But we don’t yet know if this will give rise to successful treatment. We need to study this further to find out.” The disease usually affects the small intestine and one in every thousand people in the UK is afflicted with this miserable complaint.

But now scientists believe they have found the cause of Crohns disease, and they think it could be treated with Viagra.The team of researchers from University College London say they believe the cause is the opposite of what has been supposed and is triggered by a weak immune system, rather than an overactive one where cells are attacked by the body’s own immune system.

Crohn’s was previously thought to be an auto-immune disease and was treated with immuno-suppressant drugs. But the researchers led by Anthony Segal and colleagues have discovered that people with Crohn’s have a weak and unresponsive immune system which does not repair damage easily. They say the flow of blood to damaged cells is substantially reduced, and a drug such as Viagra, best known for its effects on erectile dysfunction, could help the healing process as it stimulates blood flow.

Since it was identified in the 1920s there have been many theories as to the cause of Crohn’s and it was often compared with tuberculosis, but attempts to find an infectious agent have failed.
The research team compared the immune system response of Crohn’s patients and healthy individuals to minor injuries, such as skin abrasions and discovered a difference in the number of white blood cells called neutrophils produced by the body to heal the damage in the bowel and on the surface of the skin.
