Brief Summary

Inflammatory Bowel Disease (IBD) is a group of inflammatory conditions of the small bowel and colon. Main types include Ulcerative Colitis and Crohn's Disease. Symptoms are often difficult to distinguish except for location and nature of changes. IBD complex arises with interaction of environmental, genetic factors, immunological responses, and chronic and recurring inflammation.

Many factor appear as contributory, but no single set of issues appear to explain the process. Microbiota, intestinal wall granulation or breach, dietary, genetic predisposition all appear to factors. Treatment is often reactive or suppressive medications, neither of which appears to reverse the disease processes. This study explores the value of a complex group of adipose-derived stem/stromal cells (AD-cSVF) in the disease process.

Detailed Description

IBD often presents clinically as abdominal pain, diarrhea (with and without blood), fever, weight loss, failure to thrive, and many related symptoms. Complications of the disorders may also include anemia, skin rashes, arthritis, severe chronic fatigue, and eye inflammatory changes.

It is felt that IBD disorders may be caused by combination of environmental, immune, genetic, and bacterial factors. Results of these issues produce a chronic inflammatory disorder, in which the immune system attacks the gastrointestinal tract, perhaps directed by certain microbial antigens. The group appears not to be a pure autoimmune disease reaction, but may relate to a immunodeficiency state.

There are no medications or surgical procedures that are known to cure the diseases. Most are aimed at reduction of symptoms, maintain remissions, and try to prevent relapses. Temporary anti-inflammatory medications may improve the acute process, followed by methotrexate or thiopurine to maintain remission states. Surgery appears important in cases of perforation, abscesses, obstructions, or cancer management.

Actual occurrence is unknown, as there are more than Crohn's Disease and Ulcerative Colitis which appear related. It is estimated that more than 35,000 deaths were reported in 2010. Crohn's Disease alone appears to affect 3.2 per 1000 people in Europe and North America alone.

The usual onset of symptoms may appear before actual diagnoses are made, with typical diagnoses occurring between 15-30 years of age. Lead by abdominal pain symptoms (usually lower right quadrant) and the recurrent periods of flare and remission. Many dietary, bacterial, antimicrobials, and environmental factors receive attention, some new interest in evaluating alternative therapeutic modalities to deal of issues of immune system. Use of the immune privileged cellular agents held within the AD-cSVF is proposed to help with the inflammatory contributors as well as the modulation of inflammation which favors chronic wound healing and avascular systems. Known to provide secretory antibiotic (ll-37) contributions, some thought of pro- and anti-microbials, may prove of value in those areas specifically. Cytokine and growth factors implications at the lesion sites remain to be poorly understood, but those experienced in biocellular regenerative therapies have experienced contributions to healing and prevention of recurrences of ulcerative skin lesions.

Harvest of autologous of adipose-derived tissue stromal vascular fraction (AD-tSVF) is a proven rich resource of microvascular stem/stromal cell elements with well documented growth factor and cytokine contributors. With the advent of safe, measurable, and efficacious and reproducible numbers in a closed isolation environment, the ability to isolate and concentrate a cell-only product. This AD-cSVF is capable of reintroduction into patients, via a Normal Saline Solution, via parenteral route.

This study is intended to evaluate the safety (adverse outcomes) and efficacy of using autologous cellular therapy in cases of IBD.
