Stem Cell Therapy in Perianal Fistula Associated with Crohn’s Disease

Highlights:

Perianal fistula is most commonly reported in patients suffering from Crohn’s disease can be treated effectively by a new therapy involving Darvadstrocel.
Darvadstrocel by its expanded adipose stem cells acts in the inflammatory pathways and reduces inflammation.
The healing process is improved significantly while Darvadstrocel is administered and should be used while other treatments are failed to respond in treating perianal fistula.

Perianal fistula is an inflammatory condition which usually affects the area surrounding the anal canal by its presence of fistulous tract found across the anal sphincters. The presence of diseases either of colonic or rectal origin is found to be a serious threat to the development of such perianal fistulas.

Darvadstrocel shows its benefit by improving the healing process of complex perianal fistulas in patients suffering from Crohn's disease. It comes as an injection form which contains expanded adipose stem cells about 5 million cells/ml. After the administration of Darvadstrocel, it decreases the release of pro-inflammatory cytokines at the inflammation sites. Due to this immunoregulatory activity, inflammation is greatly reduced which helps the tissues around the fistula to heal quickly.

The European Medicines Agency (EMA) had approved Darvadstrocel stem cell therapy in treating adult patients with perianal fistula presented with a non-active or mildly active luminal Crohn's disease, only when other treatment choices showed no response.

‘Crohn’s disease patients who suffer from a common complication of perianal fistula are treated with a new advanced treatment containing Darvadstrocel which offers quick healing process by interfering with the inflammatory mediators. ’

It is highly recommended that only medical specialists should be engaged in selecting Darvadstrocel therapy or those who are experienced in diagnosing and treating the conditions where Darvadstrocel is intended to be used for. Although the success rate in healing perianal fistula is higher with this new advanced therapy, the most commonly reported adverse effects are the anal abscess, fistula, pain due to a muscle spasm in the anal area along with a procedural pain.

Crohn's disease

Crohn's disease is one of the diseases of Inflammatory bowel disease that occurs due to the inflammation of the digestive tract which affects any part of the mouth to anus. It commonly affects the lower section of the small intestine known as the ileum.

The causative origin of Crohn's disease is not known but believed to occur due to the abnormal reaction of the body immune system. There is no proper treatment for Crohn's disease but the symptoms can be treated accordingly.

It is estimated that nearly 115,000 people in the U.K alone and more than a million are affected worldwide by this disease.

Inflammatory Bowel Disease

Inflammatory bowel disease involves chronic inflammation of the colon and small intestine. Symptoms include diarrhea, abdominal pain and weight loss.

Ulcerative Colitis

Ulcerative colitis is characterized by bouts of diarrhea, bleeding per rectum and pain, which remits and relapses. Fulminant colitis is a possibility, which may require colectomy.

Bone Marrow Transplantation

Preferred Term is Hematopoietic stem cell transplantation. In this stem cell from bone marrow are injected into a recipient after treating them with growth factor.
