IBD+TNF AB ≠ PD?

The cryptic title of this post will hopefully make sense by the time you have finished reading the material present here.

This week, new research from the USA points towards an increased risk of Parkinson’s (PD) for people that suffer from inflammatory bowel disease (IBD). 

That same research, however, also points towards a clinically available treatment that appears to reduce the risk of Parkinson’s in individuals affected by inflammatory bowel disease. That treatment being: anti–tumor necrosis factor antibodies (TNF AB). Is that title making sense yet? If not, read on.

In today’s post, we will outline what inflammatory bowel disease is, review what the new research found, and discuss what is known about TNF in Parkinson’s.

Inflammatory bowel disease (or IBD) is one of these umbrella terms that is used to refer to a group of inflammatory conditions of the large and small intestine:

The symptoms of IBD can include abdominal pain, diarrhoea, vomiting, rectal bleeding, severe internal cramps/muscle spasms in the region of the pelvis, and weight loss.

The most common forms of IBD are Crohn’s disease and ulcerative colitis.

There has been an increased incidence of IBD since World War II, which could be associated with increased awareness and reporting of the condition, but it could also be linked with increases in meat consumption (Click here to read more about this). For example, in 2015, an estimated 1.3% of U.S. adults (3 million) were diagnosed with IBD, which was a large increase on the levels in 1999 (0.9% or 2 million adults – Source: CDC).

This is delightful, but what does it have to do with Parkinson’s?

So this week, an interesting study was published on the Journal of the American Medical Association – Neurology edition website:
