An MRI Showed My Sigmoid Colon Wall Was Thickened and Inflamed

Page 2: TEDMED 2013 Talk

I Got a Copy of My MRI Data &

Used Calit2 Software to Enable Me

to Fly Through My Internal Organs

Page 3: TEDMED 2013 Talk

I Searched for Clues AmongMy 150 Blood and Stool Variables, Each Graphed Over 5-10 Years

Calit2 64 megapixel VROOM

Page 4: TEDMED 2013 Talk

Only One Variable Was Far Out of Norm-Complex Reactive Protein From Blood Sample

Normal Range<1 mg/L

Normal

27x Upper Limit

CRP Indicates Chronic Episodic Inflammation

Page 5: TEDMED 2013 Talk

By Looking at Stool Samples Over Time I Discovered My Lactoferrin Was Very Far Above Normal

Normal Range<7.3 µg/mL

124x Upper Limit

Lactoferrin Is an Indicator of White Blood Cells Attacking Your Colon

Page 6: TEDMED 2013 Talk

High Lactoferrin Biomarker Values Led Me to HypothesizeI Had Inflammatory Bowel Disease (IBD)

My Values 2009-10

My Values May 2011

Scand J Gastroenterol. 42, 1440-4 (2007)

IBD is an Autoimmune Disease Which Comes in Two Subtypes: Crohn’s Disease and Ulcerative Colitis

When We Think About Biological DiversityWe Typically Think of the Wide Range of Animals

But All These Animals Are in One SubPhylum Vertebrataof the Chordata Phylum

We Found Major Shifts in Microbial Ecology PhylaBetween Healthy and Two Forms of IBD

Collapse of Bacteroidetes

Explosion of Proteobacteria

Most Common Microbial

Phyla

Microbiome “Dysbiosis”or “Mass Extinction”?

Page 15: TEDMED 2013 Talk

I Can Track Changes in My Microbiome Before and After 1 Month Antibiotic & 2 Month Prednisone Therapy

Therapy Greatly Reduced Two Phyla,But Massive Reduction in Bacteroidetes

And Large % Proteobacteria Remain

Reduced 45x

Reduced 90x

Small Changes With No Therapy

I am Trapped in a Local Ecological Equilibrium“Far from Home”

Refining the Dance

• I Now Know Where I Am

• And Where I Need to Get to• Startups Enable Tracking the Dance

• Novel Interventions Become Possible

Where There is DataThere is Hope
