Delve into the world of microbiome and immunological biomarkers to understand Inflammatory Bowel Disease (IBD) through a detailed analysis of microbial ecology and immune system responses over time.

An MRI Showed My Sigmoid Colon Wall Was Thickened and Inflamed
I Got a Copy of My MRI Data &Used Calit2 Software to Enable Me to Fly Through My Internal Organs
I Searched for Clues AmongMy 150 Blood and Stool Variables, Each Graphed Over 5-10 Years Calit2 64 megapixel VROOM
Only One Variable Was Far Out of Norm-Complex Reactive Protein From Blood Sample 27x Upper Limit Normal Range <1 mg/L Normal CRP Indicates Chronic Episodic Inflammation
By Looking at Stool Samples Over Time I Discovered My Lactoferrin Was Very Far Above Normal 124x Upper Limit Normal Range <7.3 µg/mL Lactoferrin Is an Indicator of White Blood Cells Attacking Your Colon
High Lactoferrin Biomarker Values Led Me to HypothesizeI Had Inflammatory Bowel Disease (IBD) Scand J Gastroenterol. 42, 1440-4 (2007) My Values 2009-10 My Values May 2011 IBD is an Autoimmune Disease Which Comes in Two Subtypes: Crohn’s Disease and Ulcerative Colitis

We Found Major Shifts in Microbial Ecology PhylaBetween Healthy and Two Forms of IBD Most Common Microbial Phyla Microbiome “Dysbiosis” or “Mass Extinction”? Collapse of Bacteroidetes Explosion of Proteobacteria
I Can Track Changes in My Microbiome Before and After 1 Month Antibiotic & 2 Month Prednisone Therapy Reduced 45x Reduced 90x Therapy Greatly Reduced Two Phyla, But Massive Reduction in Bacteroidetes And Large % Proteobacteria Remain 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 Data There is Hope
