Gut microbiome-Skin Axis

It was found the Campylobacter bacteria to be very much abundant in patients with rosacea. Interestingly, the same bacteria have also been implicated many times in the gut microbiome in patients with ulcerative colitis and other GI diseases. Perhaps this indicates similar pathogenesis and explains why we often see GI diseases in rosacea. 

Prevotella bacteria, which have been linked to cardiovascular conditions including atherosclerotic plaques, were also found to be increased in the microbiome of rosacea skin. This may contribute to the increased association of cardiovascular disorders in rosacea patients. Past reports have shown that Acinetobacter bacteria help patients with atopic dermatitis and those with allergic and atopic tendencies. Interestingly, Acinetobacter bacteria were found to be very low in the skin of rosacea patients, which may explain why allergic diseases tend to be more commonly seen in rosacea patients.
