Uric acid and gout as reflections of dysbiosis

Better blood and urine ranges of uric acid may cause gout (painful uric acid crystal deposition in joints) and kidney illness. Extra just lately, uric acid has additionally been related to elevated threat for metabolic syndrome, sort 2 diabetes, heart problems, kidney and liver illness even within the absence of gout assaults, i.e., “asymptomatic hyperuricemia” or asymptomatic will increase in blood ranges of uric acid. Standard “remedies” contain lowering the dietary consumption of purines, i.e., the genetic (DNA and RNA) materials current in animal merchandise, and prescription drugs that block the enzyme, xanthine oxidase, that yields uric acid. As in so many different situations, the standard options tackle “downstream” phenomena however fail to handle the precise trigger—not weight-reduction plan, however disruptions of bowel flora composition with lack of microbial species which are vigorous in metabolizing uric acid, thereby lowering blood and urine ranges. This science has been unfolding for in regards to the previous decade, but it surely has just lately galloped ahead with a flood of recent observations which are yielding therapeutic prospects in managing uric acid. (It additionally addresses a elementary flaw in standard pondering: Why would people, genetically-adapted over three million years to consuming animal merchandise akin to meats, organs, and seafood, develop an intolerance to them? The issue is just not animal merchandise; it’s the capability to metabolize parts akin to uric acid, disrupted by shifts in gastrointestinal (G) microbiome composition as a consequence of trendy life and maybe worsened by a nutrient- and polyphenol-poor trendy weight-reduction plan.)

Individuals with gout and hyperuricemia have been proven to have 1) disrupted gastrointestinal microbiome composition with elevated Proteobacteria (fecal species) and mucin-degraders akin to Bacteroides caccae, 2) elevated intestinal permeability, and three) elevated endotoxemia, all of which additional provides to irritation, insulin resistance, and susceptibility to heart problems. You’ll be able to respect that gout and hyperuricemia should not nearly uric acid, however a constellation of phenomena, a lot of which will be backtracked to a disrupted GI microbiome.

The listing of gastrointestinal microbes that metabolize uric acid in varied methods is rising quickly, principally Lactobacillus species which have advanced to be environment friendly metabolizers of purines and different genetic materials. Among the many species/strains which were related to lowered blood and urinary ranges of uric acid embody:

  • Lactobacillus brevis DSM9218
  • Lactobacillus plantarum WCFS1
  • Lactobacillus paracasei S12
  • Limosilactobacillus fermentum GR-3
  • Lacticaseibacillus paracasei MJM60396
  • Ligillactobacillus salivarius CECT 30632

A human examine of the final microbe listed, L. salivarius CECT 30632 at a every day dose of 1 billion CFUs per day for six months, demonstrated a marked discount in gout episodes, reliance on gout medicine, and lowered blood ranges of uric acid in comparison with placebo.

Along with over proliferation of fecal microbes and mucin-degrading species, lack of vital butyrate-producing species, Faecalibacterium prausnitzii and Bifidobacteria species, has additionally been documented. Though F. prausnitzii and Bifidobacteria species don’t themselves metabolize uric acid, they by some means assist those who do. Recall that prebiotic fibers akin to inulin/FOS trigger a “bloom” in these species, which will additionally add additional benefit. Additional, microbial metabolism of purines and different genetic materials is considerably elevated when glucose (sugar) is much less accessible; in different phrases, a scenario during which insulin resistance and blood glucose are introduced beneath management might additional improve the microbiome’s capability to rid your physique of purines and thereby uric acid.

After all, you might attempt to get hold of and ferment a few of these species, as we do with our L. reuteri and L. gasseri yogurts to acquire excessive bacterial counts to make sure significant organic results akin to eradication of SIBO, smoother pores and skin, elevated libido, lowered intestinal permeability and decreased endotoxemia. However, as you possibly can respect, it turns into impractical to ferment every species we need to colonize our GI tracts. Curiously, nearly all of species that metabolize purines and thereby cut back uric acid come from fermented meals akin to sauerkraut, pickles, and kimchi. Maybe in future we will get hold of a number of of these microbes akin to L. salivarius CECT 30632 that you might ferment as yogurt to amplify uric acid-reducing results. There may be sometimes a a number of 12 months lag going from laboratory statement to business availability, so these microbial strains should not but accessible. Keep tuned.

By the best way, uric acid is just not the one issue that’s proving to be a metabolic consequence of a disrupted gastrointestinal microbiome. Add oxalates, homocysteine, vitamin B12 deficiency, folate deficiency and a variety of different conditions which are yielding to insights into the microbiome that, like uric acid, ought to trigger us to rethink all we thought we knew about these phenomena.
