Abstract

Disclosed is a method of diagnosing autoimmune diseases, such as multiple sclerosis and systemic lupus erythematosus, which involves detecting the presence of small intestinal bacterial overgrowth (SIBO) in a human subject having at least one symptom associated with a suspected diagnosis an autoimmune disease. Also disclosed is a method of treating these autoimmune diseases, which involves at least partially eradicating a SIBO condition in the human subject. The method includes administration of antimicrobial or probiotic agents, or normalizing intestinal motility by employing a prokinetic agent. Also disclosed is a kit for the diagnosis or treatment of autoimmune diseases.

Claims

1. A method of treating an autoimmune disease in a subject having small intestinal bacterial overgrowth and a symptom associated with a suspected diagnosis of the autoimmune disease, comprising:

providing a composition comprising an antimicrobial agent or a probiotic agent; and

;

administering the composition to the subject to at least partially eradicate small intestinal bacterial overgrowth and the symptom is improved.

2. The method of claim 1, further comprising:

detecting the presence of small intestinal bacterial overgrowth in the subject.

3. The method of claim 1, wherein the autoimmune disease is multiple sclerosis or systemic lupus erythematosus.

4. The method of claim 1, wherein the antimicrobial agent is selected from the group consisting of neomycin, metronidazole, teicoplanin, ciprofloxacin, doxycycline, tetracycline, augmentin, cephalexin, penicillin, ampicillin, kanamycin, rifamycin, rifaximin, vancomycin, and combinations thereof.

5. The method of claim 1, wherein the antimicrobial agent is rifaximin.

6. The method of claim 1, further comprising administering to said human subject an anti-inflammatory cytokine , substantially simultaneously with or after at least partially eradicating small intestinal bacterial overgrowth in the human subject.
