About

Rheumatoid Arthritis (RA) is a chronic, autoimmune inflammatory disease that leads to significant pain, joint destruction and functional decline, and has a substantial economic impact both for sufferers and society. Although the etiology of RA is unknown, it is generally accepted that it arises from an interplay of genetic predisposition (in particular, HLA-DR allele subtypes and specific gene polymorphisms), immunological deregulation (e. g. autoantibody production), and environmental factors. The prevalence and incidence of RA in Norway is estimated to 0,4-0,5 % and 0,020-0,025 %, respectively, and incidence rates are 2-4-fold higher in women. Synovitis and bone resorption are key pathogenetic factors in RA and these patients have elevated cytokine levels in joints and blood (i.e. TNF, IL-1, IL-6). RA is also associated with significant comorbidity; the most important is premature cardiovascular disease that significantly contributes to increased mortality. Compared with the general population, mortality in RA is from 1,57-2,0-fold higher in Norway and Sweden, and their mean life expectancy is reduced by an average of 5-10 years. Medical treatment of RA consists of nonsteroidal anti-inflammatory drugs, systemic glucocorticosteroids, traditional disease modifying antirheumatic drugs (including methotrexate) and biologic therapies (including anti-tumor necrosis factor (TNF) α, anti-IL 6 and anti-CD20 therapy). Also, a considerable portion of the patients are in need of joint replacement surgery and in need of rehabilitation.

However, the treatment opportunities are still not optimal. In a large proportion of the patients, full control of the disease is not possible due to limited effect of available therapies and/or intolerance to these therapies. Therefore, there is a huge need to find new therapeutic alternatives to treat RA.

Since studies on healthy volunteers and IBD-patients support that the mushroom extract AndoSanTM exert an anti-inflammatory effect in vivo, the investigators wanted to examine in a pilot study whether this effect also was evident in patients with RA. A potential anti-inflammatory effect could prove beneficial in these seriously ill patients, who accordingly could experience less side effects (edema, granulocytopenia, diminished tissue repair) due to potential reduction number and dose of disease modifying drugs.

Full description

Main aim: Examine whether daily oral ingestion of a immunomodulatory mushroom extract (AndoSanTM) leads to a clinical, biochemical and genetical improvement in RA. The experiment will be carried out for 21 days in 15 eligible RA patients. In order to increase the scientific value of the project we will use, a as far as possible, an age matched control group of RA patients with steady medication and no intervention. The control group of 10-15 patients will be answering the same questionnaires and give the same samples of blood and feces.

Partial aims: To compare prior to (day 0) and after (day 21) daily (30 ml x 2) ingestion of Andosan the effect of this therapy on:

  • general blood samples (leucocytes, CRP, liver and renal function tests), including erythrocyte sedimentation rate (SR) and pentraxin 3 (PTX3)
  • level of blood cytokines and analytes (IL-1α/-1ra/-2/-4/-5/-6/-7/-8/-9/-10/-12(p70)/-13/-15/ 17,G-CSF,GM-CSF,MCP-1,MIP-1ß/-1α,IFNγ,TNFα and basic FGF, eotaxin, PDGF-BB, RANTES,VEGF;27-plex) -level of inflammatory marker calprotectin in feces and blood in patients
  • genetic expression in blood leukocytes (microarray) -number of swollen and tender joints, morning stiffness, Disease activity score 28 calculated by ESR (DAS28-ESR), RA impact of disease score (RAID), Health Assessment Questionnaire (HAQ), visual analogue scale (VAS) for patient's and physician's global assessment of disease activity, life quality (SF-36 version 2), fatigue score.
