Objective. To investigate the effect of the fermented wheat germ extract (FWGE ®) in patients with severe rheumatoid arthritis (RA). Methods. Fifteen female RA (Steinbrocker II-III) patients, who had unsuccesfully tried two different DMARD treatments, were enrolled in an open-label, 1-year long, pilot clinical study. DMARD and steroid therapies were recorded and continued. All patients received FWGE ® as additional therapy. For measurement of efficacy the Ritchie Index, the Health Assessment Questionnaire (HAQ) and the assessment of morning stiffness were applied. Patients were evaluated at baseline, 6 and 12 months. For statistical analyses the Wilcoxon test was used. Results. At both 6 and 12 months, Ritchie index, HAQ and morning stiffness showed significant improvements compared with the baseline values. Dosages of steroids could be reduced in about half of the patients. No side effects of FWGE ® were observed. Conclusion. Supplementation of standard therapies with a continuous administration of FWGE ® is beneficial for RA patients

 All patients had to previously failed at least two disease-modifying antirheumatic drug (DMARD) therapies due to either side effects or inefficacy. In all patients, at least one DMARD treatment had to be regarded as ineffective. If the ongoing DMARD treatment had been given for four consequtive months without any benefit, it was considered as ineffective. Exclusion criteria included: age less than 18, or more than 80 years; severe liver, kidney or hematological disorders; active gastric or duodenal ulcer; psychiatric disease or mental retardation. Patients were planned to continue their DMARD and steroid therapies, while receiving 2 x single dosage of FWGE ® per day as additional therapy. A single dosage of the medical food contained 8.5 g pure FWGE plus arome and sweetener, prepared as a ready to drink mix shake and, should be consumed before meals. Measurement of efficacy: the Ritchie Index, comprising 52 joints, which is still considered a reliable tool of quantitative joint assessment (6) was used in this study. For the description of the patient reported outcomes, the Stanford Arthritis Center’s Health Assessment Questionnaire (HAQ) (7) was employed. Morning stiffness assessment was carried out by using a rating scale (8). Laboratory (sedimentation rate, CRP, liver and kidney function tests) as well as hematological parameters (hemoglobin, hematocrit) were obtained by standard procedures. Patients were evaluated at baseline and, 6 and 12 months afterwards. Ongoing DMARD and steroid therapies were recorded and continued. DMARD therapy was reduced if the Ritchie Index plus either the sedimentation rate or the CRP had been reduced by 20% at least for two months.

 For statistical analyses the Wilcoxon test, where P < 0.05 indicated a statistical significance, was used. Patients gave written informed consent, and the Regional Committee of the National Council of Health approved the protocol. The Declaration of Helsinki principles had been followed, and the patients were free to withdraw their consent at any time during the study. Results In Budapest, at the National Institute of Rheumatology and Physiotherapy, 15 refractory RA patients (ambulatory female patients; average age 54, range 44-68 years), whose disease was in Steinbrocker anatomical and functional categories of II and III, were enrolled in this open-label, non-randomized, pilot study. The average duration of their disease was 8.2 (range 3-25) years. All but one patient were seropositive. At the time of entry, 8 patients received DMARD (methotrexate/4, cyclosporine/3, chloroquine) plus corticosteroid (methylprednisolone/5, prednisolone/2, triamcinolone), while 2 patients received DMARD (methotrexate, sulfasalazine), and 3 patients received corticosteroid (methylprednisolone, prednisolone, dexamethasone) therapies alone. By the end of the first 6 months of the study, the steroid dosage could be decreased in 5, and remained unchanged in 6 patients (significant change) (Fig. 1). By the end of the 12th months, it remained unchanged in 6, was decreased in 4, and was increased in 1 patient (not significant change). In 6 patients, the DMARD therapy remained unchanged during the whole study and, it was reduced in 3, increased in 1 patient (not significant change). 

 It has been established that an apoptotic pathway can be initiated through the activation of the caspase downstream proteases, including the cleavage of the poly(ADP-ribose) polymerase (PARP) enzyme, which is considered to be a hallmark of activation of caspase-3 like proteases during apoptosis, thus leading to genomic instabilities and disintegration in the target cells. FWGE ® induced proteolysis of PARP shown by Western blots of extracts prepared from Jurkat leukemia cells treated with FWGE and probed with anti-PARP antibody (10). As this preparation has further been demonstrated to induce apoptosis in other cancer cell lines (11-13), it seems plausible to hypothesize its anti-RA efficacy by this mechanism. Recently, it has also been shown that FWGE ® is a strong but, non-selective inhibitor of the cyclooxygenases 1 and 2 (14). In fact, for reasons we still do not know, on long term, however, we could not observe such anti-inflammatory manifestations in the values of the systemic inflammation-related macroscopic hematology parameters, such as in the sedimentation rate and CRP. Previous oral toxicity studies showed that unlike corticosteroids or nonsteroidal anti-inflammatory drugs (NSAIDs), FWGE ® does not exert any toxic effect (15). Since the benefits of this medical food have became steady during the 12 months long treatment in patients, whose former therapy with two DMARDs had otherwise failed, FWGE ® could be implemented as a suitable adjunctive therapeutic tool in the treatment of RA.
