- Public TitleObservational study;
Mycophenolate sodium (Myfortic) in primary Sjogren’s syndrome.
- hypothesisMycophenolate is a selective inhibitor of inosine-monophosphate-dehydrogenase which leads to inhibition of the de novo pathway of nucleotide synthesis. The antiproliferative effect of mycophenolate mainly affects activated T- and B-lymphocytes because the proliferation of these cells is critically dependent on the de novo purine synthesis compared to other eukaryotic cells. Since these lymphocytes have been suggested to play a pivotal role in the inflammation and immunopathogenesis of primary Sjogren's syndrome, mycophenolate might be a promising agent in the treatment of pSS.

- Target number of participants11
- InterventionsThe dosage of mycophenolate sodium shoud increase weekly by 360mg up to a maximum stable dose of 1440 mg daily. In patients not well tolerating the drug the dosage can be reduced to 720 mg per day. Follow up visits will be after 4 week,
12 weeks and 24 weeks
- Primary outcomeTo evaluate the efficacy of mycophneolate sodium treatment in patients with pSS refractory to other immunosuppressive agents.
Outcome measures:
Glandular function tests, questionnaires, and laboratory tests at baseline, after 4 weeks, week 12, at week 24.
The lachrymal gland function will be assessed by unanesthetized Schirmer’s test.
In addition, we will collected and weighed the unstimulated whole saliva throughout 5 minutes.
Visual analoge scale for the severity of ocular dryness, arthralgia, and fatigue on a 100-mm visual analogue scale (VAS) ranging from 0 to 100.
Outcome will also be determined by the Short Form-36 (SF-36). In addition, the Health Assessment Questionnaire (HAQ) has to be completed Levels of immunoglobulins (IgG, IgM and IgA), RF-IgM as well as serum concentrations of complement levels (C3 and C4) will be measured during the trial. Also IgG antibodies to SS-A and SS-B will be analysed.
- Secondary outcomeSafety of mycophenolate sodium treatment in patients with pSS:
Outcome measures:
History-taking including, clinical examination.
At each clinical visit, the patients will be asked about possible adverse events.
Laboratory tests at baseline, after 4 weeks, week 12, at week 24.(i.e. ESR, C-reactive protein (CRP), renal and liver function tests, total protein, and full blood count).

- Brief summaryPrimary Sjogren’s syndrome (pSS) is an autoimmune disorder characterized by keratoconjunctivitis sicca and xerostomia. In addition, various extraglandular manifestations may develop. Several immunomodulating agents have been attempted in the treatment of pSS without achieving satisfactory results. Currently, there is no approved systemic treatment for pSS.
Since activation of lymphocytes is a key element in the pathogenesis of the disease inhibition of lymphocyte activation might be beneficial in the treatment of pSS. Mycophenolic acid has anti-proliferative effects on B- and T-cells. Mycophenolate containing compounds such as mycophenolate mofetil (MMF) and enteric coated mycophenolate sodium (MPS) are immunosuppressive drugs approved for the prevention of transplant rejection. MPS 720 mg and MMF 1000 mg deliver nearly equimolar doses of the active immunosuppressive agent. Although no controlled study has been performed so far mycophenoate has been suggested as sole or adjuvant treatment for primary Sjogren's syndrome pSS in a recent review articles.
The recent observations and the immunosuppressive effect of mycopenolate sodium in other autoimmune diseases led us to evaluate the efficacy and safety of Mycophenolate sodium treatment in patients with pSS refractory to other immunosuppressive agents.
