Abstract: OBJECTIVES: To develop Portuguese evidence-based recommendations for the use of methotrexate (MTX) in daily clinical practice in rheumatic disorders. METHODS: The Portuguese project was integrated in the multinational 3E Initiative (Evidence, Expertise, Exchange) 2007-2008 where a total of 751 rheumatologists from 17 countries have participated. Ten clinical questions concerning the use of MTX in rheumatic diseases were formulated and the Portuguese group added three more questions. A systematic literature search in Medline, Embase, Cochrane Library and 2005-2007 ACR/EULAR meeting abstracts was conducted. Selected articles were systematically reviewed and the evidence was appraised according to the Oxford Levels of Evidence. In Portugal, a national meeting was held in Obidos on February 15th and 16th, 2008, involving 50 rheumatologists who discussed and voted by Dephi method the recommendations. Finally, the agreement among the rheumatologists and the potential impact on their clinical practice was assessed. RESULTS: Thirteen national key recommendations on the use of MTX were formulated: work-up before starting MTX, optimal dosage and route of administration, use of folic acid, monitoring, management of hepatotoxicity, long-term safety, mono versus combination therapy, management in the peri-operative period, during infections, before/during pregnancy and after clinical remission, screening and treatment of tuberculosis and the role of MTX as a steroid-sparing agent in rheumatic diseases. DISCUSSION: The Portuguese recommendations for the use of MTX in daily clinical practice were developed, which are evidence-based and supported by a panel of 50 rheumatologists, enhancing their validity and practical use. This project was integrated in a multinational initiative that led to the recent publication of ten multinational recommendations which differ from ours in some specific aspects.

Abstract: BACKGROUND: A 31-year-old woman presented with a 5-year history of painful ulcerations, palpable purpura, porcelain-white atrophic scars of the malleolar region and dorsal aspect of the feet, livedo reticularis on the limbs, arthralgia, xerophthalmia, and xerostomia. METHODS: Skin biopsy revealed vessel wall hyalinization and thrombosis of the microvasculature with a very scarce dermal inflammatory infiltrate. Biopsy of the oral mucosa showed mononuclear infiltration of an intralobular duct of a salivary gland. RESULTS: Laboratory studies, including autoantibodies and inflammation markers, were normal, except for a positive rheumatoid factor. Coagulation screening revealed C677T methylenetetrahydrofolate reductase (MTHFR) mutation, with a normal serum homocysteine. The patient was treated with oral methylprednisolone (32 mg/day with progressive reduction) and enoxaparin (20 mg/day subcutaneously), with complete ulcer healing within 4 months. CONCLUSION: Livedoid vasculitis or vasculopathy has not been referred to previously in association with Sjögren's syndrome, but may be associated with other autoimmune disorders and anomalies of coagulation, namely factor V Leiden mutation, protein C deficiency, and MTHFR mutation, associated or not with hyperhomocysteinemia, a condition that seems to confer an increased risk of recurrent arterial and venous thrombosis. We stress the importance of anticoagulant therapy for ulcer healing and for the prevention of other thrombotic events.
