Effectiveness of etanercept vs cyclophosphamide as treatment for patients with amyloid A amyloidosis secondary to rheumatoid arthritis.

Objectives: To compare the effectiveness of an alkylating agent with that of a biologic agent in the treatment of patients with amyloid A (AA) amyloidosis secondary to RA and to assess the association of the serum AA (SAA) 1.3 allele with treatment.

Methods: CYC and etanercept (ETN) were administered to 62 and 24 RA patients, respectively, who were confirmed with biopsy as having AA amyloidosis.

Cutaneous nodules in patients with rheumatoid arthritis: a case report and review of literatures.

We report a case of 57-year-old Japanese woman with an overlap syndrome of both rheumatoid arthritis (RA) and autoimmune hepatitis, who developed multiple skin nodules. An extensive biopsies of the nodules revealed rheumatoid neutrophilic dermatitis, showing panniculitis without vasculitis, combining with granulomatous formation histopathologically. Since cutaneous nodules in patients with RA are very complex, differential diagnosis should be done according to disease activities, medications used, and pathological findings.

Etanercept can induce resolution of renal deterioration in patients with amyloid A amyloidosis secondary to rheumatoid arthritis.

The benefit of biological therapies in rheumatoid arthritis (RA) treatment is well known, but their role in amyloid A (AA) amyloidosis secondary to RA is unclear. The aim of this study was to clarify the clinical benefit of etanercept in RA patients with AA amyloidosis. We treated 14 RA patients who had serum amyloid A protein (SAA) 1.

CD8+ T lymphocytes infiltrate predominantly in the inflammatory foci of MPO-ANCA-positive thoracic hypertrophic pachymeningitis in a patient with HLA-A24.

Hypertrophic pachymeningitis (HP) is extremely rare and an inflammatory process that thickens the dura mater. A 59-year-old Japanese woman developed backache, became paraplegic, and magnetic resonance imaging revealed diffuse thickening of the thoracic dura mater encompassing the spinal cord. Although a test for myeloperoxidase antineutrophil cytoplasmic autoantibody (MPO-ANCA) was shown to be positive, vasculitis was not found and CD8(+) T lymphocytes that predominated in the inflammatory foci.

A study of ten Japanese patients with seronegative spondylarthropathy: a tentative proposal.

We reviewed ten patients with seronegative spondylarthropathy (SNSA), who all fulfilled the European Spondylarthropathy Study Group criteria for spondylarthropathy (SpA); seven patients also met the Amor criteria for SpA. Seronegative spondylarthropathy was not a uniform syndrome but rather a wide spectrum of complex disease with characteristics of sacroiliitis and enthesopathy. The most frequent symptom at diagnosis of SNSA was inflammatory low back pain, followed by asymmetric oligoarthralgia and Achilles tendonitis and/or plantar fasciitis.

Primary biliary cirrhosis (PBC)-CREST overlap syndrome with coexistence of Sjögren's syndrome and thyroid dysfunction.

Calcinosis, Raynaud's phenomenon, oesophageal dysmotility, sclerodactyly, telangiectasia (CREST) syndrome, a limited form of systemic sclerosis, is sometimes complicated by primary biliary cirrhosis (PBC). A 52- and 61-year-old Japanese woman with PBC-CREST overlap syndrome accompanied by Sjögren's syndrome, and Hashimoto's thyroiditis, and Graves' disease, respectively, are reported. They had suffered from Raynaud's phenomena, sclerodactyly, morning stiffness, arthralgia, and sicca symptoms during these several years.
