BACKGROUND
Accumulating evidence shows that interleukin(IL)-1 plays a critical role in inflammation and connective tissue destruction observed in both osteoarthritis and rheumatoid arthritis. IL-1 induces gene expression related to cytokines, chemokines and matrix metalloproteinases by activation of many different transcription factors. MATERIALS AND METHODS: The chondrosarcoma cell line, SW1353, is known to be a valuable in vitro system for investigating catabolic gene regulation by IL-1beta in chondrocytic cells. To explore and analyze the changes in gene expression by IL-1 responsible for arthritis, SW1353 was treated with IL-1 for 1, 6 and 24 h and then total RNAs were purified for each time. The changes in gene expression were analyzed with 17k human cDNA microarrays and validated by semi-quantitative RT-PCR. RESULTS: Greater than a two-fold change was observed in 1,200 genes including metallothioneins, matrix metalloproteinases, extracellular matrix proteins, antioxidant proteins, cytoskeleton proteins, cell cycle regulatory proteins, proteins for cell growth and apoptosis, signaling proteins and transcription factors. These changes appeared to be correlate with the pathophysiological changes observed in early osteoarthritis. CONCLUSION: cDNA microarray analysis revealed a marked variability in gene expression, and provided insight into the overall molecular changes. The result of this study provide initial information for further studies to identify therapeutic targets in osteoarthritis pathogenesis.

AbstractAbstract PDF
Generalized edema and hypoalbuminemia are relatively common presenting manifestations in many clinical situations. The differential diagnosis of hypoalbuminemia include: Kwashiorkor, synthetic dysfunction of the liver, and excessive protein loss as in nephrotic syndrome. In systemic lupus erythematosus (SLE), hypoalbuminemia and generalized edema are most commonly due to protein loss associated with lupus nephritis; gastrointestinal involvement is uncommon, and therefore protein loss through the gastrointestinal tract is quite rare. We report a case of a protein losing enteropathy (PLE) associated with SLE. The patient was referred to our hospital for generalized edema, arthralgia and facial rash. After clinical evaluation, the patient met the criteria for the SLE diagnosis; hypoalbuminemia with general edema was consistent with a protein losing enteropathy. After two weeks of therapy with parenteral high dose glucocorticoid, the patients was improved in laboratory findings as well as clinical symptoms.

AbstractAbstract PDF
Pyoderma gangrenosum is uncommon neutrophilic dermatosis characterized by richness of the mature neutrophilic polynuclear dermal infiltrate. Pyoderma gangrenosum is associated with variable diseases, most commonly inflammatory bowel disease, hematological diseases, malignancies, but it is reported rarely in rheumatoid arthritis. We report a case of pyoderma gangrenosum in rheumoid arthritis patient. A 50-year-old woman admitted to our hospital due to painful pretibial ulcerative skin lesions. She had been treated as rheumatoid arthritis for 8 years. At admission, body temperature was 36.5degrees C and other vital sign was unremarkable. Physical examination revealed right pretibial ulceration, multiple pustules on left pretibial area and both palms. Laboratory studies revealed WBC count 7,600/uL (neutrophils 60.3%, eosinophil 3.2%), hemoglobin 11.4 g/dL, platelet count 319,000/uL, ESR 65 mm/hour. Other lab findings were also unremarkable. Skin biopsy was done, which showed dense dermal infiltrate of neutrophils and wound culture were negative. By 8 weeks after systemic high dose corticosteroid (1 mg/kg/day), cyclosporine A (5 mg/kg/day), sulfasalazine 2 g therapy, symptoms and skin ulceration were being improved. Without skin relapse, she is followed up our hospital with low dose corticosteroid and sulfasalazine.
