Lupus erythematosus is a chronic autoimmune disease characterized by remissions and exacerbations. Accumulated evidence indicated that matrix metalloproteinases (MMPs) are upregulated in inflammatory cells of cutaneous lupus erythematosus (CLE); however, the activity levels of these proteases have remained uncharacterized. To elucidate the significance of MMP-2, MMP-9, and TIMP-1 in CLE pathogenesis, gelatin zymography was used to investigate pro and active levels of MMP-2 and MMP-9 in lesional and perilesional skin biopsies obtained from twenty-two CLE patients...

BACKGROUND: Methotrexate (MTX) remains the anchor drug in rheumatoid arthritis (RA) treatment, but is poorly tolerated or contraindicated in some patients. There is a wealth of data supporting the use of abatacept in combination with MTX, but data on alternative conventional synthetic disease-modifying antirheumatic drug (csDMARD) combinations with abatacept are scarce. METHODS: In this post-hoc exploratory analysis, efficacy and safety data were extracted from abatacept RA studies in which combination with csDMARDs other than MTX was permitted: three interventional trials (ATTAIN, ASSURE, and ARRIVE) and one real-world study (ACTION)...

Antiphospholipid syndrome (APS) is an autoimmune disease characterized by the presence of antiphospholipid antibodies, such as lupus anticoagulant, anticardiolipin antibodies and anti-β2-glycoprotein 1 antibodies. APS can present with a variety of clinical phenotypes, including thrombosis in the veins, arteries and microvasculature as well as obstetrical complications. The pathophysiological hallmark is thrombosis, but other factors such as complement activation might be important. Prevention of thrombotic manifestations associated with APS includes lifestyle changes and, in individuals at high risk, low-dose aspirin...

Lupus is an autoimmune disease affecting the connective tissue. Its clinical and biological polymorphism is often misunderstood by patients and families and can lead to treatment interruption and a decision to turn to alternative medicine. We used a questionnaire to assess the degree of knowledge of this disease of family members living with lupus patients. Of the 56 lupus patients receiving regular follow-up at our hospital, 123 members of 30 of their families (53.5%) participated. Overall, among these families, 81...

Kikuchi-Fujimoto disease, also known as histiocytic necrotizing lymphadenitis, is a syndrome characterized by the presence of usually painful cervical lymphadenopathy with fever and night sweats. It is a rare clinical entity that mainly affects young Asian women, although it found worldwide. It is a benign and self-limiting condition; however, its importance lies in its differential diagnosis with other clinical entities such as lymphoma or histiocytoma. We present a case of Kikuchi-Fujimoto disease, with special emphasis on its clinicopathological significance and its evolution during outbreaks...
