OBJECTIVE: To investigate the effects of avocado (A)/soybean (S) unsaponifiables on the metabolism of human osteoarthritic (OA) chondrocytes cultured in alginate beads over 12 days. METHODS: Enzymatically isolated OA chondrocytes were cultured in alginate beads in a well defined culture medium for 12 days, in the presence or not of 10-10 M interleukin 1beta (IL-1beta). DNA content was measured using a fluorometric method. Production of aggrecan (AGG), stromelysin-1 (MMP-3), tissue inhibitor of metalloproteinases-1 (TIMP-1), macrophage inflammatory protein-1beta (MIP-1beta), IL-6, and IL-8 were assayed by specific enzyme amplified sensitivity immunoassays. Prostaglandin (PG) E2 was measured by a specific radioimmunoassay and nitrite by a spectrophotometric method based on the Griess reaction. A commercial avocado and soybean mixture of unsaponifiables (A1S2) and each component separately were tested in a range of 0.625 to 40.0 micro g/ml. RESULTS: After 12 days' incubation, A1S2 increased AGG synthesis and accumulation in alginate beads in a dose and time dependent manner. A1S2 promoted the recovery of aggrecan synthesis after 3 days of IL-1beta treatment. A1S2 was a potent inhibitor of basal and IL-1beta stimulated MMP-3 production. The procedure also weakly reversed the inhibitory effect of IL-1beta on TIMP-1 production. A1S2 inhibited basal production of MIP-1beta, IL-6, IL-8, NO*, and PGE2 by OA chondrocytes and partially counteracted the stimulating effect of IL-1 on PGE2. Compared to avocado or soybean added separately, the mixture had a superior effect on NO* and IL-8 production. CONCLUSION: A1S2 stimulated aggrecan production and restored aggrecan production after IL-1beta treatment. In parallel, A1S2 decreased MMP-3 production and stimulated TIMP-1 production. These results suggest A1S2 could have structure-modifying effects in OA by inhibiting cartilage degradation and promoting cartilage repair. [less ▲]

Objective. To determine the effects of avocado/soybean unsaponifiables (ASU) on osteoblast-induced dysregulation of chondrocyte metabolism. Methods. Human chondrocytes were isolated from osteoarthritis (OA) cartilage and cultured in alginate beads for 4 or 10 days in the absence or presence of osteoblasts isolated from nonsclerotic (NSC) or sclerotic (SC) zones of OA subchondral bone plate in monolayer. Before co-culture, osteoblasts were incubated or not with 10 mu g/ml ASU for 72 hours. Aggrecan, type 11 collagen, matrix metalloproteinase-3 (MMP-3) and MMP-13, tissue inhibitor of metalloproteinase (TIMP-1), transforming growth factor-beta 1 (TGF-beta 1) and TGF-beta 3, inducible NO synthase (iNOS), and cyclooxygenase-2 (COX-2) mRNA levels in chondrocytes were quantified by RT-PCR. Aggrecan, osteocalcin, TGF-beta 1, interleukin 18 (IL-1 beta), and IL-6 production were assayed by inummoassays. Results. In co-culture, SC osteoblasts induced a significant inhibition of matrix protein production and a significant increase of MMP synthesis by chondrocytes. In contrast, SC osteoblasts did not modify TIMP-1, TGF-beta 1 and TGF-beta 3, iNOS, or COX-2 mRNA levels in chondrocytes. The pretreatment of SC osteoblasts with ASU fully prevented the inhibitory effects of SC osteoblasts on matrix component production, and even significantly increased type 11 collagen mRNA level over the control (chondrocytes alone) value. In contrast, pretreatment of SC osteoblasts with ASU did not significantly modify the expression of NIMP, TIMP-1, TGF-beta 1, TGF-beta 3, iNOS, or COX-2 gene by chondrocytes. Conclusion. ASU prevent the osteoarthritic osteoblast-induced inhibition of matrix molecule production, suggesting that this compound may promote OA cartilage repair by acting on subchondral bone osteoblasts. This finding constitutes a new mechanism of action for this compound, known for its beneficial effects on cartilage. [less ▲]

Liver transplantation is a major surgical procedure usually requiring large amount of blood products (red cells, platelets, fresh-frozen plasma). We developed a multidisciplinary transfusion-free protocol for liver transplantation in Jehovah's witnesses who refuse the use of blood products but accept organ transplantation. Between September 1998 and November 2004, 9 of 29 Jehovah's witnesses evaluated for liver transplantation were transplanted after medical preparation. None of these patients received any blood product during the surgical procedure. This experience may be beneficial for the entire liver transplantation population, as excessive transfusion has been linked to increased morbidity and mortality in liver transplantation. [less ▲]
