Effects of Glyburide-Cyclosporin A Interaction on Interleukin-2 Production in Rats1
The effects of simultaneous administrations of Cyclosporin A (CsA) and Glyburide on the immune system of rats has been evaluated in terms of Interleukin-2 (IL-2) production by Concanavalin A (ConA) stimulated splenocytes and exogenous IL-2 binding capacity. The inhibitory effect of Cyclosporin A on IL-2 production of lymphoid cells is well known. Spleen cells from rats receiving CsA had reduced levels of IL-2 when compared to untreated controls or rats receiving Glyburide only. Splenocytes from rats receiving both drugs had reduced levels of IL-2 when they were sacrificed 24 hours after one or three CsA administrations; instead when the animals were sacrificed 6 days after three CsA adminis…
Cyclosporine A + Glybenclamide. Effect on Glucose Metabolism: Preliminary Results
Cyclosporine A (CsA) is an immunosuppressive drug which determines, at high dosage, glucose intolerance (1). Different drugs present a pharmacological interaction with CsA increasing or reducing its blood level (2). To investigate the role of Glybenclamide (HB419), a sulphonilureic oral antidiabetic drug of large use, on CsA glucose metabolic effect, we have administered CsA + HB419 in rats. The aim of our work is to evaluate if HB419 influences CsA blood levels and if it improves glucose tolerance.
Lipoprotein a) levels in end-stage renal failure and renal transplantation
Some previous studies have documented an increase in lipoprotein (a) [Lp(a)] levels in renal diseases. Here, we report data in subjects with end-stage renal failure treated with hemodialysis (HD) or with continuous ambulatory peritoneal dialysis (CAPD) and in renal transplant recipients (RTR), compared with a group of normolipidemic controls (C). Lp(a) levels were significantly increased in HD and CAPD patients in comparison with C, while they were only slightly increased in RTR. Both HD and CAPD patients showed Lp(a) levels higher than in RTR, but no difference was found between the subjects of the two dialysis procedures. The prevalence of Lp(a) levels > 25 mg/dl was significantly higher …
