Recent studies have shown that cyclosporin A (CsA) may affect ricin A-chain immunotoxin (RTA-IT) therapy. In this study, we evaluated the ability of CsA and its nonirnmunosuppressive analog. SDZ PSC 833, to enhance anti-CD5 T l O l RTA-ITS in vitro. Both 4 pmol/L CsA and 4 pmol/L SDZ PSC 833 significantly and specifically enhanced the cytotoxic activity of T101 RTA-IT on the human lymphoblastic...

AIM To determine the effects of a three month course of low dose cyclosporin on the expression of epidermal cell adhesion molecules. METHODS Eighteen patients with psoriasis were treated for 12 weeks with either 2.5 or 5 mg/kg/day of oral cyclosporin. Biopsy specimens taken from skin before, during, and after cyclosporin treatment were stained immunohistochemically for CD 54 (ICAM-1), CD 29 (...

This study tests the hypothesis that the clinical response to cyclosporin therapy of patients with chronic severe asthma is related to the sensitivity of their T-lymphocytes to the antiproliferative effects of cyclosporin in vitro. In a previous study, we observed such a relationship with glucocorticoids and the same lectin-driven proliferation assay was used in the present study. Peripheral bl...

In patients receiving cyclosporin to minimise graft versus host disease after allogeneic bone marrow transplantation, whole blood cyclosporin concentration was roughly twice the serum concentration when blood was separated at 37 degrees C. In turn, blood separation at 37 degrees C resulted in a doubling of serum cyclosporin concentration compared with separation at room temperature. In vitro st...

OBJECTIVE We present a prospective study of a microemulsion of cyclosporin to treat idiopathic nephrotic syndrome in ten children with normal renal function who presented cyclosporin trough levels between 50 and 150 ng/ml and achieved complete remission with cyclosporin. To compare the pharmacokinetic parameters of cyclosporin in idiopathic nephrotic syndrome during remission and relapse of the...

Cyclosporin therapy is associated with several forms of nephrotoxicity, the most significant of which are reversible impairment of glomerular filtration and irreversible interstitial fibrosis. Impaired glomerular filtration is due to both reduction in Kf, the glomerular capillary ultrafiltration coefficient, and to reduction in renal blood flow. The mechanisms responsible for the low Kf are not...

allogeneic hematopoietic stem cell transplantation (hsct) is a curative treatment option for hematological disorders. cyclosporine (csa) is one of the major immunosuppressive agents for the prophylaxis against graft versus host disease (gvhd). in this retrospective study, we evaluated the effects of csa serum levels on the incidence of acute gvhd and transplant outcomes. 103 adult patients rece...

Since arthritis induced by Mycobacterium products (adjuvant) in rats is considered to be immunologically driven, the objective of the present study was to determine if the immunosuppressor drug cyclosporin could affect hindpaw edema and joint hyperalgesia simultaneously. Female Holtzman rats (140-170 g) presented hyperalgesia and edema on the 8th and 12th day following adjuvant injection. Daily...

Cyclosporin toxicity may produce a wide range of neurological disorders. We report three patients whose neurological problems developed while taking cyclosporin following cardiac transplantation, but resolved rapidly when the drug was discontinued. In two cases, MRI revealed abnormalities which disappeared with clinical recovery. Blood cyclosporin concentrations were not markedly increased, and...
