The dose-response and plasma concentration-response relationships of cyclosporine after both inducing and inhibiting its metabolism were studied in a mouse heart transplant model. The metabolism of cyclosporine was altered by coadministering phenobarbital and cimetidine as metabolism inducing and inhibiting agents, respectively. We found that phenobarbital depressed the immunosuppressive potenc...
PURPOSE OF REVIEW The purpose of the review is to review the pathophysiology, available data, and our current recommendations for calcineurin inhibitor (cyclosporine and tacrolimus) treatment in antihistamine refractory chronic idiopathic urticaria (CIU) patients. RECENT FINDINGS Low-dose cyclosporine (<5 mg/kg per day) may have unique immunological modulating properties beyond mast cell and...
BACKGROUND The aetiology of central nervous system lesions observed in cerebral cyclosporine neurotoxicity remains controversial. CASE PRESENTATION We report a 48-year-old woman with a non-severe aplastic anaemia who presented with stroke-like episodes while on cyclosporine treatment.Transcranial Doppler ultrasound revealed severely elevated flow velocities in several cerebral vessels, consis...
Background & Aims: The immunosuppressive drug cyclosporine with a narrow therapeutic range and variable pharmacokinetic characteristics among individuals is a substrate for cytochrome P450 (CYP) 3A and P-glycoprotein, the product of the multidrug resistance 1 (MDR1) gene. Some of the single nucleotide polymorphisms (SNPs) in these genes are associated with deficient protein expression and red...

BACKGROUND Cyclosporine increases thromboxane synthesis in dogs, potentially increasing the thrombogenic properties of platelets. HYPOTHESIS/OBJECTIVES Our hypothesis was that the concurrent administration of low-dose aspirin and cyclosporine would inhibit cyclosporine-associated thromboxane synthesis without altering the antiplatelet effects of aspirin. The objective was to determine the eff...
We show that monitoring of cyclosporine by immunoassay could be improved by using monoclonal antibodies (MAbs) of restricted specificity instead of polyclonal antisera that recognize both unmodified cyclosporine and its metabolites. MAbs with high affinity for cyclosporine have been prepared and characterized. We tested their ability to discriminate between native cyclosporine and its metabolit...
Cyclosporine is an immunosuppressive substance that causes structural and functional alterations in endothelial cells. To examine the effects of chronic cyclosporine therapy on endothelial function, Wistar Kyoto rats received daily s.c. injections of saline, cyclosporine solvent, or cyclosporine (15, 30, or 50 mg/kg) for up to 2 wk. Blood pressure remained unchanged in all groups. Segments of t...
BACKGROUND With advances in antiretroviral therapy, many human immunodeficiency virus (HIV)-infected individuals are living longer and developing end-stage renal or hepatic disease requiring transplantation. Maintaining the viability of the transplant and suppressing HIV replication requires concomitant use of immunosuppressants (e.g., cyclosporine) and antiretrovirals (e.g., protease inhibitor...
Background/aim This study explored the mechanisms of allogeneic graft versus leukemia effect in acute lymphoblastic (ALL) cells by examining whether they change gene expression post-transplant environment containing cytokines and immunosuppressant cyclosporine, if such changes affect ALL cell survival. Materials methods RNASeq was used to assess global flow cytometry measure survival presence T...
