Objectives—An analysis of the eYcacy of tacrolimus treatment in three patients with diYcult and severe systemic lupus erythematosus (SLE) whose active disease had been previously poorly controlled by cyclosporine and cyclophosphamide. Methods—A review of patient notes. Results—Two patients are well controlled after six and nine months of treatment with tacrolimus 0.06 mg/kg/day and 0.18 mg/kg/d...

The purpose of this paper was to determine the efficacy and safety of topical tacrolimus, compared to cyclosporine, for treating keratoconjunctivitis sicca (KCS) in dogs. This study was a two-phase, randomized, controlled, masked clinical trial. Phase 1 evaluated ophthalmic 0.03% tacrolimus in normal dogs. Ocular examinations were performed daily. Phase 2 evaluated the efficacy of tacrolimus in...

We present a 56-year-old male kidney transplant recipient who was hospitalized for acute kidney injury due to gastroenteritis related volume depletion and had kindey function deterioration secondary to rising plasma levels of tacrolimus after metronidazole administration. Tacrolimus dose was decreased and arranged daily by closely drug level monitoring. His creatinine value returned to his basa...

Lipopolysaccharide (LPS)‑induced keratitis is a progressive infectious ocular disease in which innate inflammatory responses often cause clinical tissue damage and vision loss. The present study aimed to investigate the effects of tacrolimus, an effective immunomodulator, on LPS‑induced innate immune responses. The effects of tacrolimus on the apoptotic rate and viability of human corneal epith...

BACKGROUND Permeability glycoprotein (P-glycoprotein or P-gp) plays an important role in the intestinal absorption of the immunosuppressive agents: cyclosporine and tacrolimus. OBJECTIVES The aim of this study was to determine how the intestinal absorption of cyclosporine and tacrolimus is affected when they are used with P-gp activating or inhibiting agents. MATERIAL AND METHODS In in vitr...

It has been difficult to set an individualized therapeutic window of tacrolimus after organ transplantation, because of wide interindividual variation of responsiveness to immunosuppressive therapy. In this study, we examined the significance of multidrug resistance 1 (MDR1) in the peripheral blood cells by comparing the trough concentration of tacrolimus with the occurrence of acute cellular r...

Tacrolimus and rapamycin both belong to a new family of immunosuppressants, immunophilin ligands, but the mechanisms by which they inhibit T cell activation are different. Therefore, we tested the immunosuppressive effects of combination therapy with low doses of tacrolimus and rapamycin on experimental autoimmune uveoretinitis (EAU) in rats. Male Lewis rats, immunized with S-antigen (S-Ag) wer...

OBJECTIVE To compare tacrolimus with cyclosporin for immunosuppression in renal transplantation. DESIGN Meta-analysis of randomised trials of two treatments after kidney transplantation. IDENTIFICATION Four studies involving 1037 patients. Trials were included if they were randomised, the intervention group received tacrolimus, the control group received cyclosporin, the patients were follo...

PURPOSE To report the clinical outcome of the treatment of dry eyes using 0.03% tacrolimus eye drops (olive oil + tacrolimus 0.03%) (Ophthalmos, Sao Paulo, Brazil). METHODS Sixteen eyes of 8 patients with Sjögren syndrome dry eyes (age, 51.13 ± 9.45 years) were enrolled in this study (prospective noncontrolled interventional case series). Patients were instructed to use topical 0.03% tacrolim...

Calcineurin inhibitor induced thrombotic microangiopathy is a rare but well recognized complication of a renal transplantation that occurs in 1% of the patients who are on tacrolimus immunosuppression. Among the other aetiological factors of the "de-novo" Thrombotic Microangiopathy (TMA), the condition especially has to be differentiated from an antibody mediated rejection, as both have differe...
