R73A and H144Q mutants of the yeast mitochondrial cyclophilin Cpr3 exhibit a low prolyl isomerase activity in both peptide and protein-folding assays. (1/2304)

Previously we reported that the R73A and H144Q variants of the yeast cyclophilin Cpr3 were virtually inactive in a protease-coupled peptide assay, but retained activity as catalysts of a proline-limited protein folding reaction [Scholz, C. et al. (1997) FEBS Lett. 414, 69-73]. A reinvestigation revealed that in fact these two mutations strongly decrease the prolyl isomerase activity of Cpr3 in both the peptide and the protein-folding assay. The high folding activities found previously originated from a contamination of the recombinant Cpr3 proteins with the Escherichia coli protein SlyD, a prolyl isomerase that co-purifies with His-tagged proteins. SlyD is inactive in the peptide assay, but highly active in the protein-folding assay.  (+info)

Tyrosine kinase inhibitors and immunosuppressants perturb the myo-inositol but not the betaine cotransporter in isotonic and hypertonic MDCK cells. (2/2304)

BACKGROUND: The sodium/myo-inositol cotransporter (SMIT) and the betaine cotransporter (BGT1) are essential for the accumulation of myo-inositol and betaine, and hence cell survival in a hypertonic environment. The underlying molecular mechanism involves an increase in transcription of the SMIT and BGT1 genes through binding of a trans-acting factor to enhancer elements in the 5' flanking region of both genes, resulting in increased mRNA abundance and increased activity of the cotransporters. Current evidence regarding transcriptional and post-transcriptional regulation indicates that both cotransporters are regulated in parallel. METHODS: To investigate the signal transduction of hypertonic stress, we examined the effect of tyrosine kinase inhibitors and immunosuppressants on the hypertonicity-induced activity of the two cotransporters in Madin-Darby canine kidney (MDCK) cells. RESULTS: None of the agents studied affected BGT1 activity in isotonic or hypertonic conditions. Treatment of MDCK cells with genistein, a tyrosine kinase inhibitor, increased SMIT activity in hypertonic but not isotonic conditions. The stimulation of SMIT by genistein was accompanied by a parallel increase in mRNA abundance. In contrast, treating cells with tyrphostin A23, another tyrosine kinase inhibitor, or cyclosporine A, an immunosuppressant, inhibited SMIT activity in hypertonic cells. FK506, another immunosuppressant, increased SMIT activity, but only in isotonic conditions. CONCLUSIONS: These results provide the first evidence of divergent regulatory pathways modulating SMIT and BGT activity.  (+info)

A prospective, randomized trial of tacrolimus/prednisone versus tacrolimus/prednisone/mycophenolate mofetil in renal transplant recipients. (3/2304)

BACKGROUND: Between September 20, 1995 and September 20, 1997, 208 adult patients undergoing renal transplantation were randomized to receive tacrolimus/prednisone (n=106) or tacrolimus/prednisone/mycophenolate mofetil (n=102), with the goal of reducing the incidence of rejection. METHODS: The mean recipient age was 50.7+/-13.7 years. Sixty-three (30.3%) patients were 60 years of age or older at the time of transplantation. The mean donor age was 34.5+/-21.7 years. The mean cold ischemia time was 30.5+/-9.2 hr. The mean follow-up is 15+/-7 months. RESULTS: The overall 1-year actuarial patient survival was 94%; the overall 1-year actuarial graft survival was 87%. When the patient and graft survival data were stratified to recipients under the age of 60 who did not have delayed graft function, the overall 1-year actuarial patient survival was 97%, and the corresponding 1-year actuarial graft survival was 93%. There were no differences between the two groups. The overall incidence of rejection was 36%; in the double-therapy group, it was 44%, whereas in the triple therapy group, it was 27% (P=0.014). The mean serum creatinine was 1.6+/-0.8 mg/dl. A total of 36% of the successfully transplanted patients were taken off prednisone; 32% of the patients were taken off antihypertensive medications. The incidence of delayed graft function was 21%, the incidence of cytomegalovirus was 12.5%, and the initial and final incidences of posttransplant insulin-dependent diabetes mellitus were 7.0% and 2.9%; again, there was no difference between the two groups. CONCLUSIONS: This trial suggests that the combination of tacrolimus, steroids, and mycophenolate mofetil is associated with excellent patient and graft survival and a lower incidence of rejection than the combination of tacrolimus and steroids.  (+info)

Hmo1p, a high mobility group 1/2 homolog, genetically and physically interacts with the yeast FKBP12 prolyl isomerase. (4/2304)

The immunosuppressive drugs FK506 and rapamycin bind to the cellular protein FKBP12, and the resulting FKBP12-drug complexes inhibit signal transduction. FKBP12 is a ubiquitous, highly conserved, abundant enzyme that catalyzes a rate-limiting step in protein folding: peptidyl-prolyl cis-trans isomerization. However, FKBP12 is dispensible for viability in both yeast and mice, and therefore does not play an essential role in protein folding. The functions of FKBP12 may involve interactions with a number of partner proteins, and a few proteins that interact with FKBP12 in the absence of FK506 or rapamycin have been identified, including the ryanodine receptor, aspartokinase, and the type II TGF-beta receptor; however, none of these are conserved from yeast to humans. To identify other targets and functions of FKBP12, we have screened for mutations that are synthetically lethal with an FKBP12 mutation in yeast. We find that mutations in HMO1, which encodes a high mobility group 1/2 homolog, are synthetically lethal with mutations in the yeast FPR1 gene encoding FKBP12. Deltahmo1 and Deltafpr1 mutants share two phenotypes: an increased rate of plasmid loss and slow growth. In addition, Hmo1p and FKBP12 physically interact in FKBP12 affinity chromatography experiments, and two-hybrid experiments suggest that FKBP12 regulates Hmo1p-Hmo1p or Hmo1p-DNA interactions. Because HMG1/2 proteins are conserved from yeast to humans, our findings suggest that FKBP12-HMG1/2 interactions could represent the first conserved function of FKBP12 other than mediating FK506 and rapamycin actions.  (+info)

Affinity modulation of small-molecule ligands by borrowing endogenous protein surfaces. (5/2304)

A general strategy is described for improving the binding properties of small-molecule ligands to protein targets. A bifunctional molecule is created by chemically linking a ligand of interest to another small molecule that binds tightly to a second protein. When the ligand of interest is presented to the target protein by the second protein, additional protein-protein interactions outside of the ligand-binding sites serve either to increase or decrease the affinity of the binding event. We have applied this approach to an intractable target, the SH2 domain, and demonstrate a 3-fold enhancement over the natural peptide. This approach provides a way to modulate the potency and specificity of biologically active compounds.  (+info)

Immunophilins, Refsum disease, and lupus nephritis: the peroxisomal enzyme phytanoyl-COA alpha-hydroxylase is a new FKBP-associated protein. (6/2304)

FKBP52 (FKBP59, FKBP4) is a "macro" immunophilin that, although sharing high structural and functional homologies in its amino-terminal domain with FKBP12 (FKBP1), does not have immunosuppressant activity when complexed with FK506, unlike FKBP12. To investigate the physiological function of FKBP52, we used the yeast two-hybrid system as an approach to find its potential protein partners and, from that, its cellular role. This methodology, which already has allowed us to find the FK506-binding protein (FKBP)-associated protein FAP48, also led to the detection of another FKBP-associated protein. Determination of the sequence of this protein permitted its identification as phytanoyl-CoA alpha-hydroxylase (PAHX), a peroxisomal enzyme that so far was unknown as an FKBP-associated protein. Inactivation of this enzyme is responsible for Refsum disease in humans. The protein also corresponds to the mouse protein LN1, which could be involved in the progress of lupus nephritis. We show here that PAHX has the physical capacity to interact with the FKBP12-like domain of FKBP52, but not with FKBP12, suggesting that it is a particular and specific target of FKBP52. Whereas the binding of calcineurin to FKBP12 is potentiated by FK506, the specific association of PAHX and FKBP52 is maintained in the presence of FK506. This observation suggests that PAHX is a serious candidate for studying the cellular signaling pathway(s) involving FKBP52 in the presence of immunosuppressant drugs.  (+info)

Synergic effects of tactolimus and azole antifungal agents against azole-resistant Candida albican strains. (7/2304)

We investigated the effects of combining tacrolimus and azole antifungal agents in azole-resistant strains of Candida albicans by comparing the accumulation of [3H]itraconazole. The CDR1-expressing resistant strain C26 accumulated less itraconazole than the CaMDR-expressing resistant strain C40 or the azole-sensitive strain B2630. A CDR1-expressing Saccharomyces cerevisiae mutant, DSY415, showed a marked reduction in the accumulation of both fluconazole and itraconazole. A CaMDR-expressing S. cerevisiae mutant, DSY416, also showed lower accumulation of fluconazole, but not of itraconazole. The addition of sodium azide, an electron-transport chain inhibitor, increased the intracellular accumulation of itraconazole only in the C26 strain, and not in the C40 or B2630 strains. Addition of tacrolimus, an inhibitor of multidrug resistance proteins, resulted in the highest increase in itraconazole accumulation in the C26 strain. The combination of itraconazole and tacrolimus was synergic in azole-resistant C. albicans strains. In the C26 strain, the MIC of itraconazole decreased from >8 to 0.5 mg/L when combined with tacrolimus. Our results showed that two multidrug resistance phenotypes (encoded by the CDR1 and CaMDR genes) in C. albicans have different substrate specificity for azole antifungal agents and that a combination of tacrolimus and azole antifungal agents is effective against azole-resistant strains of C. albicans.  (+info)

Primary adult liver transplantation under tacrolimus: more than 90 months actual follow-up survival and adverse events. (8/2304)

The introduction of tacrolimus has shown decreased rates of acute and steroid-resistant rejection after liver transplantation (LTx). The aim of the present study is to examine the long-term efficacy and safety of tacrolimus in primary liver transplant recipients. The first 121 consecutive adults (aged >16 years) who underwent primary LTx at a single center from August 1989 to February 1990 were followed up until August 1997. The mean follow-up was 93.2 +/- 1.2 months (range, 90.5 to 96.5 months). Patient survival, graft survival, rate of rejection, and adverse events were examined. The actual 7-year patient survival rate was 67.8%, and the graft survival rate was 63.6%. Infections, recurrence of disease, de novo malignancies, and cardiovascular events constituted the main causes of graft loss and death in the long term. Graft loss related to acute or chronic rejection was rare. The rate of acute rejection beyond 2 years was approximately 3% per year, and most rejections were steroid responsive. Approximately 70% of the patients received only tacrolimus after 1 year. Four patients developed end-stage renal disease, and 2 patients underwent kidney transplantation. Hyperkalemia and hypertension were observed in one third of the patients. New-onset insulin-dependent diabetes mellitus was observed in 9% and 13% of the patients at the 1-year and 7-year follow-up, respectively. Seven patients developed de novo malignancies, including two skin malignancies. Six patients developed posttransplantation lymphoproliferative disorder during the entire follow-up period. Actual patient and graft survival at 7 years was excellent, and few adverse events developed after the first year. Graft loss from acute or chronic rejection was rare under tacrolimus, and approximately 70% of the patients were steroid free on tacrolimus monotherapy after the first year after LTx.  (+info)

The pharmacogenetic evaluation of several genes implicated in drug pharmacokinetics should provide efficient tools for individualizing drug therapy by optimizing drug dosage. This would both improve drug efficacy and prevent adverse effects (19). Such evaluation may be particularly useful for drugs characterized by a narrow therapeutic index and/or significant toxicity, such as the calcineurin inhibitors tacrolimus and cyclosporine. In this study, we demonstrated that several polymorphisms of the MDR1 gene partly explain the variability of tacrolimus dose requirement in renal transplant recipients.. Abundantly expressed in the enterocytes, P-gp, the MDR1 gene product, may play an important role in the variability of tacrolimus absorption (7,20-23⇓⇓⇓⇓). Thus, interindividual variations in P-gp expression and/or function may explain the interindividual variability of tacrolimus bioavailability among individuals. Genetic polymorphisms related to the intestinal expression of P-gp therefore ...
We read with great interest the retrospective study by Di Maira et al1 which failed to establish an association between early exposure to calcineurin inhibitors (CNIs) and long-term outcomes among 432 patients who underwent liver transplantation (LT) in 2 centers. The authors suggested that early minimization of CNIs may have a limited prognostic impact.. Trough concentrations (TCs) of tacrolimus are set higher within the first month after LT, with a progressive reduction thereafter. In clinical practice, most patients converge at TC around 4-5 ng/mL from the sixth postoperative month onward. Therefore, the realistic window for a true minimization of tacrolimus is within the first months after LT. A systematic review and meta-analysis of 32 randomized trials comparing different targets of tacrolimus TC found a linear correlation between mean TC of tacrolimus within the first month and renal impairment rates at 1 year after LT.2 Indeed, patients receiving mean tacrolimus TC , 10 ng/mL showed ...

Tacrolimus (Prograf) belongs to a class of medications known as the calcineurin inhibitors. It is a maintenance drug that is used to prevent rejection in kidney, liver, and heart transplant recipients. Calcineurin inhibitors display high pharmacokinetic (the bodys effects on a drug) variability and necessitate use of blood tests to ensure that adequate drug levels are present to maintain effectiveness and safety. The amount of oral tacrolimus that is absorbed varies in all patient populations studied. Tacrolimus is metabolized or broken down for elimination by the liver and small intestine via cytochrome P450 (CYP)3A4, CYP 3A5, and p-glycoprotein enzyme systems. Enzyme activity is affected by several single nucleotide polymorphisms (SNPs) in an individuals genetic make-up and differences in expression may contribute to variations in tacrolimus pharmacokinetics. There are number of drug-drug interactions where concomitantly administered medications can increase or decrease this break down of ...
Purpose: Tacrolimus (TAC) immunosuppression requires therapeutic trough monitoring post-transplant due to notable interpatient pharmacokinetic(PK) variability which may be attributed to CYP3A5 polymorphisms. We investigated the relationship of therapeutic tacrolimus troughs to the corresponding drug exposure with CYP3A5 variants in stable renal transplant recipients(RTR) on long-term immunosuppression.. *Methods: The relationship between tacrolimus troughs(target: 4-12ng/ml) and Area Under the Concentration Time Curve 0-12 hours (AUC 0-12hr) with target exposure of 120 to 200 ng▪hr/ml, and CYP3A5 variants was investigated in 65 stable RTR treated with maintenance immunosuppression of immediate release tacrolimus and mycophenolic acid. A prospective study collected 12-hour serial samples for determination of steady-state tacrolimus PK including: AUC 0-12hr, 12hr troughs(C-12hr) and clearance(CL). The C-12hr were achieved using therapeutic drug monitoring. The CYP3A5 polymorphisms: ...
Audience: Pharmacists and organ transplantation healthcare professionals. [Posted 05/18/2006] Spectrum Laboratory Products and FDA notified healthcare professionals of the recall of the active pharmaceutical ingredient tacrolimus, an immunosuppressive drug used to prevent rejections of transplanted solid organs such as heart or kidney, after learning that some lots of the ingredient are subpotent. Spectrums tacrolimus API has been used by pharmacies for compounding purposes. The use of sub-potent tacrolimus in compounded drugs for transplant recipients may lead to sub-therapeutic tacrolimus blood levels and an unacceptable increased risk of solid organ transplant rejection. Patients receiving tacrolimus for solid organ transplant should not stop taking their medication, but rather should check with their physician or pharmacist. This recall does not apply to tacrolimus marketed in finished dosage form as Prograf (Astellas Pharma, US) or to Prograf oral capsules that have been used for ...

WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT. • Patients with low tacrolimus troughs are at a higher risk of rejection while those with high troughs are at an increased risk for toxicity. Therefore, achieving the therapeutic range is important.. • CYP3A5 genotype and days post transplant have been previously shown individually to be associated with tacrolimus troughs.. WHAT THIS STUDY ADDS. • This paper presents the first dosing model for tacrolimus using a combination of genetic and clinical factors in adult kidney transplant recipients. It was developed from one of the largest tacrolimus pharmacogenetic studies conducted to date (681 subjects and 11 823 trough concentrations).. • We found that CL/F was significantly influenced by days post transplant, CYP3A5 genotype, transplantation at a steroid sparing centre, recipient age and the use of a calcium channel blocker.. • Our large sample size enabled us to define the distinct differences in tacrolimus CL/F between three CYP3A5 genotype ...

The aim of the study was to estimate the use of tacrolimus C/D ratio for the assessment of the influence of gender differences and comedication on tacrolimus exposure in renal transplant recipients. The study was designed as a prospective case series study (54 patients), in which the unit of monitoring was outpatient examination (1872) of the renal transplant patients. The patients were monitored in the period 2010- 2014, starting one month after the transplantation. Tacrolimus trough concentrations (TTC) were measured by chemiluminescence microparticles immunoassay. TTC and tacrolimus C/D ratio were significantly lower in females comparing with males. Contrary to males, in females, a significant increase of tacrolimus daily dose (TDD) per body weight and TTC, along with the corticosteroid dose increase, was not accompanied by any significant changes in tacrolimus C/D ratio. In the patients treated with proton pump inhibitors, TDD per body weight and TTC were significantl...y higher, while ...
Tacrolimus is a macrolide antibiotic derived from the fungus Streptomyces tsukubaensis. Like cyclosporine, tacrolimus inhibits calcineurin to suppress T cells. Tacrolimus is metabolized by CYP3A4, thus its concentrations are affected by drugs that inhibit (calcium channel blockers, antifungal agents, some antibiotics, grapefruit juice) or induce (anticonvulsants, rifampin) this enzyme. Tacrolimus has a narrow therapeutic range, and adverse effects are common, particularly at high dose and concentrations, making therapeutic drug monitoring essential.. Since 90% of tacrolimus is in the cellular components of blood, especially erythrocytes, whole blood is the preferred specimen for analysis of trough concentrations. Target steady-state concentrations vary depending on clinical protocol, the presence or risk of rejection, time from transplant, type of allograft, concomitant immunosuppression, and side effects (mainly nephrotoxicity). Optimal trough blood concentrations are generally between 5.0 and ...

Eczrid Tacrolimus 0.03% Ointment is used to for treatment of atopic dermatitis, more commonly known as eczema - is a type of inflammation of the skin, dermatitis, a condition in which patches of skin become rough and inflamed with blisters which cause itching and bleeding. It results in itchy, red, swollen, and cracked skin. A clear fluid may come from the affected areas, which often thicken over time.. Tacrolimus (also FK-506 or fujimycin, trade names Prograf, Advagraf, Protopic) is an immunosuppressive medicine used main an after allogeneic organ transplant to lower the risk of organ rejection. It achieves this by inhibiting the production of interleukin-2, a molecule that promotes the development and proliferation of T cells, which are vital to the bodys learned (or adaptive) immune response. Tacrolimus is also used in the treatment of ...
Tacrolimus combined with mycophenolate mofetil (MMF) is an effective regimen in kidney transplantation. This study compared the efficacy of combining tacrolimus and two different dosages of sirolimus with an established tacrolimus-MMF regimen. Each day in addition to tacrolimus, 325 patients received 2 mg sirolimus (TAC-SRL2 mg), 325 patients received 0.5 mg sirolimus (TAC-SRL0.5 mg) and 327 patients 1 g MMF (TAC-MMF). The initial tacrolimus dose was 0.2 mg/kg/day. Sirolimus patients received loading doses of 6 or 1.5 mg, and daily doses of 2 or 0.5 mg thereafter. Steroid administration was identical for all groups. The incidence of biopsy-proven acute rejection was lower in the TAC-SRL2 mg group (15.7%) compared with the TAC-SRL0.5 mg (25.2%, p = 0.003) and the TAC-MMF groups (22.3%, p = 0.036). Six-month graft survival was 91.0% (TAC-SRL2 mg), 92.6% (TAC-SRL0.5 mg) and 92.4% (TAC-MMF); the respective values for patient survival were 98.1%, 97.8% and 97.9%. Thirty-four patients (10.5%), 19 ...

This study was undertaken to evaluate the efficacy of tacrolimus in treating steroid-resistant cellular myocardial rejection. Methods: We retrospectively analyzed the incidence of rejection and clinical outcome of 21 heart transplant recipients who were electively converted from cyclosporine to tacrolimus for recurrent episodes of steroid-resistant cellular rejection. These were compared to a historic group of 6 hemodynamically stable patients who were treated electively with Orthoclone OKT3 (Muromonab/CD3) for recurrent rejection. Results: Eighty five percent ...
Ventricular hypertrophy or hypertrophy of the septum, reported as cardiomyopathies have been observed in a few cases in association with administration of tacrolimus. Most of these have been reversible, occurring primarily in patients having tacrolimus blood trough levels higher than the recommended level. Mean tacrolimus whole blood trough concentrations during the period prior to diagnosis of myocardial hypertrophy in 20 patients with pre- and post-treatment echocardiograms ranged from 10.6 to 53.3 nanogram/mL in infants (N = 10, age 0.4 to 2 years), 4.0 to 45.7 nanogram/mL in children (N = 7, age 2 to 15 years) and 10.9 to 24.3 nanogram/mL in adults (N = 3, age 37 to 45 years). Other factors observed to increase the risk of these clinical conditions are, for example, previously existing heart diseases, corticosteroid usage, hypertension, renal or hepatic dysfunction, and fluid overload. Accordingly, high risk patients should be monitored, e.g. with echocardiography or ECG. If abnormalities ...

Critical organ shortage results in the utilization of extended donor criteria (EDC) liver grafts. These marginal liver grafts are prone to increased ischemia reperfusion injury (IRI) which may contribute to deteriorated graft function and survival. Experimental data have shown that the calcineurin inhibitor tacrolimus exerts protective effects on hepatic IRI when applied intravenously or directly as a hepatic rinse. Therefore, the aim of the present study is to examine the effects of an ex vivo tacrolimus perfusion on IRI in transplantation of EDC liver grafts. ...
This study is investigating early versus late conversion from Prograf (tacrolimus) to the Advagraf (tacrolimus) in liver transplant patients.
Arteriolar hyalinosis is a common histological finding in renal transplant recipients treated with the calcineurin inhibitor tacrolimus; however, the pathophysiologic mechanisms remain unknown. In addition to increasing transforming growth factor (TGF)-β levels, tacrolimus inhibits calcineurin by binding to FK506-binding protein 12 (FKBP12). FKBP12 alone also inhibits TGF-β receptor activation. Here we tested whether tacrolimus binding to FKBP12 removes an inhibition of the TGF-β receptor, allowing ligand binding, ultimately leading to receptor activation and arteriolar hyalinosis. We found that specific deletion of FKBP12 from endothelial cells was sufficient to activate endothelial TGF-β receptors and induce renal arteriolar hyalinosis in these knockout mice, similar to that induced by tacrolimus. Tacrolimus-treated and knockout mice exhibited significantly increased levels of aortic TGF-β receptor activation as evidenced by SMAD2/3 phosphorylation, along with increased collagen and ...
The immunosuppressant tacrolimus has a narrow therapeutic window, necessitating therapeutic drug monitoring to maintain efficacy and minimise toxicity. There are very few reports examining the impact of impaired biliary excretion on tacrolimus blood levels or toxicity. We report the case of a 26-year-old combined liver and kidney transplant recipient, who developed acute biliary obstruction leading to tacrolimus toxicity with very high blood tacrolimus levels. Despite a careful evaluation, no alternative cause was found for her acute kidney injury, and her kidney function returned to previous baseline within several days following treatment of the biliary obstruction and temporary withdrawal of tacrolimus ...
Pimecrolimus is an immunomodulating agent of the calcineurin inhibitor class used in the treatment of atopic dermatitis (eczema). It is available as a topical cream, once marketed by Novartis (however, Galderma has been promoting the compound in Canada since early 2007) under the trade name Elidel. Pimecrolimus is an ascomycin macrolactam derivative. It has been shown in vitro that pimecrolimus binds to macrophilin-12 (also referred to as FKBP-12) and inhibits calcineurin.[citation needed] Thus pimecrolimus inhibits T-cell activation by inhibiting the synthesis and release of cytokines from T-cells. Pimecrolimus also prevents the release of inflammatory cytokines and mediators from mast cells.[citation needed] Pimecrolimus, like tacrolimus, belongs to the ascomycin class of macrolactam immunosuppressives, acting by the inhibition of T-cell activation by the calcineurin pathway and inhibition of the release of numerous inflammatory cytokines, thereby preventing the cascade of immune and ...

TY - JOUR. T1 - Negative Cardiovascular Consequences of Small Molecule Immunosuppressants. AU - Chakkera, H. A.. AU - Sharif, A.. AU - Kaplan, B.. PY - 2017/8/1. Y1 - 2017/8/1. N2 - Immunosuppressants are critical after transplantation and prescribed as immune-modulators for autoimmune disorders and glomerulonephritides. Immunosuppressants include large (e.g., thymoglobulin, alemtuzumab, and rituximab) and small molecules (e.g., corticosteroids, calcineurin inhibitors, antimetabolites, and mammalian target of rapamycin (mTOR) inhibitors). The majority of the small molecules worsen traditional cardiovascular risks. This review describes cardiovascular risks of small molecule immunosuppressants: corticosteroids, calcineurin inhibitors (tacrolimus and cyclosporine), and mTOR inhibitors (rapamycin), by categorizing these risks into two categories: ischemic heart disease and nonischemic cardiac effects..

Tacrolimus (also FK-506 or fujimycin, trade names Prograf, Advagraf, Protopic) is an immunosuppressive drug used mainly after allogeneic organ transplant to lower the risk of organ rejection. It achieves this by inhibiting the production of interleukin-2, a molecule that promotes the development and proliferation of T cells, which are vital to the bodys learned (or adaptive) immune response. Tacrolimus is also used in the treatment of other T cell-mediated diseases such as eczema (for which it is applied to the skin in a medicated ointment), severe refractory uveitis after bone marrow transplants, exacerbations of minimal change disease, Kimuras disease, and the skin condition vitiligo. Chemically it is a 23-membered macrolide lactone that was first discovered in 1987 from the fermentation broth of a Japanese soil sample that contained the bacterium Streptomyces tsukubaensis. It has similar immunosuppressive properties to ciclosporin, but is much more potent. Immunosuppression with tacrolimus ...
The immunogen for 14H04 was tacrolimus linked to KLH via C22, and the immunogen for 1E2 was linked to KLH via C32. There was a separation of 10 carbon atoms between the 2 linkages. Since the antibody-binding region is usually away from the drug-KLH linkage, we surmised that this spatial separation might result in 2 non- or minimally overlapping epitopes. We further hypothesized that the spatially separated epitopes might result in simultaneous binding of the 2 antibodies to the tacrolimus molecule.. On the basis of this hypothesis and available cross-reactivity data, we performed an analysis to locate epitopes for the antibodies to rule out overlaps between their binding sites. To deduce the binding sites for an antibody in the absence of the x-ray cocrystal structure of antibody-drug complexes, we examined the change in binding affinity by altering chemical groups on tacrolimus. If an alteration substantially lowered or eliminated antibody binding, it was reasonable to assume that this chemical ...
We present a case which reports the occurrence of a potential elevation of Tacrolimus (Tac) plasma levels to toxic values in a renal transplant recipient after adding Metronidazole (Met) to the medication regimen. A 30-year old female, status post living-related renal transplant, who was stabilized on Tac 4.5 mg, twice daily, for 4 months, presented to the clinic with diarrhea. We used Microparticle Enzyme Immunoassay (MEIA) to determine Tac trough concentration (trough concentrations 5-10 ng/ml). After 6 days of Met therapy on 1.5 g/d, Tac trough concentration and serum creatinine (sCr) increased to 20.2 ng/ml and 7.8 mg/dl respectively. Met therapy was discontinued, also one dose of Tac was withheld, while daily dose was decreased to 2 mg/d. Four days after Met discontinuation, Tac concentration dropped to 8.7 ng/ml, sCr to 2.1 mg/dl, warranting Tac dose increase to 3 mg/d. Co-administration of Tac with Met may result in elevated Tac concentrations, possibly leading to tacrolimus ...

ISD assays are used to determine the drug concentration in the patients blood as a guide for effective and well-tolerated doses as the desired therapeutic effect is only obtained in a narrow therapeutic range: The dose must be high enough to prevent organ rejection, and the dose must be low enough to avoid drug toxicity and opportunistic infections ...
Tacrolimus is an immunosuppressant drug used to prevent organ rejection in patients who have undergone kidney, heart or liver transplantation. It is also applied externally for skin conditions such as eczema particularly atopic dermatitis. Tacrolimus is very effective than cyclosporine.
In detail, tacrolimus reduces peptidylprolyl isomerase activity by binding to the immunophilin FKBP12 prograf , creating a new advanced. This FKBP12-FK506 complicated interacts with and inhibits calcineurin, thus inhibiting both T-lymphocyte sign transduction and IL-2 transcription. Within the previous 12 months, you may have heard about two new medications that had been approved by the FDA for use in kidney prograf transplant recipients, Nulojix® injection and Astagraf XL® (extended-release tacrolimus) capsules. Both of those medications have been accredited to be used along with steroids and mycophenolate to stop transplant rejection. The recommended initial dose of Prograf injection is 0.03-zero.05 mg/kg/day in kidney and liver transplant and zero.01 mg/kg/day in coronary heart transplant given as a continuous infusion into a vein .

We present a case of tacrolimus-induced acute pancreatitis with positive rechallenge. The 24-year-old male patient underwent kidney transplant and received immunosuppressive therapy with tacrolimus. On day 10 post-transplant, he presented with abdominal pain. A laboratory analysis showed elevated serum amylase and serum lipase levels. An abdominal computed tomography scan showed large-volume ascites and pelvic cavity effusion. These findings led to a diagnosis of acute pancreatitis. After tacrolimus was temporarily stopped and altered with cyclosporine, his symptoms decreased and he was restarted with tacrolimus. On day 61, laboratory tests again revealed significant elevations of serum amylase and serum lipase. A computed tomography scan of the abdomen showed increased pancreatic tail fluid collections. We excluded other possible causes and concluded that tacrolimus was the definite inducer of pancreatitis. The patient was switched from tacrolimus to cyclosporine again. Serum amylase and serum ...
Background: Topical calcineurin inhibitors including tacrolimus and pimecrolimus are used in the treatment of many inflammatory skin diseases mainly via blocking T-cell proliferation. Our previous studies found that pimecrolimus 1% cream could reverse high-dose ultraviolet B (UVB) irradiation-induced epidermal Langerhans cell (LC) reduction via inhibition of LC migration. We conducted this study to investigate the effects of topical tacrolimus 0.03% ointment on high-dose UVB-irradiated human epidermal LCs.Methods: Twenty fresh human foreskin tissues were randomly divided into four groups as follows: Control, Tacrolimus (0.03%), UVB (180 mJ/cm2), and UVB (180 mJ/cm2) + Tacrolimus (0.03%). Four time points were set as follows: 0, 18, 24, and 48 h. We collected culture medium and tissues at each time point. The percentage of CD1a+ cells in the medium was detected by means of flow cytometry. Each tissue was prepared for immunohistochemistry, real-time quantitative PCR, and western blot. HaCaT cells were
An adequate level of tacrolimus in serum should be obtained to prevent acute rejection following liver transplantation. Because of good gastrointestinal absorption of oral tacrolimus, adequate trough levels can be achieved even in patients with short bowel syndrome. Rarely, adequate through levels cannot be obtained by oral administration of the drug for several reasons such as inadequate absorption, having a discordant patient, laboratory error, and/or interactions with other drugs and foods. Here, we described a 16-year-old patient who had undergone massive intestinal resection due to mesenteric torsion 5 years previously and required liver transplantation for cryptogenic cirrhosis. Her remnant small bowel length was 90 cm. After a successful living donor liver transplantation, oral tacrolimus administration resulted in inadequate through levels in some parts of the postoperative period. We checked up all the potential reasons but could not identify any cause. An intravenous tacrolimus ...

Pimecrolimus cream, 1% is not indicated for use in children less than 2 years of age. The long-term safety and effects of pimecrolimus cream, 1% on the developing immune system are unknown.. Three Phase 3 pediatric trials were conducted involving 1,114 subjects 2 to 17 years of age. Two trials were 6-week randomized vehicle-controlled trials with a 20-week open-label phase and one was a vehicle-controlled (up to 1 year) safety trial with the option for sequential topical corticosteroid use. Of these subjects 542 (49%) were 2 to 6 years of age. In the short-term trials, 11% of pimecrolimus subjects did not complete these trials and 1.5% of pimecrolimus subjects discontinued due to adverse events. In the one-year trial, 32% of pimecrolimus subjects did not complete this trial and 3% of pimecrolimus subjects discontinued due to adverse events.

section 4.5 Tacrolimus There is a risk of increased tacrolimus blood levels when co-administered with amlodipine but the pharmacokinetic mechanism of this interaction is not fully understood. In order to avoid toxicity of tacrolimus, administration of amlodipine in a patient treated with tacrolimus requires monitoring of tacrolimus blood levels and dose adjustment of tacrolimus when appropriate.. Ciclosporin No drug interaction studies have been conducted with ciclosporin and amlodipine in healthy volunteers or other populations with the exception of renal transplant patients, where variable. trough concentration increases (average 0% - 40%) of ciclosporin were observed.. Consideration should be given for monitoring ciclosporin levels in renal transplant patients on amlodipine, and ciclosporin dose reductions should be made as necessary. ...
BACKGROUND: Local drug delivery systems that adjust the release of immunosuppressive drug in response to the nature and intensity of inflammation represent a promising approach to reduce systemic immunosuppression and its side effects in allotransplantation. Here we aimed to demonstrate that release of tacrolimus from triglycerol monostearate hydrogel is inflammation-dependent in vivo. We further report that by loading the hydrogel with a near-infrared dye, it is possible to monitor drug release non-invasively in an in vivo model of vascularized composite allotransplantation.. MATERIALS AND METHODS: Inflammation was induced by local challenge with lipopolysaccharides in naïve rats 7 days after injection of tacrolimus-loaded hydrogel in the hind limb. Tacrolimus levels in blood and tissues were measured at selected time points. A near-infrared dye was encapsulated in the hydrogel together with tacrolimus in order to monitor hydrogel deposits and drug release in vitro and in vivo in a model of ...
Pediatric patients with systemic‑onset juvenile idiopathic arthritis (SOJIA) may be treated with tacrolimus. However, the therapeutic range for tacrolimus is narrow with considerable inter‑ and intra‑individual variability, making it difficult to formulate an ideal dosage regimen for personalized treatment. The purpose of the present study was to set up a population pharmacokinetics (PPK) model of tacrolimus treatment for SOJIA to determine the optimal initial dosage. Patients with SOJIA were analyzed using non‑linear mixed‑effects modeling. Different regimens were analyzed using Monte Carlo simulation with concentration profiles. A first‑order absorption and elimination one‑compartment model was selected as the most appropriate model for SOJIA. Based on initial dosage recommendations, the regimen of 0.5 mg every 24 h (q24h) appeared to be most suitable for subjects with a body weight of 5 kg, while the 0.5 mg q12h regimen was most suitable for subjects with a body weight of ...
The above information should be taken into account when considering conversion from calcineurin inhibitors to Rapamune in stable renal transplant patients due to the lack of evidence showing that renal function improves following conversion, and the finding of a greater increment in urinary protein excretion, and an increased incidence of treatment-emergent nephrotic range proteinuria following conversion to Rapamune. This was particularly true among patients with existing abnormal urinary protein excretion prior to conversion.. In an open-label, randomized, comparative, multicenter study where kidney transplant patients were either converted from tacrolimus to sirolimus 3 to 5 months post-transplant (sirolimus group) or remained on tacrolimus, there was no significant difference in renal function at 2 years post-transplant. Overall, 44/131 (33.6%) discontinued treatment in the sirolimus group versus 12/123 (9.8%) in the tacrolimus group. More patients reported adverse events 130/131 (99.2%) ...
Maintenance immunosuppression with sirolimus (SRL) in renal transplantation has been associated with proteinuria. We report long-term outcomes of kidney transplant recipients maintained on steroid-free regimens, either SRL with low-dose tacrolimus (SRL/L-Tac) or mycophenolate mofetil (MMF) with high-dose tacrolimus (MMF/H-Tac). We conducted a case-matched study of 50 patients receiving MMF/H-Tac, matched 1:2 with 100 patients maintained on SRL/L-Tac. All patients were induced with rabbit antithymocyte globulin followed by early steroid withdrawal. Comparisons were made of patient and graft survival, graft function, acute rejection, and albuminuria. There were no significant differences between the SRL/L-Tac and MMF/H-Tac groups for patient survival, graft survival, occurrence of acute rejection, or graft function. There was no difference in the proportion of patients with albumin/creatinine ratio (ACR) ≥300 μg/mg (19% vs. 20%), but more patients in the SRL group were receiving renin-angiotensin
Annular erythema is an unusual, often idiopathic disorder that tends to respond poorly to topical therapy. Two patients with idiopathic, topical corticosteroid-resistant annular erythema showed prompt clearing of lesions treated with 0.1% tacrolimus ointment and persistence of untreated ones which themselves responded to subsequent treatment. These two cases demonstrate a clear-cut therapeutic response of chronic, topical corticosteroid-resistant annular erythema to topical tacrolimus ointment 0.1% BID. Additional experience with tacrolimus ointment, hopefully in controlled circumstances, should clarify its potential value in treating annular erythema.
Background: The DIAMOND study of de novo liver transplant patients showed that prolonged-release tacrolimus exposure in the acute post-transplant period maintained renal function over 24 weeks of treatment. To assess these findings further, we performed a post-hoc analysis in patients according to baseline kidney function, Model for End-stage Liver Disease [MELD] scores, and donor age. Material/Methods: Patients received prolonged-release tacrolimus (initial-dose, Arm 1: 0.2 mg/kg/day, Arm 2: 0.15-0.175 mg/kg/day, Arm 3: 0.2 mg/kg/day delayed until Day 5), mycophenolate mofetil and 1 steroid bolus. Arms 2 and 3 also received basiliximab. The recommended tacrolimus target trough levels to Day 42 post-transplantation were 5-15 ng/mL in all arms. In this post-hoc analysis, change in renal outcome, based on estimated glomerular filtration rate (eGFR), Modified Diet in Renal Disease-4 (MDRD4), values from baseline to Week 24 -post-transplantation, were assessed according to baseline patient factors: ...

Purpose: The interaction between tacrolimus (FK) and posaconazole (POSA) is well documented, however the extent of this interaction and the practical management has yet to be fully described post-liver transplant. Literature evaluating this interaction has been hindered by small sample sizes, limited patient populations, use of various POSA formulations and little evidence describing the timing of the interaction. Recent construction at this institution prompted the use of POSA due to its coverage of mold species. The goal of this study is to quantify the interaction between FK and delayed release POSA tablets.. *Methods: This was a single-center, retrospective study that included adult liver transplant recipients between 8/1/17 - 9/1/20. The primary endpoint was the difference in the day 5 FK C/D in the POSA group compared to a control. Secondary endpoints included the incidence of acute kidney injury (AKI), biopsy proven acute rejection (BPAR) within one month of azole discontinuation, length ...

Prograf can cause neurotoxicity and nephrotoxicity, particularly when used in high doses. Nephrotoxicity was reported in approximately 52% of kidney transplantation patients and in 40% and 36% of liver transplantation patients receiving Prograf in the U.S. and European randomized trials, respectively, and in 59% of heart transplantation patients in a European randomized trial (see ADVERSE REACTIONS). Use of Prograf with sirolimus in heart transplantation patients in a US study was associated with increased risk of renal function impairment, and is not recommended (See CLINICAL STUDIES). More overt nephrotoxicity is seen early after transplantation, characterized by increasing serum creatinine and a decrease in urine output. Patients with impaired renal function should be monitored closely as the dosage of Prograf may need to be reduced. In patients with persistent elevations of serum creatinine who are unresponsive to dosage adjustments, consideration should be given to changing to another ...

Topical immunomodulators, such as tacrolimus and pimecrolimus, have been the most promising recent additions to topical vitiligo therapy. In fact because of their efficacy and a remarkable safety profile the use of these agents in vitiligo has shown a consistently increasing trend over the last few years. These agents can be safely administered in young children, as they dont cause any atrophy or telangiectasia of the skin even after prolonged use. There is also no risk of hypothalamic-pituitary-adrenal (HPA) axis suppression as seen with the widespread use of potent topical steroids.33 The first study that demonstrated the efficacy of tacrolimus in vitiligo was published in 2002.34 In this study tacrolimus was used in six patients with generalized vitiligo and five of them achieved ,50% repigmentation of their lesions by the end of study period.34 Since then many additional studies have been published on this subject and have clearly demonstrated the role of topical tacrolimus in vitiligo. The ...
BACKGROUND: In vivo studies have highlighted allogeneic mesenchymal stem-cell (MSC) immunogenicity. We investigated in vitro MSC-immunosuppressive drugs interaction and further tested in vivo the humoral response to intracardiac allogeneic MSC transplantation in a mini-swine model receiving a short course of immunosuppression. METHODS: For in vitro experiments, long-term culture MSCs were used. Immunosuppressive drugs tested were mycophenolate mofetil, cyclosporin, tacrolimus (TAC), sirolimus (SIR), and everolimus. Cell proliferation/viability was assessed on day 7. For each drug, the C50 was determined, and the agonistic effect between immunosuppressive drugs and MSCs on alloreactivity was measured in proliferation assay of MSC-peripheral blood mononuclear cell cultures. For in vivo experiments, one-haplotype swine leukocyte antigen class I and II mismatch (n=11) were used. Allogeneic MSCs were transplanted into ischemic myocardium. TAC was administered 12 days. Donor-specific antibody response ...

Tacrolimus is a macrolide antibiotic derived from the fungus Streptomyces tsukubaensis. Like ciclosporin, tacrolimus inhibits calcineurin to suppress T cells. Tacrolimus is metabolised by CYP3A4, thus its concentrations are affected by drugs that inhibit (calcium channel blockers, antifungal agents, some antibiotics, grapefruit juice) or induce (anticonvulsants, rifampin) this enzyme. Tacrolimus has a narrow therapeutic range, and adverse effects are common, particularly at high dose and concentrations, making therapeutic drug monitoring essential.. ...

Introduction: Antiproliferative effects of immunosuppressants used in human islet transplantation interfere with the capability of the beta cells to balance cell renewal and cell loss. Consequently, long-term use of these drugs might contribute to graft dysfunction in islet transplant recipients. New immunosuppressive regimens are required to improve outcomes.. Materials and methods: Syngeneic islets (300 IEQ) were injected into the right liver lobes of C57BL/6 diabetic mice. Osmotic pumps filled with Bromodeoxyuridine (group 1), Bromodeoxyuridine and Tacrolimus (group 2) or Bromodeoxyuridine and Everolimus (group 3) were implanted. Hepatectomy was performed after 4 weeks. Proliferation of beta cells was detected by BrdU incorporation. Results: In all transplanted animals normoglycemia was restored. Glucose tolerance was significantly improved after 4 weeks in group 1 (90min: P, 0.012; 120min: P,0.045). This effect was not as strong when animals were treated with Tacrolimus. In contrast, mice ...
Active-targeted delivery to lymph nodes represents a major advance toward more effective treatment of immune-mediated disease. The MECA79 antibody recognizes peripheral node addressin molecules expressed by high endothelial venules of lymph nodes. By mimicking lymphocyte trafficking to the lymph nodes, we have engineered MECA79-coated microparticles containing an immunosuppressive medication, tacrolimus. Following intravenous administration, MECA79-bearing particles showed marked accumulation in the draining lymph nodes of transplanted animals. Using an allograft heart transplant model, we show that targeted lymph node delivery of microparticles containing tacrolimus can prolong heart allograft survival with negligible changes in tacrolimus serum level. Using MECA79 conjugation, we have demonstrated targeted delivery of tacrolimus to the lymph nodes following systemic administration, with the capacity for immune modulation in vivo.. ...
