Correlation Between Tacrolimus Levels in Blood Samples Obtained from Central Catheter and Peripheral Venipuncture in Lung Transplant Patients (Ven-Cat Study).

Background: Following lung transplantation (LT), receiving immunosuppressive therapy is crucial. Tacrolimus is considered a drug with a narrow therapeutic range and its use requires constant monitoring. This study aimed to evaluate the correlation between tacrolimus levels obtained from central venous catheter and direct venipuncture in adult patients undergoing LT.

Off-Label Immunosuppressant Drugs in Solid Organ Transplantation.

Once a solid organ transplantation (SOT) has been performed, it is necessary to prescribe immunosuppressant medication to prevent graft rejection. This task has the peculiarity that many of these drugs do not have specific indications for transplant use in the technical data sheets. We performed a review of different immunosuppressive drugs' information available at European and American regulatory agencies in order to analyze the approved indications by the type of SOT.

Donor-Derived Cell-Free DNA at 1 Month after Kidney Transplantation Relates to HLA Class II Eplet Mismatch Load.

Kidney transplantation is the preferred therapeutic option for end-stage renal disease; however, the alloimmune response is still the leading cause of renal allograft failure. To better identify immunologic disparities in order to evaluate HLA compatibility between the donor and the recipient, the concept of eplet load has arisen. Regular kidney function monitoring is essential for the accurate and timely diagnosis of allograft rejection and the appropriate treatment.

Torque Teno Virus Load Predicts Opportunistic Infections after Kidney Transplantation but Is Not Associated with Maintenance Immunosuppression Exposure.

Measuring the non-pathogenic Torque Teno Virus (TTV) load allows assessing the net immunosuppressive state after kidney transplantation (KTx). Currently, it is not known how exposure to maintenance immunosuppression affects TTV load. We hypothesized that TTV load is associated with the exposure to mycophenolic acid (MPA) and tacrolimus.

Calcineurin inhibitors' impact on cardiovascular and renal function, a descriptive study in lung transplant recipients from the North of Spain.

Patients undergoing lung transplantation (LTx) need administration of immunosuppressive therapy following the procedure to prevent graft rejection. However, these drugs are not exempt from potential risks. The development of cardiovascular risk factors and impaired renal function in the post-transplantation period are conditions that may be favoured by the use of calcineurin inhibitor (CNI) drugs which could have repercussions on the quality of life and the post-transplantation evolution.

Lower Time in Therapeutic Range Relates to a Worse Kidney Graft Outcome.

Tacrolimus has a narrow therapeutic margin. Maintaining tacrolimus blood levels in the appropriate range is difficult because of its intrapatient variability. In fact, greater blood level variability has been related to worse kidney graft outcome, but only measuring variability does not consider the therapeutic range goal.

Efficacy and safety of endoscopic sleeve gastroplasty versus laparoscopic sleeve gastrectomy in obese subjects with Non-Alcoholic SteatoHepatitis (NASH): study protocol for a randomized controlled trial (TESLA-NASH study).

Background: Non-alcoholic steatohepatitis (NASH) is frequently associated with obesity, and its standard treatment is weight loss with diet and exercise; a dy% weight reduction has been associated with improvement in liver histological and analytical abnormalities. However, less than 25% of subjects achieve this goal. Laparoscopic sleeve gastrectomy (LSG) represents the most common procedure of bariatric surgery, providing effective weight loss and improvement in comorbidities such as NASH, but it is associated with several postoperative complications.

Controlled, double-blind, randomized trial to assess the efficacy and safety of hydroxychloroquine chemoprophylaxis in SARS CoV2 infection in healthcare personnel in the hospital setting: A structured summary of a study protocol for a randomised controlled trial.

Background: SARS-CoV-2 infection presents a high transmission in the group of health professionals in Spain (12-15% infected). Currently there is no accepted chemoprophylaxis but hydroxychloroquine (HDQ) is known to inhibit the coronavirus in vitro. Our hypothesis is that oral administration of hydroxychloroquine to healthcare professionals can reduce the incidence and prevalence of infection as well as its severity in this group.

[Usefulness of the summary of product characteristics as a tool to improve prescription in elderly patients].

Background And Objective: The Drug Technical Data Sheet should contribute to a safe and effective use of medications in the elderly, providing accurate information on the prescription, on the possible benefits or risks of the medications, or failing that, communicating the lack of information on their use in this group. The aim of this article was to quantify the specific information for people over 65 years of age included in the data sheets of the drugs available in Spain, and enables an adequate prescription in this population.

Materials And Methods: A multidisciplinary group reviewed all the Technical Data Sheets of drugs approved by the Spanish Agency for Medicines and Health Devices (AEMPS).

Spanish list of potentially inappropriate drugs in the elderly (ES-PIA project).

Purpose: In the last decades, different criteria have been developed for detecting inappropriate prescription in older patients. In Spain, translations and adaptations of international lists are available but it would be necessary a national list which could cope with the peculiarities of our health system, existing pharmaceutical market, and prescription habits. We propose in this project the creation of a Spanish potentially inappropriate drugs list which could be applicable in our clinical scenario.

Metformin-associated hyperlactacidaemia acidosis: Diagnosis rate in standard clinical practice and its relationship with renal failure.

Background And Objectives: Observational study on the difference between the number of cases of acidosis with hyperlactacidaemia suspected of being caused by metformin diagnosed in standard clinical practice and the incidence of this condition according to the datasheet. The study also explored the relationship between renal function and metformin-associated hyperlactacidaemia acidosis.

Patients: We identified cases of acidosis between 2013 and 2014 by analysing the minimum basic data set and laboratory requests.

Study Design and Rationale of "A Multicenter, Open-Labeled, Randomized Controlled Trial Comparing MIdazolam Versus MOrphine in Acute Pulmonary Edema": MIMO Trial.

Purpose: Morphine has been used for several decades in cases of acute pulmonary edema (APE) due to the anxiolytic and vasodilatory properties of the drug. The non-specific depression of the central nervous system is probably the most significant factor for the changes in hemodynamics in APE. Retrospective studies have shown both negative and neutral effects in patients with APE and therefore some authors have suggested benzodiazepines as an alternative treatment.

Influence of genetic polymorphisms of CYP3A5 and ABCB1 on sirolimus pharmacokinetics, patient and graft survival and other clinical outcomes in renal transplant.

Background: In transplant patients receiving de novo anticalcineurin-free sirolimus (SRL)-based immunosuppression, we determined the influence of cytochrome P450 3A5 (CYP3A5) and ATP-binding cassette, sub-family B (MDR/TAP), member (ABCB1) genotypes on SRL blood levels and medium-term relevant clinical outcomes, in order to improve effectiveness of immunosuppression strategies when anti-mammalian target of rapamycin (anti-mTOR) inhibitor is indicated for clinical reasons.

Methods: Forty-eight renal transplant recipients (suffered 48% diabetes mellitus, 91% hypertension, and 47% dyslipidemia) were genotyped for CYP3A5 (6986A>G) and ABCB1 (3435C>T) polymorphisms by polymerase chain reaction-restriction fragment length polymorphism. Sirolimus blood levels were determined using microparticle enzyme immunoassay technique.

Effect of intravenous and intracoronary melatonin as an adjunct to primary percutaneous coronary intervention for acute ST-elevation myocardial infarction: Results of the Melatonin Adjunct in the acute myocaRdial Infarction treated with Angioplasty trial.

The MARIA randomized trial evaluated the efficacy and safety of melatonin for the reduction of reperfusion injury in patients undergoing revascularization for ST-elevation myocardial infarction (STEMI). This was a prespecified interim analysis. A total of 146 patients presenting with STEMI within 6 hours of chest pain onset were randomized to receive intravenous and intracoronary melatonin (n=73) or placebo (n=73) during primary percutaneous coronary intervention (PPCI).

Psychiatric Disorders and Montelukast in Children: A Disproportionality Analysis of the VigiBase(®).

Introduction: In 2008, the US FDA issued an alert about an increased risk of psychiatric events associated with montelukast. Recent national pharmacovigilance analyses in Sweden, France and Spain detected a potential increase in reporting risk of the association.

Aim: Our objective was to analyse spontaneous reports of psychiatric events in children and adolescents worldwide treated with montelukast.

[Emergent drugs (II): the Pharming phenomenon].

The use of medicines, with or without medical prescription, for recreational ends by the young population has received little attention from doctors. In the USA, one in five adolescents has used medicines for recreational purposes, and consultations in Emergency Departments for medicine abuse have exceeded those for illegal drugs. Although few data are available in Spain, such consumption is situated between 3.

Paediatric adverse drug reactions reported to the Spanish Pharmacovigilance System from 2004 to 2009.

Purpose: This study was conducted to evaluate relevant new information about ADRs reported in the Spanish paediatric population over a 6-year period.

Methods: Adverse drug reactions (ADRs) for individuals aged 0-17 years reported to the Spanish Pharmacovigilance System from 2004 to 2009 were analysed with respect to time, age and sex, category of ADR [System Organ Class (SOC)], seriousness, suspected medicines [level 2 of the Anatomical Therapeutic Chemical (ATC) Classification System] and type of reporter.

Results: In total, 4,279 ADR reports corresponding to 8,196 ADRs were analysed, approximately two ADRs per report.

Pharmacokinetics of once- versus twice-daily tacrolimus formulations in kidney transplant patients receiving expanded criteria deceased donor organs: a single-center, randomized study.

Background: Noncompliance to immunosuppressive treatment is 1 of the risk factors for kidney graft loss. The once-daily, prolonged-release tacrolimus formulation may improve treatment adherence. We sought to compare the pharmacokinetics of both tacrolimus formulations in older de novo recipients of a cadaveric renal transplant from an expanded-criteria donor.

Net efficacy adjusted for risk (NEAR): a simple procedure for measuring risk:benefit balance.

Background: Although several mathematical models have been proposed to assess the risk:benefit of drugs in one measure, their use in practice has been rather limited. Our objective was to design a simple, easily applicable model. In this respect, measuring the proportion of patients who respond favorably to treatment without being affected by adverse drug reactions (ADR) could be a suitable endpoint.

Factors influencing cyclosporine blood concentration-dose ratio.

Objective: To analyze the trough cyclosporine concentration-dose ratio (CDR) and its relationship to some commonly available factors such as cyclosporine dosage, patient age, grade of obesity, posttransplant days, serum creatinine, serum bilirubin, and serum cholesterol by multiple linear regression.

Methods: The study was performed on 866 samples from 90 transplant recipients (25 kidney, 25 heart, 17 bone marrow, 13 liver, 10 simultaneous pancreas-kidney).

Results: The results show differences between transplants both in cyclosporine CDR variability (expressed by the coefficients of variation) and in the capability of those factors to explain this variability (expressed by the coefficient of determination).
