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. In our work, besides showing these differences between different indication approvals in different SOT modalities, we also attempted to reflect other differences under the approved indications according to age group, formulation type, geographical area, etc. Although consensus documents on the subject have been published, the access to immunosuppressants depends on each country's regulation and healthcare system, and off-label prescription is a reality that healthcare professionals need to be familiar with.

Pharmacogenomics in clinical trials: an overview.

With the trend towards promoting personalised medicine (PM), the application of pharmacogenetics and pharmacogenomics (PGx) is of growing importance. For the purposes of clinical trials, the inclusion of PGx is an additional tool that should be considered for improving our knowledge about the effectiveness and safety of new drugs. A search of available clinical trials containing pharmacogenetic and PGx information was conducted on ClinicalTrials.gov. The results show there has been an increase in the number of trials containing PGx information since the 2000 s, with particular relevance in the areas of Oncology (28.43%) and Mental Health (10.66%). Most of the clinical trials focus on treatment as their primary purpose. In those clinical trials entries where the specific genes considered for study are detailed, the most frequently explored genes are CYP2D6 (especially in Mental Health and Pain), CYP2C9 (in Hematology), CYP2C19 (in Cardiology and Mental Health) and ABCB1 and CYP3A5 (particularly prominent in Transplantation and Cardiology), among others. Researchers and clinicans should be trained in pharmacogenetics and PGx in order to be able to make a proper interpretation of this data, contributing to better prescribing decisions and an improvement in patients' care, which would lead to the performance of PM.

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. To evaluate the cardiovascular and renal toxicity following the administration of CNI as maintenance immunosuppression in lung transplant recipients (LTRs) we reviewed a total number of 165 patients undergoing LTx between 01/01/2015 and 08/12/2018. They were divided into two groups according to the CNI drug administrated: cyclosporine (CsA-group) with 11 patients or tacrolimus (Tac-group), with 154 patients. We evaluated the de novo occurrence of arterial hypertension (HTN), diabetes mellitus (DM), hyperlipidemia and impaired renal function after initiation of CNI administration. In addition to that, the time until each of these events was assessed. A higher rate for developing HTN (p < 0.001) and impaired renal function (p = 0.047) was observed within the CsA-group. The new onset of hyperlipidemia was similar between both CNI groups and de novo appearance of DM was only documented in those LTRs receiving tacrolimus. In this LTRs retrospective study, it was observed that having ≥ 4 tacrolimus trough levels above the upper limit of the proposed interval for each specific post-LTx period was associated with an increased risk for developing renal impairment. No other statistically significant association was found between supratherapeutic CNIs blood levels and the evaluated toxicities.

European association for clinical pharmacology and therapeutics young clinical pharmacologists working group: a cornerstone for the brighter future of clinical pharmacology.

The European Association for Clinical Pharmacology and Therapeutics (EACPT) is a leading society in Europe serving the European and global Clinical Pharmacology and Therapeutics community. Its specific aims include promotion of the utilisation and divulgation of the utility of clinical pharmacology services in health care delivery. EACPT currently has four active working groups (WGs): Education, Regulatory affairs, Clinical research and Young Clinical Pharmacologists (YCP WG). EACPT YCP WG was established in 2015 with the idea of improving education, research, training and networking/mobility opportunities for YCPs across Europe and globe. The main objective of the present manuscript is to provide detailed information on general characteristics, structure, chronogram, objectives, accomplishments and current/future focus areas of the EACPT YCP WG. Consequently, we tend to notably enhance EACPT YCP WG's visibility, increase the number of its members and mobility/networking options and to expand areas of activity even more. Moreover, by this we can also make clinical pharmacology more attractive to early career fellows and colleagues and empower its position alongside other medical specialties.

Toxicidad grave por metotrexato en el anciano: nuestra experiencia en los últimos 7 años / Severe methotrexate toxicity in elderly: 7 years experience

El metotrexato es uno de los fármacos más empleados en pacientes con procesos reumatológicos, debido a su eficacia y perfil de seguridad. Sin embargo, los pacientes tratados con este fármaco son en ocasiones de edad avanzada, por lo que el riesgo de toxicidad aumenta, así como el de intoxicación por error en la toma de la medicación. Presentamos el caso de una paciente de 87 años, polimedicada, con antecedentes de deterioro cognitivo y escaso apoyo social que sufrió una intoxicación aguda grave por metotrexato. Además, describimos las características de los casos de toxicidad por este fármaco ingresados en nuestro Hospital en los últimos 7 años

Methotrexate is one of the most widely used drugs in rheumatology due to its high efficacy-to-toxicity. However, patients treated with this drug are sometimes elderly, which increases toxicity risks, as well as mistakes in taking the medication. The case is presented of an 87 year-old patient, on multiple medications, with a history of cognitive impairment and low social support, who suffered acute methotrexate toxicity. A description is also presented on the characteristics of the toxicity cases due this drug admitted to this hospital in the last 7 years
