Exploring the impact of pharmacogenetics on personalized medicine: A systematic review.

INTRODUCTION: Pharmacogenetics evaluates how genetic variations influence drug responses. Nowadays, genetic tests have advanced, becoming more affordable, and its integration is supported by stronger clinical evidence. Guidelines such as those from CPIC (Clinical Pharmacogenetics Implementation Consortium) and resources like PharmGKB facilitate genotype-based prescribing; and organizations like the FDA promote genetic testing before initiating certain medications. Preventive pharmacogenetic panels seem promising, but further research on biomarkers and diverse populations is needed. The aim of this review is to analyze recent evidence on the genotype-drug response relationship to examine how the genetic profile of patients influences the clinical response to treatments, and analyze the areas of research that need further study to advance towards a genetic-based precision medicine. MATERIALS AND METHODS: A systematic search was conducted on PubMed to identify articles investigating the genotype-drug response relationship. The search strategy included terms such as "pharmacogenetics", "personalized treatment", "precision medicine", "dose adjustment", "individualizing dosing", "clinical routine", and "clinical practice." Clinical trials, observational studies, and meta-analyses published in English or Spanish between 2013 and 2023 were included. The initial search resulted in a total of 136 articles for analysis. RESULTS: 49 articles were included for the final analysis following review by 2 investigators. A relationship between genetic polymorphisms and drug response or toxicity was found for drugs such as opioids, GLP-1 agonists, tacrolimus, oral anticoagulants, antineoplastics, atypical antipsychotics, efavirenz, clopidogrel, lamotrigine, anti-TNFα agents, voriconazole, antidepressants, or statins. However, for drugs like metformin, quetiapine, irinotecan, bisoprolol, and anti-VEGF agents, no statistically significant association between genotype and response was found. CONCLUSION: The studies analyzed in this review suggest a strong correlation between genetic variability and individual drug responses, supporting the use of pharmacogenetics for treatment optimization. However, for certain drugs like metformin or quetiapine, the influence of genotype on their response remains unclear. More studies with larger sample sizes, greater ethnic diversity, and consideration of non-genetic factors are needed. The lack of standardization in analysis methods and accessibility to genetic testing are significant challenges in this field. As a conclusion, pharmacogenetics shows immense potential in personalized medicine, but further research is required.

Factors Contributing to Negative Outcomes Associated with Medications and Drug-Related Problems in Kidney Replacement Therapy-A Hospital-Based Prospective Observational Study.

BACKGROUND: Negative outcomes associated with medications (NOM) and drug-related problems (DRP) significantly impact individuals with kidney replacement therapy (KRT) given the complexities of managing kidney disease and associated comorbidities. The present study aims to assess the frequency of NOMs/DRPs among KRT patients and identify contributing factors. METHODS: A cross-sectional study was conducted at Virgen de las Nieves University Hospital (Granada, Spain), involving 117 outpatient adults with KRT. Data were collected from February 2021 to July 2023 using electronic records, semi-structured interviews (Dáder Method), and discussions with nephrology specialists. NOMs/DRPs were identified following treatment guidelines. Binary logistic regression was used to determine associated factors (p-value < 0.05). RESULTS: Across 117 patients, 2436 NOMs and 3303 DRPs were identified, averaging 20.82 NOMs and 28.23 DRPs per patient. Prevalent NOMs included untreated conditions (58.95%), quantitative ineffectiveness (35.43%), and non-quantitative safety problems (5.13%). Dominant DRPs were undertreated conditions (37.63%), wrong dose/posology/length (33.00%), risk of adverse drug reactions (ADR) (16.14%), and non-adherence (6.87%). Patients with ADR, undertreated conditions, and anemia were associated with quantitative ineffectiveness. Risk of ADR and vitamin D deficiency/insufficiency correlated with non-quantitative safety problems. CONCLUSIONS: KRT patients exhibited a substantial prevalence of NOMs/DRPs. Further research is needed to deepen our understanding of these complexities for improved patient care.

[Translated article] Checklist for the pharmaceutical care of patients with interstitial lung disease (CheckEPID): A Delphi-based consensus.

OBJECTIVE: To develop a checklist to facilitate pharmaceutical care for patients with interstitial lung disease who require or are undergoing treatment with antifibrotic drugs. METHOD: Five hospital pharmacists developed an initial list of 37 items divided into 4 blocks: (1) First visit, which included general patient data and data from the first treatment; (2) follow-up visits, assessing aspects of the follow-up of the treatment with nintedanib or pirfenidone; (3) telepharmacy, consisting of the evaluation of the inclusion of patients in a program of this type, course of the disease, and identification of the contact with the pharmacy service; (4) non-pharmacological treatment and patient information. To decide its potential inclusion in the checklist, 2 rounds of the Delphi were carried out in which the panelists had to assess the degree of agreement of each proposed item according to its "utility", which was the determining criterion for its inclusion, and its "applicability". RESULTS: Forty-eight hospital pharmacists were contacted, 30 (63%) agreed in writing to participate, 28 (58%) completed the first round of the Delphi, and 27 (56%) completed the second round. After the first round of the Delphi, the questionnaire was amended and comprised 40 items. Of the 40 items evaluated after the 2 rounds of the Delphi, there were 2 that, based on utility, the participants did not reach consensus for inclusion in the checklist: the one referring to "History of surgical intervention, specifically abdominal surgery in the last 4 weeks" (finally kept on the checklist due to its involvement in the indication of nintedanib) and to make recommendations on "Relaxation". No consensus was reached on their applicability for 2 of the items: "Patient stratification according to the Spanish Society of Hospital Pharmacy (SEFH) chronic patient model" and "Collection of Results Reported by the Patient". CONCLUSIONS: The management of patients with ILD and/or pulmonary fibrosis is complex and requires a multidisciplinary approach where the hospital pharmacist plays a key role, especially, although not only, in monitoring drug treatment. We believe that this checklist can contribute from pharmaceutical care to improving the integrated care of patients with ILD who require or are undergoing treatment with antifibrotic drugs.

Medication Review with Follow-Up for End-Stage Renal Disease: Drug-Related Problems and Negative Outcomes Associated with Medication-A Systematic Review.

BACKGROUND: This article reviews the available scientific literature on drug-related problems and negative outcomes associated with medications identified by medication review with follow-up for end-stage renal disease and discussed with the physicians. METHODS: A systematic review was conducted of the scientific literature retrieved from the following databases: MEDLINE (via PubMed), Web of Science, SCOPUS, Cochrane Library: The Cochrane Central Register and Control Trials (CENTRAL) and Literatura Latinoamericana y del Caribe (LILACS), Medicina en Español (MEDES), and the SciELO bibliographic database (a collection of scientific journals). The following terms were used as descriptors and searched in free text: "end-stage renal disease", "medication review", "drug-related problems", and "negative outcomes associated with medication". The following limits were applied: "humans" and "adults (more than 18 years)". RESULTS: A total of 59 references were recovered and, after applying inclusion/exclusion criteria, 16 articles were selected. Of these selected articles, 15 provided information on drug-related problems and only 1 on negative outcomes associated with medications. CONCLUSIONS: It can be concluded that drug-related problems and negative outcomes associated with medications affect patients with end-stage renal disease, mainly those receiving renal replacement therapy. More evidence is needed, especially on negative outcomes associated with medication.

Clinical Outcomes of First-line Therapies for Advanced Non-Small Cell Lung Cancer: A Systematic Review of Trials Published Between 2010 and 2020.

OBJECTIVES: To analyze the evolution of clinical outcomes derived from clinical trials on first-line therapies for advanced or metastatic non-small cell lung cancer (NSCLC) published between 2010 and 2020, focusing on how these outcomes impact survival rates and management of patients. METHODS: A systematic review of phase III and pivotal phase II clinical trials was conducted by a structured search on Medline and Embase. A comprehensive set of variables was collected to assess their influence on survival rates. We also estimated the clinical benefit by applying the ESMO-MCBS v1.1 and extracted the authors' conclusions. RESULTS: Sixty-six studies involving 34,951 patients were included. Best survival outcomes were found for nonsquamous non-small cell lung cancer (OS and progression-free survival medians: 19.4 and 10.2 mo) and for those expressing molecular targets (OS and progression-free survival medians: 23.8 and 11.0 mo). No significant influence on survival rates was observed for industry funding and disease stage (IIIB/IV vs. IV). ESMO-MCBS v1.1 was applied in 45 positive studies and resulted in a meaningful clinical benefit score in 37.8%. Quality of life (QoL) was reported in 57.6% of the original publications and showed statistical significance favoring the experimental arm in 33.3%. Positive authors' conclusions (75.7% of trials) were based on OS and/or QoL in 34% and on surrogate endpoints in 66%. CONCLUSIONS: Extended survival times and a steady improvement in QoL have been observed. However, there were more than twice as many studies reporting positive authors' conclusions as studies meeting the ESMO threshold for meaningful clinical benefit.

Contribution of cabotegravir + rilpivirine long-acting for the treatment of HIV-1 infection.

OBJECTIVE: To determine the value contribution of cabotegravir + rilpivirine, the first injectable every two months long-acting antiretroviral  regimen, using multi-criteria decision analysis. METHOD: The study was developed in two phases. After a small pilot, a field  ork study with a larger number of multidisciplinary experts was carried out.  Seven single-tablet regimens, currently recommended by the GeSIDA  guidelines, were selected as comparators. EVIDEM methodology was followed,  with a framework composed by 12 quantitative and 5 contextual criteria. Mean  and standard deviations were calculated for quantitative criteria (1 to 5 scale;  comparative criteria -5 to +5), whereas qualitative criteria were analyzed as  percentages of experts that considered a positive, neutral or negative impact  for the National Health System. RESULTS: 35 experts participated in the study. Human immunodeficiency virus- 1 infection was considered severe (mean ± standard deviation: 3.0 ± 1.0),  with moderate size of affected population (2.7 ± 1.2) and unmet needs (2.8 ±  1.0). Minimal differences were found in comparative efficacy/effectiveness (0.1  ± 0.5), safety/tolerability (-0.5 ± 0.7), and cost criteria: cost of the  intervention (0.5 ± 2.0), other medical costs (0.2 ± 1.8) and non- medical/indirect costs (0.5 ± 1.6). Experts perceived an improvement with  cabotegravir + rilpivirine long-acting, compared  to current daily oral single-tablet regimens, in patient-reported outcomes (2.7 ± 1.4). Therapeutic benefit  of the long-acting regimen was considered moderate-to-high (3.5 ± 1.2).  Experts considered the evidence provided by cabotegravir + rilpivirine long- actingrobust (4.3 ± 0.8), with elevated consensus on its future  recommendation in guidelines (3.2 ± 1.0). In contextual criteria, most experts  considered positive the impact on population priorities and access (91%),  common goal and specific interests (63%) and political, historical, and cultural  context criteria (60%). Impact was neutral in system capacity and appropriate  use (40%), and opportunity costs and affordability criteria (51%). Result of the  weighted global value contribution of cabotegravir + rilpivirine long-acting  was 0.34 (-1 to +1 scale), with Patient Reported Outcomes comparative  criterion bringing the highest added value. CONCLUSIONS: Cabotegravir + rilpivirine long-acting provides added value  contribution to human immunodeficiency virus-1 management in Spain  compared to daily oral single-tablet regimens. Patient Reported Outcomes and  therapeutic benefit of cabotegravir + rilpivirine long-acting were highly valued  by experts, as the expected benefit in adherence and stigma-related issues  would improve overall quality of life for people living with human  immunodeficiency virus-1.

A strategic reflection for the management and implementation of CAR-T therapy in Spain: an expert consensus paper

CAR-T cell therapy represents a therapeutic revolution in the prognosis and treatment of patients with certain types of hematological cancer. However, they also pose new challenges in the healthcare, regulatory and financial fields. The aim of the RET-A project was to undertake a strategic reflection on the management of CAR-T therapies within the Spanish National Health System, to agree on recommendations that will help to better deal with the new context introduced by these cell therapies in the present and in the future. This think tank involved 40 key agents and opinion leaders. The experts identified three great challenges for implementing advanced therapies in Spain: therapeutic individualisation, with a multidisciplinary approach; acceleration of access times, by minimizing bureaucracy; and increase in the number of centers qualified to manage the CAR-T therapies in the NHS. The experts agreed on the ideal criteria for designating those qualified centers. They also agreed on a comprehensive CAR-T care pathway with the timings and roles which would ideally be involved in each part of the process.

Effectiveness and safety of topical 15% resorcinol in the management of mild-to-moderate hidradenitis suppurativa: A cohort study.

Antibiotics remain one of the main treatment alternatives in mild-to-moderate hidradenitis suppurativa. The use of topical 15% resorcinol reduces antibiotic pressure and the generation of resistance. However, knowledge on its efficacy and safety is limited. This single-center, prospective, follow-up cohort study evaluated topical 15% resorcinol every 12-h response at 16 weeks. Those individuals with mild-to-moderate hidradenitis suppurativa (Hurley I-II) who started treatment with topical resorcinol monotherapy between April 2019 and May 2020 were eligible for follow-up. The primary endpoint for effectiveness was the proportion of patients who achieved an overall clinical response (complete or partial response) at week 16, evaluated as intention-to-treat. Responses were measured according to the Hidradenitis Suppurativa Clinical Response index. Target lesion size was measured clinically and by ultrasonography. Quality of life was assessed through the Dermatology Life Quality Index (DLQI) questionnaire. Safety was measured by recording the adverse events reported during the follow-up period. A total of 32 patients were enrolled (mean age, 40.1 years [95% confidence interval, 35.7-44.4]; women, 20 [62.5%]; Hurley I, 17 [53.1%]). Under the intention-to-treat analysis, 68.8% (n = 22) of the patients achieved a clinical response. A ≥50% reduction in the size of the main lesion was observed in 56.3% of the patients (n = 18). Some 65.6% (n = 21) of the patients had a ≥50% reduction (improvement) in their baseline DLQI score. Fifty percent of patients who completed the follow-up period experienced adverse events, all of which were local, mild, and transient and did not lead to discontinuation of resorcinol. To conclude, in this cohort study, topical 15% resorcinol was shown to be effective for mild-to-moderate hidradenitis suppurativa and to have a positive impact on quality of life with an acceptable safety profile.

Adverse events reported after administration of BNT162b2 and mRNA-1273 COVID-19 vaccines among hospital workers: a cross-sectional survey-based study in a Spanish hospital.

BACKGROUND: The World Health Organization declared COVID-19 a pandemic in March 2020. The first vaccine became available in December, with practically no post-marketing data. METHODS: An analytical cross-sectional survey-based study was conducted in a third-level hospital in Spain between March and April 2021 to describe the difference in adverse events with the BNT162b2 and mRNA-1273 COVID-19 vaccines. The participants were hospital workers who completed a survey voluntarily at least 14 days after the last vaccine. The STROBE checklist was followed. RESULTS: One thousand two hundred and forty-nine respondents completed the survey; 48% (599) received mRNA-1273 and 52% (650) BNT162b2. Fourteen thousand four hundred and two adverse reactions were recorded, 6896 local (3939 with mRNA-1273 and 2957 with BNT162b2 (6.6 vs 4.4 reactions per patient)) and 7506 systemic (4460 with mRNA-1273 and 3046 with BNT162b2 (7.4 vs 4.7 per patient)). Local reactions were more frequent after the first dose, while systemic reactions were higher after the second, for both vaccines and in a higher percentage with mRNA-1273 compared to BNT162b2 (p-value<0.05). CONCLUSIONS: Licensed mRNA vaccines were highly safe when administered under post-marketing conditions among working-age adults. The main adverse events were mild, although they occurred in most patients, especially after the mRNA-1273 vaccine.

Discontinuation of cholinesterase inhibitor treatment in institutionalised patients with advanced dementia.

OBJECTIVE: To evaluate the impact of discontinuation of treatment with cholinesterase inhibitors (ChEIs) on cognitive, behavioural and functional outcomes in patients with severe dementia. METHODS: A prospective observational study in which the prescribing physician decides, depending on multidisciplinary assessment and following the recommendations of the clinical practice guidelines, whether to withdraw or continue ChEI treatment in institutionalised patients, with a follow-up of 3 months. Cognitive abilities were measured using the Mini-Mental State Examination (MMSE) and Reisberg's Global Deterioration Scale (GDS). Other measures were the behavioural and psychological symptoms of dementia (BPSD) according to the Neuropsychiatric Inventory (NPI), the activities of daily living using the Barthel index, the pharmacological and the non-pharmacological measures to treat the BPSD. RESULTS: ChEI treatment was discontinued in 23 of 43 patients. After 3 months there were no differences in MMSE (p=0.441), GDS (p=0.976), NPI (p=0.882) or Barthel index (p=0.080) scores, or the establishing of new pharmacological measures (p=0.919) or non-pharmacological measures (p=0.832). CONCLUSIONS: ChEI discontinuation in advanced stage dementia was not related to clinical deterioration in terms of cognitive function, BPSD, or functional status. Discontinuing ChEI treatment according to a multidisciplinary assessment and the recommendation of the guidelines appears to be a possible way of optimising pharmacotherapy without altering the main clinical evaluation scales.

Formulation, long-term physicochemical and microbiological stability of 15% topical resorcinol for hidradenitis suppurativa.

OBJECTIVES: Topical resorcinol 15% is a self-treatment for painful hidradenitis suppurativa nodules and abscesses with good results in reducing pain and lesion duration. The aim of this study is to establish a 15% topical resorcinol formula, to develop a physicochemical and microbiological stability study and to further determine the compounding shelf-life in different package conditions following the European Pharmacopoeia (Ph. Eur.) specifications. METHODS: Physicochemical and microbiological stability studies of the formulation were conducted for 12 months at room temperature (25°C±2°C) in different package conditions: aluminium tubes (aluminium A7-99.7% varnish DF-6172), plastic tubes (low density polyethylene) and amber plastic containers (polyethylene terephthalate). High performance liquid chromatography (HPLC) was developed as a method of indicating the stability of the resorcinol formulation. A microbiological growth assay was also validated according to the Ph. Eur. Physical properties were inspected to determine parameters such as odour, colour, pH, emulsion phase and extensibility index and its evolution. RESULTS: The HPLC method was validated according to the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) guidelines. At day 365, visual inspection remained unchanged only for preparations packaged in aluminium tubes. The pH did not vary by more than 0.3 units in all conditions. The extensibility index decreased in the preparations packaged in plastic and amber plastic containers. HPLC analysis conducted over 1 year did not show a degradation greater than 7% of resorcinol in the preparation in plastic and aluminium packages. The ability of ATCC strains to grow in resorcinol formulation was confirmed under the suitability test. Resorcinol packed in aluminium tubes achieved microbiological stability at day 365. CONCLUSIONS: Only the formulation package in aluminium tubes showed physicochemical and microbiological stability of resorcinol for 12 months at room temperature (25°C±2°C).

Switch to subcutaneous infliximab during the SARS-CoV-2 pandemic: preliminary results.

A new subcutaneous formulation of the infliximab biosimilar CT-P13 has recently been developed for the treatment of inflammatory bowel disease (IBD), providing response rates similar to intravenous treatment. The use of this new formulation was requested, in an effort to limit patient attendance at intravenous infusion centers and to maintain biological treatment during the COVID-19 pandemic. The objective of this observational, retrospective and descriptive study was to assess CT-P13 efficacy and safety after switching from intravenous to a subcutaneous formulation in patients with IBD receiving maintenance therapy. This article shows preliminary results after six months of follow-up.

Genetic polymorphisms on the effectiveness or safety of breast cancer treatment: Clinical relevance and future perspectives.

Breast cancer (BC) is the most frequent neoplasm and one of the main causes of death in women. The pharmacological treatment of BC consists of hormonal therapy, chemotherapeutic agents and targeted therapy. The response to BC therapy is highly variable in clinical practice. This variability can be explained by the presence of genetic polymorphisms in genes involved in the pharmacokinetics, pharmacodynamics or immune response of patients. The abundant evidence of associations between low-activity alleles CYP2D6*3, *4, *5, *6, *10 and *41 and poor results with tamoxifen therapy, and between DPYD gene polymorphisms rs3918290, rs55886062, rs67376798 and rs75017182 and increased risk of toxicity to fluoropyrimidine therapy, justify the existence of clinical pharmacogenetic guidelines. The NQO1 rs1800566 polymorphism is related to poorer results in BC therapy with chemotherapy agents. The polymorphism rs1695 of the GSTP1 gene has been associated with the effectiveness and toxicity of fluorouracil, cyclophosphamide and epirubicin therapy. Finally, the HLA-DQA1*02:01 allele is significantly associated with the occurrence of liver toxicity events in patients receiving lapatinib. There is moderate evidence to support the aforementioned associations and, therefore, a high probability of these being considered as future predictive genetic biomarkers of response. However, further studies are required to reinforce or clarify their clinical relevance.
