RESUMO
INTRODUCTION: Abiraterone and enzalutamide are two androgen receptor pathway inhibitors approved, among others, for the treatment of metastatic castration-resistant prostate cancer in adult men whose disease has progressed on or after a docetaxel-based regimen. Although hematological effects, especially neutropenia, are one of the main complications of other oral antineoplastic drugs, these adverse effects are infrequent in the case of androgen receptor pathway inhibitors. CASE REPORT: We report the case of a patient diagnosed with metastatic castration-resistant prostate cancer who discontinued an androgen receptor pathway inhibitor due to drug-related grade 4 neutropenia. His control blood counts before enzalutamide starting were normal. After one month of treatment, he developed a grade 4 neutropenia, with complete neutrophil count recovery four weeks later. He underwent a bone marrow aspiration, which revealed normocelullar results, and enzalutamide was restarted. Three weeks later, the treatment was eventually discontinued due to neutropenia reappearance. Neutrophil count recovery was achieved one month later. Then, he started treatment with abiraterone, but two weeks later neutropenia reappeared. Abiraterone was withdrawn, and the patient recovered from neutropenia 2 weeks later. MANAGEMENT AND OUTCOMES: This case exposes not only the occurrence of rare toxicity of two individual drugs but also the description of a probable drug-class adverse event not reported before. The patient recovered from neutropenia after the androgen receptor pathway inhibitor was withdrawn, thereby supporting the diagnosis of probable drug-induced neutropenia. DISCUSSION: There is scarce evidence in the literature concerning androgen receptor pathway inhibitor-related neutropenia. However, its life-threatening potential cannot be ignored, so healthcare professionals should be warned of the possibility of the occurrence of such adverse reactions.
RESUMO
Cardiorenal syndrome (CRS) involves joint dysfunction of the heart and kidney. Acute forms share biochemical alterations like hyperuricaemia (HU) with tumour lysis syndrome (TLS). The mainstay treatment of acute CRS with systemic overload is diuretics, but rasburicase is used in TLS to prevent and treat hyperuricaemia. An observational, retrospective study was performed to assess the effectiveness and safety of a single dose of rasburicase in hospitalized patients with cardiorenal syndrome, worsening renal function and uric acid levels above 9 mg/dL. Rasburicase improved diuresis and systemic congestion in the 35 patients included. A total of 86% of patients did not need to undergo RRT, and early withdrawal was possible in the remaining five. Creatinine (Cr) decreased after treatment with rasburicase from a peak of 3.6 ± 1.27 to 1.79 ± 0.83 mg/dL, and the estimated glomerular filtration rate (eGFR) improved from 17 ± 8 to 41 ± 20 mL/min/1.73 m2 (p = 0.0001). The levels of N-terminal type B Brain Natriuretic Peptide (Nt-ProBNP) and C-reactive protein (CRP) were also significantly reduced. No relevant adverse events were detected. Our results show that early treatment with a dose of rasburicase in patients with CRS and severe HU is effective to improve renal function and systemic congestion, avoiding the need for sustained extrarenal clearance, regardless of comorbidities and ventricular function.

BACKGROUND/AIMS: Changes in gene expression profiles among individuals with inflammatory bowel diseases (IBDs) could potentially influence the responsiveness to anti-TNF treatment. The aim of this study was to identify genes that could serve as predictors of early response to anti-TNF therapies in pediatric IBD patients prior to the initiation of treatment. METHODS: We conducted a prospective, longitudinal, and multicenter study, enrolling 24 pediatric IBD patients aged less than 18 years who were initiating treatment with either infliximab or adalimumab. RNA-seq from blood samples was analyzed using the DESeq2 library by comparing responders and non-responders to anti-TNF drugs. RESULTS: Bioinformatic analyses unveiled 102 differentially expressed genes, with 99 genes exhibiting higher expression in responders compared to non-responders prior to the initiation of anti-TNF therapy. Functional enrichment analyses highlighted defense response to Gram-negative bacteria (FDR = 2.3 ×10-7) as the most significant biological processes, and hemoglobin binding (FDR = 0.002), as the most significant molecular function. Gene Set Enrichment Analysis (GSEA) revealed notable enrichment in transcriptional misregulation in cancer (FDR = 0.016). Notably, 13 genes (CEACAM8, CEACAM6, CILP2, COL17A1, OLFM4, INHBA, LCN2, LTF, MMP8, DEFA4, PRTN3, AZU1, and ELANE) were selected for validation, and a consistent trend of increased expression in responders prior to drug administration was observed for most of these genes, with findings for 4 of them being statistically significant (CEACAM8, LCN2, LTF2, and PRTN3). CONCLUSIONS: We identified 102 differentially expressed genes involved in the response to anti-TNF drugs in children with IBDs and validated CEACAM8, LCN2, LTF2, and PRTN3. Genes participating in defense response to Gram-negative bacterium, serine-type endopeptidase activity, and transcriptional misregulation in cancer are good candidates for anticipating the response to anti-TNF drugs in children with IBDs.

BACKGROUND: Patients with hematological malignancies (HM) are at high risk of COVID-19 progression. Hence, early treatments to prevent progression are needed. The aim of our work was to evaluate the effectiveness and safety of remdesivir (RDV) and SARS-CoV-2 monoclonal antibodies (mAb) in patients with HM and mild-to-moderate disease in real clinical practice. METHODS: We conducted a prospective study in a tertiary hospital in 55 HM patients with mild-to-moderate SARS-CoV-2 disease diagnosed between August 2021 and July 2022 and who received RDV or mAb to prevent COVID-19 progression (related death or hospitalization). The primary endpoint was COVID-19 progression on day 28. Other outcomes were COVID-19 progression beyond day 28 and viral load evolution. RESULTS: RDV was administered to 44 (80.0%) patients and mAb to 11 (20.0%) patients. Death occurred in 1 (1.8%) patient and hospitalization in 9 (16.4%) patients by day 28, respectively; 3 patients (5.5%) required intensive care and 8 (14.5%), oxygen support. Of note, 5 additional patients [15, (27.3%) in total] died or required hospitalization after day 28. Two hazard Cox regression models yielded the absence of anti-SARS-CoV-2 antibodies, age over 65 years, and ECOG-performance status ≥ 2 as the main risk factors for COVID-19-related death or hospitalization. CONCLUSION: Our results from clinical practice suggest that RDV and SARS-CoV-2 mAb therapies elicit worse outcomes in hematological patients than those reported for high-risk population in clinical trials.

Few genetic polymorphisms predict early response to anti-TNF drugs in inflammatory bowel disease (IBD), and even fewer have been identified in the pediatric population. However, it would be of considerable clinical interest to identify and validate genetic biomarkers of long-term response. Therefore, the aim of the study was to analyze the usefulness of biomarkers of response to anti-TNFs in pediatric IBD (pIBD) as long-term biomarkers and to find differences by type of IBD and type of anti-TNF drug. The study population comprised 340 children diagnosed with IBD who were treated with infliximab or adalimumab. Genotyping of 9 selected SNPs for their association with early response and/or immunogenicity to anti-TNFs was performed using real-time PCR. Variants C rs10508884 (CXCL12), A rs2241880 (ATG16L1), and T rs6100556 (PHACTR3) (p value 0.049; p value 0.03; p value 0.031) were associated with worse long-term response to anti-TNFs in pIBD. DNA variants specific to disease type and anti-TNF type were identified in the pediatric population. Genotyping of these genetic variants before initiation of anti-TNFs would enable, if validated in a prospective cohort, the identification of pediatric patients who are long-term responders to this therapy.

The perioperative setting is one of the hospital areas with the highest prevalence of medication errors. Despite the wide experience of hospital pharmacists in developing medication safety programs and improvement initiatives, the surgical environment has remained one of the areas in which there is less experience. Clinical pharmacist should be integrated into the multidisciplinary care teams so that they can be involved in the different surgical phases of care, which include from the preoperative assessment to inpatient stay, and finally discharge from hospital. Their work will consist of coordinating and implementing strategies that have been demonstrated to reduce medication errors throughout the perioperative process. The aim of this paper is to introduce a specialized pharmaceutical care program to achieve excellence in the pharmaceutical care of surgical patients. This program is especially aimed at promoting the figure of the clinical pharmacist in the perioperative setting to guarantee the highest quality and safety in pharmacotherapeutic care throughout all the surgical phases of care.

The genetic polymorphisms rs2395185 and rs2097432 in HLA genes have been associated with the response to anti-TNF treatment in inflammatory bowel disease (IBD). The aim was to analyze the association between these variants and the long-term response to anti-TNF drugs in pediatric IBD. We performed an observational, multicenter, ambispective study in which we selected 340 IBD patients under 18 years of age diagnosed with IBD and treated with anti-TNF drugs from a network of Spanish hospitals. Genotypes and failure of anti-TNF drugs were analyzed using Kaplan-Meier curves and Cox logistic regression. The homozygous G allele of rs2395185 and the C allele of rs2097432 were associated with impaired long-term response to anti-TNF drugs in children with IBD after 3 and 9 years of follow-up. Being a carrier of both polymorphisms increased the risk of anti-TNF failure. The SNP rs2395185 but not rs2097432 was associated with response to infliximab in adults with CD treated with infliximab but not in children after 3 or 9 years of follow-up. Conclusions: SNPs rs2395185 and rs2097432 were associated with a long-term response to anti-TNFs in IBD in Spanish children. Differences between adults and children were observed in patients diagnosed with CD and treated with infliximab.

Objective: This study aims to analyze the impact of the eOncosalud app on the management and follow-up of adverse effects (AE) in patients receiving oral antineoplastic agents. Material and methods: We performed an observational, prospective study of cancer outpatients treated with oral antineoplastic agents (OAA), monitored by the eOncosalud app between August 2017 and October 2021. Safety variables were collected from eOncosalud: the number of AE; severity of the AE according to CTCAE, version 4.03; timelapse from app installation to first recorded AE; automatic recommendations issued; and the patient's acceptance of the recommendations made. To assess the impact of the recommendations generated by the algorithm, we calculated the positive predictive value (PPV) as the number of recommendations accepted out of the total number of recommendations generated. Safety-related patient messages were also analyzed (AE, drug-drug interactions, drug administration). Result: The app was downloaded and used by 186 patients (58.0% women), with a mean age of 59.0 years. A total of 1,368 AE were recorded, the most frequent being fatigue (19.37%), diarrhea (18.20%), and skin changes (9.21%). Regarding the recommendations issued by the app algorithm, 102 patients received 344 information brochures, 39 patients received 51 recommendations for supportive care to control AE, 60 patients received 240 recommendations to visit their primary care doctor, 14 patients received 16 recommendations to contact their specialist pharmacist or oncologist-hematologist, and 34 patients received 73 recommendations to go to the emergency room. The suggestion to go to the emergency room and contact the specialist pharmacist or oncologist-hematologist had a PPV of 0.51 and 0.35, respectively. Half of the patients (50.4%) used the messaging module. A total of 1,668 messages were sent. Of these, 47.8% were related to treatment safety: AE, 22.7%; drug-drug interactions, 20.6%; drug administration, 3.6%; and missing a dose, 1.0%. Conclusions: The eOncosalud app enables close, real-time monitoring of patients treated with OAA. The automatic recommendations through the app's algorithm have optimized available healthcare resources. The app facilitated early detection of AE, thus enabling patients themselves to improve the safety of their treatment.

BACKGROUND: The variant rs34983651 (UGT1A1*28) and its genotyping are used to prevent irinotecan-induced toxicity. Several variants are in close linkage disequilibrium. Our objective was to evaluate the potential correlation of genotyping UGT1A1*80 instead of UGT1A1*28 in different populations. METHODS: We studied SNPs in linkage disequilibrium with UGT1A1*28 in several populations and selected rs887829 to develop an inexpensive and rapid genotyping method and compare it with the one we currently use for UGT1A1*28 genotyping. Samples from cancer patients (n = 701) already tested using PCR and electrophoresis prior to treatment with irinotecan for rs34983651 (UGT1A1*28) in a Spanish hospital were genotyped for rs887829 (UGT1A1*80) using real-time PCR with a TaqMan probe. RESULTS: We observed a complete match for both genotypes, except in one sample. This method was 100% efficient in correctly genotyping *28/*28 patients, 99.68% efficient for *1/*28, and 100% efficient for *1/*1. Linkage disequilibrium between populations showed the Iberian population to be the most suitable for the clinical use of UGT1A1*80. This method is less expensive and the time to decision is shorter. CONCLUSION: Genotyping of rs887829 using the proposed method may be used to substitute genotyping of rs34983651 as a pharmacogenetics test in cancer patients prior to starting irinotecan-based treatments, mainly in the Iberian population. In addition, it is less expensive than other conventional methods and easy to implement, with a shorter time to decision than UGT1A1*28.
RESUMO
OBJECTIVE: To review the evidence of the mobile apps in collection patient- reported outcomes and their impact on health outcomes. Method: A review was conducted of the literature on apps aimed at collecting patient-reported outcomes. Selected articles were required to consider the apps' impact on patients' health outcomes. The search was carried out during April 2021 in Pubmed and Embase using the search terms "app", "mobile applications" , "patient-reported outcomes", "outcome assessment, health care", and "quality of life", To be included articles had to be written in English or Spanish and they were required to dwell on apps used by patients, family members and/or caregivers that measured at least one health outcome. No time restrictions were applied. RESULTS: Of the 26 articles reviewed, 19 (73.1%) were clinical trials, 4 (15.4%) were quasi-experimental studies, and 3 (11.5%) were observational studies. A pharmacy department was involved in 4 studies (15.4%), and 3 (11.5%), were carried out in Spain. The sample size ranged from 14 to 411. Depending on the study population, the most frequent studies included cancer patients (42.3%) and patients with cardiovascular diseases (26.9%). Most of the studies focused on measuring the impact of the app on the patients' quality of life (50.0%), control of clinical parameters (46.2%), adherence (38.5%), and management of symptoms and/or reduction of complications (26.9%). Overall efficacy in terms of the percentage of studies where apps were found to result in a significant improvement was 73.1%. The most heavily impacted patient-reported outcomes were adherence, health-related quality of life and satisfaction. CONCLUSIONS: There is emerging evidence that apps have a positive impact on patients' health outcomes. These tools have shown to lead to an improvement in the management of different conditions, with results showing a reduction in complications rates and in the consumption of resources as well as better adherence to medication and enhanced patient quality of life.

BACKGROUND: Hematological conditions are prevalent disorders that are associated with significant comorbidities and have a major impact on patient care. Concerning new tools for the care of these patients, the number of health apps aimed at hematological patients is growing. Currently, there are no quality analyses or classifications of apps for patients diagnosed with hematological conditions. OBJECTIVE: The aim of this study is to analyze the characteristics and quality of apps designed for patients diagnosed with hematological conditions by using the Mobile App Rating Scale (MARS). METHODS: We performed an observational, cross-sectional descriptive study of all smartphone apps for patients diagnosed with hematological conditions. A search was conducted in March 2021 using the following terms: anemia, blood cancer, blood disorder, hematological cancer, hematological malignancy, hematological tumor, hematology, hemophilia, hemorrhage, lymphoma, leukemia, multiple myeloma, thalassemia, thrombocytopenia, and thrombosis. The apps identified were downloaded and evaluated by 2 independent researchers. General characteristics were registered, and quality was analyzed using MARS scores. Interrater reliability was measured by using the Cohen κ coefficient. RESULTS: We identified 2100 apps in the initial search, and 4.19% (88/2100) of apps met the inclusion criteria and were analyzed. Of the 88 apps, 61% (54/88) were available on Android, 30% (26/88) were available on iOS, and 9% (8/88) were available on both platforms. Moreover, 7% (6/88) required payment, and 49% (43/88) were updated in the last year. Only 26% (23/88) of the apps were developed with the participation of health professionals. Most apps were informative (60/88, 68%), followed by preventive (23/88, 26%) and diagnostic (5/88, 6%). Most of the apps were intended for patients with anemia (23/88, 26%). The mean MARS score for the overall quality of the 88 apps was 3.03 (SD 1.14), ranging from 1.19 (lowest-rated app) to 4.86 (highest-rated app). Only 47% (41/88) of the apps obtained a MARS score of over 3 points (acceptable quality). Functionality was the best-rated section, followed by aesthetics, engagement, information, and app subjective quality. The five apps with the highest MARS score were the following: Multiple Myeloma Manager, Hodgkin Lymphoma Manager, Focus On Lymphoma, ALL Manager, and CLL Manager. The analysis by operating system, developer, and cost revealed statistically significant differences in MARS scores (P<.001, P<.001, and P=.049, respectively). The interrater agreement between the 2 reviewers was substantial (k=0.78). CONCLUSIONS: There is great heterogeneity in the quality of apps for patients with hematological conditions. More than half of the apps do not meet acceptable criteria for quality and content. Most of them only provide information about the pathology, lacking interactivity and personalization options. The participation of health professionals in the development of these apps is low, although it is narrowly related to better quality.

Dihydropyrimidine dehydrogenase deficiency is a major cause of severe fluoropyrimidine-induced toxicity and could lead to interruption of chemotherapy or life-threatening adverse reactions. This study aimed to characterize the DPYD exon sequence, mRNA expression and in vivo DPD activity by plasma uracil concentration. It was carried out in two groups of patients with extreme phenotypes (toxicity versus control) newly treated with a fluoropyrimidine, during the first three cycles of treatment. A novel nonsense gene variant (c.2197insA) was most likely responsible for fluoropyrimidine-induced toxicity in one patient, while neither DPYD mRNA expression nor plasma uracil concentration was globally associated with early toxicity. Our present work may help improve pharmacogenetic testing to avoid severe and undesirable adverse reactions to fluoropyrimidine treatment and it also supports the idea of looking beyond DPYD.
RESUMO
PURPOSE: The use process for chimeric antigen receptor T (CAR-T) cell drugs is complex and has been associated with a number of potentially severe complications, which requires management by a multidisciplinary team. Pharmacists are a key element in the team and have roles and responsibilities. Our objective was to develop a structured and practical guide that supports hospital pharmacist responsibilities and defines specific activities in a CAR-T cell therapy program, specifically in Europe. METHODS: A literature review was performed, and the recommendations related to pharmacy practice in CAR-T therapy programs were analyzed. A multidisciplinary team was assembled, and meetings were held to address the key tasks in the CAR-T cells' management process and to create the guide, based on national and international recommendations and in expert's opinions. RESULTS: The multidisciplinary team defined the following key tasks and issued recommendations to improve patient safety, treatment efficacy, and quality: patient selection and evaluation, CAR-T cell drug order to manufacturer, apheresis and material shipment, reception of CAR-T cell drug and storing, CAR-T cell drug prescription and pharmacy verification, CAR-T cell drug thawing and dispensing, CAR-T cell drug administration, patient education, pharmacovigilance and monitoring and outcomes' record and evaluation. In each task the pharmacist's role and how it can improve patient care are defined. A checklist was created to guarantee the compliance of standard operating procedures approved in the institution to manage CAR-T cell therapy and as a tool to collect required data for outcomes' record and evaluation. CONCLUSION: This article provides a consensus set of safety recommendations regarding CAR-T therapy management in clinical practice, easily implementable by other institutions in the European setting. The guide identifies key steps where the involvement of hospital pharmacists would improve the safety and quality of the process and is a support guide to standardize hospital pharmacists' responsibilities within the multidisciplinary team.
RESUMO
BACKGROUND: Up to 30% of patients with pediatric inflammatory bowel disease (IBD) do not respond to anti-Tumor Necrosis Factor (anti-TNF) therapy. The aim of this study was to identify pharmacogenomic markers that predict early response to anti-TNF drugs in pediatric patients with IBD. METHODS: An observational, longitudinal, prospective cohort study was conducted. The study population comprised 38 patients with IBD aged < 18 years who started treatment with infliximab or adalimumab (29 responders and nine non-responders). Whole gene expression profiles from total RNA isolated from whole blood samples of six responders and six non-responders taken before administration of the biologic and after two weeks of therapy were analyzed using next-generation RNA sequencing. The expression of six selected genes was measured for purposes of validation in all of the 38 patients recruited using qPCR. RESULTS: Genes were differentially expressed in non-responders and responders (32 before initiation of treatment and 44 after two weeks, Log2FC (Fold change) >0.6 or <-0.6 and p value < 0.05). After validation, FCGR1A, FCGR1B, and GBP1 were overexpressed in non-responders two weeks after initiation of anti-TNF treatment (Log2FC 1.05, 1.21, and 1.08, respectively, p value < 0.05). CONCLUSION: Expression of the FCGR1A, FCGR1B, and GBP1 genes is a pharmacogenomic biomarker of early response to anti-TNF agents in pediatric IBD.
RESUMO
INTRODUCTION: Acute graft-versus-host disease GVHD (aGVHD) is the main complication during the first months after bone transplantation. Steroid therapy is clearly the upfront established treatment for aGVHD. However, there are patients with partial response to steroid treatment and steroid-refractory cases. For those patients, a vast number of therapeutic options have emerged, although the evidence is scarce. CASE REPORT: We report the use of tocilizumab as salvage treatment in a patient with corticosteroid refractory pulmonary aGVHD that was admitted to the critical care unit for respiratory support measures. MANAGEMENT & OUTCOME: We decided to use tocilizumab as rescue treatment, after failure of corticosteroid treatment, standard treatment with broad-spectrum antibiotics and etanercept. The patient showed a remarkable clinical improvement two days after first infusion and a total resolution of the symptomatology with normalization of the spirometry tests after 4 weeks of the administration of tocilizumab. DISCUSSION: To the authors' knowledge, this is the first case that describes the effective and safe use of tocilizumab as a rescue treatment in a patient with steroid-refractory pulmonary aGVHD. It showed a rapid onset of action and a favorable safety profile, which could make it an interesting option for the treatment of this potentially fatal complication.

AIMS: Identifying DNA variants associated with trough serum anti-tumour necrosis factor (TNF) levels could predict response to treatment in inflammatory bowel disease (IBD). To date, no specific studies have been performed in children. The aim of this study was to identify genetic variants associated with trough serum anti-TNF levels and whether these variants are differential markers for infliximab and adalimumab. METHODS: We included 154 children (age < 18 years) from 17 hospitals who had been diagnosed with IBD and actively treated with infliximab or adalimumab. Twenty-one polymorphisms were genotyped using real-time PCR. Trough serum anti-TNF levels were measured using enzyme-linked immunosorbent assay (ELISA). The association between DNA polymorphisms and the therapeutic range or the absolute values of anti-TNF drugs was analysed by Fisher exact test, student's t-test and logistic regression. RESULTS: The variants rs5030728 (TLR4) and rs11465996 (LY96) were associated with subtherapeutic infliximab levels. rs1816702 (TLR2) was associated with supratherapeutic levels and rs3397 (TNFRSF1B) with subtherapeutic levels of adalimumab (P < .05). In addition, rs1816702 (TLR2) and rs2569190 (CD14) were associated with absolute values of trough serum adalimumab, and rs2569190 (CD14) was associated with absolute values of trough serum adalimumab and infliximab (P < .05). CONCLUSION: Genotyping of these DNA variants before starting treatment may help to select the best anti-TNF drug in paediatric patients. The SNP rs1816702 is the most promising marker for tailoring the anti-TNF regimen in children with IBD. For the first time, DNA variants are associated with trough serum anti-TNF levels.

INTRODUCTION: Cerebellar mutism syndrome (CMS) is a common complication after posterior fossa tumor resection. It is characterized by a significant lack or loss of speech. Its biological origin remains unclear and there are no standardized treatments. However, bromocriptine seems to be a possible treatment for this condition. CASE REPORT: In this paper, we present three cases of pediatric patients (4, 5, and 17-year old) who developed CMS after posterior fossa tumor surgery. They were treated with bromocriptine to improve neurological symptoms.Management and outcome: Bromocriptine was started at a low dose and was progressively increased to reach the minimum effective dose. After four months of treatment, a normal and fluid speech was observed in the three patients. No discontinuation due to adverse events were reported. DISCUSSION: Bromocriptine has shown to be an effective and safe treatment for CMS in pediatric patients after posterior fossa tumor resection.

BACKGROUND: Oral antineoplastic agents (OAAs) have revolutionized cancer management. However, they have been reported with adverse side effects and drug-drug interactions. Moreover, patient adherence to OAA treatment is critical. Mobile apps can enable remote and real-time pharmacotherapeutic monitoring of patients, while also promoting patient autonomy in their health care. OBJECTIVE: The primary objective was to analyze the effect of using a mobile app for the follow-up of patients with oncohematological malignancies undergoing treatment with OAAs on their health outcomes. The secondary objectives were to analyze the role of the app in communication with health care professionals and patient satisfaction with the app. METHODS: We performed a comparative, quasi-experimental study based on a prepost intervention with 101 patients (control group, n=51, traditional pharmacotherapeutic follow-up vs intervention group, n=50, follow-up through e-OncoSalud, a custom-designed app that promotes follow-up at home and the safety of patients receiving OAAs). The effect of this app on drug safety, adherence to treatment, and quality of life was evaluated. RESULTS: With regard to drug safety, 73% (37/51) of the patients in the control group and 70% (35/50) of the patients in the intervention group (P=.01) presented with drug-related problems. The probability of detecting an insufficiently treated health problem in the intervention group was significantly higher than that in the control group (P=.04). The proportion of patients who presented with side effects in the intervention group was significantly lower than that in the control group (P>.99). In the control group, 49% (25/51) of the patients consumed some health resources during the first 6 months of treatment compared with 36% (18/50) of the patients in the intervention group (P=.76). Adherence to treatment was 97.6% (SD 7.9) in the intervention group, which was significantly higher than that in the control group (92.9% [SD 10.0]; P=.02). The EuroQol-5D in the intervention group yielded a mean (SD) index of 0.875 (0.156), which was significantly higher than that in the control group (0.741 [0.177]; P<.001). Approximately 60% (29/50) of the patients used the messaging module to communicate with pharmacists. The most frequent types of messages were acknowledgments (77/283, 27.2%), doubts about contraindications and interactions with OAAs (70/283, 24.7%), and consultations for adverse reactions to treatment (39/283, 13.8%). The satisfaction with the app survey conducted in the intervention group yielded an overall mean (SD) score of 9.1 (0.4) out of 10. CONCLUSIONS: Use of e-OncoSalud for the real-time follow-up of patients receiving OAAs facilitated the optimization of some health outcomes. The intervention group had significantly higher health-related quality of life and adherence to treatment than the control group. Further, the probability of the intervention group presenting with side effects was significantly lower than that of the control group.

OBJECTIVES: To evaluate the use, effectiveness and safety of tyrosine kinase inhibitors (TKIs) for chronic myelogenous leukaemia (CML) in clinical practice. METHODS: A retrospective longitudinal study of patients with CML who received TKIs for at least 6 months was performed. Endpoints to evaluate effectiveness were haematological, cytogenetic and molecular responses. Safety was assessed according to the occurrence of adverse events. RESULTS: Sixty-two patients were included. All received imatinib as the initial TKI; 8% switched to nilotinib due to lack of major molecular response (MMR) to imatinib and 3% switched to dasatinib because of progression to blast crisis or lack of MMR. At the end of the study all patients had achieved at least a complete cytogenetic response. With regard to safety, in 11 patients the dose of imatinib was decreased and four patients switched to a second-generation TKI due to imatinib toxicity. CONCLUSIONS: Considering the good responses of most patients and its better known safety profile, imatinib should remain a good option for first-line treatment of CML.
