The Real-World Effectiveness, Persistence, Adherence, and Safety of Janus Kinase Inhibitor Baricitinib in Rheumatoid Arthritis: A Long-Term Study.

Background/Aim: Baricitinib (BAR) is the first oral selective Janus kinase inhibitor approved in Europe for rheumatoid arthritis (RA). Real-world data are still needed to clarify its long-term benefits/risk profile. This study aimed to evaluate the effectiveness, persistence, adherence, and safety of BAR in a real-world setting. Methods: An ambispective study was conducted between October 2017 and December 2021 in RA patients starting BAR. The effectiveness was evaluated, assessing changes from the baseline of the Disease Activity Score using 28-joint counts-C reactive protein (DAS28CRP), and the achievement of low disease activity/remission. Drug persistence was evaluated using Kaplan-Meier analysis. Adherence was estimated using the medication possession ratio (MPR) and the 5-item Compliance Questionnaire for Rheumatology. Safety was assessed determining global incidence proportion and adverse event adjusted incidence rates. Results: In total, 61/64 recruited patients were finally analyzed, 83.6% were female, 78.7% were seropositive, the mean age was 58.1 (15.4) years, and the disease duration was 13.9 (8.3) years. A total of 32.8% of patients were naïve to biologics and 16.4% received BAR as monotherapy. The median exposure to BAR was 12.4 (6.6-31.2) months (range 3.1-51.4). A significant change in DAS28CRP was observed after treatment (difference -1.2, p = 0.000). 70.5% and 60.7% of patients achieved low disease activity or remission, respectively, and 50.8% (31/61) remained on BAR throughout the follow-up, with a median persistence of 31.2 (9.3-53.1) months. The average MPR was 0.96 (0.08) and all patients exhibited "good adherence" according to the questionnaire. In total, 21.3% of patients discontinued baricitinib due to toxicity. Conclusions: In our real-world practice, BAR demonstrated effectiveness, large persistence, high adherence to treatment, and an acceptable safety profile.

Anti-interleukin-17 therapies for moderate/severe psoriasis in clinical practice: effectiveness, safety and association with clinical patient factors.

OBJECTIVES: Interleukin-17 (IL-17) contributes to the pathogenesis of psoriasis. Secukinumab, ixekizumab, and brodalumab are monoclonal antibodies anti-IL-17 antibodies, approved for the treatment of moderate/severe plaque psoriasis.The aim of the study was to describe the effectiveness and safety of anti-IL-17 agents in moderate/severe plaque psoriasis in clinical practice. We also analysed anti-IL-17 therapies' survival, dose adjustment, and clinical patients' factors associated with their effectiveness and safety. METHODS: A retrospective, longitudinal study was conducted at a tertiary hospital. We included patients with moderate/severe psoriasis treated with anti-IL-17 agents. The effectiveness was evaluated with Psoriasis Area and Severity Index (PASI) score and safety through the adverse drug reactions (ADRs) collected. RESULTS: 38 patients were studied (median age=47.4 years, 71.0% male). The mean number of biological therapies that patients received was 2.6, and anti-IL-17 therapy was the first biological therapy for 36.8% of patients. The median years in treatment were 2.5 (95% CI 1.95 to 2.98) for secukinumab, 1.2 (95% CI 0.36 to 1.47) for ixekizumab, and 0.7 (IQR 0.71) for brodalumab. The median PASI score after 6 months of treatment was 0 (IQR 0) and 85.3% of patients achieved a PASI of 90 (84.0% with secukinumab, 87.5% with ixekizumab, and 100% with brodalumab). Dose adjustment was associated with the line of treatment (p=0.034 for naïve patients), age (p=0.044 for younger patients), and concomitant pathologies (p=0.015 without more diseases).24 patients suffered from ADRs, mainly infections of the upper respiratory tract, and there were no statistically significant differences between the three therapies. CONCLUSIONS: Anti-IL-17 agents constitute an effective treatment for patients with moderate/severe plaque psoriasis and for longer. Dose reductions were associated with fewer lines of treatment, younger patients and absence of concomitant pathologies. ADR were minor and similar among the anti-IL-17.

Development of a telematic pharmaceutical care app (Haemoassist) for multidisciplinary follow-up of patients with congenital coagulopathies.

BACKGROUND: Guidelines for congenital coagulopathies recommend that patients record treatment administrations and bleeding episodes to help healthcare professionals monitor the disease. RESEARCH DESIGN AND METHODS: We studied over two years which patient profiles (age, treatment regimen, treatment compliance) were most likely to accept the use of an app to collect this information. We validated the quality of patient-reported data by comparing it with data obtained from hospital electronic records, pharmacy dispensing records and patient interview, collected in an access database used as a reference. Patient and professional opinions were solicited through open-ended interviews. RESULTS: The app was used by 52% of 315 patients studied. Younger patients were the most frequent users. Patients with better treatment compliance used the app more, although data collection was incomplete for most patients. The best rated by patients were the reminders of days of administration and the minimum stock alerts at home. Healthcare professionals rated the app positively. CONCLUSIONS: Healthcare professionals valued the app as useful for managing treatment of congenital coagulopathies. Patients need support and time to use the app and improve the quality of the data entered. Patients who used the app rated it positively. The treatment compliance improved.

Real-world outcomes of abiraterone and enzalutamide in first-line treatment of metastatic castration-resistant prostate cancer: which patients benefit most?

OBJECTIVES: Abiraterone and enzalutamide are two oral novel androgen receptor axis-targeted agents approved for the treatment of castration-resistant prostate cancer (mCRPC). Despite the availability of multiple treatments, there is a need to improve the knowledge and management of these drugs in the real-world setting, especially in patient groups under-represented in clinical trials. Our aim was to review the outcome of patients with chemotherapy-naïve mCRPC treated with abiraterone or enzalutamide in routine clinical practice in order to identify factors that are predictive for response. METHODS: This observational retrospective study was performed in a Spanish tertiary hospital and included men with chemotherapy-naïve mCPRC who started treatment with abiraterone or enzalutamide between September 2012 and November 2018. The study end date was 30 October 2020. RESULTS: Ninety patients with mCRPC were included, 57 with abiraterone and 33 with enzalutamide. Median overall survival (OS) was 26.87 months (95% CI 19.68 to 34.05), with no difference found between the two treatment groups. Nine variables were related to increased OS in the univariate analysis: Eastern Cooperative Oncology Group (ECOG) performance status (0-1 vs 2), pain (need of opioids for cancer pain), visceral disease, ≥3 bone lesions, exclusively lymph node metastases, baseline prostate specific antigen (PSA) (<50 vs ≥50 ng/dL and <20 vs ≥20 ng/dL), haemoglobin (<12 vs ≥12 g/dL) and alkaline phosphatase (≤116 vs >116 IU/L). A PSA response >50% was observed in 65 patients (76.5%). In the multivariate analysis, ECOG performance status, pain, visceral disease and alkaline phosphatase provided independent prognostic information. Median OS by Kaplan-Meier analysis was significantly longer for patients with a PSA response (32.1 vs 17.9 months; HR 0.46, 95% CI 0.27 to 0.78; p=0.003). CONCLUSIONS: This study assessed the efficacy of abiraterone and enzalutamide in a real-world setting, including patients under-represented in pivotal studies. Some clinical factors were correlated with improved OS in chemotherapy-naïve men with mCPRC treated with these drugs.

Intervention by a clinical pharmacist carried out at discharge of elderly patients admitted to the internal medicine department: influence on readmissions and costs.

BACKGROUND: Patient education on pharmacological treatment could reduce readmissions. Our objective was to carry out a pharmacist intervention focused on providing information about high-risk medications to chronic patients and to analyse its influence on readmissions and costs. METHODS: A single-centre study with an intervention group and a retrospective control group was conducted. The intervention was carried out in all polymedicated patients ≥ 65 years who were admitted to internal medicine and signed the informed consent between June 2017 and February 2018. Patients discharged to nursing homes or long-term hospitals were excluded. The control group were all the patients who were admitted during the same months of 2014 who met the same inclusion criteria. The patients were classified according to the HOSPITAL score as having a low, intermediate, or high risk of potentially avoidable readmission. Outcome measures were 30-day readmission and cost data. To analyse the effect of the intervention on readmission, a logistic regression was performed. RESULTS: The study included 589 patients (286 intervention group; 303 control group). The readmission rate decreased from 20.13% to 16.43% in the intervention group [OR = 0.760 95% CI (0.495-1.166); p = 0.209)]. The incremental cost for the intervention to prevent one readmission was €3,091.19, and the net cost saving was €1,301.26. In the intermediate- and high-risk groups, readmissions were reduced 10.91% and 10.00%, and the net cost savings were €3,3143.15 and €3,248.71, respectively. CONCLUSIONS: The pharmacist intervention achieved savings in the number of readmissions, and the net cost savings were greater in patients with intermediate and high risks of potentially avoidable readmission according to the HOSPITAL score.

Safety and effectiveness of a four-factor prothrombin complex concentrate for vitamin K antagonist reversal following a fixed-dose strategy.

OBJECTIVES: Early reversal of anticoagulation improves outcomes in major bleeding and emergency surgery. To reverse vitamin K antagonists (VKA), vitamin K in addition to prothrombin complex concentrate (PCC) is recommended. Dosing recommendations for VKA reversal provided by the manufacturer are 25-50 IU/kg depending on the baseline international normalised ratio (INR). Nevertheless, we recommend an initial fixed dose of 1000 IU, and additional 500 IU doses evaluated on a case-by-case basis. As there is a paucity of clinical data demonstrating the efficacy and safety of this strategy, we designed this study to assess the effectiveness and safety of a four-factor (4F)-PCC for VKA reversal following a fixed-dose strategy. METHODS: This was a retrospective study of adult patients who received 4F-PCC for VKA reversal. The primary outcome was INR correction. INR correction was achieved if the first INR draw after 4F-PCC was ≤1.5. Safety outcome was any confirmed thromboembolic event within 3 months after 4F-PCC. Secondary outcomes included activated partial thromboplastin time (aPTT) correction, as well as haemostatic effectiveness for bleeding patients. RESULTS: A total of 145 patients were included: 106 (73.1%) in the bleeding group and 39 (26.9%) in the emergency surgery group. The INR target was reached in 102 (70.3%) patients (p<0.0001). In one case, a thromboembolic complication was possibly related to 4F-PCC. The aPTT ratio target was reached in 113 (77.9%) patients (p<0.0001), and 79 of the 106 (74.5%) patients reversed for bleeding achieved haemostatic effectiveness. CONCLUSIONS: After 4F-PCC, the majority of patients achieved the target INR, meaning 4F-PCC is a useful modality for rapid INR reduction. The safety profile may be considered acceptable. Fixed-dose 4F-PCC was able to restore haemostasis rapidly while minimising the risk of adverse events and optimising available resources.

Off-Label and Unlicensed Drugs in Pediatric Palliative Care: A Prospective Observational Study.

CONTEXT: Off-label and unlicensed use of drugs is a widespread practice in pediatric care because of the lack of specific efficacy and safety data and the absence of formulations adapted to the needs of these individuals. Pediatric patients with a life-limiting illness frequently receive drugs under these conditions, although no studies have established the prevalence of this practice. OBJECTIVES: To describe the prevalence, indications, and most common uses of off-label and unlicensed drugs in a pediatric palliative care unit (PPCU). METHODS: A prospective cross-sectional observational study carried out between January and October 2019. RESULTS: About 85 patients involving 1198 prescriptions were analyzed. A total of 39.6% were off label, and 12.9% were unlicensed. All received at least one off-label drug, with a median of five per patient (interquartile range 3-7), and 81.2% received at least one unlicensed drug. A total of 36.1% of the prescriptions were considered off label because of indication, 33.8% because of dosage, and 26.6% because of age. The main drugs used off label were oral morphine, oral levetiracetam, inhaled albuterol, sublingual ondansetron, oral tizanidine, sublingual fentanyl, and oral diazepam. The main symptoms treated with off-label drugs were dyspnea, pain, and nausea/vomiting. CONCLUSION: More than half of the prescriptions in this PPCU were off label or unlicensed. Treatment indication was one of the main reasons for off-label use. Administration of compounded preparations was common in patients with a life-limiting illness.

Factors associated with long-term persistence of rituximab in rheumatoid arthritis In clinical practice: RITAR Study. / Factores asociados a la persistencia a largo plazo de rituximab en artritis reumatoide en la práctica clínica: Estudio RITAR.

BACKGROUND AND OBJECTIVE: Treatment of rheumatoid arthritis with rituximab (RTX) requires repeated cycles, but there is no well-established retreatment regimen in dose and frequency. The objective was to analyse the persistence of RTX treatment and factors that influence in terms of routine clinical practice. METHODS: Rituximab in Rheumatoid Arthritis (RITAR Study) is an observational, retrospective study that analyses the persistence of RTX in a cohort from 2003 to 2015. Persistence was calculated by the Kaplan-Meier analysis; curves were compared with the Log-Rank test. Cox regression was used to quantify the risk of discontinuation and multivariate analyses were conducted to determine the factors associated with the persistence of the treatment. RESULTS: 454 cycles of RTX in 114 patients were included. Median survival was 10.0 years and incidence rate of discontinuation was 7.7 per 100 patients/year. Factors associated with persistence were autoantibody positivity and use of RTX in combination with csDMARDs. Sex, age, number of comorbidities, rheumatoid arthritis evolution, number of complications, basal DAS28, basal HAQ, number of lines of treatment, fixed or on demand retreatment and year of RTX starting were not associated. Multivariable models confirmed the relationship between autoantibody positivity, monotherapy and persistence of RTX. CONCLUSIONS: The persistence of RTX in clinical practice is higher in seropositive patients and in those who are treated with RTX associated with a csDMARD. Dose per cycle and retreatment frequency do not have a decisive role in rituximab persistence.

Impact of the implementation of vasoactive drug protocols on costs in the treatment of critically ill patients.

OBJECTIVE: To evaluate the efficiency of the protocolization and centralization of  the preparation of intravenous vasoactive drug mixtures in the treatment of  critically ill patients. METHOD: A prospective interventional study (July 2012-December 2014) was  conducted to measure the impact of different vasoactive drug protocols on costs  in the treatment of critically ill patients. The economic impact was measured by  comparing the direct costs (fixed and variable) of the preparation of intravenous  vasoactive drug mixtures in the Pharmacy Department with their traditional  preparation in hospital care units. The variables time and cost of preparation of  an intravenous mixture were measured. Costs included pharmaceutical product,  diluent, medical supplies, cost of manpower, and use of laminar flow cabinets in  the Pharmacy Department. Costs were measured in Euros. RESULTS: A statistically significant difference was found between processing times in the Pharmacy Department and those in the hospital care unit (2.10 vs 2.86 minutes). Centralized preparation in the Pharmacy Department  was more efficient. The average cost of preparation was €5.24±1.45 in the  Pharmacy Department and €5.62±1.55 in the hospital care unit, although this  difference did not reach statistical significance. If the analysis had included the  cost of intravenous mixtures that had expired prior to their use, the centralized  preparation of the mixtures in the Pharmacy Department would have entailed a  higher cost (€2 174/y). CONCLUSIONS: The centralized preparation of intravenous mixtures in the Pharmacy Department entails significant time savings compared with their preparation in the hospital care unit.

Objetivo: Evaluar la eficiencia de la protocolización y centralización de la  elaboración de mezclas intravenosas de fármacos vasoactivos en el tratamiento  del paciente crítico.Método: Se realizó un estudio prospectivo, de intervención (julio 2012- diciembre 2014) para medir el impacto de la protocolización de mezclas  intravenosas en el coste del tratamiento del paciente crítico. Para realizar el  análisis económico se compararon los costes directos (fijos y variables) de la  preparación de mezclas intravenosas de fármacos vasoactivos en el Servicio de  Farmacia versus preparación en planta. Se midieron las variables tiempo y coste de elaboración de una mezcla intravenosa. Para la determinación del coste final  de elaboración se incluyeron medicamento, diluyente, material fungible,  personal y utilización de las cabinas de flujo laminar. Los costes se midieron en  euros.Resultados: La diferencia encontrada en los tiempos de elaboración entre el  Servicio de Farmacia y la Unidad de Enfermería (2,10 versus 2,86 minutos) fue  estadísticamente significativa y favorable a la elaboración centralizada en el  Servicio de Farmacia. El coste medio de elaboración por mezcla fue 5,24 ± 1,45  euros en el Servicio de Farmacia y 5,62 ± 1,55 euros en planta, aunque la  diferencia encontrada no alcanzó la significación estadística. Al incluir en el  análisis el coste de las mezclas intravenosas caducadas antes de su utilización,  la preparación centralizada en el Servicio de Farmacia supuso un coste superior  (2.174 euros/año).Conclusiones: La elaboración en el Servicio de Farmacia supone un ahorro  significativo de tiempo en comparación con la preparación en planta. La  diferencia de coste de esta alternativa, debida principalmente al impacto de las  mezclas intravenosas caducadas, se eliminaría al optimizar la producción en la  Unidad de Mezclas Intravenosas y al minimizar las pérdidas por caducidad.
